Defined in:
lib/frank/tilt.rb

Overview

Erubis template implementation. See: www.kuwata-lab.com/erubis/

ErubisTemplate supports the following additional options, which are not passed down to the Erubis engine:

:engine_class   allows you to specify a custom engine class to use
                instead of the default (which is ::Erubis::Eruby).

:escape_html    when true, ::Erubis::EscapedEruby will be used as
                the engine class instead of the default. All content
                within <%= %> blocks will be automatically html escaped.
