I'm trying to build a hash of possible substitutes for a given word or regex. So, I came up with this.
#!/usr/bin/perl
use strict;
my $test = 'The brown fox int(10) over float(200) fence.';
my %dict = ( 'brown' => 'yellow',
/int(\d+)/ => 'int',
/float(\d+)/ => 'float',
);
for my $i (keys %dict) {
$test =~ s/($i)/$dict{$i}/gi;
}
print "$test\n";
This is the output.
The yellow fox float(10) over float(200) fence.
My expected output is something like this.
The yellow fox int over float fence.
So, I'm not sure if I can put regex in the keys of my hash and use that to check for possible substitutes. Also, why did int(10) become float(10) in the output??

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).
