syntax highlighting / font lock for latex in emacs 21

syntax highlighting / font lock for latex in emacs 21

Hey folks,

I just upgraded to RedHat 8.0, and with it came emacs 21.2.1.  I'm using 
the same old .emacs file and such.  But for some reason, latex files 
will not automatically fontify (though emacs does go into LaTeX mode, 
and global-font-lock is on).  When I force fontification using M-g M-g, 
only comments get fontified--not LaTeX commands, etc.

I'm supposed to be writing a paper and this is so disconcerting... 
please help!  I've attached my .emacs file, in case that helps.

Thanks in advance,
Steve

Re: syntax highlighting / font lock for latex in emacs 21

[Steve Petersen]

Sorry.  As always seems to happen, I figured it out not after the hour 
or so scouring the web, but instead only moments after actually posting 
somewhere and bugging people.  I've updated auctex using an rpm and 
everything suddenly works like a charm, though once again I have little 
understanding as to why.

Oh, except the colors are kinda ugly!  But I expect that can be fixed 
later, *after* the paper is written.

Thanks anyway,
Steve

Which version of AUCTeX do you have installed?  You make a point of
loading it.  AUCTeX RPMs can be found on
<URL:http://www.nongnu.org/auctex>, and I'd recommend using 11.14
(actually, I'd recommend a newer version, but I haven't got around to
releasing one).

I would want to point out that rpm files for RedHat 8.0 can also be
found for <URL:http://preview-latex.sourceforge.net> if you follow
the link to the project page and to Files from there.  If your paper
has any non-trivial amount of mathematics in it, a must.

I agree, but have not found out how to fix them, yet.  And I am the
maintainer of AUCTeX...  Shows you the incompetence that some projects
have to suffer under.

Okay, okay.  To each his own.  I happen to like 'em.

Customize them!

M-x customize-face [RET] font-latex-[TAB]

Or do it the old way, like I wrote in the font-latex.el file itself:

;; Changing colours
;;
;;  Okay, so you hate the colours I picked.  How do you change them you ask?
;;  First, find the font name to change using the command:

;;  without the semi-colon I'm using here ascomment delimiters, of course.

I'm sorry... I didn't mean to be the whiny ingrate!  Actually I'm the 
whiny but extremely grateful guy.  Thank you both for all the great, 
*free* work that has contributed so much to my getting through grad 
school still sane (so far).

A question about GTK file selection dialog and `use-dialog-box'

[Peter S Galbraith]

Hi all,

Using a GTK build of CVS Emacs, I see that `read-file-name' uses a GTK
file selector instead of the minbuffer.  I had to disable it because
it's very awkward to use compared to the minibuffer (no history or
completion).  The only advertised way to disable it is to unset
`use-dialog-box', which also disables the nice `y-or-n-p' and
`yes-or-no-p' pop-ups (I like thoese!).

It would be great if the GTK file selector's minibuffer area acted like
the minibuffer (history and completion).  If not, then consider
providing a way to disable the file selector without disabling
`y-or-n-p' and `yes-or-no-p' pop-ups.

Thanks,
Peter

It only uses the GTK file selector if the triggering event is a mouse
event.  So if you are using the keyboard, you won't get to see a GTK
file selector.

Unless, say, you are hitting upon a bug of AUCTeX that can trigger
calling read-file-name from update-menu-hook or so (which apparently
does not count as a keyboard event in that context).  The solution, of
course, is to fix that by delaying the guilty functions until the
LaTeX menu or respective keyboard functions actually get called.

I believe the behavior depends on the last actual event (although the event
may be totally unrelated to the execution of the update-menu-hook).

Uhm, GTK file selector provides TAB completion since the beginning of
time (or at least for four years).

You just type the few starting letters and press TAB: if it completes
to a directory name, it will enter it (then use "..[TAB]" to go one
level back if you need it), and if it completes to several file
names, it will filter them in the right side of the dialog.

Perhaps you're using some modified file selector dialog, instead of
the original one (Ximian and others have modified it in their
distributions).

Cheers,
Danilo

I know, but the GTK file selector doesn't have the required features to
replace the trusty minibuffer for me.

> Unless, say, you are hitting upon a bug of AUCTeX

No, this is when I hit the `compose MIME insertion' toolbar buttom in
MH-E.   Hmmm, maybe I can (optionally) locally-bind `use-dialog-box'
within that MH-E command...

Thanks for replying,
Peter

Oh.  Something must be wrong here then.  I'm using a CVS snapshot from
a few weeks ago, and I can't even click in the file dialog box to type
something in.  I can only navigate the directory tree using the mouse.

Having completion is good, thanks.  Can history be used as well?

Thanks,
Peter

If you mean Gtk+ from CVS, then latest releases contain different file
selector which is still in development, so you might want to
downgrade to 2.2.4 until that's sorted out.

No, I don't know of any history mechanism, but I may have missed
something.

I've added a variable use-file-dialog that you can customize.
