Hi everyone,
My name is Angus and I'm applying for GSOC 2013 under Sympy. Normally I
maintain and develop Mathics http://mathics.org/ (another CAS which uses
Sympy extensively). I hope to work on the assumptions module and fix as
many assumption related issues as possible. Here's a link to my
Hi,
More work on the assumption module is certainly needed and welcomed.
You should learn about the differences between the old and the new
assumption modules and study the other GSoC proposals about
assumptions (they are public on our github wiki). It would also be
useful for you if you look at
Sorry for spamming here but a review on this would be helpful.

I had a look at the other proposals and realized someone else is apply for
the assumptions project and they seem to be much better prepared than I am,
so I've decided to change projects. My new project is something I have more
experience in:
Something that is on my wish list that is related to parsing is to commit,
with every PR a snapshot of the coverage of the code base as generated with
the coverage tool that we use. Then, when the new tests are run a new
version is generated and a comparison is made to see that no line that was
That's an interesting idea, and I think it definitely has merit. I
recently ran into a similar issue where adding an exact value meant that
some other simplifying code was skipped.
We'd probably have to store this 'snapshot of the coverage' on a server
somewhere/
We could use the diff
I was thinking the snapshot could just be stored in the docs folder (or
similar).

The ast module is similar, and we could certainly reuse that for the
symbolic representation of python (in fact it's already been started
somewhat). The limitation of ast is that it only supports python.
