Fu

Fu combines the logic–less portability of Mustache with the terse utility of Haml. This is what it looks like:

%ul
  {{#children}}
    %li {{name}}

Then in the (Sinatra) app:

get "/list" do
  fu :list, :locals => {:children => [{:name => "Arne"}, {:name => "Bjarne"}]}
end

And you get:

<ul><li>Arne</li><li>Bjarne</li></ul>

A contrived example using all aspects of the syntax:

%h1 Hello, {{user_name}}
%p.text
  This is a paragraph of 
  text.    
%ul.friend_list(data-attribute1="some data", data-attribute2="{{some_mustache_data}}")
  {{#friends}}
    %li
      {{>friend_partial}}
  {{^friends}}
    %p.error
      You, unfortunately, have no friends.

Usage

Direct:

Fu.to_mustache("%p Hello {{mustache}}")

With Sinatra and Tilt:

require 'fu/tilt'

Stick your fu-templates in your views-folder with the extension .fu.

Then, in your app:

get "/some_action" do
  fu :some_template, :locals => {...}
end
