I don't think there's a default way. This is one of the problem that pains me. But if you use ergoemacs http://code.google.com/p/ergoemacs/ it's fixed there.

When you use ergoemacs, you can create buffers by Ctrl+n, which calls new-empty-buffer. Then, in this buffer, if modified and not saved, when you try to close it or quit emacs, emacs will prompt you to save it. However, it does not fix when if you just use switch-to-buffer (C-x b) command to create a new buffer. Here's the relevant source code. Note the line (setq buffer-offer-save t). Feel free to use it. (defun new-empty-buffer () "Opens a new empty buffer." (interactive) (let ((buf (generate-new-buffer "untitled"))) (switch-to-buffer buf) (funcall (and initial-major-mode)) (setq buffer-offer-save t))) ;; note: emacs won't offer to save a buffer that's ;; not associated with a file, ;; even if buffer-modified-p is true. ;; One work around is to define your own my-kill-buffer function ;; that wraps around kill-buffer, and check on the buffer modification ;; status to offer save ;; This custome kill buffer is close-current-buffer.

(add-hook 'first-change-hook #'(lambda nil ;; set for all 'regular' buffers (unless (string-match "\\`[ *].*[*]\\'" (buffer-name)) (setq buffer-offer-save t)))) -ap ^ permalink raw reply [flat|nested] 6+ messages in thread
