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' (or a file it includes) is saved. Calling ;; `appt-check' with an argument (or re-enabling the package) 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, you could be set them ;; to functions that display appointments in pop-up frames, which are ;; lowered or iconified after `appt-display-interval' minutes. ;; ;;; Code: (require 'diary-lib) (defgroup appt nil "Appointment notification." :prefix "appt-" :group 'calendar) (defcustom appt-message-warning-time 12 "Default time in minutes before an appointment that the warning begins.
