![使用描述环境标题](https://linux22.com/image/422212/%E4%BD%BF%E7%94%A8%E6%8F%8F%E8%BF%B0%E7%8E%AF%E5%A2%83%E6%A0%87%E9%A2%98.png)
这与将描述环境与 cleveref 结合使用。我想知道是否有一个干净的解决方案来重复使用描述中的项目标题。例如,给出以下乳胶片:
\begin{description}
\item[TEST\label{itm:test}] test
\end{description}
我需要一些宏,descriptionTitle
例如\descriptionTitle{itm:test}
产生TEST
。我不介意TEST
成为此描述项的引用,但我不想每次有人想出比 TEST 更好的名称时就替换 TEST 和其他名称。
多谢!

您可以使用hyperref
并定义一个名为的标记\namedlabel
:
\documentclass{article}
\usepackage{float}
% definition of environment
\floatstyle{plain}
\newfloat{statement}{tbhp}{los}[section]
\floatname{statement}{Statement}
\usepackage{hyperref}
% definition of named label
\makeatletter
\def\namedlabel#1#2{\begingroup
#2%
\def\@currentlabel{#2}%
\phantomsection\label{#1}\endgroup
}
\makeatother
\begin{document}
\section{Statements with float}
\begin{statement}[ht!]
\begin{description}
\item[\namedlabel{state1}{Statement 1}] This is the first statement.
\item[\namedlabel{state2}{Statement 2}] This is the second statement.
\item[\namedlabel{state3}{Statement 3}] This is the third statement
\end{description}
\caption{Statements}
\label{state:example}
\end{statement}
Reference to whole thing: See Statements \ref{state:example}.
Reference to a single statement: See \ref{state2}.
Note that if you refer to the float you get only the number, but if you refer to the description item itself you get the whole label.
\section{Statements without float}
\begin{description}
\item[\namedlabel{state4}{Statement 4}] This is the fourth statement.
\item[\namedlabel{state5}{Statement 5}] This is the fifth statement.
\end{description}
See \ref{state4}.
\end{document}
我将我创建的浮动环境与此(带有float
包)放在一起,但正如您在第二部分看到的那样,即使没有它,它也能正常工作。
