How can I exit quietly from Elixir?

Question

Process.exit(self, :normal) does the job, but it prints out ** (EXIT from #PID<0.49.0>) normal. Is there a way to exit without the message?

Answer 1

It depends on which application you are running. If you are building a script, you can invoke System.halt(0). If you have an application, do not call System.halt(0), as it will shutdown the whole system without considering all other applications. Instead use System.stop(0).

Alternatively, you can call exit(:shutdown) to exit the current process. :shutdown is a common reason for exit in OTP and if you are inside .exs files, it will work just fine too.
