Hi there,
as part of a function of mine, I want to save a buffer. However, I do
not want any messages logged (as save-buffer does). I found this in the
manual:
--8<---------------cut here---------------start------------->8---
You can write the contents of a buffer, or part of a buffer, directly to
a file on disk using the ‘append-to-file’ and ‘write-region’ functions.
Don’t use these functions to write to files that are being visited; that
could cause confusion in the mechanisms for visiting.
--8<---------------cut here---------------end--------------->8---
Why shouldn't I use `write-region'?
Best,

If you do something like:
#+BEGIN_SRC emacs-lisp
(let (message-log-max)
...
(save-buffer)
...
)
#+END_SRC
then message-log-max is nil while save-buffer is executed and so
it doesn't log the message.

Because find-file doesn't necessarily put the file contents in the
buffer, but some "formatted" or "extracted" version of if.
You may try basic-save-buffer
which writes a message only if no save was needed.

Thanks, that's /almost/ it - but it still shows the message in the echo
area... How to avoid that?

#+BEGIN_SRC emacs-lisp
(let ((inhibit-message t)
message-log-max)

(save-buffer)

)
#+END_SRC
