OK, I got the problem: when I define these tcolorbox environments in the
document, all works after I do two things
1) C-c C-n
2) reftex-parse-all
But when I put the definitions into a separate latex style file, neither
reftex nor auctex knows about them and the above two steps won't help.
I am attaching the following file tcbcolor_test.tex . This one works after
I open it in Emacs and do 1) and 2) above.
\documentclass{article}
\usepackage[theorems]{tcolorbox}
\usepackage{cleveref}
\newtcbtheorem[
crefname={definition}{definitions}
]
{defn}{Definition}{}{defn}
%theorem
\newtcbtheorem[
use counter from=defn,
crefname={theorem}{theorems}
]
{thm}{Theorem}{}{thm}
%\usepackage{my}
\begin{document}
\begin{thm}[label={thm:1}]{Big One}{}
$1=2$
\end{thm}
\begin{defn}[label={defn:1}]{Bigdef}{}
BIG.
\end{defn}
In \cref{defn:1,thm:1}.
\end{document}
But if I put the preamble into my.sty, so I have this tcbcolor_test1.tex
\documentclass{article}
\usepackage{my}
\begin{document}
\begin{thm}[label={thm:1}]{Big One}{}
$1=2$
\end{thm}
\begin{defn}[label={defn:1}]{Bigdef}{}
BIG.
\end{defn}
In \cref{defn:1,thm:1}.
\end{document}
Then AUCTeX won't know about these thm and defn environments and reftex
won't offer them when I do C-c ).
