The following specimen was run on live.contextgarden.net with each of the three typesetters:

\setupcolors[state=start] \starttext \input knuth

\input knuth \stoptext

In the case of pdfTeX and XeTeX, the table is given a width equal to the textwidth; in the caes of LuaTeX, it is typeset correctly with natural widths.

When \setupcolors is removed, both pdfTeX and XeTeX also produce the correct result.

This sounds like a bug to me (and took me forever to isolate \setupcolors - of all things! - as the culprit).

actually it's the \type (combined with colors) \dontleavehmode \type {xx} works ok probably some pdfliteral is playing havoc here so that the width analyer cannot function well (a limitation of tex is that there's only a small set subset of \un* and \last* node operations); if you see messages like this !!forced exit from shapebox 9!! that is indeed the case. hoewver, in mkiv i use different trickery so there we don't have this problem (we also use a different color mechanism so that helps too) it's not so much a bug in mkii as well as a side effect/limitation okay, we could add \dontleavehmode to \type but i'm not sure if that will not break other things; also, bTABLE is kind of tricky because it needs to be clever with regards to text and non text and such Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
