  emacs -Q

Type "# something" (without quotes).  The comment is not highlighted
in the font-lock-comment face, as expected.  comment-start and
comment-start-skip seem to have reasonable values.

If you delete the compiled version of cc-fonts, it works...

You mean, delete it and never compile it again, yes?

A bit of binary chopping shows that the bug first became visible after
this change:


  revno: 104401
  committer: Chong Yidong <cyd@stupidchicken.com>
  branch nick: trunk
  timestamp: Sat 2011-05-28 13:16:54 -0400
  message:
    Make CC modes inherit from prog-mode.

    * lisp/progmodes/cc-mode.el (c-mode, c++-mode, objc-mode, java-mode)
    (idl-mode, pike-mode, awk-mode): Inherit from prog-mode.


I cannot see anything in the change with looks remotely suspicious,
however.  Except, of course, that AWK Mode is now constructed by a macro
of some complexity, doubly invoked.

Deleting cc-fonts.elc (thus allowing cc-fonts.el to be loaded) gets
fontification of AWK comments working for me, too.

I think I see the problem, it's with the macro `define-derived-mode'.
This creates an empty syntax table with (defvar awk-mode-syntax-table),
and does this before cc-awk.elc has been loaded.  This thus stuffs the
proper definition of awk-mode-syntax-table.

Because of this, ?# doesn't have the open-comment syntax flag, thus
comments can't get fontified.

If I'm right about this, a solution would be to insert

   (makunbound 'awk-mode-syntax-table)
   
at the top of the mode initialisation.  Why on earth does
`define-derived-mode' have the temerity to create an empty, thus useless,
syntax table?  Maybe this should be taken out of the macro.

I still don't have a clue why this is happening.

That's interesting. I imagine in most cases, all the definitions are in
the same file, eg:

(defvar foo-mode-map ... )
(defvar foo-mode-syntax-table ... )
(define-derived-mode foo-mode ... )

cc-awk is unusual in that the actual mode is defined in cc-mode.el and
requires cc-awk.el as part of its execution.

Another option is to move awk-mode-syntax-table from cc-awk.el to
cc-mode.el (I see the mode-map and abbrev-table are already there).
Unbinding it might erase any user customization.

I wouldn't consider this as a solution.  I see a few solutions, tho:
- move the defvar from cc-awk to cc-mode.
- move the define-derived-mode to cc-awk (sounds natural, from my
  "I haven't looked at the code" point of view).
- add a ":syntax-table awk-mode-syntax-table" argument to define-derived-mode.

It's actually not empty: it inherits from the parent.  This is taken
directly from the original define-derived-mode, which was oddly meant
for end-users.
It also has the advantage to ensure that every major-mode defined with
define-derived-mode will have a foo-mode-syntax-table.

> Maybe this should be taken out of the macro.

Maybe so, yes.  I'm not completely sure.  In any case it's too late to
do that for Emacs-24.  But we could try it out in Emacs-25.

This doesn't work by itself. When calling `awk-mode', cc-awk.el is not
loaded early enough.

It doesn't work anyway.  ;-)

Undesirable.

That's beginning to sound serious.  CC Mode is structured so that the
interface with the "OS" bit of the host Emacs is in cc-mode.el.

I've tried :syntax-table nil, and this doesn't generate
awk-mode-syntax-table.  It appears to work.

OK.

One other thing is bothering me quite a bit.  Just before all this, at
L1530 in cc-mode.el is the line

    (defvar awk-mode-syntax-table)

.  This ought to prevent my solution above from working, but it doesn't.
Glenn, I think you put this line in.  Why?  Would it be OK to take it out
again?

BTW, I've found out why deleting cc-fonts.elc does what it does.  There
is a "(cc-require-when-compile 'cc-awk)" in cc-fonts.el.  When this file
isn't byte compiled, that form loads cc-awk.elc, and this happens before
the bulk of cc-mode.elc is loaded.  That form should probably be removed,
since it no longer serves a purpose.

Glenn, what on earth brought you to try deleting cc-fonts.elc?  It seems
a stroke of genius, but how did you come to consider it?  :-)

A defvar with no initvalue just suppresses a byte-compiler warning about
said variable being undefined. It doesn't actually define the variable,
so I think that line should stay there, to stop the compiler complaining
about an undefined variable in

  (set-syntax-table awk-mode-syntax-table)

(So by the way I think this means cc-bytecomp-defvar is no longer
needed. Also cc-bytecomp-defun can be replaced by declare-function.)

I saw from the ChangeLog that cc-fonts was the most recent part of
cc-mode to be changed, so I tried reverting that commit. To make it take
effect, I deleted the old cc-fonts.elc rather than recompiling it.

Well, you learn something new every day.  :-)  I'd thought that (defvar
foo nil) and (defvar foo) were the same.  They're not.

OK.

There's the rub.  The more such "tidying up" changes are made in
savannah, the more difficult it becomes for me to synch changes with the
upstream CC Mode.  There're already > 80 such differences in cc-mode.el
alone.

And the irony is, AWK code doesn't use cc-fonts.elc for its
fontification; it uses a simple regexp based model.  ;-)

(defvar foo)

works to silence the compiler since at least Emacs 21.4 (I think).

declare-function works since Emacs 23.1, and exists as a no-op in Emacs
22.2 and 22.3.

I hope that one day cc-bytecomp can just be removed. The part that deals
with "an older CC Mode with outdated macros [being] loaded during
compilation" is clever, but IMO just adds a bunch of complexity to solve
a problem that doesn't need solving. Files should be compiled in batch
mode in a separate Emacs instance.

There're quite a few other such constructs.  Does it work under XEmacs?
If so which versions.  They're all things which are easy to check, but
cumulatively it's a massive time sink.

Again, what about XEmacs?

I'd agree with you about its eventual removal.  Clearly there was a big
problem to solve - something like cc-bytecomp.el doesn't get knocked
together in a couple of hours.  I suspect Martin Stjernholm was having
big problems with his various versions during development, and that
cc-bytecomp is more for me and colleagues rather than ordinary users.

I tend to agree ;-)

It's your call as to how relevant you think other varieties of Emacs are
to you and to others, and how much effort you think it's worth investing
in supporting them.

If it takes a lot of time to ensure that the latest cc-mode runs on a
bunch of platforms, then personally I think that's time that could be
better spent, in making it work better on fewer.

How about switching CC Mode repo from CVS to Bazar?  Then merges would
be seamless.

Are you saying that emacs-lisp-byte-compile-and-load's interactive use
should be discouraged?  I use it quite frequently to test changes in
the same Emacs session where I make those changes.  If we think it's
not a good idea, then we should deprecate the command and remove the
corresponding menu item.

No; I use it like that too. All I'm saying is, when you download
someone's foo-mode to install it on your system, foo-mode's installation
process should compile it using batch mode.

In fact, I'm not even saying that, because for a single, simple foo.el
compiling it in a running Emacs is probably fine. I'm just saying that
if I were compiling something as complex as cc-mode, I'd definitely do
it in batch-mode, and would not try to support the case where an older
cc-mode is already loaded in the compiling Emacs.

Some time soon I'll probably be forced to change, since SourceForge won't
be supporting CVS for ever.

The time taken is checking each individual change.  Some of them will
break support for older Emacsen.  Ediff works well.
