Oh yes, thanks. I have tried solving it by associating the file to buffer and then disassociating, as that way `set-auto-mode' works. (switch-to-buffer buffer) (setq-local buffer-file-name filename-revised) (read-only-mode 0) (insert body) (goto-char 1) (set-auto-mode) (setq-local buffer-file-name nil) (read-only-mode 1) Now it seem not good idea to use it with `set-buffer-modified-p' (switch-to-buffer buffer) (setq-local buffer-file-name filename-revised) (read-only-mode 0) (insert body) (goto-char 1) (set-auto-mode) ;; (setq-local buffer-file-name nil) ;; TODO (set-buffer-modified-p nil) ;; TODO which one is better? (read-only-mode 1) as then if I wish to save the associated file but buffer is not modified, saving is not easy, as Emacs thinks it was already saved. It is solved. I will let it be associated to versioned file number, if user wish to save revision of a previous file, the associated file name is there and user may save it. Jean
