Regexp::Common::delimited.3pm

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}{-esc}

$RE{delimited}{-delim}{-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.

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'
 
 

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

$1

captures the entire match

$2

captures the opening delimiter (provided only one delimiter was specified)

$3

captures delimited portion of the string (provided only one delimiter was specified)

$4

captures the closing delimiter (provided only one delimiter was specified)

$RE{quoted}{-esc}

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