mdframed 和 ntheorem 计数器

在下面的代码中，由 定义的计数器mdframed似乎无法被ntheorem环境访问，这是有问题的，但ntheorem可以通过 读取计数器mdframed。我找不到解决方法，而且似乎没有任何地方提到这个限制。

\documentclass[fleqn,11pt]{book}
\usepackage{amsmath}
\usepackage[amsmath]{ntheorem}
\usepackage[ntheorem,framemethod=TikZ]{mdframed}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%\newmdtheoremenv{theorem}{Theorem}    % uncomment this line
\newtheorem{theorem}{Theorem}[chapter] % comment this line
\newtheorem{definition}[theorem]{Definition}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{document}
text text text text text text text text text text text text  
\begin{definition}[Definition]
text text text text text text text text text text text text  
\end{definition}
text text text text text text text text text text text text  
\begin{theorem}[Theorem]
text text text text text text text text text text text text  
\end{theorem}
text text text text text text text text text text text text  
\end{document}

答案1

至少在文档中，这似乎是一个“错误”。只需切换声明即可：

\newtheorem{definition}{Definition}
\newmdtheoremenv{theorem}[definition]{Theorem}

或者声明一个“虚拟”定理环境并根据这个环境定义所有内容：

\newtheorem{dummy}{dummy}[chapter]
\newmdtheoremenv{theorem}[dummy]{Theorem}
\newtheorem{definition}[dummy]{Definition}

（这可能对正确发布声明有用\theoremstyle）。

\newtheorem{dummy}{dummy}[chapter]

\newmdtheoremenv{theorem}[dummy]{Theorem}

\theoremstyle{definition}
\newtheorem{definition}[dummy]{Definition}

编辑

处于开发状态的mdframedbug已经修复：

github 上的 mdframed

这是软件包中的解决方案xparse。目前，该解决方案尚未在当前版本中实现mdframed。

\documentclass[fleqn,11pt]{book}
\usepackage{amsmath}
\usepackage[amsmath]{ntheorem}
\usepackage[ntheorem,framemethod=TikZ]{mdframed}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\usepackage{xparse}
\RenewDocumentCommand\newmdtheoremenv{O{} m o m o }{
 \ifboolexpr{ test {\IfNoValueTF {#3}} and test {\IfNoValueTF {#5}} }%
    {\newtheorem{#2}{#4}}{%
     \IfValueTF{#3}{\newtheorem{#2}[#3]{#4}}{}%
     \IfValueTF{#5}{\newtheorem{#2}{#4}[#5]}{}%
    }%
  \BeforeBeginEnvironment{#2}{%
     \begin{mdframed}[#1]}%
  \AfterEndEnvironment{#2}{%
     \end{mdframed}}%
}

\newmdtheoremenv{theorem}{Theorem}    % uncomment this line
%\newtheorem{theorem}{Theorem}[chapter] % comment this line
\newtheorem{definition}[theorem]{Definition}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{document}
text text text text text text text text text text text text  
\begin{definition}[Definition]
text text text text text text text text text text text text  
\end{definition}
text text text text text text text text text text text text  
\begin{theorem}[Theorem]

\end{theorem}
