Hello,
I've integrated CodeMirror (http://codemirror.net/) in index.html, so users can try to macro expand their own snippets.
You can see it at work here: http://voila.github.com/sweet.js/
I've added expander.js, parser.js and sweet.js to browser/scripts, in order to get it to work. Hope that's all right.
