tcolorbox 样式相互衍生

Question

该listing包允许轻松定义相互派生的样式和环境，这非常实用，可以避免复制和粘贴大量代码。我正在尝试了解如何使用 做同样的事情tcolorbox。

以下面的代码为例：

% Document class
\documentclass[letterpaper, 10pt, onecolumn]{article}

% Packages
\usepackage{calc}
\usepackage{xcolor}
\usepackage{listings}
\usepackage{lipsum}
\usepackage[most]{tcolorbox}

% Style
\newtcblisting{codebox}[4][\small]{
    before upper = {\topskip0pt \maxdepth=0pt},
    enhanced,
    listing only,
    breakable = unlimited,
    top = 0em,
    bottom = 0em,
    left = 0pt,
    right = 0pt,
    arc = 0em,
    outer arc = 0em,
    boxsep = 0em,
    boxrule = 0.5mm,
    titlerule = 0em,
    colback = white,
    colframe = blue,
    title = \centering#2,
    listing options = {
        language = C++,
        basicstyle = \fontfamily{cmtt}\selectfont#1,
        #3,
    },
    #4,
}
\newtcblisting{codebox*}[4][\normalsize]{
    before upper = {\topskip0pt \maxdepth=0pt},
    enhanced,
    listing only,
    breakable = unlimited,
    top = 0em,
    bottom = 0em,
    left = 0pt,
    right = 0pt,
    arc = 0em,
    outer arc = 0em,
    boxsep = 0em,
    boxrule = 0.5mm,
    titlerule = 0em,
    colback = white,
    colframe = black,
    title = \centering#2,
    listing options = {
        language = Python,
        basicstyle = \fontfamily{cmtt}\selectfont#1,
        #3,
    },
    #4,
}

% Document
\begin{document}
\lipsum[1]
\begin{codebox}{C++ listing example}{}{}
int main(int argc, char* argv[])
{
    return 0;
}
\end{codebox}
\begin{codebox*}{Python listing example}{}{}
def f(x):
    return x * x
\end{codebox*}
\lipsum[1]
\end{document}

定义了两个环境，codebox两者codebox*之间几乎没有什么区别（包括不同的默认参数）。是否可以有一种从另一种派生的方式，以避免复制和粘贴彼此接近的环境的所有选项。一个限制是，我希望用户端的界面保持不变（\begin{codebox}{}{}{}或\begin{codebox}[]{}{}{}）。

这就是样式的用途。此示例将公共键放入样式中common，两个框均使用该样式。

\documentclass[letterpaper, 10pt, onecolumn]{article}

% Packages
\usepackage{calc}
\usepackage{xcolor}
\usepackage{listings}
\usepackage{lipsum}
\usepackage[most]{tcolorbox}
\tcbset{common/.style={before upper = {\topskip0pt \maxdepth=0pt},
    enhanced,
    listing only,
    breakable = unlimited,
    top = 0em,
    bottom = 0em,
    left = 0pt,
    right = 0pt,
    arc = 0em,
    outer arc = 0em,
    boxsep = 0em,
    boxrule = 0.5mm,
    titlerule = 0em,
    colback = white,  
 }}

% Style
\newtcblisting{codebox}[4][\small]{common,colframe = blue,title = \centering#2,
   listing options = {
        language = C++,
        basicstyle = \fontfamily{cmtt}\selectfont#1,
        #3,
    },
    #4,
}
\newtcblisting{codebox*}[4][\normalsize]{common,
    colframe = black,
    title = \centering#2,
    listing options = {
        language = Python,
        basicstyle = \fontfamily{cmtt}\selectfont#1,
        #3,
    },
    #4,
}
