tcolorbox，lstlisting 即使对于 TeX 源也默认有悬挂缩进？

梅威瑟：

\documentclass{article}

\usepackage{tcolorbox}
\tcbuselibrary{listings}

\tcbset{
  codefullblock/.style={
    listing only,
    listing options={
      language=TeX, style=tcblatex, texcsstyle=*\color{blue}\bfseries
    }}
}

\newtcblisting{mycodeblock}{
  codefullblock
}

\begin{document}

Try this MWE:

\begin{mycodeblock}
\documentclass{article}
\begin{document}
\TeX is a control word.

Since a control word is ended by any non-letter, the space at the end of the control word for \textbackslash TeX is not typeset as a space. Instead, it is absorbed to indicate the end of that control word.

You'll notice that the backslash control word is similarly ended by a space, and that space is not typeset as a space.

The right way to type the above sentence would be:

\TeX\ is a control word.
\end{document}
\end{mycodeblock}

\end{document}

通常，listings 会逐行逐字读取并打印输入。在您的示例中，行很长，因此它们被打断以适合页面。为了标记断行的延续，后续行会缩进 20pt（这是 的默认值listings，我没有检查tcolorbox它是否会改变）。可以使用以下命令关闭此缩进breakindent=0pt,

\documentclass{article}

\usepackage{tcolorbox}
\tcbuselibrary{listings}

\tcbset{
  codefullblock/.style={
    listing only,
    listing options={
      language=TeX, style=tcblatex, texcsstyle=*\color{blue}\bfseries,
      breakindent=0pt,
    }}
}

\newtcblisting{mycodeblock}{
  codefullblock
}

\begin{document}

\begin{mycodeblock}
