Properly formatting JavaScript in JavaScript

Question

How can I automatically format JavaScript properly?

As an example, this:

(function(){(function(){alert('whatever')})()})()

Should become:

(function(){
    (function(){
        alert('whatever')
    })()
})()

jsfiddle.net has a "tidyup" option - maybe it's open source based? — Alnitak

Python based? The one I saw is written in Javascript.

Try http://jsbeautifier.org/ - it's the same one used by jsfiddle.net on their "Tidy Up" button where you can try it out.
