how can tell emacs not to load desktop when invoked by mutt?

[wang yin]

Hi,

I set my mutt's editor variable to "emacs -nw" :)
But I use the "desktop package". So every time I reply a mail, emacs
will start over again and load ~/.emacs

I have desktop sessions saved with the desktop package.
And loading the session is slow. I don't want these lines to be
executed from time to time when I reply or compose mail:


(load "desktop") 
(desktop-load-default) 
(desktop-read)


But I'm new to Emacs, and I don't know how to tell emacs it's invoked
by mutt. The hint to emacs, I think it that it's file name is
/tmp/mutt-myloginname-date.

Can anyone give an example how to set a conditional? Thanks!

You rather want to look up "emacsclient" in th Emacs manual.

No. emacsclide will send the buffer to a emacs server. But I don't
want to switch to another window.

Or I misunderstood emacsclient?

That's not to say that "emacs --no-desktop" wouldn't be a useful thing.

Particularly when debugging problems which happen at start-up (which I
was doing last night), or when one wants "just" to edit a quick textfile.

In fact, this ability to start quickly is an excellent reason to use vim
or even notepad.

I think the other replies to this post (emacsclient) are good but
there was no direct answer to the question. Here is my proposal:

1. Run the `mutt' command through a script.
2. Add an environment variable MUTT=ON.
3. Wrap your desktop loading in ~/.emcas :
          
    (or (string-equal (or (getenv "MUTT") "-") "ON")
        (progn
           (load "desktop")
           (desktop-load-default)
           (desktop-read)))

Ehud.

True, I have the following for when I want a fast start and I don't
care what I was looking at last session

      ;; some cheating here ....
  (setq desktop-basefilename
	(convert-standard-filename ".emacs.desktop"))

  (if (and (file-exists-p (concat "~/" desktop-basefilename))
	   (yes-or-no-p "Load desktop? "))
      (progn
	(require 'desktop)
        ....
but that may be too much noise for some!

Can emacs somehow test the command it was invoked with

emacs -nw /tmp/mutt-...

contains the string mutt?

Re: how can tell emacs not to load desktop when invoked by mutt?

[wang yin]

Thank you! This is almost what I want!

Can you tell me how can I use regexp to match the file name that mutt
tell emacs to edit: /tmp/mutt-mylogin-date in elisp?

Then I can use the following elisp(in pseudo-code):

(or (regexp-match ("/tmp/mutt-[^-]+-[0-9-]+", file-name))
        (progn
           (load "desktop")
           (desktop-load-default)
           (desktop-read)))


If I got this done, the problem is solved perfectly :)

So please tell me how to program the predict:
(regexp-match ("/tmp/mutt-[^-]+-[0-9-]+", file-name))

Do you really need to be that precise about the mutt file name?
Surely "/tmp/mutt-" is good enough...

(unless
    (catch 'found
      (dolist (arg command-line-args)
        (if (string-match "^/tmp/mutt-" arg)
            (throw 'found t))))
  (load "desktop")
  (dekstop-load-default)
  (desktop-read))

How about another approach entirely?  You start Emacs, then say M-x
server-start RET, and you configure mutt to invoke emacsclient
instead of emacs.

I've tried that before and the problem is the focus.  I was able to
make emacsclient rise up and take the focus but when finishing the
e-mail and closing the buffer, the focus does not return to the Mutt
window.

Maybe it works if you tell Emacs to open a new frame for each
connection.

You'd want to create the frame from server-switch-hook or
server-visit-hook, and you'd want to delete the frame again from
server-done-hook.
