29 | ;; appt.el - visible and/or audible notification of | |
8d638c1b | 30 | ;; appointments from diary file. |
902a0e3c | 31 | ;; |
e1422141 SM |
32 | ;; |
33 | ;; Thanks to Edward M. Reingold for much help and many suggestions, | |
34 | ;; And to many others for bug fixes and suggestions. | |
35 | ;; | |
36 | ;; | |
37 | ;; This functions in this file will alert the user of a | |
38 | ;; pending appointment based on his/her diary file. This package | |
39 | ;; is documented in the Emacs manual. | |
40 | ;; | |
41 | ;; To activate this package, simply use (appt-activate 1). | |
42 | ;; A `diary-file' with appointments of the format described in the | |
43 | ;; documentation of the function `appt-check' is required. | |
44 | ;; Relevant customizable variables are also listed in the | |
45 | ;; documentation of that function. | |
46 | ;; | |
47 | ;; Today's appointment list is initialized from the diary when this | |
12b2a018 | 48 | ;; package is activated. Additionally, the appointments list is |
e1422141 | 49 | ;; recreated automatically at 12:01am for those who do not logout |
12b2a018 | 50 | ;; every day or are programming late. It is also updated when the |
08151ec5 GM |
51 | ;; `diary-file' (or a file it includes) is saved. Calling |
52 | ;; `appt-check' with an argument (or re-enabling the package) forces a | |
53 | ;; re-initialization at any time. | |
e1422141 SM |
54 | ;; |
55 | ;; In order to add or delete items from today's list, without | |
56 | ;; changing the diary file, use `appt-add' and `appt-delete'. | |
57 | ;; | |
58 | ||
59 | ;; Brief internal description - Skip this if you are not interested! | |
60 | ;; | |
61 | ;; The function `appt-make-list' creates the appointments list which | |
62 | ;; `appt-check' reads. | |
63 | ;; | |
64 | ;; You can change the way the appointment window is created/deleted by | |
65 | ;; setting the variables | |
66 | ;; | |
debf91fd | 67 | ;; appt-disp-window-function |
e1422141 | 68 | ;; and |
debf91fd | 69 | ;; appt-delete-window-function |
e1422141 SM |
70 | ;; |
71 | ;; For instance, these variables could be set to functions that display | |
72 | ;; appointments in pop-up frames, which are lowered or iconified after | |
73 | ;; `appt-display-interval' minutes. | |
