Exsheets 套件：在 Chapter-hook 選項中使用章節名稱

Question

我正在用exsheets包排版一本問題書。我希望解決方案的結構能夠重複問題集的結構。Chapter-hook和section-hook選項允許在列印新章節/部分的解決方案時將自訂程式碼新增至解決方案清單。這是我的 MWE：

\documentclass{book}
\makeatletter
  \@addtoreset{chapter}{part} % Reset \chapter numbering after each \part
\makeatother  
\usepackage{exsheets}
\SetupExSheets{
  chapter-hook = \chapter{Solutions to the chapter \thechapter},
  section-hook = \section{Solutions to the section \thesection},
}

\begin{document}
\tableofcontents

\part{Problems}
  \chapter{Mechanics}
    \section{Kinematics}
      \begin{question}
        A kinematics problem.
        \begin{solution}
          Solution to the kinematics problem.
        \end{solution}
      \end{question}

    \section{Dynamics}
      \begin{question}
        A dynamics problem.
        \begin{solution}
          Solution to the dynamics problem.
        \end{solution}
      \end{question}

  \chapter{Electricity}
    \section{Electrostatics}
      \begin{question}
        An electrostatics problem.
        \begin{solution}
          Solution to the electrostatics problem.
        \end{solution}
      \end{question}

    \section{Electrodynamics}
      \begin{question}
        An electrodynamics problem.
        \begin{solution}
          Solution to the electrodynamics problem.
        \end{solution}
      \end{question}

\part{Solutions}
\printsolutions

\end{document}

製作的目錄如下：

我想要實現的是取代1 Solutions to Mechanicscurrent 1 Solutions to the chapter 1，2 Solutions to Electricity而不是2 Solutions to the chapter 2等等。任何幫助表示讚賞。

Answer 1

透過包的引用解決方案nameref。章/節編號用作標籤名稱。

\documentclass{book}
\makeatletter
  \@addtoreset{chapter}{part} % Reset \chapter numbering after each \part
\makeatother
\usepackage{exsheets}
\usepackage{nameref}
\SetupExSheets{
  chapter-hook = \chapter{Solutions to \nameref{CHAP:\thechapter}},
  section-hook = \section{Solutions to \nameref{SEC:\thesection}},
}
\newcommand*{\chaplabel}{\label{CHAP:\thechapter}}
\newcommand*{\seclabel}{\label{SEC:\thesection}}

\begin{document}
\tableofcontents

\part{Problems}
  \chapter{Mechanics}\chaplabel
    \section{Kinematics}\seclabel
      \begin{question}
        A kinematics problem.
        \begin{solution}
          Solution to the kinematics problem.
        \end{solution}
      \end{question}

    \section{Dynamics}\seclabel
      \begin{question}
        A dynamics problem.
        \begin{solution}
          Solution to the dynamics problem.
        \end{solution}
      \end{question}

  \chapter{Electricity}\chaplabel
    \section{Electrostatics}\seclabel
      \begin{question}
        An electrostatics problem.
        \begin{solution}
          Solution to the electrostatics problem.
        \end{solution}
      \end{question}

    \section{Electrodynamics}\seclabel
      \begin{question}
        An electrodynamics problem.
        \begin{solution}
          Solution to the electrodynamics problem.
        \end{solution}
      \end{question}

\part{Solutions}
\printsolutions

\end{document}

標籤設定可以包含在\chapter和中\section：

• \mychapter新增的新命令\chaplabel。
• 儲存舊定義\chapter（例如透過套件letltxmacro）並重新定義\chapter以執行已儲存的版本並附加\chaplabel。
• 根據所需的參數類型（星形形式、可選參數），（重新）定義或多或少容易或更複雜。

版本，其中\chaplabel和\seclabel被用在<after code>的參數中\titleformat，由 package 提供titlesec：

\documentclass{book}
\makeatletter
  \@addtoreset{chapter}{part} % Reset \chapter numbering after each \part
\makeatother  
\usepackage{exsheets}
\usepackage{nameref}
\SetupExSheets{
  chapter-hook = \chapter{Solutions to \nameref{CHAP:\thechapter}},
  section-hook = \section{Solutions to \nameref{SEC:\thesection}},
}
\newcommand*{\chaplabel}{\label{CHAP:\thechapter}}
\newcommand*{\seclabel}{\label{SEC:\thesection}}

\usepackage{titlesec}
\titleformat{\chapter}{\normalfont\LARGE\bfseries}{\thechapter}{1em}%
  {}[\chaplabel]
\titleformat{\section}{\normalfont\Large\bfseries}{\thesection}{1em}%
  {}[\seclabel]

\usepackage{etoolbox}
\pretocmd\printsolutions{%
  \let\chaplabel\relax
  \let\seclabel\relax
}{}{\errmessage{Patching \noexpand\printsolutions failed.}}
\begin{document}
\tableofcontents

\part{Problems}
  \chapter{Mechanics}
    \section{Kinematics}
      \begin{question}
        A kinematics problem.
        \begin{solution}
          Solution to the kinematics problem.
        \end{solution}
      \end{question}

    \section{Dynamics}
      \begin{question}
        A dynamics problem.
        \begin{solution}
          Solution to the dynamics problem.
        \end{solution}
      \end{question}

  \chapter{Electricity}
    \section{Electrostatics}
      \begin{question}
        An electrostatics problem.
        \begin{solution}
          Solution to the electrostatics problem.
        \end{solution}
      \end{question}

    \section{Electrodynamics}
      \begin{question}
        An electrodynamics problem.
        \begin{solution}
          Solution to the electrodynamics problem.
        \end{solution}
      \end{question}

\part{Solutions}
\printsolutions
\end{document}

避免無限遞歸的技巧評論是在處理 的章節之前禁用\chaplabel和。\seclabel\printsolutions

與開關略有不同\ifwithlabels。然後可以對未編號的章節停用標籤設置，例如：

[...]
\newif\ifwithlabels
\newcommand*{\chaplabel}{\ifwithlabels\label{CHAP:\thechapter}\fi}
\newcommand*{\seclabel}{\ifwithlabels\label{SEC:\thesection}\fi}

\usepackage{titlesec}
\titleformat{\chapter}{\normalfont\LARGE\bfseries}{\thechapter}{1em}%
  {}[\chaplabel]
\titleformat{\section}{\normalfont\Large\bfseries}{\thesection}{1em}%
  {}[\seclabel]

\usepackage{etoolbox}
\pretocmd\printsolutions{%
  \withlabelsfalse
}{}{\errmessage{Patching \noexpand\printsolutions failed.}}

\begin{document}
\tableofcontents

\withlabelstrue
\part{Problems}
