;;; Commentary:

;; Simply activate this minor mode and the file in the buffer should
;; get byte-compiled after you safe it.
;;
;; Tip: Enable this mode wiht local file variables in the header or
;; footer of an elisp file, to byte compile it every time. You could
;; try for example the following code in the header of the file:
;; ;; -*- self-compile-mode: t -*-

;;; Code:

(provide 'self-compile-mode)

(defun autocompile nil
  "compile itself if ~/.emacs"
  (interactive)
  (require 'bytecomp)
  (if self-compile-mode
      (byte-compile-file (buffer-file-name))))

(define-minor-mode self-compile-mode
  "Toggle Self Compile mode.
With no argument, this command toggles the mode.
Non-null prefix argument turns on the mode.
Null prefix argument turns off the mode.

When Self Compile mode is enabled, the file gets
byte compiled after saving."
      :init-value nil
      :lighter " Compile")
(add-hook 'after-save-hook 'autocompile)

;; Local variables:
;; self-compile-mode: t
