I have some high level questions about CSymPy. - What are the goals of the project?
- What are the things that should definitely go in CSymPy? - What are the things that should definitely not go in CSymPy? - How will CSymPy be architectured to allow things to happen in CSymPy when they can but fallback to SymPy when they cannot. My main concern here is that CSymPy has not clear separation from SymPy, and as a result it will end up growing larger and larger, until it becomes an independent CAS (which is fine if that's the goal, but my understanding was that it was supposed to be just a small fast core). In particular, if there is some feature of SymPy functions, how will CSymPy be architectured so that it can take advantage of it without having to completely reimplement that function in C++? For instance, a current goal of CSymPy is to implement trig functions. But this can be quite complicated if you consider all the different things you can do with trig functions. Without even thinking about trig simplification, there are complicated evaluation issues (e.g., consider sin(pi/7).rewrite(sqrt) in SymPy). It would be a shame to reimplement all this logic twice, especially it is not needed for performance. Finally, I noticed that the CSymPy Python API doesn't adhere to SymPy standards, e.g., it doesn't use .args. I think a first step in this direction would be to make all CSymPy objects completely compatible with SymPy. Probably a good idea would be to mixin Basic to all CSymPy classes (is this possible?).
