Gnuserv vs Emacsserver

Gnuserv vs Emacsserver

[Magnus Berg]

Hi!

I'm little confused about the possibilities with Emacsserver in Emacs 23 
(cvs). I had used Gnuserv before because it makes it possible to open a 
new buffers/files, from the filemanager etc, in the initial frame (whith 
dtemacs).  I don't want to have my screen cluttered with frames.
Now I wonder if it's possible to do the same with Emacs 23:s Emacsserver 
or if I should continue to use Gnuserver for that. If it's possible with 
Emacsserver, can you tell me how.

No, there was nothing about opening new buffers/files in the initial frame.

Sorry, you are right. Look at the option server-window in Emacs. (I am
surprised it is not mentioned.) Does that help you?

No! :-) I have read quite a lot about emacsserver. (I got the "GNU Emacs 
manual" as a book and it covers version 22) I have searched and looked 
up the options but I don't get a grip of it. I found a option for 
emacsserver there I can set the variable "server-window" to a window or 
a frame. And it is by default set to "Use selected window" and it is 
possible to chose "Display in new frame", "Use pop-to-buffer" and "Other 
function". I suppose the last alternative could include some smart 
setting for the ones who knows lisp or what to do. But I don't.

But I'm not sitting here crying :-) I installed Gnuserv and it does what 
I want. But it should be fun to now how to do it without extra lisp 
packages, if it is possible with the included emacsserver.

Thanks for your interest in my question Lennart!

But can you then please explain what you want to do then? I thought
you wanted to open a file in a specific Emacs frame. Is not that what
you want to do?

I have wondered about swithing to emacsserver for some time. I have
been using gnuclient for a long time (on W32). Changing over to
emacsserver became a possibility with emacs 22, but I haven't yet done
it.

For my style of working, I find there are irritations in switching
over. I wonder if anybody has any solution.

1. My version of gnuclient starts emacs (if it can find it) if it
cannot connect to a running instance. I could, of course, make sure it
is running before I use it.

2. Irrespective of whether I am running emacs 21 or 22, it can still
connect.

3. The biggest irritant is that if I start another instance of emacs,
either by mistake or because I want to do something in a console
window, it clobbers my previous instance. With gnuserve, it fails with
a dialog box, which is also irritating, but it works the way I want
it. Ideally I would not like to keep changing the commandline, but I
don't see how I would do it even with that.

4. I need to change too many places in the system registry where it
invokes gnuclient. I can perhaps do that if I can handle the others.

I believe "emacsclient -a" can do that, too.

Do you really need to run Emacs 21 from time to time?

You can arrange for it to not do that in your .emacs: just don't start
the server if there's evidence that one other instance is already up
and running.

You could have a script called gnuclient.cmd that just invoked
emacsclient.

I don't know about the OP, but I *definitely* need to run Emacs 21, due to
problems editing remote files with tramp/ange-ftp under Emacs 22 (as I've
posted previously).

Yes!
But the defult "Use selected window" in the the variable "server-window" 
doesn't, even if it maybe should. And I had the argument 
(server-start) in my .emacs As I understand it that should run Emacs as 
Emacsserver. And I choose to open new files, from the filemanager with 
the application/command emacsclient. But all opened files creates a new 
frame.

After looking at the suggestions, I have tried to work on my most
irritant point 3.

Here is a package that does what I want.

Now the next is to try item 4. Looks like creating an executable that
handles the same arguments but uses emacsserver is the simplest.
I will try to do that for me.
