This gives an error: \starttext \setupbars[rulethickness=4pt] \stoptext ! LuaTeX error <main ctx instance>:1: malformed number near '4pt'. ConTeXt ver: 2012.07.04 23:48 MKIV fmt: 2012.7.6 int: english/english Elsewhere this is ok, as for example in: \framed[rulethickness=4pt]{} Strangely in node-rul.mkiv I see: \c!rulethickness=2.5 whereas in pack-rul.mkiv: \c!rulethickness=\linewidth I am inclined to spot an error here, or at least an inconsistency in the API.

Thansk, I see. \setupbars doesn't give a hit on ConTeXt-wiki, so I couldn't find this. Still I dare say, it is a pity that [rulethickness=] gets a different meaning here than elsewhere. I would like to ask to reconsider, because I strongly believe in consistency in the API (though I am ready to admit that it is not easy to maintain and confess guilty myself at more than one occasion). That is either change all rulethickness's everywhere to this scheme or otherwise. Or did this already happened and did I miss that? And of course, the easiest solution would be if the code itself could sort out the difference between having been given a fraction or a length.

There is still an issue here. \setupbars[unit=mm,rulethickness=1] AB\startbar[underbar]CD\stopbar EF\crlf \setupbars[unit=ex,rulethickness=1] AB\startbar[underbar]CD\stopbar EF\crlf \setupbars[unit=pt,rulethickness=1] AB\startbar[underbar]CD\stopbar EF\crlf The first and third setup do not give an underbar, the second does. Question: why does "ex" qualify as a dimension unit but "pt" and "mm" do not? Sounds strange. If I want an underbar exactly 1mm or 3pt's thick, why isn't that made possible? Doing the math myself is no option, becaus ex will not be known beforehand.

The underlying Lua code accepts only “ex” and “em” as valid options for the “unit” key but I would also vote to accept either “pt”, “mm” etc. as unit value or to allow “rulethickness=…pt”. Wolfgang

actually it does accept more units but they were pretty small (needed an 1/u) anyhow, in the next beta we can do \starttext \setupbars[unit=mm,rulethickness=1] bar\startbar[underbar]foo\stopbar bar\blank \setupbars[unit=ex,rulethickness=1] bar\startbar[underbar]foo\stopbar bar\blank \setupbars[unit=pt,rulethickness=1] bar\startbar[underbar]foo\stopbar bar\blank \setupbars[unit=pt,rulethickness=10pt] bar\startbar[underbar]foo\stopbar bar\blank \stoptext but someone has do document it ----------------------------------------------------------------- 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 -----------------------------------------------------------------

the unit is uses for consistent stacking of nested bars; in the case of a unit with rulethickness that one is used for the rules, otherwise the general unit is applied to the rulethickness Hans ----------------------------------------------------------------- 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 -----------------------------------------------------------------
