Hi sednivo!

Look at the desktop package.
I use emacs from CVS and there are the functions
M-x desktop-save
M-x desktop-read

That functions allow to save the list of open files in a directory.

You can't, AFAIK.  A close approximation would be to save different
sessions in different directories.  Then, whenever you start Emacs
from a directory with a saved session, Emacs will restore the session
recorded in that directory.

Saving Emacs sessions

[Petteri Hintsanen]

Hello Emacs devs,

I try to set up per-directory sessions, that is, save separate
.emacs.desktop files to certain directories.

Last time I used these was many years ago, around Emacs 21 or so.  Back
then, if I recall correctly, it was enough to do M-x desktop-save RET
and Emacs would ask for the directory where to save the desktop.  And by
setting (desktop-save-mode 1) in the init file, Emacs would restore the
desktop in the startup directory, should one exist.

With Emacs 28 I assumed the behavior would be the same.  Also the manual
suggests this (chapter 44):

  "If you turn on ‘desktop-save-mode’ in your init file, then when Emacs
   starts, it looks for a saved desktop in the current directory.  (More
   precisely, it looks in the directories specified by ‘desktop-path’,
   and uses the first desktop it finds.)  Thus, you can have separate
   saved desktops in different directories, and the starting directory
   determines which one Emacs reloads."

But with the default configuration, .emacs.desktop is saved into
~/.emacs.d/, and Emacs does not look for a saved desktop in the current
directory at startup.

The reason seems to be that the default value for desktop-path is
("~/.emacs.d/" "~").  It used to have ".", but that was removed in
commit e76f0800d2.

Was there a specific reason for omitting "."?  If yes, I would suggest
to clarify the manual so that it does talk about "current" or "starting
directory" at all.



[After writing this I found out that the manual has been changed in the
current git master.  But I think the issue still persists, see e.g.
misc.texi:2746.]



Thanks,
Petteri

"M-x desktop-save" still asks in which directory to save the desktop,
so you can still have that feature.

Yes, see bug#10977.

I have desktop-path customized since long ago to start with ".", as I
use this feature a lot.  Suggest that you do the same.

Fixed, thanks.

Ok, I see.  I was wondering if it had more serious implications like
security (cf. having "." in $PATH).

Yes I did this already.  Now it works as before.

Thanks for clarification,
