我的自定义字母和部分导致我的一些分页符破坏了我的布局。请参阅通过 XeLaTeX 运行的附加代码的输出示例。
下一页的第 2 节实际上应该写在 117 行字母的底部旁边。否则，从 117 行字母开始的整个章节应该移到下一页。但在\nopagebreak我的章节之前强行插入也会破坏 118 行字母之前的页面，这是错误的，因为第 117 章很短，出于明显的美观原因，不能放在自己的页面上。
我尝试过使用\nopagebreak[n]，但没有得到预期的结果。是否可以针对 TeX 决定分页时更具体自定义优先级？

答案1
请注意，可以将代码片段插入命令\needspace{3\baselineskip}的中间参数\titleformat，如下所示
\titleformat{\section}{\needspace{3\baselineskip}}{\lettrine{\thesection}}{0em}
{}[\vskip-1\baselineskip]
这肯定比在每个命令前面插入指令要好\section。（请注意，\Needspace宏的精确度不如\needspace确定页面上还剩下多少空间。）
在另一个主题上，我注意到你有很多实例\textsc{Lord}；你可能要考虑加载xspace包，定义一个宏，例如
\newcommand{\Lord}{\textsc{Lord}\xspace}
然后在文档正文中将 全局更改为\textsc{Lord}。\Lord我推测这会使代码的可读性大大提高。另外，如果您想更改主的称谓的“样式”（例如，添加颜色），则只需在一个实例中执行此操作，即在文档的序言中。
附录：我忍不住要再快速提出两点与文档格式/外观相关的意见。首先，第 116:6 节的第二行只有一个非常短的单词（“me”）；如果在单词“helped”和“me”之间插入一个连字符（波浪号），则整节经文将只占用一行。（附带的好处是，整篇诗篇 117 篇现在也适合放在页面上。）其次，尽管它们的大小为，但每节经文开头的数字在外观上相当突兀（部分原因是它们采用粗体显示）。您是否考虑过为它们指定而不是 的\small大小？\footnotesize\small
答案2
我发现这个先前的答案对另一个问题似乎有效，当我使用它修改为\Needspace*{3\baselineskip}
