Documentation

getglobal' :: String -> Lua ()

Like getglobal, but knows about packages and nested tables. E.g.

getglobal' "math.sin"

will return the function sin in package math.

setglobal' :: String -> Lua ()

Like setglobal, but knows about packages and nested tables. E.g.

pushstring "0.9.4"
setglobal' "mypackage.version"

All tables and fields, except for the last field, must exist.

runLua :: Lua a -> IO a

Run lua computation using the default HsLua state as starting point. Raised exceptions are passed through; error handling is the responsibility of the caller.

runLuaEither :: Lua a -> IO (Either LuaException a)

Run the given Lua computation; exceptions raised in haskell code are caught, but other exceptions (user exceptions raised in haskell, unchecked type errors, etc.) are passed through.
