Set system volume via script/KM variable

Questions & Suggestions

I can certainly understand Chris's preference for compiled scripts, but FWIW, from the Javascript perspective, there may be a couple of general advantages to using a shell script:

  1. KM_VAR values are easily read in the shell
  2. If you are writing reusable code (text etc) you can use a javascript module pattern to keep the KM part separate from the rest of the code, in case you want to use your .js on iOS or elsewhere.

( but 2 is probably not relevant here : - )

#!/bin/bash
osascript -l JavaScript <<JXA_END 2>/dev/null
(function (v) {
	var a = Application.currentApplication();
	a.includeStandardAdditions = true;
	a.setVolume(null, {
		outputVolume: v
	});
})($KMVAR_VOLUMESTATE);
JXA_END
