 set save-silently to t can not avoid messages when saving files
Date: Mon, 16 Jan 2023 21:46:24 +0800

Hi Emacs dev team,

I tried to set save-silently to t, but the saving file message will
still show on echo area, but it disappear immediately.

Steps to reproduce:

1. emacs -Q to launch Emacs
2. eval (setq save-silently t)
3. C-x, C-f open any file and edit the file
4. C-x, C-s save the file
   Now you will see the message showing in the echo area in a short time

This is macOS specific, I think, due to differences in how redisplay
works on darwin.  I don't see this on GNU/Linux and on MS-Windows.  So
it looks like the implementation does what it's supposed to do, and
unless someone has ideas how to improve the result on macOS, I think
we should close this bug as wontfix.

Hi Eli,

You are right, it macOS specific, I also can't reproduce it on Windows
10 with Emacs 29.

To do the same, in Emacs 29 it's possible to add all these strings
like "Saving file..." to 'inhibit-message-regexps'.

Hi Juri,

Thanks for your advice.

I tried to set (setq inhibit-message-regexps "^Saving"), but the message
in acho area still exist when saving file.

@Eli, I aslo tried Emacs 28.2, (setq save-silently t) works as
expected.

The display code was significantly changed between those two versions,
for reasons much more important than this minor annoyance.  I guess a
side effect of those changes is what you see.

Please also customize 'set-message-functions' so that its first element
is 'inhibit-message'.  Also 'inhibit-message-regexps' should be a list.
These settings should disable the message:

  (setq inhibit-message-regexps '("^Saving"))
  (setq set-message-functions '(inhibit-message))

For the peoples who like to use auto-save-visited-mode with 1s interval,
this minor annoyance will become major annoyance.

Hope someone expertise on ns port can fix this issue in Emacs 29 or 30.


My use case is auto-save files with every second of idle time:

```
(setq auto-save-default nil)
(setq create-lockfiles nil)
(setq make-backup-files nil)
(setq auto-save-visited-interval 1)
(auto-save-visited-mode 1)
```

Or, is there any workaround to suspress the message when saving file?

Great, this setting works as expected:

```
(setq inhibit-message-regexps '("^Saving" "^Wrote"))
(setq set-message-functions '(inhibit-message))
```

Sorry, I pushed it without documentation, then later you added +++
and I forgot that it is not documented.
