A GNU Emacs library to ensure environment variables inside Emacs look the same as in the user's shell.
Ever find that a command works in your shell, but not in Emacs?
This happens a lot on OS X, where an Emacs instance started from the GUI inherits a default set of environment variables.
This library works solves this problem by copying important environment variables from the user's shell: it works by asking your shell to print out the variables of interest, then copying them into the Emacs environment.
If you use a non-POSIX-standard shell such as 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'.
ELPA packages are available on Marmalade and MELPA. Alternatively, download
the latest release or clone the repository, and install
exec-path-from-shell.el with M-x package-install-from-file.
Add the following to your init.el (after calling package-initialize):
(when (memq window-system '(mac ns))
(exec-path-from-shell-initialize))This sets $MANPATH, $PATH and exec-path from your shell, but only on OS X.
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
exec-path-from-shell-copy-env, e.g.:
(exec-path-from-shell-copy-env "PYTHONPATH")This function may also be called interactively.
