And you beat me to whipping up a solution, though plugging your regex into my test proves that your regex works for the test cases I was able to think up:

#!/usr/bin/perl use strict; use warnings; my @input = ( "cocks are roosters!", "my cocks crow at dawn", "i'm a fan of the cocks", "game cocks all the way!", "do you like the gamecocks?" ); my $vulgar_list = { cocks => { regex => qr/(?<!a)(?<!the)(?<!game)(?<!\s)\s*coc +k/ } }; my $foundvulgar; for my $input( @input ){ study($input); foreach my $word (keys %$vulgar_list) { my $regex = $vulgar_list->{$word}->{regex}; if ($input =~ m/$regex/) { $foundvulgar = $word; last; } } print "phrase: $input found?: $foundvulgar\n"; $foundvulgar = ''; } __OUPUT__ phrase: cocks are roosters! found?: cocks phrase: my cocks crow at dawn found?: cocks phrase: i'm a fan of the cocks found?: phrase: game cocks all the way! found?: phrase: do you like the gamecocks? found?:

s**lil*; $*=join'',sort split q**; s;.*;grr; &&s+(.(.)).+$2$1+; $; = qq-$_-;s,.*,ahc,;$,.=chop for split q,,,reverse;print for($,,$;,$*,$/)

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
