how to rebuild org agenda while emacs is idle?

[Gregor Zattler <telegraph@gmx.net>]

Hi org-mode users and developers,

org-agenda is great but slow, sticky agenda solves this but gets
stale really fast.  I try to refresh my org-agenda while Emacs is
idle like so:

(defun gz/refresh-agenda-when-idle ()
  "Refresh Agenda while idle."
    (org-agenda-redo 'all))

(setq gz/idle-agenda-timer (run-with-idle-timer 3 t 'gz/refresh-agenda-when-idle))

This should refresh my agenda after 3 seconds of idle time.  But
when I change one of my agenda files (and save it), the change
does not occur in the agenda after 9 seconds of idle time
although the echo area shows "Rebuilding agenda buffer...done"

What's wrong with this settings?


If you want to play with this, use this test.org:
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
(defun gz/refresh-agenda-when-idle ()
  "Refresh Agenda while idle."
    (org-agenda-redo 'all))

(setq gz/idle-agenda-timer (run-with-idle-timer 3 t 'gz/refresh-agenda-when-idle))


; in order to cancel the timer ans start afresh:
(cancel-timer gz/idle-agenda-timer)


* Change this heading and watch the agenda buffer: changing?
<2016-02-13 Sa>--<2036-02-13 Mi>

nd visit it like so:
emacs24 -Q -nw /tmp/nuff.org  --eval '(org-agenda-file-to-front)' --eval '(org-agenda "a")'

The problem is the same with emacs25 and org-mode from git as of
today (but with emacs25 you'll have to arrange the windows
yourself).


Ciao, Gregor
