Methods

ToLuaStack a => ToHaskellFunction (Lua a)

Methods

toHsFun :: StackIndex -> Lua a -> Lua NumResults

luaState :: Lua LuaState

Get the lua state of this lua computation.

runLuaWith :: LuaState -> Lua a -> IO a

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.

liftLua :: (LuaState -> IO a) -> Lua a

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

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

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