Does Lua have a language standard?

I was wondering if somebody more experienced that I can tell me if Lua has a language standard. I am new to programming, and so I would assume that the reference manual is the language standard. If this is not true, are there other documents that are possibly equivalent t开发者_高级运维o a language standard? Thank you!

As stated clearly on the documentation web site:

The official definition of the Lua language is its reference manual, which describes the syntax and the semantics of Lua, the standard libraries, and the C API.
