font-lock not working correctly

font-lock not working correctly

[Rodney Gordon II]

[-- Attachment #1.1.1: Type: text/plain, Size: 1015 bytes --]

I am using emacs21 on Debian sid, to start things off.
The only elisp I load is color-theme.el and cperl-mode.el, both latest
version.

Attached is a image, showing the problem, and my .emacs file.

With my setup, font-lock never seems to highlight things like it should.
It highlights, but maybe only 2 or 3 colors. I have tried c files and
perl files, which work perfectly fine on others' systems with emacs (I
don't know if their system is different or not).

What I get is shown on the attached image, which is hardly helpful :)
The odd thing is that if I run emacs -q and do the things in my .emacs
file *manually*, it highlights perfectly.

Have asked on #emacs on FreeNode, but nobody seems to have an idea :/
I am hoping I am doing something simple wrong..

Any help would be greatly appreciated. Please mail me directly.

Thanks,
-r

Have you tried M-x list-colors-display? Does it show more than eight 
ANSI colours? In xterm or Apple's Terminal.app I don't have more 
colours than these too ...

Yeah, it shows all of the colors. I've tried running emacs on X also,
same problem, font-lock still isn't working right.

Would these lines from my .emacs help?

(cond ((fboundp 'global-font-lock-mode)
        ;; Turn on font-lock in all modes that support it
        (global-font-lock-mode t)
        (setq jit-lock-mode t)
        ;; Maximum colors
        (setq font-lock-maximum-decoration t)))

As much as I wished this would work (I've been trying everything) ..
still didn't help..

I don't understand why it works if I do everything in my .emacs
manually, and it isn't the global elisp stuff because I tried moving
that out of the way and trying also, still didn't help.

I'm at a loss of what to do at this point :/

Thanks!

Check whether your colour theme changes things to dull! This can be 
done by M-x list-faces-display (also Edit menu -> Text properties -> 
List Faces). How many colours are there?

Check what cperl-mode.el contains to colourize the syntax and put a 
copy of this at the end (after 1. loading color-theme and setting your 
theme, 2. customizing font-lock as maximum) of your .emacs. Since you 
have a screenshot you could try to change some colours ans see whether 
this work.

Lots and lots of colors .. definately not what I'd call dull :)


Tried just doing 'emacs -q' .. then load the file, then 'M-x
cperl-mode', then 'M-x font-lock-mode' and it's all highlighted
correctly. Yet, putting the same in my .emacs, it's messed up again.
Seems the only way to get it to work is manually.. :/

Things are correct when I do what I just said above, however I have a
hard time believing its the color-theme.el because if I comment it out
of my .emacs file, the highlighting is still broken.

I have tried turning font-lock off, and then on again while I have the
perl file loaded, no help. As fas as finding what cperl-mode uses to
font-lock, I have no idea, because I am very new to lisp and just the
sheer size of that file scares me :)

Thanks for all your help, and I hope we can figure this out!

I think there's a bug in your .emacs file.  Start Emacs as follows:

    emacs -debug-init

This ought to show you pretty clearly if there is a syntax error, and
if so, where it is.

(Hint: I suspect the cperl face definition, as off is not a valid
face.  You could try to use default instead of off...)
