Hi Hans,

Thanks for your attention, your quick response and the hints, especially regarding the definition of a command with brackets.

Indeed, as you may see with the following modified example, context.goto("Index",{"ref:index"}) generates an error, maybe because of a delimiter issue with the definition of \goto. However, after defining a \MyGoTo command with delimiters being explicitely brackets, then context.MyGoTo({"Index"},{"ref:index"}) works fine, as well as local s,t = "Index","ref:index" context.MyGoTo({s},{t}) so that my problem is solved…

Best regards: OK %% begin test-lua-reference.tex \setupinteraction[state=start] \def\MyGoTo[#1][#2]{\goto{#1}[#2]} \starttext

\startchapter[title={Ward},reference={ch:ward}]

\startluacode context.index("Knuth") context.index("Ward") context("Read Knuth and see also the ") local s,t = "Index","ref:index" context.MyGoTo({s},{t}) -- context.goto("Index",{"ref:index"}) -- this does not work \stopluacode

you need to use context["goto"]("Index",{"ref:index"}) -- this does not work because "goto" is a reserved lua word you can't say foo.if or foo.end either

\input ward.tex

\stopchapter

\starttitle[title={Index}] \startluacode local s,t = "ref:","index" context.pagereference({"ref:index"}) \stopluacode \placeindex \stoptitle

\stoptext %% end test-lua-reference.tex ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki!
