Hi Eugen, There is a bunch of tools like cython which are simply code generators (py -> c, a quick google search should give you a good list of them).
Imho, cython leads to ugly and unreadable python-like code and breaks the ideas and concepts behind the language. (there is a big bunch of devs behind the py core, and each design decision takes long talks and many implementations before being incorporated in the public release). Then, the c code generated by cython is unreadable and produces usually bigger binaries (example of a cython "hello world" generating hundreds lines of code where in a regular cpy extension, it could be a dozen). I also heard about lot of memory related problems. Maybe fixed now ? If you are looking for speed, I would recommend writing your modules directly in C using the C Python API which is kinda smart and convenient. (before being a language, python is a c library which is damn useful: unicode support, data-structures implementations, etc). If you don't want to bother with C, you can still use the 'ctypes' packages which will let you code in python and keeping a bridge to the C world for specific speed purposes. In a pure performances topic on processing softimage world datas, I observed: c dlls called by ctypes <= c extensions using cpython <= cython <= pure ctypes. < Im sure this scale depends of the context and the implementations. > ** prototyping ops in cython using the si python binding ? writing qt widgets in cython using pyqt ? In the way I understand it, no, it should not be possible (or maybe with a huge amount of work and time to get everything working). A python binding can be tough to produce and usually deals/answers to specific needs/cases of the target API. That's why, I would tend to prefer pybindings provided by Qt or Softimage instead of solution like this. If there is no available binding (which is kinda rare cases), or when I need speed improvements, I'm choosing, pure c/cpp implementation bind with 'ctypes' or c python extensions. Finally, I would say, in a prototyping context, there is definitively no point to use something else than pure python and official bindings, then reimplementing the code in c/cpp. Anyway, hope this general feedback will be valuable to you, jo 2012/4/17 Eugen Sares <softim...@keyvis.at> > without
