|
|
|
32 ;; Save the Desktop, i.e.,
|
|
|
33 ;; - some global variables
|
|
|
34 ;; - the list of buffers with associated files. For each buffer also
|
|
|
35 ;; - the major mode
|
|
|
36 ;; - the default directory
|
|
|
37 ;; - the point
|
|
|
38 ;; - the mark & mark-active
|
|
|
39 ;; - buffer-read-only
|
|
|
40 ;; - some local variables
|
|
|
41
|
|
|
42 ;; To use this, first put these three lines in the bottom of your .emacs
|
|
|
43 ;; file (the later the better):
|
|
|
44 ;;
|
|
|
45 ;; (load "desktop")
|
|
|
46 ;; (desktop-load-default)
|
|
|
47 ;; (desktop-read)
|
|
|
48 ;;
|
|
|
49 ;; Between the second and the third line you may wish to add something that
|
|
|
50 ;; updates the variables `desktop-globals-to-save' and/or
|
|
|
51 ;; `desktop-locals-to-save'. If for instance you want to save the local
|
|
|
52 ;; variable `foobar' for every buffer in which it is local, you could add
|
|
|
53 ;; the line
|
|
|
54 ;;
|
|
|
55 ;; (setq desktop-locals-to-save (cons 'foobar desktop-locals-to-save))
|
|
|
56 ;;
|
|
|
57 ;; To avoid saving excessive amounts of data you may also wish to add
|
|
|
58 ;; something like the following
|
|
|
59 ;;
|
|
|
60 ;; (add-hook 'kill-emacs-hook
|
|
|
61 ;; '(lambda ()
|
|
|
62 ;; (desktop-truncate search-ring 3)
|
|
|
63 ;; (desktop-truncate regexp-search-ring 3)))
|
|
|
64 ;;
|
|
|
65 ;; which will make sure that no more than three search items are saved. You
|
|
|
66 ;; must place this line *after* the (load "desktop") line. See also the
|
|
|
67 ;; variable desktop-save-hook.
|
|
|
68
|
|
|
69 ;; Start Emacs in the root directory of your "project". The desktop saver
|
|
|
70 ;; is inactive by default. You activate it by M-x desktop-save RET. When
|
|
|
71 ;; you exit the next time the above data will be saved. This ensures that
|
|
|
72 ;; all the files you were editing will be reloaded the next time you start
|
|
|
73 ;; Emacs from the same directory and that points will be set where you
|
|
|
74 ;; left them. If you save a desktop file in your home directory it will
|
|
|
75 ;; act as a default desktop when you start Emacs from a directory that
|
|
|
76 ;; doesn't have its own. I never do this, but you may want to.
|
|
|
77
|
|
|
78 ;; By the way: don't use desktop.el to customize Emacs -- the file .emacs
|
|
|
79 ;; in your home directory is used for that. Saving global default values
|
|
|
80 ;; for buffers is an example of misuse.
|
|
|
81
|
|
|
82 ;; PLEASE NOTE: The kill ring can be saved as specified by the variable
|
|
|
83 ;; `desktop-globals-to-save' (by default it isn't). This may result in saving
|
|
|
84 ;; things you did not mean to keep. Use M-x desktop-clear RET.
