I'll just keep watching. if you want to use external engines ... use xetex instead of luatex the whole idea behind luatex is that we have a configureable and programmable engine ... doing some script is not so much an issue (and we can do it more flexible once we have the machinery in place) but information is needed ... also, as we want tex cum suis to be flexible on the one hand and stable on the other, depending on hidden or fuzzy features in en uniscribe engine might not be the best idea in the oriental tex project we've spend quite some time on high quality arabic and i'm sure that we could not have come this far if we had wrote the code from scratch (all this font technology is not as open as the name suggest) ... also, there's more in mkiv than shown so far (esp in that area) for those experiments 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 ----------------------------------------------------------------- ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________
