00:03	mdeboard	,(fn [s] (let [sep #"," foo (clojure.string/split s sep)] (if (= (str (last s)) (str sep)) true false)))
00:03	clojurebot	#<sandbox$eval73$fn__74 sandbox$eval73$fn__74@15c2817>
00:03	mdeboard	Whoops, well yeah that
00:03	mdeboard	,((fn [s] (let [sep #"," foo (clojure.string/split s sep)]
00:03	mdeboard	(if (= (str (last s)) (str sep)) true false))) "a,b,c,d,")
00:03	clojurebot	#<RuntimeException java.lang.RuntimeException: EOF while reading>
00:04	mdeboard	,((fn [s] (let [sep #"," foo (clojure.string/split s sep)] (if (= (str (last s)) (str sep)) true false))) "a,b,c,d,")
00:04	clojurebot	true
00:04	mdeboard	,((fn [s] (let [sep #"," foo (clojure.string/split s sep)] (if (= (str (last s)) (str sep)) true false))) "a,b,c,d")
00:04	clojurebot	false
00:04	mdeboard	kelseygi: ^ ?
00:04	kelseygi	yeah, that’s where i was going—check the last char, treat the array differently in each one
00:05	kelseygi	i guess i was secretly hoping for something like a split-with on string with regex?
00:05	andyf	,(clojure.string/split "a,b,c,d" #"," -1)
00:05	clojurebot	["a" "b" "c" "d"]
00:05	andyf	,(clojure.string/split "a,b,c,d," #"," -1)
00:05	clojurebot	["a" "b" "c" "d" ""]
00:05	andyf	kelseygi: ^^^
00:06	mdeboard	noice
00:06	kelseygi	ooooh!
00:06	mdeboard	stil have to treat the array differently :P
00:06	kelseygi	i totally missed that in the clojuredocs example, thank you!
00:07	kelseygi	that works for this particular case, the thing i was going to do if it doesn’t end in the separator was store an empty string
00:08	dbasch	that should be in the doc string, because it’s not obvious behavior for the limit parameter
00:08	mdeboard	Now, what about comparing vectors? like how would I "diff" [1 1 3 5] and [1 1 2 3 4 5 5], such that it would return [2 4 5]
00:09	kelseygi	dbasch: much agreed
00:09	mdeboard	there are dupes so sets wouldn't work
00:10	andyf	dbasch: You can create a ticket requesting such a change. It may or may not be accepted. Not easy to tell until one tries.
00:10	andyf	doc strings tend to be terse
00:10	andyf	by choice
00:10	mdeboard	far too terse in many cases
00:11	dbasch	andyf: true, but they do try to document the expected behavior of a function with expected parameters
00:11	andyf	One can make their own doc strings that expand on the originals, e.g. https://github.com/jafingerhut/thalia
00:12	andyf	That project only scratches the surface, and I haven't added to it in a while, but if people are interested in longer doc strings and have the time to write them, send a pull request.
00:12	johnwalker	thanks for lein 2.4.2
00:12	dbasch	e.g.
00:12	dbasch	,(reduce 1 1 [])
00:12	clojurebot	1
00:12	dbasch	^^ that works according to the doc string of reduce
00:13	johnwalker	,(reduce 'foobar 1 [])
00:13	clojurebot	1
00:13	andyf	mdeboard: If you want to write 600 expanded doc strings, or even 10, go for it. I don't mean that sarcastically -- it only takes time.
00:13	johnwalker	hahaha
00:13	johnwalker	thats cute
00:14	mdeboard	andyf: I mean, it's not a philosophical point... many doc strings are close to useless as documentation, i.e. helping people understand what a function does.
00:14	andyf	one can complain, or one can do something useful about it
00:15	mdeboard	I mean, I literally can't do something useful about it because I don't know what the function does because their documentation doesn't explain it well
00:16	andyf	there is the source code, and docs on the Java API's
00:16	andyf	I am not demanding that you do something -- I am pointing out an alternative to complaining. That's all.
00:16	mdeboard	eyeroll
00:16	mdeboard	at the passive aggressiveness
00:17	andyf	There is no aggressiveness in my mind at all.
00:18	hellofunk	Anyone know how to route an abitrary URI like /whatever to show the contents of a specific HTML file? route/files seems to require the URI is the HTML file
00:18	hellofunk	Using Compojure, of course
00:18	johnwalker	did you see what hyPiRion did with deliver dbasch?
00:18	brehaut	hellofunk: just make a route and return that specific html file
00:19	brehaut	files are a vald response :body
00:19	dbasch	johnwalker: no
00:19	hellofunk	brehaut: when you say "return" it, how exactly?
00:19	johnwalker	,(map deliver [inc dec] [10 11])
00:19	clojurebot	(11 10)
00:20	hellofunk	brehaut: you mean [:body "something.html"] ?
00:20	umpa	,(defmacro forever [& body]`(while true ~@body))
00:20	clojurebot	#'sandbox/forever
00:20	johnwalker	he also did a good one with with clojure.string/replace
00:20	brehaut	hellofunk: return {:body (clojure.java.io/file path-to-filename) ...}
00:21	brehaut	hellofunk: you need to go learn about ring right away
00:21	brehaut	hellofunk: https://github.com/ring-clojure/ring/
00:21	dbasch	johnwalker: that’s a bit unexpected :)
00:22	hellofunk	brehaut ah doing it at the ring layer, not the compojure layer
00:22	hellofunk	brehaut or rather the hiccup layer
00:22	brehaut	hellofunk: compojure is just a small layer on top of ring, you cant use compojure without also using ring
00:22	johnwalker	his replace was better, but it was something like this
00:22	johnwalker	,(clojure.string/replace "$1000$5000" #"\d{4}" (fn [s] (apply str (reverse s))))
00:22	clojurebot	"$0001$0005"
00:23	johnwalker	well, he actually did a parseint and exchanged those for unicode characters
00:23	johnwalker	but the idea is that you can pass functions to clojure.string/replace when the second arg is a regex
00:23	johnwalker	it doesn't work for strings, which is slightly irregular
00:24	brehaut	hellofunk: hiccup is just an html rendering layer
00:31	hellofunk	whenever I change my compojure routes function, i notice I must stop the webserver, compile the entire source file, then start the server again (connecting localhost). does this seem right?
00:31	johnwalker	have you tried using a var
00:31	johnwalker	for your routes?
00:31	johnwalker	with #'
00:32	hellofunk	looks like it is a var: (jetty/run-jetty (wrap-app #'app) {:port port :join? false}
00:33	hellofunk	ah, perhaps because my #'app refers to a def that in turn then refers to my routes, since #' is wrapping the routes inside cemerick's friend
00:34	johnwalker	i don't actually know if thats related
00:34	johnwalker	seems like it should work
00:35	hellofunk	johnwalker: good catch. I had one reference as a var, but what it referred to then did not reference my routes as var. changed that, workign nicely.
00:35	hellofunk	the Friend example doesn't use vars so I hadn't either.
00:35	johnwalker	oh, gotcha
00:35	johnwalker	glad i could help
00:39	hellofunk	johnwalker so am i!
00:40	johnwalker	:)
00:57	hellofunk	do i understand correctly that clojure.java.io/resource will look directly and implicitly in the leinengen resources/ directory?
01:00	amalloy	today's reminder of little-used clojure features: an alternate to the standard single-line comment character ";" is available in #!, in case you hate semicolons
01:01	hellofunk	amalloy curious are ; and #! both reader-level comment symbols?
01:01	amalloy	yes
01:01	amalloy	hellofunk: it seems completely bizarre and pointless - who would use #! instead of a semicolon? but then you remember that that's a shebang
01:01	hellofunk	as opposed to (comment ...) which is actually compiled
01:01	hellofunk	a shemale, what?
01:01	hellofunk	in clojure??
01:02	lazybot	hellofunk: Uh, no. Why would you even ask?
01:02	hellofunk	oh, misread...
01:02	amalloy	good answer, lazybot
01:02	amalloy	as always
01:02	hellofunk	indeed that was impressive. what triggered that response? the double question mark?
01:03	hellofunk	questions ending in clojure??
01:03	hellofunk	guess not
01:03	lazybot	hellofunk: Uh, no. Why would you even ask?
01:03	hellofunk	lazybot likes shemales?
01:03	hellofunk	guess not
01:03	hellofunk	you like this, what?
01:05	TEttinger	??
01:05	lazybot	TEttinger: What are you, crazy? Of course not!
01:05	clojurebot	? is suddenly
01:05	ecfuser59999	Does anyone know if the limit of 4 primitive arguments will be removed ?
01:06	amalloy	i wouldn't bet on it, ecfuser59999
01:06	amalloy	it's pretty rare to need more than four distinct primitive args, and if you really do you can shove them into an array
01:07	ecfuser59999	I do math modelling and could easily use 10 or primitive arguments. Yes I could use an array but not a very nice way to pass parameters!
01:09	ecfuser59999	thanks anyways
01:25	mdeboard	How would I "diff" [1 1 3 5] and [1 1 2 3 4 5 5], such that it would return [2 4 5]
01:25	mdeboard	i feel like i'm missing something
01:39	amalloy	mdeboard: well, diff is a vaguely-defined problem. if it's guaranteed that all elements of the first list are present in the second, in the same order (or if those are the only answers you care about), then it's not too hard
01:40	mdeboard	amalloy: I think I got a solution with `frequencies`
01:40	amalloy	that's fine too, if you don't care about order
01:42	amalloy	if you wanted to diff them in order, by which i basically mean "which elements from b would you have to remove in order to get a", you can do something like https://www.refheap.com/86669
01:43	amalloy	behavior is undefined if there's no way to remove elements from b and wind up with a
01:53	amalloy	mdeboard: ^
02:00	mdeboard	amalloy: interesting, thanks
02:14	mdeboard	I mean the "funny" part of this purely functional approach is that I'm managing exactly as much state as I was before
02:27	hellofunk	mdeboard you are using atoms, refs a lot?
02:38	ayia	Hi guys. I need a collection in clojure with specific rule for adding new elements. What is the best way to do this in clojure? I tried to ask google, but did not find much... It was even hard to build a proper query because I don't know the correct direction to go...
02:38	hellofunk	ayia what kind of rule?
02:40	pyrtsa	amalloy: Diff in general is a vaguely-defined problem but what mdeboard seemed to be talking about and what you came up with a good answer for in https://www.refheap.com/86669 is the well-defined problem of difference of sorted sequences, or essentially, bags.
02:40	ayia	hellofunk: My collection should be (most a probably a set) a collection of "path" vectors like [1 0 0 0], [1 0 1 0]... The rule should be: the new vector is "ok" to be conj-ed if it has at least one "peek/node/element" with bigger number at correspondent location... hm... hard to explain... will think more now:)
02:43	ayia	E.g. if I have [[1 0 2 0][2 0 1 0]] then I can't conj-ed [1 0 1 0], because no one from its peeks is "higher" than any other peek in correspondent place at available "paths"
02:44	ayia	OK paths are: [3 0 1 0], [1 0 3 0], [1 1 2 0], [2 0 1 1], [2 1 1 0], etc...
02:47	mdeboard	i'm doing this wrong, right? https://github.com/mattdeboard/ticket-to-ride/blob/functional-refactor/src/ttr/board.clj#L326-L347 All the swap! calls seems weird as hell to me
02:49	mdeboard	I guess I'm just not thinking with recursion hard enough
03:04	amalloy	yes, mdeboard, that's madness. all those swap! calls are just describing one pure function that acts on state, composed of five shorter ones
03:05	amalloy	(swap! state (fn [state] (-> state (update-in [:players pname :routes :claimed] concat route) ...)))
03:07	amalloy	really all of claim! can probably be a single swap! call, which takes in an old state and returns a new state
03:07	amalloy	once you've done that, it becomes clear that you can drop the swap! and the atom from claim! entirely, and just call the function claim instead. then you can write (swap! state claim pname route)
03:08	amalloy	does that make sense, mdeboard?
03:29	dhkl	When creating a map using the map literal {} in 1.6.0, (class {:a 1 :b 2}) says that it is a PersistentArrayMap, but when evaluating the form {:a 1 :b 2}, the insertion order is not perserved like an array-map should. What causes the inconsistency?
03:36	amalloy	map ordering should be regarded as entirely coincidental, unless you are specifically using a sorted-map
03:48	dhkl	Thanks amalloy
04:31	yocapybara	wonder if anyone can help a noob - I've got a sequence (2 4 6 8), and I've got a sequence of maps ( {a: 1} {a: 5 b: 2} {a: 4} {a: 5}) - I'm trying to get a sequence of maps but with items from that sequence in it as values, like ( {a: 1 new:2} {a: 5 b: 2 new: 4} {a: 4 new: 6} {a: 5 new: 8} ). I've been thinking of something like mapping assoc-in over the sequence of maps but my brain isn't working.
04:35	amalloy	yocapybara: you want to map a function over the two sequences at once: (map (fn [a b] (assoc b :new a)) as bs)
04:36	ddellacosta	,(map #(assoc %1 :new %2) '({:a 1} {:a 5} {:a 4} {:a 5}) '(2 4 6 8))
04:36	clojurebot	eval service is offline
04:36	ddellacosta	d'oh
04:36	ddellacosta	yocapybara: anyways, that's basically the same as what amalloy just said ^
04:37	amalloy	ddellacosta: lazybot's eval service is never offline, for what it's worth. as long as lazybot himself isn't offline, anyway
04:37	ddellacosta	amalloy: oh, didn't realize that, thanks
04:37	ddellacosta	&(map #(assoc %1 :new %2) '({:a 1} {:a 5} {:a 4} {:a 5}) '(2 4 6 8))
04:37	lazybot	⇒ ({:new 2, :a 1} {:new 4, :a 5} {:new 6, :a 4} {:new 8, :a 5})
04:37	yocapybara	amalloy, ddellacosta: thanks guys - that's where I started off but I couldn't quite figure it out. Hopefully it'll get easier as I get more used to thinking in clojure
04:38	ddellacosta	yocapybara: np, speaking from experience it does seem to. :-)
04:39	yocapybara	ddellacosta: :)
04:41	ayia	I have added my question at https://stackoverflow.com/questions/24239606/how-to-validate-filter-new-elements-to-be-conj-added-to-collection-in-clojure. I will appreciate any help... Thanks...
