How do I use define_method to create class methods?

Question

This is useful if you are trying to create class methods metaprogramatically:

def self.create_methods(method_name)
    # To create instance methods:
    defi         


        

Answer 1

I think in Ruby 1.9 you can do this:

class A
  define_singleton_method :loudly do |message|
    puts message.upcase
  end
end

A.loudly "my message"

# >> MY MESSAGE
