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)
