+zhlineskip
+==========
+
+`zhlineskip` is a package for typesetting CJK documents. This package allows users
+to specify two ratios: One between the leading and the font size of the body text
+and the other between those of the footnote text.
+For Latin typography, these ratios usually range
+[from 1.2 to 1.45](https://practicaltypography.com/line-spacing.html),
+but they should be larger for CJK typography (usually from 1.5 to 1.67).
+
+Although CJK text requires larger line spacing, maths formulae should follow
+the rules of Latin typography, since maths often consists of only Latin-based
+letters and symbols. The `zhlineskip` package is capable of restoring the
+maths leading to that of the Latin text.
+
+Finally, it is possible to achieve the “Microsoft Word multiple line spacing”
+style using `zhlineskip`.

+\section{简介}
+
+\pkg{zhlineskip} 宏包允许用户指定正文行距相比于正文字号的倍数(通常建议设置在
+$1.5$ 至 $1.67$ 之间),以及脚注行距相比于脚注字号的倍数。另一方面,由于数学公式
+主要是由西文字符构成的,\pkg{zhlineskip} 还能将数学公式的行距“恢复”成西文
+较为紧凑的行距(通常为西文字号的 $1.2$\nobreak\CJKecglue 倍),使得全文的视觉
+密度较为均匀。最后,本宏包还支持按照 Microsoft Word 进行“多倍行距”排版。
+
+\subsection{宏包依赖}
+
+本宏包是针对中日韩文的横排文档设计出来的,它依赖于下面这些宏包:
+\begin{itemize}
+\item \packagedependency{kvoptions}
+为用户提供载入本宏包的键值选项。
+\item \packagedependency{xintexpr~}
+实现精确的浮点运算,属于\CJKecglue\pkg{xint} 宏集的一个部分。
+\item \packagedependency{etoolbox~}
+处理脚注行距与数学行距时需要打补丁。
+\item \packagedependency{mathtools}

+
+\subsection{中西有别}
+
+在西文排版里,相邻两行\emph{基线}(baseline)之间的距离称为\emph{行距}(leading,
+发音为 led-ding)。这个词的词根是 lead,即\emph{铅}。早在铅字时代,每当工匠填满
+一行铅字之后要开始填下一行,都会在两行之间插入铅条,从而适当地扩大行距。因为西文的
+每个字母四周与其\emph{字框}(em-box,见图\nobreak\CJKecglue\ref{fig:eng-font-size})之间有
+较大的空隙,所以不需要插入很高的铅条。一般来说,西文的行距为\emph{字号}(font
+size)的 $1.2$ 至 $1.45$\nobreak\CJKecglue 倍\footnote{参见
+\url{https://practicaltypography.com/line-spacing.html}。}。
+
+\begin{figure}[h]
+\centering
+\includegraphics{Latinmetrics}
+\caption[西文字体]{西文字体。绿色方框即为 em-box,它在纸上的实际边长就是西文字号。}
+\label{fig:eng-font-size}
+\end{figure}
+
+中文排版虽然没有基线的概念,但有非常相似的概念:\emph{底线}(ideographic baseline,
+见图\nobreak\CJKecglue\ref{fig:chi-font-size})。中文里相邻两行底线之间的距离,与西文里行距的
+概念是一致的。另一概念是上一行底线和下一行\emph{顶线}之间的距离,即\emph{行间距}(line
+gap),这与西文里插入铅条的高度是一致的。由于汉字四周与其字框间的空隙较小,所以需要
+使用比西文更大的行间距。根据场合不同,行间距从字号的 $1/4$ 至 $1$\nobreak\CJKecglue 倍不等:以中文
+书刊为例,行间距一般为字号的 $1/2$ 至 $2/3$\nobreak\CJKecglue 倍\footnote{参见张胜涛、王忆波著
+《方正飞腾4.0实用培训教程》,第\nobreak\CJKecglue6.1.1\nobreak\CJKecglue 节。},即行距约为字号的
+$1.5$ 至 $1.67$\nobreak\CJKecglue 倍。
+
+\begin{figure}[h]
+\centering
+\includegraphics{CJKmetrics}
+\caption[中文字体]{中文字体。汉字字面几乎占满整个字框,字框的边长即为中文字号。}
+\label{fig:chi-font-size}
+\end{figure}
+
+在一般情况下,\CTeX\ 会默认用\CJKecglue\opt{linespread=1.3} 这个文档类
+选项将中文的行距设置为字号的 $1.56$\nobreak\CJKecglue 倍(基础行距是字号的
+$1.2$\nobreak\CJKecglue 倍,而 $1.2 \times 1.3
+= 1.56$)。通过这种方法扩大全文的行距,自然会影响到文章里数学公式的行距。而数学
+公式主要是由西文字符构成的,把它们按照中文的行距进行排版,就会显得有些松散。
+图\nobreak\CJKecglue\ref{fig:math-leading}\CJKecglue 左边是 \CTeX\ 默认
+排版效果,文本、数学看似一紧、一松;右边是配合用\CJKecglue\pkg{zhlineskip} 的效果,
+视觉密度比较均匀。\pkg{zhlineskip} 宏包还允许用户调整数学行距的大小。

