On OS X (and perhaps elsewhere) the $PATH environment variable and
|
|
`exec-path' used by a windowed Emacs instance will usually be the
|
|
system-wide default path, rather than that seen in a terminal
|
|
window.
|
|
|
|
This library allows the user to set Emacs' `exec-path' and $PATH
|
|
from the shell path, so that `shell-command', `compile' and the
|
|
like work as expected.
|
|
|
|
It also allows other environment variables to be retrieved from the
|
|
shell, so that Emacs will see the same values you get in a terminal.
|
|
|
|
If you use a non-POSIX-standard shell like "tcsh" or "fish", your
|
|
shell will be asked to execute "sh" as a subshell in order to print
|
|
out the variables in a format which can be reliably parsed. "sh"
|
|
must be a POSIX-compliant shell in this case.
|
|
|
|
Note that shell variables which have not been exported as
|
|
environment variables (e.g. using the "export" keyword) may not be
|
|
visible to `exec-path-from-shell'.
|
|
|
|
Installation:
|
|
|
|
ELPA packages are available on Marmalade and MELPA. Alternatively,
|
|
place this file on a directory in your `load-path', and explicitly
|
|
require it.
|
|
|
|
Usage:
|
|
|
|
(require 'exec-path-from-shell) ;; if not using the ELPA package
|
|
(exec-path-from-shell-initialize)
|
|
|
|
Customize `exec-path-from-shell-variables' to modify the list of
|
|
variables imported.
|
|
|
|
If you use your Emacs config on other platforms, you can instead
|
|
make initialization conditional as follows:
|
|
|
|
(when (memq window-system '(mac ns))
|
|
(exec-path-from-shell-initialize))
|
|
|
|
Alternatively, you can use `exec-path-from-shell-copy-envs' or
|
|
`exec-path-from-shell-copy-env' directly, e.g.
|
|
|
|
(exec-path-from-shell-copy-env "PYTHONPATH")
