NAME

Perl::Critic::CognitiveComplexity - Cognitive Complexity, Because Testability != Understandability

DESCRIPTION

Perl::Critic::Policy::CognitiveComplexity::ProhibitExcessCognitiveComplexity is a rule that checks the cognitive complexity score of your subroutines. It is based on a new scoring algorithm introduced by SonarSource. See SonarSource blog entry.

Rules

CognitiveComplexity::ProhibitExcessCognitiveComplexity - Avoid code that is nested, and thus difficult to grasp. Examples can be seen in the Policy POD.

Configuration

The default complexity score before code starts to be reported with medium severity, is 10. This can be changed by changing the warn_level parameter. By default all subroutines with complexity level of more than 0 are reported in lowest severity level. This allows third-party tools to pick up these values as code metrics.

  [Perl::Critic::Policy::CognitiveComplexity::ProhibitExcessCognitiveComplexity]
  warn_level = 10
  info_level = 1
