GIMP: Hide/Show all layers in current image
View hide-show-layers.scm
;; When editing an image with many layers (e.g. an animated GIF with
;; hundreds of frames), it's impossibly tedious to click hundreds and
;; hundreds of times on small little boxes to hide or show all layers.
;; Since GIMP seems to lack a button to hide/show all of them, and it
;; doesn't allow selection of multiple layers, this script provides
;; menu items to hide/show all layers at once.
;; Who knows if later versions of GIMP than I have provide a way to do
;; this, but this works, and maybe it will be helpful to someone.

alphapapa / dll-fifo.el
Created Jan 1, 2019 — forked from jordonbiondo/dll-fifo.el
A fifo queue in emacs lisp using a cyclic doubly linked list.
View dll-fifo.el
;; FIFO queue implementation using cyclic doubly linked lists
;; This data structure is a bit overkill for a queue,
;; but it has many other uses
;; a doubly linked list cell look like (val . (prev-cell next-cell))
;; a FIFO queue object looks like ('fifo . cyclic-doubly-linked-list)
;; An empty FIFO queue would be: ('fifo . nil)
