\def\Ort#1{\index{\ctxlua{user.Lookup("#1")}}}
You have to expand the \index argument:
\define[1]\Ort{\expanded{\index{...}}}
Ah, I never know where to expand (tried \expanded\ctxlua).
\expanded needs a argument, i.e. \expanded{...}
Now,
\def\TOrt#1{\expanded{\Ort{\ctxlua{userdata.Lookup("#1")}}}#1} % Loc + Text
\defineprocessor[kursiv][style=italicface]
\def\TFOrt#1{\expanded{\Ort[kursiv->]{\ctxlua{userdata.Lookup("#1")}}}#1} % Loc
in Footnote + Text
works. :)
(I always define \TIndex to avoid doubling, e.g. Hamburg\index{Hamburg}.)
When you use formatting commands etc. you have to use the optional argument for
sorting.
I don’t understand.
\Ort[kursiv->]{Hamburg} works.
You mentioned only \index{\emph{...}} in your mail ...
You can avoid a few problems when you move the \index command to Lua and use
context.index or you use a pure TeX solution.
%%%% begin lua example
function userdata.index(name)
local indexentry = userdata.lookup[name] or name
context.index(indexentry)
end
That’s nice, but since I use different registers, I’d need to define that
function for each. Since I also use several shortcuts (e.g. \TOrt, \TFOrt,
\TPerson, \TFPerson) I would multiply the effort on the Lua side.
I find my TeX definitions (like above) shorter, where I can use the same Lua
function for each.
With your code I could at least shorten it to:
function userdata.Lookup(name)
context(userdata.Lookups[name] or name)
end
%%%% begin tex example
Oh, this is also nice. But isn’t the Lua version faster? (I have >600 person
entries and a few hundred locations).
Hard to say without testing but the difference can be ignored because
\index itself is what take processing time.
