The ref and ref-all functions bring back an address or list of addresses.
As cormullion wrote in the nL wikibook:
;-> ((0 2 14 528 6 1) (0 2 16 3186 6 1) (0 2 16 3226 6 1))
What would be the best way to get that data instead of the numerical addresses?
Essentially, once I find the address is (0 2 14 528 6 1), how best would I get what it actually is, not the address?
So how best to get (0 2 16 3186 6 1) data?
Thank you!
Sorry, I don't have time to answer from a concrete example that should first be created. But I think there are some interesting tracks in the wikibook, especially
Hi joejoe ,
the best way to get the data would be to map over the results and use implicit indexing.
So ref-all would give you a list of indices, probably the data you're looking for is one level up in this structure, then I would do:
(map (fn(x) (itunes-data (chop x))) (ref-all "Brian Eno" itunes-data))
Hi joejoe,
the "ref-all" and "ref" functions have a parameter to get data instead of indexes.
(ref-all 'a lst)
;-> ((0) (3 1) (3 3 0) (3 3 2) (4 1) (4 2 2))
(ref-all 'a lst = true)
;-> (a a a a a a)
But maybe I misunderstood the question.

Well seen ! I had completely forgotten this option.
Thanks, Cameyo.
Thanks very much for all the exemplars!
ref and map seem to carry things out quite well!
Much appreciated!
