flake8 0.8

code checking using pep8 and pyflakes

Flake8 is a wrapper around these tools:

• PyFlakes

• pep8

• 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

• more things to come..

Original projects:

• pep8: http://github.com/jcrocholl/pep8/

• PyFlakes: http://divmod.org/trac/wiki/DivmodPyflakes

• McCabe: http://nedbatchelder.com/blog/200803/python_code_complexity_microtool.html

Mercurial hook

To use the Mercurial hook on any commit or qrefresh, change your .hg/rc file like this:

[hooks]
commit = python:flake8.run.hg_hook
qrefresh = python:flake8.run.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.
