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";
(For more on Regexp::Assemble see: Why machine-generated solutions will never cease to amaze me.)
HTH,

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).

or How to display code and escape characters
are good places to start.
