Get the lua state of this lua computation.

Run lua computation with custom lua state. Errors are left unhandled, the caller of this function is responsible to catch lua errors.

liftIO :: MonadIO m => forall a. IO a -> m a #

Lift a computation from the IO monad.

Turn a function of typ LuaState -> IO a into a monadic lua operation.

liftLua1 :: (LuaState -> a -> IO b) -> a -> Lua b Source #

Turn a function of typ LuaState -> a -> IO b into a monadic lua operation.
