Overview

This class is part of a private API. This class may only be used in the Homebrew/brew repository. Third parties should avoid using this class if possible, as it may be removed or changed without warning.

Note:

Auto-correction for this cop is unsafe because ' '.empty? returns false, but ' '.blank? returns true. Therefore, auto-correction is not compatible if the receiver is a non-empty blank string.

Checks for code that can be simplified using Object#blank?.

Example

# bad
foo.nil? || foo.empty?
foo == nil || foo.empty?

# good
foo.blank?
