After studying documentation, I have taken a different approach.
Code for lisp-mode++.el is not as follows:
;;
(defconst tj-word-end "\\)\\b")
(defconst tj-lisp-user-keywords
(concat tj-word-begin
(regexp-opt '("and" "apply" "concatenate" "format" "funcall"
"list" "lambda"
"mapcar" "not" "print" "push" "return-from "
"setf" "setq")
) tj-word-end))
(make-local-variable 'lisp-font-lock-keywords-tj)
(defvar lisp-font-lock-keywords-tj
(list
(list tj-lisp-user-keywords '1 'font-lock-user-keyword-face))
"Additional keywords and groups for lisp-mode")
(add-hook 'lisp-mode-hook
'(lambda ()
(require 'extra-faces) ;; font-lock-user-keyword-face defined here
'turn-on-font-lock
;; I have tried both of the lines below, with no good effect
(put 'lisp-mode 'font-lock-defaults '(lisp-font-lock-keywords-tj))
;(cons font-lock-defaults lisp-font-lock-keywords-tj)
(message "lisp-mode++ loaded")))
(provide 'lisp-mode++) ;; .emacs has (require 'lisp-mode++)
;;
What works:
'add hook is being executed.
I see the message
Even with "debug on error" turned on, there are no errors.
the 'require form is being evaluated as
'font-lock-user-keyword-face appears as a defined variable.
lisp-font-lock-keywords-tj appears as a defined variable.
The regex part of the variable seems to work as tested with
re-builder
What doesn't work:
No syntax highlighting appears for the keywords.
c-h v font-lock-defaults => provides a printed representation
that does not show lisp-font-lock-keywords-tj as a component of
that variable.
Unfortunately I have not yet found any examples to work from. I suspect
that neither the 'put nor the 'cons calls are wrong.
Any help would be appreciated.
