;; appt.el - visible and/or audible notification of
|
|
;; appointments from diary file.
|
|
;;
|
|
;;;
|
|
;;; Thanks to Edward M. Reingold for much help and many suggestions,
|
|
;;; And to many others for bug fixes and suggestions.
|
|
;;;
|
|
;;;
|
|
;;; This functions in this file will alert the user of a
|
|
;;; pending appointment based on his/her diary file. This package
|
|
;;; is documented in the Emacs manual.
|
|
;;;
|
|
;;; To activate this package, simply use (appt-activate 1).
|
|
;;; A `diary-file' with appointments of the format described in the
|
|
;;; documentation of the function `appt-check' is required.
|
|
;;; Relevant customizable variables are also listed in the
|
|
;;; documentation of that function.
|
|
;;;
|
|
;;; Today's appointment list is initialized from the diary when this
|
|
;;; package is activated. Additionally, the appointments list is
|
|
;;; recreated automatically at 12:01am for those who do not logout
|
|
;;; every day or are programming late. It is also updated when the
|
|
;;; `diary-file' is saved. Calling `appt-check' with an argument forces
|
|
;;; a re-initialization at any time.
|
|
;;;
|
|
;;; In order to add or delete items from today's list, without
|
|
;;; changing the diary file, use `appt-add' and `appt-delete'.
|
|
;;;
|
|
|
|
;;; Brief internal description - Skip this if you are not interested!
|
|
;;;
|
|
;;; The function `appt-make-list' creates the appointments list which
|
|
;;; `appt-check' reads.
|
|
;;;
|
|
;;; You can change the way the appointment window is created/deleted by
|
|
;;; setting the variables
|
|
;;;
|
|
;;; appt-disp-window-function
|
|
;;; and
|
|
;;; appt-delete-window-function
|
|
;;;
|
|
;;; For instance, these variables could be set to functions that display
|
|
;;; appointments in pop-up frames, which are lowered or iconified after
|
|
;;; `appt-display-interval' minutes.
|
|
;;;
|
|
|
|
;;; Code:
|
|
|
|
;; Make sure calendar is loaded when we compile this.

|
;; roundabout way of loading this file. This file used to have code at
|
|
;; the top-level that set up the appt-timer and global-mode-string.
|

|

;; convention that just loading an Emacs package should not activate
|
|
;; it. Instead, we make appt-make-list activate the package (after a
|
|
;; suggestion from rms). This means that one has to call diary in
|
|
;; order to get it to work, but that is in line with the old (weird,
|
|
;; IMO) documented behavior for activating the package.
|
|
;; Actually, since (diary 0) does not run diary-hook, I don't think
|
|
;; the documented behavior in Emacs-21.3 would ever have worked.
