我正在尝试执行一个获取字符串作为参数的宏。我想将字符串作为文件的逐字内容加载。
我主要关注catchfile包装，但没有成功。
我已经看到了
- 如何将外部存储的链接文本添加到超链接中？
- https://stackoverflow.com/questions/414191/using-verbatim-as-part-of-an-argument-for-a-macro
- 如何创建一个宏，当定义宏时，该宏可以读取文件的内容？
我尝试导入的文件充满了各种可能产生误导的字符，因此应按原样进行解释。以下是一小段摘录（这些内容几乎有 10M）：

我需要对每个字符应用一些变换，到目前为止我尝试过的是
\documentclass{article}
\usepackage{catchfile}
\def\xloop#1{
\ifx\relax#1
\else
\framebox[5ex]{
\vrule height 2.5ex depth 1.5ex width 0pt\relax
#1
}\hskip0pt
\expandafter\xloop
\fi
}
\def\addbox#1{\xloop#1\relax}
\makeatletter
\CatchFileDef{\content}{test.sh}{\let\do\@makeother\dospecials\@noligs\obeyspaces\frenchspacing\relax}
\makeatother
\begin{document}
\addbox\content
\end{document}

假设您的文件只有一行，您可以用expl3它读取它们并应用循环。
