使用 listings 包的行号从随机数开始

使用 listings 包的行号从随机数开始

我正在使用listings包裹直接从文件中包含代码。在第一个例子中，我的代码按我想要的方式编号，第一行编号为 1，第 11 行编号为 11，...但是，第二个代码块在第二行编号为 2，第 12 行编号为 12，...然后第一个代码块在第 8 行编号为 8。

对于如何解决这个问题，有任何的建议吗？

这是我的代码：

\documentclass{article}
\usepackage{listings, color, setspace, graphics}
\usepackage{fancyhdr, amsmath, amssymb, setspace, amssymb}
\usepackage{pdfpages}

\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{ %
  language=C++,                % 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=10,                   % 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
  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
  keywordstyle=\color{blue},          % keyword style
  commentstyle=\color{dkgreen},       % comment style
  stringstyle=\color{mauve},         % string literal style
}

\setlength{\textwidth}{6.5in}

答案1

如果您想要更常见的列表格式并对每行编号到第 10 行，则需要包含选项firstnumber=1以便每个列表从 1 开始。如果您还希望对第一行进行编号，那么您需要选项numberfirstline=true。

以下是前后的比较：

笔记：

  • stepnumber仅当设置为 1 以外的其他值时，这才是必要的。
  • 您的代码无需进行此更改即可运行，但我还从language初始设置中删除了设置ltset，并将语言指定为可选参数的一部分\lstinputlisting（而不是使用lstset）。我认为这更清楚地体现了您想要的意图。
