整个逐字部分均采用斜体字体

Question

如何在 verbatim 环境中将字体格式更改为斜体？

\documentclass[a4paper]{article} 
\begin{document}

\begin{Verbatim}
@book{book;
title = {title};
author = {author};
volume = {1};
year = {2015};
publisher = {x}
}
\end{Verbatim}

\end{document}

Answer 1

在当地，

\documentclass{article}
\usepackage{fancyvrb}

\begin{document}

\begin{Verbatim}[fontshape=it]
@book{book,
title = {title},
author = {author},
volume = {1},
year = {2015},
publisher = {x}
}
\end{Verbatim}

\end{document}

从全球来看，

\documentclass{article}
\usepackage{fancyvrb}

\fvset{fontshape=it}

\begin{document}

\begin{Verbatim}
@book{book,
title = {title},
author = {author},
volume = {1},
year = {2015},
publisher = {x}
}
\end{Verbatim}

\end{document}

这将给出斜体等宽字体：

对于标准verbatim环境，重新定义\verbatim@font：

\documentclass{article}

\makeatletter
\renewcommand\verbatim@font{\itshape}
\makeatother

\begin{document}

\begin{verbatim}
@book{book,
title = {title},
author = {author},
volume = {1},
year = {2015},
publisher = {x}
}
\end{verbatim}

\end{document}

另一个选项是verbatimbox允许在可选参数中提供格式化宏的包。它具有环境verbnobox，其功能类似于verbatim，以及verbbox将逐字内容放入已保存框的环境，该框稍后可以使用内联输出，theverbbox此处显示在内\fbox。

\documentclass[a4paper]{article}
\usepackage{verbatimbox} 
\begin{document}

\noindent Normal Size, italic shape verbatim text
\begin{verbnobox}[\itshape]
@book{book;
title = {title};
author = {author};
volume = {1};
year = {2015};
publisher = {x}
}
\end{verbnobox}

\begin{verbbox}[\itshape\tiny]
@book{book;
title = {title};
author = {author};
volume = {1};
year = {2015};
publisher = {x}
}
\end{verbbox}
Here is \fbox{\theverbbox} inline.

\end{document}

宏的可选参数verbatimbox实际上非常可编程。此处，“程序”存储在 中\tmp。

\documentclass[a4paper]{article}
\usepackage{verbatimbox} 
\begin{document}
\def\tmp{\ifnum\theVerbboxLineNo=2\itshape\else%
         \ifnum\theVerbboxLineNo=4\leavevmode\llap{$\bullet$ }\fi\fi}
\begin{verbnobox}[\tmp]
@book{book;
title = {title};
author = {author};
volume = {1};
year = {2015};
publisher = {x}
}
\end{verbnobox}
\end{document}
