1.用例-将布局与内容分离：

tag-icon • tag-icon header-footer memoir chapters xpatch page
1.用例-将布局与内容分离：

密切相关：
-为章节标题和内容页创建单独的页脚和页眉？

1.用例-将布局与内容分离：

内容作者将通过网络门户提供 TeX 内容，其中可能包括\chapter{Chapter Title}脚注、数学、图像和其他 TeX 语法。

然而，通常情况下，这些作者可能会错误地指定默认值chapter title page和样式，或者chapter content page受到损坏通过其他进口（、、\input等）\include\usepackage

澄清：AChapter Title Page是章节的第一页。Chapter Content Pages是章节的其余内容页。这与目录无关，但不应影响目录。

2.问题：

使用回忆录、书籍或其他文档类别，是否可以执行与相关问题相同的操作\xpatchcmd？

是否可以仅定义和应用自定义类一次来影响整个文档的所有Chapter Title Pages内容，而无需像类似问题中所见的那样重复所有代码？Chapter Content Pages

目标：

  1. 能够分别为章节标题页和章节内容页定义页眉和页脚（当前答案无法做到这一点）。
  2. 最终为书中的每个部分提供单独的自定义样式（而不必担心默认样式被破坏）。
  3. 减少代码重复。
  4. 可以覆盖导入文档中不受欢迎的定制。
  5. 将\xpatchcmd任何其他修补命令列入黑名单并禁止使用。

3.代码示例：

\documentclass{memoir}

\usepackage{lipsum}

\makepagestyle{chapter}
    \makeheadrule{chapter}{\textwidth}{\normalrulethickness}
    \makefootrule{chapter}{\textwidth}{\normalrulethickness}{\footruleskip}
    \makeoddhead {chapter}{left header}{odd header}{right header}
    \makeoddfoot {chapter}{left footer}{odd footer}{right footer}
    % ***** Added in Even Page Headers and Footers to show on Chapter Content Pages
    \makeevenhead {chapter}{left header}{even header}{right header}
    \makeevenfoot {chapter}{left footer}{even footer}{right footer}


    \makepagestyle{alternate}
    \makeheadrule{alternate}{\textwidth}{\normalrulethickness}
    \makefootrule{alternate}{\textwidth}{\normalrulethickness}{\footruleskip}

    \makeevenhead {alternate}{left header}{alternate even header}{right header}

\xpatchcmd（从xpatch）与其对应物\patchcmd（来自etoolbox)：

\xpatchcmd{<cmd>}{<search>}{<replace>}{<success>}{<failure>}

\xpatchcmd搜索<search>in<cmd>并将其替换为<replace>。如果此搜索和替换成功，则执行<success>，否则执行<failure>。在您的代码示例中（删除注释后），

\xpatchcmd{\chapter}{\thispagestyle{chapter}}{}{}{}

搜索\thispagestyle{chapter}内部\chapter并将其替换为空。为简洁起见，<success>和<failure>分支也留空。实际上，上述命令会\thispagestyle{chapter}从中删除\chapter。

其次，你混淆\chapterstyle了\pagestyle。它们是不同的。章节样式（使用 定义\makechapterstyle）与 的调用一起使用\chapterstyle，并定义设置章节标题的方式，而不是章节页眉/页脚。后者称为页样式是通过（仅适用于当前页面）或（适用于从当前页面开始的页面）创建的\makepagestyle，并通过其使用/设置。\thispagestyle\pagestyle

以下是veelo 章节风格，例如：

在此处输入图片描述

% ...
\setcounter{chapter}{3}% Just for this example
\chapterstyle{veelo}
\chapter{Demonstration of the veelo \\ chapter style}
\sloppy\lipsum
%...

