Running Gists like a JsFiddle
After working with AngularJS, which is totally awesome, I wanted a better way to share code snippets with the community. Something where the header declarations aren't hidden, so it's clear which version of angular you're using and whether zepto/jquery/underscore are loaded. I also wanted to use CoffeeScript, HAML and SCSS because that's what I use to write Goodfilms (my day job).
This HTML is being rendered from HAML, the CSS is being compiled from SCSS, the JS code is written in Coffeescript and even this here text is being compiled (in the browser) from a gist-hosted Markdown file.
