29 | ;; Save the Desktop, i.e., |
30 | ;; - some global variables | |
31 | ;; - the list of buffers with associated files. For each buffer also | |
32 | ;; - the major mode | |
33 | ;; - the default directory | |
34 | ;; - the point | |
35 | ;; - the mark & mark-active | |
36 | ;; - buffer-read-only | |
ec4c6f22 | 37 | ;; - some local variables |
6343ed61 | 38 | |
478653c9 | 39 | ;; To use this, first put these two lines in the bottom of your .emacs |
0b9bd504 RS |
40 | ;; file (the later the better): |
41 | ;; | |
0b9bd504 RS |
42 | ;; (desktop-load-default) |
43 | ;; (desktop-read) | |
44 | ;; | |
47640244 GM |
45 | ;; Between these two lines you may wish to add something that updates the |
46 | ;; variables `desktop-globals-to-save' and/or `desktop-locals-to-save'. If | |
47 | ;; for instance you want to save the local variable `foobar' for every buffer | |
48 | ;; in which it is local, you could add the line | |
ec4c6f22 RS |
49 | ;; |
50 | ;; (setq desktop-locals-to-save (cons 'foobar desktop-locals-to-save)) | |
51 | ;; | |
f4c73d07 | 52 | ;; To avoid saving excessive amounts of data you may also wish to add |
ec4c6f22 RS |
53 | ;; something like the following |
54 | ;; | |
55 | ;; (add-hook 'kill-emacs-hook | |
de9e2828 | 56 | ;; '(lambda () |
ec4c6f22 RS |
57 | ;; (desktop-truncate search-ring 3) |
58 | ;; (desktop-truncate regexp-search-ring 3))) | |
59 | ;; | |
60 | ;; which will make sure that no more than three search items are saved. You | |
47640244 GM |
61 | ;; must place this line *after* the `(desktop-load-default)' line. See also |
62 | ;; the variable `desktop-save-hook'. | |
6343ed61 | 63 | |

64 | ;; Start Emacs in the root directory of your "project". The desktop saver |
65 | ;; is inactive by default. You activate it by M-x desktop-save RET. When | |
66 | ;; you exit the next time the above data will be saved. This ensures that | |
67 | ;; all the files you were editing will be reloaded the next time you start | |
68 | ;; Emacs from the same directory and that points will be set where you | |
ec4c6f22 | 69 | ;; left them. If you save a desktop file in your home directory it will |
de9e2828 | 70 | ;; act as a default desktop when you start Emacs from a directory that |
ec4c6f22 RS |
71 | ;; doesn't have its own. I never do this, but you may want to. |

73 | ;; Some words on minor modes: Most minor modes are controlled by |
74 | ;; buffer-local variables, which have a standard save / restore | |
75 | ;; mechanism. To handle all minor modes, we take the following | |
76 | ;; approach: (1) check whether the variable name from | |
77 | ;; `minor-mode-alist' is also a function; and (2) use translation | |
78 | ;; table `desktop-minor-mode-table' in the case where the two names | |
79 | ;; are not the same. | |
80 | ||
ec4c6f22 RS |
81 | ;; By the way: don't use desktop.el to customize Emacs -- the file .emacs |
82 | ;; in your home directory is used for that. Saving global default values | |
83 | ;; for buffers is an example of misuse. | |
84 | ||
0b9bd504 RS |
85 | ;; PLEASE NOTE: The kill ring can be saved as specified by the variable |
86 | ;; `desktop-globals-to-save' (by default it isn't). This may result in saving | |
87 | ;; things you did not mean to keep. Use M-x desktop-clear RET. | |
