script driven message to alert user while in emulationstation

[pinomnomnom]

Hi all,

I'm running some Adafruit fuel gauges with my portable project so I can monitor my battery life. I'd like to be able to create some kind of alert while I'm playing game so I can save, knowing that shutdown is around the corner, as a way of avoiding draining my batteries.

I'll have a conditional for the shutdown based on battery life percentage, but what I'm wondering is if there's a way to create an alert.

Side note - os.system or subprocess seems to shutdown Pi regardless of whether a conditional is met, so I have to troubleshoot this.

For RetroArch, you can enable the network control interface [1] and send a message through SHOW_MSG command, but a general solution to show an alert message would work only if you're running a desktop env (X11 or Wayland) - playing an audio sound instead would work seamlessly.

Thanks, that worked for QUIT using the example in the documentation, but where can I read more about what's needed to use SHOW_MSG?

Maybe the source or the PR that added the functionality, I can't find any other reference in the Libretro docs about it.
