disable messaging in echo area

disable messaging in echo area

hi
I have a function that runs in background every 10 seconds (with
run-at-time). That function saves a file, and this causes a message to
be displayed in the echo-area. I want to disable this message...


there was already a thread about that :
http://lists.gnu.org/archive/html/help-gnu-emacs/2009-08/msg00374.html


But the pointed solutions don't work

(flet ((message (&rest args) nil))
   (message "test")
   (write-file file)
   )
- the "test" message is not displayed, but the "write file" is still
displayed!


(let (message-log-max)
  (write-file file)
  )
- no effect!

What does the message say?  If it says "Wrote /foo/bar", then you
cannot disable it from Lisp, currently: this message comes from the
write-region primitive on the C level, not from a call to Lisp-level
function `message'.  The message which precedes that, the one which
says "Saving file /foo/bar...", should be disabled by flet-binding
`message' to nil, I think.

No amount of fiddling with Lisp-level `message' facilities will be
ever able to do what you want.  I suggest to file a feature request
(with "M-x report-emacs-bug RET") asking for a variable that could be
bound to disable all messages, even those coming from the C level.

hi
the write-region with visit argument solved the problem!

Anyway I filled the bug report.

A more general solution might be to use with-temp-message.  This logs
to the *Messages* buffer but doesn't put anything in the echo area:

(defun write-foo ()
  (interactive)
  (with-temp-message ""
    (write-region (point-min) (point-max) "foo")))
