Dancer::Template::HtmlTemplate - HTML::Template wrapper for Dancer
This class is an interface between Dancer's template engine abstraction layer and the HTML::Template module.
In order to use this engine, use the template setting:
This can be done in your config.yml file or directly in your app code with the set keyword.
Since HTML::Template uses different syntax to other template engines like Template::Toolkit, the default layout
main.tt generated by the scaffolding script must be updated to use HTML::Template directives:
[% content %]
needs to be changed to:
Future versions of Dancer may ask you which template engine you wish to use, and write the default layout and example templates appropriately.
Also, the current default file extension for template files is
.tt; at the time this template engine wrapper was produced, the template engine wrapper could not override default file extensions. This is now possible, but I haven't made this change as it would break applications relying on the default being
If you want to change the extension used, use the
extension configuration option, for example, to declare that the extension should be
template: HtmlTemplate engines: HtmlTemplate: extension: 'tmpl'
WARNING - Even if you use the default
.tt, you may want to explictly set the
extension setting to indicate that, as future versions may default to a more suitable file extension.
Handling nested hashrefs
Since HTML::Template does not allow you to access nested hashrefs (at least, not without switching to using HTML::Template::Pluggable along with HTML::Template::Plugin::Dot), this module "flattens" nested hashrefs.
For instance, the session contents are passed to Dancer templates as
session - to access a key of that hashref named
username, you'd say:

Thanks to Damien Krotkine for providing code to flatten nested hashrefs in a way that allows HTML::Template templates to make use of them.
This module is free software and is released under the same terms as Perl itself.
