bug#1555: OSX Emacs.app not containing enough paths (emacs lisp fix included)

Emacs.app version 23.0.60 (9.0)
(getenv "PATH")
    => bare minimum (/usr/bin:/bin:/usr/sbin:/sbin)

exec-path
    => bare minimum but with /Applications/Emacs.app/Contents/MacOS/bin

OSX seems to keep paths in /etc/paths and files in /etc/paths.d, programs
launched from Terminal seem to pick this up but Emacs.app is not loaded from
terminal so the path is kinda small. the problem was interacting with other
programs via m-!, eshell, etc.

this seems to fix it, not sure if it's the right way tho.

(setenv "PATH"
        (let ((osx-path-files
               (append (mapcar (lambda (x) (concat "/etc/paths.d/" x))
                               (delete ".." (delete "." (directory-files
"/etc/paths.d"))))
                       '("/etc/paths")))
              (read-path-file
               (lambda (file)
                 (when (file-readable-p file)
                   (delete ""
                           (split-string (with-temp-buffer
(insert-file-contents file)
                                                           (buffer-substring
(point-min) (point-max)))
                                         "\n"))))))
          (mapconcat 'identity
                     (reverse (delete-dups (reverse
                                            (append (reduce 'append
                                                            (mapcar
read-path-file osx-path-files))
                                                    (split-string (getenv
"PATH") ":")))))
                     ":")))

Applications are not run from a login shell, so they don't inherit the  
same paths.  This is an old problem.
Your method of addressing this won't work with pre-10.5 versions of  
the OS.

The correct way is, IMHO, either leave it to the system to set the  
correct environment variables for the applications, or, as a  
convenience for users, start a login shell, print the environment and  
import it.  (I've been doing that in Aquamacs for a long time; the  
code is there if people want it.)

Hi,

Please see the section about "Grabbing environment variables" in the  
Emacs.app (Mac / GNUstep) section of the info manual.

(Closing bug.)
