嵌套引号的段落跳跃越来越小

Question

我正在使用 Memoir 和\abnormalparskip{<length>}。

每当我开始写新文章时\begin{quote}，段落之间的间距就会越来越小，直到基本上消失。

这是一个最小的测试用例：

\documentclass{memoir}

\setlength{\parindent}{0em}
\abnormalparskip{1em}

\begin{document}

This is a a normal paragraph. It will space correctly from the next.

This is the second paragraph to show how it is spaced correctly.

\begin{quote}

  This is the first paragraph in a quote. It is not spaced right.

  This paragraph is spaced smaller than the one before it.

  \begin{quote}

    This is yet another paragraph.

    Now you can see the spacing is gone.

  \end{quote}

\end{quote}

\end{document}

结果是：

如何才能使段落跳过始终保持相同的大小？

作为乌尔丽克·菲舍尔提及她的评论\parskip，一种选择是在 内部使用的列表内进行更改quote；为了保持一致性，引用环境也需要进行相同的修改。以下示例代码显示了必要的重新定义：

\documentclass{memoir}

\setlength{\parindent}{0em}
\newlength\myparskip
\setlength\myparskip{1em}
\abnormalparskip{\myparskip}

\makeatletter
\renewenvironment{quote}%
  {\list{}{\rightmargin\leftmargin}%
  \parskip=\myparskip\item[]}%
  {\endlist}
\renewenvironment{quotation}%
  {\list{}{\listparindent 1.5em%
    \itemindent    \listparindent
    \rightmargin   \leftmargin
    \parsep        \z@ \@plus\p@}%
    \parskip=\myparskip\item[]}%
  {\endlist}
\makeatother


\begin{document}

This is a a normal paragraph. It will space correctly from the next.

This is the second paragraph to show how it is spaced correctly.

\begin{quote}

  This is the first paragraph in a quote. It will space correctly from the next.

  This is the second paragraph to show how it is spaced correctly.

  \begin{quote}

    This is another paragraph in a quote. It will space correctly from the next.

    This is the second paragraph to show how it is spaced correctly.

    \begin{quote}

      This is yet another paragraph in a quote. It will space correctly from the next.

      This is the second paragraph to show how it is spaced correctly.

    \end{quote}
  \end{quote}
\end{quote}

\end{document}

从 的名称可以看出\abnormalparskip，该类的作者memoir不喜欢包含非零 的文档\parskip。我完全同意他的观点。

如果您希望您的文档尽可能丑陋（甚至可能更丑陋），您可以这样做。

\documentclass{memoir}

\setlength{\parindent}{0em}
\abnormalparskip{1em}

\makeatletter
\renewcommand*{\list}[2]{%
  \ifnum \@listdepth >5\relax
    \@toodeep
  \else
    \global\advance\@listdepth\@ne
  \fi
  \rightmargin\z@
  \listparindent\everylistparindent
  \itemindent\z@
  \csname @list\romannumeral\the\@listdepth\endcsname
  \def\@itemlabel{#1}%
  \let\makelabel\@mklab
  \@nmbrlistfalse
  #2\relax
  \@trivlist
  \ifm@mnzpskip
    \parsep=\parskip
  \else
    \parskip\parsep
  \fi
  \parindent\listparindent
  \advance\linewidth -\rightmargin
  \advance\linewidth -\leftmargin
  \advance\@totalleftmargin \leftmargin
  \parshape \@ne \@totalleftmargin \linewidth
  \ignorespaces}
\makeatother


\begin{document}

This is a a normal paragraph. It will space correctly from the next.

This is the second paragraph to show how it is spaced correctly.

\begin{quote}

  This is the first paragraph in a quote. It is not spaced right.

  This paragraph is spaced smaller than the one before it.

  \begin{quote}

    This is yet another paragraph.

    Now you can see the spacing is gone.

  \end{quote}

\end{quote}

\end{document}

无需完全复制并修改其定义\list，就可以更快地进行修补。

\documentclass{memoir}
\usepackage{etoolbox}

\setlength{\parindent}{0em}
\abnormalparskip{1em}

\makeatletter
\patchcmd{\list}
 {\parskip\parsep}
 {\ifm@mnzpskip\parsep\parskip\else\parskip\parsep\fi}
 {}{}
\makeatother


\begin{document}

This is a a normal paragraph. It will space correctly from the next.

This is the second paragraph to show how it is spaced correctly.

\begin{quote}

  This is the first paragraph in a quote. It is not spaced right.

  This paragraph is spaced smaller than the one before it.

  \begin{quote}

    This is yet another paragraph.

    Now you can see the spacing is gone.

  \end{quote}

\end{quote}

\end{document}
