Load environment variables into Emacs from a shell script:
#+BEGIN_SRC emacs-lisp
(defun source-env-file (file)
(interactive "fFile: \n")
(let ((var-re "\\(.+?\\)=\\(.+\\)$"))
(with-temp-buffer
(shell-command (concat "source " file " > /dev/null && env")
(current-buffer))
(save-match-data
(while (re-search-forward var-re nil t)
(setenv (match-string 1) (match-string 2)))))))
