Regexp::Common::lingua(3pm) User Contributed Perl Documentation Regexp::Common::lingua(3pm)
NAME
Regexp::Common::lingua -- provide regexes for language related stuff.
SYNOPSIS
use Regexp::Common qw /lingua/;
while (<>) {
/^$RE{lingua}{palindrome}$/ and print "is a palindrome
";
}
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{lingua}{palindrome}
Returns a pattern that recognizes a palindrome, a string that is the same if you reverse it. By default, it only matches strings consisting
of letters, but this can be changed using the "{-chars}" option. This option takes a character class (default is "[A-Za-z]") as argument.
If "{-keep}" is used, only $1 will be set, and set to the entire match.
This pattern requires at least perl 5.6.0.
