\startQUESTION The following minimal example yields an error:
\starttext \startMPcode input circle ; \stopMPcode \stoptext
where circle.mp contains a btex...etex sequence:
draw fullcircle scaled 1cm ; label (btex 1 cm etex , (0,0)) ;
The "input circle ;" will work if I comment-out or remove label ; The minimal example will work, of course, if the mp code is in my tex file.
The error message is:
mplib : loading 'metafun.mp' (experimental metapost version two) ! mp terminal: (circle.mp
circle.mp circle.mpx ! Unable to make mpx file. l.2 label (btex 1 cm etex , (0,0));

hm, looks like I have to intercept the inputs in order to turn the btex ... into textexts (which happens with the main file) what I actually need for this is a reader hook (just like we have a finder hook); I could use the finder hook to make a temporary file, but I wonder if that makes sense so let's first check if we can get a reader hook (remind me in a few weeks anyway and use textext instead of btex/etex for the moment) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
