emacsclient command line use existing client

emacsclient command line use existing client

[Tory S. Anderson]

The following are part of a .so file I use to let browser mailto: links open a message in Gnus. 

elisp_expr="(mailto-compose-mail \"$mailto\")"

emacsclient -a "" -c -n --eval "$elisp_expr" \
	'(set-window-dedicated-p (selected-window) t)'

But somehow when I run this it starts a new emacsclient rather than using the one I have running. If I remove the `-a ""` then nothing happens at all. Why won't it connect to my existing emacsclient?

What exactly do you mean with "existing emacsclient"?  You must have a
running server.  A running Emacs is not enough.

Not sure what OP means, but I would like something similar too:

Having one emacs server running with possibly many emacsclients
connected, address one specific emacsclient from a program. 

Say I have a tmux window with 3 tiles, one of them the PicoLisp REPL,
another an emacsclient window showing an emacs-w3m buffer. Now I want a
PicoLisp command that calls emacs to show symbol documentation in
emacs-w3m (instead of standalone w3m, which is easy to achieve). 

But there are several tmux windows opwn, and more emacsclients
connected. How do I tell the emacs-server on the command-line to reuse
that one specific emacsclient instance side-by-side with the PicoLisp
REPL?

cheers,
Thorsten

Re: emacsclient command line use existing client

[Tory S. Anderson]

Thanks for prompting me to be more precise. When my OS starts I launch a server with the autostart `emacs-client` command, and have the line in my .emacs to ensure the server is started. As it should, opening any number of new frames (or launching emacs-client again) will share the same buffer list, etc. However, this shell script for launching an email (apparently) starts a new server; it isn't sharing anything with the other frames, and if I don't `kill-emacs` I end up with two servers running. Clearly, not acceptable.

Hello,

my guess: emacsclient inside your script runs another installed
instance of emacs as you started emacs server with. With option -a ""
this instance will start another emacs in deamon mode. Probably the
$PATH while runing the mailto-script is different.

Check your OS "autostart `emacs-client` command" - as you mentioned -
and make sure your script uses the emacsclient from the same ./bin
directory. 

  Greetings, Oliver

Re: emacsclient command line use existing client

[Tory S. Anderson]

Yeah, the problem is starting a new server every time. But all these commands just run `emacs-client`. I've even ditched the auto-start one and just execute a later emacs-client. I've added server names and specifications to each command. I now have: 

in .emacs:
----------
(require 'server)
(setq server-name "my-emacs-server")
(unless (server-running-p)
    (server-start))


in email.so:
----------
mailto=$1
mailto="mailto:${mailto#mailto:}"
mailto=$(printf '%s\n' "$mailto" | sed -e 's/[\"]/\\&/g')
emacs_server="my-emacs-server"
elisp_expr="(mailto-compose-mail \"$mailto\")"
emacsclient -a "" -c -n -s "$emacs_server" --eval "$elisp_expr" \
	'(set-window-dedicated-p (selected-window) t)'


my shortcut for opening emacs (which DOES open under the proper server)
---------
emacsclient -c -s "my-emacs-server"


And still clicking a @mailto: link (running email.so) starts a new, unattached server.

That this doesn't work could be due to bug#13319, "emacsclient doesn't
find server with nonstandard name".

Re: emacsclient command line use existing client

[Oliver Kappel]

In email.so try to set the absolute path for emacsclient.

/usr/local/bin/emacsclient  or whatever fits your environment. We
don't even know on what OS you are. `emacs-client` is unknown to me
and script extension .so is uncommon too.

I'm still not convinced your script is starting the right emacsclient,
as your shell/shortcut does.

Re: emacsclient command line use existing client

[Tory S. Anderson]

*sigh* still no go. I've put the full path in the calls everywhere, and I've named the server "server" instead of "emacs-client" (you were right; that was one problem). When I use a shortcut that calls just the "emacs-client -c" it opens, attached to "server" (with all the same buffers still available). When I go to the start menu and find "emacs client", it is also working appropriately. However, when I hit ~/email.so from my Firefox, it launches a new server. Adding the fully qualified path, and/or "-s server" doesn't change this. 

$ whereis emacsclient
emacsclient: /usr/bin/emacsclient /usr/share/man/man1/emacsclient.1.gz

I have only one location. Is there some reason that .so script (I could just as well rename it to .sh) is opening it as a new server?

^^^^^^
This line is your most obvious potential point of failure.  Have you checked your running script to make sure that your variable expansion is proper?
IE Is -s "$emacs_server" actually expanding to "server" and not say ""server"" or something obnoxious like that? 
Try hard-coding the call line to -s "server" and see what happens.

[Tory S. Anderson]

Ok. I did the following tests:

- Tried your script. From Firefox, it doesn't seem to run at all. From the command-line, it opens TWO emacs windows, one in a blank  "server" buffer and another with the email I want. Both are connected to the correct server, though. 
- My old script (as listed below) does exactly what it should from the command line; it's, apparently, just from Mozilla that it creates a new server.

Did you set "network.protocol-handler.app.mailto" in "about:config" in
Firefox to the script? It works for me.

Your are right. Something is screwy in message-mode. This didn't use to
happen (no server buffer).

Strange, setting "Firefox Preferences -> Applications -> mailto:" should
set "network.protocal-handler.app.mailto".[1]

Maybe you can try adding it manually in "about:config". Right click on

Re: emacsclient command line use existing client

[Tory S. Anderson]

Yeah, I created network.protocal-handler.app.mailto manually but it still doesn't change things; it starts a new server.

RE: emacsclient command line use existing client

[Subhan Michael Tindall]

Are you setting the name of the server in your startup script? Maybe this option will help:

'-s server-name'
'--socket-name=server-name'
Connect to the Emacs server named server-name. The server name is given by the variable server-name on the Emacs server. If this option is omitted, emacsclient connects to the first server it finds. (This option is not supported on MS-Windows.)

That sounds like you might be starting 2 servers.

Not sure what you mean there.  What line in .emacs? Does it start a
second server in addition to the one started when OS starts?

In your script you need to say which emacsclient server to attache to.

something like `emacsclient -s SERVERNAME -c' (or what ever other flags
you use)

Will only attache to SERVERNAME
