建议不要用「让代码就像文字一样，从当前页继续，但如果当前页空间不足时自动换页」这种表述，而是用「breakable listings」
太困了，只给例子，个人觉得tcb是比较好的实践了...
你要综合看tcolorbox和listings的文档
几个关键的option为:
listing remove caption=falsecaption={Rust is Genshin Impact of coding}captionpos=t(这是默认值，可调)label={mycode}
\documentclass{article}
\usepackage[margin=1in]{geometry}
\usepackage{lipsum}
\usepackage[most]{tcolorbox}
\usepackage{hyperref}
\tcbuselibrary{listings}
\newtcbinputlisting{\mylisting}[2][]{%
enhanced jigsaw,sharp corners,title={example~code},empty,left=1cm,breakable,%
listing file={#2},listing only,listing remove caption=false,
listing options={numbers=left,breaklines,basicstyle=\ttfamily,caption={Rust is Genshin Impact of coding},captionpos=t,label={mycode}},#1%
}

问 如何允许代码跨页 (breakable; across page) 并且让 caption 位于代码上方？