04:45	clgv	ayia: if [1 0 1 0] and [0 0 1 0] was acceptable, you are looking for incomparable/non-dominating in the sense of pareto-optimality
04:46	clgv	ayia: btw why is [2 0 1 1] [2 1 1 0] valid when the above example is not?
04:46	ddellacosta	ayia: here's one solution I think
04:46	ddellacosta	&(defn add-peak [peak peaks] (if (>= (reduce + peak) (reduce + (first peaks))) (conj peaks peak) peaks))
04:46	lazybot	java.lang.SecurityException: You tripped the alarm! def is bad!
04:47	clgv	ayia: or is insertion order important? such that [0 0 1 0], [1 0 1 0] would be valid
04:47	ddellacosta	&(add-peak [1 0 1 0] #{[1 0 2 0][2 0 1 0]})
04:47	lazybot	java.lang.RuntimeException: Unable to resolve symbol: add-peak in this context
04:47	ddellacosta	whoops
04:47	clgv	deevus: you want clojurebot since he allows `def`
04:47	ddellacosta	ayia: anyways, try that ^
04:47	ddellacosta	clgv: clojurebot is offline now I believe
04:48	clgv	still? is he still rolling dice?
04:48	ddellacosta	,(defn add-peak [peak peaks] (if (>= (reduce + peak) (reduce + (first peaks))) (conj peaks peak) peaks))
04:48	clojurebot	eval service is offline
04:48	ddellacosta	d'oh
04:49	ddellacosta	ayia: my solution doesn't have particularly good efficiency but it works according to your constraints I believe
04:49	ddellacosta	ayia: oh actually, I guess it's not bad
04:49	ddellacosta	ayia: but it's not right...d'oh
04:50	clgv	ddellacosta: did you understand clearly what he wants?
04:50	ayia	clgv: since we have #{[1 0 2 0][2 0 1 0]}, then [1 0 1 0] is not acceptable because its 0th element is not "higher" than 0th element of both already existed in a set...
04:50	ddellacosta	clgv: I thought I did
04:50	ddellacosta	clgv: but I realized my solution was making the wrong assumption
04:51	clgv	ayia: to validate a single state strictly speaking a set would be wrong since you are interested in a time-order?
04:51	ayia	[2 0 1 1] is acceptable because its 3rd element is higher than 3rd element of both vectors in a set
04:51	clgv	ayia: how can that be ok? [1 0 3 0] [1 1 2 0]
04:51	ddellacosta	yeah, the only thing I'm coming up with is O(n^2) I think
04:51	clgv	it shrank on index 2
04:53	ayia	clgv: i did not mention "time"... because I though it was a separate problem. And solution for it, I know:) I think so at least:)
04:53	ddellacosta	ayia: so, would this work? (defn add-peak [peak peaks] (if (>= (reduce + peak) (apply max (map #(reduce + %) peaks))) (conj peaks peak) peaks))
04:54	ddellacosta	that's assuming no ordering though
04:54	clgv	ayia: can you formulate mathmatically what a new vector must fulfill with respect to a vector of the set to be added?
04:54	ayia	actually my collection entries will be like: #{ {:peeks [1 0 2 0] :time 2000} {:peeks [2 0 1 0] :time 1000} }. And I want to sort it by :time
04:55	clgv	ayia: so peeks can vanish but somtimes they are not allowed to?
04:57	clgv	ayia: well if it some easy predicate that only one position must be bigger just use every?+some
04:58	ayia	hm... first of all... don't think much of this case like real emulation... The task I am solving is "mathematical"... It has no any sens about mountains:) I decided to use "mountains" terms just because it was easier for me to explain...
04:59	clgv	well if it is math better describe it with text+formulas next time ;)
04:59	ayia	So... My case... Is the case of some "virtual" mountains ridges... That can appear on the earth (let it be a sorted set) but only if they a "cooler" at least in something that any other ridge on earh
04:59	ayia	The "coolness" is the hight of at least some peak
05:00	ayia	clgv: sorry:) next time i will try with formulas... I have no formulas though....
05:01	ayia	I have only description:) in words:) but in terms of "vectors and their elements" not ridges...
05:03	ddellacosta	ayia: I'm not sure what your goals are with this; if you want a solution in clojure then I would use something like the function I posted above and sort the set after the fact.
05:03	clgv	ayia: yeah, if you want the one vector position must be higher you can just check that by using `every?` on the set and `some` on the positions to compare the given element with one of the set elements
05:14	ayia	clgv: yeah... that seems to be straightforward solution... I just thought may be there is any more "elegant" solution... In this task I can do like this... But if for example I will use often different implementations of "sets" with custom "element uniqueness definition"... Is there a way to implement this in clojure in a convenient way?
05:15	ayia	"like any way to add rule of uniqueness to the set"... like you add a custom "comparator" to the sorted-set
05:17	clgv	ayia: no your actually not changing the uniqueness property of the set. you just write a custom conj-like function that decides whether to add or not a given element
05:18	clgv	ayia: if you want something generic it would just boil down to (defn cond-conj [s pred x] (cond-> s pred (conj x)))
05:18	clgv	oops
05:18	ddellacosta	is it something I said
05:19	clgv	ayia: I meant it like that (defn cond-conj [s pred x] (cond-> s (pred s x) (conj x))) where pred is the "uniqueness" predicate in your words
05:20	ayia	clgv: I see... Good note! Thanks!
05:21	rurumate	what's a quick way to do a wget style download in clojure?
05:21	clgv	rurumate: `slurp` ?
05:21	rurumate	oh right, slurp takes an url I forgot thanks
05:22	clgv	rurumate: (slurp "http://www.google.de") ^^
05:22	rurumate	but that will load the thing to memory right? I want it written to a file
05:22	rurumate	because it's 28 mb binary
05:22	clgv	so?
05:22	clojurebot	so is (add-to-list 'erc-keywords '("\\bso\\b" erc-default-face))
05:22	clgv	I'd have believed you if it was 5GB ;)
05:23	rurumate	no, we have not achieved that level of bloat yet. but we're working on it
05:23	clgv	rurumate: well the solution gets more complex when you require directly writing it to a file
05:24	clgv	you got to setup an inputstream for the URL and an outputstream for the file and there should by clojure.java.io/copy*
05:25	rurumate	oh, so I so (with-open [in (bla) out (bla)] (copy in out))?
05:26	rurumate	why the starred version of copy though?
05:27	clgv	rurumate: didnt know if it was called copy-stream maybe ;)
05:27	rurumate	I'll try and post result when it's done
05:32	fenrock	clojure.java.io/copy "does not close any streams except those it opens itself (on a File)", which i take to meaning you only need the with-open if you're using streams, otherwise you should be able to do (io/copy (io/file src) (io/file dst)) and all streams will be closed for you, and it's buffered
05:32	rurumate	ok so the input will be a stream, but not the output
05:33	fenrock	but i think you mentioned a stream, so former will probably be right
05:33	fenrock	yarp
05:56	rurumate	seems workey: https://www.refheap.com/86675
05:57	clgv	rurumate: looks good
05:57	clgv	rurumate:
05:57	clgv	rurumate: you probably can omit the `file` expression since it coercing anyway, a string or url would be coerced as well
05:58	rurumate	clgv: would anything but a file make sense here?
05:58	rurumate	what if dest is url?
05:59	rurumate	if we know it would fail, I think it's better to coerce explicitly
06:30	clgv	rurumate: well coercing url to a file wont change that it might file if it is not writable ;)
06:30	clgv	*fail
06:54	silasdavis	is there a nice way to
06:55	silasdavis	,((juxt (partial map first) (partial map second)) [[1 2][3 4][5 6]])
06:55	clojurebot	[(1 3 5) (2 4 6)]
06:55	silasdavis	nicer*
06:56	philandstuff	,(map vector [1 2] [3 4] [5 6])
06:56	clojurebot	([1 3 5] [2 4 6])
06:56	bob2	darn, too slow
06:56	silasdavis	great
06:57	silasdavis	,(apply map vector [[1 2][3 4][5 6]])
06:57	clojurebot	([1 3 5] [2 4 6])
06:57	philandstuff	also works for more than two entries in the inputs
06:58	pyrtsa	,(apply mapv vector [[1 2][3 4][5 6]]) ;; if you want to keep the structure
06:58	clojurebot	[[1 3 5] [2 4 6]]
06:58	silasdavis	yep, I forget map works that way
06:58	philandstuff	,(map vector [1 2 3] [4 5 6] [7 8 9])
06:58	clojurebot	([1 4 7] [2 5 8] [3 6 9])
06:58	silasdavis	pyrtsa, also handy
07:00	clgv	you can call that `transpose` ;)
07:00	pyrtsa	,(def transpose (partial mapv vector))
07:00	clojurebot	#'sandbox/transpose
07:00	pyrtsa	,(transpose [[1 2][3 4][5 6]])
07:00	clojurebot	[[[1 2]] [[3 4]] [[5 6]]]
07:01	pyrtsa	Duh.
07:01	clgv	apply ;)
07:01	pyrtsa	Yep.
07:01	clgv	,(def transpose (partial apply mapv vector))
07:01	clojurebot	#'sandbox/transpose
07:01	pyrtsa	Thanks.
07:01	clgv	,(transpose [[1 2][3 4][5 6]])
07:01	clojurebot	[[1 3 5] [2 4 6]]
07:02	silasdavis	ah very nice, that is how to think of it
07:08	clgv	transpose for list of maps is harder to do correctly ;)
07:14	silasdavis	clgv, not sure how you'd define that
07:15	silasdavis	using the keys as column/row indices
07:15	silasdavis	or treating the map as a sequence of k-v pairs?
07:15	clgv	silasdavis: list of map transposed to map of lists per key
07:15	silasdavis	ah
07:15	clgv	silasdavis: it is not exactly the same
07:15	agarman	that's more a pivot than a transpose
07:16	clgv	but also some kind of transpose and pretty handy for plotting or analyzing attributes ;)
07:16	silasdavis	comes up in exactly the same place though
07:16	silasdavis	if you're returning multiple values
07:16	clgv	agarman: I dont know that meaning of "pivot"
07:16	agarman	in Scalaz that is generalized to a function called sequence
07:17	agarman	clgv: pivot is a rotation of tabular data...
07:18	clgv	agarman: ah ok. might make sense then
07:18	agarman	clgv: not to be confused with a pivot as in quicksort
07:33	clgv	agarman: but transpose is the common principle, I'd say. consider that in the vector case the keywords are the positions ;)
07:43	agarman	clgv: anyhow, if you google with the term pivot, you get fairly relevant results like http://stackoverflow.com/questions/11438918/pivoting-data-via-clojure
07:44	clgv	agarman: yeah, I didnt want to deny that ;)
07:45	agarman	clgv: I'm happy to call it transpose or pivot or yarble, as long as folks know what I'm talking about :-)
07:45	clgv	though that example is doing something different than I meant
07:45	clgv	please not "yarble" ;)
07:47	agarman	clgv: is it that you have a List of Maps and want a Map of Lists...that's https://hackage.haskell.org/package/base-4.7.0.0/docs/Data-Traversable.html
07:47	agarman	:-)
07:49	clgv	yeah that was my initial description. it's getting more complex if you allow non-present keys in some of the maps ;)
07:49	agarman	ah, well good luck :-)
07:49	clgv	already done it some weeks ago ;)
08:06	Morgawr	is there a way to specify the size of the threadpool used by pmap?
08:07	clgv	no
08:07	clgv	Morgawr: if I were you I would not use pmap except for quick and dirty parallelization
08:08	clgv	we need a "pmap considered harmful" blog post
08:08	Morgawr	yeah I know, I'm just working on a study comparing various threading utilities/libraries (Among both java and clojure) and I'm now tackling pmap
08:08	Morgawr	I normally wouldn't use pmap :)
08:08	clgv	just note it as downside ;)
08:08	Morgawr	yeah
08:08	Morgawr	will do
08:09	clgv	it is using one of the threadpools eigther agent or future
08:09	clgv	ah no future^^
08:10	clgv	Morgawr: https://github.com/clojure/clojure/blob/master/src/clj/clojure/core.clj#L6465
08:10	Morgawr	yeah, I'm looking at it now, thanks :)
08:10	clgv	but as far as I added you need to add +1 to that number
08:10	Morgawr	I was kind of hoping it would use the internal threadpool like agents do
08:10	clgv	so in principle it could have a param for that ^^
08:11	Morgawr	but instead it just does its own thing
08:11	Morgawr	yeah
08:11	clgv	it uses the one of futures so it does what you were hoping. but the limit is through the lazy construction there
08:12	Morgawr	clgv: I see
08:12	clgv	Morgawr: just recommend reducers over pmap
08:13	Morgawr	clgv: yeah, definitely
08:40	silasdavis	from time to time I keep restarting lighttable to get a fresh repl and make sure I'm not using any old definitions
08:40	silasdavis	can anyone suggest a good way of getting a fresh environment, either lighttable specific or not
08:40	agarman	fresh
08:41	agarman	and component
08:45	silasdavis	agarman, doesn't sound like it remove existing bindings
08:45	Glenjamin	silasdavis: i tend to just disconnect from repl, and then add a new connection
08:45	silasdavis	I'm also not sure how it would integrate with lighttable which seems to run an nrepl session per file
08:45	silasdavis	or per project
08:45	agarman	Glenjamin: everything is still in the namespace's if you just disconnect
08:46	Glenjamin	right, i mean i kill the repl session without quitting LT
08:47	Glenjamin	i mostly use tools.namespace & a component-style setup, but you don't need to exit LT for a fresh session
08:47	agarman	silasdavis: I tend to leave my various project REPLs running until I reboot my dev box
08:47	_oggy	anybody using instaparse here? any idea how to specify a grammar for "character 'a' followed by exactly one other character (any other)"?
