I came up with:
\startluacode
user.Lookups = {
["Albano"] = "Albano (Provinz Rom)",
["Altona"] = "Altona (Hamburg)",
["Aurich"] = "Aurich (Ostfriesland)"
}
function user.Lookup(Name)
local Res = user.Lookups[Name]
if Res then
return context(Res)
else
return context(Name)
end
end
\stopluacode
\def\Ort#1{\index{\ctxlua{user.Lookup("#1")}}}
\starttext
\Ort{Albano}
\Ort{Altona}
\Ort{Aurich}
\strut\page
\placeindex
\stoptext
The lookup works so far, but all the entries get sorted unter C (because of
\ctxlua).
I remember I had the same problem with other macros (like \index{\emph{bla}}),
but can’t find a solution in my usual sources.
