Subject: hi-lock-mode doesn't work with emacs -Q.
Date: Thu, 7 Jun 2007 10:26:51 +0100 [thread overview]
Message-ID: <20070607092651.GA1710@muc.de> (raw)
Hi, Stefan!
Start emacs -Q. (Emacs 22.1, of course). Visit a new file with:
C-x C-f foo.txt
. Type this:
This file is foo.txt.
. Enable hi-lock-mode and make "foo" a highlightable pattern:
M-x hi-lock-mode
C-x w h foo<CR><CR> ; accept the default hi-yellow face.
. This highlights the "foo" yellow, as expected. At the end of the
line, type:
foo
. This new "foo" doesn't get highlighted. It should be.

Partial diagnosis:
(i) The bug happens even when global-hi-lock-mode is enabled.
(ii) after-change-functions is nil. It ought to be
(jit-lock-after-change t).
(iii) font-lock-mode is t.
How can font-lock-mode be t, whilst at the same time there is no
after-change function? Is this some optimisation in Font Lock mode
that only sets after-change-functions when font-lock-keywords is
non-nil?
hi-lock.el doesn't seem to be violating Font Lock's proper calling
conventions in any way.
Stefan, I think you're the best person to fix this.
