scrbook 类文档页眉中章节标题第二行的缩进

Question

我有一个自定义scrbook类文档和一个很长的章节标题，在页眉中打印标题时会产生换行符。第二行的第一个字符与第一行的第一个字符不对齐；而是与章节号对齐。我该如何修复这个问题？

\documentclass{test}
\usepackage[utf8]{inputenc}

\usepackage{hyperref}

\begin{document}

\chapter[A Bcdefg hijklmnop qrstuvwx yz abc defghij klmnopq rs tuv wxyzab cdef Ghijklmnop Qrstuvwx yzabcdefg]{\texorpdfstring{A Bcdefg hijklmnop qrstuvwx yz abc defghij klmnopq\newline rs tuv wxyzab cdef Ghijklmnop Qrstuvwx yzabcdefg}{A Bcdefg hijklmnop qrstuvwx yz abc defghij klmnopq rs tuv wxyzab cdef Ghijklmnop Qrstuvwx yzabcdefg}}

\newpage

测试.cls：

\renewcommand{\chaptermark}[1]{\markboth{\textsc{\thechapter~#1}}{}}
\renewcommand{\sectionmark}[1]{\markright{\textsl{\thesection~#1}}}

我建议在标题中使用简短的标题：

\documentclass[
  %a4paper,% default
  12pt,
  %twoside, openright,% default for scrbook
  BCOR=1.5cm,
  appendixprefix,
  %cleardoublepage=empty,% default
  numbers=noenddot,
  bibliography=totoc,
  headings=optiontoheadandtoc% <- added!
]{scrbook}

\usepackage[T1]{fontenc}
%\usepackage[utf8]{inputenc}% only needed with older TeX Distributions
\usepackage{lmodern}

\usepackage[automark,headsepline]{scrlayer-scrpage}
\clearpairofpagestyles
\ofoot*{\pagemark}
\ohead{\headmark}

\renewcommand{\chaptermark}[1]{\markboth{\textsc{\thechapter~#1}}{}}
\renewcommand{\sectionmark}[1]{\markright{\textsl{\thesection~#1}}}

\usepackage{hyperref}

\begin{document}
\tableofcontents
\chapter[
  tocentry={A Bcdefg hijklmnop qrstuvwx yz abc defghij klmnopq rs tuv wxyzab cdef Ghijklmnop Qrstuvwx yzabcdefg},
  head={short title for header}
]{A Bcdefg hijklmnop qrstuvwx yz abc defghij klmnopq\newline rs tuv wxyzab cdef Ghijklmnop Qrstuvwx yzabcdefg}

\clearpage
.
\end{document}

补充说明：

• 不要inputenc在类文件中加载包。如果确实需要包，则在文档文件本身中加载它。
• 如果有 KOMA-Script 类可用，那么scrlayer-scrpage也会安装包。

如果您确实需要标题中章节标题的长版本：

\documentclass[
  %a4paper,% default
  12pt,
  %twoside, openright,% default for scrbook
  BCOR=1.5cm,
  appendixprefix,
  %cleardoublepage=empty,% default
  numbers=noenddot,
  bibliography=totoc
]{scrbook}

\usepackage[T1]{fontenc}
%\usepackage[utf8]{inputenc}% only needed with older TeX Distributions
\usepackage{lmodern}

\usepackage[automark,headsepline]{scrlayer-scrpage}
\clearpairofpagestyles
\ofoot*{\pagemark}
\ohead{\headmark}

\makeatletter% <- added
\renewcommand{\chaptermark}[1]{\markboth{\scshape\@hangfrom{\thechapter~}{#1}}{}}% <- changed
\renewcommand{\sectionmark}[1]{\markright{\slshape\@hangfrom{\thesection~}{#1}}}% <- changed
\makeatother% <- added

\usepackage{hyperref}

\KOMAoptions{headlines=2.1}% <-added
\recalctypearea% <- added

\begin{document}
\tableofcontents
\chapter
  [A Bcdefg hijklmnop qrstuvwx yz abc defghij klmnopq rs tuv wxyzab cdef Ghijklmnop Qrstuvwx yzabcdefg]
  {A Bcdefg hijklmnop qrstuvwx yz abc defghij klmnopq\newline rs tuv wxyzab cdef Ghijklmnop Qrstuvwx yzabcdefg}

\clearpage
.
\end{document}

请注意，您必须在文档的前言中为headlines或headheight后跟设置适当的值。\recalctypearea
