Dancer::Template::Abstract - abstract class for Dancer's template engines
This class is provided as a base class for each template engine. Any template engine must inherit from it and provide a set of methods described below.
The template engine can overload this method if some initialization stuff has to be done before the template engine is used.
The base class provides a plain init() method that only returns true.
This method must be implemented by the template engine. Given a template and a set of tokens, it returns a processed string.
If $template is a reference, it's assumed to be a reference to a string that contains the template itself. If it's not a reference, it's assumed to be the path to template file, as a string. The render method will then have to open it and read its content (Dancer::FileUtils::read_file_content does that job).
$template
This method's return value must be a string which is the result of the interpolation of $tokens in $template.
$tokens
If an error occurs, the method should trigger an exception with die().
die()
Examples :
# with a template as a file $content = $engine->render('/my/template.txt', { var => 42 }; # with a template as a scalar my $template = "here is <% var %>"; $content = $engine->render(\$template, { var => 42 });
