Photoshop Script to activate layer in one PSD based on visible layers in another PSD

s2t = stringIDToTypeID;

(r = new ActionReference()).putProperty(s2t('property'), p = s2t('hasBackgroundLayer'));
r.putEnumerated(s2t('document'), s2t('ordinal'), s2t('targetEnum'))
var indexFrom = executeActionGet(r).getBoolean(p) ? 0 : 1;

(r = new ActionReference()).putProperty(s2t('property'), p = s2t('numberOfLayers'));
r.putEnumerated(s2t('document'), s2t('ordinal'), s2t('targetEnum'));
var len = executeActionGet(r).getInteger(p),
    vis = [s2t('hide'), s2t('show')],
    lrs = [];

for (var i = indexFrom; i <= len; i++) {
    (r = new ActionReference()).putProperty(s2t('property'), n = s2t('name'))
    r.putIndex(s2t('layer'), i);
    (r1 = new ActionReference()).putProperty(s2t('property'), v = s2t('visible'))
    r1.putIndex(s2t('layer'), i);
    lrs.push({ name: executeActionGet(r).getString(n), visible: Number(executeActionGet(r1).getBoolean(v)) });
}

(r = new ActionReference()).putOffset(s2t('document'), -1);
(d = new ActionDescriptor()).putReference(s2t('target'), r);
executeAction(s2t('select'), d, DialogModes.NO);

do {
    var cur = lrs.shift();
    (r = new ActionReference()).putName(s2t('layer'), cur.name);
    (d = new ActionDescriptor()).putReference(s2t('target'), r);
    try {executeAction(vis[cur.visible], d, DialogModes.NO)} catch (e){};
} while (lrs.length)

The task seems problematic; how should missing names or multiple Layers of the same name be handled for example? 

How can the comparison-file be identified unequivocally – will there only ever be two images open at the same time? 

Hello

Thank you for your reply

If you can not find one you should create the script you need.  If an Author of such a script is going to make it available for use they will most likely make it available on the web.  If your searching does not fine one you need to create one.   Your description seems to be for PSD that you have designed someone may do something  quite similar so you should look for scripts the may  nearly be what you want.  You may be able to  modify their scripts for your PSD design or modify your PSD design to work with their scripts. Search this forum there are many treads on processing pairs of files. It is not clear what you actually want the script to do your a bit vague there.
