I'm probably just especially dense today, but perhaps someone can give me a
poke in the right direction.
I'm trying to wrap my head around transducers.
(1) For debugging purposes I'd like to be able to consume the values on a
channel and put them in a collection to be printed.
I'm doing this at the REPL:
(async/<!! (async/into [] channel))
This seems needlessly clunky. Is this really the best way to accomplish
this?
(2) async/map> is deprecated, what's the alternative, exactly?
(let [ch (async/to-chan [1 2 3])]
(async/map> inc ch))
AFAICT this would produce a channel, which when consumed would yield the
values 2 3 4, correct?
Now I suppose if I didn't already have the channel ch, I could create one
with an associated transformation function, and then stuff the values 1 2 3
into it somehow, right?
(let [ch (async/chan nil (map inc))]
(async/onto-chan ch [1 2 3])
ch)
;; returns a channel yielding items 2, 3, 4
But, I'm not clear at all how I can apply the operation (inc) to the all
values yielded by a channel I already have in my hand.
Any help would be appreciated. I feel like I'm missing some critical bit of
insight and that async and transducers might just fall into place for me if
I could only find out what that bit is.
