Manipulating the pagenumber in the TOC

Manipulating the pagenumber in the TOC

Hi all,

"when manipulating in one area you will have to manipulate also in other aeras” I must confess.

I asked some time ago about manipulating the pagenumber. Wolfgang provide me the following approach:


\cldcontext{“\letterpercent.0f”,(\pagenumber+1)/2}

This works indeed fine. However now I am confronted with the fact, that in the TOC the manipulated pagenumbers should be taken into account. 

Wolfgang’s approach does not help and ends in an error:

\setupbodyfont[pagella,rm,10pt]

\setuppagenumbering[location=none,alternative=doublesided]


\startsetups Pagenumber
\doifoddpageelse
  {\cldcontext{"\letterpercent.0f",(\pagenumber+1)/2}}
	{}
\stopsetups

\setupfootertexts[\directsetup{Pagenumber}]
	
\setuppapersize[A6][A6]

\define[1]\SectionTOCPagenumber{%#1}
	\cldcontext{"\letterpercent.0f",(#1 +1)/2}}

\setuplist
	[section]
	[pagecommand=\SectionTOCPagenumber]
\stopmode
	
\starttext

\startsubject[title=Contents]
\placelist[section][criterium=all]
\stopsubject

\page

	\dorecurse{4}{
		\startsection[title=Ward-\recurselevel\hfill\pagenumber]
			\input ward\blank
		\stopsection
		\page}
\stoptext

\define[1]\SectionTOCPagenumber{
	\cldcontext{“\letterpercent.0f”,(\pagenumber+1)/2}}

\setuplist
	[section]
	[pagecommand=\SectionTOCPagenumber]

My question is: is there a way to manipulate the pagenumber in the TOC such, that it reflects the pagenumbers in the document?


Kind regards

Willi
