自动调整 tcolorbox 右侧的宽度 
\documentclass{article}
\usepackage[most]{tcolorbox}
\usepackage{mathtools}
\usepackage[lmargin=2cm,rmargin=2cm]{geometry}

\begin{document}

\begin{tcblisting}{title=Column Factorization,sidebyside, listing and comment,righthand ratio=0.35,
comment={
$\begin{array}{r|r}
1.500 & 2 \\
750 & 2 \\
375 & 3 \\
125 & 5 \\
25 & 5 \\
5 & 5 \\
1
\end{array} \quad \boxed{1.500 = 2^2 \cdot 3 \cdot 5^3}$
}}
To solve the exercise we use the method of decomposition into column.

$\begin{array}{r|r}
1.500 & 2 \\
750 & 2 \\
375 & 3 \\
125 & 5 \\
25 & 5 \\
5 & 5 \\
1
\end{array} \quad \boxed{1.500 = 2^2 \cdot 3 \cdot 5^3}$
\end{tcblisting}

\begin{tcblisting}{title=Find GCD and LCD,sidebyside, listing and comment,righthand ratio=0.45,
comment={
\begin{align*}
12 = 4 \cdot 3 &= 2^2 \cdot 3 \\
8 &= 2^3
\end{align*}
\[
   \text{GCD}(12, 8) = \boxed4 \qquad \text{LCD}(12, 8) = 8 \cdot 3 = \boxed{24}
\]
}}
The numbers are small so to calculate GCD and LCM it is better to use the mental decomposition.

\begin{align*}
12 = 4 \cdot 3 &= 2^2 \cdot 3 \\
8 &= 2^3
\end{align*}
\[
   \text{GCD}(12, 8) = \boxed4 \qquad \text{LCD}(12, 8) = 8 \cdot 3 = \boxed{24}
\]
\end{tcblisting}

\begin{tcblisting}{title=Tree diagram,sidebyside, listing and comment,righthand ratio=0.25,

\node[circle,draw,fill=orange!40!white,minimum size=0.7cm] (2) at  (9,9) {-};

The tree diagram shows the order of the operations and the numbers involved.

\begin{tikzpicture}
\node[circle,draw,fill=orange!40!white,minimum size=0.7cm] (1) at  (10,10) {+};
\node[circle,draw,fill=orange!40!white,minimum size=0.7cm] (2) at  (9,9) {-};
\node[circle,draw,minimum size=0.7cm] (3) at  (11,9) {2};

由于我必须编写大量的 tcolorboxes（特别是 tcblisting，以便获得并排源和输出效果如图这里），如果有办法可以自动调整右侧部分的宽度就好了，这样我就不用每次都手动调整了。

我尝试过这个选项hbox我尝试了建议的这里，但它同时调整了左右部分的宽度。

我也尝试过，但是由于页面的总宽度，righthand width=\linewidth它不起作用。\linewidth

因此要求是：

  • 有一个环境（tcblisting 或类似的），让我在一侧显示源代码+其他文本，在另一侧仅显示源代码的输出，即而不是“其他文本”；

  • 输出是数学和 tikz，因此必须支持equation、、、、等类似align的环境；\[ \]array$ ... $

  • 输出侧（通常是右侧）的宽度必须自动调整，这样就不需要righthand ratio=...每次都放置。

答案1

您可以tcbsidebyside从xparse库中使用sidebyside adapt选项。

% \tcbuselibrary{xparse} % in preamble
\tcbsidebyside[sidebyside adapt=right]{<left-hand content>}{<right-hand content>}

在此处输入图片描述

\documentclass{article}
\usepackage[most]{tcolorbox}
\tcbuselibrary{xparse}
\begin{document}

\tcbsidebyside[sidebyside adapt=right,]{
This is not a test This is not a test This is not a test This is not a test This is not a test This is not a test This is not a test
}{
\rule{1cm}{1cm}
}

\tcbsidebyside[sidebyside adapt=right,]{
This is not a test This is not a test This is not a test This is not a test This is not a test This is not a test This is not a test
}{
\rule{4cm}{4cm}
}

