Following up the discussion in bug#57003.
Consider the following file:
------------
# -*- mode:my/test -*-
This is test with keyword to be fontified.
# Local Variables:
# eval: (setq unsafe-variable t)
# End:
-------------
Then, consider the following major mode:
(define-derived-mode my/test-mode text-mode "Test"
""
(add-hook 'hack-local-variables-hook
(lambda ()
(setq-local my/test-mode-keywords '(("keyword" .
font-lock-keyword-face)))
(setq font-lock-defaults '(my/test-mode-keywords)))
nil 'local))
1. emacs -Q
2. Evaluate the major mode definition
3. Open the file
4. Answer "y" in the unsafe variable prompt
5. Observe "keyword" not being fontified.
6. Expected: "keyword" fontified using font-lock-keyword-face.
I can also reproduce using
(define-derived-mode my/test-mode text-mode "Test"
""
(hack-local-variables)
(setq-local my/test-mode-keywords '(("keyword" . font-lock-keyword-face)))
(setq font-lock-defaults '(my/test-mode-keywords)))
The fontification works as expected with
(define-derived-mode my/test-mode text-mode "Test"
""
(setq-local my/test-mode-keywords '(("keyword" . font-lock-keyword-face)))
(setq font-lock-defaults '(my/test-mode-keywords)))
Also reproduced on Emacs master.
