如何将内容推迟到文档的后面部分？

如何将内容推迟到文档的后面部分？

我想创建一个问题集合，每个问题由问题本身、可选提示和可选解决方案组成。我想知道最好的方法是什么？

我可以使用一些帮助来定义一个界面，让我把问题放在一个地方，并分别在不同部分（或章节）打印相应的提示和解决方案。

有人暗示我，这个方案exsheets可能已经解决了一半的问题。

\documentclass{report} 
\usepackage[english]{babel} 
\usepackage{mathtools} 
\usepackage{blindtext} 

\numberwithin{equation}{section} 
\numberwithin{figure}{section} 
\numberwithin{table}{section} 

\newcounter{problem}
\newenvironment{problem}[1]{
{\bfseries\large{#1}\par}
}{}
\begin{document}
\part{Problems}
\section{Puzzle 1}
\begin{problem}{Pythagoras}
\blindtext
%\begin{hints}
%   \blindtext
%\end{hints}
%\begin{solution}
%   \blindtext
%\end{solution}
\end{problem}
\section{Puzzle 2}

\part{Hints}
\section{Puzzle 1 hint}
\section{Puzzle 2 hint}

\part{Solutions}
\section{Puzzle 1 solution}
\section{Puzzle 2 solution}

\end{document}

我也在LaTeX 社区。

就像你在问题中说的那样：这是可行的exsheets：

\documentclass{article}
\usepackage[english]{babel}
\usepackage{blindtext}

\usepackage{exsheets}

\SetupExSheets{ headings = block-subtitle }

% new property `hint':
\DeclareQuestionProperty{hint}

% a command to print all given hints
\NewDocumentCommand\printquestionhints{}{%
  \ForEachQuestion
    {%
      \IfQuestionPropertyT{hint}{##1}{%
        \ExSheetsHeading
          {block}               % headings style
          {Hint}                % heading
          {\QuestionNumber{##1}}% number
          {0}                   % points -- need to be zero here
          {0}                   % bonus points -- need to be zero here
          {##1}%                % ID
        \GetQuestionProperty{hint}{##1}%
        \par
        \medskip
      }%
    }%
}

\begin{document}

\section{Problems}
\begin{question}[subtitle=Pythagoras]
  This is the first problem.
  \SetQuestionProperties{ hint = This is a hint to the first problem. }
\end{question}
\begin{solution}
  This is the solution to the first problem.
\end{solution}

\begin{question}[subtitle=Another Problem]
  This is the second problem.
\end{question}
\begin{solution}
  This is the solution to the second problem.
\end{solution}

\begin{question}[subtitle=Yet Another Problem]
  This is the third problem.
  \SetQuestionProperties{ hint = This is a hint to the third problem. }
\end{question}
\begin{solution}
  This is the solution to the third problem.
\end{solution}

\section{Hints}
\printquestionhints

\section{Solutions}
\printsolutions

\end{document}

将提示和解决方案存储在储物箱中。

tcolorbox并非专门用于创建问题+解决方案集合，但可以用于此。

下一个代码几乎是从文档中复制而来。它展示了使用和记录工具的tcolorbox示例： ，，，。savelowertorecord\tcbstartrecording\tcbstoprecording\tcbinputrecords

savelowerto保存lower框部分以供进一步处理。在这种情况下，所有解决方案都分lower部分声明，这些部分将被记录下来，然后使用 读取\tcbinputrecords。

\documentclass{article}

\usepackage{lipsum}
\usepackage[most]{tcolorbox}

\NewTColorBox[auto counter,number within=section]{exercise}{+O{}}{ %

\lipsum[1]
\begin{exercise}
Compute the derivative of the following function:
\begin{equation*}
f(x)=\sin((\sin x)^2)
\end{equation*}
\tcblower
The derivative is:
\begin{align*}
f’(x) &= \left( \sin((\sin x)^2) \right)’
=\cos((\sin x)^2) 2\sin x \cos x.
\end{align*}
100\end{exercise}

\lipsum[2]
\begin{exercise}[no solution]
It holds:
\begin{equation*}
\frac{d}{dx}\left(\ln|x|\right) = \frac{1}{x}.
\end{equation*}
\end{exercise}

\lipsum[3]
\begin{exercise}
Compute the derivative of the following function:
\begin{equation*}
f(x)=(\sin(\sin x))^2
\end{equation*}
\tcblower
The derivative is:
\begin{align*}
f’(x) &= \left( (\sin(\sin x))^2 \right)’
=2\sin(\sin x)\cos(\sin x)\cos x.
\end{align*}
\end{exercise}
