Defined in:

Overview

This cop checks the style of children definitions at classes and modules. Basically there are two different styles:

The compact style is only forced for classes/modules with one child.

Examples:

EnforcedStyle: nested (default)

# good
# have each child on its own line
class Foo
  class Bar
  end
end

EnforcedStyle: compact

# good
# combine definitions as much as possible
class Foo::Bar
end