08:47	silasdavis	Glenjamin, what command do you use?
08:48	Glenjamin	silasdavis: "Editor: Disconnect clients attached to editor"
08:50	silasdavis	ah
08:50	silasdavis	ok so when you re-evaluate the namespace it will reconnect
08:50	silasdavis	I think that's pretty decent
08:52	agarman	(inc hyPiRion) ; just discovered cowsay thanks to lein-shell
08:52	lazybot	⇒ 38
08:54	silasdavis	agarman, you might find this useful: https://github.com/erkin/ponysay in an enterprise setting
08:54	agarman	lol
09:03	agarman	(inc silasdavis)
09:03	lazybot	⇒ 1
09:05	hyPiRion	agarman: haha
09:06	agarman	hyPiRion: silasdavis: these are the most amazing utility that I've brew installed this month!
09:42	stompyj	Have there been any good articles on clojure adoption recently?
09:56	johnnyblaze	When using a (map func col) is there a way to know that you are on the last item in the collection?
09:56	toast	not with map
09:56	toast	maybe map-indexed?
09:57	johnnyblaze	K need to look at that haven't used it before. Thanks.
09:57	clgv	johnnyblaze: it's (map f (range) coll)
09:57	toast	It passes the index along with the item
09:58	drbobbeaty	stompyj: What are you looking for - specifically?
09:58	clgv	stompyj: 1 year ago counts?
09:59	stompyj	I don’t even need hard numbers, I’m just trying to convince people here in NYC that clojure is a viable language, and should be in the conversation as people are moving from ruby/python to go/scala
10:00	clgv	stompyj: so you are interested in numbers and not success stories?
10:01	drbobbeaty	stompyj: Well... I've been writing production clojure code for more than a year at Groupon. It's in use in several projects here, including real-time processing of our web and mobile event streams in Storm.
10:01	stompyj	numbers or recent success stories. there was a ton of momentum around core.async and cljs
10:01	clgv	stompyj: http://www.colinsteele.org/post/27929539434/60-000-growth-in-7-months-using-clojure-and-aws
10:01	stompyj	yeah, we’ve been writing clojure here @ indaba for a good 5 months now
10:01	stompyj	and it’s been amazing
10:01	stompyj	clgv: thanks!
10:02	stompyj	and I know movable ink has a big clojure codebase now
10:02	justin_smith	stompyj: we used a lot of clojure when I worked with Instrument, a few of the sites running Caribou (our open source web framework we made for Instrument) are linked on the bottom of the official Caribou site http://let-caribou.in/
10:03	stompyj	How is Instrument? They seem pretty awesome
10:03	justin_smith	now that I mention it, there are more sites that should be added to that list
10:03	justin_smith	stompyj: very hip, very Portland
10:04	justin_smith	sadly, they've gotten big enough that the bigger clients they get now get to dictate the backend stack (or have a legacy backend they have to adapt), so they divested on Clojure (including Clojure devs like me)
10:05	justin_smith	I think they will find long term that was a poor choice, but it wasn't a bad layoff (they gave some severance etc.)
10:06	arrdem	justin_smith: sorry to hear that
10:06	_alejandro	stompyj: We're using it in NYC at Adaptly for a lot of our backend stack too
10:07	_alejandro	stompyj: we switched from mostly ruby; core.async has been great for us in production
10:07	stompyj	justin_smith: wow, that’s sad/ interesting
10:08	stompyj	_alejandro: on the front-end? or back-end?
10:10	_alejandro	stompyj: back-end so far
10:10	_alejandro	stompyj: although I'm pushing for cljs :-)
10:11	stompyj	are you using core.async structures in the req/resp cycle?
10:11	stompyj	or calling out to a persistent service
10:12	_alejandro	stompyj: both
10:15	Nikentic	Hey, I am looking for some learning resources. I've been doing some project euler but I don't really learn any "best practices" or such. Coming from a Python/C++ background.
10:15	Nikentic	Any books maybe? Online courses?
10:15	justin_smith	here's another Instrument site, with clj backend, cljs frontend http://onenorthpdx.com/
10:15	_alejandro	Nikentic: I like braveclojure and joy of clojure
10:15	arrdem	Nikentic: 4clojure comes well commended, but is like Project Euler in that it's just a bunch of exercises
10:15	_alejandro	Nikentic: in that order
10:16	stompyj	_alejandro: wow, I’d love to hear about the in-req-resp cycle stuff at some point
10:16	Nikentic	_alejandro: ok, thank you! arrdem, I'll check that one out!
10:18	_alejandro	stompyj: I'm not sure we're doing it the best way :-), but the request basically triggers a message to be put on a channel, and then the response waits for the output message from an output channel
10:18	_alejandro	stompyj: so there's basically a message 'processor' that is always running, and waiting for input messages
10:21	_alejandro	stompyj: definitely happy to answer specific questions too
10:22	Nikentic	_alejandro: have you got any open source project which source code is useful to read & learn?
10:24	_alejandro	Nikentic: Leinengen, Enlive, and Hiccup are all good, and seem to be recommended by others too
10:25	Nikentic	_alejandro: Leinengen & Enlive for sure. Been looking at some network based code too, pretty interesting
10:25	_alejandro	Nikentic: do you have any other recommendations? I should do more code reading
10:26	Nikentic	_alejandro: No, sorry. I started coding Clojure last week so haven't looked into much
10:26	stompyj	_alejandro: thanks.
10:26	Nikentic	The only code I've read into detail is https://github.com/Raynes/irclj
10:27	Nikentic	riemann is pretty cool too
10:43	mdallastella	caribou has just a couple of dependencies... :D
10:43	benzap	Was wondering, what does the carot simple mean?, like (def ^{:doc "something"} init? true)
10:43	_alejandro	benzap: it's used for metadata
10:44	_alejandro	benzap: http://clojure.org/reader (ctrl+f metadata)
10:44	benzap	_alejandro: ah thanks
10:47	benzap	I was more interested in the form of ^String x, and this seems to explain it
10:48	ddellacosta	benzap: that is type hinting
10:48	TimMc	^String is ^{:tag String}
10:49	ddellacosta	benzap: more here on that specifically: http://clojure.org/java_interop#Java%20Interop-Type%20Hints
10:50	benzap	thank you, i'll give that a read
10:50	clgv	,(.getCanonicalName (Class/forName "[D"))
10:50	clojurebot	"double[]"
10:56	mdallastella	anyway, caribou is quite impressive!
10:59	arohner	what is the best tool for configuring a server these days? pallet, or is there some new hotness?
10:59	mpenet	arohner: ansible is nice to work with
10:59	stompyj	arohner: I’ve been using ansible, to great success
10:59	stompyj	with*
10:59	stompyj	moved from chef
10:59	seubert	another + for ansible
11:00	_alejandro	stompyj: do you use ansible for deployment too? or just config mgmt?
11:00	apetresc	What's the advantage of ansible over chef?
11:00	seubert	apetresc: simplicity
11:00	stompyj	_alejandro: thats why I switched
11:00	apetresc	Ah, okay
11:00	apetresc	But for someone who's already versed in chef, any compelling reason?
11:00	seubert	probably not
11:01	stompyj	apetresc: simplicity also, but writing a script that can both deploy, provision and create an instance was the deal sealer for me
11:01	wkelly	apetresc: ansible is better at orchestrating tasks across multiple servers (do something on server A, then B, then A)
11:01	stompyj	apetresc: if you want to be able to deploy
11:01	wkelly	but if you don't need to do that, then no
11:01	seubert	stompyj: why can't you do that with chef
11:01	seubert	(my chef is rusty at best, honest question)
11:01	stompyj	seubert: early versions of chef had a janky capistrano kind of thing built in, but it never worked, and it seems they’ve deprecated it
11:02	seubert	ah, gotcha
11:02	stompyj	seubert: I always had to do chef + capistrano
11:02	seubert	interesting, i don't recall ever running into that
11:02	seubert	i haven't touched chef in about a year though
11:02	wkelly	I think they are focusing on orchestration for the next release of chef
11:02	mpenet	ansible runs without agents too
11:02	stompyj	seubert: they’re changing it very rapidly, thats another reason why I switched. It broke too often
11:03	mpenet	like pallet too, unlike chef I think
11:03	stompyj	ansible is like a super thin layer over bash scripts
11:03	seubert	this is the biggest reason i never wanted to touch chef again: http://docs.opscode.com/essentials_cookbook_attribute_files.html#attribute-precedence
11:03	seubert	15 levels of precedence and good luck debugging that without stellar internal docs
11:03	seubert	(it's hell)
11:03	stompyj	yeah
11:04	stompyj	the only thing I miss from chef are the detailed recipes, but that’s just a matter of time, until galaxy catches up
11:04	wkelly	no server infrastructure on ansible either, which is nice
11:05	stompyj	yeah, thats another big win
11:05	seubert	chef is faster than ansible if you're touching a lot of boxes since it isn't raw ssh
11:05	seubert	which is both good and bad
11:05	whaley	stompyj: galaxy?
11:05	seubert	whaley: https://galaxy.ansible.com/
11:06	seubert	basically sharing ansible playbooks
11:06	r4vi	doesn't ansible have a 0mq transport- you don'thave to ssh
11:06	stompyj	whaley: its their online repo of recipes. the goal being ansible-galaxy install clojure
11:06	whaley	nod thanks
11:06	stompyj	r4vi: it does. they’re ramping that up going forward
11:06	seubert	ooo i've never used the 0mq part of it
11:06	seubert	that sounds promising
11:06	wkelly	it does have a 0mq transport, but ansible breaks up work into tasks which execute in parallel on all of the nodes and then block until every node compeles the task
11:06	wkelly	I do not think the transport is usually the bottleneck there
11:07	seubert	ah
11:07	seubert	my ignorance is showing
11:07	stompyj	wkelly: yeah, and another tip, this is a huge problem when trying to spin up multiple instances
11:07	stompyj	its actually faster to spin up 1 instance in 4 different shells, then telling the ansible script to bring up 4 boxes at once
11:07	wkelly	hm!
11:08	wkelly	we haven't seen that on rackspace
11:08	stompyj	wkelly: interesting. then maybe it’s just something goofy with ec2, but a single box comes up in 3-5 mins here, but all 4 took about 25-30
11:08	wkelly	(which, disclosure, is the company who I work for, so bias filter appropriately)
11:08	wkelly	that is interesting
11:09	stompyj	ya, its because it was blocking at every step, for some reason
11:09	wkelly	we do a separate provisioning and configuration playbook
11:09	stompyj	to be fair. I didn’t dig into the whys, it may be something I’m (not) doing on my end
11:10	wkelly	this is really the only ansible I have messed with: https://github.com/ludditry/ansible-zwift
11:10	stompyj	yeah, we have a “build ec2 + provision + deploy” script, but then separate scripts for provision and deploying
11:10	wkelly	it spins stuff up on cloud servers for our testing but is generally meant to run on physical machines (deploying openstack swift)
11:10	stompyj	actually, its all the same scripts, we just use tagging to split things out
11:10	stompyj	ahhh very cool
11:10	wkelly	yeah, that makes sense
11:11	wkelly	but in any case, it seems to make networks in parallel, then spin the instances up in parallel, then make/attach block storage in parallel
11:12	wkelly	which does mean that if for some reason one instance doesn't come up, the step fails, and configuration halts
11:13	wkelly	not sure if the ec2 plugins work the same way
11:13	mdallastella	what about fabric?
11:13	stompyj	from what I understand, fabric is more like capistrano, just a deployment tool
11:14	wkelly	I haven't done much with fabric
11:14	mdallastella	stompyj: yeah, right
11:14	wkelly	I am a big fan of dsh or gnu parallel for distribution my sshes :)
11:15	wkelly	er, distributing
11:15	stompyj	nice
11:36	stompyj	Does anyone have any good reference / sites for tweaking the JVM for clojure production deployments?
11:48	erlis	hi guys, quick question. How can I preserve the type of the collection after some operations, for example "map". So if I have a vector I can keep a vector, same for set, hash...
11:48	erlis	any trick ?
11:48	Glenjamin	erlis: you can get a vector with mapv, but in general you'd need (into (empty coll) ...) i think
11:49	erlis	the point is that I don't know the type I have
11:49	erlis	(f coll) -> another_coll same time of coll
11:52	Glenjamin	yeah, (into (empty coll))
11:53	Glenjamin	,(doc empty)
11:53	clojurebot	"([coll]); Returns an empty collection of the same category as coll, or nil"
11:53	erlis	empty!!!
11:53	erlis	great! glenjamin
11:53	erlis	thanks!
11:53	erlis	those little functions that makes your life easier :)
11:54	arrdem	map-into should be a thing..
12:06	johnwalker	arrdem: ehh. in principle i guess, since there are a lot of other strange combinations
12:06	johnwalker	if-not when-not mapv mapcat some?
12:07	arrdem	johnwalker: I mean, not something I'd inflict on the core, but I agree that the core has some strange composed utility functions.
12:08	arrdem	not that I object to the core packaging utility stuff, it's just that the core's in the halfway house of having some utility stuff, not wanting to take more and not having all of the utilities you'd want as amalloy's useful is proof.
12:08	johnwalker	agreed
12:14	kzar	Anyone use Linode here? Recommended? (Sorry very offtopic)
12:15	arrdem	there are a couple of people here who are Linode based and have had good things to say in the past
12:15	arrdem	check the logs
12:16	zaphro	Getting an error with luminus new .... "Could not locate clojure/data/priority_map__init.class or clojure/data/priority_map.clj"
12:16	kzar	arrdem: Oh yea good idea thanks
12:16	arrdem	zaphro: either something has fsck'd dependencies or you forgot to add an explicit dependency.
12:17	zaphro	I haven't reached the deps stage yet. It won't install.
12:18	dbasch	zaphro: what’s the full command?
