Hey there. This week was pretty interesting and rich for new stuff. I’ve started investigating Ruby and it’s object model and found quite an interesting repo on metaprogramming and ruby object model itself. You can take a look on it. But that wasn’t something i wanted to talk about. I was glad to find, how to create a method that could be used without creating an instance of class itself (class methods).
module Foo class Bar def bar_instance_method puts 'bar_instance_method worked' end def self.bar_class_method puts 'bar_class_method worked' end class << self def bar_class_method_other_way puts 'bar_class_method_other_way worked' end end end end puts Foo::Bar.new.bar_instance_method puts Foo::Bar.bar_class_method puts Foo::Bar.bar_class_method_other_way
bar = Foo::Bar.new
class << bar
def new_bar_instance_method
puts 'new_bar_class_method'
end
end
bar.new_bar_instance_method
class Foo::Bar
def new_bar_inherited_instance_method
puts 'new_bar_inherited_instance_method'
end
end
bar.new_bar_inherited_instance_method
