Metafun manual section titles

Metafun manual section titles

[Romain Diss]

Hello,

I'm trying to make some section titles which look like the ones of the metafun 
manual: title and number underlined, with number in margin. I thougth it would 
not be too hard but I can't do it.

Actually, I'm using a frame with an overlay with a \startuniqueMPgraphic to 
underline the title but I can't make a frame for both the section number which 
is in the margin and the text which is not.

I tried to make the underlining of the title text extend in the margin but 
it's not easy because the frame background seems to be centered automatically 
on the frame. Maybe I should adjust some offsets but how can I know the size of 
the section number...

Anybody can help me on that problem ?

Hi,

you can try something like this:

\setuplayout[width=middle,backspace=4cm]

\startuseMPgraphic{line}
  drawoptions(withcolor \MPcolor{\framedparameter{framecolor}}) ;
  draw bottomboundary OverlayBox withpen pencircle scaled 3pt ; 
  setbounds currentpicture to OverlayBox ;
\stopuseMPgraphic

\defineoverlay[head:line][\useMPgraphic{line}]

\defineframedtext
  [framedHead]
  [align=right,width=fit,
   offset=overlay,boffset=.25ex,
   frame=off,framecolor=yellow:4,
   background=head:line]

\defineheadplacement
  [MyPlacement] [vertical]
  {\setwidthof{#1\hskip\leftmargindistance}\to\MyWidth\hskip-\MyWidth
   \startframedHead
     #1\hskip\leftmargindistance #2
   \stopframedHead}

\setuphead [chapter,section] [alternative=MyPlacement]

\starttext  \showframe
  \dorecurse{3}{
    \chapter{Chapter #1}
    \dorecurse{3}{\section{Section ##1}
      \dorecurse{3}{\subsection{Subsection}}
    }
  }
\stoptext

But I’m sure there are better solutions …

Best wishes
	Andreas

Thank you very much. It works perfectly! It take me some time to understand 
every line but the solution is quite nice. Context never stop to surprise me 
with all these "not so much documented" powerfull macros...
