Assume I have the file ~/Documents/bla.org. Now I open a buffer that visits the file ~/Documents/bla.org.

I check the value of the (buffer-local) variable buffer-auto-save-file-name, and it reads /home/berber/Documents/#bla.org#.

Now I run the following code:

(let ((save-files-directory (file-name-concat user-emacs-directory "auto-save")))
  (make-directory save-files-directory :parents)
  (setq auto-save-file-name-transforms
    `((".*" ,save-files-directory t))))

If I now open a buffer that visits the file ~/Documents/bla.org, the value of buffer-auto-save-file-name reads /home/berber/.config/emacs/#!home!berber!Documents!bla.org#. This is the wrong directory, obviously.

When I check the variable auto-save-file-name-transforms, I get ((".*" "~/.config/emacs/auto-save" t)), which sounds right, but as seen above, it doesn't do the right thing... Yes, the directory /home/berber/.config/emacs/auto-save exists, and yes, I have done this with emacs -Q.

What could my problem be?

I am using Emacs 28.2.

Make sure that the directory name contains a trailing /:

(let ((save-files-directory
          (file-name-concat user-emacs-directory
                               "auto-save/"))) ;;; <-- add trailing slash 
  (make-directory save-files-directory :parents)
  (setq auto-save-file-name-transforms
    `((".*" ,save-files-directory t))))

    I didn't investigate this (I just tried it and it worked), but it feels like a (small) bug to me. If I find some time, I'll see if I can get to the bottom of it and maybe submit a bug report. Commented Nov 13, 2023 at 17:26
