This is a great little program!
I couldn't resist speeding
it up a bit. A commonly used trick in
search engines is to
shift everything to upper case.
Avoiding the i
flag in the regular expression roughly doubles
the speed, on my machine at least.
I also used Storable to create a slightly faster-loading
dictionary.
#!/usr/bin/perl -w
use strict;
use Storable;
my $search_word = uc shift
or die "search word required\n";
my @words = ();
my @dict;
my $rdict;
my $count = 0;
if (not -e 'words.sto') {
open WORDS, '/usr/share/dict/words'
or die "can't open words file\n";
while (<WORDS>) {
chomp;
push @dict, uc $_;
}
close WORDS;
$rdict= \@dict;
store $rdict, 'words.sto';
}
else {
$rdict= retrieve('words.sto');
}
for (@$rdict) {
printf "%3d %s\n", ++$count, $_ if $search_word =~ /$_/;
}
It should work perfectly the first time! - toma

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).
