Method expand has a Cognitive Complexity of 6 (exceeds 5 allowed). Consider refactoring.

    def expand(behavior = nil, values = {})
      return to_s if values.empty? or behavior == :ignore
      raise ExpandError,    "cannot expand with keys %p" % values.keys.sort if behavior == :raise
      raise ArgumentError,  "unknown behavior %p"        % behavior         if behavior != :append
      params    = values.map { |key, value| @@uri.escape(key.to_s) + "=" + @@uri.escape(value.to_s, /[^\w]/) }

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"
