actual path is constructed there and the text following the path should 
be on that page.

search for lmt_followtext in the luametafun manual

[NTG-context] Using \startuseMPgraphic inside a textext() in METAPOST?

[Gerben Wierda]

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.
