附录：Hyperref 与目录不匹配

Question

在 Adob​​e Acrobat Reader 中，“附录”与各个附录章节处于同一级别。是否可以更改 Adob​​e 表示，使其看起来像目录中的样子（= 将第一章和第二章置于“附录”之下）？

平均能量损失：

\documentclass[a4paper,12pt,parskip=half]{report}

\usepackage{hyperref}

\usepackage[toc,page]{appendix}
\renewcommand\appendixtocname{Appendices}
\renewcommand\appendixpagename{Appendices}
\let\appendixpagenameorig\appendixpagename

\begin{document}

  \tableofcontents

  \begin{appendices}
    \addtocontents{toc}{\protect\setcounter{tocdepth}{1}}
    \makeatletter
    \addtocontents{toc}{%
      \begingroup
      \let\protect\l@chapter\protect\l@section
      \let\protect\l@section\protect\l@subsection
    }
    \makeatother

    \chapter{Chapter One}
    \chapter{Chapter Two} 
  \end{appendices}
\end{document}

Answer 1

整个麻烦是因为\chapter在很多情况下使用了附录作为章节，但可以通过toclevel@chapter增加一来改变书签级别。

\documentclass[a4paper,12pt,parskip=half]{report}

\usepackage[toc,page]{appendix}
\usepackage{etoolbox}    
\usepackage[bookmarksopen,bookmarksopenlevel=2]{hyperref}


\makeatletter

\apptocmd{\appendices}{%
  \renewcommand{\toclevel@chapter}{1}% Shift the chapter level to 1 ('section')
  \renewcommand{\toclevel@section}{\the\numexpr\toclevel@chapter+1}
  \renewcommand{\toclevel@subsection}{\the\numexpr\toclevel@section+1}
    \addtocontents{toc}{\protect\setcounter{tocdepth}{1}}
    \addtocontents{toc}{%
       \begingroup
       \let\protect\l@chapter\protect\l@section
       \let\protect\l@section\protect\l@subsection
     }%
   }{}{}


\AfterEndEnvironment{appendices}{%
  \addtocontents{toc}{\endgroup}%  Close the group
}

\makeatother

\renewcommand\appendixtocname{Appendices}
\renewcommand\appendixpagename{Appendices}
\let\appendixpagenameorig\appendixpagename

\begin{document}

  \tableofcontents

  \chapter{Foo}

  \begin{appendices}


    \chapter{Chapter One}
    \section{Foo section}
    \chapter{Chapter Two} 
  \end{appendices}
\end{document}
