Re: One line assigment statement with regex match

This looks like a good case for Regex::Presuf i.e

use Regex::PreSuf;

my $lineFromSomeTextFile = "your line right here\n";
my @terms                = qw/ something matching a line /;
my($word) = $lineFromSomeTextFile =~ /(${\presuf(@terms)})/;
# or without PreSuf
my($word) = $lineFromSomeTextFile =~ do {local $" = '|'; "(@terms)"};

print "found '$word' in: $lineFromSomeTextFile";

__output__

found 'line' in: your line right here

Just because I really like grinder's Regexp::Assemble, and think such a cool module needs more exposure: `#!/usr/bin/perl -w use Regexp::Assemble; my $lineFromSomeTextFile = "your line right here\n"; my $ra = Regexp::Assemble->new->add( "something", "matching", "a", "line" ); print $ra->re . "\n"; # because the output is cool # and sometimes educational my($word) = $lineFromSomeTextFile =~ /($ra)/; print "found '$word' in: $lineFromSomeTextFile";` [download] (For more on Regexp::Assemble see: Why machine-generated solutions will never cease to amaze me.)
