I am in METAPOST which is inside TeX and I’d like (in METAPOST, not in TeX) to
let a string follow a path. Adapting from the MetaFun manual around page 250, I
tried this:
\starttext
\startMPpage[instance=doublefun]
pic p;
p := textext("\startuseMPgraphic[instance=doublefun]{followtokens}path RotPath
; RotPath := fullcircle ;\stopuseMPgraphic\followtokens{I am creating a line of
text here}");
draw pic;
\stopMPpage
\stoptext
But that does not work. Is there a way I can from within my METAPOST code get
string (TeX code) to follow a path I have? In my case, I cannot escape outside
the \startMPpage- -\stopMPpage environment, as the actual path is constructed
there and the text following the path should be on that page.
