Changes for Lua 5.2/5.3 compliance?

[bmatsuo]

Do you have any plan to make the changes necessary to be a compliant environment for newer (minor) versions of Lua? Of course Lua 5.3.2 being the latest version as of today. I don't really have a need for it. But I think it would be nice.

One thing I have noticed as a difference between the lua C programs is that the lua5.3 interactive interpreter (REPL) works much better than the lua5.1 repl. Surely more work has gone into it's presentation but, having implemented a simple REPL in 5.1 and seen the limitations, I wasn't sure if it was actually just easier to build a good REPL using the 5.3 C API.

From what I understand the Go API has some functions that correspond to functions added to the C API in Lua 5.2. But I'm not entirely sure about C API changes in Lua 5.3.

Is the existing Lua module API strictly compliant exactly with Lua 5.1? Or is in somewhere in-between versions?

I do not have any plans yet.
I did not see the Lua 5.3 codes, but I don't think Lua C API anything to do with the matter.

It is more important to make good use of rich console ui library like readline, prompt_toolkit, curses etc than Lua C API for improving the REPL environment. For example you can use chzyer/readline for that.

You may be correct about the lua5.3 repl. I was just wondering if maybe parser error codes had changed in a way that made error handling easier to work out. That is not too important to me though.

I suppose I am just more concerned about staying current rather than falling too far behind. And, also wondering how I can help out. I have been enjoying use of gopher-lua so far, and am heavily exploiting it for my latest project.

Would you rather work towards more a complete implementation of lua5.1?

On error handling, GopherLua has more structured API than C-Lua5.1 . #46 might be helpful for you.

Would you rather work towards more a complete implementation of lua5.1?

Lua 5.1 is considered as close to a “completed form”, and most widely used "specification" still in 2016(LuaJIT is upwards-compatible with Lua 5.1).

I have already implemented most of the Lua5.1 APIs, so I do not take an active interest in it.

Ok. I understand. Thanks. Honestly I don't know what "most lua programmers" do most of the time.

Thanks for the great package :)
