I thought order didn't matter (unless otherwise stated) in core.logic. Is
there a way for me to infer which goals are like this? (by looking at the
code if not from docs)
I am trying to get this working:
(defn geto [c k v]
(matche [c]
([[]] (nilo k))
([[f . r]] (fresh [a] (firsto f a)
(conde [(== a k) (resto f v)]
[(geto r k v)])))))
(defn keyso [c k]
(matche [c]
([[]] (nilo k))
([[f . r]] (fresh [a b] (firsto f a)
(keyso r b)
(conso a b k)))))
(defn distinctkeyso [c]
(fresh [x]
(keyso c x)
(distincto x)))
(run 1 [q]
(fresh [x]
(geto x :tree false)
(== q true)
(geto x :tree q)
(distinctkeyso x)))
But it doesn't complete with that distinctkeyso. I tried to use maps but it
didn't work[1], so I decided to give lists a try. geto and keyso seem to
work fine.
