Hello list,
How can I call the \followtokens macro (or a similar solution) from
within metapost? Specifically, I want to integrate text between the
semi-circle arcs in a rainbow-like structure (with the text placed
inbetween the arcs, that should alsó be drawn). The text should not be
stretched but center on the top, flowing evenly distributed on each
side. This link will give you an idea:

How can this achieved?
a bit clumsy but workable
\starttext
\useMPlibrary[txt]
\startsetups text-a
\startuseMPgraphic{followtokens}
path RotPath ; RotPath := reverse halfcircle xyscaled 5cm ;
draw RotPath ;
\stopuseMPgraphic
\followtokens{some text but not that long{\hskip1em}}
\stopsetups
\startsetups text-b
\startuseMPgraphic{followtokens}
path RotPath ; RotPath := reverse halfcircle xyscaled 3cm ;
draw RotPath ;
\stopuseMPgraphic
\followtokens{{\hskip1em}some text{\hskip1em}}
\stopsetups
\startMPpage
draw textext("\setups{text-a}") ;
draw textext("\setups{text-b}") shifted (0,-.5cm);
\stopMPpage
\stoptext
