防止引用环境中出现分页符

Question

我正在尝试排版一些梵文诗句，并在它们周围设置quoting缩进环境。一行包含半节诗句，前半部分以 结尾|，后半部分以 结尾||，我想避免前半部分和后半部分之间出现分页符，这样诗句就不会分成两页。

以下是我尝试过的一些方法：

\documentclass[a4paper]{memoir}
\usepackage{fontspec}
\usepackage[indentfirst=false]{quoting}
\usepackage{lipsum}
\newenvironment{absolutelynopagebreak}%See http://tex.stackexchange.com/posts/94702/edit
  {\par\nobreak\vfil\penalty0\vfilneg
   \vtop\bgroup}
  {\par\xdef\tpd{\the\prevdepth}\egroup
   \prevdepth=\tpd}
\begin{document}
\lipsum[1-4]
\begin{quoting}
xxxxx\\
aaaaaaaaaaaaaaaaaaaaaaaaaa |\\
bbbbbbbbbbbbbbbbbbbbbbbbbb ||\\
cccccccccccccccccccccccccc |\\
dddddddddddddddddddddddddd ||\\
eeeeeeeeeeeeeeeeeeeeeeeeee |\\
ffffffffffffffffffffffffff ||\\
gggggggggggggggggggggggggg |\\
hhhhhhhhhhhhhhhhhhhhhhhhhh ||\\
jjjjjjjjjjjjjjjjjjjjjjjjjj |\\
kkkkkkkkkkkkkkkkkkkkkkkkkk ||\\
%llllllllllllllllllllllllll |\\\nopagebreak%doesn't seem to be doing anything
%mmmmmmmmmmmmmmmmmmmmmmmmmm ||\\
%\begin{samepage}llllllllllllllllllllllllll |\\
%mmmmmmmmmmmmmmmmmmmmmmmmmm ||\\ \end{samepage}%doesn't seem to be doing anything either
%\begin{minipage}{\textwidth}llllllllllllllllllllllllll |\\
%mmmmmmmmmmmmmmmmmmmmmmmmmm ||\end{minipage} %works here but makes a mess in my real file
%\begin{absolutelynopagebreak}llllllllllllllllllllllllll |\\
%mmmmmmmmmmmmmmmmmmmmmmmmmm ||\\\end{absolutelynopagebreak}%breaks out of quoting's indentation, and introduces a new paragraph
llllllllllllllllllllllllll |\\
mmmmmmmmmmmmmmmmmmmmmmmmmm ||\\
nnnnnnnnnnnnnnnnnnnnnnnnnn |\\
oooooooooooooooooooooooooo ||\\


\end{quoting}
\end{document}

我知道我可以手动做一个\newpage，但如果我为每一节写一个命令/环境，然后可能会做一些其他的事情，如格式化，加强计数器等，它就不能被包括在内，我必须手动处理分页符，我当然会尽量避免。

Answer 1

您可以向 添加新键quoting。指定此键应允许仅在明确段落（空白行）处分页。

\documentclass[a4paper]{memoir}
\usepackage[indentfirst=false]{quoting}
\usepackage{lipsum}

\makeatletter
\define@key{quo}{nopagebreak}[true]{\interlinepenalty=10000 }
\makeatother

\raggedbottom

\begin{document}
\lipsum[1-4]
\begin{quoting}[nopagebreak]
xxxxx\\
aaaaaaaaaaaaaaaaaaaaaaaaaa |\\
bbbbbbbbbbbbbbbbbbbbbbbbbb ||\\
cccccccccccccccccccccccccc |\\
dddddddddddddddddddddddddd ||\\
eeeeeeeeeeeeeeeeeeeeeeeeee |\\
ffffffffffffffffffffffffff ||\\
gggggggggggggggggggggggggg |\\
hhhhhhhhhhhhhhhhhhhhhhhhhh ||\\
jjjjjjjjjjjjjjjjjjjjjjjjjj |\\
kkkkkkkkkkkkkkkkkkkkkkkkkk ||\\
llllllllllllllllllllllllll |\\
mmmmmmmmmmmmmmmmmmmmmmmmmm ||\\
llllllllllllllllllllllllll |\\
mmmmmmmmmmmmmmmmmmmmmmmmmm ||\\
llllllllllllllllllllllllll |\\
mmmmmmmmmmmmmmmmmmmmmmmmmm ||\\
nnnnnnnnnnnnnnnnnnnnnnnnnn |\\
oooooooooooooooooooooooooo ||
\end{quoting}
\end{document}

我添加了\raggedbottom，否则第一页的排版将被完全破坏。

尝试\\*在强制换行后抑制分页符。

Answer 3

一个可行的解决方案是将每节诗句放在它自己的quoting环境中，并向其中添加（方便的全局）选项vskip=0cm，这样就无需在诗句后半部分末尾添加手动换行符。

\documentclass[a4paper]{memoir}
\usepackage{fontspec}
\usepackage[indentfirst=false,vskip=0cm]{quoting}
\usepackage{lipsum}
\begin{document}
\lipsum[1-4]
xxxxx
\begin{quoting}
Simple letters make a very bad example. |\\
Simple letters make a very bad example. ||
\end{quoting}
\begin{quoting}
Simple letters make a very bad example. |\\
Simple letters make a very bad example. ||
\end{quoting}
\begin{quoting}
Simple letters make a very bad example. |\\
Simple letters make a very bad example. ||
\end{quoting}
\begin{quoting}
Simple letters make a very bad example. |\\
Simple letters make a very bad example. ||
\end{quoting}
\begin{quoting}
Simple letters make a very bad example. |\\
Simple letters make a very bad example. ||
\end{quoting}
\begin{quoting}
Simple letters make a very bad example. |\\
Simple letters make a very bad example. ||
\end{quoting}
\begin{quoting}
Simple letters make a very bad example. |\\
Simple letters make a very bad example. ||
\end{quoting}
\end{document}
