How to strip source from distutils binary distributions?

I want to create a bytecode-only distribution from distutils (no really, I do; I know what I'm doing). Using setuptools and the bdist_egg command, you can simply provide the --exclude-source parameter. Unfortunately the standard commands don't have such an option.

"the standard commands don't have such an option"?

Do you have the latest version of setuptools installed? And did you write a setup.py file?

If so, this should work: python setup.py bdist_egg --exclude-source-files.

Maybe a full working code here :)

try:
        from setuptools.command.build_py import build_py
except ImportError:
        from distutils.command.build_py import build_py

import os
import py_compile

class custom_build_pyc(build_py):
    def byte_compile(self, files):
        for file in files:
            if file.endswith('.py'):
                py_compile.compile(file)
                os.unlink(file)
....
setup(
    name= 'sample project',
    cmdclass = dict(build_py=custom_build_pyc),
....

Try this:

from distutils.command.install_lib import install_lib

class install_lib(install_lib, object):

    """ Class to overload install_lib so we remove .py files from the resulting
    RPM """

    def run(self):

        """ Overload the run method and remove all .py files after compilation
        """

        super(install_lib, self).run()
        for filename in self.install():
            if filename.endswith('.py'):
                os.unlink(filename)

    def get_outputs(self):

        """ Overload the get_outputs method and remove any .py entries in the
        file list """

        filenames = super(install_lib, self).get_outputs()
        return [filename for filename in filenames
                if not filename.endswith('.py')]

The distutils "build_py" command is the one that matters, as it's (indirectly) reused by all the commands that create distributions. If you override the byte_compile(files) method, something like:

try:
    from setuptools.command.build_py import build_py
except ImportError:
    from distutils.command.build_py import build_py

class build_py(build_py)
   def byte_compile(self, files):
       super(build_py, self).byte_compile(files)
       for file in files:
           if file.endswith('.py'):
               os.unlink(file)

setup(
    ...
    cmdclass = dict(build_py=build_py),
    ...
)

You should be able to make it so that the source files are deleted from the build tree before they're copied to the "install" directory (which is a temporary directory when bdist commands invoke them).

Note: I have not tested this code; YMMV.
