\chaptertitle 在 scrbook 和 scrlayer-scrpage 中不起作用

\chaptertitle 在 scrbook 和 scrlayer-scrpage 中不起作用

我需要让当前章节的标题出现在我的书的标题中。使用标准类,book我只需使用titlesec包和\chaptertitle

\documentclass{book}

\usepackage{titlesec}
\newpagestyle{main}{\sethead{}{\chaptername\ \thechapter: \chaptertitle}{}}
\pagestyle{main}

\usepackage{lipsum}

\begin{document}
    \chapter{Lorem Ipsum}
    \section{Foo}
    \lipsum[1-5]
    
    \section{Bar}
    \lipsum[6]
    \subsection{Baz}
    \lipsum[7-10]
\end{document}

scrbook但是,这是我第一次使用。我知道我可以使用 package 更改标头内容scrlayer-scrpage,但是当我尝试编译以下内容时

\documentclass{scrbook}

\usepackage{scrlayer-scrpage}
\lehead{}
\rohead{}
\chead{\chaptername~\thechapter: \chaptertitle}

\usepackage{lipsum}

\begin{document}
    \chapter{Lorem Ipsum}
    \section{Foo}
    \lipsum[1-5]
    
    \section{Bar}
    \lipsum[6]
    \subsection{Baz}
    \lipsum[7-10]
\end{document}

我收到两个错误:

l.19 \end
{document}
? h
The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

? 
[2]
! Undefined control sequence.
\sls@ps@scrheadings@odd@middle@head ...aptertitle 

l.19 \end{document}

? h
The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

?

如果我继续下去,我会得到一个带有标题但没有章节标题的文档:

标题仅包含“第 1 章:”

问题应该出在这里,\chaptertitle因为如果我删除它,文档就会被正确编译。我可能忽略了一些显而易见的东西,但我不明白什么

你有什么建议吗?

答案1

scrbook必须重新定义\chaptermarkformat

\renewcommand*\chaptermarkformat{\chaptername~\thechapter:\enspace}

然后你可以使用\chead{\leftmark}

例子:

\documentclass{scrbook}
\renewcommand*\chaptermarkformat{\chaptername~\thechapter:\enspace}
\usepackage[automark]{scrlayer-scrpage}% <- option automark added
\ohead{}
\chead{\leftmark}
\usepackage{lipsum}

\begin{document}
\chapter{Lorem Ipsum}
\section{Foo}
\lipsum[1-5]

\section{Bar}
\lipsum[6]
\subsection{Baz}
\lipsum[7-10]
\end{document}
