在清单中突出显示代码块 [英] Highlighting a Chunk of Code within a lstlisting

问题描述

我在lstlisting环境中有一堆代码.如何在环境中仅突出显示特定的代码块(彩色背景)?

I have a bunch of code in a lstlisting environment. How can I highlight (color background) just a particular chunk of code within the environment?

推荐答案

您可以在列表中使用\ colorbox和转义字符:

You can use \colorbox and an escape character inside your listing:

添加到您的序言

  \usepackage{color}

  \definecolor{light-gray}{gray}{0.80}

然后在文档中像这样使用它:

then use it like this in your document:

  \begin{lstlisting}[escapechar=!]
  def mult(m: Matrix[Int], n: Matrix[Int]) {
    val p = !\colorbox{light-gray}{new MatrixInt}!(m.rows, n.cols)
  }
  \end{lstlisting}
