在 Beamer 中调整书签编号

Question

我正在处理第一个回复这里。但是，我的代码\section*{Intro}在开头包含一个，因此书签编号会加一（即，我需要第一个书签编号为 1）。我该如何减少这个！

这是我的代码

\documentclass{beamer}
\hypersetup{
  bookmarksnumbered=true
}
\setcounter{tocdepth}{4}

% get numbering in section bookmarks
\usepackage{etoolbox}
\usepackage{bookmark}
\makeatletter
\patchcmd{\beamer@section}%
    {\Hy@writebookmark{\the\c@section}{\secname}}%
    {\Hy@writebookmark{\the\c@section}{\numberline{\thesection}\secname}}%
    {}{\errmessage{failed to patch}}
\patchcmd{\beamer@subsection}%
   {\Hy@writebookmark{\the\c@subsection}{#2}}%
    {\Hy@writebookmark{\the\c@subsection}{\numberline{\thesection.\thesubsection}#2}}%
    {}{\errmessage{failed to patch}}
\patchcmd{\beamer@subsubsection}%
    {\Hy@writebookmark{\the\c@subsubsection}{#2}}%
    {\Hy@writebookmark{\the\c@subsubsection}{\numberline{\thesection.\thesubsection.\thesubsubsection}#2}}%
    {}{\errmessage{failed to patch}}
\makeatother


\begin{document}

\section*{Intro}

\section{section}

\begin{frame}
\end{frame}

\subsection{subsection}
\begin{frame}
\end{frame}

\subsubsection{subsubsection}
\begin{frame}

\subsection{subsection}

\end{frame}

\subsubsection{subsubsection}

\end{frame}
\end{document}

Answer 1

不幸的是，beamer它并不真正支持编号/未编号部分。不过可以对其进行修补以提供此功能的一些尝试。

在这里，我创建了一个名为 的新计数器realsection，它只会在非星号部分增加，而不会在星号部分增加（正如您所注意到的，section在 中两者都增加beamer）。使用新计数器应该比尝试调整现有计数器更可靠。此解决方案还具有不必记住手动在计数器上加一等优点。

\documentclass{beamer}
\hypersetup{
  bookmarksnumbered=true
}
\setcounter{tocdepth}{4}

% get numbering in section bookmarks
\usepackage{etoolbox}
\usepackage{bookmark}
\makeatletter

\newcounter{realsection}
\newif\ifrealsection
\long\def\beamer@@ssection*#1{\realsectionfalse\beamer@section[{#1}]{}}
\long\def\beamer@@@section#1{\realsectiontrue\beamer@section[{#1}]{#1}}

\patchcmd{\beamer@section}%
    {\refstepcounter{section}}%
    {\ifrealsection\refstepcounter{realsection}\fi\refstepcounter{section}}%
    {}{\errmessage{failed to patch}}

\patchcmd{\beamer@section}%
    {\Hy@writebookmark{\the\c@section}{\secname}}%
    {\Hy@writebookmark{\the\c@section}{\numberline{\therealsection}\secname}}%
    {}{\errmessage{failed to patch}}
\patchcmd{\beamer@subsection}%
   {\Hy@writebookmark{\the\c@subsection}{#2}}%
    {\Hy@writebookmark{\the\c@subsection}{\numberline{\therealsection.\thesubsection}#2}}%
    {}{\errmessage{failed to patch}}
\patchcmd{\beamer@subsubsection}%
    {\Hy@writebookmark{\the\c@subsubsection}{#2}}%
    {\Hy@writebookmark{\the\c@subsubsection}{\numberline{\therealsection.\thesubsection.\thesubsubsection}#2}}%
    {}{\errmessage{failed to patch}}
\makeatother

Answer 2

根据评论@karlkoeller，我想知道以下放置是否\addtocounter{section}{-1}会产生预期的结果

\documentclass{beamer}
\hypersetup{
  bookmarksnumbered=true
}
\setcounter{tocdepth}{4}

% get numbering in section bookmarks
\usepackage{etoolbox}
\usepackage{bookmark}
\makeatletter
\patchcmd{\beamer@section}%
    {\Hy@writebookmark{\the\c@section}{\secname}}%
    {\Hy@writebookmark{\the\c@section}{\numberline{\thesection}\secname}}%
    {}{\errmessage{failed to patch}}
\patchcmd{\beamer@subsection}%
   {\Hy@writebookmark{\the\c@subsection}{#2}}%
    {\Hy@writebookmark{\the\c@subsection}{\numberline{\thesection.\thesubsection}#2}}%
    {}{\errmessage{failed to patch}}
\patchcmd{\beamer@subsubsection}%
    {\Hy@writebookmark{\the\c@subsubsection}{#2}}%
    {\Hy@writebookmark{\the\c@subsubsection}{\numberline{\thesection.\thesubsection.\thesubsubsection}#2}}%
    {}{\errmessage{failed to patch}}
\makeatother


\begin{document}

\addtocounter{section}{-2}
\section*{Intro}
\begin{frame}
    intro
\end{frame}

\addtocounter{section}{+1}
\section{section}

\begin{frame}
    section1
\end{frame}

\subsection{subsection}
\begin{frame}
    section1.1
\end{frame}

\subsubsection{subsubsection}
\begin{frame}
    section1.1.1
\end{frame}

\section{section}
\begin{frame}
    section2
\end{frame}

\subsection{subsection}
\begin{frame}
    section2.1
\end{frame}

\subsubsection{subsubsection}
\begin{frame}
    section2.1.1
