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 a caret at a string containing the required code fragment:
From the main menu, select Refactor | Extract/Introduce | Method Control+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
