Hi,

I'd like to ask a couple of questions.

1) Is fine to upvalue a function using it's same name ?

Something like:

local string.format = string.format

I usually wrote something like:

local string_format = string.format

It obviusly works but in this way I dont have the syntax color of the editor :/
Does it have some dark side effects ?

2) Another question.

Until now I usually initialize (wrongly) my vars in this way.

-- beginning
local ADDON = ...
 
-- defaults 
 
MYADDON_CFG = {
    KEY1 = true,
    KEY2 = "var2",
    KEY3 = 3,
}

Now I have understood better that the vars are overwritten during ADDON_LOADED event so I can write in this way:

frame:SetScript("OnEvent", function(self, event, arg1, ...)
 
    if event == "ADDON_LOADED" and arg1 == ADDON then 
        -- Some defaults I dont want to be nil
        if MYADDON_CFG["KEY1"] == nil then MYADDON_CFG["KEY1"] = true end
        if MYADDON_CFG["KEY2"] == nil then MYADDON_CFG["KEY2"] = "var2" end
        if MYADDON_CFG["KEY3"] == nil then MYADDON_CFG["KEY3"] = 3 end
        frame:UnregisterEvent("ADDON_LOADED")
    end

What I want to ask ... Is there a better way to write values in an array if they are null ? Or the

if then end

for every key is a good enough solution ?

Thanks so much to everyone and patience.
