A Titanium Mobile API parser made with Ruby, it takes api.json file and dumps a SDOC file, now, add the SDOC file to your NetBeans project (I guess it works on Aptana) then you have code completation of the API, yay! :D.
Download API Reference as JSON (api.json) from here, move it to dist/api.json, then run default task:
$ rake
It creates a SDOC file in the dump/ folder.
Copy dump/titanium-mobile.sdoc file to your project.
- I don't know why the comments doesn't work, still, methods, params, etc, works fine.
