Start the emacs-server once...

Start the emacs-server once...

[Alex Bennee]

Hi,

I want to set-up emacs to start the server once per X sessions (and I
guess once per screen session once I get multi-tty working). However
there doesn't seem to be way to check in emacs if the server is
currently running.

So far the best I can come up with is having my start-up emacs with the
args:

emacs --eval (defvar this-is-the-master t)

And appropriate hackery in the .emacs. Is there a nicer way to deal with
this?

I don't know if it is nicer (I suspect it is similar)
but I use the following so that the invocation of emacs is not changed.

;; Use emacsclient/emacsserver
;;
;; Using code from Tassilo Horn so a server started on first emacs only
;; The code should remove the file when the server ends.
;; Sometimes the file remains (why?) so I explicitly invoke the removal
;; function from ~/bin/Xinitialize.
(defvar ajg-server-lock-file "~/.emacs.d/server.lock" "Emacs server lock file.")

(defun ajg-server-start ()
  (interactive)
  (shell-command (concat "touch " ajg-server-lock-file))
  (server-start)
  (message "Emacs Server started...")
  (setq frame-title-format '("Emacs (Server): %b <%f>")))

(if (and (not (file-exists-p ajg-server-lock-file))
         (not noninteractive))
    (ajg-server-start)
  (message "Emacs Server NOT started, because lockfile exists.")
  (setq frame-title-format
        '("Emacs: %b <%f>")))

(defun ajg-server-remove-lock-file ()
  (interactive)
  (when (boundp 'server-process)
    (shell-command (concat "rm " ajg-server-lock-file))))

;; Remove lock file when emacs server ends
(add-hook 'kill-emacs-hook
          'ajg-server-remove-lock-file)

You might be interested in the page on the emacswiki about this [1]. My
config is detailed on there (along with lots of other peoples'
solutions!).

The one thing that I use that I really like is a function called
delete-frame-ex, which is hopefully below

I bind this to C-x C-c, which means that you can call the "magic emacs"
command on a load of files, edit them in different frames and when you
hit C-x C-c, you don't kill something you were working on in a different
desktop. For me, this is at least as important as spawning the frames in
the first place!
