创建变量分页符

Question

是否可以通过测量文本/页面空间来程序化地生成分页符？我遇到了一个问题，您可以在此处看到：

这张图片有两个问题。首先，标题应该溢出到下一页，因为它不适合……但更重要的是，更令人恼火的是，标题应该被强制移到下一页，因为它的内容不适合同一页。

我正在从 javascript 程序生成我的 latex，因此发布代码片段有点困难，但我可以向您展示我正在使用的函数/环境......它是已接受答案中的第二个代码块 这里

对于测量文本有什么想法或技巧吗？

以下是从上面的链接生成我的自定义列表的代码：

\documentclass{article}
\usepackage{fancyhdr} 
\usepackage[head=41.68335pt]{geometry} 
\usepackage{enumitem} 
\usepackage{indentfirst} 
\pagestyle{empty}
%% I use a box for your "title" and save its width in "\mytitlewidth"
\newlength{\mytitlewidth}
\newlength{\mytopsep}
\newsavebox{\mytitlebox}
%% and environment to handle your list
\newenvironment{enumwithinenum}[1]
  {\setlength{\mytitlewidth}{\dimexpr0.30\textwidth\relax}%%'   
   \setlength{\mytopsep}{2ex}%%'
   %% save the title in a box so we can access its height later to
   %% use to adjust where the next enumerate begins.
   \begin{lrbox}{\mytitlebox}%%'
     \begin{minipage}[t]{\dimexpr\mytitlewidth\relax} 
       \raggedright\strut
       \textbf{#1}
       \par\xdef\tpd{\the\prevdepth}%%'
     \end{minipage}%%'
   \end{lrbox}%%"
   \usebox{\mytitlebox}%%'

Answer 1

我会将标题与第一项更紧密地绑定在一起：

\documentclass{article}
\usepackage{fancyhdr} 
\usepackage[head=41.68335pt]{geometry} 
\usepackage{enumitem} 
\usepackage{indentfirst} 
\pagestyle{empty}
%% I use a box for your "title" and save its width in "\mytitlewidth"
\newlength{\mytitlewidth}
\newlength{\mytopsep}
\newsavebox{\mytitlebox}
%% and environment to handle your list
\newenvironment{enumwithinenum}[1]
  {\setlength{\mytitlewidth}{\dimexpr0.30\textwidth\relax}%%'   
   \setlength{\mytopsep}{2ex}%%'
   %% save the title in a box so we can access its height later to
   %% use to adjust where the next enumerate begins.
   \begin{lrbox}{\mytitlebox}%%'
     \begin{minipage}[t]{\dimexpr\mytitlewidth\relax} 
       \raggedright\strut
       \textbf{#1}
       \par\xdef\tpd{\the\prevdepth}%%'
     \end{minipage}%%'
   \end{lrbox}%%"
   \begin{enumerate}[align=left,
                     label={\llap{\smash{\box\mytitlebox}}.\arabic*},
                     leftmargin=\dimexpr\mytitlewidth+2em\relax,
                     topsep=\mytopsep,
                    ]
  }
  {\end{enumerate}}