12:18	zaphro	lein new luminus proj1 +postgres +cljs +site
12:19	dbasch	zaphro: version of leiningen?
12:20	zaphro	(OS X Mountain Lion) Leiningen 2.4.0 on Java 1.8.0_05 Java HotSpot(TM) 64-Bit Server VM
12:20	zaphro	Clojure 1.6.0
12:20	technomancy	zaphro: did you install via homebrew or a manual install?
12:21	toast	erlis, Glenjamin: I used fluokitten to do a map that maintains the collection type, but empty is probably better if it's all you need, since it's there in core
12:21	zaphro	Manual. I've even had luminus install fine before now, ie. before Lein 2.4.0
12:21	kzar	Is there a way to host multiple Clojure web apps on a server with only one instance of Java running, but that at the same time allows you to deploy new versions of each app separately?
12:22	fenrock	immutant is doing work in that area
12:22	kzar	(my VPS is quite RAM limited ATM)
12:22	technomancy	zaphro: very strange; I can't reproduce. can you try with an empty user profile?
12:23	Glenjamin	toast: ah, neat - there's also an fmap in algo.generic
12:23	kzar	fenrock: Is immutant any good?
12:23	zaphro	technomancy Not sure how I do that.
12:23	technomancy	zaphro: mv ~/.lein/profiles.clj ~
12:24	zaphro	technomancy Ah, yes. Will try.
12:24	toast	Glenjamin: yeah, that was it - fmap was the function; next time I'll reach for empty: great suggestion. I'll have a look at algo.generic, too
12:24	fenrock	kzar: only just started using it, 1.x version is JBoss 7 AS based, and i was easily able to deploy and undeploy separate apps. 2.x is alpha and allows you to deploy to non JBoss instances. it works, but i've not used it in anger. they have a channel they are very helpful on if you want to know more
12:25	arrdem	Glenjamin: I love that (fmap IFn IFn) is comp :P
12:25	kzar	Anyone want me to put in their Linode referral code? (Giving it a try)
12:25	kzar	fenrock: cool OK, good to know
12:28	zaphro	technomancy That worked.

12:30	zaphro	technomancy Wondering which one might be the culprit?

12:38	ayia	so I need to find proper comparator for me:)

12:45	gfredericks	Does anybody have any idea how this compojure defroutes expression works? https://github.com/JonyEpsilon/gorilla-repl/blob/develop/src/gorilla_repl/core.clj#L71
12:46	mdeboard	gfredericks: I'm sure someone does
12:46	mdeboard	gfredericks: But, seriously, what do you mean? Like how the defroutes macro works?
12:46	gfredericks	it looks like it just returns a ring handler instead of a response
12:46	mdeboard	in general
12:46	ayia	rasmuto: but seems like I will need my own comparator reimplemented... Because actually I need normal order for the first key, and reversed order for the second key...
12:47	gfredericks	mdeboard: no, I mean that specific usage that I linked to
12:47	Glenjamin	gfredericks: compile-route expands the body with ~@
12:47	Glenjamin	hrm, that shouldn't make a difference
12:47	Glenjamin	https://github.com/weavejester/compojure/blob/1.1.8/src/compojure/core.clj#L101
12:48	gfredericks	I'm not 100% sure this code works; haven't checked out the diff between the version I'm running and the master in this repo
12:48	gfredericks	looking into that now
12:49	Glenjamin	from how i follow this, i agree - there should be another function invocation to make this work
12:50	Glenjamin	,`(~@(fn [a] a))
12:50	clojurebot	#<IllegalArgumentException java.lang.IllegalArgumentException: Don't know how to create ISeq from: sandbox$eval25$fn__26>
12:50	Glenjamin	,(quote `(~@(fn [a] a)))
12:50	clojurebot	(clojure.core/seq (clojure.core/concat (fn [a] a)))
12:51	Glenjamin	,(quote `(let [a b] ~@(fn [a] a))))
12:51	clojurebot	(clojure.core/seq (clojure.core/concat (clojure.core/list (quote clojure.core/let)) (clojure.core/list (clojure.core/apply clojure.core/vector (clojure.core/seq (clojure.core/concat (clojure.core/list (quote sandbox/a)) (clojure.core/list (quote sandbox/b)))))) (fn [a] a)))
12:51	Glenjamin	oh wow
12:51	gfredericks	no I do think this code is working; I just can't figure out how on earth
12:52	mdeboard	that's not good
12:52	CookedGryphon	Does anyone know of a nice efficient immutable (I don't even want to conj) tuple2 thing I could use?
12:53	Glenjamin	CookedGryphon: clj-tuple has that i think
12:53	CookedGryphon	I was using clj-tuple which was great, but won't aot compile, or at least something is exploding in my release build
12:53	Glenjamin	oh, then i dunno
12:53	CookedGryphon	and yeah, even that does too much really
12:54	CookedGryphon	I don't care about doing any manipulations, as soon as it changes I'd want it to just become a straight forward persistentvector
12:54	CookedGryphon	I'm using a simple float[ but that doesn't serialise nicely
12:55	CookedGryphon	otherwise it works perfectly for my needs
12:55	Glenjamin	gfredericks: do you have a running repl for that project? would be good to see what it macroexpands to
13:03	Glenjamin	gfredericks: this seems to work (do (defn func [req] {:status 418}) ((GET "/" [] func) {:request-method :get :uri "/"}))
13:04	Glenjamin	aha, found it
13:04	Glenjamin	there's a call to (render) on https://github.com/weavejester/compojure/blob/1.1.6/src/compojure/core.clj#L94
13:04	gfredericks	Glenjamin: I do
13:04	Glenjamin	https://github.com/weavejester/compojure/blob/1.1.8/src/compojure/response.clj#L30
13:05	Glenjamin	compojure calls (render) on every route, and (render IFn) calls it with req
13:05	gfredericks	Glenjamin: so this is just some weird feature nobody uses that allows you to return a handler?
13:05	Glenjamin	pretty much, although i think i might start using it now
13:05	gfredericks	haha
13:05	Glenjamin	i was trying to figure out how to compose my app the other day
13:06	Glenjamin	ended up using (context) a bit
13:06	gfredericks	Glenjamin: well thanks for investigating
13:06	Glenjamin	you can also return an IDeref according to this
13:08	umpa	How do I get the second value from each vector ? {0 [[0 1 2] [0 3 6] [0 4 8]], 6 [[6 7 8] [0 3 6] [2 4 6]]}
13:09	umpa	in a form of {0 [2 3 4], etc..
13:09	umpa	{0 [1 3 4], etc.. *
13:10	skratl0x1C	How can I create a macro that concats/join/w'ever 2 seqs, one created internally in the macro, the other provided by caller
13:11	skratl0x1C	I tried these https://gist.github.com/skrat/731f2e8e4bfa4e252c67 both fail
13:12	skratl0x1C	the 1st one works when I create the 'headers' vector in the macro calling list, but fails when I give it a var instead
13:13	joegallo	why a macro?
13:15	skratl0x1C	joegallo: because it reads a file and joins its content with the args
13:15	skratl0x1C	it's meant for ClojureScript as a way of embedding assets (GLSL shaders) in the source
13:17	joegallo	umpa: (into {} (for [[k vs] your-thingy] [k (map second vs)]))) is a bit brute-force, but should do the job.
13:22	joegallo	umpa: or for that matter, https://github.com/amalloy/useful/blob/develop/src/flatland/useful/map.clj#L47 would simplify my version nicely
13:22	technomancy	#=(alter-var-root #'clojure.core/loading-verbosely (constantly true)) ; <- clojure.lang.PersistentList cannot be cast to clojure.lang.Var
13:22	technomancy	why is read-eval so weird?
13:23	umpa	joegallo: nice im going to try it both ways.
13:23	technomancy	I get that the reader hasn't been invoked yet, but this breaks too: #=(alter-var-root (resolve clojure.core/loading-verbosely) (constantly true))
13:23	hiredman	technomancy: arguments are not evaluated
13:31	technomancy	yeah... weird stuff
13:37	arrdem	hiredman: ping
13:37	llasram	So it's more like "read–macro-eval"
13:46	Raynes	devn: Holy new clojars.
13:46	Raynes	gg
13:46	arrdem	wp no re
13:48	justin_smith	mdallastella: re caribou, thanks for the feedback, and re "only a couple of dependencies" its a trick, because those deps are just modularized parts of caribou, and in total the deps are actually quite extensive
13:53	dbasch	clojars looks MUCH better
13:55	justin_smith	gfredericks: defroutes is meant to return a handler, that way you can wrap the handler in middleware etc.
13:55	justin_smith	I thought that was like the normal thing to do with compojure
13:56	arrdem	yay even has the markdown badge snip!
13:57	daGrevis	yelp! http://clojuredocs.org/clojure_core/clojure.core/_dot_dot
13:57	daGrevis	what does .. do?
13:57	cbp	(doc ..)
13:57	clojurebot	"([x form] [x form & more]); form => fieldName-symbol or (instanceMethodName-symbol args*) Expands into a member access (.) of the first member on the first argument, followed by the next member on the result, etc. For instance: (.. System (getProperties) (get \"os.name\")) expands to: (. (. System (getProperties)) (get \"os.name\")) but is easier to write, read, and understand."
13:58	pyrtsa	daGrevis: (.. foo bar (baz quux)) is the same as (-> foo (.bar) (.baz quux))
13:58	sorenmacbeth	cccccccc
13:58	justin_smith	pyrtsa: and that is the same as (-> foo .bar .baz quux)
13:58	pyrtsa	justin_smith: Careful!
13:58	justin_smith	?
13:58	justin_smith	that's how the macro works
13:59	pyrtsa	You're right with (.bar) === .bar in there, but quux was an argument.
13:59	justin_smith	ahh, missed that
13:59	justin_smith	because of how the line wrapped
14:00	justin_smith	,(-> "hello" .length .getClass)
14:00	clojurebot	java.lang.Integer
14:00	gfredericks	justin_smith: no it's not that defroutes itself returned the handler, it's that it had: (GET "" [] (return some handler))
14:00	daGrevis	pyrtsa, thanks mate
14:00	justin_smith	ahh
14:01	pyrtsa	daGrevis: I prefer to stick to -> only, but some like .. more.
14:02	daGrevis	pyrtsa, i'm going through om tut for clojurescript and other used ..
14:02	daGrevis	literally i have no idea about whatever :) much magic to me
14:02	daGrevis	s/other/author/ wtf me
14:02	justin_smith	.. is only for method chaining, -> can chain methods and functions
14:02	technomancy	iirc .. is vestigial
14:03	Glenjamin	hah, i like that idea
14:06	kzar	Raynes: cheers dude :)
14:06	Raynes	kzar: ohi there
14:08	kzar	:p
14:14	benzap	was wondering, what's the clojure equivalent of Foo.class, for the class foo?
14:15	hyPiRion	benzap: Foo
14:15	justin_smith	,(= (class "hello") 'java.lang.String)
14:15	clojurebot	false
14:15	justin_smith	,(= (class "hello") java.lang.String)
14:15	clojurebot	true
14:15	hyPiRion	justin_smith: no need to quote it
14:15	justin_smith	right
14:15	hyPiRion	,(= (class "f") String)
14:15	clojurebot	true
14:15	benzap	ah ok
14:16	justin_smith	classes are first class in clojure
14:18	benzap	so (class Foo) and Foo are equivalent?
14:18	hyPiRion	No, (class Foo) is Class
14:18	hyPiRion	,(class String)
14:18	clojurebot	java.lang.Class
14:19	hyPiRion	(class x) means "I want the class of x". If x is a class, then its class is Class.
14:20	benzap	so would (class Foo) mimmick the functionality of Foo.class?
14:20	hyPiRion	Talk about going complete meta there, btw.
14:20	hiredman	benzap: no
14:20	AimHere	,(class class)
14:20	clojurebot	clojure.core$class
14:20	hiredman	String in clojure is String.class in java
14:20	TimMc	,(class nil)
14:20	clojurebot	nil
14:21	hiredman	clojure resolves String to the class object
14:21	benzap	ah, so I just want to call Foo
14:21	benzap	Foo --> Foo.class
14:21	hiredman	no
14:21	TimMc	benzap: Well, you cna't call classes.
14:21	hiredman	classes doesn't implement IFn
14:21	TimMc	benzap: Whatcha trying to do?
14:21	benzap	TimMc: Intent mainServiceIntent = new Intent(context, MainService.class);
14:22	TimMc	benzap: (Intent. context MainService)
14:22	benzap	I have this http://pastebin.com/26rAtQ0E
14:22	benzap	hmm
14:22	TimMc	(class MainService) should be just MainService
14:23	justin_smith	TimMc: it should be java.lang.Class
14:23	justin_smith	oh wait, misunderstood you, n/m
14:23	benzap	so MainService is MainService.class in java, or am I going crazy
14:23	TimMc	benzap: That's right.
14:23	TimMc	justin_smith: I kind of wish (class nil) yielded java.lang.Void
14:24	benzap	so like this http://pastebin.com/WN3rk8xW
14:24	TimMc	It's sooorta what that's for.
14:24	TimMc	benzap: Yep.
14:26	hyPiRion	,(alter-var-root #'class (fn [f] (fn [x] (if x (f x) Void))))

14:27	clojurebot	java.lang.Void
14:27	justin_smith	:P
14:27	hyPiRion	hurray, the return of the nullpointerexception bug
14:28	TimMc	See, shoulda used if-some

14:32	clojurebot	#<ClassCastException java.lang.ClassCastException: java.lang.Class cannot be cast to clojure.lang.IFn>
14:32	Glenjamin	hrm, one sec
14:32	hyPiRion	Glenjamin: what are you trying to do?
