我有一个我指定的环境......
\begin{code}{TITLE}{LANGUAGE}{CAPTION}
\end{code}
我希望能够指定它，例如......
\begin{code}[title={TITLE},language={LANGUAGE},caption={CAPTION}]
\end{code}
当前环境的一个例子是......

在底层，选项tcblisting被处理为PGF 键。可选参数#1将其内容传递给code环境，这意味着我们可以传入我们自己的 PGF 键模块，我将其命名为codeFormattingKeys。我将这些可选键定义为title、language和caption。当您使用它们时，它们将调用应用了您的样式的预定义键tcblisting。
