我一直在尝试收集 tex 标记（去标记化）并在稍后用 输出它们\scantokens。问题是不能删除重复的参数（#）理想情况下，将所有内容作为字符串读取直到某个标记会很棒，但这可能需要逐个读取标记并将其 catcode 更改为字符串并在某些位置添加空格。
例如我想收集thebibliography并输出到文档末尾。当我取消注释时会出现问题\def\path...。它会给出一个错误! Parameters must be numbered consecutively.
例子：
\documentclass{article}
\usepackage{environ}
\makeatletter
\def\printOrigBibliography{%
\let\thebibliography\copythebibliography
\let\endthebibliography\copyendthebibliography
%% fix of space after \verb token
\let\origverb\verb
\def\verb##1{\origverb##1}%
\expandafter\scantokens\expandafter{\my@envthebibliography\noexpand}\relax
}
\AtBeginDocument{%
\environbodyname\envthebibliography
\let\copythebibliography\thebibliography
\let\copyendthebibliography\endthebibliography
\RenewEnviron{thebibliography}
{\xdef\my@envthebibliography{%
\noexpand\begin{thebibliography}%
\expandafter\detokenize\expandafter{\envthebibliography}%
\noexpand\end{thebibliography}}%
}%
}
\AtEndDocument{\printOrigBibliography}
\makeatother
\begin{document}
\begin{thebibliography}{1}
%\def\path#1{#1}
\bibitem{R}
aa \verb|a_a| bb
\end{thebibliography}
Final words
\end{document} \end{document}
我可以将一些重复的参数降低一级吗？我尝试使用以下命令将其删除：
\expandafter\scantokens\expandafter{%
\expandafter\long\expandafter\def\expandafter\fooo
\expandafter{\my@envthebibliography}\noexpand}\relax
\fooo
但后来我\verb又遇到问题了。

将参考书目存储在盒子里不是更简单吗？
\documentclass{article}
\let\origthebibliography\thebibliography
\let\origendthebibliography\endthebibliography
\newsavebox{\bibliographybox}
\renewenvironment{thebibliography}
{\global\setbox\bibliographybox=\vtop\bgroup\origthebibliography}
{\origendthebibliography\egroup}
\AtEndDocument{\unvbox\bibliographybox}
\begin{document}
\begin{thebibliography}{1}
\def\path#1{#1}
\bibitem{R}
aa \verb|a_a| bb
\end{thebibliography}
Final words \cite{R}
\end{document}
