Dear emacs-devel list,
I understand that launching emacs from the Terminal commandline will
give me the correct **environment variables**. Is anyone working on a
fix so that it can be launched from the dock?
However, even launching from the commandline doesn't give me the
correct **groups**. Does anyone have a fix for that?
Regards,
Rob

I think the problem is not fixable by Emacs, it's a generic conceptual
Mac OS X issue. When you launch Emacs from the Dock, no command-line
shell is ever involved, so none of the command-line shell init files
is ever evaluated.
You can set environment variables for the Finder and the Dock in
~/.MacOSX/environment.plist, see
<http://developer.apple.com/qa/qa2001/qa1067.html>. These will than
be inherited by Emacs. These settings are static, this file is not
using any kind of scripting language.
I would assume that you can write an AppleScript to do more dynamic
stuff. The script would talk to the Finder and/or Dock. You would
than add that AppleScript to your Startup Items (see the "Accounts"
System Preferences).
You can also set environment variables in your ~/.emacs using the
(setenv) function. This will than of course only affect packages that
get loaded afterwards.

Can you expand? I don't quite understand what you mean here.

Benny,
Thanks a lot! These things I didn't know about.

By 'groups' I mean the list of groups returned by the /usr/bin/groups
command. The list returned when running this from a sub-emacs shell
didn't match that returned on the Terminal commandline.
I now realise you're not meant to use /usr/bin/open to launch emacs
from the commandline! Doing it the prescribed way--running
.../emacs/mac/Emacs.app/Contents/MacOS/Emacs--I DO NOW SEE THE CORRECT
GROUPS.
Cheers,
Rob (appreciative user of emacs on the mac)

I use the following in my .emacs (note: it needs my xml-parse.el
module, http://www.newartisans.com/johnw/Emacs/xml-parse.el):
(when (file-readable-p "~/.MacOSX/environment.plist")
(with-temp-buffer
(insert-file-contents "~/.MacOSX/environment.plist")
(let* ((dict (cdr (assoc "dict" (read-xml)))))
(while dict
(when (string= "key" (caar dict))
(setenv (car (cdr (car dict)))
(car (cdr (cadr dict))))
(message "Setting %s=%s" (car (cdr (car dict)))
(car (cdr (cadr dict)))))
(setq dict (cddr dict)))))
(setq exec-path nil)
(dolist (path (nreverse (split-string (getenv "PATH") ":")))
(add-to-list 'exec-path path)))

??
Why do you need this? My understanding is that
~/.MacOSX/environment.plist is read by the Finder and that the
variables are inherited automatically by Emacs.
The code should only have an effect, if you log in through SSH, where
the Finder isn't in the loop. But for that situation you can set the
variables in ~/.cshrc or ~/.bashrc or somewhere similar.
What am I missing?

I can't reproduce that, can you give a step-by-step recipe?

The "open" tool should work fine. If I do
$ open /Applications/Emacs.app
I get the same Emacs as when I launch it from Finder. I also get the
same groups. "open" is basically a packaged AppleScript to ask the
Finder to launch a document, I believe.

Actually I use that method only for debugging, not for normal
startup. It has some minor problems for everyday use.
