有条件生成文本块

2024-5-22 • tag-icon

在当前使用 xelatex、回忆录类的文档中，我的章节是诗歌评论块的汇编。请参阅附加代码。[粗体文本使用不同的语言，衬线文本是英文对应文本]

有没有办法分离诗句部分，当我编译时，文档只生成诗句列表，如果我更改 tex 序言中的标志，我就可以生成诗句和随附的评论文本块。


\documentclass[12pt]{memoir}
\usepackage{lipsum}
\usepackage{polyglossia} % the multilingual support package

\setromanfont[Ligatures=TeX]{Linux Libertine O}
\def\mverse{\ifhmode \par \fi
   \goodbreak \addvspace{3ex} \refstepcounter{section}
   \centerline{\textbf{Verse \arabic{section}}}\medskip}

\newenvironment{customtext}%
  {\leftskip=1em \rightskip=1em }%
  {\ifhmode \par \fi}
\newcommand\mstyle[1]{\begin{customtext}\setlength{\parindent}{0pt}{\large
    \textbf{#1}} \\
    {\sffamily #1}\end{customtext}\medskip}

\begin{document}

\mverse
\mstyle{This is a custom verse}
\lipsum

\end{document}

我看了两者LaTeX 条件表达式以及如何根据 documentclass 选项有条件地执行某些操作？但我的情况有所不同。
