Dear All, I've finally gotten around to posting the code for my cython wrapper for the computer algebra package LiE:
http://github.com/davidsd/lie Basically, the project contains a copy of the LiE source, some extra C files, and a cython file (lie.pyx) that references functions from LiE and defines extension classes and some more abstract python objects. It currently works well enough for what I made it for (http://arxiv.org/abs/0910.4585). However, there are many ways it could be improved. Since I'm no longer striving towards a specific goal, and I have other projects to work on, it's hard for me to prioritize one improvement over another. So I'd be grateful if those who are interested could take a look, let me know what improvements/features they think are important, and perhaps help me work towards them.
