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:
template: HtmlTemplate
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 `' generated by the
scaffolding script must be updated to use HTML::Template directives:
[% content %]
needs to be changed to:
<!--tmpl_var name="content"-->
<TMPL_VAR name="content">
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 `.tt'.
If you want to change the extension used, use the `extension'
configuration option, for example, to declare that the extension should
be `.tmpl':
template: 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
For instance, the session contents are passed to Dancer templates as
`session' - to access a key of that hashref named `username', you'd say:
<TMPL_VAR name="session.username">

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.
