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
