Extract method

The Extract Method refactoring allows you to extract a specified code fragment into its own method.

To extract a method:

Select a code fragment to refactor or place the caret at a string containing the required code fragment:
In the main menu, go to Refactor | Extract/Introduce | Method Ctrl+Alt+M.
In the Extract Method dialog, specify the method visibility, name and, optionally, parameter names:
Click OK to finish refactoring:

Example

                    class Hello
                        def greet
                            name = "JetBrains"
                            puts "Hello from #{name}"
                        end
                    end
                

                    class Hello
                        def greet
                            name = "JetBrains"
                            puts get_greeting(name)
                        end

                        private

                        def get_greeting(name)
                            "Hello from #{name}"
                        end
                    end
