41 | ;; following line somewhere in your .emacs file: | |

48 | ;; When the desktop module is loaded, the function `desktop-kill' is | |
49 | ;; added to the `kill-emacs-hook'. This function is responsible for | |
50 | ;; saving the desktop when Emacs is killed. Furthermore an anonymous | |
51 | ;; function is added to the `after-init-hook'. This function is | |
52 | ;; responsible for loading the desktop when Emacs is started. | |

54 | ;; Some words on minor modes: Most minor modes are controlled by |
55 | ;; buffer-local variables, which have a standard save / restore | |
56 | ;; mechanism. To handle all minor modes, we take the following | |
57 | ;; approach: (1) check whether the variable name from | |
58 | ;; `minor-mode-alist' is also a function; and (2) use translation | |
59 | ;; table `desktop-minor-mode-table' in the case where the two names | |
60 | ;; are not the same. | |
61 | ||
ec4c6f22 RS |
62 | ;; By the way: don't use desktop.el to customize Emacs -- the file .emacs |
63 | ;; in your home directory is used for that. Saving global default values | |
64 | ;; for buffers is an example of misuse. | |
65 | ||
0b9bd504 RS |
66 | ;; PLEASE NOTE: The kill ring can be saved as specified by the variable |
67 | ;; `desktop-globals-to-save' (by default it isn't). This may result in saving | |
68 | ;; things you did not mean to keep. Use M-x desktop-clear RET. | |
