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:

While the safe navigation operator is generally a good idea, when checking foo&.blank? in a conditional, foo being nil will actually do the opposite of what the author intends:

foo&.blank? #=> nil foo.blank? #=> true

Checks to make sure safe navigation isn't used with blank? in a conditional.

Example

# bad do_something if foo&.blank? do_something unless foo&.blank? # good do_something if foo.blank? do_something unless foo.blank?
