Defined in:
lib/tilt/liquid.rb

Overview

Liquid template implementation. See: liquid.rubyforge.org/

Liquid is designed to be a safe template system and threfore does not provide direct access to execuatable scopes. In order to support a scope, the scope must be able to represent itself as a hash by responding to #to_h. If the scope does not respond to #to_h it will be ignored.

LiquidTemplate does not support yield blocks.

It's suggested that your program require 'liquid' at load time when using this template engine.
