在回忆录类中显示章节标题下方的章节标签和编号

Question

我正在设计一本带有回忆录类的书。章节样式应类似于新高德书籍，章节标签和编号应在章节标题后的新行中显示，即

关于文艺复兴主题的论文

第1章

我找不到任何预定义或修改过的样式来实现这一点。垂直移动章节标签可能不是一个好主意，因为标题可能很长，然后会重叠。如何编码？

我的结构如下：

\documentclass[a4paper, 12pt, onecolumn, openany]{memoir}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}    
\usepackage[ngerman]{babel}
\usepackage{fontspec}

\renewcommand{\chapnamefont}{\centering\LARGE\normalfont} 
\renewcommand{\chapnumfont}{\centering\LARGE\normalfont} 
\renewcommand\chaptitlefont{\centering\LARGE\normalfont}
\renewcommand\secheadstyle{\centering\Large\normalfont\noindent}

\addto\captionsngerman{\renewcommand{\chaptername}{Caput}}

\setmainfont{EB Garamond}

\begin{document}

   \chapter{A treatise on some renaissance topic}

\end{document}

Answer 1

inverse以下是使用包含字体的章节样式的一种选项：

代码：

\documentclass{memoir}
\usepackage[ngerman]{babel}
\usepackage{fontspec}

\addto\captionsngerman{\renewcommand{\chaptername}{Caput}}

\setmainfont{EB Garamond}

\makeatletter
\newlength\betweennametitle% to control separation between chapter title and name 
\setlength\betweennametitle{-60pt}

\makechapterstyle{inverse}{
  \chapterstyle{default}
  \renewcommand{\chapnamefont}{\LARGE\normalfont} 
  \renewcommand{\chapnumfont}{\LARGE\normalfont} 
  \renewcommand\chaptitlefont{\centering\LARGE\normalfont}
  \setlength{\beforechapskip}{10pt}
  \setlength{\afterchapskip}{\dimexpr-\betweennametitle+20pt\relax}
  \setlength{\midchapskip}{0pt}
  \def\printchaptername{}
  \renewcommand*{\printchapternonum}{%
    \raisebox{\betweennametitle}[0pt][0pt]{%
      \vphantom{{\chapnamefont\@chapapp}{\chapnumfont\thechapter}}%
    }\afterchapternum\vskip\onelineskip\vskip-\topskip%
  }
  \renewcommand*{\printchapternum}{%
    \raisebox{\betweennametitle}[0pt][0pt]{%
      \makebox[\textwidth]{{\chapnamefont\@chapapp}\chapternamenum{\chapnumfont\thechapter}}%
    }%
  }%
}
\makeatother

\chapterstyle{inverse}

\begin{document}

\chapter{A test numbered chapter}
Some test text

\end{document}

请不要加载带有 fontspec` 的fontenc字体inputenc。
