NAME
Regexp::Common::profanity -- provide regexes for profanity SYNOPSIS
use Regexp::Common qw /profanity/; while (<>) { /$RE{profanity}/ and print "Contains profanity "; } 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{profanity} Returns a pattern matching words -- such as Carlin's "big seven" -- that are most likely to give offense. Note that correct anatomical terms are deliberately not included in the list. Under "-keep" (see Regexp::Common): $1 captures the entire word $RE{profanity}{contextual} Returns a pattern matching words that are likely to give offense when used in specific contexts, but which also have genuinely non- offensive meanings. Under "-keep" (see Regexp::Common): $1 captures the entire word SEE ALSO
