-## Design goals
-
-There are myriads of [JSON](https://json.org) libraries out there, and each may even have its reason to exist. Our class had these design goals:
-
-- **Intuitive syntax**. In languages such as Python, JSON feels like a first class data type. We used all the operator magic of modern C++ to achieve the same feeling in your code. Check out the [examples below](#examples) and you'll know what I mean.
-
-- **Trivial integration**. Our whole code consists of a single header file [`json.hpp`](https://github.com/nlohmann/json/blob/develop/single_include/nlohmann/json.hpp). That's it. No library, no subproject, no dependencies, no complex build system. The class is written in vanilla C++11. All in all, everything should require no adjustment of your compiler flags or project settings.
-
-- **Serious testing**. Our class is heavily [unit-tested](https://github.com/nlohmann/json/tree/develop/test/src) and covers [100%](https://coveralls.io/r/nlohmann/json) of the code, including all exceptional behavior. Furthermore, we checked with [Valgrind](https://valgrind.org) and the [Clang Sanitizers](https://clang.llvm.org/docs/index.html) that there are no memory leaks. [Google OSS-Fuzz](https://github.com/google/oss-fuzz/tree/master/projects/json) additionally runs fuzz tests against all parsers 24/7, effectively executing billions of tests so far. To maintain high quality, the project is following the [Core Infrastructure Initiative (CII) best practices](https://bestpractices.coreinfrastructure.org/projects/289).
-
-Other aspects were not so important to us:
-
-- **Memory efficiency**. Each JSON object has an overhead of one pointer (the maximal size of a union) and one enumeration element (1 byte). The default generalization uses the following C++ data types: `std::string` for strings, `int64_t`, `uint64_t` or `double` for numbers, `std::map` for objects, `std::vector` for arrays, and `bool` for Booleans. However, you can template the generalized class `basic_json` to your needs.
-
-- **Speed**. There are certainly [faster JSON libraries](https://github.com/miloyip/nativejson-benchmark#parsing-time) out there. However, if your goal is to speed up your development by adding JSON support with a single header, then this library is the way to go. If you know how to use a `std::vector` or `std::map`, you are already set.

-## Examples
-
-Beside the examples below, you may want to check the [documentation](https://nlohmann.github.io/json/) where each function contains a separate code example (e.g., check out [`emplace()`](https://nlohmann.github.io/json/api/basic_json/emplace/)). All [example files](https://github.com/nlohmann/json/tree/develop/doc/examples) can be compiled and executed on their own (e.g., file [emplace.cpp](https://github.com/nlohmann/json/blob/develop/doc/examples/emplace.cpp)).
-
-### JSON as first-class data type
-
-Here are some examples to give you an idea how to use the class.
-
-Assume you want to create the JSON object
-
-```json
-{
-  "pi": 3.141,
-  "happy": true,
-  "name": "Niels",
-  "nothing": null,
-  "answer": {
-    "everything": 42
-  },
-  "list": [1, 0, 2],
-  "object": {
-    "currency": "USD",
-    "value": 42.99
-  }
-}
-```
-
-With this library, you could write:
-
-```cpp
-// create an empty structure (null)
-json j;
-
-// add a number that is stored as double (note the implicit conversion of j to an object)
-j["pi"] = 3.141;
-
-// add a Boolean that is stored as bool
-j["happy"] = true;
-
-// add a string that is stored as std::string
-j["name"] = "Niels";
-
-// add another null object by passing nullptr
-j["nothing"] = nullptr;
-
-// add an object inside the object
-j["answer"]["everything"] = 42;
-
-// add an array that is stored as std::vector (using an initializer list)
-j["list"] = { 1, 0, 2 };
-
-// add another object (using an initializer list of pairs)
-j["object"] = { {"currency", "USD"}, {"value", 42.99} };
-
-// instead, you could also write (which looks very similar to the JSON above)
-json j2 = {
-  {"pi", 3.141},
-  {"happy", true},
-  {"name", "Niels"},
-  {"nothing", nullptr},
-  {"answer", {
-    {"everything", 42}
-  }},
-  {"list", {1, 0, 2}},
-  {"object", {
-    {"currency", "USD"},
-    {"value", 42.99}
-  }}
-};
-```
-
-Note that in all these cases, you never need to "tell" the compiler which JSON value type you want to use. If you want to be explicit or express some edge cases, the functions [`json::array()`](https://nlohmann.github.io/json/api/basic_json/array/) and [`json::object()`](https://nlohmann.github.io/json/api/basic_json/object/) will help:
-
-```cpp
-// a way to express the empty array []
-json empty_array_explicit = json::array();
-
-// ways to express the empty object {}
-json empty_object_implicit = json({});
-json empty_object_explicit = json::object();
-
-// a way to express an _array_ of key/value pairs [["currency", "USD"], ["value", 42.99]]
-json array_not_object = json::array({ {"currency", "USD"}, {"value", 42.99} });
-```
-
-### Serialization / Deserialization
-
-#### To/from strings
-
-You can create a JSON value (deserialization) by appending `_json` to a string literal:
-
-```cpp
-// create object from string literal
-json j = "{ \"happy\": true, \"pi\": 3.141 }"_json;
-
-// or even nicer with a raw string literal
-auto j2 = R"(
-  {
-    "happy": true,
-    "pi": 3.141
-  }
-)"_json;
-```
-
-Note that without appending the `_json` suffix, the passed string literal is not parsed, but just used as JSON string value. That is, `json j = "{ \"happy\": true, \"pi\": 3.141 }"` would just store the string `"{ "happy": true, "pi": 3.141 }"` rather than parsing the actual object.
-
-The above example can also be expressed explicitly using [`json::parse()`](https://nlohmann.github.io/json/api/basic_json/parse/):
-
-```cpp
-// parse explicitly
-auto j3 = json::parse(R"({"happy": true, "pi": 3.141})");
-```
-
-You can also get a string representation of a JSON value (serialize):
-
-```cpp
-// explicit conversion to string
-std::string s = j.dump();    // {"happy":true,"pi":3.141}
-
-// serialization with pretty printing
-// pass in the amount of spaces to indent
-std::cout << j.dump(4) << std::endl;
-// {
-//     "happy": true,
-//     "pi": 3.141
-// }
-```
-
-Note the difference between serialization and assignment:
-
-```cpp
-// store a string in a JSON value
-json j_string = "this is a string";
-
-// retrieve the string value
-auto cpp_string = j_string.get<std::string>();
-// retrieve the string value (alternative when a variable already exists)
-std::string cpp_string2;
-j_string.get_to(cpp_string2);
-
-// retrieve the serialized value (explicit JSON serialization)
-std::string serialized_string = j_string.dump();
-
-// output of original string
-std::cout << cpp_string << " == " << cpp_string2 << " == " << j_string.get<std::string>() << '\n';
-// output of serialized value
-std::cout << j_string << " == " << serialized_string << std::endl;
-```
-
-[`.dump()`](https://nlohmann.github.io/json/api/basic_json/dump/) returns the originally stored string value.
-
-Note the library only supports UTF-8. When you store strings with different encodings in the library, calling [`dump()`](https://nlohmann.github.io/json/api/basic_json/dump/) may throw an exception unless `json::error_handler_t::replace` or `json::error_handler_t::ignore` are used as error handlers.
-
-#### To/from streams (e.g. files, string streams)
-
-You can also use streams to serialize and deserialize:
-
-```cpp
-// deserialize from standard input
-json j;
-std::cin >> j;
-
-// serialize to standard output
-std::cout << j;
-
-// the setw manipulator was overloaded to set the indentation for pretty printing
-std::cout << std::setw(4) << j << std::endl;
-```
-
-These operators work for any subclasses of `std::istream` or `std::ostream`. Here is the same example with files:
-
-```cpp
-// read a JSON file
-std::ifstream i("file.json");
-json j;
-i >> j;
-
-// write prettified JSON to another file
-std::ofstream o("pretty.json");
-o << std::setw(4) << j << std::endl;
-```
-
-Please note that setting the exception bit for `failbit` is inappropriate for this use case. It will result in program termination due to the `noexcept` specifier in use.
-
-#### Read from iterator range
-
-You can also parse JSON from an iterator range; that is, from any container accessible by iterators whose `value_type` is an integral type of 1, 2 or 4 bytes, which will be interpreted as UTF-8, UTF-16 and UTF-32 respectively. For instance, a `std::vector<std::uint8_t>`, or a `std::list<std::uint16_t>`:
-
-```cpp
-std::vector<std::uint8_t> v = {'t', 'r', 'u', 'e'};
-json j = json::parse(v.begin(), v.end());
-```
-
-You may leave the iterators for the range [begin, end):
-
-```cpp
-std::vector<std::uint8_t> v = {'t', 'r', 'u', 'e'};
-json j = json::parse(v);
-```
-
-#### Custom data source
-
-Since the parse function accepts arbitrary iterator ranges, you can provide your own data sources by implementing the `LegacyInputIterator` concept.
-
-```cpp
-struct MyContainer {
-  void advance();
-  const char& get_current();
-};
-
-struct MyIterator {
-    using difference_type = std::ptrdiff_t;
-    using value_type = char;
-    using pointer = const char*;
-    using reference = const char&;
-    using iterator_category = std::input_iterator_tag;
-
-    MyIterator& operator++() {
-        MyContainer.advance();
-        return *this;
-    }
-
-    bool operator!=(const MyIterator& rhs) const {
-        return rhs.target != target;
-    }
-
-    reference operator*() const {
-        return target.get_current();
-    }
-
-    MyContainer* target = nullptr;
-};
-
-MyIterator begin(MyContainer& tgt) {
-    return MyIterator{&tgt};
-}
-
-MyIterator end(const MyContainer&) {
-    return {};
-}
-
-void foo() {
-    MyContainer c;
-    json j = json::parse(c);
-}
-```
-
-#### SAX interface
-
-The library uses a SAX-like interface with the following functions:
-
-```cpp
-// called when null is parsed
-bool null();
-
-// called when a boolean is parsed; value is passed
-bool boolean(bool val);
-
-// called when a signed or unsigned integer number is parsed; value is passed
-bool number_integer(number_integer_t val);
-bool number_unsigned(number_unsigned_t val);
-
-// called when a floating-point number is parsed; value and original string is passed
-bool number_float(number_float_t val, const string_t& s);
-
-// called when a string is parsed; value is passed and can be safely moved away
-bool string(string_t& val);
-// called when a binary value is parsed; value is passed and can be safely moved away
-bool binary(binary_t& val);
-
-// called when an object or array begins or ends, resp. The number of elements is passed (or -1 if not known)
-bool start_object(std::size_t elements);
-bool end_object();
-bool start_array(std::size_t elements);
-bool end_array();
-// called when an object key is parsed; value is passed and can be safely moved away
-bool key(string_t& val);
-
-// called when a parse error occurs; byte position, the last token, and an exception is passed
-bool parse_error(std::size_t position, const std::string& last_token, const detail::exception& ex);
-```
-
-The return value of each function determines whether parsing should proceed.
-
-To implement your own SAX handler, proceed as follows:
-
-1. Implement the SAX interface in a class. You can use class `nlohmann::json_sax<json>` as base class, but you can also use any class where the functions described above are implemented and public.
-2. Create an object of your SAX interface class, e.g. `my_sax`.
-3. Call `bool json::sax_parse(input, &my_sax)`; where the first parameter can be any input like a string or an input stream and the second parameter is a pointer to your SAX interface.
-
-Note the `sax_parse` function only returns a `bool` indicating the result of the last executed SAX event. It does not return a  `json` value - it is up to you to decide what to do with the SAX events. Furthermore, no exceptions are thrown in case of a parse error - it is up to you what to do with the exception object passed to your `parse_error` implementation. Internally, the SAX interface is used for the DOM parser (class `json_sax_dom_parser`) as well as the acceptor (`json_sax_acceptor`), see file [`json_sax.hpp`](https://github.com/nlohmann/json/blob/develop/include/nlohmann/detail/input/json_sax.hpp).
-
-### STL-like access
-
-We designed the JSON class to behave just like an STL container. In fact, it satisfies the [**ReversibleContainer**](https://en.cppreference.com/w/cpp/named_req/ReversibleContainer) requirement.
-
-```cpp
-// create an array using push_back
-json j;
-j.push_back("foo");
-j.push_back(1);
-j.push_back(true);
-
-// also use emplace_back
-j.emplace_back(1.78);
-
-// iterate the array
-for (json::iterator it = j.begin(); it != j.end(); ++it) {
-  std::cout << *it << '\n';
-}
-
-// range-based for
-for (auto& element : j) {
-  std::cout << element << '\n';
-}
-
-// getter/setter
-const auto tmp = j[0].get<std::string>();
-j[1] = 42;
-bool foo = j.at(2);
-
-// comparison
-j == R"(["foo", 1, true, 1.78])"_json;  // true
-
-// other stuff
-j.size();     // 4 entries
-j.empty();    // false
-j.type();     // json::value_t::array
-j.clear();    // the array is empty again
-
-// convenience type checkers
-j.is_null();
-j.is_boolean();
-j.is_number();
-j.is_object();
-j.is_array();
-j.is_string();
-
-// create an object
-json o;
-o["foo"] = 23;
-o["bar"] = false;
-o["baz"] = 3.141;
-
-// also use emplace
-o.emplace("weather", "sunny");
-
-// special iterator member functions for objects
-for (json::iterator it = o.begin(); it != o.end(); ++it) {
-  std::cout << it.key() << " : " << it.value() << "\n";
-}
-
-// the same code as range for
-for (auto& el : o.items()) {
-  std::cout << el.key() << " : " << el.value() << "\n";
-}
-
-// even easier with structured bindings (C++17)
-for (auto& [key, value] : o.items()) {
-  std::cout << key << " : " << value << "\n";
-}
-
-// find an entry
-if (o.contains("foo")) {
-  // there is an entry with key "foo"
-}
-
-// or via find and an iterator
-if (o.find("foo") != o.end()) {
-  // there is an entry with key "foo"
-}
-
-// or simpler using count()
-int foo_present = o.count("foo"); // 1
-int fob_present = o.count("fob"); // 0
-
-// delete an entry
-o.erase("foo");
-```
-
-
-### Conversion from STL containers
-
-Any sequence container (`std::array`, `std::vector`, `std::deque`, `std::forward_list`, `std::list`) whose values can be used to construct JSON values (e.g., integers, floating point numbers, Booleans, string types, or again STL containers described in this section) can be used to create a JSON array. The same holds for similar associative containers (`std::set`, `std::multiset`, `std::unordered_set`, `std::unordered_multiset`), but in these cases the order of the elements of the array depends on how the elements are ordered in the respective STL container.
-
-```cpp
-std::vector<int> c_vector {1, 2, 3, 4};
-json j_vec(c_vector);
-// [1, 2, 3, 4]
-
-std::deque<double> c_deque {1.2, 2.3, 3.4, 5.6};
-json j_deque(c_deque);
-// [1.2, 2.3, 3.4, 5.6]
-
-std::list<bool> c_list {true, true, false, true};
-json j_list(c_list);
-// [true, true, false, true]
-
-std::forward_list<int64_t> c_flist {12345678909876, 23456789098765, 34567890987654, 45678909876543};
-json j_flist(c_flist);
-// [12345678909876, 23456789098765, 34567890987654, 45678909876543]
-
-std::array<unsigned long, 4> c_array {{1, 2, 3, 4}};
-json j_array(c_array);
-// [1, 2, 3, 4]
-
-std::set<std::string> c_set {"one", "two", "three", "four", "one"};
-json j_set(c_set); // only one entry for "one" is used
-// ["four", "one", "three", "two"]
-
-std::unordered_set<std::string> c_uset {"one", "two", "three", "four", "one"};
-json j_uset(c_uset); // only one entry for "one" is used
-// maybe ["two", "three", "four", "one"]
-
-std::multiset<std::string> c_mset {"one", "two", "one", "four"};
-json j_mset(c_mset); // both entries for "one" are used
-// maybe ["one", "two", "one", "four"]
-
-std::unordered_multiset<std::string> c_umset {"one", "two", "one", "four"};
-json j_umset(c_umset); // both entries for "one" are used
-// maybe ["one", "two", "one", "four"]
-```
-
-Likewise, any associative key-value containers (`std::map`, `std::multimap`, `std::unordered_map`, `std::unordered_multimap`) whose keys can construct an `std::string` and whose values can be used to construct JSON values (see examples above) can be used to create a JSON object. Note that in case of multimaps only one key is used in the JSON object and the value depends on the internal order of the STL container.
-
-```cpp
-std::map<std::string, int> c_map { {"one", 1}, {"two", 2}, {"three", 3} };
-json j_map(c_map);
-// {"one": 1, "three": 3, "two": 2 }
-
-std::unordered_map<const char*, double> c_umap { {"one", 1.2}, {"two", 2.3}, {"three", 3.4} };
-json j_umap(c_umap);
-// {"one": 1.2, "two": 2.3, "three": 3.4}
-
-std::multimap<std::string, bool> c_mmap { {"one", true}, {"two", true}, {"three", false}, {"three", true} };
-json j_mmap(c_mmap); // only one entry for key "three" is used
-// maybe {"one": true, "two": true, "three": true}
-
-std::unordered_multimap<std::string, bool> c_ummap { {"one", true}, {"two", true}, {"three", false}, {"three", true} };
-json j_ummap(c_ummap); // only one entry for key "three" is used
-// maybe {"one": true, "two": true, "three": true}
-```
-
-### JSON Pointer and JSON Patch
-
-The library supports **JSON Pointer** ([RFC 6901](https://tools.ietf.org/html/rfc6901)) as alternative means to address structured values. On top of this, **JSON Patch** ([RFC 6902](https://tools.ietf.org/html/rfc6902)) allows describing differences between two JSON values - effectively allowing patch and diff operations known from Unix.
-
-```cpp
-// a JSON value
-json j_original = R"({
-  "baz": ["one", "two", "three"],
-  "foo": "bar"
-})"_json;
-
-// access members with a JSON pointer (RFC 6901)
-j_original["/baz/1"_json_pointer];
-// "two"
-
-// a JSON patch (RFC 6902)
-json j_patch = R"([
-  { "op": "replace", "path": "/baz", "value": "boo" },
-  { "op": "add", "path": "/hello", "value": ["world"] },
-  { "op": "remove", "path": "/foo"}
-])"_json;
-
-// apply the patch
-json j_result = j_original.patch(j_patch);
-// {
-//    "baz": "boo",
-//    "hello": ["world"]
-// }
-
-// calculate a JSON patch from two JSON values
-json::diff(j_result, j_original);
-// [
-//   { "op":" replace", "path": "/baz", "value": ["one", "two", "three"] },
-//   { "op": "remove","path": "/hello" },
-//   { "op": "add", "path": "/foo", "value": "bar" }
-// ]
-```
-
-### JSON Merge Patch
-
-The library supports **JSON Merge Patch** ([RFC 7386](https://tools.ietf.org/html/rfc7386)) as a patch format. Instead of using JSON Pointer (see above) to specify values to be manipulated, it describes the changes using a syntax that closely mimics the document being modified.
-
-```cpp
-// a JSON value
-json j_document = R"({
-  "a": "b",
-  "c": {
-    "d": "e",
-    "f": "g"
-  }
-})"_json;
-
-// a patch
-json j_patch = R"({
-  "a":"z",
-  "c": {
-    "f": null
-  }
-})"_json;
-
-// apply the patch
-j_document.merge_patch(j_patch);
-// {
-//  "a": "z",
-//  "c": {
-//    "d": "e"
-//  }
-// }
-```
-
-### Implicit conversions
-
-Supported types can be implicitly converted to JSON values.
-
-It is recommended to **NOT USE** implicit conversions **FROM** a JSON value.
-You can find more details about this recommendation [here](https://www.github.com/nlohmann/json/issues/958).
-You can switch off implicit conversions by defining `JSON_USE_IMPLICIT_CONVERSIONS` to `0` before including the `json.hpp` header. When using CMake, you can also achieve this by setting the option `JSON_ImplicitConversions` to `OFF`.
-
-```cpp
-// strings
-std::string s1 = "Hello, world!";
-json js = s1;
-auto s2 = js.get<std::string>();
-// NOT RECOMMENDED
-std::string s3 = js;
-std::string s4;
-s4 = js;
-
-// Booleans
-bool b1 = true;
-json jb = b1;
-auto b2 = jb.get<bool>();
-// NOT RECOMMENDED
-bool b3 = jb;
-bool b4;
-b4 = jb;
-
-// numbers
-int i = 42;
-json jn = i;
-auto f = jn.get<double>();
-// NOT RECOMMENDED
-double f2 = jb;
-double f3;
-f3 = jb;
-
-// etc.
-```
-
-Note that `char` types are not automatically converted to JSON strings, but to integer numbers. A conversion to a string must be specified explicitly:
-
-```cpp
-char ch = 'A';                       // ASCII value 65
-json j_default = ch;                 // stores integer number 65
-json j_string = std::string(1, ch);  // stores string "A"
-```
-
-### Arbitrary types conversions
-
-Every type can be serialized in JSON, not just STL containers and scalar types. Usually, you would do something along those lines:
-
-```cpp
-namespace ns {
-    // a simple struct to model a person
-    struct person {
-        std::string name;
-        std::string address;
-        int age;
-    };
-}
-
-ns::person p = {"Ned Flanders", "744 Evergreen Terrace", 60};
-
-// convert to JSON: copy each value into the JSON object
-json j;
-j["name"] = p.name;
-j["address"] = p.address;
-j["age"] = p.age;
-
-// ...
-
-// convert from JSON: copy each value from the JSON object
-ns::person p {
-    j["name"].get<std::string>(),
-    j["address"].get<std::string>(),
-    j["age"].get<int>()
-};
-```
-
-It works, but that's quite a lot of boilerplate... Fortunately, there's a better way:
-
-```cpp
-// create a person
-ns::person p {"Ned Flanders", "744 Evergreen Terrace", 60};
-
-// conversion: person -> json
-json j = p;
-
-std::cout << j << std::endl;
-// {"address":"744 Evergreen Terrace","age":60,"name":"Ned Flanders"}
-
-// conversion: json -> person
-auto p2 = j.get<ns::person>();
-
-// that's it
-assert(p == p2);
-```
-
-#### Basic usage
-
-To make this work with one of your types, you only need to provide two functions:
-
-```cpp
-using json = nlohmann::json;
-
-namespace ns {
-    void to_json(json& j, const person& p) {
-        j = json{{"name", p.name}, {"address", p.address}, {"age", p.age}};
-    }
-
-    void from_json(const json& j, person& p) {
-        j.at("name").get_to(p.name);
-        j.at("address").get_to(p.address);
-        j.at("age").get_to(p.age);
-    }
-} // namespace ns
-```
-
-That's all! When calling the `json` constructor with your type, your custom `to_json` method will be automatically called.
-Likewise, when calling `get<your_type>()` or `get_to(your_type&)`, the `from_json` method will be called.
-
-Some important things:
-
-* Those methods **MUST** be in your type's namespace (which can be the global namespace), or the library will not be able to locate them (in this example, they are in namespace `ns`, where `person` is defined).
-* Those methods **MUST** be available (e.g., proper headers must be included) everywhere you use these conversions. Look at [issue 1108](https://github.com/nlohmann/json/issues/1108) for errors that may occur otherwise.
-* When using `get<your_type>()`, `your_type` **MUST** be [DefaultConstructible](https://en.cppreference.com/w/cpp/named_req/DefaultConstructible). (There is a way to bypass this requirement described later.)
-* In function `from_json`, use function [`at()`](https://nlohmann.github.io/json/api/basic_json/at/) to access the object values rather than `operator[]`. In case a key does not exist, `at` throws an exception that you can handle, whereas `operator[]` exhibits undefined behavior.
-* You do not need to add serializers or deserializers for STL types like `std::vector`: the library already implements these.
-
-#### Simplify your life with macros
-
-If you just want to serialize/deserialize some structs, the `to_json`/`from_json` functions can be a lot of boilerplate.
-
-There are two macros to make your life easier as long as you (1) want to use a JSON object as serialization and (2) want to use the member variable names as object keys in that object:
-
-- `NLOHMANN_DEFINE_TYPE_NON_INTRUSIVE(name, member1, member2, ...)` is to be defined inside the namespace of the class/struct to create code for.
-- `NLOHMANN_DEFINE_TYPE_INTRUSIVE(name, member1, member2, ...)` is to be defined inside the class/struct to create code for. This macro can also access private members.
-
-In both macros, the first parameter is the name of the class/struct, and all remaining parameters name the members.
-
-##### Examples
-
-The `to_json`/`from_json` functions for the `person` struct above can be created with:
-
-```cpp
-namespace ns {
-    NLOHMANN_DEFINE_TYPE_NON_INTRUSIVE(person, name, address, age)
-}
-```
-
-Here is an example with private members, where `NLOHMANN_DEFINE_TYPE_INTRUSIVE` is needed:
-
-```cpp
-namespace ns {
-    class address {
-      private:
-        std::string street;
-        int housenumber;
-        int postcode;
-
-      public:
-        NLOHMANN_DEFINE_TYPE_INTRUSIVE(address, street, housenumber, postcode)
-    };
-}
-```
-
-#### How do I convert third-party types?
-
-This requires a bit more advanced technique. But first, let's see how this conversion mechanism works:
-
-The library uses **JSON Serializers** to convert types to json.
-The default serializer for `nlohmann::json` is `nlohmann::adl_serializer` (ADL means [Argument-Dependent Lookup](https://en.cppreference.com/w/cpp/language/adl)).
-
-It is implemented like this (simplified):
-
-```cpp
-template <typename T>
-struct adl_serializer {
-    static void to_json(json& j, const T& value) {
-        // calls the "to_json" method in T's namespace
-    }
-
-    static void from_json(const json& j, T& value) {
-        // same thing, but with the "from_json" method
-    }
-};
-```
-
-This serializer works fine when you have control over the type's namespace. However, what about `boost::optional` or `std::filesystem::path` (C++17)? Hijacking the `boost` namespace is pretty bad, and it's illegal to add something other than template specializations to `std`...
-
-To solve this, you need to add a specialization of `adl_serializer` to the `nlohmann` namespace, here's an example:
-
-```cpp
-// partial specialization (full specialization works too)
-namespace nlohmann {
-    template <typename T>
-    struct adl_serializer<boost::optional<T>> {
-        static void to_json(json& j, const boost::optional<T>& opt) {
-            if (opt == boost::none) {
-                j = nullptr;
-            } else {
-              j = *opt; // this will call adl_serializer<T>::to_json which will
-                        // find the free function to_json in T's namespace!
-            }
-        }
-
-        static void from_json(const json& j, boost::optional<T>& opt) {
-            if (j.is_null()) {
-                opt = boost::none;
-            } else {
-                opt = j.get<T>(); // same as above, but with
-                                  // adl_serializer<T>::from_json
-            }
-        }
-    };
-}
-```
-
-#### How can I use `get()` for non-default constructible/non-copyable types?
-
-There is a way, if your type is [MoveConstructible](https://en.cppreference.com/w/cpp/named_req/MoveConstructible). You will need to specialize the `adl_serializer` as well, but with a special `from_json` overload:
-
-```cpp
-struct move_only_type {
-    move_only_type() = delete;
-    move_only_type(int ii): i(ii) {}
-    move_only_type(const move_only_type&) = delete;
-    move_only_type(move_only_type&&) = default;
-
-    int i;
-};
-
-namespace nlohmann {
-    template <>
-    struct adl_serializer<move_only_type> {
-        // note: the return type is no longer 'void', and the method only takes
-        // one argument
-        static move_only_type from_json(const json& j) {
-            return {j.get<int>()};
-        }
-
-        // Here's the catch! You must provide a to_json method! Otherwise, you
-        // will not be able to convert move_only_type to json, since you fully
-        // specialized adl_serializer on that type
-        static void to_json(json& j, move_only_type t) {
-            j = t.i;
-        }
-    };
-}
-```
-
-#### Can I write my own serializer? (Advanced use)
-
-Yes. You might want to take a look at [`unit-udt.cpp`](https://github.com/nlohmann/json/blob/develop/test/src/unit-udt.cpp) in the test suite, to see a few examples.
-
-If you write your own serializer, you'll need to do a few things:
-
-- use a different `basic_json` alias than `nlohmann::json` (the last template parameter of `basic_json` is the `JSONSerializer`)
-- use your `basic_json` alias (or a template parameter) in all your `to_json`/`from_json` methods
-- use `nlohmann::to_json` and `nlohmann::from_json` when you need ADL
-
-Here is an example, without simplifications, that only accepts types with a size <= 32, and uses ADL.
-
-```cpp
-// You should use void as a second template argument
-// if you don't need compile-time checks on T
-template<typename T, typename SFINAE = typename std::enable_if<sizeof(T) <= 32>::type>
-struct less_than_32_serializer {
-    template <typename BasicJsonType>
-    static void to_json(BasicJsonType& j, T value) {
-        // we want to use ADL, and call the correct to_json overload
-        using nlohmann::to_json; // this method is called by adl_serializer,
-                                 // this is where the magic happens
-        to_json(j, value);
-    }
-
-    template <typename BasicJsonType>
-    static void from_json(const BasicJsonType& j, T& value) {
-        // same thing here
-        using nlohmann::from_json;
-        from_json(j, value);
-    }
-};
-```
-
-Be **very** careful when reimplementing your serializer, you can stack overflow if you don't pay attention:
-
-```cpp
-template <typename T, void>
-struct bad_serializer
-{
-    template <typename BasicJsonType>
-    static void to_json(BasicJsonType& j, const T& value) {
-      // this calls BasicJsonType::json_serializer<T>::to_json(j, value);
-      // if BasicJsonType::json_serializer == bad_serializer ... oops!
-      j = value;
-    }
-
-    template <typename BasicJsonType>
-    static void to_json(const BasicJsonType& j, T& value) {
-      // this calls BasicJsonType::json_serializer<T>::from_json(j, value);
-      // if BasicJsonType::json_serializer == bad_serializer ... oops!
-      value = j.template get<T>(); // oops!
-    }
-};
-```
-
-### Specializing enum conversion
-
-By default, enum values are serialized to JSON as integers. In some cases this could result in undesired behavior. If an enum is modified or re-ordered after data has been serialized to JSON, the later de-serialized JSON data may be undefined or a different enum value than was originally intended.
-
-It is possible to more precisely specify how a given enum is mapped to and from JSON as shown below:
-
-```cpp
-// example enum type declaration
-enum TaskState {
-    TS_STOPPED,
-    TS_RUNNING,
-    TS_COMPLETED,
-    TS_INVALID=-1,
-};
-
-// map TaskState values to JSON as strings
-NLOHMANN_JSON_SERIALIZE_ENUM( TaskState, {
-    {TS_INVALID, nullptr},
-    {TS_STOPPED, "stopped"},
-    {TS_RUNNING, "running"},
-    {TS_COMPLETED, "completed"},
-})
-```
-
-The `NLOHMANN_JSON_SERIALIZE_ENUM()` macro declares a set of `to_json()` / `from_json()` functions for type `TaskState` while avoiding repetition and boilerplate serialization code.
-
-**Usage:**
-
-```cpp
-// enum to JSON as string
-json j = TS_STOPPED;
-assert(j == "stopped");
-
-// json string to enum
-json j3 = "running";
-assert(j3.get<TaskState>() == TS_RUNNING);
-
-// undefined json value to enum (where the first map entry above is the default)
-json jPi = 3.14;
-assert(jPi.get<TaskState>() == TS_INVALID );
-```
-
-Just as in [Arbitrary Type Conversions](#arbitrary-types-conversions) above,
-- `NLOHMANN_JSON_SERIALIZE_ENUM()` MUST be declared in your enum type's namespace (which can be the global namespace), or the library will not be able to locate it, and it will default to integer serialization.
-- It MUST be available (e.g., proper headers must be included) everywhere you use the conversions.
-
-Other Important points:
-- When using `get<ENUM_TYPE>()`, undefined JSON values will default to the first pair specified in your map. Select this default pair carefully.
-- If an enum or JSON value is specified more than once in your map, the first matching occurrence from the top of the map will be returned when converting to or from JSON.
-
-### Binary formats (BSON, CBOR, MessagePack, and UBJSON)
-
-Though JSON is a ubiquitous data format, it is not a very compact format suitable for data exchange, for instance over a network. Hence, the library supports [BSON](https://bsonspec.org) (Binary JSON), [CBOR](https://cbor.io) (Concise Binary Object Representation), [MessagePack](https://msgpack.org), and [UBJSON](https://ubjson.org) (Universal Binary JSON Specification) to efficiently encode JSON values to byte vectors and to decode such vectors.
-
-```cpp
-// create a JSON value
-json j = R"({"compact": true, "schema": 0})"_json;
-
-// serialize to BSON
-std::vector<std::uint8_t> v_bson = json::to_bson(j);
-
-// 0x1B, 0x00, 0x00, 0x00, 0x08, 0x63, 0x6F, 0x6D, 0x70, 0x61, 0x63, 0x74, 0x00, 0x01, 0x10, 0x73, 0x63, 0x68, 0x65, 0x6D, 0x61, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00
-
-// roundtrip
-json j_from_bson = json::from_bson(v_bson);
-
-// serialize to CBOR
-std::vector<std::uint8_t> v_cbor = json::to_cbor(j);
-
-// 0xA2, 0x67, 0x63, 0x6F, 0x6D, 0x70, 0x61, 0x63, 0x74, 0xF5, 0x66, 0x73, 0x63, 0x68, 0x65, 0x6D, 0x61, 0x00
-
-// roundtrip
-json j_from_cbor = json::from_cbor(v_cbor);
-
-// serialize to MessagePack
-std::vector<std::uint8_t> v_msgpack = json::to_msgpack(j);
-
-// 0x82, 0xA7, 0x63, 0x6F, 0x6D, 0x70, 0x61, 0x63, 0x74, 0xC3, 0xA6, 0x73, 0x63, 0x68, 0x65, 0x6D, 0x61, 0x00
-
-// roundtrip
-json j_from_msgpack = json::from_msgpack(v_msgpack);
-
-// serialize to UBJSON
-std::vector<std::uint8_t> v_ubjson = json::to_ubjson(j);
-
-// 0x7B, 0x69, 0x07, 0x63, 0x6F, 0x6D, 0x70, 0x61, 0x63, 0x74, 0x54, 0x69, 0x06, 0x73, 0x63, 0x68, 0x65, 0x6D, 0x61, 0x69, 0x00, 0x7D
-
-// roundtrip
-json j_from_ubjson = json::from_ubjson(v_ubjson);
-```
-
-The library also supports binary types from BSON, CBOR (byte strings), and MessagePack (bin, ext, fixext). They are stored by default as `std::vector<std::uint8_t>` to be processed outside the library.
-
-```cpp
-// CBOR byte string with payload 0xCAFE
-std::vector<std::uint8_t> v = {0x42, 0xCA, 0xFE};
-
-// read value
-json j = json::from_cbor(v);
-
-// the JSON value has type binary
-j.is_binary(); // true
-
-// get reference to stored binary value
-auto& binary = j.get_binary();
-
-// the binary value has no subtype (CBOR has no binary subtypes)
-binary.has_subtype(); // false
-
-// access std::vector<std::uint8_t> member functions
-binary.size(); // 2
-binary[0]; // 0xCA
-binary[1]; // 0xFE
-
-// set subtype to 0x10
-binary.set_subtype(0x10);
-
-// serialize to MessagePack
-auto cbor = json::to_msgpack(j); // 0xD5 (fixext2), 0x10, 0xCA, 0xFE
-```

-## Supported compilers
-
-Though it's 2022 already, the support for C++11 is still a bit sparse. Currently, the following compilers are known to work:
-
-- GCC 4.8 - 11.0 (and possibly later)
-- Clang 3.4 - 13.0 (and possibly later)
-- Apple Clang 9.1 - 13.0 (and possibly later)
-- Intel C++ Compiler 17.0.2 (and possibly later)
-- Nvidia CUDA Compiler 11.0.221 (and possibly later)
-- Microsoft Visual C++ 2015 / Build Tools 14.0.25123.0 (and possibly later)
-- Microsoft Visual C++ 2017 / Build Tools 15.5.180.51428 (and possibly later)
-- Microsoft Visual C++ 2019 / Build Tools 16.3.1+1def00d3d (and possibly later)
-
-I would be happy to learn about other compilers/versions.
-
-Please note:
-
-- GCC 4.8 has a bug [57824](https://gcc.gnu.org/bugzilla/show_bug.cgi?id=57824)): multiline raw strings cannot be the arguments to macros. Don't use multiline raw strings directly in macros with this compiler.
-- Android defaults to using very old compilers and C++ libraries. To fix this, add the following to your `Application.mk`. This will switch to the LLVM C++ library, the Clang compiler, and enable C++11 and other features disabled by default.
-
-    ```
-    APP_STL := c++_shared
-    NDK_TOOLCHAIN_VERSION := clang3.6
-    APP_CPPFLAGS += -frtti -fexceptions
-    ```
-
-    The code compiles successfully with [Android NDK](https://developer.android.com/ndk/index.html?hl=ml), Revision 9 - 11 (and possibly later) and [CrystaX's Android NDK](https://www.crystax.net/en/android/ndk) version 10.
-
-- For GCC running on MinGW or Android SDK, the error `'to_string' is not a member of 'std'` (or similarly, for `strtod` or `strtof`) may occur. Note this is not an issue with the code,  but rather with the compiler itself. On Android, see above to build with a newer environment.  For MinGW, please refer to [this site](https://tehsausage.com/mingw-to-string) and [this discussion](https://github.com/nlohmann/json/issues/136) for information on how to fix this bug. For Android NDK using `APP_STL := gnustl_static`, please refer to [this discussion](https://github.com/nlohmann/json/issues/219).
-
-- Unsupported versions of GCC and Clang are rejected by `#error` directives. This can be switched off by defining `JSON_SKIP_UNSUPPORTED_COMPILER_CHECK`. Note that you can expect no support in this case.
-
-The following compilers are currently used in continuous integration at [AppVeyor](https://ci.appveyor.com/project/nlohmann/json), [Drone CI](https://cloud.drone.io/nlohmann/json), and [GitHub Actions](https://github.com/nlohmann/json/actions):

-## Integration
-
-[`json.hpp`](https://github.com/nlohmann/json/blob/develop/single_include/nlohmann/json.hpp) is the single required file in `single_include/nlohmann` or [released here](https://github.com/nlohmann/json/releases). You need to add
-
-```cpp
-#include <nlohmann/json.hpp>
-
-// for convenience
-using json = nlohmann::json;
-```
-
-to the files you want to process JSON and set the necessary switches to enable C++11 (e.g., `-std=c++11` for GCC and Clang).
-
-You can further use file [`include/nlohmann/json_fwd.hpp`](https://github.com/nlohmann/json/blob/develop/include/nlohmann/json_fwd.hpp) for forward-declarations. The installation of json_fwd.hpp (as part of cmake's install step), can be achieved by setting `-DJSON_MultipleHeaders=ON`.
-
-### CMake
-
-You can also use the `nlohmann_json::nlohmann_json` interface target in CMake.  This target populates the appropriate usage requirements for `INTERFACE_INCLUDE_DIRECTORIES` to point to the appropriate include directories and `INTERFACE_COMPILE_FEATURES` for the necessary C++11 flags.
-
-#### External
-
-To use this library from a CMake project, you can locate it directly with `find_package()` and use the namespaced imported target from the generated package configuration:
-
-```cmake
-# CMakeLists.txt
-find_package(nlohmann_json 3.2.0 REQUIRED)
-...
-add_library(foo ...)
-...
-target_link_libraries(foo PRIVATE nlohmann_json::nlohmann_json)
-```
-
-The package configuration file, `nlohmann_jsonConfig.cmake`, can be used either from an install tree or directly out of the build tree.
-
-#### Embedded
-
-To embed the library directly into an existing CMake project, place the entire source tree in a subdirectory and call `add_subdirectory()` in your `CMakeLists.txt` file:
-
-```cmake
-# Typically you don't care so much for a third party library's tests to be
-# run from your own project's code.
-set(JSON_BuildTests OFF CACHE INTERNAL "")
-
-# If you only include this third party in PRIVATE source files, you do not
-# need to install it when your main project gets installed.
-# set(JSON_Install OFF CACHE INTERNAL "")
-
-# Don't use include(nlohmann_json/CMakeLists.txt) since that carries with it
-# unintended consequences that will break the build.  It's generally
-# discouraged (although not necessarily well documented as such) to use
-# include(...) for pulling in other CMake projects anyways.
-add_subdirectory(nlohmann_json)
-...
-add_library(foo ...)
-...
-target_link_libraries(foo PRIVATE nlohmann_json::nlohmann_json)
-```
-
-##### Embedded (FetchContent)
-
-Since CMake v3.11,
-[FetchContent](https://cmake.org/cmake/help/v3.11/module/FetchContent.html) can
-be used to automatically download the repository as a dependency at configure time.
-
-Example:
-```cmake
-include(FetchContent)
-
-FetchContent_Declare(json
-  GIT_REPOSITORY https://github.com/nlohmann/json.git
-  GIT_TAG v3.7.3)
-
-FetchContent_GetProperties(json)
-if(NOT json_POPULATED)
-  FetchContent_Populate(json)
-  add_subdirectory(${json_SOURCE_DIR} ${json_BINARY_DIR} EXCLUDE_FROM_ALL)
-endif()
-
-target_link_libraries(foo PRIVATE nlohmann_json::nlohmann_json)
-```
-
-**Note**: The repository https://github.com/nlohmann/json download size is huge.
-It contains all the dataset used for the benchmarks. You might want to depend on
-a smaller repository. For instance, you might want to replace the URL above by
-https://github.com/ArthurSonzogni/nlohmann_json_cmake_fetchcontent
-
-#### Supporting Both
-
-To allow your project to support either an externally supplied or an embedded JSON library, you can use a pattern akin to the following:
-
-``` cmake
-# Top level CMakeLists.txt
-project(FOO)
-...
-option(FOO_USE_EXTERNAL_JSON "Use an external JSON library" OFF)
-...
-add_subdirectory(thirdparty)
-...
-add_library(foo ...)
-...
-# Note that the namespaced target will always be available regardless of the
-# import method
-target_link_libraries(foo PRIVATE nlohmann_json::nlohmann_json)
-```
-```cmake
-# thirdparty/CMakeLists.txt
-...
-if(FOO_USE_EXTERNAL_JSON)
-  find_package(nlohmann_json 3.2.0 REQUIRED)
-else()
-  set(JSON_BuildTests OFF CACHE INTERNAL "")
-  add_subdirectory(nlohmann_json)
-endif()
-...
-```
-
-`thirdparty/nlohmann_json` is then a complete copy of this source tree.
-
-### Package Managers
-
-:beer: If you are using OS X and [Homebrew](https://brew.sh), just type `brew install nlohmann-json` and you're set. If you want the bleeding edge rather than the latest release, use `brew install nlohmann-json --HEAD`. See [nlohmann-json](https://formulae.brew.sh/formula/nlohmann-json) for more information.
-
-If you are using the [Meson Build System](https://mesonbuild.com), add this source tree as a [meson subproject](https://mesonbuild.com/Subprojects.html#using-a-subproject). You may also use the `include.zip` published in this project's [Releases](https://github.com/nlohmann/json/releases) to reduce the size of the vendored source tree. Alternatively, you can get a wrap file by downloading it from [Meson WrapDB](https://wrapdb.mesonbuild.com/nlohmann_json), or simply use `meson wrap install nlohmann_json`. Please see the meson project for any issues regarding the packaging.
-
-The provided `meson.build` can also be used as an alternative to cmake for installing `nlohmann_json` system-wide in which case a pkg-config file is installed. To use it, simply have your build system require the `nlohmann_json` pkg-config dependency. In Meson, it is preferred to use the [`dependency()`](https://mesonbuild.com/Reference-manual.html#dependency) object with a subproject fallback, rather than using the subproject directly.
-
-If you are using [Conan](https://www.conan.io/) to manage your dependencies, merely add [`nlohmann_json/x.y.z`](https://conan.io/center/nlohmann_json) to your `conanfile`'s requires, where `x.y.z` is the release version you want to use. Please file issues [here](https://github.com/conan-io/conan-center-index/issues) if you experience problems with the packages.
-
-If you are using [Spack](https://www.spack.io/) to manage your dependencies, you can use the [`nlohmann-json` package](https://spack.readthedocs.io/en/latest/package_list.html#nlohmann-json). Please see the [spack project](https://github.com/spack/spack) for any issues regarding the packaging.

-
-If you are using [vcpkg](https://github.com/Microsoft/vcpkg/) on your project for external dependencies, then you can install the [nlohmann-json package](https://github.com/Microsoft/vcpkg/tree/master/ports/nlohmann-json) with `vcpkg install nlohmann-json` and follow the then displayed descriptions. Please see the vcpkg project for any issues regarding the packaging.
-
-If you are using [cget](https://cget.readthedocs.io/en/latest/), you can install the latest development version with `cget install nlohmann/json`. A specific version can be installed with `cget install nlohmann/json@v3.1.0`. Also, the multiple header version can be installed by adding the `-DJSON_MultipleHeaders=ON` flag (i.e., `cget install nlohmann/json -DJSON_MultipleHeaders=ON`).
-
-If you are using [CocoaPods](https://cocoapods.org), you can use the library by adding pod `"nlohmann_json", '~>3.1.2'` to your podfile (see [an example](https://bitbucket.org/benman/nlohmann_json-cocoapod/src/master/)). Please file issues [here](https://bitbucket.org/benman/nlohmann_json-cocoapod/issues?status=new&status=open).
-
-If you are using [NuGet](https://www.nuget.org), you can use the package [nlohmann.json](https://www.nuget.org/packages/nlohmann.json/). Please check [this extensive description](https://github.com/nlohmann/json/issues/1132#issuecomment-452250255) on how to use the package. Please file issues [here](https://github.com/hnkb/nlohmann-json-nuget/issues).
-
-If you are using [conda](https://conda.io/), you can use the package [nlohmann_json](https://github.com/conda-forge/nlohmann_json-feedstock) from [conda-forge](https://conda-forge.org) executing `conda install -c conda-forge nlohmann_json`. Please file issues [here](https://github.com/conda-forge/nlohmann_json-feedstock/issues).
-
-If you are using [MSYS2](https://www.msys2.org/), you can use the [mingw-w64-nlohmann-json](https://packages.msys2.org/base/mingw-w64-nlohmann-json) package, just type `pacman -S mingw-w64-i686-nlohmann-json` or `pacman -S mingw-w64-x86_64-nlohmann-json` for installation. Please file issues [here](https://github.com/msys2/MINGW-packages/issues/new?title=%5Bnlohmann-json%5D) if you experience problems with the packages.
-
-If you are using [MacPorts](https://ports.macports.org), execute `sudo port install nlohmann-json` to install the [nlohmann-json](https://ports.macports.org/port/nlohmann-json/) package.
-
-If you are using [`build2`](https://build2.org), you can use the [`nlohmann-json`](https://cppget.org/nlohmann-json) package from the public repository https://cppget.org or directly from the [package's sources repository](https://github.com/build2-packaging/nlohmann-json). In your project's `manifest` file, just add `depends: nlohmann-json` (probably with some [version constraints](https://build2.org/build2-toolchain/doc/build2-toolchain-intro.xhtml#guide-add-remove-deps)). If you are not familiar with using dependencies in `build2`, [please read this introduction](https://build2.org/build2-toolchain/doc/build2-toolchain-intro.xhtml).
-Please file issues [here](https://github.com/build2-packaging/nlohmann-json) if you experience problems with the packages.
-
-If you are using [`wsjcpp`](https://wsjcpp.org), you can use the command `wsjcpp install "https://github.com/nlohmann/json:develop"` to get the latest version. Note you can change the branch ":develop" to an existing tag or another branch.
-
-If you are using [`CPM.cmake`](https://github.com/TheLartians/CPM.cmake), you can check this [`example`](https://github.com/TheLartians/CPM.cmake/tree/master/examples/json). After [adding CPM script](https://github.com/TheLartians/CPM.cmake#adding-cpm) to your project, implement the following snippet to your CMake:
-
-```cmake
-CPMAddPackage(
-    NAME nlohmann_json
-    GITHUB_REPOSITORY nlohmann/json
-    VERSION 3.9.1)
-```
-
-### Pkg-config
-
-If you are using bare Makefiles, you can use `pkg-config` to generate the include flags that point to where the library is installed:
-
-```sh
-pkg-config nlohmann_json --cflags
-```
-
-Users of the Meson build system will also be able to use a system-wide library, which will be found by `pkg-config`:
-
-```meson
-json = dependency('nlohmann_json', required: true)
-```

-## Projects using JSON for Modern C++
-
-The library is currently used in Apple macOS Sierra and iOS 10. I am not sure what they are using the library for, but I am happy that it runs on so many devices.
-
-
-## Notes
-
-### Character encoding
-
-The library supports **Unicode input** as follows:
-
-- Only **UTF-8** encoded input is supported which is the default encoding for JSON according to [RFC 8259](https://tools.ietf.org/html/rfc8259.html#section-8.1).
-- `std::u16string` and `std::u32string` can be parsed, assuming UTF-16 and UTF-32 encoding, respectively. These encodings are not supported when reading from files or other input containers.
-- Other encodings such as Latin-1 or ISO 8859-1 are **not** supported and will yield parse or serialization errors.
-- [Unicode noncharacters](https://www.unicode.org/faq/private_use.html#nonchar1) will not be replaced by the library.
-- Invalid surrogates (e.g., incomplete pairs such as `\uDEAD`) will yield parse errors.
-- The strings stored in the library are UTF-8 encoded. When using the default string type (`std::string`), note that its length/size functions return the number of stored bytes rather than the number of characters or glyphs.
-- When you store strings with different encodings in the library, calling [`dump()`](https://nlohmann.github.io/json/api/basic_json/dump/) may throw an exception unless `json::error_handler_t::replace` or `json::error_handler_t::ignore` are used as error handlers.
-- To store wide strings (e.g., `std::wstring`), you need to convert them to a UTF-8 encoded `std::string` before, see [an example](https://json.nlohmann.me/home/faq/#wide-string-handling).
-
-### Comments in JSON
-
-This library does not support comments by default. It does so for three reasons:
-
-1. Comments are not part of the [JSON specification](https://tools.ietf.org/html/rfc8259). You may argue that `//` or `/* */` are allowed in JavaScript, but JSON is not JavaScript.
-2. This was not an oversight: Douglas Crockford [wrote on this](https://plus.google.com/118095276221607585885/posts/RK8qyGVaGSr) in May 2012:
-
-	> I removed comments from JSON because I saw people were using them to hold parsing directives, a practice which would have destroyed interoperability.  I know that the lack of comments makes some people sad, but it shouldn't.
-
-	> Suppose you are using JSON to keep configuration files, which you would like to annotate. Go ahead and insert all the comments you like. Then pipe it through JSMin before handing it to your JSON parser.
-
-3. It is dangerous for interoperability if some libraries would add comment support while others don't. Please check [The Harmful Consequences of the Robustness Principle](https://tools.ietf.org/html/draft-iab-protocol-maintenance-01) on this.
-
-However, you can pass set parameter `ignore_comments` to true in the `parse` function to ignore `//` or `/* */` comments. Comments will then be treated as whitespace.
-
-### Order of object keys
-
-By default, the library does not preserve the **insertion order of object elements**. This is standards-compliant, as the [JSON standard](https://tools.ietf.org/html/rfc8259.html) defines objects as "an unordered collection of zero or more name/value pairs".
-
-If you do want to preserve the insertion order, you can try the type [`nlohmann::ordered_json`](https://github.com/nlohmann/json/issues/2179). Alternatively, you can use a more sophisticated ordered map like [`tsl::ordered_map`](https://github.com/Tessil/ordered-map) ([integration](https://github.com/nlohmann/json/issues/546#issuecomment-304447518)) or [`nlohmann::fifo_map`](https://github.com/nlohmann/fifo_map) ([integration](https://github.com/nlohmann/json/issues/485#issuecomment-333652309)).
-
-### Memory Release
-
-We checked with Valgrind and the Address Sanitizer (ASAN) that there are no memory leaks.
-
-If you find that a parsing program with this library does not release memory, please consider the following case, and it may be unrelated to this library.
-
-**Your program is compiled with glibc.** There is a tunable threshold that glibc uses to decide whether to actually return memory to the system or whether to cache it for later reuse. If in your program you make lots of small allocations and those small allocations are not a contiguous block and are presumably below the threshold, then they will not get returned to the OS.
-Here is a related issue [#1924](https://github.com/nlohmann/json/issues/1924).
-
-### Further notes
-
-- The code contains numerous debug **assertions** which can be switched off by defining the preprocessor macro `NDEBUG`, see the [documentation of `assert`](https://en.cppreference.com/w/cpp/error/assert). In particular, note [`operator[]`](https://nlohmann.github.io/json/api/basic_json/operator%5B%5D/) implements **unchecked access** for const objects: If the given key is not present, the behavior is undefined (think of a dereferenced null pointer) and yields an [assertion failure](https://github.com/nlohmann/json/issues/289) if assertions are switched on. If you are not sure whether an element in an object exists, use checked access with the [`at()` function](https://nlohmann.github.io/json/api/basic_json/at/). Furthermore, you can define `JSON_ASSERT(x)` to replace calls to `assert(x)`.
-- As the exact number type is not defined in the [JSON specification](https://tools.ietf.org/html/rfc8259.html), this library tries to choose the best fitting C++ number type automatically. As a result, the type `double` may be used to store numbers which may yield [**floating-point exceptions**](https://github.com/nlohmann/json/issues/181) in certain rare situations if floating-point exceptions have been unmasked in the calling code. These exceptions are not caused by the library and need to be fixed in the calling code, such as by re-masking the exceptions prior to calling library functions.
-- The code can be compiled without C++ **runtime type identification** features; that is, you can use the `-fno-rtti` compiler flag.
-- **Exceptions** are used widely within the library. They can, however, be switched off with either using the compiler flag `-fno-exceptions` or by defining the symbol `JSON_NOEXCEPTION`. In this case, exceptions are replaced by `abort()` calls. You can further control this behavior by defining `JSON_THROW_USER` (overriding `throw`), `JSON_TRY_USER` (overriding `try`), and `JSON_CATCH_USER` (overriding `catch`). Note that `JSON_THROW_USER` should leave the current scope (e.g., by throwing or aborting), as continuing after it may yield undefined behavior. Note the explanatory [`what()`](https://en.cppreference.com/w/cpp/error/exception/what) string of exceptions is not available for MSVC if exceptions are disabled, see [#2824](https://github.com/nlohmann/json/discussions/2824).
-
-## Execute unit tests
-
-To compile and run the tests, you need to execute
-
-```sh
-$ mkdir build
-$ cd build
-$ cmake .. -DJSON_BuildTests=On
-$ cmake --build .
-$ ctest --output-on-failure
-```
-
-Note that during the `ctest` stage, several JSON test files are downloaded from an [external repository](https://github.com/nlohmann/json_test_data). If policies forbid downloading artifacts during testing, you can download the files yourself and pass the directory with the test files via `-DJSON_TestDataDirectory=path` to CMake. Then, no Internet connectivity is required. See [issue #2189](https://github.com/nlohmann/json/issues/2189) for more information.
-
-In case you have downloaded the library rather than checked out the code via Git, test `cmake_fetch_content_configure` will fail. Please execute `ctest -LE git_required` to skip these tests. See [issue #2189](https://github.com/nlohmann/json/issues/2189) for more information.
-
-Some tests change the installed files and hence make the whole process not reproducible. Please execute `ctest -LE not_reproducible` to skip these tests. See [issue #2324](https://github.com/nlohmann/json/issues/2324) for more information.
-
-Note you need to call `cmake -LE "not_reproducible|git_required"` to exclude both labels. See [issue #2596](https://github.com/nlohmann/json/issues/2596) for more information.
-
-As Intel compilers use unsafe floating point optimization by default, the unit tests may fail. Use flag [`/fp:precise`](https://software.intel.com/content/www/us/en/develop/documentation/cpp-compiler-developer-guide-and-reference/top/compiler-reference/compiler-options/compiler-option-details/floating-point-options/fp-model-fp.html) then.

-# Container function overview
-
-The container functions known from STL have been extended to support the different value types from JSON. However, not all functions can be applied to all value types. Note that the signature of some functions differ between the types; for instance, `at` may be called with either a string to address a key in an object or with an integer to address a value in an array.
-
-Note that this table only lists those exceptions thrown due to the type. For instance, the @link nlohmann::basic_json::at(const typename object_t::key_type & key) `at` @endlink function will always throw a @link nlohmann::basic_json::type_error `json::type_error` @endlink exception when called for a string type. When called for an array, it *may* throw an @link nlohmann::basic_json::out_of_range `json::out_of_range` @endlink exception if the passed index is invalid.

-
-Serializer that uses ADL ([Argument-Dependent Lookup](https://en.cppreference.com/w/cpp/language/adl)) to choose
-`to_json`/`from_json` functions from the types' namespaces.
-
-It is implemented similar to
-
-```cpp
-template<typename ValueType>
-struct adl_serializer {
-    template<typename BasicJsonType>
-    static void to_json(BasicJsonType& j, const T& value) {
-        // calls the "to_json" method in T's namespace
-    }
-
-    template<typename BasicJsonType>
-    static void from_json(const BasicJsonType& j, T& value) {
-        // same thing, but with the "from_json" method
-    }
-};
-```
-
-## Member functions
-
-- [**from_json**](from_json.md) - convert a JSON value to any value type
-- [**to_json**](to_json.md) - convert any value type to a JSON value

-static bool accept(InputType&& i,
-                   const bool ignore_comments = false);
-
-// (2)

-static bool accept(IteratorType first, IteratorType last,
-                   const bool ignore_comments = false);
-```
-
-Checks whether the input is valid JSON.
-
-1. Reads from a compatible input.
-2. Reads from a pair of character iterators
-    
-    The value_type of the iterator must be an integral type with size of 1, 2 or 4 bytes, which will be interpreted
-    respectively as UTF-8, UTF-16 and UTF-32.
-    
-Unlike the [`parse`](parse.md) function, this function neither throws an exception in case of invalid JSON input
-(i.e., a parse error) nor creates diagnostic information.
-
-## Template parameters
-
-`InputType`
-:   A compatible input, for instance:
-    
-    - an `std::istream` object
-    - a `FILE` pointer
-    - a C-style array of characters
-    - a pointer to a null-terminated string of single byte characters
-    - an object `obj` for which `begin(obj)` and `end(obj)` produces a valid pair of iterators.
-
-`IteratorType`
-:   a compatible iterator type
-
-## Parameters
-
-`i` (in)
-:   Input to parse from.
-
-`ignore_comments` (in)
-:   whether comments should be ignored and treated like whitespace (`#!cpp true`) or yield a parse error
-    (`#!cpp false`); (optional, `#!cpp false` by default)
-
-`first` (in)
-:   iterator to start of character range
-
-`last` (in)
-:   iterator to end of character range
-
-## Return value
-
-Whether the input is valid JSON.
-
-## Exception safety
-

-# <small>nlohmann::basic_json::</small>array
-
-```cpp
-static basic_json array(initializer_list_t init = {});
-```
-
-Creates a JSON array value from a given initializer list. That is, given a list of values `a, b, c`, creates the JSON
-value `#!json [a, b, c]`. If the initializer list is empty, the empty array `#!json []` is created.
-
-## Parameters
-
-`init` (in)
-:   initializer list with JSON values to create an array from (optional)
-
-## Return value
-
-JSON array value
-
-## Exception safety
-
-Strong guarantee: if an exception is thrown, there are no changes in the JSON value.
-
-## Complexity
-
-Linear in the size of `init`.
-
-## Notes
-
-This function is only needed to express two edge cases that cannot be realized with the initializer list constructor
-([`basic_json(initializer_list_t, bool, value_t)`](basic_json.md)). These cases are:
-
-1. creating an array whose elements are all pairs whose first element is a string -- in this case, the initializer list
-   constructor would create an object, taking the first elements as keys
-2. creating an empty array -- passing the empty initializer list to the initializer list constructor yields an empty
-   object
-
-## Examples
-
-??? example
-
-    The following code shows an example for the `array` function.
-
-    ```cpp
-    --8<-- "examples/array.cpp"
-    ```

-    Output:

-# <small>nlohmann::basic_json::</small>array_t
-
-```cpp
-using array_t = ArrayType<basic_json, AllocatorType<basic_json>>;
-```
-
-The type used to store JSON arrays.
-
-[RFC 8259](https://tools.ietf.org/html/rfc8259) describes JSON arrays as follows:
-> An array is an ordered sequence of zero or more values.
-
-To store objects in C++, a type is defined by the template parameters explained below.
-
-## Template parameters
-
-`ArrayType`
-:   container type to store arrays (e.g., `std::vector` or `std::list`)
-
-`AllocatorType`
-:   the allocator to use for objects (e.g., `std::allocator`)
-
-## Notes
-
-#### Default type
-
-With the default values for `ArrayType` (`std::vector`) and `AllocatorType` (`std::allocator`), the default value for
-`array_t` is:
-
-```cpp
-std::vector<
-  basic_json, // value_type
-  std::allocator<basic_json> // allocator_type
->
-```
-
-#### Limits
-
-[RFC 8259](https://tools.ietf.org/html/rfc8259) specifies:
-> An implementation may set limits on the maximum depth of nesting.
-
-In this class, the array's limit of nesting is not explicitly constrained. However, a maximum depth of nesting may be
-introduced by the compiler or runtime environment. A theoretical limit can be queried by calling the
-[`max_size`](max_size.md) function of a JSON array.
-
-#### Storage
-
-Arrays are stored as pointers in a `basic_json` type. That is, for any access to array values, a pointer of type
-`#!cpp array_t*` must be dereferenced.
-
-## Examples
-
-??? example
-
-    The following code shows that `array_t` is by default, a typedef to `#!cpp std::vector<nlohmann::json>`.
-     
-    ```cpp
-    --8<-- "examples/array_t.cpp"
-    ```
-    
-    Output:
-    
-    ```json
-    --8<-- "examples/array_t.output"

-## Exceptions
-
-1. The function can throw the following exceptions:
-    - Throws [`type_error.304`](../../home/exceptions.md#jsonexceptiontype_error304) if the JSON value is not an array;
-      in this case, calling `at` with an index makes no sense. See example below.
-    - Throws [`out_of_range.401`](../../home/exceptions.md#jsonexceptionout_of_range401) if the index `idx` is out of
-      range of the array; that is, `idx >= size()`. See example below.
-2. The function can throw the following exceptions:
-    - Throws [`type_error.304`](../../home/exceptions.md#jsonexceptiontype_error304) if the JSON value is not an object;
-      in this case, calling `at` with a key makes no sense. See example below.
-    - Throws [`out_of_range.403`](../../home/exceptions.md#jsonexceptionout_of_range403) if the key `key` is not
-      stored in the object; that is, `find(key) == end()`. See example below.
-3. The function can throw the following exceptions:
-    - Throws [`parse_error.106`](../../home/exceptions.md#jsonexceptionparse_error106) if an array index in the passed
-      JSON pointer `ptr` begins with '0'. See example below.
-    - Throws [`parse_error.109`](../../home/exceptions.md#jsonexceptionparse_error109) if an array index in the passed
-      JSON pointer `ptr` is not a number. See example below.
-    - Throws [`out_of_range.401`](../../home/exceptions.md#jsonexceptionout_of_range401) if an array index in the passed
-      JSON pointer `ptr` is out of range. See example below.
-    - Throws [`out_of_range.402`](../../home/exceptions.md#jsonexceptionout_of_range402) if the array index '-' is used
-      in the passed JSON pointer `ptr`. As `at` provides checked access (and no elements are implicitly inserted), the
-      index '-' is always invalid. See example below.
-    - Throws [`out_of_range.403`](../../home/exceptions.md#jsonexceptionout_of_range403) if the JSON pointer describes a
-      key of an object which cannot be found. See example below.
-    - Throws [`out_of_range.404`](../../home/exceptions.md#jsonexceptionout_of_range404) if the JSON pointer `ptr` can
-      not be resolved. See example below.
-
-## Complexity
-
-1. Constant
-2. Logarithmic in the size of the container.
-3. Constant

-
-1. Create an empty JSON value with a given type. The value will be default initialized with an empty value which depends
-   on the type:
-   
-    | Value type | initial value  |
-    |------------|----------------|
-    | null       | `#!json null`  |
-    | boolean    | `#!json false` |
-    | string     | `#!json ""`    |
-    | number     | `#!json 0`     |
-    | object     | `#!json {}`    |
-    | array      | `#!json []`    |
-    | binary     | empty array    |
-
-    The postcondition of this constructor can be restored by calling [`clear()`](clear.md).
-
-2. Create a `#!json null` JSON value. It either takes a null pointer as parameter (explicitly creating `#!json null`)
-   or no parameter (implicitly creating `#!json null`). The passed null pointer itself is not read -- it is only used to
-   choose the right constructor.
-
-3. This is a "catch all" constructor for all compatible JSON types; that is, types for which a `to_json()` method
-   exists. The constructor forwards the parameter `val` to that method (to `json_serializer<U>::to_json` method with
-   `U = uncvref_t<CompatibleType>`, to be exact).
-   
-    Template type `CompatibleType` includes, but is not limited to, the following types:
-
-    - **arrays**: [`array_t`](array_t.md) and all kinds of compatible containers such as `std::vector`, `std::deque`,
-     `std::list`, `std::forward_list`, `std::array`, `std::valarray`, `std::set`, `std::unordered_set`, `std::multiset`,
-     and `std::unordered_multiset` with a `value_type` from which a `basic_json` value can be constructed.
-    - **objects**: [`object_t`](object_t.md) and all kinds of compatible associative containers such as `std::map`,
-     `std::unordered_map`, `std::multimap`, and `std::unordered_multimap` with a `key_type` compatible to `string_t`
-     and a `value_type` from which a `basic_json` value can be constructed.
-    - **strings**: `string_t`, string literals, and all compatible string containers can be used.
-    - **numbers**: [`number_integer_t`](number_integer_t.md), [`number_unsigned_t`](number_unsigned_t.md),
-     [`number_float_t`](number_float_t.md), and all convertible number types such as `int`, `size_t`, `int64_t`, `float`
-     or `double` can be used.
-    - **boolean**: `boolean_t` / `bool` can be used.
-    - **binary**: `binary_t` / `std::vector<uint8_t>` may be used; unfortunately because string literals cannot be
-     distinguished from binary character arrays by the C++ type system, all types compatible with `const char*` will be
-     directed to the string constructor instead. This is both for backwards compatibility, and due to the fact that a
-     binary type is not a standard JSON type.
-    
-    See the examples below.
-
-4. This is a constructor for existing `basic_json` types. It does not hijack copy/move constructors, since the parameter
-   has different template arguments than the current ones.
-
-    The constructor tries to convert the internal `m_value` of the parameter.
-
-5. Creates a JSON value of type array or object from the passed initializer list `init`. In case `type_deduction` is
-   `#!cpp true` (default), the type of the JSON value to be created is deducted from the initializer list `init`
-   according to the following rules:
-   
-    1. If the list is empty, an empty JSON object value `{}` is created.
-    2. If the list consists of pairs whose first element is a string, a JSON object value is created where the first
-      elements of the pairs are treated as keys and the second elements are as values.
-    3. In all other cases, an array is created.
-    
-    The rules aim to create the best fit between a C++ initializer list and JSON values. The rationale is as follows:
-    
-    1. The empty initializer list is written as `#!cpp {}` which is exactly an empty JSON object.
-    2. C++ has no way of describing mapped types other than to list a list of pairs. As JSON requires that keys must be
-       of type string, rule 2 is the weakest constraint one can pose on initializer lists to interpret them as an
-       object.
-    3. In all other cases, the initializer list could not be interpreted as JSON object type, so interpreting it as JSON
-       array type is safe.
-    
-    With the rules described above, the following JSON values cannot be expressed by an initializer list:
-    
-    - the empty array (`#!json []`): use `array(initializer_list_t)` with an empty initializer list in this case
-    - arrays whose elements satisfy rule 2: use `array(initializer_list_t)` with the same initializer list in this case
-   
-    Function [`array()`](array.md) and [`object()`](object.md) force array and object creation from initializer lists,
-    respectively.
-        
-6. Constructs a JSON array value by creating `cnt` copies of a passed value. In case `cnt` is `0`, an empty array is
-   created.
-
-7. Constructs the JSON value with the contents of the range `[first, last)`. The semantics depends on the different
-   types a JSON value can have:
-
-    - In case of a `#!json null` type, [invalid_iterator.206](../../home/exceptions.md#jsonexceptioninvalid_iterator206)
-      is thrown.
-    - In case of other primitive types (number, boolean, or string), `first` must be `begin()` and `last` must be
-      `end()`. In this case, the value is copied. Otherwise,
-      [`invalid_iterator.204`](../../home/exceptions.md#jsonexceptioninvalid_iterator204) is thrown.
-    - In case of structured types (array, object), the constructor behaves as similar versions for `std::vector` or
-      `std::map`; that is, a JSON array or object is constructed from the values in the range.
-
-8. Creates a copy of a given JSON value.
-
-9. Move constructor. Constructs a JSON value with the contents of the given value `other` using move semantics. It
-   "steals" the resources from `other` and leaves it as JSON `#!json null` value.
-
-## Template parameters
-
-`CompatibleType`
-:   a type such that:
-
-    - `CompatibleType` is not derived from `std::istream`,
-    - `CompatibleType` is not `basic_json` (to avoid hijacking copy/move constructors),
-    - `CompatibleType` is not a different `basic_json` type (i.e. with different template arguments)
-    - `CompatibleType` is not a `basic_json` nested type (e.g., `json_pointer`, `iterator`, etc.)
-    - `json_serializer<U>` (with `U = uncvref_t<CompatibleType>`) has a `to_json(basic_json_t&, CompatibleType&&)`
-       method
-
-`BasicJsonType`:
-:   a type such that:
-
-    - `BasicJsonType` is a `basic_json` type.
-    - `BasicJsonType` has different template arguments than `basic_json_t`.
-
-`U`:
-:   `uncvref_t<CompatibleType>`
-
-## Parameters
-
-`v` (in)
-:   the type of the value to create
-
-`val` (in)
-:   the value to be forwarded to the respective constructor
-
-`init` (in)
-:   initializer list with JSON values
-
-`type_deduction` (in)
-:   internal parameter; when set to `#!cpp true`, the type of the JSON value is deducted from the initializer list
-    `init`; when set to `#!cpp false`, the type provided via `manual_type` is forced. This mode is used by the functions

-## Exceptions
-
-1. /
-2. The function does not throw exceptions.
-3. /
-4. /
-5. The function can throw the following exceptions:
-    - Throws [`type_error.301`](../../home/exceptions.md#jsonexceptiontype_error301) if `type_deduction` is
-      `#!cpp false`, `manual_type` is `value_t::object`, but `init` contains an element which is not a pair whose first
-      element is a string. In this case, the constructor could not create an object. If `type_deduction` would have been
-      `#!cpp true`, an array would have been created. See `object(initializer_list_t)` for an example.
-6. /
-7. The function can throw the following exceptions:
-    - Throws [`invalid_iterator.201`](../../home/exceptions.md#jsonexceptioninvalid_iterator201) if iterators `first`
-      and `last` are not compatible (i.e., do not belong to the same JSON value). In this case, the range
-      `[first, last)` is undefined.
-    - Throws [`invalid_iterator.204`](../../home/exceptions.md#jsonexceptioninvalid_iterator204) if iterators `first`
-      and `last` belong to a primitive type (number, boolean, or string), but `first` does not point to the first
-      element anymore. In this case, the range `[first, last)` is undefined. See example code below.
-    - Throws [`invalid_iterator.206`](../../home/exceptions.md#jsonexceptioninvalid_iterator206) if iterators `first`
-      and `last` belong to a `#!json null` value. In this case, the range `[first, last)` is undefined.
-8. /
-9. The function does not throw exceptions.
-
-## Complexity
-
-1. Constant.
-2. Constant.
-3. Usually linear in the size of the passed `val`, also depending on the implementation of the called `to_json()`
-   method.
-4. Usually linear in the size of the passed `val`, also depending on the implementation of the called `to_json()`
-   method.
-5. Linear in the size of the initializer list `init`.
-6. Linear in `cnt`.
-7. Linear in distance between `first` and `last`.
-8. Linear in the size of `other`.
-9. Constant.

-## Notes
-
-- Overload 5:
-
-    !!! note
-
-        When used without parentheses around an empty initializer list, `basic_json()` is called instead of this
-        function, yielding the JSON `#!json null` value.
-
-- Overload 7:
-
-    !!! info "Preconditions"
-
-        - Iterators `first` and `last` must be initialized. **This precondition is enforced with an assertion (see
-          warning).** If assertions are switched off, a violation of this precondition yields undefined behavior.
-        - Range `[first, last)` is valid. Usually, this precondition cannot be checked efficiently. Only certain edge
-          cases are detected; see the description of the exceptions above. A violation of this precondition yields
-          undefined behavior.
-    
-    !!! warning
-
-        A precondition is enforced with a runtime assertion that will result in calling `std::abort` if this
-        precondition is not met. Assertions can be disabled by defining `NDEBUG` at compile time. See
-        <https://en.cppreference.com/w/cpp/error/assert> for more information.
-    
-- Overload 8:
-
-    !!! info "Postcondition"
-
-        `#!cpp *this == other`
-
-- Overload 9:
-
-    !!! info "Postconditions"
-
-        - `#!cpp `*this` has the same value as `other` before the call.
-        - `other` is a JSON `#!json null` value
-

- 
-Binary values are part of various binary formats, such as CBOR, MessagePack, and BSON. This constructor is used to

-
-## Parameters

-
-`subtype` (in)
-:   subtype to use in CBOR, MessagePack, and BSON
-
-## Return value

-## Notes

-Note, this function exists because of the difficulty in correctly specifying the correct template overload in the
-standard value ctor, as both JSON arrays and JSON binary arrays are backed with some form of a `std::vector`. Because
-JSON binary arrays are a non-standard extension it was decided that it would be best to prevent automatic initialization
-of a binary array type, for backwards compatibility and so it does not happen on accident.

-# <small>nlohmann::basic_json::</small>binary_t
-
-```cpp
-using binary_t = byte_container_with_subtype<BinaryType>;
-```
-
-This type is a type designed to carry binary data that appears in various serialized formats, such as CBOR's Major Type
-2, MessagePack's bin, and BSON's generic binary subtype. This type is NOT a part of standard JSON and exists solely for
-compatibility with these binary types. As such, it is simply defined as an ordered sequence of zero or more byte values.
-
-Additionally, as an implementation detail, the subtype of the binary data is carried around as a `std::uint64_t`, which
-is compatible with both of the binary data formats that use binary subtyping, (though the specific numbering is
-incompatible with each other, and it is up to the user to translate between them). The subtype is added to `BinaryType`
-via the helper type [byte_container_with_subtype](../byte_container_with_subtype/index.md).
-
-[CBOR's RFC 7049](https://tools.ietf.org/html/rfc7049) describes this type as:
-> Major type 2: a byte string. The string's length in bytes is represented following the rules for positive integers
-> (major type 0).
-
-[MessagePack's documentation on the bin type
-family](https://github.com/msgpack/msgpack/blob/master/spec.md#bin-format-family) describes this type as:
-> Bin format family stores a byte array in 2, 3, or 5 bytes of extra bytes in addition to the size of the byte array.
-
-[BSON's specifications](http://bsonspec.org/spec.html) describe several binary types; however, this type is intended to
-represent the generic binary type which has the description:
-> Generic binary subtype - This is the most commonly used binary subtype and should be the 'default' for drivers and
-> tools.
-
-None of these impose any limitations on the internal representation other than the basic unit of storage be some type of
-array whose parts are decomposable into bytes.
-
-The default representation of this binary format is a `#!cpp std::vector<std::uint8_t>`, which is a very common way to
-represent a byte array in modern C++.
-
-## Template parameters
-
-`BinaryType`
-:   container type to store arrays
-
-## Notes
-
-#### Default type
-
-The default values for `BinaryType` is `#!cpp std::vector<std::uint8_t>`.
-
-#### Storage
-
-Binary Arrays are stored as pointers in a `basic_json` type. That is, for any access to array values, a pointer of the
-type `#!cpp binary_t*` must be dereferenced.
-
-#### Notes on subtypes
-
-- CBOR
-    - Binary values are represented as byte strings. Subtypes are written as tags.
-
-- MessagePack
-    - If a subtype is given and the binary array contains exactly 1, 2, 4, 8, or 16 elements, the fixext family (fixext1,
-      fixext2, fixext4, fixext8) is used. For other sizes, the ext family (ext8, ext16, ext32) is used. The subtype is
-      then added as signed 8-bit integer.
-    - If no subtype is given, the bin family (bin8, bin16, bin32) is used.
-
-- BSON
-    - If a subtype is given, it is used and added as unsigned 8-bit integer.
-    - If no subtype is given, the generic binary subtype 0x00 is used.
-
-## Examples
-

-
-```cpp
-// (1)
-template<typename KeyT>
-bool contains(KeyT && key) const;
-
-// (2)
-bool contains(const json_pointer& ptr) const;
-```
-
-1. Check whether an element exists in a JSON object with key equivalent to `key`. If the element is not found or the 
-   JSON value is not an object, `#!cpp false` is returned.
-2. Check whether the given JSON pointer `ptr` can be resolved in the current JSON value.
-
-## Template parameters
-
-`KeyT`
-:   A type for an object key other than `basic_json::json_pointer`.
-
-## Parameters
-
-`key` (in)
-:   key value to check its existence.
-
-`ptr` (in)
-:   JSON pointer to check its existence.
-
-## Return value
-
-1. `#!cpp true` if an element with specified `key` exists. If no such element with such key is found or the JSON value
-   is not an object, `#!cpp false` is returned.
-2. `#!cpp true` if the JSON pointer can be resolved to a stored value, `#!cpp false` otherwise.
-
-## Exception safety
-
-Strong exception safety: if an exception occurs, the original value stays intact.
-
-## Exceptions
-
-1. The function does not throw exceptions.
-2. The function can throw the following exceptions:
-    - Throws [`parse_error.106`](../../home/exceptions.md#jsonexceptionparse_error106) if an array index begins with
-      `0`.
-    - Throws [`parse_error.109`](../../home/exceptions.md#jsonexceptionparse_error109) if an array index was not a
-      number.
-
-## Complexity
-
-Logarithmic in the size of the JSON object.
-
-## Notes
-
-1. This method always returns `#!cpp false` when executed on a JSON type that is not an object.
-2. This method can be executed on any JSON value type.
-
-!!! info "Postconditions"
-
-    If `#!cpp j.contains(x)` returns `#!c true` for a key or JSON pointer `x`, then it is safe to call `j[x]`.

-
-Serialization function for JSON values. The function tries to mimic Python's
-[`json.dumps()` function](https://docs.python.org/2/library/json.html#json.dump), and currently  supports its `indent`
-and `ensure_ascii` parameters.
-    
-## Parameters
-
-`indent` (in)
-:   If `indent` is nonnegative, then array elements and object members will be pretty-printed with that indent level. An
-    indent level of `0` will only insert newlines. `-1` (the default) selects the most compact representation.
-
-`indent_char` (in)
-:   The character to use for indentation if `indent` is greater than `0`. The default is ` ` (space).
-
-`ensure_ascii` (in)
-:   If `ensure_ascii` is true, all non-ASCII characters in the output are escaped with `\uXXXX` sequences, and the
-    result consists of ASCII characters only.
-
-`error_handler` (in)
-:   how to react on decoding errors; there are three possible values (see [`error_handler_t`](error_handler_t.md):
-    `strict` (throws and exception in case a decoding error occurs; default), `replace` (replace invalid UTF-8 sequences
-    with U+FFFD), and `ignore` (ignore invalid UTF-8 sequences during serialization; all bytes are copied to the output
-    unchanged)).
-    
-## Return value
-
-string containing the serialization of the JSON value
-
-## Exception safety
-
-Strong guarantee: if an exception is thrown, there are no changes to any JSON value.
-
-## Exceptions
-
-Throws [`type_error.316`](../../home/exceptions.md#jsonexceptiontype_error316) if a string stored inside the JSON value
-is not UTF-8 encoded and `error_handler` is set to `strict`
-
-## Complexity
-
-Linear.
-
-## Notes
-
-Binary values are serialized as object containing two keys:
-
-- "bytes": an array of bytes as integers
-- "subtype": the subtype as integer or `#!json null` if the binary has no subtype
-
-## Examples
-
-??? example
-
-    The following example shows the effect of different `indent`, `indent_char`, and `ensure_ascii` parameters to the

-
-1. Removes an element from a JSON value specified by iterator `pos`. The iterator `pos` must be valid and
-   dereferenceable. Thus, the `end()` iterator (which is valid, but is not dereferenceable) cannot be used as a value for
-   `pos`.
-   
-    If called on a primitive type other than `#!json null`, the resulting JSON value will be `#!json null`.
-
-2. Remove an element range specified by `[first; last)` from a JSON value. The iterator `first` does not need to be
-   dereferenceable if `first == last`: erasing an empty range is a no-op.
-   
-    If called on a primitive type other than `#!json null`, the resulting JSON value will be `#!json null`.
-
-3. Removes an element from a JSON object by key.

-    
-`idx` (in)

-    
-## Return value
-
-1. Iterator following the last removed element. If the iterator `pos` refers to the last element, the `end()` iterator
-   is returned.
-2. Iterator following the last removed element. If the iterator `last` refers to the last element, the `end()` iterator
-   is returned.
-3. Number of elements removed. If `ObjectType` is the default `std::map` type, the return value will always be `0`

-## Exception safety
-
-Strong exception safety: if an exception occurs, the original value stays intact.
-
-## Exceptions
-
-1. The function can throw the following exceptions:
-    - Throws [`type_error.307`](../../home/exceptions.md#jsonexceptiontype_error307) if called on a `null` value;
-      example: `"cannot use erase() with null"`
-    - Throws [`invalid_iterator.202`](../../home/exceptions.md#jsonexceptioninvalid_iterator202) if called on an
-      iterator which does not belong to the current JSON value; example: `"iterator does not fit current value"`
-    - Throws [`invalid_iterator.205`](../../home/exceptions.md#jsonexceptioninvalid_iterator205) if called on a
-      primitive type with invalid iterator (i.e., any iterator which is not `begin()`); example: `"iterator out of
-      range"`
-2. The function can throw the following exceptions:
-    - Throws [`type_error.307`](../../home/exceptions.md#jsonexceptiontype_error307) if called on a `null` value;
-      example: `"cannot use erase() with null"`
-    - Throws [`invalid_iterator.203`](../../home/exceptions.md#jsonexceptioninvalid_iterator203) if called on iterators
-      which does not belong to the current JSON value; example: `"iterators do not fit current value"`
-    - Throws [`invalid_iterator.204`](../../home/exceptions.md#jsonexceptioninvalid_iterator204) if called on a
-      primitive type with invalid iterators (i.e., if `first != begin()` and `last != end()`); example: `"iterators out
-      of range"`
-3. The function can throw the following exceptions:
-    - Throws [`type_error.307`](../../home/exceptions.md#jsonexceptiontype_error307) when called on a type other than
-      JSON object; example: `"cannot use erase() with null"`
-4. The function can throw the following exceptions:
-    - Throws [`type_error.307`](../../home/exceptions.md#jsonexceptiontype_error307) when called on a type other than
-      JSON object; example: `"cannot use erase() with null"`
-    - Throws [`out_of_range.401`](../../home/exceptions.md#jsonexceptionout_of_range401) when `idx >= size()`; example:
-      `"array index 17 is out of range"`
-
-## Complexity
-
-1. The complexity depends on the type:
-       - objects: amortized constant
-       - arrays: linear in distance between `pos` and the end of the container
-       - strings and binary: linear in the length of the member
-       - other types: constant
-2. The complexity depends on the type:
-       - objects: `log(size()) + std::distance(first, last)`
-       - arrays: linear in the distance between `first` and `last`, plus linear
-         in the distance between `last` and end of the container
-       - strings and binary: linear in the length of the member
-       - other types: constant
-3. `log(size()) + count(key)`
-4. Linear in distance between `idx` and the end of the container.
-
-## Notes
-
-1. Invalidates iterators and references at or after the point of the `erase`, including the `end()` iterator.
-2. /
-3. References and iterators to the erased elements are invalidated. Other references and iterators are not affected.
-4. /

-## Template parameters
-
-`InputType`
-:   A compatible input, for instance:
-    
-    - an `std::istream` object
-    - a `FILE` pointer
-    - a C-style array of characters
-    - a pointer to a null-terminated string of single byte characters
-    - an object `obj` for which `begin(obj)` and `end(obj)` produces a valid pair of iterators.
-
-`IteratorType`
-:   a compatible iterator type
-
-## Parameters
-
-`i` (in)
-:   an input in MessagePack format convertible to an input adapter
-
-`first` (in)
-:   iterator to start of the input
-
-`last` (in)
-:   iterator to end of the input
-
-`strict` (in)
-:   whether to expect the input to be consumed until EOF (`#!cpp true` by default)
-
-`allow_exceptions` (in)
-:   whether to throw exceptions in case of a parse error (optional, `#!cpp true` by default)
-
-## Return value
-
-deserialized JSON value; in case of a parse error and `allow_exceptions` set to `#!cpp false`, the return value will be
-`value_t::discarded`.  The latter can be checked with [`is_discarded`](is_discarded.md).
-
-## Exception safety
-
-Strong guarantee: if an exception is thrown, there are no changes in the JSON value.
-
-## Exceptions
-
-- Throws [parse_error.110](../../home/exceptions.md#jsonexceptionparse_error110) if the given input ends prematurely or
-  the end of  file was not reached when `strict` was set to true
-- Throws [parse_error.112](../../home/exceptions.md#jsonexceptionparse_error112) if unsupported features from
-  MessagePack were used in the given input or if the input is not valid MessagePack
-- Throws [parse_error.113](../../home/exceptions.md#jsonexceptionparse_error113) if a string was expected as map key,
-  but not found
-
-## Complexity
-
-Linear in the size of the input.
-
-## Examples
-
-??? example
-
-    The example shows the deserialization of a byte vector in MessagePack format to a JSON value.
-     
-    ```cpp
-    --8<-- "examples/from_msgpack.cpp"
-    ```
-    
-    Output:
-    
-    ```json
-    --8<-- "examples/from_msgpack.output"
-    ```
-
-## Version history
-
-- Added in version 2.0.9.
-- Parameter `start_index` since version 2.1.1.
-- Changed to consume input adapters, removed `start_index` parameter, and added `strict` parameter in version 3.0.0.
-- Added `allow_exceptions` parameter in version 3.2.0.

-## Requirements
-
-The class satisfies the following concept requirements:
-
-### Basic
-
-- [DefaultConstructible](https://en.cppreference.com/w/cpp/named_req/DefaultConstructible): JSON values can be default
-  constructed. The result will be a JSON null value.
-- [MoveConstructible](https://en.cppreference.com/w/cpp/named_req/MoveConstructible): A JSON value can be constructed
-  from an rvalue argument.
-- [CopyConstructible](https://en.cppreference.com/w/cpp/named_req/CopyConstructible): A JSON value can be
-  copy-constructed from an lvalue expression.
-- [MoveAssignable](https://en.cppreference.com/w/cpp/named_req/MoveAssignable): A JSON value van be assigned from an
-  rvalue argument.
-- [CopyAssignable](https://en.cppreference.com/w/cpp/named_req/CopyAssignable): A JSON value can be copy-assigned from
-  an lvalue expression.
-- [Destructible](https://en.cppreference.com/w/cpp/named_req/Destructible): JSON values can be destructed.
-
-### Layout
-
-- [StandardLayoutType](https://en.cppreference.com/w/cpp/named_req/StandardLayoutType): JSON values have
-  [standard layout](https://en.cppreference.com/w/cpp/language/data_members#Standard_layout): All non-static data
-  members are private and standard layout types, the class has no virtual functions or (virtual) base classes.
-
-### Library-wide
-
-- [EqualityComparable](https://en.cppreference.com/w/cpp/named_req/EqualityComparable): JSON values can be compared with
-  `==`, see [`operator==`](operator_eq.md).
-- [LessThanComparable](https://en.cppreference.com/w/cpp/named_req/LessThanComparable): JSON values can be compared with
-  `<`, see [`operator<`](operator_le).
-- [Swappable](https://en.cppreference.com/w/cpp/named_req/Swappable): Any JSON lvalue or rvalue of can be swapped with
-  any lvalue or rvalue of other compatible types, using unqualified function `swap`.
-- [NullablePointer](https://en.cppreference.com/w/cpp/named_req/NullablePointer): JSON values can be compared against
-  `std::nullptr_t` objects which are used to model the `null` value.
-
-### Container
-
-- [Container](https://en.cppreference.com/w/cpp/named_req/Container): JSON values can be used like STL containers and
-  provide iterator access.
-- [ReversibleContainer](https://en.cppreference.com/w/cpp/named_req/ReversibleContainer): JSON values can be used like
-  STL containers and provide reverse iterator access.

-# <small>nlohmann::basic_json::</small>is_discarded
-
-```cpp
-constexpr bool is_discarded() const noexcept;
-```
-
-This function returns `#!cpp true` for a JSON value if either:
-
-- the value was discarded during parsing with a callback function (see [`parser_callback_t`](parser_callback_t.md)), or
-- the value is the result of parsing invalid JSON with parameter `allow_exceptions` set to `#!cpp false`; see
-  [`parse`](parse.md) for more information.
-
-## Return value
-
-`#!cpp true` if type is discarded, `#!cpp false` otherwise.
-
-## Exception safety
-
-No-throw guarantee: this member function never throws exceptions.
-
-## Complexity
-
-Constant.
-
-## Notes
-
-!!! note
-
-    Discarded values are never compared equal with [`operator==`](operator_eq.md). That is, checking whether a JSON
-    value `j` is discarded will only work via:
-    
-    ```cpp
-    j.is_discarded()
-    ```
-    
-    because
-    
-    ```cpp
-    j == json::value_t::discarded
-    ```
-    
-    will always be `#!cpp false`.
-
-!!! note
-
-    When a value is discarded by a callback function (see [`parser_callback_t`](parser_callback_t.md)) during parsing,
-    then it is removed when it is part of a structured value. For instance, if the second value of an array is discared,
-    instead of `#!json [null, discarded, false]`, the array `#!json [null, false]` is returned. Only if the top-level
-    value is discarded, the return value of the `parse` call is discarded.
-
-This function will always be `#!cpp false` for JSON values after parsing. That is, discarded values can only occur
-during parsing, but will be removed when inside a structured value or replaced by null in other cases.

-```cpp
-constexpr bool is_primitive() const noexcept;
-```
-
-This function returns `#!cpp true` if and only if the JSON type is primitive (string, number, boolean, `#!json null`,
-binary).
-    
-## Return value
-
-`#!cpp true` if type is primitive (string, number, boolean, `#!json null`, or binary), `#!cpp false` otherwise.
-
-## Exception safety
-
-No-throw guarantee: this member function never throws exceptions.
-
-## Complexity
-

-
-## Possible implementation
-
-```cpp
-constexpr bool is_primitive() const noexcept
-{
-    return is_null() || is_string() || is_boolean() || is_number() || is_binary();
-}
-```
-
-## Notes
-
-The term *primitive* stems from [RFC 8259](https://tools.ietf.org/html/rfc8259):
-
-> JSON can represent four primitive types (strings, numbers, booleans, and null) and two structured types (objects and
-> arrays).
-
-This library extends primitive types to binary types, because binary types are  roughly comparable to strings. Hence,
-`is_primitive()` returns `#!cpp true` for binary values.
-
-## Examples
-
-??? example
-
-    The following code exemplifies `is_primitive()` for all JSON types.
-    
-    ```cpp
-    --8<-- "examples/is_primitive.cpp"

-
-The merge patch format is primarily intended for use with the HTTP PATCH method as a means of describing a set of

-
-The function implements the following algorithm from Section 2 of

-
-```python
-define MergePatch(Target, Patch):

-
-```cpp

-
-The type used to store JSON numbers (floating-point).
-
-[RFC 8259](https://tools.ietf.org/html/rfc8259) describes numbers as follows:
-> The representation of numbers is similar to that used in most programming languages. A number is represented in base
-> 10 using decimal digits. It contains an integer component that may be prefixed with an optional minus sign, which may
-> be followed by a fraction part and/or an exponent part. Leading zeros are not allowed. (...) Numeric values that
-> cannot be represented in the grammar below (such as Infinity and NaN) are not permitted.
-
-This description includes both integer and floating-point numbers. However, C++ allows more precise storage if it is
-known whether the number is a signed integer, an unsigned integer or a floating-point number. Therefore, three different
-types, [`number_integer_t`](number_integer_t.md), [`number_unsigned_t`](number_unsigned_t.md) and `number_float_t` are
-used.
-
-To store floating-point numbers in C++, a type is defined by the template parameter `NumberFloatType` which chooses the
-type to use.
-
-## Notes
-
-#### Default type
-
-With the default values for `NumberFloatType` (`double`), the default value for `number_float_t` is `#!cpp double`.
-
-#### Default behavior
-
-- The restrictions about leading zeros is not enforced in C++. Instead, leading zeros in floating-point literals will be
-  ignored. Internally, the value will be stored as decimal number. For instance, the C++ floating-point literal `01.2`
-  will be serialized to `1.2`. During deserialization, leading zeros yield an error.
-- Not-a-number (NaN) values will be serialized to `null`.
-
-#### Limits
-
-[RFC 8259](https://tools.ietf.org/html/rfc8259) states:
-> This specification allows implementations to set limits on the range and precision of numbers accepted. Since software
-> that implements IEEE 754-2008 binary64 (double precision) numbers is generally available and widely used, good
-> interoperability can be achieved by implementations that expect no more precision or range than these provide, in the
-> sense that implementations will approximate JSON numbers within the expected precision.
-
-This implementation does exactly follow this approach, as it uses double precision floating-point numbers. Note values
-smaller than `-1.79769313486232e+308` and values greater than `1.79769313486232e+308` will be stored as NaN internally
-and be serialized to `null`.
-
-#### Storage
-
-Floating-point number values are stored directly inside a `basic_json` type.
-
-## Examples

-??? example
-
-    The following code shows that `number_float_t` is by default, a typedef to `#!cpp double`.