14:32	Glenjamin	trying to see what's up with umpa's thing
14:33	TimMc	,(alter-var-root #'class (constantly (fn [x] (if (nil? x) x (.getClass x)))))
14:33	umpa	I am trying to get all the val and do intersection
14:33	clojurebot	#<sandbox$eval363$fn__364 sandbox$eval363$fn__364@101812b>
14:33	hyPiRion	That is probably because the vector contains a single element only, not two elements
14:33	TimMc	,(map class [nil 1 false])
14:33	clojurebot	(nil java.lang.Long java.lang.Boolean)
14:34	Glenjamin	oh right, umpa you need a "k" in that vector
14:34	justin_smith	umpa: that fails at the into {} stage, you are feeding it with a one arg vector
14:34	justin_smith	build up from the inside out
14:35	benzap	i'm extending a class into clojure using (gen-class), if I overload a particular method, and return the wrong type, would you suppose it would return a null pointer?
14:39	justin_smith	benzap: I wonder if it would maybe not be recognized as the method you mean to overload, but a new overload of the method with a different return type. Or maybe trying to do that would be erroneous.
14:39	justin_smith	but unless someone else has a better idea, I'd say try it and see
14:39	benzap	from what I can tell, it doesn't appear to be my problem anyways
14:40	umpa	,(for [v [[1 3 4] [7 3 4] [1 5 4] [7 5 4]]] [(set/intersection #{0 1 2 3} (set v))]) kinda works

14:40	justin_smith	for javac, "The compiler does not consider return type when differentiating methods, so you cannot declare two methods with the same signature even if they have a different return type." - dunno how this applies to the clojure bytecode compiler though
14:41	umpa	,(include 'clojure.set)
14:41	clojurebot	#<CompilerException java.lang.RuntimeException: Unable to resolve symbol: include in this context, compiling:(NO_SOURCE_PATH:0:0)>

14:42	clojurebot	([#{1 3}] [#{3}] [#{1}] [#{}])
14:42	justin_smith	the issue here is that you can't put that in a map, because there are no keys provided, just the vals
14:43	umpa	justin_smith: you mean as set/intersection args /
14:43	justin_smith	umm, no, set/intersection worked just fine there
14:44	justin_smith	I mean the previous thing, where you tried to turn that into a map
14:44	umpa	gotcha

14:55	amalloy	TimMc: i don't understand. were you saying that java.lang.Void is "for" the class of null?
14:56	arrdem	Bronsa: I'm considering patching tanal to add :context types for invoke targets rather than expression forms. Also kinda considering a :binding context. Thoughts?
14:56	arrdem	Bronsa: the problem I'm trying to solve is determining when a {:op :var} is bound to something that's invoked or directly invoked as opposed to taken as a value.
14:57	arrdem	the former probably being a special case that constant propagation would reveal.
14:57	TimMc	amalloy: I was, but I'm not now. I got confused because Clojure treats the value of a void method call as nil.
14:58	amalloy	aww. can't you go back to being wrong? i like educating people
14:58	TimMc	and so many languages do use a nil response instead of having no return value.
14:59	TimMc	amalloy: I can pretend to still hold that opinion if it would make you happy.
14:59	Bronsa	arrdem: interesting
15:01	Bronsa	arrdem: personally, I wouldn't object to that, I can see why that would be helpful
15:01	arrdem	Bronsa: I can trivially collect all {:op :invoke}s and their targets, and I think that if I just treat all vars in binding forms to be taken as values then I would get a _correct_ abet suboptimal analysis.
15:01	arrdem	without patching tanal.
15:01	umpa	justin_smith: something like this should work too right (into {} (for [[k v] {0 [1 3 4], 6 [7 3 4], 2 [1 5 4], 8 [7 5 4]}] [(count (clojure.set/intersection (set comb) v))]))
15:01	umpa	justin_smith: something like this should work too right (into {} (for [[k v] {0 [1 3 4], 6 [7 3 4], 2 [1 5 4], 8 [7 5 4]}] [(count (clojure.set/intersection (set comb) v))]))
15:02	Bronsa	arrdem: it would probably be better to move to namespace qualified contexts at that point, so that we could have :ctx/invoke derive from :ctx/expr
15:02	umpa	,(into {} (for [[k v] {0 [1 3 4], 6 [7 3 4], 2 [1 5 4], 8 [7 5 4]}] [(count (clojure.set/intersection (set comb) v))]))
15:02	clojurebot	#<CompilerException java.lang.ClassNotFoundException: clojure.set, compiling:(NO_SOURCE_PATH:0:0)>
15:02	arrdem	Bronsa: a legitimate use for higherarchies! at last!
15:02	arrdem	:P
15:03	justin_smith	umpa: no, because you still only have one element in that vector
15:03	justin_smith	umpa: maybe you want ((juxt count identity) (clojure.set/intersection ...))
15:04	justin_smith	but then, you would have identical counts clobbering one another, which is why I used reduce instead of for or map in previous examples
15:04	Glenjamin	,(do (require 'clojure.set) (into {} (for [[k v] {0 [1 3 4], 6 [7 3 4], 2 [1 5 4], 8 [7 5 4]}] [k (clojure.set/intersection #{0 1} (set v))])))
15:04	clojurebot	{0 #{1}, 6 #{}, 2 #{1}, 8 #{}}
15:05	umpa	justin_smith: would I need "for" if i used that
15:05	justin_smith	no, reduce and for are two different ways to walk a collection
15:05	Glenjamin	umpa: what is it you're actually trying to do, in terms of data in -> data out
15:08	umpa	Glenjamin: your code gives what I want, maybe vector for the val instead of hash
15:08	umpa	Glenjamin: data in would be a map with key val
15:12	Bronsa	arrdem: as I've said, I'm not against the idea; probably worth discussing with tbaldridge though, I remember him telling me a while ago that Rich was not really happy about the :expression/:statement dichotomy, he might have some valuable opinion on this
15:14	arrdem	Bronsa: willco. Doing this "target rather than value" analysis is a pretty trivial post-walk now that I think about it so I'll just do it in Oxcart and whenever Oxcart get taken apart into contribs we can sort that out if I haven't been able to remove it due to folding.
15:15	Bronsa	arrdem: fine with me
15:15	Raynes	kzar: Turns out there were also breaking changes in that patch release. Oops.
15:16	umpa	Glenjamin: how would I get count of the output vals
15:16	bbloom	Bronsa: i'm not sure i follow your comment about the expression/statement dichotomy as it relates to :context
15:16	dkinzer	fg
15:16	bbloom	Bronsa: are you saying that rich wasn't happy that the analyzer behaves differently with respect to :context ?
15:16	Glenjamin	,(do (require 'clojure.set) (into {} (for [[k v] {0 [1 3 4], 6 [7 3 4], 2 [1 5 4], 8 [7 5 4]}] [k (count (clojure.set/intersection #{0 1} (set v)))])))
15:16	clojurebot	{0 1, 6 0, 2 1, 8 0}
15:16	Glenjamin	like that?
15:17	umpa	Glenjamin: nice
15:17	Glenjamin	if you extract the input into a var with (def), then play around in the repl it should be easier to follow what's going on
15:18	bbloom	Bronsa: looking at tools.analyzer & tools.analyzer.jvm, it seems it only generates :context, never really consuming it except in one place to clear locals... of course the generators are going to care about return position quite a bit
15:19	Bronsa	bbloom: there might be some information loss here since I'm reporting what tbaldridge told me Rich told him, but from what I understood Rich didn't like the fact that ta had an explicit :statement context since Lisps don't really have any statement construct
15:20	arrdem	meh... model != implementation
15:20	bbloom	Bronsa: gotcha. but :statement is really just shorthand for :expr who's value is ignored
15:20	bbloom	:-)
15:20	Bronsa	bbloom: tej uses :statement to understand when/where it needs to pop a value from the stack
15:21	bbloom	Bronsa: yeah, that of course makes sense
15:21	bbloom	instead of :context => :expr :return :statement
15:21	Bronsa	so having it is actually useful
15:21	bbloom	you could have :tail? and :used?
15:21	bbloom	but :tail? true and :used? false wouldn't ever make sense
15:22	arrdem	bbloom: potentially it would if you're inlining or something and the tail value of a subexpression is ignored, ala (do (do .. ) )
15:22	bbloom	hm, that's true
15:22	arrdem	but that's already covered by :ret as opposed to :expr
15:23	Bronsa	bbloom: I don't really see how that would be an improvement over :context :)
15:23	bbloom	yeah, i don't know the precise keywords, just conceptually... what are they precisely? :stmt :ret and :expr ?
15:23	bbloom	this is IMO, the case for making _ a special variable
15:24	bbloom	,(let [_ 1] _)
15:24	bbloom	&(let [_ 1] _)
15:24	clojurebot	1
15:24	lazybot	⇒ 1
15:24	umpa	Glenjamin: yeah repl is nice
15:24	bbloom	c'mon bots
15:24	bbloom	anyway
15:26	bbloom	i'm back, stupid irc
15:26	bbloom	if you say _ is a blackhole value, then do is a special case of let
15:26	arrdem	bbloom: black hole is dangerous in a language where forms must be evaluated for side effects.
15:27	arrdem	then you get silly people like me who want to throw away unreached pure forms
15:27	bbloom	arrdem: it's only dangerous if your optimizer is broken :-P
15:28	bbloom	obviously all clojure forms are lifted in to a context in which JVM effects exist :-)
15:28	bbloom	so really you're getting (JVM ctx ret) and binding ret to _
15:29	bbloom	which means that you really can throw out some work if you're black holign something... as long as you run the expression up to it's last side effect
15:29	tbaldridge	Bronsa: I wouldn't take Rich's problems with :statement/:expression too seriously, it was more off hand. Knowing what I know now I would probably support the way you do it now. It's sometimes easier to do code emission if you know more about the context
15:30	bbloom	,(let [x (atom 1), _ (do (swap! x inc) (swap! x * 2) 123)] @x)
15:30	clojurebot	4
15:30	bbloom	same as:
15:30	bbloom	,(let [x (atom 1), _ (do (swap! x inc) (swap! x * 2))] @x)
15:30	clojurebot	4
15:39	arrdem	Bronsa: okay I can't just clobber :context because I'll break tejvm, so I'm gonna use ::context and lob a :context higherarchy patch at you later.
15:43	Bronsa	tbaldridge: noted, thanks
15:44	Bronsa	arrdem: jeez, make up your mind! :)
15:44	arrdem	Bronsa: quiet you
15:44	arrdem	/s
15:45	Bronsa	I was just getting ready to be offended for life.
15:45	arrdem	as long as you take patches and feature requests I don't really care one way or the other :D
15:46	Bronsa	;_;
15:46	arrdem	<3
15:48	bbloom	i absolutely love that i can prn a GIANT expression to a file, change a boatload of code, then just slurp that expression back in and = it to make sure i didn't break anything
15:48	bbloom	<3 values
16:16	sveri	Hi guys, I am the author of friendui a wrapper which sets a web ui on top of friend and stores the user data in datomic, now, after watching "simplicity matters" the third time it occured to me that I am complecting a friend user interface with datomic and I got the idea to just set a UI on top of friend which accepts some callbacks to load and store user data so that ppl can use every datastore they want, what do you think of this?
16:18	technomancy	I think that writing open source code that depends on proprietary software is silly.
16:20	tbaldridge	sveri: abstraction is often a good idea. Why not use protocols instead of callbacks?
16:20	whodidthis	stupid sexy datomic
16:21	tbaldridge	technomancy: frendui - "a web frontend for friend connected to datomic" kindof seems like the point of the project.
16:22	technomancy	tbaldridge: I understand that
16:22	Glenjamin	abstracting the user storage seems like it would broaden the appeal, certainly
16:23	microamp	tbaldridge: i wonder if rich hickey/cognitect had considered neo4j-like licensing for datamic? (https://github.com/neo4j/neo4j)
16:24	microamp	sorry if it has been mentioned earlier
16:24	kbaribeau	hey, is this a known eyesore with dashes in namespaces and using defrecord/java-interop? https://gist.github.com/kbaribeau/d0d94c02a598490653de
16:24	sveri	I need this library for a private project where we use datomic, however, it occured to me that it might be possible some we may use some different storage in a different project
16:24	sveri	I think I will decouple it
16:25	mdeboard	microamp: I've wondered that myself, but I suppose they want to spend their time building a product vice building a service-oriented company
16:25	sveri	tbaldridge: I have not used protocols yet, my idea was to pass some functions to friendui to retrieve a list of users and things
16:26	tbaldridge	sveri: probably better to define a protocol, and then pass an instance to frendui. That way all the functions are in one thing, instead of having to pass multiple callbacks
16:26	amalloy	kbaribeau: it's a known issue, but it seems to come up pretty rarely, somehow. i guess just avoid putting new types in namespaces with dashes
16:26	sveri	tbaldridge: a protocol that defines functions to retrieve a list of users, save a user instance, update a user instance etc?
16:27	amalloy	usually there's a more clever way to namespace stuff anyway: my.project.protocols instead of my-project.protocols, for example
16:28	tbaldridge	microamp: to be honest, I've never really cared enough to look into it (I'm not part of the Cognitect product team). Personally I've used proprietary software so much in my career using it doesn't bother me at all. Better to use good tech, IMO, then wine about it not being OSS.
16:28	tbaldridge	*whine
16:29	tbaldridge	not to mention that I consider GPL to be a rather horrible license.
16:30	hiredman	tbaldridge: calling open source software advocates whiners seems needlessly pejorative
16:30	kbaribeau	amalloy: thanks, I kind of suspected it might be that way
16:32	catern	hiredman: don't try to correct him - it marks him as stupid very quickly so others don't have to waste time
16:32	arrdem	wooooah
16:32	tbaldridge	hiredman: advocating is fine, complaining that some tech isn't OSS is. If I want to write OSS software that's awesome, but why should I complain when some cool tech isn't?
16:33	tbaldridge	If I spent 2+ years of my life writing some cool tech, why should people complain when I don't want to give away all my hard work? I just don't understand it.
16:33	catern	tbaldrige: things being open source isn't about them being available for free
16:33	microamp	tbaldridge: i see, thanks for sharing your thought btw
16:34	technomancy	well, this is freenode
16:35	TimMc	tbaldridge: Because they want to modify it?
