[Dancer-users] Custom FILTERS for TemplateToolkit in dancer?

[Matthew Vickers]

Hi Assaf,

I could be completely off base, and please tell me if I am, when I need to use custom code in the template I use 

before_template sub {
    my $tokens = shift;
    $tokens->{'my_custom_filter'} = &custom_filter;
};

Then I call the custom helper in the template like so

<h1><% custom_filter("Hello World") %></h1>

I have written a basic post here:

Cheers

Matt
