It was thus said that the Great Soni L. once stated:
In Lua you have 2 options:
1) Use function upvalues. (for local access)
2) Use the module table. (for shared access)
There's no such thing as a "registry" in Lua, it only exists in C (and
debug). I want to bring Lua on par with the C API and vice-versa.
I think I may have mentioned this before, but wrap Lua in Lua.
lua = require "lua"
L = lua.Lnewstate()
L:Lopenlibs()
L:getglobal("print")
L:push("this is a string")
L:call(1,0)
Short of that, what's in the C API that isn't available from Lua?
-spc (debug.getregistry() called. It's a bit miffed)
Well there are no functions to manipulate varargs as in
insert(pos, newarg, ...) -> return ...[1,pos], arg, ...[pos+1,-1]
remove(pos, ...) -> return ...[1,pos-1], ...[pos+1,-1]
replace(pos, arg, ...) -> return ...[1,pos-1], arg, ...[pos+1,-1]
sort([f ,]...) -> return sorted ...
reverse(...) -> return reversed ...
slice(i, j, ...) -> return ...[i, j]
etc
Either way, the original suggestion is/was to REMOVE the registry, not
to make it available from Lua. If Lua doesn't need a registry then
neither does C.
