Hello all, how to call \let from within Lua? I'd need to "\let\T=4" using Lua. The following code doesn't work (not so surprisingly): ---- \startluacode a = 4 \stopluacode \expandafter\let\expandafter\T=\cldcontext{a} \starttext Test \T. \stoptext ---- What's the correct way? TIA. Lukas -- Ing. Lukáš Procházka [mailto:LPr@pontex.cz] Pontex s. r. o. [mailto:pontex@pontex.cz] [http://www.pontex.cz] Bezová 1658 147 14 Praha 4 Tel: +420 244 062 238 Fax: +420 244 461 038

why let and not context.setvalue("T","4") anyway ... \startluacode a = 4 \stopluacode \normalexpanded{\let\noexpand\T\cldcontext{a}} \starttext Test \T. \stoptext ----------------------------------------------------------------- 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 -----------------------------------------------------------------

You need more \expandafter because \cldcontext needs two expansion steps: \expandafter\expandafter\expandafter\let\expandafter\expandafter\expandafter\T\expandafter\expandafter\expandafter=\cldcontext{a} but I wonder why you don use \def or \edef: \edef\T{\cldcontext{a}} Wolfgang

... OK, thank you, Hans & Wolfgang, for your responses. Best regards Lukas -- Ing. Lukáš Procházka [mailto:LPr@pontex.cz] Pontex s. r. o. [mailto:pontex@pontex.cz] [http://www.pontex.cz] Bezová 1658 147 14 Praha 4 Tel: +420 244 062 238 Fax: +420 244 461 038
