Wait for Pro Tools to Open Session

This line of code:

while (!sf.ui.proTools.invalidate().hasValidUI) {
            sf.wait({ intervalMs: 200 })
        }

is saying "AS long asPT doesn't have a valid UI (User Interface - ie. an open window and valid menubar), wait 200 ms and check again.

So your Finder action is triggered as soon as a PT window of any sort appears onscreen.

What you need to do is put this after the code above and before your Finder action:

sf.ui.proTools.waitForNoModals();

This will wait for all loading and activity windows to close before proceeding.
Depending on how long it takes for PT to open a session the you may have to repeat it a couple of times

Hey @Ryan_DeRemer!

Glad @Chris_Shaw was able to explain the "valid UI" bit - that part tripped me up when I was getting started.

Here's an extended function that will open a Pro Tools session and dismiss all dialogs, which is my typical use case:

// Function - Dismiss Missing Files Dialog
    /**
     * @param {Object} obj
     * @param {"Skip All"|"Manually Find & Relink"|"Automatically Find & Relink"} obj.radioButton}
     */
    function dismissMissingFilesDialog({ radioButton }) {
        const dlg = sf.ui.proTools.windows.whoseTitle.is("Missing Files").first;

        //Wait for dialog box to appear
        dlg.elementWaitFor({
            timeout: 300,
            pollingInterval: 10,
            onError: "Continue",
        });

        if (dlg.exists) {
            dlg.radioButtons.whoseTitle.is(radioButton).first.elementClick();
            dlg.buttons.whoseTitle.is("Ok").first.elementClick();

            dlg.elementWaitFor({
                waitType: "Disappear",
                timeout: 100,
                pollingInterval: 10,
                onError: "Continue",
            });
        }
    }

function waitForSessionToOpen() {
        try {
            while (!sf.ui.proTools.invalidate().hasValidUI) {
                sf.wait({ intervalMs: 200 });
            }
            while (sf.ui.proTools.invalidate().windows.filter(w => w.title.value.match(/^(Edit:|Mix:)/)).length.valueOf() === 0) {
                // Ignore Missing I/O
                if (sf.ui.proTools.windows.whoseTitle.is("Session Notes").first.exists) {
                    sf.ui.proTools.windows.whoseTitle.is("Session Notes").first.buttons.whoseTitle.is("No").first.elementClick();
                    sf.ui.proTools.windows.whoseTitle.is("Session Notes").first.buttons.whoseTitle.is("No").first.elementWaitFor({ waitType: "Disappear" });
                }

                // Ignore Missing Plug-ins
                if (sf.ui.proTools.windows.whoseTitle.is("Missing AAX Plug-ins").first.exists) {
                    sf.ui.proTools.windows.whoseTitle.is("Missing AAX Plug-ins").first.buttons.whoseTitle.is("No").first.elementClick();
                    sf.ui.proTools.windows.whoseTitle.is("Missing AAX Plug-ins").first.buttons.whoseTitle.is("No").first.elementWaitFor({ waitType: "Disappear" });
                }

                // Dismiss missing files..."" dialog if it appears
                dismissMissingFilesDialog({
                    radioButton: "Skip All",
                });

                // Dismiss generic alert
                if (sf.ui.proTools.windows.whoseDescription.is("alert").first.exists) {
                    sf.ui.proTools.windows.whoseDescription.is("alert").first.getElement("AXDefaultButton").elementClick();
                    sf.ui.proTools.windows.whoseDescription.is("alert").first.getElement("AXDefaultButton").elementWaitFor({ waitType: "Disappear" });
                }
                sf.wait({ intervalMs: 200 });
            }
        }
        catch (ex) {
            sf.wait({ intervalMs: 500 });
            while (sf.ui.proTools.invalidate().windows.filter(w => w.title.value.match(/^(Edit:|Mix:)/)).length.valueOf() === null) {
                // Ignore Missing I/O
                if (sf.ui.proTools.windows.whoseTitle.is("Session Notes").first.exists) {
                    sf.ui.proTools.windows.whoseTitle.is("Session Notes").first.buttons.whoseTitle.is("No").first.elementClick();
                    sf.ui.proTools.windows.whoseTitle.is("Session Notes").first.buttons.whoseTitle.is("No").first.elementWaitFor({ waitType: "Disappear" });
                }

                // Ignore Missing Plug-ins
                if (sf.ui.proTools.windows.whoseTitle.is("Missing AAX Plug-ins").first.exists) {
                    sf.ui.proTools.windows.whoseTitle.is("Missing AAX Plug-ins").first.buttons.whoseTitle.is("No").first.elementClick();
                    sf.ui.proTools.windows.whoseTitle.is("Missing AAX Plug-ins").first.buttons.whoseTitle.is("No").first.elementWaitFor({ waitType: "Disappear" });
                }

                // Dismiss missing files..."" dialog if it appears
                dismissMissingFilesDialog({
                    radioButton: "Skip All",
                });

                // Dismiss generic alert
                if (sf.ui.proTools.windows.whoseDescription.is("alert").first.exists) {
                    sf.ui.proTools.windows.whoseDescription.is("alert").first.getElement("AXDefaultButton").elementClick();
                    sf.ui.proTools.windows.whoseDescription.is("alert").first.getElement("AXDefaultButton").elementWaitFor({ waitType: "Disappear" });
                }
                sf.wait({ intervalMs: 200 });
            }
        }
    }

It's a bit hacky using the "try" / "catch," but there seems to be one moment when loading that CAN trip up the while loop otherwise.

I should retry using the "menu item enabled" bit you are using now! I had tried that at one point.

Hey @Ryan_DeRemer !

Thank you for the answer! I wasn't aware of your Session Creator! It's awsome
Just to be sure, for example, if I wanted to write a script that opens the "New session" dialog that I would setup manually (without your script, simply because I deal with all sorts of sessions, so presets rarely work at that stage) then press OK and wait for the session to be open, I could just add this to the code?

function waitForPtLaunch() {
    while (!sf.ui.proTools.invalidate().hasValidUI) {
        sf.wait({ intervalMs: 200 })
    }
    for (var i = 0; i < 10; i++) {
        sf.ui.proTools.waitForNoModals();
    }
}

Sorry If my question sounds stupid. I'm deep into learning more about Javascript, and Soundflow, but it's a lot to take in. Im extremely thankful of anyone who answers my "Javascript 101" (should I say 000?) questions :D

Ahhh wow thank you brother! My first encounter with dinosaur-script hahahah. Oldie but goodie, won’t make that mistake again!
