Re: Byte Compile Question

[Xah Lee <xahlee@gmail.com>]

byte-compile elisp buffer on save, only if a byte-compiled file
exists.

(defun byte-compile-current-buffer ()
  "`byte-compile' current buffer if it's emacs-lisp-mode and compiled
file exists."
  (interactive)
  (when (and (eq major-mode 'emacs-lisp-mode)
             (file-exists-p (byte-compile-dest-file buffer-file-
name)))
    (byte-compile-file buffer-file-name)))

(add-hook 'after-save-hook 'byte-compile-current-buffer)

code part from Adolfo Benedetti.
