前提：我必须使用 ShareLaTeX（或 Overleaf），因为我无法在我使用的计算机上安装任何东西。
我正在编写一个包含大量 SAS 代码片段的文档，我正在使用minted并且对结果非常满意，但我想在预定义的关键字中添加更多关键字。
我看到了这篇文章：如何添加自定义 C++ 关键字以供 Minted 识别？但这个解决方案对我来说太难了，我甚至不知道是否可以在 ShareLaTeX 中做这样的事情。
我尝试了一种解决方法，但它并不方便，因为我必须更正代码，而不是简单地从 SAS 编辑器中剪切和粘贴它。
因此，我决定尝试一下listings。我快完成了，但我还没有找到自己喜欢的\color{green}\ttfamily评论风格。

\noindent Pure \texttt{minted}:
\begin{sasminted}

data pippo; |\emph{within escape chars}|
set pluto (firstobs=10 obs=14);
keep paperino;
minnie='a string';
* another comment;
run;
\end{sasminted}
This is what I would like to have (without my workaround):
\begin{sasminted}
/* comment */
data pippo; |\emph{within escape chars}|
set pluto (|\saskeyword{firstobs}|=10 |\saskeyword{obs}|=14);
keep paperino;
minnie='a string';
* another comment;
run;
\end{sasminted}
\noindent with \texttt{listing}:
\begin{lstlisting}
/* comment */
data pippo; |\emph{within escape chars}|
set pluto (firstobs=10 obs=14);
keep paperino;
minnie='a string';
* another comment;
run;
\end{lstlisting}
\noindent\texttt{minted} also recognizes when the \texttt{*} has to be put in black or in green:
\begin{sasminted}
/* this with minted */
proc freq data = pippo;
tables pluto * paperino;
run;
* another comment;
\end{sasminted}
\noindent I prefer minted highlighting also here:
\begin{lstlisting}
/* this with listings */
proc freq data = pippo;
tables pluto * paperino;
run;
* another comment;
\end{lstlisting}
\end{document}
答案1
正如评论中所讨论的，问题在于otherkeywordsSAS 语言定义的定义，它将*和都定义/为关键字。这覆盖了它们作为注释标记的用途。
由于没有宏，解决此问题的最简单方法是删除这两个字符，然后deleteotherkeywords覆盖 列表。但由于也用作 SAS 中的乘法运算符，因此单独执行此操作会导致其中带有 的行从 开始显示为注释，因为您已将其定义为分隔注释。otherkeywords****...;
解决这个问题的方法是删除注释的定义，而*只在注释出现在第 1 列时使用[f]注释定义的类型将其定义为注释。
这是一个完整的例子：

With \texttt{listings}:

\begin{lstlisting}

data pippo; |\emph{within escape chars}|
set pluto (firstobs=10 obs=14);

pippo = pippo*pippo;
