xsim：使用自定义点进行垂直移动

Question

我内心改变了\DeclareExerciseEnvironmentTemplate{custom}{...}

\IfInsideSolutionF{\rule{1.2cm}{1pt}\slash}%

到

\IfInsideSolutionF{\noindent\usekomafont{sectioning}\color{pointscolor}}

我使用了一种计算点数总和的方法https://tex.stackexchange.com/a/494468/46023

为什么这里会出现几次垂直转变？

\documentclass[]{scrartcl}

\usepackage{xcolor}
\colorlet{pointscolor}{blue}

right=4cm,

%    grading-table/type      = exercise,
%}

\newcounter{expoints}
\newcommand{\addpts}[1]{%
    \addtocounter{expoints}{#1}%
    \SetExpandedExerciseProperty{points}{\theexpoints}%
    \marginpar[]{\color{pointscolor}\points{#1}}%
}
\xsimsetup{
    exercise/pre-hook       ={\setcounter{expoints}{0}}
}

Answer 1

您可以使用合适的模板定义来解决这个问题，其中 a)\marginpar在标题段落结束之前发出，并且 b) 其内容以\leavevmode自身开始（我没有研究为什么在使用颜色时后者似乎是必要的 - 顺便说一句：\usekomafont{sectioning}问题\normalcolor）。

下面我还删除了手动计算点数。有了最新的版本，就不再需要手动计算点数了xsim。

\documentclass{scrartcl}
\usepackage[
  showframe,
  left=2cm,
  right=4cm,
  marginparwidth=2.125cm
]{geometry}

\usepackage{xsim}
\usepackage{xcolor,needspace}
\colorlet{pointscolor}{blue}

\newcommand*\pointformat{\usekomafont{sectioning}\color{pointscolor}}
\newcommand*\addpts[1]{\marginpar{\leavevmode\pointformat{\addpoints{#1}}}}

\makeatletter
\DeclareExerciseEnvironmentTemplate{custom}
  {%
    \par\vspace{3.25ex plus 1ex minus .2ex}
    \Needspace*{3\baselineskip}%
    \noindent\usekomafont{sectioning}%
      \XSIMmixedcase{\GetExerciseName}\nobreakspace
      \GetExerciseProperty{counter}%
      \IfInsideSolutionF{%
        \GetExercisePropertyT{subtitle}
        { {\normalfont\itshape\PropertyValue}}%
      }%
    \GetExercisePropertyT{points}{%
      \marginpar{%
        \leavevmode\pointformat
        \printgoal{\PropertyValue}%
        \GetExercisePropertyT{bonus-points}{~(+\printgoal{\PropertyValue})}%
        ~\XSIMtranslate{points}%
      }%
    }%
    \par\vspace{1.5ex plus .2ex}
    \normalsize\normalfont
    \@afterindentfalse\@afterheading
  }
  {\par}
\makeatother
