![使用枚举中的键值到另一个键值](https://linux22.com/image/312096/%E4%BD%BF%E7%94%A8%E6%9E%9A%E4%B8%BE%E4%B8%AD%E7%9A%84%E9%94%AE%E5%80%BC%E5%88%B0%E5%8F%A6%E4%B8%80%E4%B8%AA%E9%94%AE%E5%80%BC.png)
这是Enumitem \SetEnumitemKey 与前后多个键之间发生冲突。
我想在另一个列表的定义中使用列表中的键值。这里我使用了 \Pointilles 的更好定义,它允许第二个参数,即点之间的垂直空间。
因此我用此代码代替旧代码:
\usepackage{xargs}
\newcommand{\auxpts}[1]{\makebox[\linewidth]{\dotfill} #1}
% Pointilles
\newcommandx{\Pointilles}[2][1=1,2=\bigbreak]{%
\vspace*{-\medskipamount}
\multido{\i=1+1}{#1}{%
\auxpts{#2}
}
}
并将每次出现的 替换\Pointilles{#1}
为\Pointilles[#1]
,并将替换\Pointilles{2}
为\Pointilles[2]
。
最终代码如下:
\documentclass[twocolumn]{article}
\usepackage[a4paper, top=0.5cm, bottom=1.6cm, left=0.7cm , right=0.7cm]{geometry}
\parindent0cm
\usepackage{multido}
\usepackage{enumitem}
\usepackage{multicol}
\usepackage{xargs}
\newcommand{\auxpts}[1]{\makebox[\linewidth]{\dotfill} #1}
% Pointilles
\newcommandx{\Pointilles}[2][1=1,2=\bigbreak]{%
\vspace*{-\medskipamount}
\multido{\i=1+1}{#1}{%
\auxpts{#2}
}
}
\newlist{innanswers}{enumerate}{1}
\setlist[innanswers]{
label=\arabic*.,
before=\maybemulticols\maybedots,
after=\maybefinaldots\maybeendmulticols
}
\newenvironment{answers}[1][]
{\setkeys{m45}{#1}\innanswers}
{\endinnanswers}
\let\maybemulticols=\relax
\let\maybeendmulticols=\relax
\let\maybedots=\relax
\let\maybefinaldots=\relax
\def\doitemdots#1{%
\let\olditem\item% save the standard definition of \item in a macro, \olditem
\firstItemtrue% set the toggle for first item in the list to true
\def\item{%
\iffirstItem
\olditem\firstItemfalse
\else
\newline\Pointilles[#1][\bigbreak]\mbox{}\olditem %TODO here need to replace \bigbreak by the value of a parameter
\fi
}% new, temporary defition of \item
}
\def\dofinaldots#1{%
\ \newline \Pointilles[#1][\bigbreak]\mbox{} %TODO here need to replace \bigbreak by the value of a parameter
}
\makeatletter
\define@key{m45}{cols}{%
\def\maybemulticols{\begin{multicols}{#1}}%
\def\maybeendmulticols{\end{multicols}}%
}
\newif\iffirstItem\firstItemfalse
\define@key{m45}{dots}{%
\def\maybedots{\doitemdots{#1}}
\def\maybefinaldots{\dofinaldots{#1}}
}
\makeatother
%==========================================
\begin{document}
\Pointilles[2]
\hrule
\begin{answers}[cols=4]
\item first
\item second
\item third
\item fourth
\end{answers}
\hrule
\begin{answers}[dots=2]
\item first
\item second
\item third
\item fourth
\end{answers}
\hrule
\begin{answers}[cols=2, dots=2]
\item first
\item second
\item third
\item fourth
\end{answers}
\hrule
\begin{answers}[dots=2, cols=2]
\item first
\item second
\item third
\item fourth
\end{answers}
\hrule
\end{document}
所以问题是:我该如何在列表中传递一个新的键值而不是默认值\bigbreak
(两行匹配的值有一个%TODO
)?
