org-agenda-show-current-time-in-grid and automatic refresh

[Kiwon Um]

Dear org users,

The recent function for showing current time in agenda view is quite
cool. I have a question about it. When the agenda view is being shown,
is there any way to refresh it automatically so that makes the current
time line always recent?

Thanks.

I have thought about that, I even worked up a small minor mode for that
(attached). But it doesn't seem to work very well. It updates only the
first time but fails subsequently. I am still a lisp newbie. If someone
could guide me, I could give it another try.

Right now it only updates if any of the agenda file buffers change but I
would also like to put a timer. Then if no agenda files have been edited
in a while (say 5 mins) the agenda buffer is refreshed anyway. But I
don't know how to do that. Any suggestions would be welcome.

Hi!

Just in case you missed the simple "g" in agenda view to update the
view with a single keypress.
Not automatic, but nearly.
 
It took me a long time to discover these single key commands, so may
be someone else finds a reminder useful, too.

You can probably use run-with-timer or run-with-idle-timer to do things
like this, but I'm with Detlef Steuer: pressing 'g' in the agenda to
refresh it is simple and does not consume any extra resources - you do
it when you need to and it's done. I just find the idea of running a
timer in order to update a time line in the agenda every once in a while
somewhat distasteful, but maybe it's just me.

OTOH, I'm being somewhat hypocritical here because I run two visible
clocks: one in the gnome panel and one in the emacs mode line with
display-time. Having three of them however is clearly overkill :-)

Thanks for the hint. I tried it, works fine. But on reflecting on it
some more, I agree with you seems an overkill specially when a simple g
does the job.

I would guess that the simple use of 'g' for refreshing was inspired by the
Emacs buffer list (induced by C-c C-b; you enter "Buffer Menu" mode while in
that *Buffer List* buffer's window).

Discovering 'g' for the buffer list took me a long time, but I was so
delighted when I did.

Thanks. Here is my hack for it. It works fine.

;; in the emacs init file

;; refresh agenda view regurally
(defun kiwon/org-agenda-redo-in-other-window ()
  "Call org-agenda-redo function even in the non-agenda buffer."
  (interactive)
  (let ((agenda-window (get-buffer-window org-agenda-buffer-name t)))
    (when agenda-window
      (with-selected-window agenda-window (org-agenda-redo)))))
(run-at-time nil 300 'kiwon/org-agenda-redo-in-other-window)

I must admit that I would like and use a less simple solution where
only the line with the current time would be updated and if necessary
also moved within the time grid once every minute. I would like it
even additionally to the clock on the OS desktop because the agenda
view current time does not only show the current time itself but also
the current time position within the time grid.

For me it would not be desirable to update also all other agenda view
contents like above without request from the user with `g'. On one
side because it can collide badly with the user while manipulating (e.
g. shift-right several times on an entry) or only moving in the agenda
view and on one side because an overall update can take an
unpredictably large amount of CPU time for a larger set of larger
agenda files.

Hi,

I believe this is superseded by the hack in org-hacks.org, so I have  
marked this patch off on the patchwork server.
