Script to remove hidden/unused Layer Effects?

[jonohunt]

Does anyone have, or know if it's possible to remove hidden/unused layer effects of selected layer(s) with a script? (Not on every layer in the document, only selected layers)

For example here I'd have to drag each unused effect to the trash can at the bottom

Would be great if you could remove the hidden ones while still leaving those that are visible via a script

Check my scripts: Magic scripts for Photoshop

I have one for layer effects and one for smart filters. But it is for all layers in document. If you want skip some layers, you can lock them.

Thanks, I saw that

But really, I'm looking for a script that runs on the selected layers.

[Jarda Bereza]

You or somebody else could change my code. But I will not do it.

[jonohunt]

Not really the kind of answer I was looking for on a 'help forum', haha.

But thanks, I might try that.

Very useful scripts, thank you, bro!

Try

var r = new ActionReference();    
r.putProperty(charIDToTypeID("Prpr"), stringIDToTypeID("targetLayers")); 
r.putEnumerated(charIDToTypeID("Dcmn"), charIDToTypeID("Ordn"), charIDToTypeID("Trgt"));
if (executeActionGet(r).hasKey(stringIDToTypeID("targetLayers")))
    {
    var list = executeActionGet(r).getList(stringIDToTypeID("targetLayers"));
    var offset = 0;
    try { activeDocument.backgroundLayer } catch (e) { offset = 1; }
    for (var n = 0; n < list.count; n++)
        {
        var idx = list.getReference(n).getIndex();
        var r = new ActionReference();    
        r.putProperty(charIDToTypeID("Prpr"), stringIDToTypeID("layerEffects")); 
        r.putIndex(charIDToTypeID("Lyr "), idx+offset);
        if (!executeActionGet(r).hasKey(stringIDToTypeID("layerEffects"))) continue;
        var d = executeActionGet(r).getObjectValue(stringIDToTypeID("layerEffects"));
        for (var i = 0; i < d.count; i++)
            {
            var key = d.getKey(i);
            var type = d.getType(key);
            if (type == DescValueType.OBJECTTYPE)
                {
                var enabled = d.getObjectValue(key).getBoolean(stringIDToTypeID("enabled"));
                if (!enabled)
                    {
                    var d2 = new ActionDescriptor();
                    var r = new ActionReference();
                    r.putClass(d.getClass(key));
                    r.putIndex(charIDToTypeID("Lyr "), idx + offset);
                    d2.putReference(stringIDToTypeID("null"), r);
                    executeAction(stringIDToTypeID("disableSingleFX"), d2, DialogModes.NO);
                    }
                }
            }
        }
    }
else
    {
    alert("no selected layers")
    }

Thanks! I've tried it, but get the following error message:

- The command "Delete Layer Style" is not currently available.

Line: 40

->

executeAction(stringIDToTypeID("disableSinfleFX"),d2,DialogModes.NO);

Any idea how to fix that?

This can be due to layer protection. Try this variant.

var r = new ActionReference();      
r.putProperty(charIDToTypeID("Prpr"), stringIDToTypeID("targetLayers"));   
r.putEnumerated(charIDToTypeID("Dcmn"), charIDToTypeID("Ordn"), charIDToTypeID("Trgt"));  
if (executeActionGet(r).hasKey(stringIDToTypeID("targetLayers")))  
    {  
    var list = executeActionGet(r).getList(stringIDToTypeID("targetLayers"));  
    var offset = 0;  
    try { activeDocument.backgroundLayer } catch (e) { offset = 1; }  
    var unlock_flag = false;
    var lock = false;
    var del_cnt = 0;
    for (var n = 0; n < list.count; n++)  
        {  
        var idx = list.getReference(n).getIndex();  
        var r = new ActionReference();      
        r.putProperty(charIDToTypeID("Prpr"), stringIDToTypeID("layerEffects"));   
        r.putIndex(charIDToTypeID("Lyr "), idx+offset);  
        if (!executeActionGet(r).hasKey(stringIDToTypeID("layerEffects"))) continue;  
        var d = executeActionGet(r).getObjectValue(stringIDToTypeID("layerEffects"));  
        var r = new ActionReference();      
        r.putProperty(charIDToTypeID("Prpr"), stringIDToTypeID("layerLocking"));   
        r.putIndex(charIDToTypeID("Lyr "), idx+offset);  
        if (!unlock_flag) lock = executeActionGet(r).getObjectValue(stringIDToTypeID("layerLocking")).getBoolean(stringIDToTypeID("protectAll")); 
        for (var i = 0; i < d.count; i++)  
            {  
            var key = d.getKey(i);  
            var type = d.getType(key);  
            if (type == DescValueType.OBJECTTYPE)  
                {  
                var enabled = d.getObjectValue(key).getBoolean(stringIDToTypeID("enabled"));  
                if (!enabled)  
                    {  
                    if (lock && !unlock_flag)
                        {
                        var d2 = new ActionDescriptor();
                        var d1 = new ActionDescriptor();
                        var d3 = new ActionDescriptor();
                        var r = new ActionReference();
                        r.putIndex(charIDToTypeID("Lyr "), idx+offset);  
                        d1.putReference( charIDToTypeID( "null" ), r );
                        d3.putBoolean( stringIDToTypeID( "protectAll" ), false);
                        d2.putObject( stringIDToTypeID( "layerLocking" ), stringIDToTypeID( "layerLocking" ), d3 );
                        d1.putObject( charIDToTypeID( "T   " ), charIDToTypeID( "Lyr " ), d2 );
                        executeAction( charIDToTypeID( "setd" ), d1, DialogModes.NO );
                        unlock_flag = true;
                        }
                    var d2 = new ActionDescriptor();  
                    var r = new ActionReference();  
                    r.putClass(d.getClass(key));  
                    r.putIndex(charIDToTypeID("Lyr "), idx + offset);  
                    d2.putReference(stringIDToTypeID("null"), r);  
                    executeAction(stringIDToTypeID("disableSingleFX"), d2, DialogModes.NO);  
                    ++del_cnt;
                    }  
                }  
            }  
        }  
    alert(del_cnt + " LayerEffects have been removed");  
    }  
else  
    {  
    alert("no selected layers")  
    }

Perfect, thanks a lot!

Are multiple layer effects of the same type accessible through scripting? I looped a file with several gradient overlays for instance, and it didn't see them, trying to figure out what sub object they're contained in.

[c.pfaffenbichler]

Please provide a sample file. 

[Greg von Neulich]

we made a Photoshop plug-in that can do this. The unlimited version is 12$. 

Full Version (12$):
https://exchange.adobe.com/apps/cc/c36e02fb/swift

Trial Version (Limited to 5 Actions):
https://exchange.adobe.com/apps/cc/412c1dcd/swift-trial-version

Its also a big help with getting the layers selected.
