jones-complexity

Flake8 extension to calculate per-line complexity and total code density.

Installation

$ pip install jones-complexity

Usage (Standalone)

$ python -m jones_complexity --min 5 your_file.py

Usage (flake8)

$ flake8 --max-line-complexity 15 --max-jones-score 8 yourproject

What is this?

Because

if user.get_full_name().toUpper().split(' ')[0] == 'ALICE':
    return True

is harder to read and maintain than

if first_name == 'Alice':
   return True

Shamelessly named after myself, in the tradition of McCabe and Halstead.
