How to share variables across my .rb files?

Question

I have a few .rb files and I want to use the same variables in all of them. Let\'s say variable test_variable = \"test\" should be accessible from

Answer 1

module Foo
  attr_accessor :test_var
  def initialize
    @test_var = "hello world"
  end
end

Create the module with your variable or variables in your config file and then include the module in whatever class you intend to use.

require_relative 'foomod.rb'
class Bar
  include Foo
end

foobar = Bar.new
foobar.test_var = "goodbye"
puts foobar.test_var

Each instance of the class will initialize with whatever value you would like.
