Here's the annotated source code:

It was mentioned on a Changelog interview earlier today, so I figured it would be good to put up:

needs web workers for some multicore sweetness!

jashkenas4• 16 years ago

That would be fantastic. You can't touch the DOM (or the canvas) through a webworker, so you'd have to serialize your list of exposure updates, and pass them around between the cores somehow...

Yeah, adding shared memory byte arrays to web workers would be really great for data-intensive tasks such as this. Anyone up for massaging the spec group? ;)

As cool as I think CoffeeScript is, the annotated source examples are really my favorite part of the language.

Well that was a fun way to crash my browser.

Just give it some time. After approx 5mins my firefox came back to life.

...yeah, its slow. And Firefox really needs to get a multitasking scheduler or something

Or try it in Chrome, and be amazed by just how different it feels -- not just to have V8, but to have it in a separate process.

If you like Buddhabrot, a friend of mine used MapReduce to create a high-res image of Buddhabrot's cousin: Nebulabrot. Kinda fun.

CoffeeScript's creators / users (which is this one?) have been a source for some of the best code annotations I've ever seen. Here's hoping they keep up the epic work!

There's now a little family of quick and dirty documentation generators, a-la Docco (the program used here):

Docco (CoffeeScript) http://jashkenas.github.com/docco/

Rocco (Ruby) http://rtomayko.github.com/rocco/

Pycco (Python) http://fitzgen.github.com/pycco/

Schocco (POSIX Shell) http://rtomayko.github.com/shocco/

Lo-fi literate programming for the rest of us...
