I usually setup a nontrivial compile command, then frequently call 'recompile
. Is there a way to suppress the prompt for saving files similar to the approach in auctex invoked with (setq TeX-save-query nil)
? I find it very annoying to always have to save manually, or press y
at the prompt. When I hit recompile, I want all files saved if necessary.

compilation-ask-about-save is a variable defined in `compile.el'.
Its value is t
Documentation:
Non-nil means M-x compile asks which buffers to save before compiling.
Otherwise, it saves all modified buffers without asking.
You can customize this variable.
Here is the function recompile
, which demonstrates that it also uses the variable compilation-ask-about-save
:
(defun recompile (&optional edit-command)
"Re-compile the program including the current buffer.
If this is run in a Compilation mode buffer, re-use the arguments from the
original use. Otherwise, recompile using `compile-command'.
If the optional argument `edit-command' is non-nil, the command can be edited."
(interactive "P")
(save-some-buffers (not compilation-ask-about-save)
compilation-save-buffers-predicate)
(let ((default-directory (or compilation-directory default-directory))
(command (eval compile-command)))
(when edit-command
(setq command (compilation-read-command (or (car compilation-arguments)
command)))
(if compilation-arguments (setcar compilation-arguments command)))
(apply 'compilation-start (or compilation-arguments (list command)))))
See also the doc-string for save-some-buffers
-- "Optional argument (the prefix) non-nil means save all with no questions."
save-some-buffers is an interactive compiled Lisp function in
`files.el'.
It is bound to C-x s.
(save-some-buffers &optional ARG PRED)
Save some modified file-visiting buffers. Asks user about each one.
You can answer `y' to save, `n' not to save, `C-r' to look at the
buffer in question with `view-buffer' before deciding or `d' to
view the differences using `diff-buffer-with-file'.
This command first saves any buffers where `buffer-save-without-query' is
non-nil, without asking.
Optional argument (the prefix) non-nil means save all with no questions.
Optional second argument PRED determines which buffers are considered:
If PRED is nil, all the file-visiting buffers are considered.
If PRED is t, then certain non-file buffers will also be considered.
If PRED is a zero-argument function, it indicates for each buffer whether
to consider it or not when called with that buffer current.
See `save-some-buffers-action-alist' if you want to
change the additional actions you can take on files.

For the impatient: I put
(setq compilation-ask-about-save nil)
into my.emacs
and it works. Aug 20, 2014 at 9:08
