Packages to manage window layouts

The following libraries are useful for preserving window layout within frames (but not the buffers within windows). Note: if the frame is deleted, configurations recorded by winner-mode and elscreen are lost.

elscreen

Rather than using multiple frames, Elscreen can be used to manage simultaneous window configurations in a single (optionally tabbed) frame. Keybindings

APEL and elscreen should be installed. Setup here.

The following is just FYI as it is already implemented in the aprl-emacs confuration. I think there is a comparison of windows configurations between the return value of (elscreen-get-window-configuration) and the prior value saved from (elscreen-set-window-configuration). The latter function is not called when the screen is resized, so elscreen tries to redraw the frame (redraw-frame) with every keystroke.

There is probably a more elegant fix, but this just cycles through all the elscreen tabs so that the window-configuration is synced with the present frame and window geometries.

(defun elscreen-reset ()
  "Cycles through screens so that window configurations are reset 
(prevents flashing from redraw-frame[?] after each keystroke)"
  (interactive)
  ;; only happens when number of screens > 1
  (when (> (elscreen-get-number-of-screens) 1)
    (let* ((screen-list (elscreen-get-screen-list))
           (current-screen (elscreen-get-current-screen))
           (screen-seq (append (delq current-screen screen-list)
                               (list current-screen))))
      (mapc 'elscreen-goto screen-seq))))

;; define keybinding
(define-key elscreen-map "r" 'elscreen-reset)

winner-mode

Setup here.

Winner-mode recalls (one of past 60) frames in current context.

The relevant keybindings are:

keybinding function
C-c <left> (winner-redo)
C-c <right> (winner-undo)

registers

keybinding elisp function
C-x r w r (window-configuration-to-register)
C-x r f r (frame-configuration-to-register)

To recall one of these configuration, use jump-to-register (C-x r j r).

See section on registers for more information.
