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

Ruby will never share local variables between files. You can wrap them in a Module though:

module SharedVaribles
  @test_var="Hello, World"

  def self.test_var
    return @test_var
  end

  def self.test_var=(val)
    @test_val=val;
  end
end

Put that in settings.rb, require it into all your files, and use SharedVaribles.test_var and SharedVaribles.test_var= to access the variable. Remember, Ruby's require is nothing like C's #include, it is much more complex. It executes the file, then imports all constants, modules, and classes to the requireer.
