Classes are open. So are modules. You can define your module in 2 files as Jesus described.

To use the module, you need to require both files.

require 'file1'
require 'file2'

Hope this helps.

Best,

In file2.rb you have to place func_b inside the module too:

 _________file2.rb_________
module MyModule
  def func_b
    ...
  end
end
