我有这个示例 tex 文件，其中有一行包含一个很长的单词。
\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{listings}
\lstset{
breaklines=true,
escapechar=@
}
\usepackage[a4paper,left=1cm,right=1cm,top=2.5cm,bottom=2.5cm]{geometry}
\usepackage[bookmarks]{hyperref}
\hypersetup{
bookmarksnumbered=true,
bookmarksopen=false,
bookmarksopenlevel=1,
colorlinks=true,
pdfstartview=Fit,
pdfpagemode=UseOutlines,
pdfpagelayout=TwoPageRight
}
\title{My Title}
\listfiles
\begin{document}
\pagenumbering{roman}
\maketitle
\tableofcontents
\pagenumbering{arabic}
\newpage
\section{First Section}
\begin{lstlisting}
This is a long line that should haveBeenBrokenAtAnAppropriatePositionWhichDefinetlyExistsButStillFailedToBreakProperly
haveBeenBrokenAtAnAppropriatePositionWhichDefinetlyExistsButStillFailedToBreakProperly
\end{lstlisting}
\end{document}
尽管我使用的是breaklines我的，lstlisting但有问题的行并没有中断。长单词绝对可以放在一行中，如最终 PDF 文件中所示。
有没有办法来解决这个问题没有允许在一个单词内断词吗？

（应 OP 要求发表评论……）
这似乎是该软件包的一个旧版本中的错误。问题中显示listings的输出表明正在使用的和来自 2002 年，以及似乎不再使用的。该软件包有\listfileslistings.stylstmisc.stylstpatch.stylistings很多版本从那时起，较新的版本就不再有这个错误。
升级listings软件包可以修复该问题。
