Subject: Adding and running a major mode hook
Date: Sat, 26 Apr 2014 10:25:52 -0700 (PDT) [thread overview]
Message-ID: <ed13f213-3af4-4f7e-b3d8-90543fc5b4b9@googlegroups.com> (raw)
I think that a hook is the right way for me to allow users some customization in my major mode.
I have a list that is used to create font lock constructs, and I'd like to allow users to add to that list before my code processes it into font lock constructs.
What I have now is basically:
(setq content-list...)
(mapc 'create-constructs content-list)
What I've tried to do is
(setq content-list ...)
(defvar add-user-content-hook nil)
(defun add-user-content (input)
(add-hook 'add-user-content-hook
(lambda () (add-to-list 'content-list input))))
(run-hooks 'add-user-content-hook)
(mapc 'create-constructs content-list)
With the intention that users put something like
(add-user-content '("my content"))
in their .emacs
This code doesn't generate any errors, but it doesn't work either.
Reading about hooks in the documentation makes me think that I have a conceptual misunderstanding about the manner and sequence in which code in mymode.el is executed. Specifically, what is the difference between putting (run-hooks... in (define-derived-mode ... vs putting (run-hooks... somewhere in the mode's code (as I have done above)?
