Org Agenda - revert all agenda files?

Org Agenda - revert all agenda files?

[Xin Shi]

[-- Attachment #1: Type: text/plain, Size: 427 bytes --]

Hello Experts,

In the *Org Agenda* buffer, I usually use the key "r" to refresh the
content. If some of the agenda files have change from the disk, it will pop
up the question in the mini-buffer to ask what to do. As I choose "r" to
revert most of the time, and I have to do several times to revert all the
related agenda files. I'm wondering if there is a command to revert all
agenda files? Or "force revert"?

Thanks!

Xin

why don't you use "g" ? (ah I've just read it is the same)

however I am not asked what to do both with r and g). Org rebuilts the agenda reading from disk.
Do you have some configuration for asking?

Org-mode version 7.8.11 (eed478ffa @ 
GNU Emacs 24.1.1 (i386-mingw-nt6.1.7601) of 2012-06-10 on MARVIN


cheers,
Giovanni

Hi Giovanni,

Thanks for your quick response. You're right that g and r are the same
thing. To reproduce what my problem, one has to change the file not inside
the Emacs of org-mode, such as in a terminal (the senario is that the files
are updated remotely and controlled by VC) . For example, a.org is one of
the agenda files, one can do in terminal:

$ echo "Additional line to test" >> a.org

Then, inside the *Org Agenda* buffer, press "g" or "r" will show:

a.org changed on disk; really edit the buffer? (y, n, r or C-h)

Xin

Hi.

You could do what I do and run global-auto-revert-mode.

There are times when you might wish that you didn't use this: I have on
some occasions mangled a file outside of emacs, but I still had the
buffer with the all-important contents in emacs, so I was able to avert
catastrophe: iiuc, global auto-revert would revert the buffer from the
file on disk, eliminating the possibility of undoing the mistake.

On the OP's question, I'd prefer a more targeted solution: something
like this should work (very lightly tested - check the doc for
revert-without-query if you want to modify the regexp):

--8<---------------cut here---------------start------------->8---
(defun xin-shi-org-revert-agenda-buffers ()
  (interactive)
  (mapcar
   (lambda (file)
     (let ((revert-without-query '(".*\.org$")))
       (find-file file)
       (revert-buffer)))
   org-agenda-files))
--8<---------------cut here---------------end--------------->8---

The variable org-agenda-files can also contain directories.  Therefore
you should use the function call

   (org-agenda-files t)

to get a list of the files.  The t means, even if the agenda
is currently restricted, get all files.

Another improvement to this function would be to limit it
to files currently visited - but I guess this is a minor issue
as the next agenda command will visit all those files anyway.

Thanks - I forgot all about that.

Yes, I thought about that and decided it wasn't worth worrying about.
As Kernighan and Plauger say: first get it right, then make it fast; and
as we just saw, it wasn't right :-). But for typical setups - a few
files or a few dozen files - I don't think it's going to make much
difference. OTOH, if one has thousands of agenda files, then one
probably has much worse problems than this.

Dear all,

Thanks for your kind reply! Sorry that I didn't have chance to check till
now.

OKay, I added the function:

(defun sx-org-revert-agenda-buffers ()
  (interactive)
  (mapcar
   (lambda (file)
     (let ((revert-without-query '(".*\.org$")))
       (find-file file)
       (revert-buffer)))
   (org-agenda-files t)))

It works ! Thanks a lot!

Xin
