bug#4237: 23.1; --script prints loading messages

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:


I wrote a script in elisp that I run with "emacs --script".
It prints a lot of stuff before the script even starts:

Loading /usr/share/emacs/site-lisp/site-start.d/bbdb-mode-init.el (source)...
Loading /usr/share/emacs/site-lisp/site-start.d/focus-init.el (source)...

Loading /usr/share/emacs/site-lisp/site-start.d/vm-mode-init.el (source)...
Loading /usr/share/emacs/site-lisp/site-start.d/w3m-init.el (source)...


I think that --script would be nicer if, by default, messages emanating
from Emacs were suppressed; only messages from my script should be
emitted.

For debugging purposes a --verbose flag or the like might help.


If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/share/emacs/23.1/etc/DEBUG for instructions.

bug#4237: 23.1; --script prints loading messages

[Aaron S. Hawley]

I'm not an Emacs developer, but want to make a few comments.

I think Emacs does a pretty good job of keeping quiet.  I can
understand the frustration.  Especially because I have used Fedora and
seen the same messages.  When I've needed to use --batch (same as
--script), I would simply add the -Q or -q options to avoid seeing
such messages.  This had the potential secondary benefit of optimizing
the startup time for the Emacs batch process I was working on, as
well.

Perhaps, Emacs could be changed to mute messages that are part of the
site file or the init file when the --script option is used -- which
is the actual request.

But perhaps people interested in writing Emacs Lisp scripts should be
told to be especially careful to keep their site and user init files
quiet.

For example, the site-run-file file included with Emacs for Fedora
GNU/Linux  could be fixed:

--- site-start.el	09 Sep 2004 00:37:38 -0400	1.9
