Overview

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.

Examples:

# bad
class My_Class
end
module My_Module
end

# good
class MyClass
end
module MyModule
end
class module_parent::MyModule
end

Configuration Helpers.

#cop_name, #excluded_file?,
#external_dependency_checksum

This method should be overridden when a cop’s behavior depends on state that lives outside of these locations:

#inspect
#message

Gets called if no message is specified when calling add_offense or add_global_offense Cops are discouraged to override this; instead pass your message directly.

#name

Alias for Base#cop_name.

#offenses,
#on_investigation_end

Called after all on_…​

#on_new_investigation

Called before all on_…​