16:35	tbaldridge	catern: in a sense it does, if you read my source, you now know my algorithms. What's left then? patents?
16:35	hiredman	tbaldridge: I think you are painting with a very wide brush there
16:36	hiredman	tbaldridge: open source is a lot of things, but, for example, datomic has free editions you can use, I doubt that in any way has stopped people from asking about it being open source
16:36	tbaldridge	hiredman: agreed, but doesn't everyone on this subject? :-)
16:36	hiredman	so obviously people are just looking to get it for "free"
16:36	tbaldridge	hiredman: why is the free version not enough?
16:36	technomancy	tbaldridge: vendor lock-in
16:36	Glenjamin	because people want to build their businesses on software without paying for it, clearly
16:37	catern	tbaldridge: no, you didn't read what I said. It isn't about getting your algorithms for free. It's about, for example, not tying my company or technology to your whims
16:37	hiredman	tbaldridge: hard to say, I, for example, would just be interested in looking through the code
16:37	arrdem	catern: all you said was that tbaldridge could be discarded as a fool for disagreeing with you :P
16:37	tbaldridge	hiredman: as would I :-)
16:38	hiredman	tbaldridge: for example at work we use elasticsearch rather extensively, and while I don't like doing it, from time to time it is helpful to look through the code instead of treating it as a black box
16:38	catern	arrdem: actually, I foolishly said something else after that, sigh
16:38	Glenjamin	the lock in point seems pretty solid
16:38	dinduks	Hello
16:39	Glenjamin	but i guess that's the price you have to pay if you want to use it
16:40	arrdem	I get the "but I want to modify it" argument, sort of, but I fail to see the lock in one. As Dalvik is unfortunate proof it is possible to do a clean room implementation of a closed API.
16:40	catern	feel free to charge me, please charge me, for commercial access to your open source project. I have no opposition to paying, just to paying for things that don't give me some basic freedoms about how I use them
16:40	tbaldridge	arrdem: or not, since they still got sued for it.
16:41	arrdem	tbaldridge: that's the point unfortunately.
16:41	dinduks	I was wondering if there were CLJS "frameworks" similar to Meteor or MEAN, that can allow fast (and spectacular) development of web apps. Anything?
16:41	gtrak	dinduks: seen om yet?
16:41	technomancy	arrdem: possible doesn't mean practical
16:41	Glenjamin	arrdem: take MySQL for example - people decide they don't like the Oracle direction, so they take the open source and fork
16:41	technomancy	no libre implementation exists in the real world
16:42	arrdem	technomancy: fine, but if you decided it was cost effective you could build one
16:42	tbaldridge	Glenjamin: note that that project started as OSS originally.
16:42	arrdem	technomancy: the point to me of purchased software is rewarding someone else for incurring the risk of building something nontrivial.
16:42	Glenjamin	yes, that's my point
16:42	arrdem	technomancy: and escaping the cost of doing so yourself
16:42	technomancy	arrdem: doesn't mean there's no lock-in
16:42	gtrak	dinduks: I think the closest thing to full-stack is hoplon http://hoplon.io/, look at pedestal too.
16:42	Glenjamin	if its OSS, you cannot be locked in if you don't like the vendor's direction
16:43	Glenjamin	financing OSS is, it seems, a fairly hard open problem
16:43	catern	arrdem: open source software can be "purchased software", weren't you just mentioning neo4j?
16:44	catern	Oh that was someone else. Anyway.
16:44	tbaldridge	Glenjamin: so yes, that's the price you pay with any non-OSS tech. Having used so much proprietary software in my life, and having experienced so little vendor lock-in I guess it doesn't bother me.
16:44	arrdem	technomancy: as long as copyrights and patents don't prohibit clean room implementations (which they seem to do so this is a moot point) my point is that lockin is or should be a non-issue because it's a risk you have to incur if you decide that mitigating that risk by cloning isn't viable.
16:44	Glenjamin	you haven't experienced lock-in, or you haven't had problems because of it?
16:45	technomancy	arrdem: theoretically correct. yet completely impractical
16:45	catern	tbaldridge: doubtful. I think you're just used to the vendor lock in and don't even notice it anymore, you perhaps think that is just how software is
16:45	tbaldridge	But bringing the conversation back around, I just don't understand the need to say "building OSS that requires proprietary software is silly".
16:45	arrdem	technomancy: given that we have retarded IP laws sure
16:45	gtrak	tbaldridge: apparently microsoft is pretty aggressive about deprecating APIs.
16:45	Glenjamin	i agree with tbaldridge there, dependant on proprietary or not, open source is better than not
16:45	technomancy	arrdem: completely impractical even modulo legal issues
16:46	PigDude	what is -Werror in clojure? I have reflection warnings of unknown origin
16:46	hiredman	there is a, I dunno what you call, a margin cost? we store a lot of data on s3 in various formats, I think something like datomics model would work well for us, but it is sort of outside of the use cases that the company seems to be focused on (s3 storage isn't "fast" enough for a real time database backend), and even if it was I don't know that the storage is enough of a problem for us to go out and buy something
16:46	PigDude	i need to see a stacktrace when this happens.
16:46	Glenjamin	reflection warnings usually come with a file and a line
16:46	amalloy	PigDude: there is no stacktrace to be had, because those get generated when your code is being compiled, not when it's being run
16:46	PigDude	that they do
16:47	technomancy	arrdem: that's like saying it's fine to deploy on Windows because ReactOS exists
16:47	PigDude	amalloy: makes sense
16:47	PigDude	amalloy: however this reflection warning comes from inside of clojure.java.jdbc
16:47	Glenjamin	that's odd
16:47	PigDude	amalloy: i guess i do not have the power to correct it if it happens when compiling java.jdbc
16:47	technomancy	curl http://p.hagelb.org/nope.gif \| display
16:48	Glenjamin	PigDude: what version/file/line ?
16:48	tbaldridge	technomancy: are you suggesting it's wrong to deploy Windows?
16:48	PigDude	Glenjamin: 148 in jdbc.clj, where it is parsing a query string. my code doesn't use a query string, so i should've discerned that this is not my problem
16:49	stompyj	(into {} coll) seems quite with large hashes. Is there a quicker way to do this?
16:49	technomancy	tbaldridge: not like ... morally wrong
16:49	Glenjamin	PigDude: in 0.3.3 that function looks to have the correct typehint https://github.com/clojure/java.jdbc/blob/java.jdbc-0.3.3/src/main/clojure/clojure/java/jdbc.clj#L141
16:49	technomancy	just that if you ever find yourself in a position where that seems reasonable, you need to seriously re-evaluate the life choices that led you to this point
16:49	amalloy	Glenjamin: it's https://github.com/clojure/java.jdbc/blob/java.jdbc-0.3.3/src/main/clojure/clojure/java/jdbc.clj#L147
16:49	justin_smith	stompyj: there is also (apply hash-map coll), but into should be faster
16:50	Glenjamin	amalloy: oh right, no hint on the .split retval
16:50	stompyj	justin_smith: I’lll try that, thanks. I would have never guessed that method would so be slow
16:51	Glenjamin	stompyj: have you profiled?
16:51	PigDude	Glenjamin: it is the correspondence between .getQuery and .split, it seems
16:51	amalloy	Glenjamin: well, actually, i guess it's the next line. that first .split is fine, because query's type is known. but the type of kvs is not
16:51	amalloy	(which, by the way, should really be called kv, not kvs)
16:51	Glenjamin	yeah, needs ^String kvs
16:51	PigDude	ah right it's all in the for loop :)
16:52	PigDude	*comprehension
16:52	stompyj	Glenjamin: I just ran (time (into {} return-val)) and it’s taking ~20-30ms
16:52	stompyj	O_o
16:52	PigDude	thanks Glenjamin, amalloy
16:52	Glenjamin	and what is return-val? a large lazy sequence?
16:52	mdeboard	I'd rather read a spirited/occasionally mean argument about OSS than that one ebaums world porn spammer
16:52	mdeboard	or whatever
16:52	mdeboard	that was weird
16:52	stompyj	Glenjamin: yeah
16:52	tbaldridge	technomancy: it's that assumption I kick against. The idea that if I wish to deploy Windows (or proprietary software in general), there is something wrong with me. But we've digressed so much at this point I suppose I should let it drop.
16:53	Glenjamin	you may find that most of the time is reading the sequence, rather than building the map
16:53	Glenjamin	but yeah, jvisualvm is probably a good place to start
16:53	technomancy	eh, kick all you want
16:53	stompyj	awesome, thank you
16:53	justin_smith	PigDude: also, if the coll is lazy, you may find performance is better if you don't hold the head of the sequence
16:54	tbaldridge	technomancy: I see no problem with well written proprietary software. Hence the reason I tend to use Macs over Windows/Linux...it just works for me. I know it doesn't for everyone.
16:54	PigDude	stompyj: ^
16:54	PigDude	stompyj: was for you i think
16:54	amalloy	that sounds like a complete red herring, justin_smith
16:54	stompyj	PigDude / justin_smith thanks
16:54	PigDude	stompyj: heh i didn't help you :)
16:55	justin_smith	oops, I replied to PigDude by mistake about stompyj's question, oops
16:55	michaniskin	is the correct way to deprecate functions demonstrated in the core.memoize https://github.com/clojure/core.memoize/blob/master/src/main/clojure/clojure/core/memoize.clj#L188-L191 ? or is there another, better way i should be doing it?
16:56	tbaldridge	michaniskin: why not just add it to the doc string?
16:56	tbaldridge	michaniskin: and to the changelog. If people don't read the change log, their bad for upgrading before reading.
16:57	michaniskin	tbaldridge: i'd like to have something displayed to the user at compile time telling them how to use the new replacements, maybe? i know people should read the changelog but i thought this might help the rest of the people
16:58	stompyj	Glenjamin: if reading the sequence is indeed the issue, what is the idiomatic way to fix that?
16:58	michaniskin	is it a bad idea to print warnings like this at compile time?
16:59	technomancy	michaniskin: the only danger there is non-aot'ing users might miss it.
16:59	amalloy	stompyj: the point is that producing the sequence may be slow, just because there's a lot of work to do. you can't tell just from running (time (into {} xs)) that anything is slower than it should be
17:00	technomancy	michaniskin: one thing I have done with Lein is have the deprecated function force a delay that prints a warning, so it only happens once
17:00	stompyj	amalloy: hmmm. fair enough, makes sense
17:00	technomancy	michaniskin: I mean when it's run
17:01	michaniskin	technomancy: you're saying if they aren't AOTing the warning might not print when the macro is used? Also, I like the delay idea
17:01	stompyj	as with most things in life, I can fix this by fixing my data model, however, I’m more curious about looking into this behavior, since I hadn’t had to deal with it before
17:01	stompyj	thanks
17:02	tbaldridge	michaniskin: you can do what you want, but if it were me, I'd just rip out the old code, put in the new code, put a note in the changelog and the release email, and reduce the size of that file by 50%. But I can see why you're doing it this way.
17:02	dinduks	gtrak: thanks. i'll check these out.
17:02	technomancy	michaniskin: oh, I missed that it was a macro. in that case compile-time is probably fine.
17:03	gtrak	dinduks: om is hard to search for: https://github.com/swannodette/om
17:03	gtrak	it makes the frontend very fast to build.
17:04	michaniskin	tbaldridge: the old stuff still works fine, but some of the names were really terrible and things like that. i don't mind keeping the old names around forever to keep compatibility but i'd really like to help the user by telling them what the new names are, because i'll be removing the old names from the examples and tutorials etc.
17:20	technomancy	https://i.imgur.com/wfNZNyo.png =(
17:22	gtrak	technomancy: read clojure documentation with Tor.
17:23	technomancy	gtrak: well I don't expect much when I visit clojure.org, but I do have an expectation that I can successfully establish an HTTP connection. =\

17:34	justin_smith	mmmm_: so what's the symptom?
17:34	justin_smith	,(use 'clojure.set)
17:34	clojurebot	nil
17:34	mmmm_	CompilerException java.lang.RuntimeException: Unable to resolve symbol: frame in ... etc
17:34	mmmm_	Leiningen 2.4.2 on Java 1.7.0_55 OpenJDK 64-Bit Server VM
17:34	justin_smith	,(ns-publics clojure.set)
17:34	clojurebot	#<CompilerException java.lang.ClassNotFoundException: clojure.set, compiling:(NO_SOURCE_PATH:0:0)>
17:34	justin_smith	,(ns-publics 'clojure.set)

17:35	justin_smith	mmmm_: if you check the ns-publics, what do you see?
17:35	mmmm_	justin_smith: cannot access symbols
17:35	justin_smith	I mean call (ns-publics 'seesaw.core)
17:35	mmmm_	(ns-publics 'seesaw.core) {foo #'seesaw.core/foo}
17:35	mmmm_	only foo
17:36	justin_smith	mmmm_: did you by any chance try to switch to the seesaw.core ns before requiring it?
17:37	mmmm_	probably not - what is switching? (I call (use 'seesaw.core) before
17:37	justin_smith	try '(require 'seesaw.core :reload)
17:37	justin_smith	without that first '
17:38	amalloy	mmmm_: do you have a file named seesaw/core.clj in your own project?
17:38	mmmm_	did reload - still only foo in the seesaw.core ns
17:38	mmmm_	nope
17:38	mmmm_	ahh yes... aggghhhh
17:39	justin_smith	you shadowed the ns?
17:39	mmmm_	yep
17:39	mmmm_	...
17:40	danneu	oh, so you must've `lein new seesaw` and it created the seesaw.core/foo
17:40	danneu	awesome
17:40	mmmm_	yes
17:41	mmmm_	put to some of your "collected" :)
17:44	danneu	i don't know if i've every really stopped making basic errors that take me 30 min to figure out. like (let [name (:name user)] ...) and then trying to (clojure.core/name ...)
