Hello
Some days ago I wrote that appt.el would not annotate diary entries
which contain the diary-nonmarking-symbol (ordinarily `&').
I digged into appt.el and the culprit is the
appt-make-list funtion
After changing
(while (string-match
"\\`[ \t\n]*\\([0-9]?[0-9]\\(:[0-9][0-9]\\)?[
\t]*\\(am\\|pm\\)?\\|noon\\|midnight\\|midnite\\).*$"
time-string))
TO
(while (or (string-match
"\\`[ \t\n]*\\([0-9]?[0-9]\\(:[0-9][0-9]\\)?[
\t]*\\(am\\|pm\\)?\\|noon\\|midnight\\|midnite\\).*$"
time-string)
(string-match
"\\`[ \t\n]*\\(\&[0-9]?[0-9]\\(:[0-9][0-9]\\)?[
\t]*\\(am\\|pm\\)?\\|noon\\|midnight\\|midnite\\).*$"
time-string))
It worked, that is such entries are added. However there is a problem
diary-nonmarking-symbol is a variable set to & per default. So if
somebody would modify this variable the above modification would not
work. I don't know how to pass the value of this variable to this
string, could somebody with lisp knowledge give me a hint.

Uwe,
Just as a heads up, I am in the process of synching up the whole
calendar package with Emacs CVS. It's been about 3 yrs, so it's
taking awhile
Appt has been a problem for awhile because the XEmacs version had
really digressed from the Emacs version. It has really gotten to
the point that it extremely difficult to try and sync them. As a
result I am pretty doing a hard-sync with the Emacs version. Appt
will end up looking pretty much like the Emacs version as I am
goint to toss a lot of the cruft. I am trying to keep what I can,
but it is really getting to the point that incorporating bug
fixes/new features from Emacs became next to impossible.
People that use appt "out of the box" will probably not notice much
difference. I am sure there will be a short period of pain for
anyone that has really done a lot of tinkering with their appt
setup. I am sorry about that and I'm trying to minimize it, but I
am more interested in the long-term maintainability of the code.

Hello Jeff
I am glad to hear that there is somebody who takes responsibility for
appt and calendar, (I think I tried almost everybody on the author
list of the Xemacs apptl.el, without success). I admit I have not
tried the Emacs appt version, since my last serious contact with GNU
emacs was pre Mule 19.34.
Can you just tell me the relevant differences (or send me appt.el)?
Right now I am pretty happy with my kludge, although it is highly
insufficient. How does the emacs version deal with this problem.

well, there have been a LOT of changes to the whole calendar package
in Emacs since then. It might be an interesting experiment to see if
your problem got fixed along the way.

From you previous message, I don't think it does. If we can come
up
with a clean fix for Emacs, then it will ultimately be easy to
incorporate into the upcoming synch. I have not had the time to try
and duplicate your problem report or your fix.
Here is appt.el as I currently have it. It is lightly tested at the
moment and still has a bit of garbage to get cleaned up. Please let
me know if you have any problems.

