Reference

apache-notice

No inputs. Checks for the presense of a NOTICE file in the root of the repository. This rule is equivalent to the following:

{
  "type": "file-existence",
  "options": {"globsAny": ["NOTICE*"]}
}

directory-existence

Checks the existence of a given directory.

Input	Required	Type	Default	Description
globsAny	Yes	string[]		A list of globs to search for. This rule passes if at least one glob returns a directory.
nocase	No	boolean	false	Set to true to perform a case insensitive search.
fail-message	No	string	""	The string to print if the directory does not exist, used to create human-readable error messages.

file-contents

Checks if the contents of a file match a given regular expression.

Input	Required	Type	Default	Description
globsAll	Yes	string[]		A list of globs to get files for. This rule passes if all of the files returned by the globs match the supplied string, or if no files are returned.
content	Yes	string		The regular expression to check using String#search. This expression should not include the enclosing slashes and may need to be escaped to properly integrate with the JSON config (ex. ".+@.+\\..+" for an email address).
nocase	No	boolean	false	Set to true to make the globs case insensitive. This does not effect the case sensitivity of the regular expression.
flags	No	string	""	The flags to use for the regular expression in content (ex. "i" for case insensitivity).
human-readable-content	No	string	The regular expression in content	The string to print instead of the regular expression when generating human-readable output.
fail-on-non-existent	No	boolean	false	Set to true to disable passing if no files are found from globsAll.

file-existence

Checks the existence of a given file.

Input	Required	Type	Default	Description
globsAny	Yes	string[]		A list of globs to search for. This rule passes if at least one glob returns a file.
nocase	No	boolean	false	Set to true to perform a case insensitive search.
dirs	No	boolean	false	Set to true to include directories in the search (equivalent to directory-exists)
fail-message	No	string	""	The string to print if the directory does not exist, used to create human-readable error messages.

file-hash

Checks that a given file matches a provided hash.

Input	Required	Type	Default	Description
globsAny	Yes	string[]		A list of globs to search for. This rule passes if at least one file found matches the provided hash, and fails if no files are found.
hash	Yes	string		The hash to check against. Unless a different algorithm is specified, this will be sha256 hash.
algorithm	No	string	sha256	The hash algorithm to use. Repolinter supports any algorithm supported by crypto.createHash
nocase	No	boolean	false	Set to true to perform a case insensitive search.
succeed-on-non-existent	No	boolean	false	Set to true to enable passing if no files are found from globsAll.

file-hashes-not-exist

Check files' hashes not included in a list of certain cryptographic hashes.

Input	Required	Type	Default	Description
globsAll	Yes	string[]		A list of globs to search for. This rule passes if all the files does not match any of the hashes, or no files are found.
hashes	Yes	string[]		The hashes to check against. Unless a different algorithm is specified, this will be sha256 hash.
algorithm	No	string	sha256	The hash algorithm to use. Repolinter supports any algorithm supported by crypto.createHash
nocase	No	boolean	false	Set to true to perform a case insensitive search.

file-no-broken-links

Scans a set of markup files for broken links. Links are tested by first rendering the markup file to HTML using github-markup, then each <a> tag in the HTML is extracted and tested using broken-link-checker--as a result, this rule only supports checking markup formats supported by github-markup. Absolute URLs are checked using a HTTP request, and relative URLs are checked by accessing the file specified.

github-markup and its dependencies must be installed and available in PATH to use this rule.

Input	Required	Type	Default	Description
globsAll	Yes	string[]		A list of globs to search for. This rule passes if all of the markup files found do not contain broken links.
nocase	No	boolean	false	Set to true to perform a case insensitive search.
succeed-on-non-existent	No	boolean	false	Set to true to enable passing if no files are found from globsAll.
pass-external-relative-links	No	boolean	false	Set to true to allow relative URLs outside of the target directory. As there is no good way to check these URLs, they will automatically pass if this setting is true.

file-not-contents

Checks none of a given list of files match a given regular expression.

Note: provide either content or contents

Input	Required	Type	Default	Description
globsAll	Yes	string[]		A list of globs to get files for. This rule passes if none of the files returned by the globs match the supplied string, or if no files are returned.
content	Yes if contents is undefined	string		The regular expression to check using String#search. This expression should not include the enclosing slashes and may need to be escaped to properly integrate with the JSON config (ex. ".+@.+\\..+" for an email address).
contents	Yes if content is undefined	string[]		Regular expressions to check using String#search. This expression should not include the enclosing slashes and may need to be escaped to properly integrate with the JSON config (ex. ".+@.+\\..+" for an email address).
nocase	No	boolean	false	Set to true to make the globs case insensitive. This does not effect the case sensitivity of the regular expression.
flags	No	string	""	The flags to use for the regular expression in content (ex. "i" for case insensitivity).
human-readable-content	No	string	The regular expression in content	The string to print instead of the regular expression when generating human-readable output.
fail-on-non-existent	No	boolean	false	Set to true to disable passing if no files are found from globsAll.

file-not-exists

Checks that a file doesn't exist.

Input	Required	Type	Default	Description
globsAll	Yes	string[]		A list of globs to search for. This rule fails if at least one glob returns a file.
nocase	No	boolean	false	Set to true to perform a case insensitive search.
dirs	No	boolean	false	Set to true to include directories in the search.
pass-message	No	string	""	The string to print if the file does not exist, used to create human-readable error messages.

file-starts-with

Checks that the first lines of a file contain a set of regular expressions.

Input	Required	Type	Default	Description
globsAll	Yes	string[]		A list of globs to search for. This rule passes if the starting contents of all found files match all patterns, and fails if no files are found.
lineCount	Yes	number		The number of lines to scan into for each file.
patterns	Yes	string[]		The regular expressions to check using String#search. These expressions should not include the enclosing slashes and may need to be escaped to properly integrate with the JSON config (ex. ".+@.+\\..+" for an email address).
flags	No	string	""	The flags to use for the regular expressions in patterns (ex. "i" for case insensitivity).
nocase	No	boolean	false	Set to true to perform a case insensitive search on the files. This will not effect the case sensitivity of patterns.
succeed-on-non-existent	No	boolean	false	Set to true to enable passing if no files are found from globsAll.
skip-binary-files	No	boolean	false	Set to true to exclude binary files from globsAll.
skip-paths-matching	No	{ extensions?: string[], patterns?: string[], flags?: string }	{}	Use this option to exclude paths from globsAll, either by file extension or by regular expression.

file-type-exclusion
