Re: [Cython] [GSoC] Python backend for Cython using PyPy's FFI

Hi again PyPy has functions to parse C headers to get macros and constants so I could create C functions to wrap the macros and probably inline constants in the Python part of the wrapper. This doesn't solve the problem of ifdefs but this is a start. Cheers Romain 2011/4/7 Carl Witty >

[Cython] [GSoC] Python backend for Cython using PyPy's FFI

people to port their Cython code to PyPy. For the moment I've been mostly in touch with the PyPy people and they seem happy with my proposal. Of course I'm available for questions. Cheers Romain ___ cython-devel mailing list cython-d

Re: [Cython] [GSoC] Python backend for Cython using PyPy's FFI

t can be rather inefficient though since we need to do an if/else to compare the value we want to set with every C globals). Do you think I'm on the right way ? Thanks Romain ___ cython-devel mailing list cython-devel@python.org http://mail.python.

Re: [Cython] Scope resolution in a Visitor

ot;external" declarations? I > guess so, even if they may be shared between modules. There's 2 possibilities I think : - For each file we generate the wrapping functions - For each pxd file, generate a file containing the wrapping functions Romain

Re: [Cython] Transformation of pxds

Cython/Compiler/ExprNodes.py Is this useful (since I don't think it has anything to do with expression analysis) and do you have an idea on how I can solve this (my first idea is : extend the class to disable the effect of this method but it's more a hack than anything else) ? Che

[Cython] Cython bug ?

Hi I tried to compiled Demos/primes.pyx using the ctypes backend and I think I've found a bug : The Entry for the kmax parameter does not set is_arg to 1. However if I turn the def into a cdef, it works fine. Is this a bug or a known hack ? Thanks R

Re: [Cython] Cython-ctypes branch

ding modules is not trivial, the entire program must be type-inferable (which probably isn't the case of most Cython programs), global variables are considered constants, and I think (don't quote me) that the JIT doesn't work on rpython code. I have no idea on the speedup/s
