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
