Many thanks for the reply, Hans.

I don’t know what I’m missing here, but I cannot get your code working.
Here you have the full sample:

  \useMPlibrary[txt]

  \starttext
  \startuseMPgraphic{followtokens}
     path p ; p := reverse halfcircle scaled 5cm ;
     path q ; q := reverse halfcircle scaled 5cm rotated 180 ;

     path q ; q := reverse halfcircle scaled 5cm rotated 180 ;
  \stopuseMPgraphic

  \followtokens{~this way~}
  \followtokens{\reversedtext{~this way~}}
  \stoptext

\reversedtext is undefined (I’m using beta from 2018.04.04 00:51).

But even commenting that second command, \followtokens seems to require
that path is named RotPath to be used the text. I get the standard line.

What am I doing wrong here?

This will be incredibly handy.

Many thanks for your help,

Pablo
