How can I substitute one dictionary's missing contents with content from another dictionary?





.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

So, I'm doing translations for a game, and I have different dictionaries. If a translation doesn't exist in one language, I want to set it to the English translation. Every method I've tried to combine the dictionaries has ended up incredibly inefficient.



Here are some cut down examples



local translation-sr = {
Buttons = {
Confirm = "Потврди";
Submit = "Унеси";
};
Countries = {
Bloxell = "Блоксел";
USA = "Сједињене Америчке Државе";
};
Firearms = {
Manufacturers = {
GenMot = "Џенерални Мотори";
Intratec = "Интратек";
TF = "ТФ Оружје";
};
};
};

local translation-en = {
Buttons = {
Confirm = "Confirm";
Purchase = "Purchase";
Submit = "Submit";
};
Countries = {
Bloxell = "Bloxell";
USA = "United States";
};
Firearms = {
Manufacturers = {
GenMot = "General Motors";
Intratec = "Intratec ";
TF = "TF Armaments";
};
};
Languages = {
Belarusian = "Belarusian";
English = "English";
French = "French";
German = "German";
Italian = "Italian";
Russian = "Russian";
Serbian = "Serbian";
Spanish = "Spanish";
};
};

I guess you want to do something like this



setmetatable(translation_sr.Buttons,{__index=translation_en.Buttons})


for all leaf subtables. You can do this by hand if there are only a few subtables.

    I believe you should use a metatable to accomplish what you need.



    I assume that you will always index by the English default word. With that true you can do the following.



    local function default(t,k)
    return k
    end

    local translation_sr = {
    Button = setmetatable({
    Confirm = "Потврди",
    Submit = "Унеси",
    },
    { __index = default }),

    Countries = setmetatable({
    ["Bloxell"] = "Блоксел",
    ["United States"]= "Сједињене Америчке Државе",
    },
    { __index = default }),

    Firearms = {
    Manufacturers = setmetatable({
    ["General Motors"] = "Џенерални Мотори",
    ["Intratec"] = "Интратек",
    ["TF Armaments"] = "ТФ Оружје",
    },
    { __index = default }),
    },
    }


    This function simply returns your key that was not present in the table.



    local function default(t,k)
    return k
    end


    With this key being assumed to be the English word you would use as the default the returned value for "Purchase" you would get "Purchase" back from the translation_sr. This method requires no translation_en table

                  Countries = setmetatable({
                  ["Bloxell"] = "Блоксел",
                  ["United States"]= "Сједињене Америчке Државе",
                  },
                  { __index = default }),

                  Firearms = {
                  Manufacturers = setmetatable({
                  ["General Motors"] = "Џенерални Мотори",
                  ["Intratec"] = "Интратек",
                  ["TF Armaments"] = "ТФ Оружје",
                  },
                  { __index = default }),
                  },
                  }


                  This function simply returns your key that was not present in the table.



                  local function default(t,k)
                  return k
                  end


                  With this key being assumed to be the English word you would use as the default the returned value for "Purchase" you would get "Purchase" back from the translation_sr. This method requires no translation_en table
