我在类文档中有几个部分book。我想在其标题页中打印当前部分的章节范围。
我知道该如何做吗？
我知道该\tableofcontents命令会创建一个toc文件，但我完全不知道如何提取其章节行来打印特定的章节范围\part。
\documentclass{book}
\usepackage{titlesec}
\titleformat{\part}[display]
{\centering\huge}
{\partname~\thepart}
{0pt}
{}
[\Large Chapters range goes here]
\begin{document}
\part{Introduction}
\chapter{Algebra}
\section{sec one} \subsection{subsec one} \subsection{subsec two} \section{sec two}
\chapter{Geometry}
\section{sec one} \section{sec two} \subsection{subsec one} \subsection{subsec two}
\end{document}
答案1
以下代码在文档末尾插入适当的\label和，然后检索它们以构建章节范围。它假设使用 numberic ( ) 章节编号，并且不考虑单章部分。\part\arabic
\documentclass{book}
\usepackage{refcount}
\usepackage{titlesec}
\titleformat{\part}[display]
{\centering\huge}
{\partname~\thepart}
{0pt}
{}
[\Large Chapters
\inteval{\getrefnumber{part-\arabic{part}}+1}% FROM chapter pulled from current \part + 1
--% Range delimiter
\ifcsname r@part-\number\numexpr\arabic{part}+1\endcsname
\getrefnumber{part-\inteval{\arabic{part}+1}}% TO chapter pulled from next \part
\else
\getrefnumber{part-end}% At end-of-document chapter number
\fi]
\makeatletter
\NewCommandCopy{\oldpart}{\part}
\RenewDocumentCommand{\part}{s o m}{%
\IfBooleanTF{#1}
{\oldpart*{#3}}% \part*[.]{..}
{\IfValueTF{#2}
{\oldpart[#2]{#3}}% \part[.]{..}
{\oldpart{#3}}% \part{..}
{\renewcommand{\@currentlabel}{\arabic{chapter}}\label{part-\arabic{part}}}% Store chapter number after issuing \part
}
}
\AtEndDocument{%
\renewcommand{\@currentlabel}{\thechapter}%
\label{part-end}% Insert end-of-document chapter number capture
}

这是一种可能的方法，您需要两次编译才能获得正确的结果。
\documentclass{book}
\usepackage{titlesec}
\titleformat{\part}[display]
{\centering\huge}
{\partname~\thepart}
{0pt}
{}

\newcommand*\savechapnum[2]{

编辑
使用以下代码可以更改章节范围的格式。该宏\chaprangeformat接受三个参数。第一个是当前部分中没有章节时的格式，第二个是只有一个章节时的格式，第二个参数#1表示此章节编号，第三个是其他格式，#1表示部分中的第一个章节，#2最后一个。
以下有两个示例：
