Using Ruby to Craft and Test Beautiful Command Line Applications
summary
Ruby is used to build and test CLI apps that honor piping, signals and tty detection, parse options with OptionParser or Thor, and reuse config via .rb files; prefer mixlib-shellout or popen3 for subprocess streams, make confirmations scriptable and reversible where possible, expose plugin hooks, log with -v/--quiet flags, and run integration tests by running tests in disposable containers rather than brittle mocks so commands actually change filesystem, network or process state and can be validated end-to-end.
