請勿使用 Verse 套件重設行號

Question

我想要行號不是使用環境時重置verse。

考慮這個 MWE：

\documentclass{book}
\usepackage{verse}
\poemlines{5}
\begin{document}

\chapter{}
\begin{verse}
Lorem ipsum dolor sit amet, consectetur adipiscing elit\\
Lorem ipsum dolor sit amet, consectetur adipiscing elit\\
Lorem ipsum dolor sit amet, consectetur adipiscing elit\\
Lorem ipsum dolor sit amet, consectetur adipiscing elit\\!

Lorem ipsum dolor sit amet, consectetur adipiscing elit\\
Lorem ipsum dolor sit amet, consectetur adipiscing elit\\
Lorem ipsum dolor sit amet, consectetur adipiscing elit\\
Lorem ipsum dolor sit amet, consectetur adipiscing elit\\!
\end{verse}

{\let\clearpage\relax \chapter{}}
\begin{verse}
Lorem ipsum dolor sit amet, consectetur adipiscing elit\\
Lorem ipsum dolor sit amet, consectetur adipiscing elit\\
Lorem ipsum dolor sit amet, consectetur adipiscing elit\\
Lorem ipsum dolor sit amet, consectetur adipiscing elit\\!

Lorem ipsum dolor sit amet, consectetur adipiscing elit\\
Lorem ipsum dolor sit amet, consectetur adipiscing elit\\
Lorem ipsum dolor sit amet, consectetur adipiscing elit\\
Lorem ipsum dolor sit amet, consectetur adipiscing elit\\!
\end{verse}

\end{document}

有沒有辦法讓行編號繼續計數，即使您已經開始了新verse環境？

Answer 1

（重新定義的）環境在開始時verse將相關計數器設為0。poemline

刪除設定。還需要在環境結束時減一，因為計數器是在開始時步進的。

當需要時，您將發出\setcounter{poemline}{0}重置編號的命令。

\documentclass{book}
\usepackage{verse}
\usepackage{xpatch}

\xpatchcmd{\verse}
  {\setcounter{poemline}{0}}% find
  {}% replace
  {}{}% auxiliary arguments
\xpretocmd{\endverse}{\addtocounter{poemline}{-1}}{}{}

\poemlines{5}
\begin{document}

\chapter{}
\begin{verse}
Lorem ipsum dolor sit amet, consectetur adipiscing elit\\
Lorem ipsum dolor sit amet, consectetur adipiscing elit\\
Lorem ipsum dolor sit amet, consectetur adipiscing elit\\
Lorem ipsum dolor sit amet, consectetur adipiscing elit\\!

Lorem ipsum dolor sit amet, consectetur adipiscing elit\\
Lorem ipsum dolor sit amet, consectetur adipiscing elit\\
Lorem ipsum dolor sit amet, consectetur adipiscing elit\\
Lorem ipsum dolor sit amet, consectetur adipiscing elit\\!
\end{verse}

{\let\clearpage\relax \chapter{}}
\begin{verse}
Lorem ipsum dolor sit amet, consectetur adipiscing elit\\
Lorem ipsum dolor sit amet, consectetur adipiscing elit\\
Lorem ipsum dolor sit amet, consectetur adipiscing elit\\
Lorem ipsum dolor sit amet, consectetur adipiscing elit\\!

Lorem ipsum dolor sit amet, consectetur adipiscing elit\\
Lorem ipsum dolor sit amet, consectetur adipiscing elit\\
Lorem ipsum dolor sit amet, consectetur adipiscing elit\\
Lorem ipsum dolor sit amet, consectetur adipiscing elit\\!
\end{verse}

\end{document}