-# <small>nlohmann::basic_json::</small>number_integer_t
-
-```cpp
-using number_integer_t = NumberIntegerType;
-```
-
-The type used to store JSON numbers (integers).
-
-[RFC 8259](https://tools.ietf.org/html/rfc8259) describes numbers as follows:
-> The representation of numbers is similar to that used in most programming languages. A number is represented in base
-> 10 using decimal digits. It contains an integer component that may be prefixed with an optional minus sign, which may
-> be followed by a fraction part and/or an exponent part. Leading zeros are not allowed. (...) Numeric values that
-> cannot be represented in the grammar below (such as Infinity and NaN) are not permitted.
-
-This description includes both integer and floating-point numbers. However, C++ allows more precise storage if it is
-known whether the number is a signed integer, an unsigned integer or a floating-point number. Therefore, three different
-types, `number_integer_t`,  [`number_unsigned_t`](number_unsigned_t.md) and [`number_float_t`](number_float_t.md) are
-used.
-
-To store integer numbers in C++, a type is defined by the template parameter `NumberIntegerType` which chooses the type
-to use.
-
-## Notes
-
-#### Default type
-
-With the default values for `NumberIntegerType` (`std::int64_t`), the default value for `number_integer_t` is
-`#!cpp std::int64_t`.
-
-#### Default behavior
-
-- The restrictions about leading zeros is not enforced in C++. Instead, leading zeros in integer literals lead to an
-  interpretation as octal number. Internally, the value will be stored as decimal number. For instance, the C++ integer
-  literal `010` will be serialized to `8`. During deserialization, leading zeros yield an error.
-- Not-a-number (NaN) values will be serialized to `null`.
-
-#### Limits
-
-[RFC 8259](https://tools.ietf.org/html/rfc8259) specifies:
-> An implementation may set limits on the range and precision of numbers.
-
-When the default type is used, the maximal integer number that can be stored is `9223372036854775807` (INT64_MAX) and
-the minimal integer number that can be stored is `-9223372036854775808` (INT64_MIN). Integer numbers that are out of
-range will yield over/underflow when used in a constructor. During deserialization, too large or small integer numbers
-will be automatically be stored as [`number_unsigned_t`](number_unsigned_t.md) or [`number_float_t`](number_float_t.md).
-
-[RFC 8259](https://tools.ietf.org/html/rfc8259) further states:
-> Note that when such software is used, numbers that are integers and are in the range $[-2^{53}+1, 2^{53}-1]$ are
-> interoperable in the sense that implementations will agree exactly on their numeric values.
-
-As this range is a subrange of the exactly supported range [INT64_MIN, INT64_MAX], this class's integer type is
-interoperable.
-
-#### Storage
-
-Integer number values are stored directly inside a `basic_json` type.

-# <small>nlohmann::basic_json::</small>object
-
-```cpp
-static basic_json object(initializer_list_t init = {});
-```
-
-Creates a JSON object value from a given initializer list. The initializer lists elements must be pairs, and their first
-elements must be strings. If the initializer list is empty, the empty object `#!json {}` is created.
-
-## Parameters
-
-`init` (in)
-:   initializer list with JSON values to create an object from (optional)
-
-## Return value
-
-JSON object value
-
-## Exception safety
-
-Strong guarantee: if an exception is thrown, there are no changes in the JSON value.
-
-## Exceptions
-
-Throws [`type_error.301`](../../home/exceptions.md#jsonexceptiontype_error301) if `init` is not a list of pairs whose
-first elements are strings. In this case, no object can be created. When such a value is passed to
-`basic_json(initializer_list_t, bool, value_t)`, an array would have been created from the passed initializer list
-`init`. See example below.
-
-## Complexity
-
-Linear in the size of `init`.
-
-## Notes
-
-This function is only added for symmetry reasons. In contrast to the related function `array(initializer_list_t)`, there
-are no cases which can only be expressed by this function. That is, any initializer list `init` can also be passed to
-the initializer list constructor `basic_json(initializer_list_t, bool, value_t)`.

-```
-
-The type used to store JSON objects.
-
-[RFC 8259](https://tools.ietf.org/html/rfc8259) describes JSON objects as follows:
-> An object is an unordered collection of zero or more name/value pairs, where a name is a string and a value is a
-> string, number, boolean, null, object, or array.
-
-To store objects in C++, a type is defined by the template parameters described below.
-
-## Template parameters
-
-`ObjectType`
-:   the container to store objects (e.g., `std::map` or `std::unordered_map`)
-
-`StringType`
-:   the type of the keys or names (e.g., `std::string`). The comparison function `std::less<StringType>` is used to
-    order elements inside the container.
-
-`AllocatorType`
-:   the allocator to use for objects (e.g., `std::allocator`)
-
-## Notes
-
-#### Default type
-
-With the default values for `ObjectType` (`std::map`), `StringType` (`std::string`), and `AllocatorType`
-(`std::allocator`), the default value for `object_t` is:
-
-```cpp
-// until C++14
-std::map<
-  std::string, // key_type
-  basic_json, // value_type
-  std::less<std::string>, // key_compare
-  std::allocator<std::pair<const std::string, basic_json>> // allocator_type
->
-
-// since C++14
-std::map<
-  std::string, // key_type
-  basic_json, // value_type
-  std::less<>, // key_compare
-  std::allocator<std::pair<const std::string, basic_json>> // allocator_type
->
-```
-
-See [`object_comparator_t`](object_comparator_t.md) for more information.
-
-#### Behavior
-
-The choice of `object_t` influences the behavior of the JSON class. With the default type, objects have the following
-behavior:
-
-- When all names are unique, objects will be interoperable in the sense that all software implementations receiving that
-  object will agree on the name-value mappings.
-- When the names within an object are not unique, it is unspecified which one of the values for a given key will be
-  chosen. For instance, `#!json {"key": 2, "key": 1}` could be equal to either `#!json {"key": 1}` or
-  `#!json {"key": 2}`.
-- Internally, name/value pairs are stored in lexicographical order of the names. Objects will also be serialized (see
-  [`dump`](dump.md)) in this order. For instance, `#!json {"b": 1, "a": 2}` and `#!json {"a": 2, "b": 1}` will be stored
-  and serialized as `#!json {"a": 2, "b": 1}`.
-- When comparing objects, the order of the name/value pairs is irrelevant. This makes objects interoperable in the sense
-  that they will not be affected by these differences. For instance, `#!json {"b": 1, "a": 2}` and
-  `#!json {"a": 2, "b": 1}` will be treated as equal.
-
-#### Limits
-
-[RFC 8259](https://tools.ietf.org/html/rfc8259) specifies:
-> An implementation may set limits on the maximum depth of nesting.
-
-In this class, the object's limit of nesting is not explicitly constrained. However, a maximum depth of nesting may be
-introduced by the compiler or runtime environment. A theoretical limit can be queried by calling the
-[`max_size`](max_size.md) function of a JSON object.
-
-#### Storage
-
-Objects are stored as pointers in a `basic_json` type. That is, for any access to object values, a pointer of type
-`object_t*` must be dereferenced.
-
-#### Object key order
-
-The order name/value pairs are added to the object is *not* preserved by the library. Therefore, iterating an object may
-return name/value pairs in a different order than they were originally stored. In fact, keys will be traversed in
-alphabetical order as `std::map` with `std::less` is used by default. Please note this behavior conforms to
-[RFC 8259](https://tools.ietf.org/html/rfc8259), because any order implements the specified "unordered" nature of JSON objects.

-1. reference to the element at index `idx`
-2. reference to the element at key `key`
-3. reference to the element pointed to by `ptr`
-
-## Exception safety
-
-Strong exception safety: if an exception occurs, the original value stays intact.
-
-## Exceptions
-
-1. The function can throw the following exceptions:
-    - Throws [`type_error.305`](../../home/exceptions.md#jsonexceptiontype_error305) if the JSON value is not an array
-      or null; in that case, using the `[]` operator with an index makes no sense.
-2. The function can throw the following exceptions:
-    - Throws [`type_error.305`](../../home/exceptions.md#jsonexceptiontype_error305) if the JSON value is not an object
-      or null; in that case, using the `[]` operator with a key makes no sense.
-3. The function can throw the following exceptions:
-    - Throws [`parse_error.106`](../../home/exceptions.md#jsonexceptionparse_error106) if an array index in the passed
-      JSON pointer `ptr` begins with '0'.
-    - Throws [`parse_error.109`](../../home/exceptions.md#jsonexceptionparse_error109) if an array index in the passed
-      JSON pointer `ptr` is not a number.
-    - Throws [`out_of_range.402`](../../home/exceptions.md#jsonexceptionout_of_range402) if the array index '-' is used
-      in the passed JSON pointer `ptr` for the const version.
-    - Throws [`out_of_range.404`](../../home/exceptions.md#jsonexceptionout_of_range404) if the JSON pointer `ptr` can
-      not be resolved.
-
-## Complexity
-
-1. Constant if `idx` is in the range of the array. Otherwise, linear in `idx - size()`.
-2. Logarithmic in the size of the container.
-3. Constant
-
-## Notes
-
-!!! danger
-
-    1. If the element with key `idx` does not exist, the behavior is undefined.
-    2. If the element with key `key` does not exist, the behavior is undefined and is **guarded by an assertion**!
-
-1. The non-const version may add values: If `idx` is beyond the range of the array (i.e., `idx >= size()`), then the
-   array is silently filled up with `#!json null` values to make `idx` a valid reference to the last stored element. In
-   case the value was `#!json null` before, it is converted to an array.
-
-2. If `key` is not found in the object, then it is silently added to the object and filled with a `#!json null` value to
-   make `key` a valid reference. In case the value was `#!json null` before, it is converted to an object.
-
-3. `null` values are created in arrays and objects if necessary.
-   
-    In particular:
-
-    - If the JSON pointer points to an object key that does not exist, it is created and filled with a `#!json null`
-      value before a reference to it is returned.
-    - If the JSON pointer points to an array index that does not exist, it is created and filled with a `#!json null`
-      value before a reference to it is returned. All indices between the current maximum and the given index are also
-      filled with `#!json null`.
-    - The special value `-` is treated as a synonym for the index past the end.
-

-# <small>nlohmann::basic_json::</small>operator ValueType
-
-```cpp
-template<typename ValueType>
-JSON_EXPLICIT operator ValueType() const;
-```
-
-Implicit type conversion between the JSON value and a compatible value. The call is realized by calling
-[`get()`](get.md). See [Notes](#notes) for the meaning of `JSON_EXPLICIT`.
-
-## Template parameters
-
-`ValueType`
-:   the value type to return
-
-## Return value
-
-copy of the JSON value, converted to `ValueType`
-
-## Exceptions
-
-Depends on what `json_serializer<ValueType>` `from_json()` method throws
-
-## Complexity
-
-Linear in the size of the JSON value.
-
-## Notes
-
-By default `JSON_EXPLICIT` defined to the empty string, so the signature is:
-
-```cpp
-template<typename ValueType>
-operator ValueType() const;
-```
-
-If [`JSON_USE_IMPLICIT_CONVERSIONS`](../../features/macros.md#json_use_implicit_conversions) is set to `0`,
-`JSON_EXPLICIT` is defined to `#!cpp explicit`:
-
-```cpp
-template<typename ValueType>
-explicit operator ValueType() const;
-```
-
-That is, implicit conversions can be switched off by defining
-[`JSON_USE_IMPLICIT_CONVERSIONS`](../../features/macros.md#json_use_implicit_conversions) to `0`.
-
-## Examples
-
-??? example
-
-    The example below shows several conversions from JSON values
-    to other types. There a few things to note: (1) Floating-point numbers can
-    be converted to integers, (2) A JSON array can be converted to a standard
-    `std::vector<short>`, (3) A JSON object can be converted to C++
-    associative containers such as `std::unordered_map<std::string, json>`.
-        
-    ```cpp

-Compares two JSON values for equality according to the following rules:
-
-- Two JSON values are equal if (1) they are not discarded, (2) they are from the same type, and (3) their stored values
-  are the same according to their respective `operator==`.
-- Integer and floating-point numbers are automatically converted before comparison. Note that two NaN values are always
-  treated as unequal.
-
-## Template parameters

-
-## Parameters
-
-`lhs` (in)
-:   first value to consider

-## Notes
-
-!!! note
-
-    - NaN values never compare equal to themselves or to other NaN values.
-    - JSON `#!cpp null` values are all equal.
-    - Discarded values never compare equal to themselves.
-
-!!! note
-
-    Floating-point numbers inside JSON values numbers are compared with `json::number_float_t::operator==` which is
-    `double::operator==` by default. To compare floating-point while respecting an epsilon, an alternative
-    [comparison function](https://github.com/mariokonrad/marnav/blob/master/include/marnav/math/floatingpoint.hpp#L34-#L39)
-    could be used, for instance
-    
-    ```cpp
-    template<typename T, typename = typename std::enable_if<std::is_floating_point<T>::value, T>::type>
-    inline bool is_same(T a, T b, T epsilon = std::numeric_limits<T>::epsilon()) noexcept
-    {
-        return std::abs(a - b) <= epsilon;
-    }
-    ```
-    
-    Or you can self-defined operator equal function like this:
-    
-    ```cpp
-    bool my_equal(const_reference lhs, const_reference rhs)
-    {
-        const auto lhs_type lhs.type();
-        const auto rhs_type rhs.type();
-        if (lhs_type == rhs_type)
-        {
-            switch(lhs_type)
-                // self_defined case
-                case value_t::number_float:
-                    return std::abs(lhs - rhs) <= std::numeric_limits<float>::epsilon();
-                // other cases remain the same with the original
-                ...

-Compares whether one JSON value `lhs` is less than another JSON value `rhs` according to the following rules:
-
-- If `lhs` and `rhs` have the same type, the values are compared using the default `<` operator.
-- Integer and floating-point numbers are automatically converted before comparison
-- Discarded values a
-- In case `lhs` and `rhs` have different types, the values are ignored and the order of the types is considered, which

-```
-
-Serialize the given JSON value `j` to the output stream `o`. The JSON value will be serialized using the
-[`dump`](dump.md) member function.
-
-- The indentation of the output can be controlled with the member variable `width` of the output stream `o`. For
-  instance, using the manipulator `std::setw(4)` on `o` sets the indentation level to `4` and the serialization result
-  is the same as calling `dump(4)`.
-- The indentation character can be controlled with the member variable `fill` of the output stream `o`. For instance,
-  the manipulator `std::setfill('\\t')` sets indentation to use a tab character rather than the default space character.
-
-## Parameters
-
-`o` (in, out)
-:   stream to serialize to
-
-`j` (in)
-:   JSON value to serialize
-
-## Return value
-
-the stream `o`
-
-## Exceptions
-
-Throws [`type_error.316`](../../home/exceptions.md#jsonexceptiontype_error316) if a string stored inside the JSON value
-is not UTF-8 encoded. Note that unlike the [`dump`](dump.md) member functions, no `error_handler` can be set.

-1. Deserialize from a compatible input.
-2. Deserialize from a pair of character iterators
-    
-    The `value_type` of the iterator must be an integral type with size of 1, 2 or 4 bytes, which will be interpreted
-    respectively as UTF-8, UTF-16 and UTF-32.
-
-## Template parameters
-
-`InputType`
-:   A compatible input, for instance:
-    
-    - an `std::istream` object
-    - a `FILE` pointer
-    - a C-style array of characters
-    - a pointer to a null-terminated string of single byte characters
-    - an object `obj` for which `begin(obj)` and `end(obj)` produces a valid pair of iterators.
-
-`IteratorType`
-:   a compatible iterator type, for instance.
-
-    - a pair of `std::string::iterator` or `std::vector<std::uint8_t>::iterator`
-    - a pair of pointers such as `ptr` and `ptr + len`
-
-## Parameters
-
-`i` (in)
-:   Input to parse from.
-
-`cb` (in)
-:   a parser callback function of type [`parser_callback_t`](parser_callback_t.md) which is used to control the
-    deserialization by filtering unwanted values (optional)
-
-`allow_exceptions` (in)
-:    whether to throw exceptions in case of a parse error (optional, `#!cpp true` by default)
-
-`ignore_comments` (in)
-:   whether comments should be ignored and treated like whitespace (`#!cpp true`) or yield a parse error
-    (`#!cpp false`); (optional, `#!cpp false` by default)
-
-`first` (in)
-:   iterator to start of character range
-
-`last` (in)
-:   iterator to end of character range
-
-## Return value
-
-Deserialized JSON value; in case of a parse error and `allow_exceptions` set to `#!cpp false`, the return value will be
-`value_t::discarded`. The latter can be checked with [`is_discarded`](is_discarded.md).
-
-## Exception safety
-
-Strong guarantee: if an exception is thrown, there are no changes in the JSON value.
-
-## Complexity
-
-Linear in the length of the input. The parser is a predictive LL(1) parser. The complexity can be higher if the parser
-callback function `cb` or reading from (1) the input `i` or (2) the iterator range [`first`, `last`] has a
-super-linear complexity.
-
-## Notes
-
-(1) A UTF-8 byte order mark is silently ignored.

-```cpp
-template<typename BasicJsonType>
-using parser_callback_t =
-    std::function<bool(int depth, parse_event_t event, BasicJsonType& parsed)>;
-```
-
-With a parser callback function, the result of parsing a JSON text can be influenced. When passed to
-[`parse`](parse.md), it is called on certain events (passed as [`parse_event_t`](parse_event_t.md) via parameter
-`event`) with a set recursion depth `depth` and context JSON value `parsed`. The return value of the callback function
-is a boolean indicating whether the element that emitted the callback shall be kept or not.
-
-We distinguish six scenarios (determined by the event type) in which the callback function can be called. The following
-table describes the values of the parameters `depth`, `event`, and `parsed`.
-
-| parameter `event`             | description                                               | parameter `depth`                         | parameter `parsed`               |
-|-------------------------------|-----------------------------------------------------------|-------------------------------------------|----------------------------------|
-| `parse_event_t::object_start` | the parser read `{` and started to process a JSON object  | depth of the parent of the JSON object    | a JSON value with type discarded |
-| `parse_event_t::key`          | the parser read a key of a value in an object             | depth of the currently parsed JSON object | a JSON string containing the key |
-| `parse_event_t::object_end`   | the parser read `}` and finished processing a JSON object | depth of the parent of the JSON object    | the parsed JSON object           |
-| `parse_event_t::array_start`  | the parser read `[` and started to process a JSON array   | depth of the parent of the JSON array     | a JSON value with type discarded |
-| `parse_event_t::array_end`    | the parser read `]` and finished processing a JSON array  | depth of the parent of the JSON array     | the parsed JSON array            |
-| `parse_event_t::value`        | the parser finished reading a JSON value                  | depth of the value                        | the parsed JSON value            |
-
-![Example when certain parse events are triggered](../../images/callback_events.png)
-
-Discarding a value (i.e., returning `#!cpp false`) has different effects depending on the context in which function was
-called:
-
-- Discarded values in structured types are skipped. That is, the parser will behave as if the discarded value was never
-  read.
-- In case a value outside a structured type is skipped, it is replaced with `null`. This case happens if the top-level
-  element is skipped.
-
-## Parameters
-
-`depth` (in)
-:   the depth of the recursion during parsing
-
-`event` (in)
-:   an event of type [`parse_event_t`](parse_event_t.md) indicating the context in
-    the callback function has been called
-
-`parsed` (in, out)
-:    the current intermediate parse result; note that
-     writing to this value has no effect for `parse_event_t::key` events
-
-## Return value
-
-Whether the JSON value which called the function during parsing should be kept (`#!cpp true`) or not (`#!cpp false`). In
-the latter case, it is either skipped completely or replaced by an empty discarded object.
-
-## Examples
-
-??? example
-
-    The example below demonstrates the `parse()` function with
-    and without callback function.

-# <small>nlohmann::basic_json::</small>patch
-
-```cpp
-basic_json patch(const basic_json& json_patch) const;
-```
-
-[JSON Patch](http://jsonpatch.com) defines a JSON document structure for expressing a sequence of operations to apply to
-a JSON document. With this function, a JSON Patch is applied to the current JSON value by executing all operations from
-the patch.
-
-## Parameters
-
-`json_patch` (in)
-:   JSON patch document
-
-## Return value
-
-patched document
-
-## Exception safety
-
-Strong guarantee: if an exception is thrown, there are no changes in the JSON value.
-
-## Exceptions
-
-- Throws [`parse_error.104`](../../home/exceptions.md#jsonexceptionparse_error104) if the JSON patch does not consist of
-  an array of objects.
-- Throws [`parse_error.105`](../../home/exceptions.md#jsonexceptionparse_error105) if the JSON patch is malformed (e.g.,
-  mandatory attributes are missing); example: `"operation add must have member path"`.
-- Throws [`out_of_range.401`](../../home/exceptions.md#jsonexceptionout_of_range401) if an array index is out of range.
-- Throws [`out_of_range.403`](../../home/exceptions.md#jsonexceptionout_of_range403) if a JSON pointer inside the patch
-  could not be resolved successfully in the current JSON value; example: `"key baz not found"`.
-- Throws [`out_of_range.405`](../../home/exceptions.md#jsonexceptionout_of_range405) if JSON pointer has no parent
-  ("add", "remove", "move")
-- Throws [`out_of_range.501`](../../home/exceptions.md#jsonexceptionother_error501) if "test" operation was
-  unsuccessful.
-
-## Complexity
-
-Linear in the size of the JSON value and the length of the JSON patch. As usually only a fraction of the JSON value is
-affected by the patch, the complexity can usually be neglected.
-
-## Notes
-
-The application of a patch is atomic: Either all operations succeed and the patched document is returned or an exception
-is thrown. In any case, the original value is not changed: the patch is applied to a copy of the value.
-
-## Examples
-
-??? example
-
-    The following code shows how a JSON patch is applied to a value.
-     
-    ```cpp
-    --8<-- "examples/patch.cpp"

-
-// (2)
-void push_back(const typename object_t::value_type& val);
-
-// (3)
-void push_back(initializer_list_t init);
-```
-
-1. Appends the given element `val` to the end of the JSON array. If the function is called on a JSON null value, an
-   empty array is created before appending `val`.
-
-2. Inserts the given element `val` to the JSON object. If the function is called on a JSON null value, an empty object
-   is created before inserting `val`.
-
-3. This function allows using `push_back` with an initializer list. In case
-
-    1. the current value is an object,
-    2. the initializer list `init` contains only two elements, and
-    3. the first element of `init` is a string,
-
-    `init` is converted into an object element and added using `push_back(const typename object_t::value_type&)`.
-    Otherwise, `init` is converted to a JSON value and added using `push_back(basic_json&&)`.
-
-## Parameters
-
-`val` (in)
-:   the value to add to the JSON array/object
-
-`init` (in)
-:   an initializer list
-
-## Exceptions
-
-1. The function can throw the following exceptions:
-    - Throws [`type_error.308`](../../home/exceptions.md#jsonexceptiontype_error308) when called on a type other than
-      JSON array or null; example: `"cannot use push_back() with number"`
-2. The function can throw the following exceptions:

-      JSON object or null; example: `"cannot use push_back() with number"`
-
-## Complexity
-
-1. Amortized constant.
-2. Logarithmic in the size of the container, O(log(`size()`)).
-3. Linear in the size of the initializer list `init`.
-
-## Notes
-
-(3) This function is required to resolve an ambiguous overload error, because pairs like `{"key", "value"}` can be both
-    interpreted as `object_t::value_type` or `std::initializer_list<basic_json>`, see
-    [#235](https://github.com/nlohmann/json/issues/235) for more information.

-    
-    The value_type of the iterator must be an integral type with size of 1, 2 or 4 bytes, which will be interpreted
-    respectively as UTF-8, UTF-16 and UTF-32.
-
-The SAX event lister must follow the interface of [`json_sax`](../json_sax/index.md).
-
-## Template parameters
-
-`InputType`
-:   A compatible input, for instance:
-    
-    - an `std::istream` object
-    - a `FILE` pointer
-    - a C-style array of characters
-    - a pointer to a null-terminated string of single byte characters
-    - an object `obj` for which `begin(obj)` and `end(obj)` produces a valid pair of
-      iterators.
-
-`IteratorType`
-:   Description
-
-`SAX`
-:   Description
-
-## Parameters
-
-`i` (in)
-:   Input to parse from.
-
-`sax` (in)
-:   SAX event listener
-
-`format` (in)
-:    the format to parse (JSON, CBOR, MessagePack, or UBJSON) (optional, `input_format_t::json` by default), see
-     [`input_format_t`](input_format_t.md) for more information
-
-`strict` (in)
-:   whether the input has to be consumed completely (optional, `#!cpp true` by default)
-
-`ignore_comments` (in)
-:   whether comments should be ignored and treated like whitespace (`#!cpp true`) or yield a parse error
-    (`#!cpp false`); (optional, `#!cpp false` by default)
-
-`first` (in)
-:   iterator to start of character range
-
-`last` (in)
-:   iterator to end of character range
-
-## Return value
-
-return value of the last processed SAX event
-
-## Exception safety
-
-## Complexity
-
-Linear in the length of the input. The parser is a predictive LL(1) parser. The complexity can be higher if the SAX
-consumer `sax` has a super-linear complexity.
-
-## Notes
-
-A UTF-8 byte order mark is silently ignored.
-
-## Examples
-
-??? example
-
-    The example below demonstrates the `sax_parse()` function reading from string and processing the events with a
-    user-defined SAX event consumer.
-    
-    ```cpp

-!!! warning "Deprecation"
-
-    Overload (2) replaces calls to `sax_parse` with a pair of iterators as their first parameter which has been
-    deprecated in version 3.8.0. This overload will be removed in version 4.0.0. Please replace all calls like

-```cpp
-namespace std {
-    struct hash<nlohmann::basic_json>;
-}
-```
-
-Return a hash value for a JSON object. The hash function tries to rely on `std::hash` where possible. Furthermore, the
-type of the JSON value is taken into account to have different hash values for `#!json null`, `#!cpp 0`, `#!cpp 0U`, and
-`#!cpp false`, etc.
-
-## Examples
-
-??? example
-
-    The example shows how to calculate hash values for different JSON values.
-     
-    ```cpp
-    --8<-- "examples/std_hash.cpp"
-    ```
-    
-    Output:
-    
-    ```json
-    --8<-- "examples/std_hash.output"

-# <small>nlohmann::basic_json::</small>string_t
-
-```cpp
-using string_t = StringType;
-```
-
-The type used to store JSON strings.
-
-[RFC 8259](https://tools.ietf.org/html/rfc8259) describes JSON strings as follows:
-> A string is a sequence of zero or more Unicode characters.
-
-To store objects in C++, a type is defined by the template parameter described below. Unicode values are split by the
-JSON class into byte-sized characters during deserialization.
-
-## Template parameters
-
-`StringType`
-:   the container to store strings (e.g., `std::string`). Note this container is used for keys/names in objects, see
-    [object_t](object_t.md).
-
-## Notes
-
-#### Default type
-
-With the default values for `StringType` (`std::string`), the default value for `string_t` is `#!cpp std::string`.
-
-#### Encoding
-
-Strings are stored in UTF-8 encoding. Therefore, functions like `std::string::size()` or `std::string::length()` return
-the number of bytes in the string rather than the number of characters or glyphs.
-
-#### String comparison
-
-[RFC 8259](https://tools.ietf.org/html/rfc8259) states:
-> Software implementations are typically required to test names of object members for equality. Implementations that
-> transform the textual representation into sequences of Unicode code units and then perform the comparison numerically,
-> code unit by code unit, are interoperable in the sense that implementations will agree in all cases on equality or
-> inequality of two strings. For example, implementations that compare strings with escaped characters unconverted may
-> incorrectly find that `"a\\b"` and `"a\u005Cb"` are not equal.
-
-This implementation is interoperable as it does compare strings code unit by code unit.
-
-#### Storage
-
-String values are stored as pointers in a `basic_json` type. That is, for any access to string values, a pointer of type
-`string_t*` must be dereferenced.
-
-## Examples
-
-??? example
-
-    The following code shows that `string_t` is by default, a typedef to `#!cpp std::string`.
-     
-    ```cpp
-    --8<-- "examples/string_t.cpp"
-    ```
-    
-    Output:
-    
-    ```json
-    --8<-- "examples/string_t.output"

-# <small>nlohmann::basic_json::</small>unflatten
-
-```cpp
-basic_json unflatten() const;
-```
-
-The function restores the arbitrary nesting of a JSON value that has been flattened before using the
-[`flatten()`](flatten.md) function. The JSON value must meet certain constraints:
-
-1. The value must be an object.
-2. The keys must be JSON pointers (see [RFC 6901](https://tools.ietf.org/html/rfc6901))
-3. The mapped values must be primitive JSON types.
-    
-## Return value
-
-the original JSON from a flattened version
-
-## Exception safety
-
-Strong exception safety: if an exception occurs, the original value stays intact.
-
-## Exceptions
-
-The function can throw the following exceptions:
-
-- Throws [`type_error.314`](../../home/exceptions.md#jsonexceptiontype_error314) if value is not an object
-- Throws [`type_error.315`](../../home/exceptions.md#jsonexceptiontype_error315) if object values are not primitive
-
-## Complexity
-
-Linear in the size the JSON value.
-
-## Notes
-
-Empty objects and arrays are flattened by [`flatten()`](flatten.md) to `#!json null` values and can not unflattened to
-their original type. Apart from this example, for a JSON value `j`, the following is always true:
-`#!cpp j == j.flatten().unflatten()`.

-
-1. Inserts all values from JSON object `j`.
-2. Inserts all values from range `[first, last)`
-
-When `merge_objects` is `#!c false` (default), existing keys are overwritten. When `merge_objects` is `#!c true`,

-
-The function is motivated by Python's [dict.update](https://docs.python.org/3.6/library/stdtypes.html#dict.update)
-function.
-
-## Parameters
-
-`j` (in)
-:   JSON object to read values from
-
-`merge_objects` (in)
-:   when `#!c true`, existing keys are not overwritten, but contents of objects are merged recursively (default:
-    `#!c false`)

-    ```
-
-??? example
-
-    One common usecase for this function is the handling of user settings. Assume your application can configured in
-    some aspects:
-
-    ```json
-    {
-        "color": "red",
-        "active": true,
-        "name": {"de": "Maus", "en": "mouse"}
-    }
-    ```
-
-    The user may override the default settings selectively:
-
-    ```json
-    {
-        "color": "blue",
-        "name": {"es": "ratón"},
-    }
-    ```
-
-    Then `update` manages the merging of default settings and user settings:
- 
-    ```cpp
-    auto user_settings = json::parse("config.json");
-    auto effective_settings = get_default_settings();
-    effective_settings.update(user_settings);
-    ```
-    
-    Now `effective_settings` contains the default settings, but those keys set by the user are overwritten:
-
-    ```json
-    {
-        "color": "blue",
-        "active": true,
-        "name": {"es": "ratón"}
-    }
-    ```
-
-    Note existing keys were just overwritten. To merge objects, `merge_objects` setting should be set to `#!c true`:
-    
-    ```cpp
-    auto user_settings = json::parse("config.json");
-    auto effective_settings = get_default_settings();
-    effective_settings.update(user_settings, true);
-    ```
-
-    ```json
-    {
-        "color": "blue",
-        "active": true,
-        "name": {"de": "Maus", "en": "mouse", "es": "ratón"}
-    }

-
-1. Returns either a copy of an object's element at the specified key `key` or a given default value if no element with
-   key `key` exists.
-   
-    The function is basically equivalent to executing

-
-!!! note
-
-    - Unlike [`at`](at.md), this function does not throw if the given `key`/`ptr` was not found.
-    - Unlike [`operator[]`](operator[].md), this function does not implicitly add an element to the position defined by
-     `key`/`ptr` key. This function is furthermore also applicable to const objects.
-
-## Template parameters
-
-`ValueType` 
-:   type compatible to JSON values, for instance `#!cpp int` for JSON integer numbers, `#!cpp bool` for JSON booleans,
-    or `#!cpp std::vector` types for JSON arrays. Note the type of the expected value at `key`/`ptr` and the default
-    value `default_value` must be compatible.
-
-## Parameters
-
-`key` (in)
-:   key of the element to access
-
-`default_value` (in)
-:   the value to return if key/ptr found no value
-
-`ptr` (in)
-:   a JSON pointer to the element to access
-
-## Return value
-
-1. copy of the element at key `key` or `default_value` if `key` is not found
-1. copy of the element at JSON Pointer `ptr` or `default_value` if no value for `ptr` is found
-
-## Exception safety
-
-Strong guarantee: if an exception is thrown, there are no
-changes to any JSON value.
-
-## Exceptions
-
-1. The function can throw the following exceptions:

-      the type of the value at `key`
-    - Throws [`type_error.306`](../../home/exceptions.md#jsonexceptiontype_error306) if the JSON value is not an object;
-      in that case, using `value()` with a key makes no sense.
-2. The function can throw the following exceptions:
-    - Throws [`type_error.302`](../../home/exceptions.md#jsonexceptiontype_error302) if `default_value` does not match

-# Arbitrary Types Conversions
-
-Every type can be serialized in JSON, not just STL containers and scalar types. Usually, you would do something along those lines:
-
-```cpp
-namespace ns {
-    // a simple struct to model a person
-    struct person {
-        std::string name;
-        std::string address;
-        int age;
-    };
-}
-
-ns::person p = {"Ned Flanders", "744 Evergreen Terrace", 60};
-
-// convert to JSON: copy each value into the JSON object
-json j;
-j["name"] = p.name;
-j["address"] = p.address;
-j["age"] = p.age;
-
-// ...
-
-// convert from JSON: copy each value from the JSON object
-ns::person p {
-    j["name"].get<std::string>(),
-    j["address"].get<std::string>(),
-    j["age"].get<int>()
-};
-```
-
-It works, but that's quite a lot of boilerplate... Fortunately, there's a better way:
-
-```cpp
-// create a person
-ns::person p {"Ned Flanders", "744 Evergreen Terrace", 60};
-
-// conversion: person -> json
-json j = p;
-
-std::cout << j << std::endl;
-// {"address":"744 Evergreen Terrace","age":60,"name":"Ned Flanders"}
-
-// conversion: json -> person
-auto p2 = j.get<ns::person>();
-
-// that's it
-assert(p == p2);
-```
-
-## Basic usage
-
-To make this work with one of your types, you only need to provide two functions:
-
-```cpp
-using json = nlohmann::json;
-
-namespace ns {
-    void to_json(json& j, const person& p) {
-        j = json{ {"name", p.name}, {"address", p.address}, {"age", p.age} };
-    }
-
-    void from_json(const json& j, person& p) {
-        j.at("name").get_to(p.name);
-        j.at("address").get_to(p.address);
-        j.at("age").get_to(p.age);
-    }
-} // namespace ns
-```
-
-That's all! When calling the `json` constructor with your type, your custom `to_json` method will be automatically called.
-Likewise, when calling `get<your_type>()` or `get_to(your_type&)`, the `from_json` method will be called.
-
-Some important things:
-
-* Those methods **MUST** be in your type's namespace (which can be the global namespace), or the library will not be able to locate them (in this example, they are in namespace `ns`, where `person` is defined).
-* Those methods **MUST** be available (e.g., proper headers must be included) everywhere you use these conversions. Look at [issue 1108](https://github.com/nlohmann/json/issues/1108) for errors that may occur otherwise.
-* When using `get<your_type>()`, `your_type` **MUST** be [DefaultConstructible](https://en.cppreference.com/w/cpp/named_req/DefaultConstructible). (There is a way to bypass this requirement described later.)
-* In function `from_json`, use function [`at()`](https://nlohmann.github.io/json/classnlohmann_1_1basic__json_a93403e803947b86f4da2d1fb3345cf2c.html#a93403e803947b86f4da2d1fb3345cf2c) to access the object values rather than `operator[]`. In case a key does not exist, `at` throws an exception that you can handle, whereas `operator[]` exhibits undefined behavior.
-* You do not need to add serializers or deserializers for STL types like `std::vector`: the library already implements these.
-
-
-## Simplify your life with macros
-
-If you just want to serialize/deserialize some structs, the `to_json`/`from_json` functions can be a lot of boilerplate.
-
-There are two macros to make your life easier as long as you (1) want to use a JSON object as serialization and (2) want to use the member variable names as object keys in that object:
-
-- `NLOHMANN_DEFINE_TYPE_NON_INTRUSIVE(name, member1, member2, ...)` is to be defined inside the namespace of the class/struct to create code for.
-- `NLOHMANN_DEFINE_TYPE_INTRUSIVE(name, member1, member2, ...)` is to be defined inside the class/struct to create code for. This macro can also access private members.
-
-In both macros, the first parameter is the name of the class/struct, and all remaining parameters name the members.
-
-!!! note
-
-    At most 64 member variables can be passed to `NLOHMANN_DEFINE_TYPE_NON_INTRUSIVE` or `NLOHMANN_DEFINE_TYPE_INTRUSIVE`.
-
-??? example
-
-    The `to_json`/`from_json` functions for the `person` struct above can be created with:
-    
-    ```cpp
-    namespace ns {
-        NLOHMANN_DEFINE_TYPE_NON_INTRUSIVE(person, name, address, age)
-    }
-    ```
-    
-    Here is an example with private members, where `NLOHMANN_DEFINE_TYPE_INTRUSIVE` is needed:
-    
-    ```cpp
-    namespace ns {
-        class address {
-          private:
-            std::string street;
-            int housenumber;
-            int postcode;
-            
-          public:
-            NLOHMANN_DEFINE_TYPE_INTRUSIVE(address, street, housenumber, postcode)
-        };
-    }
-    ```
-
-## How do I convert third-party types?
-
-This requires a bit more advanced technique. But first, let's see how this conversion mechanism works:
-
-The library uses **JSON Serializers** to convert types to json.
-The default serializer for `nlohmann::json` is `nlohmann::adl_serializer` (ADL means [Argument-Dependent Lookup](https://en.cppreference.com/w/cpp/language/adl)).
-
-It is implemented like this (simplified):
-
-```cpp
-template <typename T>
-struct adl_serializer {
-    static void to_json(json& j, const T& value) {
-        // calls the "to_json" method in T's namespace
-    }
-
-    static void from_json(const json& j, T& value) {
-        // same thing, but with the "from_json" method
-    }
-};
-```
-
-This serializer works fine when you have control over the type's namespace. However, what about `boost::optional` or `std::filesystem::path` (C++17)? Hijacking the `boost` namespace is pretty bad, and it's illegal to add something other than template specializations to `std`...
-
-To solve this, you need to add a specialization of `adl_serializer` to the `nlohmann` namespace, here's an example:
-
-```cpp
-// partial specialization (full specialization works too)

-## How can I use `get()` for non-default constructible/non-copyable types?
-
-There is a way, if your type is [MoveConstructible](https://en.cppreference.com/w/cpp/named_req/MoveConstructible). You will need to specialize the `adl_serializer` as well, but with a special `from_json` overload:
-
-```cpp
-struct move_only_type {
-    move_only_type() = delete;
-    move_only_type(int ii): i(ii) {}
-    move_only_type(const move_only_type&) = delete;
-    move_only_type(move_only_type&&) = default;
-
-    int i;
-};
-
-namespace nlohmann {
-    template <>
-    struct adl_serializer<move_only_type> {
-        // note: the return type is no longer 'void', and the method only takes
-        // one argument
-        static move_only_type from_json(const json& j) {
-            return {j.get<int>()};
-        }
-
-        // Here's the catch! You must provide a to_json method! Otherwise, you
-        // will not be able to convert move_only_type to json, since you fully
-        // specialized adl_serializer on that type
-        static void to_json(json& j, move_only_type t) {
-            j = t.i;
-        }
-    };
-}
-```
-
-## Can I write my own serializer? (Advanced use)
-
-Yes. You might want to take a look at [`unit-udt.cpp`](https://github.com/nlohmann/json/blob/develop/test/src/unit-udt.cpp) in the test suite, to see a few examples.
-
-If you write your own serializer, you'll need to do a few things:
-
-- use a different `basic_json` alias than `nlohmann::json` (the last template parameter of `basic_json` is the `JSONSerializer`)
-- use your `basic_json` alias (or a template parameter) in all your `to_json`/`from_json` methods
-- use `nlohmann::to_json` and `nlohmann::from_json` when you need ADL
-
-Here is an example, without simplifications, that only accepts types with a size <= 32, and uses ADL.
-
-```cpp
-// You should use void as a second template argument
-// if you don't need compile-time checks on T
-template<typename T, typename SFINAE = typename std::enable_if<sizeof(T) <= 32>::type>
-struct less_than_32_serializer {
-    template <typename BasicJsonType>
-    static void to_json(BasicJsonType& j, T value) {
-        // we want to use ADL, and call the correct to_json overload
-        using nlohmann::to_json; // this method is called by adl_serializer,
-                                 // this is where the magic happens
-        to_json(j, value);
-    }
-
-    template <typename BasicJsonType>
-    static void from_json(const BasicJsonType& j, T& value) {
-        // same thing here
-        using nlohmann::from_json;
-        from_json(j, value);
-    }
-};
-```
-
-Be **very** careful when reimplementing your serializer, you can stack overflow if you don't pay attention:
-
-```cpp
-template <typename T, void>
-struct bad_serializer
-{
-    template <typename BasicJsonType>
-    static void to_json(BasicJsonType& j, const T& value) {
-      // this calls BasicJsonType::json_serializer<T>::to_json(j, value);
-      // if BasicJsonType::json_serializer == bad_serializer ... oops!
-      j = value;
-    }
-
-    template <typename BasicJsonType>
-    static void to_json(const BasicJsonType& j, T& value) {
-      // this calls BasicJsonType::json_serializer<T>::from_json(j, value);
-      // if BasicJsonType::json_serializer == bad_serializer ... oops!
-      value = j.template get<T>(); // oops!
-    }
-};
-```

-# BSON
-
-BSON, short for Binary JSON, is a binary-encoded serialization of JSON-like documents. Like JSON, BSON supports the
-embedding of documents and arrays within other documents and arrays. BSON also contains extensions that allow
-representation of data types that are not part of the JSON spec. For example, BSON has a Date type and a BinData type.

-## Serialization

-The library uses the following mapping from JSON values types to BSON types:

-!!! warning "Incomplete mapping"
-
-    The mapping is **incomplete**, since only JSON-objects (and things
-    contained therein) can be serialized to BSON.
-    Also, integers larger than 9223372036854775807 cannot be serialized to BSON,
-    and the keys may not contain U+0000, since they are serialized a
-    zero-terminated c-strings.

-Binary values with subtype are mapped to tagged values (0xD8..0xDB) depending on the subtype, followed by a byte string,
-see "binary" cells in the table above.

-
-	The mapping is **complete** in the sense that any JSON value type can be converted to a CBOR value.
-
-!!! info "NaN/infinity handling"
-
-	If NaN or Infinity are stored inside a JSON number, they are serialized properly. This behavior differs from the normal JSON serialization which serializes NaN or Infinity to `null`.

-!!! warning "Incomplete mapping"
-
-	The mapping is **incomplete** in the sense that not all CBOR types can be converted to a JSON value. The following CBOR types are not supported and will yield parse errors:
-
-     - date/time (0xC0..0xC1)
-     - bignum (0xC2..0xC3)
-     - decimal fraction (0xC4)
-     - bigfloat (0xC5)
-     - expected conversions (0xD5..0xD7)
-     - simple values (0xE0..0xF3, 0xF8)
-     - undefined (0xF7)
-
-!!! warning "Object keys"
-
-	CBOR allows map keys of any type, whereas JSON only allows strings as keys in object values. Therefore, CBOR maps with keys other than UTF-8 strings are rejected.
-
-!!! warning "Tagged items"
-
-    Tagged items will throw a parse error by default. They can be ignored by passing `cbor_tag_handler_t::ignore` to function `from_cbor`. They can be stored by passing `cbor_tag_handler_t::store` to function `from_cbor`.

-# MessagePack
-
-MessagePack is an efficient binary serialization format. It lets you exchange data among multiple languages like JSON. But it's faster and smaller. Small integers are encoded into a single byte, and typical short strings require only one extra byte in addition to the strings themselves.

-# UBJSON
-
-Universal Binary JSON (UBJSON) is a binary form directly imitating JSON, but requiring fewer bytes of data. It aims to achieve the generality of JSON, combined with being much easier to process than JSON.
-
-!!! abstract "References"
-
-	- [UBJSON Website](http://ubjson.org)
-
-## Serialization
-
-The library uses the following mapping from JSON values types to UBJSON types according to the UBJSON specification:
-
-| JSON value type | value/range                       | UBJSON type    | marker |
-|-----------------|-----------------------------------|----------------|--------|
-| null            | `null`                            | null           | `Z`    |
-| boolean         | `true`                            | true           | `T`    |
-| boolean         | `false`                           | false          | `F`    |
-| number_integer  | -9223372036854775808..-2147483649 | int64          | `L`    |
-| number_integer  | -2147483648..-32769               | int32          | `l`    |
-| number_integer  | -32768..-129                      | int16          | `I`    |
-| number_integer  | -128..127                         | int8           | `i`    |
-| number_integer  | 128..255                          | uint8          | `U`    |
-| number_integer  | 256..32767                        | int16          | `I`    |

-| number_unsigned | 256..32767                        | int16          | `I`    |
-| number_unsigned | 32768..2147483647                 | int32          | `l`    |
-| number_unsigned | 2147483648..9223372036854775807   | int64          | `L`    |
-| number_unsigned | 2147483649..18446744073709551615  | high-precision | `H`    |
-| number_float    | *any value*                       | float64        | `D`    |
-| string          | *with shortest length indicator*  | string         | `S`    |
-| array           | *see notes on optimized format*   | array          | `[`    |
-| object          | *see notes on optimized format*   | map            | `{`    |
-
-!!! success "Complete mapping"
-
-	The mapping is **complete** in the sense that any JSON value type can be converted to a UBJSON value.
-
-	Any UBJSON output created by `to_ubjson` can be successfully parsed by `from_ubjson`.
-
-!!! warning "Size constraints"
-
-	The following values can **not** be converted to a UBJSON value:
-
-      - strings with more than 9223372036854775807 bytes (theoretical)
-
-!!! info "Unused UBJSON markers"
-
-	The following markers are not used in the conversion:
-    
-    - `Z`: no-op values are not created.
-    - `C`: single-byte strings are serialized with `S` markers.
-
-!!! info "NaN/infinity handling"
-
-	If NaN or Infinity are stored inside a JSON number, they are
-    serialized properly. This behavior differs from the `dump()`
-    function which serializes NaN or Infinity to `null`.
-
-!!! info "Optimized formats"
-
-	The optimized formats for containers are supported: Parameter
-    `use_size` adds size information to the beginning of a container and
-    removes the closing marker. Parameter `use_type` further checks
-    whether all elements of a container have the same type and adds the
-    type marker to the beginning of the container. The `use_type`
-    parameter must only be used together with `use_size = true`.
-
-    Note that `use_size = true` alone may result in larger representations -
-    the benefit of this parameter is that the receiving side is
-    immediately informed on the number of elements of the container.
-
-!!! info "Binary values"
-
-	If the JSON data contains the binary type, the value stored is a list
-    of integers, as suggested by the UBJSON documentation.  In particular,
-    this means that serialization and the deserialization of a JSON
-    containing binary values into UBJSON and back will result in a
-    different JSON object.
-
-
-??? example
-
-    ```cpp
-    --8<-- "examples/to_ubjson.cpp"
-    ```
-
-    Output:
-
-    ```c
-    --8<-- "examples/to_ubjson.output"
-    ```
-
-## Deserialization
-
-The library maps UBJSON types to JSON value types as follows:
-
-| UBJSON type | JSON value type                         | marker |
-|-------------|-----------------------------------------|--------|
-| no-op       | *no value, next value is read*          | `N`    |
-| null        | `null`                                  | `Z`    |
-| false       | `false`                                 | `F`    |
-| true        | `true`                                  | `T`    |
-| float32     | number_float                            | `d`    |
-| float64     | number_float                            | `D`    |
-| uint8       | number_unsigned                         | `U`    |
-| int8        | number_integer                          | `i`    |
-| int16       | number_integer                          | `I`    |
-| int32       | number_integer                          | `l`    |
-| int64       | number_integer                          | `L`    |
-| string      | string                                  | `S`    |
-| char        | string                                  | `C`    |
-| array       | array (optimized values are supported)  | `[`    |
-| object      | object (optimized values are supported) | `{`    |

-# Binary Values
-
-The library implements several [binary formats](binary_formats/index.md) that encode JSON in an efficient way. Most of these formats support binary values; that is, values that have semantics define outside the library and only define a sequence of bytes to be stored.
-
-JSON itself does not have a binary value. As such, binary values are an extension that this library implements to store values received by a binary format. Binary values are never created by the JSON parser, and are only part of a serialized JSON text if they have been created manually or via a binary format.
-
-## API for binary values
-
-```plantuml
-class json::binary_t {
-    -- setters --
-    +void set_subtype(std::uint64_t subtype)
-    +void clear_subtype()
-    -- getters --
-    +std::uint64_t subtype() const
-    +bool has_subtype() const
-}
-
-"std::vector<uint8_t>" <|-- json::binary_t
-```
-
-By default, binary values are stored as `std::vector<std::uint8_t>`. This type can be changed by providing a template parameter to the `basic_json` type. To store binary subtypes, the storage type is extended and exposed as `json::binary_t`:
-
-```cpp
-auto binary = json::binary_t({0xCA, 0xFE, 0xBA, 0xBE});
-auto binary_with_subtype = json::binary_t({0xCA, 0xFE, 0xBA, 0xBE}, 42);
-```
-
-There are several convenience functions to check and set the subtype:
-
-```cpp
-binary.has_subtype();                   // returns false
-binary_with_subtype.has_subtype();      // returns true
-
-binary_with_subtype.clear_subtype();
-binary_with_subtype.has_subtype();      // returns true
-
-binary_with_subtype.set_subtype(42);
-binary.set_subtype(23);
-
-binary.subtype();                       // returns 23
-```
-
-As `json::binary_t` is subclassing `std::vector<std::uint8_t>`, all member functions are available:
-
-```cpp
-binary.size();  // returns 4
-binary[1];      // returns 0xFE
-```
-
-JSON values can be constructed from `json::binary_t`:
-
-```cpp
-json j = binary;
-```
-
-Binary values are primitive values just like numbers or strings:
-
-```cpp
-j.is_binary();    // returns true
-j.is_primitive(); // returns true
-```
-
-Given a binary JSON value, the `binary_t` can be accessed by reference as via `get_binary()`:
-
-```cpp
-j.get_binary().has_subtype();  // returns true
-j.get_binary().size();         // returns 4
-```
-
-For convenience, binary JSON values can be constructed via `json::binary`:
-
-```cpp
-auto j2 = json::binary({0xCA, 0xFE, 0xBA, 0xBE}, 23);
-auto j3 = json::binary({0xCA, 0xFE, 0xBA, 0xBE});
-
-j2 == j;                        // returns true
-j3.get_binary().has_subtype();  // returns false
-j3.get_binary().subtype();      // returns std::uint64_t(-1) as j3 has no subtype
-```
-
-
-
-## Serialization
-
-Binary values are serialized differently according to the formats.
-
-### JSON
-
-JSON does not have a binary type, and this library does not introduce a new type as this would break conformance. Instead, binary values are serialized as an object with two keys: `bytes` holds an array of integers, and `subtype` is an integer or `null`.
-
-??? example
-
-    Code:
-
-    ```cpp
-    // create a binary value of subtype 42
-    json j;
-    j["binary"] = json::binary({0xCA, 0xFE, 0xBA, 0xBE}, 42);
-    
-    // serialize to standard output
-    std::cout << j.dump(2) << std::endl;
-    ```
-    
-    Output:
-    
-    ```json
-    {
-      "binary": {
-        "bytes": [202, 254, 186, 190],
-        "subtype": 42
-      }
-    }
-    ```
-
-!!! warning "No roundtrip for binary values"
-
-    The JSON parser will not parse the objects generated by binary values back to binary values. This is by design to remain standards compliant. Serializing binary values to JSON is only implemented for debugging purposes.
-
-### BSON
-
-[BSON](binary_formats/bson.md) supports binary values and subtypes. If a subtype is given, it is used and added as unsigned 8-bit integer. If no subtype is given, the generic binary subtype 0x00 is used.
-
-??? example
-
-    Code:
-    
-    ```cpp
-    // create a binary value of subtype 42
-    json j;
-    j["binary"] = json::binary({0xCA, 0xFE, 0xBA, 0xBE}, 42);
-
-    // convert to BSON
-    auto v = json::to_bson(j);      
-    ```
-            
-    `v` is a `std::vector<std::uint8t>` with the following 22 elements:
-    
-    ```c
-    0x16 0x00 0x00 0x00                         // number of bytes in the document
-        0x05                                    // binary value
-            0x62 0x69 0x6E 0x61 0x72 0x79 0x00  // key "binary" + null byte
-            0x04 0x00 0x00 0x00                 // number of bytes
-            0x2a                                // subtype
-            0xCA 0xFE 0xBA 0xBE                 // content
-    0x00                                        // end of the document
-    ```
-
-    Note that the serialization preserves the subtype, and deserializing `v` would yield the following value:
-
-    ```json
-    {
-      "binary": {
-        "bytes": [202, 254, 186, 190],
-        "subtype": 42
-      }
-    }
-    ```
-
-### CBOR
-
-[CBOR](binary_formats/cbor.md) supports binary values, but no subtypes. Subtypes will be serialized as tags. Any binary value will be serialized as byte strings. The library will choose the smallest representation using the length of the byte array.
-
-??? example
-
-    Code:
-    
-    ```cpp
-    // create a binary value of subtype 42
-    json j;
-    j["binary"] = json::binary({0xCA, 0xFE, 0xBA, 0xBE}, 42);
-
-    // convert to CBOR
-    auto v = json::to_cbor(j);      
-    ```
-            
-    `v` is a `std::vector<std::uint8t>` with the following 15 elements:
-    
-    ```c
-    0xA1                                   // map(1)
-        0x66                               // text(6)
-            0x62 0x69 0x6E 0x61 0x72 0x79  // "binary"
-        0xD8 0x2A                          // tag(42)
-        0x44                               // bytes(4)
-            0xCA 0xFE 0xBA 0xBE            // content
-    ```
-
-    Note that the subtype is serialized as tag. However, parsing tagged values yield a parse error unless `json::cbor_tag_handler_t::ignore` or `json::cbor_tag_handler_t::store` is passed to `json::from_cbor`.
-
-    ```json
-    {
-      "binary": {
-        "bytes": [202, 254, 186, 190],
-        "subtype": null
-      }
-    }
-    ```
-
-### MessagePack
-
-[MessagePack](binary_formats/messagepack.md) supports binary values and subtypes. If a subtype is given, the ext family is used. The library will choose the smallest representation among fixext1, fixext2, fixext4, fixext8, ext8, ext16, and ext32. The subtype is then added as signed 8-bit integer.
-
-If no subtype is given, the bin family (bin8, bin16, bin32) is used.
-
-??? example
-
-    Code:
-    
-    ```cpp
-    // create a binary value of subtype 42
-    json j;
-    j["binary"] = json::binary({0xCA, 0xFE, 0xBA, 0xBE}, 42);
-
-    // convert to MessagePack
-    auto v = json::to_msgpack(j);      
-    ```
-            
-    `v` is a `std::vector<std::uint8t>` with the following 14 elements:
-    
-    ```c
-    0x81                                   // fixmap1
-        0xA6                               // fixstr6
-            0x62 0x69 0x6E 0x61 0x72 0x79  // "binary"
-        0xD6                               // fixext4
-            0x2A                           // subtype
-            0xCA 0xFE 0xBA 0xBE            // content
-    ```
-
-    Note that the serialization preserves the subtype, and deserializing `v` would yield the following value:
-
-    ```json
-    {
-      "binary": {
-        "bytes": [202, 254, 186, 190],
-        "subtype": 42
-      }
-    }
-    ```
-
-### UBJSON
-
-[UBJSON](binary_formats/ubjson.md) neither supports binary values nor subtypes, and proposes to serialize binary values as array of uint8 values. This translation is implemented by the library.
-
-??? example
-
-    Code:
-    
-    ```cpp
-    // create a binary value of subtype 42 (will be ignored in UBJSON)
-    json j;
-    j["binary"] = json::binary({0xCA, 0xFE, 0xBA, 0xBE}, 42);
-
-    // convert to UBJSON
-    auto v = json::to_msgpack(j);      
-    ```
-            
-    `v` is a `std::vector<std::uint8t>` with the following 20 elements:
-    
-    ```c
-    0x7B                                             // '{'
-        0x69 0x06                                    // i 6 (length of the key)
-        0x62 0x69 0x6E 0x61 0x72 0x79                // "binary"
-        0x5B                                         // '['
-            0x55 0xCA 0x55 0xFE 0x55 0xBA 0x55 0xBE  // content (each byte prefixed with 'U')
-        0x5D                                         // ']'
-    0x7D                                             // '}'
-    ```
-
-    The following code uses the type and size optimization for UBJSON:
-
-    ```cpp
-    // convert to UBJSON using the size and type optimization
-    auto v = json::to_ubjson(j, true, true);
-    ```
-
-    The resulting vector has 23 elements; the optimization is not effective for examples with few values:
-
-    ```c
-    0x7B                                // '{'
-        0x24                            // '$' type of the object elements
-        0x5B                            // '[' array
-        0x23 0x69 0x01                  // '#' i 1 number of object elements
-        0x69 0x06                       // i 6 (length of the key)
-        0x62 0x69 0x6E 0x61 0x72 0x79   // "binary"
-            0x24 0x55                   // '$' 'U' type of the array elements: unsigned integers
-            0x23 0x69 0x04              // '#' i 4 number of array elements
-            0xCA 0xFE 0xBA 0xBE         // content
-    ```
-
-    Note that subtype (42) is **not** serialized and that UBJSON has **no binary type**, and deserializing `v` would yield the following value:
-
-    ```json
-    {
-      "binary": [202, 254, 186, 190]
-    }
-    ```

-# Comments
-
-This library does not support comments *by default*. It does so for three reasons:
-
-1. Comments are not part of the [JSON specification](https://tools.ietf.org/html/rfc8259). You may argue that `//` or `/* */` are allowed in JavaScript, but JSON is not JavaScript.
-2. This was not an oversight: Douglas Crockford [wrote on this](https://plus.google.com/118095276221607585885/posts/RK8qyGVaGSr) in May 2012:
-
-	> 	I removed comments from JSON because I saw people were using them to hold parsing directives, a practice which would have destroyed interoperability.  I know that the lack of comments makes some people sad, but it shouldn't. 
-
-	> 	Suppose you are using JSON to keep configuration files, which you would like to annotate. Go ahead and insert all the comments you like. Then pipe it through JSMin before handing it to your JSON parser.
-
-3. It is dangerous for interoperability if some libraries would add comment support while others don't. Please check [The Harmful Consequences of the Robustness Principle](https://tools.ietf.org/html/draft-iab-protocol-maintenance-01) on this.
-
-However, you can pass set parameter `ignore_comments` to `#!c true` in the parse function to ignore `//` or `/* */` comments. Comments will then be treated as whitespace.
-
-!!! example
-
-    Consider the following JSON with comments.
-
-    ```json
-    {
-        // update in 2006: removed Pluto
-        "planets": ["Mercury", "Venus", "Earth", "Mars",
-                    "Jupiter", "Uranus", "Neptune" /*, "Pluto" */]
-    }
-    ```
-    
-    When calling `parse` without additional argument, a parse error exception is thrown. If `ignore_comments` is set to `#! true`, the comments are ignored during parsing:
-
-    ```cpp
-    #include <iostream>
-    #include "json.hpp"
-    
-    using json = nlohmann::json;
-    
-    int main()
-    {
-        std::string s = R"(

-                        "Jupiter", "Uranus", "Neptune" /*, "Pluto" */]
-        }
-        )";
-        
-        try
-        {
-            json j = json::parse(s);
-        }
-        catch (json::exception &e)
-        {
-            std::cout << e.what() << std::endl;
-        }
-

-                             /* ignore_comments */ true);
-        std::cout << j.dump(2) << '\n';
-    }

-# Checked access: at
-
-## Overview
-
-The `#!cpp at()` member function performs checked access; that is, it returns a reference to the desired value if it exists and throws a [`basic_json::out_of_range` exception](../../home/exceptions.md#out-of-range) otherwise.
-
-??? example
-
-    Consider the following JSON value:
-    
-    ```json
-    {
-        "name": "Mary Smith",
-        "age": 42,
-        "hobbies": ["hiking", "reading"]
-    }
-    ```
-    
-    Assume the value is parsed to a `json` variable `j`.
-
-    | expression | value |
-    | ---------- | ----- |
-    | `#!cpp j`  | `#!json {"name": "Mary Smith", "age": 42, "hobbies": ["hiking", "reading"]}` |
-    | `#!cpp j.at("name")`  | `#!json "Mary Smith"` |
-    | `#!cpp j.at("age")`  | `#!json 42` |
-    | `#!cpp j.at("hobbies")`  | `#!json ["hiking", "reading"]` |
-    | `#!cpp j.at("hobbies").at(0)`  | `#!json "hiking"` |
-    | `#!cpp j.at("hobbies").at(1)`  | `#!json "reading"` |
-
-The return value is a reference, so it can be modified by the original value.
-
-??? example
-
-    ```cpp
-    j.at("name") = "John Smith";
-    ```
-    
-    This code produces the following JSON value:
-    
-    ```json
-    {
-        "name": "John Smith",
-        "age": 42,
-        "hobbies": ["hiking", "reading"]
-    }
-    ```
-
-When accessing an invalid index (i.e., an index greater than or equal to the array size) or the passed object key is non-existing, an exception is thrown.
-
-??? example
-
-    ```cpp
-    j.at("hobbies").at(3) = "cooking";
-    ```
-    
-    This code produces the following exception:
-    
-    ```
-    [json.exception.out_of_range.401] array index 3 is out of range
-    ```
-
-## Notes
-
-
-!!! failure "Exceptions"
-
-    - `at` can only be used with objects (with a string argument) or with arrays (with a numeric argument). For other types, a [`basic_json::type_error`](../../home/exceptions.md#jsonexceptiontype_error304) is thrown.
-    - [`basic_json::out_of_range` exception](../../home/exceptions.md#out-of-range) exceptions are thrown if the provided key is not found in an object or the provided index is invalid.

-# Unchecked access: operator[]
-
-## Overview
-
-Elements in a JSON object and a JSON array can be accessed via `#!cpp operator[]` similar to a `#!cpp std::map` and a `#!cpp std::vector`, respectively.
-
-??? example
-
-    Consider the following JSON value:
-    
-    ```json
-    {
-        "name": "Mary Smith",
-        "age": 42,
-        "hobbies": ["hiking", "reading"]
-    }
-    ```
-    
-    Assume the value is parsed to a `json` variable `j`.
-
-    | expression | value |
-    | ---------- | ----- |
-    | `#!cpp j`  | `#!json {"name": "Mary Smith", "age": 42, "hobbies": ["hiking", "reading"]}` |
-    | `#!cpp j["name"]`  | `#!json "Mary Smith"` |
-    | `#!cpp j["age"]`  | `#!json 42` |
-    | `#!cpp j["hobbies"]`  | `#!json ["hiking", "reading"]` |
-    | `#!cpp j["hobbies"][0]`  | `#!json "hiking"` |
-    | `#!cpp j["hobbies"][1]`  | `#!json "reading"` |
-
-The return value is a reference, so it can modify the original value. In case the passed object key is non-existing, a `#!json null` value is inserted which can be immediately be overwritten.
-
-??? example
-
-    ```cpp
-    j["name"] = "John Smith";
-    j["maidenName"] = "Jones";
-    ```
-    
-    This code produces the following JSON value:
-    
-    ```json
-    {
-        "name": "John Smith",
-        "maidenName": "Jones",
-        "age": 42,
-        "hobbies": ["hiking", "reading"]
-    }
-    ```
-
-When accessing an invalid index (i.e., an index greater than or equal to the array size), the JSON array is resized such that the passed index is the new maximal index. Intermediate values are filled with `#!json null`.
-
-??? example
-
-    ```cpp
-    j["hobbies"][0] = "running";
-    j["hobbies"][3] = "cooking";
-    ```
-    
-    This code produces the following JSON value:
-    
-    ```json
-    {
-        "name": "John Smith",
-        "maidenName": "Jones",
-        "age": 42,
-        "hobbies": ["running", "reading", null, "cooking"]
-    }
-    ```
-
-## Notes
-
-!!! info "Design rationale"
-
-    The library behaves differently to `#!cpp std::vector` and `#!cpp std::map`:
-    
-    - `#!cpp std::vector::operator[]` never inserts a new element.
-    - `#!cpp std::map::operator[]` is not available for const values.
-    
-    The type `#!cpp json` wraps all JSON value types. It would be impossible to remove `operator[]` for const objects. At the same time, inserting elements for non-const objects is really convenient as it avoids awkward `insert` calls. To this end, we decided to have an inserting non-const behavior for both arrays and objects.
-
-!!! info
-
-    The access is unchecked. In case the passed object key does not exist or the passed array index is invalid, no exception is thrown.
-
-!!! danger
-
-    - It is **undefined behavior** to access a const object with a non-existing key.
-    - It is **undefined behavior** to access a const array with an invalid index.
-    - In debug mode, an **assertion** will fire in both cases. You can disable assertions by defining the preprocessor symbol `#!cpp NDEBUG` or redefine the macro [`JSON_ASSERT(x)`](../macros.md#json_assertx).
-
-!!! failure "Exceptions"
-
-    `operator[]` can only be used with objects (with a string argument) or with arrays (with a numeric argument). For other types, a [`basic_json::type_error`](../../home/exceptions.md#jsonexceptiontype_error305) is thrown.

-# Specializing enum conversion
-
-By default, enum values are serialized to JSON as integers. In some cases this could result in undesired behavior. If an
-enum is modified or re-ordered after data has been serialized to JSON, the later de-serialized JSON data may be
-undefined or a different enum value than was originally intended.
-
-It is possible to more precisely specify how a given enum is mapped to and from JSON as shown below:
-
-```cpp
-// example enum type declaration
-enum TaskState {
-    TS_STOPPED,
-    TS_RUNNING,
-    TS_COMPLETED,
-    TS_INVALID=-1,
-};
-
-// map TaskState values to JSON as strings
-NLOHMANN_JSON_SERIALIZE_ENUM( TaskState, {
-    {TS_INVALID, nullptr},
-    {TS_STOPPED, "stopped"},
-    {TS_RUNNING, "running"},
-    {TS_COMPLETED, "completed"},
-})
-```
-
-The `NLOHMANN_JSON_SERIALIZE_ENUM()` macro declares a set of `to_json()` / `from_json()` functions for type `TaskState`
-while avoiding repetition and boilerplate serialization code.
-
-## Usage
-
-```cpp
-// enum to JSON as string
-json j = TS_STOPPED;
-assert(j == "stopped");
-
-// json string to enum
-json j3 = "running";
-assert(j3.get<TaskState>() == TS_RUNNING);
-
-// undefined json value to enum (where the first map entry above is the default)
-json jPi = 3.14;
-assert(jPi.get<TaskState>() == TS_INVALID );
-```
-
-## Notes
-
-Just as in [Arbitrary Type Conversions](#arbitrary-types-conversions) above,
-
-- `NLOHMANN_JSON_SERIALIZE_ENUM()` MUST be declared in your enum type's namespace (which can be the global namespace),
-  or the library will not be able to locate it, and it will default to integer serialization.
-- It MUST be available (e.g., proper headers must be included) everywhere you use the conversions.
-
-Other Important points:
-
-- When using `get<ENUM_TYPE>()`, undefined JSON values will default to the first pair specified in your map. Select this
-  default pair carefully.
-- If an enum or JSON value is specified more than once in your map, the first matching occurrence from the top of the
-  map will be returned when converting to or from JSON.

-# Iterators
-
-## Overview
-
-A `basic_json` value is a container and allows access via iterators. Depending on the value type, `basic_json` stores zero or more values.
-
-As for other containers, `begin()` returns an iterator to the first value and `end()` returns an iterator to the value following the last value. The latter iterator is a placeholder and cannot be dereferenced. In case of null values, empty arrays, or empty objects, `begin()` will return `end()`.
-
-![Illustration from cppreference.com](../images/range-begin-end.svg)
-
-### Iteration order for objects
-
-When iterating over objects, values are ordered with respect to the `object_comparator_t` type which defaults to `std::less`. See the [types documentation](types/index.md#key-order) for more information.
-
-??? example
-
-    ```cpp
-    // create JSON object {"one": 1, "two": 2, "three": 3}
-    json j;
-    j["one"] = 1;
-    j["two"] = 2;
-    j["three"] = 3;
-    
-    for (auto it = j.begin(); it != j.end(); ++it)
-    {
-        std::cout << *it << std::endl;
-    }
-    ```
-    
-    Output:
-    
-    ```json
-    1
-    3
-    2
-    ```
-    
-    The reason for the order is the lexicographic ordering of the object keys "one", "three", "two".
-
-### Access object key during iteration
-
-The JSON iterators have two member functions, `key()` and `value()` to access the object key and stored value, respectively. When calling `key()` on a non-object iterator, an [invalid_iterator.207](../home/exceptions.md#jsonexceptioninvalid_iterator207) exception is thrown.
-
-??? example
-
-    ```cpp
-    // create JSON object {"one": 1, "two": 2, "three": 3}
-    json j;
-    j["one"] = 1;
-    j["two"] = 2;
-    j["three"] = 3;
-    
-    for (auto it = j.begin(); it != j.end(); ++it)
-    {
-        std::cout << it.key() << " : " << it.value() << std::endl;
-    }
-    ```
-    
-    Output:
-    
-    ```json
-    one : 1
-    three : 3
-    two : 2
-    ```
-
-### Range-based for loops
-
-C++11 allows using range-based for loops to iterate over a container.
-
-```cpp
-for (auto it : j_object)
-{
-    // "it" is of type json::reference and has no key() member
-    std::cout << "value: " << it << '\n';
-}
-```
-
-For this reason, the `items()` function allows accessing `iterator::key()` and `iterator::value()` during range-based for loops. In these loops, a reference to the JSON values is returned, so there is no access to the underlying iterator.
-
-```cpp
-for (auto& el : j_object.items())
-{
-    std::cout << "key: " << el.key() << ", value:" << el.value() << '\n';
-}
-```
-
-The items() function also allows using structured bindings (C++17):
-
-```cpp
-for (auto& [key, val] : j_object.items())
-{
-    std::cout << "key: " << key << ", value:" << val << '\n';
-}
-```
-
-!!! note
-
-    When iterating over an array, `key()` will return the index of the element as string. For primitive types (e.g., numbers), `key()` returns an empty string.
-    
-!!! warning
-
-    Using `items()` on temporary objects is dangerous. Make sure the object's lifetime exceeds the iteration. See <https://github.com/nlohmann/json/issues/2040> for more information.
-
-### Reverse iteration order
-
-`rbegin()` and `rend()` return iterators in the reverse sequence.
-    
-![Illustration from cppreference.com](../images/range-rbegin-rend.svg)
-
-??? example
-
-    ```cpp
-    json j = {1, 2, 3, 4};
-
-    for (auto it = j.begin(); it != j.end(); ++it)
-    {
-        std::cout << *it << std::endl;
-    }
-    ```
-    
-    Output:
-    
-    ```json
-    4
-    3
-    2
-    1
-    ```
-
-### Iterating strings and binary values
-
-Note that "value" means a JSON value in this setting, not values stored in the underlying containers. That is, `*begin()` returns the complete string or binary array and is also safe the underlying string or binary array is empty.
-
-??? example
-
-    ```cpp
-    json j = "Hello, world";
-    for (auto it = j.begin(); it != j.end(); ++it)
-    {
-        std::cout << *it << std::endl;
-    }
-    ```
-    
-    Output:
-    
-    ```json
-    "Hello, world"
-    ```

-# JSON Patch and Diff
-
-## Patches
-
-JSON Patch ([RFC 6902](https://tools.ietf.org/html/rfc6902)) defines a JSON document structure for expressing a sequence
-of operations to apply to a JSON document. With the `patch` function, a JSON Patch is applied to the current JSON value
-by executing all operations from the patch.
-
-??? example
-
-    The following code shows how a JSON patch is applied to a value.
-
-    ```cpp
-    --8<-- "examples/patch.cpp"
-    ```
-    
-    Output:
-
-    ```json
-    --8<-- "examples/patch.output"
-    ```
-
-## Diff
-
-The library can also calculate a JSON patch (i.e., a **diff**) given two JSON values.
-
-!!! success "Invariant"
-
-    For two JSON values *source* and *target*, the following code yields always true:
-
-    ```cüü
-    source.patch(diff(source, target)) == target;
-    ```
-
-??? example
-
-    The following code shows how a JSON patch is created as a diff for two JSON values.
-
-    ```cpp
-    --8<-- "examples/diff.cpp"
-    ```
-    
-    Output:
-
-    ```json
-    --8<-- "examples/diff.output"

-# Supported Macros
-
-Some aspects of the library can be configured by defining preprocessor macros before including the `json.hpp` header.
-
-## `JSON_ASSERT(x)`
-
-The default value is `#!cpp assert(x)`.
-
-## `JSON_CATCH_USER(exception)`
-
-This macro overrides `#!cpp catch` calls inside the library. The argument is the type of the exception to catch. As of
-version 3.8.0, the library only catches `std::out_of_range` exceptions internally to rethrow them as
-[`json::out_of_range`](../home/exceptions.md#out-of-range) exceptions. The macro is always followed by a scope.
-
-See [Switch off exceptions](../home/exceptions.md#switch-off-exceptions) for an example.
-
-## `JSON_DIAGNOSTICS`
-
-This macro enables extended diagnostics for exception messages. Possible values are `1` to enable or `0` to disable
-(default).
-
-When enabled, exception messages contain a [JSON Pointer](json_pointer.md) to the JSON value that triggered the
-exception, see [Extended diagnostic messages](../home/exceptions.md#extended-diagnostic-messages) for an example. Note
-that enabling this macro increases the size of every JSON value by one pointer and adds some runtime overhead.
-
-The diagnostics messages can also be controlled with the CMake option `JSON_Diagnostics` (`OFF` by default) which sets
-`JSON_DIAGNOSTICS` accordingly.
-
-## `JSON_HAS_CPP_11`, `JSON_HAS_CPP_14`, `JSON_HAS_CPP_17`, `JSON_HAS_CPP_20`
-
-The library targets C++11, but also supports some features introduced in later C++ versions (e.g., `std::string_view`
-support for C++17). For these new features, the library implements some preprocessor checks to determine the C++
-standard. By defining any of these symbols, the internal check is overridden and the provided C++ version is
-unconditionally assumed. This can be helpful for compilers that only implement parts of the standard and would be
-detected incorrectly.
-
-## `JSON_HAS_FILESYSTEM`, `JSON_HAS_EXPERIMENTAL_FILESYSTEM`
-
-When compiling with C++17, the library provides conversions from and to `std::filesystem::path`. As compiler support
-for filesystem is limited, the library tries to detect whether `<filesystem>`/`std::filesystem` (`JSON_HAS_FILESYSTEM`)
-or `<experimental/filesystem>`/`std::experimental::filesystem` (`JSON_HAS_EXPERIMENTAL_FILESYSTEM`) should be used.
-To override the built-in check, define `JSON_HAS_FILESYSTEM` or `JSON_HAS_EXPERIMENTAL_FILESYSTEM` to `1`.
-
-## `JSON_NOEXCEPTION`
-
-Exceptions can be switched off by defining the symbol `JSON_NOEXCEPTION`. When defining `JSON_NOEXCEPTION`, `#!cpp try`
-is replaced by `#!cpp if (true)`, `#!cpp catch` is replaced by `#!cpp if (false)`, and `#!cpp throw` is replaced by
-`#!cpp std::abort()`.
-
-The same effect is achieved by setting the compiler flag `-fno-exceptions`.
-
-Note the explanatory [`what()`](https://en.cppreference.com/w/cpp/error/exception/what) string of exceptions is not
-available for MSVC if exceptions are disabled, see [#2824](https://github.com/nlohmann/json/discussions/2824).
-
-## `JSON_NO_IO`
-
-When defined, headers `<cstdio>`, `<ios>`, `<iosfwd>`, `<istream>`, and `<ostream>` are not included and parse functions
-relying on these headers are excluded. This is relevant for environment where these I/O functions are disallowed for
-security reasons (e.g., Intel Software Guard Extensions (SGX)).
-
-## `JSON_SKIP_UNSUPPORTED_COMPILER_CHECK`
-
-When defined, the library will not create a compile error when a known unsupported compiler is detected. This allows to
-use the library with compilers that do not fully support C++11 and may only work if unsupported features are not used.
-
-## `JSON_THROW_USER(exception)`
-
-This macro overrides `#!cpp throw` calls inside the library. The argument is the exception to be thrown. Note that
-`JSON_THROW_USER` should leave the current scope (e.g., by throwing or aborting), as continuing after it may yield
-undefined behavior.
-
-See [Switch off exceptions](../home/exceptions.md#switch-off-exceptions) for an example.
-
-## `JSON_TRY_USER`
-
-This macro overrides `#!cpp try` calls inside the library. It has no arguments and is always followed by a scope.
-
-See [Switch off exceptions](../home/exceptions.md#switch-off-exceptions) for an example.
-
-## `JSON_USE_IMPLICIT_CONVERSIONS`
-
-When defined to `0`, implicit conversions are switched off. By default, implicit conversions are switched on.
-
-??? example
-
-    This is an example for an implicit conversion:
-    
-    ```cpp
-    json j = "Hello, world!";
-    std::string s = j;
-    ```
-    
-    When `JSON_USE_IMPLICIT_CONVERSIONS` is defined to `0`, the code above does no longer compile. Instead, it must be
-    written like this:
-
-    ```cpp
-    json j = "Hello, world!";
-    auto s = j.get<std::string>();
-    ```
-
-Implicit conversions can also be controlled with the CMake option `JSON_ImplicitConversions` (`ON` by default) which
-sets `JSON_USE_IMPLICIT_CONVERSIONS` accordingly.
-
-## `NLOHMANN_DEFINE_TYPE_INTRUSIVE(type, member...)`
-
-This macro can be used to simplify the serialization/deserialization of types if (1) want to use a JSON object as
-serialization and (2) want to use the member variable names as object keys in that object.
-
-The macro is to be defined inside the class/struct to create code for. Unlike
-[`NLOHMANN_DEFINE_TYPE_NON_INTRUSIVE`](#nlohmann_define_type_non_intrusivetype-member), it can access private members.
-The first parameter is the name of the class/struct, and all remaining parameters name the members.
-
-See [Simplify your life with macros](arbitrary_types.md#simplify-your-life-with-macros) for an example.
-
-## `NLOHMANN_DEFINE_TYPE_NON_INTRUSIVE(type, member...)`
-
-This macro can be used to simplify the serialization/deserialization of types if (1) want to use a JSON object as
-serialization and (2) want to use the member variable names as object keys in that object.
-
-The macro is to be defined inside the namespace of the class/struct to create code for. Private members cannot be
-accessed. Use [`NLOHMANN_DEFINE_TYPE_INTRUSIVE`](#nlohmann_define_type_intrusivetype-member) in these scenarios. The
-first parameter is the name of the class/struct, and all remaining parameters name the members.
-
-See [Simplify your life with macros](arbitrary_types.md#simplify-your-life-with-macros) for an example.
-
-## `NLOHMANN_JSON_SERIALIZE_ENUM(type, ...)`
-
-This macro simplifies the serialization/deserialization of enum types. See
-[Specializing enum conversion](enum_conversion.md) for more information.
-
-## `NLOHMANN_JSON_VERSION_MAJOR`, `NLOHMANN_JSON_VERSION_MINOR`, `NLOHMANN_JSON_VERSION_PATCH`
-
-These macros are defined by the library and contain the version numbers according to
-[Semantic Versioning 2.0.0](https://semver.org).

