如何获取章节第一节和最后一节的名称？

我想获取章节第一节和最后一节的名称，并将其分别打印到每个章节的目录中。因此，我想使用 -package etoc。在etoc32.4 节的 -documentation 中描述了一个宏，他们使用它来打印章节的统计信息。我想推导出这一点，因此目录打印如下：

Table of Contents
Chapter 1  Chaptername
<Name of first Section> to <Name of last Section>
Chapter 2  Chaptername
etc

我的知识还不够，我不懂宏。有没有人能帮我，或者我应该放弃这个想法？

\documentclass[
    twoside,
    12pt,
    ]{book}
\usepackage{luaotfload}
\usepackage{fontspec}
\usepackage{etoc}
\begin{document}
\tableofcontents
\chapter{Chapter 1}
\section{Section 1}
\section{Section 2}
\section{Section 3}
\chapter{Chapter 1}
\section{Section 4}
\section{Section 5}
\end{document}

答案1

答案已编辑，以处理空章节的情况，并使用\etociffirst条件etoc 1.08或更高版本。

\documentclass[
    twoside,
    12pt,
    ]{book}
% This is commented out to compile with pdflatex:
%    \usepackage{luaotfload}
%    \usepackage{fontspec}

\usepackage{etoc}

% here some empty definitions to get a warning in case we 
% overwrite already existing macros from class or packages
\newcommand*\firstsectionname   {}  
\newcommand*\firstsectionnumber {}
\newcommand*\firstsectionpage   {}

% auxiliary command, to be executed from within the etoc user-defined
% section style
\newcommand*\storefirstsectiondata {%
         \let\firstsectionname  \etocthelinkedname
         \let\firstsectionnumber\etocthelinkednumber
         \let\firstsectionpage  \etocthelinkedpage
         }%

% A boolean to handle the case of chapters with no sections.
% To handle booleans in a more LaTeX way, use rather etoolbox package.

答案2

这是另一个选项，使用tocloft和titlesec包装：

\documentclass{book}
\usepackage[explicit]{titlesec}
\usepackage{etoolbox}
\usepackage{tocloft}

\gdef\firstsection{}
\gdef\lastsection{}

\setcounter{tocdepth}{0}

\makeatletter
\newlength\mylen
\renewcommand\cftchappresnum{\@chapapp~}
\settowidth\mylen{\bfseries\cftchappresnum\cftchapaftersnum}
\addtolength\cftchapnumwidth{\mylen}
\makeatother

\titleformat{\section}
  {\normalfont\Large\bfseries}
  {\thesection}
  {1em}
  {%
    \ifnum\value{section}=1\relax\gdef\firstsection{#1}\fi%
    \gdef\lastsection{#1}#1%
  }

\makeatletter
\pretocmd{\chapter}{%
  \ifnum\value{chapter}=0\relax\else
    \ifnum\value{section}>1\relax
      \protect\addtocontents{toc}{\firstsection~to~\lastsection\par}
    \fi
  \fi}{}{}
\AtEndDocument{%
  \ifnum\value{section}>1\relax
    \protect\addtocontents{toc}{\firstsection~to~\lastsection\par}
  \fi  
}
\makeatother

\begin{document}

\tableofcontents

\chapter{A test chapter}
\section{Test section one one}
\section{Test section one two}
\section{Test section one three}

\chapter{Another test chapter}
\section{Test section two one}
\section{Test section two two}
\section{Test section two three}
\section{Test section two four}

\chapter{A test chapter without sections}

\chapter{A last test chapter}
\section{Test section three one}
\section{Test section three two}
\section{Test section three three}
\section{Test section three four}
\section{Test section three five}
\section{Test section three six}

\chapter{Another test chapter without sections}

\end{document}
