Notes
This is part of the Javascript toolkit for seed which also includes JSDOC documentation toolkit and API documentation for Gnome seed bindings.
Design
Loosely based off the Yahoo Compressor Java library, using the JSToolkit tokenizer code. Since I hate running Java anywhere, this is a pure Javascript solution, which in theory could be turned into an online version..
It's used primarily for the Roo javascript library building and my Pman Project components.
Performance is acceptable, I've never run any of the other compressors, but it takes around 30 seconds to do the ~170 Javascript files in Roo javascript library.
One key change that's been done is the use of a token tree which makes scope detection considerably simpler.
Recent changes include flagging IE trailing comma detection