+
+综上所述,在进行中西文混排时,最好能够区分中文与西文的行距。在使用\CJKecglue\pkg{zhlineskip}
+时,就可以分开处理中文文本与数学公式的行距。用户甚至还能分别指定正文行距与脚注
+行距,实现灵活的排版。同时,\pkg{zhlineskip} 宏包能恢复各种“多行”数学环境
+(包括矩阵、分类、多行公式推导等等)的行距,使数学公式的行距符合西文行距的规范。
+
+最后,\pkg{zhlineskip} 宏包还支持用户在一定范围内按 Microsoft Word 的
+“多倍行距”进行排版\footnote{本宏包默认假定“被要求”用的字体是中易系列字体,
+这包括 Microsoft Word 里的“宋体”、“黑体”、“楷体”与“仿宋”。若改用其他字体,
+可能需要调整\CJKecglue\opt{MSWordSinglespaceRatio} 的值。
+参见第\nobreak\CJKecglue\ref{sec:key-value}\nobreak\CJKecglue 节
+与第\nobreak\CJKecglue\ref{sec:MS-Word}\nobreak\CJKecglue 节。}。
+用户可以指定“多倍行距”的“倍数”,但是这只保证用 \TeX\ 排出来的文本行距与用
+Microsoft Word 排的行距相同。硬要用 \TeX\ 模仿 Microsoft Word 是没有
+太大意义的。
+
+\section{功能介绍}
+
+首先,请避免使用“多倍行距”这个概念:Microsoft Word 中“单倍行距”的值严重依赖于
+字体(参见第\nobreak\CJKecglue\ref{sec:MS-Word}\nobreak\CJKecglue 节)。
+在严格排版的时候,一般都会给定具体的字号
+与行距,例如字号 $12$\nobreak\CJKecglue 磅、行距 $22$\nobreak\CJKecglue 磅。
+对于一般的用户,指定目标行距相比字号的倍\nobreak 数
+即可——\pkg{zhlineskip} 宏包可以自动提取基础行距(即 \TeX\ 中的单倍行距)
+相比字号的倍数(详见表\nobreak\CJKecglue\ref{tab:default-leading-ratio}),再通过用户指定的
+倍数来计算所需的行伸展因子。因此,不论是中日韩文还是西文的横排文档,都是可以使用
+本宏包的。本宏包的缺省设置更适合中日韩文文档。

