乳胶:数学以外的可拉伸花括号 [英] Latex: stretchable curly braces outside math

问题描述

我正在制作一些乳胶投影仪幻灯片(但我认为这本身不是投影仪特定的问题).

我有以下内容:

\begin{itemize}
\item Issue1
\item Issue2
\item Issue3
\end{itemize}

现在，我要在第1个和第2个问题上展开的项目后面留一个合适的花括号(即'}').当然，我想在花括号后面写点东西.

在一个完美的世界里，我会写一些类似的东西:

\begin{itemize}
\left .
\item Issue1
\item Issue2
\right \} One and Two are cool
\item Issue3
\end{itemize}

这不起作用，因为我不在数学环境中，也无法将整个代码片段放入数学环境中，因为在这种情况下逐项操作不起作用.

是否有一个干净的解决方案或黑客可以产生我想要的结果?

解决方案

我将使用tikz并进行覆盖.

首先包含适当的软件包(您可能不需要包含tikz，因为这是一个比较容易的问题):

\usepackage{tikz}
\usetikzlibrary{decorations.pathreplacing}

然后，当您创建列表时，请在每个项目后面的位置命名:

\begin{itemize}
    \item Issue 1     
        \tikz[remember picture] \node[coordinate,yshift=0.5em] (n1) {}; 
    \item Issue 2
        \tikz[remember picture] \node[coordinate] (n2) {};
    \item Issue 3
\end{itemize}

(注意:我将y值上移了1/2行可能会更好.)

由于我们使用了remember picture，因此可以在叠加层中引用这些位置:

  \begin{tikzpicture}[overlay,remember picture]
      \path (n2) -| node[coordinate] (n3) {} (n1);
      \draw[thick,decorate,decoration={brace,amplitude=3pt}]
            (n1) -- (n3) node[midway, right=4pt] {One and two are cool};
  \end{tikzpicture}

路径用于处理宽度不同的项目.此编辑来自 ESultanik的答案. /p>

结果是:

旁注:您可以删除所有remember picture选项，并添加以下内容以自动为所有图片添加记忆:

\tikzstyle{every picture}+=[remember picture]

I am producing some latex beamer slides (but I think it is not a beamer specific question per se).

I have the following:

\begin{itemize}
\item Issue1
\item Issue2
\item Issue3
\end{itemize}

Now, I want to have a right curly brace (i.e. '}') behind the items spreading over issue1 and issue2. And of course I want to write something behind that curly brace.

In a perfect world I would write something like:

\begin{itemize}
\left .
\item Issue1
\item Issue2
\right \} One and Two are cool
\item Issue3
\end{itemize}

This does not work because I am not in a math environment and I can not put the whole snippet inside a math environment because itemize would not work in that case.

Is there a clean solution or a hack to produce my desired result?

Regards, Bastian.

解决方案

I'd use tikz and make an overlay.

First include the proper packages (you may not need to include tikz since this is a beamer question):

\usepackage{tikz}
\usetikzlibrary{decorations.pathreplacing}

Then when you make your list, give names to the places after each item:

\begin{itemize}
    \item Issue 1     
        \tikz[remember picture] \node[coordinate,yshift=0.5em] (n1) {}; 
    \item Issue 2
        \tikz[remember picture] \node[coordinate] (n2) {};
    \item Issue 3
\end{itemize}

(Note: I shifted the y value up by 1/2 of a line maybe more would be better.)

Because we used remember picture we can refer to these places in an overlay:

  \begin{tikzpicture}[overlay,remember picture]
      \path (n2) -| node[coordinate] (n3) {} (n1);
      \draw[thick,decorate,decoration={brace,amplitude=3pt}]
            (n1) -- (n3) node[midway, right=4pt] {One and two are cool};
  \end{tikzpicture}

The path is there to deal with items that do not have the same width. This edit comes from ESultanik's answer.

The result is:

Side note: You can remove all of the remember picture options and add the following to automatically add remember to all pictures:

\tikzstyle{every picture}+=[remember picture]
