Ok, so you're just writing tested javascript that doesn't make use of the Max API and using it in Max then?

I've been stubbing out the Max API using a little mock/stub library I put together, but you've got the basic gist. I've been testing my own class' functionality to make sure those work correctly and then using the resulting JS inside of Max. If you were interested in writing tests that exercised the Max API itself, I would give Rhino a shot. If you are able to get Rhino running inside of Max let me know because I think that could be awesome.

I talked to some c74 guys when i speak at http://code-control.com and showed them coffee script and talked about Node.

Lets see what they will do about it ( :

Hope they enjoyed the ideas, and pay me a beer after they get millionare
