Good day all,
Is there a way for emacsclient to ask the daemon to make a new frame
(as in window-manager-managed X GUI frame, not a terminal one) only if
there isn't one already running? Presumably by using "--eval" on the
commandline I guess, perhaps something like ( unless selected-frame
(make-frame) ) ( find-file "myfile.txt" ) ..?
When I am about to open a file (from the bash command line) I often
don't remember whether I have a frame open or not.. If there is one,
I would want the file to be automatically opened there, and otherwise
I would want a new frame to be automatically created.
Any hints appreciated.
Best regards
Hugo Heden

Have you invoked
emacsclient --help
Yes, in GNU Emacs 23.0.91 it can!

Yes, thanks Peter, I have, but this is not what I want to do:
"-c, --create-frame Create a new frame instead of trying to use the
current Emacs frame"
What I want is a command line option (or some hacky script ) to
automatically create a new frame only if there is no frame currently
open. If there is a frame already, that frame should automatically be
reused.

Do you mean a frame or an emacs session?
If it's an emacs session, last emacs allow the -a option of emacsclient
empty:
If no emacs process is found, start emacs --daemon and open an
emacsclient frame.

I think this is done via the DISPLAY environment variable in the
shell where you launch GNU Emacs as daemon. Without $DISPLAY set GNU
Emacs assumes that it will run as the "client" of some terminal
emulation (inside of it). When it's set, then it's clear advise to
launch as an X client. I presume that X11 is running when you log in.
So DISPLAY is available and set.

But the above portion of the emacsclient help message seems to mean
that emacsclient already does what you want by default. That's why
you need the -c option to override that default and create a new
frame even if one already exist.
Doesn't the default work for you? Perhaps you should report a bug,
then.

Thanks all! I have diffuculties explaining what I am looking for.
1) I already have a daemon running, so that is not the problem. (Yes,
the alternate-editor option is good for that)
2) The --create-frame option creates a new frame yes, but it does so
every time the option is used. And that is a problem for me :-) I want
max *one* frame open at any given time!
3) Ok ok -- I *could* use my brain to manually do this:
if( there-is-a-frame-currently-open )
open-the-file-*without*-the-[--create-frame]-option
else
open-the-file-*with*-the-[--create-frame]-option
endif
--that would achieve what I am looking for.
4) But that would be a little to much waste of brain power! My problem
is that I do not want to have to remeber whether I already have a
frame open or not. The if-statement above is just too much for me to
bare. So I would want to write a little script that *autoamtiaclly*
achieve the above logic..
The cleanest solution would be to always invoke emacsclient with an
--eval option, something like this:
emacsclient --eval "( unless( x-display-list ) make-frame ) "
or this:
emacsclient.emacs-snapshot --eval "(unless(x-display-list)(new-frame))"
-- but I can't figure out how to write that eval (neither of the above
will work)..
5) This is similar to how I use Firefox: When I click on a link in a
mail, that link opens in a new tab in a currently existing frame..
unless there isn't one, in which case a new frame is automatically
opened.
Hmm, is this clearer? Any ideas?
Best regards

Again, doesn't emacsclient behave _exactly_ like that by default?
That is, doesn't emacsclient create a frame if it does not exist, and
reuses it if it does exist? If not, perhaps you should submit a bug
report.

Just use 'emacsclient.emacs-snapshot <whatsoever>.' If this does not
behave as you wish, then you've found a potential bug. Before you
submit a report, check the place where you launched the daemon for
messages. Check also whether the daemon has DISPLAY set in its
process environment. *I* have some problems:
Warning (initialization): An error occurred while loading `/Users/
pete/.emacs':
Wrong type argument: number-or-marker-p, 85
Because initialisation did not finish, the server hasn't started and

Thanks all, I apologize for having been dense. I thought the whole
time that the behaviour I was seeing was to be expected. The first
time I invoke emacsclient it opens in a terminal, not in a
window-manager-managed GUI-frame. I have to manually create a
GUI-frame using --create-frame. Subsequent invocations of the client
does not need --create-frame however.
The daemon does not emit any error messages, and there seems to be no
problem with my DISPLAY settings. Removing my clunky ~/.emacs does
not help. Invoking the emacs daemon with -Q and/or -D does not help
either. Will investigate a bit more (not sure how though) and possibly
file a bug report.
Thanks again all!
Best regards

That seems to be the intended behavior
"If the Emacs process has no existing frame--which can happen if it
was started as a daemon--then Emacs opens a frame on the terminal
in which you called `emacsclient', as though you had used the `-t'
option."

This is not really clever: after I successfully compiled GNU Emacs
from CVS I launch it for testing from the elder Emacs' *shell* buffer
– this has to fail then!

I think it's because emacs --daemon should fail if a second emacs-server
process is found.
So if you launch the first emacs with emacs -Q (without server-start)
and then from it, emacsclient -c -a "", it should start a second emacs
process (emacs --daemon) with an emacsclient linked to it.
(not tested)

I won't do it this way, Thierry. Since I usually have more than one
Emacs running at the same time I tend to control server business
tightly.
Anyway, I hope this strange behaviour in daemon mode will be
corrected before GNU Emacs 23.1 is released. It's outside one's
imagination that an X client will open inside some terminal
emulation ... OTOH: a second X11 in my Terminal – I should go ahead
and patent this before some MS guy does!

A common mistake that people make when trying to design something

Thanks Johan, I won't have to file a bug report then. Unless there is
a huge consensus here that this behaviour should be changed?
I am not sure how to achieve what I want to do, but I think I can make
some clunky bash-script that does
emacsclient.emacs-snapshot -e "(x-display-list)"
to see the whether or not there is a emacs GUI-frame on the current $DISPLAY.

Below follows a bash-script that does what I want to do:
If there is no daemon running, one is started automatically. If the
user has *not* specified -nw, -t, -tty, -c or --create-frame, then the
script figures out whether there is a frame open on the current
$DISPLAY, and if not the script *adds* the option --create-frame to
the options before passing them on to the real emacsclient.
Best regards

I have fixed some limitations in the script. Mainly, the script can
now handle command line options containing spaces (typically --eval
options). I will maintain an updated version on
