我对 \markboth \leftmark \rightmark 等感到困惑！有简单的解释吗？

Question

我的问题来自于我很难理解 fancyhd 或 titleps 的 readmes 中关于标记的英文解释，因此无法修改标题。我不明白这些标记以及 extramarks 选项引入的标记背后的业务。

从我的 readme 中得知，该titleps软件包有一个带星号的标记版本，当第一个小节与小节标题位于同一页时，可以正确地考虑它。这解决了 LaTeX 的 bug（我也没有完全理解）。

我没有偏爱哪个包，但 titleps 让我更接近我想要的。在 MWE 之前，我的愿望是

\documentclass[twoside, a4paper, 11pt]{article}

在每一页上：

• 左上角 =\thesection--sectiontitle

• 顶部中间 =\thepage

• 右上角 =\thesubsection--subsectiontitle 但是当我们更改该部分时会出现问题，请参见下文。

• 底部中间 =\the page

对于目录和参考书目，我只希望在左上角有“目录”，在右上角有页面。

使用直接从自述文件中复制的 MWE，

\documentclass[twoside, a4paper, 11pt]{article}
\usepackage[topmarks, extramarks]{titleps}
\settitlemarks*{section,subsection}


\newpagestyle{funny}{
\setfoot{\toptitlemarks Top is \thesubsection}
{\firsttitlemarks First is \thesubsection}
{\bottitlemarks Bot is \thesubsection}
\sethead{\firstextramarks{section}\thesection---\sectiontitle}
{\firstextramarks{subsection}\thesubsection---\subsectiontitle}
{\thepage}
}


\pagestyle{funny}



\usepackage{lipsum}

\lipsum[1-3]



\subsection{second subsetion of the third section}

\lipsum[1-3]
\subsection{third subsetion of the third section}
\lipsum[1-11]






\end{document}

但是，目录的标题存在问题，在第 6 页上，我们可以看到标题对于章节来说是足够的，但对于子章节来说却不够，因为它显示的是第一章节的第三子章节！应该是，

top left= section two

top middle= the page

top right=blank

Answer 1

我之前的评论只起到了一点帮助。这主要是因为你定义的页面样式，但也因为\subsectionmark{}会自动“步进”计数器。

我会这么做：

1. 当页面包含部分而没有子部分时，添加额外的页面样式；即，

   \newpagestyle{nosubsec}{%
     \setfoot
       {\toptitlemarks Top is \thesubsection}%
       {}%
       {\bottitlemarks Bot is \thesubsection}%
     \sethead
       {\firstextramarks{section}\thesection---\sectiontitle}%
       {}%
       {\thepage}%
   }
   

2. 修补\section和\subsection命令以自动使用它们。也就是说，make \sectionemit the\pagestyle{nosubsec}然后 make \subsectionemit \pagestyle{funny}：

   \usepackage{etoolbox}
   \pretocmd{\section}{\pagestyle{nosubsec}}{}{}
   \pretocmd{\subsection}{\pagestyle{funny}}{}{}
   

您的示例文档将如下所示：

\documentclass[twoside, a4paper, 11pt]{article}
\usepackage{etoolbox}
\usepackage[topmarks, extramarks]{titleps}
\settitlemarks*{section,subsection}

\newpagestyle{funny}{%
  \setfoot
    {\toptitlemarks Top is \thesubsection}%
    {\firsttitlemarks First is \thesubsection}%
    {\bottitlemarks Bot is \thesubsection}%
  \sethead
    {\firstextramarks{section}\thesection---\sectiontitle}%
    {\firstextramarks{subsection}\thesubsection---\subsectiontitle}%
    {\thepage}%
}
\pagestyle{funny}

\newpagestyle{nosubsec}{%
  \setfoot
    {\toptitlemarks Top is \thesubsection}%
    {}%
    {\bottitlemarks Bot is \thesubsection}%
  \sethead
    {\firstextramarks{section}\thesection---\sectiontitle}%
    {}%
    {\thepage}%
}

\pretocmd{\section}{\pagestyle{nosubsec}}{}{}
\pretocmd{\subsection}{\pagestyle{funny}}{}{}

\usepackage{lipsum}

不过，正如我之前所说，整个“标记”系统是一项棘手的工作，并且可以相对容易地欺骗 LaTeX 做一些你不想要的事情......
