Hi all,

I would like to use the title and the number of a section twice :
- first with a specific layout (with makeup)
- second, as usual, as part of the page flow.

like in : http://www.pragma-ade.nl/general/manuals/cont-enp.pdf#page=23

looking at the source code 
(http://context.aanhet.net/svn/manuals/context/layo-00.tex), I 
understood that it was achieved with :

\setuphead
   [\v!chapter]
   [\c!command=\PlaatsHoofdstuk,
    \c!page=\v!yes,
    \c!before=,
    \c!inbetween=\PlaatsHoofdstukIndex,
   %\c!incrementnumber=cont-\currentlanguage,
    \c!header=\v!nomarking,
    \c!textstyle=\bfd,
    \c!numberstyle=\bfe]

and

\def\PlaatsHoofdstukIndex % todo: lucida
  {%\startnotmode[*\v!frontpart]
     \page[\v!right]
     \setupbackgrounds[\v!paper][\c!background=\v!color]
     \startmakeup[\v!standard]
       \raggedleft
       \doifsomething{\currentheadnumber}
          {\hfill\expanded{\processMPheadnumber{\currentheadnumber}}}
       \vfill
       \hfill\expanded{\processMPheadtext{\currentheadtext}}
     \stopmakeup
     \setupbackgrounds[\v!paper][\c!background=]
   }%\stopnotmode}



But currently, I can not reproduce it :
- \currentheadtex return empty
- \namedstructurevariable{section}{title} only report the update title
   once the title is actually typesetted

Is there a way to access \namedstructurevariable with [next] or 
[previous] like options ?


Here is a test trying to reproduce cont-enp.pdf example
===================================================

\def\CheckA{{\mono\currentheadtext}}
\def\CheckB{{\mono\namedstructurevariable{section}{title}}\page}

\setuphead
   [section]
   [before={before : \CheckA - \CheckB},
   inbetween={inbetween: \CheckA - \CheckB},
   after={after: \CheckA - \CheckB},
   beforesection={beforesection: \CheckA - \CheckB},
   insidesection={insidesection: \CheckA - \CheckB},
   aftersection={aftersection: \CheckA - \CheckB},
   color=darkred,
   style=\tfc,
   ]

\starttext

\startsection[title=Section A]
Text of section A.
\stopsection

\startsection[title=Section B]
Text of section B.
\stopsection

\stoptext

===================================================

Thanks for your help
Garulfo

Got a solution, but it looks like "not a proper way to do it"

Is it recommanded to work directly with lua tables like these :
- structures.sections.current().references
- fonts.current().specification

===================================================

\def\CheckC%
{\startluacode
local numero = structures.sections.current()
if numero == nil then
     numero = 1
else
     numero = structures.sections.current().references.listindex + 1
end
context.page()
context("inbetween : "..structures.lists.collected[numero].titledata.title)
context.page()
\stopluacode}

\setuphead [section] 
[color=darkred,style=\tfc,inbetween={\mono{\CheckC}}]
\setuphead [subsection] [inbetween=]

\starttext

     \startsection[title=Section A]
     Text of section A.

         \startsubsection[title=SubSection A.A]
         Text of subsection A.A
         \stopsubsection

     \stopsection

     \startsection[title=Section B]
         Text of section B.

         \startsubsection[title=SubSection A.A]
         Text of subsection A.A
         \stopsubsection

     \stopsection

\stoptext