-# JSON Merge Patch
-
-The library supports JSON Merge Patch ([RFC 7386](https://tools.ietf.org/html/rfc7386)) as a patch format.
-The merge patch format is primarily intended for use with the HTTP PATCH method as a means of describing a set of modifications to a target resource's content. This function applies a merge patch to the current JSON value.
-
-Instead of using [JSON Pointer](json_pointer.md) to specify values to be manipulated, it describes the changes using a syntax that closely mimics the document being modified.
-

-# Object Order
-
-The [JSON standard](https://tools.ietf.org/html/rfc8259.html) defines objects as "an unordered collection of zero or more name/value pairs". As such, an implementation does not need to preserve any specific order of object keys.
-
-The default type `nlohmann::json` uses a `std::map` to store JSON objects, and thus stores object keys **sorted alphabetically**.
-
-??? example
-
-    ```cpp
-    #include <iostream>
-    #include "json.hpp"
-    
-    using json = nlohmann::json;
-    
-    int main()
-    {
-        json j;
-        j["one"] = 1;
-        j["two"] = 2;
-        j["three"] = 3;
-        
-        std::cout << j.dump(2) << '\n';
-    }
-    ```
-    
-    Output:
-
-    ```json
-    {
-      "one": 1,
-      "three": 3,
-      "two": 2
-    }
-    ```
-
-If you do want to preserve the **insertion order**, you can try the type [`nlohmann::ordered_json`](https://github.com/nlohmann/json/issues/2179).
-
-??? example
-
-    ```cpp
-    #include <iostream>
-    #include <nlohmann/json.hpp>
-    
-    using ordered_json = nlohmann::ordered_json;
-    
-    int main()
-    {
-        ordered_json j;
-        j["one"] = 1;
-        j["two"] = 2;
-        j["three"] = 3;
-        
-        std::cout << j.dump(2) << '\n';
-    }
-    ```
-    
-    Output:
-    
-    ```json
-    {
-      "one": 1,
-      "two": 2,
-      "three": 3
-    }
-    ```
-
-Alternatively, you can use a more sophisticated ordered map like [`tsl::ordered_map`](https://github.com/Tessil/ordered-map) ([integration](https://github.com/nlohmann/json/issues/546#issuecomment-304447518)) or [`nlohmann::fifo_map`](https://github.com/nlohmann/fifo_map) ([integration](https://github.com/nlohmann/json/issues/485#issuecomment-333652309)).

-# Parsing and Exceptions
-
-When the input is not valid JSON, an exception of type [`parse_error`](../../home/exceptions.md#parse-errors) is thrown. This exception contains the position in the input where the error occurred, together with a diagnostic message and the last read input token. The exceptions page contains a [list of examples for parse error exceptions](../../home/exceptions.md#parse-errors). In case you process untrusted input, always enclose your code with a `#!cpp try`/`#!cpp catch` block, like
-
-```cpp
-json j;
-try
-{
-    j = json::parse(my_input);
-}
-catch (json::parse_error& ex)
-{
-    std::cerr << "parse error at byte " << ex.byte << std::endl;
-}
-```
-
-In case exceptions are undesired or not supported by the environment, there are different ways to proceed:
-
-
-## Switch off exceptions
-
-The `parse()` function accepts as last parameter a `#!cpp bool` variable `allow_exceptions` which controls whether an exception is thrown when a parse error occurs (`#!cpp true`, default) or whether a discarded value should be returned (`#!cpp false`).
-
-```cpp
-json j = json::parse(my_input, nullptr, false);
-if (j.is_discarded())
-{
-    std::cerr << "parse error" << std::endl;
-}
-```
-
-Note there is no diagnostic information available in this scenario.
-
-## Use accept() function
-
-Alternatively, function `accept()` can be used which does not return a `json` value, but a `#!cpp bool` indicating whether the input is valid JSON.
-
-```cpp
-if (!json::accept(my_input))
-{
-    std::cerr << "parse error" << std::endl;
-}
-```
-
-Again, there is no diagnostic information available.
-
-
-## User-defined SAX interface
-
-Finally, you can implement the [SAX interface](sax_interface.md) and decide what should happen in case of a parse error.
-
-This function has the following interface:
-
-```cpp
-bool parse_error(std::size_t position,
-                 const std::string& last_token,
-                 const json::exception& ex);
-```
-
-The return value indicates whether the parsing should continue, so the function should usually return `#!cpp false`.
-
-??? example
-
-    ```cpp
-    #include <iostream>
-    #include "json.hpp"
-    
-    using json = nlohmann::json;
-    
-    class sax_no_exception : public nlohmann::detail::json_sax_dom_parser<json>
-    {
-      public:
-        sax_no_exception(json& j)
-          : nlohmann::detail::json_sax_dom_parser<json>(j, false)
-        {}
-        
-        bool parse_error(std::size_t position,
-                         const std::string& last_token,
-                         const json::exception& ex)
-        {
-            std::cerr << "parse error at input byte " << position << "\n"
-                      << ex.what() << "\n"
-                      << "last read: \"" << last_token << "\""
-                      << std::endl;
-            return false;
-        }
-    };
-    
-    int main()
-    {
-        std::string myinput = "[1,2,3,]";
-    
-        json result;
-        sax_no_exception sax(result);
-        
-        bool parse_result = json::sax_parse(myinput, &sax);
-        if (!parse_result)
-        {
-            std::cerr << "parsing unsuccessful!" << std::endl;
-        }
-        
-        std::cout << "parsed value: " << result << std::endl;
-    }
-    ```
-
-    Output:
-    
-    ```
-    parse error at input byte 8
-    [json.exception.parse_error.101] parse error at line 1, column 8: syntax error while parsing value - unexpected ']'; expected '[', '{', or a literal
-    last read: "3,]"
-    parsing unsuccessful!

-# Parser Callbacks
-
-## Overview
-
-With a parser callback function, the result of parsing a JSON text can be influenced. When passed to `parse`, it is called on certain events
-(passed as `parse_event_t` via parameter `event`) with a set recursion depth `depth` and context JSON value `parsed`. The return value of the
-callback function is a boolean indicating whether the element that emitted the callback shall be kept or not.
-
-The type of the callback function is:
-
-```cpp
-template<typename BasicJsonType>
-using parser_callback_t =
-    std::function<bool(int depth, parse_event_t event, BasicJsonType& parsed)>;
-```
-
-
-## Callback event types
-
-We distinguish six scenarios (determined by the event type) in which the callback function can be called. The following table describes the values
-of the parameters `depth`, `event`, and `parsed`.
-
-| parameter `event`             | description                                               | parameter `depth`                         | parameter `parsed`               |
-|-------------------------------|-----------------------------------------------------------|-------------------------------------------|----------------------------------|
-| `parse_event_t::object_start` | the parser read `{` and started to process a JSON object  | depth of the parent of the JSON object    | a JSON value with type discarded |
-| `parse_event_t::key`          | the parser read a key of a value in an object             | depth of the currently parsed JSON object | a JSON string containing the key |

-
-??? example
-
-    When parsing the following JSON text,
-    
-    ```json
-    {
-        "name": "Berlin",
-        "location": [
-            52.519444,
-            13.406667
-        ]
-    }
-    ```
-    
-    these calls are made to the callback function:
-    
-    | event          | depth | parsed |
-    | -------------- | ----- | ------ |
-    | `object_start` | 0     | *discarded* |
-    | `key`          | 1     | `#!json "name"` |
-    | `value`        | 1     | `#!json "Berlin"` |
-    | `key`          | 1     | `#!json "location"` |
-    | `array_start`  | 1     | *discarded* |
-    | `value`        | 2     | `#!json 52.519444` |
-    | `value`        | 2     | `#!json 13.406667` |
-    | `array_end`    | 1     | `#!json [52.519444,13.406667]` |
-    | `object_end`   | 0     | `#!json {"location":[52.519444,13.406667],"name":"Berlin"}` |
-
-## Return value
-
-Discarding a value (i.e., returning `#!c false`) has different effects depending on the context in which function was called:
-
-- Discarded values in structured types are skipped. That is, the parser will behave as if the discarded value was never read.
-- In case a value outside a structured type is skipped, it is replaced with `#!json null`. This case happens if the top-level element is skipped.
-
-??? example
-
-    The example below demonstrates the `parse()` function with and without callback function.
-
-    ```cpp
-    --8<-- "examples/parse__string__parser_callback_t.cpp"
-    ```
-    
-    Output:
-
-    ```json
-    --8<-- "examples/parse__string__parser_callback_t.output"
-    ```

-# SAX Interface
-
-The library uses a SAX-like interface with the following functions:
-
-```plantuml
-interface json::sax_t {
-    + {abstract} bool null()
-
-    + {abstract} bool boolean(bool val)
-
-    + {abstract} bool number_integer(number_integer_t val)
-    + {abstract} bool number_unsigned(number_unsigned_t val)
-
-    + {abstract} bool number_float(number_float_t val, const string_t& s)
-
-    + {abstract} bool string(string_t& val)
-    + {abstract} bool binary(binary_t& val)
-
-    + {abstract} bool start_object(std::size_t elements)
-    + {abstract} bool end_object()
-    + {abstract} bool start_array(std::size_t elements)
-    + {abstract} bool end_array()
-    + {abstract} bool key(string_t& val)
-
-    + {abstract} bool parse_error(std::size_t position, const std::string& last_token, const json::exception& ex)
-}
-```
-
-```cpp
-// called when null is parsed
-bool null();
-
-// called when a boolean is parsed; value is passed
-bool boolean(bool val);
-
-// called when a signed or unsigned integer number is parsed; value is passed
-bool number_integer(number_integer_t val);
-bool number_unsigned(number_unsigned_t val);
-
-// called when a floating-point number is parsed; value and original string is passed
-bool number_float(number_float_t val, const string_t& s);
-
-// called when a string is parsed; value is passed and can be safely moved away
-bool string(string_t& val);
-// called when a binary value is parsed; value is passed and can be safely moved away
-bool binary(binary& val);
-
-// called when an object or array begins or ends, resp. The number of elements is passed (or -1 if not known)
-bool start_object(std::size_t elements);
-bool end_object();
-bool start_array(std::size_t elements);
-bool end_array();
-// called when an object key is parsed; value is passed and can be safely moved away
-bool key(string_t& val);
-
-// called when a parse error occurs; byte position, the last token, and an exception is passed
-bool parse_error(std::size_t position, const std::string& last_token, const json::exception& ex);
-```
-
-The return value of each function determines whether parsing should proceed.
-
-To implement your own SAX handler, proceed as follows:
-
-1. Implement the SAX interface in a class. You can use class `nlohmann::json_sax<json>` as base class, but you can also use any class where the functions described above are implemented and public.
-2. Create an object of your SAX interface class, e.g. `my_sax`.
-3. Call `#!cpp bool json::sax_parse(input, &my_sax);` where the first parameter can be any input like a string or an input stream and the second parameter is a pointer to your SAX interface.
-
-Note the `sax_parse` function only returns a `#!cpp bool` indicating the result of the last executed SAX event. It does not return `json` value - it is up to you to decide what to do with the SAX events. Furthermore, no exceptions are thrown in case of a parse error - it is up to you what to do with the exception object passed to your `parse_error` implementation. Internally, the SAX interface is used for the DOM parser (class `json_sax_dom_parser`) as well as the acceptor (`json_sax_acceptor`), see file `json_sax.hpp`.

-# Types
-
-This page gives an overview how JSON values are stored and how this can be configured.
-
-## Overview
-
-By default, JSON values are stored as follows:
-
-| JSON type | C++ type                                      |
-|-----------|-----------------------------------------------|
-| object    | `std::map<std::string, basic_json>`           |
-| array     | `std::vector<basic_json>`                     |
-| null      | `std::nullptr_t`                              |
-| string    | `std::string`                                 |
-| boolean   | `bool`                                        |
-| number    | `std::int64_t`, `std::uint64_t`, and `double` |
-
-Note there are three different types for numbers - when parsing JSON text, the best fitting type is chosen.
-
-## Storage
-
-```plantuml
-enum value_t {
-    null
-    object
-    array
-    string
-    boolean
-    number_integer
-    number_unsigned
-    number_float
-    binary
-    discarded
-}
-
-class json_value << (U,orchid) >> {
-    object_t* object
-    array_t* array
-    string_t* string
-    binary_t* binary
-    boolean_t boolean
-    number_integer_t number_integer
-    number_unsigned_t number_unsigned

-}
-
-class basic_json {
-    -- type and value --
-    value_t m_type
-    json_value m_value
-    -- derived types --
-    + <u>typedef</u> object_t
-    + <u>typedef</u> array_t
-    + <u>typedef</u> binary_t
-    + <u>typedef</u> boolean_t
-    + <u>typedef</u> number_integer_t
-    + <u>typedef</u> number_unsigned_t
-    + <u>typedef</u> number_float_t
-}
-
-basic_json .. json_value
-basic_json .. value_t
-```
-
-## Template arguments
-
-The data types to store a JSON value are derived from the template arguments passed to class `basic_json`:
-
-```cpp
-template<
-    template<typename U, typename V, typename... Args> class ObjectType = std::map,
-    template<typename U, typename... Args> class ArrayType = std::vector,
-    class StringType = std::string,
-    class BooleanType = bool,
-    class NumberIntegerType = std::int64_t,
-    class NumberUnsignedType = std::uint64_t,
-    class NumberFloatType = double,
-    template<typename U> class AllocatorType = std::allocator,
-    template<typename T, typename SFINAE = void> class JSONSerializer = adl_serializer,
-    class BinaryType = std::vector<std::uint8_t>
->
-class basic_json;
-```
-
-Type `json` is an alias for `basic_json<>` and uses the default types.
-
-From the template arguments, the following types are derived:
-
-```cpp
-using object_comparator_t = std::less<>;
-using object_t = ObjectType<StringType, basic_json, object_comparator_t,
-                   AllocatorType<std::pair<const StringType, basic_json>>>;
-
-using array_t = ArrayType<basic_json, AllocatorType<basic_json>>;
-
-using string_t = StringType;
-
-using boolean_t = BooleanType;
-
-using number_integer_t = NumberIntegerType;
-using number_unsigned_t = NumberUnsignedType;
-using number_float_t = NumberFloatType;
-
-using binary_t = nlohmann::byte_container_with_subtype<BinaryType>;
-```
-
-
-## Objects
-
-[RFC 8259](https://tools.ietf.org/html/rfc8259) describes JSON objects as follows:
-
-> An object is an unordered collection of zero or more name/value pairs, where a name is a string and a value is a string, number, boolean, null, object, or array.
-
-### Default type
-
-With the default values for *ObjectType* (`std::map`), *StringType* (`std::string`), and *AllocatorType* (`std::allocator`), the default value for `object_t` is:
-
-```cpp
-std::map<
-  std::string, // key_type
-  basic_json, // value_type
-  std::less<>, // key_compare
-  std::allocator<std::pair<const std::string, basic_json>> // allocator_type
->
-```
-
-### Behavior
-
-The choice of `object_t` influences the behavior of the JSON class. With the default type, objects have the following behavior:
-
-- When all names are unique, objects will be interoperable in the sense that all software implementations receiving that object will agree on the name-value mappings.
-- When the names within an object are not unique, it is unspecified which one of the values for a given key will be chosen. For instance, `#!json {"key": 2, "key": 1}` could be equal to either `#!json {"key": 1}` or `#!json {"key": 2}`.
-- Internally, name/value pairs are stored in lexicographical order of the names. Objects will also be serialized (see `dump`) in this order. For instance, both `#!json {"b": 1, "a": 2}` and `#!json {"a": 2, "b": 1}` will be stored and serialized as `#!json {"a": 2, "b": 1}`.
-- When comparing objects, the order of the name/value pairs is irrelevant. This makes objects interoperable in the sense that they will not be affected by these differences. For instance, `#!json {"b": 1, "a": 2}` and `#!json {"a": 2, "b": 1}` will be treated as equal.
-
-### Key order
-
-The order name/value pairs are added to the object is *not* preserved by the library. Therefore, iterating an object may return name/value pairs in a different order than they were originally stored. In fact, keys will be traversed in alphabetical order as `std::map` with `std::less` is used by default. Please note this behavior conforms to [RFC 8259](https://tools.ietf.org/html/rfc8259), because any order implements the specified "unordered" nature of JSON objects.
-
-### Limits
-
-[RFC 8259](https://tools.ietf.org/html/rfc8259) specifies:
-
-> An implementation may set limits on the maximum depth of nesting.
-
-In this class, the object's limit of nesting is not explicitly constrained. However, a maximum depth of nesting may be introduced by the compiler or runtime environment. A theoretical limit can be queried by calling the `max_size` function of a JSON object.
-
-### Storage
-
-Objects are stored as pointers in a `basic_json` type. That is, for any access to object values, a pointer of type `object_t*` must be dereferenced.
-
-
-## Arrays
-
-[RFC 8259](https://tools.ietf.org/html/rfc8259) describes JSON arrays as follows:
-
-> An array is an ordered sequence of zero or more values.
-
-### Default type
-
-With the default values for *ArrayType* (`std::vector`) and *AllocatorType* (`std::allocator`), the default value for `array_t` is:
-
-```cpp
-std::vector<
-  basic_json, // value_type
-  std::allocator<basic_json> // allocator_type
->
-```
-
-### Limits
-
-[RFC 8259](https://tools.ietf.org/html/rfc8259) specifies:
-
-> An implementation may set limits on the maximum depth of nesting.
-
-In this class, the array's limit of nesting is not explicitly constrained. However, a maximum depth of nesting may be introduced by the compiler or runtime environment. A theoretical limit can be queried by calling the `max_size` function of a JSON array.
-
-### Storage
-
-Arrays are stored as pointers in a `basic_json` type. That is, for any access to array values, a pointer of type `array_t*` must be dereferenced.
-
-
-## Strings
-
-[RFC 8259](https://tools.ietf.org/html/rfc8259) describes JSON strings as follows:
-
-> A string is a sequence of zero or more Unicode characters.
-
-Unicode values are split by the JSON class into byte-sized characters during deserialization.
-
-### Default type
-
-With the default values for *StringType* (`std::string`), the default value for `string_t` is `#!cpp std::string`.
-
-### Encoding
-
-Strings are stored in UTF-8 encoding. Therefore, functions like `std::string::size()` or `std::string::length()` return the number of **bytes** in the string rather than the number of characters or glyphs.
-
-### String comparison
-
-[RFC 8259](https://tools.ietf.org/html/rfc8259) states:
-
-> Software implementations are typically required to test names of object members for equality. Implementations that transform the textual representation into sequences of Unicode code units and then perform the comparison numerically, code unit by code unit, are interoperable in the sense that implementations will agree in all cases on equality or inequality of two strings. For example, implementations that compare strings with escaped characters unconverted may incorrectly find that `"a\\b"` and `"a\u005Cb"` are not equal.
-
-This implementation is interoperable as it does compare strings code unit by code unit.
-
-### Storage
-
-String values are stored as pointers in a `basic_json` type. That is, for any access to string values, a pointer of type `string_t*` must be dereferenced.
-
-
-## Booleans
-
-[RFC 8259](https://tools.ietf.org/html/rfc8259) implicitly describes a boolean as a type which differentiates the two literals `true` and `false`.
-
-### Default type
-
-With the default values for *BooleanType* (`#!cpp bool`), the default value for `boolean_t` is `#!cpp bool`.
-
-### Storage
-
-Boolean values are stored directly inside a `basic_json` type.
-
-## Numbers
-
-See the [number handling](number_handling.md) article for a detailed discussion on how numbers are handled by this library.
-
-[RFC 8259](https://tools.ietf.org/html/rfc8259) describes numbers as follows:
-
-> The representation of numbers is similar to that used in most programming languages. A number is represented in base 10 using decimal digits. It contains an integer component that may be prefixed with an optional minus sign, which may be followed by a fraction part and/or an exponent part. Leading zeros are not allowed. (...) Numeric values that cannot be represented in the grammar below (such as Infinity and NaN) are not permitted.
-
-This description includes both integer and floating-point numbers. However, C++ allows more precise storage if it is known whether the number is a signed integer, an unsigned integer or a floating-point number. Therefore, three different types, `number_integer_t`, `number_unsigned_t`, and `number_float_t` are used.
-
-### Default types
-
-With the default values for *NumberIntegerType* (`std::int64_t`), the default value for `number_integer_t` is `std::int64_t`.
-With the default values for *NumberUnsignedType* (`std::uint64_t`), the default value for `number_unsigned_t` is `std::uint64_t`.
-With the default values for *NumberFloatType* (`#!cpp double`), the default value for `number_float_t` is `#!cpp double`.
-
-### Default behavior
-
-- The restrictions about leading zeros is not enforced in C++. Instead, leading zeros in integer literals lead to an interpretation as octal number. Internally, the value will be stored as decimal number. For instance, the C++ integer literal `#!c 010` will be serialized to `#!c 8`. During deserialization, leading zeros yield an error.
-- Not-a-number (NaN) values will be serialized to `#!json null`.
-
-### Limits
-
-[RFC 8259](https://tools.ietf.org/html/rfc8259) specifies:
-
-> An implementation may set limits on the range and precision of numbers.
-
-When the default type is used, the maximal integer number that can be stored is `#!c 9223372036854775807` (`INT64_MAX`) and the minimal integer number that can be stored is `#!c -9223372036854775808` (`INT64_MIN`). Integer numbers that are out of range will yield over/underflow when used in a constructor. During deserialization, too large or small integer numbers will be automatically be stored as `number_unsigned_t` or `number_float_t`.
-
-When the default type is used, the maximal unsigned integer number that can be stored is `#!c 18446744073709551615` (`UINT64_MAX`) and the minimal integer number that can be stored is `#!c 0`. Integer numbers that are out of range will yield over/underflow when used in a constructor. During deserialization, too large or small integer numbers will be automatically be stored as `number_integer_t` or `number_float_t`.
-
-[RFC 8259](https://tools.ietf.org/html/rfc8259) further states:
-
-> Note that when such software is used, numbers that are integers and are in the range $[-2^{53}+1, 2^{53}-1]$ are interoperable in the sense that implementations will agree exactly on their numeric values.
-
-As this range is a subrange of the exactly supported range [`INT64_MIN`, `INT64_MAX`], this class's integer type is interoperable.
-
-[RFC 8259](https://tools.ietf.org/html/rfc8259) states:
-
-> This specification allows implementations to set limits on the range and precision of numbers accepted. Since software that implements IEEE 754-2008 binary64 (double precision) numbers is generally available and widely used, good interoperability can be achieved by implementations that expect no more precision or range than these provide, in the sense that implementations will approximate JSON numbers within the expected precision.
-
-This implementation does exactly follow this approach, as it uses double precision floating-point numbers. Note values smaller than `#!c -1.79769313486232e+308` and values greater than `#!c 1.79769313486232e+308` will be stored as NaN internally and be serialized to `#!json null`.
-
-### Storage
-
-Integer number values, unsigned integer number values, and floating-point number values are stored directly inside a `basic_json` type.

-# Number Handling
-
-This document describes how the library is handling numbers.
-
-## Background
-
-This section briefly summarizes how the JSON specification describes how numbers should be handled.
-
-### JSON number syntax
-
-JSON defines the syntax of numbers as follows:
-
-!!! quote "[RFC 8259](https://tools.ietf.org/html/rfc8259#section-6), Section 6"
-
-    The representation of numbers is similar to that used in most
-    programming languages.  A number is represented in base 10 using
-    decimal digits.  It contains an integer component that may be
-    prefixed with an optional minus sign, which may be followed by a
-    fraction part and/or an exponent part.  Leading zeros are not
-    allowed.
-
-    A fraction part is a decimal point followed by one or more digits.
-    
-    An exponent part begins with the letter E in uppercase or lowercase,
-    which may be followed by a plus or minus sign.  The E and optional
-    sign are followed by one or more digits.
-
-The following railroad diagram from [json.org](https://json.org) visualizes the number syntax:
-
-![Syntax for JSON numbers](../../images/json_syntax_number.png)
-
-### Number interoperability
-
-On number interoperability, the following remarks are made:
-
-!!! quote "[RFC 8259](https://tools.ietf.org/html/rfc8259#section-6), Section 6"
-
-    This specification allows implementations to set limits on the range
-    and precision of numbers accepted.  Since software that implements
-    IEEE 754 binary64 (double precision) numbers [IEEE754] is generally
-    available and widely used, good interoperability can be achieved by
-    implementations that expect no more precision or range than these
-    provide, in the sense that implementations will approximate JSON
-    numbers within the expected precision.  A JSON number such as 1E400
-    or 3.141592653589793238462643383279 may indicate potential
-    interoperability problems, since it suggests that the software that
-    created it expects receiving software to have greater capabilities
-    for numeric magnitude and precision than is widely available.
-    
-    Note that when such software is used, numbers that are integers and
-    are in the range $[-2^{53}+1, 2^{53}-1]$ are interoperable in the
-    sense that implementations will agree exactly on their numeric
-    values.
-
-## Library implementation
-
-This section describes how the above number specification is implemented by this library.
-
-### Number storage
-
-In the default [`json`](../../api/json.md) type, numbers are stored as `#!c std::uint64_t`, `#!c std::int64_t`, and
-`#!c double`,  respectively. Thereby, `#!c std::uint64_t` and `#!c std::int64_t` are used only if they can store the 
-number without loss of  precision. If this is impossible (e.g., if the number is too large), the number is stored as
-`#!c double`.
-
-!!! info "Notes"
-
-    - Numbers with a decimal digit or scientific notation are always stored as `#!c double`.
-    - The number types can be changed, see [Template number types](#template-number-types). 
-    - As of version 3.9.1, the conversion is realized by
-      [`std::strtoull`](https://en.cppreference.com/w/cpp/string/byte/strtoul),
-      [`std::strtoll`](https://en.cppreference.com/w/cpp/string/byte/strtol), and
-      [`std::strtod`](https://en.cppreference.com/w/cpp/string/byte/strtof), respectively.
-
-!!! example "Examples"
-
-    - Integer `#!c -12345678912345789123456789` is smaller than `#!c INT64_MIN` and will be stored as floating-point
-      number `#!c -1.2345678912345788e+25`.
-    - Integer `#!c 1E3` will be stored as floating-point number `#!c 1000.0`.
-
-### Number limits
-
-- Any 64-bit signed or unsigned integer can be stored without loss of precision.
-- Numbers exceeding the limits of `#!c double` (i.e., numbers that after conversion via
-[`std::strtod`](https://en.cppreference.com/w/cpp/string/byte/strtof) are not satisfying
-[`std::isfinite`](https://en.cppreference.com/w/cpp/numeric/math/isfinite) such as `#!c 1E400`) will throw exception
-[`json.exception.out_of_range.406`](../../home/exceptions.md#jsonexceptionout_of_range406) during parsing.
-- Floating-point numbers are rounded to the next number representable as `double`. For instance
-`#!c 3.141592653589793238462643383279` is stored as [`0x400921fb54442d18`](https://float.exposed/0x400921fb54442d18).
-This is the same behavior as the code `#!c double x = 3.141592653589793238462643383279;`.
-
-!!! success "Interoperability"
-
-    - The library interoperable with respect to the specification, because its supported range $[-2^{63}, 2^{64}-1]$ is
-      larger than the described range $[-2^{53}+1, 2^{53}-1]$.
-    - All integers outside the range $[-2^{63}, 2^{64}-1]$, as well as floating-point numbers are stored as `double`.
-      This also concurs with the specification above.
-
-### Zeros
-
-The JSON number grammar allows for different ways to express zero, and this library will store zeros differently:
-
-| Literal | Stored value and type  | Serialization |
-|---------|------------------------|---------------|
-| `0`     | `#!c std::uint64_t(0)` | `0`           |
-| `-0`    | `#!c std::int64_t(0)`  | `0`           |
-| `0.0`   | `#!c double(0.0)`      | `0.0`         |
-| `-0.0`  | `#!c double(-0.0)`     | `-0.0`        |
-| `0E0`   | `#!c double(0.0)`      | `0.0`         |
-| `-0E0`  | `#!c double(-0.0)`     | `-0.0`        |
-
-That is, `-0` is stored as a signed integer, but the serialization does not reproduce the `-`.
-
-### Number serialization
-
-- Integer numbers are serialized as is; that is, no scientific notation is used.
-- Floating-point numbers are serialized as specified by the `#!c %g` printf modifier with 
-  [`std::numeric_limits<double>::max_digits10`](https://en.cppreference.com/w/cpp/types/numeric_limits/max_digits10)
-  significant digits. The rationale is to use the shortest representation while still allow round-tripping.
-
-!!! hint "Notes regarding precision of floating-point numbers"
-
-    As described above, floating-point numbers are rounded to the nearest double and serialized with the shortest
-    representation to allow round-tripping. This can yield confusing examples:
-
-    - The serialization can have fewer decimal places than the input: `#!c 2555.5599999999999` will be serialized as
-      `#!c 2555.56`. The reverse can also be true.
-    - The serialization can be in scientific notation even if the input is not: `#!c 0.0000972439793401814` will be 
-      serialized as `#!c 9.72439793401814e-05`. The reverse can also be true: `#!c 12345E-5` will be serialized as
-      `#!c 0.12345`.
-    - Conversions from `#!c float` to `#!c double` can also introduce rounding errors:
-        ```cpp
-        float f = 0.3;
-        json j = f;
-        std::cout << j << '\n';
-        ```
-        yields `#!c 0.30000001192092896`.
-
-    All examples here can be reproduced by passing the original double value to
-
-    ```cpp
-    std::printf("%.*g\n", std::numeric_limits<double>::max_digits10, double_value);
-    ```
-
-#### NaN handling
-
-NaN (not-a-number) cannot be expressed with the number syntax described above and are in fact explicitly excluded:
-
-!!! quote "[RFC 8259](https://tools.ietf.org/html/rfc8259#section-6), Section 6"
-
-    Numeric values that cannot be represented in the grammar below (such
-    as Infinity and NaN) are not permitted.
-
-That is, there is no way to *parse* a NaN value. However, NaN values can be stored in a JSON value by assignment.
-
-This library serializes NaN values  as `#!js null`. This corresponds to the behavior of JavaScript's
-[`JSON.stringify`](https://www.w3schools.com/js/js_json_stringify.asp) function.
-
-!!! example
-
-    The following example shows how a NaN value is stored in a `json` value.
-
-    ```cpp
-    int main()
-    {
-        double val = std::numeric_limits<double>::quiet_NaN();
-        std::cout << "val=" << val << std::endl;
-        json j = val;
-        std::cout << "j=" << j.dump() << std::endl;
-        val = j;
-        std::cout << "val=" << val << std::endl;
-    }
-    ```
-    
-    output:
-    
-    ```
-    val=nan
-    j=null
-    val=nan
-    ```
-
-### Number comparison
-
-Floating-point inside JSON values numbers are compared with `#!c json::number_float_t::operator==` which is
-`#!c double::operator==` by default.
-
-!!! example "Alternative comparison functions"
-
-    To compare floating-point while respecting an epsilon, an alternative
-    [comparison function](https://github.com/mariokonrad/marnav/blob/master/include/marnav/math/floatingpoint.hpp#L34-#L39)
-    could be used, for instance
-    
-    ```cpp
-    template<typename T, typename = typename std::enable_if<std::is_floating_point<T>::value, T>::type>
-    inline bool is_same(T a, T b, T epsilon = std::numeric_limits<T>::epsilon()) noexcept
-    {
-        return std::abs(a - b) <= epsilon;
-    }
-    ```
-    Or you can self-define an operator equal function like this:
-    
-    ```cpp
-    bool my_equal(const_reference lhs, const_reference rhs)
-    {
-        const auto lhs_type lhs.type();
-        const auto rhs_type rhs.type();
-        if (lhs_type == rhs_type)
-        {
-            switch(lhs_type)
-            {
-                // self_defined case
-                case value_t::number_float:
-                    return std::abs(lhs - rhs) <= std::numeric_limits<float>::epsilon();
-        
-                // other cases remain the same with the original
-                ...
-            }
-        }
-        ...
-    }
-    ```
-    
-    (see [#703](https://github.com/nlohmann/json/issues/703) for more information.)
-    
-!!! note
-
-    NaN values never compare equal to themselves or to other NaN values. See [#514](https://github.com/nlohmann/json/issues/514).
-
-### Number conversion
-
-Just like the C++ language itself, the `get` family of functions allows conversions between unsigned and signed
-integers, and  between integers and floating-point values to integers. This behavior may be surprising.
-
-!!! warning "Unconditional number conversions"
-
-    ```cpp hl_lines="3"
-    double d = 42.3;                          // non-integer double value 42.3
-    json jd = d;                              // stores double value 42.3
-    std::int64_t i = jd.get<std::int64_t>();  // now i==42; no warning or error is produced
-    ```
-
-    Note the last line with throw a [`json.exception.type_error.302`](../../home/exceptions.md#jsonexceptiontype_error302)
-    exception if `jd` is not a numerical type, for instance a string.
-
-The rationale is twofold:
-
-1. JSON does not define a number type or precision (see [#json-specification](above)).
-2. C++ also allows to silently convert between number types.
-
-!!! success "Conditional number conversion"
-
-    The code above can be solved by explicitly checking the nature of the value with members such as
-    [`is_number_integer()`](../../api/basic_json/is_number_integer.md) or
-    [`is_number_unsigned()`](../../api/basic_json/is_number_unsigned.md):
-
-    ```cpp hl_lines="2"
-    // check if jd is really integer-valued
-    if (jd.is_number_integer())
-    {
-        // if so, do the conversion and use i
-        std::int64_t i = jd.get<std::int64_t>();
-        // ...
-    }
-    else
-    {
-        // otherwise, take appropriate action
-        // ...
-    }
-    ```
-
-    Note this approach also has the advantage that it can react on non-numerical JSON value types such as strings.
-
-    (Example taken from [#777](https://github.com/nlohmann/json/issues/777#issuecomment-459968458).)
-
-### Determine number types
-
-As the example in [Number conversion](#number_conversion) shows, there are different functions to determine the type of
-the stored number:
-
-- [`is_number()`](../../api/basic_json/is_number.md) returns `#!c true` for any number type
-- [`is_number_integer()`](../../api/basic_json/is_number_integer.md) returns `#!c true` for signed and unsigned integers
-- [`is_number_unsigned()`](../../api/basic_json/is_number_unsigned.md) returns `#!c true` for unsigned integers only
-- [`is_number_float()`](../../api/basic_json/is_number_float.md) returns `#!c true` for floating-point numbers
-- [`type_name()`](../../api/basic_json/type_name.md) returns `#!c "number"` for any number type
-- [`type()`](../../api/basic_json/type.md) returns a different enumerator of
-  [`value_t`](../../api/basic_json/value_t.md) for all number types
-
-| function                                                             | unsigned integer  | signed integer   | floating-point | string         |
-|----------------------------------------------------------------------|-------------------|------------------|----------------|----------------|
-| [`is_number()`](../../api/basic_json/is_number.md)                   | `#!c true`        | `#!c true`       | `#!c true`     | `#!c false`    |
-| [`is_number_integer()`](../../api/basic_json/is_number_integer.md)   | `#!c true`        | `#!c true`       | `#!c false`    | `#!c false`    |
-| [`is_number_unsigned()`](../../api/basic_json/is_number_unsigned.md) | `#!c true`        | `#!c false`      | `#!c false`    | `#!c false`    |
-| [`is_number_float()`](../../api/basic_json/is_number_float.md)       | `#!c false`       | `#!c false`      | `#!c true`     | `#!c false`    |
-| [`type_name()`](../../api/basic_json/type_name.md)                   | `#!c "number"`    | `#!c "number"`   | `#!c "number"` | `#!c "string"` |
-| [`type()`](../../api/basic_json/type.md)                             | `number_unsigned` | `number_integer` | `number_float` | `string`       |
-
-### Template number types
-
-The number types can be changed with template parameters.
-
-| position | number type       | default type        | possible values                                |
-|----------|-------------------|---------------------|------------------------------------------------|
-| 5        | signed integers   | `#!c std::int64_t`  | `#!c std::int32_t`, `#!c std::int16_t`, etc.   |
-| 6        | unsigned integers | `#!c std::uint64_t` | `#!c std::uint32_t`, `#!c std::uint16_t`, etc. |
-| 7        | floating-point    | `#!c double`        | `#!c float`, `#!c long double`                 |
-
-!!! info "Constraints on number types"
-
-    - The type for signed integers must be convertible from `#!c long long`. The type for floating-point numbers is used
-      in case of overflow.
-    - The type for unsigned integers must be convertible from `#!c unsigned long long`.  The type for floating-point
-      numbers is used in case of overflow.
-    - The types for signed and unsigned integers must be distinct, see
-      [#2573](https://github.com/nlohmann/json/issues/2573).
-    - Only `#!c double`, `#!c float`, and `#!c long double` are supported for floating-point numbers.
-
-!!! example
-
-    A `basic_json` type that uses `#!c long double` as floating-point type.
-
-    ```cpp hl_lines="2"
-    using json_ld = nlohmann::basic_json<std::map, std::vector, std::string, bool,
-                                         std::int64_t, std::uint64_t, long double>;
-    ```
-
-    Note values should then be parsed with `json_ld::parse` rather than `json::parse` as the latter would parse
-    floating-point values to `#!c double` before then converting them to `#!c long double`.

-# Design goals
-
-There are myriads of [JSON](https://json.org) libraries out there, and each may even have its reason to exist. Our class had these design goals:
-
-- **Intuitive syntax**. In languages such as Python, JSON feels like a first class data type. We used all the operator magic of modern C++ to achieve the same feeling in your code. Check out the [examples below](#examples), and you'll know what I mean.
-
-- **Trivial integration**. Our whole code consists of a single header file [`json.hpp`](https://github.com/nlohmann/json/blob/develop/single_include/nlohmann/json.hpp). That's it. No library, no subproject, no dependencies, no complex build system. The class is written in vanilla C++11. All in all, everything should require no adjustment of your compiler flags or project settings.
-
-- **Serious testing**. Our class is heavily [unit-tested](https://github.com/nlohmann/json/tree/develop/test/src) and covers [100%](https://coveralls.io/r/nlohmann/json) of the code, including all exceptional behavior. Furthermore, we checked with [Valgrind](http://valgrind.org) and the [Clang Sanitizers](https://clang.llvm.org/docs/index.html) that there are no memory leaks. [Google OSS-Fuzz](https://github.com/google/oss-fuzz/tree/master/projects/json) additionally runs fuzz tests against all parsers 24/7, effectively executing billions of tests so far. To maintain high quality, the project is following the [Core Infrastructure Initiative (CII) best practices](https://bestpractices.coreinfrastructure.org/projects/289).
-
-Other aspects were not so important to us:
-
-- **Memory efficiency**. Each JSON object has an overhead of one pointer (the maximal size of a union) and one enumeration element (1 byte). The default generalization uses the following C++ data types: `std::string` for strings, `int64_t`, `uint64_t` or `double` for numbers, `std::map` for objects, `std::vector` for arrays, and `bool` for Booleans. However, you can template the generalized class `basic_json` to your needs.
-
-- **Speed**. There are certainly [faster JSON libraries](https://github.com/miloyip/nativejson-benchmark#parsing-time) out there. However, if your goal is to speed up your development by adding JSON support with a single header, then this library is the way to go. If you know how to use a `std::vector` or `std::map`, you are already set.
-
-See the [contribution guidelines](https://github.com/nlohmann/json/blob/master/.github/CONTRIBUTING.md#please-dont) for more information.

-# Exceptions
-
-## Overview
-
-### Base type
-
-All exceptions inherit from class `json::exception` (which in turn inherits from `std::exception`). It is used as the base class for all exceptions thrown by the `basic_json` class. This class can hence be used as "wildcard" to catch exceptions.
-
-```plantuml
-std::exception <|-- json::exception
-json::exception <|-- json::parse_error
-json::exception <|-- json::invalid_iterator
-json::exception <|-- json::type_error
-json::exception <|-- json::out_of_range
-json::exception <|-- json::other_error
-
-interface std::exception {}
-
-class json::exception {
-    + const int id
-    + const char* what() const
-}
-
-class json::parse_error {
-    + const std::size_t byte
-}
-```
-
-### Switch off exceptions
-
-Exceptions are used widely within the library. They can, however, be switched off with either using the compiler flag `-fno-exceptions` or by defining the symbol `JSON_NOEXCEPTION`. In this case, exceptions are replaced by `abort()` calls. You can further control this behavior by defining `JSON_THROW_USER` (overriding `#!cpp throw`), `JSON_TRY_USER` (overriding `#!cpp try`), and `JSON_CATCH_USER` (overriding `#!cpp catch`).
-
-Note that `JSON_THROW_USER` should leave the current scope (e.g., by throwing or aborting), as continuing after it may yield undefined behavior.
-
-??? example
-
-    The code below switches off exceptions and creates a log entry with a detailed error message in case of errors.
-
-    ```cpp
-    #include <iostream>
-    
-    #define JSON_TRY_USER if(true)
-    #define JSON_CATCH_USER(exception) if(false)
-    #define JSON_THROW_USER(exception)                           \
-        {std::clog << "Error in " << __FILE__ << ":" << __LINE__ \
-                   << " (function " << __FUNCTION__ << ") - "    \
-                   << (exception).what() << std::endl;           \
-         std::abort();}
-    
-    #include <nlohmann/json.hpp>
-    ```
-
-Note the explanatory [`what()`](https://en.cppreference.com/w/cpp/error/exception/what) string of exceptions is not available for MSVC if exceptions are disabled, see [#2824](https://github.com/nlohmann/json/discussions/2824).
-
-### Extended diagnostic messages
-
-Exceptions in the library are thrown in the local context of the JSON value they are detected. This makes detailed diagnostics messages, and hence debugging, difficult.
-
-??? example
-
-    ```cpp
-    --8<-- "examples/diagnostics_standard.cpp"
-    ```
-    
-    Output:
-
-    ```
-    --8<-- "examples/diagnostics_standard.output"
-    ```
-
-    This exception can be hard to debug if storing the value `#!c "12"` and accessing it is further apart.
-
-To create better diagnostics messages, each JSON value needs a pointer to its parent value such that a global context (i.e., a path from the root value to the value that lead to the exception) can be created. That global context is provided as [JSON Pointer](../features/json_pointer.md).
-
-As this global context comes at the price of storing one additional pointer per JSON value and runtime overhead to maintain the parent relation, extended diagnostics are disabled by default. They can, however, be enabled by defining the preprocessor symbol [`JSON_DIAGNOSTICS`](../features/macros.md#json_diagnostics) to `1` before including `json.hpp`.
-
-??? example
-
-    ```cpp
-    --8<-- "examples/diagnostics_extended.cpp"
-    ```
-    
-    Output:
-
-    ```
-    --8<-- "examples/diagnostics_extended.output"
-    ```
-
-    Now the exception message contains a JSON Pointer `/address/housenumber` that indicates which value has the wrong type.
-
-
-## Parse errors
-
-This exception is thrown by the library when a parse error occurs. Parse errors
-can occur during the deserialization of JSON text, CBOR, MessagePack, as well
-as when using JSON Patch.
-
-Exceptions have ids 1xx.
-
-!!! info "Byte index"
-
-    Member `byte` holds the byte index of the last read character in the input
-    file.
-
-    For an input with n bytes, 1 is the index of the first character and n+1
-    is the index of the terminating null byte or the end of file. This also
-    holds true when reading a byte vector (CBOR or MessagePack).
-
-??? example
-
-    The following code shows how a `parse_error` exception can be caught.
-
-    ```cpp

-# Frequently Asked Questions (FAQ)
-
-## Known bugs
-
-### Brace initialization yields arrays
-
-!!! question
-
-    Why does
-
-    ```cpp
-    json j{true};
-    ```
-
-    and
-
-    ```cpp
-    json j(true);
-    ```
-
-    yield different results (`#!json [true]` vs. `#!json true`)?
-
-This is a known issue, and -- even worse -- the behavior differs between GCC and Clang. The "culprit" for this is the library's constructor overloads for initializer lists to allow syntax like
-
-```cpp
-json array = {1, 2, 3, 4};
-```
-
-for arrays and
-
-```cpp
-json object = {{"one", 1}, {"two", 2}}; 
-```
-
-for objects.
-
-!!! tip
-
-    To avoid any confusion and ensure portable code, **do not** use brace initialization with the types `basic_json`, `json`, or `ordered_json` unless you want to create an object or array as shown in the examples above.
-
-## Limitations
-
-### Relaxed parsing
-
-!!! question
-
-	Can you add an option to ignore trailing commas?
-
-This library does not support any feature which would jeopardize interoperability.
-
-
-### Parse errors reading non-ASCII characters
-
-!!! question "Questions"
-
-	- Why is the parser complaining about a Chinese character?
-	- Does the library support Unicode?
-	- I get an exception `[json.exception.parse_error.101] parse error at line 1, column 53: syntax error while parsing value - invalid string: ill-formed UTF-8 byte; last read: '"Testé$')"`
-
-The library supports **Unicode input** as follows:
-
-- Only **UTF-8** encoded input is supported which is the default encoding for JSON according to [RFC 8259](https://tools.ietf.org/html/rfc8259.html#section-8.1).
-- `std::u16string` and `std::u32string` can be parsed, assuming UTF-16 and UTF-32 encoding, respectively. These encodings are not supported when reading from files or other input containers.
-- Other encodings such as Latin-1 or ISO 8859-1 are **not** supported and will yield parse or serialization errors.
-- [Unicode noncharacters](http://www.unicode.org/faq/private_use.html#nonchar1) will not be replaced by the library.
-- Invalid surrogates (e.g., incomplete pairs such as `\uDEAD`) will yield parse errors.
-- The strings stored in the library are UTF-8 encoded. When using the default string type (`std::string`), note that its length/size functions return the number of stored bytes rather than the number of characters or glyphs.
-- When you store strings with different encodings in the library, calling [`dump()`](https://nlohmann.github.io/json/classnlohmann_1_1basic__json_a50ec80b02d0f3f51130d4abb5d1cfdc5.html#a50ec80b02d0f3f51130d4abb5d1cfdc5) may throw an exception unless `json::error_handler_t::replace` or `json::error_handler_t::ignore` are used as error handlers.
-
-In most cases, the parser is right to complain, because the input is not UTF-8 encoded. This is especially true for Microsoft Windows where Latin-1 or ISO 8859-1 is often the standard encoding.
-
-
-### Wide string handling
-
-!!! question
-
-    Why are wide strings (e.g., `std::wstring`) dumped as arrays of numbers?
-
-As described [above](#parse-errors-reading-non-ascii-characters), the library assumes UTF-8 as encoding.  To store a wide string, you need to change the encoding.
-
-!!! example
-
-    ```cpp
-    #include <codecvt> // codecvt_utf8
-    #include <locale>  // wstring_convert
-    
-    // encoding function
-    std::string to_utf8(std::wstring& wide_string)
-    {
-        static std::wstring_convert<std::codecvt_utf8<wchar_t>> utf8_conv;
-        return utf8_conv.to_bytes(wide_string);
-    }
-    
-    json j;
-    std::wstring ws = L"車B1234 こんにちは";
-    
-    j["original"] = ws;
-    j["encoded"] = to_utf8(ws);
-    
-    std::cout << j << std::endl;
-    ```
-    
-    The result is:
-    
-    ```json
-    {
-      "encoded": "車B1234 こんにちは",
-      "original": [36554, 66, 49, 50, 51, 52, 32, 12371, 12435, 12395, 12385, 12399]
-    }
-    ```
-
-## Exceptions
-
-### Parsing without exceptions
-
-!!! question
-
-    Is it possible to indicate a parse error without throwing an exception?
-
-Yes, see [Parsing and exceptions](../features/parsing/parse_exceptions.md).
-
-
-### Key name in exceptions
-
-!!! question
-
-	Can I get the key of the object item that caused an exception?
-
-Yes, you can. Please define the symbol [`JSON_DIAGNOSTICS`](../features/macros.md#json_diagnostics) to get [extended diagnostics messages](exceptions.md#extended-diagnostic-messages).
-
-
-## Serialization issues
-
-
-### Number precision
-
-!!! question
-
-	- It seems that precision is lost when serializing a double.
-	- Can I change the precision for floating-point serialization?
-
-The library uses `std::numeric_limits<number_float_t>::digits10` (15 for IEEE `double`s) digits for serialization. This value is sufficient to guarantee roundtripping. If one uses more than this number of digits of precision, then string -> value -> string is not guaranteed to round-trip.
-
-!!! quote "[cppreference.com](https://en.cppreference.com/w/cpp/types/numeric_limits/digits10)"
-
-	The value of `std::numeric_limits<T>::digits10` is the number of base-10 digits that can be represented by the type T without change, that is, any number with this many significant decimal digits can be converted to a value of type T and back to decimal form, without change due to rounding or overflow. 
-
-!!! tip
-
-	The website https://float.exposed gives a good insight into the internal storage of floating-point numbers.
-
-See [this section](../features/types/number_handling.md#number-serialization) on the library's number handling for more information.
-
-## Compilation issues
-
-### Android SDK
-
-!!! question
-
-	Why does the code not compile with Android SDK?
-
-Android defaults to using very old compilers and C++ libraries. To fix this, add the following to your `Application.mk`. This will switch to the LLVM C++ library, the Clang compiler, and enable C++11 and other features disabled by default.
-
-```ini
-APP_STL := c++_shared
-NDK_TOOLCHAIN_VERSION := clang3.6
-APP_CPPFLAGS += -frtti -fexceptions
-```
-
-The code compiles successfully with [Android NDK](https://developer.android.com/ndk/index.html?hl=ml), Revision 9 - 11 (and possibly later) and [CrystaX's Android NDK](https://www.crystax.net/en/android/ndk) version 10.
-
-
-### Missing STL function
-
-!!! question "Questions"
-
-	- Why do I get a compilation error `'to_string' is not a member of 'std'` (or similarly, for `strtod` or `strtof`)?
-	- Why does the code not compile with MinGW or Android SDK?
-
-This is not an issue with the code,  but rather with the compiler itself. On Android, see above to build with a newer environment.  For MinGW, please refer to [this site](http://tehsausage.com/mingw-to-string) and [this discussion](https://github.com/nlohmann/json/issues/136) for information on how to fix this bug. For Android NDK using `APP_STL := gnustl_static`, please refer to [this discussion](https://github.com/nlohmann/json/issues/219).

-
-### Summary
-
-Project [bad_json_parsers](https://github.com/lovasoa/bad_json_parsers) tested how JSON parser libraries react on **deeply nested inputs**. It turns out that this library segfaulted at a certain nesting depth. This bug was fixed with this release. **Now the parsing is only bounded by the available memory.** All changes are backward-compatible.
-
-### :bug: Bug Fixes
-
-* Fixed a bug that lead to stack overflow for deeply nested JSON values (objects, array) by changing the implementation of the destructor from a recursive to an iterative approach. #832, #1419, #1835
-
-### :hammer: Further Changes
-

-### Summary
-
-This release introduces a few convenience functions and performs a lot of house keeping (bug fixes and small improvements). All changes are backward-compatible.
-
-### :sparkles: New Features
-
-- Add overload of the **[`contains`](http://nlohmann.github.io/json/doxygen/classnlohmann_1_1basic__json_ab23b04802eb9da97dc3f664e54e09cb3.html#ab23b04802eb9da97dc3f664e54e09cb3) function** to check if a JSON pointer is valid without throwing exceptions, just like its [counterpart for object keys](http://nlohmann.github.io/json/doxygen/classnlohmann_1_1basic__json_a9286acdc0578fc66e9346323e69fc0e3.html#a9286acdc0578fc66e9346323e69fc0e3). #1600
-- Add a function **[`to_string`](http://nlohmann.github.io/json/doxygen/namespacenlohmann_a6ce645a0b8717757e096a5b5773b7a16.html#a6ce645a0b8717757e096a5b5773b7a16)** to allow for generic conversion to strings. #916 #1585
-- Add **return value for the [`emplace_back`](http://nlohmann.github.io/json/doxygen/classnlohmann_1_1basic__json_abf29131f898b05aad2c01a9c80e7a002.html#abf29131f898b05aad2c01a9c80e7a002) function**, returning a reference to the added element just like C++17 is [introducing this](https://en.cppreference.com/w/cpp/container/vector/emplace_back) for `std::vector`. #1609
-- Add info how to use the library with the **[pacman](https://wiki.archlinux.org/index.php/pacman) package manager** on MSYS2. #1670
-
-### :bug: Bug Fixes
-
-- Fix an issue where typedefs with certain names yielded a compilation error. #1642 #1643
-- Fix a conversion to `std::string_view` in the unit tests. #1634 #1639
-- Fix MSVC Debug build. #1536 #1570 #1608
-- Fix [`get_to`](https://nlohmann.github.io/json/classnlohmann_1_1basic__json_a65753c68f06639eda0d355f919564e01.html#a65753c68f06639eda0d355f919564e01) method to clear existing content before writing. #1511 #1555
-- Fix a `-Wc++17-extensions` warning. `nodiscard` attributes are now only used with Clang when `-std=c++17` is used. #1535 #1551
-
-### :zap: Improvements
-
-- Switch from [Catch](https://github.com/philsquared/Catch) to **[doctest](https://github.com/onqtam/doctest)** for the unit tests which speeds up compilation and runtime of the 112,112,308 tests.
-- Add an explicit section to the [README](https://github.com/nlohmann/json/blob/develop/README.md) about the **frequently addressed topics** [character encoding](https://github.com/nlohmann/json#character-encoding), [comments in JSON](https://github.com/nlohmann/json#comments-in-json), and the [order of object keys](https://github.com/nlohmann/json#order-of-object-keys).
-
-### :hammer: Further Changes
-
-- Use [`GNUInstallDirs`](https://cmake.org/cmake/help/v3.0/module/GNUInstallDirs.html) to set library install directories. #1673
-- Fix links in the [README](https://github.com/nlohmann/json/blob/develop/README.md). #1620 #1621 #1622 #1623 #1625
-- Mention [`json` type](http://nlohmann.github.io/json/doxygen/namespacenlohmann_a2bfd99e845a2e5cd90aeaf1b1431f474.html#a2bfd99e845a2e5cd90aeaf1b1431f474) on the [documentation start page](http://nlohmann.github.io/json/doxygen/index.html). #1616
-- Complete documentation of [`value()` function](http://nlohmann.github.io/json/doxygen/classnlohmann_1_1basic__json_adcf8ca5079f5db993820bf50036bf45d.html#adcf8ca5079f5db993820bf50036bf45d) with respect to `type_error.302` exception. #1601
-- Fix links in the documentation. #1598
-- Add regression tests for MSVC. #1543 #1570
-- Use **[CircleCI](http://circleci.com)** for [continuous integration](https://circleci.com/gh/nlohmann/json).
-- Use **[Doozer](https://doozer.io)** for [continuous integration](https://doozer.io/nlohmann/json) on Linux (CentOS, Raspbian, Fedora)
-- Add tests to check each CMake flag (`JSON_BuildTests`, `JSON_Install`, `JSON_MultipleHeaders`, `JSON_Sanitizer`, `JSON_Valgrind`, `JSON_NoExceptions`, `JSON_Coverage`).
-- Use [Hedley](https://nemequ.github.io/hedley/) to avoid re-inventing several compiler-agnostic feature macros like `JSON_DEPRECATED`, `JSON_NODISCARD`, `JSON_LIKELY`, `JSON_UNLIKELY`, `JSON_HAS_CPP_14`, or `JSON_HAS_CPP_17`. Functions taking or returning pointers are annotated accordingly when a pointer will not be null.
-- Build and run tests on [AppVeyor](https://ci.appveyor.com/project/nlohmann/json) in DEBUG and RELEASE mode.

-### Summary
-
-This release adds some **convenience functions for JSON Pointers**, introduces a [`contains`](
-http://nlohmann.github.io/json/doxygen/classnlohmann_1_1basic__json_a0a45fc740637123fdf05fef970f8be47.html#a0a45fc740637123fdf05fef970f8be47) function to check if a key is present in an object, and improves the **performance of integer serialization**. Furthermore, a lot of small bug fixes and improvements have been made. All changes are backward-compatible.
-
-### :sparkles: New Features
-
-- Overworked the public interface for JSON Pointers. The creation of JSON Pointers is simplified with [`operator/`](

-### Summary
-
-This release introduces the support for **structured bindings** and reading from **`FILE*`**. Besides, a few bugs have been fixed. All changes are backward-compatible.
-
-### :sparkles: New Features
-
-- **Structured bindings** are now supported for JSON objects and arrays via the [`items()`](https://nlohmann.github.io/json/classnlohmann_1_1basic__json_afe3e137ace692efa08590d8df40f58dd.html#afe3e137ace692efa08590d8df40f58dd) member function, so finally this code is possible:
-  ```cpp
-  for (auto& [key, val] : j.items()) {
-      std::cout << key << ':' << val << '\n';
-  }
-  ```  
-  #1388 #1391
-
-- Added support for **reading from `FILE*`** to support situations in which streams are nit available or would require too much RAM. #1370 #1392
-
-### :bug: Bug Fixes
-
-- The `eofbit` was not set for input streams when the end of a stream was reached while parsing. #1340 #1343
-- Fixed a bug in the SAX parser for BSON arrays.
-
-### :zap: Improvements
-
-- Added support for Clang 5.0.1 (PS4 version). #1341 #1342

-### Summary
-
-This release introduces three new features:
-
-- **BSON (Binary JSON)** is next to CBOR, MessagePack, and UBJSON the fourth binary (de)serialization format supported by the library.
-- **Adjustable error handlers for invalid Unicode** allows to specify the behavior when invalid byte sequences are serialized.
-- **Simplified enum/JSON mapping** with a macro in case the default mapping to integers is not desired.
-
-Furthermore, some effort has been invested in improving the **parse error messages**. Besides, a few bugs have been fixed. All changes are backward-compatible.
-
-### :sparkles: New Features
-
-- The library can read and write a subset of **[BSON](http://bsonspec.org/) (Binary JSON)**. All data types known from JSON are supported, whereas other types more tied to MongoDB such as timestamps, object ids, or binary data are currently not implemented. See [the README](https://github.com/nlohmann/json#binary-formats-bson-cbor-messagepack-and-ubjson) for examples. #1244 #1320
-- The behavior when the library encounters an invalid Unicode sequence during serialization can now be controlled by defining one of three **Unicode error handlers**: (1) throw an exception (default behavior), (2) replace invalid sequences by the Unicode replacement character (U+FFFD), or (3) ignore/filter invalid sequences. See the [documentation of the `dump` function](https://nlohmann.github.io/json/classnlohmann_1_1basic__json_a50ec80b02d0f3f51130d4abb5d1cfdc5.html#a50ec80b02d0f3f51130d4abb5d1cfdc5) for examples. #1198 #1314
-- To easily specify a user-defined **enum/JSON mapping**, a macro `NLOHMANN_JSON_SERIALIZE_ENUM` has been introduced. See the [README section](https://github.com/nlohmann/json#specializing-enum-conversion) for more information. #1208 #1323

-- fixed an issue with std::pair #1299 #1301
-- fixed an issue with std::variant #1292 #1294
-- fixed a bug in the JSON Pointer parser
-
-### :zap: Improvements
-
-- The **diagnosis messages for parse errors** have been improved: error messages now indicated line/column positions where possible (in addition to a byte count) and also the context in which the error occurred (e.g., "while parsing a JSON string"). Example: error `parse error at 2: syntax error - invalid string: control character must be escaped; last read: '<U+0009>'` is now reported as `parse error at line 1, column 2: syntax error while parsing value - invalid string: control character U+0009 (HT) must be escaped to \u0009 or \t; last read: '<U+0009>'`. #1280 #1288 #1303

-### Summary
-
-This release adds support for **GCC 4.8**. Furthermore, it adds a function [**`get_to`**](http://nlohmann.github.io/json/doxygen/classnlohmann_1_1basic__json_a8a3db7d78f74232d3a6fb8f1abf69709.html#a8a3db7d78f74232d3a6fb8f1abf69709) to write a JSON value to a passed reference. Another topic of this release was the **CMake support** which has been overworked and documented.
-
-Besides, a lot of bugs have been fixed and slight improvements have been made. All changes are backward-compatible.
-
-### :sparkles: New Features
-
-- The library can now also built with **GCC 4.8**. Though this compiler does not fully support C++11, it can successfully compile and run the test suite. Note that bug [57824](https://gcc.gnu.org/bugzilla/show_bug.cgi?id=57824) in GCC 4.8 still forbids to use multiline raw strings in arguments to macros. #1257
-- Added new function [**`get_to`**](http://nlohmann.github.io/json/doxygen/classnlohmann_1_1basic__json_a8a3db7d78f74232d3a6fb8f1abf69709.html#a8a3db7d78f74232d3a6fb8f1abf69709) to write a JSON value to a passed reference. The destination type is automatically derived which allows more succinct code compared to the `get` function. #1227 #1231
-
-### :bug: Bug Fixes
-
-- Fixed a bug in the CMake file that made `target_link_libraries` to not properly include `nlohmann_json`. #1243 #1245 #1260
-- Fixed a warning in MSVC 2017 complaining about a constexpr if. #1204 #1268 #1272
-- Fixed a bug that prevented compilation with ICPC. #755 #1222
-- Improved the SFINAE correctness to fix a bug in the conversion operator. #1237 #1238
-- Fixed a `-Wctor-dtor-privacy` warning. #1224
-- Fixed a warning on a lambda in unevaluated context. #1225 #1230
-- Fixed a bug introduced in version 3.2.0 where defining `JSON_CATCH_USER` led to duplicate macro definition of `JSON_INTERNAL_CATCH`. #1213 #1214
-- Fixed a bug that prevented compilation with Clang 3.4.2 in RHEL 7. #1179 #1249
-
-### :zap: Improvements
-
-- Added [documentation on CMake integration](https://github.com/nlohmann/json#cmake) of the library. #1270
-- Changed the CMake file to use `find_package(nlohmann_json)` without installing the library. #1202
-- Improved error messages in case `operator[]` is used with the wrong combination (json.exception.type_error.305) of JSON container type and argument type. Example: "cannot use operator[] with a string argument". #1220 #1221
-- Added a license and version information to the Meson build file. #1252
-- Removed static assertions to indicated missing `to_json` or `from_json` functions as such assertions do not play well with SFINAE. These assertions also led to problems with GMock. #960 #1212 #1228
-- The test suite now does not wait forever if run in a wrong directory and input files are not found. #1262
-- The test suite does not show deprecation warnings for deprecated functions which frequently led to confusion. #1271
-
-### :hammer: Further Changes
-
-- GCC 4.8 and Xcode 10 were added to the [continuous integration suite](https://travis-ci.org/nlohmann/json) at Travis.
-- Added [lgtm](https://lgtm.com/projects/g/nlohmann/json/context:cpp) checks to pull requests.
-- Added tests for CMake integration. #1260

-
-### Summary
-
-This release introduces a [**SAX interface**](https://nlohmann.github.io/json/structnlohmann_1_1json__sax.html) to the library. While this may be a very special feature used by only few people, it allowed to unify all functions that consumed input and created some kind of JSON value. Internally, now all existing functions like `parse`, `accept`, `from_cbor`, `from_msgpack`, and `from_ubjson` use the SAX interface with different event processors. This allowed to separate the input processing from the value generation. Furthermore, throwing an exception in case of a parse error is now optional and up to the event processor. Finally, the JSON parser is now non-recursive (meaning it does not use the call stack, but `std::vector<bool>` to track the hierarchy of structured values) which allows to process nested input more efficiently.
-
-Furthermore, the library finally is able to parse from **wide string types**. This is the first step toward opening the library from UTF-8 to UTF-16 and UTF-32.
-
-This release further fixes several bugs in the library. All changes are backward-compatible.
-

-### Summary
-
-This release fixes several bugs in the library. All changes are backward-compatible.
-
-### :bug: Bug Fixes
-
-- Fixed parsing of **CBOR strings with indefinite length** (#961). Earlier versions of this library misinterpreted the CBOR standard and rejected input with the `0x7F` start byte.
-- Fixed user-defined **conversion to vector type** (#924, #969). A wrong SFINAE check rejected code though a user-defined conversion was provided.
-- Fixed documentation of the parser behavior for **objects with duplicate keys** (#963). The exact behavior is not specified by [RFC 8259](https://tools.ietf.org/html/rfc8259) and the library now also provides no guarantee which object key is stored.
-- Added check to detect memory **overflow when parsing UBJSON containers** (#962). The optimized UBJSON format allowed for specifying an array with billions of `null` elements with a few bytes and the library did not check whether this size exceeded `max_size()`.
-
-### :hammer: Further Changes
-
-- [Code coverage](https://coveralls.io/github/nlohmann/json) is now calculated for the individual header files, allowing to find uncovered lines more quickly than by browsing through the single header version (#953, #957).
-- A Makefile target `run_benchmarks` was added to quickly build and run the benchmark suite.
-- The documentation was harmonized with respect to the header inclusion (#955). Now all examples and the README use `#include <nlohmann/json.hpp>` to allow for selecting `single_include` or `include` or whatever installation folder as include directory.
-- Added note on how to use the library with the [cget](http://cget.readthedocs.io/en/latest/) package manager (#954).

-### Summary
-
-This release adds support for the [**UBJSON**](http://ubjson.org) format and [**JSON Merge Patch**](https://tools.ietf.org/html/rfc7386). It also contains some minor changes and bug fixes. All changes are backward-compatible.
-
-### :sparkles: New features
-
-- The library now supports [**UBJSON**](http://ubjson.org) (Universal Binary JSON Specification) as binary format to read and write JSON values space-efficiently. See the [documentation overview](https://github.com/nlohmann/json/blob/develop/doc/binary_formats.md) for a comparison of the different formats CBOR, MessagePack, and UBJSON.
-- [**JSON Merge Patch**](https://tools.ietf.org/html/rfc7386) (RFC 7386) offers an intuitive means to describe patches between JSON values (#876, #877). See the documentation of [`merge_patch`](http://nlohmann.github.io/json/doxygen/classnlohmann_1_1basic__json_a0ec0cd19cce42ae6071f3cc6870ea295.html#a0ec0cd19cce42ae6071f3cc6870ea295) for more information.
-
-### :zap: Improvements
-
-- The library now uses the **Grisu2 algorithm** for printing floating-point numbers (based on the reference implementation by Florian Loitsch) which produces a short representation which is guaranteed to round-trip (#360, #935, #936).
-- The **UTF-8 handling** was further simplified by using the decoder of Björn Hoehrmann in more scenarios.
-
-### :truck: Reorganization
-
-- Though the library is released as a single header, its development got more and more complicated. With this release, the header is **split into several files** and the single-header file `json.hpp` can be generated from these development sources. In the repository, folder `include` contains the development sources and `single_include` contains the single `json.hpp` header (#700, #906, #907, #910, #911, #915, #920, #924, #925, #928, #944).
-- The split further allowed for a **forward declaration header** `include/nlohmann/json_fwd.hpp` to speed up compilation times (#314).
-
-### :hammer: Further changes
-
-- [Google Benchmark](https://github.com/google/benchmark) is now used for micro benchmarks (see `benchmarks` folder, #921).
-- The serialization (JSON and binary formats) now properly work with the libraries string template parameter, allowing for optimized string implementations to be used in constraint environments such as embedded software (#941, #950).
-- The exceptional behavior can now be overridden by defining macros `JSON_THROW_USER`, `JSON_TRY_USER`, and `JSON_CATCH_USER`, defining the behavior of `throw`, `try` and `catch`, respectively. This allows to switch off C++'s exception mechanism yet still execute user-defined code in case an error condition occurs (#938).
-- To facilitate the interplay with [flex](https://github.com/westes/flex) and [Bison](https://www.gnu.org/software/bison/), the library does not use the variable name `yytext` any more as it could clash with macro definitions (#933).
-- The library now defines `NLOHMANN_JSON_VERSION_MAJOR`, `NLOHMANN_JSON_VERSION_MINOR`, and `NLOHMANN_JSON_VERSION_PATCH` to allow for conditional compilation based on the included library version (#943, #948).
-- A compilation error with ICC has been fixed (#947).
-- Typos and links in the documentation have been fixed (#900, #930).
-- A compiler error related to incomplete types has been fixed (#919).
-- The tests form the [UTF-8 decoder stress test](http://www.cl.cam.ac.uk/~mgk25/ucs/examples/UTF-8-test.txt) have been added to the test suite.
-
-### :fire: Deprecated functions
-
-- Function [`iterator_wrapper`](http://nlohmann.github.io/json/doxygen/classnlohmann_1_1basic__json_af1592a06bc63811886ade4f9d965045e.html#af1592a06bc63811886ade4f9d965045e) has been deprecated (#874). Since its introduction, the name was up for discussion, as it was too technical. We now introduced the member function [`items()`](http://nlohmann.github.io/json/doxygen/classnlohmann_1_1basic__json_afe3e137ace692efa08590d8df40f58dd.html#afe3e137ace692efa08590d8df40f58dd) with the same semantics. `iterator_wrapper` will be removed in the next major version (i.e., 4.0.0).

-### Summary
-
-This release fixes small issues in the implementation of **JSON Pointer** and **JSON Patch**. All changes are backward-compatible.
-
-### Changes
-
-- :bug: The **"copy" operation of JSON Patch** ([RFC 6902](https://tools.ietf.org/html/rfc6902)) requests that it is an error if the target path points into a non-existing array or object (see #894 for a detailed description). This release fixes the implementation to detect such invalid target paths and throw an exception.
-- :bug: An **array index in a JSON Pointer** ([RFC 6901](https://tools.ietf.org/html/rfc6901)) must be an integer. This release fixes the implementation to throw an exception in case invalid array indices such as `10e2` are used.
-- :white_check_mark: Added the [JSON Patch tests](https://github.com/json-patch/json-patch-tests) from Byron Ruth and Mike McCabe.
-- :memo: Fixed the documentation of the [`at(ptr)` function with JSON Pointers](https://nlohmann.github.io/json/classnlohmann_1_1basic__json_a8ab61397c10f18b305520da7073b2b45.html#a8ab61397c10f18b305520da7073b2b45) to list all possible exceptions (see #888).
-- :memo: Updated the [container overview documentation](https://nlohmann.github.io/json/) (see #883).
-- :wrench: The CMake files now respect the [`BUILD_TESTING`](https://cmake.org/cmake/help/latest/module/CTest.html?highlight=build_testing) option (see #846, #885)
-- :rotating_light: Fixed some compiler warnings (see #858, #882).

-After almost a year, here is finally a new release of JSON for Modern C++, and it is a major one! As we adhere to [semantic versioning](https://semver.org), this means the release includes some breaking changes, so please read the next section carefully before you update. But don't worry, we also added a few new features and put a lot of effort into fixing a lot of bugs and straighten out a few inconsistencies.
-
-### :boom: Breaking changes
-
-This section describes changes that change the public API of the library and may require changes in code using a previous version of the library. In section "Moving from 2.x.x to 3.0.0" at the end of the release notes, we describe in detail how existing code needs to be changed.
-
-- The library now uses [**user-defined exceptions**](http://nlohmann.github.io/json/doxygen/classnlohmann_1_1basic__json_a9a0aced019cb1d65bb49703406c84970.html#a9a0aced019cb1d65bb49703406c84970) instead of re-using those defined in `<stdexcept>` (#244). This not only allows to add more information to the exceptions (every exception now has an identifier, and parse errors contain the position of the error), but also to easily catch all library exceptions with a single `catch(json::exception)`.
-- When strings with a different encoding as UTF-8 were stored in JSON values, their serialization could not be parsed by the library itself, as only UTF-8 is supported. To enforce this library limitation and improve consistency, **non-UTF-8 encoded strings now yield a `json::type_error` exception during serialization** (#838). The check for valid UTF-8 is realized with code from [Björn Hoehrmann](http://bjoern.hoehrmann.de/).
-- **NaN and infinity values can now be stored inside the JSON value** without throwing an exception. They are, however, still serialized as `null` (#388).
-- The library's iterator tag was changed from RandomAccessIterator to **[BidirectionalIterator](http://en.cppreference.com/w/cpp/concept/BidirectionalIterator)** (#593). Supporting RandomAccessIterator was incorrect as it assumed an ordering of values in a JSON objects which are unordered by definition.
-- The library does not include the standard headers `<iostream>`, `<ctype>`, and `<stdexcept>` any more. You may need to add these headers to code relying on them.
-- Removed constructor `explicit basic_json(std::istream& i, const parser_callback_t cb = nullptr)` which was deprecated in version 2.0.0 (#480).

-
-### :sparkles: New features
-
-With all this breaking and deprecation out of the way, let's talk about features!
-
-- We improved the **diagnostic information for syntax errors** (#301). Now, an exception [`json::parse_error`](http://nlohmann.github.io/json/doxygen/classnlohmann_1_1basic__json_af1efc2468e6022be6e35fc2944cabe4d.html#af1efc2468e6022be6e35fc2944cabe4d) is thrown which contains a detailed message on the error, but also a member `byte` to indicate the byte offset in the input where the error occurred.
-- We added a **non-throwing syntax check** (#458): The new `accept` function returns a Boolean indicating whether the input is proper JSON. We also added a Boolean parameter `allow_exceptions` to the existing [`parse`](http://nlohmann.github.io/json/doxygen/classnlohmann_1_1basic__json_aa9676414f2e36383c4b181fe856aa3c0.html#aa9676414f2e36383c4b181fe856aa3c0) functions to return a `discarded` value in case a syntax error occurs instead of throwing an exception.
-- An [`update`](http://nlohmann.github.io/json/doxygen/classnlohmann_1_1basic__json_a1cfa9ae5e7c2434cab4cfe69bffffe11.html#a1cfa9ae5e7c2434cab4cfe69bffffe11) function was added to **merge two JSON objects** (#428). In case you are wondering: the name was inspired by [Python](https://docs.python.org/2/library/stdtypes.html#dict.update).
-- The [`insert`](http://nlohmann.github.io/json/doxygen/classnlohmann_1_1basic__json_a1b0a4e60d56f1fe80501ed941e122892.html#a1b0a4e60d56f1fe80501ed941e122892) function now also supports an iterator range to add elements to an object.
-- The binary exchange formats **CBOR and MessagePack can now be parsed from input streams and written to output streams** (#477).
-- Input streams are now only read until the end of a JSON value instead of the end of the input (#367).
-- The serialization function [`dump`](http://nlohmann.github.io/json/doxygen/classnlohmann_1_1basic__json_a5adea76fedba9898d404fef8598aa663.html#a5adea76fedba9898d404fef8598aa663) now has two optional parameters `ensure_ascii` to **escape all non-ASCII characters** with `\uxxxx` and an `indent_char` parameter to choose whether to **indent with spaces or tabs** (#654). 
-- Added **built-in type support** for C arrays (#502), `std::pair` and `std::tuple` (#563, #614), `enum` and `enum class` (#545), `std::vector<bool>` (#494). Fixed support for `std::valarray` (#702), `std::array` (#553), and `std::map<std::string, std::string>` (#600, #607).
-
-### :hammer: Further changes
-
-Furthermore, there have been a lot of changes under the hood:
-
-- Replaced the [re2c](http://re2c.org) generated scanner by a self-coded version which allows for a better modularization of the parser and better diagnostics. To test the new scanner, we added millions (8,860,608 to be exact) of unit tests to check all valid and invalid byte sequences of the Unicode standard.
-- Google's OSS-Fuzz is still constantly fuzz-testing the library and found several issues that were fixed in this release (#497, #504, #514, #516, #518, #519, #575).
-- We now also ignore UTF-8 byte order marks when parsing from an iterator range (#602).
-- Values can be now moved from initializer lists (#663).
-- Updated to [Catch](https://github.com/catchorg/Catch2) 1.9.7. Unfortunately, Catch2 currently has some performance issues.
-- The non-exceptional paths of the library are now annotated with `__builtin_expect` to optimize branch prediction as long as no error occurs.
-- MSVC now produces a stack trace in MSVC if a `from_json` or `to_json` function was not found for a user-defined type. We also added a debug visualizer [`nlohmann_json.natvis`](https://github.com/nlohmann/json/blob/develop/nlohmann_json.natvis) for better debugging in MSVC (#844).
-- Overworked the documentation and added even more examples.
-- The build workflow now relies on CMake and CTest. Special flags can be chosen with CMake, including coverage (`JSON_Coverage`), compilation without exceptions (`JSON_NoExceptions`), LLVM sanitizers (`JSON_Sanitizer`), or execution with Valgrind (`JSON_Valgrind`).
-- Added support for package managers Meson (#576), Conan (#566), Hunter (#671, #829), and vcpkg (#753).
-- Added CI builders: Xcode 8.3, 9.0, 9.1, and 9.2; GCC 7.2; Clang 3.8, 3.9, 4.0, and 5.0; Visual Studio 2017. The library is further built with C++17 settings on the latest Clang, GCC, and MSVC version to quickly detect new issues.

-#### User-defined Exceptions
-
-There are five different exceptions inheriting from [`json::exception`](http://nlohmann.github.io/json/doxygen/classnlohmann_1_1basic__json_a9a0aced019cb1d65bb49703406c84970.html#a9a0aced019cb1d65bb49703406c84970):
-
-- [`json::parse_error`](http://nlohmann.github.io/json/doxygen/classnlohmann_1_1basic__json_af1efc2468e6022be6e35fc2944cabe4d.html#af1efc2468e6022be6e35fc2944cabe4d) for syntax errors (including the binary formats),
-- [`json::invalid_iterator`](http://nlohmann.github.io/json/doxygen/classnlohmann_1_1basic__json_ac13d32f7cbd02d616e71d8dc30dadcbf.html#ac13d32f7cbd02d616e71d8dc30dadcbf) for errors related to iterators,
-- [`json::type_error`](http://nlohmann.github.io/json/doxygen/classnlohmann_1_1basic__json_a4010e8e268fefd86da773c10318f2902.html#a4010e8e268fefd86da773c10318f2902) for errors where functions were called with the wrong JSON type,
-- [`json::out_of_range`](http://nlohmann.github.io/json/doxygen/classnlohmann_1_1basic__json_a28f7c2f087274a0012eb7a2333ee1580.html#a28f7c2f087274a0012eb7a2333ee1580) for range errors, and
-- [`json::other_error`](http://nlohmann.github.io/json/doxygen/classnlohmann_1_1basic__json_a3333a5a8714912adda33a35b369f7b3d.html#a3333a5a8714912adda33a35b369f7b3d) for miscellaneous errors.
-

-#### Handling of NaN and INF
-
-- If an overflow occurs during parsing a number from a JSON text, an exception [`json::out_of_range`](http://nlohmann.github.io/json/doxygen/classnlohmann_1_1basic__json_a28f7c2f087274a0012eb7a2333ee1580.html#a28f7c2f087274a0012eb7a2333ee1580) is thrown so that the overflow is detected early and roundtripping is guaranteed.
-
-- NaN and INF floating-point values can be stored in a JSON value and are not replaced by null. That is, the basic_json class behaves like `double` in this regard (no exception occurs). However, NaN and INF are serialized to `null`.
-
-#### Removal of deprecated functions
-
-Function `explicit basic_json(std::istream& i, const parser_callback_t cb = nullptr)` should be replaced by the `parse` function: Let `ss` be a stream and `cb` be a parse callback function.
-
-Old code:
-
-```cpp
-json j(ss, cb);
-```
-
-New code:
-
-```cpp
-json j = json::parse(ss, cb);
-```
-
-If no callback function is used, also the following code works:
-
-```cpp
-json j;
-j << ss;
-```
-
-or
-
-```cpp
-json j;
-ss >> j;
-```

-
-### Summary
-
-This release **fixes a locale-related bug in the parser**. To do so, the whole number handling (lexer, parser, and also the serialization) have been overworked. Furthermore, a lot of small changes added up that were added to this release. All changes are backward-compatible.
-
-### Changes
-- :bug: Locales that have a different character than `.` as decimal separator (e.g., the Norwegian locale `nb_NO.UTF-8`) led to truncated number parsing or parse errors. The library now has been fixed to work with **any locale**. Note that `.` is still the only valid decimal separator for JSON input.
-- :bug: Numbers like `1.0` were correctly parsed as floating-point number, but serialized as integer (`1`). Now, **floating-point numbers correctly round trip**.
-- :bug: Parsing incorrect JSON numbers with leading 0 (`0123`) could yield a [buffer overflow](https://github.com/nlohmann/json/issues/452). This is fixed now by detecting such errors directly by the lexer.
-- :bug: Constructing a JSON value from a pointer was incorrectly interpreted as a Boolean; such code will now yield a compiler error.
-- :bug: Comparing a JSON number with `0` led to a comparison with `null`. This is fixed now.
-- :bug: All throw calls are now wrapped in macros.
-- :lock: Starting during the preparation of this release (since 8 February 2017), commits and released files are **cryptographically signed** with [this GPG key](https://keybase.io/nlohmann/pgp_keys.asc?fingerprint=797167ae41c0a6d9232e48457f3cea63ae251b69). Previous releases have also been signed.
-- :sparkles: The parser for MessagePack and CBOR now supports an optional start index parameter to define a byte offset for the parser.
-- :rotating_light: Some more warnings have been fixed. With Clang, the code compiles **without warnings** with `-Weverything` (well, it needs `-Wno-documentation-unknown-command` and `-Wno-deprecated-declarations`, but you get the point).
-- :hammer: The code can be compiled easier with many Android NDKs by avoiding macros like `UINT8_MAX` which previously required defining a preprocessor macro for compilation.
-- :zap: The unit tests now compile two times faster.
-- :heavy_plus_sign: [Cotire](https://github.com/sakra/cotire) is used to speed up the build.
-- :pencil2: Fixed a lot of typos in the documentation.
-- :memo: Added a section to the README file that lists all used [third-party code/tools](https://github.com/nlohmann/json#used-third-party-tools).
-- :memo: Added a note on constructing a string value vs. parsing.
-- :white_check_mark: The test suite now contains 11202597 unit tests.
-- :memo: Improved the [Doxygen documentation](https://nlohmann.github.io/json/) by shortening the template parameters of class `basic_json`.
-- :construction_worker: Removed Doozer.
-- :construction_worker: Added Codacity.
-- :arrow_up: Upgraded Catch to version 1.7.2.

