Hi,
this seems like a bug in the MetaFun or column set code. Printing a vertical rule between columns fails with
! terminal: >> NOfTextColumns-1 ! Improper final value has been replaced by 0. <to be read again>
The code also fails, when the column set code is commented out, but then the NOfTextColumns doesn't make sense any longer. Older betas work perfectly.
\startuseMPgraphic{verticalline} for i=1 upto NOfTextColumns-1 : draw (rightboundary TextColumns[i]) shifted (2.5mm,0) shifted -\MPxy\textanchor; endfor ; setbounds currentpicture to OverlayBox ; \stopuseMPgraphic
that (experimental) mechanism has been removed (maybe something else get in place, like regions we have already elsewhere)
\defineoverlay [verticalline] [\useMPgraphic{verticalline}] \setupbackgrounds [text] [background=verticalline] \definecolumnset [example] [n=2]
\starttext \startcolumnset [example] \input knuth \stopcolumnset \stoptext
I've added two column state variables to mp: \startuseMPgraphic{verticalline} if CurrentColumn < NOfColumns : draw rightboundary OverlayBox shifted (2.5mm,0) ; setbounds currentpicture to OverlayBox enlarged 2.5mm; fi ; \stopuseMPgraphic \definecolumnset [example] [n=3,background=verticalline,distance=5mm] \defineoverlay [verticalline] [\useMPgraphic{verticalline}] \starttext \startcolumnset [example] \input knuth \input knuth \input knuth \input knuth \stopcolumnset \stoptext ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
