JavaScript (CoffeeScript) parser for the ChucK music programming language, for execution within browsers supporting the Web Audio API (e.g. Chrome, Firefox).

This project is merely in its infancy at this stage, so don't expect too much at this point. For example, error checking is non-existent. We're basically at the point of having implemented a minimal part of the language, just enough to be able to execute the official examples we have ported so far.

To see (or perhaps more importantly, hear) ChucKJS in practice, please visit our ChucK Demos site, which aggregates and lets you play back language demos.

Focus has shifted to an attempt to automatically port ChucK to JavaScript, using the Emscripten tool. See my ChucK fork if you'd like to follow its progress, or perhaps even contribute.

In order to build ChucKJS, you'll need an installation of Node along with NPM. If you haven't already installed Grunt, install it system-wide:

npm install -g grunt-cli

Then, within the ChucKJS project root, install its dependencies (beneath the project root) via NPM:

npm install

After doing this, you should be able to build ChucKJS, by running grunt:

grunt

At this point, the parser has been built as lib/chuck/parser.js. CoffeeScript source files (in src/) are also compiled to JavaScript beneath lib/. Additionally, ChucKJS and its dependencies are built into the file examples/js/chuck.js, for the benefit of the examples within the examples/ directory. At this stage, you should be able to try the examples, e.g. examples/example1.html.

There are self-contained example HTML files beneath the examples/ directory, which you are encouraged to try out. In addition to these, ChucKJS is automatically tested via Karma. Run these tests as follows:

karma start
