Template::AutoFilter(3) Template::Toolkit with automatic filtering


version 0.143050


use Template::AutoFilter;
my $templ = "[% str %] [% str | none %] [% str | url %]";
my $out;
Template::AutoFilter->new->process( \$templ, { str => '<a>' }, \$out );
print $out; # "&lt;a&gt; <a> %3Ca%3E"
my $out;
Template::AutoFilter->new( AUTO_FILTER => 'upper' )->process( \$templ, { str => '<a>' }, \$out );
print $out; # "<A> <a> %3Ca%3E"


Template::AutoFilter is a subclass of Template::Toolkit which loads a specific Parser that is subclassed from Template::Parser. It adds a filter instruction to each interpolation token found in templates loaded by the TT engine. Tokens that already have a filter instruction are left unchanged.

By default this automatic filter is set to be 'html', but can be modified during object creation by passing the AUTO_FILTER option with the name of the wanted filter.

Additionally a pass-through filter called 'none' is added to the object to allow exclusion of tokens from being filtered.

Lastly, if you have problems with the directives which get auto filters applied, you can see the Template::AutoFilter::Parser docs for how you can customize that.

WARNING: This module is highly experimental. I have not done a lot of testing and things might blow up in unexpected ways. The API and behavior might change with any release (until 1.0). If you'd like to see any changes implemented, let me know via RT, email, IRC or by opening a pull request on github.

Use at your own risk.



Pre-processes the parameters passed on to Template's new(). Adds the pass-through filter and creates the AutoFilter Parser.

All parameters passed to this new() will also be passed to the parser's new().