-### Summary
-
-This release introduces a means to convert from/to user-defined types. The release is backwards compatible.

-
-### Changes
-- :sparkles: The library now offers an elegant way to **convert from and to arbitrary value types**. All you need to do is to implement two functions: `to_json` and `from_json`. Then, a conversion is as simple as putting a `=` between variables. See the [README](https://github.com/nlohmann/json#arbitrary-types-conversions) for more information and examples.
-- :sparkles: **Exceptions can now be switched off.** This can be done by defining the preprocessor symbol `JSON_NOEXCEPTION` or by passing `-fno-exceptions` to your compiler. In case the code would usually thrown an exception, `abort()` is now called.
-- :sparkles: **Information on the library** can be queried with the new (static) function `meta()` which returns a JSON object with information on the version, compiler, and platform. See the [documentation]() for an example.
-- :bug: A bug in the CBOR parser was fixed which led to a buffer overflow.
-- :sparkles: The function [`type_name()`]() is now public. It allows to query the type of a JSON value as string.
-- :white_check_mark: Added the [Big List of Naughty Strings](https://github.com/minimaxir/big-list-of-naughty-strings) as test case.
-- :arrow_up: Updated to [Catch v1.6.0](https://github.com/philsquared/Catch/releases/tag/v1.6.0).
-- :memo: Some typos in the documentation have been fixed.

-
-### Summary
-
-This release fixes several security-relevant bugs in the MessagePack and CBOR parsers. The fixes are backwards compatible.
-
-### Changes
-- :bug: Fixed a lot of **bugs in the CBOR and MesssagePack parsers**. These bugs occurred if invalid input was parsed and then could lead in buffer overflows. These bugs were found with Google's [OSS-Fuzz](https://github.com/google/oss-fuzz), see #405, #407, #408, #409, #411, and #412 for more information.
-- :construction_worker: We now also use the **[Doozer](https://doozer.io) continuous integration platform**.
-- :construction_worker: The complete test suite is now also run with **Clang's address sanitizer and undefined-behavior sanitizer**.
-- :white_check_mark: Overworked **fuzz testing**; CBOR and MessagePack implementations are now fuzz-tested. Furthermore, all fuzz tests now include a round trip which ensures created output can again be properly parsed and yields the same JSON value.
-- :memo: Clarified documentation of `find()` function to always return `end()` when called on non-object value types.
-- :hammer: Moved thirdparty test code to `test/thirdparty` directory.

-
-### Summary
-
-This release implements with **[CBOR](http://cbor.io)** and **[MessagePack](http://msgpack.org)** two **binary serialization/deserialization formats**. It further contains some small fixes and improvements. The fixes are backwards compatible.

-
-### Changes
-- :sparkles: The library can now read and write the binary formats **[CBOR](http://cbor.io)** (Concise Binary Object Representation) and **[MessagePack](http://msgpack.org)**. Both formats are aimed to produce a very compact representation of JSON which can be parsed very efficiently. See the  [README file](https://github.com/nlohmann/json#binary-formats-cbor-and-messagepack) for more information and examples.
-- :fire: simplified the iteration implementation allowing to remove dozens of lines of code
-- :bug: fixed an [integer overflow error](https://github.com/nlohmann/json/issues/389) detected by [Google's OSS-Fuzz](https://github.com/google/oss-fuzz)
-- :bug: suppressed documentation warnings inside the library to facilitate compilation with `-Wdocumentation`
-- :bug: fixed an overflow detection error in the number parser
-- :memo: updated [contribution guidelines](https://github.com/nlohmann/json/blob/develop/.github/CONTRIBUTING.md) to a list of frequentely asked features that will most likely be never added to the library
-- :memo:  added a **table of contents** to the [README file](https://github.com/nlohmann/json/blob/develop/README.md) to add some structure
-- :memo: mentioned the many [examples](https://github.com/nlohmann/json/tree/develop/doc/examples) and the [documentation](https://nlohmann.github.io/json/) in the [README file]()
-- :hammer: split [unit tests](https://github.com/nlohmann/json/tree/develop/test/src) into individual independent binaries to speed up compilation and testing

-### Summary
-
-This release combines a lot of small fixes and improvements. The fixes are backwards compatible.
-
-### Changes
-- :bug: fixed a bug that froze the parser if a passed file was not found (now, `std::invalid_argument` is thrown)
-- :bug: fixed a bug that lead to an error of a file at EOF was parsed again (now, `std::invalid_argument` is thrown)
-- :sparkles: the well known functions [`emplace`](http://nlohmann.github.io/json/doxygen/classnlohmann_1_1basic__json_a602f275f0359ab181221384989810604.html#a602f275f0359ab181221384989810604) and [`emplace_back`](http://nlohmann.github.io/json/doxygen/classnlohmann_1_1basic__json_af8a435033327d9237da414afc1cce513.html#af8a435033327d9237da414afc1cce513) have been added to JSON values and work as expected
-- :zap: improved the performance of the serialization (`dump` function)
-- :zap: improved the performance of the deserialization (parser)
-- :construction_worker: some continuous integration images at [Travis](https://travis-ci.org/nlohmann/json) were added and retired; see [here](https://github.com/nlohmann/json#supported-compilers) for the current continuous integration setup

-### Summary
-
-This release fixes a few bugs in the JSON parser found in the [Parsing JSON is a Minefield 💣](http://seriot.ch/parsing_json.html) article. The fixes are backwards compatible.
-
-### Changes
-- The article [Parsing JSON is a Minefield 💣](http://seriot.ch/parsing_json.html) discusses a lot of pitfalls of the JSON specification. When investigating the published test cases, a few bugs in the library were found and fixed:
-  - Files with less than 5 bytes can now be parsed without error.
-  - The library now properly rejects any file encoding other than UTF-8. Furthermore, incorrect surrogate pairs are properly detected and rejected.
-  - The library now accepts all but one "yes" test (y_string_utf16.json): UTF-16 is not supported.
-  - The library rejects all but one "no" test (n_number_then_00.json): Null bytes are treated as end of file instead of an error. This allows to parse input from null-terminated strings.
-- The string length passed to a user-defined string literal is now exploited to choose a more efficient constructor.
-- A few grammar mistakes in the README file have been fixed.

-
-### Summary
-
-This release fixes the semantics of `operator[]` for JSON Pointers (see below). This fix is backwards compatible.
-
-### Changes
-- **`operator[]` for JSON Pointers** now behaves like the other versions of `operator[]` and transforms `null` values into objects or arrays if required. This allows to created nested structures like `j["/foo/bar/2"] = 17` (yielding `{"foo": "bar": [null, null, 17]}`) without problems.
-- overworked a helper SFINAE function
-- fixed some documentation issues
-- fixed the CMake files to allow to run the test suite outside the main project directory
-- restored test coverage to 100%.

-
-### Summary
-
-This release combines a lot of small fixes and improvements. The release is backwards compatible.
-
-### Changes
-- The **parser/deserialization functions have been generalized** to process any contiguous sequence of 1-byte elements (e.g., `char`, `unsigned char`, `uint8_t`). This includes all kind of string representations (string literals, char arrays, `std::string`, `const char*`), contiguous containers (C-style arrays, `std::vector`, `std::array`, `std::valarray`, `std::initializer_list`). User-defined containers providing random-access iterator access via `std::begin` and `std::end` can be used as well. See the documentation ([1](https://nlohmann.github.io/json/classnlohmann_1_1basic__json_ace63ac4eb1dd7251a259d32e397461a3.html#ace63ac4eb1dd7251a259d32e397461a3), [2](https://nlohmann.github.io/json/classnlohmann_1_1basic__json_a90f05d55d9d0702c075cd281fd0d85ae.html#a90f05d55d9d0702c075cd281fd0d85ae), [3](https://nlohmann.github.io/json/classnlohmann_1_1basic__json_aeffd70f622f8f2a51fd3d95af64b63a7.html#aeffd70f622f8f2a51fd3d95af64b63a7), [4](https://nlohmann.github.io/json/classnlohmann_1_1basic__json_aa8dca2e91a6301c36890f844e64f0023.html#aa8dca2e91a6301c36890f844e64f0023)) for more information. Note that contiguous storage cannot be checked at compile time; if any of the parse functions are called with a noncompliant container, the behavior is undefined and will most likely yield segmentation violation. The preconditions are enforced by an assertion unless the library is compiled with preprocessor symbol `NDEBUG`.
-- As a general remark on **assertions**: The library uses assertions to preclude undefined behavior. A [prominent example](https://github.com/nlohmann/json/issues/289) for this is the `operator[]` for const JSON objects. The behavior of this const version of the operator is undefined if the given key does not exist in the JSON object, because unlike the non-const version, it cannot add a `null` value at the given key. Assertions can be switched of by defining the preprocessor symbol `NDEBUG`. See the [documentation of `assert`](http://en.cppreference.com/w/cpp/error/assert) for more information.
-- In the course of cleaning up the parser/deserialization functions, the constructor [`basic_json(std::istream&, const parser_callback_t)`](https://nlohmann.github.io/json/classnlohmann_1_1basic__json_a32350263eb105764844c5a85e156a255.html#a32350263eb105764844c5a85e156a255) has been **deprecated** and will be deleted with the next major release 3.0.0 to unify the interface of the library. Deserialization will be done by stream operators or by calling one of the `parse` functions. That is, calls like `json j(i);` for an input stream `i` need to be replaced by `json j = json::parse(i);`. Compilers will produce a deprecation warning if client code uses this function.
-- Minor improvements:
-  - Improved the performance of the serialization by avoiding the re-creation of a locale object.
-  - Fixed two MSVC warnings. Compiling the test suite with `/Wall` now only warns about non-inlined functions (C4710) and the deprecation of the constructor from input-stream (C4996).
-- Some project internals:
-  - <img align="right" src="https://bestpractices.coreinfrastructure.org/assets/questions_page_badge-17b338c0e8528d695d8676e23f39f17ca2b89bb88176370803ee69aeebcb5be4.png"> The project has qualified for the [Core Infrastructure Initiative Best Practices Badge](https://bestpractices.coreinfrastructure.org/projects/289). While most requirements where already satisfied, some led to a more explicit documentation of quality-ensuring procedures. For instance, static analysis is now executed with every commit on the build server. Furthermore, the [contribution guidelines document](https://github.com/nlohmann/json/blob/develop/.github/CONTRIBUTING.md) how to communicate security issues privately.
-  - The test suite has been overworked and split into several files to allow for faster compilation and analysis. The execute the test suite, simply execute `make check`.
-  - The continuous integration with [Travis](https://travis-ci.org/nlohmann/json) was extended with Clang versions 3.6.0 to 3.8.1 and now includes 18 different compiler/OS combinations.
-  - An 11-day run of [American fuzzy lop](http://lcamtuf.coredump.cx/afl/) checked 962 million inputs on the parser and found no issue.

-
-### Summary
-
-This release combines a lot of small fixes and improvements. The release is backwards compatible.
-
-### Changes
-- The **parser** has been overworked, and a lot of small issues have been fixed:
-  - Improved parser performance by avoiding recursion and using move semantics for the return value.
-  - Unescaped control characters `\x10`-`\x1f` are not accepted any more.
-  - Fixed a bug in the parser when reading from an input stream.
-  - Improved test case coverage for UTF-8 parsing: now, all valid Unicode code points are tested both escaped and unescaped.
-  - The precision of output streams is now preserved by the parser.
-- Started to check the **code correctness** by proving termination of important loops. Furthermore, individual assertions have been replaced by a more systematic function which checks the class invariants. Note that assertions should be switched off in production by defining the preprocessor macro `NDEBUG`, see the [documentation of `assert`](http://en.cppreference.com/w/cpp/error/assert).
-- A lot of **code cleanup**: removed unused headers, fixed some compiler warnings, and fixed a build error for Windows-based Clang builds.
-- Added some compile-time checks:
-  - Unsupported compilers are rejected during compilation with an `#error` command.
-  - Static assertion prohibits code with incompatible pointer types used in `get_ptr()`.
-- Improved the [documentation](https://nlohmann.github.io/json/), and adjusted the documentation script to choose the correct version of `sed`.
-- Replaced a lot of "raw loops" by STL functions like `std::all_of`, `std::for_each`, or `std::accumulate`. This facilitates reasoning about termination of loops and sometimes allowed to simplify functions to a single return statement.
-- Implemented a `value()` function for JSON pointers (similar to `at` function).
-- The Homebrew formula (see [Integration](https://github.com/nlohmann/json#integration)) is now tested for all Xcode builds (6.1 - 8.x) with Travis.
-- Avoided output to `std::cout` in the test cases.

-
-### Summary
-
-This release fixes a performance regression in the JSON serialization (function `dump()`). This fix is backwards compatible.
-
-### Changes
-- The locale of the output stream (or the internal string stream if a JSON value is serialized to a string) is now adjusted once for the whole serialization instead of for each floating-point number.
-- The locale of an output stream is now correctly reset to the previous value by the JSON library.

-
-### Summary
-
-This release adds several features such as JSON Pointers, JSON Patch, or support for 64 bit unsigned integers. Furthermore, several (subtle) bugs have been fixed.
-
-As `noexcept` and `constexpr` specifier have been added to several functions, the public API has effectively been changed in a (potential) non-backwards compatible manner. As we adhere to [Semantic Versioning](http://semver.org), this calls for a new major version, so say hello to 2️⃣.0️⃣.0️⃣.
-
-### Changes
-- 🔟 A JSON value now uses `uint64_t` (default value for template parameter `NumberUnsignedType`) as data type for **unsigned integer** values. This type is used automatically when an unsigned number is parsed. Furthermore, constructors, conversion operators and an `is_number_unsigned()` test have been added.
--  👉 **JSON Pointer** ([RFC 6901](https://tools.ietf.org/html/rfc6901)) support: A JSON Pointer is a string (similar to an XPath expression) to address a value inside a structured JSON value. JSON Pointers can be used in `at()` and `operator[]` functions. Furthermore, JSON values can be “flattened” to key/value pairs using `flatten()` where each key is a JSON Pointer. The original value can be restored by “unflattening” the flattened value using `unflatten()`.
-- 🏥 **JSON Patch** ([RFC 6902](https://tools.ietf.org/html/rfc6902)) support. A JSON Patch is a JSON value that describes the required edit operations (add, change, remove, …) to transform a JSON value into another one. A JSON Patch can be created with function `diff(const basic_json&)` and applied with `patch(const basic_json&)`. Note the created patches use a rather primitive algorithm so far and leave room for improvement.
-- 🇪🇺 The code is now **locale-independent**: Floating-point numbers are always serialized with a period (`.`) as decimal separator and ignores different settings from the locale.
-- 🍺 **Homebrew** support: Install the library with `brew tap nlohmann/json && brew install nlohmann_json`.
-- Added constructor to create a JSON value by parsing a `std::istream` (e.g., `std::stringstream` or `std::ifstream`).
-- Added **`noexcept`** specifier to `basic_json(boolean_t)`, `basic_json(const number_integer_t)`, `basic_json(const int)`, `basic_json(const number_float_t)`, iterator functions (`begin()`, `end()`, etc.)
-- When parsing numbers, the sign of `0.0` (vs. `-0.0`) is preserved.
-- Improved MSVC 2015, Android, and MinGW support. See [README](https://github.com/nlohmann/json#supported-compilers) for more information.
-- Improved test coverage (added 2,225,386 tests).
-- Removed some misuses of `std::move`.
-- Fixed several compiler warnings.
-- Improved error messages from JSON parser.
-- Updated to [`re2c`](http://re2c.org) to version 0.16 to use a minimal DFAs for the lexer.
-- Updated test suite to use [Catch](https://github.com/philsquared/Catch) version 1.5.6.
-- Made type getters (`is_number`, etc.) and const value access `constexpr`.
-- Functions `push_back` and `operator+=` now work with key/value pairs passed as initializer list, e.g. `j_object += {"key", 1}`.
-- Overworked `CMakeLists.txt` to make it easier to integrate the library into other projects.
-
-### Notes
-- Parser error messages are still very vague and contain no information on the error location.
-- The implemented `diff` function is rather primitive and does not create minimal diffs.
-- The name of function `iteration_wrapper` may change in the future and the function will be deprecated in the next release.
-- Roundtripping (i.e., parsing a JSON value from a string, serializing it, and comparing the strings) of floating-point numbers is not 100% accurate. Note that [RFC 8259](https://tools.ietf.org/html/rfc8259) defines no format to internally represent numbers and states not requirement for roundtripping. Nevertheless, benchmarks like [Native JSON Benchmark](https://github.com/miloyip/nativejson-benchmark) treat roundtripping deviations as conformance errors.

-
-### Summary
-
-This release fixes several small bugs and adds functionality in a backwards-compatible manner. Compared to the [last version (1.0.0)](https://github.com/nlohmann/json/releases/tag/v1.0.0), the following changes have been made:
-
-### Changes
-- _Fixed_: **Floating-point numbers** are now serialized and deserialized properly such that rountripping works in more cases. [#185, #186, #190, #191, #194]
-- _Added_: The code now contains **assertions** to detect undefined behavior during development. As the standard function `assert` is used, the assertions can be switched off by defining the preprocessor symbol `NDEBUG` during compilation. [#168]
-- _Added_: It is now possible to get a **reference** to the stored values via the newly added function `get_ref()`. [#128, #184]
-- _Fixed_: Access to object values via keys (**`operator[]`**) now works with all kind of string representations. [#171, #189]
-- _Fixed_: The code now compiles again with **Microsoft Visual Studio 2015**. [#144, #167, #188]
-- _Fixed_: All required headers are now included.
-- _Fixed_: Typos and other small issues. [#162, #166,  #175, #177, #179, #180]
-
-### Notes
-
-There are still known open issues (#178, #187) which will be fixed in version 2.0.0. However, these fixes will require a small API change and will not be entirely backwards-compatible.

-# CMake
-
-## Integration
-
-You can also use the `nlohmann_json::nlohmann_json` interface target in CMake.  This target populates the appropriate usage requirements for `INTERFACE_INCLUDE_DIRECTORIES` to point to the appropriate include directories and `INTERFACE_COMPILE_FEATURES` for the necessary C++11 flags.
-
-### External
-
-To use this library from a CMake project, you can locate it directly with `find_package()` and use the namespaced imported target from the generated package configuration:
-
-```cmake
-# CMakeLists.txt
-find_package(nlohmann_json 3.2.0 REQUIRED)
-...
-add_library(foo ...)
-...
-target_link_libraries(foo PRIVATE nlohmann_json::nlohmann_json)
-```
-
-The package configuration file, `nlohmann_jsonConfig.cmake`, can be used either from an install tree or directly out of the build tree.
-
-### Embedded
-
-To embed the library directly into an existing CMake project, place the entire source tree in a subdirectory and call `add_subdirectory()` in your `CMakeLists.txt` file:
-
-```cmake
-# If you only include this third party in PRIVATE source files, you do not
-# need to install it when your main project gets installed.
-# set(JSON_Install OFF CACHE INTERNAL "")
-
-# Don't use include(nlohmann_json/CMakeLists.txt) since that carries with it
-# unintended consequences that will break the build.  It's generally
-# discouraged (although not necessarily well documented as such) to use
-# include(...) for pulling in other CMake projects anyways.
-add_subdirectory(nlohmann_json)
-...
-add_library(foo ...)
-...
-target_link_libraries(foo PRIVATE nlohmann_json::nlohmann_json)
-```
-
-### Embedded (FetchContent)
-
-Since CMake v3.11,
-[FetchContent](https://cmake.org/cmake/help/v3.11/module/FetchContent.html) can
-be used to automatically download the repository as a dependency at configure type.
-
-Example:
-```cmake
-include(FetchContent)
-
-FetchContent_Declare(json
-  GIT_REPOSITORY https://github.com/nlohmann/json
-  GIT_TAG v3.7.3)
-
-FetchContent_GetProperties(json)
-if(NOT json_POPULATED)
-  FetchContent_Populate(json)
-  add_subdirectory(${json_SOURCE_DIR} ${json_BINARY_DIR} EXCLUDE_FROM_ALL)
-endif()
-
-target_link_libraries(foo PRIVATE nlohmann_json::nlohmann_json)
-```
-
-!!! Note
-	The repository <https://github.com/nlohmann/json> download size is quite large.
-	You might want to depend on a smaller repository. For instance, you might want to replace the URL above by
-	<https://github.com/ArthurSonzogni/nlohmann_json_cmake_fetchcontent>.
-
-### Supporting Both
-
-To allow your project to support either an externally supplied or an embedded JSON library, you can use a pattern akin to the following:
-
-``` cmake
-# Top level CMakeLists.txt
-project(FOO)
-...
-option(FOO_USE_EXTERNAL_JSON "Use an external JSON library" OFF)
-...
-add_subdirectory(thirdparty)
-...
-add_library(foo ...)
-...
-# Note that the namespaced target will always be available regardless of the
-# import method
-target_link_libraries(foo PRIVATE nlohmann_json::nlohmann_json)
-```
-```cmake
-# thirdparty/CMakeLists.txt
-...
-if(FOO_USE_EXTERNAL_JSON)
-  find_package(nlohmann_json 3.2.0 REQUIRED)
-else()
-  set(JSON_BuildTests OFF CACHE INTERNAL "")
-  add_subdirectory(nlohmann_json)
-endif()
-...
-```
-
-`thirdparty/nlohmann_json` is then a complete copy of this source tree.
-
-## CMake Options
-
-### `JSON_BuildTests`
-
-Build the unit tests when [`BUILD_TESTING`](https://cmake.org/cmake/help/latest/command/enable_testing.html) is enabled. This option is `ON` by default if the library's CMake project is the top project. That is, when integrating the library as described above, the test suite is not built unless explicitly switched on with this option.
-
-### `JSON_CI`
-
-Enable CI build targets. The exact targets are used during the several CI steps and are subject to change without notice. This option is `OFF` by default.
-
-### `JSON_Diagnostics`
-
-Enable [extended diagnostic messages](../home/exceptions.md#extended-diagnostic-messages) by defining macro [`JSON_DIAGNOSTICS`](../features/macros.md#json_diagnostics). This option is `OFF` by default.
-
-### `JSON_FastTests`
-
-Skip expensive/slow test suites. This option is `OFF` by default. Depends on `JSON_BuildTests`.
-
-### `JSON_ImplicitConversions`
-
-Enable implicit conversions by defining macro [`JSON_USE_IMPLICIT_CONVERSIONS`](../features/macros.md#json_use_implicit_conversions). This option is `ON` by default.
-
-### `JSON_Install`
-
-Install CMake targets during install step. This option is `ON` by default if the library's CMake project is the top project.
-
-### `JSON_MultipleHeaders`
-
-Use non-amalgamated version of the library. This option is `OFF` by default.
-
-### `JSON_SystemInclude`
-
-Treat the library headers like system headers (i.e., adding `SYSTEM` to the [`target_include_directories`](https://cmake.org/cmake/help/latest/command/target_include_directories.html) call) to checks for this library by tools like Clang-Tidy. This option is `OFF` by default.
-
-### `JSON_Valgrind`
-
-Execute test suite with [Valgrind](https://valgrind.org). This option is `OFF` by default. Depends on `JSON_BuildTests`.

-
-to the files you want to process JSON and set the necessary switches to enable C++11 (e.g., `-std=c++11` for GCC and Clang).
-
-You can further use file [`include/nlohmann/json_fwd.hpp`](https://github.com/nlohmann/json/blob/develop/include/nlohmann/json_fwd.hpp) for forward-declarations. The installation of `json_fwd.hpp` (as part of CMake's install step), can be achieved by setting `-DJSON_MultipleHeaders=ON`.

-# Package Managers
-
-Throughout this page, we will describe how to compile the example file `example.cpp` below.
-
-```cpp
---8<-- "integration/example.cpp"
-```
-
-## Homebrew
-
-If you are using OS X and [Homebrew](http://brew.sh), just type
-
-```sh
-brew install nlohmann-json
-```
-
-and you're set. If you want the bleeding edge rather than the latest release, use
-
-```sh
-brew install nlohmann-json --HEAD
-```
-
-instead. See [nlohmann-json](https://formulae.brew.sh/formula/nlohmann-json) for more information.
-
-??? example
-
-	1. Create the following file:
-
-		=== "example.cpp"
-
-			```cpp
-			--8<-- "integration/example.cpp"
-			```
-
-	2. Install the package
-
-		```sh
-		brew install nlohmann-json
-		```
-
-	3. Determine the include path, which defaults to `/usr/local/Cellar/nlohmann-json/$version/include`, where `$version` is the version of the library, e.g. `3.7.3`. The path of the library can be determined with
-
-		```sh
-		brew list nlohmann-json
-		```
-
-	4. Compile the code. For instance, the code can be compiled using Clang with
-
-		```sh
-		clang++ example.cpp -I/usr/local/Cellar/nlohmann-json/3.7.3/include -std=c++11 -o example
-		```
-
-## Meson
-
-If you are using the [Meson Build System](http://mesonbuild.com), add this source tree as a [meson subproject](https://mesonbuild.com/Subprojects.html#using-a-subproject). You may also use the `include.zip` published in this project's [Releases](https://github.com/nlohmann/json/releases) to reduce the size of the vendored source tree. Alternatively, you can get a wrap file by downloading it from [Meson WrapDB](https://wrapdb.mesonbuild.com/nlohmann_json), or simply use `meson wrap install nlohmann_json`. Please see the meson project for any issues regarding the packaging.
-
-The provided `meson.build` can also be used as an alternative to cmake for installing `nlohmann_json` system-wide in which case a pkg-config file is installed. To use it, simply have your build system require the `nlohmann_json` pkg-config dependency. In Meson, it is preferred to use the [`dependency()`](https://mesonbuild.com/Reference-manual.html#dependency) object with a subproject fallback, rather than using the subproject directly.
-
-## Conan
-
-If you are using [Conan](https://www.conan.io/) to manage your dependencies, merely add `nlohmann_json/x.y.z` to your `conanfile`'s requires, where `x.y.z` is the release version you want to use. Please file issues [here](https://github.com/conan-io/conan-center-index/issues) if you experience problems with the packages.
-
-??? example
-
-	1. Create the following files:
-
-		=== "Conanfile.txt"
-			
-			```ini
-			--8<-- "integration/conan/Conanfile.txt"
-			```
-
-		=== "CMakeLists.txt"
-
-		    ```cmake
-			--8<-- "integration/conan/CMakeLists.txt"
-		    ```
-
-		=== "example.cpp"
-
-			```cpp
-			--8<-- "integration/conan/example.cpp"
-			```
-
-
-	2. Build:
-
-		```sh
-		mkdir build
-		cd build
-		conan install ..
-		cmake ..
-		cmake --build .
-		```
-
-## Spack

-HISTORY for Lua 5.1
-
-* Changes from version 5.0 to 5.1
-  -------------------------------
-  Language:
-  + new module system.
-  + new semantics for control variables of fors.
-  + new semantics for setn/getn.
-  + new syntax/semantics for varargs.
-  + new long strings and comments.
-  + new `mod' operator (`%')
-  + new length operator #t
-  + metatables for all types
-  API:
-  + new functions: lua_createtable, lua_get(set)field, lua_push(to)integer.
-  + user supplies memory allocator (lua_open becomes lua_newstate).
-  + luaopen_* functions must be called through Lua.
-  Implementation:
-  + new configuration scheme via luaconf.h.
-  + incremental garbage collection.
-  + better handling of end-of-line in the lexer.
-  + fully reentrant parser (new Lua function `load')
-  + better support for 64-bit machines.
-  + native loadlib support for Mac OS X.
-  + standard distribution in only one library (lualib.a merged into lua.a)
-
-* Changes from version 4.0 to 5.0
-  -------------------------------
-  Language:
-  + lexical scoping.
-  + Lua coroutines.
-  + standard libraries now packaged in tables.
-  + tags replaced by metatables and tag methods replaced by metamethods,
-    stored in metatables.
-  + proper tail calls.
-  + each function can have its own global table, which can be shared.
-  + new __newindex metamethod, called when we insert a new key into a table.
-  + new block comments: --[[ ... ]].
-  + new generic for.
-  + new weak tables.
-  + new boolean type.
-  + new syntax "local function".
-  + (f()) returns the first value returned by f.
-  + {f()} fills a table with all values returned by f.
-  + \n ignored in [[\n .
-  + fixed and-or priorities.
-  + more general syntax for function definition (e.g. function a.x.y:f()...end).
-  + more general syntax for function calls (e.g. (print or write)(9)).
-  + new functions (time/date, tmpfile, unpack, require, load*, etc.).
-  API:
-  + chunks are loaded by using lua_load; new luaL_loadfile and luaL_loadbuffer.
-  + introduced lightweight userdata, a simple "void*" without a metatable.
-  + new error handling protocol: the core no longer prints error messages;
-    all errors are reported to the caller on the stack.
-  + new lua_atpanic for host cleanup.
-  + new, signal-safe, hook scheme.
-  Implementation:
-  + new license: MIT.
-  + new, faster, register-based virtual machine.
-  + support for external multithreading and coroutines.
-  + new and consistent error message format.
-  + the core no longer needs "stdio.h" for anything (except for a single
-    use of sprintf to convert numbers to strings).
-  + lua.c now runs the environment variable LUA_INIT, if present. It can
-    be "@filename", to run a file, or the chunk itself.
-  + support for user extensions in lua.c.
-    sample implementation given for command line editing.
-  + new dynamic loading library, active by default on several platforms.
-  + safe garbage-collector metamethods.
-  + precompiled bytecodes checked for integrity (secure binary dostring).
-  + strings are fully aligned.
-  + position capture in string.find.
-  + read('*l') can read lines with embedded zeros.
-
-* Changes from version 3.2 to 4.0
-  -------------------------------
-  Language:
-  + new "break" and "for" statements (both numerical and for tables).
-  + uniform treatment of globals: globals are now stored in a Lua table.
-  + improved error messages.
-  + no more '$debug': full speed *and* full debug information.
-  + new read form: read(N) for next N bytes.
-  + general read patterns now deprecated.
-    (still available with -DCOMPAT_READPATTERNS.)
-  + all return values are passed as arguments for the last function
-    (old semantics still available with -DLUA_COMPAT_ARGRET)
-  + garbage collection tag methods for tables now deprecated.
-  + there is now only one tag method for order.
-  API:
-  + New API: fully re-entrant, simpler, and more efficient.
-  + New debug API.
-  Implementation:
-  + faster than ever: cleaner virtual machine and new hashing algorithm.
-  + non-recursive garbage-collector algorithm.
-  + reduced memory usage for programs with many strings.
-  + improved treatment for memory allocation errors.
-  + improved support for 16-bit machines (we hope).
-  + code now compiles unmodified as both ANSI C and C++.
-  + numbers in bases other than 10 are converted using strtoul.
-  + new -f option in Lua to support #! scripts.
-  + luac can now combine text and binaries.
-
-* Changes from version 3.1 to 3.2
-  -------------------------------
-  + redirected all output in Lua's core to _ERRORMESSAGE and _ALERT.
-  + increased limit on the number of constants and globals per function
-    (from 2^16 to 2^24).
-  + debugging info (lua_debug and hooks) moved into lua_state and new API
-    functions provided to get and set this info.
-  + new debug lib gives full debugging access within Lua.
-  + new table functions "foreachi", "sort", "tinsert", "tremove", "getn".
-  + new io functions "flush", "seek".
-
-* Changes from version 3.0 to 3.1
-  -------------------------------
-  + NEW FEATURE: anonymous functions with closures (via "upvalues").
-  + new syntax:
-    - local variables in chunks.
-    - better scope control with DO block END.
-    - constructors can now be also written: { record-part; list-part }.
-    - more general syntax for function calls and lvalues, e.g.:
-      f(x).y=1
-      o:f(x,y):g(z)
-      f"string" is sugar for f("string")
-  + strings may now contain arbitrary binary data (e.g., embedded zeros).
-  + major code re-organization and clean-up; reduced module interdependecies.
-  + no arbitrary limits on the total number of constants and globals.
-  + support for multiple global contexts.
-  + better syntax error messages.
-  + new traversal functions "foreach" and "foreachvar".
-  + the default for numbers is now double.
-    changing it to use floats or longs is easy.
-  + complete debug information stored in pre-compiled chunks.
-  + sample interpreter now prompts user when run interactively, and also
-    handles control-C interruptions gracefully.
-
-* Changes from version 2.5 to 3.0
-  -------------------------------
-  + NEW CONCEPT: "tag methods".
-    Tag methods replace fallbacks as the meta-mechanism for extending the
-    semantics of Lua. Whereas fallbacks had a global nature, tag methods
-    work on objects having the same tag (e.g., groups of tables).
-    Existing code that uses fallbacks should work without change.
-  + new, general syntax for constructors {[exp] = exp, ... }.
-  + support for handling variable number of arguments in functions (varargs).
-  + support for conditional compilation ($if ... $else ... $end).
-  + cleaner semantics in API simplifies host code.
-  + better support for writing libraries (auxlib.h).
-  + better type checking and error messages in the standard library.
-  + luac can now also undump.
-
-* Changes from version 2.4 to 2.5
-  -------------------------------
-  + io and string libraries are now based on pattern matching;
-    the old libraries are still available for compatibility
-  + dofile and dostring can now return values (via return statement)
-  + better support for 16- and 64-bit machines
-  + expanded documentation, with more examples
-
-* Changes from version 2.2 to 2.4
-  -------------------------------
-  + external compiler creates portable binary files that can be loaded faster
-  + interface for debugging and profiling
-  + new "getglobal" fallback
-  + new functions for handling references to Lua objects
-  + new functions in standard lib
-  + only one copy of each string is stored
-  + expanded documentation, with more examples
-
-* Changes from version 2.1 to 2.2
-  -------------------------------
-  + functions now may be declared with any "lvalue" as a name
-  + garbage collection of functions
-  + support for pipes
-
-* Changes from version 1.1 to 2.1
-  -------------------------------
-  + object-oriented support
-  + fallbacks
-  + simplified syntax for tables
-  + many internal improvements

-INSTALL for Lua 5.1
-
-* Building Lua
-  ------------
-  Lua is built in the src directory, but the build process can be
-  controlled from the top-level Makefile.
-
-  Building Lua on Unix systems should be very easy. First do "make" and
-  see if your platform is listed. If so, just do "make xxx", where xxx
-  is your platform name. The platforms currently supported are:
-    aix ansi bsd freebsd generic linux macosx mingw posix solaris
-
-  If your platform is not listed, try the closest one or posix, generic,
-  ansi, in this order.
-
-  See below for customization instructions and for instructions on how
-  to build with other Windows compilers.
-
-  If you want to check that Lua has been built correctly, do "make test"
-  after building Lua. Also, have a look at the example programs in test.
-
-* Installing Lua
-  --------------
-  Once you have built Lua, you may want to install it in an official
-  place in your system. In this case, do "make install". The official
-  place and the way to install files are defined in Makefile. You must
-  have the right permissions to install files.
-
-  If you want to build and install Lua in one step, do "make xxx install",
-  where xxx is your platform name.
-
-  If you want to install Lua locally, then do "make local". This will
-  create directories bin, include, lib, man, and install Lua there as
-  follows:
-
-    bin:	lua luac
-    include:	lua.h luaconf.h lualib.h lauxlib.h lua.hpp
-    lib:	liblua.a
-    man/man1:	lua.1 luac.1
-
-  These are the only directories you need for development.
-
-  There are man pages for lua and luac, in both nroff and html, and a
-  reference manual in html in doc, some sample code in test, and some
-  useful stuff in etc. You don't need these directories for development.
-
-  If you want to install Lua locally, but in some other directory, do
-  "make install INSTALL_TOP=xxx", where xxx is your chosen directory.
-
-  See below for instructions for Windows and other systems.
-
-* Customization
-  -------------
-  Three things can be customized by editing a file:
-    - Where and how to install Lua -- edit Makefile.
-    - How to build Lua -- edit src/Makefile.
-    - Lua features -- edit src/luaconf.h.
-
-  You don't actually need to edit the Makefiles because you may set the
-  relevant variables when invoking make.
-
-  On the other hand, if you need to select some Lua features, you'll need
-  to edit src/luaconf.h. The edited file will be the one installed, and
-  it will be used by any Lua clients that you build, to ensure consistency.
-
-  We strongly recommend that you enable dynamic loading. This is done
-  automatically for all platforms listed above that have this feature
-  (and also Windows). See src/luaconf.h and also src/Makefile.
-
-* Building Lua on Windows and other systems
-  -----------------------------------------
-  If you're not using the usual Unix tools, then the instructions for
-  building Lua depend on the compiler you use. You'll need to create
-  projects (or whatever your compiler uses) for building the library,
-  the interpreter, and the compiler, as follows:
-
-  library:	lapi.c lcode.c ldebug.c ldo.c ldump.c lfunc.c lgc.c llex.c
-		lmem.c lobject.c lopcodes.c lparser.c lstate.c lstring.c
-		ltable.c ltm.c lundump.c lvm.c lzio.c
-		lauxlib.c lbaselib.c ldblib.c liolib.c lmathlib.c loslib.c
-		ltablib.c lstrlib.c loadlib.c linit.c
-
-  interpreter:	library, lua.c
-
-  compiler:	library, luac.c print.c
-
-  If you use Visual Studio .NET, you can use etc/luavs.bat in its
-  "Command Prompt".
-
-  If all you want is to build the Lua interpreter, you may put all .c files
-  in a single project, except for luac.c and print.c. Or just use etc/all.c.
-
-  To use Lua as a library in your own programs, you'll need to know how to
-  create and use libraries with your compiler.
-
-  As mentioned above, you may edit luaconf.h to select some features before
-  building Lua.

-
-* What is Lua?
-  ------------
-  Lua is a powerful, light-weight programming language designed for extending
-  applications. Lua is also frequently used as a general-purpose, stand-alone
-  language. Lua is free software.
-
-  For complete information, visit Lua's web site at http://www.lua.org/ .
-  For an executive summary, see http://www.lua.org/about.html .
-
-  Lua has been used in many different projects around the world.
-  For a short list, see http://www.lua.org/uses.html .
-
-* Availability
-  ------------
-  Lua is freely available for both academic and commercial purposes.
-  See COPYRIGHT and http://www.lua.org/license.html for details.
-  Lua can be downloaded at http://www.lua.org/download.html .
-
-* Installation
-  ------------
-  Lua is implemented in pure ANSI C, and compiles unmodified in all known
-  platforms that have an ANSI C compiler. In most Unix-like platforms, simply
-  do "make" with a suitable target. See INSTALL for detailed instructions.
-
-* Origin
-  ------
-  Lua is developed at Lua.org, a laboratory of the Department of Computer
-  Science of PUC-Rio (the Pontifical Catholic University of Rio de Janeiro
-  in Brazil).
-  For more information about the authors, see http://www.lua.org/authors.html .

-.SH NAME
-lua \- Lua interpreter
-.SH SYNOPSIS
-.B lua
-[
-.I options
-]
-[
-.I script
-[
-.I args
-]
-]
-.SH DESCRIPTION
-.B lua
-is the stand-alone Lua interpreter.
-It loads and executes Lua programs,
-either in textual source form or
-in precompiled binary form.
-(Precompiled binaries are output by
-.BR luac ,
-the Lua compiler.)
-.B lua
-can be used as a batch interpreter and also interactively.
-.LP
-The given
-.I options
-(see below)
-are executed and then
-the Lua program in file
-.I script
-is loaded and executed.
-The given
-.I args
-are available to
-.I script
-as strings in a global table named
-.BR arg .
-If these arguments contain spaces or other characters special to the shell,
-then they should be quoted
-(but note that the quotes will be removed by the shell).
-The arguments in
-.B arg
-start at 0,
-which contains the string
-.RI ' script '.
-The index of the last argument is stored in
-.BR arg.n .
-The arguments given in the command line before
-.IR script ,
-including the name of the interpreter,
-are available in negative indices in
-.BR arg .
-.LP
-At the very start,
-before even handling the command line,
-.B lua
-executes the contents of the environment variable
-.BR LUA_INIT ,
-if it is defined.
-If the value of
-.B LUA_INIT
-is of the form
-.RI '@ filename ',
-then
-.I filename
-is executed.
-Otherwise, the string is assumed to be a Lua statement and is executed.
-.LP
-Options start with
-.B '\-'
-and are described below.
-You can use
-.B "'\--'"
-to signal the end of options.
-.LP
-If no arguments are given,
-then
-.B "\-v \-i"
-is assumed when the standard input is a terminal;
-otherwise,
-.B "\-"
-is assumed.
-.LP
-In interactive mode,
-.B lua
-prompts the user,
-reads lines from the standard input,
-and executes them as they are read.
-If a line does not contain a complete statement,
-then a secondary prompt is displayed and
-lines are read until a complete statement is formed or
-a syntax error is found.
-So, one way to interrupt the reading of an incomplete statement is
-to force a syntax error:
-adding a
-.B ';' 
-in the middle of a statement is a sure way of forcing a syntax error
-(except inside multiline strings and comments; these must be closed explicitly).
-If a line starts with
-.BR '=' ,
-then
-.B lua
-displays the values of all the expressions in the remainder of the
-line. The expressions must be separated by commas.
-The primary prompt is the value of the global variable
-.BR _PROMPT ,
-if this value is a string;
-otherwise, the default prompt is used.
-Similarly, the secondary prompt is the value of the global variable
-.BR _PROMPT2 .
-So,
-to change the prompts,
-set the corresponding variable to a string of your choice.
-You can do that after calling the interpreter
-or on the command line
-(but in this case you have to be careful with quotes
-if the prompt string contains a space; otherwise you may confuse the shell.)
-The default prompts are "> " and ">> ".
-.SH OPTIONS
-.TP
-.B \-
-load and execute the standard input as a file,
-that is,
-not interactively,
-even when the standard input is a terminal.
-.TP
-.BI \-e " stat"
-execute statement
-.IR stat .
-You need to quote
-.I stat 
-if it contains spaces, quotes,
-or other characters special to the shell.
-.TP
-.B \-i
-enter interactive mode after
-.I script
-is executed.
-.TP
-.BI \-l " name"
-call
-.BI require(' name ')
-before executing
-.IR script .
-Typically used to load libraries.
-.TP
-.B \-v
-show version information.

-<H2>DESCRIPTION</H2>
-<B>luac</B>
-is the Lua compiler.
-It translates programs written in the Lua programming language
-into binary files that can be later loaded and executed.
-<P>
-The main advantages of precompiling chunks are:
-faster loading,
-protecting source code from accidental user changes,
-and
-off-line syntax checking.
-<P>
-Precompiling does not imply faster execution
-because in Lua chunks are always compiled into bytecodes before being executed.
-<B>luac</B>
-simply allows those bytecodes to be saved in a file for later execution.
-<P>
-Precompiled chunks are not necessarily smaller than the corresponding source.
-The main goal in precompiling is faster loading.
-<P>
-The binary files created by
-<B>luac</B>
-are portable only among architectures with the same word size and byte order.
-<P>
-<B>luac</B>
-produces a single output file containing the bytecodes
-for all source files given.
-By default,
-the output file is named
-<B>luac.out</B>,
-but you can change this with the
-<B>-o</B>
-option.
-<P>
-In the command line,
-you can mix
-text files containing Lua source and
-binary files containing precompiled chunks.
-This is useful because several precompiled chunks,
-even from different (but compatible) platforms,
-can be combined into a single precompiled chunk.
-<P>
-You can use
-<B>'-'</B>
-to indicate the standard input as a source file
-and
-<B>'--'</B>
-to signal the end of options
-(that is,
-all remaining arguments will be treated as files even if they start with
-<B>'-'</B>).
-<P>
-The internal format of the binary files produced by
-<B>luac</B>
-is likely to change when a new version of Lua is released.
-So,
-save the source files of all Lua programs that you precompile.
-<P>
-<H2>OPTIONS</H2>
-Options must be separate.
-<P>
-<B>-l</B>
-produce a listing of the compiled bytecode for Lua's virtual machine.
-Listing bytecodes is useful to learn about Lua's virtual machine.
-If no files are given, then
-<B>luac</B>
-loads
-<B>luac.out</B>
-and lists its contents.
-<P>
-<B>-o </B><I>file</I>
-output to
-<I>file</I>,
-instead of the default
-<B>luac.out</B>.
-(You can use
-<B>'-'</B>
-for standard output,
-but not on platforms that open standard output in text mode.)
-The output file may be a source file because
-all files are loaded before the output file is written.
-Be careful not to overwrite precious files.
-<P>
-<B>-p</B>
-load files but do not generate any output file.
-Used mainly for syntax checking and for testing precompiled chunks:
-corrupted files will probably generate errors when loaded.
-Lua always performs a thorough integrity test on precompiled chunks.
-Bytecode that passes this test is completely safe,
-in the sense that it will not break the interpreter.
-However,
-there is no guarantee that such code does anything sensible.
-(None can be given, because the halting problem is unsolvable.)
-If no files are given, then
-<B>luac</B>
-loads
-<B>luac.out</B>
-and tests its contents.
-No messages are displayed if the file passes the integrity test.
-<P>
-<B>-s</B>
-strip debug information before writing the output file.
-This saves some space in very large chunks,
-but if errors occur when running a stripped chunk,

-<h1>1 - <a name="1">Introduction</a></h1>
-
-<p>
-Lua is an extension programming language designed to support
-general procedural programming with data description
-facilities.
-It also offers good support for object-oriented programming,
-functional programming, and data-driven programming.
-Lua is intended to be used as a powerful, light-weight
-scripting language for any program that needs one.
-Lua is implemented as a library, written in <em>clean</em> C
-(that is, in the common subset of ANSI&nbsp;C and C++).
-
-
-<p>
-Being an extension language, Lua has no notion of a "main" program:
-it only works <em>embedded</em> in a host client,
-called the <em>embedding program</em> or simply the <em>host</em>.
-This host program can invoke functions to execute a piece of Lua code,
-can write and read Lua variables,
-and can register C&nbsp;functions to be called by Lua code.
-Through the use of C&nbsp;functions, Lua can be augmented to cope with
-a wide range of different domains,
-thus creating customized programming languages sharing a syntactical framework.
-The Lua distribution includes a sample host program called <code>lua</code>,
-which uses the Lua library to offer a complete, stand-alone Lua interpreter.
-
-
-<p>
-Lua is free software,
-and is provided as usual with no guarantees,
-as stated in its license.
-The implementation described in this manual is available
-at Lua's official web site, <code>www.lua.org</code>.
-
-
-<p>
-Like any other reference manual,
-this document is dry in places.
-For a discussion of the decisions behind the design of Lua,
-see the technical papers available at Lua's web site.
-For a detailed introduction to programming in Lua,
-see Roberto's book, <em>Programming in Lua (Second Edition)</em>.
-
-
-
-<h1>2 - <a name="2">The Language</a></h1>
-
-<p>
-This section describes the lexis, the syntax, and the semantics of Lua.
-In other words,
-this section describes
-which tokens are valid,
-how they can be combined,
-and what their combinations mean.
-
-
-<p>
-The language constructs will be explained using the usual extended BNF notation,
-in which
-{<em>a</em>}&nbsp;means&nbsp;0 or more <em>a</em>'s, and
-[<em>a</em>]&nbsp;means an optional <em>a</em>.
-Non-terminals are shown like non-terminal,
-keywords are shown like <b>kword</b>,
-and other terminal symbols are shown like `<b>=</b>&acute;.
-The complete syntax of Lua can be found in <a href="#8">&sect;8</a>
-at the end of this manual.
-
-
-
-<h2>2.1 - <a name="2.1">Lexical Conventions</a></h2>
-
-<p>
-<em>Names</em>
-(also called <em>identifiers</em>)
-in Lua can be any string of letters,
-digits, and underscores,
-not beginning with a digit.
-This coincides with the definition of names in most languages.
-(The definition of letter depends on the current locale:
-any character considered alphabetic by the current locale
-can be used in an identifier.)
-Identifiers are used to name variables and table fields.
-
-
-<p>
-The following <em>keywords</em> are reserved
-and cannot be used as names:
-
-
-<pre>
-     and       break     do        else      elseif
-     end       false     for       function  if
-     in        local     nil       not       or
-     repeat    return    then      true      until     while
-</pre>
-
-<p>
-Lua is a case-sensitive language:
-<code>and</code> is a reserved word, but <code>And</code> and <code>AND</code>
-are two different, valid names.
-As a convention, names starting with an underscore followed by
-uppercase letters (such as <a href="#pdf-_VERSION"><code>_VERSION</code></a>)
-are reserved for internal global variables used by Lua.
-
-
-<p>
-The following strings denote other tokens:
-
-<pre>
-     +     -     *     /     %     ^     #
-     ==    ~=    &lt;=    &gt;=    &lt;     &gt;     =
-     (     )     {     }     [     ]
-     ;     :     ,     .     ..    ...
-</pre>
-
-<p>
-<em>Literal strings</em>
-can be delimited by matching single or double quotes,
-and can contain the following C-like escape sequences:
-'<code>\a</code>' (bell),
-'<code>\b</code>' (backspace),
-'<code>\f</code>' (form feed),
-'<code>\n</code>' (newline),
-'<code>\r</code>' (carriage return),
-'<code>\t</code>' (horizontal tab),
-'<code>\v</code>' (vertical tab),
-'<code>\\</code>' (backslash),
-'<code>\"</code>' (quotation mark [double quote]),
-and '<code>\'</code>' (apostrophe [single quote]).
-Moreover, a backslash followed by a real newline
-results in a newline in the string.
-A character in a string can also be specified by its numerical value
-using the escape sequence <code>\<em>ddd</em></code>,
-where <em>ddd</em> is a sequence of up to three decimal digits.
-(Note that if a numerical escape is to be followed by a digit,
-it must be expressed using exactly three digits.)
-Strings in Lua can contain any 8-bit value, including embedded zeros,
-which can be specified as '<code>\0</code>'.
-
-
-<p>
-Literal strings can also be defined using a long format
-enclosed by <em>long brackets</em>.
-We define an <em>opening long bracket of level <em>n</em></em> as an opening
-square bracket followed by <em>n</em> equal signs followed by another
-opening square bracket.
-So, an opening long bracket of level&nbsp;0 is written as <code>[[</code>,
-an opening long bracket of level&nbsp;1 is written as <code>[=[</code>,
-and so on.
-A <em>closing long bracket</em> is defined similarly;
-for instance, a closing long bracket of level&nbsp;4 is written as <code>]====]</code>.
-A long string starts with an opening long bracket of any level and
-ends at the first closing long bracket of the same level.
-Literals in this bracketed form can run for several lines,
-do not interpret any escape sequences,
-and ignore long brackets of any other level.
-They can contain anything except a closing bracket of the proper level.
-
-
-<p>
-For convenience,
-when the opening long bracket is immediately followed by a newline,
-the newline is not included in the string.
-As an example, in a system using ASCII
-(in which '<code>a</code>' is coded as&nbsp;97,
-newline is coded as&nbsp;10, and '<code>1</code>' is coded as&nbsp;49),
-the five literal strings below denote the same string:
-
-<pre>
-     a = 'alo\n123"'
-     a = "alo\n123\""
-     a = '\97lo\10\04923"'
-     a = [[alo
-     123"]]
-     a = [==[
-     alo
-     123"]==]
-</pre>
-
-<p>
-A <em>numerical constant</em> can be written with an optional decimal part
-and an optional decimal exponent.
-Lua also accepts integer hexadecimal constants,
-by prefixing them with <code>0x</code>.
-Examples of valid numerical constants are
-
-<pre>
-     3   3.0   3.1416   314.16e-2   0.31416E1   0xff   0x56
-</pre>
-
-<p>
-A <em>comment</em> starts with a double hyphen (<code>--</code>)
-anywhere outside a string.
-If the text immediately after <code>--</code> is not an opening long bracket,
-the comment is a <em>short comment</em>,
-which runs until the end of the line.
-Otherwise, it is a <em>long comment</em>,
-which runs until the corresponding closing long bracket.
-Long comments are frequently used to disable code temporarily.
-

-
-<h2>2.2 - <a name="2.2">Values and Types</a></h2>
-
-<p>
-Lua is a <em>dynamically typed language</em>.
-This means that
-variables do not have types; only values do.
-There are no type definitions in the language.
-All values carry their own type.
-
-
-<p>
-All values in Lua are <em>first-class values</em>.
-This means that all values can be stored in variables,
-passed as arguments to other functions, and returned as results.
-
-
-<p>
-There are eight basic types in Lua:
-<em>nil</em>, <em>boolean</em>, <em>number</em>,
-<em>string</em>, <em>function</em>, <em>userdata</em>,
-<em>thread</em>, and <em>table</em>.
-<em>Nil</em> is the type of the value <b>nil</b>,
-whose main property is to be different from any other value;
-it usually represents the absence of a useful value.
-<em>Boolean</em> is the type of the values <b>false</b> and <b>true</b>.
-Both <b>nil</b> and <b>false</b> make a condition false;
-any other value makes it true.
-<em>Number</em> represents real (double-precision floating-point) numbers.
-(It is easy to build Lua interpreters that use other
-internal representations for numbers,
-such as single-precision float or long integers;
-see file <code>luaconf.h</code>.)
-<em>String</em> represents arrays of characters.
-
-Lua is 8-bit clean:
-strings can contain any 8-bit character,
-including embedded zeros ('<code>\0</code>') (see <a href="#2.1">&sect;2.1</a>).
-
-
-<p>
-Lua can call (and manipulate) functions written in Lua and
-functions written in C
-(see <a href="#2.5.8">&sect;2.5.8</a>).
-
-
-<p>
-The type <em>userdata</em> is provided to allow arbitrary C&nbsp;data to
-be stored in Lua variables.
-This type corresponds to a block of raw memory
-and has no pre-defined operations in Lua,
-except assignment and identity test.
-However, by using <em>metatables</em>,
-the programmer can define operations for userdata values
-(see <a href="#2.8">&sect;2.8</a>).
-Userdata values cannot be created or modified in Lua,
-only through the C&nbsp;API.
-This guarantees the integrity of data owned by the host program.
-
-
-<p>
-The type <em>thread</em> represents independent threads of execution
-and it is used to implement coroutines (see <a href="#2.11">&sect;2.11</a>).
-Do not confuse Lua threads with operating-system threads.
-Lua supports coroutines on all systems,
-even those that do not support threads.
-
-
-<p>
-The type <em>table</em> implements associative arrays,
-that is, arrays that can be indexed not only with numbers,
-but with any value (except <b>nil</b>).
-Tables can be <em>heterogeneous</em>;
-that is, they can contain values of all types (except <b>nil</b>).
-Tables are the sole data structuring mechanism in Lua;
-they can be used to represent ordinary arrays,
-symbol tables, sets, records, graphs, trees, etc.
-To represent records, Lua uses the field name as an index.
-The language supports this representation by
-providing <code>a.name</code> as syntactic sugar for <code>a["name"]</code>.
-There are several convenient ways to create tables in Lua
-(see <a href="#2.5.7">&sect;2.5.7</a>).
-
-
-<p>
-Like indices,
-the value of a table field can be of any type (except <b>nil</b>).
-In particular,
-because functions are first-class values,
-table fields can contain functions.
-Thus tables can also carry <em>methods</em> (see <a href="#2.5.9">&sect;2.5.9</a>).
-
-
-<p>
-Tables, functions, threads, and (full) userdata values are <em>objects</em>:
-variables do not actually <em>contain</em> these values,
-only <em>references</em> to them.
-Assignment, parameter passing, and function returns
-always manipulate references to such values;
-these operations do not imply any kind of copy.
-
-
-<p>
-The library function <a href="#pdf-type"><code>type</code></a> returns a string describing the type
-of a given value.
-
-
-
-<h3>2.2.1 - <a name="2.2.1">Coercion</a></h3>
-
-<p>
-Lua provides automatic conversion between
-string and number values at run time.
-Any arithmetic operation applied to a string tries to convert
-this string to a number, following the usual conversion rules.
-Conversely, whenever a number is used where a string is expected,
-the number is converted to a string, in a reasonable format.
-For complete control over how numbers are converted to strings,
-use the <code>format</code> function from the string library
-(see <a href="#pdf-string.format"><code>string.format</code></a>).
-
-
-
-
-
-
-
-<h2>2.3 - <a name="2.3">Variables</a></h2>
-
-<p>
-Variables are places that store values.
-
-There are three kinds of variables in Lua:
-global variables, local variables, and table fields.
-
-
-<p>
-A single name can denote a global variable or a local variable
-(or a function's formal parameter,
-which is a particular kind of local variable):
-
-<pre>
-	var ::= Name
-</pre><p>
-Name denotes identifiers, as defined in <a href="#2.1">&sect;2.1</a>.
-
-
-<p>
-Any variable is assumed to be global unless explicitly declared
-as a local (see <a href="#2.4.7">&sect;2.4.7</a>).
-Local variables are <em>lexically scoped</em>:
-local variables can be freely accessed by functions
-defined inside their scope (see <a href="#2.6">&sect;2.6</a>).
-
-
-<p>
-Before the first assignment to a variable, its value is <b>nil</b>.
-
-
-<p>
-Square brackets are used to index a table:
-
-<pre>
-	var ::= prefixexp `<b>[</b>&acute; exp `<b>]</b>&acute;
-</pre><p>
-The meaning of accesses to global variables 
-and table fields can be changed via metatables.
-An access to an indexed variable <code>t[i]</code> is equivalent to
-a call <code>gettable_event(t,i)</code>.
-(See <a href="#2.8">&sect;2.8</a> for a complete description of the
-<code>gettable_event</code> function.
-This function is not defined or callable in Lua.
-We use it here only for explanatory purposes.)
-
-
-<p>
-The syntax <code>var.Name</code> is just syntactic sugar for
-<code>var["Name"]</code>:
-
-<pre>
-	var ::= prefixexp `<b>.</b>&acute; Name
-</pre>
-
-<p>
-All global variables live as fields in ordinary Lua tables,
-called <em>environment tables</em> or simply
-<em>environments</em> (see <a href="#2.9">&sect;2.9</a>).
-Each function has its own reference to an environment,
-so that all global variables in this function
-will refer to this environment table.
-When a function is created,
-it inherits the environment from the function that created it.
-To get the environment table of a Lua function,
-you call <a href="#pdf-getfenv"><code>getfenv</code></a>.
-To replace it,
-you call <a href="#pdf-setfenv"><code>setfenv</code></a>.
-(You can only manipulate the environment of C&nbsp;functions
-through the debug library; (see <a href="#5.9">&sect;5.9</a>).)
-
-
-<p>
-An access to a global variable <code>x</code>
-is equivalent to <code>_env.x</code>,
-which in turn is equivalent to
-
-<pre>
-     gettable_event(_env, "x")
-</pre><p>
-where <code>_env</code> is the environment of the running function.
-(See <a href="#2.8">&sect;2.8</a> for a complete description of the
-<code>gettable_event</code> function.
-This function is not defined or callable in Lua.
-Similarly, the <code>_env</code> variable is not defined in Lua.
-We use them here only for explanatory purposes.)
-
-
-
-
-
-<h2>2.4 - <a name="2.4">Statements</a></h2>
-
-<p>
-Lua supports an almost conventional set of statements,
-similar to those in Pascal or C.
-This set includes
-assignments, control structures, function calls,
-and variable declarations.
-
-
-
-<h3>2.4.1 - <a name="2.4.1">Chunks</a></h3>
-
-<p>
-The unit of execution of Lua is called a <em>chunk</em>.
-A chunk is simply a sequence of statements,
-which are executed sequentially.
-Each statement can be optionally followed by a semicolon:
-
-<pre>
-	chunk ::= {stat [`<b>;</b>&acute;]}
-</pre><p>
-There are no empty statements and thus '<code>;;</code>' is not legal.
-
-
-<p>
-Lua handles a chunk as the body of an anonymous function 
-with a variable number of arguments
-(see <a href="#2.5.9">&sect;2.5.9</a>).
-As such, chunks can define local variables,
-receive arguments, and return values.
-
-
-<p>
-A chunk can be stored in a file or in a string inside the host program.
-To execute a chunk,
-Lua first pre-compiles the chunk into instructions for a virtual machine,
-and then it executes the compiled code
-with an interpreter for the virtual machine.
-
-
-<p>
-Chunks can also be pre-compiled into binary form;
-see program <code>luac</code> for details.
-Programs in source and compiled forms are interchangeable;
-Lua automatically detects the file type and acts accordingly.
-
-
-
-
-
-
-<h3>2.4.2 - <a name="2.4.2">Blocks</a></h3><p>
-A block is a list of statements;
-syntactically, a block is the same as a chunk:
-
-<pre>
-	block ::= chunk
-</pre>
-
-<p>
-A block can be explicitly delimited to produce a single statement:
-
-<pre>
-	stat ::= <b>do</b> block <b>end</b>
-</pre><p>
-Explicit blocks are useful
-to control the scope of variable declarations.
-Explicit blocks are also sometimes used to
-add a <b>return</b> or <b>break</b> statement in the middle
-of another block (see <a href="#2.4.4">&sect;2.4.4</a>).
-
-
-
-
-
-<h3>2.4.3 - <a name="2.4.3">Assignment</a></h3>
-
-<p>
-Lua allows multiple assignments.
-Therefore, the syntax for assignment
-defines a list of variables on the left side
-and a list of expressions on the right side.
-The elements in both lists are separated by commas:
-
-<pre>
-	stat ::= varlist `<b>=</b>&acute; explist
-	varlist ::= var {`<b>,</b>&acute; var}
-	explist ::= exp {`<b>,</b>&acute; exp}
-</pre><p>
-Expressions are discussed in <a href="#2.5">&sect;2.5</a>.
-
-
-<p>
-Before the assignment,
-the list of values is <em>adjusted</em> to the length of
-the list of variables.
-If there are more values than needed,
-the excess values are thrown away.
-If there are fewer values than needed,
-the list is extended with as many  <b>nil</b>'s as needed.
-If the list of expressions ends with a function call,
-then all values returned by that call enter the list of values,
-before the adjustment
-(except when the call is enclosed in parentheses; see <a href="#2.5">&sect;2.5</a>).
-
-
-<p>
-The assignment statement first evaluates all its expressions
-and only then are the assignments performed.
-Thus the code
-
-<pre>
-     i = 3
-     i, a[i] = i+1, 20
-</pre><p>
-sets <code>a[3]</code> to 20, without affecting <code>a[4]</code>
-because the <code>i</code> in <code>a[i]</code> is evaluated (to 3)
-before it is assigned&nbsp;4.
-Similarly, the line
-
-<pre>
-     x, y = y, x
-</pre><p>
-exchanges the values of <code>x</code> and <code>y</code>,
-and
-
-<pre>
-     x, y, z = y, z, x
-</pre><p>
-cyclically permutes the values of <code>x</code>, <code>y</code>, and <code>z</code>.
-
-
-<p>
-The meaning of assignments to global variables
-and table fields can be changed via metatables.
-An assignment to an indexed variable <code>t[i] = val</code> is equivalent to
-<code>settable_event(t,i,val)</code>.
-(See <a href="#2.8">&sect;2.8</a> for a complete description of the
-<code>settable_event</code> function.
-This function is not defined or callable in Lua.
-We use it here only for explanatory purposes.)
-
-
-<p>
-An assignment to a global variable <code>x = val</code>
-is equivalent to the assignment
-<code>_env.x = val</code>,
-which in turn is equivalent to
-
-<pre>
-     settable_event(_env, "x", val)
-</pre><p>
-where <code>_env</code> is the environment of the running function.
-(The <code>_env</code> variable is not defined in Lua.
-We use it here only for explanatory purposes.)
-
-
-
-
-
-<h3>2.4.4 - <a name="2.4.4">Control Structures</a></h3><p>
-The control structures
-<b>if</b>, <b>while</b>, and <b>repeat</b> have the usual meaning and
-familiar syntax:
-
-
-
-
-<pre>
-	stat ::= <b>while</b> exp <b>do</b> block <b>end</b>
-	stat ::= <b>repeat</b> block <b>until</b> exp
-	stat ::= <b>if</b> exp <b>then</b> block {<b>elseif</b> exp <b>then</b> block} [<b>else</b> block] <b>end</b>
-</pre><p>
-Lua also has a <b>for</b> statement, in two flavors (see <a href="#2.4.5">&sect;2.4.5</a>).
-
-
-<p>
-The condition expression of a
-control structure can return any value.
-Both <b>false</b> and <b>nil</b> are considered false.
-All values different from <b>nil</b> and <b>false</b> are considered true
-(in particular, the number 0 and the empty string are also true).
-
-
-<p>
-In the <b>repeat</b>&ndash;<b>until</b> loop,
-the inner block does not end at the <b>until</b> keyword,
-but only after the condition.
-So, the condition can refer to local variables
-declared inside the loop block.
-
-
-<p>
-The <b>return</b> statement is used to return values
-from a function or a chunk (which is just a function).
-
-Functions and chunks can return more than one value,
-and so the syntax for the <b>return</b> statement is
-
-<pre>
-	stat ::= <b>return</b> [explist]
-</pre>
-
-<p>
-The <b>break</b> statement is used to terminate the execution of a
-<b>while</b>, <b>repeat</b>, or <b>for</b> loop,
-skipping to the next statement after the loop:
-
-
-<pre>
-	stat ::= <b>break</b>
-</pre><p>
-A <b>break</b> ends the innermost enclosing loop.
-
-
-<p>
-The <b>return</b> and <b>break</b>
-statements can only be written as the <em>last</em> statement of a block.
-If it is really necessary to <b>return</b> or <b>break</b> in the
-middle of a block,
-then an explicit inner block can be used,
-as in the idioms
-<code>do return end</code> and <code>do break end</code>,
-because now <b>return</b> and <b>break</b> are the last statements in
-their (inner) blocks.
-
-
-
-
-
-<h3>2.4.5 - <a name="2.4.5">For Statement</a></h3>
-
-<p>
-
-The <b>for</b> statement has two forms:
-one numeric and one generic.
-
-
-<p>
-The numeric <b>for</b> loop repeats a block of code while a
-control variable runs through an arithmetic progression.
-It has the following syntax:
-
-<pre>
-	stat ::= <b>for</b> Name `<b>=</b>&acute; exp `<b>,</b>&acute; exp [`<b>,</b>&acute; exp] <b>do</b> block <b>end</b>
-</pre><p>
-The <em>block</em> is repeated for <em>name</em> starting at the value of
-the first <em>exp</em>, until it passes the second <em>exp</em> by steps of the
-third <em>exp</em>.
-More precisely, a <b>for</b> statement like
-
-<pre>
-     for v = <em>e1</em>, <em>e2</em>, <em>e3</em> do <em>block</em> end
-</pre><p>
-is equivalent to the code:
-
-<pre>
-     do
-       local <em>var</em>, <em>limit</em>, <em>step</em> = tonumber(<em>e1</em>), tonumber(<em>e2</em>), tonumber(<em>e3</em>)
-       if not (<em>var</em> and <em>limit</em> and <em>step</em>) then error() end
-       while (<em>step</em> &gt; 0 and <em>var</em> &lt;= <em>limit</em>) or (<em>step</em> &lt;= 0 and <em>var</em> &gt;= <em>limit</em>) do
-         local v = <em>var</em>
-         <em>block</em>
-         <em>var</em> = <em>var</em> + <em>step</em>
-       end
-     end
-</pre><p>
-Note the following:
-
-<ul>
-
-<li>
-All three control expressions are evaluated only once,
-before the loop starts.
-They must all result in numbers.
-</li>
-
-<li>
-<code><em>var</em></code>, <code><em>limit</em></code>, and <code><em>step</em></code> are invisible variables.
-The names shown here are for explanatory purposes only.
-</li>
-
-<li>
-If the third expression (the step) is absent,
-then a step of&nbsp;1 is used.
-</li>
-
-<li>
-You can use <b>break</b> to exit a <b>for</b> loop.
-</li>
-
-<li>
-The loop variable <code>v</code> is local to the loop;
-you cannot use its value after the <b>for</b> ends or is broken.
-If you need this value,
-assign it to another variable before breaking or exiting the loop.
-</li>
-
-</ul>
-
-<p>
-The generic <b>for</b> statement works over functions,
-called <em>iterators</em>.
-On each iteration, the iterator function is called to produce a new value,
-stopping when this new value is <b>nil</b>.
-The generic <b>for</b> loop has the following syntax:
-
-<pre>
-	stat ::= <b>for</b> namelist <b>in</b> explist <b>do</b> block <b>end</b>
-	namelist ::= Name {`<b>,</b>&acute; Name}
-</pre><p>
-A <b>for</b> statement like
-
-<pre>
-     for <em>var_1</em>, &middot;&middot;&middot;, <em>var_n</em> in <em>explist</em> do <em>block</em> end
-</pre><p>
-is equivalent to the code:
-
-<pre>
-     do
-       local <em>f</em>, <em>s</em>, <em>var</em> = <em>explist</em>
-       while true do
-         local <em>var_1</em>, &middot;&middot;&middot;, <em>var_n</em> = <em>f</em>(<em>s</em>, <em>var</em>)
-         <em>var</em> = <em>var_1</em>
-         if <em>var</em> == nil then break end
-         <em>block</em>
-       end
-     end
-</pre><p>
-Note the following:
-
-<ul>
-
-<li>
-<code><em>explist</em></code> is evaluated only once.
-Its results are an <em>iterator</em> function,
-a <em>state</em>,
-and an initial value for the first <em>iterator variable</em>.
-</li>
-
-<li>
-<code><em>f</em></code>, <code><em>s</em></code>, and <code><em>var</em></code> are invisible variables.
-The names are here for explanatory purposes only.
-</li>
-
-<li>
-You can use <b>break</b> to exit a <b>for</b> loop.
-</li>
-
-<li>
-The loop variables <code><em>var_i</em></code> are local to the loop;
-you cannot use their values after the <b>for</b> ends.
-If you need these values,
-then assign them to other variables before breaking or exiting the loop.
-</li>
-
-</ul>
-
-
-
-
-<h3>2.4.6 - <a name="2.4.6">Function Calls as Statements</a></h3><p>
-To allow possible side-effects,
-function calls can be executed as statements:
-
-<pre>
-	stat ::= functioncall
-</pre><p>
-In this case, all returned values are thrown away.
-Function calls are explained in <a href="#2.5.8">&sect;2.5.8</a>.
-
-
-
-
-
-<h3>2.4.7 - <a name="2.4.7">Local Declarations</a></h3><p>
-Local variables can be declared anywhere inside a block.
-The declaration can include an initial assignment:
-
-<pre>
-	stat ::= <b>local</b> namelist [`<b>=</b>&acute; explist]
-</pre><p>
-If present, an initial assignment has the same semantics
-of a multiple assignment (see <a href="#2.4.3">&sect;2.4.3</a>).
-Otherwise, all variables are initialized with <b>nil</b>.
-
-
-<p>
-A chunk is also a block (see <a href="#2.4.1">&sect;2.4.1</a>),
-and so local variables can be declared in a chunk outside any explicit block.
-The scope of such local variables extends until the end of the chunk.

-<h2>2.5 - <a name="2.5">Expressions</a></h2>
-
-<p>
-The basic expressions in Lua are the following:
-
-<pre>
-	exp ::= prefixexp
-	exp ::= <b>nil</b> | <b>false</b> | <b>true</b>
-	exp ::= Number
-	exp ::= String
-	exp ::= function
-	exp ::= tableconstructor
-	exp ::= `<b>...</b>&acute;
-	exp ::= exp binop exp
-	exp ::= unop exp
-	prefixexp ::= var | functioncall | `<b>(</b>&acute; exp `<b>)</b>&acute;
-</pre>
-
-<p>
-Numbers and literal strings are explained in <a href="#2.1">&sect;2.1</a>;
-variables are explained in <a href="#2.3">&sect;2.3</a>;
-function definitions are explained in <a href="#2.5.9">&sect;2.5.9</a>;
-function calls are explained in <a href="#2.5.8">&sect;2.5.8</a>;
-table constructors are explained in <a href="#2.5.7">&sect;2.5.7</a>.
-Vararg expressions,
-denoted by three dots ('<code>...</code>'), can only be used when
-directly inside a vararg function;
-they are explained in <a href="#2.5.9">&sect;2.5.9</a>.
-
-
-<p>
-Binary operators comprise arithmetic operators (see <a href="#2.5.1">&sect;2.5.1</a>),
-relational operators (see <a href="#2.5.2">&sect;2.5.2</a>), logical operators (see <a href="#2.5.3">&sect;2.5.3</a>),
-and the concatenation operator (see <a href="#2.5.4">&sect;2.5.4</a>).
-Unary operators comprise the unary minus (see <a href="#2.5.1">&sect;2.5.1</a>),
-the unary <b>not</b> (see <a href="#2.5.3">&sect;2.5.3</a>),
-and the unary <em>length operator</em> (see <a href="#2.5.5">&sect;2.5.5</a>).
-
-
-<p>
-Both function calls and vararg expressions can result in multiple values.
-If an expression is used as a statement
-(only possible for function calls (see <a href="#2.4.6">&sect;2.4.6</a>)),
-then its return list is adjusted to zero elements,
-thus discarding all returned values.
-If an expression is used as the last (or the only) element
-of a list of expressions,
-then no adjustment is made
-(unless the call is enclosed in parentheses).
-In all other contexts,
-Lua adjusts the result list to one element,
-discarding all values except the first one.
-
-
-<p>
-Here are some examples:
-
-<pre>
-     f()                -- adjusted to 0 results
-     g(f(), x)          -- f() is adjusted to 1 result
-     g(x, f())          -- g gets x plus all results from f()
-     a,b,c = f(), x     -- f() is adjusted to 1 result (c gets nil)
-     a,b = ...          -- a gets the first vararg parameter, b gets
-                        -- the second (both a and b can get nil if there
-                        -- is no corresponding vararg parameter)
-     
-     a,b,c = x, f()     -- f() is adjusted to 2 results
-     a,b,c = f()        -- f() is adjusted to 3 results
-     return f()         -- returns all results from f()
-     return ...         -- returns all received vararg parameters
-     return x,y,f()     -- returns x, y, and all results from f()
-     {f()}              -- creates a list with all results from f()
-     {...}              -- creates a list with all vararg parameters
-     {f(), nil}         -- f() is adjusted to 1 result
-</pre>
-
-<p>
-Any expression enclosed in parentheses always results in only one value.
-Thus,
-<code>(f(x,y,z))</code> is always a single value,
-even if <code>f</code> returns several values.
-(The value of <code>(f(x,y,z))</code> is the first value returned by <code>f</code>
-or <b>nil</b> if <code>f</code> does not return any values.)
-
-
-
-<h3>2.5.1 - <a name="2.5.1">Arithmetic Operators</a></h3><p>
-Lua supports the usual arithmetic operators:
-the binary <code>+</code> (addition),
-<code>-</code> (subtraction), <code>*</code> (multiplication),
-<code>/</code> (division), <code>%</code> (modulo), and <code>^</code> (exponentiation);
-and unary <code>-</code> (negation).
-If the operands are numbers, or strings that can be converted to
-numbers (see <a href="#2.2.1">&sect;2.2.1</a>),
-then all operations have the usual meaning.
-Exponentiation works for any exponent.
-For instance, <code>x^(-0.5)</code> computes the inverse of the square root of <code>x</code>.
-Modulo is defined as
-
-<pre>
-     a % b == a - math.floor(a/b)*b
-</pre><p>
-That is, it is the remainder of a division that rounds
-the quotient towards minus infinity.
-
-
-
-
-
-<h3>2.5.2 - <a name="2.5.2">Relational Operators</a></h3><p>
-The relational operators in Lua are
-
-<pre>
-     ==    ~=    &lt;     &gt;     &lt;=    &gt;=
-</pre><p>
-These operators always result in <b>false</b> or <b>true</b>.
-
-
-<p>
-Equality (<code>==</code>) first compares the type of its operands.
-If the types are different, then the result is <b>false</b>.
-Otherwise, the values of the operands are compared.
-Numbers and strings are compared in the usual way.
-Objects (tables, userdata, threads, and functions)
-are compared by <em>reference</em>:
-two objects are considered equal only if they are the <em>same</em> object.
-Every time you create a new object
-(a table, userdata, thread, or function),
-this new object is different from any previously existing object.
-
-
-<p>
-You can change the way that Lua compares tables and userdata 
-by using the "eq" metamethod (see <a href="#2.8">&sect;2.8</a>).
-
-
-<p>
-The conversion rules of <a href="#2.2.1">&sect;2.2.1</a>
-<em>do not</em> apply to equality comparisons.
-Thus, <code>"0"==0</code> evaluates to <b>false</b>,
-and <code>t[0]</code> and <code>t["0"]</code> denote different
-entries in a table.
-
-
-<p>
-The operator <code>~=</code> is exactly the negation of equality (<code>==</code>).
-
-
-<p>
-The order operators work as follows.
-If both arguments are numbers, then they are compared as such.
-Otherwise, if both arguments are strings,
-then their values are compared according to the current locale.
-Otherwise, Lua tries to call the "lt" or the "le"
-metamethod (see <a href="#2.8">&sect;2.8</a>).
-A comparison <code>a &gt; b</code> is translated to <code>b &lt; a</code>
-and <code>a &gt;= b</code> is translated to <code>b &lt;= a</code>.
-
-
-
-
-
-<h3>2.5.3 - <a name="2.5.3">Logical Operators</a></h3><p>
-The logical operators in Lua are
-<b>and</b>, <b>or</b>, and <b>not</b>.
-Like the control structures (see <a href="#2.4.4">&sect;2.4.4</a>),
-all logical operators consider both <b>false</b> and <b>nil</b> as false
-and anything else as true.
-
-
-<p>
-The negation operator <b>not</b> always returns <b>false</b> or <b>true</b>.
-The conjunction operator <b>and</b> returns its first argument
-if this value is <b>false</b> or <b>nil</b>;
-otherwise, <b>and</b> returns its second argument.
-The disjunction operator <b>or</b> returns its first argument
-if this value is different from <b>nil</b> and <b>false</b>;
-otherwise, <b>or</b> returns its second argument.
-Both <b>and</b> and <b>or</b> use short-cut evaluation;
-that is,
-the second operand is evaluated only if necessary.
-Here are some examples:
-
-<pre>
-     10 or 20            --&gt; 10
-     10 or error()       --&gt; 10
-     nil or "a"          --&gt; "a"
-     nil and 10          --&gt; nil
-     false and error()   --&gt; false
-     false and nil       --&gt; false
-     false or nil        --&gt; nil
-     10 and 20           --&gt; 20
-</pre><p>
-(In this manual,
-<code>--&gt;</code> indicates the result of the preceding expression.)
-
-
-
-
-
-<h3>2.5.4 - <a name="2.5.4">Concatenation</a></h3><p>
-The string concatenation operator in Lua is
-denoted by two dots ('<code>..</code>').
-If both operands are strings or numbers, then they are converted to
-strings according to the rules mentioned in <a href="#2.2.1">&sect;2.2.1</a>.
-Otherwise, the "concat" metamethod is called (see <a href="#2.8">&sect;2.8</a>).
-
-
-
-
-
-<h3>2.5.5 - <a name="2.5.5">The Length Operator</a></h3>
-
-<p>
-The length operator is denoted by the unary operator <code>#</code>.
-The length of a string is its number of bytes
-(that is, the usual meaning of string length when each
-character is one byte).
-
-
-<p>
-The length of a table <code>t</code> is defined to be any
-integer index <code>n</code>
-such that <code>t[n]</code> is not <b>nil</b> and <code>t[n+1]</code> is <b>nil</b>;
-moreover, if <code>t[1]</code> is <b>nil</b>, <code>n</code> can be zero.
-For a regular array, with non-nil values from 1 to a given <code>n</code>,
-its length is exactly that <code>n</code>,
-the index of its last value.
-If the array has "holes"
-(that is, <b>nil</b> values between other non-nil values),
-then <code>#t</code> can be any of the indices that
-directly precedes a <b>nil</b> value
-(that is, it may consider any such <b>nil</b> value as the end of
-the array). 
-
-
-
-
-
-<h3>2.5.6 - <a name="2.5.6">Precedence</a></h3><p>
-Operator precedence in Lua follows the table below,
-from lower to higher priority:
-
-<pre>
-     or
-     and
-     &lt;     &gt;     &lt;=    &gt;=    ~=    ==
-     ..
-     +     -
-     *     /     %
-     not   #     - (unary)
-     ^
-</pre><p>
-As usual,
-you can use parentheses to change the precedences of an expression.
-The concatenation ('<code>..</code>') and exponentiation ('<code>^</code>')
-operators are right associative.
-All other binary operators are left associative.
-
-
-
-
-
-<h3>2.5.7 - <a name="2.5.7">Table Constructors</a></h3><p>
-Table constructors are expressions that create tables.
-Every time a constructor is evaluated, a new table is created.
-A constructor can be used to create an empty table
-or to create a table and initialize some of its fields.
-The general syntax for constructors is
-
-<pre>
-	tableconstructor ::= `<b>{</b>&acute; [fieldlist] `<b>}</b>&acute;
-	fieldlist ::= field {fieldsep field} [fieldsep]
-	field ::= `<b>[</b>&acute; exp `<b>]</b>&acute; `<b>=</b>&acute; exp | Name `<b>=</b>&acute; exp | exp
-	fieldsep ::= `<b>,</b>&acute; | `<b>;</b>&acute;
-</pre>
-
-<p>
-Each field of the form <code>[exp1] = exp2</code> adds to the new table an entry
-with key <code>exp1</code> and value <code>exp2</code>.
-A field of the form <code>name = exp</code> is equivalent to
-<code>["name"] = exp</code>.
-Finally, fields of the form <code>exp</code> are equivalent to
-<code>[i] = exp</code>, where <code>i</code> are consecutive numerical integers,
-starting with 1.
-Fields in the other formats do not affect this counting.
-For example,
-
-<pre>
-     a = { [f(1)] = g; "x", "y"; x = 1, f(x), [30] = 23; 45 }
-</pre><p>
-is equivalent to
-
-<pre>
-     do
-       local t = {}
-       t[f(1)] = g
-       t[1] = "x"         -- 1st exp
-       t[2] = "y"         -- 2nd exp
-       t.x = 1            -- t["x"] = 1
-       t[3] = f(x)        -- 3rd exp
-       t[30] = 23
-       t[4] = 45          -- 4th exp
-       a = t
-     end
-</pre>
-
-<p>
-If the last field in the list has the form <code>exp</code>
-and the expression is a function call or a vararg expression,
-then all values returned by this expression enter the list consecutively
-(see <a href="#2.5.8">&sect;2.5.8</a>).
-To avoid this,
-enclose the function call or the vararg expression
-in parentheses (see <a href="#2.5">&sect;2.5</a>).
-
-
-<p>
-The field list can have an optional trailing separator,
-as a convenience for machine-generated code.
-
-
-
-
-
-<h3>2.5.8 - <a name="2.5.8">Function Calls</a></h3><p>
-A function call in Lua has the following syntax:
-
-<pre>
-	functioncall ::= prefixexp args
-</pre><p>
-In a function call,
-first prefixexp and args are evaluated.
-If the value of prefixexp has type <em>function</em>,
-then this function is called
-with the given arguments.
-Otherwise, the prefixexp "call" metamethod is called,
-having as first parameter the value of prefixexp,
-followed by the original call arguments
-(see <a href="#2.8">&sect;2.8</a>).
-
-
-<p>
-The form
-
-<pre>
-	functioncall ::= prefixexp `<b>:</b>&acute; Name args
-</pre><p>
-can be used to call "methods".
-A call <code>v:name(<em>args</em>)</code>
-is syntactic sugar for <code>v.name(v,<em>args</em>)</code>,
-except that <code>v</code> is evaluated only once.
-
-
-<p>
-Arguments have the following syntax:
-
-<pre>
-	args ::= `<b>(</b>&acute; [explist] `<b>)</b>&acute;
-	args ::= tableconstructor
-	args ::= String
-</pre><p>
-All argument expressions are evaluated before the call.
-A call of the form <code>f{<em>fields</em>}</code> is
-syntactic sugar for <code>f({<em>fields</em>})</code>;
-that is, the argument list is a single new table.
-A call of the form <code>f'<em>string</em>'</code>
-(or <code>f"<em>string</em>"</code> or <code>f[[<em>string</em>]]</code>)
-is syntactic sugar for <code>f('<em>string</em>')</code>;
-that is, the argument list is a single literal string.
-
-
-<p>
-As an exception to the free-format syntax of Lua,
-you cannot put a line break before the '<code>(</code>' in a function call.
-This restriction avoids some ambiguities in the language.
-If you write
-
-<pre>
-     a = f
-     (g).x(a)
-</pre><p>
-Lua would see that as a single statement, <code>a = f(g).x(a)</code>.
-So, if you want two statements, you must add a semi-colon between them.
-If you actually want to call <code>f</code>,
-you must remove the line break before <code>(g)</code>.
-
-
-<p>
-A call of the form <code>return</code> <em>functioncall</em> is called
-a <em>tail call</em>.
-Lua implements <em>proper tail calls</em>
-(or <em>proper tail recursion</em>):
-in a tail call,
-the called function reuses the stack entry of the calling function.
-Therefore, there is no limit on the number of nested tail calls that
-a program can execute.
-However, a tail call erases any debug information about the
-calling function.
-Note that a tail call only happens with a particular syntax,
-where the <b>return</b> has one single function call as argument;
-this syntax makes the calling function return exactly
-the returns of the called function.
-So, none of the following examples are tail calls:
-
-<pre>
-     return (f(x))        -- results adjusted to 1
-     return 2 * f(x)
-     return x, f(x)       -- additional results
-     f(x); return         -- results discarded
-     return x or f(x)     -- results adjusted to 1
-</pre>
-
-
-
-
-<h3>2.5.9 - <a name="2.5.9">Function Definitions</a></h3>
-
-<p>
-The syntax for function definition is
-
-<pre>
-	function ::= <b>function</b> funcbody
-	funcbody ::= `<b>(</b>&acute; [parlist] `<b>)</b>&acute; block <b>end</b>
-</pre>
-
-<p>
-The following syntactic sugar simplifies function definitions:
-
-<pre>
-	stat ::= <b>function</b> funcname funcbody
-	stat ::= <b>local</b> <b>function</b> Name funcbody
-	funcname ::= Name {`<b>.</b>&acute; Name} [`<b>:</b>&acute; Name]
-</pre><p>
-The statement
-
-<pre>
-     function f () <em>body</em> end
-</pre><p>
-translates to
-
-<pre>
-     f = function () <em>body</em> end
-</pre><p>
-The statement
-
-<pre>
-     function t.a.b.c.f () <em>body</em> end
-</pre><p>
-translates to
-
-<pre>
-     t.a.b.c.f = function () <em>body</em> end
-</pre><p>
-The statement
-
-<pre>
-     local function f () <em>body</em> end
-</pre><p>
-translates to
-
-<pre>
-     local f; f = function () <em>body</em> end
-</pre><p>
-<em>not</em> to
-
-<pre>
-     local f = function () <em>body</em> end
-</pre><p>
-(This only makes a difference when the body of the function
-contains references to <code>f</code>.)
-
-
-<p>
-A function definition is an executable expression,
-whose value has type <em>function</em>.
-When Lua pre-compiles a chunk,
-all its function bodies are pre-compiled too.
-Then, whenever Lua executes the function definition,
-the function is <em>instantiated</em> (or <em>closed</em>).
-This function instance (or <em>closure</em>)
-is the final value of the expression.
-Different instances of the same function
-can refer to different  external local variables
-and can have different environment tables.
-
-
-<p>
-Parameters act as local variables that are
-initialized with the argument values:
-
-<pre>
-	parlist ::= namelist [`<b>,</b>&acute; `<b>...</b>&acute;] | `<b>...</b>&acute;
-</pre><p>
-When a function is called,
-the list of arguments is adjusted to
-the length of the list of parameters,
-unless the function is a variadic or <em>vararg function</em>,
-which is
-indicated by three dots ('<code>...</code>') at the end of its parameter list.
-A vararg function does not adjust its argument list;
-instead, it collects all extra arguments and supplies them
-to the function through a <em>vararg expression</em>,
-which is also written as three dots.
-The value of this expression is a list of all actual extra arguments,
-similar to a function with multiple results.
-If a vararg expression is used inside another expression
-or in the middle of a list of expressions,
-then its return list is adjusted to one element.
-If the expression is used as the last element of a list of expressions,
-then no adjustment is made
-(unless that last expression is enclosed in parentheses).
-
-
-<p>
-As an example, consider the following definitions:
-
-<pre>
-     function f(a, b) end
-     function g(a, b, ...) end
-     function r() return 1,2,3 end
-</pre><p>
-Then, we have the following mapping from arguments to parameters and
-to the vararg expression:
-
-<pre>
-     CALL            PARAMETERS
-     
-     f(3)             a=3, b=nil
-     f(3, 4)          a=3, b=4
-     f(3, 4, 5)       a=3, b=4
-     f(r(), 10)       a=1, b=10
-     f(r())           a=1, b=2
-     
-     g(3)             a=3, b=nil, ... --&gt;  (nothing)
-     g(3, 4)          a=3, b=4,   ... --&gt;  (nothing)
-     g(3, 4, 5, 8)    a=3, b=4,   ... --&gt;  5  8
-     g(5, r())        a=5, b=1,   ... --&gt;  2  3
-</pre>
-
-<p>
-Results are returned using the <b>return</b> statement (see <a href="#2.4.4">&sect;2.4.4</a>).
-If control reaches the end of a function
-without encountering a <b>return</b> statement,
-then the function returns with no results.
-
-
-<p>
-The <em>colon</em> syntax
-is used for defining <em>methods</em>,
-that is, functions that have an implicit extra parameter <code>self</code>.
-Thus, the statement
-
-<pre>
-     function t.a.b.c:f (<em>params</em>) <em>body</em> end
-</pre><p>
-is syntactic sugar for
-
-<pre>
-     t.a.b.c.f = function (self, <em>params</em>) <em>body</em> end
-</pre>
-
-
-

-
-
-<h2>2.6 - <a name="2.6">Visibility Rules</a></h2>
-
-<p>
-
-Lua is a lexically scoped language.
-The scope of variables begins at the first statement <em>after</em>
-their declaration and lasts until the end of the innermost block that
-includes the declaration.
-Consider the following example:
-
-<pre>
-     x = 10                -- global variable
-     do                    -- new block
-       local x = x         -- new 'x', with value 10
-       print(x)            --&gt; 10
-       x = x+1
-       do                  -- another block
-         local x = x+1     -- another 'x'
-         print(x)          --&gt; 12
-       end
-       print(x)            --&gt; 11
-     end
-     print(x)              --&gt; 10  (the global one)
-</pre>
-
-<p>
-Notice that, in a declaration like <code>local x = x</code>,
-the new <code>x</code> being declared is not in scope yet,
-and so the second <code>x</code> refers to the outside variable.
-
-
-<p>
-Because of the lexical scoping rules,
-local variables can be freely accessed by functions
-defined inside their scope.
-A local variable used by an inner function is called
-an <em>upvalue</em>, or <em>external local variable</em>,
-inside the inner function.
-
-
-<p>
-Notice that each execution of a <b>local</b> statement
-defines new local variables.
-Consider the following example:
-
-<pre>
-     a = {}
-     local x = 20
-     for i=1,10 do
-       local y = 0
-       a[i] = function () y=y+1; return x+y end
-     end
-</pre><p>
-The loop creates ten closures
-(that is, ten instances of the anonymous function).
-Each of these closures uses a different <code>y</code> variable,
-while all of them share the same <code>x</code>.
-
-
-
-
-
-<h2>2.7 - <a name="2.7">Error Handling</a></h2>
-
-<p>
-Because Lua is an embedded extension language,
-all Lua actions start from C&nbsp;code in the host program
-calling a function from the Lua library (see <a href="#lua_pcall"><code>lua_pcall</code></a>).
-Whenever an error occurs during Lua compilation or execution,
-control returns to C,
-which can take appropriate measures
-(such as printing an error message).
-
-
-<p>
-Lua code can explicitly generate an error by calling the
-<a href="#pdf-error"><code>error</code></a> function.
-If you need to catch errors in Lua,
-you can use the <a href="#pdf-pcall"><code>pcall</code></a> function.

