Hi ,

results in ! LuaTeX error [string "luas[0]"]:1: ')' expected near '\'.

This is with yesterday's svn.

well, it fails with any version, given that you have ~ defines as active char that expands to something \directlua 0 { if "ab" \string ~= "cb" then texio.write_nl("not equal") end } probably works ok at your end Hans ----------------------------------------------------------------- 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 -----------------------------------------------------------------

Hello,

\directlua 0{ if ("ab" ~= "cb") then do texio.write_nl("not equal") end end } \bye

results in ! LuaTeX error [string "luas[0]"]:1: ')' expected near '\'.

This is with yesterday's svn.

Try \directlua 0{\unexpanded{...}} \bye. \directlua expands its arguments completely, thus also expands the ~, which is active in at least PlainTeX, LaTeX and Context. @Taco: Perhaps a note in the manual about expansion in \directlua (and most likely \latelua) would be useful.
