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

Question

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?

Answer 1

• 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).
