Hello,
how to detect which language set by \mainlanguage[xy] is active?
How to detect it by a) ConTeXt and b) Lua?
Something like:
\mainlanguage[cz]
\ifmainlanguage{cz}
  Do someting
\fi
and
if context.languages.active() == "cz" then
  -- Do somthing
end
You can use the modes mechanism for this because you can use **<TAG> to
check for the main language (set by \mainlanguage) and *<TAG> for the
current language (set by \language).
\mainlanguage[cs]
%\language[en]
\starttext
\doifelsemode{**cs}{The main language is Czech.}{The main language is
“\currentmainlanguage”.}
\startluacode
if tex.modes["**cs"] then
     context("The main language is Czech.")
else
     context("The main language is “\\currentmainlanguage”.")
end
\stopluacode
\blank
\doifelsemode{*cs}{The current language is Czech.}{The current language
is “\currentlanguage”.}
\startluacode
if tex.modes["*cs"] then
     context("The current language is Czech.")
else
     context("The current language is “\\currentlanguage”.")
end
\stopluacode
\stoptext