-<h2>2.8 - <a name="2.8">Metatables</a></h2>
-
-<p>
-Every value in Lua can have a <em>metatable</em>.
-This <em>metatable</em> is an ordinary Lua table
-that defines the behavior of the original value
-under certain special operations.
-You can change several aspects of the behavior
-of operations over a value by setting specific fields in its metatable.
-For instance, when a non-numeric value is the operand of an addition,
-Lua checks for a function in the field <code>"__add"</code> in its metatable.
-If it finds one,
-Lua calls this function to perform the addition.
-
-
-<p>
-We call the keys in a metatable <em>events</em>
-and the values <em>metamethods</em>.
-In the previous example, the event is <code>"add"</code> 
-and the metamethod is the function that performs the addition.
-
-
-<p>
-You can query the metatable of any value
-through the <a href="#pdf-getmetatable"><code>getmetatable</code></a> function.
-
-
-<p>
-You can replace the metatable of tables
-through the <a href="#pdf-setmetatable"><code>setmetatable</code></a>
-function.
-You cannot change the metatable of other types from Lua
-(except by using the debug library);
-you must use the C&nbsp;API for that.
-
-
-<p>
-Tables and full userdata have individual metatables
-(although multiple tables and userdata can share their metatables).
-Values of all other types share one single metatable per type;
-that is, there is one single metatable for all numbers,
-one for all strings, etc.
-
-
-<p>
-A metatable controls how an object behaves in arithmetic operations,
-order comparisons, concatenation, length operation, and indexing.
-A metatable also can define a function to be called when a userdata
-is garbage collected.
-For each of these operations Lua associates a specific key
-called an <em>event</em>.
-When Lua performs one of these operations over a value,
-it checks whether this value has a metatable with the corresponding event.
-If so, the value associated with that key (the metamethod)
-controls how Lua will perform the operation.
-
-
-<p>
-Metatables control the operations listed next.
-Each operation is identified by its corresponding name.
-The key for each operation is a string with its name prefixed by
-two underscores, '<code>__</code>';
-for instance, the key for operation "add" is the
-string <code>"__add"</code>.
-The semantics of these operations is better explained by a Lua function
-describing how the interpreter executes the operation.
-
-
-<p>
-The code shown here in Lua is only illustrative;
-the real behavior is hard coded in the interpreter
-and it is much more efficient than this simulation.
-All functions used in these descriptions
-(<a href="#pdf-rawget"><code>rawget</code></a>, <a href="#pdf-tonumber"><code>tonumber</code></a>, etc.)
-are described in <a href="#5.1">&sect;5.1</a>.
-In particular, to retrieve the metamethod of a given object,
-we use the expression
-
-<pre>
-     metatable(obj)[event]
-</pre><p>
-This should be read as
-
-<pre>
-     rawget(getmetatable(obj) or {}, event)
-</pre><p>
-
-That is, the access to a metamethod does not invoke other metamethods,
-and the access to objects with no metatables does not fail
-(it simply results in <b>nil</b>).

-<h2>2.9 - <a name="2.9">Environments</a></h2>
-
-<p>
-Besides metatables,
-objects of types thread, function, and userdata
-have another table associated with them,
-called their <em>environment</em>.
-Like metatables, environments are regular tables and
-multiple objects can share the same environment.
-
-
-<p>
-Threads are created sharing the environment of the creating thread.
-Userdata and C&nbsp;functions are created sharing the environment
-of the creating C&nbsp;function.
-Non-nested Lua functions
-(created by <a href="#pdf-loadfile"><code>loadfile</code></a>, <a href="#pdf-loadstring"><code>loadstring</code></a> or <a href="#pdf-load"><code>load</code></a>)
-are created sharing the environment of the creating thread.
-Nested Lua functions are created sharing the environment of
-the creating Lua function.
-
-
-<p>
-Environments associated with userdata have no meaning for Lua.
-It is only a convenience feature for programmers to associate a table to
-a userdata.
-
-
-<p>
-Environments associated with threads are called
-<em>global environments</em>.
-They are used as the default environment for threads and
-non-nested Lua functions created by the thread
-and can be directly accessed by C&nbsp;code (see <a href="#3.3">&sect;3.3</a>).
-
-
-<p>
-The environment associated with a C&nbsp;function can be directly
-accessed by C&nbsp;code (see <a href="#3.3">&sect;3.3</a>).
-It is used as the default environment for other C&nbsp;functions
-and userdata created by the function.
-
-
-<p>
-Environments associated with Lua functions are used to resolve
-all accesses to global variables within the function (see <a href="#2.3">&sect;2.3</a>).
-They are used as the default environment for nested Lua functions
-created by the function.
-
-
-<p>
-You can change the environment of a Lua function or the
-running thread by calling <a href="#pdf-setfenv"><code>setfenv</code></a>.
-You can get the environment of a Lua function or the running thread
-by calling <a href="#pdf-getfenv"><code>getfenv</code></a>.
-To manipulate the environment of other objects
-(userdata, C&nbsp;functions, other threads) you must
-use the C&nbsp;API.

-
-
-<h2>2.10 - <a name="2.10">Garbage Collection</a></h2>
-
-<p>
-Lua performs automatic memory management.
-This means that
-you have to worry neither about allocating memory for new objects
-nor about freeing it when the objects are no longer needed.
-Lua manages memory automatically by running
-a <em>garbage collector</em> from time to time
-to collect all <em>dead objects</em>
-(that is, objects that are no longer accessible from Lua).
-All memory used by Lua is subject to automatic management:
-tables, userdata, functions, threads, strings, etc.
-
-
-<p>
-Lua implements an incremental mark-and-sweep collector.
-It uses two numbers to control its garbage-collection cycles:
-the <em>garbage-collector pause</em> and
-the <em>garbage-collector step multiplier</em>.
-Both use percentage points as units
-(so that a value of 100 means an internal value of 1).
-
-
-<p>
-The garbage-collector pause
-controls how long the collector waits before starting a new cycle.
-Larger values make the collector less aggressive.
-Values smaller than 100 mean the collector will not wait to
-start a new cycle.
-A value of 200 means that the collector waits for the total memory in use
-to double before starting a new cycle.
-
-
-<p>
-The step multiplier
-controls the relative speed of the collector relative to
-memory allocation.
-Larger values make the collector more aggressive but also increase
-the size of each incremental step.
-Values smaller than 100 make the collector too slow and
-can result in the collector never finishing a cycle.
-The default, 200, means that the collector runs at "twice"
-the speed of memory allocation.
-
-
-<p>
-You can change these numbers by calling <a href="#lua_gc"><code>lua_gc</code></a> in C
-or <a href="#pdf-collectgarbage"><code>collectgarbage</code></a> in Lua.
-With these functions you can also control 
-the collector directly (e.g., stop and restart it).
-
-
-
-<h3>2.10.1 - <a name="2.10.1">Garbage-Collection Metamethods</a></h3>
-
-<p>
-Using the C&nbsp;API,
-you can set garbage-collector metamethods for userdata (see <a href="#2.8">&sect;2.8</a>).
-These metamethods are also called <em>finalizers</em>.
-Finalizers allow you to coordinate Lua's garbage collection
-with external resource management
-(such as closing files, network or database connections,
-or freeing your own memory).
-
-
-<p>
-Garbage userdata with a field <code>__gc</code> in their metatables are not
-collected immediately by the garbage collector.
-Instead, Lua puts them in a list.
-After the collection,
-Lua does the equivalent of the following function
-for each userdata in that list:
-
-<pre>
-     function gc_event (udata)
-       local h = metatable(udata).__gc
-       if h then
-         h(udata)
-       end
-     end
-</pre>
-
-<p>
-At the end of each garbage-collection cycle,
-the finalizers for userdata are called in <em>reverse</em>
-order of their creation,
-among those collected in that cycle.
-That is, the first finalizer to be called is the one associated
-with the userdata created last in the program.
-The userdata itself is freed only in the next garbage-collection cycle.
-
-
-
-
-
-<h3>2.10.2 - <a name="2.10.2">Weak Tables</a></h3>
-
-<p>
-A <em>weak table</em> is a table whose elements are
-<em>weak references</em>.
-A weak reference is ignored by the garbage collector.
-In other words,
-if the only references to an object are weak references,
-then the garbage collector will collect this object.
-
-
-<p>
-A weak table can have weak keys, weak values, or both.
-A table with weak keys allows the collection of its keys,
-but prevents the collection of its values.
-A table with both weak keys and weak values allows the collection of
-both keys and values.
-In any case, if either the key or the value is collected,
-the whole pair is removed from the table.
-The weakness of a table is controlled by the
-<code>__mode</code> field of its metatable.
-If the <code>__mode</code> field is a string containing the character&nbsp;'<code>k</code>',
-the keys in the table are weak.
-If <code>__mode</code> contains '<code>v</code>',
-the values in the table are weak.
-
-
-<p>
-After you use a table as a metatable,
-you should not change the value of its <code>__mode</code> field.
-Otherwise, the weak behavior of the tables controlled by this
-metatable is undefined.
-

-
-<h2>2.11 - <a name="2.11">Coroutines</a></h2>
-
-<p>
-Lua supports coroutines,
-also called <em>collaborative multithreading</em>.
-A coroutine in Lua represents an independent thread of execution.
-Unlike threads in multithread systems, however,
-a coroutine only suspends its execution by explicitly calling
-a yield function.
-
-
-<p>
-You create a coroutine with a call to <a href="#pdf-coroutine.create"><code>coroutine.create</code></a>.
-Its sole argument is a function
-that is the main function of the coroutine.
-The <code>create</code> function only creates a new coroutine and
-returns a handle to it (an object of type <em>thread</em>);
-it does not start the coroutine execution.
-
-
-<p>
-When you first call <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>,
-passing as its first argument
-a thread returned by <a href="#pdf-coroutine.create"><code>coroutine.create</code></a>,
-the coroutine starts its execution,
-at the first line of its main function.
-Extra arguments passed to <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> are passed on
-to the coroutine main function.
-After the coroutine starts running,
-it runs until it terminates or <em>yields</em>.
-
-
-<p>
-A coroutine can terminate its execution in two ways:
-normally, when its main function returns
-(explicitly or implicitly, after the last instruction);
-and abnormally, if there is an unprotected error.
-In the first case, <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> returns <b>true</b>,
-plus any values returned by the coroutine main function.
-In case of errors, <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> returns <b>false</b>
-plus an error message.
-
-
-<p>
-A coroutine yields by calling <a href="#pdf-coroutine.yield"><code>coroutine.yield</code></a>.
-When a coroutine yields,
-the corresponding <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> returns immediately,
-even if the yield happens inside nested function calls
-(that is, not in the main function,
-but in a function directly or indirectly called by the main function).
-In the case of a yield, <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> also returns <b>true</b>,
-plus any values passed to <a href="#pdf-coroutine.yield"><code>coroutine.yield</code></a>.
-The next time you resume the same coroutine,
-it continues its execution from the point where it yielded,
-with the call to <a href="#pdf-coroutine.yield"><code>coroutine.yield</code></a> returning any extra
-arguments passed to <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>.
-
-
-<p>
-Like <a href="#pdf-coroutine.create"><code>coroutine.create</code></a>,
-the <a href="#pdf-coroutine.wrap"><code>coroutine.wrap</code></a> function also creates a coroutine,
-but instead of returning the coroutine itself,
-it returns a function that, when called, resumes the coroutine.
-Any arguments passed to this function
-go as extra arguments to <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>.
-<a href="#pdf-coroutine.wrap"><code>coroutine.wrap</code></a> returns all the values returned by <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>,
-except the first one (the boolean error code).
-Unlike <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>,
-<a href="#pdf-coroutine.wrap"><code>coroutine.wrap</code></a> does not catch errors;
-any error is propagated to the caller.
-
-
-<p>
-As an example,
-consider the following code:
-
-<pre>
-     function foo (a)
-       print("foo", a)
-       return coroutine.yield(2*a)
-     end
-     
-     co = coroutine.create(function (a,b)
-           print("co-body", a, b)
-           local r = foo(a+1)
-           print("co-body", r)
-           local r, s = coroutine.yield(a+b, a-b)
-           print("co-body", r, s)
-           return b, "end"
-     end)
-            
-     print("main", coroutine.resume(co, 1, 10))
-     print("main", coroutine.resume(co, "r"))
-     print("main", coroutine.resume(co, "x", "y"))
-     print("main", coroutine.resume(co, "x", "y"))
-</pre><p>
-When you run it, it produces the following output:
-
-<pre>
-     co-body 1       10
-     foo     2
-     
-     main    true    4
-     co-body r
-     main    true    11      -9
-     co-body x       y
-     main    true    10      end
-     main    false   cannot resume dead coroutine

-<h1>3 - <a name="3">The Application Program Interface</a></h1>
-
-<p>
-
-This section describes the C&nbsp;API for Lua, that is,
-the set of C&nbsp;functions available to the host program to communicate
-with Lua.
-All API functions and related types and constants
-are declared in the header file <a name="pdf-lua.h"><code>lua.h</code></a>.
-
-
-<p>
-Even when we use the term "function",
-any facility in the API may be provided as a macro instead.
-All such macros use each of their arguments exactly once
-(except for the first argument, which is always a Lua state),
-and so do not generate any hidden side-effects.
-
-
-<p>
-As in most C&nbsp;libraries,
-the Lua API functions do not check their arguments for validity or consistency.
-However, you can change this behavior by compiling Lua
-with a proper definition for the macro <a name="pdf-luai_apicheck"><code>luai_apicheck</code></a>,
-in file <code>luaconf.h</code>.
-
-
-
-<h2>3.1 - <a name="3.1">The Stack</a></h2>
-
-<p>
-Lua uses a <em>virtual stack</em> to pass values to and from C.
-Each element in this stack represents a Lua value
-(<b>nil</b>, number, string, etc.).
-
-
-<p>
-Whenever Lua calls C, the called function gets a new stack,
-which is independent of previous stacks and of stacks of
-C&nbsp;functions that are still active.
-This stack initially contains any arguments to the C&nbsp;function
-and it is where the C&nbsp;function pushes its results
-to be returned to the caller (see <a href="#lua_CFunction"><code>lua_CFunction</code></a>).
-
-
-<p>
-For convenience,
-most query operations in the API do not follow a strict stack discipline.
-Instead, they can refer to any element in the stack
-by using an <em>index</em>:
-A positive index represents an <em>absolute</em> stack position
-(starting at&nbsp;1);
-a negative index represents an <em>offset</em> relative to the top of the stack.
-More specifically, if the stack has <em>n</em> elements,
-then index&nbsp;1 represents the first element
-(that is, the element that was pushed onto the stack first)
-and
-index&nbsp;<em>n</em> represents the last element;
-index&nbsp;-1 also represents the last element
-(that is, the element at the&nbsp;top)
-and index <em>-n</em> represents the first element.
-We say that an index is <em>valid</em>
-if it lies between&nbsp;1 and the stack top
-(that is, if <code>1 &le; abs(index) &le; top</code>).
- 
-
-
-
-
-
-<h2>3.2 - <a name="3.2">Stack Size</a></h2>
-
-<p>
-When you interact with Lua API,
-you are responsible for ensuring consistency.
-In particular,
-<em>you are responsible for controlling stack overflow</em>.
-You can use the function <a href="#lua_checkstack"><code>lua_checkstack</code></a>
-to grow the stack size.
-
-
-<p>
-Whenever Lua calls C,
-it ensures that at least <a name="pdf-LUA_MINSTACK"><code>LUA_MINSTACK</code></a> stack positions are available.
-<code>LUA_MINSTACK</code> is defined as 20,
-so that usually you do not have to worry about stack space
-unless your code has loops pushing elements onto the stack.
-
-
-<p>
-Most query functions accept as indices any value inside the
-available stack space, that is, indices up to the maximum stack size
-you have set through <a href="#lua_checkstack"><code>lua_checkstack</code></a>.
-Such indices are called <em>acceptable indices</em>.
-More formally, we define an <em>acceptable index</em>
-as follows:
-
-<pre>
-     (index &lt; 0 &amp;&amp; abs(index) &lt;= top) ||
-     (index &gt; 0 &amp;&amp; index &lt;= stackspace)
-</pre><p>
-Note that 0 is never an acceptable index.
-
-
-
-
-
-<h2>3.3 - <a name="3.3">Pseudo-Indices</a></h2>
-
-<p>
-Unless otherwise noted,
-any function that accepts valid indices can also be called with
-<em>pseudo-indices</em>,
-which represent some Lua values that are accessible to C&nbsp;code
-but which are not in the stack.
-Pseudo-indices are used to access the thread environment,
-the function environment,
-the registry,
-and the upvalues of a C&nbsp;function (see <a href="#3.4">&sect;3.4</a>).
-
-
-<p>
-The thread environment (where global variables live) is
-always at pseudo-index <a name="pdf-LUA_GLOBALSINDEX"><code>LUA_GLOBALSINDEX</code></a>.
-The environment of the running C&nbsp;function is always
-at pseudo-index <a name="pdf-LUA_ENVIRONINDEX"><code>LUA_ENVIRONINDEX</code></a>.
-
-
-<p>
-To access and change the value of global variables,
-you can use regular table operations over an environment table.
-For instance, to access the value of a global variable, do
-
-<pre>
-     lua_getfield(L, LUA_GLOBALSINDEX, varname);
-</pre>
-
-
-
-
-<h2>3.4 - <a name="3.4">C Closures</a></h2>
-
-<p>
-When a C&nbsp;function is created,
-it is possible to associate some values with it,
-thus creating a <em>C&nbsp;closure</em>;
-these values are called <em>upvalues</em> and are
-accessible to the function whenever it is called
-(see <a href="#lua_pushcclosure"><code>lua_pushcclosure</code></a>).
-
-
-<p>
-Whenever a C&nbsp;function is called,
-its upvalues are located at specific pseudo-indices.
-These pseudo-indices are produced by the macro
-<a name="lua_upvalueindex"><code>lua_upvalueindex</code></a>.
-The first value associated with a function is at position
-<code>lua_upvalueindex(1)</code>, and so on.
-Any access to <code>lua_upvalueindex(<em>n</em>)</code>,
-where <em>n</em> is greater than the number of upvalues of the
-current function (but not greater than 256),
-produces an acceptable (but invalid) index.
-
-
-
-
-
-<h2>3.5 - <a name="3.5">Registry</a></h2>
-
-<p>
-Lua provides a <em>registry</em>,
-a pre-defined table that can be used by any C&nbsp;code to
-store whatever Lua value it needs to store.
-This table is always located at pseudo-index
-<a name="pdf-LUA_REGISTRYINDEX"><code>LUA_REGISTRYINDEX</code></a>.
-Any C&nbsp;library can store data into this table,
-but it should take care to choose keys different from those used
-by other libraries, to avoid collisions.
-Typically, you should use as key a string containing your library name
-or a light userdata with the address of a C&nbsp;object in your code.
-
-
-<p>
-The integer keys in the registry are used by the reference mechanism,
-implemented by the auxiliary library,
-and therefore should not be used for other purposes.
-
-
-
-
-
-<h2>3.6 - <a name="3.6">Error Handling in C</a></h2>
-
-<p>
-Internally, Lua uses the C <code>longjmp</code> facility to handle errors.
-(You can also choose to use exceptions if you use C++;
-see file <code>luaconf.h</code>.)
-When Lua faces any error
-(such as memory allocation errors, type errors, syntax errors,
-and runtime errors)
-it <em>raises</em> an error;
-that is, it does a long jump.
-A <em>protected environment</em> uses <code>setjmp</code>
-to set a recover point;
-any error jumps to the most recent active recover point.
-
-
-<p>
-Most functions in the API can throw an error,
-for instance due to a memory allocation error.
-The documentation for each function indicates whether
-it can throw errors.
-
-
-<p>
-Inside a C&nbsp;function you can throw an error by calling <a href="#lua_error"><code>lua_error</code></a>.
-
-
-
-
-
-<h2>3.7 - <a name="3.7">Functions and Types</a></h2>
-
-<p>
-Here we list all functions and types from the C&nbsp;API in
-alphabetical order.
-Each function has an indicator like this:
-<span class="apii">[-o, +p, <em>x</em>]</span>
-
-
-<p>
-The first field, <code>o</code>,
-is how many elements the function pops from the stack.
-The second field, <code>p</code>,
-is how many elements the function pushes onto the stack.
-(Any function always pushes its results after popping its arguments.)
-A field in the form <code>x|y</code> means the function can push (or pop)
-<code>x</code> or <code>y</code> elements,
-depending on the situation;
-an interrogation mark '<code>?</code>' means that
-we cannot know how many elements the function pops/pushes
-by looking only at its arguments
-(e.g., they may depend on what is on the stack).
-The third field, <code>x</code>,
-tells whether the function may throw errors:
-'<code>-</code>' means the function never throws any error;
-'<code>m</code>' means the function may throw an error
-only due to not enough memory;
-'<code>e</code>' means the function may throw other kinds of errors;
-'<code>v</code>' means the function may throw an error on purpose.

-<pre>typedef void * (*lua_Alloc) (void *ud,
-                             void *ptr,
-                             size_t osize,
-                             size_t nsize);</pre>
-
-<p>
-The type of the memory-allocation function used by Lua states.
-The allocator function must provide a
-functionality similar to <code>realloc</code>,
-but not exactly the same.
-Its arguments are
-<code>ud</code>, an opaque pointer passed to <a href="#lua_newstate"><code>lua_newstate</code></a>;
-<code>ptr</code>, a pointer to the block being allocated/reallocated/freed;
-<code>osize</code>, the original size of the block;
-<code>nsize</code>, the new size of the block.
-<code>ptr</code> is <code>NULL</code> if and only if <code>osize</code> is zero.
-When <code>nsize</code> is zero, the allocator must return <code>NULL</code>;
-if <code>osize</code> is not zero,
-it should free the block pointed to by <code>ptr</code>.
-When <code>nsize</code> is not zero, the allocator returns <code>NULL</code>
-if and only if it cannot fill the request.
-When <code>nsize</code> is not zero and <code>osize</code> is zero,
-the allocator should behave like <code>malloc</code>.
-When <code>nsize</code> and <code>osize</code> are not zero,
-the allocator behaves like <code>realloc</code>.
-Lua assumes that the allocator never fails when
-<code>osize &gt;= nsize</code>.
-
-
-<p>
-Here is a simple implementation for the allocator function.
-It is used in the auxiliary library by <a href="#luaL_newstate"><code>luaL_newstate</code></a>.
-
-<pre>
-     static void *l_alloc (void *ud, void *ptr, size_t osize,
-                                                size_t nsize) {
-       (void)ud;  (void)osize;  /* not used */
-       if (nsize == 0) {
-         free(ptr);
-         return NULL;
-       }
-       else
-         return realloc(ptr, nsize);
-     }
-</pre><p>
-This code assumes
-that <code>free(NULL)</code> has no effect and that
-<code>realloc(NULL, size)</code> is equivalent to <code>malloc(size)</code>.
-ANSI&nbsp;C ensures both behaviors.

-<span class="apii">[-0, +0, <em>-</em>]</span>
-<pre>lua_CFunction lua_atpanic (lua_State *L, lua_CFunction panicf);</pre>
-
-<p>
-Sets a new panic function and returns the old one.
-
-
-<p>
-If an error happens outside any protected environment,
-Lua calls a <em>panic function</em>
-and then calls <code>exit(EXIT_FAILURE)</code>,
-thus exiting the host application.
-Your panic function can avoid this exit by
-never returning (e.g., doing a long jump).
-
-
-<p>
-The panic function can access the error message at the top of the stack.
-
-
-
-
-
-<hr><h3><a name="lua_call"><code>lua_call</code></a></h3><p>
-<span class="apii">[-(nargs + 1), +nresults, <em>e</em>]</span>
-<pre>void lua_call (lua_State *L, int nargs, int nresults);</pre>
-
-<p>
-Calls a function.
-
-
-<p>
-To call a function you must use the following protocol:
-first, the function to be called is pushed onto the stack;
-then, the arguments to the function are pushed
-in direct order;
-that is, the first argument is pushed first.
-Finally you call <a href="#lua_call"><code>lua_call</code></a>;
-<code>nargs</code> is the number of arguments that you pushed onto the stack.
-All arguments and the function value are popped from the stack
-when the function is called.
-The function results are pushed onto the stack when the function returns.
-The number of results is adjusted to <code>nresults</code>,
-unless <code>nresults</code> is <a name="pdf-LUA_MULTRET"><code>LUA_MULTRET</code></a>.
-In this case, <em>all</em> results from the function are pushed.
-Lua takes care that the returned values fit into the stack space.
-The function results are pushed onto the stack in direct order
-(the first result is pushed first),
-so that after the call the last result is on the top of the stack.
-
-
-<p>
-Any error inside the called function is propagated upwards
-(with a <code>longjmp</code>).
-
-
-<p>
-The following example shows how the host program can do the
-equivalent to this Lua code:
-
-<pre>
-     a = f("how", t.x, 14)
-</pre><p>
-Here it is in&nbsp;C:
-
-<pre>
-     lua_getfield(L, LUA_GLOBALSINDEX, "f"); /* function to be called */
-     lua_pushstring(L, "how");                        /* 1st argument */
-     lua_getfield(L, LUA_GLOBALSINDEX, "t");   /* table to be indexed */
-     lua_getfield(L, -1, "x");        /* push result of t.x (2nd arg) */
-     lua_remove(L, -2);                  /* remove 't' from the stack */
-     lua_pushinteger(L, 14);                          /* 3rd argument */
-     lua_call(L, 3, 1);     /* call 'f' with 3 arguments and 1 result */
-     lua_setfield(L, LUA_GLOBALSINDEX, "a");        /* set global 'a' */
-</pre><p>
-Note that the code above is "balanced":
-at its end, the stack is back to its original configuration.
-This is considered good programming practice.
-

-<hr><h3><a name="lua_CFunction"><code>lua_CFunction</code></a></h3>
-<pre>typedef int (*lua_CFunction) (lua_State *L);</pre>
-
-<p>
-Type for C&nbsp;functions.
-
-
-<p>
-In order to communicate properly with Lua,
-a C&nbsp;function must use the following protocol,
-which defines the way parameters and results are passed:
-a C&nbsp;function receives its arguments from Lua in its stack
-in direct order (the first argument is pushed first).
-So, when the function starts,
-<code>lua_gettop(L)</code> returns the number of arguments received by the function.
-The first argument (if any) is at index 1
-and its last argument is at index <code>lua_gettop(L)</code>.
-To return values to Lua, a C&nbsp;function just pushes them onto the stack,
-in direct order (the first result is pushed first),
-and returns the number of results.
-Any other value in the stack below the results will be properly
-discarded by Lua.
-Like a Lua function, a C&nbsp;function called by Lua can also return
-many results.
-
-
-<p>
-As an example, the following function receives a variable number
-of numerical arguments and returns their average and sum:
-
-<pre>
-     static int foo (lua_State *L) {
-       int n = lua_gettop(L);    /* number of arguments */
-       lua_Number sum = 0;

-       for (i = 1; i &lt;= n; i++) {
-         if (!lua_isnumber(L, i)) {
-           lua_pushstring(L, "incorrect argument");
-           lua_error(L);
-         }
-         sum += lua_tonumber(L, i);
-       }
-       lua_pushnumber(L, sum/n);        /* first result */
-       lua_pushnumber(L, sum);         /* second result */

-A structure used to carry different pieces of

-of this structure, for later use.
-To fill the other fields of <a href="#lua_Debug"><code>lua_Debug</code></a> with useful information,
-call <a href="#lua_getinfo"><code>lua_getinfo</code></a>.
-
-
-<p>
-The fields of <a href="#lua_Debug"><code>lua_Debug</code></a> have the following meaning:
-
-<ul>
-
-<li><b><code>source</code>:</b>
-If the function was defined in a string,
-then <code>source</code> is that string.
-If the function was defined in a file,
-then <code>source</code> starts with a '<code>@</code>' followed by the file name.
-</li>
-
-<li><b><code>short_src</code>:</b>
-a "printable" version of <code>source</code>, to be used in error messages.
-</li>
-
-<li><b><code>linedefined</code>:</b>
-the line number where the definition of the function starts.
-</li>
-
-<li><b><code>lastlinedefined</code>:</b>
-the line number where the definition of the function ends.
-</li>
-
-<li><b><code>what</code>:</b>
-the string <code>"Lua"</code> if the function is a Lua function,
-<code>"C"</code> if it is a C&nbsp;function,
-<code>"main"</code> if it is the main part of a chunk,
-and <code>"tail"</code> if it was a function that did a tail call.
-In the latter case,
-Lua has no other information about the function.
-</li>
-
-<li><b><code>currentline</code>:</b>
-the current line where the given function is executing.
-When no line information is available,
-<code>currentline</code> is set to -1.
-</li>
-
-<li><b><code>name</code>:</b>
-a reasonable name for the given function.
-Because functions in Lua are first-class values,
-they do not have a fixed name:
-some functions can be the value of multiple global variables,
-while others can be stored only in a table field.
-The <code>lua_getinfo</code> function checks how the function was
-called to find a suitable name.
-If it cannot find a name,
-then <code>name</code> is set to <code>NULL</code>.
-</li>
-
-<li><b><code>namewhat</code>:</b>
-explains the <code>name</code> field.
-The value of <code>namewhat</code> can be
-<code>"global"</code>, <code>"local"</code>, <code>"method"</code>,
-<code>"field"</code>, <code>"upvalue"</code>, or <code>""</code> (the empty string),
-according to how the function was called.
-(Lua uses the empty string when no other option seems to apply.)
-</li>
-
-<li><b><code>nups</code>:</b>
-the number of upvalues of the function.

-Gets information about a closure's upvalue.
-(For Lua functions,
-upvalues are the external local variables that the function uses,
-and that are consequently included in its closure.)
-<a href="#lua_getupvalue"><code>lua_getupvalue</code></a> gets the index <code>n</code> of an upvalue,
-pushes the upvalue's value onto the stack,

-<code>funcindex</code> points to the closure in the stack.
-(Upvalues have no particular order,
-as they are active through the whole function.
-So, they are numbered in an arbitrary order.)
-
-
-<p>
-Returns <code>NULL</code> (and pushes nothing)

-Type for debugging hook functions.
-
-
-<p>
-Whenever a hook is called, its <code>ar</code> argument has its field
-<code>event</code> set to the specific event that triggered the hook.
-Lua identifies these events with the following constants:
-<a name="pdf-LUA_HOOKCALL"><code>LUA_HOOKCALL</code></a>, <a name="pdf-LUA_HOOKRET"><code>LUA_HOOKRET</code></a>,
-<a name="pdf-LUA_HOOKTAILRET"><code>LUA_HOOKTAILRET</code></a>, <a name="pdf-LUA_HOOKLINE"><code>LUA_HOOKLINE</code></a>,
-and <a name="pdf-LUA_HOOKCOUNT"><code>LUA_HOOKCOUNT</code></a>.
-Moreover, for line events, the field <code>currentline</code> is also set.
-To get the value of any other field in <code>ar</code>,
-the hook must call <a href="#lua_getinfo"><code>lua_getinfo</code></a>.
-For return events, <code>event</code> can be <code>LUA_HOOKRET</code>,
-the normal value, or <code>LUA_HOOKTAILRET</code>.
-In the latter case, Lua is simulating a return from
-a function that did a tail call;
-in this case, it is useless to call <a href="#lua_getinfo"><code>lua_getinfo</code></a>.
-
-
-<p>
-While Lua is running a hook, it disables other calls to hooks.
-Therefore, if a hook calls back Lua to execute a function or a chunk,
-this execution occurs without any calls to hooks.

-<a name="pdf-LUA_MASKLINE"><code>LUA_MASKLINE</code></a>,
-and <a name="pdf-LUA_MASKCOUNT"><code>LUA_MASKCOUNT</code></a>.
-The <code>count</code> argument is only meaningful when the mask
-includes <code>LUA_MASKCOUNT</code>.
-For each event, the hook is called as explained below:
-
-<ul>
-
-<li><b>The call hook:</b> is called when the interpreter calls a function.
-The hook is called just after Lua enters the new function,
-before the function gets its arguments.
-</li>
-
-<li><b>The return hook:</b> is called when the interpreter returns from a function.
-The hook is called just before Lua leaves the function.
-You have no access to the values to be returned by the function.
-</li>
-
-<li><b>The line hook:</b> is called when the interpreter is about to
-start the execution of a new line of code,
-or when it jumps back in the code (even to the same line).
-(This event only happens while Lua is executing a Lua function.)
-</li>
-
-<li><b>The count hook:</b> is called after the interpreter executes every
-<code>count</code> instructions.
-(This event only happens while Lua is executing a Lua function.)

-<h1>4 - <a name="4">The Auxiliary Library</a></h1>
-
-<p>
-
-The <em>auxiliary library</em> provides several convenient functions
-to interface C with Lua.
-While the basic API provides the primitive functions for all 
-interactions between C and Lua,
-the auxiliary library provides higher-level functions for some
-common tasks.
-
-
-<p>
-All functions from the auxiliary library
-are defined in header file <code>lauxlib.h</code> and
-have a prefix <code>luaL_</code>.
-
-
-<p>
-All functions in the auxiliary library are built on
-top of the basic API,
-and so they provide nothing that cannot be done with this API.
-
-
-<p>
-Several functions in the auxiliary library are used to
-check C&nbsp;function arguments.
-Their names are always <code>luaL_check*</code> or <code>luaL_opt*</code>.
-All of these functions throw an error if the check is not satisfied.
-Because the error message is formatted for arguments
-(e.g., "<code>bad argument #1</code>"),
-you should not use these functions for other stack values.
-

-<pre>typedef struct luaL_Buffer luaL_Buffer;</pre>
-
-<p>
-Type for a <em>string buffer</em>.
-
-
-<p>
-A string buffer allows C&nbsp;code to build Lua strings piecemeal.
-Its pattern of use is as follows:
-
-<ul>
-
-<li>First you declare a variable <code>b</code> of type <a href="#luaL_Buffer"><code>luaL_Buffer</code></a>.</li>
-
-<li>Then you initialize it with a call <code>luaL_buffinit(L, &amp;b)</code>.</li>
-
-<li>
-Then you add string pieces to the buffer calling any of
-the <code>luaL_add*</code> functions.
-</li>
-
-<li>
-You finish by calling <code>luaL_pushresult(&amp;b)</code>.
-This call leaves the final string on the top of the stack.
-</li>
-
-</ul>
-
-<p>
-During its normal operation,
-a string buffer uses a variable number of stack slots.
-So, while using a buffer, you cannot assume that you know where
-the top of the stack is.
-You can use the stack between successive calls to buffer operations
-as long as that use is balanced;
-that is,
-when you call a buffer operation,
-the stack is at the same level
-it was immediately after the previous buffer operation.
-(The only exception to this rule is <a href="#luaL_addvalue"><code>luaL_addvalue</code></a>.)
-After calling <a href="#luaL_pushresult"><code>luaL_pushresult</code></a> the stack is back to its
-level when the buffer was initialized,
-plus the final string on its top.

-<h1>5 - <a name="5">Standard Libraries</a></h1>
-
-<p>
-The standard Lua libraries provide useful functions
-that are implemented directly through the C&nbsp;API.
-Some of these functions provide essential services to the language
-(e.g., <a href="#pdf-type"><code>type</code></a> and <a href="#pdf-getmetatable"><code>getmetatable</code></a>);
-others provide access to "outside" services (e.g., I/O);
-and others could be implemented in Lua itself,
-but are quite useful or have critical performance requirements that
-deserve an implementation in C (e.g., <a href="#pdf-table.sort"><code>table.sort</code></a>).
-
-
-<p>
-All libraries are implemented through the official C&nbsp;API
-and are provided as separate C&nbsp;modules.
-Currently, Lua has the following standard libraries:
-
-<ul>
-
-<li>basic library, which includes the coroutine sub-library;</li>
-
-<li>package library;</li>
-
-<li>string manipulation;</li>
-
-<li>table manipulation;</li>
-
-<li>mathematical functions (sin, log, etc.);</li>
-
-<li>input and output;</li>
-
-<li>operating system facilities;</li>
-
-<li>debug facilities.</li>
-
-</ul><p>
-Except for the basic and package libraries,
-each library provides all its functions as fields of a global table
-or as methods of its objects.
-
-
-<p>
-To have access to these libraries,
-the C&nbsp;host program should call the <a href="#luaL_openlibs"><code>luaL_openlibs</code></a> function,
-which opens all standard libraries.
-Alternatively,
-it can open them individually by calling
-<a name="pdf-luaopen_base"><code>luaopen_base</code></a> (for the basic library),
-<a name="pdf-luaopen_package"><code>luaopen_package</code></a> (for the package library),
-<a name="pdf-luaopen_string"><code>luaopen_string</code></a> (for the string library),
-<a name="pdf-luaopen_table"><code>luaopen_table</code></a> (for the table library),
-<a name="pdf-luaopen_math"><code>luaopen_math</code></a> (for the mathematical library),
-<a name="pdf-luaopen_io"><code>luaopen_io</code></a> (for the I/O library),
-<a name="pdf-luaopen_os"><code>luaopen_os</code></a> (for the Operating System library),
-and <a name="pdf-luaopen_debug"><code>luaopen_debug</code></a> (for the debug library).
-These functions are declared in <a name="pdf-lualib.h"><code>lualib.h</code></a>
-and should not be called directly:
-you must call them like any other Lua C&nbsp;function,
-e.g., by using <a href="#lua_call"><code>lua_call</code></a>.
-
-
-
-<h2>5.1 - <a name="5.1">Basic Functions</a></h2>
-
-<p>
-The basic library provides some core functions to Lua.
-If you do not include this library in your application,
-you should check carefully whether you need to provide 
-implementations for some of its facilities.
-
-
-<p>
-<hr><h3><a name="pdf-assert"><code>assert (v [, message])</code></a></h3>
-Issues an  error when
-the value of its argument <code>v</code> is false (i.e., <b>nil</b> or <b>false</b>);
-otherwise, returns all its arguments.
-<code>message</code> is an error message;
-when absent, it defaults to "assertion failed!"
-
-
-
-
-<p>
-<hr><h3><a name="pdf-collectgarbage"><code>collectgarbage ([opt [, arg]])</code></a></h3>
-
-
-<p>
-This function is a generic interface to the garbage collector.
-It performs different functions according to its first argument, <code>opt</code>:
-
-<ul>
-
-<li><b>"collect":</b>
-performs a full garbage-collection cycle.
-This is the default option.
-</li>
-
-<li><b>"stop":</b>
-stops the garbage collector.
-</li>
-
-<li><b>"restart":</b>
-restarts the garbage collector.
-</li>
-
-<li><b>"count":</b>
-returns the total memory in use by Lua (in Kbytes).
-</li>
-
-<li><b>"step":</b>
-performs a garbage-collection step.
-The step "size" is controlled by <code>arg</code>
-(larger values mean more steps) in a non-specified way.
-If you want to control the step size
-you must experimentally tune the value of <code>arg</code>.
-Returns <b>true</b> if the step finished a collection cycle.
-</li>
-
-<li><b>"setpause":</b>
-sets <code>arg</code> as the new value for the <em>pause</em> of
-the collector (see <a href="#2.10">&sect;2.10</a>).
-Returns the previous value for <em>pause</em>.
-</li>
-
-<li><b>"setstepmul":</b>
-sets <code>arg</code> as the new value for the <em>step multiplier</em> of
-the collector (see <a href="#2.10">&sect;2.10</a>).
-Returns the previous value for <em>step</em>.
-</li>
-
-</ul>

-<p>
-<hr><h3><a name="pdf-dofile"><code>dofile ([filename])</code></a></h3>
-Opens the named file and executes its contents as a Lua chunk.
-When called without arguments,
-<code>dofile</code> executes the contents of the standard input (<code>stdin</code>).
-Returns all values returned by the chunk.
-In case of errors, <code>dofile</code> propagates the error
-to its caller (that is, <code>dofile</code> does not run in protected mode).
-
-
-
-
-<p>
-<hr><h3><a name="pdf-error"><code>error (message [, level])</code></a></h3>
-Terminates the last protected function called
-and returns <code>message</code> as the error message.
-Function <code>error</code> never returns.
-
-
-<p>
-Usually, <code>error</code> adds some information about the error position
-at the beginning of the message.
-The <code>level</code> argument specifies how to get the error position.
-With level&nbsp;1 (the default), the error position is where the
-<code>error</code> function was called.
-Level&nbsp;2 points the error to where the function
-that called <code>error</code> was called; and so on.
-Passing a level&nbsp;0 avoids the addition of error position information
-to the message.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-_G"><code>_G</code></a></h3>
-A global variable (not a function) that
-holds the global environment (that is, <code>_G._G = _G</code>).
-Lua itself does not use this variable;
-changing its value does not affect any environment,
-nor vice-versa.
-(Use <a href="#pdf-setfenv"><code>setfenv</code></a> to change environments.)
-
-
-
-
-<p>
-<hr><h3><a name="pdf-getfenv"><code>getfenv ([f])</code></a></h3>
-Returns the current environment in use by the function.
-<code>f</code> can be a Lua function or a number
-that specifies the function at that stack level:
-Level&nbsp;1 is the function calling <code>getfenv</code>.
-If the given function is not a Lua function,
-or if <code>f</code> is 0,
-<code>getfenv</code> returns the global environment.
-The default for <code>f</code> is 1.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-getmetatable"><code>getmetatable (object)</code></a></h3>
-
-
-<p>

-if the object's metatable has a <code>"__metatable"</code> field,
-returns the associated value.
-Otherwise, returns the metatable of the given object.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-ipairs"><code>ipairs (t)</code></a></h3>
-
-
-<p>
-Returns three values: an iterator function, the table <code>t</code>, and 0,
-so that the construction
-
-<pre>
-     for i,v in ipairs(t) do <em>body</em> end
-</pre><p>
-will iterate over the pairs (<code>1,t[1]</code>), (<code>2,t[2]</code>), &middot;&middot;&middot;,
-up to the first integer key absent from the table.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-load"><code>load (func [, chunkname])</code></a></h3>
-
-
-<p>
-Loads a chunk using function <code>func</code> to get its pieces.
-Each call to <code>func</code> must return a string that concatenates
-with previous results.
-A return of an empty string, <b>nil</b>, or no value signals the end of the chunk.
-
-
-<p>
-If there are no errors, 
-returns the compiled chunk as a function;
-otherwise, returns <b>nil</b> plus the error message.
-The environment of the returned function is the global environment.
-
-
-<p>
-<code>chunkname</code> is used as the chunk name for error messages
-and debug information.
-When absent,
-it defaults to "<code>=(load)</code>".
-
-
-
-
-<p>
-<hr><h3><a name="pdf-loadfile"><code>loadfile ([filename])</code></a></h3>
-
-
-<p>
-Similar to <a href="#pdf-load"><code>load</code></a>,

-
-
-
-
-<p>
-<hr><h3><a name="pdf-loadstring"><code>loadstring (string [, chunkname])</code></a></h3>
-
-
-<p>
-Similar to <a href="#pdf-load"><code>load</code></a>,
-but gets the chunk from the given string.
-
-
-<p>
-To load and run a given string, use the idiom
-
-<pre>
-     assert(loadstring(s))()
-</pre>
-
-<p>
-When absent,
-<code>chunkname</code> defaults to the given string.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-next"><code>next (table [, index])</code></a></h3>
-
-
-<p>
-Allows a program to traverse all fields of a table.
-Its first argument is a table and its second argument
-is an index in this table.
-<code>next</code> returns the next index of the table
-and its associated value.
-When called with <b>nil</b> as its second argument,
-<code>next</code> returns an initial index
-and its associated value.
-When called with the last index,
-or with <b>nil</b> in an empty table,
-<code>next</code> returns <b>nil</b>.
-If the second argument is absent, then it is interpreted as <b>nil</b>.
-In particular,
-you can use <code>next(t)</code> to check whether a table is empty.
-
-
-<p>
-The order in which the indices are enumerated is not specified,
-<em>even for numeric indices</em>.
-(To traverse a table in numeric order,
-use a numerical <b>for</b> or the <a href="#pdf-ipairs"><code>ipairs</code></a> function.)
-
-
-<p>
-The behavior of <code>next</code> is <em>undefined</em> if,
-during the traversal,
-you assign any value to a non-existent field in the table.
-You may however modify existing fields.
-In particular, you may clear existing fields.

-<hr><h3><a name="pdf-pcall"><code>pcall (f, arg1, &middot;&middot;&middot;)</code></a></h3>
-
-
-<p>
-Calls function <code>f</code> with
-the given arguments in <em>protected mode</em>.
-This means that any error inside&nbsp;<code>f</code> is not propagated;
-instead, <code>pcall</code> catches the error
-and returns a status code.
-Its first result is the status code (a boolean),
-which is true if the call succeeds without errors.
-In such case, <code>pcall</code> also returns all results from the call,
-after this first result.
-In case of any error, <code>pcall</code> returns <b>false</b> plus the error message.
-
-
-
-
-<p>

-Receives an argument of any type and
-converts it to a string in a reasonable format.
-For complete control of how numbers are converted,
-use <a href="#pdf-string.format"><code>string.format</code></a>.
-
-
-<p>
-If the metatable of <code>e</code> has a <code>"__tostring"</code> field,
-then <code>tostring</code> calls the corresponding value
-with <code>e</code> as argument,

-
-<h2>5.3 - <a name="5.3">Modules</a></h2>
-
-<p>
-The package library provides basic
-facilities for loading and building modules in Lua.
-It exports two of its functions directly in the global environment:
-<a href="#pdf-require"><code>require</code></a> and <a href="#pdf-module"><code>module</code></a>.
-Everything else is exported in a table <a name="pdf-package"><code>package</code></a>.
-
-
-<p>
-<hr><h3><a name="pdf-module"><code>module (name [, &middot;&middot;&middot;])</code></a></h3>
-
-
-<p>
-Creates a module.
-If there is a table in <code>package.loaded[name]</code>,
-this table is the module.
-Otherwise, if there is a global table <code>t</code> with the given name,
-this table is the module.
-Otherwise creates a new table <code>t</code> and
-sets it as the value of the global <code>name</code> and
-the value of <code>package.loaded[name]</code>.
-This function also initializes <code>t._NAME</code> with the given name,
-<code>t._M</code> with the module (<code>t</code> itself),
-and <code>t._PACKAGE</code> with the package name
-(the full module name minus last component; see below).
-Finally, <code>module</code> sets <code>t</code> as the new environment
-of the current function and the new value of <code>package.loaded[name]</code>,
-so that <a href="#pdf-require"><code>require</code></a> returns <code>t</code>.
-
-
-<p>
-If <code>name</code> is a compound name
-(that is, one with components separated by dots),
-<code>module</code> creates (or reuses, if they already exist)
-tables for each component.
-For instance, if <code>name</code> is <code>a.b.c</code>,
-then <code>module</code> stores the module table in field <code>c</code> of
-field <code>b</code> of global <code>a</code>.
-
-
-<p>
-This function can receive optional <em>options</em> after
-the module name,
-where each option is a function to be applied over the module.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-require"><code>require (modname)</code></a></h3>
-
-
-<p>
-Loads the given module.
-The function starts by looking into the <a href="#pdf-package.loaded"><code>package.loaded</code></a> table
-to determine whether <code>modname</code> is already loaded.
-If it is, then <code>require</code> returns the value stored
-at <code>package.loaded[modname]</code>.
-Otherwise, it tries to find a <em>loader</em> for the module.
-
-
-<p>
-To find a loader,
-<code>require</code> is guided by the <a href="#pdf-package.loaders"><code>package.loaders</code></a> array.
-By changing this array,
-we can change how <code>require</code> looks for a module.
-The following explanation is based on the default configuration
-for <a href="#pdf-package.loaders"><code>package.loaders</code></a>.
-
-
-<p>
-First <code>require</code> queries <code>package.preload[modname]</code>.
-If it has a value,
-this value (which should be a function) is the loader.
-Otherwise <code>require</code> searches for a Lua loader using the
-path stored in <a href="#pdf-package.path"><code>package.path</code></a>.
-If that also fails, it searches for a C&nbsp;loader using the
-path stored in <a href="#pdf-package.cpath"><code>package.cpath</code></a>.
-If that also fails,
-it tries an <em>all-in-one</em> loader (see <a href="#pdf-package.loaders"><code>package.loaders</code></a>).
-
-
-<p>
-Once a loader is found,
-<code>require</code> calls the loader with a single argument, <code>modname</code>.
-If the loader returns any value,
-<code>require</code> assigns the returned value to <code>package.loaded[modname]</code>.
-If the loader returns no value and
-has not assigned any value to <code>package.loaded[modname]</code>,
-then <code>require</code> assigns <b>true</b> to this entry.
-In any case, <code>require</code> returns the
-final value of <code>package.loaded[modname]</code>.
-
-
-<p>
-If there is any error loading or running the module,
-or if it cannot find any loader for the module,
-then <code>require</code> signals an error.

-The path used by <a href="#pdf-require"><code>require</code></a> to search for a C&nbsp;loader.
-
-
-<p>
-Lua initializes the C&nbsp;path <a href="#pdf-package.cpath"><code>package.cpath</code></a> in the same way
-it initializes the Lua path <a href="#pdf-package.path"><code>package.path</code></a>,
-using the environment variable <a name="pdf-LUA_CPATH"><code>LUA_CPATH</code></a>
-or a default path defined in <code>luaconf.h</code>.

-<hr><h3><a name="pdf-package.loaded"><code>package.loaded</code></a></h3>
-
-
-<p>
-A table used by <a href="#pdf-require"><code>require</code></a> to control which
-modules are already loaded.
-When you require a module <code>modname</code> and
-<code>package.loaded[modname]</code> is not false,
-<a href="#pdf-require"><code>require</code></a> simply returns the value stored there.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-package.loaders"><code>package.loaders</code></a></h3>
-
-
-<p>
-A table used by <a href="#pdf-require"><code>require</code></a> to control how to load modules.
-
-
-<p>
-Each entry in this table is a <em>searcher function</em>.
-When looking for a module,
-<a href="#pdf-require"><code>require</code></a> calls each of these searchers in ascending order,
-with the module name (the argument given to <a href="#pdf-require"><code>require</code></a>) as its
-sole parameter.
-The function can return another function (the module <em>loader</em>)
-or a string explaining why it did not find that module
-(or <b>nil</b> if it has nothing to say).
-Lua initializes this table with four functions.
-
-
-<p>
-The first searcher simply looks for a loader in the
-<a href="#pdf-package.preload"><code>package.preload</code></a> table.
-
-
-<p>
-The second searcher looks for a loader as a Lua library,
-using the path stored at <a href="#pdf-package.path"><code>package.path</code></a>.
-A path is a sequence of <em>templates</em> separated by semicolons.
-For each template,
-the searcher will change each interrogation
-mark in the template by <code>filename</code>,
-which is the module name with each dot replaced by a
-"directory separator" (such as "<code>/</code>" in Unix);
-then it will try to open the resulting file name.
-So, for instance, if the Lua path is the string
-
-<pre>
-     "./?.lua;./?.lc;/usr/local/?/init.lua"
-</pre><p>
-the search for a Lua file for module <code>foo</code>
-will try to open the files
-<code>./foo.lua</code>, <code>./foo.lc</code>, and
-<code>/usr/local/foo/init.lua</code>, in that order.
-
-
-<p>
-The third searcher looks for a loader as a C&nbsp;library,
-using the path given by the variable <a href="#pdf-package.cpath"><code>package.cpath</code></a>.
-For instance,
-if the C&nbsp;path is the string
-
-<pre>
-     "./?.so;./?.dll;/usr/local/?/init.so"
-</pre><p>
-the searcher for module <code>foo</code>
-will try to open the files <code>./foo.so</code>, <code>./foo.dll</code>,
-and <code>/usr/local/foo/init.so</code>, in that order.
-Once it finds a C&nbsp;library,
-this searcher first uses a dynamic link facility to link the
-application with the library.
-Then it tries to find a C&nbsp;function inside the library to
-be used as the loader.
-The name of this C&nbsp;function is the string "<code>luaopen_</code>"
-concatenated with a copy of the module name where each dot
-is replaced by an underscore.
-Moreover, if the module name has a hyphen,
-its prefix up to (and including) the first hyphen is removed.
-For instance, if the module name is <code>a.v1-b.c</code>,
-the function name will be <code>luaopen_b_c</code>.
-
-
-<p>
-The fourth searcher tries an <em>all-in-one loader</em>.
-It searches the C&nbsp;path for a library for
-the root name of the given module.
-For instance, when requiring <code>a.b.c</code>,
-it will search for a C&nbsp;library for <code>a</code>.
-If found, it looks into it for an open function for
-the submodule;
-in our example, that would be <code>luaopen_a_b_c</code>.
-With this facility, a package can pack several C&nbsp;submodules
-into one single library,
-with each submodule keeping its original open function.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-package.loadlib"><code>package.loadlib (libname, funcname)</code></a></h3>
-
-
-<p>
-Dynamically links the host program with the C&nbsp;library <code>libname</code>.
-Inside this library, looks for a function <code>funcname</code>
-and returns this function as a C&nbsp;function.
-(So, <code>funcname</code> must follow the protocol (see <a href="#lua_CFunction"><code>lua_CFunction</code></a>)).
-
-
-<p>
-This is a low-level function.
-It completely bypasses the package and module system.
-Unlike <a href="#pdf-require"><code>require</code></a>,
-it does not perform any path searching and
-does not automatically adds extensions.
-<code>libname</code> must be the complete file name of the C&nbsp;library,
-including if necessary a path and extension.
-<code>funcname</code> must be the exact name exported by the C&nbsp;library
-(which may depend on the C&nbsp;compiler and linker used).
-
-
-<p>
-This function is not supported by ANSI C.
-As such, it is only available on some platforms
-(Windows, Linux, Mac OS X, Solaris, BSD,
-plus other Unix systems that support the <code>dlfcn</code> standard).

-<p>
-At start-up, Lua initializes this variable with
-the value of the environment variable <a name="pdf-LUA_PATH"><code>LUA_PATH</code></a> or
-with a default path defined in <code>luaconf.h</code>,

-<h2>5.4 - <a name="5.4">String Manipulation</a></h2>
-
-<p>
-This library provides generic functions for string manipulation,
-such as finding and extracting substrings, and pattern matching.
-When indexing a string in Lua, the first character is at position&nbsp;1
-(not at&nbsp;0, as in C).
-Indices are allowed to be negative and are interpreted as indexing backwards,
-from the end of the string.
-Thus, the last character is at position -1, and so on.
-
-
-<p>
-The string library provides all its functions inside the table
-<a name="pdf-string"><code>string</code></a>.
-It also sets a metatable for strings
-where the <code>__index</code> field points to the <code>string</code> table.
-Therefore, you can use the string functions in object-oriented style.
-For instance, <code>string.byte(s, i)</code>
-can be written as <code>s:byte(i)</code>.
-
-
-<p>
-The string library assumes one-byte character encodings.
-
-
-<p>
-<hr><h3><a name="pdf-string.byte"><code>string.byte (s [, i [, j]])</code></a></h3>
-Returns the internal numerical codes of the characters <code>s[i]</code>,
-<code>s[i+1]</code>, &middot;&middot;&middot;, <code>s[j]</code>.
-The default value for <code>i</code> is&nbsp;1;
-the default value for <code>j</code> is&nbsp;<code>i</code>.
-
-
-<p>
-Note that numerical codes are not necessarily portable across platforms.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-string.char"><code>string.char (&middot;&middot;&middot;)</code></a></h3>
-Receives zero or more integers.
-Returns a string with length equal to the number of arguments,
-in which each character has the internal numerical code equal
-to its corresponding argument.
-
-
-<p>
-Note that numerical codes are not necessarily portable across platforms.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-string.dump"><code>string.dump (function)</code></a></h3>
-
-
-<p>
-Returns a string containing a binary representation of the given function,
-so that a later <a href="#pdf-loadstring"><code>loadstring</code></a> on this string returns
-a copy of the function.
-<code>function</code> must be a Lua function without upvalues.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-string.find"><code>string.find (s, pattern [, init [, plain]])</code></a></h3>
-Looks for the first match of
-<code>pattern</code> in the string <code>s</code>.
-If it finds a match, then <code>find</code> returns the indices of&nbsp;<code>s</code>
-where this occurrence starts and ends;
-otherwise, it returns <b>nil</b>.
-A third, optional numerical argument <code>init</code> specifies
-where to start the search;
-its default value is&nbsp;1 and can be negative.
-A value of <b>true</b> as a fourth, optional argument <code>plain</code>
-turns off the pattern matching facilities,
-so the function does a plain "find substring" operation,
-with no characters in <code>pattern</code> being considered "magic".
-Note that if <code>plain</code> is given, then <code>init</code> must be given as well.
-
-
-<p>
-If the pattern has captures,
-then in a successful match
-the captured values are also returned,
-after the two indices.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-string.format"><code>string.format (formatstring, &middot;&middot;&middot;)</code></a></h3>
-Returns a formatted version of its variable number of arguments
-following the description given in its first argument (which must be a string).
-The format string follows the same rules as the <code>printf</code> family of
-standard C&nbsp;functions.
-The only differences are that the options/modifiers
-<code>*</code>, <code>l</code>, <code>L</code>, <code>n</code>, <code>p</code>,
-and <code>h</code> are not supported
-and that there is an extra option, <code>q</code>.
-The <code>q</code> option formats a string in a form suitable to be safely read
-back by the Lua interpreter:
-the string is written between double quotes,
-and all double quotes, newlines, embedded zeros,
-and backslashes in the string
-are correctly escaped when written.
-For instance, the call
-
-<pre>
-     string.format('%q', 'a string with "quotes" and \n new line')
-</pre><p>
-will produce the string:
-
-<pre>
-     "a string with \"quotes\" and \
-      new line"
-</pre>
-
-<p>
-The options <code>c</code>, <code>d</code>, <code>E</code>, <code>e</code>, <code>f</code>,
-<code>g</code>, <code>G</code>, <code>i</code>, <code>o</code>, <code>u</code>, <code>X</code>, and <code>x</code> all
-expect a number as argument,
-whereas <code>q</code> and <code>s</code> expect a string.
-
-
-<p>
-This function does not accept string values
-containing embedded zeros,
-except as arguments to the <code>q</code> option.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-string.gmatch"><code>string.gmatch (s, pattern)</code></a></h3>
-Returns an iterator function that,
-each time it is called,
-returns the next captures from <code>pattern</code> over string <code>s</code>.
-If <code>pattern</code> specifies no captures,
-then the whole match is produced in each call.
-
-
-<p>
-As an example, the following loop
-
-<pre>
-     s = "hello world from Lua"
-     for w in string.gmatch(s, "%a+") do
-       print(w)
-     end
-</pre><p>
-will iterate over all the words from string <code>s</code>,
-printing one per line.
-The next example collects all pairs <code>key=value</code> from the
-given string into a table:
-
-<pre>
-     t = {}
-     s = "from=world, to=Lua"
-     for k, v in string.gmatch(s, "(%w+)=(%w+)") do
-       t[k] = v
-     end
-</pre>
-
-<p>
-For this function, a '<code>^</code>' at the start of a pattern does not
-work as an anchor, as this would prevent the iteration.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-string.gsub"><code>string.gsub (s, pattern, repl [, n])</code></a></h3>
-Returns a copy of <code>s</code>
-in which all (or the first <code>n</code>, if given)
-occurrences of the <code>pattern</code> have been
-replaced by a replacement string specified by <code>repl</code>,
-which can be a string, a table, or a function.
-<code>gsub</code> also returns, as its second value,
-the total number of matches that occurred.
-
-
-<p>
-If <code>repl</code> is a string, then its value is used for replacement.
-The character&nbsp;<code>%</code> works as an escape character:
-any sequence in <code>repl</code> of the form <code>%<em>n</em></code>,
-with <em>n</em> between 1 and 9,
-stands for the value of the <em>n</em>-th captured substring (see below).
-The sequence <code>%0</code> stands for the whole match.
-The sequence <code>%%</code> stands for a single&nbsp;<code>%</code>.
-
-
-<p>
-If <code>repl</code> is a table, then the table is queried for every match,
-using the first capture as the key;
-if the pattern specifies no captures,
-then the whole match is used as the key.
-
-
-<p>
-If <code>repl</code> is a function, then this function is called every time a
-match occurs, with all captured substrings passed as arguments,
-in order;
-if the pattern specifies no captures,
-then the whole match is passed as a sole argument.
-
-
-<p>
-If the value returned by the table query or by the function call
-is a string or a number,
-then it is used as the replacement string;
-otherwise, if it is <b>false</b> or <b>nil</b>,
-then there is no replacement
-(that is, the original match is kept in the string).
-
-
-<p>
-Here are some examples:
-
-<pre>
-     x = string.gsub("hello world", "(%w+)", "%1 %1")
-     --&gt; x="hello hello world world"
-     
-     x = string.gsub("hello world", "%w+", "%0 %0", 1)
-     --&gt; x="hello hello world"
-     
-     x = string.gsub("hello world from Lua", "(%w+)%s*(%w+)", "%2 %1")
-     --&gt; x="world hello Lua from"
-     
-     x = string.gsub("home = $HOME, user = $USER", "%$(%w+)", os.getenv)
-     --&gt; x="home = /home/roberto, user = roberto"
-     
-     x = string.gsub("4+5 = $return 4+5$", "%$(.-)%$", function (s)
-           return loadstring(s)()
-         end)
-     --&gt; x="4+5 = 9"
-     
-     local t = {name="lua", version="5.1"}
-     x = string.gsub("$name-$version.tar.gz", "%$(%w+)", t)
-     --&gt; x="lua-5.1.tar.gz"
-</pre>

-<p>
-<hr><h3><a name="pdf-string.len"><code>string.len (s)</code></a></h3>

-If it finds one, then <code>match</code> returns
-the captures from the pattern;
-otherwise it returns <b>nil</b>.
-If <code>pattern</code> specifies no captures,
-then the whole match is returned.
-A third, optional numerical argument <code>init</code> specifies
-where to start the search;
-its default value is&nbsp;1 and can be negative.

-<p>
-<hr><h3><a name="pdf-string.rep"><code>string.rep (s, n)</code></a></h3>

-
-
-
-
-<p>
-<hr><h3><a name="pdf-string.reverse"><code>string.reverse (s)</code></a></h3>

-<code>i</code> and <code>j</code> can be negative.
-If <code>j</code> is absent, then it is assumed to be equal to -1
-(which is the same as the string length).
-In particular,
-the call <code>string.sub(s,1,j)</code> returns a prefix of <code>s</code>
-with length <code>j</code>,
-and <code>string.sub(s, -i)</code> returns a suffix of <code>s</code>
-with length <code>i</code>.

-
-<h3>5.4.1 - <a name="5.4.1">Patterns</a></h3>
-
-
-<h4>Character Class:</h4><p>
-A <em>character class</em> is used to represent a set of characters.
-The following combinations are allowed in describing a character class:
-
-<ul>
-
-<li><b><em>x</em>:</b>
-(where <em>x</em> is not one of the <em>magic characters</em>
-<code>^$()%.[]*+-?</code>)
-represents the character <em>x</em> itself.
-</li>
-
-<li><b><code>.</code>:</b> (a dot) represents all characters.</li>
-
-<li><b><code>%a</code>:</b> represents all letters.</li>
-
-<li><b><code>%c</code>:</b> represents all control characters.</li>
-
-<li><b><code>%d</code>:</b> represents all digits.</li>
-
-<li><b><code>%l</code>:</b> represents all lowercase letters.</li>
-
-<li><b><code>%p</code>:</b> represents all punctuation characters.</li>
-
-<li><b><code>%s</code>:</b> represents all space characters.</li>
-
-<li><b><code>%u</code>:</b> represents all uppercase letters.</li>
-
-<li><b><code>%w</code>:</b> represents all alphanumeric characters.</li>
-
-<li><b><code>%x</code>:</b> represents all hexadecimal digits.</li>
-
-<li><b><code>%z</code>:</b> represents the character with representation 0.</li>
-
-<li><b><code>%<em>x</em></code>:</b> (where <em>x</em> is any non-alphanumeric character)
-represents the character <em>x</em>.
-This is the standard way to escape the magic characters.
-Any punctuation character (even the non magic)
-can be preceded by a '<code>%</code>'
-when used to represent itself in a pattern.
-</li>
-
-<li><b><code>[<em>set</em>]</code>:</b>
-represents the class which is the union of all
-characters in <em>set</em>.
-A range of characters can be specified by
-separating the end characters of the range with a '<code>-</code>'.
-All classes <code>%</code><em>x</em> described above can also be used as
-components in <em>set</em>.
-All other characters in <em>set</em> represent themselves.
-For example, <code>[%w_]</code> (or <code>[_%w]</code>)
-represents all alphanumeric characters plus the underscore,
-<code>[0-7]</code> represents the octal digits,
-and <code>[0-7%l%-]</code> represents the octal digits plus
-the lowercase letters plus the '<code>-</code>' character.
-
-
-<p>
-The interaction between ranges and classes is not defined.
-Therefore, patterns like <code>[%a-z]</code> or <code>[a-%%]</code>
-have no meaning.
-</li>
-
-<li><b><code>[^<em>set</em>]</code>:</b>
-represents the complement of <em>set</em>,
-where <em>set</em> is interpreted as above.
-</li>
-
-</ul><p>
-For all classes represented by single letters (<code>%a</code>, <code>%c</code>, etc.),
-the corresponding uppercase letter represents the complement of the class.
-For instance, <code>%S</code> represents all non-space characters.
-
-
-<p>
-The definitions of letter, space, and other character groups
-depend on the current locale.
-In particular, the class <code>[a-z]</code> may not be equivalent to <code>%l</code>.
-
-
-
-
-
-<h4>Pattern Item:</h4><p>
-A <em>pattern item</em> can be
-
-<ul>
-
-<li>
-a single character class,
-which matches any single character in the class;
-</li>
-
-<li>
-a single character class followed by '<code>*</code>',
-which matches 0 or more repetitions of characters in the class.
-These repetition items will always match the longest possible sequence;
-</li>
-
-<li>
-a single character class followed by '<code>+</code>',
-which matches 1 or more repetitions of characters in the class.
-These repetition items will always match the longest possible sequence;
-</li>
-
-<li>
-a single character class followed by '<code>-</code>',
-which also matches 0 or more repetitions of characters in the class.
-Unlike '<code>*</code>',
-these repetition items will always match the <em>shortest</em> possible sequence;
-</li>
-
-<li>
-a single character class followed by '<code>?</code>',
-which matches 0 or 1 occurrence of a character in the class;
-</li>
-
-<li>
-<code>%<em>n</em></code>, for <em>n</em> between 1 and 9;
-such item matches a substring equal to the <em>n</em>-th captured string
-(see below);
-</li>
-
-<li>
-<code>%b<em>xy</em></code>, where <em>x</em> and <em>y</em> are two distinct characters;
-such item matches strings that start with&nbsp;<em>x</em>, end with&nbsp;<em>y</em>,
-and where the <em>x</em> and <em>y</em> are <em>balanced</em>.
-This means that, if one reads the string from left to right,
-counting <em>+1</em> for an <em>x</em> and <em>-1</em> for a <em>y</em>,
-the ending <em>y</em> is the first <em>y</em> where the count reaches 0.
-For instance, the item <code>%b()</code> matches expressions with
-balanced parentheses.
-</li>
-
-</ul>
-
-
-
-
-<h4>Pattern:</h4><p>
-A <em>pattern</em> is a sequence of pattern items.
-A '<code>^</code>' at the beginning of a pattern anchors the match at the
-beginning of the subject string.
-A '<code>$</code>' at the end of a pattern anchors the match at the
-end of the subject string.
-At other positions,
-'<code>^</code>' and '<code>$</code>' have no special meaning and represent themselves.
-
-
-
-
-
-<h4>Captures:</h4><p>
-A pattern can contain sub-patterns enclosed in parentheses;
-they describe <em>captures</em>.
-When a match succeeds, the substrings of the subject string
-that match captures are stored (<em>captured</em>) for future use.
-Captures are numbered according to their left parentheses.
-For instance, in the pattern <code>"(a*(.)%w(%s*))"</code>,
-the part of the string matching <code>"a*(.)%w(%s*)"</code> is
-stored as the first capture (and therefore has number&nbsp;1);
-the character matching "<code>.</code>" is captured with number&nbsp;2,
-and the part matching "<code>%s*</code>" has number&nbsp;3.
-
-
-<p>
-As a special case, the empty capture <code>()</code> captures
-the current string position (a number).
-For instance, if we apply the pattern <code>"()aa()"</code> on the
-string <code>"flaaap"</code>, there will be two captures: 3&nbsp;and&nbsp;5.
-

-<h2>5.5 - <a name="5.5">Table Manipulation</a></h2><p>
-This library provides generic functions for table manipulation.
-It provides all its functions inside the table <a name="pdf-table"><code>table</code></a>.
-
-
-<p>
-Most functions in the table library assume that the table
-represents an array or a list.
-For these functions, when we talk about the "length" of a table
-we mean the result of the length operator.
-
-
-<p>
-<hr><h3><a name="pdf-table.concat"><code>table.concat (table [, sep [, i [, j]]])</code></a></h3>
-Given an array where all elements are strings or numbers,
-returns <code>table[i]..sep..table[i+1] &middot;&middot;&middot; sep..table[j]</code>.
-The default value for <code>sep</code> is the empty string,
-the default for <code>i</code> is 1,
-and the default for <code>j</code> is the length of the table.
-If <code>i</code> is greater than <code>j</code>, returns the empty string.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-table.insert"><code>table.insert (table, [pos,] value)</code></a></h3>
-
-
-<p>
-Inserts element <code>value</code> at position <code>pos</code> in <code>table</code>,
-shifting up other elements to open space, if necessary.
-The default value for <code>pos</code> is <code>n+1</code>,
-where <code>n</code> is the length of the table (see <a href="#2.5.5">&sect;2.5.5</a>),
-so that a call <code>table.insert(t,x)</code> inserts <code>x</code> at the end
-of table <code>t</code>.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-table.maxn"><code>table.maxn (table)</code></a></h3>
-
-
-<p>
-Returns the largest positive numerical index of the given table,
-or zero if the table has no positive numerical indices.
-(To do its job this function does a linear traversal of
-the whole table.) 
-
-
-
-
-<p>
-<hr><h3><a name="pdf-table.remove"><code>table.remove (table [, pos])</code></a></h3>
-
-
-<p>
-Removes from <code>table</code> the element at position <code>pos</code>,
-shifting down other elements to close the space, if necessary.
-Returns the value of the removed element.
-The default value for <code>pos</code> is <code>n</code>,
-where <code>n</code> is the length of the table,
-so that a call <code>table.remove(t)</code> removes the last element
-of table <code>t</code>.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-table.sort"><code>table.sort (table [, comp])</code></a></h3>
-Sorts table elements in a given order, <em>in-place</em>,
-from <code>table[1]</code> to <code>table[n]</code>,
-where <code>n</code> is the length of the table.
-If <code>comp</code> is given,
-then it must be a function that receives two table elements,
-and returns true
-when the first is less than the second
-(so that <code>not comp(a[i+1],a[i])</code> will be true after the sort).
-If <code>comp</code> is not given,
-then the standard Lua operator <code>&lt;</code> is used instead.
-
-
-<p>
-The sort algorithm is not stable;
-that is, elements considered equal by the given order
-may have their relative positions changed by the sort.

