I have a document with thousands of index entries. Here’s a sample code:
Some people lived in
\index{cliff-dwelling}\index{dwellings+cliff-dwelling}cliff-dwellings,
while others lived in \index{lean-to}\index{dwellings+lean-to}lean-tos.
I’m wondering if there is a short-cut means to set this up, such that if
I can tell the document that any time it sees “cliff-dwellings” in an
index, it will also add its page numbers to under
“dwellings+cliff-dwelling”? In other words, is there an easier way to
add these categories, then to go through the entire document and mark
them? I already have a list of all the words.
For instance, in my above code, I must find every \index{cliff-dwelling}
entry and add a \index{dwellings+cliff-dwelling} next to it...which
would take hundreds of hours if I did that for every word. Is there a
quicker way to tell it always also add it under "dwellings" too?
If it’s just a few instances, define a macro:
\define[1]\DwIndex{\index{#1}\index{dwellings+#1}#1}
For a list of words, a lookup table and a Lua function make sense.
With a comparable problem, normalizing location names, I used this:
-- lookups.lua
userdata = userdata or { }
userdata.Mapping = {
["Albano"] = "Albano (Provinz Rom)",
["Altona"] = "Altona (Hamburg)",
["Aurich"] = "Aurich (Ostfriesland)",
-- …
}
function userdata.Lookup(name)
context(userdata.Mapping[name] or name)
end
%%% environment
\loadluafile[lookups.lua]
\defineregister[Location][]
\define[1]\LocIndex{\expanded{\Location{%
\ctxlua{userdata.Lookup("#1")}}}}
