Compile cython code with "python compile.py" and no "build" command-line parameter

I have a compile.py script:

from distutils.core import setup
from Cython.Build import cythonize
setup(ext_modules = cythonize("module1.pyx"))

that compiles my Cython code. The drawback is that I have to call it with a command-line parameter build:

python compile.py build

Instead, I would like to be able to call this compile.py directly from Sublime Text, as usual, with CTRL+B. To do that, it should work from:

python compile.py

Question: how to modify the above script so that it can be run with python compile.py?

  • Method #1:

    Use script_args like this:

    setup(ext_modules=cythonize("module1.pyx", build_dir="build"), script_args=['build'])

    or 

    setup(ext_modules=cythonize("module1.pyx", build_dir="build"), script_args=['build_ext'])

    (both work).

    If you want the output files to be in the same directory, you can use:

    setup(ext_modules=cythonize("module1.pyx", build_dir="build"), script_args=['build'], 
                                            options={'build':{'build_lib':'.'}})

    or

    setup(ext_modules=cythonize("module1.pyx", build_dir="build"), script_args=['build_ext'],
                                            options={'build_ext':{'inplace':True}})

  • Method #2:

    Add this on top:

     import sys; sys.argv = ["", "build"]

    It's a bit hack-ish but it works fine, and avoids to have to create a new build-system, like with Build and run with arguments in Sublime Text 2 (link kindly provided by @Melvin).
