Starting Lua

[RLake@...]

> is there any way to make a Lua variable reference another variable?

A Lua global is actually a key in the global environment table. So if _G is
the global environment table (which it is if you haven't changed it with
setfenv and you are using the standalone Lua interpreter) then

  a

is the same as

  _G.a

is the same as

  _G["a"]


Hope that helps
