NAME

       Regexp::Common::delimited -- provides a regex for delimited strings

SYNOPSIS

           use Regexp::Common qw /delimited/;

           while (<>) {
               /$RE{delimited}{-delim=>'"'}/  and print 'a \" delimited string';
               /$RE{delimited}{-delim=>'/'}/  and print 'a \/ delimited string';
           }

DESCRIPTION

       Please consult the manual of Regexp::Common for a general description of the works of this interface.

       Do not use this module directly, but load it via Regexp::Common.

   $RE{delimited}{-delim}{-cdelim}{-esc}
       Returns a pattern that matches a single-character-delimited substring, with optional internal escaping of
       the delimiter.

       When "-delim =" S> is specified, each character in the sequence S is a possible delimiter. There is no
       default delimiter, so this flag must always be specified.

       By default, the closing delimiter is the same character as the opening delimiter. If this is not wanted,
       for instance, if you want to match a string with symmetric delimiters, you can specify the closing
       delimiter(s) with "-cdelim =" S>. Each character in S is matched with the corresponding character
       supplied with the "-delim" option. If the "-cdelim" option has less characters than the "-delim" option,
       the last character is repeated as often as necessary. If the "-cdelim" option has more characters than
       the "-delim" option, the extra characters are ignored.

       If "-esc =" S> is specified, each character in the sequence S is the delimiter for the corresponding
       character in the "-delim=S" list.  The default escape is backslash.

       For example:

          $RE{delimited}{-delim=>'"'}               # match "a \" delimited string"
          $RE{delimited}{-delim=>'"'}{-esc=>'"'}    # match "a "" delimited string"
          $RE{delimited}{-delim=>'/'}               # match /a \/ delimited string/
          $RE{delimited}{-delim=>q{'"}}             # match "string" or 'string'
          $RE{delimited}{-delim=>"("}{-cdelim=>")"} # match (string)

       Under "-keep" (See Regexp::Common):

       $1  captures the entire match

       $2  captures the opening delimiter

       $3  captures delimited portion of the string

       $4  captures the closing delimiter

   $RE{quoted}{-esc}
       A synonym for "$RE {delimited} {-delim => q {'"`}} {...}".

   $RE {bquoted} {-esc}
       This is a pattern which matches delimited strings, where the delimiters are a set of matching brackets.
       Currently, this comes 85 pairs. This includes the 60 pairs of bidirection paired brackets, as listed in
       <http://www.unicode.org/Public/UNIDATA/BidiBrackets.txt>.

       The other 25 pairs are the quotation marks, the double quotation marks, the single and double pointing
       quoation marks, the heavy single and double commas, 4 pairs of top-bottom parenthesis and brackets, 9
       pairs of presentation form for vertical brackets, and the low paraphrase, raised omission, substitution,
       double substitution, and transposition brackets.

       In a future update, pairs may be added (or deleted).

       This pattern requires perl 5.14.0 or higher.

       For a full list of bracket pairs, inspect the output of "Regexp::Common::delimited::bracket_pair ()",
       which returns a list of two element arrays, each holding the Unicode names of matching pair of
       delimiters.

       The "{-esc => S }" works as in the "$RE {delimited}" pattern.

       If "{-keep}" is given, the following things will be captured:

       $1  captures the entire match

       $2  captures the opening delimiter

       $3  captures delimited portion of the string

       $4  captures the closing delimiter
