gem 'arukamo'

And then execute:

$ bundle

Or install it yourself as:

$ gem install arukamo

Because the parent class of all classes, BasicObject, is an explicit blank class, each of its instances SHOULD be considered as a null object.

Also, an object exists if all of the following methods MAY return false:

• nil?
• blank?
• empty?
• equal?(false)
• public_methods(false).empty?
• zero?

When an object exists, the #aru? method returns true. Otherwise, false. #nai? is the opposite.

BasicObject.new.aru?  # => false
nil.nai?              # => true
''.aru?               # => false
42.aru?               # => true
0.0.aru?              # => false
[].aru?               # => false
{}.aru?               # => false
