Hello,
Hi!
----
local mt =
{ __index = {},
}
local mt2 =
{ __index =
function(ttt, k) print("mt2", ttt, k) end -- [1]
}
setmetatable(mt.__index, mt2)
local t = setmetatable({}, mt)
----
So, question: how to (anyhow) pass the table 't' to the function [1] so
that be able to access 't' members?
I can think of two ways: 1.) Forget about `mt` and make `mt2` the metatable of `t`.2.) Make function [1] a closure referencing `t` (but you will need to duplicate `mt`, `mt.__index`, `mt2`, and `mt2.__index` for every new table like `t`). To give you more useful answers, I need to know what you are trying to do ...
Best regards, Lukas
