regexp::common::list
Regexp::Common::list(3) User Contributed Perl Documentation Regexp::Common::list(3)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=>" "} # match a tab-separated list
$RE{list}{-lastsep=>',s+ands+'} # 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*PATTERNs*'}
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'}
