prolog users?

[Solly Brown]

Hi,

Quick question for users of prolog under emacs:

How can I change the face of prolog comments (ie. lines starting with a 
% symbol)?

Strangely enough, it doesn't appear to be defined by 
"font-lock-comment-face". So I need to somehow tell emacs that lines 
beginning with % should use font-lock-comment-face, or I need to edit 
the actual face being used currently.

Any ideas?

Thanks, Solly

ps. i'm using prolog.el

C-u C-x = should tell you which face is used for
highlighting.  BTW in GNU Emacs 22 (thats the developer
version) it's font-lock-comment-face.

OK this is a bit weird. This is what I've got for the text properties of 
my comments:

face                 font-lock-comment-face
fontified          t

However my comments don't show up in the font-lock-comment-face. 
Instead, they appear to be showing up with "firebrick-italic" face.

If I change the properties of the font-lock-comment-face (making it 
green, say) then new comments that I type in do indeed appear in green. 
However, when I type C-l to refontify the existing comments, then 
instead of everything turning green, all of my new comments revert to 
firebrick-italic (and the old ones are unchanged). The text properties 
still claims that the  comments are using font-lock-comment-face, but 
clearly they're not.

Something very odd going on there. Any more suggestions?

Thanks, Solly

Consider the prolog.el from:

Brilliant! Turns out that the wacko behaviour was not due to my 
prolog.el file, but in fact a little bit of code in my .emacs file (I 
copied it from someone else's .emacs a couple of years ago, and forgot 
all about it until now).

Your suggestion of trying a different prolog.el version made me think 
about changing my .emacs file too, so thanks Markus....... =-). And 
thank you David for your suggestions also.

With which prolog.el is this now? The one I recommended is unrelated
to the one that ships with Emacs (not just a different version):
