Overview
Tries to produce a complexity score that’s a measure of the
complexity the reader experiences when looking at a method. For that
reason it considers when
nodes as something that doesn’t add as much
complexity as an if
or a &&
. Except if it’s one of those special
case
/when
constructs where there’s no expression after case
. Then
the cop treats it as an if
/elsif
/elsif
… and lets all the when
nodes count. In contrast to the CyclomaticComplexity cop, this cop
considers else
nodes as adding complexity.
