使用缩进在此LaTeX文档中插入代码

问题描述

如何将代码插入LaTeX文档?是否有类似的东西:

How do I insert code into a LaTeX document? Is there something like:

\begin{code}## Heading ##
...
\end{code}

我唯一需要的是缩进和固定宽度的字体.语法高亮显示可能很好，尽管绝对不是必需的.

The only thing that I really need is indentation and a fixed width font. Syntax highlighting could be nice although it is definitely not required.

推荐答案

使用 listings 包.

LaTeX标头的简单配置(在\begin{document}之前):

Simple configuration for LaTeX header (before \begin{document}):

\usepackage{listings}
\usepackage{color}

\definecolor{dkgreen}{rgb}{0,0.6,0}
\definecolor{gray}{rgb}{0.5,0.5,0.5}
\definecolor{mauve}{rgb}{0.58,0,0.82}

\lstset{frame=tb,
  language=Java,
  aboveskip=3mm,
  belowskip=3mm,
  showstringspaces=false,
  columns=flexible,
  basicstyle={\small\ttfamily},
  numbers=none,
  numberstyle=\tiny\color{gray},
  keywordstyle=\color{blue},
  commentstyle=\color{dkgreen},
  stringstyle=\color{mauve},
  breaklines=true,
  breakatwhitespace=true,
  tabsize=3
}

您可以使用\lstset{language=Java}更改文档中间的默认语言.

You can change default language in the middle of document with \lstset{language=Java}.

文档中的用法示例:

\begin{lstlisting}
// Hello.java
import javax.swing.JApplet;
import java.awt.Graphics;

public class Hello extends JApplet {
    public void paintComponent(Graphics g) {
        g.drawString("Hello, world!", 65, 95);
    }
}
\end{lstlisting}

结果如下:
