Some source files begin with the line
;; -*- Mode:Common-Lisp; ;; -*- Mode:Lisp;A buffer is automatically set to be in lisp mode when such a file is displayed.
Alternatively, if you have files of Common Lisp code with extension other than .lisp , add the following code to your .lispworks file, substituting the extensions shown for your own. This ensures that Lisp mode is the major mode whenever a file with one of these extensions is viewed in the editor:
(editor:define-file-type-hook
("lispworks" "lisp" "slisp" "el" "lsp" "mcl" "cl")(buffer type)
(declare (ignore type))
(setf (editor:buffer-major-mode buffer) "Lisp"))
