I used to pass (color) parameters to \startuseMPgraphic with:
\startuseMPgraphic{square}{acolor}
draw unitsquare withcolor \MPvar{acolor}; % or \MPcolor{acolor}
In both cases I get the following error:
metapost initializing instance 'metafun' using format 'metafun'
metapost loading 'metafun' as
'/Users/hansm/TeX/context-09/tex/texmf-context/metapost/context/base/metafun.mpiv'
using method 'default'
metapost initializing number mode 'scaled'
checkmissing or ungrouped '=' after 'green' in line '7
(442square:)'
Has something changed in this mechanism of parameter use, or am I doing
something wrong?
I don’t if you’re doing something wrong because you send only code snippets
which makes
it hard to tell where the problem lies.
\starttext
\startuseMPgraphic{square}{acolor}
draw unitsquare scaled 10 withcolor \MPvar{acolor} ;
\stopuseMPgraphic
\useMPgraphic{square}{acolor=red}
\useMPgraphic{square}{acolor=blue}
\stoptext
