编辑书籍：同一章节中有多个作者，且有同一目录

Question

我想在章节标题前添加作者姓名。我使用以下内容：

\documentclass{book}
\usepackage{titlesec}
\usepackage{titletoc}
\usepackage{lipsum}% just to generate some text

\makeatletter
  \newcommand*\l@authors{\@dottedtocline{1}{0pt}{0pt}}
\makeatother
\newcommand\chapaut[1]{%
  \addcontentsline{toc}{authors}{#1}%
  {\bfseries#1}\vskip35pt}

\titleformat{\chapter}[display]
  {\normalfont\huge\bfseries}{}{20pt}{\Huge}[\addvspace{5pt}]
\titlespacing*{\chapter}
  {0pt}{10pt}{0pt}
\titlecontents{chapter}
  [0pt]{\addvspace{10pt}}{\bfseries}{\bfseries}{}

\begin{document}
\tableofcontents

\chapter{Test chapter one}
\chapaut{The name of the first author, The name of second author and The name of the third author}
\lipsum[1-20]

\chapter{Test chapter two}
\chapaut{The First author and The second author}
\lipsum[1-20]

\end{document}

我想用 chapaut 更改章节，因此它看起来像：

另外，在目录中：

Answer 1

如果我理解正确的话，你想实现两件事：

在目录中，您希望将该章节的作者列在章节标题之前。

当打印章节时，您还希望在章节标题前显示作者。

我认为这可能会有所帮助，但我确实相信有比这更好的方法，尤其是对于 ToC。

在文本中将作者打印在章节标题上方的另一种方法可能是更改 的定义\chapter，但有时更改某些命令的定义可能会产生无法预料的副作用，因此只有在您知道自己在做什么时才这样做。这个问题可能会引起人们的兴趣：在同一页上开始新的篇章。

编辑：非常长的章节标题，跨越目录中的多行，现在将在每一行缩进，而不仅仅是第一行。

\documentclass{book}
\usepackage{titletoc}
\usepackage{lipsum}% just to generate some text

% This part changes how chapters are displayed in the Table of COntents
\titlecontents{chapter}
  [0pt]% Left margin, optional
  {}% Code insertet above
  {\bfseries}% Numbered-entryformat
  {\bfseries}% Numberless-format
  {\contentspage\vskip1.5ex} %Below code, here: add dotfill and pagenumber for entry, and some vertical space between entries

% Custom command to keep the author on the same page of chaptertitle, and above it.  
\newcommand{\chapterAndAuthor}[2]{%
 % Takes the following input

        \vspace{-3\baselineskip}
        % Add an entry to the Table of Contents, with the name of the author in italics and the chapter title
        \addcontentsline{toc}{chapter}{{\normalfont\itshape #1}\vspace{1ex}\newline%
        %To make long chapter titles spanning multiple lines indent on each line, a \parbox is created. This is siimply a box holding a wrapped paragraph at a certain length. Also, we need to move the dotfill here.
        \hspace*{1em}\protect{\parbox[b]{\textwidth}{#2 \dotfill}}}
        % Print the chapter
        \chapter*{#2}
    \end{minipage}
    }
