;;; Commentary:
|
|
|
|
;; Get notifications, when there is something to do.
|
|
;; Sometimes, you need a reminder a few days before a deadline, e.g. to buy a
|
|
;; present for a birthday, and then another notification one hour before to
|
|
;; have enough time to choose the right clothes.
|
|
;; For other events, e.g. rolling the dustbin to the roadside once per week,
|
|
;; you probably need another kind of notification strategy.
|
|
;; This package tries to satisfy the various needs.
|
|
|
|
;; In order to activate this package, you must add the following code
|
|
;; into your .emacs:
|
|
;;
|
|
;; (require 'org-notify)
|
|
;; (org-notify-start)
|
|
|
|
;; Example setup:
|
|
;;
|
|
;; (org-notify-add 'appt
|
|
;; '(:time "-1s" :period "20s" :duration 10
|
|
;; :actions (-message -ding))
|
|
;; '(:time "15m" :period "2m" :duration 100
|
|
;; :actions -notify)
|
|
;; '(:time "2h" :period "5m" :actions -message)
|
|
;; '(:time "3d" :actions -email))
|
|
;;
|
|
;; This means for todo-items with `notify' property set to `appt': 3 days
|
|
;; before deadline, send a reminder-email, 2 hours before deadline, start to
|
|
;; send messages every 5 minutes, then 15 minutes before deadline, start to
|
|
;; pop up notification windows every 2 minutes. The timeout of the window is
|
|
;; set to 100 seconds. Finally, when deadline is overdue, send messages and
|
|
;; make noise."
|
|
|
|
;; Take also a look at the function `org-notify-add'.
