Using a custom TT filter

Hi,

I am trying to use a custom TT filter in a Catalyst app.

In MyApp.pm I use:

'View::TT' => {
PLUGIN_BASE => __PACKAGE__->path_to('lib'),
},

In the lib dir I have a Diverse/NoDia.pm module that looks
like this:

package Diverse::NoDia;

use Template::Plugin::Filter;
use base 'Template::Plugin::Filter';

sub filter {
my ($self, $text) = _;
$text =~ tr/ãºþîâêÞÎÂ/astiaASTIA/;
return $text;
}
1;

In the template I use:

[% USE NoDia = Diverse.NoDia -%]
[% FILTER $NoDia -%]
...
[% END %]

But it gives the following error:

Couldn't render template "plugin error - Can't locate
object method "load" 
via package "D:webTranzactiiBursierelib:iverse::
NoDia" (perhaps you 
forgot
to load "D:webTranzactiiBursierelib:iverse::
NoDia"?) at 
D:/usr/site/lib/Template/Plugins.pm line 215.
"

How can I define a custom TT filter in a Catalyst app?

(I need to filter a text depending on a condition, and I
don't know if I can 
use another method for doing this.)

Thank you.


Octavian

Not strictly a Catalyst question, but my guess is you're
using
PLUGIN_BASE incorrectly.

According to 'perldoc Template::Plugin' (which of course
you've already
read):


   Use the PLUGIN_BASE option to specify the namespace that
you use.  e.g.

       use Template;
       my $template = Template->new({
           PLUGIN_BASE => ’MyOrg::Template::Plugin’,
       });

You're not specifying a namespace, you're giving a path ...

Hello,

In your TT::View you could add:

use base 'Catalyst::View::TT';

sub noDia {
     my $text = shift;
     $text =~ tr/ăşţîâĂŞŢÎÂ/astiaASTIA/;
     return $text;
}

__PACKAGE__->config({
     FILTERS => {
         'noDia' => &noDia,
     },
});

So, in your template you should be able to use:

[% FILTER noDia -%]
data to parse
[% END %]


I hope this helps. This is just form my knowledge of TT. I'm
still  
getting used to Catalyst so someone else might have a better
idea but  
its worth a try ;)

my answer has nothing to do with that – but:

Have you seen Text::Unidecode?
