    Cognitive Complexity

    Cognitive Complexity is a measure of how difficult a unit of code is to intuitively understand. Unlike Cyclomatic Complexity, which determines how difficult your code will be to test, Cognitive Complexity tells you how difficult your code will be to read and comprehend.

    A method's cognitive complexity is based on a few simple rules:

    • Code is not considered more complex when it uses shorthand that the language provides for collapsing multiple statements into one
    • Code is considered more complex for each "break in the linear flow of the code"
    • Code is considered more complex when "flow breaking structures are nested"

    Method initialize has a Cognitive Complexity of 18 (exceeds 5 allowed). Consider refactoring.
    Open

      def initialize(signo = nil, signm = nil)
    # MRI overrides this behavior just for SignalException itself
    # but not for anything that inherits from it, therefore we
    # need this ugly check to make sure it works as intented.
    return super(signo) unless self.class == SignalException
