Lua 5.2 & SWIG compatibility problem

[Jeff Smith <spammealot1@...>]

Hi
 
Just a heads up as I havent seen any previous mention of this problem on the mailing list before.
 
I started updating my project to switch from 5.1 to 5.2 but hit a pretty awkward showstopper problem. I use SWIG extensively to generate auto bindings.
 
The SWIG auto generated code uses LUA_GLOBALSINDEX which no longer exists in 5.2.
 
I found a recent Swig user post discussing the problem http://old.nabble.com/Lua-5.2-alpha-compatibility-td30299686.html
 
It would be good if someone from the Lua team could confirm the best fix for this issue is to replace  the LUA_GLOBALS_INDEX line with

 
/* push the global table onto the stack */
lua_getglobal(L,"_G")
 
by "best" I mean a fix that works for both 5.1  & 5.2.  Or alternatively, is there an easy fix to the Lua source to save having to patch the SWIG source code ?
 
 
There is a second small compatibility issue with luaL_Reg &  luaL_reg,  but that one is trivial to work around, and doesnt need a patch to the SWIG source, so no big deal.
 
Its unfortunate that 5.2 breaks SWIG and needs a patch to the SWIG source to fix, especially as there seems to be no SWIG - Lua maintainer at present.
