modify syntax highlighting in auctex

modify syntax highlighting in auctex

[Fabian Braennstroem]

Hi,

all I want to modify syntax highlighting in auctex for the
use of beamer documents. Each frame/slide starts with the keyword
'frametitle' and now I want that is has the same style like the
'subsection' keyword, but with a different color, e.g.
green.
I found in 'font-latex.el' the part where 'subsection' is
defined and tried to add:

   ("title-3" ("frametitle")
   font-latex-title-3-face 2 (command 1 t))

to change the style to my own config, but it doesn't work.
There is probably another part where subsection is somehow
defined.

The whole frame-environment looks like:

\frame
{
\frametitle{ something }
  some text
}

Maybe, it is even possible to change the color of the words
frame and framtitle and enlarge and color the title-text!?

Greetings, Fabian

The manual explains how to do this, see (info "(auctex)Font Locking").

The following patch (against current CVS [1]) for style/beamer.sty
enables \subsection-like highlighting of \frametitle:

You may also add your own keywords as the manual suggests, but this is
done no matter if you actually use the beamer class or not:

,----[ (info "(auctex)Font Locking") ]
|    You can add your own sectioning commands be adding them to the
| keyword lists: `font-latex-match-sectioning-0-keywords'
| (`font-latex-sectioning-0-face') ...
| `font-latex-match-sectioning-5-keywords'
| (`font-latex-sectioning-5-face').
`----

I.e. (setq font-latex-match-sectioning-3-keywords (list "frametitle"))
should do the trick, see `C-h v font-latex-match-sectioning-3-keywords
RET' for more.

Bye, Reiner.

[1] probably it wont work with AUCTeX <= 11.55 because some functions
    have been renamed.

Do other LaTeX classes for producing slides have special macros for
titles as well?  In this case we could add a new keyword class for
such titles instead of using an arbitrary level from the sectioning
keyword classes.  Because in the latter case one would screw up the
size hierarchy of sectioning keyword classes if one wanted to have the
titles in slides be fontified in a different size.

Don't know.  I only use beamer for slides.

I agree that it is arbitrary.

A different approach would be to defcustom a new variable (say
LaTeX-beamer-frametitle-sectioning-level) specifying the level.

What I found with help of
<URL:http://www.miwie.org/presentations/presentations.html>:

beamer:       \frametitle
foiltex:      \foilhead
(HA-)prosper: integrated in \begin{slide}{<title>}
pdfscreen:    \title
rayslides:    \newslide
seminar:      none
slidenotes:   integrated in \begin{slide}[<title>]
TeXpower:     \foilhead

A little better, but still ... if somebody wanted the titles to be
green, like Fabian?

Yes.

Thanks! Somehow, both example don't work. The patch probably
just because I patched the beamer.el by hand; I will try the
correct way. Using the no-patch variant nothing happens and
when I try to describe variables with 'C-h v ' I just find
'font-latex-match-sectioning-3-keywords'; there are no other
sectioning variables available!?

Aeh, just found that I use auctex 11.52 ... I actually
already installed 11.55, but this happens when mixing two
different package manager (archlinux and gentoo); stupid. I
will clean up my system and try it again.

For AUCTeX <= 11.55 (including 11.55!) it should work with...

  (setq  font-latex-match-title-3-keywords (list "frametitle"))

Maybe one of the next versions of AUCTeX will support it
out-of-the-box, see
<URL:http://thread.gmane.org/slrndeuk91.18j.fab@node1.ddorf.de>.

Thanks! Works nice.
