Hi all,

Is there a ConTeXt equivalent to LaTeX \settowidth{}, or better still some macro I can do things like

\setupsomething[ ... width={\widthof{\bf sometext\emspace}}, ...]

Cheers,

Robin

Hi Robin,

I don't know if there is something build in but the following definition should work for simple cases.

\def\widthof#1% {\bgroup \setbox\scratchbox\hbox{#1}% \the\wd\scratchbox% \egroup}

\starttext

\getrawparameters [robin] [width=\widthof{Robin Kirkham}]

\robinwidth

\stoptext

this will typeset ok, but not with \dimen0=\robinwidth \def\setwidthof#1\to#2% {\bgroup \setbox\scratchbox\hbox{#1}% \expanded{\egroup\def\noexpand#2{\the\wd\scratchbox}}} \starttext \setwidthof{Robin Kirkham}\to\whatever \getrawparameters [robin] [width=\whatever] \robinwidth or so (untested) -- ----------------------------------------------------------------- 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 -----------------------------------------------------------------
