Fizz Buzz (and possibly more) with a Chain of Responsibility

fizzbuzz.rb

class Responder
	def initialize(content, divisor, next_responder = FallbackResponder.new)
		@content, @divisor, @next_responder = content, divisor, next_responder
	end

	def respond(value, current = '')
		current << @content if value % @divisor == 0

		@next_responder.respond(value, current)
	end
end

class FallbackResponder
	def respond(value, current = '') 
		current == '' ? value : current
	end
end

# Standard FizzBuzz
buzz = Responder.new("Buzz", 5)
fizz = Responder.new("Fizz", 3, buzz)

(1..100).each do |i|
	puts fizz.respond(i)
end


# FizzBuzzBazz
bazz = Responder.new("Bazz", 7)
buzz = Responder.new("Buzz", 5, bazz)
fizz = Responder.new("Fizz", 3, buzz)

(1..100).each do |i|
	puts fizz.respond(i)
end
