Or can I make it auto-save once before enabling auto-save > mode? Buffer not visiting file does not know where it should be saved. I am using and doing something similar like you, I use buffers without file names as additional scratch buffers. If Emacs session is over, those temporary buffers are over. And I like sometimes to invoke them in different mode, such as `sql-mode' or `emacs-lisp-mode'. Because they are not connected to files, they can't be saved so easily. (defvar rcd-temp-buffer-mode-history nil) (defvar rcd-temp-file-directory "~/tmp/") (defvar rcd-temp-buffer-name "RCD TEMPORARY BUFFER") (defvar rcd-temp-buffer-modes '(("adoc-mode" . "adoc") ("emacs-lisp-mode" . "el") ("lisp-mode" . ".lisp") ("markdown-mode" . ".md") ("org-mode" . "org") ("sql-mode" . "sql") ("fundamental-mode" . "txt") ("html-mode" . "html"))) (defun rcd-temp-buffer (&optional name mode) "Generate new temporary buffer." (interactive "p") (let* ((format (concat "*" rcd-temp-buffer-name "%s%s*")) (buffer (if name (format format ": " name) (format format "" "")))) (switch-to-buffer (generate-new-buffer buffer)) (if current-prefix-arg (let* ((mode (completing-read "Mode: " (map-keys rcd-temp-buffer-modes) nil t nil 'rcd-temp-buffer-mode-history))) (funcall (intern mode))) (funcall (intern (or mode "fundamental-mode")))))) and that function could be adopted to provide file names for buffers: (defun rcd-temp-buffer (&optional name mode) "Generate new temporary buffer." (interactive "p") (let* ((format (concat "*" rcd-temp-buffer-name "%s%s*")) (buffer (if name (format format ": " name) (format format "" ""))) (file-name (concat rcd-temp-file-directory (format-time-string "%Y-%m-%d-%H:%M:%S.txt")))) (switch-to-buffer (generate-new-buffer buffer)) (setq buffer-file-name file-name) (if current-prefix-arg (let* ((mode (completing-read "Mode: " (map-keys rcd-temp-buffer-modes) nil t nil 'rcd-temp-buffer-mode-history))) (funcall (intern mode))) (funcall (intern (or mode "fundamental-mode")))))) Now if I have `do-auto-save' those temporary buffers would be saved I guess. -- Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns In support of Richard M.
