Soo many buffers

Soo many buffers

[Andrea Crotti]

I wrote a discussion like this some time ago and I was pretty happy of
the answer.
But now I changed my settings, and I'm using desktop-mode with one
desktop file for every project.

I also use bookmark+ to jump in the project and load all the buffers,
and everything is great.

The only concern now is about the org-agenda-files (around 200 maybe).

I would like to have them everywhere, so I should add to the "no-clear"
list.
But in this way I lose the advantage of desktop mode and I'm still full
of buffers.

One thing that would be nice I think would be one command to toggle the
visibility of the org buffers on and off.
They can stay always open but I can afford one more click to access them
if they don't stay in the way while I work.

Is there such a shadowing thing somewhere?
Thanks

How about ibuffer and filtering? Some thing like `/ m org-mode' in an
active ibuffer should filter the org-mode buffers. Then you can invert
the filter with `/ !'. Hopefully this helps.

Hi Andrea,

I've had this in my emacs.org for ages

#+begin_src emacs-lisp
  ;; ;; Things that I'm not really interested in seeing in emacs
  ;; ;; (you can still open them explicitly)
  (setq dan/ignored-extensions
        '(".html" ".csv" ".ps" ".bst" ".cls"
          ".fdf" ".spl" ".aux" ".ppt" ".doc" ".xls" ".mp3" ".org"))
  
  (mapc (lambda(extension)
          (add-to-list 'completion-ignored-extensions extension))
          dan/ignored-extensions)
  (ido-mode t) ;; (iswitchb-mode t)
  (setq ido-separator " ")
  
  ;; As regexps, these should really have terminal $
  (mapc (lambda(extension)
          (add-to-list 'ido-ignore-buffers (regexp-quote extension))
          (add-to-list 'ido-ignore-files (regexp-quote extension)))
        dan/ignored-extensions) 
  
  (add-to-list 'ido-ignore-buffers "\\*") ;; if you want *scratch* or *R* just type it
  ;; (add-to-list 'ido-ignore-files "^[^.]+$") ;; files must have a . in their name (experimental)
#+end_src

It prevents C-x b from showing me org files, amongst other things. Note
that org provides C-c b to switch to org buffers only.  The only thing I
don't like is that this prevents C-x C-f from offering org files. I've
wondered whether org should also provide a find-file command for org
files only. I'm sure that's possible to implement in many different ways
with the various completion engines.

It took me some time to realize it but I think ido-mode is smarter than
what I thought.

My filter works, if I do C-x b and tab I don't see any org-file.
BUT if I start to type the name when it matches on one of the org-files
I see it anyway and I can switch to it.
For me it's perfect, even better than what I thought :)

And I don't find any C-c b in org-mode, sure it's not something you
defined yourself??
Thanks

Ah never seen it, and actually in version 7 there is no mention of a
binding (I have the same function but is not bound to C-c b).

Re: Soo many buffers

[Andrea Crotti]

Not yet quite satisfied unfortunately.
Using different desktops for different projects is a neat idea but
unfortunately not really realistic, I then open too many things and it I
can't filter with the damn desktop-clear

--8<---------------cut here---------------start------------->8---
  (setq desktop-clear-preserve-buffers
        (append '("\\.newsrc-dribble" "\\.org$" "eternal" "\\*shell\\*" "\\*group\\*" "\\*ielm\\*") desktop-clear-preserve-buffers))
--8<---------------cut here---------------end--------------->8---

But this looks correct, at least with that regexp the org files should
not be killed, but they are, and that takes forever...

I really think that the best way would be to use one desktop for each
Elscreen.
But I don't find much to play with in elscreen, and the project is
kindof dead apparently.

It would be then great to have
screen 1: project X
screen 2: project Y
screen 3: all the rest

Maybe having some rules in ido to hide or at least prioritize some
buffers.

