Deobfuscate Lua scripts?

Question

Does anyone know how I can deobfuscate a lua script that uses xfuscator to hide it? The obfuscation looks like this. If anyone could give me a point into the right direction on

Answer 1

See that long table? That's the real code. It's a pattern you see quite often with obfuscators. Other than that, keep in mind that _, __0 and such are all valid Lua identifiers, to you can have variables named like that.

_ is a function that turns a number into a character; __0 is a table that contains some standard functions. There's nothing special going on beyond that. If you see a __0[1]("Hello"), that'd be the same as print("Hello"); it just looks weird, because they put print into the __0 table at index 1.

Ultimately, the obfuscator just makes use of Lua features that people often don't understand well enough to understand what's going on. If you know the language though, it's all just smoke and mirrors.
