There are basically just two things you'll need to worry about:
1) The script that processes your template (or the startup.pl
script, if you're using mod_perl) will have to have a
'use lib' line pointing to the place where you want to store
your custom plugins.
2) The Template object will have to be configured to know about
your plugins' namespace, via the PLUGIN_BASE configuration
option.
So, let's say you have a script called /home/me/myscripts/render.pl
and you have a plugin CoolPlugins::ValidDate that lives at
/home/me/myplugins/CoolPlugins/ValidDate.pm . In your template
(which is process()'ed by render.pl in this example), you want to be
able to use your plugin as follows:
[% USE ValidDate %]
[% IF ValidDate.check(date_first_pub) %]
date_first_pub is a valid ISO8601 date
[% ELSE %]
where'd you dig up that funky date format?
[% END %]
In /home/my/myscripts/render.pl:
#!/usr/bin/perl
use strict;
use lib qw(/home/me/myplugins);
use Template;
my $tt = new Template( { PLUGIN_BASE => 'CoolPlugins' } );
... etc.
The key pieces are the 'use lib' line and the PLUGIN_BASE config
option in the Template instantiation. The former helps Perl (and by
extension, TT) find your module and the latter lets you USE it in
your template without the having to call it CoolPlugins.ValidDate.
Hope that helps.
