- ; appt.el is an appointment notification system, to be used
- ; in conjunction Edward M. Reingold's calendar.el. It
- ; will notify users of pending appointments based upon their
- ; diary file (see calendar.el if your not sure about a diary
- ; file). The header of the file below describes what needs
- ; to be in your .emacs file in order to use this.

- ;;; This file will alert the user of a pending appointment based on their
- ;;; diary file.
- ;;;
- ;;; ******* It is necessary to invoke 'display-time' ********
- ;;; ******* and 'diary' for this to work properly. ********
- ;;;
- ;;; A message will be displayed in the mode line of the emacs buffer
- ;;; and (if the user desires) the terminal will beep and display a message
- ;;; from the diary in the mini-buffer, or the user may select to
- ;;; have a message displayed in a new buffer.
- ;;;
- ;;; The variable 'appt-message-warning-time' allows the
- ;;; user to specify how much notice they want before the appointment. The
- ;;; variable 'appt-issue-message' specifies whether the user wants
- ;;; to to be notified of a pending appointment.
- ;;;
- ;;; In order to use, the following should be in your .emacs file in addition to
- ;;; creating a diary file and invoking calendar:
- ;;;
- ;;; Set some options
- ;;; (setq view-diary-entries-initially t)
- ;;; (setq issue-appointments-message t)
- ;;;
- ;;; The following three lines are required:
- ;;; (display-time)
- ;;; (autoload 'appt-make-list "appt.el" nil t)
- ;;; (setq list-diary-entries-hook
- ;;; (list 'appt-make-list 'prepare-fancy-diary-buffer))
- ;;;
- ;;;
- ;;; This is an example of what can be in your diary file:
- ;;; Monday
- ;;; 9:30am Coffee break
- ;;; 12:00pm Lunch
- ;;;
- ;;; Based upon the above lines in your .emacs and diary files,
- ;;; the calendar and diary will be displayed when you enter
- ;;; emacs and your appointments list will automatically be created.
- ;;; You will then be reminded at 9:20am about your coffee break
- ;;; and at 11:50am to go to lunch.
- ;;;
- ;;; Use describe-function on appt-check for a description of other variables
- ;;; that can be used to personalize the notification system.
- ;;;
- ;;; In order to add or delete items from todays list, use appt-add
- ;;; and appt-delete.
- ;;;
- ;;; Additionally, the appointments list is recreated automatically
- ;;; at 12:01am for those who do not logout every day or are programming
- ;;; late.
- ;;;
- ;;; Brief internal description - Skip this if your not interested!
- ;;;
- ;;; The function appt-check is run from the 'loadst' process which is started
- ;;; by invoking (display-time). A function below modifies display-time-filter
- ;;; (from original time.el) to include a hook which will invoke appt-check.
- ;;;
- ;;; NOTE: If this is included in the gnuemacs distribution, the original
- ;;; time.el should be modified.
- ;;;
- ;;; The function appt-make-list creates the appointments list which appt-check
- ;;; reads. This is all done automatically.
- ;;; It is invoked from the function list-diary-entries.
