Refile cache expire

Refile cache expire

[Tom]

Caching of refile targets is great, however, I usually have my 
computer and emacs running for several days (I use hibernation),
so sometimes I need to clear the cache manually to have it rebuilt.

How about adding an option to set an expiration time for the refile
cache after which it is cleared automatically and rebuilt again?

For example, I could set the cache to expire after and hour (or a day,
etc.) and then it would be cleared and rebuilt automatically, but only
when the computer is idle for, say, 5 seconds. This way one could have
a pretty up-to-date refile cache all the time and the rebuilding
would happen when emacs is idle, so the use wouldn't even have to
notice the updating process.

I meant 5 minutes, of course.

I'd find automatic regeneration useful.

Another way:

********* [#A] make failed refile reload the cache automatically
You usually want the existing choices for selecting a
headline.  You don't need to regenerate those.  Just the
target locations.

So ideally you would just immediately select it, and if hte
target location is bad, it will regenerate for you and
refile to the correct location for you.

This wouldn't work in my case, because actual refiling is not 
what I'm interested in. I use the GOTO interface of refile 
to jump to to any heading in my org system, so the main point 
for me is having an up-to-date cache of all existing headings, 
so I can jump to them easily with completion.

And because I create new headings all the time, it's important
to have a fairly up-to-date cache.

(BTW, for those who doesn't use refile for goto I recommend
checking it out, because it's an awesome way to traverse your
org empire.)

I think my suggestion works for refile goto.

However, if you add headlines all the time, you will need your
suggestion with ido.

(And yes, refile goto is superb.)

Hi Samuel,

Just FYI, remember it can be accessed by `C-u C-u C-c C-w' (not written in the
description of `org-refile-goto-last-stored' -- maybe because it's using
another way to do the jump than the `16' argument, that is, in this case, it
makes use of `bookmark-jump'... so maybe there are tiny subtle differences?).

Best regards,
  Seb

I just do this.

(defun alpha-org-goto ()
  (interactive)
  (let (org-refile-target-verify-function)
    (alpha-org-goto-1)))
(defun alpha-org-goto-1 ()
  (org-mark-ring-push)
  (message "org mark ring pushed")
  (org-refile 4))

How about using something like this in your .emacs.el:

#+begin_src emacs-lisp
  (setq org-refile-rebuild-cache
    (run-with-idle-timer 600 t
     (lambda ()
      (org-refile-cache-clear)
      (org-refile-get-targets))))
#+end_src

Then you can cancel it with

#+begin_src emacs-lisp
  (cancel-timer org-refile-rebuild-cache)
#+end_src

HTH,
