Including Bash autocompletion with setuptools

I've got a couple packages in PyPI, and I'd like to include autocompletion features w开发者_如何学JAVAith both of them. How would you check that Bash autocompletion should be installed at all (check for /etc/bash_completion, maybe?), and how would you install it with setup.py (preferably using setuptools)?

If you're going to require OS-level packages (i.e. bash-completion), then you should distribute your library as an OS-level package. That is, in .deb, .rpm, etc. Some tips here:

• Debian New Maintainer's Guide
• Fedora Packaging Guidelines

As part of the package generation, you can call your setuptools script to install the Python code. To ensure bash-completion is installed, you can specify it is a required package.

You can use data_files options:

from setuptools import setup
setup(
  ...
  data_files=[
      ('/etc/bash_completion.d/', ['extra/some_completion_script']),
    ]
)
