Tide · API

tide.load

tide.load loads the reflexes Tide runs from then on. It parses each reflex, validates the set as a whole and returns a report; a host calls it again to change what runs. blind lists each reflex whose effect handler declares no writes, so Tide cannot determine which reflexes it may trigger.
