突出显示 .diff 文件

有没有办法突出显示差异文件的语法（即通过使用包listings）？

答案1

您只需使用包即可完成此操作listings，甚至不需要外部预处理器。listings没有差异样式，但您可以像这样定义一个：

\lstdefinelanguage{diff}{
  morecomment=[f][\color{blue}]{@@},     % group identifier
  morecomment=[f][\color{red}]-,         % deleted lines 
  morecomment=[f][\color{green}]+,       % added lines
  morecomment=[f][\color{magenta}]{---}, % Diff header lines (must appear after +,-)
  morecomment=[f][\color{magenta}]{+++},
}

按通常方式使用它。例如，\lstinputlisting[language=diff]{myfile.diff}。

更新：Diff 查看器通常会突出显示线条的背景，而不是为文本着色。这可以借助 Martin Scharrer 的lstlinebgrd软件包添加，该软件包可在 CTAN 上找到，网址为lstaddons捆绑包（或者从软件包主页）

答案2

铸造？

\begin{minted}{diff}
<diff data goes here>
\end{minted}

会起作用，或者

\inputminted{diff}{path/to/file.diff}

如果您只想从文件中读取差异。Minted 还提供了清单您可以使用命令将其包装在浮动框中，就像图形或表格一样。

我扩展了 alexis 的答案以涵盖更多格式：普通格式（diff）、统一格式（diff -u）、上下文格式（diff -c）和来自 Git 的差异（git diff）：

\lstdefinelanguage{diff}{
  sensitive=true,
  % diff command line
  morecomment=[f][\color{gray}][0]{diff},
  % commit identifiers for git diff
  morecomment=[f][\color{gray}][0]{index},

  morecomment=[f][\color{blue}][0]{@@},
  % hunk location/line numbers for context format
  morecomment=[f][\color{magenta}][0]{***},
  % changed line for context format
  morecomment=[f][\color{violet}][0]{!},
  % deleted lines for unified format
  morecomment=[f][\color{red!60!black}][0]-,
  % added lines for unified format
  morecomment=[f][\color{green!60!black}][0]+,
  % file name and time stamp old file
  morecomment=[f][\color{magenta}][0]{---},

  morecomment=[f][\color{magenta}][0]{+++},
  % Binary files ... differ
