Pattern: Redundant :: prefix on constant

Issue: -

Description

Avoid redundant :: prefix on constant.

How Ruby searches constant is a bit complicated, and it can often be difficult to understand from the code whether the :: is intended or not. Where Module.nesting is empty, there is no need to prepend ::, so it would be nice to consistently avoid such meaningless :: prefix to avoid confusion.

NOTE: This rule is disabled if Lint/ConstantResolution rule is enabled to prevent conflicting rules. Because it respects user configurations that want to enable Lint/ConstantResolution rule which is disabled by default.

Examples

# bad
::Const

# good
Const

# bad
class << self
  ::Const
end

# good
class << self
  Const
end

# good
class A
  ::Const
end

# good
module A
  ::Const
end
