A GNU Emacs library to setup environment variables from the user's shell.
On OS X, an Emacs instance started from the graphical user interface will have a
different environment than a shell in a terminal window, because OS X does not
run a shell during the login. Obviously this will lead to unexpected results
when calling external utilities like
make from Emacs.
This library works around this problem by copying important environment variables from the user's shell.
ELPA packages are available on Marmalade and MELPA. Alternatively, download
the latest release or clone the repository, and install
Add the following to your
(when (memq window-system '(mac ns)) (exec-path-from-shell-initialize))

You can copy values of other environment variables by customizing
exec-path-from-shell-variables before invoking
exec-path-from-shell-initialize, or by calling
This function may also be called interactively.
C-h f exec-path-from-shell-initialize
C-h f exec-path-from-shell-copy-env