标题 - Chapter 4- 和标题 - Demonstration of the veelo \\ chapter style- 的设置方式已经改变，但页风格依旧chapter。

以下是应用ChapterPage 页样式到第一页\chapter下madsen 章节风格：

在此处输入图片描述

\documentclass{memoir}

\usepackage{lipsum,graphicx}

\makepagestyle{ChapterPage}
\makeheadrule{ChapterPage}{\textwidth}{\normalrulethickness}
\makefootrule{ChapterPage}{\textwidth}{\normalrulethickness}{\footruleskip}
\makeoddhead {ChapterPage}{left header}{centre header}{right header}
\makeoddfoot {ChapterPage}{left footer}{centre header}{right header}

\begin{document}

\tableofcontents

\clearpage
\copypagestyle{chapter}{ChapterPage}
\setcounter{chapter}{3}% Just for this example
\chapterstyle{madsen}
\chapter{Demonstration of the madsen \\ chapter style}
\sloppy\lipsum

\end{document}

\chapter默认情况下，给出第一页\thispagestyle{chapter}（参见memoir 文档， 部分7.2 页面样式）并且chapter页面样式是副本 - 实际上是别名- plain（参见章节7.3 制作页眉和页脚）。

首先，您必须完整地创建chapter页面样式，可以采用全新的样式（通过\makepagestyle{chapter}），也可以复制其他样式（如\copypagestyle{chapter}）。

然后您可以更改样式以满足您的需要：

\makepagestyle{chapter}% Officially create the chapter page style
\makeheadrule{chapter}{<width>}{<thickness>}% Header rule specification
\makefootrule{chapter}{<width>}{<thickness>}{<skip>}% Footer rule specification
\makeevenhead{chapter}{<left>}{<centre>}{<right>}% Even header
\makeoddhead {chapter}{<left>}{<centre>}{<right>}% Odd header
\makeevenfoot{chapter}{<left>}{<centre>}{<right>}% Even footer
\makeoddfoot {chapter}{<left>}{<centre>}{<right>}% Odd footer

这是一个完整的最小示例，重点介绍了该过程：

在此处输入图片描述

\documentclass{memoir}

\usepackage{lipsum}

% This creates (and overrides) the chapter page style - set on the 
% first page of a \chapter
\makepagestyle{chapter}
\makeheadrule{chapter}{\textwidth}{\normalrulethickness}
\makefootrule{chapter}{\textwidth}{\normalrulethickness}{\footruleskip}
\makeoddhead {chapter}{left header}{chapter odd header}{right header}
\makeoddfoot {chapter}{left footer}{chapter odd footer}{right footer}
\makeevenhead{chapter}{left header}{chapter even header}{right header}
\makeevenfoot{chapter}{left footer}{chapter even footer}{right footer}

% This is everything else - set on "chapter content" pages
\makepagestyle{alternate}
\makeheadrule{alternate}{\textwidth}{\normalrulethickness}
\makefootrule{alternate}{\textwidth}{\normalrulethickness}{\footruleskip}
\makeoddhead {alternate}{left header}{alternate odd header}{right header}
\makeoddfoot {alternate}{left footer}{alternate odd footer}{right footer}
\makeevenhead{alternate}{left header}{alternate even header}{right header}
\makeevenfoot{alternate}{left footer}{alternate even footer}{right footer}

\pagestyle{alternate}

\begin{document}

\sloppy% Just for this example

\chapter{Non-Styled Chapter}
\chapterprecis{Ideally the only code would be the \texttt{\string\include} command.
  Authors will only have TeX code specific to their own content - with no knowledge of current styles, 
  \textit{etc.} There would be no ``\texttt{\string\pagestyle}'' commands in these \texttt{\string\include}-ed files.
  Here, chapter content pages have no custom headers and footers.}
\lipsum

\chapter{Test Chapter With required \texttt{\string\pagestyle} command}
\chapterprecis{Required to use inner Styling to get Headers and Footers.}
\lipsum

\chapterstyle{bianchi}
\chapter{Testing Bianchi Chapter Style}
\chapterprecis{Built in Chapter Styles have no impact on headers and footers.%

  corruption of default \texttt{\string\pagestyle\string{chapter\string}}}
