class Test
def hello
puts "hello"
end
end

Test.hello

How would I get this to work? I get undefined method ‘hello’ for
Test:Class

Try this:

 class Test
   def Test.hello
     puts "hello"
   end
 end

Hope this helps,

thanks everyone.
def Test.hello was the answer for everyone else who might wonder.

I’ve noticed that self.hello works just as well. Are there any
disadvantages to this?

Smells like python, but it isn’t a disadvantage (at least) for me ;>

See http://www.rubygarden.org/ruby?ClassMethods for more on this
matter. There’s no “disadvantage” as such, but it’s good for you to
know the various ways of defining class methods.
