该tcolorbox包使用与通常不同的标签语法\label{name}：它使用label={name}。我可以AUCTeX/RefTeX用这种新语法输入环境标签tcolorbox吗？我还想知道我是否可以使用此语法使其他一些有用的功能工作。我经常RefTeX使用。reftex-renumber-simple-labels
这是一个展示这两种语法的文件，我有两个定理环境，标签编号顺序相反。当我运行M-x reftex-renumber-simple-labels这两个方程标签时，定理中的标签没有改变，事实上，这两个\ref命令的参数也（错误地）改变了。
\documentclass{article}
\usepackage{tcolorbox}

\newtcbtheorem{theorem}{Theorem}{}{}

\begin{theorem}[label={thm:2}]{Squares series}{}
$\sum 1/n^2<\infty$.
\end{theorem}
In \ref{thm:2}.
\end{document}
\begin{equation}
\label{eq:2}
\sum 1/n^2<\infty.
\end{equation}
\begin{theorem}[label={thm:1}]{Harmonic series}{}
$\sum 1/n=\infty$.

答案1
AUCTeX 提供了一个名为 的函数LaTeX-env-label-as-keyval来完成这项工作：它在环境的可选参数中插入一个键值标签。对于theorems来自 的库tcolorbox，您必须在样式文件中投入更多精力才能解析用 定义的环境\newtcbtheorem。AUCTeX 样式的原型如下所示：

为了使用此功能，请将变量自定义TeX-style-private为您选择的目录或将如下内容放入您的初始化文件中：
(setq TeX-style-private (expand-file-name "~/.emacs.d/auctex-styles"))
将上面的代码保存tcolorboxlib-theorems.el在该目录中并重新启动 Emacs。使用最新的 AUCTeX，它应该会在您打开 .tex 文件时加载样式。您必须告诉 AUCTeX 和 RefTeX 有关新定义的环境。我建议使用局部变量在每个文件上执行此操作。您的测试文件将如下所示：
\documentclass{article}
\usepackage{tcolorbox}
\tcbuselibrary{theorems}
\newtcbtheorem{theorem}{Theorem}{}{}
\begin{document}
\begin{theorem}[label={thm:2}]{Squares series}{}
$\sum 1/n^2<\infty$.
\end{theorem}
In \ref{thm:2}.
\end{document}
\begin{equation}
\label{eq:2}
\sum 1/n^2<\infty.
\end{equation}
\begin{theorem}[label={thm:1}]{Harmonic series}{}
$\sum 1/n=\infty$.
\end{theorem}
In \ref{thm:1}.
\begin{equation}
\label{eq:1}
\sum 1/n=\infty.
\end{equation}
\end{document}

打开此文件，C-c C-n如果需要，点击。然后theorem应该可以使用C-c C-e theorem RET。
Reg. reftex-renumber-simple-labels，它无法处理此语法。我没有机会检查原因。但确实，它会用当前的实现弄乱您的文档。
