Help with Complex Array.

I don't have an answer for you, but after glancing through this, my brain is screaming "anonymous closure".

Not sure that will do anything, though

Lua is odd, but this code just bothers me at a gut level.

Code:

Harvest.DataStore = {
        ["alikr"] = Harvest.DataStore[Harvest.langs]["alikr"],
        ........
}

It's storing a table reference at that point. Not sure if that'll actually work as a SV result (if that's what it is).

The answer to 'how do I store this info' will largely rest on the question "What are you doing with the info?"

Note that you can store the information as sparsely as you need for storage purposes, and recombine them in game for speed of reference and create lookup tables and the like.

I am going to try this Lua console from source forge, no idea how to use it yet though. ^_^

Does anyone know a good Lua console that is easy to run like Python and Ruby?

Lua Code:

Harvest.langs = { "en", "de", "fr", }
 
Harvest.woodworking = {
    ["en"] = {
        "Ashtree",
        "Beech",
        "Birch",
        "Hickory",
        "Mahogany",
        "Maple",
        "Nightwood",
        "Oak",
        "Yew",
    },
    ["de"] = {
        "Eschenholz",
        "Buche", -- "Buchenholz"
        "Birkenholz",
        "Hickoryholz",
        "Mahagoniholz",
        "Ahornholz",
        "Nachtholz",
        "Eiche",
        "Eibenholz",
    },
    ["fr"] = {
        "Frêne",
        "Hêtre",
        "Bouleau",
        "Hickory",
        "Acajou",
        "Érable",
        "Bois de nuit",
        "Chêne",
        "If",
    },
}
 
function Harvest.IsValidWoodworkingName(name)
    local nameMatch = false
    for lang, langs in pairs(Harvest.langs) do
        for k, v in pairs(Harvest.woodworking[langs]) do
            if v == name then
                nameMatch = true
            end
        end
    end
 
    return nameMatch
end

That all works fine, so I have to build off of it and try to apply it to what I want with the map names.

Just as a note, you can escape early from that loop by using return true as soon as you have a match and return false outside the loop.

                {"cahute de Cadwell^fd", 2 },
            },
        },
    },
}

If you click the spoiler, as you can see I need to make it modular or I'll end up with a wall of text. Each map file is already over 1200 lines long.

Two things 1) I want to pass the map name, "cahute de Cadwell^fd" as an argument to a function and return the zone, subzone, and an index number. Then use string.format to end up with "coldharbor/coldharbour_base". The index would be that it was the 5th map name in the array. 2) Pass the zone, subzone, and the index and get the map name of any of the three languages thus ending up with a way to translate "cahute de Cadwell^fd" to "Cadwell's Hovel".

Lua Code:

Harvest.DataStore_en_auridon_base
Harvest.DataStore.en.auridon.base

Ok I am confused. What is the difference between the two lines. ESO told me I was trying to access a nil value with the line that has the dots in it. Do this dots make Lua think it's a function? The other line works.

The second are table references, the first is a single variable.

Essentially:

Code:

Harvest.DataStore.en.auridon.base

is

Code:

Harvest = {}
Harvest["DataStore"] = {}
Harvest["DataStore"]["en"] = {}
Harvest["DataStore"]["en"]["auridon"] = {}
Harvest["DataStore"]["en"]["auridon"]["base"] = {}

Code:

Harvest.DataStore_en_auridon_base

is

Code:

Harvest = {}
Harvest["DataStore_en_auridon_base"] = {}

You have to create the table before you can add further items to it otherwise you'll get a nil reference.

I suggest you read up on Lua, PiL is a good resource to learn the syntax of Lua

Yes. That way, if there's a match, it doesn't bother checking the rest of the tables.

As for your requirements, there are two ways you can go about it, depending on how often the information is requested.

If the requests are relatively scarce, you can do as you do above, and just create functions that loop through the tables, til you find a match, then create a chunk of info for your use.

If you need more speed, ie, your requests are very very often, you can create lookup tables in memory so that when you reference MapName["Aldunz"] it'll return { [Zone] : "alikr", [lang] : "en", [subzone] : "alikr_base", [map] : "Aldunz"}. This will frontload the work, by doing it all at load, but will speed up lookup. You just need to know what information you're using, and what format you need the result in.

I advise you read up on how Lua handles tables and references first though, so you understand just what sort of structures you're creating.

That is good advice. Since you probably know more then I, does this page seem to you like it would explain it well enough? Do you think it's missing what you were trying to explain about a "lookup tables"? What do you think? I wont need to remove, insert, or sort the table because it will remain constant.

Unless I'm not completely reading this thread, you can vastly simplify your code by only loading the language file(s) the client has currently running. You do this in your manifest by using the $(language) variable. At run-time the launcher will pick. That way you are also using less memory, your search index can be in your native language, and the code does not need all the if else on language anymore. The value will be the expected text based on the language.

Instead of three line in the manifest like

Code:

Localization/HarvestMapData-en.lua
Localization/HarvestMapData-de.lua
Localization/HarvestMapData-fr.lua

It would be:

Code:

Localization/HarvestMapData-$(language).lua

Based on what the cVar("Language.2") hold, one of your three originally files will be loaded. This is how ZOS is doing the localization for the most part on strings.
Hope this help,

I understand that you want to store references from three different tables into the single table. If you use unique keys, it can be done using metatables. If you use just indexes (they are not unique), it will be much more complicated.

I don't know if it is exactly what you want, but I think it's worth of trying.

Lua Code:

Harvest.DataStore["en"]["alikr_base"] = {
   ["Aldunz"] = 3,
    .........
}
Harvest.DataStore["de"]["alikr_base"] = {
   ["Aldunz^N,in"] = 3,
    .........
}
Harvest.DataStore["fr"]["alikr_base"] = {
   ["Aldunz^M"] = 3,
    .........
}
 
Harvest.DataStore["alikr"]["alikr_base"] = {}
 
setmetatable(Harvest.DataStore["de"]["alikr_base"], { __index = Harvest.DataStore["fr"]["alikr_base"] })
setmetatable(Harvest.DataStore["en"]["alikr_base"], { __index = Harvest.DataStore["de"]["alikr_base"] })
setmetatable(Harvest.DataStore["alikr"]["alikr_base"], { __index = Harvest.DataStore["en"]["alikr_base"] })
