Regexp::Common::list - phpMan

NAME
    Regexp::Common::list -- provide regexes for lists

SYNOPSIS
        use Regexp::Common qw /list/;

        while (<>) {
            /$RE{list}{-pat => '\w+'}/          and print "List of words";
            /$RE{list}{-pat => $RE{num}{real}}/ and print "List of numbers";
        }

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{list}{-pat}{-sep}{-lastsep}
    Returns a pattern matching a list of (at least two) substrings.

    If "-pat=*P*" is specified, it defines the pattern for each substring in
    the list. By default, *P* is "qr/.*?\S/". In Regexp::Common 0.02 or
    earlier, the default pattern was "qr/.*?/". But that will match a single
    space, causing unintended parsing of "a, b, and c" as a list of four
    elements instead of 3 (with "-word" being "(?:and)"). One consequence is
    that a list of the form "a,,b" will no longer be parsed. Use the pattern
    "qr /.*?/" to be able to parse this, but see the previous remark.

    If "-sep=*P*" is specified, it defines the pattern *P* to be used as a
    separator between each pair of substrings in the list, except the final
    two. By default *P* is "qr/\s*,\s*/".

    If "-lastsep=*P*" is specified, it defines the pattern *P* to be used as
    a separator between the final two substrings in the list. By default *P*
    is the same as the pattern specified by the "-sep" flag.

    For example:

          $RE{list}{-pat=>'\w+'}                # match a list of word chars
          $RE{list}{-pat=>$RE{num}{real}}       # match a list of numbers
          $RE{list}{-sep=>"\t"}                 # match a tab-separated list
          $RE{list}{-lastsep=>',\s+and\s+'}     # match a proper English list

    Under "-keep":

    $1  captures the entire list

    $2  captures the last separator

  $RE{list}{conj}{-word=*PATTERN*}
    An alias for $RE{list}{-lastsep=>'\s*,?\s**PATTERN*\s*'}

    If "-word" is not specified, the default pattern is "qr/and|or/".

    For example:

          $RE{list}{conj}{-word=>'et'}        # match Jean, Paul, et Satre
          $RE{list}{conj}{-word=>'oder'}      # match Bonn, Koln oder Hamburg

  $RE{list}{and}
    An alias for $RE{list}{conj}{-word=>'and'}

  $RE{list}{or}
    An alias for $RE{list}{conj}{-word=>'or'}
