[chuck-dev] Fwd: Porting ChucK to JavaScript with Emscripten

Hi Phill!

First of all, you might want to check out the fruits of my existing
efforts, if you haven't already: ChucKJS (https://github.com/aknuds1/chuckjs)
and ChucK Demos (http://chuckdemos.com, this is based on ChucKJS).

Second, I have a fork of ChucK which I linked to in my original email:
https://github.com/aknuds1/chuck/tree/emscripten. The work goes on in the
emscripten branch. To build this, you must have sourced the Emscripten SDK
(the whole thing is a bit ramshackle for now, sorry about that) and type
"make emscripten".

Sure you're welcome to help out! Can you write C++? The project is C++
driven, since the idea is to transform ChucK sources (in C++) to JavaScript
automatically. Right now, I mainly need to write Emscripten shims
(emulations) of ChucK dependencies such as the audio driver (I'm currently
thinking we should emulate ASIO).

Otherwise, we will probably need some JavaScript ("unit") tests down the
line to verify that e.g. the shims do what they're supposed to.
