Yes, you will definitely need string eval here.
Something like this:
#!/usr/bin/perl -w
use strict;
# builtin triggers
my %triggers;
# add triggers from params
my $trigger_name = shift @ARGV;
my $trigger_action_str = shift @ARGV;
$triggers{$trigger_name} = $trigger_action_str;
my $buff = "You are fired!";
foreach my $trigger ( keys ( %triggers ) )
{
if ( $buff =~ /$trigger/ )
{
print eval '"' . $triggers{$trigger} . '\n"';
}
}
But this is not a design anyone will recommend.
Besides, this will not run in taint mode.

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).