Andrea,

I have a similar problem and came up with a (mostly) complete solution. I
used elscreen and added the ability to bind a set of buffers to a screen. It
tries its best to hide the buffers from the list depending on the screen
you're on. Its not quite complete and I haven't worked on it in a good while
and don't really consider it done, but I can get the code up somewhere in a
little while.

Some of the things I've done with it is bind all of gud and wanderlust to a
single elscreen. You can bind by path so all files in a subtree are on a
screen. I'm at the dentist now so I'll get to putting the code up later.

WTF?!? How do you structure your projects, i.e. how do you decide to
create a new agenda file?  I only have 4...

At least with `ibuffer' (an advanced alternative to the normal
`list-buffers') you can group buffers, so that you get something looking
like Gnus group buffers with topics.  I also put org-related buffers in
one group.  Here's my definition:

--8<---------------cut here---------------start------------->8---
(setq ibuffer-saved-filter-groups
      '(("default"
         ("Chat" (or
                  (mode . garak-mode)
                  (name . "^\\*Garak\\*$")
                  (mode . rcirc-mode)))
         ("Organization" (or
                          (mode . diary-mode)
                          (mode . org-mode)
                          (mode . org-agenda-mode)))
         ("Gnus & News" (or
                         (mode . message-mode)
                         (mode . bbdb-mode)
                         (mode . mail-mode)
                         (mode . gnus-group-mode)
                         (mode . gnus-summary-mode)
                         (mode . gnus-article-mode)
                         (name . "^\\(\\.bbdb\\|dot-bbdb\\)$")
                         (name . "^\\.newsrc-dribble$")
                         (mode . newsticker-mode)))
         ("Files" (filename . ".*"))
         ("File Management" (or
                             (mode . dired-mode)
                             (mode . shell-mode)))
         ("Documentation" (or
                           (mode . Info-mode)
                           (mode . apropos-mode)
                           (mode . woman-mode)
                           (mode . help-mode)
                           (mode . Man-mode))))))
--8<---------------cut here---------------end--------------->8---

If you want to get git of org-mode buffers for all buffer completion
(C-x b), you could rename all such buffers, so that they start with a
space.  Those are ignored by completion (unless you type a space
literally).

Here's a (only very briefly tested) snippet:

--8<---------------cut here---------------start------------->8---
(defun th-hide-org-buffers (arg)
  "Hide org-mode buffers from completion by prepending a space at the buffer name.
When called with prefix arg (`C-u'), then remove this space again."
  (interactive "P")
  (dolist (b (buffer-list))
    (set-buffer b)
    (when (eq major-mode 'org-mode)
      (rename-buffer
       (if arg 
           (replace-regexp-in-string "^[[:space:]]+" "" (buffer-name))
         (concat " " (buffer-name)))))))
--8<---------------cut here---------------end--------------->8---

Thanks a lot they're both really useful it's what I was looking for.
But ido-mode (with flex matching) is too smart and it still finds them!

In theory I found 
--8<---------------cut here---------------start------------->8---
  (add-to-list 'ido-ignore-buffers "\\.org$")
--8<---------------cut here---------------end--------------->8---
this variable but that regexp doens't work as expected, I still never
get regexp to work at first attempt in emacs...

Aren't you escaping your \ with the double \\? Then it inidicates that
the buffer name starts with a literal \ followed by some character
followed by the text "org". Mind you, regex isn't my strong suit,
either... :P

Yes you're right, but for example this is correct
--8<---------------cut here---------------start------------->8---
  (add-to-list 'auto-mode-alist
               '("\\.yaml$" . yaml-mode))
--8<---------------cut here---------------end--------------->8---

if I understood you have to escape once in interactive commands while
twice in non-interctive ones.

Anyway I'm still not so happy, because I managed to filter out the
org-files, but I still want to access to them.

Maybe I could add another key combination that list me the org files and
allows to access to them, but I have then to get used to it also.

I have so many org-files because for example many assignments are also there..

Hi you could try anything, its much better than ido imho.
