如何给诗节添加编号

Question

我想为我的诗节编号，而不仅仅是诗句。我在包中找不到任何选项verse。有什么解决方法吗？

请考虑以下 MWE

\documentclass{article}
\usepackage{verse}

\begin{document}
\verselinenumbersleft
\setlength{\vrightskip}{-3em}
\poemtitle{Garden}
\poemlines{2}
\begin{verse}
I used to love my garden \\
But now my love is dead \\
For I found a bachelor's button \\
In black-eyed Susan's bed.\\!

I used to love my garden \\
But now my love is dead \\
For I found a bachelor's button \\
In black-eyed Susan's bed.\\!
\end{verse}

\end{document}

\trlap的宏会stackengine帮您完成此操作。通过将其放置在带有索引计数器的宏中，即可实现结果。当您希望重新开始时，\nextverse您必须定期重置计数器。\setcounter{verseno}{0}

经过编辑，以运用我的吟游技巧来继续创作这首充满象征意义的诗。

\documentclass{article}
\usepackage{verse}
\usepackage{stackengine}
\newcounter{verseno}
\def\nextverse{\stepcounter{verseno}\trlap{\Roman{verseno}}}
\begin{document}
\verselinenumbersleft
\setlength{\vrightskip}{-3em}
\poemtitle{Garden}
\poemlines{2}
\begin{verse}
\nextverse 
I used to love my garden \\
But now my love is dead \\
For I found a bachelor's button \\
In black-eyed Susan's bed.\\!

\nextverse
How could this mishap happen? \\
My tool I yet can wield. \\
But that bachelor found his way there; \\
I had failed to plow the field.\\!
\end{verse}

\end{document}

当然，你可以定制效果，例如，

\def\nextverse{\stepcounter{verseno}\trlap{%
  \ifnum\theverseno>1\rule{0pt}{4ex}\fi\bfseries\Roman{verseno}}}

给数字加粗，\nextverse除了第一个数字外，每个数字都有一个额外的空格：

Answer 2

我不会设置新行，因为罗马数字不是这首诗的一部分。在我看来，计数会让人困惑。

我建议使用该verse包中介绍的方法，如下所示：

% arara: pdflatex

\documentclass{article}
\usepackage{verse}

\begin{document}
\verselinenumbersleft
\setlength{\vrightskip}{-3em}
\poemtitle{Garden}
\poemlines{2}
\begin{verse}
\flagverse{I}I used to love my garden \\
But now my love is dead \\
For I found a bachelor's button \\
In black-eyed Susan's bed.\\!

\flagverse{II}I used to love my garden \\
But now my love is dead \\
For I found a bachelor's button \\
In black-eyed Susan's bed.\\!
\end{verse}
\end{document}
