How to avoid the extra-space when Lua > generates math subscript? actually, the luacode was doing the right thing as there is a = protect/unprotect mismatch (will be fixed); putting this at the top of = you file works: \catcodetable\ctxcatcodes I have no clue yet where the space comes from (that's taco's speciality) 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 t= he Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-cont= ext webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________= ________
