Lua 5.2 released, is there a plan to use it?

Hi Robin,
I checked your repo and as long as you add the proxy script.h to the engine and change all the files that use #include <lua.h> to #include "script.h"
I guess you'll be fine, you have a sandbox.lua that I think runs in Lua 5.2, but I'm not sure
I know nothing about sandboxed environments, just this morning I saw something like this in the lua list, but it was not in my radar

Are you compiling Lua in compatibility mode? Does luasocket compile cleanly with it?

Code: Select all

#define LUA_GLOBALSINDEX    LUA_RIDX_GLOBALS

That works different now. LUA_GLOBALSINDEX is a pseudo-index for the stack. LUA_RIDX_GLOBALS is a index for the registry.
Only the physics module uses the code with this macro.

Ah! I forgot, I had defined the LUA_COMPAT_ALL at project level.
Yes luasocket compiles cleanly with my redefinitions, I don't know how to test it though...

LUA_GLOBALSINDEX I changed it using some advice I found online, I totally ignore if it's safe or not until more test.

Oh, the damage is not as bad as I thought. It doesn't use setfenv() after all, which I thought it did.

I had put a compiled version on my fork:

https://bitbucket.org/ex/love

I'm only using the VS2008 solution, if you want to compile it I think all the windows dependencies are there.

PS: Does somebody know how to set my icon avatar correctly in Bitbucket? I have my email set but maybe I'm missing something.

You set your avatar on gravatar, iirc.

Yes my avatar appears in my account page, but whenever I commit I get a ex? user without icon, I found something like that in the forum but I think I'm forgetting to set my email in some place... I just starting to use TortoiseHG and can't find a place where to set that.

Well, I'm the linux maintainer, and I like to overstate the amount of people running linux here. That said, even though it compiles cleanly, there will be few repos that actually have 5.2.

In debian experimental, liblua5.2 is currently at version rc5. It'll be sometime before we even see it make it to sid, and even longer before it gets to wheezy where Ubuntu will pick it up. I'd say that _maybe_ we would see it in ubuntu 13.10. So, there's no rush to get it in.

That makes me a sad panda.

The Linux world does not only consist of Debian and Ubuntu. For instance distros like ArchLinux always like to have the newest stuff. And Lua5.2 has some great improvements in it, so that it is worthwhile to support it in the closer future.

Didn't knew about GOTO introduction in LUA. Although not really needed I think it brings extra flexibility with labelled jump control. It's welcomed if appear in LOVE. Who thinks that is "evil" just don't use it, others should control their code as they want.
