# 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 https://blog.sonarsource.com/cognitive-complexity-because-testability-understandability/

## Rules

- [CognitiveComplexity::ProhibitExcessCognitiveComplexity](https://metacpan.org/pod/Perl::Critic::Policy::CognitiveComplexity::ProhibitExcessCognitiveComplexity) - Avoid code that is nested, and thus difficult to grasp.

## 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