;;
;; 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 their diary file.
;;;
;;; ******* It is necessary to invoke 'display-time' and ********
;;; ******* 'appt-initialize' for this to work properly. ********
;;;
;;; A message will be displayed in the mode line of the Emacs buffer
;;; and (if you request) the terminal will beep and display a message
;;; from the diary in the mini-buffer, or you can choose to
;;; have a message displayed in a new buffer.
;;;
;;; Variables of note:
;;;
;;; appt-issue-message If this variable is nil, then the code in this
;;; file does nothing.
;;; appt-msg-countdown-list Specifies how much warning you want before
;;; appointments.
;;; appt-audible Whether to beep when it's notification-time.
;;; appt-display-mode-line Whether to display a countdown to the next
;;; appointment in the mode-line.
;;; appt-announce-method The function used to do the notifications.
;;; 'appt-window-announce do it in a pop-up window.
;;; 'appt-frame-announce do it in a pop-up frame (v19 only)
;;; 'appt-message-announce do it in the echo area.
;;; 'appt-persistent-message-announce do it in the echo area, but make the
;;; messages not go away at the next keystroke.
;;; appt-display-duration If appt-announce-method is set to the function
;;; 'appt-window-announce, this specifies how many
;;; seconds the pop-up window should stick around.
;;;
;;; In order to use this, create a diary file, and add the following to your
;;; .emacs file:
;;;
;;; (require 'appt)
;;; (display-time)
;;; (appt-initialize)
;;;
;;; If you wish to see a list of appointments, or a full calendar, when emacs
;;; starts up, you can add a call to (diary) or (calendar) after this.
;;;
;;; 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.
;;;
;;; In order to interactively add or delete items from today's list, use
;;; Meta-x appt-add and Meta-x appt-delete. (This does not modify your
;;; diary file, so these will be forgotten when you exit emacs.)
;;;
;;; Additionally, the appointments list is recreated automatically
;;; at 12:01am for those who do not logout every day or are programming
;;; late.
;;;
;;; You can have special appointments which execute arbitrary code rather than
;;; simply notifying you -- sort of like the unix "cron" facility. The syntax
;;; for this is borrowed from the Calendar's special-date format. If you have
;;; a diary entry like
;;;
;;; Monday
;;; 3:00am %%(save-all-modified-buffers)
;;;
;;; then on monday at 3AM, the function `save-all-modified-buffers' will be
;;; invoked. (Presumably this function is defined in your .emacs file.)
;;; There will be no notification that these "special" appointments are being
;;; triggered, unless the form evaluated produces a notification.
;;;
;;; It is necessary for the entire list after the "%%" to be on one line in
;;; your .diary file -- there may not be embedded newlines in it. This is a
;;; bit of a misfeature.
;;;
;;; This also interacts correctly with Benjamin Pierce's reportmail.el package.
;;;
;;; Brief internal description - Skip this if you are not interested!
;;;
;;; The function appt-initialize invokes 'diary' to get a list of today's
;;; appointments, and parses the lines beginning with date descriptions.
;;; This list is cached away. 'diary' is invoked in such a way so as to
;;; not pop up a window displaying the diary buffer.
;;;
;;; The function appt-check is run from the 'loadst' process (or the
'wakeup'
;;; process in emacs 18.57 or newer) which is started by invoking display-time.
;;; It checks this cached list, and announces as appropriate. At midnight,
;;; appt-initialize is called again to rebuild this list.
;;;
;;; display-time-filter is modified to invoke appt-check.
;;;
;;; TO DO:
;;;
;;; o multiple adjacent appointments are not handled gracefully. If there
;;; is an appointment at 3:30 and another at 3:35, and you have set things
;;; up so that you get a notification twenty minutes before each appt,
;;; then a notification should come at 3:10 for the first appt, and at
;;; 3:15 for the second. Currently, no notifications are generated for an
;;; appointment until all preceding appointments have completely expired.
;;;
;;; o If there are two appointments at the same time, all but the first are
;;; ignored (not announced.)
;;;
;;; o Appointments which are early enough in the morning that their
;;; announcements should begin before midnight are not announced until
;;; midnight.
;;;
;;; o There should be some way to mark certain appointments as "important,"
;;; so that you will be harassed about them even after they have expired.
;;; Code:
;; Make sure calendar is loaded when we compile this.

`appt-visible'
Variable used to determine if appointment message should be
displayed in the mini-buffer. Default is t.
`appt-msg-window'
Variable used to determine if appointment message
should temporarily appear in another window. Mutually exclusive
to `appt-visible'.
`appt-display-duration'
The number of seconds an appointment message

one provided with this package.
`appt-delete-window-function'
Function called to remove appointment window and buffer. You can
customize appt.el by setting this variable to a function different
from the one provided with this package.
appt-msg-countdown-list Specifies how much warning you want before
appointments.
appt-display-mode-line Whether to display a countdown to the next
appointment in the mode-line.
appt-announce-method The function used to do the notifications.
'appt-window-announce to do it in a pop-up
window, 'appt-message-announce or
'appt-persistent-message-announce to do it
in the echo-area.
This function is run from the `loadst' or `wakeup' process for display-time.
