我正在使用 newfile.sty 生成一个文件，然后再次读取它。使用 Koma-Script 时，它自 TeXLive 2020 起停止工作：如果文件在 \chapter 或 \section 等分段命令后包含换行符，则 \readstream 会在换行符后停止读取流：
最小示例：
\documentclass{scrartcl}
\usepackage{newfile}
\begin{document}
\section{Eins}
Writing into a file here:
\newoutputstream{lsg}
\openoutputfile{min.lsg}{lsg}
\addtostream{lsg}{This is before the section \protect\section{Zwei} and this is after it.}
\addtostream{lsg}{This is after a newline in the file.}
\closeoutputstream{lsg}
Reading from file stops at the first newline character that appears after the
sectioning command:
\newinputstream{lsg}%
\openinputfile{min.lsg}{lsg}%
\readstream{lsg}
\end{document}
使用标准 article.cls 它可以按预期工作：
\documentclass{article}
\usepackage{newfile}
\begin{document}
\section{Eins}
Writing into a file here:
\newoutputstream{lsg}
\openoutputfile{min.lsg}{lsg}
\addtostream{lsg}{This is before the section \protect\section{Zwei} and this is after it.}
\addtostream{lsg}{This is after a newline in the file.}
\closeoutputstream{lsg}
Reading from file stops at the first newline character that appears after the
sectioning command:
\newinputstream{lsg}%
\openinputfile{min.lsg}{lsg}%
\readstream{lsg}
\end{document}
