In LaTeX mode C-c C-c is bound to:
(TeX-command-master &optional OVERRIDE-CONFIRM)
Normally this interactive function runs a command, perhaps a LaTeX compilation, asking for confirmation.
In tex-buf.el it reads:
If a prefix argument OVERRIDE-CONFIRM is given, confirmation will depend on it being positive instead of the entry in `TeX-command-list'.
This is a bit cryptic for me and reading C-h v TeX-command-list didn't help.
How can I pass the prefix argument to "TeX-command-master" so that I avoid all the confirmation requests?
回答1:
Take a look at Emacs' documentation to find out about prefix arguments. In general, you can pass a command a prefix argument with C-u followed by a number. For one-digit numbers, you can also just type Meta followed by the digit. Thus to pass a positive prefix argument to TeX-command-master you could type:
M-1 C-c C-c
However, this will actually add another minibuffer confirmation, namely about the shell command to be used to compile the LaTeX source. Without the prefix argument, a command-dependent default is used for that.
If you want to avoid the question about the command to use, you can bind the undocumented variable TeX-command-force to "LaTeX" via:
(setq TeX-command-force "LaTeX")
However, this will have the downside that you're basically binding C-c C-c to the "latex" command, you cannot use any of the other commands such as "bibtex" or "view".
Other than that, LaTeX-mode does not allow for any customization of C-c C-c. Your best options are to either advise the function TeX-command-query or to bind C-c C-c to a wrapper function to set TeX-command-force dynamically. The latter would probably be the preferred option if you also want to auto-save the buffer.
回答2:
It seems that the mystery of the OVERRIDE-CONFIRM continues. In the meantime a fellow suggests that, if we are unable to manage TeX-command-master, we can simply rewrite it.
In my version, based on his, if the buffer is not modified, the external viewer is launched; if the buffer is modified the compiler is run. Everything with no confirmation for saving or running the given command.
(defun my-run-latex ()
(interactive)
(if (buffer-modified-p)
(progn
(setq TeX-save-query nil)
(TeX-save-document (TeX-master-file))
(TeX-command "LaTeX" 'TeX-master-file -1))
(TeX-view)))
Of course one can bind my-run-latex to whatever keybinding.
On the user's point of view this is a solution to my own question.
Do I click the close tag? Well, on the curious guy point of view I am still interested in understanding the mysterious TeX-command-master technicalities.
If someone should happen to know...
P.S.
Yes, TeX-save-query overrides the save-file request, also with TeX-command-master, that is C-c C-c. But you will still be asked to confirm the command action.
回答3:
Build & view
Again, this solution, instead of modifying the behaviour of the TeX-command-master, rewrites it. The rewritten version of the command, named build-view, follows a rather straightforward logic.
- If the LaTeX file buffer is not-modified, it runs the default viewer;
- If the buffer is dirty, it runs the default LaTeX compiler and, after the build, opens the output in the default viewer.
Here's the code:
(defun build-view ()
(interactive)
(if (buffer-modified-p)
(progn
(let ((TeX-save-query nil))
(TeX-save-document (TeX-master-file)))
(setq build-proc (TeX-command "LaTeX" 'TeX-master-file -1))
(set-process-sentinel build-proc 'build-sentinel))
(TeX-view)))
(defun build-sentinel (process event)
(if (string= event "finished\n")
(TeX-view)
(message "Errors! Check with C-`")))
You can now type M-x build-view and start the told build-view process or associate it with a new keybinding such as “F2”:
(add-hook 'LaTeX-mode-hook '(lambda () (local-set-key (kbd "<f2>") 'build-view)))
Note: As suggested by Tyler, TeX-save-query variable is changed locally, therefore the old C-c C-c/ TeX-command-master is unaffected and will keep asking confirmations.
Do edit this code to make it better or easier to read!

I puzzled over the OVERRIDE-CONFIRM bit for a while, and couldn't figure out how it was supposed to work. If you want to automatically run Latex on your file, without being bothered about saving it first, or confirming that you want latex (rather than view, bibtex etc), you could use a function like this:
(defun my-run-latex ()
(interactive)
(TeX-save-document (TeX-master-file))
(TeX-command "LaTeX" 'TeX-master-file -1))
Bind this to something handy, and you'll still have C-c C-c for when you want to use the default processing commands. You may want to modify the TeX-command line if "Latex" isn't the processor you want to call.
回答5:
If you are just looking to compile the latex source without a confirmation dialog, just add the following to your .emacs:
(setq TeX-command-force "")
You can then compile the source with C-c C-c and it won't ask to confirm. The only problem with this solution is that you can no longer change the command, but with most documents you won't want to. I might suggest that at the same time you can add this to your .emacs for even more flexibility, giving you a C-c C-c equivalent to the former behavior:
(define-key LaTeX-mode-map "\C-c\C-a"
;;; 'a' for ask, change to anything you want
(lambda (arg) (interactive "P")
(let ((TeX-command-force nil))
(TeX-command-master arg))))
You can then just work away at your document, do a C-x C-s, C-c C-c and then C-c C-v to see it. Like others have suggested you can also do the same for the save command and have it compile automatically on save, but some of my documents are in CVS and so I avoid putting hooks on that.

I think the gist of this question is "how do I quickly compile my TeX document from AUCTeX without all the key presses and confirmations?"
My answer to that is to use the latexmk command rather than trying to coerce AUCTeX to do it.
latexmk -pdf -pvc myfile.tex
latexmk will monitor the file in question and rebuilt it as soon as you save it. If you use a good pdf viewer, it will notice the change in PDF and re-display it immediately. On OS X, skim works well for this.
