Handlebars.rb

This uses therubyracer to bind to the actual JavaScript implementation of Handlebars.js so that you can use it from ruby.

Usage

Simple stuff

require 'handlebars'
template = Handlebars.compile("{{say}}{{what}}")
template.call(:say => "Hey", :what => "Yuh!") #=> "Hey Yuh!"

With functions as properties

template.call(:say => "Hey", :what => lambda {|this| ("yo" * 2) + "!"}) #=> "Hey yoyo!"

Register block helpers:

Handlebars.register_helper(:twice) do |block|
  "#{block.call}#{block.call}"
end
template = Handlebars.compile({{#twice}}Hurray!{{/twice}})
template.call #=> Hurray!Hurray!

Hack

git clone git@github.com:cowboyd/handlebars.rb.git #git it
cd handlebars.rb #go to it
git submodule update --init #pull down handlebars.js
rspec spec/ #test it

Rubygems

Handlebars is available via the [hbs](http://rubygems.org/gems/hbs) gem on rubygems.org. There
is an [abandoned](https://github.com/MSch/handlebars-ruby) pure-ruby implementation of handlebars
on github. Eventually, I'd like to merge these two projects, but I have not been able to contact the
owner of that gem.
