我的代码总行数大于页面的行数，在 minted 中，有一个breaklines选项，但它似乎换行超过了页行的长度。

有类似的问题，但这些答案不能解决我的问题。谢谢！
答案1
Minted 的内置框架非常有限。该软件包的文档说
如果您想要支持分页符和高级选项，您应该考虑使用框架包，例如 framed、mdframed 或 tcolorbox。
老实说，我真的不知道如何使用mdframed，所以我建议用 解决方案tcolorbox。
tcolorbox首先，使用minted和库进行加载breakable。我加载了xparse来定义一个用于铸造代码的框：
\usepackage[minted,xparse,breakable]{tcolorbox}
然后为铸造的代码创建一个列表框：
% [#1] - minted options
% #2 - language
% [#3] - tcolorbox options
\DeclareTCBListing{mintedbox}{O{}m!O{}}{%
listing only,% Prevent tcolorbox from trying to compile the code
breakable,% Allow page breaks
minted language=#2,% Make the mandatory argument be the language
minted options={% Pass these options to minted
linenos,
numbersep=5pt,
gobble=0,
tabsize=4,
breaklines=true,
mathescape,
framesep=2mm,#1},
% Appearance tweaks
top=0pt,% Remove borders
bottom=0pt,
left=0pt,
right=0pt,
arc=0pt,% Make the corners sharp
colframe=bg,% Make the frame the same color as the background
colback=bg,
coltitle=black,% Make the title black
#3}% And pass the options to tcolorbox
然后而不是
\begin{minted}[options]{language}
你用
\begin{mintedbox}[minted options]{language}[tcolorbox options]
这是你的 MWE：
