Extract module

The Extract Module refactoring allows you to extract certain members from a selected class into a separate module.

To extract a module:

Place a caret at a class name or any place within a class.
Select Refactor | Extract/Introduce | Module from the main menu.
In the Extract Module dialog, specify the module name, a directory where it should be placed, and select members to be added:
Click OK. RubyMine will create a module in a separate file.

Example

                    # 'cat.rb' file
                    class Cat
                        def breathe
                            puts "inhale and exhale"
                        end
                        def speak
                            puts "Meow"
                        end
                    end
                

                    # 'cat.rb' file
                    class Cat
                        include Animal

                        def speak
                            puts "Meow"
                        end
                    end

                    #
                    # 'animal.rb' file
                    module Animal
                        def breathe
                            puts "inhale and exhale"
                        end
                    end