17:46	amalloy	that one's pretty nasty, danneu. i've made it enough times that i generally manage to avoid it or fix it quickly
17:46	amalloy	but it is not a lot of fun
17:47	technomancy	luckily it only happens with that one function =)
17:47	amalloy	i wonder...if i see "String can't be cast to IFn", is that the first mistake i assume i've made? i've kinda grown up enough that i don't really put in too many parens anymore...what else would cause that exception?
17:48	amalloy	passing args in the wrong order, i guess: a string where i meant to put a callable and vice versa
17:48	technomancy	amalloy: someone plz write an nrepl middleware to make fun of you for doing that
17:48	amalloy	it won't be me. i'm pretty sure there's no swank middleware support
17:49	technomancy	maybe that'll be the killer feature that finally gets the slime diehards to upgrade
17:49	technomancy	:repl-options {:sarcastic true}
17:49	amalloy	maybe we can get the vim users on board too
17:49	amalloy	"a sarcastic repl? sign me up!"
17:50	technomancy	"Finally, your editor can be as tired of these type errors as you are."
17:50	arrdem	technomancy: but then we need to get tanal in between the repl and the compiler..
17:50	danneu	i've also run into issues that throw a generic low level clojure error on line 1, column 1 even though it's because of an ad-hoc `(require '[some.ns])` on line 832 i forgot to remove before rebooting my repl
17:50	technomancy	arrdem: nah just hard-code it to the clojure.core/name bug; that's good enough for an 80% solution
17:51	arrdem	technomancy: dude that's not even a 20% solution...
17:51	arrdem	technomancy: lets see you write a regex that tracks bindings..
17:51	technomancy	arrdem: I mean based on the "String can't be cast to IFn" message
17:53	TimMc	technomancy: Match #"^\s+name\s" and #"\[name\s" and I think you've got a pretty good guess at trouble spots.
17:54	arrdem	or you could just use tanal and (ns-maps) to detect all import shadowing :P
17:55	justin_smith	another big one is count - perfectly cromulent as a noun or verb, so very ready to get shadowed
17:57	amalloy	i've done it with map sometimes
17:57	amalloy	which is particularly tricky to track down, because maps tend to be callable and just return stupid results
17:58	justin_smith	ouch
17:58	arrdem	IFn ALL THE THINGS
17:58	justin_smith	ahh, especially as you would normally be doing the three arg version, so you get the unmodified sequence back
17:58	justin_smith	lol
17:59	cbp`	except for regex ;(
17:59	amalloy	yep
17:59	seangrove	arrdem: Strings implemented IFn in cljs for the longest time
17:59	seangrove	Fun times
17:59	arrdem	RFC: me.arrdem/regular: crowbars int core and implements IFn for regexes :P
17:59	arrdem	s/int/into/g
18:00	technomancy	nothing has ever made me sad about not using cljs like callable regexes
18:02	dgleeson	so when you return a 404 using ring it doesn't add the extra tomcat formatting. I'm curious if anyone has experience munging the error codes so they look like tomcat's default presentation?
18:03	justin_smith	dgleeson: how are you returing the 404 status? {:status 404} with no body key?
18:05	gtrak	tanalysis
18:06	dgleeson	{:status 404 :body "some message"}
18:06	dgleeson	if I return just a status code it's a blank page
18:07	justin_smith	dgleeson: oh, I had hoped that might cause it to use the default 404 body
18:09	dgleeson	My other java servlets use the HttpServletRequest/sendError work flow
18:09	dgleeson	which triggers it
18:10	dgleeson	but since ring-servlet wraps that with a map, I'm not exactly sure how to trigger that code path
18:23	seangrove	dnolen_: Might be time to bump mies-om template
18:28	kzar	Raynes: :o did I mess something up?
18:28	Raynes	kzar: Nope, it was a previous pull request by someone else.
18:28	Raynes	Just changed some var names.
18:28	Raynes	I had forgotten about it was was like "RELEASE! RELEASE! RELEASE! SHIPIT!"
18:28	Raynes	Nothing to be done about it now.
18:29	kzar	llol
18:32	dnolen_	seangrove: ah right, thanks for the reminder
18:32	seangrove	dnolen_: No worries, just coming back to it after some time in the js world
18:38	noncom\|2	does anyone know anything about DotLisp?
18:39	noncom\|2	what's the project status?
18:40	justin_smith	noncom\|2: interesting, looks like a clojure predecessor
18:41	noncom\|2	yes, it is, i am to ressurect it for my practice - i have to work with unity3d, which is based on mono, which is based on net framework 2. so far, dotlisp is the only sane lisp for net i have found (besides ironscheme)
18:41	noncom\|2	coincidently, it is made by the same man :)
18:42	noncom\|2	its crucial +s are 1) net 2.0 compatibility and 2) lightweighness like never before
18:42	noncom\|2	so i wanted to know what's up with it officially
18:42	justin_smith	noncom\|2: what about the clojure clr backend?
18:43	justin_smith	is that just not usable?
18:43	noncom\|2	too bad, but clojure clr requires net 3.5+, it will not work in unity3d
18:43	noncom\|2	also, we target android...
18:43	noncom\|2	so dotlisp seemes to me like a neat little brother (or sister) of clojure
18:44	noncom\|2	the standard boot.lisp defines much, but i am writing boot2.lisp which brings it closer to clojure in terms of functionality
18:44	noncom\|2	since i'm used to clojrue :)
18:44	noncom\|2	ofcourse, no stm and such, but unity3d hardly requires it
18:45	noncom\|2	i wrote a mail from the sourceforge site to both maintainers, but no answer yet...
18:46	noncom\|2	i thought about ressurecting it and creating a good unity3d support
18:46	noncom\|2	currently unity3d lacks lisp
18:47	noncom\|2	so i thought maybe anyone knows, how can i write a mail to rich about it, since that project did not seem to have any community at all..
18:55	TEttinger	noncom\|2, are you sure unity allows anything but C#, Boo, and UnityScript?
18:55	TEttinger	I think it has arbitrary constraints
18:56	noncom\|2	well, firstly it is based on an ancient mono version, which is about framework 2
18:56	noncom\|2	all clr langs moved far since then, as did clojure
18:56	noncom\|2	but i want a lisp with a repl
18:56	noncom\|2	the only 2 sane candidates are dotlisp and ironscheme
18:57	noncom\|2	ironscheme is another story, lets discuss dotlisp
18:57	TEttinger	right but I have never heard of anyone being able to use anything but those 3 in the unity environment
18:57	noncom\|2	i have managed to implement a repl and it wokrs perfectly fine
18:57	noncom\|2	i already can do anything with it
18:57	TEttinger	mono has a C# repl actually
18:57	noncom\|2	but not for unity3d :)
18:57	TEttinger	:-(
18:58	noncom\|2	actually, unity3d is a piece of ancient crapware
18:58	noncom\|2	(dont tell anyone)
18:58	TEttinger	why not libgdx if you're using clojure?
18:58	hiredman	b
18:59	noncom\|2	currently i have a project with libgdx and i also use jmonkey when appropriate, that is fine. but there is a second story in my life - my new employee is based on unity3d
18:59	noncom\|2	i am actually a jvm + clojure guy
18:59	TEttinger	heh ok
18:59	noncom\|2	but forced to work for a unity3d c# company
18:59	TEttinger	C# isn't that bad, tbh
18:59	noncom\|2	if i propose the initiative inside the company, they will accpet it
18:59	TEttinger	LINQ is a nice breath of functional air
19:00	noncom\|2	well, i do not like it much, but yeah, the language is ok, on par with java
19:00	noncom\|2	but there are other implications too..
19:00	noncom\|2	using a lisp will help us much
19:00	noncom\|2	and also, i just want to work with a lisp
19:00	noncom\|2	:)
19:01	noncom\|2	you should try unity3d if you did not have a chance yet
19:01	noncom\|2	to see all its crappyness
19:02	TEttinger	heh, I was going to, but I'm sticking with either C#/MonoGame or Java/Clojure/LibGDX
19:02	noncom\|2	i vote for java :) since i worked 3 years in that field - java/clojure/jme/libgdx
19:03	noncom\|2	i think that seeing some unity3d is useful in terms that you can learn, how you should NEVER design your software
19:03	noncom\|2	it has some good spots though
19:03	noncom\|2	but they jsut dont cut it
19:15	deathknight	(format "test/%s/foo")
19:15	deathknight	what does %s mean?
19:15	arrdem	format in a string here
19:15	deathknight	is there a term I can look up that explains what you just said?
19:16	cbp	deathknight: http://docs.oracle.com/javase/7/docs/api/java/util/Formatter.html
19:16	arrdem	java.lang.String.format
19:17	deathknight	still dont quite understand
19:18	deathknight	specific example: (api/simple-request (format "/calendars/%s/events" (api/decode cal)) token)
19:18	deathknight	is token being placed where the %s is?
19:18	cbp	no, (api/decode cal) is assumed to be a string and placed where the %s is
19:18	deathknight	NICE
19:19	deathknight	thank you!
21:38	Fare	hi
21:39	catern	hi
21:39	Fare	which clojure deftype vs defrecord vs ... to use for data with inheritance of fields?
21:43	justin_smith	Fare: if all you need to do is inherit some default values, you can just call merge on a map
21:43	hellofunk	Fare: while polymorphism is quite nice in Clojure with defrecord, inheritance is a different matter and I think generally not recommended
21:43	hellofunk	as justin_smith notes, using data instead of object-oriented ideas tends to be more idiomatic in Clojure
21:45	Fare	so more like, include a subrecord?
21:45	Fare	e.g. if I want each record to contain provenance information
21:46	hellofunk	learn all the functions on maps and you'll likely find some good ones for your purposes. assoc, dissoc, merge might be useful: Fare
21:46	justin_smith	until you absolutely need the performance benefits of a custom deftype or defrecord, use a map, and write a function that makes a map of the right shape
21:47	justin_smith	using maps and using types / records happens to have identical semantics, so upgrading is not very hard
21:48	justin_smith	if you want, you can even name the function returning the map "constructor"
21:48	hellofunk	note that while defrecord supports associative functions, deftype is a much simpler API; I don't think assoc etc work on deftype?
21:48	justin_smith	hellofunk: ahh, good call, maybe not
21:48	justin_smith	that's probably why I have never used it actually
21:49	justin_smith	anyway, at worst it's a question of (.slot thing) vs. (:slot thing)
21:49	hellofunk	generally deftype is not going to be useful unless you want to, for example, write a Clojure compiler for a different platform, you can build out your base with custom types
21:49	justin_smith	(for access that is)
21:51	justin_smith	as I don't use deftype much, this is a helpful reminder of how they work / compare http://clojure.org/datatypes
21:54	justin_smith	Fare: especially not the heading on that page "Datatypes and protocols are opinionated"
22:00	deathknight	using http.async.client, how do I specify the content-type as JSON?
22:03	justin_smith	deathknight: (http/POST client "url" :body [{:mime-type "application/json" ...}])
22:03	justin_smith	https://github.com/neotyk/http.async.client/blob/development/docs.org
22:06	deathknight	I...am...so close....thank you Justin!
22:06	deathknight	If my body already looks like this, should I still put a vector around it with the inclusion of mime-type? :body {:end {:date "2014-06-16"} :start {:date "2014-06-16"}}
22:07	deathknight	or would this work-- :body {:mime-type "application/json" :end {...}...}
22:08	Fare	clojure in some ways seems to be miles ahead, and in other ways, lagging.
22:08	Fare	I'm not yet sure exactly which though.
22:09	justin_smith	Fare: I think clojure is much more opinionated
22:09	Fare	is that your opinion?
22:09	hellofunk	Fare, which ways do you feel clojure is lagging?
22:10	hellofunk	it is fair, Fare, to say that clojure is a bit more encouraging to a particular programming style than is CL
22:10	justin_smith	deathknight: I think the way it works is you make a :query that consists of some magic key, so it's :query {:request (your map that bcomes json here)}
22:11	deathknight	hmm
22:11	deathknight	looks a bit different than what I'm working off of that works so it's a bit over my head :)
22:11	justin_smith	hellofunk: two ways that I would agree clojure is lagging is startup time and step debugging
22:11	deathknight	I'm doing some finicky balancing on these shoulders
22:12	justin_smith	deathknight: heh, OK
22:12	justin_smith	deathknight: http://neotyk.github.io/http.async.client/doc/http.async.client.html#var-POST
22:12	justin_smith	that's pretty comprehensive I think
22:12	hellofunk	it's definitely true that Clojure debugging is pretty primitive
22:12	deathknight	Danke!!
22:24	deathknight	so even though content-type is usually defined in the headers, http.async.client has it chosen in the :body?
22:24	justin_smith	the docs may be wrong?
22:24	deathknight	oh! what you were saying earlier with :query!!!
22:24	deathknight	the json data goes in that!
22:25	deathknight	holy topanga!
22:25	justin_smith	yeah, query is just part of the body I guess?
22:25	hellofunk	no, when you see a specialist and he says you have the flu and it turns out to be typhoid, then the docs are wrong
22:25	deathknight	LOL
22:27	hellofunk	i'm just sayin
22:29	deathknight	So I'm getting clojure. Right now my :body is throwing this-- IllegalArgumentException No matching clause: http.async.client.part/create-part (part.clj:42)
22:29	deathknight	:body [{:mime-type "application/json"}]
22:29	deathknight	and here are the docs referencing create-part -- http://neotyk.github.io/http.async.client/doc/http.async.client.part.html
22:29	deathknight	getting closer*
22:30	justin_smith	oh, in order to submit json does it need to be multipart?
22:31	Fare	well, I miss CLOS
22:31	deathknight	I have no idea
22:31	Fare	I really like the everything-pure-by-default of Clojure.
22:31	Fare	I don't understand protocols yet.
22:32	Fare	is there no inheritance of methods?
22:32	hellofunk	Fare records and protocols are basically the decoupling of object properties and object methods, makes things a lot more simple and flexible. Can adopt as many protocols as you want.
22:32	justin_smith	a protocol is a more clojure-y view of an interface, which is a class but not really that is there for implementing rather than inheriting from
22:33	deathknight	what multipart type would json require?
