允许在 tcolorbox 之后继续段落

Question

我使用tcolorboxes，有时希望它们成为较大段落的一部分，也就是说，我希望后面的文本tcolorbox不缩进。但是，\noindent和都\@afterheading存在一些缺陷（请参阅 MWE 中的注释）。

如何才能避免出现tcolorbox这些缺陷？我也不想失去默认提供的良好间距（即/tcb/beforeafter skip balanced）。

\documentclass{article}

\usepackage{tcolorbox}

\makeatletter

% This leads to extra spacing before a heading.
%\AddToHook{env/tcolorbox/after}{\noindent\ignorespaces}

% This leads to reduced spacing before a heading as well as
% not allowing new paragraphs after the environment.
% It also prevents page breaks, which I do not want.
%\AddToHook{env/tcolorbox/after}{\@afterheading}

\begin{document}

\section{Indentation after Boxes}
Here's a box followed by a heading.
\begin{tcolorbox}
  This box is followed by a heading.
\end{tcolorbox}

\subsection{A Heading}
Here's a box that is part of a paragraph
\begin{tcolorbox}
  This box should not lead to indentation of the following line.
\end{tcolorbox}
and should not cause indentation in this line.

And here's a box at the end of its paragraph.
\begin{tcolorbox}
  This box is followed by a new, indented paragraph.
\end{tcolorbox}

This is a new paragraph.

\end{document}

Answer 1

\@endparenv将每个列表环境都使用的附加到/tcb/after似乎有效。

更新：对于可破坏的盒子，增加了一些实验尝试。

\documentclass{article}
\usepackage{lipsum}
\usepackage{tcolorbox}
\tcbuselibrary{hooks, breakable}

\makeatletter
\tcbset{
  after app={%
    \ifx\tcb@drawcolorbox\tcb@drawcolorbox@breakable
    \else
      % add only when not breakabel
      \@endparenv
    \fi
  }
}

% for breakable
\appto\tcb@use@after@lastbox{\@endparenv\@doendpe}
\makeatother

\begin{document}
\section{Indentation after Boxes}
Here's a box followed by a heading.
\begin{tcolorbox}
  This box is followed by a heading.
\end{tcolorbox}

\subsection{A Heading}
Here's a box that is part of a paragraph
\begin{tcolorbox}[title=Unbreakable]
  This box should not lead to indentation of the following line.
\end{tcolorbox}
and should not cause indentation in this line.

Here's a box that is part of a paragraph
\begin{tcolorbox}[title=Breakable but not broken, breakable]
  This box should not lead to indentation of the following line.
\end{tcolorbox}
and should not cause indentation in this line.

Here's a box that is part of a paragraph
\begin{tcolorbox}[title=Breakable and broken, breakable]
  \lipsum[1-2]
\end{tcolorbox}
and should not cause indentation in this line.

And here's a box at the end of its paragraph.
\begin{tcolorbox}
  This box is followed by a new, indented paragraph.
\end{tcolorbox}

This is a new paragraph.

\end{document}
