Lua - Get directory zzz.lua

Leju

I am creating an addon and I'm stuck on one thing, when I use the following line in the Lua

• local dir = debug.getinfo(1).source

it returns me the following result

• @game:/EsoUI/lang/br_pregame.lua

and what I need to know and exactly the way it is @game: by chance would have the game function something that could help me?
