Hi (not yet back but back) Mojca,
PS: I don't dare to claim anything, but from my faint memories I think that metafun format doesn't regenerate once a new version of metapost comes out (I may be wrong, I would need to test, this really happens in extremely rare cases).
in mkiv i check the version when i load metafun but in mkii this cannot be done conveniently (at least not at the cost of much more runtime)
For mkii the above solution doesn't work in circumstances where I expected it to work (or maybe I don't understand how it's supposed to work), but I'll try to check later.
it should force a metafun remake whenever you remake a tex format Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
