使用 tcolorbox 包的列表，没有 Chapter 和 Section 环境效果

Question

我想listings使用tcolorbox包但不使用计数Chapter和Section环境。参见 MWE，我section在列表中使用了环境，这会影响以下部分的计数器。如果有人能帮助我 listings使用tcolorbox包但不使用计数Chapter和Section环境，我将不胜感激。谢谢

Answer 1

这会存储当前节计数器并在列表环境之后恢复它。在内部，节计数器会重置，以便输出列表。

\usepackage{listings}
\usepackage{tcolorbox}
\tcbuselibrary{listings}%
\usepackage{xcolor}

\lstset{ % General setup for the package

    basicstyle=\small\sffamily,
    numbers=left,
    numberstyle=\tiny,
    frame=tb,
    tabsize=4,
    columns=fixed,
    showstringspaces=false,
    showtabs=false,
    keepspaces,
    commentstyle=\color{red},
    keywordstyle=\color{blue}
}%

改良版

\PushCounterValues此版本在环境启动之前通过命令存储所有分段计数器（部分....子段落），然后tcblistings在环境启动之后恢复它们。

这样，任何内部的section 命令不会破坏文档计数器值。

\newtcblistingsenvironment如果使用自定义的话，这可以简化...
