xsim 的奇数垂直间距

Question

xsim我正在尝试使用基于预定义模板的一些自定义模板来编写以下文档：

\documentclass{scrartcl}%
\usepackage{lipsum}

\usepackage{xsim,mdframed}%
\xsimsetup{solution/print=true}
\DeclareExerciseEnvironmentTemplate{mtmargin}
{%  
    \trivlist
    \item[\llap{%
        \smash{%
            \tabular[t]{@{}r@{\hspace{.67em}}}
            {\large \sffamily \bfseries \GetExerciseProperty{counter}}
            \IfExercisePropertySetT{points}{%
                \tabularnewline
                \sffamily \itshape (%
                \printgoal{\GetExerciseProperty{points}}%
                \GetExercisePropertyT{bonus-points}{+\printgoal{#1}}%
                \,\XSIMtranslate{point-abbr}%
                )%
            }%
            \endtabular
        }%
    }]\relax
}%
{\endtrivlist}
\DeclareExerciseEnvironmentTemplate{mtrunin-sol}{%
    %\vspace{-1\baselineskip}     %% LINE 1
    \mdframed \noindent
    {\sffamily \bfseries \XSIMmixedcase{\GetExerciseName}.\hspace{1em}}%
}
{
    \endmdframed
    \par \vspace{\baselineskip}     %% LINE 2
}
\SetExerciseParameters{exercise}{
    exercise-template=mtmargin,
    solution-template=mtrunin-sol,
}





\begin{document}

\begin{exercise}[points=99]
    \lipsum[1]
\end{exercise}
\begin{solution}
    \lipsum[2]
\end{solution}
\begin{exercise}[points=99]
    \lipsum[3]
\end{exercise}
\begin{solution}
    \lipsum[4]
\end{solution}
\begin{exercise}[points=99]
    \lipsum[5]
\end{exercise}
\begin{solution}
    \lipsum[6]
\end{solution}

\end{document}

我在练习和解决方案之间得到了一个不必要的垂直空间，我不知道它从何而来。可以通过引入“LINE 1”（在上面的代码中已注释）轻松修复它，但这并不能仅通过创建补丁就将问题“控制住”。此外，如果我插入“LINE 2”，我得到的不是 而是\vspace{\baselineskip}大致\vspace{2\baselineskip}。有什么建议可以理解这种行为吗？这个问题与命令有关吗\trivlist？

Answer 1

是的，它就是trivlist。

您可以\topsep在开始之前将其设置为零\trivlist：

\DeclareExerciseEnvironmentTemplate{mtmargin}
{%
    \setlength{\topsep}{0pt}%
    \trivlist
    \item[\llap{%
        \smash{%
            \tabular[t]{@{}r@{\hspace{.67em}}}
            {\large \sffamily \bfseries \GetExerciseProperty{counter}}
            \IfExercisePropertySetT{points}{%
                \tabularnewline
                \sffamily \itshape (%
                \printgoal{\GetExerciseProperty{points}}%
                \GetExercisePropertyT{bonus-points}{+\printgoal{#1}}%
                \,\XSIMtranslate{point-abbr}%
                )%
            }%
            \endtabular
        }%
    }]\relax
}%
{\endtrivlist}

或者使用不同的策略，无需trivlist：

\DeclareExerciseEnvironmentTemplate{mtmargin}
{%
 \noindent\makebox[0pt][r]{\smash{%
            \tabular[t]{@{}r@{\hspace{.67em}}}
            {\large \sffamily \bfseries \GetExerciseProperty{counter}}
            \IfExercisePropertySetT{points}{%
                \tabularnewline
                \sffamily \itshape (%
                \printgoal{\GetExerciseProperty{points}}%
                \GetExercisePropertyT{bonus-points}{+\printgoal{#1}}%
                \,\XSIMtranslate{point-abbr}%
                )%
            }%
            \endtabular
        }%
    }%
}%
{}
