Latex插入代码块

步骤

• 最前面加入listings包：

  \usepackage{listings}
  

• 代码段

  \begin{lstlisting}
  % 代码段
  \end{lstlisting}
  

• 代码块的基本设置：

  \lstset{
   columns=fixed,       
   numbers=left,                                        % 在左侧显示行号
   numberstyle=\tiny\color{gray},                       % 设定行号格式
   frame=none,                                          % 不显示背景边框
   backgroundcolor=\color[RGB]{245,245,244},            % 设定背景颜色
   keywordstyle=\color[RGB]{40,40,255},                 % 设定关键字颜色
   numberstyle=\footnotesize\color{darkgray},           
   commentstyle=\it\color[RGB]{0,96,96},                % 设置代码注释的格式
   stringstyle=\rmfamily\slshape\color[RGB]{128,0,0},   % 设置字符串格式
   showstringspaces=false,                              % 不显示字符串中的空格
   language=c++,                                        % 设置语言
  }
  

另外，一个模板：

  \lstset{ %
    language=Octave,                % the language of the code
    basicstyle=\footnotesize,           % the size of the fonts that are used for the code
    numbers=left,                   % where to put the line-numbers
    numberstyle=\tiny\color{gray},  % the style that is used for the line-numbers
    stepnumber=2,                   % the step between two line-numbers. If it's 1, each line 
                                    % will be numbered
    numbersep=5pt,                  % how far the line-numbers are from the code
    backgroundcolor=\color{white},      % choose the background color. You must add \usepackage{color}
    showspaces=false,               % show spaces adding particular underscores
    showstringspaces=false,         % underline spaces within strings
    showtabs=false,                 % show tabs within strings adding particular underscores
    frame=single,                   % adds a frame around the code
    rulecolor=\color{black},        % if not set, the frame-color may be changed on line-breaks within not-black text (e.g. commens (green here))
    tabsize=2,                      % sets default tabsize to 2 spaces
    captionpos=b,                   % sets the caption-position to bottom
    breaklines=true,                % sets automatic line breaking
    breakatwhitespace=false,        % sets if automatic breaks should only happen at whitespace
    title=\lstname,                 % show the filename of files included with \lstinputlisting;
                                    % also try caption instead of title
    keywordstyle=\color{blue},          % keyword style
    commentstyle=\color{dkgreen},       % comment style
    stringstyle=\color{mauve},         % string literal style
    escapeinside={\%*}{*)},            % if you want to add LaTeX within your code
    morekeywords={*,...}               % if you want to add more keywords to the set

}
