- - Lua 5.1 or 5.2? (https://www.wowinterface.com/forums/showthread.php?t=43205)

I know /run, /script and addons are not yet available for use in order to print _VERSION, but does anyone know if Blizzard said anything yet about updating to Lua 5.2?

Lua 5.2 has been released since December 2011, and maybe it would help a lot for addon authors to anticipate on it if Blizzard were to update it in MoP

/dump _VERSION prints out "Lua 5.1"

They were probably too far into MoP development to change it by the time it was released.

How much would 5.2 affect how blizzards own UI functions?

To mention what would be most impacted would be the SecureHandler system as it relies entirely on being able to create independent secure environments.

8.1 – Changes in the Language

The concept of environment changed. Only Lua functions have environments. To set the environment of a Lua function, use the variable _ENV or the function load.

C functions no longer have environments. Use an upvalue with a shared table if you need to keep shared state among several C functions. (You may use luaL_setfuncs to open a C library with all functions sharing a common upvalue.)

To manipulate the "environment" of a userdata (which is now called user value), use the new functions lua_getuservalue and lua_setuservalue.

8.2 – Changes in the Libraries

Functions setfenv and getfenv were removed, because of the changes in environments.

Mists of Pandaria will be running lua 5.1.

Currently there are no plans to move WoW's lua engine to 5.2.

Thanks for the confirmation, TSquared. :)

Not to be too offtopic but who is TSquared? I mean, other than knowing he's a blizzard employee.

Maybe Blizzard employees could get bold blue names, the way moderators get bold orange names?

They might want to stay somewhat anonymous, to avoid PM spam and whatnot.

TSquared already has private messages turned off to avoid such nonsense. ;)
