個人備忘です
class Test end # define class method class << Test def hello p "hello class" end end # define instance method class Test def hello2 p "hello2 instance" end end # wanna create Class by string klass = Object.const_get("Test") klass.class_eval do define_method(:hello3) do |*values| puts "[#{values.join(",")}]" end end obj = Test.new Test.hello obj.hello2 obj.hello3("by","yah") #=> "hello class" "hello2 instance" [by,yah]
