包poetry会覆盖\\*，这意味着我不能使用它来防止在节中间出现分页符。有没有其他方法可以创建换行符，同时禁止在同一位置出现分页符？最好是设置，而不是在每一行末尾添加一些内容 - 但不管怎样，都行。
例子：
\documentclass[a4paper]{article}
\usepackage{poetry}
\begin{document}
Some text.
\vspace{15cm} % Force poem down page
\poem
Some poetry\\
A metaphor here,\\
A metaphor there.\\!
Here begins another stanza\\
More words.\\!
The final stanza\\
A final metaphor\\
The end\\-
\end{document}
我想防止在节中间出现分页符（在编译示例的最后一节中）。
答案1
不确定这是否足够，但它可以通过增加页面来避免出现 1 行寡妇\baselineskip。它被调用\\*
“修复”通过重新定义 来实现这一点\poem@endpart，这是通过 调用的\\*。原始文件\poem@endpart保存在\poemendpart
以下 MWE 演示了在第 1 页上使用\\*，但不在第 2 页上使用（第 3 页换行）。
\documentclass[a4paper]{article}
\usepackage{poetry}
\makeatletter
\let\poemendpart\poem@endpart
\def\poem@endpart{\enlargethispage{\baselineskip}\poem@endline}
\makeatother
\begin{document}
Some text.
\vspace{16.2cm} % Force poem down page
\poem
Some poetry\\
A metaphor here,\\
A metaphor there.\\!
Here begins another stanza\\
More words.\\!
The final stanza\\
A final metaphor\\*
The end\\-
\clearpage
Some text.
\vspace{16.2cm} % Force poem down page
\poem
Some poetry\\
A metaphor here,\\
A metaphor there.\\!
Here begins another stanza\\
More words.\\!
The final stanza\\
A final metaphor\\
The end\\-
\end{document}
另一个方向的替代方法是强制提前中断，即\clearpage在 之前立即发出\\，例如
\documentclass[a4paper]{article}
\usepackage{poetry}
\begin{document}
Some text.
\vspace{16.2cm} % Force poem down page
\poem
Some poetry\\
A metaphor here,\\
A metaphor there.\\!
Here begins another stanza\\
More words.\clearpage\\!
The final stanza\\
A final metaphor\\
The end\\-
\clearpage
Some text.
\vspace{16.2cm} % Force poem down page
\poem
Some poetry\\
A metaphor here,\\
A metaphor there.\\!
Here begins another stanza\\
More words.\\!
The final stanza\\
A final metaphor\\
The end\\-
\end{document}
补充
这次尝试尝试修改 的使用，\\以便完全避免分页。因此，正常的诗句永远不会在中途跨越页面边界。似乎适用于此用例。
我编辑\poem@endline为以 开头\nopagebreak，这样就不会在这样的行上发生中断。但是，需要在宏中的 实例之后\nopagebreak添加额外的 实例，以防止在行号之后（但在诗行之前）出现分页符。我不认为我全部都得到了，但足以展示 OP 的 MWE 中的效果。\placelineno\hskip
