Re: ANN metrics-clojure 2.6.0 is released
Congratulations, I look forward to using this, upgrading to 3.1 is great and the features on the release notes (really nice to have clear, concise release notes) will make using it much better.

Re: Using cookies with clj-http.client
I don't see any problem with your code. Try to add :debug true to both of
those maps and look at the output. Ensure that for both URLs share exact
same hostname and protocol http/https. Look at the Set-Cookie header in
the POST response and ensure that the path matches the url in the GET.

usage of "and"
I am reading Clojure Applied, which I am enjoying. One code snippet is puzzling for me, can someone please explain why the authors used: (and (pos? cnt) instead of just (pos? cnt) ? Or to go further, (pos? (item @inventory)) The best I could think is that there used to be a check for two things: 1) that the entry was present in the map AND 2) the value for the entry was positive. But maybe there is some idiomatic use of "and" that I don't know about. The inventory atom is a map whose key is a keyword like :milk and the value is a count representing how many are left. (defn in-stock? "check if an item is in stock" [item] (let [cnt (item @inventory)] (and (pos? cnt Excerpt From: Ben Vandgrift, Alex Miller. “Clojure Applied P1.” iBooks. -- You received this message because you are subscribed to the Google Groups "Clojure" group.

every? expected behavior
Hi,
I am new to Clojure, so please forgive me if this does not make sense.
I was surprised to find out in the REPL that every? returns true if you
pass in an empty or nil collection.
user= (every? #(= 77 %) nil)
true
user= (every? #(= 77 %) '())
true
I looked at the source for every? and it made sense to me why this happens
given that every? is recursive and the termination condition is when coll
runs out of items to process.
Would it make more sense to define every? with a loop, or is the caller
expected to know better than to call it with nil?
Thanks,
--jeff
(defn every2?
Returns true if (pred x) is logical true for every x in coll, else
false.
{:tag Boolean
:added 1.0
:static true}
[pred coll]
(if (empty? coll)
false
(loop [c coll]
(cond
(nil? (seq c)) true
(pred (first c)) (recur (next c))
:else false

Re: every? expected behavior
Thanks to all for the nice explanations. I understand the reasoning.

Depends who is doing the expecting as to whether that behaviour is
correct. Formal logicians, mathematicians, computer scientists etc. would
respond sure, it is vacously true. For almost everybody else it feels
wrong but is then true when you think about it a bit.
I would suggest the question you are trying to ask is (and (not (empty?
nil)) (every? #(= 77 %) nil)).
For more info check out http://en.wikipedia.org/wiki/Vacuous_truth.
