Dear list,

I have the following sample:

    \useMPlibrary[txt]

    \starttext

    \startuseMPgraphic{followtokens}
     path RotPath ; RotPath := reverse halfcircle ;
     % path RotPath ; RotPath := halfcircle rotatedaround (origin, 180) ;
    \stopuseMPgraphic

    \followtokens{Just follow the tokens}
    \stoptext

How can I get both paths (in diverse directions)?

I would like to repeat the same text twice, separating both sentences
with a character.

I have to ask this, beause MetaPost is all Greek to me.
i have no clue what you mean but this will change the direction

Many thanks for your reply, Hans.

I attach an image of what I mean.

I want a full circle in two halves with the same duplicated sentence.
The first one written clockwise and the second one written
counterclockwise (as in the commented path above).

I hope it is clearer now.

    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 ;

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

we will have this in metafun:

    followtext("this way",p) ;

so that one can do it all in mp ... a nice gimmick for the ctx meeting

Hans
