Hi all:

I would like to draw a short horizontal line, somewhat like \hl[5] but dashed instead of solid. Is there a command for this?

you can do that with \leaders in tex code, but nicer is:


\startuniqueMPgraphic{WhatARule}{length,linewidth,color}
  draw
    origin -- (\MPvar{length},0)
    dashed evenly % change this to what you want
    withpen pencircle scaled \MPvar{linewidth}
    withcolor \MPcolor{\MPvar{color}} ;
\stopuniqueMPgraphic

\setMPvariables
  [WhatARule]
  [length=6\bodyfontsize, % 4cm,
   linewidth=1pt,
   color=red]

\def\WhatARule
  {\dontleavehmode\struttedbox{\uniqueMPgraphic{WhatARule}}}

\starttext

\dostepwiserecurse{4}{12}{1}
  {\expanded{\switchtobodyfont[\recurselevel pt]}
   test \par \WhatARule \par test}

\stoptext
