Gem::UserInteraction

UserInteraction allows RubyGems to interact with the user through standard methods that can be replaced with more-specific UI methods for different displays.

Since UserInteraction dispatches to a concrete UI class you may need to reference other classes for specific behavior such as Gem::ConsoleUI or Gem::SilentUI.

Example:

class X
  include Gem::UserInteraction

  def get_answer
    n = ask("What is the meaning of life?")
  end
end
