Yamlarh

Yamlarh is now just a name, with this tool you can inject complex data or other formatted files in a formatted file (as json, xml or yaml).

You can inject into your formatted file:

• object
• constant from scope
• Variable from global scope
• Variable from formatted file

You can also import other formatted file inside a formatted file file for overriding

Installation

Through Composer, obviously:

{
    "require": {
        "arhframe/yamlarh": "1.*"
    }
}

Usage

use Arhframe\Yamlarh\Yamlarh;

$yamlarh = new Yamlarh(__DIR__.'/path/to/formatted/file');
$array = $yamlarh->parse();

Exemple

Variable injection

Variable injection is hierarchical, it will find in this order:

1. In the yaml file with import
2. In your global scope
3. In your constants
4. In accessible variables set in yamlarh

Yaml file:

arhframe:
  myvar1: test
  myvar2: %arhframe.myvar1%
  myvar3: %var3%
  myvar4: %VARCONSTANT%
  myvar5: %addedInYamlarh%

Or in xml:

<?xml version="1.0" encoding="UTF-8" ?>
<yamlarh>
    <arhframe>
        <myvar1>test</myvar1>
        <myvar2>%arhframe.myvar1%</myvar2>
        <myvar3>%var3%</myvar3>
        <myvar4>%VARCONSTANT%</myvar4>
        <myvar5>%addedInYamlarh%</myvar5>
    </arhframe>
</yamlarh>

Or in json:

{
  "arhframe": {
    "myvar1": "test",
    "myvar2": "%arhframe.myvar1%",
    "myvar3": "%var3%",
    "myvar4": "%VARCONSTANT%",
    "myvar5": "%addedInYamlarh%"
  }
}

Php file:

use Arhframe\Yamlarh\Yamlarh;
$var3 = 'testvar';
define('VARCONSTANT', 'testconstant');
$yamlarh = new Yamlarh(__DIR__.'/test.yml');
$yamlarh->addAccessibleVariable("addedInYamlarh", "var added");
$array = $yamlarh->parse();
echo print_r($array);

Output:

  Array
  (
      [arhframe] => Array
          (
              [myvar1] => test
              [myvar2] => test
              [myvar3] => testvar
              [myvar4] => testconstant
              [myvar5] => var added
          )
  )

Object injection

It use snakeyml (yaml parser for java) style:

arhframe:
  file: !! Arhframe.Util.File(test.php) #will instanciate this: Arhframe\Util\File('test.php') in file var after parsing

Import

Import are also hierarchical the last one imported will override the others.

Use yar-import by default in your file:

file1.xml

<?xml version="1.0" encoding="UTF-8" ?>
<yamlarh>
    <arhframe>
        <var1>var</var1>
    </arhframe>
    <test>arhframe</test>
    <yar-import>file2.yml</yar-import> <!-- you can use a relative path to your yaml file or an absolute -->
</yamlarh>

file2.yml

arhframe:
  var1: varoverride
test2: var3

After parsing file1.xml, output will look like (just to have a better format it's show yml):

arhframe:
  var1: varoverride
test: arhframe
test2: var3

Include

You can include a yaml file into another:

file1.yml

arhframe:
  var1: var
test:
  yar-include:
    - file2.yml #you can use a relative path to your yaml file or an absolute

file2.yml

test2: var3

After parsing file1.yml, output will look like:

arhframe:
  var1: var
test:
  test2: var3

Note: You can look at these tests to know what you can also do.

Extensible

Add a node

After parsing and importing but before injecting yamlarh can run your extension.

You have to create a new class which extends Arhframe\Yamlarh\YamlarhNode and add it to your yamlarh instance like this:

//create your yamalarh instance before
$yamlarh->addNode("myNodeName", new MyYamlarhNode());

Now you can use (for this example) yar-myNodeName in your formated file.

Note: the yar-include is a node take look at IncludeYamlarhNode to have a good example.
