;;; Commentary:

;; Small interface between gitto and Emacs.

;; Right now it only offers the `gitto-register' command which lets
;; you register repositories from within Emacs.  When called
;; interactively this command will try to register the git directory
;; of the file of the current buffer.

;;; Code:

(defgroup gitto nil
  "Gitto settings."
  :group 'applications)

(defcustom gitto-program "gitto"
  "The gitto executable."
  :group 'gitto
  :type 'string)

;;;###autoload
(defun gitto-registered-p (dir)
  "Check if DIR is a registered repository."
  (not (string-match-p "not registered"
                       (shell-command-to-string
                        (concat gitto-program " check " dir)))))

;;;###autoload
(defun gitto-register (dir)
  "Register DIR with gitto."
  (interactive (list (locate-dominating-file (buffer-file-name) ".git")))
  (unless dir
    (error "Not a git repository"))

  (shell-command (concat gitto-program " add " dir)))

;;;###autoload
(defun gitto-unregister (dir)
  "Unregister DIR with gitto."
  (interactive (list (locate-dominating-file (buffer-file-name) ".git")))
  (unless (and dir (gitto-registered-p dir))
    (error "Not a registered git repository"))

  (shell-command (concat gitto-program " remove " dir)))
