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.
