我在文档中经常需要minted在环境中使用环境。我想编写一个新的环境来执行此操作，但由于它不设计为包含在其他环境中，因此我决定使用编写一个小补丁，基于
minipagemintedminted internals使用 minted 定义新环境我将这个补丁包含到我的主要文档中。但是，它似乎仍然不起作用。
错误信息：
Paragraph ended before \FV@BeginScanning was complete \begin{cppcode}[10.7cm]
有人能帮我找出我做错什么了吗？
这是“补丁”的代码。它重新定义了\newminted快捷方式命令以将minipage环境合并到自定义minted环境中，并使用几个嵌套条件来检查是否minipage提供了可选宽度。
\makeatletter
\DeclareDocumentCommand \newminted {o m m}
{
\IfNoValueTF {#1} % check if custom env. name is provided, and create new env. accordingly
{\def\minted@envname{#2code}}
{\def\minted@envname{#1}}
\DeclareDocumentEnvironment {\minted@envname} {o} % default env.
{ % begin definition
\IfNoValueTF {##1}
{ % minipage width not provided
\VerbatimEnvironment\begin{minted}[#3]{#2}
}
{ % minipage width provided
\VerbatimEnvironment
\minted@resetoptions
\setkeys{minted@opt}{#3}
\centering
\begin{minipage}{##1}
\begin{VerbatimOut}{\jobname.pyg}

{ % end definition
\IfNoValueTF {##1}

\end{minted}
}
{ % minipage width provided
\end{VerbatimOut}
\minted@pygmentize{#2}
\DeleteFile{\jobname.pyg}
\end{minipage}
}
}
\DeclareDocumentEnvironment {\minted@envname *} {m o} % custom env. name

Every literal has a type determined by its \textit{form} and \textit{value}
\subsubsection{Integer \& Floating Point Literals}
Integer literals can be represented using \textbf{decimal}, \textbf{octal}, or \textbf{hexadecimal} notations. Integer
literals that begin with \texttt{0} (zero) are interpreted as octal. Those that begin with either
\texttt{0x} or \texttt{0X} are interpreted as hexadecimal:
% Minipage width specified. NO on-the-fly options
\begin{cppcode}[10.7cm]
20 /* decimal */ 024 /* octal */ 0x14 /* hexadecimal */
\end{cppcode}
By default, decimal literals are signed. whereas octal and hexadecimal literals can either be signed or unsigned. Decimal literal has the smallest type of \keyw{int}, \keyw{long}, or \keyw{long long} in which the value fits. Octal and hexadecimal literals have the smallest type of \keyw{int}, \keyw{unsigned int}, \keyw{long}, \keyw{unsigned long}, \keyw{long long}, or \keyw{unsinged long long}
Floating-point literals include either a decimal point or an exponent specified using scientific notation. Using scientific notation, the exponent is indicated by either E or e:
% Minipage width specified. WITH on-the-fly options
\begin{cppcode*}{linenos=false}[6cm]
3.14159 3.14159E0 0. 0e0 .001

答案1
此代码可以稍微清理一下，但应该可以满足您的大部分需求。在没有强制参数的情况下，获取 verbatim 环境的可选参数总是很棘手。请参阅这以供参考。
我将您的环境重命名为，cpp这样我就不必深入研究minted内部结构，并将可选参数放在强制参数之前，这是很典型的。
