Cythonize one step faster

Introduction

cythonizer.py is a script that will attempt to automatically convert one or more .py and .pyx files into the corresponding compiled .pyd | .so binary modules files. Example:

$ python cythonizer.py myext.pyx

pip install cythonizer will automatically create an executable script in your Scripts/ folder, so you should be able to simply:

$ cythonizer myext.py

or even:

$ cythonizer *.pyx

You can type:

$ cythonizer -h

to obtain the following CLI:

usage: cythonizer.py [-h] [--annotation] [--numpy-includes]
                     [--debugmode] filenames [filenames ...]

positional arguments:
filenames         .py and .pyx files only

optional arguments:
-h, --help        show this help message and exit
--annotation      (default: False)
--numpy-includes  (default: False)
--debugmode       (default: False)

• --annotation will create the HTML Cython annotation file.
• --numpy-includes will add the numpy headers to the build command.
• Compiler flags -O2 -march=native are automatically passed to the compiler.
