How do I create a ruby Hello world?

Question

I know in PHP you have to intrepret a page like index.php, but in Ruby how does it work? I don't know what is the Ruby extension like index.php for PHP. Could you help me?

Answer 1

If you are talking about a command line program this will work.

puts "Hello World" 

or if you want an object oriented version

class HelloWorld    def initialize(name)       @name = name.capitalize    end    def sayHi       puts "Hello #{@name}!"    end end  hello = HelloWorld.new("World") hello.sayHi 

If you are looking for a ruby on rails version of Hello World. Check the Getting Started Guide for Rails.
