Appointments
If you have a diary entry for an appointment, and that diary entry
begins with a recognizable time of day, Emacs can warn you several
minutes beforehand that that appointment is pending. Emacs alerts you
to the appointment by displaying a message in the mode line.
To enable appointment notification, you must enable the time display
feature of Emacs, M-x display-time (see Mode Line). You must
also add the function appt-make-list to the
diary-hook, like this:
(add-hook 'diary-hook 'appt-make-list)
Adding this text to your .emacs file does the whole job:
(display-time)
(add-hook 'diary-hook 'appt-make-list)
(diary 0)
With these preparations done, when you display the diary (either with
the d command in the calendar window or with the M-x diary
command), it sets up an appointment list of all the diary entries found
with recognizable times of day, and reminds you just before each of
them.
For example, suppose the diary file contains these lines:
Monday
9:30am Coffee break
12:00pm Lunch
Then on Mondays, after you have displayed the diary, you will be
reminded at 9:20am about your coffee break and at 11:50am about lunch.
You can write times in am/pm style (with 12:00am standing
for midnight and 12:00pm standing for noon), or 24-hour
European/military style. You need not be consistent; your diary file
can have a mixture of the two styles.
Emacs updates the appointments list automatically just after
midnight. This also displays the next day's diary entries in the diary
buffer, unless you set appt-display-diary to nil.
You can also use the appointment notification facility like an alarm
clock. The command M-x appt-add adds entries to the appointment
list without affecting your diary file. You delete entries from the
appointment list with M-x appt-delete.
You can turn off the appointment notification feature at any time by
setting appt-issue-message to nil.
