提取长文档的骨架

我正在写一篇长篇文档，其中的关键信息位于环境中（逐项列出要做的事情，方程式、引理、定理等），并由文本和证明分隔。

为了方便与合著者的沟通，我想制作一个较短版本的文档，其中仅包含结构（章节、小节……）和一些环境（实际上除了证明之外的所有内容）。

例如：

\documentclass{amsart}
\newtheorem{theorem}{Theorem}

\begin{document}
\section{Intro}
\begin{itemize}
\item todo 1
\item todo 2
\end{itemize}
bla bla bla
\section{First result}
\begin{theorem}
(hopefully) nice thing
\end{theorem}
\begin{proof}
bla bla bla
\begin{equation}
E=mc^2
\end{equation}
\end{proof}
\end{document}

应该编译为

\documentclass{amsart}
\newtheorem{theorem}{Theorem}

\begin{document}
\section{Intro}
\begin{itemize}
\item todo 1
\item todo 2
\end{itemize}
\section{First result}
\begin{theorem}
(hopefully) nice thing
\end{theorem}
\end{document}

这可以手动完成，但我的目标是更高效的解决方案。你能找到一个吗？

我编写了以下 python 代码，它似乎运行良好。

由于您想隐藏证明以及纯文本和其他部分，我只需将这些部分标记为\showtrue序言中的条件：

\documentclass{amsart}
\newif\ifshow
% \showtrue %%%% uncomment to show all 
\newtheorem{theorem}{Theorem}
\begin{document}
\section{Intro}
\begin{itemize}
\item todo 1
\item todo 2
\end{itemize}
\ifshow
bla bla bla
\fi
\section{First result}
\begin{theorem}
(hopefully) nice thing
\end{theorem}
\ifshow
\begin{proof}
bla bla bla
\begin{equation}
E=mc^2
\end{equation}
\end{proof}
\fi
\end{document}
