Emblem.js

p Introducing Emblem.js: a new templating language
  that compiles to Handlebars.js

ul
  li Indentation-based (like Slim, Jade, HAML, etc.)
  li Compiles to Handlebars; full compatibility with
     both custom and built-in Handlebars helpers
  li Ember.js-friendly syntax and full compatibility
     with auto-updating functionality.

/ Emblem is HTML5-aware; Render HTML if a line starts with
  known HTML tag, else invoke HB helper or perform property lookup.
  These defaults are easily overridable when necessary.
ul
  each person in people
    li = person.name

section.ember-features
  / easy, natural Ember bindAttr support
  h1 class=foo The class name of this element is bound to `foo`
  p class=isActive:flashing:inactive Ember.js bound css classes

  / implicit Ember action handlers
  a click="doIt" href="#" Hello, how are you doing, #{name}?

/ condense nested content into a single line if that's how you roll
#footer: ul.menu-items: each menu_items: li: a.menu-link href=url: link_text

if something
  p something was true!
else 
  p something was false!
