Hi Stefan, yes, I'm working on this, in fact I'm trying to recompile json module (http://docs.python.org/library/json.html) adding some type definitions and cython things o get the code faster.
I'm getting in trouble with some things too, I'm going to enumerate here so that, you could give me some tips about how to solve them. 1 - Compile package modules - json module is inside a package (files: __init__.py, decoder.py, encoder.py, decoder.py) is there a way to generate the cython modules just like its get generated by cython? 2 - Because I'm getting in trouble with issue #1, I'm running the tests manually, I go to %Python-dir%/Lib/tests/json_tests, get the files corresponding to the tests python make and run manually. 3 - To get the performance of the module, I'm thinking about to use the timeit function in the unit tests for the project. I think a good number of executions would be made and it would be possible to compare each time. 4 - I didn't create the .pxd files, some problems are happening, it tells methods are not defined, but, they are defined, I will try to investigate this better The code is in this repository: https://github.com/arthursribeiro/JSON-module your feedback would be very important, so that I could improve my skills to get more and more able to work sooner in the project. I think some things implemented in this rewriting process are going to be useful when doing this with C modules... Thank you very much. Best Regards.
