Option for saving all buffers always?

Option for saving all buffers always?

[Lars Ingebrigtsen]

I just realised that I have never in the history of ever said "n" to the
question "Save file ...?"  So I wondered whether there was any easy way
to make `save-some-buffers' always save everything.  (The question is
especially annoying when compiling/grepping for stuff.)

But there doesn't seem to be.  I could add an advice to the function to
pass in the always-save parameter, but this strikes me as something that
I think other users will want, too.

Does this seem like a useful addition?  If so, what would this variable
be called?  `save-all-buffers-without-query'?

That variable is just to make `save-some-buffers' skip some buffers
altogether when saving -- it's not about prompting.

I guess (setq-default buffer-save-without-query t) might work though.

That will make Emacs offer to save even the buffers that aren't
connected to files.  :-)

Hah, you're right. Maybe

(add-hook 'find-file-hook (lambda () (setq buffer-save-without-query t)))

buffer-file-name can change any time.

It's probably easiest to advice save-some-buffers and make arg always be
non-nil.

You can just "!" to approve all saves -- that doesn't seem that annoying.

FWIW, while I agree with you, I say `n' relatively often (say, a few
time a week).  Maybe 1% of the cases, but still.  (Doesn't make your
request any less reasonable, of course.)

Just a datapoint.

It's annoying to me.  :-)

But there didn't seem to be a general clamouring for this functionality,
so I just went with advice instead.  For future duckduckgoing, here's
the necessary incantation:

(advice-add 'save-some-buffers :around
	    (lambda (oldfun &optional arg pred)
	      (funcall oldfun t pred)))

I did the same thing many moons ago. It's easy enough to do, and a good
skill to have; i don't think we need yet another global setting for this.

Patching M-x compile and M-x rgrep to only prompt about files within the current directory or its descendants has been on my TODO-list for a long time.

+1

I actually used a patched Magit to do this, until they added the feature
(or I submitted it, dunno).

Actually, as it is common to have multi-level source trees and the build
can be invoked from anywhere, the feature needs a method to determine
the root directory. Assuming that the interesting buffers are on the
current directory or its descendants is ok for rgrep, but not for
compile.

You can take inspiration from pcl-cvs (for which I extended the
argument of save-some-buffer).

I never thought of this; it's rather good and efficient. I've been
doing something different:

(define-key global-map "\C-x\C-c" 'rjn-kill-emacs-quietly)

and in the function 'rjn-kill-emacs-quietly I have a number of things including

(save-some-buffers 1 t)

as well as things to close out gnus cleanly, and finally

(kill-emacs)

I guess the big difference is that M-x kill-emacs won't alter default
exit behavior while C-x C-c will now ensure buffers are saved, etc.
