Re: [NTG-context] consistent index entries

1 Aug 2020

      Wrt formatting (e.g. \index{\emph{something}}), the garden also mentions
processors for MkIV (https://wiki.contextgarden.net/Registers#Processors),
so you can wrap them with custom commands, in case it helps.

Cordially,

Jairo.

Hi, Henning. According to the garden, something like:
\def\Ort#1{\index[#1]{\ctxlua{user.Lookup("#1")}}}
as long as #1 is capable of being sorted in the normal way, should work.
Regards,
Jairo

Hi,
besides the CG journal I’m working on a scientific biography with huge
person and locality indexes (named Person and Locality for the examples).
In many cases, the author wants additional information in the index,
e.g.
\Locality{Altona (Hamburg)}
\Locality{Breslau (pol. Wrocław)}
or
\Person{Arends, Katharina (née Schoemaker)}
\Person{Wilhelm II. (Kaiser)}
Now, I need that consistent and I don’t want to type these complicated
entries every time.
I’m looking for a good way to handle this – maybe a lookup table in
Lua, so that
\LookupPerson{Willy II}
would call a Lua function that returns
\Person{Wilhelm II. (Kaiser)}
?
Or is there already something in place that I overlooked, like
\OverwriteIndexEntry{Hraban}{Ramm, Henning Hraban}
?
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.
