jump to iso-week in agenda

jump to iso-week in agenda

[Thomas Baumann]

Hi,

I really like the most advanced (pure magic working ...) and easy way of
entering dates in org mode. When answering a phone call it's only a few
keystrokes to jump to the date and settle the appointment. However there
are some people thinking in weeks (iso-week). So when those friends call
it get's much more complicated. Currently when I would like to jump to
say week 46, I might find an old paper calendar or M-x
calendar-goto-iso-week.

How difficult would it be to
(a) add the current iso-week into the headline of the Week-View
(b) include magic jump to a certain week eg. *46 to jump to week 46

Here's another user, who begs for iso-week-display and iso-week-jumps.
Woud be a nice addition.

OK, I will put that in.

That does not work, because the week view may or may not start
on a Monday, so it may contain days from two different weeks.
For now I am adding the ISO week number to every date in the
agenda, if this seems too cluttered we need to think of a
different solution.

> (b) include magic jump to a certain week eg. *46 to jump to week 46

I have just pushed the necessary changes into the git repo.  Here is the
user interface:


Suport for ISO week dates (ISO 8601)
------------------------------------

     Dates in the agenda now show the ISO week and day
     specification, in the form `W08 2', meaning Tuesday of
     week 2.

     The keys `d', `w', `m', and `y' in the agenda view now accept
     prefix arguments.  Remember that in the agenda, you can
     directly type a prefix argument by typing a number, no need
     to press `C-u' first.  The prefix argument may be used to
     jump directly to a specific day of the year, ISO week, month,
     or year, respectively.  For example, `32 d' jumps to February
     1st, `9 w' to ISO week number 9.  When setting day, week, or
     month view, a year may be encoded in the prefix argument as
     well.  For example, `200712 w' will jump to week 12 in
     2007.  If such a year specification has only one or two
     digits, it will be mapped to the interval 1938-2037.

     When entering a date at the date prompt, you may now also
     specify an ISO week.  For example

      w4              Monday of week 4
      fri w4          Friday of week 4
      w4-5            Same as above
      2012 w4 fri     Friday of week 4 in 2012.
      2012-W04-5      Same as above

     So far I have not activated the effect of
     `org-read-date-prefer-future' on this functionality, because
     it seemed too unpredictable for me (as I usually do not know
     which week I am in).  I'd appreciate comments on this
     issue:  Should `org-read-date-prefer-future' also push dates
     into the next year if the week you are entering has already
     passed in the current year?  For consistency I guess this
     should be the case, but I cannot quite wrap my head around
     it.

     I hope but am not entirely convinced that this will behave
     sanely also during the first/last week of a year.  Please
     test extensively and report back.


Enjoy!

Hi Carsten,

thanks you so much for adding the week features, which sometimes are
necessary even inside universities :-)

Hmmh, the view get a little busy, and I don't know about performance
issues when iso weekdays are calculated for each day (speed is an issue
on my N810). There's a lot of redundant information now.



Donnerstag  6 Dezember 2007       W49 4
Freitag    7 Dezember 2007       W49 5

BTW:    (format "%-9s %2d %s %4d   %s"
	        dayname day monthname year weekstring)))

doesn't work as expected for German locale

What about

Week-agenda (W01-02):

if the view does not start on weekday one. Similarly the day/month view
could show:

Day-Agenda (W01):
Month-agenda (W01-05):

I don't think we need weeks for the year view :-)

There seem's to be a problem with '.':

And there's a general problem with emacs23 (which seems to be rather
unstable at the moment): Due to some changes in calendar,
calendar-absolute-from-iso is _not_ autoloaded. (require 'cal-iso) does
the trick.

Definitely, thanks again

Performance is not an issue, certainly not in comparison with the other
stuff that is going on to compute the agenda.

Yes, it is a bit crowded. I'll try to shift this to the heading.
The alternative would be to list the week number only on Mondays.

In what way does it not work?

I think I have fixed this as well, please try again.

Thanks for the quick feedback.

Hi Carsten,

the view is much clearer now, thanks. Personally, I don't need the Week
on Mondays but this is a matter of taste (or customize).

Yes, I already moved most old stuff to archives which are included only
on my desktop.

just an cosmetic issue, "Donnerstag" has 10 letters and does not fit
into "%-9s".

Ah.   Hmmmmm.  I hate locale stuf :-)
