McCabe checker, plugin for flint
This module provides a plugin for flint, the Python code checker.
When both flint and flint-mccabe are installed, the plugin is available in flint:
$ flint --version 0.1 (pep8: 1.4.2, pyflakes: 0.6.1, mccabe: 0.2)
By default the plugin is disabled. Use the --max-complexity switch to enable it. It will emit a warning if the McCabe complexity of a function is higher that the value:
$ flint --max-complexity 10 coolproject ... coolproject/mod.py:1204:1: C901 'CoolFactory.prepare' is too complex (14)
This feature is quite useful to detect over-complex code. According to McCabe, anything that goes beyond 10 is too complex.
