I need a script that will add an alpha channel to EVERY layer.
Take any user selection, invert it and then delete it from every layer.
There is one written in Python but for those who do not have python this would be useful.
It would be nice to have the option of delete visible OR delete all also.

Thanks :)

Code:
(define (script-fu-sg-isolate-all-visible image)
  (gimp-image-undo-group-start image)
  (gimp-selection-invert image)
  (let loop ((layers (vector->list (cadr (gimp-image-get-layers image)))))
    (unless (null? layers)
      (unless (zero? (car (gimp-drawable-get-visible (car layers))))
        (gimp-layer-add-alpha (car layers))
        (gimp-edit-clear (car layers)) )
      (loop (cdr layers)) ))
  (gimp-selection-invert image)
  (gimp-image-undo-group-end image)
  (gimp-displays-flush) )

(script-fu-register "script-fu-sg-isolate-all-visible"
   "Isolate All Visible Layers"
  "Remove from all visible layers the unselected region"
  "Saul Goode"
  "saulgoode"
  "March 2012"
  "*"
  SF-IMAGE    "Image"    0
  SF-DRAWABLE "Drawable" 0
  )
(script-fu-menu-register "script-fu-sg-isolate-all-visible"
  "<Image>/Edit/Clear"
  )

You may name the file whatever you wish; as long as it has the .scm extension, GIMP will recognize it (and the filename is otherwise unimportant).

For what it's worth, I have adopted the practice of naming all of my own script files prefixed by "sg-" -- for example, "sg-isolate-all-visible.scm" -- while the corresponding procedures registered with the PDB being prefixed by "script-fu-sg-" (to indicate that the procedure is a Script-fu). My reason for doing this is so that I can (hopefully) determine whether any question that gets posted is about one of my scripts or somebody else's.

Anyone is welcome to modify any of my scripts; though my hope is that they would then change the name of the registered procedure (perhaps prefix their own initials) to avoid the potential for confusion.

Saul !
Thankyou very much for this script Saul. Excellent and so helpful. Just one click and it automatically inverts and clears all frames.