-<h2>5.7 - <a name="5.7">Input and Output Facilities</a></h2>
-
-<p>
-The I/O library provides two different styles for file manipulation.
-The first one uses implicit file descriptors;
-that is, there are operations to set a default input file and a
-default output file,
-and all input/output operations are over these default files.
-The second style uses explicit file descriptors.
-
-
-<p>
-When using implicit file descriptors,
-all operations are supplied by table <a name="pdf-io"><code>io</code></a>.
-When using explicit file descriptors,
-the operation <a href="#pdf-io.open"><code>io.open</code></a> returns a file descriptor
-and then all operations are supplied as methods of the file descriptor.
-
-
-<p>
-The table <code>io</code> also provides
-three predefined file descriptors with their usual meanings from C:
-<a name="pdf-io.stdin"><code>io.stdin</code></a>, <a name="pdf-io.stdout"><code>io.stdout</code></a>, and <a name="pdf-io.stderr"><code>io.stderr</code></a>.
-The I/O library never closes these files.
-
-
-<p>
-Unless otherwise stated,
-all I/O functions return <b>nil</b> on failure
-(plus an error message as a second result and
-a system-dependent error code as a third result)
-and some value different from <b>nil</b> on success.
-
-
-<p>
-<hr><h3><a name="pdf-io.close"><code>io.close ([file])</code></a></h3>
-
-
-<p>
-Equivalent to <code>file:close()</code>.
-Without a <code>file</code>, closes the default output file.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-io.flush"><code>io.flush ()</code></a></h3>
-
-
-<p>
-Equivalent to <code>file:flush</code> over the default output file.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-io.input"><code>io.input ([file])</code></a></h3>
-
-
-<p>
-When called with a file name, it opens the named file (in text mode),
-and sets its handle as the default input file.
-When called with a file handle,
-it simply sets this file handle as the default input file.
-When called without parameters,
-it returns the current default input file.
-
-
-<p>
-In case of errors this function raises the error,
-instead of returning an error code.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-io.lines"><code>io.lines ([filename])</code></a></h3>
-
-
-<p>
-Opens the given file name in read mode
-and returns an iterator function that,
-each time it is called,
-returns a new line from the file.
-Therefore, the construction
-
-<pre>
-     for line in io.lines(filename) do <em>body</em> end
-</pre><p>
-will iterate over all lines of the file.
-When the iterator function detects the end of file,
-it returns <b>nil</b> (to finish the loop) and automatically closes the file.
-
-
-<p>
-The call <code>io.lines()</code> (with no file name) is equivalent
-to <code>io.input():lines()</code>;
-that is, it iterates over the lines of the default input file.
-In this case it does not close the file when the loop ends.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-io.open"><code>io.open (filename [, mode])</code></a></h3>
-
-
-<p>
-This function opens a file,
-in the mode specified in the string <code>mode</code>.
-It returns a new file handle,
-or, in case of errors, <b>nil</b> plus an error message.
-
-
-<p>
-The <code>mode</code> string can be any of the following:
-
-<ul>
-<li><b>"r":</b> read mode (the default);</li>
-<li><b>"w":</b> write mode;</li>
-<li><b>"a":</b> append mode;</li>
-<li><b>"r+":</b> update mode, all previous data is preserved;</li>
-<li><b>"w+":</b> update mode, all previous data is erased;</li>
-<li><b>"a+":</b> append update mode, previous data is preserved,
-  writing is only allowed at the end of file.</li>
-</ul><p>
-The <code>mode</code> string can also have a '<code>b</code>' at the end,
-which is needed in some systems to open the file in binary mode.
-This string is exactly what is used in the
-standard&nbsp;C function <code>fopen</code>.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-io.output"><code>io.output ([file])</code></a></h3>
-
-
-<p>
-Similar to <a href="#pdf-io.input"><code>io.input</code></a>, but operates over the default output file.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-io.popen"><code>io.popen (prog [, mode])</code></a></h3>
-
-
-<p>
-Starts program <code>prog</code> in a separated process and returns
-a file handle that you can use to read data from this program
-(if <code>mode</code> is <code>"r"</code>, the default)
-or to write data to this program
-(if <code>mode</code> is <code>"w"</code>).
-
-
-<p>
-This function is system dependent and is not available
-on all platforms.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-io.read"><code>io.read (&middot;&middot;&middot;)</code></a></h3>
-
-
-<p>
-Equivalent to <code>io.input():read</code>.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-io.tmpfile"><code>io.tmpfile ()</code></a></h3>
-
-
-<p>
-Returns a handle for a temporary file.
-This file is opened in update mode
-and it is automatically removed when the program ends.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-io.type"><code>io.type (obj)</code></a></h3>
-
-
-<p>
-Checks whether <code>obj</code> is a valid file handle.
-Returns the string <code>"file"</code> if <code>obj</code> is an open file handle,
-<code>"closed file"</code> if <code>obj</code> is a closed file handle,
-or <b>nil</b> if <code>obj</code> is not a file handle.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-io.write"><code>io.write (&middot;&middot;&middot;)</code></a></h3>
-
-
-<p>
-Equivalent to <code>io.output():write</code>.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-file:close"><code>file:close ()</code></a></h3>
-
-
-<p>
-Closes <code>file</code>.
-Note that files are automatically closed when
-their handles are garbage collected,
-but that takes an unpredictable amount of time to happen.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-file:flush"><code>file:flush ()</code></a></h3>
-
-
-<p>
-Saves any written data to <code>file</code>.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-file:lines"><code>file:lines ()</code></a></h3>
-
-
-<p>
-Returns an iterator function that,
-each time it is called,
-returns a new line from the file.
-Therefore, the construction
-
-<pre>
-     for line in file:lines() do <em>body</em> end
-</pre><p>
-will iterate over all lines of the file.
-(Unlike <a href="#pdf-io.lines"><code>io.lines</code></a>, this function does not close the file
-when the loop ends.)
-
-
-
-
-<p>
-<hr><h3><a name="pdf-file:read"><code>file:read (&middot;&middot;&middot;)</code></a></h3>
-
-
-<p>
-Reads the file <code>file</code>,
-according to the given formats, which specify what to read.
-For each format,
-the function returns a string (or a number) with the characters read,
-or <b>nil</b> if it cannot read data with the specified format.
-When called without formats,
-it uses a default format that reads the entire next line
-(see below).
-
-
-<p>
-The available formats are
-
-<ul>
-
-<li><b>"*n":</b>
-reads a number;
-this is the only format that returns a number instead of a string.
-</li>
-
-<li><b>"*a":</b>
-reads the whole file, starting at the current position.
-On end of file, it returns the empty string.
-</li>
-
-<li><b>"*l":</b>
-reads the next line (skipping the end of line),
-returning <b>nil</b> on end of file.
-This is the default format.
-</li>
-
-<li><b><em>number</em>:</b>
-reads a string with up to this number of characters,
-returning <b>nil</b> on end of file.
-If number is zero,
-it reads nothing and returns an empty string,
-or <b>nil</b> on end of file.
-</li>
-
-</ul>
-
-
-
-<p>
-<hr><h3><a name="pdf-file:seek"><code>file:seek ([whence] [, offset])</code></a></h3>
-
-
-<p>
-Sets and gets the file position,
-measured from the beginning of the file,
-to the position given by <code>offset</code> plus a base
-specified by the string <code>whence</code>, as follows:
-
-<ul>
-<li><b>"set":</b> base is position 0 (beginning of the file);</li>
-<li><b>"cur":</b> base is current position;</li>
-<li><b>"end":</b> base is end of file;</li>
-</ul><p>
-In case of success, function <code>seek</code> returns the final file position,
-measured in bytes from the beginning of the file.
-If this function fails, it returns <b>nil</b>,
-plus a string describing the error.
-
-
-<p>
-The default value for <code>whence</code> is <code>"cur"</code>,
-and for <code>offset</code> is 0.
-Therefore, the call <code>file:seek()</code> returns the current
-file position, without changing it;
-the call <code>file:seek("set")</code> sets the position to the
-beginning of the file (and returns 0);
-and the call <code>file:seek("end")</code> sets the position to the
-end of the file, and returns its size.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-file:setvbuf"><code>file:setvbuf (mode [, size])</code></a></h3>
-
-
-<p>
-Sets the buffering mode for an output file.
-There are three available modes:
-
-<ul>
-
-<li><b>"no":</b>
-no buffering; the result of any output operation appears immediately.
-</li>
-
-<li><b>"full":</b>
-full buffering; output operation is performed only
-when the buffer is full (or when you explicitly <code>flush</code> the file
-(see <a href="#pdf-io.flush"><code>io.flush</code></a>)).
-</li>
-
-<li><b>"line":</b>
-line buffering; output is buffered until a newline is output
-or there is any input from some special files
-(such as a terminal device).
-</li>
-
-</ul><p>
-For the last two cases, <code>size</code>
-specifies the size of the buffer, in bytes.
-The default is an appropriate size.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-file:write"><code>file:write (&middot;&middot;&middot;)</code></a></h3>
-
-
-<p>
-Writes the value of each of its arguments to
-the <code>file</code>.
-The arguments must be strings or numbers.
-To write other values,
-use <a href="#pdf-tostring"><code>tostring</code></a> or <a href="#pdf-string.format"><code>string.format</code></a> before <code>write</code>.

-
-
-<p>
-<hr><h3><a name="pdf-os.clock"><code>os.clock ()</code></a></h3>
-
-
-<p>
-Returns an approximation of the amount in seconds of CPU time
-used by the program.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-os.date"><code>os.date ([format [, time]])</code></a></h3>
-
-
-<p>
-Returns a string or a table containing date and time,
-formatted according to the given string <code>format</code>.
-
-
-<p>
-If the <code>time</code> argument is present,
-this is the time to be formatted
-(see the <a href="#pdf-os.time"><code>os.time</code></a> function for a description of this value).
-Otherwise, <code>date</code> formats the current time.
-
-
-<p>
-If <code>format</code> starts with '<code>!</code>',
-then the date is formatted in Coordinated Universal Time.
-After this optional character,
-if <code>format</code> is the string "<code>*t</code>",
-then <code>date</code> returns a table with the following fields:
-<code>year</code> (four digits), <code>month</code> (1--12), <code>day</code> (1--31),
-<code>hour</code> (0--23), <code>min</code> (0--59), <code>sec</code> (0--61),
-<code>wday</code> (weekday, Sunday is&nbsp;1),
-<code>yday</code> (day of the year),
-and <code>isdst</code> (daylight saving flag, a boolean).
-
-
-<p>
-If <code>format</code> is not "<code>*t</code>",
-then <code>date</code> returns the date as a string,
-formatted according to the same rules as the C&nbsp;function <code>strftime</code>.
-
-
-<p>
-When called without arguments,
-<code>date</code> returns a reasonable date and time representation that depends on
-the host system and on the current locale
-(that is, <code>os.date()</code> is equivalent to <code>os.date("%c")</code>).

-<hr><h3><a name="pdf-os.execute"><code>os.execute ([command])</code></a></h3>
-
-
-<p>
-This function is equivalent to the C&nbsp;function <code>system</code>.
-It passes <code>command</code> to be executed by an operating system shell.
-It returns a status code, which is system-dependent.
-If <code>command</code> is absent, then it returns nonzero if a shell is available
-and zero otherwise.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-os.exit"><code>os.exit ([code])</code></a></h3>
-

-
-<p>
-<hr><h3><a name="pdf-os.remove"><code>os.remove (filename)</code></a></h3>
-
-
-<p>
-Deletes the file or directory with the given name.
-Directories must be empty to be removed.
-If this function fails, it returns <b>nil</b>,
-plus a string describing the error.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-os.rename"><code>os.rename (oldname, newname)</code></a></h3>
-
-
-<p>
-Renames file or directory named <code>oldname</code> to <code>newname</code>.
-If this function fails, it returns <b>nil</b>,
-plus a string describing the error.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-os.setlocale"><code>os.setlocale (locale [, category])</code></a></h3>
-
-
-<p>
-Sets the current locale of the program.
-<code>locale</code> is a string specifying a locale;
-<code>category</code> is an optional string describing which category to change:
-<code>"all"</code>, <code>"collate"</code>, <code>"ctype"</code>,
-<code>"monetary"</code>, <code>"numeric"</code>, or <code>"time"</code>;
-the default category is <code>"all"</code>.
-The function returns the name of the new locale,
-or <b>nil</b> if the request cannot be honored.
-
-
-<p>
-If <code>locale</code> is the empty string,
-the current locale is set to an implementation-defined native locale.
-If <code>locale</code> is the string "<code>C</code>",
-the current locale is set to the standard C locale.
-
-
-<p>
-When called with <b>nil</b> as the first argument,
-this function only returns the name of the current locale
-for the given category.
-
-
-

-<p>
-<hr><h3><a name="pdf-os.time"><code>os.time ([table])</code></a></h3>
-
-
-<p>
-Returns the current time when called without arguments,
-or a time representing the date and time specified by the given table.
-This table must have fields <code>year</code>, <code>month</code>, and <code>day</code>,
-and may have fields <code>hour</code>, <code>min</code>, <code>sec</code>, and <code>isdst</code>
-(for a description of these fields, see the <a href="#pdf-os.date"><code>os.date</code></a> function).
-
-
-<p>
-The returned value is a number, whose meaning depends on your system.
-In POSIX, Windows, and some other systems, this number counts the number
-of seconds since some given start time (the "epoch").
-In other systems, the meaning is not specified,
-and the number returned by <code>time</code> can be used only as an argument to
-<code>date</code> and <code>difftime</code>.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-os.tmpname"><code>os.tmpname ()</code></a></h3>
-
-
-<p>
-Returns a string with a file name that can
-be used for a temporary file.
-The file must be explicitly opened before its use
-and explicitly removed when no longer needed.
-
-
-<p>
-On some systems (POSIX),
-this function also creates a file with that name,
-to avoid security risks.
-(Someone else might create the file with wrong permissions
-in the time between getting the name and creating the file.)
-You still have to open the file to use it
-and to remove it (even if you do not use it).
-
-
-<p>
-When possible,
-you may prefer to use <a href="#pdf-io.tmpfile"><code>io.tmpfile</code></a>,
-which automatically removes the file when the program ends.

-<h2>5.9 - <a name="5.9">The Debug Library</a></h2>
-
-<p>
-This library provides
-the functionality of the debug interface to Lua programs.
-You should exert care when using this library.
-The functions provided here should be used exclusively for debugging
-and similar tasks, such as profiling.
-Please resist the temptation to use them as a
-usual programming tool:
-they can be very slow.
-Moreover, several of these functions
-violate some assumptions about Lua code
-(e.g., that variables local to a function
-cannot be accessed from outside or
-that userdata metatables cannot be changed by Lua code)
-and therefore can compromise otherwise secure code.
-
-
-<p>
-All functions in this library are provided
-inside the <a name="pdf-debug"><code>debug</code></a> table.
-All functions that operate over a thread
-have an optional first argument which is the
-thread to operate over.
-The default is always the current thread.
-
-
-<p>
-<hr><h3><a name="pdf-debug.debug"><code>debug.debug ()</code></a></h3>
-
-
-<p>
-Enters an interactive mode with the user,
-running each string that the user enters.
-Using simple commands and other debug facilities,
-the user can inspect global and local variables,
-change their values, evaluate expressions, and so on.
-A line containing only the word <code>cont</code> finishes this function,
-so that the caller continues its execution.
-
-
-<p>
-Note that commands for <code>debug.debug</code> are not lexically nested
-within any function, and so have no direct access to local variables.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-debug.getfenv"><code>debug.getfenv (o)</code></a></h3>
-Returns the environment of object <code>o</code>.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-debug.gethook"><code>debug.gethook ([thread])</code></a></h3>
-
-
-<p>
-Returns the current hook settings of the thread, as three values:
-the current hook function, the current hook mask,
-and the current hook count
-(as set by the <a href="#pdf-debug.sethook"><code>debug.sethook</code></a> function).
-
-
-
-
-<p>
-<hr><h3><a name="pdf-debug.getinfo"><code>debug.getinfo ([thread,] function [, what])</code></a></h3>
-
-
-<p>
-Returns a table with information about a function.
-You can give the function directly,
-or you can give a number as the value of <code>function</code>,
-which means the function running at level <code>function</code> of the call stack
-of the given thread:
-level&nbsp;0 is the current function (<code>getinfo</code> itself);
-level&nbsp;1 is the function that called <code>getinfo</code>;
-and so on.
-If <code>function</code> is a number larger than the number of active functions,
-then <code>getinfo</code> returns <b>nil</b>.
-
-
-<p>
-The returned table can contain all the fields returned by <a href="#lua_getinfo"><code>lua_getinfo</code></a>,
-with the string <code>what</code> describing which fields to fill in.
-The default for <code>what</code> is to get all information available,
-except the table of valid lines.
-If present,
-the option '<code>f</code>'
-adds a field named <code>func</code> with the function itself.
-If present,
-the option '<code>L</code>'
-adds a field named <code>activelines</code> with the table of
-valid lines.
-
-
-<p>
-For instance, the expression <code>debug.getinfo(1,"n").name</code> returns
-a table with a name for the current function,
-if a reasonable name can be found,
-and the expression <code>debug.getinfo(print)</code>
-returns a table with all available information
-about the <a href="#pdf-print"><code>print</code></a> function.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-debug.getlocal"><code>debug.getlocal ([thread,] level, local)</code></a></h3>
-
-
-<p>
-This function returns the name and the value of the local variable
-with index <code>local</code> of the function at level <code>level</code> of the stack.
-(The first parameter or local variable has index&nbsp;1, and so on,
-until the last active local variable.)
-The function returns <b>nil</b> if there is no local
-variable with the given index,
-and raises an error when called with a <code>level</code> out of range.
-(You can call <a href="#pdf-debug.getinfo"><code>debug.getinfo</code></a> to check whether the level is valid.)
-
-
-<p>
-Variable names starting with '<code>(</code>' (open parentheses)
-represent internal variables
-(loop control variables, temporaries, and C&nbsp;function locals).
-
-
-
-
-<p>
-<hr><h3><a name="pdf-debug.getmetatable"><code>debug.getmetatable (object)</code></a></h3>
-
-
-<p>
-Returns the metatable of the given <code>object</code>
-or <b>nil</b> if it does not have a metatable.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-debug.getregistry"><code>debug.getregistry ()</code></a></h3>
-
-
-<p>
-Returns the registry table (see <a href="#3.5">&sect;3.5</a>).
-
-
-
-
-<p>
-<hr><h3><a name="pdf-debug.getupvalue"><code>debug.getupvalue (func, up)</code></a></h3>
-
-
-<p>
-This function returns the name and the value of the upvalue
-with index <code>up</code> of the function <code>func</code>.
-The function returns <b>nil</b> if there is no upvalue with the given index.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-debug.setfenv"><code>debug.setfenv (object, table)</code></a></h3>
-
-
-<p>
-Sets the environment of the given <code>object</code> to the given <code>table</code>.
-Returns <code>object</code>.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-debug.sethook"><code>debug.sethook ([thread,] hook, mask [, count])</code></a></h3>
-
-
-<p>
-Sets the given function as a hook.
-The string <code>mask</code> and the number <code>count</code> describe
-when the hook will be called.
-The string mask may have the following characters,
-with the given meaning:
-
-<ul>
-<li><b><code>"c"</code>:</b> the hook is called every time Lua calls a function;</li>
-<li><b><code>"r"</code>:</b> the hook is called every time Lua returns from a function;</li>
-<li><b><code>"l"</code>:</b> the hook is called every time Lua enters a new line of code.</li>
-</ul><p>
-With a <code>count</code> different from zero,
-the hook is called after every <code>count</code> instructions.
-
-
-<p>
-When called without arguments,
-<a href="#pdf-debug.sethook"><code>debug.sethook</code></a> turns off the hook.
-
-
-<p>
-When the hook is called, its first parameter is a string
-describing the event that has triggered its call:
-<code>"call"</code>, <code>"return"</code> (or <code>"tail return"</code>,
-when simulating a return from a tail call),
-<code>"line"</code>, and <code>"count"</code>.
-For line events,
-the hook also gets the new line number as its second parameter.
-Inside a hook,
-you can call <code>getinfo</code> with level&nbsp;2 to get more information about
-the running function
-(level&nbsp;0 is the <code>getinfo</code> function,
-and level&nbsp;1 is the hook function),
-unless the event is <code>"tail return"</code>.
-In this case, Lua is only simulating the return,
-and a call to <code>getinfo</code> will return invalid data.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-debug.setlocal"><code>debug.setlocal ([thread,] level, local, value)</code></a></h3>
-
-
-<p>
-This function assigns the value <code>value</code> to the local variable
-with index <code>local</code> of the function at level <code>level</code> of the stack.
-The function returns <b>nil</b> if there is no local
-variable with the given index,
-and raises an error when called with a <code>level</code> out of range.
-(You can call <code>getinfo</code> to check whether the level is valid.)
-Otherwise, it returns the name of the local variable.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-debug.setmetatable"><code>debug.setmetatable (object, table)</code></a></h3>
-
-
-<p>
-Sets the metatable for the given <code>object</code> to the given <code>table</code>
-(which can be <b>nil</b>).
-
-
-
-
-<p>
-<hr><h3><a name="pdf-debug.setupvalue"><code>debug.setupvalue (func, up, value)</code></a></h3>
-
-
-<p>
-This function assigns the value <code>value</code> to the upvalue
-with index <code>up</code> of the function <code>func</code>.
-The function returns <b>nil</b> if there is no upvalue
-with the given index.
-Otherwise, it returns the name of the upvalue.
-
-
-
-
-<p>
-<hr><h3><a name="pdf-debug.traceback"><code>debug.traceback ([thread,] [message [, level]])</code></a></h3>
-
-
-<p>
-Returns a string with a traceback of the call stack.
-An optional <code>message</code> string is appended
-at the beginning of the traceback.
-An optional <code>level</code> number tells at which level
-to start the traceback
-(default is 1, the function calling <code>traceback</code>).

-<h1>6 - <a name="6">Lua Stand-alone</a></h1>
-
-<p>
-Although Lua has been designed as an extension language,
-to be embedded in a host C&nbsp;program,
-it is also frequently used as a stand-alone language.
-An interpreter for Lua as a stand-alone language,
-called simply <code>lua</code>,
-is provided with the standard distribution.
-The stand-alone interpreter includes
-all standard libraries, including the debug library.
-Its usage is:
-
-<pre>
-     lua [options] [script [args]]
-</pre><p>
-The options are:
-
-<ul>
-<li><b><code>-e <em>stat</em></code>:</b> executes string <em>stat</em>;</li>
-<li><b><code>-l <em>mod</em></code>:</b> "requires" <em>mod</em>;</li>
-<li><b><code>-i</code>:</b> enters interactive mode after running <em>script</em>;</li>
-<li><b><code>-v</code>:</b> prints version information;</li>
-<li><b><code>--</code>:</b> stops handling options;</li>
-<li><b><code>-</code>:</b> executes <code>stdin</code> as a file and stops handling options.</li>
-</ul><p>
-After handling its options, <code>lua</code> runs the given <em>script</em>,
-passing to it the given <em>args</em> as string arguments.
-When called without arguments,
-<code>lua</code> behaves as <code>lua -v -i</code>
-when the standard input (<code>stdin</code>) is a terminal,
-and as <code>lua -</code> otherwise.
-
-
-<p>
-Before running any argument,
-the interpreter checks for an environment variable <a name="pdf-LUA_INIT"><code>LUA_INIT</code></a>.
-If its format is <code>@<em>filename</em></code>,
-then <code>lua</code> executes the file.
-Otherwise, <code>lua</code> executes the string itself.
-
-
-<p>
-All options are handled in order, except <code>-i</code>.
-For instance, an invocation like
-
-<pre>
-     $ lua -e'a=1' -e 'print(a)' script.lua
-</pre><p>
-will first set <code>a</code> to 1, then print the value of <code>a</code> (which is '<code>1</code>'),
-and finally run the file <code>script.lua</code> with no arguments.
-(Here <code>$</code> is the shell prompt. Your prompt may be different.)
-
-
-<p>
-Before starting to run the script,
-<code>lua</code> collects all arguments in the command line
-in a global table called <code>arg</code>.
-The script name is stored at index 0,
-the first argument after the script name goes to index 1,
-and so on.
-Any arguments before the script name
-(that is, the interpreter name plus the options)
-go to negative indices.
-For instance, in the call
-
-<pre>
-     $ lua -la b.lua t1 t2
-</pre><p>
-the interpreter first runs the file <code>a.lua</code>,
-then creates a table
-
-<pre>
-     arg = { [-2] = "lua", [-1] = "-la",
-             [0] = "b.lua",
-             [1] = "t1", [2] = "t2" }
-</pre><p>
-and finally runs the file <code>b.lua</code>.
-The script is called with <code>arg[1]</code>, <code>arg[2]</code>, &middot;&middot;&middot;
-as arguments;
-it can also access these arguments with the vararg expression '<code>...</code>'.
-
-
-<p>
-In interactive mode,
-if you write an incomplete statement,
-the interpreter waits for its completion
-by issuing a different prompt.
-
-
-<p>
-If the global variable <a name="pdf-_PROMPT"><code>_PROMPT</code></a> contains a string,
-then its value is used as the prompt.
-Similarly, if the global variable <a name="pdf-_PROMPT2"><code>_PROMPT2</code></a> contains a string,
-its value is used as the secondary prompt
-(issued during incomplete statements).
-Therefore, both prompts can be changed directly on the command line
-or in any Lua programs by assigning to <code>_PROMPT</code>.
-See the next example:
-
-<pre>
-     $ lua -e"_PROMPT='myprompt&gt; '" -i
-</pre><p>
-(The outer pair of quotes is for the shell,
-the inner pair is for Lua.)
-Note the use of <code>-i</code> to enter interactive mode;
-otherwise,
-the program would just end silently
-right after the assignment to <code>_PROMPT</code>.
-
-
-<p>
-To allow the use of Lua as a
-script interpreter in Unix systems,
-the stand-alone interpreter skips
-the first line of a chunk if it starts with <code>#</code>.
-Therefore, Lua scripts can be made into executable programs
-by using <code>chmod +x</code> and the&nbsp;<code>#!</code> form,
-as in
-
-<pre>
-     #!/usr/local/bin/lua
-</pre><p>
-(Of course,
-the location of the Lua interpreter may be different in your machine.
-If <code>lua</code> is in your <code>PATH</code>,
-then 
-
-<pre>
-     #!/usr/bin/env lua
-</pre><p>
-is a more portable solution.)

-<h1>7 - <a name="7">Incompatibilities with the Previous Version</a></h1>
-
-<p>
-Here we list the incompatibilities that you may find when moving a program
-from Lua&nbsp;5.0 to Lua&nbsp;5.1.
-You can avoid most of the incompatibilities compiling Lua with
-appropriate options (see file <code>luaconf.h</code>).
-However,
-all these compatibility options will be removed in the next version of Lua.
-
-
-
-<h2>7.1 - <a name="7.1">Changes in the Language</a></h2>
-<ul>
-
-<li>
-The vararg system changed from the pseudo-argument <code>arg</code> with a
-table with the extra arguments to the vararg expression.
-(See compile-time option <code>LUA_COMPAT_VARARG</code> in <code>luaconf.h</code>.)
-</li>
-
-<li>
-There was a subtle change in the scope of the implicit
-variables of the <b>for</b> statement and for the <b>repeat</b> statement.
-</li>
-
-<li>
-The long string/long comment syntax (<code>[[<em>string</em>]]</code>)
-does not allow nesting.
-You can use the new syntax (<code>[=[<em>string</em>]=]</code>) in these cases.
-(See compile-time option <code>LUA_COMPAT_LSTR</code> in <code>luaconf.h</code>.)

-(See compile-time option <code>LUA_COMPAT_GFIND</code> in <code>luaconf.h</code>.)
-</li>
-
-<li>
-When <a href="#pdf-string.gsub"><code>string.gsub</code></a> is called with a function as its
-third argument,
-whenever this function returns <b>nil</b> or <b>false</b> the
-replacement string is the whole match,
-instead of the empty string.
-</li>
-
-<li>
-Function <code>table.setn</code> was deprecated.
-Function <code>table.getn</code> corresponds
-to the new length operator (<code>#</code>);
-use the operator instead of the function.
-(See compile-time option <code>LUA_COMPAT_GETN</code> in <code>luaconf.h</code>.)
-</li>
-
-<li>
-Function <code>loadlib</code> was renamed <a href="#pdf-package.loadlib"><code>package.loadlib</code></a>.

-Functions <code>table.foreach</code> and <code>table.foreachi</code> are deprecated.
-You can use a for loop with <code>pairs</code> or <code>ipairs</code> instead.
-</li>
-
-<li>
-There were substantial changes in function <a href="#pdf-require"><code>require</code></a> due to
-the new module system.
-However, the new behavior is mostly compatible with the old,

-The <code>luaopen_*</code> functions (to open libraries)
-cannot be called directly,
-like a regular C function.
-They must be called through Lua,
-like a Lua function.
-</li>
-
-<li>
-Function <code>lua_open</code> was replaced by <a href="#lua_newstate"><code>lua_newstate</code></a> to

-This directory contains some useful files and code.
-Unlike the code in ../src, everything here is in the public domain.
-
-If any of the makes fail, you're probably not using the same libraries
-used to build Lua. Set MYLIBS in Makefile accordingly.
-
-all.c
-	Full Lua interpreter in a single file.
-	Do "make one" for a demo.
-
-lua.hpp
-	Lua header files for C++ using 'extern "C"'.
-
-lua.ico
-	A Lua icon for Windows (and web sites: save as favicon.ico).
-	Drawn by hand by Markus Gritsch <gritsch@iue.tuwien.ac.at>.
-
-lua.pc
-	pkg-config data for Lua
-
-luavs.bat
-	Script to build Lua under "Visual Studio .NET Command Prompt".
-	Run it from the toplevel as etc\luavs.bat.
-
-min.c
-	A minimal Lua interpreter.
-	Good for learning and for starting your own.
-	Do "make min" for a demo.
-
-noparser.c
-	Linking with noparser.o avoids loading the parsing modules in lualib.a.
-	Do "make noparser" for a demo.
-
-strict.lua
-	Traps uses of undeclared global variables.
-	Do "make strict" for a demo.

-  We assume that instructions are unsigned numbers.
-  All instructions have an opcode in the first 6 bits.
-  Instructions can have the following fields:
-	`A' : 8 bits
-	`B' : 9 bits
-	`C' : 9 bits
-	`Bx' : 18 bits (`B' and `C' together)
-	`sBx' : signed Bx
-
-  A signed argument is represented in excess K; that is, the number
-  value is the unsigned value minus K. K is exactly the maximum value
-  for that argument (so that -max is represented by 0, and +max is
-  represented by 2*max), which is half the maximum for the corresponding

+# Lua
+
+[Lua](https://www.lua.org/) is a powerful, fast, lightweight, embeddable scripting language.
+
+Lua combines simple procedural syntax with powerful data description constructs based on associative arrays and extensible semantics. Lua is dynamically typed, runs by interpreting bytecode for a register-based virtual machine, and has automatic memory management with incremental garbage collection, making it ideal for configuration, scripting, and rapid prototyping.
+
+Lua is free open-source software, distributed under a very liberal license (the well-known MIT license).

+.SH NAME
+lua \- Lua interpreter
+.SH SYNOPSIS
+.B lua
+[
+.I options
+]
+[
+.I script
+[
+.I args
+]
+]
+.SH DESCRIPTION
+.B lua
+is the standalone Lua interpreter.
+It loads and executes Lua programs,
+either in textual source form or
+in precompiled binary form.
+(Precompiled binaries are output by
+.BR luac ,
+the Lua compiler.)
+.B lua
+can be used as a batch interpreter and also interactively.
+.LP
+After handling the
+.IR options ,
+the Lua program in file
+.I script
+is loaded and executed.
+The
+.I args
+are available to
+.I script
+as strings in a global table named
+.B arg
+and also as arguments to its main function.
+When called without arguments,
+.B lua
+behaves as
+.B "lua \-v \-i"
+if the standard input is a terminal,
+and as
+.B "lua \-"
+otherwise.
+.LP
+In interactive mode,
+.B lua
+prompts the user,
+reads lines from the standard input,
+and executes them as they are read.
+If the line contains an expression,
+then the line is evaluated and the result is printed.
+If a line does not contain a complete statement,
+then a secondary prompt is displayed and
+lines are read until a complete statement is formed or
+a syntax error is found.
+.LP
+Before handling command line options and scripts,
+.B lua
+checks the contents of the environment variables
+.B LUA_INIT_5_4
+and
+.BR LUA_INIT ,
+in that order.
+If the contents are of the form
+.RI '@ filename ',
+then
+.I filename
+is executed.
+Otherwise, the contents are assumed to be a Lua statement and is executed.
+When
+.B LUA_INIT_5_4
+is defined,
+.B LUA_INIT
+is ignored.
+.SH OPTIONS
+.TP
+.BI \-e " stat"
+execute statement
+.IR stat .
+.TP
+.B \-i
+enter interactive mode after executing
+.IR script .
+.TP
+.BI \-l " mod"
+require library
+.I mod
+into global
+.IR mod .
+.TP
+.BI \-l " g=mod"
+require library
+.I mod
+into global
+.IR g .
+.TP
+.B \-v
+show version information.
+.TP
+.B \-E
+ignore environment variables.
+.TP
+.B \-W
+turn warnings on.
+.TP
+.B \-\-
+stop handling options.
+.TP

+<h1>1 &ndash; <a name="1">Introduction</a></h1>
+
+<p>
+Lua is a powerful, efficient, lightweight, embeddable scripting language.
+It supports procedural programming,
+object-oriented programming, functional programming,
+data-driven programming, and data description.
+
+
+<p>
+Lua combines simple procedural syntax with powerful data description
+constructs based on associative arrays and extensible semantics.
+Lua is dynamically typed,
+runs by interpreting bytecode with a register-based
+virtual machine,
+and has automatic memory management with
+a generational garbage collection,
+making it ideal for configuration, scripting,
+and rapid prototyping.
+
+
+<p>
+Lua is implemented as a library, written in <em>clean C</em>,
+the common subset of standard&nbsp;C and C++.
+The Lua distribution includes a host program called <code>lua</code>,
+which uses the Lua library to offer a complete,
+standalone Lua interpreter,
+for interactive or batch use.
+Lua is intended to be used both as a powerful, lightweight,
+embeddable scripting language for any program that needs one,
+and as a powerful but lightweight and efficient stand-alone language.
+
+
+<p>
+As an extension language, Lua has no notion of a "main" program:
+it works <em>embedded</em> in a host client,
+called the <em>embedding program</em> or simply the <em>host</em>.
+(Frequently, this host is the stand-alone <code>lua</code> program.)
+The host program can invoke functions to execute a piece of Lua code,
+can write and read Lua variables,
+and can register C&nbsp;functions to be called by Lua code.
+Through the use of C&nbsp;functions, Lua can be augmented to cope with
+a wide range of different domains,
+thus creating customized programming languages sharing a syntactical framework.
+
+
+<p>
+Lua is free software,
+and is provided as usual with no guarantees,
+as stated in its license.
+The implementation described in this manual is available
+at Lua's official web site, <code>www.lua.org</code>.
+
+
+<p>
+Like any other reference manual,
+this document is dry in places.
+For a discussion of the decisions behind the design of Lua,
+see the technical papers available at Lua's web site.
+For a detailed introduction to programming in Lua,
+see Roberto's book, <em>Programming in Lua</em>.
+
+
+
+<h1>2 &ndash; <a name="2">Basic Concepts</a></h1>
+
+
+
+<p>
+This section describes the basic concepts of the language.
+
+
+
+
+
+<h2>2.1 &ndash; <a name="2.1">Values and Types</a></h2>
+
+<p>
+Lua is a dynamically typed language.
+This means that
+variables do not have types; only values do.
+There are no type definitions in the language.
+All values carry their own type.
+
+
+<p>
+All values in Lua are first-class values.
+This means that all values can be stored in variables,
+passed as arguments to other functions, and returned as results.
+
+
+<p>
+There are eight basic types in Lua:
+<em>nil</em>, <em>boolean</em>, <em>number</em>,
+<em>string</em>, <em>function</em>, <em>userdata</em>,
+<em>thread</em>, and <em>table</em>.
+The type <em>nil</em> has one single value, <b>nil</b>,
+whose main property is to be different from any other value;
+it often represents the absence of a useful value.
+The type <em>boolean</em> has two values, <b>false</b> and <b>true</b>.
+Both <b>nil</b> and <b>false</b> make a condition false;
+they are collectively called <em>false values</em>.
+Any other value makes a condition true.
+Despite its name,
+<b>false</b> is frequently used as an alternative to <b>nil</b>,
+with the key difference that <b>false</b> behaves
+like a regular value in a table,
+while a <b>nil</b> in a table represents an absent key.
+
+
+<p>
+The type <em>number</em> represents both
+integer numbers and real (floating-point) numbers,
+using two subtypes: <em>integer</em> and <em>float</em>.
+Standard Lua uses 64-bit integers and double-precision (64-bit) floats,
+but you can also compile Lua so that it
+uses 32-bit integers and/or single-precision (32-bit) floats.
+The option with 32 bits for both integers and floats
+is particularly attractive
+for small machines and embedded systems.
+(See macro <code>LUA_32BITS</code> in file <code>luaconf.h</code>.)
+
+
+<p>
+Unless stated otherwise,
+any overflow when manipulating integer values <em>wrap around</em>,
+according to the usual rules of two-complement arithmetic.
+(In other words,
+the actual result is the unique representable integer
+that is equal modulo <em>2<sup>n</sup></em> to the mathematical result,
+where <em>n</em> is the number of bits of the integer type.)
+
+
+<p>
+Lua has explicit rules about when each subtype is used,
+but it also converts between them automatically as needed (see <a href="#3.4.3">&sect;3.4.3</a>).
+Therefore,
+the programmer may choose to mostly ignore the difference
+between integers and floats
+or to assume complete control over the representation of each number.
+
+
+<p>
+The type <em>string</em> represents immutable sequences of bytes.
+
+Lua is 8-bit clean:
+strings can contain any 8-bit value,
+including embedded zeros ('<code>\0</code>').
+Lua is also encoding-agnostic;
+it makes no assumptions about the contents of a string.
+The length of any string in Lua must fit in a Lua integer.
+
+
+<p>
+Lua can call (and manipulate) functions written in Lua and
+functions written in C (see <a href="#3.4.10">&sect;3.4.10</a>).
+Both are represented by the type <em>function</em>.
+
+
+<p>
+The type <em>userdata</em> is provided to allow arbitrary C&nbsp;data to
+be stored in Lua variables.
+A userdata value represents a block of raw memory.
+There are two kinds of userdata:
+<em>full userdata</em>,
+which is an object with a block of memory managed by Lua,
+and <em>light userdata</em>,
+which is simply a C&nbsp;pointer value.
+Userdata has no predefined operations in Lua,
+except assignment and identity test.
+By using <em>metatables</em>,
+the programmer can define operations for full userdata values
+(see <a href="#2.4">&sect;2.4</a>).
+Userdata values cannot be created or modified in Lua,
+only through the C&nbsp;API.
+This guarantees the integrity of data owned by
+the host program and C&nbsp;libraries.
+
+
+<p>
+The type <em>thread</em> represents independent threads of execution
+and it is used to implement coroutines (see <a href="#2.6">&sect;2.6</a>).
+Lua threads are not related to operating-system threads.
+Lua supports coroutines on all systems,
+even those that do not support threads natively.
+
+
+<p>
+The type <em>table</em> implements associative arrays,
+that is, arrays that can have as indices not only numbers,
+but any Lua value except <b>nil</b> and NaN.
+(<em>Not a Number</em> is a special floating-point value
+used by the IEEE 754 standard to represent
+undefined numerical results, such as <code>0/0</code>.)
+Tables can be <em>heterogeneous</em>;
+that is, they can contain values of all types (except <b>nil</b>).
+Any key associated to the value <b>nil</b> is not considered part of the table.
+Conversely, any key that is not part of a table has
+an associated value <b>nil</b>.
+
+
+<p>
+Tables are the sole data-structuring mechanism in Lua;
+they can be used to represent ordinary arrays, lists,
+symbol tables, sets, records, graphs, trees, etc.
+To represent records, Lua uses the field name as an index.
+The language supports this representation by
+providing <code>a.name</code> as syntactic sugar for <code>a["name"]</code>.
+There are several convenient ways to create tables in Lua
+(see <a href="#3.4.9">&sect;3.4.9</a>).
+
+
+<p>
+Like indices,
+the values of table fields can be of any type.
+In particular,
+because functions are first-class values,
+table fields can contain functions.
+Thus tables can also carry <em>methods</em> (see <a href="#3.4.11">&sect;3.4.11</a>).
+
+
+<p>
+The indexing of tables follows
+the definition of raw equality in the language.
+The expressions <code>a[i]</code> and <code>a[j]</code>
+denote the same table element
+if and only if <code>i</code> and <code>j</code> are raw equal
+(that is, equal without metamethods).
+In particular, floats with integral values
+are equal to their respective integers
+(e.g., <code>1.0 == 1</code>).
+To avoid ambiguities,
+any float used as a key that is equal to an integer
+is converted to that integer.
+For instance, if you write <code>a[2.0] = true</code>,
+the actual key inserted into the table will be the integer <code>2</code>.
+
+
+<p>
+Tables, functions, threads, and (full) userdata values are <em>objects</em>:
+variables do not actually <em>contain</em> these values,
+only <em>references</em> to them.
+Assignment, parameter passing, and function returns
+always manipulate references to such values;
+these operations do not imply any kind of copy.
+
+
+<p>
+The library function <a href="#pdf-type"><code>type</code></a> returns a string describing the type
+of a given value (see <a href="#pdf-type"><code>type</code></a>).
+
+
+
+
+
+<h2>2.2 &ndash; <a name="2.2">Environments and the Global Environment</a></h2>
+
+<p>
+As we will discuss further in <a href="#3.2">&sect;3.2</a> and <a href="#3.3.3">&sect;3.3.3</a>,
+any reference to a free name
+(that is, a name not bound to any declaration) <code>var</code>
+is syntactically translated to <code>_ENV.var</code>.
+Moreover, every chunk is compiled in the scope of
+an external local variable named <code>_ENV</code> (see <a href="#3.3.2">&sect;3.3.2</a>),
+so <code>_ENV</code> itself is never a free name in a chunk.
+
+
+<p>
+Despite the existence of this external <code>_ENV</code> variable and
+the translation of free names,
+<code>_ENV</code> is a completely regular name.
+In particular,
+you can define new variables and parameters with that name.
+Each reference to a free name uses the <code>_ENV</code> that is
+visible at that point in the program,
+following the usual visibility rules of Lua (see <a href="#3.5">&sect;3.5</a>).
+
+
+<p>
+Any table used as the value of <code>_ENV</code> is called an <em>environment</em>.
+
+
+<p>
+Lua keeps a distinguished environment called the <em>global environment</em>.
+This value is kept at a special index in the C registry (see <a href="#4.3">&sect;4.3</a>).
+In Lua, the global variable <a href="#pdf-_G"><code>_G</code></a> is initialized with this same value.
+(<a href="#pdf-_G"><code>_G</code></a> is never used internally,
+so changing its value will affect only your own code.)
+
+
+<p>
+When Lua loads a chunk,
+the default value for its <code>_ENV</code> variable
+is the global environment (see <a href="#pdf-load"><code>load</code></a>).
+Therefore, by default,
+free names in Lua code refer to entries in the global environment
+and, therefore, they are also called <em>global variables</em>.
+Moreover, all standard libraries are loaded in the global environment
+and some functions there operate on that environment.
+You can use <a href="#pdf-load"><code>load</code></a> (or <a href="#pdf-loadfile"><code>loadfile</code></a>)
+to load a chunk with a different environment.
+(In C, you have to load the chunk and then change the value
+of its first upvalue; see <a href="#lua_setupvalue"><code>lua_setupvalue</code></a>.)

+
+<h2>2.3 &ndash; <a name="2.3">Error Handling</a></h2>
+
+<p>
+Several operations in Lua can <em>raise</em> an error.
+An error interrupts the normal flow of the program,
+which can continue by <em>catching</em> the error.
+
+
+<p>
+Lua code can explicitly raise an error by calling the
+<a href="#pdf-error"><code>error</code></a> function.
+(This function never returns.)
+
+
+<p>
+To catch errors in Lua,
+you can do a <em>protected call</em>,
+using <a href="#pdf-pcall"><code>pcall</code></a> (or <a href="#pdf-xpcall"><code>xpcall</code></a>).
+The function <a href="#pdf-pcall"><code>pcall</code></a> calls a given function in <em>protected mode</em>.
+Any error while running the function stops its execution,
+and control returns immediately to <code>pcall</code>,
+which returns a status code.
+
+
+<p>
+Because Lua is an embedded extension language,
+Lua code starts running by a call
+from C&nbsp;code in the host program.
+(When you use Lua standalone,
+the <code>lua</code> application is the host program.)
+Usually, this call is protected;
+so, when an otherwise unprotected error occurs during
+the compilation or execution of a Lua chunk,
+control returns to the host,
+which can take appropriate measures,
+such as printing an error message.
+
+
+<p>
+Whenever there is an error,
+an <em>error object</em>
+is propagated with information about the error.
+Lua itself only generates errors whose error object is a string,
+but programs may generate errors with
+any value as the error object.
+It is up to the Lua program or its host to handle such error objects.
+For historical reasons,
+an error object is often called an <em>error message</em>,
+even though it does not have to be a string.
+
+
+<p>
+When you use <a href="#pdf-xpcall"><code>xpcall</code></a> (or <a href="#lua_pcall"><code>lua_pcall</code></a>, in C)
+you may give a <em>message handler</em>
+to be called in case of errors.
+This function is called with the original error object
+and returns a new error object.
+It is called before the error unwinds the stack,
+so that it can gather more information about the error,
+for instance by inspecting the stack and creating a stack traceback.
+This message handler is still protected by the protected call;
+so, an error inside the message handler
+will call the message handler again.
+If this loop goes on for too long,
+Lua breaks it and returns an appropriate message.
+The message handler is called only for regular runtime errors.
+It is not called for memory-allocation errors
+nor for errors while running finalizers or other message handlers.
+
+
+<p>
+Lua also offers a system of <em>warnings</em> (see <a href="#pdf-warn"><code>warn</code></a>).
+Unlike errors, warnings do not interfere
+in any way with program execution.
+They typically only generate a message to the user,
+although this behavior can be adapted from C (see <a href="#lua_setwarnf"><code>lua_setwarnf</code></a>).
+
+
+
+
+
+<h2>2.4 &ndash; <a name="2.4">Metatables and Metamethods</a></h2>
+
+<p>
+Every value in Lua can have a <em>metatable</em>.
+This <em>metatable</em> is an ordinary Lua table
+that defines the behavior of the original value
+under certain events.
+You can change several aspects of the behavior
+of a value by setting specific fields in its metatable.
+For instance, when a non-numeric value is the operand of an addition,
+Lua checks for a function in the field <code>__add</code> of the value's metatable.
+If it finds one,
+Lua calls this function to perform the addition.
+
+
+<p>
+The key for each event in a metatable is a string
+with the event name prefixed by two underscores;
+the corresponding value is called a <em>metavalue</em>.
+For most events, the metavalue must be a function,
+which is then called a <em>metamethod</em>.
+In the previous example, the key is the string "<code>__add</code>"
+and the metamethod is the function that performs the addition.
+Unless stated otherwise,
+a metamethod may in fact be any callable value,
+which is either a function or a value with a <code>__call</code> metamethod.
+
+
+<p>
+You can query the metatable of any value
+using the <a href="#pdf-getmetatable"><code>getmetatable</code></a> function.
+Lua queries metamethods in metatables using a raw access (see <a href="#pdf-rawget"><code>rawget</code></a>).
+
+
+<p>
+You can replace the metatable of tables
+using the <a href="#pdf-setmetatable"><code>setmetatable</code></a> function.
+You cannot change the metatable of other types from Lua code,
+except by using the debug library (<a href="#6.10">&sect;6.10</a>).
+
+
+<p>
+Tables and full userdata have individual metatables,
+although multiple tables and userdata can share their metatables.
+Values of all other types share one single metatable per type;
+that is, there is one single metatable for all numbers,
+one for all strings, etc.
+By default, a value has no metatable,
+but the string library sets a metatable for the string type (see <a href="#6.4">&sect;6.4</a>).
+
+
+<p>
+A detailed list of operations controlled by metatables is given next.
+Each event is identified by its corresponding key.
+By convention, all metatable keys used by Lua are composed by
+two underscores followed by lowercase Latin letters.
+
+
+
+<ul>
+
+<li><b><code>__add</code>: </b>
+the addition (<code>+</code>) operation.
+If any operand for an addition is not a number,
+Lua will try to call a metamethod.
+It starts by checking the first operand (even if it is a number);
+if that operand does not define a metamethod for <code>__add</code>,
+then Lua will check the second operand.
+If Lua can find a metamethod,
+it calls the metamethod with the two operands as arguments,
+and the result of the call
+(adjusted to one value)
+is the result of the operation.
+Otherwise, if no metamethod is found,
+Lua raises an error.
+</li>
+
+<li><b><code>__sub</code>: </b>
+the subtraction (<code>-</code>) operation.
+Behavior similar to the addition operation.
+</li>
+
+<li><b><code>__mul</code>: </b>
+the multiplication (<code>*</code>) operation.
+Behavior similar to the addition operation.
+</li>
+
+<li><b><code>__div</code>: </b>
+the division (<code>/</code>) operation.
+Behavior similar to the addition operation.
+</li>
+
+<li><b><code>__mod</code>: </b>
+the modulo (<code>%</code>) operation.
+Behavior similar to the addition operation.
+</li>
+
+<li><b><code>__pow</code>: </b>
+the exponentiation (<code>^</code>) operation.
+Behavior similar to the addition operation.
+</li>
+
+<li><b><code>__unm</code>: </b>
+the negation (unary <code>-</code>) operation.
+Behavior similar to the addition operation.
+</li>
+
+<li><b><code>__idiv</code>: </b>
+the floor division (<code>//</code>) operation.
+Behavior similar to the addition operation.
+</li>
+
+<li><b><code>__band</code>: </b>
+the bitwise AND (<code>&amp;</code>) operation.
+Behavior similar to the addition operation,
+except that Lua will try a metamethod
+if any operand is neither an integer
+nor a float coercible to an integer (see <a href="#3.4.3">&sect;3.4.3</a>).
+</li>
+
+<li><b><code>__bor</code>: </b>
+the bitwise OR (<code>|</code>) operation.
+Behavior similar to the bitwise AND operation.
+</li>
+
+<li><b><code>__bxor</code>: </b>
+the bitwise exclusive OR (binary <code>~</code>) operation.
+Behavior similar to the bitwise AND operation.
+</li>
+
+<li><b><code>__bnot</code>: </b>
+the bitwise NOT (unary <code>~</code>) operation.
+Behavior similar to the bitwise AND operation.
+</li>
+
+<li><b><code>__shl</code>: </b>
+the bitwise left shift (<code>&lt;&lt;</code>) operation.
+Behavior similar to the bitwise AND operation.
+</li>
+
+<li><b><code>__shr</code>: </b>
+the bitwise right shift (<code>&gt;&gt;</code>) operation.
+Behavior similar to the bitwise AND operation.
+</li>
+
+<li><b><code>__concat</code>: </b>
+the concatenation (<code>..</code>) operation.
+Behavior similar to the addition operation,
+except that Lua will try a metamethod
+if any operand is neither a string nor a number
+(which is always coercible to a string).
+</li>
+
+<li><b><code>__len</code>: </b>
+the length (<code>#</code>) operation.
+If the object is not a string,
+Lua will try its metamethod.
+If there is a metamethod,
+Lua calls it with the object as argument,
+and the result of the call
+(always adjusted to one value)
+is the result of the operation.
+If there is no metamethod but the object is a table,
+then Lua uses the table length operation (see <a href="#3.4.7">&sect;3.4.7</a>).
+Otherwise, Lua raises an error.
+</li>
+
+<li><b><code>__eq</code>: </b>
+the equal (<code>==</code>) operation.
+Behavior similar to the addition operation,
+except that Lua will try a metamethod only when the values
+being compared are either both tables or both full userdata
+and they are not primitively equal.
+The result of the call is always converted to a boolean.
+</li>
+
+<li><b><code>__lt</code>: </b>
+the less than (<code>&lt;</code>) operation.
+Behavior similar to the addition operation,
+except that Lua will try a metamethod only when the values
+being compared are neither both numbers nor both strings.
+Moreover, the result of the call is always converted to a boolean.
+</li>
+
+<li><b><code>__le</code>: </b>
+the less equal (<code>&lt;=</code>) operation.
+Behavior similar to the less than operation.
+</li>
+
+<li><b><code>__index</code>: </b>
+The indexing access operation <code>table[key]</code>.
+This event happens when <code>table</code> is not a table or
+when <code>key</code> is not present in <code>table</code>.
+The metavalue is looked up in the metatable of <code>table</code>.
+
+
+<p>
+The metavalue for this event can be either a function, a table,
+or any value with an <code>__index</code> metavalue.
+If it is a function,
+it is called with <code>table</code> and <code>key</code> as arguments,
+and the result of the call
+(adjusted to one value)
+is the result of the operation.
+Otherwise,
+the final result is the result of indexing this metavalue with <code>key</code>.
+This indexing is regular, not raw,
+and therefore can trigger another <code>__index</code> metavalue.
+</li>
+
+<li><b><code>__newindex</code>: </b>
+The indexing assignment <code>table[key] = value</code>.
+Like the index event,
+this event happens when <code>table</code> is not a table or
+when <code>key</code> is not present in <code>table</code>.
+The metavalue is looked up in the metatable of <code>table</code>.
+
+
+<p>
+Like with indexing,
+the metavalue for this event can be either a function, a table,
+or any value with an <code>__newindex</code> metavalue.
+If it is a function,
+it is called with <code>table</code>, <code>key</code>, and <code>value</code> as arguments.
+Otherwise,
+Lua repeats the indexing assignment over this metavalue
+with the same key and value.
+This assignment is regular, not raw,
+and therefore can trigger another <code>__newindex</code> metavalue.
+
+
+<p>
+Whenever a <code>__newindex</code> metavalue is invoked,
+Lua does not perform the primitive assignment.
+If needed,
+the metamethod itself can call <a href="#pdf-rawset"><code>rawset</code></a>
+to do the assignment.
+</li>
+
+<li><b><code>__call</code>: </b>
+The call operation <code>func(args)</code>.
+This event happens when Lua tries to call a non-function value
+(that is, <code>func</code> is not a function).
+The metamethod is looked up in <code>func</code>.
+If present,
+the metamethod is called with <code>func</code> as its first argument,
+followed by the arguments of the original call (<code>args</code>).
+All results of the call
+are the results of the operation.
+This is the only metamethod that allows multiple results.
+</li>
+
+</ul>
+
+<p>
+In addition to the previous list,
+the interpreter also respects the following keys in metatables:
+<code>__gc</code> (see <a href="#2.5.3">&sect;2.5.3</a>),
+<code>__close</code> (see <a href="#3.3.8">&sect;3.3.8</a>),
+<code>__mode</code> (see <a href="#2.5.4">&sect;2.5.4</a>),
+and <code>__name</code>.
+(The entry <code>__name</code>,
+when it contains a string,
+may be used by <a href="#pdf-tostring"><code>tostring</code></a> and in error messages.)
+
+
+<p>
+For the unary operators (negation, length, and bitwise NOT),
+the metamethod is computed and called with a dummy second operand,
+equal to the first one.
+This extra operand is only to simplify Lua's internals
+(by making these operators behave like a binary operation)
+and may be removed in future versions.
+For most uses this extra operand is irrelevant.
+
+
+<p>
+Because metatables are regular tables,
+they can contain arbitrary fields,
+not only the event names defined above.
+Some functions in the standard library
+(e.g., <a href="#pdf-tostring"><code>tostring</code></a>)
+use other fields in metatables for their own purposes.
+
+
+<p>
+It is a good practice to add all needed metamethods to a table
+before setting it as a metatable of some object.
+In particular, the <code>__gc</code> metamethod works only when this order
+is followed (see <a href="#2.5.3">&sect;2.5.3</a>).
+It is also a good practice to set the metatable of an object
+right after its creation.
+
+
+
+
+
+<h2>2.5 &ndash; <a name="2.5">Garbage Collection</a></h2>
+
+
+
+<p>
+Lua performs automatic memory management.
+This means that
+you do not have to worry about allocating memory for new objects
+or freeing it when the objects are no longer needed.
+Lua manages memory automatically by running
+a <em>garbage collector</em> to collect all <em>dead</em> objects.
+All memory used by Lua is subject to automatic management:
+strings, tables, userdata, functions, threads, internal structures, etc.
+
+
+<p>
+An object is considered <em>dead</em>
+as soon as the collector can be sure the object
+will not be accessed again in the normal execution of the program.
+("Normal execution" here excludes finalizers,
+which can resurrect dead objects (see <a href="#2.5.3">&sect;2.5.3</a>),
+and excludes also operations using the debug library.)
+Note that the time when the collector can be sure that an object
+is dead may not coincide with the programmer's expectations.
+The only guarantees are that Lua will not collect an object
+that may still be accessed in the normal execution of the program,
+and it will eventually collect an object
+that is inaccessible from Lua.
+(Here,
+<em>inaccessible from Lua</em> means that neither a variable nor
+another live object refer to the object.)
+Because Lua has no knowledge about C&nbsp;code,
+it never collects objects accessible through the registry (see <a href="#4.3">&sect;4.3</a>),
+which includes the global environment (see <a href="#2.2">&sect;2.2</a>).
+
+
+<p>
+The garbage collector (GC) in Lua can work in two modes:
+incremental and generational.
+
+
+<p>
+The default GC mode with the default parameters
+are adequate for most uses.
+However, programs that waste a large proportion of their time
+allocating and freeing memory can benefit from other settings.
+Keep in mind that the GC behavior is non-portable
+both across platforms and across different Lua releases;
+therefore, optimal settings are also non-portable.
+
+
+<p>
+You can change the GC mode and parameters by calling
+<a href="#lua_gc"><code>lua_gc</code></a> in&nbsp;C
+or <a href="#pdf-collectgarbage"><code>collectgarbage</code></a> in Lua.
+You can also use these functions to control
+the collector directly (e.g., to stop and restart it).
+
+
+
+
+
+<h3>2.5.1 &ndash; <a name="2.5.1">Incremental Garbage Collection</a></h3>
+
+<p>
+In incremental mode,
+each GC cycle performs a mark-and-sweep collection in small steps
+interleaved with the program's execution.
+In this mode,
+the collector uses three numbers to control its garbage-collection cycles:
+the <em>garbage-collector pause</em>,
+the <em>garbage-collector step multiplier</em>,
+and the <em>garbage-collector step size</em>.
+
+
+<p>
+The garbage-collector pause
+controls how long the collector waits before starting a new cycle.
+The collector starts a new cycle when the use of memory
+hits <em>n%</em> of the use after the previous collection.
+Larger values make the collector less aggressive.
+Values equal to or less than 100 mean the collector will not wait to
+start a new cycle.
+A value of 200 means that the collector waits for the total memory in use
+to double before starting a new cycle.
+The default value is 200; the maximum value is 1000.
+
+
+<p>
+The garbage-collector step multiplier
+controls the speed of the collector relative to
+memory allocation,
+that is,
+how many elements it marks or sweeps for each
+kilobyte of memory allocated.
+Larger values make the collector more aggressive but also increase
+the size of each incremental step.
+You should not use values less than 100,
+because they make the collector too slow and
+can result in the collector never finishing a cycle.
+The default value is 100;  the maximum value is 1000.
+
+
+<p>
+The garbage-collector step size controls the
+size of each incremental step,
+specifically how many bytes the interpreter allocates
+before performing a step.
+This parameter is logarithmic:
+A value of <em>n</em> means the interpreter will allocate <em>2<sup>n</sup></em>
+bytes between steps and perform equivalent work during the step.
+A large value (e.g., 60) makes the collector a stop-the-world
+(non-incremental) collector.
+The default value is 13,
+which means steps of approximately 8&nbsp;Kbytes.
+
+
+
+
+
+<h3>2.5.2 &ndash; <a name="2.5.2">Generational Garbage Collection</a></h3>
+
+<p>
+In generational mode,
+the collector does frequent <em>minor</em> collections,
+which traverses only objects recently created.
+If after a minor collection the use of memory is still above a limit,
+the collector does a stop-the-world <em>major</em> collection,
+which traverses all objects.
+The generational mode uses two parameters:
+the <em>minor multiplier</em> and the <em>the major multiplier</em>.
+
+
+<p>
+The minor multiplier controls the frequency of minor collections.
+For a minor multiplier <em>x</em>,
+a new minor collection will be done when memory
+grows <em>x%</em> larger than the memory in use after the previous major
+collection.
+For instance, for a multiplier of 20,
+the collector will do a minor collection when the use of memory
+gets 20% larger than the use after the previous major collection.
+The default value is 20; the maximum value is 200.
+
+
+<p>
+The major multiplier controls the frequency of major collections.
+For a major multiplier <em>x</em>,
+a new major collection will be done when memory
+grows <em>x%</em> larger than the memory in use after the previous major
+collection.
+For instance, for a multiplier of 100,
+the collector will do a major collection when the use of memory
+gets larger than twice the use after the previous collection.
+The default value is 100; the maximum value is 1000.
+
+
+
+
+
+<h3>2.5.3 &ndash; <a name="2.5.3">Garbage-Collection Metamethods</a></h3>
+
+<p>
+You can set garbage-collector metamethods for tables
+and, using the C&nbsp;API,
+for full userdata (see <a href="#2.4">&sect;2.4</a>).
+These metamethods, called <em>finalizers</em>,
+are called when the garbage collector detects that the
+corresponding table or userdata is dead.
+Finalizers allow you to coordinate Lua's garbage collection
+with external resource management such as closing files,
+network or database connections,
+or freeing your own memory.
+
+
+<p>
+For an object (table or userdata) to be finalized when collected,
+you must <em>mark</em> it for finalization.
+
+You mark an object for finalization when you set its metatable
+and the metatable has a <code>__gc</code> metamethod.
+Note that if you set a metatable without a <code>__gc</code> field
+and later create that field in the metatable,
+the object will not be marked for finalization.
+
+
+<p>
+When a marked object becomes dead,
+it is not collected immediately by the garbage collector.
+Instead, Lua puts it in a list.
+After the collection,
+Lua goes through that list.
+For each object in the list,
+it checks the object's <code>__gc</code> metamethod:
+If it is present,
+Lua calls it with the object as its single argument.
+
+
+<p>
+At the end of each garbage-collection cycle,
+the finalizers are called in
+the reverse order that the objects were marked for finalization,
+among those collected in that cycle;
+that is, the first finalizer to be called is the one associated
+with the object marked last in the program.
+The execution of each finalizer may occur at any point during
+the execution of the regular code.
+
+
+<p>
+Because the object being collected must still be used by the finalizer,
+that object (and other objects accessible only through it)
+must be <em>resurrected</em> by Lua.
+Usually, this resurrection is transient,
+and the object memory is freed in the next garbage-collection cycle.
+However, if the finalizer stores the object in some global place
+(e.g., a global variable),
+then the resurrection is permanent.
+Moreover, if the finalizer marks a finalizing object for finalization again,
+its finalizer will be called again in the next cycle where the
+object is dead.
+In any case,
+the object memory is freed only in a GC cycle where
+the object is dead and not marked for finalization.
+
+
+<p>
+When you close a state (see <a href="#lua_close"><code>lua_close</code></a>),
+Lua calls the finalizers of all objects marked for finalization,
+following the reverse order that they were marked.
+If any finalizer marks objects for collection during that phase,
+these marks have no effect.
+
+
+<p>
+Finalizers cannot yield nor run the garbage collector.
+Because they can run in unpredictable times,
+it is good practice to restrict each finalizer
+to the minimum necessary to properly release
+its associated resource.
+
+
+<p>
+Any error while running a finalizer generates a warning;
+the error is not propagated.
+
+
+
+
+
+<h3>2.5.4 &ndash; <a name="2.5.4">Weak Tables</a></h3>
+
+<p>
+A <em>weak table</em> is a table whose elements are
+<em>weak references</em>.
+A weak reference is ignored by the garbage collector.
+In other words,
+if the only references to an object are weak references,
+then the garbage collector will collect that object.
+
+
+<p>
+A weak table can have weak keys, weak values, or both.
+A table with weak values allows the collection of its values,
+but prevents the collection of its keys.
+A table with both weak keys and weak values allows the collection of
+both keys and values.
+In any case, if either the key or the value is collected,
+the whole pair is removed from the table.
+The weakness of a table is controlled by the
+<code>__mode</code> field of its metatable.
+This metavalue, if present, must be one of the following strings:
+"<code>k</code>", for a table with weak keys;
+"<code>v</code>", for a table with weak values;
+or "<code>kv</code>", for a table with both weak keys and values.
+
+
+<p>
+A table with weak keys and strong values
+is also called an <em>ephemeron table</em>.
+In an ephemeron table,
+a value is considered reachable only if its key is reachable.
+In particular,
+if the only reference to a key comes through its value,
+the pair is removed.
+
+
+<p>
+Any change in the weakness of a table may take effect only
+at the next collect cycle.
+In particular, if you change the weakness to a stronger mode,
+Lua may still collect some items from that table
+before the change takes effect.
+
+
+<p>
+Only objects that have an explicit construction
+are removed from weak tables.
+Values, such as numbers and light C&nbsp;functions,
+are not subject to garbage collection,
+and therefore are not removed from weak tables
+(unless their associated values are collected).
+Although strings are subject to garbage collection,
+they do not have an explicit construction and
+their equality is by value;
+they behave more like values than like objects.
+Therefore, they are not removed from weak tables.
+
+
+<p>
+Resurrected objects
+(that is, objects being finalized
+and objects accessible only through objects being finalized)
+have a special behavior in weak tables.
+They are removed from weak values before running their finalizers,
+but are removed from weak keys only in the next collection
+after running their finalizers, when such objects are actually freed.
+This behavior allows the finalizer to access properties
+associated with the object through weak tables.
+
+
+<p>
+If a weak table is among the resurrected objects in a collection cycle,
+it may not be properly cleared until the next cycle.
+
+
+
+
+
+
+
+<h2>2.6 &ndash; <a name="2.6">Coroutines</a></h2>
+
+<p>
+Lua supports coroutines,
+also called <em>collaborative multithreading</em>.
+A coroutine in Lua represents an independent thread of execution.
+Unlike threads in multithread systems, however,
+a coroutine only suspends its execution by explicitly calling
+a yield function.
+
+
+<p>
+You create a coroutine by calling <a href="#pdf-coroutine.create"><code>coroutine.create</code></a>.
+Its sole argument is a function
+that is the main function of the coroutine.
+The <code>create</code> function only creates a new coroutine and
+returns a handle to it (an object of type <em>thread</em>);
+it does not start the coroutine.
+
+
+<p>
+You execute a coroutine by calling <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>.
+When you first call <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>,
+passing as its first argument
+a thread returned by <a href="#pdf-coroutine.create"><code>coroutine.create</code></a>,
+the coroutine starts its execution by
+calling its main function.
+Extra arguments passed to <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> are passed
+as arguments to that function.
+After the coroutine starts running,
+it runs until it terminates or <em>yields</em>.
+
+
+<p>
+A coroutine can terminate its execution in two ways:
+normally, when its main function returns
+(explicitly or implicitly, after the last instruction);
+and abnormally, if there is an unprotected error.
+In case of normal termination,
+<a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> returns <b>true</b>,
+plus any values returned by the coroutine main function.
+In case of errors, <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> returns <b>false</b>
+plus the error object.
+In this case, the coroutine does not unwind its stack,
+so that it is possible to inspect it after the error
+with the debug API.
+
+
+<p>
+A coroutine yields by calling <a href="#pdf-coroutine.yield"><code>coroutine.yield</code></a>.
+When a coroutine yields,
+the corresponding <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> returns immediately,
+even if the yield happens inside nested function calls
+(that is, not in the main function,
+but in a function directly or indirectly called by the main function).
+In the case of a yield, <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> also returns <b>true</b>,
+plus any values passed to <a href="#pdf-coroutine.yield"><code>coroutine.yield</code></a>.
+The next time you resume the same coroutine,
+it continues its execution from the point where it yielded,
+with the call to <a href="#pdf-coroutine.yield"><code>coroutine.yield</code></a> returning any extra
+arguments passed to <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>.
+
+
+<p>
+Like <a href="#pdf-coroutine.create"><code>coroutine.create</code></a>,
+the <a href="#pdf-coroutine.wrap"><code>coroutine.wrap</code></a> function also creates a coroutine,
+but instead of returning the coroutine itself,
+it returns a function that, when called, resumes the coroutine.
+Any arguments passed to this function
+go as extra arguments to <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>.
+<a href="#pdf-coroutine.wrap"><code>coroutine.wrap</code></a> returns all the values returned by <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>,
+except the first one (the boolean error code).
+Unlike <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>,
+the function created by <a href="#pdf-coroutine.wrap"><code>coroutine.wrap</code></a>
+propagates any error to the caller.
+In this case,
+the function also closes the coroutine (see <a href="#pdf-coroutine.close"><code>coroutine.close</code></a>).
+
+
+<p>
+As an example of how coroutines work,
+consider the following code:
+
+<pre>
+     function foo (a)
+       print("foo", a)
+       return coroutine.yield(2*a)
+     end
+     
+     co = coroutine.create(function (a,b)
+           print("co-body", a, b)
+           local r = foo(a+1)
+           print("co-body", r)
+           local r, s = coroutine.yield(a+b, a-b)
+           print("co-body", r, s)
+           return b, "end"
+     end)
+     
+     print("main", coroutine.resume(co, 1, 10))
+     print("main", coroutine.resume(co, "r"))
+     print("main", coroutine.resume(co, "x", "y"))
+     print("main", coroutine.resume(co, "x", "y"))
+</pre><p>
+When you run it, it produces the following output:
+
+<pre>
+     co-body 1       10
+     foo     2
+     main    true    4
+     co-body r
+     main    true    11      -9
+     co-body x       y
+     main    true    10      end
+     main    false   cannot resume dead coroutine
+</pre>
+
+<p>
+You can also create and manipulate coroutines through the C API:
+see functions <a href="#lua_newthread"><code>lua_newthread</code></a>, <a href="#lua_resume"><code>lua_resume</code></a>,
+and <a href="#lua_yield"><code>lua_yield</code></a>.

+<h1>3 &ndash; <a name="3">The Language</a></h1>
+
+
+
+<p>
+This section describes the lexis, the syntax, and the semantics of Lua.
+In other words,
+this section describes
+which tokens are valid,
+how they can be combined,
+and what their combinations mean.
+
+
+<p>
+Language constructs will be explained using the usual extended BNF notation,
+in which
+{<em>a</em>}&nbsp;means&nbsp;0 or more <em>a</em>'s, and
+[<em>a</em>]&nbsp;means an optional <em>a</em>.
+Non-terminals are shown like non-terminal,
+keywords are shown like <b>kword</b>,
+and other terminal symbols are shown like &lsquo;<b>=</b>&rsquo;.
+The complete syntax of Lua can be found in <a href="#9">&sect;9</a>
+at the end of this manual.
+
+
+
+
+
+<h2>3.1 &ndash; <a name="3.1">Lexical Conventions</a></h2>
+
+<p>
+Lua is a free-form language.
+It ignores spaces and comments between lexical elements (tokens),
+except as delimiters between two tokens.
+In source code,
+Lua recognizes as spaces the standard ASCII whitespace
+characters space, form feed, newline,
+carriage return, horizontal tab, and vertical tab.
+
+
+<p>
+<em>Names</em>
+(also called <em>identifiers</em>)
+in Lua can be any string of Latin letters,
+Arabic-Indic digits, and underscores,
+not beginning with a digit and
+not being a reserved word.
+Identifiers are used to name variables, table fields, and labels.
+
+
+<p>
+The following <em>keywords</em> are reserved
+and cannot be used as names:
+
+
+<pre>
+     and       break     do        else      elseif    end
+     false     for       function  goto      if        in
+     local     nil       not       or        repeat    return
+     then      true      until     while
+</pre>
+
+<p>
+Lua is a case-sensitive language:
+<code>and</code> is a reserved word, but <code>And</code> and <code>AND</code>
+are two different, valid names.
+As a convention,
+programs should avoid creating
+names that start with an underscore followed by
+one or more uppercase letters (such as <a href="#pdf-_VERSION"><code>_VERSION</code></a>).
+
+
+<p>
+The following strings denote other tokens:
+
+<pre>
+     +     -     *     /     %     ^     #
+     &amp;     ~     |     &lt;&lt;    &gt;&gt;    //
+     ==    ~=    &lt;=    &gt;=    &lt;     &gt;     =
+     (     )     {     }     [     ]     ::
+     ;     :     ,     .     ..    ...
+</pre>
+
+<p>
+A <em>short literal string</em>
+can be delimited by matching single or double quotes,
+and can contain the following C-like escape sequences:
+'<code>\a</code>' (bell),
+'<code>\b</code>' (backspace),
+'<code>\f</code>' (form feed),
+'<code>\n</code>' (newline),
+'<code>\r</code>' (carriage return),
+'<code>\t</code>' (horizontal tab),
+'<code>\v</code>' (vertical tab),
+'<code>\\</code>' (backslash),
+'<code>\"</code>' (quotation mark [double quote]),
+and '<code>\'</code>' (apostrophe [single quote]).
+A backslash followed by a line break
+results in a newline in the string.
+The escape sequence '<code>\z</code>' skips the following span
+of whitespace characters,
+including line breaks;
+it is particularly useful to break and indent a long literal string
+into multiple lines without adding the newlines and spaces
+into the string contents.
+A short literal string cannot contain unescaped line breaks
+nor escapes not forming a valid escape sequence.
+
+
+<p>
+We can specify any byte in a short literal string,
+including embedded zeros,
+by its numeric value.
+This can be done
+with the escape sequence <code>\x<em>XX</em></code>,
+where <em>XX</em> is a sequence of exactly two hexadecimal digits,
+or with the escape sequence <code>\<em>ddd</em></code>,
+where <em>ddd</em> is a sequence of up to three decimal digits.
+(Note that if a decimal escape sequence is to be followed by a digit,
+it must be expressed using exactly three digits.)
+
+
+<p>
+The UTF-8 encoding of a Unicode character
+can be inserted in a literal string with
+the escape sequence <code>\u{<em>XXX</em>}</code>
+(with mandatory enclosing braces),
+where <em>XXX</em> is a sequence of one or more hexadecimal digits
+representing the character code point.
+This code point can be any value less than <em>2<sup>31</sup></em>.
+(Lua uses the original UTF-8 specification here,
+which is not restricted to valid Unicode code points.)
+
+
+<p>
+Literal strings can also be defined using a long format
+enclosed by <em>long brackets</em>.
+We define an <em>opening long bracket of level <em>n</em></em> as an opening
+square bracket followed by <em>n</em> equal signs followed by another
+opening square bracket.
+So, an opening long bracket of level&nbsp;0 is written as <code>[[</code>, 
+an opening long bracket of level&nbsp;1 is written as <code>[=[</code>, 
+and so on.
+A <em>closing long bracket</em> is defined similarly;
+for instance,
+a closing long bracket of level&nbsp;4 is written as  <code>]====]</code>.
+A <em>long literal</em> starts with an opening long bracket of any level and
+ends at the first closing long bracket of the same level.
+It can contain any text except a closing bracket of the same level.
+Literals in this bracketed form can run for several lines,
+do not interpret any escape sequences,
+and ignore long brackets of any other level.
+Any kind of end-of-line sequence
+(carriage return, newline, carriage return followed by newline,
+or newline followed by carriage return)
+is converted to a simple newline.
+When the opening long bracket is immediately followed by a newline,
+the newline is not included in the string.
+
+
+<p>
+As an example, in a system using ASCII
+(in which '<code>a</code>' is coded as&nbsp;97,
+newline is coded as&nbsp;10, and '<code>1</code>' is coded as&nbsp;49),
+the five literal strings below denote the same string:
+
+<pre>
+     a = 'alo\n123"'
+     a = "alo\n123\""
+     a = '\97lo\10\04923"'
+     a = [[alo
+     123"]]
+     a = [==[
+     alo
+     123"]==]
+</pre>
+
+<p>
+Any byte in a literal string not
+explicitly affected by the previous rules represents itself.
+However, Lua opens files for parsing in text mode,
+and the system's file functions may have problems with
+some control characters.
+So, it is safer to represent
+binary data as a quoted literal with
+explicit escape sequences for the non-text characters.
+
+
+<p>
+A <em>numeric constant</em> (or <em>numeral</em>)
+can be written with an optional fractional part
+and an optional decimal exponent,
+marked by a letter '<code>e</code>' or '<code>E</code>'.
+Lua also accepts hexadecimal constants,
+which start with <code>0x</code> or <code>0X</code>.
+Hexadecimal constants also accept an optional fractional part
+plus an optional binary exponent,
+marked by a letter '<code>p</code>' or '<code>P</code>' and written in decimal.
+(For instance, <code>0x1.fp10</code> denotes 1984,
+which is <em>0x1f / 16</em> multiplied by <em>2<sup>10</sup></em>.)
+
+
+<p>
+A numeric constant with a radix point or an exponent
+denotes a float;
+otherwise,
+if its value fits in an integer or it is a hexadecimal constant,
+it denotes an integer;
+otherwise (that is, a decimal integer numeral that overflows),
+it denotes a float.
+Hexadecimal numerals with neither a radix point nor an exponent
+always denote an integer value;
+if the value overflows, it <em>wraps around</em>
+to fit into a valid integer.
+
+
+<p>
+Examples of valid integer constants are
+
+<pre>
+     3   345   0xff   0xBEBADA
+</pre><p>
+Examples of valid float constants are
+
+<pre>
+     3.0     3.1416     314.16e-2     0.31416E1     34e1
+     0x0.1E  0xA23p-4   0X1.921FB54442D18P+1
+</pre>
+
+<p>
+A <em>comment</em> starts with a double hyphen (<code>--</code>)
+anywhere outside a string.
+If the text immediately after <code>--</code> is not an opening long bracket,
+the comment is a <em>short comment</em>,
+which runs until the end of the line.
+Otherwise, it is a <em>long comment</em>,
+which runs until the corresponding closing long bracket.
+
+
+
+
+
+<h2>3.2 &ndash; <a name="3.2">Variables</a></h2>
+
+<p>
+Variables are places that store values.
+There are three kinds of variables in Lua:
+global variables, local variables, and table fields.
+
+
+<p>
+A single name can denote a global variable or a local variable
+(or a function's formal parameter,
+which is a particular kind of local variable):
+
+<pre>
+	var ::= Name
+</pre><p>
+Name denotes identifiers (see <a href="#3.1">&sect;3.1</a>).
+
+
+<p>
+Any variable name is assumed to be global unless explicitly declared
+as a local (see <a href="#3.3.7">&sect;3.3.7</a>).
+Local variables are <em>lexically scoped</em>:
+local variables can be freely accessed by functions
+defined inside their scope (see <a href="#3.5">&sect;3.5</a>).
+
+
+<p>
+Before the first assignment to a variable, its value is <b>nil</b>.
+
+
+<p>
+Square brackets are used to index a table:
+
+<pre>
+	var ::= prefixexp &lsquo;<b>[</b>&rsquo; exp &lsquo;<b>]</b>&rsquo;
+</pre><p>
+The meaning of accesses to table fields can be changed via metatables
+(see <a href="#2.4">&sect;2.4</a>).
+
+
+<p>
+The syntax <code>var.Name</code> is just syntactic sugar for
+<code>var["Name"]</code>:
+
+<pre>
+	var ::= prefixexp &lsquo;<b>.</b>&rsquo; Name
+</pre>
+
+<p>
+An access to a global variable <code>x</code>
+is equivalent to <code>_ENV.x</code>.
+Due to the way that chunks are compiled,
+the variable <code>_ENV</code> itself is never global (see <a href="#2.2">&sect;2.2</a>).
+
+
+
+
+
+<h2>3.3 &ndash; <a name="3.3">Statements</a></h2>
+
+
+
+<p>
+Lua supports an almost conventional set of statements,
+similar to those in other conventional languages.
+This set includes
+blocks, assignments, control structures, function calls,
+and variable declarations.
+
+
+
+
+
+<h3>3.3.1 &ndash; <a name="3.3.1">Blocks</a></h3>
+
+<p>
+A block is a list of statements,
+which are executed sequentially:
+
+<pre>
+	block ::= {stat}
+</pre><p>
+Lua has <em>empty statements</em>
+that allow you to separate statements with semicolons,
+start a block with a semicolon
+or write two semicolons in sequence:
+
+<pre>
+	stat ::= &lsquo;<b>;</b>&rsquo;
+</pre>
+
+<p>
+Both function calls and assignments
+can start with an open parenthesis.
+This possibility leads to an ambiguity in Lua's grammar.
+Consider the following fragment:
+
+<pre>
+     a = b + c
+     (print or io.write)('done')
+</pre><p>
+The grammar could see this fragment in two ways:
+
+<pre>
+     a = b + c(print or io.write)('done')
+     
+     a = b + c; (print or io.write)('done')
+</pre><p>
+The current parser always sees such constructions
+in the first way,
+interpreting the open parenthesis
+as the start of the arguments to a call.
+To avoid this ambiguity,
+it is a good practice to always precede with a semicolon
+statements that start with a parenthesis:
+
+<pre>
+     ;(print or io.write)('done')
+</pre>
+
+<p>
+A block can be explicitly delimited to produce a single statement:
+
+<pre>
+	stat ::= <b>do</b> block <b>end</b>
+</pre><p>
+Explicit blocks are useful
+to control the scope of variable declarations.
+Explicit blocks are also sometimes used to
+add a <b>return</b> statement in the middle
+of another block (see <a href="#3.3.4">&sect;3.3.4</a>).
+
+
+
+
+
+<h3>3.3.2 &ndash; <a name="3.3.2">Chunks</a></h3>
+
+<p>
+The unit of compilation of Lua is called a <em>chunk</em>.
+Syntactically,
+a chunk is simply a block:
+
+<pre>
+	chunk ::= block
+</pre>
+
+<p>
+Lua handles a chunk as the body of an anonymous function
+with a variable number of arguments
+(see <a href="#3.4.11">&sect;3.4.11</a>).
+As such, chunks can define local variables,
+receive arguments, and return values.
+Moreover, such anonymous function is compiled as in the
+scope of an external local variable called <code>_ENV</code> (see <a href="#2.2">&sect;2.2</a>).
+The resulting function always has <code>_ENV</code> as its only external variable,
+even if it does not use that variable.
+
+
+<p>
+A chunk can be stored in a file or in a string inside the host program.
+To execute a chunk,
+Lua first <em>loads</em> it,
+precompiling the chunk's code into instructions for a virtual machine,
+and then Lua executes the compiled code
+with an interpreter for the virtual machine.
+
+
+<p>
+Chunks can also be precompiled into binary form;
+see the program <code>luac</code> and the function <a href="#pdf-string.dump"><code>string.dump</code></a> for details.
+Programs in source and compiled forms are interchangeable;
+Lua automatically detects the file type and acts accordingly (see <a href="#pdf-load"><code>load</code></a>).
+
+
+
+
+
+<h3>3.3.3 &ndash; <a name="3.3.3">Assignment</a></h3>
+
+<p>
+Lua allows multiple assignments.
+Therefore, the syntax for assignment
+defines a list of variables on the left side
+and a list of expressions on the right side.
+The elements in both lists are separated by commas:
+
+<pre>
+	stat ::= varlist &lsquo;<b>=</b>&rsquo; explist
+	varlist ::= var {&lsquo;<b>,</b>&rsquo; var}
+	explist ::= exp {&lsquo;<b>,</b>&rsquo; exp}
+</pre><p>
+Expressions are discussed in <a href="#3.4">&sect;3.4</a>.
+
+
+<p>
+Before the assignment,
+the list of values is <em>adjusted</em> to the length of
+the list of variables (see <a href="#3.4.12">&sect;3.4.12</a>).
+
+
+<p>
+If a variable is both assigned and read
+inside a multiple assignment,
+Lua ensures that all reads get the value of the variable
+before the assignment.
+Thus the code
+
+<pre>
+     i = 3
+     i, a[i] = i+1, 20
+</pre><p>
+sets <code>a[3]</code> to 20, without affecting <code>a[4]</code>
+because the <code>i</code> in <code>a[i]</code> is evaluated (to 3)
+before it is assigned&nbsp;4.
+Similarly, the line
+
+<pre>
+     x, y = y, x
+</pre><p>
+exchanges the values of <code>x</code> and <code>y</code>,
+and
+
+<pre>
+     x, y, z = y, z, x
+</pre><p>
+cyclically permutes the values of <code>x</code>, <code>y</code>, and <code>z</code>.
+
+
+<p>
+Note that this guarantee covers only accesses
+syntactically inside the assignment statement.
+If a function or a metamethod called during the assignment
+changes the value of a variable,
+Lua gives no guarantees about the order of that access.
+
+
+<p>
+An assignment to a global name <code>x = val</code>
+is equivalent to the assignment
+<code>_ENV.x = val</code> (see <a href="#2.2">&sect;2.2</a>).
+
+
+<p>
+The meaning of assignments to table fields and
+global variables (which are actually table fields, too)
+can be changed via metatables (see <a href="#2.4">&sect;2.4</a>).
+
+
+
+
+
+<h3>3.3.4 &ndash; <a name="3.3.4">Control Structures</a></h3><p>
+The control structures
+<b>if</b>, <b>while</b>, and <b>repeat</b> have the usual meaning and
+familiar syntax:
+
+
+
+
+<pre>
+	stat ::= <b>while</b> exp <b>do</b> block <b>end</b>
+	stat ::= <b>repeat</b> block <b>until</b> exp
+	stat ::= <b>if</b> exp <b>then</b> block {<b>elseif</b> exp <b>then</b> block} [<b>else</b> block] <b>end</b>
+</pre><p>
+Lua also has a <b>for</b> statement, in two flavors (see <a href="#3.3.5">&sect;3.3.5</a>).
+
+
+<p>
+The condition expression of a
+control structure can return any value.
+Both <b>false</b> and <b>nil</b> test false.
+All values different from <b>nil</b> and <b>false</b> test true.
+In particular, the number 0 and the empty string also test true.
+
+
+<p>
+In the <b>repeat</b>&ndash;<b>until</b> loop,
+the inner block does not end at the <b>until</b> keyword,
+but only after the condition.
+So, the condition can refer to local variables
+declared inside the loop block.
+
+
+<p>
+The <b>goto</b> statement transfers the program control to a label.
+For syntactical reasons,
+labels in Lua are considered statements too:
+
+
+
+<pre>
+	stat ::= <b>goto</b> Name
+	stat ::= label
+	label ::= &lsquo;<b>::</b>&rsquo; Name &lsquo;<b>::</b>&rsquo;
+</pre>
+
+<p>
+A label is visible in the entire block where it is defined,
+except inside nested functions.
+A goto may jump to any visible label as long as it does not
+enter into the scope of a local variable.
+A label should not be declared
+where a label with the same name is visible,
+even if this other label has been declared in an enclosing block.
+
+
+<p>
+The <b>break</b> statement terminates the execution of a
+<b>while</b>, <b>repeat</b>, or <b>for</b> loop,
+skipping to the next statement after the loop:
+
+
+<pre>
+	stat ::= <b>break</b>
+</pre><p>
+A <b>break</b> ends the innermost enclosing loop.
+
+
+<p>
+The <b>return</b> statement is used to return values
+from a function or a chunk
+(which is handled as an anonymous function).
+
+Functions can return more than one value,
+so the syntax for the <b>return</b> statement is
+
+<pre>
+	stat ::= <b>return</b> [explist] [&lsquo;<b>;</b>&rsquo;]
+</pre>
+
+<p>
+The <b>return</b> statement can only be written
+as the last statement of a block.
+If it is necessary to <b>return</b> in the middle of a block,
+then an explicit inner block can be used,
+as in the idiom <code>do return end</code>,
+because now <b>return</b> is the last statement in its (inner) block.
+
+
+
+
+
+<h3>3.3.5 &ndash; <a name="3.3.5">For Statement</a></h3>
+
+<p>
+
+The <b>for</b> statement has two forms:
+one numerical and one generic.
+
+
+
+<h4>The numerical <b>for</b> loop</h4>
+
+<p>
+The numerical <b>for</b> loop repeats a block of code while a
+control variable goes through an arithmetic progression.
+It has the following syntax:
+
+<pre>
+	stat ::= <b>for</b> Name &lsquo;<b>=</b>&rsquo; exp &lsquo;<b>,</b>&rsquo; exp [&lsquo;<b>,</b>&rsquo; exp] <b>do</b> block <b>end</b>
+</pre><p>
+The given identifier (Name) defines the control variable,
+which is a new variable local to the loop body (<em>block</em>).
+
+
+<p>
+The loop starts by evaluating once the three control expressions.
+Their values are called respectively
+the <em>initial value</em>, the <em>limit</em>, and the <em>step</em>.
+If the step is absent, it defaults to&nbsp;1.
+
+
+<p>
+If both the initial value and the step are integers,
+the loop is done with integers;
+note that the limit may not be an integer.
+Otherwise, the three values are converted to
+floats and the loop is done with floats.
+Beware of floating-point accuracy in this case.
+
+
+<p>
+After that initialization,
+the loop body is repeated with the value of the control variable
+going through an arithmetic progression,
+starting at the initial value,
+with a common difference given by the step.
+A negative step makes a decreasing sequence;
+a step equal to zero raises an error.
+The loop continues while the value is less than
+or equal to the limit
+(greater than or equal to for a negative step).
+If the initial value is already greater than the limit
+(or less than, if the step is negative),
+the body is not executed.
+
+
+<p>
+For integer loops,
+the control variable never wraps around;
+instead, the loop ends in case of an overflow.
+
+
+<p>
+You should not change the value of the control variable
+during the loop.
+If you need its value after the loop,
+assign it to another variable before exiting the loop.
+
+
+
+
+
+<h4>The generic <b>for</b> loop</h4>
+
+<p>
+The generic <b>for</b> statement works over functions,
+called <em>iterators</em>.
+On each iteration, the iterator function is called to produce a new value,
+stopping when this new value is <b>nil</b>.
+The generic <b>for</b> loop has the following syntax:
+
+<pre>
+	stat ::= <b>for</b> namelist <b>in</b> explist <b>do</b> block <b>end</b>
+	namelist ::= Name {&lsquo;<b>,</b>&rsquo; Name}
+</pre><p>
+A <b>for</b> statement like
+
+<pre>
+     for <em>var_1</em>, &middot;&middot;&middot;, <em>var_n</em> in <em>explist</em> do <em>body</em> end
+</pre><p>
+works as follows.
+
+
+<p>
+The names <em>var_i</em> declare loop variables local to the loop body.
+The first of these variables is the <em>control variable</em>.
+
+
+<p>
+The loop starts by evaluating <em>explist</em>
+to produce four values:
+an <em>iterator function</em>,
+a <em>state</em>,
+an initial value for the control variable,
+and a <em>closing value</em>.
+
+
+<p>
+Then, at each iteration,
+Lua calls the iterator function with two arguments:
+the state and the control variable.
+The results from this call are then assigned to the loop variables,
+following the rules of multiple assignments (see <a href="#3.3.3">&sect;3.3.3</a>).
+If the control variable becomes <b>nil</b>,
+the loop terminates.
+Otherwise, the body is executed and the loop goes
+to the next iteration.
+
+
+<p>
+The closing value behaves like a
+to-be-closed variable (see <a href="#3.3.8">&sect;3.3.8</a>),
+which can be used to release resources when the loop ends.
+Otherwise, it does not interfere with the loop.
+
+
+<p>
+You should not change the value of the control variable
+during the loop.
+
+
+
+
+
+
+
+<h3>3.3.6 &ndash; <a name="3.3.6">Function Calls as Statements</a></h3><p>
+To allow possible side-effects,
+function calls can be executed as statements:
+
+<pre>
+	stat ::= functioncall
+</pre><p>
+In this case, all returned values are thrown away.
+Function calls are explained in <a href="#3.4.10">&sect;3.4.10</a>.
+
+
+
+
+
+<h3>3.3.7 &ndash; <a name="3.3.7">Local Declarations</a></h3><p>
+Local variables can be declared anywhere inside a block.
+The declaration can include an initialization:
+
+<pre>
+	stat ::= <b>local</b> attnamelist [&lsquo;<b>=</b>&rsquo; explist]
+	attnamelist ::=  Name attrib {&lsquo;<b>,</b>&rsquo; Name attrib}
+</pre><p>
+If present, an initial assignment has the same semantics
+of a multiple assignment (see <a href="#3.3.3">&sect;3.3.3</a>).
+Otherwise, all variables are initialized with <b>nil</b>.
+
+
+<p>
+Each variable name may be postfixed by an attribute
+(a name between angle brackets):
+
+<pre>
+	attrib ::= [&lsquo;<b>&lt;</b>&rsquo; Name &lsquo;<b>&gt;</b>&rsquo;]
+</pre><p>
+There are two possible attributes:
+<code>const</code>, which declares a constant variable,
+that is, a variable that cannot be assigned to
+after its initialization;
+and <code>close</code>, which declares a to-be-closed variable (see <a href="#3.3.8">&sect;3.3.8</a>).
+A list of variables can contain at most one to-be-closed variable.
+
+
+<p>
+A chunk is also a block (see <a href="#3.3.2">&sect;3.3.2</a>),
+and so local variables can be declared in a chunk outside any explicit block.
+
+
+<p>
+The visibility rules for local variables are explained in <a href="#3.5">&sect;3.5</a>.
+
+
+
+
+
+<h3>3.3.8 &ndash; <a name="3.3.8">To-be-closed Variables</a></h3>
+
+<p>
+A to-be-closed variable behaves like a constant local variable,
+except that its value is <em>closed</em> whenever the variable
+goes out of scope, including normal block termination,
+exiting its block by <b>break</b>/<b>goto</b>/<b>return</b>,
+or exiting by an error.
+
+
+<p>
+Here, to <em>close</em> a value means
+to call its <code>__close</code> metamethod.
+When calling the metamethod,
+the value itself is passed as the first argument
+and the error object that caused the exit (if any)
+is passed as a second argument;
+if there was no error, the second argument is <b>nil</b>.
+
+
+<p>
+The value assigned to a to-be-closed variable
+must have a <code>__close</code> metamethod
+or be a false value.
+(<b>nil</b> and <b>false</b> are ignored as to-be-closed values.)
+
+
+<p>
+If several to-be-closed variables go out of scope at the same event,
+they are closed in the reverse order that they were declared.
+
+
+<p>
+If there is any error while running a closing method,
+that error is handled like an error in the regular code
+where the variable was defined.
+After an error,
+the other pending closing methods will still be called.
+
+
+<p>
+If a coroutine yields and is never resumed again,
+some variables may never go out of scope,
+and therefore they will never be closed.
+(These variables are the ones created inside the coroutine
+and in scope at the point where the coroutine yielded.)
+Similarly, if a coroutine ends with an error,
+it does not unwind its stack,
+so it does not close any variable.
+In both cases,
+you can either use finalizers
+or call <a href="#pdf-coroutine.close"><code>coroutine.close</code></a> to close the variables.
+However, if the coroutine was created
+through <a href="#pdf-coroutine.wrap"><code>coroutine.wrap</code></a>,
+then its corresponding function will close the coroutine
+in case of errors.
+
+

