When *strict* is set to **0**, warnings are just printed to the standard output. *complexity* defines the maximum McCabe complexity allowed before a warning is emitted. If you don't specify it, it's just ignored. If specified, it must be a positive value. 12 is usually a good value. Git hook -------- To use the Git hook on any *commit*, add a **pre-commit** file in the *.git/hooks* directory containing:: #!/usr/bin/env python import sys from flake8.run import git_hook COMPLEXITY = 10 STRICT = False if __name__ == '__main__': sys.exit(git_hook(complexity=COMPLEXITY, strict=STRICT, ignore='E501')) If *strict* option is set to **True**, any warning will block the commit. When *strict* is set to **False** or omitted, warnings are just printed to the standard output. *complexity* defines the maximum McCabe complexity allowed before a warning is emitted. If you don't specify it or set it to **-1**, it's just ignored. If specified, it must be a positive value. 12 is usually a good value. *lazy* when set to True will also take into account files not added to the index. Also, make sure the file is executable and adapt the shebang line so it points to your Python interpreter. 
Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
