You can add additional file types to activate Lisp mode with a bit of emacs lisp. For example, to enable Lisp mode for files with extension ".cl" ".gdl" and ".gendl" you can do (e.g. in your ~/.emacs): (add-to-list 'auto-mode-alist '("\\.cl\\'" . lisp-mode)) (add-to-list 'auto-mode-alist '("\\.gdl\\'" . lisp-mode)) (add-to-list 'auto-mode-alist '("\\.gendl\\'" . lisp-mode)) On Sat, Feb 8, 2014 at 11:21 AM, Luís Oliveira <luismbo@gmail.com> wrote:

Where did you write your program? Was lisp-mode activated? If your file has a ".lisp" extension, Emacs should activate lisp-mode automatically.