+	exp ::= <b>nil</b> | <b>false</b> | <b>true</b>
+	exp ::= Numeral
+	exp ::= LiteralString
+	exp ::= functiondef

+Numerals and literal strings are explained in <a href="#3.1">&sect;3.1</a>;
+variables are explained in <a href="#3.2">&sect;3.2</a>;
+function definitions are explained in <a href="#3.4.11">&sect;3.4.11</a>;
+function calls are explained in <a href="#3.4.10">&sect;3.4.10</a>;
+table constructors are explained in <a href="#3.4.9">&sect;3.4.9</a>.
+Vararg expressions,
+denoted by three dots ('<code>...</code>'), can only be used when
+directly inside a variadic function;
+they are explained in <a href="#3.4.11">&sect;3.4.11</a>.
+
+
+<p>
+Binary operators comprise arithmetic operators (see <a href="#3.4.1">&sect;3.4.1</a>),
+bitwise operators (see <a href="#3.4.2">&sect;3.4.2</a>),
+relational operators (see <a href="#3.4.4">&sect;3.4.4</a>), logical operators (see <a href="#3.4.5">&sect;3.4.5</a>),
+and the concatenation operator (see <a href="#3.4.6">&sect;3.4.6</a>).
+Unary operators comprise the unary minus (see <a href="#3.4.1">&sect;3.4.1</a>),
+the unary bitwise NOT (see <a href="#3.4.2">&sect;3.4.2</a>),
+the unary logical <b>not</b> (see <a href="#3.4.5">&sect;3.4.5</a>),
+and the unary <em>length operator</em> (see <a href="#3.4.7">&sect;3.4.7</a>).
+
+
+
+
+
+<h3>3.4.1 &ndash; <a name="3.4.1">Arithmetic Operators</a></h3><p>
+Lua supports the following arithmetic operators:
+
+<ul>
+<li><b><code>+</code>: </b>addition</li>
+<li><b><code>-</code>: </b>subtraction</li>
+<li><b><code>*</code>: </b>multiplication</li>
+<li><b><code>/</code>: </b>float division</li>
+<li><b><code>//</code>: </b>floor division</li>
+<li><b><code>%</code>: </b>modulo</li>
+<li><b><code>^</code>: </b>exponentiation</li>
+<li><b><code>-</code>: </b>unary minus</li>
+</ul>
+
+<p>
+With the exception of exponentiation and float division,
+the arithmetic operators work as follows:
+If both operands are integers,
+the operation is performed over integers and the result is an integer.
+Otherwise, if both operands are numbers,
+then they are converted to floats,
+the operation is performed following the machine's rules
+for floating-point arithmetic
+(usually the IEEE 754 standard),
+and the result is a float.
+(The string library coerces strings to numbers in
+arithmetic operations; see <a href="#3.4.3">&sect;3.4.3</a> for details.)
+
+
+<p>
+Exponentiation and float division (<code>/</code>)
+always convert their operands to floats
+and the result is always a float.
+Exponentiation uses the ISO&nbsp;C function <code>pow</code>,
+so that it works for non-integer exponents too.
+
+
+<p>
+Floor division (<code>//</code>) is a division
+that rounds the quotient towards minus infinity,
+resulting in the floor of the division of its operands.
+
+
+<p>
+Modulo is defined as the remainder of a division
+that rounds the quotient towards minus infinity (floor division).
+
+
+<p>
+In case of overflows in integer arithmetic,
+all operations <em>wrap around</em>.
+
+
+
+<h3>3.4.2 &ndash; <a name="3.4.2">Bitwise Operators</a></h3><p>
+Lua supports the following bitwise operators:
+
+<ul>
+<li><b><code>&amp;</code>: </b>bitwise AND</li>
+<li><b><code>&#124;</code>: </b>bitwise OR</li>
+<li><b><code>~</code>: </b>bitwise exclusive OR</li>
+<li><b><code>&gt;&gt;</code>: </b>right shift</li>
+<li><b><code>&lt;&lt;</code>: </b>left shift</li>
+<li><b><code>~</code>: </b>unary bitwise NOT</li>
+</ul>
+
+<p>
+All bitwise operations convert its operands to integers
+(see <a href="#3.4.3">&sect;3.4.3</a>),
+operate on all bits of those integers,
+and result in an integer.
+
+
+<p>
+Both right and left shifts fill the vacant bits with zeros.
+Negative displacements shift to the other direction;
+displacements with absolute values equal to or higher than
+the number of bits in an integer
+result in zero (as all bits are shifted out).
+
+
+
+
+
+<h3>3.4.3 &ndash; <a name="3.4.3">Coercions and Conversions</a></h3><p>
+Lua provides some automatic conversions between some
+types and representations at run time.
+Bitwise operators always convert float operands to integers.
+Exponentiation and float division
+always convert integer operands to floats.
+All other arithmetic operations applied to mixed numbers
+(integers and floats) convert the integer operand to a float.
+The C API also converts both integers to floats and
+floats to integers, as needed.
+Moreover, string concatenation accepts numbers as arguments,
+besides strings.
+
+
+<p>
+In a conversion from integer to float,
+if the integer value has an exact representation as a float,
+that is the result.
+Otherwise,
+the conversion gets the nearest higher or
+the nearest lower representable value.
+This kind of conversion never fails.
+
+
+<p>
+The conversion from float to integer
+checks whether the float has an exact representation as an integer
+(that is, the float has an integral value and
+it is in the range of integer representation).
+If it does, that representation is the result.
+Otherwise, the conversion fails.
+
+
+<p>
+Several places in Lua coerce strings to numbers when necessary.
+In particular,
+the string library sets metamethods that try to coerce
+strings to numbers in all arithmetic operations.
+If the conversion fails,
+the library calls the metamethod of the other operand
+(if present) or it raises an error.
+Note that bitwise operators do not do this coercion.
+
+
+<p>
+It is always a good practice not to rely on the
+implicit coercions from strings to numbers,
+as they are not always applied;
+in particular, <code>"1"==1</code> is false and <code>"1"&lt;1</code> raises an error
+(see <a href="#3.4.4">&sect;3.4.4</a>).
+These coercions exist mainly for compatibility and may be removed
+in future versions of the language.
+
+
+<p>
+A string is converted to an integer or a float
+following its syntax and the rules of the Lua lexer.
+The string may have also leading and trailing whitespaces and a sign.
+All conversions from strings to numbers
+accept both a dot and the current locale mark
+as the radix character.
+(The Lua lexer, however, accepts only a dot.)
+If the string is not a valid numeral,
+the conversion fails.
+If necessary, the result of this first step is then converted
+to a specific number subtype following the previous rules
+for conversions between floats and integers.
+
+
+<p>
+The conversion from numbers to strings uses a
+non-specified human-readable format.
+To convert numbers to strings in any specific way,
+use the function <a href="#pdf-string.format"><code>string.format</code></a>.
+
+
+
+
+
+<h3>3.4.4 &ndash; <a name="3.4.4">Relational Operators</a></h3><p>
+Lua supports the following relational operators:
+
+<ul>
+<li><b><code>==</code>: </b>equality</li>
+<li><b><code>~=</code>: </b>inequality</li>
+<li><b><code>&lt;</code>: </b>less than</li>
+<li><b><code>&gt;</code>: </b>greater than</li>
+<li><b><code>&lt;=</code>: </b>less or equal</li>
+<li><b><code>&gt;=</code>: </b>greater or equal</li>
+</ul><p>
+These operators always result in <b>false</b> or <b>true</b>.
+
+
+<p>
+Equality (<code>==</code>) first compares the type of its operands.
+If the types are different, then the result is <b>false</b>.
+Otherwise, the values of the operands are compared.
+Strings are equal if they have the same byte content.
+Numbers are equal if they denote the same mathematical value.
+
+
+<p>
+Tables, userdata, and threads
+are compared by reference:
+two objects are considered equal only if they are the same object.
+Every time you create a new object
+(a table, a userdata, or a thread),
+this new object is different from any previously existing object.
+A function is always equal to itself.
+Functions with any detectable difference
+(different behavior, different definition) are always different.
+Functions created at different times but with no detectable differences
+may be classified as equal or not
+(depending on internal caching details).
+
+
+<p>
+You can change the way that Lua compares tables and userdata
+by using the <code>__eq</code> metamethod (see <a href="#2.4">&sect;2.4</a>).
+
+
+<p>
+Equality comparisons do not convert strings to numbers
+or vice versa.
+Thus, <code>"0"==0</code> evaluates to <b>false</b>,
+and <code>t[0]</code> and <code>t["0"]</code> denote different
+entries in a table.
+
+
+<p>
+The operator <code>~=</code> is exactly the negation of equality (<code>==</code>).
+
+
+<p>
+The order operators work as follows.
+If both arguments are numbers,
+then they are compared according to their mathematical values,
+regardless of their subtypes.
+Otherwise, if both arguments are strings,
+then their values are compared according to the current locale.
+Otherwise, Lua tries to call the <code>__lt</code> or the <code>__le</code>
+metamethod (see <a href="#2.4">&sect;2.4</a>).
+A comparison <code>a &gt; b</code> is translated to <code>b &lt; a</code>
+and <code>a &gt;= b</code> is translated to <code>b &lt;= a</code>.
+
+
+<p>
+Following the IEEE 754 standard,
+the special value NaN is considered neither less than,
+nor equal to, nor greater than any value, including itself.
+
+
+
+
+
+<h3>3.4.5 &ndash; <a name="3.4.5">Logical Operators</a></h3><p>
+The logical operators in Lua are
+<b>and</b>, <b>or</b>, and <b>not</b>.
+Like the control structures (see <a href="#3.3.4">&sect;3.3.4</a>),
+all logical operators consider both <b>false</b> and <b>nil</b> as false
+and anything else as true.
+
+
+<p>
+The negation operator <b>not</b> always returns <b>false</b> or <b>true</b>.
+The conjunction operator <b>and</b> returns its first argument
+if this value is <b>false</b> or <b>nil</b>;
+otherwise, <b>and</b> returns its second argument.
+The disjunction operator <b>or</b> returns its first argument
+if this value is different from <b>nil</b> and <b>false</b>;
+otherwise, <b>or</b> returns its second argument.
+Both <b>and</b> and <b>or</b> use short-circuit evaluation;
+that is,
+the second operand is evaluated only if necessary.
+Here are some examples:
+
+<pre>
+     10 or 20            --&gt; 10
+     10 or error()       --&gt; 10
+     nil or "a"          --&gt; "a"
+     nil and 10          --&gt; nil
+     false and error()   --&gt; false
+     false and nil       --&gt; false
+     false or nil        --&gt; nil
+     10 and 20           --&gt; 20
+</pre>
+
+
+
+
+<h3>3.4.6 &ndash; <a name="3.4.6">Concatenation</a></h3><p>
+The string concatenation operator in Lua is
+denoted by two dots ('<code>..</code>').
+If both operands are strings or numbers,
+then the numbers are converted to strings
+in a non-specified format (see <a href="#3.4.3">&sect;3.4.3</a>).
+Otherwise, the <code>__concat</code> metamethod is called (see <a href="#2.4">&sect;2.4</a>).
+
+
+
+
+
+<h3>3.4.7 &ndash; <a name="3.4.7">The Length Operator</a></h3>
+
+<p>
+The length operator is denoted by the unary prefix operator <code>#</code>.
+
+
+<p>
+The length of a string is its number of bytes.
+(That is the usual meaning of string length when each
+character is one byte.)
+
+
+<p>
+The length operator applied on a table
+returns a border in that table.
+A <em>border</em> in a table <code>t</code> is any non-negative integer
+that satisfies the following condition:
+
+<pre>
+     (border == 0 or t[border] ~= nil) and
+     (t[border + 1] == nil or border == math.maxinteger)
+</pre><p>
+In words,
+a border is any positive integer index present in the table
+that is followed by an absent index,
+plus two limit cases:
+zero, when index 1 is absent;
+and the maximum value for an integer, when that index is present.
+Note that keys that are not positive integers
+do not interfere with borders.
+
+
+<p>
+A table with exactly one border is called a <em>sequence</em>.
+For instance, the table <code>{10, 20, 30, 40, 50}</code> is a sequence,
+as it has only one border (5).
+The table <code>{10, 20, 30, nil, 50}</code> has two borders (3 and 5),
+and therefore it is not a sequence.
+(The <b>nil</b> at index 4 is called a <em>hole</em>.)
+The table <code>{nil, 20, 30, nil, nil, 60, nil}</code>
+has three borders (0, 3, and 6),
+so it is not a sequence, too.
+The table <code>{}</code> is a sequence with border 0.
+
+
+<p>
+When <code>t</code> is a sequence,
+<code>#t</code> returns its only border,
+which corresponds to the intuitive notion of the length of the sequence.
+When <code>t</code> is not a sequence,
+<code>#t</code> can return any of its borders.
+(The exact one depends on details of
+the internal representation of the table,
+which in turn can depend on how the table was populated and
+the memory addresses of its non-numeric keys.)
+
+
+<p>
+The computation of the length of a table
+has a guaranteed worst time of <em>O(log n)</em>,
+where <em>n</em> is the largest integer key in the table.
+
+
+<p>
+A program can modify the behavior of the length operator for
+any value but strings through the <code>__len</code> metamethod (see <a href="#2.4">&sect;2.4</a>).
+
+
+
+
+
+<h3>3.4.8 &ndash; <a name="3.4.8">Precedence</a></h3><p>
+Operator precedence in Lua follows the table below,
+from lower to higher priority:
+
+<pre>
+     or
+     and
+     &lt;     &gt;     &lt;=    &gt;=    ~=    ==
+     |
+     ~
+     &amp;
+     &lt;&lt;    &gt;&gt;
+     ..
+     +     -
+     *     /     //    %
+     unary operators (not   #     -     ~)
+     ^
+</pre><p>
+As usual,
+you can use parentheses to change the precedences of an expression.
+The concatenation ('<code>..</code>') and exponentiation ('<code>^</code>')
+operators are right associative.
+All other binary operators are left associative.
+
+
+
+
+
+<h3>3.4.9 &ndash; <a name="3.4.9">Table Constructors</a></h3><p>
+Table constructors are expressions that create tables.
+Every time a constructor is evaluated, a new table is created.
+A constructor can be used to create an empty table
+or to create a table and initialize some of its fields.
+The general syntax for constructors is
+
+<pre>
+	tableconstructor ::= &lsquo;<b>{</b>&rsquo; [fieldlist] &lsquo;<b>}</b>&rsquo;
+	fieldlist ::= field {fieldsep field} [fieldsep]
+	field ::= &lsquo;<b>[</b>&rsquo; exp &lsquo;<b>]</b>&rsquo; &lsquo;<b>=</b>&rsquo; exp | Name &lsquo;<b>=</b>&rsquo; exp | exp
+	fieldsep ::= &lsquo;<b>,</b>&rsquo; | &lsquo;<b>;</b>&rsquo;
+</pre>
+
+<p>
+Each field of the form <code>[exp1] = exp2</code> adds to the new table an entry
+with key <code>exp1</code> and value <code>exp2</code>.
+A field of the form <code>name = exp</code> is equivalent to
+<code>["name"] = exp</code>.
+Fields of the form <code>exp</code> are equivalent to
+<code>[i] = exp</code>, where <code>i</code> are consecutive integers
+starting with 1;
+fields in the other formats do not affect this counting.
+For example,
+
+<pre>
+     a = { [f(1)] = g; "x", "y"; x = 1, f(x), [30] = 23; 45 }
+</pre><p>
+is equivalent to
+
+<pre>
+     do
+       local t = {}
+       t[f(1)] = g
+       t[1] = "x"         -- 1st exp
+       t[2] = "y"         -- 2nd exp
+       t.x = 1            -- t["x"] = 1
+       t[3] = f(x)        -- 3rd exp
+       t[30] = 23
+       t[4] = 45          -- 4th exp
+       a = t
+     end
+</pre>
+
+<p>
+The order of the assignments in a constructor is undefined.
+(This order would be relevant only when there are repeated keys.)
+
+
+<p>
+If the last field in the list has the form <code>exp</code>
+and the expression is a multires expression,
+then all values returned by this expression enter the list consecutively
+(see <a href="#3.4.12">&sect;3.4.12</a>).
+
+
+<p>
+The field list can have an optional trailing separator,
+as a convenience for machine-generated code.
+
+
+
+
+
+<h3>3.4.10 &ndash; <a name="3.4.10">Function Calls</a></h3><p>
+A function call in Lua has the following syntax:
+
+<pre>
+	functioncall ::= prefixexp args
+</pre><p>
+In a function call,
+first prefixexp and args are evaluated.
+If the value of prefixexp has type <em>function</em>,
+then this function is called
+with the given arguments.
+Otherwise, if present,
+the prefixexp <code>__call</code> metamethod is called:
+its first argument is the value of prefixexp,
+followed by the original call arguments
+(see <a href="#2.4">&sect;2.4</a>).
+
+
+<p>
+The form
+
+<pre>
+	functioncall ::= prefixexp &lsquo;<b>:</b>&rsquo; Name args
+</pre><p>
+can be used to emulate methods.
+A call <code>v:name(<em>args</em>)</code>
+is syntactic sugar for <code>v.name(v,<em>args</em>)</code>,
+except that <code>v</code> is evaluated only once.
+
+
+<p>
+Arguments have the following syntax:
+
+<pre>
+	args ::= &lsquo;<b>(</b>&rsquo; [explist] &lsquo;<b>)</b>&rsquo;
+	args ::= tableconstructor
+	args ::= LiteralString
+</pre><p>
+All argument expressions are evaluated before the call.
+A call of the form <code>f{<em>fields</em>}</code> is
+syntactic sugar for <code>f({<em>fields</em>})</code>;
+that is, the argument list is a single new table.
+A call of the form <code>f'<em>string</em>'</code>
+(or <code>f"<em>string</em>"</code> or <code>f[[<em>string</em>]]</code>)
+is syntactic sugar for <code>f('<em>string</em>')</code>;
+that is, the argument list is a single literal string.
+
+
+<p>
+A call of the form <code>return <em>functioncall</em></code> not in the
+scope of a to-be-closed variable is called a <em>tail call</em>.
+Lua implements <em>proper tail calls</em>
+(or <em>proper tail recursion</em>):
+In a tail call,
+the called function reuses the stack entry of the calling function.
+Therefore, there is no limit on the number of nested tail calls that
+a program can execute.
+However, a tail call erases any debug information about the
+calling function.
+Note that a tail call only happens with a particular syntax,
+where the <b>return</b> has one single function call as argument,
+and it is outside the scope of any to-be-closed variable.
+This syntax makes the calling function return exactly
+the returns of the called function,
+without any intervening action.
+So, none of the following examples are tail calls:
+
+<pre>
+     return (f(x))        -- results adjusted to 1
+     return 2 * f(x)      -- result multiplied by 2
+     return x, f(x)       -- additional results
+     f(x); return         -- results discarded
+     return x or f(x)     -- results adjusted to 1
+</pre>
+
+
+
+
+<h3>3.4.11 &ndash; <a name="3.4.11">Function Definitions</a></h3>
+
+<p>
+The syntax for function definition is
+
+<pre>
+	functiondef ::= <b>function</b> funcbody
+	funcbody ::= &lsquo;<b>(</b>&rsquo; [parlist] &lsquo;<b>)</b>&rsquo; block <b>end</b>
+</pre>
+
+<p>
+The following syntactic sugar simplifies function definitions:
+
+<pre>
+	stat ::= <b>function</b> funcname funcbody
+	stat ::= <b>local</b> <b>function</b> Name funcbody
+	funcname ::= Name {&lsquo;<b>.</b>&rsquo; Name} [&lsquo;<b>:</b>&rsquo; Name]
+</pre><p>
+The statement
+
+<pre>
+     function f () <em>body</em> end
+</pre><p>
+translates to
+
+<pre>
+     f = function () <em>body</em> end
+</pre><p>
+The statement
+
+<pre>
+     function t.a.b.c.f () <em>body</em> end
+</pre><p>
+translates to
+
+<pre>
+     t.a.b.c.f = function () <em>body</em> end
+</pre><p>
+The statement
+
+<pre>
+     local function f () <em>body</em> end
+</pre><p>
+translates to
+
+<pre>
+     local f; f = function () <em>body</em> end
+</pre><p>
+not to
+
+<pre>
+     local f = function () <em>body</em> end
+</pre><p>
+(This only makes a difference when the body of the function
+contains references to <code>f</code>.)
+
+
+<p>
+A function definition is an executable expression,
+whose value has type <em>function</em>.
+When Lua precompiles a chunk,
+all its function bodies are precompiled too,
+but they are not created yet.
+Then, whenever Lua executes the function definition,
+the function is <em>instantiated</em> (or <em>closed</em>).
+This function instance, or <em>closure</em>,
+is the final value of the expression.
+
+
+<p>
+Parameters act as local variables that are
+initialized with the argument values:
+
+<pre>
+	parlist ::= namelist [&lsquo;<b>,</b>&rsquo; &lsquo;<b>...</b>&rsquo;] | &lsquo;<b>...</b>&rsquo;
+</pre><p>
+When a Lua function is called,
+it adjusts its list of arguments to
+the length of its list of parameters (see <a href="#3.4.12">&sect;3.4.12</a>),
+unless the function is a <em>variadic function</em>,
+which is indicated by three dots ('<code>...</code>')
+at the end of its parameter list.
+A variadic function does not adjust its argument list;
+instead, it collects all extra arguments and supplies them
+to the function through a <em>vararg expression</em>,
+which is also written as three dots.
+The value of this expression is a list of all actual extra arguments,
+similar to a function with multiple results (see <a href="#3.4.12">&sect;3.4.12</a>).
+
+
+<p>
+As an example, consider the following definitions:
+
+<pre>
+     function f(a, b) end
+     function g(a, b, ...) end
+     function r() return 1,2,3 end
+</pre><p>
+Then, we have the following mapping from arguments to parameters and
+to the vararg expression:
+
+<pre>
+     CALL             PARAMETERS
+     
+     f(3)             a=3, b=nil
+     f(3, 4)          a=3, b=4
+     f(3, 4, 5)       a=3, b=4
+     f(r(), 10)       a=1, b=10
+     f(r())           a=1, b=2
+     
+     g(3)             a=3, b=nil, ... --&gt;  (nothing)
+     g(3, 4)          a=3, b=4,   ... --&gt;  (nothing)
+     g(3, 4, 5, 8)    a=3, b=4,   ... --&gt;  5  8
+     g(5, r())        a=5, b=1,   ... --&gt;  2  3
+</pre>
+
+<p>
+Results are returned using the <b>return</b> statement (see <a href="#3.3.4">&sect;3.3.4</a>).
+If control reaches the end of a function
+without encountering a <b>return</b> statement,
+then the function returns with no results.
+
+
+<p>
+
+There is a system-dependent limit on the number of values
+that a function may return.
+This limit is guaranteed to be greater than 1000.
+
+
+<p>
+The <em>colon</em> syntax
+is used to emulate <em>methods</em>,
+adding an implicit extra parameter <code>self</code> to the function.
+Thus, the statement
+
+<pre>
+     function t.a.b.c:f (<em>params</em>) <em>body</em> end
+</pre><p>
+is syntactic sugar for
+
+<pre>
+     t.a.b.c.f = function (self, <em>params</em>) <em>body</em> end
+</pre>
+
+
+
+
+<h3>3.4.12 &ndash; <a name="3.4.12">Lists of expressions, multiple results,
+and adjustment</a></h3>
+
+<p>
+Both function calls and vararg expressions can result in multiple values.
+These expressions are called <em>multires expressions</em>.
+
+
+<p>
+When a multires expression is used as the last element
+of a list of expressions,
+all results from the expression are added to the
+list of values produced by the list of expressions.
+Note that a single expression
+in a place that expects a list of expressions
+is the last expression in that (singleton) list.
+
+
+<p>
+These are the places where Lua expects a list of expressions:
+
+<ul>
+
+<li>A <b>return</b> statement,
+for instance <code>return e1, e2, e3</code> (see <a href="#3.3.4">&sect;3.3.4</a>).</li>
+
+<li>A table constructor,
+for instance <code>{e1, e2, e3}</code> (see <a href="#3.4.9">&sect;3.4.9</a>).</li>
+
+<li>The arguments of a function call,
+for instance <code>foo(e1, e2, e3)</code> (see <a href="#3.4.10">&sect;3.4.10</a>).</li>
+
+<li>A multiple assignment,
+for instance <code>a , b, c = e1, e2, e3</code> (see <a href="#3.3.3">&sect;3.3.3</a>).</li>
+
+<li>A local declaration,
+for instance <code>local a , b, c = e1, e2, e3</code> (see <a href="#3.3.7">&sect;3.3.7</a>).</li>
+
+<li>The initial values in a generic <b>for</b> loop,
+for instance <code>for k in e1, e2, e3 do ... end</code> (see <a href="#3.3.5">&sect;3.3.5</a>).</li>
+
+</ul><p>
+In the last four cases,
+the list of values from the list of expressions
+must be <em>adjusted</em> to a specific length:
+the number of parameters in a call to a non-variadic function
+(see <a href="#3.4.11">&sect;3.4.11</a>),
+the number of variables in a multiple assignment or
+a local declaration,
+and exactly four values for a generic <b>for</b> loop.
+The <em>adjustment</em> follows these rules:
+If there are more values than needed,
+the extra values are thrown away;
+if there are fewer values than needed,
+the list is extended with <b>nil</b>'s.
+When the list of expressions ends with a multires expression,
+all results from that expression enter the list of values
+before the adjustment.
+
+
+<p>
+When a multires expression is used
+in a list of expressions without being the last element,
+or in a place where the syntax expects a single expression,
+Lua adjusts the result list of that expression to one element.
+As a particular case,
+the syntax expects a single expression inside a parenthesized expression;
+therefore, adding parentheses around a multires expression
+forces it to produce exactly one result.
+
+
+<p>
+We seldom need to use a vararg expression in a place
+where the syntax expects a single expression.
+(Usually it is simpler to add a regular parameter before
+the variadic part and use that parameter.)
+When there is such a need,
+we recommend assigning the vararg expression
+to a single variable and using that variable
+in its place.
+
+
+<p>
+Here are some examples of uses of mutlres expressions.
+In all cases, when the construction needs
+"the n-th result" and there is no such result,
+it uses a <b>nil</b>.
+
+<pre>
+     print(x, f())      -- prints x and all results from f().
+     print(x, (f()))    -- prints x and the first result from f().
+     print(f(), x)      -- prints the first result from f() and x.
+     print(1 + f())     -- prints 1 added to the first result from f().
+     local x = ...      -- x gets the first vararg argument.
+     x,y = ...          -- x gets the first vararg argument,
+                        -- y gets the second vararg argument.
+     x,y,z = w, f()     -- x gets w, y gets the first result from f(),
+                        -- z gets the second result from f().
+     x,y,z = f()        -- x gets the first result from f(),
+                        -- y gets the second result from f(),
+                        -- z gets the third result from f().
+     x,y,z = f(), g()   -- x gets the first result from f(),
+                        -- y gets the first result from g(),
+                        -- z gets the second result from g().
+     x,y,z = (f())      -- x gets the first result from f(), y and z get nil.
+     return f()         -- returns all results from f().
+     return x, ...      -- returns x and all received vararg arguments.
+     return x,y,f()     -- returns x, y, and all results from f().
+     {f()}              -- creates a list with all results from f().
+     {...}              -- creates a list with all vararg arguments.
+     {f(), 5}           -- creates a list with the first result from f() and 5.
+</pre>

+
+
+
+
+
+<h2>3.5 &ndash; <a name="3.5">Visibility Rules</a></h2>
+
+<p>
+
+Lua is a lexically scoped language.
+The scope of a local variable begins at the first statement after
+its declaration and lasts until the last non-void statement
+of the innermost block that includes the declaration.
+(<em>Void statements</em> are labels and empty statements.)
+Consider the following example:
+
+<pre>
+     x = 10                -- global variable
+     do                    -- new block
+       local x = x         -- new 'x', with value 10
+       print(x)            --&gt; 10
+       x = x+1
+       do                  -- another block
+         local x = x+1     -- another 'x'
+         print(x)          --&gt; 12
+       end
+       print(x)            --&gt; 11
+     end
+     print(x)              --&gt; 10  (the global one)
+</pre>
+
+<p>
+Notice that, in a declaration like <code>local x = x</code>,
+the new <code>x</code> being declared is not in scope yet,
+and so the second <code>x</code> refers to the outside variable.
+
+
+<p>
+Because of the lexical scoping rules,
+local variables can be freely accessed by functions
+defined inside their scope.
+A local variable used by an inner function is called an <em>upvalue</em>
+(or <em>external local variable</em>, or simply <em>external variable</em>)
+inside the inner function.
+
+
+<p>
+Notice that each execution of a <b>local</b> statement
+defines new local variables.
+Consider the following example:
+
+<pre>
+     a = {}
+     local x = 20
+     for i = 1, 10 do
+       local y = 0
+       a[i] = function () y = y + 1; return x + y end
+     end
+</pre><p>
+The loop creates ten closures
+(that is, ten instances of the anonymous function).
+Each of these closures uses a different <code>y</code> variable,
+while all of them share the same <code>x</code>.
+
+
+
+
+
+<h1>4 &ndash; <a name="4">The Application Program Interface</a></h1>
+
+
+
+<p>
+
+This section describes the C&nbsp;API for Lua, that is,
+the set of C&nbsp;functions available to the host program to communicate
+with Lua.
+All API functions and related types and constants
+are declared in the header file <a name="pdf-lua.h"><code>lua.h</code></a>.
+
+
+<p>
+Even when we use the term "function",
+any facility in the API may be provided as a macro instead.
+Except where stated otherwise,
+all such macros use each of their arguments exactly once
+(except for the first argument, which is always a Lua state),
+and so do not generate any hidden side-effects.
+
+
+<p>
+As in most C&nbsp;libraries,
+the Lua API functions do not check their arguments
+for validity or consistency.
+However, you can change this behavior by compiling Lua
+with the macro <a name="pdf-LUA_USE_APICHECK"><code>LUA_USE_APICHECK</code></a> defined.
+
+
+<p>
+The Lua library is fully reentrant:
+it has no global variables.
+It keeps all information it needs in a dynamic structure,
+called the <em>Lua state</em>.
+
+
+<p>
+Each Lua state has one or more threads,
+which correspond to independent, cooperative lines of execution.
+The type <a href="#lua_State"><code>lua_State</code></a> (despite its name) refers to a thread.
+(Indirectly, through the thread, it also refers to the
+Lua state associated to the thread.)
+
+
+<p>
+A pointer to a thread must be passed as the first argument to
+every function in the library, except to <a href="#lua_newstate"><code>lua_newstate</code></a>,
+which creates a Lua state from scratch and returns a pointer
+to the <em>main thread</em> in the new state.
+
+
+
+
+
+<h2>4.1 &ndash; <a name="4.1">The Stack</a></h2>
+
+
+
+<p>
+Lua uses a <em>virtual stack</em> to pass values to and from C.
+Each element in this stack represents a Lua value
+(<b>nil</b>, number, string, etc.).
+Functions in the API can access this stack through the
+Lua state parameter that they receive.
+
+
+<p>
+Whenever Lua calls C, the called function gets a new stack,
+which is independent of previous stacks and of stacks of
+C&nbsp;functions that are still active.
+This stack initially contains any arguments to the C&nbsp;function
+and it is where the C&nbsp;function can store temporary
+Lua values and must push its results
+to be returned to the caller (see <a href="#lua_CFunction"><code>lua_CFunction</code></a>).
+
+
+<p>
+For convenience,
+most query operations in the API do not follow a strict stack discipline.
+Instead, they can refer to any element in the stack
+by using an <em>index</em>:
+A positive index represents an absolute stack position,
+starting at&nbsp;1 as the bottom of the stack;
+a negative index represents an offset relative to the top of the stack.
+More specifically, if the stack has <em>n</em> elements,
+then index&nbsp;1 represents the first element
+(that is, the element that was pushed onto the stack first)
+and
+index&nbsp;<em>n</em> represents the last element;
+index&nbsp;-1 also represents the last element
+(that is, the element at the&nbsp;top)
+and index <em>-n</em> represents the first element.
+
+
+
+
+
+<h3>4.1.1 &ndash; <a name="4.1.1">Stack Size</a></h3>
+
+<p>
+When you interact with the Lua API,
+you are responsible for ensuring consistency.
+In particular,
+<em>you are responsible for controlling stack overflow</em>.
+When you call any API function,
+you must ensure the stack has enough room to accommodate the results.
+
+
+<p>
+There is one exception to the above rule:
+When you call a Lua function
+without a fixed number of results (see <a href="#lua_call"><code>lua_call</code></a>),
+Lua ensures that the stack has enough space for all results.
+However, it does not ensure any extra space.
+So, before pushing anything on the stack after such a call
+you should use <a href="#lua_checkstack"><code>lua_checkstack</code></a>.
+
+
+<p>
+Whenever Lua calls C,
+it ensures that the stack has space for
+at least <a name="pdf-LUA_MINSTACK"><code>LUA_MINSTACK</code></a> extra elements;
+that is, you can safely push up to <code>LUA_MINSTACK</code> values into it.
+<code>LUA_MINSTACK</code> is defined as 20,
+so that usually you do not have to worry about stack space
+unless your code has loops pushing elements onto the stack.
+Whenever necessary,
+you can use the function <a href="#lua_checkstack"><code>lua_checkstack</code></a>
+to ensure that the stack has enough space for pushing new elements.
+
+
+
+
+
+<h3>4.1.2 &ndash; <a name="4.1.2">Valid and Acceptable Indices</a></h3>
+
+<p>
+Any function in the API that receives stack indices
+works only with <em>valid indices</em> or <em>acceptable indices</em>.
+
+
+<p>
+A <em>valid index</em> is an index that refers to a
+position that stores a modifiable Lua value.
+It comprises stack indices between&nbsp;1 and the stack top
+(<code>1 &le; abs(index) &le; top</code>)
+
+plus <em>pseudo-indices</em>,
+which represent some positions that are accessible to C&nbsp;code
+but that are not in the stack.
+Pseudo-indices are used to access the registry (see <a href="#4.3">&sect;4.3</a>)
+and the upvalues of a C&nbsp;function (see <a href="#4.2">&sect;4.2</a>).
+
+
+<p>
+Functions that do not need a specific mutable position,
+but only a value (e.g., query functions),
+can be called with acceptable indices.
+An <em>acceptable index</em> can be any valid index,
+but it also can be any positive index after the stack top
+within the space allocated for the stack,
+that is, indices up to the stack size.
+(Note that 0 is never an acceptable index.)
+Indices to upvalues (see <a href="#4.2">&sect;4.2</a>) greater than the real number
+of upvalues in the current C&nbsp;function are also acceptable (but invalid).
+Except when noted otherwise,
+functions in the API work with acceptable indices.
+
+
+<p>
+Acceptable indices serve to avoid extra tests
+against the stack top when querying the stack.
+For instance, a C&nbsp;function can query its third argument
+without the need to check whether there is a third argument,
+that is, without the need to check whether 3 is a valid index.
+
+
+<p>
+For functions that can be called with acceptable indices,
+any non-valid index is treated as if it
+contains a value of a virtual type <a name="pdf-LUA_TNONE"><code>LUA_TNONE</code></a>,
+which behaves like a nil value.
+
+
+
+
+
+<h3>4.1.3 &ndash; <a name="4.1.3">Pointers to strings</a></h3>
+
+<p>
+Several functions in the API return pointers (<code>const char*</code>)
+to Lua strings in the stack.
+(See <a href="#lua_pushfstring"><code>lua_pushfstring</code></a>, <a href="#lua_pushlstring"><code>lua_pushlstring</code></a>,
+<a href="#lua_pushstring"><code>lua_pushstring</code></a>, and <a href="#lua_tolstring"><code>lua_tolstring</code></a>.
+See also <a href="#luaL_checklstring"><code>luaL_checklstring</code></a>, <a href="#luaL_checkstring"><code>luaL_checkstring</code></a>,
+and <a href="#luaL_tolstring"><code>luaL_tolstring</code></a> in the auxiliary library.)
+
+
+<p>
+In general,
+Lua's garbage collection can free or move internal memory
+and then invalidate pointers to internal strings.
+To allow a safe use of these pointers,
+the API guarantees that any pointer to a string in a stack index
+is valid while the string value at that index is not removed from the stack.
+(It can be moved to another index, though.)
+When the index is a pseudo-index (referring to an upvalue),
+the pointer is valid while the corresponding call is active and
+the corresponding upvalue is not modified.
+
+
+<p>
+Some functions in the debug interface
+also return pointers to strings,
+namely <a href="#lua_getlocal"><code>lua_getlocal</code></a>, <a href="#lua_getupvalue"><code>lua_getupvalue</code></a>,
+<a href="#lua_setlocal"><code>lua_setlocal</code></a>, and <a href="#lua_setupvalue"><code>lua_setupvalue</code></a>.
+For these functions, the pointer is guaranteed to
+be valid while the caller function is active and
+the given closure (if one was given) is in the stack.
+
+
+<p>
+Except for these guarantees,
+the garbage collector is free to invalidate
+any pointer to internal strings.
+
+
+
+
+
+
+
+<h2>4.2 &ndash; <a name="4.2">C Closures</a></h2>
+
+<p>
+When a C&nbsp;function is created,
+it is possible to associate some values with it,
+thus creating a <em>C&nbsp;closure</em>
+(see <a href="#lua_pushcclosure"><code>lua_pushcclosure</code></a>);
+these values are called <em>upvalues</em> and are
+accessible to the function whenever it is called.
+
+
+<p>
+Whenever a C&nbsp;function is called,
+its upvalues are located at specific pseudo-indices.
+These pseudo-indices are produced by the macro
+<a href="#lua_upvalueindex"><code>lua_upvalueindex</code></a>.
+The first upvalue associated with a function is at index
+<code>lua_upvalueindex(1)</code>, and so on.
+Any access to <code>lua_upvalueindex(<em>n</em>)</code>,
+where <em>n</em> is greater than the number of upvalues of the
+current function
+(but not greater than 256,
+which is one plus the maximum number of upvalues in a closure),
+produces an acceptable but invalid index.
+
+
+<p>
+A C&nbsp;closure can also change the values
+of its corresponding upvalues.
+
+
+
+
+
+<h2>4.3 &ndash; <a name="4.3">Registry</a></h2>
+
+<p>
+Lua provides a <em>registry</em>,
+a predefined table that can be used by any C&nbsp;code to
+store whatever Lua values it needs to store.
+The registry table is always accessible at pseudo-index
+<a name="pdf-LUA_REGISTRYINDEX"><code>LUA_REGISTRYINDEX</code></a>.
+Any C&nbsp;library can store data into this table,
+but it must take care to choose keys
+that are different from those used
+by other libraries, to avoid collisions.
+Typically, you should use as key a string containing your library name,
+or a light userdata with the address of a C&nbsp;object in your code,
+or any Lua object created by your code.
+As with variable names,
+string keys starting with an underscore followed by
+uppercase letters are reserved for Lua.
+
+
+<p>
+The integer keys in the registry are used
+by the reference mechanism (see <a href="#luaL_ref"><code>luaL_ref</code></a>)
+and by some predefined values.
+Therefore, integer keys in the registry
+must not be used for other purposes.
+
+
+<p>
+When you create a new Lua state,
+its registry comes with some predefined values.
+These predefined values are indexed with integer keys
+defined as constants in <code>lua.h</code>.
+The following constants are defined:
+
+<ul>
+<li><b><a name="pdf-LUA_RIDX_MAINTHREAD"><code>LUA_RIDX_MAINTHREAD</code></a>: </b> At this index the registry has
+the main thread of the state.
+(The main thread is the one created together with the state.)
+</li>
+
+<li><b><a name="pdf-LUA_RIDX_GLOBALS"><code>LUA_RIDX_GLOBALS</code></a>: </b> At this index the registry has
+the global environment.
+</li>
+</ul>
+
+
+
+
+<h2>4.4 &ndash; <a name="4.4">Error Handling in C</a></h2>
+
+
+
+<p>
+Internally, Lua uses the C <code>longjmp</code> facility to handle errors.
+(Lua will use exceptions if you compile it as C++;
+search for <code>LUAI_THROW</code> in the source code for details.)
+When Lua faces any error,
+such as a memory allocation error or a type error,
+it <em>raises</em> an error;
+that is, it does a long jump.
+A <em>protected environment</em> uses <code>setjmp</code>
+to set a recovery point;
+any error jumps to the most recent active recovery point.
+
+
+<p>
+Inside a C&nbsp;function you can raise an error explicitly
+by calling <a href="#lua_error"><code>lua_error</code></a>.
+
+
+<p>
+Most functions in the API can raise an error,
+for instance due to a memory allocation error.
+The documentation for each function indicates whether
+it can raise errors.
+
+
+<p>
+If an error happens outside any protected environment,
+Lua calls a <em>panic function</em> (see <a href="#lua_atpanic"><code>lua_atpanic</code></a>)
+and then calls <code>abort</code>,
+thus exiting the host application.
+Your panic function can avoid this exit by
+never returning
+(e.g., doing a long jump to your own recovery point outside Lua).
+
+
+<p>
+The panic function,
+as its name implies,
+is a mechanism of last resort.
+Programs should avoid it.
+As a general rule,
+when a C&nbsp;function is called by Lua with a Lua state,
+it can do whatever it wants on that Lua state,
+as it should be already protected.
+However,
+when C code operates on other Lua states
+(e.g., a Lua-state argument to the function,
+a Lua state stored in the registry, or
+the result of <a href="#lua_newthread"><code>lua_newthread</code></a>),
+it should use them only in API calls that cannot raise errors.
+
+
+<p>
+The panic function runs as if it were a message handler (see <a href="#2.3">&sect;2.3</a>);
+in particular, the error object is on the top of the stack.
+However, there is no guarantee about stack space.
+To push anything on the stack,
+the panic function must first check the available space (see <a href="#4.1.1">&sect;4.1.1</a>).
+
+
+
+
+
+<h3>4.4.1 &ndash; <a name="4.4.1">Status Codes</a></h3>
+
+<p>
+Several functions that report errors in the API use the following
+status codes to indicate different kinds of errors or other conditions:
+
+<ul>
+
+<li><b><a name="pdf-LUA_OK"><code>LUA_OK</code></a> (0): </b> no errors.</li>
+
+<li><b><a name="pdf-LUA_ERRRUN"><code>LUA_ERRRUN</code></a>: </b> a runtime error.</li>
+
+<li><b><a name="pdf-LUA_ERRMEM"><code>LUA_ERRMEM</code></a>: </b>
+memory allocation error.
+For such errors, Lua does not call the message handler.
+</li>
+
+<li><b><a name="pdf-LUA_ERRERR"><code>LUA_ERRERR</code></a>: </b> error while running the message handler.</li>
+
+<li><b><a name="pdf-LUA_ERRSYNTAX"><code>LUA_ERRSYNTAX</code></a>: </b> syntax error during precompilation.</li>
+
+<li><b><a name="pdf-LUA_YIELD"><code>LUA_YIELD</code></a>: </b> the thread (coroutine) yields.</li>
+
+<li><b><a name="pdf-LUA_ERRFILE"><code>LUA_ERRFILE</code></a>: </b> a file-related error;
+e.g., it cannot open or read the file.</li>
+
+</ul><p>
+These constants are defined in the header file <code>lua.h</code>.
+
+
+
+
+
+
+
+<h2>4.5 &ndash; <a name="4.5">Handling Yields in C</a></h2>
+
+<p>
+Internally, Lua uses the C <code>longjmp</code> facility to yield a coroutine.
+Therefore, if a C&nbsp;function <code>foo</code> calls an API function
+and this API function yields
+(directly or indirectly by calling another function that yields),
+Lua cannot return to <code>foo</code> any more,
+because the <code>longjmp</code> removes its frame from the C&nbsp;stack.
+
+
+<p>
+To avoid this kind of problem,
+Lua raises an error whenever it tries to yield across an API call,
+except for three functions:
+<a href="#lua_yieldk"><code>lua_yieldk</code></a>, <a href="#lua_callk"><code>lua_callk</code></a>, and <a href="#lua_pcallk"><code>lua_pcallk</code></a>.
+All those functions receive a <em>continuation function</em>
+(as a parameter named <code>k</code>) to continue execution after a yield.
+
+
+<p>
+We need to set some terminology to explain continuations.
+We have a C&nbsp;function called from Lua which we will call
+the <em>original function</em>.
+This original function then calls one of those three functions in the C API,
+which we will call the <em>callee function</em>,
+that then yields the current thread.
+This can happen when the callee function is <a href="#lua_yieldk"><code>lua_yieldk</code></a>,
+or when the callee function is either <a href="#lua_callk"><code>lua_callk</code></a> or <a href="#lua_pcallk"><code>lua_pcallk</code></a>
+and the function called by them yields.
+
+
+<p>
+Suppose the running thread yields while executing the callee function.
+After the thread resumes,
+it eventually will finish running the callee function.
+However,
+the callee function cannot return to the original function,
+because its frame in the C&nbsp;stack was destroyed by the yield.
+Instead, Lua calls a <em>continuation function</em>,
+which was given as an argument to the callee function.
+As the name implies,
+the continuation function should continue the task
+of the original function.
+
+
+<p>
+As an illustration, consider the following function:
+
+<pre>
+     int original_function (lua_State *L) {
+       ...     /* code 1 */
+       status = lua_pcall(L, n, m, h);  /* calls Lua */
+       ...     /* code 2 */
+     }
+</pre><p>
+Now we want to allow
+the Lua code being run by <a href="#lua_pcall"><code>lua_pcall</code></a> to yield.
+First, we can rewrite our function like here:
+
+<pre>
+     int k (lua_State *L, int status, lua_KContext ctx) {
+       ...  /* code 2 */
+     }
+     
+     int original_function (lua_State *L) {
+       ...     /* code 1 */
+       return k(L, lua_pcall(L, n, m, h), ctx);
+     }
+</pre><p>
+In the above code,
+the new function <code>k</code> is a
+<em>continuation function</em> (with type <a href="#lua_KFunction"><code>lua_KFunction</code></a>),
+which should do all the work that the original function
+was doing after calling <a href="#lua_pcall"><code>lua_pcall</code></a>.
+Now, we must inform Lua that it must call <code>k</code> if the Lua code
+being executed by <a href="#lua_pcall"><code>lua_pcall</code></a> gets interrupted in some way
+(errors or yielding),
+so we rewrite the code as here,
+replacing <a href="#lua_pcall"><code>lua_pcall</code></a> by <a href="#lua_pcallk"><code>lua_pcallk</code></a>:
+
+<pre>
+     int original_function (lua_State *L) {
+       ...     /* code 1 */
+       return k(L, lua_pcallk(L, n, m, h, ctx2, k), ctx1);
+     }
+</pre><p>
+Note the external, explicit call to the continuation:
+Lua will call the continuation only if needed, that is,
+in case of errors or resuming after a yield.
+If the called function returns normally without ever yielding,
+<a href="#lua_pcallk"><code>lua_pcallk</code></a> (and <a href="#lua_callk"><code>lua_callk</code></a>) will also return normally.
+(Of course, instead of calling the continuation in that case,
+you can do the equivalent work directly inside the original function.)
+
+
+<p>
+Besides the Lua state,
+the continuation function has two other parameters:
+the final status of the call and the context value (<code>ctx</code>) that
+was passed originally to <a href="#lua_pcallk"><code>lua_pcallk</code></a>.
+Lua does not use this context value;
+it only passes this value from the original function to the
+continuation function.
+For <a href="#lua_pcallk"><code>lua_pcallk</code></a>,
+the status is the same value that would be returned by <a href="#lua_pcallk"><code>lua_pcallk</code></a>,
+except that it is <a href="#pdf-LUA_YIELD"><code>LUA_YIELD</code></a> when being executed after a yield
+(instead of <a href="#pdf-LUA_OK"><code>LUA_OK</code></a>).
+For <a href="#lua_yieldk"><code>lua_yieldk</code></a> and <a href="#lua_callk"><code>lua_callk</code></a>,
+the status is always <a href="#pdf-LUA_YIELD"><code>LUA_YIELD</code></a> when Lua calls the continuation.
+(For these two functions,
+Lua will not call the continuation in case of errors,
+because they do not handle errors.)
+Similarly, when using <a href="#lua_callk"><code>lua_callk</code></a>,
+you should call the continuation function
+with <a href="#pdf-LUA_OK"><code>LUA_OK</code></a> as the status.
+(For <a href="#lua_yieldk"><code>lua_yieldk</code></a>, there is not much point in calling
+directly the continuation function,
+because <a href="#lua_yieldk"><code>lua_yieldk</code></a> usually does not return.)
+
+
+<p>
+Lua treats the continuation function as if it were the original function.
+The continuation function receives the same Lua stack
+from the original function,
+in the same state it would be if the callee function had returned.
+(For instance,
+after a <a href="#lua_callk"><code>lua_callk</code></a> the function and its arguments are
+removed from the stack and replaced by the results from the call.)
+It also has the same upvalues.
+Whatever it returns is handled by Lua as if it were the return
+of the original function.
+
+
+
+
+
+<h2>4.6 &ndash; <a name="4.6">Functions and Types</a></h2>
+
+<p>
+Here we list all functions and types from the C&nbsp;API in
+alphabetical order.
+Each function has an indicator like this:
+<span class="apii">[-o, +p, <em>x</em>]</span>
+
+
+<p>
+The first field, <code>o</code>,
+is how many elements the function pops from the stack.
+The second field, <code>p</code>,
+is how many elements the function pushes onto the stack.
+(Any function always pushes its results after popping its arguments.)
+A field in the form <code>x|y</code> means the function can push (or pop)
+<code>x</code> or <code>y</code> elements,
+depending on the situation;
+an interrogation mark '<code>?</code>' means that
+we cannot know how many elements the function pops/pushes
+by looking only at its arguments.
+(For instance, they may depend on what is in the stack.)
+The third field, <code>x</code>,
+tells whether the function may raise errors:
+'<code>-</code>' means the function never raises any error;
+'<code>m</code>' means the function may raise only out-of-memory errors;
+'<code>v</code>' means the function may raise the errors explained in the text;
+'<code>e</code>' means the function can run arbitrary Lua code,
+either directly or through metamethods,
+and therefore may raise any errors.

+
+<p>
+The type of the memory-allocation function used by Lua states.
+The allocator function must provide a
+functionality similar to <code>realloc</code>,
+but not exactly the same.
+Its arguments are
+<code>ud</code>, an opaque pointer passed to <a href="#lua_newstate"><code>lua_newstate</code></a>;
+<code>ptr</code>, a pointer to the block being allocated/reallocated/freed;
+<code>osize</code>, the original size of the block or some code about what
+is being allocated;
+and <code>nsize</code>, the new size of the block.
+
+
+<p>
+When <code>ptr</code> is not <code>NULL</code>,
+<code>osize</code> is the size of the block pointed by <code>ptr</code>,
+that is, the size given when it was allocated or reallocated.
+
+
+<p>
+When <code>ptr</code> is <code>NULL</code>,
+<code>osize</code> encodes the kind of object that Lua is allocating.
+<code>osize</code> is any of
+<a href="#pdf-LUA_TSTRING"><code>LUA_TSTRING</code></a>, <a href="#pdf-LUA_TTABLE"><code>LUA_TTABLE</code></a>, <a href="#pdf-LUA_TFUNCTION"><code>LUA_TFUNCTION</code></a>,
+<a href="#pdf-LUA_TUSERDATA"><code>LUA_TUSERDATA</code></a>, or <a href="#pdf-LUA_TTHREAD"><code>LUA_TTHREAD</code></a> when (and only when)
+Lua is creating a new object of that type.
+When <code>osize</code> is some other value,
+Lua is allocating memory for something else.
+
+
+<p>
+Lua assumes the following behavior from the allocator function:
+
+
+<p>
+When <code>nsize</code> is zero,
+the allocator must behave like <code>free</code>
+and then return <code>NULL</code>.
+
+
+<p>
+When <code>nsize</code> is not zero,
+the allocator must behave like <code>realloc</code>.
+In particular, the allocator returns <code>NULL</code>
+if and only if it cannot fulfill the request.
+
+
+<p>
+Here is a simple implementation for the allocator function.
+It is used in the auxiliary library by <a href="#luaL_newstate"><code>luaL_newstate</code></a>.
+
+<pre>
+     static void *l_alloc (void *ud, void *ptr, size_t osize,

+         return NULL;
+       }
+       else
+         return realloc(ptr, nsize);
+     }
+</pre><p>
+Note that ISO&nbsp;C ensures
+that <code>free(NULL)</code> has no effect and that
+<code>realloc(NULL,size)</code> is equivalent to <code>malloc(size)</code>.

+
+<p>
+Calls a function.
+Like regular Lua calls,
+<code>lua_call</code> respects the <code>__call</code> metamethod.
+So, here the word "function"
+means any callable value.
+
+
+<p>
+To do a call you must use the following protocol:
+first, the function to be called is pushed onto the stack;
+then, the arguments to the call are pushed
+in direct order;
+that is, the first argument is pushed first.
+Finally you call <a href="#lua_call"><code>lua_call</code></a>;
+<code>nargs</code> is the number of arguments that you pushed onto the stack.
+When the function returns,
+all arguments and the function value are popped
+and the call results are pushed onto the stack.
+The number of results is adjusted to <code>nresults</code>,
+unless <code>nresults</code> is <a name="pdf-LUA_MULTRET"><code>LUA_MULTRET</code></a>.
+In this case, all results from the function are pushed;
+Lua takes care that the returned values fit into the stack space,
+but it does not ensure any extra space in the stack.
+The function results are pushed onto the stack in direct order
+(the first result is pushed first),
+so that after the call the last result is on the top of the stack.
+
+
+<p>
+Any error while calling and running the function is propagated upwards
+(with a <code>longjmp</code>).
+
+
+<p>
+The following example shows how the host program can do the
+equivalent to this Lua code:
+
+<pre>
+     a = f("how", t.x, 14)
+</pre><p>
+Here it is in&nbsp;C:
+
+<pre>
+     lua_getglobal(L, "f");                  /* function to be called */
+     lua_pushliteral(L, "how");                       /* 1st argument */

+     lua_getfield(L, -1, "x");        /* push result of t.x (2nd arg) */
+     lua_remove(L, -2);                  /* remove 't' from the stack */
+     lua_pushinteger(L, 14);                          /* 3rd argument */

+     lua_setglobal(L, "a");                         /* set global 'a' */
+</pre><p>
+Note that the code above is <em>balanced</em>:
+at its end, the stack is back to its original configuration.
+This is considered good programming practice.

+
+
+<p>
+In order to communicate properly with Lua,
+a C&nbsp;function must use the following protocol,
+which defines the way parameters and results are passed:
+a C&nbsp;function receives its arguments from Lua in its stack
+in direct order (the first argument is pushed first).
+So, when the function starts,
+<code>lua_gettop(L)</code> returns the number of arguments received by the function.
+The first argument (if any) is at index 1
+and its last argument is at index <code>lua_gettop(L)</code>.
+To return values to Lua, a C&nbsp;function just pushes them onto the stack,
+in direct order (the first result is pushed first),
+and returns in C the number of results.
+Any other value in the stack below the results will be properly
+discarded by Lua.
+Like a Lua function, a C&nbsp;function called by Lua can also return
+many results.
+
+
+<p>
+As an example, the following function receives a variable number
+of numeric arguments and returns their average and their sum:

+Pushes a new C&nbsp;closure onto the stack.
+This function receives a pointer to a C&nbsp;function
+and pushes onto the stack a Lua value of type <code>function</code> that,
+when called, invokes the corresponding C&nbsp;function.
+The parameter <code>n</code> tells how many upvalues this function will have
+(see <a href="#4.2">&sect;4.2</a>).
+
+

+Any function to be callable by Lua must
+follow the correct protocol to receive its parameters
+and return its results (see <a href="#lua_CFunction"><code>lua_CFunction</code></a>).
+
+
+<p>
+When a C&nbsp;function is created,
+it is possible to associate some values with it,
+the so called upvalues;
+these upvalues are then accessible to the function whenever it is called.
+This association is called a C&nbsp;closure (see <a href="#4.2">&sect;4.2</a>).
+To create a C&nbsp;closure,
+first the initial values for its upvalues must be pushed onto the stack.
+(When there are multiple upvalues, the first value is pushed first.)
+Then <a href="#lua_pushcclosure"><code>lua_pushcclosure</code></a>

+
+
+<p>
+The maximum value for <code>n</code> is 255.

+It is similar to the ISO&nbsp;C function <code>sprintf</code>,
+but has two important differences.
+First,
+you do not have to allocate space for the result;
+the result is a Lua string and Lua takes care of memory allocation
+(and deallocation, through garbage collection).
+Second,
+the conversion specifiers are quite restricted.
+There are no flags, widths, or precisions.
+The conversion specifiers can only be
+'<code>%%</code>' (inserts the character '<code>%</code>'),
+'<code>%s</code>' (inserts a zero-terminated string, with no size restrictions),
+'<code>%f</code>' (inserts a <a href="#lua_Number"><code>lua_Number</code></a>),

+and the call to <a href="#lua_resume"><code>lua_resume</code></a> that started this coroutine returns.
+The parameter <code>nresults</code> is the number of values from the stack
+that will be passed as results to <a href="#lua_resume"><code>lua_resume</code></a>.
+
+

+When the coroutine is resumed again,
+Lua calls the given continuation function <code>k</code> to continue

+However, there is one special case,
+which is when this function is called

+In that case, <code>lua_yieldk</code> should be called with no continuation
+(probably in the form of <a href="#lua_yield"><code>lua_yield</code></a>) and no results,

+Lua will yield and,
+when the coroutine resumes again,
+it will continue the normal execution
+of the (Lua) function that triggered the hook.

+
+<p>
+This function can raise an error if it is called from a thread

+
+<p>
+A structure used to carry different pieces of
+information about a function or an activation record.
+<a href="#lua_getstack"><code>lua_getstack</code></a> fills only the private part
+of this structure, for later use.
+To fill the other fields of <a href="#lua_Debug"><code>lua_Debug</code></a> with useful information,
+you must call <a href="#lua_getinfo"><code>lua_getinfo</code></a> with an appropriate parameter.
+(Specifically, to get a field,
+you must add the letter between parentheses in the field's comment
+to the parameter <code>what</code> of <a href="#lua_getinfo"><code>lua_getinfo</code></a>.)
+
+
+<p>
+The fields of <a href="#lua_Debug"><code>lua_Debug</code></a> have the following meaning:
+
+<ul>
+
+<li><b><code>source</code>: </b>
+the source of the chunk that created the function.
+If <code>source</code> starts with a '<code>@</code>',
+it means that the function was defined in a file where
+the file name follows the '<code>@</code>'.
+If <code>source</code> starts with a '<code>=</code>',
+the remainder of its contents describes the source in a user-dependent manner.
+Otherwise,
+the function was defined in a string where
+<code>source</code> is that string.
+</li>
+
+<li><b><code>srclen</code>: </b>
+The length of the string <code>source</code>.
+</li>
+
+<li><b><code>short_src</code>: </b>
+a "printable" version of <code>source</code>, to be used in error messages.
+</li>
+
+<li><b><code>linedefined</code>: </b>
+the line number where the definition of the function starts.
+</li>
+
+<li><b><code>lastlinedefined</code>: </b>
+the line number where the definition of the function ends.
+</li>
+
+<li><b><code>what</code>: </b>
+the string <code>"Lua"</code> if the function is a Lua function,
+<code>"C"</code> if it is a C&nbsp;function,
+<code>"main"</code> if it is the main part of a chunk.
+</li>
+
+<li><b><code>currentline</code>: </b>
+the current line where the given function is executing.
+When no line information is available,
+<code>currentline</code> is set to -1.
+</li>
+
+<li><b><code>name</code>: </b>
+a reasonable name for the given function.
+Because functions in Lua are first-class values,
+they do not have a fixed name:
+some functions can be the value of multiple global variables,
+while others can be stored only in a table field.
+The <code>lua_getinfo</code> function checks how the function was
+called to find a suitable name.
+If it cannot find a name,
+then <code>name</code> is set to <code>NULL</code>.
+</li>
+
+<li><b><code>namewhat</code>: </b>
+explains the <code>name</code> field.
+The value of <code>namewhat</code> can be
+<code>"global"</code>, <code>"local"</code>, <code>"method"</code>,
+<code>"field"</code>, <code>"upvalue"</code>, or <code>""</code> (the empty string),
+according to how the function was called.
+(Lua uses the empty string when no other option seems to apply.)
+</li>
+
+<li><b><code>istailcall</code>: </b>
+true if this function invocation was called by a tail call.
+In this case, the caller of this level is not in the stack.
+</li>
+
+<li><b><code>nups</code>: </b>
+the number of upvalues of the function.
+</li>
+
+<li><b><code>nparams</code>: </b>
+the number of parameters of the function
+(always 0&nbsp;for C&nbsp;functions).
+</li>
+
+<li><b><code>isvararg</code>: </b>
+true if the function is a variadic function
+(always true for C&nbsp;functions).
+</li>
+
+<li><b><code>ftransfer</code>: </b>
+the index in the stack of the first value being "transferred",
+that is, parameters in a call or return values in a return.
+(The other values are in consecutive indices.)
+Using this index, you can access and modify these values
+through <a href="#lua_getlocal"><code>lua_getlocal</code></a> and <a href="#lua_setlocal"><code>lua_setlocal</code></a>.
+This field is only meaningful during a
+call hook, denoting the first parameter,
+or a return hook, denoting the first value being returned.
+(For call hooks, this value is always 1.)
+</li>
+
+<li><b><code>ntransfer</code>: </b>
+The number of values being transferred (see previous item).
+(For calls of Lua functions,
+this value is always equal to <code>nparams</code>.)

+Whenever a hook is called, its <code>ar</code> argument has its field

+Moreover, for line events, the field <code>currentline</code> is also set.
+To get the value of any other field in <code>ar</code>,
+the hook must call <a href="#lua_getinfo"><code>lua_getinfo</code></a>.
+
+
+<p>
+For call events, <code>event</code> can be <code>LUA_HOOKCALL</code>,

+<h1>5 &ndash; <a name="5">The Auxiliary Library</a></h1>
+
+
+
+<p>
+
+The <em>auxiliary library</em> provides several convenient functions
+to interface C with Lua.
+While the basic API provides the primitive functions for all
+interactions between C and Lua,
+the auxiliary library provides higher-level functions for some
+common tasks.
+
+
+<p>
+All functions and types from the auxiliary library
+are defined in header file <code>lauxlib.h</code> and
+have a prefix <code>luaL_</code>.
+
+
+<p>
+All functions in the auxiliary library are built on
+top of the basic API,
+and so they provide nothing that cannot be done with that API.
+Nevertheless, the use of the auxiliary library ensures
+more consistency to your code.
+
+
+<p>
+Several functions in the auxiliary library use internally some
+extra stack slots.
+When a function in the auxiliary library uses less than five slots,
+it does not check the stack size;
+it simply assumes that there are enough slots.
+
+
+<p>
+Several functions in the auxiliary library are used to
+check C&nbsp;function arguments.
+Because the error message is formatted for arguments
+(e.g., "<code>bad argument #1</code>"),
+you should not use these functions for other stack values.
+
+
+<p>
+Functions called <code>luaL_check*</code>
+always raise an error if the check is not satisfied.

+<hr><h3><a name="luaL_Buffer"><code>luaL_Buffer</code></a></h3>
+<pre>typedef struct luaL_Buffer luaL_Buffer;</pre>
+
+<p>
+Type for a <em>string buffer</em>.
+
+
+<p>
+A string buffer allows C&nbsp;code to build Lua strings piecemeal.
+Its pattern of use is as follows:
+
+<ul>
+
+<li>First declare a variable <code>b</code> of type <a href="#luaL_Buffer"><code>luaL_Buffer</code></a>.</li>
+
+<li>Then initialize it with a call <code>luaL_buffinit(L, &amp;b)</code>.</li>
+
+<li>
+Then add string pieces to the buffer calling any of
+the <code>luaL_add*</code> functions.
+</li>
+
+<li>
+Finish by calling <code>luaL_pushresult(&amp;b)</code>.
+This call leaves the final string on the top of the stack.
+</li>
+
+</ul>
+
+<p>
+If you know beforehand the maximum size of the resulting string,
+you can use the buffer like this:
+
+<ul>
+
+<li>First declare a variable <code>b</code> of type <a href="#luaL_Buffer"><code>luaL_Buffer</code></a>.</li>
+
+<li>Then initialize it and preallocate a space of
+size <code>sz</code> with a call <code>luaL_buffinitsize(L, &amp;b, sz)</code>.</li>
+
+<li>Then produce the string into that space.</li>
+
+<li>
+Finish by calling <code>luaL_pushresultsize(&amp;b, sz)</code>,
+where <code>sz</code> is the total size of the resulting string
+copied into that space (which may be less than or
+equal to the preallocated size).
+</li>
+
+</ul>
+
+<p>
+During its normal operation,
+a string buffer uses a variable number of stack slots.
+So, while using a buffer, you cannot assume that you know where
+the top of the stack is.
+You can use the stack between successive calls to buffer operations
+as long as that use is balanced;
+that is,
+when you call a buffer operation,
+the stack is at the same level
+it was immediately after the previous buffer operation.
+(The only exception to this rule is <a href="#luaL_addvalue"><code>luaL_addvalue</code></a>.)
+After calling <a href="#luaL_pushresult"><code>luaL_pushresult</code></a>,
+the stack is back to its level when the buffer was initialized,
+plus the final string on its top.

+<h1>6 &ndash; <a name="6">The Standard Libraries</a></h1>
+
+
+
+<p>
+The standard Lua libraries provide useful functions
+that are implemented in&nbsp;C through the C&nbsp;API.
+Some of these functions provide essential services to the language
+(e.g., <a href="#pdf-type"><code>type</code></a> and <a href="#pdf-getmetatable"><code>getmetatable</code></a>);
+others provide access to outside services (e.g., I/O);
+and others could be implemented in Lua itself,
+but that for different reasons
+deserve an implementation in C (e.g., <a href="#pdf-table.sort"><code>table.sort</code></a>).
+
+
+<p>
+All libraries are implemented through the official C&nbsp;API
+and are provided as separate C&nbsp;modules.
+Unless otherwise noted,
+these library functions do not adjust its number of arguments
+to its expected parameters.
+For instance, a function documented as <code>foo(arg)</code>
+should not be called without an argument.
+
+
+<p>
+The notation <b>fail</b> means a false value representing
+some kind of failure.
+(Currently, <b>fail</b> is equal to <b>nil</b>,
+but that may change in future versions.
+The recommendation is to always test the success of these functions
+with <code>(not status)</code>, instead of <code>(status == nil)</code>.)
+
+
+<p>
+Currently, Lua has the following standard libraries:
+
+<ul>
+
+<li>basic library (<a href="#6.1">&sect;6.1</a>);</li>
+
+<li>coroutine library (<a href="#6.2">&sect;6.2</a>);</li>
+
+<li>package library (<a href="#6.3">&sect;6.3</a>);</li>
+
+<li>string manipulation (<a href="#6.4">&sect;6.4</a>);</li>
+
+<li>basic UTF-8 support (<a href="#6.5">&sect;6.5</a>);</li>
+
+<li>table manipulation (<a href="#6.6">&sect;6.6</a>);</li>
+
+<li>mathematical functions (<a href="#6.7">&sect;6.7</a>) (sin, log, etc.);</li>
+
+<li>input and output (<a href="#6.8">&sect;6.8</a>);</li>
+
+<li>operating system facilities (<a href="#6.9">&sect;6.9</a>);</li>
+
+<li>debug facilities (<a href="#6.10">&sect;6.10</a>).</li>
+
+</ul><p>
+Except for the basic and the package libraries,
+each library provides all its functions as fields of a global table
+or as methods of its objects.
+
+
+<p>
+To have access to these libraries,
+the C&nbsp;host program should call the <a href="#luaL_openlibs"><code>luaL_openlibs</code></a> function,
+which opens all standard libraries.
+Alternatively,

+<h2>6.1 &ndash; <a name="6.1">Basic Functions</a></h2>
+
+<p>
+The basic library provides core functions to Lua.
+If you do not include this library in your application,
+you should check carefully whether you need to provide
+implementations for some of its facilities.
+
+
+<p>
+<hr><h3><a name="pdf-assert"><code>assert (v [, message])</code></a></h3>
+
+
+<p>
+Raises an error if
+the value of its argument <code>v</code> is false (i.e., <b>nil</b> or <b>false</b>);
+otherwise, returns all its arguments.
+In case of error,
+<code>message</code> is the error object;
+when absent, it defaults to "<code>assertion failed!</code>"
+
+
+
+
+<p>
+<hr><h3><a name="pdf-collectgarbage"><code>collectgarbage ([opt [, arg]])</code></a></h3>
+
+
+<p>
+This function is a generic interface to the garbage collector.
+It performs different functions according to its first argument, <code>opt</code>:
+
+<ul>
+
+<li><b>"<code>collect</code>": </b>
+Performs a full garbage-collection cycle.
+This is the default option.
+</li>
+
+<li><b>"<code>stop</code>": </b>
+Stops automatic execution of the garbage collector.
+The collector will run only when explicitly invoked,
+until a call to restart it.
+</li>
+
+<li><b>"<code>restart</code>": </b>
+Restarts automatic execution of the garbage collector.
+</li>
+
+<li><b>"<code>count</code>": </b>
+Returns the total memory in use by Lua in Kbytes.
+The value has a fractional part,
+so that it multiplied by 1024
+gives the exact number of bytes in use by Lua.
+</li>
+
+<li><b>"<code>step</code>": </b>
+Performs a garbage-collection step.
+The step "size" is controlled by <code>arg</code>.
+With a zero value,
+the collector will perform one basic (indivisible) step.
+For non-zero values,
+the collector will perform as if that amount of memory
+(in Kbytes) had been allocated by Lua.
+Returns <b>true</b> if the step finished a collection cycle.
+</li>
+
+<li><b>"<code>isrunning</code>": </b>
+Returns a boolean that tells whether the collector is running
+(i.e., not stopped).
+</li>
+
+<li><b>"<code>incremental</code>": </b>
+Change the collector mode to incremental.
+This option can be followed by three numbers:
+the garbage-collector pause,
+the step multiplier,
+and the step size (see <a href="#2.5.1">&sect;2.5.1</a>).
+A zero means to not change that value.
+</li>
+
+<li><b>"<code>generational</code>": </b>
+Change the collector mode to generational.
+This option can be followed by two numbers:
+the garbage-collector minor multiplier
+and the major multiplier (see <a href="#2.5.2">&sect;2.5.2</a>).
+A zero means to not change that value.
+</li>
+
+</ul><p>
+See <a href="#2.5">&sect;2.5</a> for more details about garbage collection
+and some of these options.
+
+
+<p>
+This function should not be called by a finalizer.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-dofile"><code>dofile ([filename])</code></a></h3>
+Opens the named file and executes its content as a Lua chunk.
+When called without arguments,
+<code>dofile</code> executes the content of the standard input (<code>stdin</code>).
+Returns all values returned by the chunk.
+In case of errors, <code>dofile</code> propagates the error
+to its caller.
+(That is, <code>dofile</code> does not run in protected mode.)
+
+
+
+
+<p>
+<hr><h3><a name="pdf-error"><code>error (message [, level])</code></a></h3>
+Raises an error (see <a href="#2.3">&sect;2.3</a>) with <code>message</code> as the error object.
+This function never returns.
+
+
+<p>
+Usually, <code>error</code> adds some information about the error position
+at the beginning of the message, if the message is a string.
+The <code>level</code> argument specifies how to get the error position.
+With level&nbsp;1 (the default), the error position is where the
+<code>error</code> function was called.
+Level&nbsp;2 points the error to where the function
+that called <code>error</code> was called; and so on.
+Passing a level&nbsp;0 avoids the addition of error position information
+to the message.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-_G"><code>_G</code></a></h3>
+A global variable (not a function) that
+holds the global environment (see <a href="#2.2">&sect;2.2</a>).
+Lua itself does not use this variable;
+changing its value does not affect any environment,
+nor vice versa.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-getmetatable"><code>getmetatable (object)</code></a></h3>
+
+
+<p>
+If <code>object</code> does not have a metatable, returns <b>nil</b>.
+Otherwise,
+if the object's metatable has a <code>__metatable</code> field,
+returns the associated value.
+Otherwise, returns the metatable of the given object.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-ipairs"><code>ipairs (t)</code></a></h3>
+
+
+<p>
+Returns three values (an iterator function, the table <code>t</code>, and 0)
+so that the construction
+
+<pre>
+     for i,v in ipairs(t) do <em>body</em> end
+</pre><p>
+will iterate over the key&ndash;value pairs
+(<code>1,t[1]</code>), (<code>2,t[2]</code>), ...,
+up to the first absent index.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-load"><code>load (chunk [, chunkname [, mode [, env]]])</code></a></h3>
+
+
+<p>
+Loads a chunk.
+
+
+<p>
+If <code>chunk</code> is a string, the chunk is this string.
+If <code>chunk</code> is a function,
+<code>load</code> calls it repeatedly to get the chunk pieces.
+Each call to <code>chunk</code> must return a string that concatenates
+with previous results.
+A return of an empty string, <b>nil</b>, or no value signals the end of the chunk.
+
+
+<p>
+If there are no syntactic errors,
+<code>load</code> returns the compiled chunk as a function;
+otherwise, it returns <b>fail</b> plus the error message.
+
+
+<p>
+When you load a main chunk,
+the resulting function will always have exactly one upvalue,
+the <code>_ENV</code> variable (see <a href="#2.2">&sect;2.2</a>).
+However,
+when you load a binary chunk created from a function (see <a href="#pdf-string.dump"><code>string.dump</code></a>),
+the resulting function can have an arbitrary number of upvalues,
+and there is no guarantee that its first upvalue will be
+the <code>_ENV</code> variable.
+(A non-main function may not even have an <code>_ENV</code> upvalue.)
+
+
+<p>
+Regardless, if the resulting function has any upvalues,
+its first upvalue is set to the value of <code>env</code>,
+if that parameter is given,
+or to the value of the global environment.
+Other upvalues are initialized with <b>nil</b>.
+All upvalues are fresh, that is,
+they are not shared with any other function.
+
+
+<p>
+<code>chunkname</code> is used as the name of the chunk for error messages
+and debug information (see <a href="#4.7">&sect;4.7</a>).
+When absent,
+it defaults to <code>chunk</code>, if <code>chunk</code> is a string,
+or to "<code>=(load)</code>" otherwise.
+
+
+<p>
+The string <code>mode</code> controls whether the chunk can be text or binary
+(that is, a precompiled chunk).
+It may be the string "<code>b</code>" (only binary chunks),
+"<code>t</code>" (only text chunks),
+or "<code>bt</code>" (both binary and text).
+The default is "<code>bt</code>".
+
+
+<p>
+It is safe to load malformed binary chunks;
+<code>load</code> signals an appropriate error.
+However,
+Lua does not check the consistency of the code inside binary chunks;
+running maliciously crafted bytecode can crash the interpreter.
+
+
+

+<hr><h3><a name="pdf-loadfile"><code>loadfile ([filename [, mode [, env]]])</code></a></h3>
+
+
+<p>
+Similar to <a href="#pdf-load"><code>load</code></a>,
+but gets the chunk from file <code>filename</code>
+or from the standard input,
+if no file name is given.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-next"><code>next (table [, index])</code></a></h3>
+
+
+<p>
+Allows a program to traverse all fields of a table.
+Its first argument is a table and its second argument
+is an index in this table.
+A call to <code>next</code> returns the next index of the table
+and its associated value.
+When called with <b>nil</b> as its second argument,
+<code>next</code> returns an initial index
+and its associated value.
+When called with the last index,
+or with <b>nil</b> in an empty table,
+<code>next</code> returns <b>nil</b>.
+If the second argument is absent, then it is interpreted as <b>nil</b>.
+In particular,
+you can use <code>next(t)</code> to check whether a table is empty.
+
+
+<p>
+The order in which the indices are enumerated is not specified,
+<em>even for numeric indices</em>.
+(To traverse a table in numerical order,
+use a numerical <b>for</b>.)
+
+
+<p>
+You should not assign any value to a non-existent field in a table
+during its traversal.
+You may however modify existing fields.
+In particular, you may set existing fields to nil.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-pairs"><code>pairs (t)</code></a></h3>
+
+
+<p>
+If <code>t</code> has a metamethod <code>__pairs</code>,
+calls it with <code>t</code> as argument and returns the first three
+results from the call.
+
+
+<p>
+Otherwise,
+returns three values: the <a href="#pdf-next"><code>next</code></a> function, the table <code>t</code>, and <b>nil</b>,
+so that the construction
+
+<pre>
+     for k,v in pairs(t) do <em>body</em> end
+</pre><p>
+will iterate over all key&ndash;value pairs of table <code>t</code>.
+
+
+<p>
+See function <a href="#pdf-next"><code>next</code></a> for the caveats of modifying
+the table during its traversal.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-pcall"><code>pcall (f [, arg1, &middot;&middot;&middot;])</code></a></h3>
+
+
+<p>
+Calls the function <code>f</code> with
+the given arguments in <em>protected mode</em>.
+This means that any error inside&nbsp;<code>f</code> is not propagated;
+instead, <code>pcall</code> catches the error
+and returns a status code.
+Its first result is the status code (a boolean),
+which is <b>true</b> if the call succeeds without errors.
+In such case, <code>pcall</code> also returns all results from the call,
+after this first result.
+In case of any error, <code>pcall</code> returns <b>false</b> plus the error object.
+Note that errors caught by <code>pcall</code> do not call a message handler.
+
+
+

+<p>
+<hr><h3><a name="pdf-print"><code>print (&middot;&middot;&middot;)</code></a></h3>
+Receives any number of arguments
+and prints their values to <code>stdout</code>,
+converting each argument to a string
+following the same rules of <a href="#pdf-tostring"><code>tostring</code></a>.
+
+
+<p>
+The function <code>print</code> is not intended for formatted output,
+but only as a quick way to show a value,

+<hr><h3><a name="pdf-rawequal"><code>rawequal (v1, v2)</code></a></h3>
+Checks whether <code>v1</code> is equal to <code>v2</code>,
+without invoking the <code>__eq</code> metamethod.
+Returns a boolean.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-rawget"><code>rawget (table, index)</code></a></h3>
+Gets the real value of <code>table[index]</code>,
+without using the <code>__index</code> metavalue.
+<code>table</code> must be a table;
+<code>index</code> may be any value.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-rawlen"><code>rawlen (v)</code></a></h3>
+Returns the length of the object <code>v</code>,

+Returns an integer.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-rawset"><code>rawset (table, index, value)</code></a></h3>
+Sets the real value of <code>table[index]</code> to <code>value</code>,
+without using the <code>__newindex</code> metavalue.
+<code>table</code> must be a table,
+<code>index</code> any value different from <b>nil</b> and NaN,
+and <code>value</code> any Lua value.
+
+
+<p>
+This function returns <code>table</code>.
+

+<p>
+<hr><h3><a name="pdf-select"><code>select (index, &middot;&middot;&middot;)</code></a></h3>
+
+
+<p>
+If <code>index</code> is a number,
+returns all arguments after argument number <code>index</code>;
+a negative number indexes from the end (-1 is the last argument).
+Otherwise, <code>index</code> must be the string <code>"#"</code>,
+and <code>select</code> returns the total number of extra arguments it received.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-setmetatable"><code>setmetatable (table, metatable)</code></a></h3>
+
+
+<p>
+Sets the metatable for the given table.
+If <code>metatable</code> is <b>nil</b>,
+removes the metatable of the given table.
+If the original metatable has a <code>__metatable</code> field,
+raises an error.
+
+
+<p>
+This function returns <code>table</code>.
+
+
+<p>
+To change the metatable of other types from Lua code,
+you must use the debug library (<a href="#6.10">&sect;6.10</a>).
+
+
+
+
+<p>
+<hr><h3><a name="pdf-tonumber"><code>tonumber (e [, base])</code></a></h3>
+
+
+<p>
+When called with no <code>base</code>,
+<code>tonumber</code> tries to convert its argument to a number.
+If the argument is already a number or
+a string convertible to a number,
+then <code>tonumber</code> returns this number;
+otherwise, it returns <b>fail</b>.
+
+
+<p>
+The conversion of strings can result in integers or floats,
+according to the lexical conventions of Lua (see <a href="#3.1">&sect;3.1</a>).
+The string may have leading and trailing spaces and a sign.
+
+
+<p>
+When called with <code>base</code>,
+then <code>e</code> must be a string to be interpreted as
+an integer numeral in that base.
+The base may be any integer between 2 and 36, inclusive.
+In bases above&nbsp;10, the letter '<code>A</code>' (in either upper or lower case)
+represents&nbsp;10, '<code>B</code>' represents&nbsp;11, and so forth,
+with '<code>Z</code>' representing 35.
+If the string <code>e</code> is not a valid numeral in the given base,
+the function returns <b>fail</b>.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-tostring"><code>tostring (v)</code></a></h3>
+
+
+<p>
+Receives a value of any type and
+converts it to a string in a human-readable format.
+
+
+<p>
+If the metatable of <code>v</code> has a <code>__tostring</code> field,
+then <code>tostring</code> calls the corresponding value
+with <code>v</code> as argument,
+and uses the result of the call as its result.
+Otherwise, if the metatable of <code>v</code> has a <code>__name</code> field
+with a string value,
+<code>tostring</code> may use that string in its final result.
+

+<hr><h3><a name="pdf-_VERSION"><code>_VERSION</code></a></h3>
+
+
+<p>
+A global variable (not a function) that
+holds a string containing the running Lua version.
+The current value of this variable is "<code>Lua 5.4</code>".
+
+
+
+
+<p>
+<hr><h3><a name="pdf-warn"><code>warn (msg1, &middot;&middot;&middot;)</code></a></h3>
+
+
+<p>
+Emits a warning with a message composed by the concatenation
+of all its arguments (which should be strings).
+
+
+<p>
+By convention,
+a one-piece message starting with '<code>@</code>'
+is intended to be a <em>control message</em>,
+which is a message to the warning system itself.
+In particular, the standard warning function in Lua
+recognizes the control messages "<code>@off</code>",
+to stop the emission of warnings,
+and "<code>@on</code>", to (re)start the emission;
+it ignores unknown control messages.
+
+

+Starts or continues the execution of coroutine <code>co</code>.
+The first time you resume a coroutine,
+it starts running its body.
+The values <code>val1</code>, ... are passed

+<p>
+If the coroutine runs without any errors,
+<code>resume</code> returns <b>true</b> plus any values passed to <code>yield</code>
+(when the coroutine yields) or any values returned by the body function
+(when the coroutine terminates).

