我正在尝试创建两个命令：
\collect存储字符串/文本的命令。\callcollection调用放置在命令之前的所有这些存储文本的命令（无需任何配置，只需打印文本内容）。
我试图模仿parnote 包装策略，但我很难适应它。（而且我也不理解“收集笔记”并随后调用它们的机制。）
基本上，我所有的尝试都失败了，我不知道发生了什么......
这里有一个虚拟的 MWE：
\documentclass{article}
\newcommand{\collect}[1]{#1}
\newcommand{\callcollection}{-- Call all previous texts in "collect" --}
\begin{document}
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer aliquet
quam\collect{Vitae mauris tempus!} consequat. In nec neque vitae magna
pulvinar pretium.\collect{Nunc purus augue, egestas vitae lobortis at,
eleifend quis erat. Vestibulum ante ipsum primis in faucibus orci luctus
et ultrices posuere cubilia Curae.} In aliquet tortor sed tellus
\collect{Porta} et elementum diam sagittis.
\callcollection
% Here I want the \callcollection command place all the texts in previous paragraph

这是一个基于Lua的方法：
\documentclass{article}
\directlua{buffer = {}}
\newcommand{\collect}[1]{#1\directlua{table.insert(buffer, [[#1]])}}
\newcommand{\callcollection}{\directlua{
tex.sprint(table.concat(buffer, " "))
buffer = {}
}}
\begin{document}
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer aliquet
quam\collect{Vitae mauris tempus!} consequat. In nec neque vitae magna
pulvinar pretium.\collect{Nunc purus augue, egestas vitae lobortis at,
eleifend quis erat. Vestibulum ante ipsum primis in faucibus orci luctus
et ultrices posuere cubilia Curae.} In aliquet tortor sed tellus
\collect{Porta} et elementum diam sagittis.
\callcollection
% Here I want the \callcollection command place all the texts in previous paragraph

编辑： \collect现在还打印其参数（错误修复）

这scontents包裹提供了这样的存储/调用机制。将您想要存储的部分封闭在环境中scontents，然后使用 调用它\getstored。
\begin{scontents}[store-env=a_name]
text that you want to store
\end{scontents}
\getstored{a_name}
a_name是您选择的名称。
