我正在尝试将 perl 脚本包含在 pod 中。似乎 listings-package 未将 pod-documentation 部分检测为注释，这会破坏列表的其余部分。如何修复此行为？
最小不工作示例（它编译并显示失败）：
\documentclass[a4paper, 10pt, oneside]{scrreprt}
\usepackage[utf8]{inputenc} % Zeichenkodierung
\usepackage[T1]{fontenc} % Schriftart
\usepackage{xcolor,listings} %bindet das Paket Listings ein
\definecolor{comment}{rgb}{.15,.4,.15} % hellgruen
\definecolor{keywd1}{rgb}{.15,.15,.6} % dunkelblau
\definecolor{keywd2}{rgb}{.35,.5,.55} % hellblau
\definecolor{string}{rgb}{.5,.15,.15} % dunkelrot
\definecolor{gray}{rgb}{0.4,0.4,0.4}
\definecolor{darkblue}{rgb}{0.0,0.0,0.6}
\definecolor{cyan}{rgb}{0.0,0.6,0.6}
\lstset{language=perl,
basicstyle={\small} ,
keywordstyle=\color{blue!80!black!100},
identifierstyle=,
morecomment=[s]{=pod}{=cut}, % <------------- This doesn't help!
commentstyle=\color{green!50!black!100},
stringstyle=\ttfamily,
breaklines=true,
numbers=left,
numberstyle=\tiny,
frame=single,
backgroundcolor=\color{blue!3},
caption={Java-Code},
captionpos=t,
literate= %
{Ä}{{\"A}}1
{Ö}{{\"O}}1
{Ü}{{\"U}}1
{ß}{{\ss}}1
{ä}{{\"a}}1
{ö}{{\"o}}1
{ü}{{\"u}}1
{~}{{\textasciitilde}}1
}
\begin{document}
\begin{lstlisting}[language=perl,caption={Test-Skript für Geschwindigkeit},label=script:speed]
#!/usr/bin/env perl
=pod
=head3 command-line switches
-r, --remote <string> The remote Host to test. This is required!
-i, --iterations <number> Iterations for testing.
-v, --verbose Print, what's currently happening.
=head3 main
Main procedure. Needed parameters: remote-host as string, iterations as number,
verbosity as empty or non-empty. Returns 0 if everything went ok, else other
numbers.
=cut
my $bla;
doSomething(@INC, $bla);
\end{lstlisting}
\end{document}
结果：
答案1
morecomment=[s]{=pod}{=cut}
是正确的做法。在这种情况下，存在编码问题，所以这=不是一个等号，而是一个类似的东西。
