使用 \printsolutions 对齐 Exsheets 答案

Question

使用 exsheets 包时，我遇到了 \printsolution[all] 的问题。

 \documentclass[UTF8,11pt,a4paper]{book}
\usepackage{kantlipsum}
\usepackage[load-tasks=true]{exsheets}

\DeclareInstance{exsheets-heading}{exclist}{default}{
  runin = true ,
  number-post-code = \space ,
  attach = { main[r,vc]number[l,vc](-3em,0pt) } ,
  above = 0pt,
  below = 0pt 
}
\SetupExSheets{
%  solution/print = true , 
  headings = exclist ,
  headings-format = \bfseries, 
%  counter-format = ch.qu ,
  counter-within = chapter
}

\usepackage{scrextend}% needed with a KOMA-Script class, `addmargin' environment
\usepackage{etoolbox}
\AtBeginEnvironment{question}{\addmargin[3em]{0em}}
\AtEndEnvironment{question}{\endaddmargin}
\AtBeginEnvironment{solution}{\addmargin[3em]{0em}}
\AtEndEnvironment{solution}{\endaddmargin}


\begin{document}

\chapter{One}

\section{Sec.\thesection }
This is  normal  text. 

\section*{Using solution environment in section  }

\begin{question}
    This is sample question 1.
\end{question}

\begin{solution}
    This is sample solution 1. 
\end{solution}

\begin{question}
    This is sample question 2.
\end{question}

\begin{solution}
    This is sample solution 2. 
\end{solution}

This is normal text. This is normal text. This is normal text. This is normal text. This is normal text. 

\section*{Using printsolutions at the end}

\printsolutions

This is normal text. This is normal text. This is normal text. This is normal text. This is normal text. 

\end{document}

输出：

exsheet 包在本节中运行良好，但在书末使用 \printsolutions 时，答案超出了页边距。我不知道如何纠正它，有人能帮助我吗？谢谢！

Answer 1

由于解决方案环境未被使用，因此\printsolutions \AtBeginEnvironment{solution}{...}对在那里打印的解决方案没有影响。

解决方案：使用pre-hook和post-hook选项来提出问题和解决方案：

\SetupExSheets{
  question/pre-hook = \addmargin[3em]{0em} ,
  question/post-hook = \endaddmargin ,
  solution/pre-hook = \addmargin[3em]{0em} ,
  solution/post-hook = \endaddmargin
}

solution如果通过通过 环境，则在打印的每个解决方案之前和之后将使用相应的代码\printsolution。

完整示例：

\documentclass[11pt,a4paper]{book}
\usepackage{kantlipsum}
\usepackage{exsheets}

\DeclareInstance{exsheets-heading}{exclist}{default}{
  runin = true ,
  number-post-code = \space ,
  attach = { main[r,vc]number[l,vc](-3em,0pt) } ,
  above = 0pt,
  below = 0pt 
}
\SetupExSheets{
%  solution/print = true , 
  headings = exclist ,
  headings-format = \bfseries, 
  counter-within = chapter
}

\usepackage{scrextend}% needed with a KOMA-Script class, `addmargin' environment

\SetupExSheets{
  question/pre-hook = \addmargin[3em]{0em} ,
  question/post-hook = \endaddmargin ,
  solution/pre-hook = \addmargin[3em]{0em} ,
  solution/post-hook = \endaddmargin
}
