exists [version] [ci]

Like ActiveSupport's presence, but for Object#null?

For example, this is useful when setting defaults via or: object.exists || other_object

Setup

Add to your Gemfile:

gem 'exists'

Usage

class NullObject
  def null?
    true
  end
end

nil.exists #=> nil
NullObject.new.exists #=> nil
"some object".exists #=> "some object"
