Warm greetings from the backwoods of Pennsylvania.

I've created a very simplistic example that should illustrate my question. Basicaly what I'm trying to do is have my loops interrupted at regular intervals.

If I were to do this in perl only, I'd have a main loop, with a test for "if $count % 2". If that test was true, I'd do the special operations and then continue.

However, working in Template Toolkit, I don't seem to have access to the modulus operator (or, I don't understand the syntax for IF). When the following template runs, I get nothing. When I take the 'IF' block out, I get my list, but of course without the separators which I'm trying to get.

How would one go about making an insertion at a regular interval?

Update: I am embarrased to admit that I fell for the old '=' vs. '==' trick. rafl hit it right away. I'm trying to tell myself I missed it 'cause my eyes weren't looking for Perl syntax, but I'm still *really* ashamed.

Code fixed.

#!/usr/bin/perl
use strict;
$|++;

use Template;
my $tt  = Template->new;
my %data = (
    bar_every => 2,
    colors => [qw( red orange yellow green blue indigo violet silver g
+old )],
);
$tt->process(\*DATA, \%data);
exit;


#  To make the template below work (exept for inserting the bars),
#  Just delete or comment the 'IF' and the two following lines


__DATA__
[% cnt = 0 %]

We're going to print a bar every [% bar_every %] items.

[% FOREACH color = colors -%]
    [% cnt = cnt + 1 -%]
    [%cnt %] The color is [% color %].
    [% IF cnt % bar_every == 0 -%]
----
    [% END -%]
[% END -%]
