Running ruby code

Question

I am working on a remote server with Putty. My class looks like:

class Hangman
  def initialize
    puts "Hello world"
  end
end

But when I write in Putty ruby hangman.rb, it skips to the next editor console line without showing anything. Any suggestions?

You need to actually do something; you're just defining a class. — Dave Newton

Add Hangman.new at the end to see your message. Or in irb type load "hangman.rb" then you can try out your new class interactively — Neil Slater

class Hangman
  def initialize
    puts "Hello world"
   end
end

hangman = Hangman.new

So you forgot to crate an instance of the object you defined. Everytime you call .new method on your object, you get a new instance of it and code inside def initialize is ran.

added, but still nothing. My file is called hangman.rb and the class is called Hangman. Ideas?

You define the class (with the constructor) but you don't use it. Create an object:

Hangman.new
