Re: Question about Lua Registry

[Cathal Garvey <cathalgarvey@...>]

Hey Geoff,
If I understand the question correctly, you want to see the keys/values
of all global variables in lua?

If so:
for key, val in pairs(_G) do
 print(key,val)
end

Obviously "val" will be rendered unsatisfyingly in cases of tables and
functions, but it'll give you an idea of what's there, at least. You
could do a check for tables and have a sub-loop to iterate through
those, if you liked..
