50 | ;; Special handling. |
51 | ;; ----------------- | |
52 | ;; Variables `desktop-buffer-mode-handlers' and `desktop-minor-mode-handlers' | |
53 | ;; are supplied to handle special major and minor modes respectively. | |
54 | ;; `desktop-buffer-mode-handlers' is an alist of major mode specific functions | |
341c2f07 | 55 | ;; to restore a desktop buffer. Elements must have the form |
be617bbf | 56 | ;; |
0f4804e7 | 57 | ;; (MAJOR-MODE . RESTORE-BUFFER-FUNCTION). |
be617bbf | 58 | ;; |
0f4804e7 | 59 | ;; Functions listed are called by `desktop-create-buffer' when `desktop-read' |
341c2f07 | 60 | ;; evaluates the desktop file. Buffers with a major mode not specified here, |
0f4804e7 LH |
61 | ;; are restored by the default handler `desktop-restore-file-buffer'. |
62 | ;; `desktop-minor-mode-handlers' is an alist of functions to restore | |
63 | ;; non-standard minor modes. Elements must have the form | |
be617bbf | 64 | ;; |
0f4804e7 | 65 | ;; (MINOR-MODE . RESTORE-FUNCTION). |
be617bbf | 66 | ;; |
0f4804e7 LH |
67 | ;; Functions are called by `desktop-create-buffer' to restore minor modes. |
68 | ;; Minor modes not specified here, are restored by the standard minor mode | |
69 | ;; function. If you write a module that defines a major or minor mode that | |
70 | ;; needs a special handler, then place code like | |
71 | ||
72 | ;; (defun foo-restore-desktop-buffer | |
73 | ;; ... | |
74 | ;; (add-to-list 'desktop-buffer-mode-handlers | |
75 | ;; '(foo-mode . foo-restore-desktop-buffer)) | |
76 | ||
77 | ;; or | |
78 | ||
79 | ;; (defun bar-desktop-restore | |
80 | ;; ... | |
81 | ;; (add-to-list 'desktop-minor-mode-handlers | |
82 | ;; '(bar-mode . bar-desktop-restore)) | |
83 | ||
fb8a6326 | 84 | ;; in the module itself, and make sure that the mode function is |
341c2f07 | 85 | ;; autoloaded. See the docstrings of `desktop-buffer-mode-handlers' and |
0f4804e7 LH |
86 | ;; `desktop-minor-mode-handlers' for more info. |
87 | ||
88 | ;; Minor modes. | |
89 | ;; ------------ | |
90 | ;; Conventional minor modes (see node "Minor Mode Conventions" in the elisp | |
91 | ;; manual) are handled in the following way: | |
92 | ;; When `desktop-save' saves the state of a buffer to the desktop file, it | |
93 | ;; saves as `desktop-minor-modes' the list of names of those variables in | |
94 | ;; `minor-mode-alist' that have a non-nil value. | |
95 | ;; When `desktop-create' restores the buffer, each of the symbols in | |
96 | ;; `desktop-minor-modes' is called as function with parameter 1. | |
97 | ;; The variables `desktop-minor-mode-table' and `desktop-minor-mode-handlers' | |
98 | ;; are used to handle non-conventional minor modes. `desktop-save' uses | |
99 | ;; `desktop-minor-mode-table' to map minor mode variables to minor mode | |
341c2f07 | 100 | ;; functions before writing `desktop-minor-modes'. If a minor mode has a |
0f4804e7 LH |
101 | ;; variable name that is different form its function name, an entry |
102 | ||
103 | ;; (NAME RESTORE-FUNCTION) | |
104 | ||
105 | ;; should be added to `desktop-minor-mode-table'. If a minor mode should not | |
106 | ;; be restored, RESTORE-FUNCTION should be set to nil. `desktop-create' uses | |
107 | ;; `desktop-minor-mode-handlers' to lookup minor modes that needs a restore | |
108 | ;; function different from the usual minor mode function. | |

111 | ;; By the way: don't use desktop.el to customize Emacs -- the file .emacs |
112 | ;; in your home directory is used for that. Saving global default values | |
113 | ;; for buffers is an example of misuse. | |
114 | ||

115 | ;; PLEASE NOTE: The kill ring can be saved as specified by the variable |
116 | ;; `desktop-globals-to-save' (by default it isn't). This may result in saving | |
117 | ;; things you did not mean to keep. Use M-x desktop-clear RET. | |
