;;; Code:

(require 'em-dirs)

;;;###autoload
(defun eshell/cdp ()
  "Change the directory all the way up to the project root.

Look for the project root and change the directory to it.  The
project root is defined as the directory with the `.git'
directory in it."
  (let ((project-dir (locate-dominating-file "." ".git")))
    (if project-dir
        (eshell/cd project-dir)
      (error "Can't locate project root"))))

;;;###autoload
(defun oni:eshell-buttonize-url ()
  "Turn every URL into a clickable button."
  (save-excursion
    (goto-char eshell-last-output-start)
    (while (re-search-forward
            "https?://[^ \n]+" eshell-last-output-end :noerror)
      (make-button (match-beginning 0) (match-end 0)
                   'action (lambda (button)
                             (browse-url (button-label button)))))))
