Is there a way to instantly revert any script to its original state?

Hi @dublove, yes in most cases it is possible. Just make sure you call your script using app.doScript and pass it UndoModes.ENTIRE_SCRIPT.

For example, this is my code on a question you posted previously:

function main() {

    var doc = app.activeDocument;
    var items = doc.selection;

    // must update `items` with new item references
    items = setItemStackingOrder(doc, items, sortByLeftTop);

    // just for testing final order, print the names
    for (var i = 0; i < items.length; i++) {
        $.writeln(i + ': item ' + items[i].name);
    }

};
app.doScript(main, ScriptLanguage.JAVASCRIPT, undefined, UndoModes.ENTIRE_SCRIPT, 'Set Stacking Order');

In fact, you you will see this on every script I have ever posted for you lol 🙂

EDIT (for extra info): What we are doing is calling the `main` function using the app.doScript call. So any code you put in the `main` function will execute, even if it just calls another function. You don't have to use `main`—name it whatever you want. You can still use other functions as normal, so long as they are in scope (visible to the `main` function, for example).
