Per-project flake8 max line length?

Question

I'm using a Flake8 git hook in my project and I want to relax the line length limit, but only for one project. Given that it looks like there's no clear API for that, how do I modify this hook to do that? Alternatively, is there a git-config setting or an environment variable that would let me set that? Here's the hook source code:

#!/usr/bin/env python import os import sys import logging import os.path as P  from flake8.main import git   if __name__ == '__main__':     ret = git.hook(         strict=git.config_for('strict'),         lazy=git.config_for('lazy'),     )     if ret:         sys.exit(ret)

Use the setup.cfg file in each project. This file is read by various Python-related tools, including pep8 (see pep8's documentation) and flake8.

The documentation for setup.cfg with flake8 is in the Configuring Flake8 chapter. In short, you want a setup.cfg file with this content (obviously, adjust the 99 to your needs):

[flake8] max-line-length = 99 

If you don't want to create a setup.cfg file, you can also specify this as an argument to the command:

flake8 --max-line-length 99
