如何用逐字记录环境创建新的Beamer环境? [英] How do I create a new Beamer environment with a verbatim environment?

问题描述

我正在创建一个Beamer演示文稿，其中包含很多LaTeX示例，必须在逐字记录环境中使用.我已经厌倦了输入

I'm creating a Beamer presentation that has a lot of example LaTeX in it, which has to go in a verbatim environment. I'm getting tired of typing

\begin{example}
  \begin{verbatim}
  Verbatim Text
  \end{verbatim}
\end{example}

我希望创建一个新的命令或环境，以简化我的工作.我也需要块和定理，因为我也经常使用它们.但是，如果我能举例说明，那么应该很容易将其翻译为另一个示例.

I wish to create a new command or environment that will shorthand this for me. I also need this for blocks and theorems, since I'm using those frequently as well. But if I can figure it out for examples, it should be easy to translate to another example.

我不能仅使用\ begin {verbatim}来创建新的环境或命令，因为它会切断其余的命令.因此，我切换到使用fancyvrb软件包，并尝试了以下操作:

I can't create a new environment or command using just \begin{verbatim}, since it cuts off the rest of the command. So I switched to using the fancyvrb package, and tried the following:

\DefineVerbatimEnvironment
{MyVerbatim}{Verbatim}{}

\newcommand{\makeexample}[1]{
    \begin{example}
        \begin{MyVerbatim}
        #1

        \end{MyVerbatim}
    \end{example}
}

\makeenvironment{VerbExample}{\begin{example}
    \begin{MyVerbatim}}{\end{MyVerbatim}\end{example}}

这给了我\ makeexample {Example Text}命令和\ begin {VerbExample} ... \ end {VerbExample}环境，但是它们在编译时仍然会引发错误.我要在其中使用它们的框架看起来像这样(框架上有[易碎]选项，所以不是那样).

That gives me the \makeexample{Example Text} command, and the \begin{VerbExample}...\end{VerbExample} environment, but they both still throw errors on compile. The frame I'm trying to use them in looks like this (I've got the [fragile] option on the frame, so it's not that).

\begin{frame}[fragile]
    \frametitle{Why Doesn't Verbatim Work?}

    \makeexample{Verbatim Text}

    \begin{VerbExample}
        Verbatim Text
    \end{VerbExample}
\end{frame}

推荐答案

环境定义:

\newenvironment{VerbExample}
{\example\semiverbatim}
{\endsemiverbatim\endexample}

框架定义:

\begin{frame}[fragile]
\frametitle{Title}
\begin{VerbExample}
test test test $t$ $\\omega$
test test
\end{VerbExample}
\end{frame}

逐字记录不能进入\newcommand.半动词由Beamer定义，并且可以很好地工作. 必须将三个字符\ { }转义为\\ \{ \}.

Verbatim cannot go inside \newcommand. Semiverbatim is defined by Beamer and works well with it. The three characters \ { } must be escaped as \\ \{ \}.
