Re: Question on get/setmetatable()

I've written my own, which I can use in the console using a simple require() to load the function in the console, mw.logObject(t) is not practical at all for its intended use. It still has indentation where line breaks are inserted (not after each key/value pair, it reduced the presentation of keys (when they are numbers or strings not containing spaces, commas, or '=', and escaping the quotes as needed. It also supports the optional numbering of tables/functions (if there's a cycle in a key or value, it just shows a "...", using a much simpler approach to avoid infinite loops that does not need any marking with a store proportional to the number of tables or functions encountered but only proportional to the maximum depth, so it works in the memory constraints of 55MB enforced by Scribunto's sandboxing of Lua and is useful for debugging scripts without breaking them with memory exhaustion errors)

I have no clue of what point you are trying to make here, or what you
are replying to.

Mine does not do it.

Seems you do not like that mw thingie. Why don't you just find another
one that better suits your tastes? Or write your own as I did?
