Pattern: Wrong mixin grouping

Issue: -

Description

This rule checks for grouping of mixins in class and module bodies. By default it enforces mixins to be placed in separate declarations, but it can be configured to enforce grouping them in one declaration.

Examples

EnforcedStyle: separated (default)

# bad
class Foo
  include Bar, Qox
end

# good
class Foo
  include Qox
  include Bar
end

EnforcedStyle: grouped

# bad
class Foo
  extend Bar
  extend Qox
end

# good
class Foo
  extend Qox, Bar
end

Default configuration

Attribute	Value
EnforcedStyle	separated
SupportedStyles	separated, grouped