+\subsection{载入宏包时的键值选项}
+\label{sec:key-value}
+
+载入\CJKecglue\pkg{zhlineskip} 宏包时可以设定六个基本的键值选项,它们分别是:
+\begin{description}
+\keyvalueitem{bodytextleadingratio}{real}
+指定正文目标行距相比于正文字号的倍数。以书刊为例,建议设置在\nobreak\CJKecglue$1.5$
+至\nobreak\CJKecglue$1.67$ 之间。缺省值是\nobreak\CJKecglue\opt{1.5},
+即 $1/2$\nobreak\CJKecglue 的行间距。
+\keyvalueitem{footnoteleadingratio}{real}
+指定脚注目标行距相比于脚注字号的倍数,它可以比正文的倍数稍小一些,建议设置在正文
+倍数的 $98\%$ 至 $100\%$ 之间。缺省值是\nobreak\CJKecglue\opt{1.48},
+即为正文倍数的\nobreak\CJKecglue$98.67\%$ 左右。
+\keyvalueitem{restoremathleading}{bool}
+指定是否要将数学公式的行距恢复成西文基础行距。缺省值是\nobreak\CJKecglue\opt{true},
+即恢复数学行距。该选项为真时,会自动载入\CJKecglue\pkg{mathtools} 宏包,
+此时还能利用\CJKecglue\cmd{\SetMathEnvironmentSinglespace}\marg{real}
+命令\emph{微调}数学公式的基础行距。
+\keyvalueitem{UseMSWordMultipleLineSpacing}{bool}
+在排版论文时,如果被要求按照 Microsoft Word 来设置“多倍行距”,那么用户可以
+将该选项设置为\nobreak\CJKecglue\opt{true},并通过
+设置\CJKecglue\opt{MSWordLineSpacingMultiple}
+指定“倍数”,这会忽略用户之前指定的正文行距与脚注行距倍数,但是与数学行距的设置
+独立。该选项的缺省值是\nobreak\CJKecglue\opt{false}。
+\keyvalueitem{MSWordLineSpacingMultiple}{real}
+设置 Microsoft Word“多倍行距”的“倍数”,
+仅在\CJKecglue\opt{UseMSWordMultipleLineSpacing} 为真时生效。
+缺省值是\nobreak\CJKecglue\opt{1.15},
+在不修改\CJKecglue\opt{MSWordSinglespaceRatio} 时,
+相当于设置了目标行距为字号的 $1.49140625$\nobreak\CJKecglue 倍,适用于中易字体
+(参见第\nobreak\CJKecglue\ref{sec:MS-Word}\nobreak\CJKecglue 节)。
+\keyvalueitem{MSWordSinglespaceRatio}{real}
+设置 Microsoft Word 的“单倍行距”相比字号的倍数,
+仅在\CJKecglue\opt{UseMSWordMultipleLineSpacing} 为真时生效。
+缺省值是\nobreak\CJKecglue\opt{1.296875},适用于中易字体
+(参见第\nobreak\CJKecglue\ref{sec:MS-Word}\nobreak\CJKecglue 节)。
+若改用其他字体,则需调整该选项的值。
+\end{description}
+
+\subsection{载入宏包后的用户命令}
+
+\subsubsection{调整数学公式的行距}
+
+当键值选项\CJKecglue\opt{restoremathleading}
+为\nobreak\CJKecglue\opt{true} 时,数学公式的行距被
+恢复成字号的 $1.2$\nobreak\CJKecglue 倍。对于某些字面较大的数学字体
+(例如类似 Palatino 的字体),
+这个基础行距会显得过小。此时,用户可以通过如下命令微调数学行距:
+\begin{description}
+\usercmditem{\SetMathEnvironmentSinglespace}{real}
+如果数学字体来自\CJKecglue\pkg{newpxmath} 或是 TeX Gyre Pagella Math,
+那么数学行距在字号 $1.2$\nobreak\CJKecglue 倍的基础上再扩大
+$1.05$\nobreak\CJKecglue 倍更加合适。此时,只需指定
+\verb|\SetMathEnvironmentSinglespace{1.05}|\CJKecglue 即可。
+\end{description}
+本宏包恢复的多行数学环境包括:

