Org-Mode S-expressions

Org-Mode S-expressions

[Joel J. Adamson]

Howdy,

I'm using Emacs 23.0.0.1 on Slackware Linux 12.0.

I'm trying to set up a unique Org Mode situation here.  I work for two
different researchers, with specific sets of projects for each one.  I
work for Researcher A Monday and Tuesday, and WEdnesday until Noon.
Then I switch over to Researcher B until the end of Friday.  I'd like
these to show up in the Agenda at the specified times and repeat every
day at the appropriate time.  I tried timestamps like

<2007-10-08 Mon 9:00>--<2007-10-10 Wed 12:00>

And the latest is diary-style s-expression, based on one I found in
the Emacs manual for diary:

<%%(let ((dayname (nth 7 (decode-time (current-time))))
         (hour (nth 3 (decode-time (current-time)))))
     (or (memq dayname '(1 2))
         (and (equal dayname 3) (< hour 12))))>

Now, I noticed that the angle-brackets and less-than sign will
probably mix things up.

What's the most effective way to accomplish this?  Please point me to
the best tutorial or explanation for timestamps.

Thanks,
Joel

(nth 7 (decode-time (current-time)))
     ^

... should be 6 no?

I don't know what version of Org you're using but since Org's
development is quite fast it might be a good idea to check the 
lastest release:

  http://orgmode.org/

And maybe you can use Org's own syntax for repeating events:

,----[ (info "(Org)Time stamps") ]
| TIME STAMP WITH REPEATER INTERVAL
|      A time stamp may contain a _repeater interval_, indicating that it
|      applies not only on the given date, but again and again after a
|      certain interval of N days (d), weeks (w), months(m), or years(y).
|      The following will show up in the agenda every Wednesday:
| 
|           * Pick up Sam at school <2007-05-16 Wed 12:30 +1w>
`----

Or maybe check the online manual for this:

7 gave me the hour: that is strange though...

I'm using whichever version is included with Emacs CVS.

Yeah, I tried that and all I get is that it shows up once with a
single time stamp.  I'd rather have it show (metaphorically) "Today is
the day that you're working for Dr. Frankenstein."

Thanks for your help Bastien,
Joel

I mean day...I'll read my own code in the future.

Yes, very strange! 

,----[ decode-time ]
| Decode a time value as (SEC MINUTE HOUR DAY MONTH YEAR DOW DST ZONE).

From memory, that is 4.67c.

I strongly suggest you try the latest Org.  If there is something wrong
with repeating tasks, then please send a bug report to the OrgMode list:
emacs-orgmode@gnu.org - the is *very* active and responsive.

Best,
