So TeX sees no > macro '\\' which could expand to whatever. it depends on where you code lives ... in a lua file, then \\ is an escape, in \directlua (or \ctxlua cum suis), then it's a tex cs your mail only shows the one line of code so we have to guess >> there is a \luaescapestring primitive which catches things like >> quotes > > Can you make a little example of usage? > >> tex.print("\detokenize{$\sqrt{2}=}" .. math.sqrt(2) .. "$") well, if you put that in your document, you'l get a typeset tex.sprint, so i assume that tis is wrapped in \directlua or so? > Could not find the definition of \detokenize. an etex primitive ----------------------------------------------------------------- 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 ----------------------------------------------------------------- ___________________________________________________________________________________ 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 : https://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________
