I have two questions regarding the use of filters. I use the Template
Toolkit via ttree rather than writing custom Perl code that uses the
underlying modules. First question: Is it possible to define and use
custom filters via ttree?
No, not directly from ttree. But you can define filters using a plugin.
package Template::Plugin::MyFilters;
use base 'Template::Plugin';
sub new {
my ($class, $context) = @_;
$context->define_filter( name => sub { ... } );
}
Then put a [% USE MyFilters %] directive at the top of a PRE_PROCESS
template. The plugin will be loaded and the filters defined.
[% FILTER html_entity | wrap(95) | indent("\t") %]
That doesn't work I'm afraid, and it's too hard to fix it in the current
parser.
It is planned for TT3, although '+' will be the delimiting character (as
per PROCESS, INCLUDE etc which currently accept this form)
[% FILTER html_entity + wrap(95) + indent("\t") %]
...
[% END %]
Cheers
