Module: ActionPolicy::PrettyPrint

Defined in:
lib/action_policy/utils/pretty_print.rb

Overview

Takes the object and a method name, and returns the “annotated” source code for the method: code is split into parts by logical operators and each part is evaluated separately.

Example:

class MyClass
  def access?
    admin? && access_feed?
  end
end

puts PrettyPrint.format_method(MyClass.new, :access?)

#=> MyClass#access?
#=> ↳ admin? #=> false
#=> AND
#=> access_feed? #=> true
