emacs daemon.. but quietly

emacs daemon.. but quietly

[Gary .]

Is there any way to stop emacs, run with --daemon, printing out
details about all of the config files it is loading? At the moment I
see
  ("emacs" "--quiet")
  Loading charset...
  Loading charset...done
(etc.) which is ugly since I want to start the server, when
appropriate, when I start my login shell by doing something like

  function serverExists {
    TMPDIR=${TMPDIR-/tmp};
    TMPFILE="${TMPDIR}/ps-output.$$";

    ps > ${TMPFILE}
    grep -q 'emacs-X11' ${TMPFILE}
    SERVER_STARTED=$?;
    rm ${TMPFILE}

    return $SERVER_STARTED;
  }

  if serverExists ; then
   export EMACS_SERVER="emacs already started"
  else
   emacs --daemon --quiet
   export EMACS_SERVER="emacs started here"
  fi
  echo $EMACS_SERVER

in my .bashrc.

Any ideas, anyone?

If I understand you correctly, you want to suppress stdout/stderr output
of emacs --daemon?

You might just redirect that to /dev/null like so:

  emacs --daemon > /dev/null 2>&1

(or did I misunderstand you completely?)

Hm. I don't quite understand this part. Besides, it seems a roundabout
way. What are you trying to achieve?

As is emacs --daemon IMO.

In emacs 23 using the alternate editor setting. My "edit" script is:-

,----
| #!/bin/bash
| # edit
| export GDK_NATIVE_WINDOWS=1
| exec emacsclient --alternate-editor="" -c "$@"
`----

Its in the man page for emacsclient and the wiki.

Oops.

Oops, oops, oops.

I completely missed that. How embarrassing.

Thanks for the "hint". In my defence, who would want a different editor :-D

Heh, it's easily missed but very handy to know!

No, you understand perfectly. I'm pretty sure I tried that already,
but will try again. Thanks.

I was right, I had tried this, or something like it, and it didn't work,
at least not perfectly. It might be that I forgot to do the "2>&1", I'm
not sure, but anyway your way works just fine. It doesn't work if I try
it with the emacsclient --alternate-editor "trick", I just get dumped
back to the command line instead of it starting any kind of emacs. I
guess I will have to decide between the two methods. I'm leaning towards
mine (yours and mine), because it means there is never a delay when
starting emacs, which is somehow gratifying (I find a delay when
starting the first bash session of the day acceptable, although in fact
I might even try
 emacs --daemon > /dev/null 2>&1 &
meaning I might not even see that)

You could redirect the output of the command to /dev/null (if you're
using Linux or similar).

Why is the output a problem?  How do you "login"?

PS: You could avoid starting this daemon eagerly and do it lazily using
the "-a ''" parameter.  BTW your `serverExists' could instead do
"emacsclient --eval 1".
