Complexity

Written by Loren Segal in 2009

SYNOPSIS

Calculates the McCabe cyclomatic complexity index of the methods in your Ruby code. The calculation is a basic NUMBER_OF_BRANCHES + 1 calculation which can be used this calculation to approximate the minimum number of test cases for each of your methods (complexity should equal number of test cases). You can also use this value to find overly complex method and refactor them into simpler ones.

USAGE

Syntax: ruby complexity.rb [--csv] GLOB_OF_FILES

If you want CSV output, add --csv. GLOB_OF_FILES defaults to lib/**/*.rb.
