5 使用 listings 宏包排版代码的时候，如何在行号和代码块之间加上一条竖线以区分代码和行号？

看看 listings 文档，用 frame = L 就是双线了。颜色自己查查手册了。示例如下：

\RequirePackage{filecontents}
\begin{filecontents*}{\jobname.c}
(function (__global) {
     var tmp0, tmp1,....;
     tmp13 = function (a) {
         var tmp14;
         tmp14 = a;
         return tmp14;
     };
     ...
     tmp16 = function (flag) {
        ...
        tmp20 = tmp21 == tmp22;
        if (tmp20) {
             tmp26 = 'x';
             tmp24 = __global[tmp26];
             tmp25 = 1;
             tmp23 = tmp24 * tmp25;
             return tmp23;
         }
     ...
     tmp7 = tmp16(tmp10, tmp11);
     ...
}(typeof global === 'undefined' ? this : global));
\end{filecontents*}


\documentclass{scrartcl}

\usepackage{listings}
\usepackage{xcolor}


\lstdefinelanguage{HTML5}{

    tabsize=2,

}


\begin{document} 
\lstinputlisting{\jobname.c}
\clearpage
The following lines lines shows how to~\dots
\lstinputlisting[firstline=1,lastline=7]{\jobname.c}
The following lines shows that \dots
\lstinputlisting[firstline=9,firstnumber=10]{\jobname.c}
\end{document} 

效果：
