当宽度未知时，如何仅调整线的一部分？

Question

此解决方案创建环境myformat以将保存框中\illustration指定的行数放入文本中。

值 2.2em 大约是问题所指的缩进量。我真的不想深入研究 exsheets 或 exbook 来确定精确的宽度。

\documentclass[a4paper,14pt]{extbook}

\usepackage[english,latin]{babel}
\usepackage{graphicx} \graphicspath{{plots/}}
\usepackage{tikz}
\usepackage{lipsum}% MWE only
\usepackage{showframe}% MWE only

\usepackage[auto-label,counter-within=chapter]{exsheets}

  \SetupExSheets{headings=runin}
  \DeclareInstance{exsheets-heading}{runin}{default}{
    runin = true,
    number-pre-code = \hspace{1em},
    number-post-code =~,
    join = { main[hc,vc]number[l,vc](0em,0pt) }
  }

\newsavebox{\illustration}% used to pass image
\newenvironment{myformat}[1]{% #1=line number for start of illustration (1=first)
  \begin{minipage}[t]{\dimexpr \linewidth-2.2em}% kludge
  \setlength{\dimen0}{\dimexpr \textwidth-\wd\illustration-\columnsep}% reduced line width
  \setlength{\dimen1}{\dimexpr \ht\illustration + \dp\illustration}% total height
  \count1=\numexpr \dimen1/\baselineskip\relax
  \ifdim \dimen1>\the\count1\baselineskip\relax
    \advance\count1 by 1
  \fi
  \count2=0% construct \parshape arguments
  \ifnum #1<2\relax
    \edef\shape{\the\numexpr \count1+1}%
  \else
    \edef\shape{\the\numexpr \count1+#1}%
    \loop\advance\count2 by 1
    \ifnum\count2<#1\relax
      \edef\shape{\shape\space 0pt \the\linewidth}%
    \repeat
    \count2=0
  \fi
  \loop\ifnum\count2<\count1
    \edef\shape{\shape\space 0pt \the\dimen0}%
    \advance\count2 by 1
  \repeat
  \edef\shape{\shape\space 0pt \the\linewidth}%
  \parshape=\shape
  \tikz[overlay]{\path ({\textwidth-\wd\illustration},{\ht\strutbox+\baselineskip-#1\baselineskip})
    node[below right, inner sep=0pt]{\usebox\illustration};}%
  \ignorespaces}{\end{minipage}}

\begin{document}

\savebox{\illustration}{\includegraphics[width=0.2\textwidth]{example-image}}%
\begin{question}[ID=1] \begin{myformat}{1}
\texttt{[some text here]}
\LipsumPar{1}
\end{myformat}
\end{question}

\begin{question}[ID=2] \begin{myformat}{2}
  \texttt{[another text]}
  \LipsumPar{1}
  \end{myformat}
  \end{question}

  \begin{question}[ID=3] \begin{myformat}{3}
  \texttt{[something else]}
  \LipsumPar{1}
  \end{myformat}
  \end{question}

\end{document}

除了 TikZ 之外，还可以使用

  \leavevmode\rlap{\hspace{\dimexpr \textwidth-\wd\illustration}%
    \raisebox{\dimexpr \ht\strutbox+\baselineskip-#1\baselineskip-\ht\illustration}[0pt][0pt]%
      {\usebox\illustration}}%

我将它们开发为完全独立的环境，然后弄清楚如何合并大部分代码。

棘手的是question包含\par和\parshape必须位于之后\par但位于其他内容之前。因此，就像wrapfig我使用的一样\everypar。

此版本不再需要缩进question，而是需要它使用的额外垂直间距（近似值）。
