how to make (TeX-command-run-all) save automatically without asking?

Question

I have just upgraded to AUCTeX 11.89.1 in emacs and find the new command (TeX-command-run-all) quite convenient. One problem is that after modifying the file and typing C-c C-a, confirmation is needed to save the file first.

I suspect that I kind of only need to set something to nil to deactivate this confirmation step, but I have not found a way. Any suggestions? Many thanks!

Answer 1

The variable TeX-save-query controls this behavior:

User Option: TeX-save-query

If non-nil, then query the user before saving each file with TeX-save-document.

Add the following line to your init file

(setq TeX-save-query nil)

Answer 2

There is a lisp package, auto-save-buffers.el

Put into your .emacs:

(require 'auto-save-buffers)
(run-with-idle-timer 2 t 'auto-save-buffers)
(global-set-key [f8] 'auto-save-buffers-toggle)

»2«: seconds between stop typing and saving

»f8« toggle the function.

Another approach would be to automatically save the buffer before evaluating TeX-command-run-all. The below simply adds a (save-buffer) prior to doing everything that the original TeX-command-run-all does, and then binds the new command over the original interactive key sequence.

(defun save-and-TeX-command-run-all (arg)
  (interactive "P")
  (save-buffer)
  (cond
   ((null arg)       (TeX-command-sequence t t))
   ((= 4 (car arg))  (TeX-command-run-all-region))
   (t                (LaTeX-command-run-all-section))))

(define-key LaTeX-mode-map (kbd "C-c C-a") 'save-and-TeX-command-run-all)
