Hello, Anybody know how I can set variable in tex? For example \count10=20 \def\proste{To jest prosty napis} a\directlua{tex.print(tex.count[10]+5)}b a\directlua{tex.set("\proste","Trudne")}b \proste \bye I need setup \proste definition to my own string How I can read TeX variable \mynumber from lua and set variable \mynumber on TeX but set in lua script. Thanks Janusz Biznesu

Interestingly, token.set_macro allows defining macros whose replacement text has unbalanced braces. \directlua{token.set_macro("MyMacro", "\string{")} \expandafter\show\MyMacro \bye Bruno

Indeed. No expansion and parsing is involved except for one level checking of catcodes and tokens. This function is mostly there for simple usage like storing a string or so (no support for parameters etc). A bit like: \edef\foo{\noexpand\scantextokens{\string{}} \edef\oof{\noexpand\scantextokens{\string}}} test \foo\bf bar\oof\ test Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
