mdframed：如何更改标签和非编号标题之间的分隔符？

Question

问题

mdframed软件包中似乎有一个错误。使用theoremseparator密钥，应该能够更改定理的“标签”和标题之间的文本（“定理”是标签，“高斯”是标题）。它在通常情况下有效，但当我使用带星号的环境版本时，它不起作用。

你同意吗？这个问题能轻易解决吗？

谢谢！

\mdtheorem[style=myStyle]{theo}{Theorem}


\begin{document}
\begin{theo}[test]
Hi

\begin{theo*}[test]
Hi

是的，这是 定义中的一个错误\mdtheorem。下面我展示了修复方法：

   }%
 }
\makeatother

\mdfdefinestyle{myStyle}

\mdtheorem[style=myStyle]{theo}{Theorem}


\begin{document}
\begin{theo}[test]

\end{theo}

\begin{theo*}[test]
Hi
\end{theo*}

\end{document}

问题是

    \newenvironment{#2*}[1][]{%
      \ifstrempty{##1}{\let\@temptitle\relax}{\def\@temptitle{:\ ##1}}% <- the problem is here
      \begin{mdframed}[#1,frametitle={\strut#4\@temptitle}]}%
      {\end{mdframed}}%

其中，应该有\mdf@theoremseparator
