Photoshop CC2019 自动更新所有链接的智能对象，包括嵌套的

Question

我有 Photoshop CC2019 PSD 文档，其中包含几个包含其他智能对象的智能对象。其中一些具有链接层。通常，此类图像不会自动更新（这非常烦人，Adobe！）但是一旦链接的图像内容发生变化，您必须手动更新每个图像。

有一个名为 "Update All Modified Content.jsx" 的 .jsx 脚本文件，它会自动更新链接层（在我的例子中是 PNG 图像），但前提是智能对象位于最顶层的文档中 - 即没有嵌套的智能对象带链接的图层会自动更新。

我的问题是：有谁知道如何更新上述 .jsx 文件的内容，以便它自动更新 PSD 文档中所有智能对象（包括嵌套对象）的所有链接图像？

对于那些关心或愿意帮助更新代码的人来说：

// Update all modified content
var idplacedLayerUpdateAllModified = stringIDToTypeID( "placedLayerUpdateAllModified" );
executeAction( idplacedLayerUpdateAllModified, undefined, DialogModes.NO );

所以，折腾了半天终于自己解决了。这是代码：

#target photoshop

// SET INITIAL ACTIVE DOCUMENT
var mainDocument = app.activeDocument;

// SAVE THE DOCUMENT NAME FOR FUTURE USE
var mainDocName = mainDocument.name;

// RUN THE MAIN UPDATE FUNCTION
mainDocument.suspendHistory("processAllSmartObjects", "autoupdateAllSmartObjects(mainDocument, 0)");

// FINALLY SAVE THE MAIN DOCUMENT
mainDocument.save();

function autoupdateAllSmartObjects(theParent, prevVal) {

    // FUNCTION TO TEST IF SMARTOBJECT IS LINKED
    function isLinkedSO(obj) {

        var localFilePath = "";
        var ref = new ActionReference();
        ref.putIdentifier(charIDToTypeID('Lyr '), obj.id);
        var desc = executeActionGet(ref);
        var smObj = desc.getObjectValue(stringIDToTypeID('smartObject'));  
        var isLinked = false;

        // TEST IF IT HAS LINKED FILE
        try {
            var localFilePath = smObj.getPath(stringIDToTypeID('link'));
            isLinked = true;

        } catch(e) {
            //
        }

        return isLinked; 
    }

    // FUNCTION TO UPDATE LINKED SMART OBJECT 
    function doTheUpdate(LYR, stackNr) {

        // SET ACTIVE LAYER TO ACTUALY ITERATED ONE
        app.activeDocument.activeLayer = LYR;

        // RUN IN "SILENT" MODE
        app.displayDialogs = DialogModes.NO;
        var layer = app.activeDocument.activeLayer;

        // IF ACTIVE LAYER IS SMARTOBJECT
        if (layer.kind == "LayerKind.SMARTOBJECT") {

            //alert(layer);

            // OPEN THE SMARTOBJECT
            app.runMenuItem(stringIDToTypeID('placedLayerEditContents'));

            // DO THE ACTUAL FILE UPDATE
            var idplacedLayerUpdateAllModified = stringIDToTypeID( "placedLayerUpdateAllModified" );
            executeAction( idplacedLayerUpdateAllModified, undefined, DialogModes.NO);

            // IF IT IS NOT THE "CORE/MAIN" DOCUMENT
            if(stackNr > 0) {

                // SAVE CHANGES (UPDATE) AND CLOSE IT
                app.activeDocument.close(SaveOptions.SAVECHANGES);
            }

            // CONTINUE INSIDE THIS ACTIVE SMARTOBJECT
            autoupdateAllSmartObjects(app.activeDocument, stackNr);
        }

        return;
    }

    // FUNCTION TO PARSE GROUPS
    function parseGroup(LYR) {

        var groupLayers = LYR.layers;

        // IF GROUP IS NOT EMPTY
