记忆和弦在 leadsheets 包中不起作用

Question

所以我尝试使用该leadsheets软件包，但无法使其正常remember-chords工作。我查看了文档（http://ctan.sharelatex.com/tex-archive/macros/latex/contrib/leadsheets/leadsheets_en.pdfp.24)，却找不到我的错误。

我尝试手动插入和弦（不使用快捷方式^）并且它可以起作用，但是会将和弦插入到文本上方和文本中。

运行此代码时出现的错误是，Extra }, or forgotten \endgroup. \end{song} 它尝试通过在第 19 行插入各种字符来解决问题，但失败了。

下面是我的例子。

\documentclass{article}
\usepackage{leadsheets}
\setleadsheets{align-chords={l}}
\begin{document}

\begin{song}[remember-chords]{title={Piano Man}, music={Billy Joel}}
    \begin{verse}
        It's ^{C}nine O' ^{G}clock on a ^*{F}Satur ^{C}day \\
        The ^{F}regular ^{C}crowd shuffles ^{D7}in ^{G} \\
        There's and ^{C}old man ^{G}sitting ^{F}next to ^{C}me \\
        Making ^{F}love to his ^{G}tonic and ^{C}gin ^{G}
    \end{verse}
    \begin{verse}
        He says, ^"Son, can you ^play me a ^*memo ^ry \\
        I'm ^not really ^sure how it ^goes ^ \\
        But it's ^sad and it's ^sweet and I ^knew it com ^plete \\
        When I ^wore a ^younger man's ^clothes." ^
    \end{verse}
\end{song}

\end{document}

Answer 1

remember-chords如果替换标记是一行中的最后一个标记，则会出现问题^。这是一个已知的限制（至少目前如此）。只需在它后面添加一个空组即可：

\documentclass{article}
\usepackage{leadsheets}
\setleadsheets{align-chords={l}}
\begin{document}

\begin{song}[remember-chords]{title={Piano Man}, music={Billy Joel}}
\begin{verse}
  It's ^{C}nine o'^{G}clock on a ^*{F}Satur ^{C}day \\
  The ^{F}regular ^{C}crowd shuffles ^{D7}in ^{G} \\
  There's and ^{C}old man ^{G}sitting ^{F}next to ^{C}me \\
  Making ^{F}love to his ^{G}tonic and ^{C}gin ^{G}
\end{verse}
\begin{verse}
  He says, ^``Son, can you ^play me a ^*memo ^ry \\
  I'm ^not really ^sure how it ^goes ^ {} \\ % <<<
  But it's ^sad and it's ^sweet and I ^knew it com^plete \\
  When I ^wore a ^younger man's ^clothes.'' ^ {} % <<<
\end{verse}
\end{song}

\end{document}
