ruby: mass initializing instance variables

Question

Is there an easy way to bulk assign instance variables

  def initialize(title: nil, label_left: nil, label_right: nil, color_set: nil)
    @title = title
            


        

Answer 1

@tadman provided already an excellent answer to this, but here is one more: If you are willing to dispense with named parameters, you could do it like this:

def initialize(*args)
  @title, @label_left, @label_right, @color_set, *nada = args
  fail "Too many arguments" unless nada.empty?
end 

[UPDATE: Fixed the code, according to the comment given by @sawa].
