Use %i
or %I
for an array of symbols. Open

- Exclude checks
This cop can check for array literals made up of symbols that are not using the %i() syntax.
Alternatively, it checks for symbol arrays using the %i() syntax on projects which do not want to use that syntax.
Configuration option: MinSize
If set, arrays with fewer elements than this value will not trigger the
cop. For example, a MinSize
of 3
will not enforce a style on an
array of 2 or fewer elements.
Example: EnforcedStyle: percent (default)
# good
%i[foo bar baz]
# bad
[:foo, :bar, :baz]
Example: EnforcedStyle: brackets
# good
[:foo, :bar, :baz]
# bad
%i[foo bar baz]
Missing top-level documentation comment for class ApplicationController
. Open
class ApplicationController < ActionController::Base
- Read upRead up
- Exclude checks
This cop checks for missing top-level documentation of classes and modules. Classes with no body are exempt from the check and so are namespace modules - modules that have nothing in their bodies except classes, other modules, constant definitions or constant visibility declarations.
The documentation requirement is annulled if the class or module has a "#:nodoc:" comment next to it. Likewise, "#:nodoc: all" does the same for all its children.
Example:
# bad
class Person
# ...
end
module Math
end
# good
# Description/Explanation of Person class
class Person
# ...
end
# allowed
# Class without body
class Person
end
# Namespace - A namespace can be a class or a module
# Containing a class
module Namespace
# Description/Explanation of Person class
class Person
# ...
end
end
# Containing constant visibility declaration
module Namespace
class Private
end
private_constant :Private
end
# Containing constant definition
module Namespace
Public = Class.new
end
# Macro calls
module Namespace
extend Foo
end
Example: AllowedConstants: ['ClassMethods']
# good
module A
module ClassMethods
# ...
end
end
