Start emacs without opening a window (X11)

Start emacs without opening a window (X11)

[Sebastian Kaps]

Hi!

Is there a possibility to start Emacs without opening a window?
I want to start the Emacs server from my .emacs and then use only
emacsclient to pop up a new window.
XEmacs knows an option "-unmapped" which does exactly what I want, but I
haven't found anything similar in Emacs.

No, not quite. It starts emacs inside the terminal window it has been
called from and all emacsclient buffers open within this instance.

If you use the current development version of emacs which includes
multi-tty, then you can use these two scripts.

--8<---------------cut here---------------start------------->8---
#!/bin/bash
#
# Usage: emacs-preload <name> [<waitp>]
#
# Preloads the Emacs instance called NAME in a detached screen session.  Does
# nothing if the instance is already running.  If WAITP is non-empty, the
# function waits until the server starts up and creates its socket; otherwise
# it returns immediately.

name="$1"
waitp="$2"
screendir="/var/run/screen/S-$USER"
serverdir="/tmp/emacs$UID"
emacs=/usr/bin/emacs

if [ -z "$name" ]; then 
    echo "Usage: preload_emacs <name> [<waitp>]" >&2
    exit 1
fi

if [ ! -e "$screendir"/*."$name" ]; then
    if [ -e "$serverdir/$name" ]; then
        # Delete leftover socket (for the wait option)
        rm "$serverdir/$name"
    fi
    screen -d -m -S "$name" "$emacs" -nw --eval "(setq server-name \"$name\")" --funcall server-start
fi

if [ ! -z "$waitp" ]; then
    while [ ! -e "$serverdir/$name" ]; do
        sleep 1;
    done
fi
--8<---------------cut here---------------end--------------->8---

--8<---------------cut here---------------start------------->8---
#!/bin/bash
# Usage: connect-emacs <name> <args>...
#
# Connects to the Emacs instance called NAME.  Starts up the instance if it is
# not already running.  The rest of the arguments are passed to emacsclient.

name="$1"
shift

if [ -z "$name" ]; then
    echo "Usage: connect_emacs <name> <args>..." >&2
    exit 1
fi

# Startup that emacs if it's not running!
emacs-preload "$name" wait

/usr/bin/emacsclient -s "$name" "$@"
--8<---------------cut here---------------end--------------->8---

I'm using v22.1 and your scripts don't seem to work with that version.

Indeed, they're for Emacsen >= 23.0.50 only.  But now enjoy pleasant
anticipation for the 23.1 release. :-)

Use "-iconic", and don't have a specified icon.

I'm using Gnome, so I can't hide the window that way. Also, for some
reason, -iconic or --iconic has no effect here.

Well...  go back one step, to where you mention XEmacs
and -unmapped, and use that!

What do you mean? Does emacs now support a -unmapped parameter on startup?

I mean the obvious, use something that does support -unmapped!

XEmacs.

It seems that there's no other way than to launch emacs -nw in a
screen(1) and forget about it.  Since Emacs has become a true server, it
may be a good idea to had a `-daemon' option or something like that.

Any opinion?

It would be great to be able to do this. Karoly said on this list that
the way to implement this is to implement a special kind of display
that does not output anything.

We just need someone that is interested to work on this...

Basically, it'd be like -batch except without the `noninteractive' and
such stuff.
