Liquid.coffee was ported from a fork of liquid 2.2.2, after which the following additions were made:
This library was created as a plugin for huginn and named huginn-liquid. It is still available on npmjs.org under that name. This site was generated with huginn using liquid.coffee. Since then, I've added a browserified distribution under the name liquid.coffee.js, which is suitable for use in single page apps. Examples of this usage can be found in the Frodo app.
$ cd <project name>
$ npm install liquid.coffee --save
$ npm install liquid.coffee
$ npm test
$ npm install liquid.coffee
$ cake build:src