+\end{description}
+超出上述列表范围、用户自定义的\emph{数学}环境,可用如下命令恢复其行距:
+\begin{description}
+\usercmditem[6]{\RestoreMathEnvironmentLeading}{env name}
+例如本宏包恢复 \LaTeX\ 数学环境\CJKecglue\env{array} 的行距,是通过
+\verb|\RestoreMathEnvironmentLeading{array}|\CJKecglue 实现的。
+\meta{env name}\CJKecglue 可以是由若干环境名构成的逗号列表。
+\end{description}
+
+\emph{注意,在\CJKecglue\opt{restoremathleading}
+为\nobreak\CJKecglue\opt{false} 时,
+\cmd{\SetMathEnvironmentSinglespace}
+与\CJKecglue\cmd{\RestoreMathEnvironmentLeading} 无效。}
+
+\subsubsection{调整西文文本的行距}
+
+与数学行距命令对应,本宏包还提供两个调整\emph{西文文本}行距的命令,用法类似。
+\begin{description}
+\usercmditem{\SetTextEnvironmentSinglespace}{real}
+如果西文字体来自\CJKecglue\pkg{newpxtext} 或是 TeX Gyre Pagella,
+那么可以指定
+\verb|\SetTextEnvironmentSinglespace{1.05}|。
+\usercmditem[6]{\RestoreTextEnvironmentLeading}{env name}
+使用范例:假设文中的表格仅含西文、数字,此时如果想要文本环境\CJKecglue\env{tabular} 的
+行距与西文行距一致,可通过
+\verb|\RestoreTextEnvironmentLeading{tabular}|\CJKecglue 实现。
+亦可参见例\nobreak\CJKecglue\ref{example:english-block}。
+\meta{env name}\CJKecglue 可以是由若干环境名构成的逗号列表。
+\end{description}
+
+如果作者没有顾及到某些\emph{基本环境}(数学或文本),鼓励用户向\CJKecglue\pkg{zhlineskip} 的
+\href{https://github.com/CTeX-org/ctex-kit/issues}{GitHub 维护页}\CJKecglue
+提供相关信息。
+
+\subsection{使用范例}
+
+下面以 \CTeX\ 提供的\CJKecglue\cls{ctexart} 文档类为例,
+展示\CJKecglue\pkg{zhlineskip} 的使用方法。
+
+\subsubsection*{\example 直接载入}
+
+\begin{verbatim}
+ \documentclass{ctexart}
+ \usepackage{zhlineskip}
+ \begin{document}
+ 正文测试。
+ \end{document}
+\end{verbatim}
+
+\subsubsection*{\example 设置正文行距为字号的 1.6\nobreak\CJKecglue 倍}
+
+\begin{verbatim}
+ % 导言区
+ \usepackage[
+ bodytextleadingratio=1.6, % 设置正文行距倍数为 1.6
+ footnoteleadingratio=1.57 % 设置脚注行距倍数为 1.57
+ ]{zhlineskip} % 缺省数学行距倍数为 1.2
+\end{verbatim}
+
+\subsubsection*{\example 按照 Microsoft Word 设置“1.62\nobreak\CJKecglue 倍行距”}
+
+\begin{verbatim}
+ % 导言区
+ \usepackage[
+ restoremathleading=false, % 可选
+ UseMSWordMultipleLineSpacing, % 需设置为真
+ MSWordLineSpacingMultiple=1.62
+ ]{zhlineskip}
+\end{verbatim}
+
+\subsubsection*{\example\label{example:english-block}中文正文里需要插入成段的西文}
+
+如果需要插入成段的西文,最好的方法是先定义一个西文专用的环境。比如说可以在导言区
+定义如下这个环境:
+\begin{verbatim}
+ \newenvironment{english} % 新建“英文”段落环境
+ {\addvspace\medskipamount} % 段前间距,上文段落需结束
+ {\par\addvspace\medskipamount} % 段后间距
+\end{verbatim}
+注意要先用空行结束上文段落。这时,可以通过\CJKecglue\pkg{zhlineskip} 声明
+\begin{verbatim}
+ \RestoreTextEnvironmentLeading{english} % 恢复“英文”使用紧凑行距
+\end{verbatim}
+将“英文”段落的行距恢复成西文较为紧凑的行距。
+这样一来,正文(也许是中英交替的译文)就会有比较均匀的视觉密度,
+而不至于“中文很挤、英文很散”。

+\subsection{Microsoft Word 中的“单倍行距”}

+
+Microsoft Word 中“单倍行距”的设置,其行距值相比字号的倍数严重依赖于字体,
+甚至还可能因为操作系统的不同而迥然不同。
+表\nobreak\CJKecglue\ref{tab:word-line-height}\CJKecglue 列出
+几种常见字体对应的单倍行距倍数。正是因为“单倍行距”本身随字体、操作系统而变化,
+所以请尽量避免使用“多倍行距”的概念!
