gnus-article-mode-hook does not fire when opening an article in Gnus

Question

I want to highlight keywords when I open an email (article) in Gnus. This is what I have so far.

(add-hook 'gnus-article-mode-hook (lambda() (highlight-phrase "\\(TODO\\|job\\|Mike\\)")))

I also tried this which did not work either.

gnus-article-prepare-hook

Answer 1

Works fine for me on Emacs25. A better way to debug this is not to use the lambda:

(defun ora-gnus-article-hook ()
  (message "test"))
(add-hook 'gnus-article-mode-hook 'ora-gnus-article-hook)

Now you can instrument ora-gnus-article-hook with C-u C-M-x to see when it's getting called. You can also continuously re-define ora-gnus-article-hook without having to update gnus-article-mode-hook. In fact, once you put a lambda into a hook, the only way to remove it from that hook is basically (setq gnus-article-mode-hook nil).
