How to use MPgraphic with options?

How to use MPgraphic with options?

[Wei-Wei Guo]

Dear all,

I need to use many rules with different lengths. Is there any way to implement
function like below:

   \startuniqueMPgraphic{ARule}{length}
   draw origin -- (\MPvar{length},0) ;
   \stopuniqueMPgraphic

   \uniqueMPgraphic[length=5mm]{ARule}

The example cannot be run. I only use it to explain what I want.

Any suggestion is appreciated.

Best wishes,
Wei-Wei

I think this is one way:

\startuseMPgraphic{ARule}
 draw origin -- (\MPvar{mylength},0) ;
\stopuseMPgraphic

\def\ARule#1{%
\setupMPvariables[ARule][mylength=#1]
\useMPgraphic{ARule}
}

\starttext
Foo \ARule{5mm} bar \ARule{10mm}
\stoptext

Best regards, Mikael
