I've begun work on a JavaScript (well, CoffeeScript) implementation of ChucK, ChucKJS, for which I'm seeking feedback from ChucK developers in particular. Web Audio API is used to produce sound. Very little of the language is implemented so far, I've just today finished end-to-end support (including a VM) for playing back a sine tone for a certain interval of time as in the following program:

    SinOsc sin => dac;

    2::second => now;

Even though this may seem minor, I'm pretty happy that this is at all possible just from within the browser :) As explained in the project's README, there is a self-contained example (examples/example1.html) which demonstrates the aforementioned sine wave playback capability.

What do you guys think, are anyone else interested in being able to run ChucK programs in the browser? Anyone interested in helping out on ChucKJS (like ChucK it's GPL licensed)?

My motivation for writing ChucKJS is to develop an online development environment for ChucK where one can execute the programs directly in the browser, I figure this will lower the threshold and make the language more fun to work with.

Merry Christmas,
