=head1 DESCRIPTION
This class is an interface between Dancer's template engine abstraction layer
and the L<Text::Xslate> module.
In order to use this engine, use the template setting:
template: xslate
This can be done in your config.yml file or directly in your app code with the
B<set> keyword.
You can configure L<Text::Xslate>:
template: xslate
engines:
xslate:
cache_dir: .xslate_cache/
cache: 1
extension: tx # Dancer's default template extension is "tt"
module:
- Text::Xslate::Bridge::TT2Like # to keep partial compatibility with Template Toolkit
