A Script Calls Action

Photoshop
,
1

I have hundreds pano photos. They have two files to merge. I use Photomerge which works very well. It is very annoy for me to execute Photomerge manually. I read about plugin and script. I created a simple pluging with Javascript. I managed to open a folder to open two photos to merge. I realized that Action will not record Photomerge, so I created my own action to merge them. I used Align and Blend functions. The script opens two files and call the action. It creates problems.

First thing, the action works perfect when I put two files in Photoshop and run the action every time. When the script calls the action, it will stuck at an alert message “The command ‘Auto-Blend Layers’ is not currently available.” I wrote a pause between Align and Blend and noticed that Photoshop’s document will not perform final align layers before call blend. It tried to select both layers but the document is still in single layer. I believe the action performs too quick. So, I change Playback Options: Accelerated to Step by Step or Pause for 2 seconds. Few times, it works but most time Photoshop crashes.

I got this message from Photoshop log. First two command messages which are my script wrote message. Last two command messages from Photoshop which it doesn’t helpful.

My code is here:

async function targetFunction() {
    const fs = require('uxp').storage.localFileSystem;
     
    var folder = await fs.getFolder();
    var entries = await folder.getEntries();  
    
    for (const entry of entries) {

        if (entry.isFile) {
            const content = await entry.read({ encoding: 'utf-8' });
            console.log(entry.name);
            await require('photoshop').app.open(entry);
        }        
    }
        
    var name = "Custom";
    var action = "Manual Pano 08";

    playAction(name, action);
}

async function playAction(setName, actionName) {
//function playAction(setName, actionName) {

    let setFound = false;
    let actionFound = false;

    const actionSets = require('photoshop').app.actionTree;

    // check for action set name to exist    
    for (let i = 0; i < actionSets.length; i++) {
        if (actionSets[i].name == setName) { var setToPlay = actionSets[i]; setFound = true; }
    }

    //check for action name to exist    
    if (setFound == true) {
        for (let i = 0; i < setToPlay.actions.length; i++) {
            if (setToPlay.actions[i].name == actionName) {
                var actionToPlay = setToPlay.actions[i];
                actionFound = true;
            }
        }
    }

    //play if action set/action both exist    
    if (setFound == true && actionFound == true) { await actionToPlay.play(); }
}

I believe you need to run it in a modal state

Ohhh, I think you are right. I will work on it this week and report end of the weekend. I hope. And Thank you so much.

Thank you Karmalakas. The link led me to resolve. When I read the guide, they said Photoshop changed how runs synchronous to asynchronous. I was wondering how can I manage it.

Resolved here:

playAction(name, action);

Changed to this. It will go in another nested model state.

try {
    await require('photoshop').core.executeAsModal(() => playAction(name, action), { commandName: "Merging" });
}
catch (e) {
    console.log(e);
}
