code checking using pep8 and pyflakes
Flake8 is a wrapper around these tools:
- Ned’s MacCabe script
Flake8 runs all tools by launching the single ‘flake8’ script, but ignores pep8 and PyFlakes extended options and just uses defaults. It displays the warnings in a per-file, merged output.
It also adds a few features:
files that starts with this header are skipped:
# flake8: noqa
lines that contains a “# NOQA” comment at the end will not issue a warning
a Mercurial hook

To use the Mercurial hook on any commit or qrefresh, change your .hg/rc file like this:
[hooks] commit = python:flake8.hg_hook qrefresh = python:flake8.hg_hook [flake8] strict = 0
If strict option is set to 1, any warning will block the commit. When strict is set to 0, warnings are just displayed in the standard output.
