Carbon emacs (OSX) & /usr/bin/emacs using the same .emacs

Carbon emacs (OSX) & /usr/bin/emacs using the same .emacs

[jOHn wONg]

Hi all,

in my .emac file, I want to load different things onto different emacs
by a structure such as the followings:

(if (or (eq window-system 'w32) (eq window-system 'win32))
    (progn
     (print "we are in windows!")
     ;; making Emacs to work with Cygwin
     (setenv "PATH" (concat "C:/cygwin/bin;" (getenv "PATH")))
     (setq exec-path (cons "C:/cygwin/bin/" exec-path))
     (require 'setup-cygwin)
     ;; For subprocesses invoked via the shell
     ;; (e.g., "shell -c command")
     (setq shell-file-name explicit-shell-file-name)))

Of course the above is for detecting windows, is there any parameter
that can let me tell the difference between Carbon Emacs and /usr/bin/
emacs Emacs (in darwin shell)?

mac-carbon-version-string is present in Carbon Emacs, and /usr/bin/
emacs is lacking such a variable. However, I do not know how to make
use of this to write the .emacs file (evaluating mac-carbon-version-
string will give me a "void-variable" error in /usr/bin/emacs)

Please suggest! Thanks in advance.

The versions of both Emacsen are different. Emacs-major-version is 21  
for Apple's non-windowing version. The *function* emacs-version (you  
can save its output in a variable) tells quite a lot.

Yes, `window-system' is 'mac in Carbon Emacs.  In terminals it is nil.
In both `system-type' is 'darwin.

That depends on the OSX version.  10.5 has 22.1.1.

No, who told Apple that GNU Emacs was updated?! At least the  
*variable* emacs-version is 22.2 for Carbon Emacs. And as I  
mentioned, the function gives more details for distinction.

Hi,
I don't use Carbon, but you might be able to do something useful
with invocation-path, which contains the directory containing the
current emacs binary.
