Hello all,

I have a CGI::Application webapp in which I would like to dynamically include template file names based on context (specifically, which of several policies might apply to the end user).

Taking cues from the sources listed below, this seemed a trivial task; create a text substitution code reference and feed that to the filter option. However, I cannot get it to work, even after stripping down to the most basic test case.

Sources

My template test file (magic-tmpl.html):

<p>Where's the magic?</p>
!!!blargle!!!

[download]

My test code:

#!/usr/bin/perl

use Modern::Perl;
use HTML::Template;

# This is the part that would be context-driven, if it worked...
my $policy_file = 'test-policy.html';

my $magic = sub {
    my $textref = shift;
    $textref =~ s/!!!blargle!!!/<tmpl_include $policy_file>/g;
};

my $t = HTML::Template->new( 
    filename => '/web/filter/data/magic-tmpl.html', 
    filter => $magic
);

say $t->output;

__END__

Produces:
<p>Where's the magic?</p>
!!!blargle!!!

Obviously, the desired substitution is not occuring. If anyone can help me locate the appropriate fairy dust for this kind of magic, I should be very grateful. I am hoping for a solution within CGI::Application and HTML::Template, but would consider other frameworks as needed. Thank you for your time.