+
+<h2>6.3 &ndash; <a name="6.3">Modules</a></h2>
+
+<p>
+The package library provides basic
+facilities for loading modules in Lua.
+It exports one function directly in the global environment:
+<a href="#pdf-require"><code>require</code></a>.
+Everything else is exported in the table <a name="pdf-package"><code>package</code></a>.
+
+
+<p>
+<hr><h3><a name="pdf-require"><code>require (modname)</code></a></h3>
+
+
+<p>
+Loads the given module.
+The function starts by looking into the <a href="#pdf-package.loaded"><code>package.loaded</code></a> table
+to determine whether <code>modname</code> is already loaded.
+If it is, then <code>require</code> returns the value stored
+at <code>package.loaded[modname]</code>.
+(The absence of a second result in this case
+signals that this call did not have to load the module.)
+Otherwise, it tries to find a <em>loader</em> for the module.
+
+
+<p>
+To find a loader,
+<code>require</code> is guided by the table <a href="#pdf-package.searchers"><code>package.searchers</code></a>.
+Each item in this table is a search function,
+that searches for the module in a particular way.
+By changing this table,
+we can change how <code>require</code> looks for a module.
+The following explanation is based on the default configuration
+for <a href="#pdf-package.searchers"><code>package.searchers</code></a>.
+
+
+<p>
+First <code>require</code> queries <code>package.preload[modname]</code>.
+If it has a value,
+this value (which must be a function) is the loader.
+Otherwise <code>require</code> searches for a Lua loader using the
+path stored in <a href="#pdf-package.path"><code>package.path</code></a>.
+If that also fails, it searches for a C&nbsp;loader using the
+path stored in <a href="#pdf-package.cpath"><code>package.cpath</code></a>.
+If that also fails,
+it tries an <em>all-in-one</em> loader (see <a href="#pdf-package.searchers"><code>package.searchers</code></a>).
+
+
+<p>
+Once a loader is found,
+<code>require</code> calls the loader with two arguments:
+<code>modname</code> and an extra value,
+a <em>loader data</em>,
+also returned by the searcher.
+The loader data can be any value useful to the module;
+for the default searchers,
+it indicates where the loader was found.
+(For instance, if the loader came from a file,
+this extra value is the file path.)
+If the loader returns any non-nil value,

+
+
+<p>
+Dynamically links the host program with the C&nbsp;library <code>libname</code>.
+
+
+<p>
+If <code>funcname</code> is "<code>*</code>",
+then it only links with the library,
+making the symbols exported by the library
+available to other dynamically linked libraries.
+Otherwise,
+it looks for a function <code>funcname</code> inside the library
+and returns this function as a C&nbsp;function.
+So, <code>funcname</code> must follow the <a href="#lua_CFunction"><code>lua_CFunction</code></a> prototype
+(see <a href="#lua_CFunction"><code>lua_CFunction</code></a>).
+
+
+<p>
+This is a low-level function.
+It completely bypasses the package and module system.
+Unlike <a href="#pdf-require"><code>require</code></a>,
+it does not perform any path searching and
+does not automatically adds extensions.
+<code>libname</code> must be the complete file name of the C&nbsp;library,
+including if necessary a path and an extension.
+<code>funcname</code> must be the exact name exported by the C&nbsp;library
+(which may depend on the C&nbsp;compiler and linker used).
+
+
+<p>
+This functionality is not supported by ISO&nbsp;C.
+As such, it is only available on some platforms
+(Windows, Linux, Mac OS X, Solaris, BSD,
+plus other Unix systems that support the <code>dlfcn</code> standard).
+
+
+<p>
+This function is inherently insecure,
+as it allows Lua to call any function in any readable dynamic
+library in the system.
+(Lua calls any function assuming the function
+has a proper prototype and respects a proper protocol
+(see <a href="#lua_CFunction"><code>lua_CFunction</code></a>).
+Therefore,
+calling an arbitrary function in an arbitrary dynamic library
+more often than not results in an access violation.)

+This variable is only a reference to the real table;

+table used by <a href="#pdf-require"><code>require</code></a>.
+The real table is stored in the C registry (see <a href="#4.3">&sect;4.3</a>),

+<hr><h3><a name="pdf-package.searchers"><code>package.searchers</code></a></h3>
+
+
+<p>
+A table used by <a href="#pdf-require"><code>require</code></a> to control how to find modules.
+
+
+<p>
+Each entry in this table is a <em>searcher function</em>.
+When looking for a module,
+<a href="#pdf-require"><code>require</code></a> calls each of these searchers in ascending order,
+with the module name (the argument given to <a href="#pdf-require"><code>require</code></a>) as its
+sole argument.
+If the searcher finds the module,
+it returns another function, the module <em>loader</em>,
+plus an extra value, a <em>loader data</em>,
+that will be passed to that loader and
+returned as a second result by <a href="#pdf-require"><code>require</code></a>.
+If it cannot find the module,
+it returns a string explaining why
+(or <b>nil</b> if it has nothing to say).
+
+
+<p>
+Lua initializes this table with four searcher functions.
+
+
+<p>
+The first searcher simply looks for a loader in the
+<a href="#pdf-package.preload"><code>package.preload</code></a> table.
+
+
+<p>
+The second searcher looks for a loader as a Lua library,
+using the path stored at <a href="#pdf-package.path"><code>package.path</code></a>.
+The search is done as described in function <a href="#pdf-package.searchpath"><code>package.searchpath</code></a>.
+
+
+<p>
+The third searcher looks for a loader as a C&nbsp;library,
+using the path given by the variable <a href="#pdf-package.cpath"><code>package.cpath</code></a>.
+Again,
+the search is done as described in function <a href="#pdf-package.searchpath"><code>package.searchpath</code></a>.
+For instance,
+if the C&nbsp;path is the string
+
+<pre>
+     "./?.so;./?.dll;/usr/local/?/init.so"
+</pre><p>
+the searcher for module <code>foo</code>
+will try to open the files <code>./foo.so</code>, <code>./foo.dll</code>,
+and <code>/usr/local/foo/init.so</code>, in that order.
+Once it finds a C&nbsp;library,
+this searcher first uses a dynamic link facility to link the
+application with the library.
+Then it tries to find a C&nbsp;function inside the library to
+be used as the loader.
+The name of this C&nbsp;function is the string "<code>luaopen_</code>"
+concatenated with a copy of the module name where each dot
+is replaced by an underscore.
+Moreover, if the module name has a hyphen,
+its suffix after (and including) the first hyphen is removed.
+For instance, if the module name is <code>a.b.c-v2.1</code>,
+the function name will be <code>luaopen_a_b_c</code>.
+
+
+<p>
+The fourth searcher tries an <em>all-in-one loader</em>.
+It searches the C&nbsp;path for a library for
+the root name of the given module.
+For instance, when requiring <code>a.b.c</code>,
+it will search for a C&nbsp;library for <code>a</code>.
+If found, it looks into it for an open function for
+the submodule;
+in our example, that would be <code>luaopen_a_b_c</code>.
+With this facility, a package can pack several C&nbsp;submodules
+into one single library,
+with each submodule keeping its original open function.
+
+
+<p>
+All searchers except the first one (preload) return as the extra value
+the file path where the module was found,
+as returned by <a href="#pdf-package.searchpath"><code>package.searchpath</code></a>.
+The first searcher always returns the string "<code>:preload:</code>".
+
+
+<p>
+Searchers should raise no errors and have no side effects in Lua.
+(They may have side effects in C,
+for instance by linking the application with a library.)
+
+
+
+
+<p>
+<hr><h3><a name="pdf-package.searchpath"><code>package.searchpath (name, path [, sep [, rep]])</code></a></h3>
+
+
+<p>
+Searches for the given <code>name</code> in the given <code>path</code>.
+
+
+<p>
+A path is a string containing a sequence of
+<em>templates</em> separated by semicolons.
+For each template,
+the function replaces each interrogation mark (if any)
+in the template with a copy of <code>name</code>
+wherein all occurrences of <code>sep</code>
+(a dot, by default)
+were replaced by <code>rep</code>
+(the system's directory separator, by default),
+and then tries to open the resulting file name.
+
+
+<p>
+For instance, if the path is the string
+
+<pre>
+     "./?.lua;./?.lc;/usr/local/?/init.lua"
+</pre><p>
+the search for the name <code>foo.a</code>
+will try to open the files
+<code>./foo/a.lua</code>, <code>./foo/a.lc</code>, and
+<code>/usr/local/foo/a/init.lua</code>, in that order.
+
+
+<p>
+Returns the resulting name of the first file that it can
+open in read mode (after closing the file),
+or <b>fail</b> plus an error message if none succeeds.
+(This error message lists all file names it tried to open.)
+
+
+

+
+
+<h2>6.4 &ndash; <a name="6.4">String Manipulation</a></h2>
+
+
+
+<p>
+This library provides generic functions for string manipulation,
+such as finding and extracting substrings, and pattern matching.
+When indexing a string in Lua, the first character is at position&nbsp;1
+(not at&nbsp;0, as in C).
+Indices are allowed to be negative and are interpreted as indexing backwards,
+from the end of the string.
+Thus, the last character is at position -1, and so on.
+
+
+<p>
+The string library provides all its functions inside the table
+<a name="pdf-string"><code>string</code></a>.
+It also sets a metatable for strings
+where the <code>__index</code> field points to the <code>string</code> table.
+Therefore, you can use the string functions in object-oriented style.
+For instance, <code>string.byte(s,i)</code>
+can be written as <code>s:byte(i)</code>.
+
+
+<p>
+The string library assumes one-byte character encodings.
+
+
+<p>
+<hr><h3><a name="pdf-string.byte"><code>string.byte (s [, i [, j]])</code></a></h3>
+Returns the internal numeric codes of the characters <code>s[i]</code>,
+<code>s[i+1]</code>, ..., <code>s[j]</code>.
+The default value for <code>i</code> is&nbsp;1;
+the default value for <code>j</code> is&nbsp;<code>i</code>.
+These indices are corrected
+following the same rules of function <a href="#pdf-string.sub"><code>string.sub</code></a>.
+
+
+<p>
+Numeric codes are not necessarily portable across platforms.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-string.char"><code>string.char (&middot;&middot;&middot;)</code></a></h3>
+Receives zero or more integers.
+Returns a string with length equal to the number of arguments,
+in which each character has the internal numeric code equal
+to its corresponding argument.
+
+
+<p>
+Numeric codes are not necessarily portable across platforms.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-string.dump"><code>string.dump (function [, strip])</code></a></h3>
+
+
+<p>
+Returns a string containing a binary representation
+(a <em>binary chunk</em>)
+of the given function,
+so that a later <a href="#pdf-load"><code>load</code></a> on this string returns
+a copy of the function (but with new upvalues).
+If <code>strip</code> is a true value,
+the binary representation may not include all debug information
+about the function,
+to save space.
+
+
+<p>
+Functions with upvalues have only their number of upvalues saved.
+When (re)loaded,
+those upvalues receive fresh instances.
+(See the <a href="#pdf-load"><code>load</code></a> function for details about
+how these upvalues are initialized.
+You can use the debug library to serialize
+and reload the upvalues of a function
+in a way adequate to your needs.)
+
+
+
+
+<p>
+<hr><h3><a name="pdf-string.find"><code>string.find (s, pattern [, init [, plain]])</code></a></h3>
+
+
+<p>
+Looks for the first match of
+<code>pattern</code> (see <a href="#6.4.1">&sect;6.4.1</a>) in the string <code>s</code>.
+If it finds a match, then <code>find</code> returns the indices of&nbsp;<code>s</code>
+where this occurrence starts and ends;
+otherwise, it returns <b>fail</b>.
+A third, optional numeric argument <code>init</code> specifies
+where to start the search;
+its default value is&nbsp;1 and can be negative.
+A <b>true</b> as a fourth, optional argument <code>plain</code>
+turns off the pattern matching facilities,
+so the function does a plain "find substring" operation,
+with no characters in <code>pattern</code> being considered magic.
+
+
+<p>
+If the pattern has captures,
+then in a successful match
+the captured values are also returned,
+after the two indices.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-string.format"><code>string.format (formatstring, &middot;&middot;&middot;)</code></a></h3>
+
+
+<p>
+Returns a formatted version of its variable number of arguments
+following the description given in its first argument,
+which must be a string.
+The format string follows the same rules as the ISO&nbsp;C function <code>sprintf</code>.
+The only differences are that the conversion specifiers and modifiers
+<code>F</code>, <code>n</code>, <code>*</code>, <code>h</code>, <code>L</code>, and <code>l</code> are not supported
+and that there is an extra specifier, <code>q</code>.
+Both width and precision, when present,
+are limited to two digits.
+
+
+<p>
+The specifier <code>q</code> formats booleans, nil, numbers, and strings
+in a way that the result is a valid constant in Lua source code.
+Booleans and nil are written in the obvious way
+(<code>true</code>, <code>false</code>, <code>nil</code>).
+Floats are written in hexadecimal,
+to preserve full precision.
+A string is written between double quotes,
+using escape sequences when necessary to ensure that
+it can safely be read back by the Lua interpreter.
+For instance, the call
+
+<pre>
+     string.format('%q', 'a string with "quotes" and \n new line')
+</pre><p>
+may produce the string:
+
+<pre>
+     "a string with \"quotes\" and \
+      new line"
+</pre><p>
+This specifier does not support modifiers (flags, width, precision).
+
+
+<p>
+The conversion specifiers
+<code>A</code>, <code>a</code>, <code>E</code>, <code>e</code>, <code>f</code>,
+<code>G</code>, and <code>g</code> all expect a number as argument.
+The specifiers <code>c</code>, <code>d</code>,
+<code>i</code>, <code>o</code>, <code>u</code>, <code>X</code>, and <code>x</code>
+expect an integer.
+When Lua is compiled with a C89 compiler,
+the specifiers <code>A</code> and <code>a</code> (hexadecimal floats)
+do not support modifiers.
+
+
+<p>
+The specifier <code>s</code> expects a string;
+if its argument is not a string,
+it is converted to one following the same rules of <a href="#pdf-tostring"><code>tostring</code></a>.
+If the specifier has any modifier,
+the corresponding string argument should not contain embedded zeros.
+
+
+<p>
+The specifier <code>p</code> formats the pointer
+returned by <a href="#lua_topointer"><code>lua_topointer</code></a>.
+That gives a unique string identifier for tables, userdata,
+threads, strings, and functions.
+For other values (numbers, nil, booleans),
+this specifier results in a string representing
+the pointer <code>NULL</code>.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-string.gmatch"><code>string.gmatch (s, pattern [, init])</code></a></h3>
+Returns an iterator function that,
+each time it is called,
+returns the next captures from <code>pattern</code> (see <a href="#6.4.1">&sect;6.4.1</a>)
+over the string <code>s</code>.
+If <code>pattern</code> specifies no captures,
+then the whole match is produced in each call.
+A third, optional numeric argument <code>init</code> specifies
+where to start the search;
+its default value is&nbsp;1 and can be negative.
+
+
+<p>
+As an example, the following loop
+will iterate over all the words from string <code>s</code>,
+printing one per line:
+
+<pre>
+     s = "hello world from Lua"
+     for w in string.gmatch(s, "%a+") do
+       print(w)
+     end
+</pre><p>
+The next example collects all pairs <code>key=value</code> from the
+given string into a table:
+
+<pre>
+     t = {}
+     s = "from=world, to=Lua"
+     for k, v in string.gmatch(s, "(%w+)=(%w+)") do
+       t[k] = v
+     end
+</pre>
+
+<p>
+For this function, a caret '<code>^</code>' at the start of a pattern does not
+work as an anchor, as this would prevent the iteration.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-string.gsub"><code>string.gsub (s, pattern, repl [, n])</code></a></h3>
+Returns a copy of <code>s</code>
+in which all (or the first <code>n</code>, if given)
+occurrences of the <code>pattern</code> (see <a href="#6.4.1">&sect;6.4.1</a>) have been
+replaced by a replacement string specified by <code>repl</code>,
+which can be a string, a table, or a function.
+<code>gsub</code> also returns, as its second value,
+the total number of matches that occurred.
+The name <code>gsub</code> comes from <em>Global SUBstitution</em>.
+
+
+<p>
+If <code>repl</code> is a string, then its value is used for replacement.
+The character&nbsp;<code>%</code> works as an escape character:
+any sequence in <code>repl</code> of the form <code>%<em>d</em></code>,
+with <em>d</em> between 1 and 9,
+stands for the value of the <em>d</em>-th captured substring;
+the sequence <code>%0</code> stands for the whole match;
+the sequence <code>%%</code> stands for a single&nbsp;<code>%</code>.
+
+
+<p>
+If <code>repl</code> is a table, then the table is queried for every match,
+using the first capture as the key.
+
+
+<p>
+If <code>repl</code> is a function, then this function is called every time a
+match occurs, with all captured substrings passed as arguments,
+in order.
+
+
+<p>
+In any case,
+if the pattern specifies no captures,
+then it behaves as if the whole pattern was inside a capture.
+
+
+<p>
+If the value returned by the table query or by the function call
+is a string or a number,
+then it is used as the replacement string;
+otherwise, if it is <b>false</b> or <b>nil</b>,
+then there is no replacement
+(that is, the original match is kept in the string).
+
+
+<p>
+Here are some examples:
+
+<pre>
+     x = string.gsub("hello world", "(%w+)", "%1 %1")
+     --&gt; x="hello hello world world"
+     
+     x = string.gsub("hello world", "%w+", "%0 %0", 1)
+     --&gt; x="hello hello world"
+     
+     x = string.gsub("hello world from Lua", "(%w+)%s*(%w+)", "%2 %1")
+     --&gt; x="world hello Lua from"
+     
+     x = string.gsub("home = $HOME, user = $USER", "%$(%w+)", os.getenv)
+     --&gt; x="home = /home/roberto, user = roberto"
+     
+     x = string.gsub("4+5 = $return 4+5$", "%$(.-)%$", function (s)
+           return load(s)()
+         end)
+     --&gt; x="4+5 = 9"
+     
+     local t = {name="lua", version="5.4"}

+<code>i</code> and <code>j</code> can be negative.
+If <code>j</code> is absent, then it is assumed to be equal to -1
+(which is the same as the string length).
+In particular,
+the call <code>string.sub(s,1,j)</code> returns a prefix of <code>s</code>
+with length <code>j</code>,
+and <code>string.sub(s, -i)</code> (for a positive <code>i</code>)
+returns a suffix of <code>s</code>
+with length <code>i</code>.
+
+
+<p>
+If, after the translation of negative indices,
+<code>i</code> is less than 1,
+it is corrected to 1.
+If <code>j</code> is greater than the string length,
+it is corrected to that length.
+If, after these corrections,
+<code>i</code> is greater than <code>j</code>,
+the function returns the empty string.

+according to the format string <code>fmt</code> (see <a href="#6.4.2">&sect;6.4.2</a>).
+An optional <code>pos</code> marks where

+
+<h3>6.4.1 &ndash; <a name="6.4.1">Patterns</a></h3>
+
+
+
+<p>
+Patterns in Lua are described by regular strings,
+which are interpreted as patterns by the pattern-matching functions
+<a href="#pdf-string.find"><code>string.find</code></a>,
+<a href="#pdf-string.gmatch"><code>string.gmatch</code></a>,
+<a href="#pdf-string.gsub"><code>string.gsub</code></a>,
+and <a href="#pdf-string.match"><code>string.match</code></a>.
+This section describes the syntax and the meaning
+(that is, what they match) of these strings.
+
+
+
+
+
+<h4>Character Class:</h4><p>
+A <em>character class</em> is used to represent a set of characters.
+The following combinations are allowed in describing a character class:
+
+<ul>
+
+<li><b><em>x</em>: </b>
+(where <em>x</em> is not one of the <em>magic characters</em>
+<code>^$()%.[]*+-?</code>)
+represents the character <em>x</em> itself.
+</li>
+
+<li><b><code>.</code>: </b> (a dot) represents all characters.</li>
+
+<li><b><code>%a</code>: </b> represents all letters.</li>
+
+<li><b><code>%c</code>: </b> represents all control characters.</li>
+
+<li><b><code>%d</code>: </b> represents all digits.</li>
+
+<li><b><code>%g</code>: </b> represents all printable characters except space.</li>
+
+<li><b><code>%l</code>: </b> represents all lowercase letters.</li>
+
+<li><b><code>%p</code>: </b> represents all punctuation characters.</li>
+
+<li><b><code>%s</code>: </b> represents all space characters.</li>
+
+<li><b><code>%u</code>: </b> represents all uppercase letters.</li>
+
+<li><b><code>%w</code>: </b> represents all alphanumeric characters.</li>
+
+<li><b><code>%x</code>: </b> represents all hexadecimal digits.</li>
+
+<li><b><code>%<em>x</em></code>: </b> (where <em>x</em> is any non-alphanumeric character)
+represents the character <em>x</em>.
+This is the standard way to escape the magic characters.
+Any non-alphanumeric character
+(including all punctuation characters, even the non-magical)
+can be preceded by a '<code>%</code>' to represent itself in a pattern.
+</li>
+
+<li><b><code>[<em>set</em>]</code>: </b>
+represents the class which is the union of all
+characters in <em>set</em>.
+A range of characters can be specified by
+separating the end characters of the range,
+in ascending order, with a '<code>-</code>'.
+All classes <code>%</code><em>x</em> described above can also be used as
+components in <em>set</em>.
+All other characters in <em>set</em> represent themselves.
+For example, <code>[%w_]</code> (or <code>[_%w]</code>)
+represents all alphanumeric characters plus the underscore,
+<code>[0-7]</code> represents the octal digits,
+and <code>[0-7%l%-]</code> represents the octal digits plus
+the lowercase letters plus the '<code>-</code>' character.
+
+
+<p>
+You can put a closing square bracket in a set
+by positioning it as the first character in the set.
+You can put a hyphen in a set
+by positioning it as the first or the last character in the set.
+(You can also use an escape for both cases.)
+
+
+<p>
+The interaction between ranges and classes is not defined.
+Therefore, patterns like <code>[%a-z]</code> or <code>[a-%%]</code>
+have no meaning.
+</li>
+
+<li><b><code>[^<em>set</em>]</code>: </b>
+represents the complement of <em>set</em>,
+where <em>set</em> is interpreted as above.
+</li>
+
+</ul><p>
+For all classes represented by single letters (<code>%a</code>, <code>%c</code>, etc.),
+the corresponding uppercase letter represents the complement of the class.
+For instance, <code>%S</code> represents all non-space characters.
+
+
+<p>
+The definitions of letter, space, and other character groups
+depend on the current locale.
+In particular, the class <code>[a-z]</code> may not be equivalent to <code>%l</code>.
+
+
+
+
+
+<h4>Pattern Item:</h4><p>
+A <em>pattern item</em> can be
+
+<ul>
+
+<li>
+a single character class,
+which matches any single character in the class;
+</li>
+
+<li>
+a single character class followed by '<code>*</code>',
+which matches sequences of zero or more characters in the class.
+These repetition items will always match the longest possible sequence;
+</li>
+
+<li>
+a single character class followed by '<code>+</code>',
+which matches sequences of one or more characters in the class.
+These repetition items will always match the longest possible sequence;
+</li>
+
+<li>
+a single character class followed by '<code>-</code>',
+which also matches sequences of zero or more characters in the class.
+Unlike '<code>*</code>',
+these repetition items will always match the shortest possible sequence;
+</li>
+
+<li>
+a single character class followed by '<code>?</code>',
+which matches zero or one occurrence of a character in the class.
+It always matches one occurrence if possible;
+</li>
+
+<li>
+<code>%<em>n</em></code>, for <em>n</em> between 1 and 9;
+such item matches a substring equal to the <em>n</em>-th captured string
+(see below);
+</li>
+
+<li>
+<code>%b<em>xy</em></code>, where <em>x</em> and <em>y</em> are two distinct characters;
+such item matches strings that start with&nbsp;<em>x</em>, end with&nbsp;<em>y</em>,
+and where the <em>x</em> and <em>y</em> are <em>balanced</em>.
+This means that, if one reads the string from left to right,
+counting <em>+1</em> for an <em>x</em> and <em>-1</em> for a <em>y</em>,
+the ending <em>y</em> is the first <em>y</em> where the count reaches 0.
+For instance, the item <code>%b()</code> matches expressions with
+balanced parentheses.
+</li>
+
+<li>
+<code>%f[<em>set</em>]</code>, a <em>frontier pattern</em>;
+such item matches an empty string at any position such that
+the next character belongs to <em>set</em>
+and the previous character does not belong to <em>set</em>.
+The set <em>set</em> is interpreted as previously described.
+The beginning and the end of the subject are handled as if
+they were the character '<code>\0</code>'.
+</li>
+
+</ul>
+
+
+
+
+<h4>Pattern:</h4><p>
+A <em>pattern</em> is a sequence of pattern items.
+A caret '<code>^</code>' at the beginning of a pattern anchors the match at the
+beginning of the subject string.
+A '<code>$</code>' at the end of a pattern anchors the match at the
+end of the subject string.
+At other positions,
+'<code>^</code>' and '<code>$</code>' have no special meaning and represent themselves.
+
+
+
+
+
+<h4>Captures:</h4><p>
+A pattern can contain sub-patterns enclosed in parentheses;
+they describe <em>captures</em>.
+When a match succeeds, the substrings of the subject string
+that match captures are stored (<em>captured</em>) for future use.
+Captures are numbered according to their left parentheses.
+For instance, in the pattern <code>"(a*(.)%w(%s*))"</code>,
+the part of the string matching <code>"a*(.)%w(%s*)"</code> is
+stored as the first capture, and therefore has number&nbsp;1;
+the character matching "<code>.</code>" is captured with number&nbsp;2,
+and the part matching "<code>%s*</code>" has number&nbsp;3.
+
+
+<p>
+As a special case, the capture <code>()</code> captures
+the current string position (a number).
+For instance, if we apply the pattern <code>"()aa()"</code> on the
+string <code>"flaaap"</code>, there will be two captures: 3&nbsp;and&nbsp;5.
+
+
+
+
+
+<h4>Multiple matches:</h4><p>
+The function <a href="#pdf-string.gsub"><code>string.gsub</code></a> and the iterator <a href="#pdf-string.gmatch"><code>string.gmatch</code></a>
+match multiple occurrences of the given pattern in the subject.
+For these functions,
+a new match is considered valid only
+if it ends at least one byte after the end of the previous match.
+In other words, the pattern machine never accepts the
+empty string as a match immediately after another match.
+As an example,
+consider the results of the following code:
+
+<pre>
+     &gt; string.gsub("abc", "()a*()", print);
+     --&gt; 1   2
+     --&gt; 3   3
+     --&gt; 4   4
+</pre><p>
+The second and third results come from Lua matching an empty
+string after '<code>b</code>' and another one after '<code>c</code>'.
+Lua does not match an empty string after '<code>a</code>',
+because it would end at the same position of the previous match.
+
+
+
+
+
+
+
+<h3>6.4.2 &ndash; <a name="6.4.2">Format Strings for Pack and Unpack</a></h3>
+
+<p>
+The first argument to <a href="#pdf-string.pack"><code>string.pack</code></a>,
+<a href="#pdf-string.packsize"><code>string.packsize</code></a>, and <a href="#pdf-string.unpack"><code>string.unpack</code></a>
+is a format string,
+which describes the layout of the structure being created or read.
+
+
+<p>
+A format string is a sequence of conversion options.
+The conversion options are as follows:
+
+<ul>
+<li><b><code>&lt;</code>: </b>sets little endian</li>
+<li><b><code>&gt;</code>: </b>sets big endian</li>
+<li><b><code>=</code>: </b>sets native endian</li>
+<li><b><code>![<em>n</em>]</code>: </b>sets maximum alignment to <code>n</code>
+(default is native alignment)</li>
+<li><b><code>b</code>: </b>a signed byte (<code>char</code>)</li>
+<li><b><code>B</code>: </b>an unsigned byte (<code>char</code>)</li>
+<li><b><code>h</code>: </b>a signed <code>short</code> (native size)</li>
+<li><b><code>H</code>: </b>an unsigned <code>short</code> (native size)</li>
+<li><b><code>l</code>: </b>a signed <code>long</code> (native size)</li>
+<li><b><code>L</code>: </b>an unsigned <code>long</code> (native size)</li>
+<li><b><code>j</code>: </b>a <code>lua_Integer</code></li>
+<li><b><code>J</code>: </b>a <code>lua_Unsigned</code></li>
+<li><b><code>T</code>: </b>a <code>size_t</code> (native size)</li>
+<li><b><code>i[<em>n</em>]</code>: </b>a signed <code>int</code> with <code>n</code> bytes
+(default is native size)</li>
+<li><b><code>I[<em>n</em>]</code>: </b>an unsigned <code>int</code> with <code>n</code> bytes
+(default is native size)</li>
+<li><b><code>f</code>: </b>a <code>float</code> (native size)</li>
+<li><b><code>d</code>: </b>a <code>double</code> (native size)</li>
+<li><b><code>n</code>: </b>a <code>lua_Number</code></li>
+<li><b><code>c<em>n</em></code>: </b>a fixed-sized string with <code>n</code> bytes</li>
+<li><b><code>z</code>: </b>a zero-terminated string</li>
+<li><b><code>s[<em>n</em>]</code>: </b>a string preceded by its length
+coded as an unsigned integer with <code>n</code> bytes
+(default is a <code>size_t</code>)</li>
+<li><b><code>x</code>: </b>one byte of padding</li>
+<li><b><code>X<em>op</em></code>: </b>an empty item that aligns
+according to option <code>op</code>
+(which is otherwise ignored)</li>
+<li><b>'<code> </code>': </b>(space) ignored</li>
+</ul><p>
+(A "<code>[<em>n</em>]</code>" means an optional integral numeral.)
+Except for padding, spaces, and configurations
+(options "<code>xX &lt;=&gt;!</code>"),
+each option corresponds to an argument in <a href="#pdf-string.pack"><code>string.pack</code></a>
+or a result in <a href="#pdf-string.unpack"><code>string.unpack</code></a>.
+
+
+<p>
+For options "<code>!<em>n</em></code>", "<code>s<em>n</em></code>", "<code>i<em>n</em></code>", and "<code>I<em>n</em></code>",
+<code>n</code> can be any integer between 1 and 16.
+All integral options check overflows;
+<a href="#pdf-string.pack"><code>string.pack</code></a> checks whether the given value fits in the given size;
+<a href="#pdf-string.unpack"><code>string.unpack</code></a> checks whether the read value fits in a Lua integer.
+For the unsigned options,
+Lua integers are treated as unsigned values too.
+
+
+<p>
+Any format string starts as if prefixed by "<code>!1=</code>",
+that is,
+with maximum alignment of 1 (no alignment)
+and native endianness.
+
+
+<p>
+Native endianness assumes that the whole system is
+either big or little endian.
+The packing functions will not emulate correctly the behavior
+of mixed-endian formats.
+
+
+<p>
+Alignment works as follows:
+For each option,
+the format gets extra padding until the data starts
+at an offset that is a multiple of the minimum between the
+option size and the maximum alignment;
+this minimum must be a power of 2.
+Options "<code>c</code>" and "<code>z</code>" are not aligned;
+option "<code>s</code>" follows the alignment of its starting integer.
+
+
+<p>
+All padding is filled with zeros by <a href="#pdf-string.pack"><code>string.pack</code></a>
+and ignored by <a href="#pdf-string.unpack"><code>string.unpack</code></a>.

+
+<h2>6.5 &ndash; <a name="6.5">UTF-8 Support</a></h2>
+
+<p>
+This library provides basic support for UTF-8 encoding.
+It provides all its functions inside the table <a name="pdf-utf8"><code>utf8</code></a>.
+This library does not provide any support for Unicode other
+than the handling of the encoding.
+Any operation that needs the meaning of a character,
+such as character classification, is outside its scope.
+
+
+<p>
+Unless stated otherwise,
+all functions that expect a byte position as a parameter
+assume that the given position is either the start of a byte sequence
+or one plus the length of the subject string.
+As in the string library,
+negative indices count from the end of the string.
+
+
+<p>
+Functions that create byte sequences
+accept all values up to <code>0x7FFFFFFF</code>,
+as defined in the original UTF-8 specification;
+that implies byte sequences of up to six bytes.
+
+
+<p>
+Functions that interpret byte sequences only accept
+valid sequences (well formed and not overlong).
+By default, they only accept byte sequences
+that result in valid Unicode code points,
+rejecting values greater than <code>10FFFF</code> and surrogates.
+A boolean argument <code>lax</code>, when available,
+lifts these checks,
+so that all values up to <code>0x7FFFFFFF</code> are accepted.
+(Not well formed and overlong sequences are still rejected.)
+
+
+<p>
+<hr><h3><a name="pdf-utf8.char"><code>utf8.char (&middot;&middot;&middot;)</code></a></h3>
+
+
+<p>
+Receives zero or more integers,
+converts each one to its corresponding UTF-8 byte sequence
+and returns a string with the concatenation of all these sequences.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-utf8.charpattern"><code>utf8.charpattern</code></a></h3>
+
+
+<p>
+The pattern (a string, not a function) "<code>[\0-\x7F\xC2-\xFD][\x80-\xBF]*</code>"
+(see <a href="#6.4.1">&sect;6.4.1</a>),
+which matches exactly one UTF-8 byte sequence,
+assuming that the subject is a valid UTF-8 string.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-utf8.codes"><code>utf8.codes (s [, lax])</code></a></h3>
+
+
+<p>
+Returns values so that the construction
+
+<pre>
+     for p, c in utf8.codes(s) do <em>body</em> end
+</pre><p>
+will iterate over all UTF-8 characters in string <code>s</code>,
+with <code>p</code> being the position (in bytes) and <code>c</code> the code point
+of each character.
+It raises an error if it meets any invalid byte sequence.

+
+
+<p>
+<hr><h3><a name="pdf-utf8.codepoint"><code>utf8.codepoint (s [, i [, j [, lax]]])</code></a></h3>
+
+
+<p>
+Returns the code points (as integers) from all characters in <code>s</code>
+that start between byte position <code>i</code> and <code>j</code> (both included).
+The default for <code>i</code> is 1 and for <code>j</code> is <code>i</code>.
+It raises an error if it meets any invalid byte sequence.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-utf8.len"><code>utf8.len (s [, i [, j [, lax]]])</code></a></h3>
+
+
+<p>
+Returns the number of UTF-8 characters in string <code>s</code>
+that start between positions <code>i</code> and <code>j</code> (both inclusive).
+The default for <code>i</code> is 1 and for <code>j</code> is -1.
+If it finds any invalid byte sequence,
+returns <b>fail</b> plus the position of the first invalid byte.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-utf8.offset"><code>utf8.offset (s, n [, i])</code></a></h3>
+
+
+<p>
+Returns the position (in bytes) where the encoding of the
+<code>n</code>-th character of <code>s</code>
+(counting from position <code>i</code>) starts.
+A negative <code>n</code> gets characters before position <code>i</code>.
+The default for <code>i</code> is 1 when <code>n</code> is non-negative
+and <code>#s + 1</code> otherwise,
+so that <code>utf8.offset(s, -n)</code> gets the offset of the
+<code>n</code>-th character from the end of the string.
+If the specified character is neither in the subject
+nor right after its end,
+the function returns <b>fail</b>.
+
+
+<p>
+As a special case,
+when <code>n</code> is 0 the function returns the start of the encoding
+of the character that contains the <code>i</code>-th byte of <code>s</code>.
+
+
+<p>
+This function assumes that <code>s</code> is a valid UTF-8 string.
+
+

+
+<h2>6.6 &ndash; <a name="6.6">Table Manipulation</a></h2>
+
+<p>
+This library provides generic functions for table manipulation.
+It provides all its functions inside the table <a name="pdf-table"><code>table</code></a>.
+
+
+<p>
+Remember that, whenever an operation needs the length of a table,
+all caveats about the length operator apply (see <a href="#3.4.7">&sect;3.4.7</a>).
+All functions ignore non-numeric keys
+in the tables given as arguments.
+
+
+<p>
+<hr><h3><a name="pdf-table.concat"><code>table.concat (list [, sep [, i [, j]]])</code></a></h3>
+
+
+<p>
+Given a list where all elements are strings or numbers,
+returns the string <code>list[i]..sep..list[i+1] &middot;&middot;&middot; sep..list[j]</code>.
+The default value for <code>sep</code> is the empty string,
+the default for <code>i</code> is 1,
+and the default for <code>j</code> is <code>#list</code>.
+If <code>i</code> is greater than <code>j</code>, returns the empty string.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-table.insert"><code>table.insert (list, [pos,] value)</code></a></h3>
+
+
+<p>
+Inserts element <code>value</code> at position <code>pos</code> in <code>list</code>,
+shifting up the elements
+<code>list[pos], list[pos+1], &middot;&middot;&middot;, list[#list]</code>.
+The default value for <code>pos</code> is <code>#list+1</code>,
+so that a call <code>table.insert(t,x)</code> inserts <code>x</code> at the end
+of the list <code>t</code>.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-table.move"><code>table.move (a1, f, e, t [,a2])</code></a></h3>
+
+
+<p>
+Moves elements from the table <code>a1</code> to the table <code>a2</code>,
+performing the equivalent to the following
+multiple assignment:
+<code>a2[t],&middot;&middot;&middot; = a1[f],&middot;&middot;&middot;,a1[e]</code>.
+The default for <code>a2</code> is <code>a1</code>.
+The destination range can overlap with the source range.
+The number of elements to be moved must fit in a Lua integer.
+
+
+<p>
+Returns the destination table <code>a2</code>.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-table.pack"><code>table.pack (&middot;&middot;&middot;)</code></a></h3>
+
+
+<p>
+Returns a new table with all arguments stored into keys 1, 2, etc.

+<p>
+<hr><h3><a name="pdf-table.remove"><code>table.remove (list [, pos])</code></a></h3>
+
+
+<p>
+Removes from <code>list</code> the element at position <code>pos</code>,

+When <code>pos</code> is an integer between 1 and <code>#list</code>,
+it shifts down the elements
+<code>list[pos+1], list[pos+2], &middot;&middot;&middot;, list[#list]</code>
+and erases element <code>list[#list]</code>;
+The index <code>pos</code> can also be 0 when <code>#list</code> is 0,
+or <code>#list + 1</code>.
+
+
+<p>
+The default value for <code>pos</code> is <code>#list</code>,
+so that a call <code>table.remove(l)</code> removes the last element

+
+
+
+
+<p>
+<hr><h3><a name="pdf-table.sort"><code>table.sort (list [, comp])</code></a></h3>
+
+
+<p>
+Sorts the list elements in a given order, <em>in-place</em>,
+from <code>list[1]</code> to <code>list[#list]</code>.
+If <code>comp</code> is given,
+then it must be a function that receives two list elements
+and returns true when the first element must come
+before the second in the final order,
+so that, after the sort,
+<code>i &lt;= j</code> implies <code>not comp(list[j],list[i])</code>.
+If <code>comp</code> is not given,
+then the standard Lua operator <code>&lt;</code> is used instead.
+
+
+<p>
+The <code>comp</code> function must define a consistent order;
+more formally, the function must define a strict weak order.
+(A weak order is similar to a total order,
+but it can equate different elements for comparison purposes.)
+
+
+<p>
+The sort algorithm is not stable:
+Different elements considered equal by the given order
+may have their relative positions changed by the sort.

+When called with two integers <code>m</code> and <code>n</code>,
+<code>math.random</code> returns a pseudo-random integer
+with uniform distribution in the range <em>[m, n]</em>.
+The call <code>math.random(n)</code>, for a positive <code>n</code>,
+is equivalent to <code>math.random(1,n)</code>.
+The call <code>math.random(0)</code> produces an integer with

+The default for <code>y</code> is zero.
+
+

+When called with no arguments,
+Lua generates a seed with

+
+
+<p>
+This function returns the two seed components

+<h2>6.8 &ndash; <a name="6.8">Input and Output Facilities</a></h2>
+
+<p>
+The I/O library provides two different styles for file manipulation.
+The first one uses implicit file handles;
+that is, there are operations to set a default input file and a
+default output file,
+and all input/output operations are done over these default files.
+The second style uses explicit file handles.
+
+
+<p>
+When using implicit file handles,
+all operations are supplied by table <a name="pdf-io"><code>io</code></a>.
+When using explicit file handles,
+the operation <a href="#pdf-io.open"><code>io.open</code></a> returns a file handle
+and then all operations are supplied as methods of the file handle.
+
+
+<p>
+The metatable for file handles provides metamethods
+for <code>__gc</code> and <code>__close</code> that try
+to close the file when called.
+
+
+<p>
+The table <code>io</code> also provides
+three predefined file handles with their usual meanings from C:
+<a name="pdf-io.stdin"><code>io.stdin</code></a>, <a name="pdf-io.stdout"><code>io.stdout</code></a>, and <a name="pdf-io.stderr"><code>io.stderr</code></a>.
+The I/O library never closes these files.
+
+
+<p>
+Unless otherwise stated,
+all I/O functions return <b>fail</b> on failure,
+plus an error message as a second result and
+a system-dependent error code as a third result,
+and some non-false value on success.
+On non-POSIX systems,
+the computation of the error message and error code
+in case of errors
+may be not thread safe,
+because they rely on the global C variable <code>errno</code>.
+
+
+<p>
+<hr><h3><a name="pdf-io.close"><code>io.close ([file])</code></a></h3>
+
+
+<p>
+Equivalent to <code>file:close()</code>.
+Without a <code>file</code>, closes the default output file.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-io.flush"><code>io.flush ()</code></a></h3>
+
+
+<p>
+Equivalent to <code>io.output():flush()</code>.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-io.input"><code>io.input ([file])</code></a></h3>
+
+
+<p>
+When called with a file name, it opens the named file (in text mode),
+and sets its handle as the default input file.
+When called with a file handle,
+it simply sets this file handle as the default input file.
+When called without arguments,
+it returns the current default input file.
+
+
+<p>
+In case of errors this function raises the error,
+instead of returning an error code.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-io.lines"><code>io.lines ([filename, &middot;&middot;&middot;])</code></a></h3>
+
+
+<p>
+Opens the given file name in read mode
+and returns an iterator function that
+works like <code>file:lines(&middot;&middot;&middot;)</code> over the opened file.
+When the iterator function fails to read any value,
+it automatically closes the file.
+Besides the iterator function,
+<code>io.lines</code> returns three other values:
+two <b>nil</b> values as placeholders,
+plus the created file handle.
+Therefore, when used in a generic <b>for</b> loop,
+the file is closed also if the loop is interrupted by an
+error or a <b>break</b>.
+
+
+<p>
+The call <code>io.lines()</code> (with no file name) is equivalent
+to <code>io.input():lines("l")</code>;
+that is, it iterates over the lines of the default input file.
+In this case, the iterator does not close the file when the loop ends.
+
+
+<p>
+In case of errors opening the file,
+this function raises the error,
+instead of returning an error code.
+

+
+
+<p>
+This function opens a file,
+in the mode specified in the string <code>mode</code>.
+In case of success,
+it returns a new file handle.
+
+
+<p>
+The <code>mode</code> string can be any of the following:
+
+<ul>
+<li><b>"<code>r</code>": </b> read mode (the default);</li>
+<li><b>"<code>w</code>": </b> write mode;</li>
+<li><b>"<code>a</code>": </b> append mode;</li>

+<li><b>"<code>w+</code>": </b> update mode, all previous data is erased;</li>
+<li><b>"<code>a+</code>": </b> append update mode, previous data is preserved,
+  writing is only allowed at the end of file.</li>
+</ul><p>
+The <code>mode</code> string can also have a '<code>b</code>' at the end,
+which is needed in some systems to open the file in binary mode.

+
+
+<p>
+When closing a file handle created with <a href="#pdf-io.popen"><code>io.popen</code></a>,

+uses "<code>l</code>" as a default.
+As an example, the construction
+
+<pre>
+     for c in file:lines(1) do <em>body</em> end
+</pre><p>
+will iterate over all characters of the file,
+starting at the current position.

+
+
+
+
+<p>
+<hr><h3><a name="pdf-file:read"><code>file:read (&middot;&middot;&middot;)</code></a></h3>
+
+
+<p>
+Reads the file <code>file</code>,
+according to the given formats, which specify what to read.
+For each format,
+the function returns a string or a number with the characters read,
+or <b>fail</b> if it cannot read data with the specified format.
+(In this latter case,
+the function does not read subsequent formats.)
+When called without arguments,
+it uses a default format that reads the next line
+(see below).
+
+
+<p>
+The available formats are
+
+<ul>
+
+<li><b>"<code>n</code>": </b>
+reads a numeral and returns it as a float or an integer,
+following the lexical conventions of Lua.
+(The numeral may have leading whitespaces and a sign.)
+This format always reads the longest input sequence that
+is a valid prefix for a numeral;
+if that prefix does not form a valid numeral
+(e.g., an empty string, "<code>0x</code>", or "<code>3.4e-</code>")
+or it is too long (more than 200 characters),
+it is discarded and the format returns <b>fail</b>.
+</li>
+
+<li><b>"<code>a</code>": </b>
+reads the whole file, starting at the current position.
+On end of file, it returns the empty string;
+this format never fails.
+</li>
+
+<li><b>"<code>l</code>": </b>
+reads the next line skipping the end of line,
+returning <b>fail</b> on end of file.
+This is the default format.
+</li>
+
+<li><b>"<code>L</code>": </b>
+reads the next line keeping the end-of-line character (if present),
+returning <b>fail</b> on end of file.
+</li>
+
+<li><b><em>number</em>: </b>
+reads a string with up to this number of bytes,
+returning <b>fail</b> on end of file.
+If <code>number</code> is zero,
+it reads nothing and returns an empty string,
+or <b>fail</b> on end of file.
+</li>
+
+</ul><p>
+The formats "<code>l</code>" and "<code>L</code>" should be used only for text files.
+

+
+
+<p>
+Sets and gets the file position,

+specified by the string <code>whence</code>, as follows:
+
+<ul>
+<li><b>"<code>set</code>": </b> base is position 0 (beginning of the file);</li>
+<li><b>"<code>cur</code>": </b> base is current position;</li>
+<li><b>"<code>end</code>": </b> base is end of file;</li>
+</ul><p>
+In case of success, <code>seek</code> returns the final file position,
+measured in bytes from the beginning of the file.
+If <code>seek</code> fails, it returns <b>fail</b>,
+plus a string describing the error.
+
+
+<p>
+The default value for <code>whence</code> is <code>"cur"</code>,
+and for <code>offset</code> is 0.
+Therefore, the call <code>file:seek()</code> returns the current
+file position, without changing it;
+the call <code>file:seek("set")</code> sets the position to the
+beginning of the file (and returns 0);
+and the call <code>file:seek("end")</code> sets the position to the
+end of the file, and returns its size.

+<li><b>"<code>full</code>": </b> full buffering.</li>
+<li><b>"<code>line</code>": </b> line buffering.</li>

+<p>
+For the last two cases,
+<code>size</code> is a hint for the size of the buffer, in bytes.

+the function closes the Lua state before exiting (see <a href="#lua_close"><code>lua_close</code></a>).
+
+
+
+
+<p>
+<hr><h3><a name="pdf-os.getenv"><code>os.getenv (varname)</code></a></h3>
+
+
+<p>
+Returns the value of the process environment variable <code>varname</code>
+or <b>fail</b> if the variable is not defined.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-os.remove"><code>os.remove (filename)</code></a></h3>
+
+
+<p>
+Deletes the file (or empty directory, on POSIX systems)
+with the given name.
+If this function fails, it returns <b>fail</b>
+plus a string describing the error and the error code.
+Otherwise, it returns true.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-os.rename"><code>os.rename (oldname, newname)</code></a></h3>
+
+
+<p>
+Renames the file or directory named <code>oldname</code> to <code>newname</code>.
+If this function fails, it returns <b>fail</b>,
+plus a string describing the error and the error code.
+Otherwise, it returns true.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-os.setlocale"><code>os.setlocale (locale [, category])</code></a></h3>
+
+
+<p>
+Sets the current locale of the program.
+<code>locale</code> is a system-dependent string specifying a locale;
+<code>category</code> is an optional string describing which category to change:
+<code>"all"</code>, <code>"collate"</code>, <code>"ctype"</code>,
+<code>"monetary"</code>, <code>"numeric"</code>, or <code>"time"</code>;
+the default category is <code>"all"</code>.
+The function returns the name of the new locale,
+or <b>fail</b> if the request cannot be honored.
+
+
+<p>
+If <code>locale</code> is the empty string,
+the current locale is set to an implementation-defined native locale.
+If <code>locale</code> is the string "<code>C</code>",
+the current locale is set to the standard C locale.
+
+
+<p>
+When called with <b>nil</b> as the first argument,
+this function only returns the name of the current locale
+for the given category.
+
+
+<p>
+This function may be not thread safe
+because of its reliance on C&nbsp;function <code>setlocale</code>.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-os.time"><code>os.time ([table])</code></a></h3>
+
+
+<p>
+Returns the current time when called without arguments,
+or a time representing the local date and time specified by the given table.
+This table must have fields <code>year</code>, <code>month</code>, and <code>day</code>,
+and may have fields
+<code>hour</code> (default is 12),
+<code>min</code> (default is 0),
+<code>sec</code> (default is 0),
+and <code>isdst</code> (default is <b>nil</b>).
+Other fields are ignored.
+For a description of these fields, see the <a href="#pdf-os.date"><code>os.date</code></a> function.
+
+
+<p>
+When the function is called,
+the values in these fields do not need to be inside their valid ranges.
+For instance, if <code>sec</code> is -10,
+it means 10 seconds before the time specified by the other fields;
+if <code>hour</code> is 1000,
+it means 1000 hours after the time specified by the other fields.
+
+
+<p>
+The returned value is a number, whose meaning depends on your system.
+In POSIX, Windows, and some other systems,
+this number counts the number
+of seconds since some given start time (the "epoch").
+In other systems, the meaning is not specified,
+and the number returned by <code>time</code> can be used only as an argument to
+<a href="#pdf-os.date"><code>os.date</code></a> and <a href="#pdf-os.difftime"><code>os.difftime</code></a>.
+
+
+<p>
+When called with a table,
+<code>os.time</code> also normalizes all the fields
+documented in the <a href="#pdf-os.date"><code>os.date</code></a> function,
+so that they represent the same time as before the call
+but with values inside their valid ranges.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-os.tmpname"><code>os.tmpname ()</code></a></h3>
+
+
+<p>
+Returns a string with a file name that can
+be used for a temporary file.
+The file must be explicitly opened before its use
+and explicitly removed when no longer needed.
+
+
+<p>
+In POSIX systems,
+this function also creates a file with that name,
+to avoid security risks.
+(Someone else might create the file with wrong permissions
+in the time between getting the name and creating the file.)
+You still have to open the file to use it
+and to remove it (even if you do not use it).
+
+
+<p>
+When possible,
+you may prefer to use <a href="#pdf-io.tmpfile"><code>io.tmpfile</code></a>,
+which automatically removes the file when the program ends.

+<h2>6.10 &ndash; <a name="6.10">The Debug Library</a></h2>
+
+<p>
+This library provides
+the functionality of the debug interface (<a href="#4.7">&sect;4.7</a>) to Lua programs.
+You should exert care when using this library.
+Several of its functions
+violate basic assumptions about Lua code
+(e.g., that variables local to a function
+cannot be accessed from outside;
+that userdata metatables cannot be changed by Lua code;
+that Lua programs do not crash)
+and therefore can compromise otherwise secure code.
+Moreover, some functions in this library may be slow.
+
+
+<p>
+All functions in this library are provided
+inside the <a name="pdf-debug"><code>debug</code></a> table.
+All functions that operate over a thread
+have an optional first argument which is the
+thread to operate over.
+The default is always the current thread.
+
+
+<p>
+<hr><h3><a name="pdf-debug.debug"><code>debug.debug ()</code></a></h3>
+
+
+<p>
+Enters an interactive mode with the user,
+running each string that the user enters.
+Using simple commands and other debug facilities,
+the user can inspect global and local variables,
+change their values, evaluate expressions, and so on.
+A line containing only the word <code>cont</code> finishes this function,
+so that the caller continues its execution.
+
+
+<p>
+Note that commands for <code>debug.debug</code> are not lexically nested
+within any function and so have no direct access to local variables.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.gethook"><code>debug.gethook ([thread])</code></a></h3>
+
+
+<p>
+Returns the current hook settings of the thread, as three values:
+the current hook function, the current hook mask,
+and the current hook count,
+as set by the <a href="#pdf-debug.sethook"><code>debug.sethook</code></a> function.
+
+
+<p>
+Returns <b>fail</b> if there is no active hook.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.getinfo"><code>debug.getinfo ([thread,] f [, what])</code></a></h3>
+
+
+<p>
+Returns a table with information about a function.
+You can give the function directly
+or you can give a number as the value of <code>f</code>,
+which means the function running at level <code>f</code> of the call stack
+of the given thread:
+level&nbsp;0 is the current function (<code>getinfo</code> itself);
+level&nbsp;1 is the function that called <code>getinfo</code>
+(except for tail calls, which do not count in the stack);
+and so on.
+If <code>f</code> is a number greater than the number of active functions,
+then <code>getinfo</code> returns <b>fail</b>.
+
+
+<p>
+The returned table can contain all the fields returned by <a href="#lua_getinfo"><code>lua_getinfo</code></a>,
+with the string <code>what</code> describing which fields to fill in.
+The default for <code>what</code> is to get all information available,
+except the table of valid lines.
+If present,
+the option '<code>f</code>'
+adds a field named <code>func</code> with the function itself.
+If present,
+the option '<code>L</code>'
+adds a field named <code>activelines</code> with the table of
+valid lines.
+
+
+<p>
+For instance, the expression <code>debug.getinfo(1,"n").name</code> returns
+a name for the current function,
+if a reasonable name can be found,
+and the expression <code>debug.getinfo(print)</code>
+returns a table with all available information
+about the <a href="#pdf-print"><code>print</code></a> function.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.getlocal"><code>debug.getlocal ([thread,] f, local)</code></a></h3>
+
+
+<p>
+This function returns the name and the value of the local variable
+with index <code>local</code> of the function at level <code>f</code> of the stack.
+This function accesses not only explicit local variables,
+but also parameters and temporary values.
+
+
+<p>
+The first parameter or local variable has index&nbsp;1, and so on,
+following the order that they are declared in the code,
+counting only the variables that are active
+in the current scope of the function.
+Compile-time constants may not appear in this listing,
+if they were optimized away by the compiler.
+Negative indices refer to vararg arguments;
+-1 is the first vararg argument.
+The function returns <b>fail</b>
+if there is no variable with the given index,
+and raises an error when called with a level out of range.
+(You can call <a href="#pdf-debug.getinfo"><code>debug.getinfo</code></a> to check whether the level is valid.)
+
+
+<p>
+Variable names starting with '<code>(</code>' (open parenthesis) 
+represent variables with no known names
+(internal variables such as loop control variables,
+and variables from chunks saved without debug information).
+
+
+<p>
+The parameter <code>f</code> may also be a function.
+In that case, <code>getlocal</code> returns only the name of function parameters.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.getmetatable"><code>debug.getmetatable (value)</code></a></h3>
+
+
+<p>
+Returns the metatable of the given <code>value</code>
+or <b>nil</b> if it does not have a metatable.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.getregistry"><code>debug.getregistry ()</code></a></h3>
+
+
+<p>
+Returns the registry table (see <a href="#4.3">&sect;4.3</a>).
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.getupvalue"><code>debug.getupvalue (f, up)</code></a></h3>
+
+
+<p>
+This function returns the name and the value of the upvalue
+with index <code>up</code> of the function <code>f</code>.
+The function returns <b>fail</b>
+if there is no upvalue with the given index.
+
+
+<p>
+(For Lua functions,
+upvalues are the external local variables that the function uses,
+and that are consequently included in its closure.)
+
+
+<p>
+For C&nbsp;functions, this function uses the empty string <code>""</code>
+as a name for all upvalues.
+
+
+<p>
+Variable name '<code>?</code>' (interrogation mark)
+represents variables with no known names
+(variables from chunks saved without debug information).
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.getuservalue"><code>debug.getuservalue (u, n)</code></a></h3>
+
+
+<p>
+Returns the <code>n</code>-th user value associated
+to the userdata <code>u</code> plus a boolean,
+<b>false</b> if the userdata does not have that value.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.sethook"><code>debug.sethook ([thread,] hook, mask [, count])</code></a></h3>
+
+
+<p>
+Sets the given function as the debug hook.
+The string <code>mask</code> and the number <code>count</code> describe
+when the hook will be called.
+The string mask may have any combination of the following characters,
+with the given meaning:
+
+<ul>
+<li><b>'<code>c</code>': </b> the hook is called every time Lua calls a function;</li>
+<li><b>'<code>r</code>': </b> the hook is called every time Lua returns from a function;</li>
+<li><b>'<code>l</code>': </b> the hook is called every time Lua enters a new line of code.</li>
+</ul><p>
+Moreover,
+with a <code>count</code> different from zero,
+the hook is called also after every <code>count</code> instructions.
+
+
+<p>
+When called without arguments,
+<a href="#pdf-debug.sethook"><code>debug.sethook</code></a> turns off the hook.
+
+
+<p>
+When the hook is called, its first parameter is a string
+describing the event that has triggered its call:
+<code>"call"</code>, <code>"tail call"</code>, <code>"return"</code>,
+<code>"line"</code>, and <code>"count"</code>.
+For line events,
+the hook also gets the new line number as its second parameter.
+Inside a hook,
+you can call <code>getinfo</code> with level&nbsp;2 to get more information about
+the running function.
+(Level&nbsp;0 is the <code>getinfo</code> function,
+and level&nbsp;1 is the hook function.)

+The function returns <b>fail</b> if there is no local
+variable with the given index,
+and raises an error when called with a <code>level</code> out of range.
+(You can call <code>getinfo</code> to check whether the level is valid.)

+<hr><h3><a name="pdf-debug.traceback"><code>debug.traceback ([thread,] [message [, level]])</code></a></h3>
+
+
+<p>
+If <code>message</code> is present but is neither a string nor <b>nil</b>,
+this function returns <code>message</code> without further processing.
+Otherwise,
+it returns a string with a traceback of the call stack.
+The optional <code>message</code> string is appended
+at the beginning of the traceback.
+An optional <code>level</code> number tells at which level

+(default is 1, the function calling <code>traceback</code>).
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.upvalueid"><code>debug.upvalueid (f, n)</code></a></h3>
+
+
+<p>
+Returns a unique identifier (as a light userdata)
+for the upvalue numbered <code>n</code>
+from the given function.
+
+
+<p>
+These unique identifiers allow a program to check whether different
+closures share upvalues.
+Lua closures that share an upvalue
+(that is, that access a same external local variable)
+will return identical ids for those upvalue indices.

+
+
+<h1>7 &ndash; <a name="7">Lua Standalone</a></h1>
+
+<p>
+Although Lua has been designed as an extension language,
+to be embedded in a host C&nbsp;program,
+it is also frequently used as a standalone language.
+An interpreter for Lua as a standalone language,
+called simply <code>lua</code>,
+is provided with the standard distribution.
+The standalone interpreter includes
+all standard libraries.
+Its usage is:
+
+<pre>
+     lua [options] [script [args]]
+</pre><p>
+The options are:
+
+<ul>
+<li><b><code>-e <em>stat</em></code>: </b> execute string <em>stat</em>;</li>
+<li><b><code>-i</code>: </b> enter interactive mode after running <em>script</em>;</li>
+<li><b><code>-l <em>mod</em></code>: </b> "require" <em>mod</em> and assign the
+  result to global <em>mod</em>;</li>
+<li><b><code>-l <em>g=mod</em></code>: </b> "require" <em>mod</em> and assign the
+  result to global <em>g</em>;</li>
+<li><b><code>-v</code>: </b> print version information;</li>
+<li><b><code>-E</code>: </b> ignore environment variables;</li>
+<li><b><code>-W</code>: </b> turn warnings on;</li>
+<li><b><code>--</code>: </b> stop handling options;</li>
+<li><b><code>-</code>: </b> execute <code>stdin</code> as a file and stop handling options.</li>
+</ul><p>
+(The form <code>-l <em>g=mod</em></code> was introduced in release&nbsp;5.4.4.)
+
+
+<p>
+After handling its options, <code>lua</code> runs the given <em>script</em>.
+When called without arguments,
+<code>lua</code> behaves as <code>lua -v -i</code>
+when the standard input (<code>stdin</code>) is a terminal,
+and as <code>lua -</code> otherwise.
+
+
+<p>
+When called without the option <code>-E</code>,
+the interpreter checks for an environment variable <a name="pdf-LUA_INIT_5_4"><code>LUA_INIT_5_4</code></a>
+(or <a name="pdf-LUA_INIT"><code>LUA_INIT</code></a> if the versioned name is not defined)
+before running any argument.
+If the variable content has the format <code>@<em>filename</em></code>,
+then <code>lua</code> executes the file.
+Otherwise, <code>lua</code> executes the string itself.
+
+
+<p>
+When called with the option <code>-E</code>,
+Lua does not consult any environment variables.
+In particular,
+the values of <a href="#pdf-package.path"><code>package.path</code></a> and <a href="#pdf-package.cpath"><code>package.cpath</code></a>
+are set with the default paths defined in <code>luaconf.h</code>.
+
+
+<p>
+The options <code>-e</code>, <code>-l</code>, and <code>-W</code> are handled in
+the order they appear.
+For instance, an invocation like
+
+<pre>
+     $ lua -e 'a=1' -llib1 script.lua
+</pre><p>
+will first set <code>a</code> to 1, then require the library <code>lib1</code>,
+and finally run the file <code>script.lua</code> with no arguments.
+(Here <code>$</code> is the shell prompt. Your prompt may be different.)
+
+
+<p>
+Before running any code,
+<code>lua</code> collects all command-line arguments
+in a global table called <code>arg</code>.
+The script name goes to index 0,
+the first argument after the script name goes to index 1,
+and so on.
+Any arguments before the script name
+(that is, the interpreter name plus its options)
+go to negative indices.
+For instance, in the call
+
+<pre>
+     $ lua -la b.lua t1 t2
+</pre><p>
+the table is like this:
+
+<pre>
+     arg = { [-2] = "lua", [-1] = "-la",
+             [0] = "b.lua",
+             [1] = "t1", [2] = "t2" }
+</pre><p>
+If there is no script in the call,
+the interpreter name goes to index 0,
+followed by the other arguments.
+For instance, the call
+
+<pre>
+     $ lua -e "print(arg[1])"
+</pre><p>
+will print "<code>-e</code>".
+If there is a script,
+the script is called with arguments
+<code>arg[1]</code>, &middot;&middot;&middot;, <code>arg[#arg]</code>.
+Like all chunks in Lua,
+the script is compiled as a variadic function.
+
+
+<p>
+In interactive mode,
+Lua repeatedly prompts and waits for a line.
+After reading a line,
+Lua first try to interpret the line as an expression.
+If it succeeds, it prints its value.
+Otherwise, it interprets the line as a statement.
+If you write an incomplete statement,
+the interpreter waits for its completion
+by issuing a different prompt.
+
+
+<p>
+If the global variable <a name="pdf-_PROMPT"><code>_PROMPT</code></a> contains a string,
+then its value is used as the prompt.
+Similarly, if the global variable <a name="pdf-_PROMPT2"><code>_PROMPT2</code></a> contains a string,
+its value is used as the secondary prompt
+(issued during incomplete statements).
+
+
+<p>
+In case of unprotected errors in the script,
+the interpreter reports the error to the standard error stream.
+If the error object is not a string but
+has a metamethod <code>__tostring</code>,
+the interpreter calls this metamethod to produce the final message.
+Otherwise, the interpreter converts the error object to a string
+and adds a stack traceback to it.
+When warnings are on,
+they are simply printed in the standard error output.
+
+
+<p>
+When finishing normally,
+the interpreter closes its main Lua state
+(see <a href="#lua_close"><code>lua_close</code></a>).
+The script can avoid this step by
+calling <a href="#pdf-os.exit"><code>os.exit</code></a> to terminate.
+
+
+<p>
+To allow the use of Lua as a
+script interpreter in Unix systems,
+Lua skips the first line of a file chunk if it starts with <code>#</code>.
+Therefore, Lua scripts can be made into executable programs
+by using <code>chmod +x</code> and the&nbsp;<code>#!</code> form,
+as in
+
+<pre>
+     #!/usr/local/bin/lua
+</pre><p>
+Of course,
+the location of the Lua interpreter may be different in your machine.
+If <code>lua</code> is in your <code>PATH</code>,
+then
+
+<pre>
+     #!/usr/bin/env lua
+</pre><p>
+is a more portable solution.
+

+
+<h1>8 &ndash; <a name="8">Incompatibilities with the Previous Version</a></h1>
+
+
+
+<p>
+Here we list the incompatibilities that you may find when moving a program
+from Lua&nbsp;5.3 to Lua&nbsp;5.4.
+
+
+<p>
+You can avoid some incompatibilities by compiling Lua with
+appropriate options (see file <code>luaconf.h</code>).
+However,
+all these compatibility options will be removed in the future.
+More often than not,
+compatibility issues arise when these compatibility options
+are removed.
+So, whenever you have the chance,
+you should try to test your code with a version of Lua compiled
+with all compatibility options turned off.
+That will ease transitions to newer versions of Lua.
+
+
+<p>
+Lua versions can always change the C API in ways that
+do not imply source-code changes in a program,
+such as the numeric values for constants
+or the implementation of functions as macros.
+Therefore,
+you should never assume that binaries are compatible between
+different Lua versions.
+Always recompile clients of the Lua API when
+using a new version.
+
+
+<p>
+Similarly, Lua versions can always change the internal representation
+of precompiled chunks;
+precompiled chunks are not compatible between different Lua versions.
+
+
+<p>
+The standard paths in the official distribution may
+change between versions.
+
+
+
+
+
+<h2>8.1 &ndash; <a name="8.1">Incompatibilities in the Language</a></h2>
+<ul>
+
+<li>
+The coercion of strings to numbers in
+arithmetic and bitwise operations
+has been removed from the core language.
+The string library does a similar job
+for arithmetic (but not for bitwise) operations
+using the string metamethods.
+However, unlike in previous versions,
+the new implementation preserves the implicit type of the numeral
+in the string.
+For instance, the result of <code>"1" + "2"</code> now is an integer,
+not a float.
+</li>
+
+<li>
+Literal decimal integer constants that overflow are read as floats,
+instead of wrapping around.
+You can use hexadecimal notation for such constants if you
+want the old behavior
+(reading them as integers with wrap around).
+</li>
+
+<li>
+The use of the <code>__lt</code> metamethod to emulate <code>__le</code>
+has been removed.
+When needed, this metamethod must be explicitly defined.
+</li>
+
+<li>
+The semantics of the numerical <b>for</b> loop
+over integers changed in some details.
+In particular, the control variable never wraps around.
+</li>
+
+<li>
+A label for a <b>goto</b> cannot be declared where a label with the same
+name is visible, even if this other label is declared in an enclosing
+block.
+</li>
+
+<li>
+When finalizing an object,
+Lua does not ignore <code>__gc</code> metamethods that are not functions.
+Any value will be called, if present.
+(Non-callable values will generate a warning,
+like any other error when calling a finalizer.)
+</li>
+
+</ul>
+
+

+<h2>8.2 &ndash; <a name="8.2">Incompatibilities in the Libraries</a></h2>
+<ul>
+
+<li>
+The function <a href="#pdf-print"><code>print</code></a> does not call <a href="#pdf-tostring"><code>tostring</code></a>
+to format its arguments;
+instead, it has this functionality hardwired.
+You should use <code>__tostring</code> to modify how values are printed.
+</li>
+
+<li>
+The pseudo-random number generator used by the function <a href="#pdf-math.random"><code>math.random</code></a>
+now starts with a somewhat random seed.
+Moreover, it uses a different algorithm.
+</li>
+
+<li>
+By default, the decoding functions in the <a href="#pdf-utf8"><code>utf8</code></a> library
+do not accept surrogates as valid code points.
+An extra parameter in these functions makes them more permissive.
+</li>
+
+<li>
+The options "<code>setpause</code>" and "<code>setstepmul</code>"
+of the function <a href="#pdf-collectgarbage"><code>collectgarbage</code></a> are deprecated.
+You should use the new option "<code>incremental</code>" to set them.
+</li>
+
+<li>
+The function <a href="#pdf-io.lines"><code>io.lines</code></a> now returns four values,
+instead of just one.
+That can be a problem when it is used as the sole
+argument to another function that has optional parameters,
+such as in <code>load(io.lines(filename, "L"))</code>.
+To fix that issue,
+you can wrap the call into parentheses,
+to adjust its number of results to one.
+</li>
+
+</ul>
+
+
+
+
+<h2>8.3 &ndash; <a name="8.3">Incompatibilities in the API</a></h2>
+
+
+<ul>
+
+<li>
+Full userdata now has an arbitrary number of associated user values.
+Therefore, the functions <code>lua_newuserdata</code>,
+<code>lua_setuservalue</code>, and <code>lua_getuservalue</code> were
+replaced by <a href="#lua_newuserdatauv"><code>lua_newuserdatauv</code></a>,
+<a href="#lua_setiuservalue"><code>lua_setiuservalue</code></a>, and <a href="#lua_getiuservalue"><code>lua_getiuservalue</code></a>,
+which have an extra argument.
+
+
+<p>
+For compatibility, the old names still work as macros assuming
+one single user value.
+Note, however, that userdata with zero user values
+are more efficient memory-wise.
+</li>
+
+<li>
+The function <a href="#lua_resume"><code>lua_resume</code></a> has an extra parameter.
+This out parameter returns the number of values on
+the top of the stack that were yielded or returned by the coroutine.
+(In previous versions,
+those values were the entire stack.)
+</li>
+
+<li>
+The function <a href="#lua_version"><code>lua_version</code></a> returns the version number,
+instead of an address of the version number.
+The Lua core should work correctly with libraries using their
+own static copies of the same core,
+so there is no need to check whether they are using the same
+address space.
+</li>
+
+<li>
+The constant <code>LUA_ERRGCMM</code> was removed.
+Errors in finalizers are never propagated;
+instead, they generate a warning.
+</li>
+
+<li>
+The options <code>LUA_GCSETPAUSE</code> and <code>LUA_GCSETSTEPMUL</code>
+of the function <a href="#lua_gc"><code>lua_gc</code></a> are deprecated.
+You should use the new option <code>LUA_GCINC</code> to set them.
+</li>
+
+</ul>

+
+<H2><A NAME="about">About Lua</A></H2>
+<P>
+Lua is a powerful, efficient, lightweight, embeddable scripting language
+developed by a
+<A HREF="http://www.lua.org/authors.html">team</A>
+at
+<A HREF="http://www.puc-rio.br/">PUC-Rio</A>,
+the Pontifical Catholic University of Rio de Janeiro in Brazil.
+Lua is
+<A HREF="#license">free software</A>
+used in
+<A HREF="http://www.lua.org/uses.html">many products and projects</A>
+around the world.
+
+<P>
+Lua's
+<A HREF="http://www.lua.org/">official web site</A>
+provides complete information
+about Lua,
+including
+an
+<A HREF="http://www.lua.org/about.html">executive summary</A>
+and
+updated
+<A HREF="http://www.lua.org/docs.html">documentation</A>,
+especially the
+<A HREF="http://www.lua.org/manual/5.4/">reference manual</A>,
+which may differ slightly from the
+<A HREF="contents.html">local copy</A>
+distributed in this package.
+
+<H2><A NAME="install">Installing Lua</A></H2>
+<P>
+Lua is distributed in
+<A HREF="http://www.lua.org/ftp/">source</A>
+form.
+You need to build it before using it.
+Building Lua should be straightforward
+because
+Lua is implemented in pure ANSI C and compiles unmodified in all known
+platforms that have an ANSI C compiler.
+Lua also compiles unmodified as C++.
+The instructions given below for building Lua are for Unix-like platforms,
+such as Linux and Mac OS X.
+See also
+<A HREF="#other">instructions for other systems</A>
+and
+<A HREF="#customization">customization options</A>.
+
+<P>
+If you don't have the time or the inclination to compile Lua yourself,
+get a binary from
+<A HREF="http://lua-users.org/wiki/LuaBinaries">LuaBinaries</A>.
+
+<H3>Building Lua</H3>
+<P>
+In most common Unix-like platforms, simply do "<KBD>make</KBD>".
+Here are the details.
+
+<OL>
+<LI>
+Open a terminal window and move to
+the top-level directory, which is named <TT>lua-5.4.6</TT>.
+The <TT>Makefile</TT> there controls both the build process and the installation process.
+<P>
+<LI>
+  Do "<KBD>make</KBD>". The <TT>Makefile</TT> will guess your platform and build Lua for it.
+<P>
+<LI>
+  If the guess failed, do "<KBD>make help</KBD>" and see if your platform is listed.
+  The platforms currently supported are:
+<P>
+<P CLASS="display">
+   guess aix bsd c89 freebsd generic ios linux linux-readline macosx mingw posix solaris
+</P>
+<P>
+  If your platform is listed, just do "<KBD>make xxx</KBD>", where xxx
+  is your platform name.
+<P>
+  If your platform is not listed, try the closest one or posix, generic,
+  c89, in this order.
+<P>
+<LI>
+The compilation takes only a few moments
+and produces three files in the <TT>src</TT> directory:
+lua (the interpreter),
+luac (the compiler),
+and liblua.a (the library).
+<P>
+<LI>
+  To check that Lua has been built correctly, do "<KBD>make test</KBD>"
+  after building Lua. This will run the interpreter and print its version.
+</OL>
+<P>
+If you're running Linux, try "<KBD>make linux-readline</KBD>" to build the interactive Lua interpreter with handy line-editing and history capabilities.
+If you get compilation errors,
+make sure you have installed the <TT>readline</TT> development package
+(which is probably named <TT>libreadline-dev</TT> or <TT>readline-devel</TT>).
+If you get link errors after that,
+then try "<KBD>make linux-readline MYLIBS=-ltermcap</KBD>".
+
+<H3>Installing Lua</H3>
+<P>
+  Once you have built Lua, you may want to install it in an official
+  place in your system. In this case, do "<KBD>make install</KBD>". The official
+  place and the way to install files are defined in the <TT>Makefile</TT>. You'll
+  probably need the right permissions to install files, and so may need to do "<KBD>sudo make install</KBD>".
+
+<P>
+  To build and install Lua in one step, do "<KBD>make all install</KBD>",
+  or "<KBD>make xxx install</KBD>",
+  where xxx is your platform name.
+
+<P>
+  To install Lua locally after building it, do "<KBD>make local</KBD>".
+  This will create a directory <TT>install</TT> with subdirectories
+  <TT>bin</TT>, <TT>include</TT>, <TT>lib</TT>, <TT>man</TT>, <TT>share</TT>,
+  and install Lua as listed below.
+
+  To install Lua locally, but in some other directory, do
+  "<KBD>make install INSTALL_TOP=xxx</KBD>", where xxx is your chosen directory.
+  The installation starts in the <TT>src</TT> and <TT>doc</TT> directories,
+  so take care if <TT>INSTALL_TOP</TT> is not an absolute path.
+
+<DL CLASS="display">
+<DT>
+    bin:
+<DD>
+    lua luac
+<DT>
+    include:
+<DD>
+    lua.h luaconf.h lualib.h lauxlib.h lua.hpp
+<DT>
+    lib:
+<DD>
+    liblua.a
+<DT>
+    man/man1:
+<DD>
+    lua.1 luac.1
+</DL>
+
+<P>
+  These are the only directories you need for development.
+  If you only want to run Lua programs,
+  you only need the files in <TT>bin</TT> and <TT>man</TT>.
+  The files in <TT>include</TT> and <TT>lib</TT> are needed for
+  embedding Lua in C or C++ programs.
+
+<H3><A NAME="customization">Customization</A></H3>
+<P>
+  Three kinds of things can be customized by editing a file:
+<UL>
+    <LI> Where and how to install Lua &mdash; edit <TT>Makefile</TT>.
+    <LI> How to build Lua &mdash; edit <TT>src/Makefile</TT>.
+    <LI> Lua features &mdash; edit <TT>src/luaconf.h</TT>.
+</UL>
+
+<P>
+  You don't actually need to edit the Makefiles because you may set the
+  relevant variables in the command line when invoking make.
+  Nevertheless, it's probably best to edit and save the Makefiles to
+  record the changes you've made.
+
+<P>
+  On the other hand, if you need to customize some Lua features, you'll need
+  to edit <TT>src/luaconf.h</TT> before building and installing Lua.
+  The edited file will be the one installed, and
+  it will be used by any Lua clients that you build, to ensure consistency.
+  Further customization is available to experts by editing the Lua sources.
+
+<H3><A NAME="other">Building Lua on other systems</A></H3>
+<P>
+  If you're not using the usual Unix tools, then the instructions for
+  building Lua depend on the compiler you use. You'll need to create
+  projects (or whatever your compiler uses) for building the library,
+  the interpreter, and the compiler, as follows:
+
+<DL CLASS="display">
+<DT>
+library:
+<DD>
+lapi.c lcode.c lctype.c ldebug.c ldo.c ldump.c lfunc.c lgc.c llex.c lmem.c lobject.c lopcodes.c lparser.c lstate.c lstring.c ltable.c ltm.c lundump.c lvm.c lzio.c
+lauxlib.c lbaselib.c lcorolib.c ldblib.c liolib.c lmathlib.c loadlib.c loslib.c lstrlib.c ltablib.c lutf8lib.c linit.c
+<DT>
+interpreter:
+<DD>
+  library, lua.c
+<DT>
+compiler:
+<DD>
+  library, luac.c
+</DL>
+
+<P>
+  To use Lua as a library in your own programs, you'll need to know how to
+  create and use libraries with your compiler. Moreover, to dynamically load
+  C libraries for Lua, you'll need to know how to create dynamic libraries
+  and you'll need to make sure that the Lua API functions are accessible to
+  those dynamic libraries &mdash; but <EM>don't</EM> link the Lua library
+  into each dynamic library. For Unix, we recommend that the Lua library
+  be linked statically into the host program and its symbols exported for
+  dynamic linking; <TT>src/Makefile</TT> does this for the Lua interpreter.
+  For Windows, we recommend that the Lua library be a DLL.
+  In all cases, the compiler luac should be linked statically.
+
+<P>
+  As mentioned above, you may edit <TT>src/luaconf.h</TT> to customize
+  some features before building Lua.
+
+<H2><A NAME="changes">Changes since Lua 5.3</A></H2>
+<P>
+Here are the main changes introduced in Lua 5.4.
+The
+<A HREF="contents.html">reference manual</A>
+lists the
+<A HREF="manual.html#8">incompatibilities</A> that had to be introduced.
+
+<H3>Main changes</H3>
+<UL>
+<LI> new generational mode for garbage collection
+<LI> to-be-closed variables
+<LI> const variables
+<LI> userdata can have multiple user values

-@ref basic_json::number_unsigned_t is used for unsigned integers,
-@ref basic_json::number_integer_t is used for signed integers, and
-@ref basic_json::number_float_t is used for floating-point numbers or to
-approximate integers which do not fit in the limits of their respective type.

-@brief comparison operator for JSON types

-Returns an ordering that is similar to Python:
-- order: null < boolean < number < object < array < string < binary
-- furthermore, each type is not smaller than itself
-- discarded values are not comparable
-- binary is represented as a b"" string in python and directly comparable to a
-  string; however, making a binary array directly comparable with a string would
-  be surprising behavior in a JSON file.

+distinguish the stored values, and the functions @ref basic_json::is_null(),
+@ref basic_json::is_object(), @ref basic_json::is_array(),
+@ref basic_json::is_string(), @ref basic_json::is_boolean(),
+@ref basic_json::is_number() (with @ref basic_json::is_number_integer(),
+@ref basic_json::is_number_unsigned(), and @ref basic_json::is_number_float()),
+@ref basic_json::is_discarded(), @ref basic_json::is_primitive(), and
+@ref basic_json::is_structured() rely on it.
+
+@note There are three enumeration entries (number_integer, number_unsigned, and
+number_float), because the library distinguishes these three types for numbers:
+@ref basic_json::number_unsigned_t is used for unsigned integers,
+@ref basic_json::number_integer_t is used for signed integers, and
+@ref basic_json::number_float_t is used for floating-point numbers or to
+approximate integers which do not fit in the limits of their respective type.
