如何生成替代阅读顺序的目录

我在文档主体中有一个结构如下的工作：

1. Main topic 1
  1.1. Subject 1
  1.2. Subject 2
  1.3. Subject 3
2. Main topic 2
  2.1. Subject 1
  2.2. Subject 2
  2.3. Subject 3
3. Main topic 3
  3.1. Subject 1
  3.2. Subject 2
  3.3. Subject 3

我想要生成两种类型的目录：一种是传统的（自然顺序），一种是替代阅读顺序，如下所示：

Subject 1 
  Main topic 1
  Main topic 2
  Main topic 3
Subject 2
  Main topic 1
  Main topic 2
  Main topic 3
Subject 3
  Main topic 1
  Main topic 2
  Main topic 3

此生成必须完全自动化，并带有页码和hyperref链接。

我该怎么做？有没有什么软件包可以帮助我？我也愿意使用自定义宏。

答案1

这是再次读取的版本，.toc并进行了修改\contentsline，以便提取存储到的的信息.toc。

我利用了expl3功能来将信息分组gtoc（即分组目录），这是一个需要改进的非常初步的版本。

宏\extracttocinformation是重新排序的形式ToC

简而言之，根据实际用例，这有点复杂。

您可以使用以下内容创建“主题目录”：

在此处输入图片描述

\documentclass{article}

\usepackage{lipsum,pgffor}% Just for this example
\usepackage{etoolbox,refcount}
\usepackage{hyperref}

\makeatletter
\newcommand{\maintopic}[1]{%
  \edef\maintopictitle{Main topic #1}% Caption main topic name/title
  \section{\maintopictitle}% Set main topic in document
}

\newcounter{subjectnum}
\newcommand{\subject}[1]{%
  \subsection{Subject #1}% Set subject in document
  \stepcounter{subjectnum}% Step subjectnum counter; used for internal reference purposes only
  \label{subject-\thesubjectnum}% Set an internal link (for page extraction)
  \xifinlistcs{#1}{subject_list}{}{%
    \listcsxadd{subject_list}{#1}% Add subject to subject_list list if not already in it
  }%
  \edef\maintopicHref{subsection.\theHsubsection}% Capture hyperref link
  \edef\maintopicpageref{\getpagerefnumber{subject-\thesubjectnum}}% Capture page number
  % Store main topic title, page and hyperref link in subject-specific list
  \listcsxadd{subject_#1_topic}{\maintopictitle @@@ \maintopicpageref @@@ \maintopicHref}%
}

\newcommand{\reorderlist}[1]{%
  \addtocontents{cot}{% Set subject entry in the .cot
    \protect\contentsline{section}{Subject #1}{}{}
  }
  \forlistcsloop{\cotmaintopic}{subject_#1_topic}% Process subject-specific list
}
\def\topicname#1@@@ #2@@@ #3...{#1}% Extract main topic name/title
\def\topicpage#1@@@ #2@@@ #3...{#2}% Extract main topic page
\def\topicHref#1@@@ #2@@@ #3...{#3}% Extract main topic hyperref link
\newcommand{\cotmaintopic}[1]{%
  \edef\x{\noexpand\addtocontents{cot}{%
    \noexpand\protect\noexpand\contentsline{subsection}
      {\topicname#1...}% Main topic name/title
      {\topicpage#1...}% Main topic page
      {\topicHref#1...}% Main topic hyperref link
  }}\x% Set main topic entry in .cot
}
\AtEndDocument{%
  \forlistcsloop{\reorderlist}{subject_list}% Process subject_list list
}
\let\subjecttoc\tableofcontents% \subjecttoc is similar to \tableofcontents
% \patchcmd{<cmd>}{<search>}{<replace>}{<true>}{<false>}
\patchcmd{\subjecttoc}{{toc}}{{cot}}{}{}% ...just change .toc to .cot
\makeatother

\begin{document}

\subjecttoc

\sloppy% Just for this example
% Create a mock document with 5 topics and 7 subjects under each
\foreach \topicnum in {1,...,5} {
  \maintopic{\topicnum}\lipsum[1-5]
  \foreach \subjectnum in {One, Two, Three, Four, Five, Six, Seven} {
    \subject{\subjectnum}\lipsum[6-10]
  }
}

\end{document}

该解决方案背后的原理是积累一个主题列表。并且，对于每个主题，您创建一个列表，其中包含（1）主要主题标题，（2）主题的页码和（3）hyperref-与主题兼容的引用。

在文档的末尾，将针对每个可能的主题处理列表，并将每个条目写入目录（使用.cot文件扩展名）。您可以调用\subjecttoc来创建“主题目录”和/或\tableofcontents常规目录。

每个都\maintopic被视为\section，而\subjects 是\subsection（如果需要，可以更改）。这些角色在 中被反转，\subjecttoc并且部分编号被删除（因为反转后没有意义）。
