Photoshop Javascript

This is not updated frequently! I rarely use photoshop and even less script it.

If you want an old overview here's a tutorial I wrote a thousand years ago on scripting in Photoshop: https://www.kirupa.com/motiongraphics/ps_scripting.htm

Launch an action using the name of the current document

Save as .jsx and launch from File>Script in photoshop

/* An example of how you can use the name of a document to launch an action that shares the same name
    try it on an image called 'Gradient Map.jpg' -- since 'Gradient Map is a default action in the 'Default Actions' set it should work on a brand new photoshop
 */

//this gets the name of the current open (foremost document)
currentImage = app.activeDocument.name ;

//this removes the extension
currentImageName = currentImage.substring(0, currentImage.lastIndexOf('.')) || currentImage ;

//this calls an action with the name of the current image from the 'Default Actions' set (which you can of course change)
app.doAction( currentImageName ,'Default Actions');

All documents to current document

docs = app.documents;
ad= app.activeDocument;
for(i = 0;i<docs.length;i++){
    if(docs[i]!=ad){
        activeDocument = docs[i];
        docs[i].selectAll;
        docs[i].layers[0].copy(); 
        activeDocument = ad;
        ad.paste();
     }
}
while(docs.length>1){
    //hackish but works
    for(i = 0;i<docs.length;i++){
        if(docs[i]!=ad){
            docs[i].close(SaveOptions.DONOTSAVECHANGES); 
        }
    }
}

Incremental Save

// incrementalsave
//
// checks if there is a double underscore in filename, if not adds them starting at 0001 
// else increments and saves as 24bit png (filename__####.png) in the doc's folder
//
