flint-mccabe 0.1

McCabe checker, plugin for flint

Ned’s script to check McCabe complexity.

This module provides a plugin for flint, the Python code checker.

Installation

You can install, upgrade, uninstall flint-mccabe with these commands:

$ pip install flint-mccabe
$ pip install --upgrade flint-mccabe
$ pip uninstall flint-mccabe

Plugin for Flint

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: 0.1)

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.
