Headline with 2 timestamps is displayed only once in the agenda

Headline with 2 timestamps is displayed only once in the agenda

[Tassilo Horn]

Hi all,

I have this entry in an org-file.

--8<---------------cut here---------------start------------->8---
** Übung Grundlagen der Softwaretechnik (B 016)        :teaching:
   <2009-04-22 Wed 08:30-10:00 +1w>
   <2009-04-29 Wed 10:15-11:45> (Für Hannes übernehmen)
--8<---------------cut here---------------end--------------->8---

I expect it to be displayed every wednesday after 2009-04-22 for
08:30-10:00 and on 2009-04-29 it should be displayed twice: one at the
usual time and one for 10:15-11:45.

But the agenda shows only the regular entry (08:30-10:00) and omitts the
exception.  If I reorder the timestamps, so that the exception comes
first, only the exception will be shown on 2009-04-29.  Every other
wednesday shows the regular repeater date.

What do I have to do to make that entry showing up twice on 29th April?

BTW: Is it possible to specify an end date for repeating events?
Currently I just deactivate timestamps when they're obsolete, but
sometimes I'd like to check which appointments I had some month ago.

Bye,
Tassilo

Make the second one a SCHEDULED time stamp, for example.
When Org collects entries for the day, it goes through
the files, once for plain time stamps, once for scheduled,
once for deadlines.  When an entry matches, it stops
looking for timestamps in the same entry.  So you need
to make the stamps of different kind to make them show
up both.

No, except if you use a diary sexp in the time stamp.  But not with
native Org syntax.

Hm, ok, that works.  But what if I have to enter a few other exceptions?
What do other people do in that situation?  Add a subheading with all
exception dates?

Why does org stop with the first match?  Efficiency?  At least I don't
care about that, so if this could be made customizable I wouldn't
object.

Ok, thanks.

Efficiency, and to avoid cluttering if you have recorded
several time stamps in an entry.  See, the problem is that
all these lines will look exactly the same in the agenda,
because they all show the same headline!

However, I do see that your applications, with a different
time-of-day, does in fact make sense.

Anyway, get the latest version and do

    (setq org-agenda-find-multiple-timestamps-per-entry t)

Question to everyone:  Should this be the default?

Carsten, you are incredible!

> Question to everyone:  Should this be the default?

I tend to t.  If an entry has more than one timestamp for a day, then
it looks like an exception to me.  If not, then the entry should have a
better structure, i.e. if it was

--8<---------------cut here---------------start------------->8---
* Some meeting with Hugo
  <2009-04-22 Wed>
  - breakfast <2009-04-22 Wed 09:44>
  - lunch <2009-04-22 Wed 12:44>
--8<---------------cut here---------------end--------------->8---

it should better be:

--8<---------------cut here---------------start------------->8---
* Some meeting with Hugo
  <2009-04-22 Wed>
** breakfast <2009-04-22 Wed 09:44>
** lunch <2009-04-22 Wed 12:44>
--8<---------------cut here---------------end--------------->8---

Or if you don't want the breakfast and lunch in the agenda anyway, one
could use 09:44 or an inactive timestamp instead.

I don't think I ever use more than one timestamp per entry.

As long as there is no noticeable performance hit then I have no
preference for what the default is.

-Bernt

PS. I can't find this variable in the latest git sources so I couldn't
    try it myself to see if there was a noticeable performance hit.

    It seems the variable is really
    org-agenda-skip-additional-timestamps-same-entry instead.

    Toggling this variable doesn't seem to change how long the agenda
    displays for me.

Yes, I went back and forth between these two names.  However,
all the other vriables doing similar stuff are called -skip-,
so I decided to do the same here.  Sorry for the mixup.

It does for me.  With Tassilos original example:

* Übung Grundlagen der Softwaretechnik (B 016)			   :teaching:
  <2009-04-22 Wed 08:30-10:00 +1w>
  <2009-04-29 Wed 10:15-11:45> (Für Hannes übernehmen)

I get either one or two entries on April 29.....

I think Bernt meant that he doesn't notice a difference in how long it
takes till the agenda is displayed.  Same for me, with 5 org-files with
about 2000 lines in total.
