Emacs server

Emacs server

[Thorsten]

Hello list, 
I try to run emacs24 as a server on ArchLinux, and it works with M-x
server-start inside a runnung emacs. When I start emacs with --daemon, I
receive the message that the daemon is started, and I see how the
load-files are loaded, and finally control is given back to the shell
process. However, emacsclient does not find a socket, and top doesn't
show an emacs process running. 


Here are my start scripts: 

daemon: 
,-----------------------------------------------------------------------
| #!/bin/sh                                                             
| exec emacs --daemon=emacs1  -l  ~/.emacs.d/emacs24-starter-kit/init.el
`-----------------------------------------------------------------------

client: 
,---------------------
| #!/bin/sh
| exec emacsclient  -c
`---------------------

What might be the problem?
cheers

Change server to "emacs --daemon -l ..." or
client to "emacsclient -s emacs1 -c ..."
(not both, exclusive or ;)

Thank, that does the job. One more related question: I like to have a
black background and white (or wheat) foreground (and I'm not such a fan
of the color-themes because of their generally weak contrasts). In an X
session, I would start emacs with -fg black and -bg wheat flags. In an
console session, this looks strange, but starting emacs without those
two flags already gives a black background and a white foreground.

Now - what can I do when I want to have only one emacs-server running
and start several emacsclients in the console as well as in the X
session? Is there a way to start different emacsclients with different
fg/bg colors without always changing the colors explicitly with M-x
set-{background, foreground}-color when switching between the clients?

Perhaps the variables `server-visit-hook' and `window-system can help'.

That sounds very promising - thanks again for your help.

'window-system seems to be deprecated in favor of 'display-graphic-p, no
problem. But where are the server hooks gone? I find references to
several server hooks on the web, but my emacs24 only returns one server
variable:

,------------
| server-mode
`------------


I used M-x apropo to look for a hooks - but no server-hooks among the
thousands of hooks. 
Do I miss something, or are they simply gone? The `server-visit-hook
would serve me perfectly to solve my problem.

I missed something essential - the server hooks only show up in the
system, when a server is running. 
Sorry for the noise ...

Does emacsclient handle the -name argument?  If so, you can set up different
foreground/background pairs in ~/.Xdefaults with different instance names.

Yes 
"The emacsclient program can specify a server by name, using the -s
option"
Since I want only one server instance running, you mean I could define
alias-names that point to the same server, but set up different fg/bg
colors? 
I would not know how to do this. 

I already solved the color-problem using the server-visit-hook and
display-graphic-p predicate. 

I still have some problems to gracefully exit my "1 server, many
(terminal and X11) clients" setup. When I use 'C-x #' to close unused
emacsclients in the X11 and return to my terminal session, all my
emacsclients there are killed too - very inconvenient. And when I
finally kill the emacs-daemon with 'M-x kill-emacs', I'm asked at the
next start-up if I want to recover the crashed session. But I don't want
to crash emacs on exit, I want to shut it down in a controlled and
civilized manner.
