tufte_book：防止目录中的页码和作者（Rmarkdown）

Question

好吧，我一开始没有注意到这个问题，因为它只出现在第 4 页。在学习了一些 Rmarkdown 并弄乱了 .cls 文件后，我想我找到了这个问题。首先修复，然后解释。

修复

问题在于toc: true选项的使用。目录需要在范围内\frontmatter，而此选项似乎可以防止这种情况发生。请改用以下内容：

---
title: ".Rmd tufte_book page numbering"
author: "Author"
documentclass: tufte
output: 
  tufte::tufte_book:
    number_sections: true
---
\frontmatter
\tableofcontents

# Preface

\mainmatter

# Chapter
# Chapter
# Chapter
# Chapter
# Chapter
# Chapter
# Chapter
# Chapter
# Chapter
# Chapter
# Chapter

说明

Tufte LaTeX 类中的标题设置在tufte-common.def定义文件相关代码从1438行开始到1481行结束：

% Sets up the running heads and folios.

\RequirePackage{fancyhdr}

% Set the default page style to 'fancy'
\pagestyle{fancy}

% Set the header/footer width to be the body text block plus the margin
% note area.
\AtBeginDocument{%
  \ifthenelse{\boolean{@tufte@symmetric}}
    {\fancyhfoffset[LE,RO]{\@tufte@overhang}}
    {\fancyhfoffset[RE,RO]{\@tufte@overhang}}
}

% The running heads/feet don't have rules
\renewcommand{\headrulewidth}{0pt}
\renewcommand{\footrulewidth}{0pt}

% The 'fancy' page style is the default style for all pages.
\fancyhf{} % clear header and footer fields
\ifthenelse{\boolean{@tufte@twoside}}
  {\fancyhead[LE]{\thepage\quad\smallcaps{\newlinetospace{\plainauthor}}}%
    \fancyhead[RO]{\smallcaps{\newlinetospace{\plaintitle}}\quad\thepage}}
  {\fancyhead[RE,RO]{\smallcaps{\newlinetospace{\plaintitle}}\quad\thepage}}


% The `plain' page style is used on chapter opening pages.
% In Tufte's /Beautiful Evidence/ he never puts page numbers at the
% bottom of pages -- the folios are unexpressed.
\fancypagestyle{plain}{
  \fancyhf{} % clear header and footer fields
  % Uncomment the following five lines of code if you want the opening page
  % of the chapter to express the folio in the lower outside corner.
  %\ifthenelse{\boolean{@tufte@twoside}}
  %  {\fancyfoot[LE,RO]{\thepage}}
  %  {\fancyfoot[RE,RO]{\thepage}}
}

% The `empty' page style suppresses all headers and footers.
% It's used on title pages and `intentionally blank' pages.
\fancypagestyle{empty}{
  \fancyhf{} % clear header and footer fields
}

正是这一行导致了不良行为：

{\fancyhead[LE]{\thepage\quad\smallcaps{\newlinetospace{\plainauthor}}}%

和命令会进行修改，删除前文中的部分，并\frontmatter在主内容中替换为：\mainmattertufte-book.cls\plainauthor\plainauthor\plaintitle

% The front matter in Tufte's /Beautiful Evidence/ contains everything up
% to the opening page of Chapter 1.  The running heads, when they appear,
% contain only the (arabic) page number in the outside corner.
%\newif\if@mainmatter \@mainmattertrue
\renewcommand\frontmatter{%
  \if@openright%
    \cleardoublepage%
  \else%
    \clearpage%
  \fi%
  \@mainmatterfalse%
  \pagenumbering{arabic}%
  %\pagestyle{plain}%
  \fancyhf{}%
  \ifthenelse{\boolean{@tufte@twoside}}%
    {\fancyhead[LE,RO]{\thepage}}%
    {\fancyhead[RE,RO]{\thepage}}%
}


% The main matter in Tufte's /Beautiful Evidence/ doesn't restart the page
% numbering---it continues where it left off in the front matter.
\renewcommand\mainmatter{
  \if@openright%
    \cleardoublepage%
  \else%
    \clearpage%
  \fi%
  \@mainmattertrue%
  \fancyhf{}%
  \ifthenelse{\boolean{@tufte@twoside}}%
    {% two-side
      \renewcommand{\chaptermark}[1]{\markboth{##1}{}}%
      \fancyhead[LE]{\thepage\quad\smallcaps{\newlinetospace{\plaintitle}}}% book title
      \fancyhead[RO]{\smallcaps{\newlinetospace{\leftmark}}\quad\thepage}% chapter title
    }%
    {% one-side
      \fancyhead[RE,RO]{\smallcaps{\newlinetospace{\plaintitle}}\quad\thepage}% book title
    }%
}

此代码重新定义了标题以删除作者姓名并将其替换为正文中的标题，并仅打印前言中的页码（即，它似乎做了您想要的事情）。

问题是\frontmatter在 pancdoc 生成目录之前没有调用。通过删除选项并\tableofcontents在适当的位置（之后\frontmatter）手动插入命令，您可以获得指定的正确标题tufte-book.cls。
