empheq is a LaTeX meta-environment for emphasizing equation-like environments with boxes and stuff. All funky -- but by now, I am so spoiled by my Emacs/AUCTeX/Preview/RefTeX setup that I can't work without it. Turns out the hacking is quick and not bloody at all:
Getting empheq to work with PreviewLaTeX
Just put this in you document preamble (thanks to
David Kamstrup)
\usepackage[displaymath,floats,graphics,textmath]{preview}
\PreviewEnvironment[{[]{}}]{empheq}
Getting empheq to work with RefTeX
You basically need to put a term in
reftex-label-alist.
It is perhaps explained in the
RefTeX manual, but I found this
XEmacs page a few hundred times more readable.
The upshot is to put this line in your
.emacs:
(setq reftex-label-alist (quote (("empheq" ?e "eq:" nil nil nil))))
or put something to similar effect in the customization group.
