如何打破很长的线？

Question

我正在使用lstinputlisting从外部文件读取文本。

\lstinputlisting[breaklines]{text.txt}

该文件包含一行很长的内容：

ssssssssssssssssssssssssssstrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrringgggggggggggggggggggggggg ssssssssssssssssssssssssssstrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrringgggggggggggggggggggggggg ssssssssssssssssssssssssssstrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrringgggggggggggggggggggggggg ssssssssssssssssssssssssssstrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrringgggggggggggggggggggggggg ssssssssssssssssssssssssssstrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrringgggggggggggggggggggggggg ssssssssssssssssssssssssssstrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrringgggggggggggggggggggggggg ssssssssssssssssssssssssssstrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrringgggggggggggggggggggggggg ssssssssssssssssssssssssssstrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrringggggggggggggggggggggggggssssssssssssssssssssssssssstrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrringggggggggggggggggggggggggssssssssssssssssssssssssssstrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrringggggggggggggggggggggggggssssssssssssssssssssssssssstrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrringggggggggggggggggggggggggssssssssssssssssssssssssssstrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrringggggggggggggggggggggggggssssssssssssssssssssssssssstrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrringggggggggggggggggggggggggssssssssssssssssssssssssssstrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrringggggggggggggggggggggggggssssssssssssssssssssssssssstrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrringggggggggggggggggggggggggssssssssssssssssssssssssssstrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrringggggggggggggggggggggggggssssssssssssssssssssssssssstrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrringggggggggggggggggggggggggssssssssssssssssssssssssssstrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrringggggggggggggggggggggggggssssssssssssssssssssssssssstrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrringggggggggggggggggggggggggssssssssssssssssssssssssssstrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrringggggggggggggggggggggggggssssssssssssssssssssssssssstrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrringgggggggggggggggggggggggg

我想将该行分成几行连续的行，但它显示“尺寸太大”的错误。

Answer 1

根据对我的问题的评论，我找到了解决方案：

\documentclass{article}
\usepackage{listings}
\makeatletter
\def\@tempA#1#2\@end
{
    \@tempA@{#1}
    \ifx\relax#2\relax
    \else\@tempA#2\@end
    \fi
}
\def\@tempA@#1
{
    {\noexpand#1}
    {{\char`\noexpand#1\allowbreak}}1
}
\edef\@tempB
{
    \noexpand\lstdefinelanguage{text}
    {
        keepspaces,
        breaklines,
        literate=\@tempA !"\#\$\%\&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\\]^_`abcdefghijklmnopqrstuvwxyz\{|\}~\@end
    }
}
\@tempB
\makeatother
\newlength\basewidth
\settowidth\basewidth{\ttfamily\tiny X}
\lstset
{
    language=text,
    basicstyle=\ttfamily\tiny,
    basewidth=\basewidth,
    breakindent=4\basewidth,
    postbreak=\llap{$\hookrightarrow$}
}
\begin{document}
    \lstinputlisting{text.txt}
\end{document}

该解决方案主要基于这个答案。我不知道上面的代码具体是如何工作的，但它确实有效。

奇怪的是，如果行太大，即行跨越两页或更多页，这种方法仍然不起作用。在这种情况下，仍然会显示错误“尺寸太大”。一种可能的解决方法是减小字体大小和页边距，以便行可以容纳在两页以内，尽管这不是一个完美的解决方案。
