I am writing a minor mode for enabling support for JML within Java files.
I realized the syntax highlighting with cc-mode's support for documentation comments.
It works if I set c-doc-comment-style to (jml javadoc) in a file-local variable. Enabling JML doc comments interactively (similar SO question) with
(add-to-list 'c-doc-comment-style '(java-mode . jml))
(c-setup-doc-comment-style)
does not work. (The call of c-setup-doc-comment-style is explicit mention in the documentation.)
Has anyone experience with interactive en- and disabling doc comment highlighting in cc-mode and can give me a hint on my mistake?
Or should I file a bug report?
Via the great font-lock-studio, I found out that the font-lock-keywords
are not updated by c-setup-doc-comment-style.
In particular the entry:
(lambda
(limit)
(c-font-lock-doc-comments jml-start-multiline limit jml--font-lock-doc-comments))
(0 nil)
is missing.
Tested with built-in cc-mode from GNU Emacs 26.1.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.22.30) of 2018-05-29.
