module RuboCop
module Cop
module Naming
# This cop checks for class and module names with
# an underscore in them.
#
# `AllowedNames` config takes an array of permitted names.
# Its default value is `['module_parent']`.
# These names can be full class/module names or part of the name.
# eg. Adding `my_class` to the `AllowedNames` config will allow names like
# `my_class`, `my_class::User`, `App::my_class`, `App::my_class::User`, etc.
#
# @example
# # bad
# class My_Class
# end
# module My_Module
# end
#
# # good
# class MyClass
# end
# module MyModule
# end
# class module_parent::MyModule
# end

MSG = 'Use CamelCase for classes and modules.'