\end{document}

获得“并排源和输出效果”。

\begin{document}
\mysidebox[]{%

\mysidebox{%

}

\mysidebox[title=The Triangle]{%
\begin{tikzpicture}

一些天真的尝试。

\documentclass{article}
\usepackage[most]{tcolorbox}
\newbox\rightbox

\begin{document}
\tcbset{right
box/.style={/utils/exec={\setbox\rightbox=\hbox{\begin{tabular}{@{}l@{}}
#1
\end{tabular}}},righthand
width=\the\wd\rightbox,comment={\copy\rightbox}}}

\begin{tcblisting}{sidebyside, listing and comment,right box={$E=m\,c^2$}}
This is not a test This is not a test This is not a test This is not a test This is not a test This is not a test This is not a test
\end{tcblisting}

\begin{tcblisting}{sidebyside, listing and comment,right box={Errare humanum
est.\\ But I am a cat.}}
This is not a test This is not a test This is not a test This is not a test This is not a test This is not a test This is not a test
\end{tcblisting}

\begin{tcblisting}{sidebyside, listing and comment,right box={%
\includegraphics[width=3.14cm]{example-image-duck}}}
This is not a test This is not a test This is not a test This is not a test This is not a test This is not a test This is not a test
\end{tcblisting}

附录：这总结了我可以针对您下面的评论提供的内容。不幸的是，我不知道如何创建一个可能包含align环境的框，例如，事先不知道宽度。（如果知道宽度，这很简单，可以使用迷你页面，但这违背了这个问题的目的，或者至少违背了我的解释。）所以我所能做的就是提供一些环境，产生类似于align您给出的输出。

\documentclass{article}
\usepackage{amsmath}
\usepackage[most]{tcolorbox}
\newbox\rightbox
\newenvironment{myalign}{$\displaystyle\begin{aligned}}{\end{aligned}$}
\begin{document}
\tcbset{right box/.style={/utils/exec={\setbox\rightbox=\hbox{\begin{tabular}{@{}l@{}}
#1
\end{tabular}}},righthand width=\the\wd\rightbox,comment={\copy\rightbox}}}



\begin{tcblisting}{sidebyside, listing and comment,
right box={\begin{myalign}E&=m\,c^2\\
&=h\,\nu\end{myalign}}}
This is not a test This is not a test This is not a test This is not a test This is not a test This is not a test This is not a test
\end{tcblisting}

\begin{tcblisting}{sidebyside, listing and comment,right box={Errare humanum
est.\\ But I am a cat.}}
This is not a test This is not a test This is not a test This is not a test This is not a test This is not a test This is not a test
\end{tcblisting}

\begin{tcblisting}{sidebyside, listing and comment,right box={%
\includegraphics[width=3.14cm]{example-image-duck}}}
This is not a test This is not a test This is not a test This is not a test This is not a test This is not a test This is not a test
\end{tcblisting}

以下是我所做的，使我的颜色框自动调整到数学方程式的大小。

\documentclass[10pt,letterpaper]{article}
\usepackage[utf8]{inputenc}
\usepackage[most]{tcolorbox} % for colorboxes
\tcbuselibrary{listings,xparse,skins} % for \tcbsidebyside
\usepackage{lipsum} % dummy text

\begin{document}

%----- flexible split
% cannot adapt to equation environments unless inside $...$
\tcbsidebyside[
    title=Title Goes Here,
    sidebyside adapt=left, % we adapt to the size of the left content
    halign=flush center,
    halign lower=left,
    colback=white,
    colframe=black,
]{
    %----- left content
    %--- works
    $
        \begin{gathered} 
            \begin{aligned} 
                &x^2 - 2 \\ 
                &x^3 + x - \frac{1}{2}
            \end{aligned} \\
            x^2 + 3 \\ 
            x^3 - \frac{4}{2} + 2
        \end{gathered}
    $
    
    %--- doesn't work
    % \begin{gather*}
    %     x^2 - 3 \\ x^3 - \frac{4}{2}
    % \end{gather*}
}{
    %----- right content
    \lipsum[1]
}

\end{document}

结果
