How to trigger a command whenever Pro Tools transport is stopped

To make the code run forever, let's take the code from here:
https://forum.soundflow.org/-989#post-7

In this script I'm checking whether or not Pro Tools is playing and if we discover it stopped then it displays "Pro Tools stopped". You should insert your own code there.

You should add an Application Trigger to run this script when Pro Tools is activated.

var lastIsPlayingValue;

function main() {
    var isPlaying = sf.ui.proTools.isPlaying;
    if (isPlaying === lastIsPlayingValue) return;
    lastIsPlayingValue = isPlaying;

    if (!isPlaying) {
        //Insert your code to run here
        log('Pro Tools stopped');
    }
}

function runForever(name, action, interval, timeout) {
    var now = (new Date).valueOf();
    if (now - globalState[name] < timeout) throw 0; //Exit if we were invoked again inside the timeout

    globalState[name] = now;
    sf.engine.runInBackground(function () {
        try {
            while (true) {
                sf.engine.checkForCancellation();
                globalState[name] = (new Date).valueOf();

                action();

                sf.wait({ intervalMs: interval, executionMode: 'Background' });
            }
        } finally {
            globalState[name] = null;
        }
    });
}

runForever("isPTStoppedRunning", main, 500, 5000);
