Subject: Redundant (harmful) duplication of run-hooks in define-globalized-minor-mode
Date: Sun, 13 Jan 2013 19:28:54 +0000 [thread overview]
Message-ID: <20130113192854.GA4853@acm.acm> (raw)
Hi, Emacs.
The situation here is the direct cause of bug #11152, where in CC Mode,
doc comments whose fontification is specified in a mode hook don't get
fontified properly, or at all. It would be good to fix this bug for
Emacs 24.3.
In define-globalized-minor-mode L72-75, the newly defined -enable-
function is added to both the following hooks:
change-major-mode-after-body-hook
after-change-major-mode-hook
. (These hooks are run before and after the major mode hook.)
It seems the hacker who formulated this macro was undecided whether to
run the -enable- function before or after the mode hooks, so decided
upon both as a compromise. This isn't harmless.
In particular, running `global-font-lock-mode-enable-in-buffers' before
the objc-mode-hook causes a one-time font-lock-keywords initialisation
to happen before a critical initialisation has been performed by that
hook.
Can some means be found so that `font-lock-mode' isn't called twice?
(For that matter, `global-hi-lock-mode-enable-in-buffers' doesn't need
calling twice, either.) Such a means might be the addition of another
parameter to define-globalized-minor-mode specifying when the -enable-
call should take place.
