可以在 tcolorbox 列表中定义“样式”吗？

Question

只需使用\lstdefinestyle{foo}{ your options}并说listing options={style=foo}，这将节省大量的打字（或工作）。

设置样式后，您可以更改列表选项：

listing options={style=foo,numbers=right}，例如。

以下是修改后的 OP 代码

\RequirePackage{filecontents}
\begin{filecontents}{test.c}
#include <stdio.h>

int main() { 
    return 0;
}

\end{filecontents}

\documentclass{article}
\usepackage[listings, breakable, skins, fitting]{tcolorbox}

\lstdefinestyle{rmano}{      language          = {[Visual]C++},           % Language
      basicstyle        = \ttfamily,             % Default format          
      keywordstyle      = \color{blue},          % Keywordformat                               
      breaklines        = true,                  % Automatic line breaks
      breakatwhitespace = true,                  % Line breaks only at white spaces
      tabsize           = 4,                     % Number of spaces equal to a tab
      showspaces        = false,                 % Show spaces in the code
      showtabs          = false,                 % Show tabs in the code
      showstringspaces  = false,                 % Show spaces among strings
}

编辑

这是一个具有常用选项的版本tcolorbox：

使用

\def\commonboxoptions{    breakable,
    width=0.9\linewidth,
    bicolor,
    lower separated=true,
    colback=red!5!,
    colframe=red!75!black,
}

code={\pgfkeysalsofrom{\commonboxoptions}}并在选项中说tcolorbox（listing boxes这里！）

\RequirePackage{filecontents}
\begin{filecontents}{test.c}
#include <stdio.h>

int main() { 
    return 0;
}

\end{filecontents}

\documentclass{article}
\usepackage[listings, breakable, skins, fitting]{tcolorbox}

\lstdefinestyle{rmano}{      language          = {[Visual]C++},           % Language
      basicstyle        = \ttfamily,             % Default format          
      keywordstyle      = \color{blue},          % Keywordformat                               
      breaklines        = true,                  % Automatic line breaks
      breakatwhitespace = true,                  % Line breaks only at white spaces
      tabsize           = 4,                     % Number of spaces equal to a tab
      showspaces        = false,                 % Show spaces in the code
      showtabs          = false,                 % Show tabs in the code
      showstringspaces  = false,                 % Show spaces among strings
}

\def\commonboxoptions{    breakable,
    width=0.9\linewidth,
    bicolor,
    lower separated=true,
    colback=red!5!,
    colframe=red!75!black,
