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
