FUNCTIONS
  get_regexp_pattern_pattern
    Usage:

     get_regexp_pattern_pattern(%args) -> [status, msg, payload, meta]

    Get a Regexp::Pattern::* pattern.

    Examples:

    *   Example #1:

         get_regexp_pattern_pattern(pattern => "YouTube/video_id"); # -> "(?^:[A-Za-z0-9_-]{11})"

    *   Generate variant A of Example::re3:

         get_regexp_pattern_pattern( pattern => "Example::re3", gen_args => { variant => "A" }); # -> "(?^:\\d{3}-\\d{3})"

    *   Generate variant B of Example::re3:

         get_regexp_pattern_pattern( pattern => "Example::re3", gen_args => { variant => "B" });

        Result:

         "(?^:\\d{3}-\\d{2}-\\d{5})"

    This function is not exported.

    Arguments ('*' denotes required arguments):

    *   gen_args => *hash*

        Supply generator arguments.

        If pattern is a dynamic pattern (generated on-demand) and the
        generator requires some arguments, you can supply them here.

    *   pattern* => *regexppattern::name*

        Name of pattern, with module prefix but without the
        'Regexp::Pattern'.

    Returns an enveloped result (an array).

    First element (status) is an integer containing HTTP status code (200
    means OK, 4xx caller error, 5xx function error). Second element (msg) is
    a string containing error message, or 'OK' if status is 200. Third
    element (payload) is optional, the actual result. Fourth element (meta)
    is called result metadata and is optional, a hash that contains extra
    information.

    Return value: (any)

  list_regexp_pattern_modules
    Usage:

     list_regexp_pattern_modules() -> [status, msg, payload, meta]

    List all installed Regexp::Pattern::* modules.

    This function is not exported.

    No arguments.

    Returns an enveloped result (an array).

    First element (status) is an integer containing HTTP status code (200
    means OK, 4xx caller error, 5xx function error). Second element (msg) is
    a string containing error message, or 'OK' if status is 200. Third
    element (payload) is optional, the actual result. Fourth element (meta)
    is called result metadata and is optional, a hash that contains extra
    information.

    Return value: (any)

  match_with_regexp_pattern
    Usage:

     match_with_regexp_pattern(%args) -> [status, msg, payload, meta]

    Match a string against a Regexp::Pattern pattern.

    Examples:

    *   A non-match:

         match_with_regexp_pattern(pattern => "YouTube/video_id", string => "foo");

        Result:

         "String DOES NOT match regexp pattern YouTube::video_id"

    *   A match:

         match_with_regexp_pattern(pattern => "YouTube/video_id", string => "Yb4EGj4_uS0");

        Result:

         "String matches regexp pattern YouTube::video_id"

    This function is not exported.

    Arguments ('*' denotes required arguments):

    *   anchor => *bool*

        Generate an anchored version of the pattern.

    *   captures => *bool*

        Return array of captures instead of just a boolean status.

    *   gen_args => *hash*

        Supply generator arguments.

        If pattern is a dynamic pattern (generated on-demand) and the
        generator requires some arguments, you can supply them here.

    *   pattern* => *regexppattern::name*

        Name of pattern, with module prefix but without the
        'Regexp::Pattern'.

    *   quiet => *bool*

    *   string* => *str*

    Returns an enveloped result (an array).

    First element (status) is an integer containing HTTP status code (200
    means OK, 4xx caller error, 5xx function error). Second element (msg) is
    a string containing error message, or 'OK' if status is 200. Third
    element (payload) is optional, the actual result. Fourth element (meta)
    is called result metadata and is optional, a hash that contains extra
    information.

    Return value: (any)
