emacsclientw not working

emacsclientw not working

[Ted Dennison]

I'm running on Window XP, and recently upgraded to emacs 22.1. I
downloaded the binary edition from ftp://ftp.gnu.org/gnu/emacs/windows/
.  I made extensive use of gnuclientw in the past, and am now trying
to switch over to emacsclientw. I'm not having much luck.

I put (server-start) at the top of my .emacs, and it appears to be
starting correctly. The only message I see in messages is:
Loading server...done

However, when I run emacsclientw on a file, I get the following:
---------
emacsclient: No socket or alternate editor.  Please use:

        --server-file      (or environment variable EMACS_SERVER_FILE)
        --alternate-editor (or environment variable ALTERNATE_EDITOR)
---------

I can of course add "-a emacs", but that just starts a new emacs for
every file (even if I leave the first one up).

Does anyone have any idea what I may be doing wrong here?

server.el creates a file with information that emacsclient needs. By
default that place is ~/.emacs.d/server and the file name is "server"
(both can be modified).

Try doing:

 C:\> SET EMACS_SERVER_FILE=%HOME%\.emacs.d\server\server
 C:\> emacsclient MY_FILE

or

 C:\> emacsclient --server-file=%HOME%\.emacs.d\server\server MY_FILE

(with %HOME% pointing to Emacs' home dir, of course).

Since that is what Emacs does by default, the most likely cause of
problems is that emacsclient's idea of HOME differs from Emacs. This
is likely from a bash shell, where HOME will be set up for Cygwin
programs. I'm not sure what emacsclient does when HOME is not set, but
that could be another source of problems.

I have no %HOME% variable, but I did it with C:\.emacs.d\server
\server  (C: seems to be where emacs thinks "~" is when I start it
up), and that did the trick. Thanks!

I guess that info was right in the error message. I just had no clue
what --server-file was, or how to use it.

I'm trying this from a cmd.exe shell, and have no %HOME% env variable,
so I'm guessing the issue is the latter.

I did run the addpm.exe from emacs's bin directory, but I guess it
didn't set this up.

I just tried setting it locally in my command shell, and now it works
without needing the --server-file argument.

On Windows XP (which the OP is using), when HOME is not set Emacs
defaults to %APPDATA%, as does emacsclient.c.

To be precise, the Emacs code (which is yours) use

  get_folder_path (NULL, CSIDL_APPDATA, NULL, 0, default_home);

while the less sofisticate emacsclient code does:

  getenv ("APPDATA")

but the results should match.

What I don't understand is why Ted's Emacs thinks that HOME points to
C:\. Emacs 22.1 running on XP should default to "C:\Documents and
Settings\User\Application Data" or somesuch.

What is the value of the registry key HKLM\SOFTWARE\Gnu\Emacs\HOME (if any)?
