Need Assistant with a JavaScript for Photoshop

I have a action that creates my folder structure but now I'm wanting it into a script with some logic. I want to create a main group named Workflow and nested inside are 5 groups, with the names Repair, Dodge & Burn, Selective Saturation, Color Corrections and Color Grading. Sometimes I don't use all the groups and delete them but after a revision, I tend to create the missing groups. What I'm after is if the groups exist, do nothing but if they don't, create the missing groups but in that same order.

Here's what I got so far and it creates the groups, but if some are missing, it just creates the groups on the top, not in the order when the script if first ran.

 

function createWorkflowStructure() {
    var doc = app.activeDocument;
    
    // Check if 'Workflow' group already exists
    var workflowGroup = getGroupByName(doc, "Workflow");

    if (workflowGroup == null) {
        // Create 'Workflow' group if it doesn't exist
        workflowGroup = doc.layerSets.add();
        workflowGroup.name = "Workflow";
        
        // Move 'Workflow' group to the top
        workflowGroup.move(doc, ElementPlacement.PLACEATBEGINNING);
    }

    // Define nested group names in desired order
    var nestedGroupNames = ["Repair", "Dodge & Burn", "Selective Saturation", "Color Corrections", "Color Grading"];

    // Create missing nested groups within 'Workflow' group, maintaining order
    for (var i = 0; i < nestedGroupNames.length; i++) {
        createNestedGroupIfMissing(workflowGroup, nestedGroupNames[i]);
    }
}

// Helper function to get a group by name
function getGroupByName(doc, name) {
    for (var i = 0; i < doc.layerSets.length; i++) {
        if (doc.layerSets[i].name === name) {
            return doc.layerSets[i];
        }
    }
    return null; // Group not found
}

// Helper function to create a nested group within a parent group if missing
function createNestedGroupIfMissing(parentGroup, groupName) {
    var nestedGroup = getGroupByName(parentGroup, groupName);

    if (nestedGroup == null) {
        // Create nested group if it doesn't exist
        nestedGroup = parentGroup.layerSets.add();
        nestedGroup.name = groupName;
    }
}

// Example usage:
// Call createWorkflowStructure() to ensure the structure exists
createWorkflowStructure();

I got it figured out, somewhat 😊. Thanks. 

 

That's great! I find this challenging.  :]

I'm still up if anyone wants to share their input though.

Please do share your final code, I imagine that others will find it hard to comment not knowing what you have done. Did you use ElementPlacement.PLACEBEFORE or ElementPlacement.PLACEAFTER for relative positioning inside the group?

 


Yeah but it's not fully there yet. I still need them nested inside a group called Workflow.

If I change this 

    var repairGroup = createGroupIfNeeded(doc, "Repair");

to this

    var repairGroup = createGroupIfNeeded(workFlowGroup, "Repair");

The groups are placed inside the Workflow folder but then I get extra folders outside the main 😂. Probably something simple for a fix but like I said I'm a noob

// Function to create a new group if it doesn't exist
function createGroupIfNeeded(doc, groupName) {
    try {
        // Try to get the group by name
        var group = doc.layerSets.getByName(groupName);
    } catch (e) {
        // Group doesn't exist, so create a new one
        var group = doc.layerSets.add();
        group.name = groupName;
    }
    return group;
}

// Check if Photoshop is running
if (app && app.documents.length > 0) {
    var doc = app.activeDocument;

    // Create Workflow, Repair, and Dodge & Burn groups if they don't exist
    var workFlowGroup = createGroupIfNeeded(doc, "Workflow");
    var repairGroup = createGroupIfNeeded(doc, "Repair");
    var dodgeBurnGroup = createGroupIfNeeded(doc, "Dodge & Burn");
    var selectiveSaturationGroup = createGroupIfNeeded(doc, "Selective Saturation");
    var colorCorrectionsGroup = createGroupIfNeeded(doc, "Color Corrections");
    var colorGradingGroup = createGroupIfNeeded(doc, "Color Grading");

    // Loop through existing layer sets and replace any missing ones in order
    var requiredGroups = ["Color Grading", "Color Corrections", "Selective Saturation", "Dodge & Burn", "Repair"];
    var existingGroups = doc.layerSets;

    for (var i = 0; i < requiredGroups.length; i++) {
        var requiredGroupName = requiredGroups[i];
        var existingGroup = existingGroups[i];

        if (existingGroup && existingGroup.name === requiredGroupName) {
            // Group exists and is in correct order, do nothing
        } else {
            // Group is missing or out of order, recreate it
            var newGroup = createGroupIfNeeded(doc, requiredGroupName);
            // Move the new group to the correct position
            if (existingGroup) {
                newGroup.move(existingGroup, ElementPlacement.PLACEBEFORE);
            } else {
                newGroup.move(doc.layers[doc.layers.length - 1], ElementPlacement.PLACEAFTER);
            }
        }
    }
}

@Unavowed 

 

Will the layer structure vary under the groups?

 

Will there always be a single, Background layer under the groups?

 

Will there always be a single, floating layer under the groups?

 

Will there be a variable amount of layers under the groups (either floating or Background)?

 

A conditional switch block would probably be better than multiple if blocks to check and move the layerSet into the correct position.

There will always be a Background layer, I do create what I need inside these groups, example, Dodge & Burn will have helper layers that're placed in a group itself and two curves under that, same with the Selective Saturation and Color Corrections, Color Grading mostly has any adjustment layer. 

A conditional switch? If you can make the script smaller/simplier I'm all for it 😊

I'm hoping that another scripter adds their thoughts, due to the variable layers this may be hard if using the layer id or index values.

 

Perhaps simply using getByName would be better?

 

What is your scripting skill level and knowledge?
