;;; Commentary:
|

|
;;
|
||
|
;; This library contains both user level commands and options and
|
||
|
;; functions for use in other elisp libraries.
|
||
|
;;
|
||
|
;;;; User level commands and options
|
||
|
;;
|
||
|
;; The user level commands and options are for saving frame, windows
|
||
|
;; and buffers between Emacs sessions. To do that you can customize
|
||
|
;; the options `desktop-save-mode' and `winsav-save-mode' or put this
|
||
|
;; at the end of your .emacs:
|
||
|
;;
|
||
|
;; (desktop-save-mode 1)
|
||
|
;; (winsav-save-mode 1)
|
||
|
;;
|
||
|
;; You can also save configurations that you later switch between.
|
||
|
;; For more information see the command `winsav-save-mode'.
|
||
|
;;
|
||
|
;; (There is also a command in this library for rotating window
|
||
|
;; borders in a frame, `winsav-rotate'. It is here just because the
|
||
|
;; needed support functions lives here.)
|
||
|
;;

|
;;
|
||
|
;;
|
||
|
;;;; Commands for other elisp libraries
|
||
|
;;
|
||
|
;; This library was orignally written to solve the problem of adding a
|
||
|
;; window to the left of some windows in a frame like the one below
|
||
|
;;
|
||
|
;; ___________

|
||
|

|

|
;; so that the window structure on the frame becomes

|

|
||
|
;;
|
||
|
;; This problem can be solved by this library. However the solution in
|
||
|
;; this library is a bit more general: You first copy the window
|
||
|
;; structure and then restore that into another window. To do the
|
||
|
;; above you first copy the window structure in the first frame above
|
||
|
;; with `winsav-get-window-tree'. Then you create windows like this:
|
||
|
;;
|
||
|

|
;; | R| |
|
||
|
;; |__|______|
|
||
|
;;
|
||
|
;;
|
||
|
;; Finally you use `winsav-put-window-tree' to put the window
|
||
|
;; structure into the right window. (Of course you could have put BAR
|
||
|
;; above, under etc.)

|
||
|
;; Bugs and limitations:
|
||
|
;;
|
||
|
;; Juanma Barranquero has pointed out there is a serious limitation in
|
||
|
;; this way of doing it when overlays with 'window properties are
|
||
|
;; used. The problem is that any pointers to windows are made invalid
|
||
|
;; since they are deleted. So in fact any code that relies on saved
|
||
|
;; pointers to windows will have problem if the window is one of those
|
||
|
;; that are involved here.
|
||
|
;;
|
||
|
;; To overcome this problem when doing something like inserting a BAR
|
||
|
;; window (see above) a new window has to be inserted in the existing
|
||
|
;; window tree on a frame in a way that is currently not supported in
|
||
|
;; Emacs.
|
||
|
;;
|
||
|
;; It would be nice to be have primitives to manipulate the window
|
||
|
;; tree more generally from elisp. That requires implementation of
|
||
|
;; them at the C level of course.
|
||
|
;;
|
||
|
;; However it is probably much easier to implement it quite a bit less
|
||
|
;; general. The concept of splitting is maybe then the right level to
|
||
|
;; search for primitives at.
|
||
|
;;
|
||
|
;; My conclusion is that it will take some time to find suitable
|
||
|
;; primitives for this.
