Extract module

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

To extract a module:

  1. Place a caret at a class name or any place within a class.

  2. Select Refactor | Extract/Introduce | Module from the main menu.

  3. 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
