Working with Ruby's magical Eigenclass
I stumbled upon this nice blog article written by Philip Brown on culttt.com and had to check it out for myself.
class God def hello puts "Hello World!" end class << self # this creates "class methods" # those can be run without creating an instance first def hello puts "Let's make gods and other stuff, like a universe." end end end God.hello # => "Let's make gods and other stuff, like a universe." # vs. hello as an instance method god = God.new god.hello # => "Hello World!"
No instance of a god needed ;-)
