RE: Question about Lua Registry

Hi

Thanks for the replies
Nope it wasn't the globals that I wanted to see, it was the contents of the Lua Registry.

Rena's reply was exactly what I needed, nice and simple too, just a one liner. My Googling somehow managed to miss debug.getregistry ().

Thanks again
Geoff