22:34	hellofunk	Fare it depends on how you need inheritance. in many languages, inheritance is a prerequisite for polymorphism, and if polymorphism is what you need, you get that in clojure with multimethods without using inheritance
22:35	Fare	no, I want mixins, just like I can have with CLOS.
22:35	Fare	mixins are good.
22:35	Fare	multiple inheritance
22:36	Fare	is there anything in clojure that will let me do multiple inheritance?
22:36	Fare	(I suppose I could roll my own on top of maps using macros... bleah)
22:36	hellofunk	Fare, well again it depends on what you need, exactly. You can certainly adopt multiple interfaces, which is similar to multiple inheritance in some languages.
22:37	gfredericks	Fare: the hierarchies used by multimethads support multiple inhertance
22:37	gfredericks	,(derive ::square ::shape)
22:37	clojurebot	nil
22:37	gfredericks	,(derive ::square ::word)
22:37	clojurebot	nil
22:37	Fare	hellofunk, except that in CLOS, I can inherit multiple interfaces AND their default (and/or next-method) implementations
22:38	gfredericks	,(defmulti describe :type)
22:38	clojurebot	#'sandbox/describe
22:38	gfredericks	,(defmethod describe ::shape [_] "it is a shape")
22:38	clojurebot	#<MultiFn clojure.lang.MultiFn@195d263>
22:38	hellofunk	Fare as gfredericks mentions, check out the derive methods
22:38	gfredericks	,(describe {:type ::shape})
22:38	clojurebot	"it is a shape"
22:38	Fare	ok
22:38	Fare	thanks!
22:38	gfredericks	,(defmethod describe ::word [_] "it is a word")
22:38	clojurebot	#<MultiFn clojure.lang.MultiFn@195d263>
22:38	gfredericks	,(describe {:type ::square})
22:38	clojurebot	#<IllegalArgumentException java.lang.IllegalArgumentException: Multiple methods in multimethod 'describe' match dispatch value: :sandbox/square -> :sandbox/shape and :sandbox/word, and neither is preferred>
22:39	gfredericks	,(prefer-method describe ::word ::shape)
22:39	clojurebot	#<MultiFn clojure.lang.MultiFn@195d263>
22:39	gfredericks	,(describe {:type ::square})
22:39	clojurebot	"it is a word"
22:40	bbloom	Fare: i'm not saying that next-method et al aren't ever useful, but they are A LOT LESS USEFUL than you'd think in clojure
22:41	bbloom	Fare: it's also pretty easy to merge maps & use ##(doc extend)
22:41	lazybot	⇒ "([atype & proto+mmaps]); Implementations of protocol methods can be provided using the extend construct: (extend AType AProtocol {:foo an-existing-fn :bar (fn [a b] ...) :baz (fn ([a]...) ([a b] ...)...)} BProtocol {...} ...) extend takes a type/class (or interface,... https://www.refheap.com/86698
22:41	bbloom	so if you really do need concrete "inheritence" you can simply compose maps & call extend
22:41	bbloom	requires some pre-meditation, but the results are much simpler
22:41	bbloom	again, i've only ever needed to do this once in practice
22:42	gfredericks	bbloom: is that how CinC would likely handle ASeq and other inheritance patterns in the java code?
22:43	bbloom	gfredericks: one possible way, sure
22:43	deathknight	"post request requires a content-length header"
22:43	deathknight	justin, does that ring a bell? :O
22:43	bbloom	gfredericks: problem is that for the core-most parts of clojure, best perf is given if interfaces are implemented when classes are defined
22:44	bbloom	gfredericks: protocols really are quite fast, but for code that is on ALL USERS critical path, the small overhead isn't worth it
22:44	bbloom	so it's more likely that there'd be some macro-fu with quoted code
22:44	gfredericks	bbloom: ah ha right
22:45	gfredericks	they'll have to bring in ztellman
22:45	amalloy	gfredericks: ztellman has abandoned protocols, last i checked
22:45	amalloy	uses interfaces instead
22:45	gfredericks	amalloy: sure
22:45	gfredericks	replacing java with a few nested backticks
22:46	bbloom	speaking of odd things w/ protocols
22:47	bbloom	https://github.com/clojure/clojure/blob/master/src/jvm/clojure/lang/AFunction.java#L20
22:47	bbloom	that's only ever used for protocol stubs
22:47	bbloom	seems kinda weird to throw an extra field on every function ever
22:49	bbloom	closing over values makes fields, but you can't have a mutable local... and since protocols are mostly defined in clj, every function gets a bonus mutable local in case it might be used for a protocol
22:49	bbloom	and then ztellman shows up again: https://github.com/ztellman/proteus
22:49	hellofunk	this is some pretty great info
22:50	amalloy	bbloom: do you know if protocol functions still get callsite method caches?
22:51	amalloy	like, when i write (fn foo [] (proto 1)), where proto is a protocol function, does the class generated for foo's implementation have fields for caching the most-recently-used protocol definition?
22:51	gfredericks	amalloy: isn't that what he linked to?
22:51	amalloy	gfredericks: no, that's a single cache on every function
22:52	gfredericks	and you're talking about a static field?
22:53	amalloy	i'm talking about multiple fields, one for each protocol function that is called
22:53	gfredericks	ah hum
22:53	amalloy	a quick disassemble suggests this is no longer the case
22:54	bbloom	amalloy: i haven't studied the compiler side of protocols too closely yet
22:54	gfredericks	would The BBloom Field serve that purpose then?
22:54	gfredericks	or does it do something else I forgot to understand?
22:54	bbloom	that field is a per-method cache
22:54	bbloom	not a per-callsite cache
22:54	amalloy	a year or two ago things were arranged such that if you wrote a function that called ten protocol functions, you got like thirty fields, three each for caching each call site
22:55	gfredericks	so what does The BBloom Field accomplish?
22:55	bbloom	side note: if you deftype, then extend-protocol, and keep re-evaling that file while you work... you leak memory :-P
22:55	amalloy	which is fine for functions with only one instance, like (defn foo), but is terrible for lambdas that get returned, or things which are instances of a defrecord
22:55	bbloom	not a lot, but a leak is a leak
22:55	bbloom	,(defprotocol P (f [x]))

22:57	gfredericks	do old classes normally get GC'd?
22:57	bbloom	i have no idea
22:57	bbloom	i hope so
22:57	amalloy	gfredericks: yes, if there are no references to them
22:58	gfredericks	okay so this is a leak not just in the size of that hashmap but also the classes not getting GCd
22:58	bbloom	gfredericks: right
22:58	bbloom	b/c the keys are actually the types
22:58	bbloom	i dunno if this is filed anywhere
22:58	bbloom	not sure if it matters really though
22:59	Fare	I like the first-class class thing
22:59	bbloom	Fare: that's just standard java
22:59	bbloom	and it should be standard everything, since it was standard in smalltalk back when :-P
22:59	Shayanjm	I wish lighttable addressed issues faster
23:06	trptcolin	bbloom: wow that definitely explains some stuff i’d seen w/ reloading locally
23:06	bbloom	trptcolin: what have you seen?
23:06	trptcolin	i’d assumed it was something in here: http://dev.clojure.org/jira/browse/CLJ-1152
23:07	trptcolin	permgen exploding
23:08	hellofunk	Shayanjm agree. I really have high hopes for light table but my reported issues appear ignored and some things bother me too much, so I switched back to emacs.
23:08	bbloom	trptcolin: if you can create a small project that exhibits the problem in a bad way, please go ahead and file the ticket :-)
23:08	Shayanjm	hellofunk: I'm trying to dive into clojure, and have been using lighttable for its instarepl thing
23:08	Shayanjm	but I actually discovered a discrepency in their repl vs. the repl provided by lein
23:08	Shayanjm	(which I would assume is a pretty big issue)
23:08	hellofunk	Shayanjm what kind of discrepancy?
23:09	Shayanjm	https://github.com/LightTable/LightTable/issues/1520
23:09	hellofunk	Shayanjm light table is nice for quick start in clojure learning, i like its built-in docs and the automatic inline autocompletion and documentation
23:09	bbloom	hellofunk: don't use `ns to switch between namespaces

23:10	trptcolin	bbloom: trouble is, (1) it’s just a dev-time thing, (2) it’s with a non-core unit testing library (3) restarting my local test process gets me working again, (4) i’m not even working on that project these days.
23:10	bbloom	trptcolin: yup, dev-time only issue... there are way worse problems that prevent "never restart a repl" from being a reality
23:11	loliveira	hi, does anyone know why i’m getting this error: https://www.refheap.com/86699 ? I am new to clujurescript.
23:11	hellofunk	Shayanjm in your posted issue, it's not clear that you may not have re-evaluated your defs after you switched to the new namespace
23:11	hellofunk	You certainly could have, and maybe you didn't, but if you had, then they'd appear in the new namespace
23:12	bbloom	trptcolin: there, i added a bullet point here: http://dev.clojure.org/display/design/Never+Close+a+REPL
23:12	bbloom	rather than make an issue, since it will never get fixed :-P
23:12	Shayanjm	hellofunk: That's a good point, I'm not sure if the instarepl automatically re-evaluates every def
23:12	trptcolin	these days i basically only file issues that either force me to monkey-patch core or that i’m certain are bugs that i have the correct fix for
23:12	bbloom	it's a shame, but me too
23:13	hellofunk	Shayanjm in any case, emacs is a much much smoother editor overall
23:13	bbloom	Shayanjm: i meant that msg for you, not hellofunk
23:13	hellofunk	in light table, the actual emphasis on fonts seems to change as you cursor through the code, which is ridiculous.
23:14	Shayanjm	bbloom: oh, I see. I mean either way, that doesn't address the discrepency between Lein & Lighttable REPLs
23:14	Shayanjm	there's no reason for one to evaluate differently to the other given the same set of commands
23:14	Shayanjm	hellofunk: I should probably pick up emacs then. I'm an ST3 user and thought Lighttable looked interesting
23:14	bbloom	Shayanjm: i think light table does some "clever" bits with respect to ns forms
23:14	hellofunk	Shayanjm bbloom i re-iterate that your test in those screenshots is not a good one unless you are certain the defs were not re-evaluated after you switched ns
23:15	technomancy	hellofunk: how is re-evaluating defs after switching namespaces not broken behaviour though?
23:15	Shayanjm	^
23:15	hellofunk	technomancy he could have actually re-evaluated the defs manually in the instarepl since they are right there, isn't it easy to evaluate any line in the instasrepl?
23:16	technomancy	Shayanjm: you could check using (meta #'thing2) though just to see what flavour that particular brokenness happens to take
23:16	Shayanjm	hellofunk: All of the code in the instarepl was written inline
23:16	Shayanjm	and the issue can easily be replicated
23:17	hellofunk	Shayanjm i will try it out right now on my light table out of curiousity.
23:21	hellofunk	Shayanjm ah, in live mode as you are typing the refer statement, it will refer everything before you get to the :only part of the forum
23:21	hellofunk	*form
23:21	Shayanjm	oh fucking hell
23:21	hellofunk	this is not a bug, it is by design, that is what the "live" mode does
23:21	Shayanjm	well that actually makes me feel a lot better
23:22	hellofunk	you can turn off the live mode, of course
23:22	Shayanjm	thanks for investigating hellofunk
23:22	loliveira	any help? https://www.refheap.com/86699
23:22	hellofunk	Shayanjm i'd recommend updating or closing your Github issue
23:22	hellofunk	it's not a bug
23:22	Shayanjm	Doing so right now
23:23	technomancy	hellofunk: does it eval it before the paren is closed, or is it eval-able because of paredit-ish stuff?
23:23	hellofunk	technomancy it evals immediately everything you type inside a form, and the close paren is already there due to paredit
23:23	hellofunk	it will re-evaluate on every keystroke
23:23	technomancy	wow
23:24	hellofunk	hence the "insta" in "instarepl"
23:24	hellofunk	But there is a Live button right there up front for turning that off
23:24	technomancy	does it have a failsafe to autodetect rm -rf calls? =)
23:25	hellofunk	The screenshot in the github issue indicate that Live mode was on for the test
23:25	hellofunk	Light table is quite interesting and nice in many ways, but my workflow is better for now with emacs
23:26	deadghost	http://stackoverflow.com/questions/24254689/change-vectors-to-lists-using-postwalk
23:27	deadghost	does this count as a bug and should I report it somewhere?
23:28	hellofunk	Part of the problem with Light Table is that it's most important part - the code editor - is not even written in Light Table. It's a third-party open-source JS library. And the code editor is not that good IMHO. Chris has said that if you want to see the editor improve, you should support that other library as well. And so it's a trickle-down problem of quality.
23:29	deathknight	Getting "UnsupportedOperationException nth not supported on this type: Character" when introducing JSON to an HTTP POST request
23:29	danneu	can anyone provide a db-spec string/map example they're using to connect to their heroku postgres db remotely (i.e. from their laptop)? been at it for an hour with no success
23:29	deathknight	(cheshire :) )
23:29	Jaood	my issue with LT is that it doesn't run in the terminal :P
23:31	ddellacosta	danneu: this used to work for me, no promises as I haven't used heroku lately: https://www.refheap.com/06d7b4600d81d539106b29669
23:32	ddellacosta	danneu: ah, sorry, you said remotely from laptop?
23:33	ddellacosta	danneu: like in your repl?
23:36	hellofunk	ddellacosta what would be the clojurescript equiv of this JS: var client=new ClientMsg({"logon": toLogon}); -- can it be done in a single line?
23:36	danneu	ddellacosta: yeah. i'm on a scavenger hunt to find the magical incantation. i've tried things like merging in {:ssl true, :sslfactory "org.postgresql.ssl.NonValidatingFactory"} from old stackoverflow answers, but no luck
23:37	ddellacosta	hellofunk: (let [client (ClientMsg #js {:logon toLogon})] ...) I guess?
23:37	ddellacosta	danneu: hmm, well, maybe that article at the link in my example could help, and maybe there are some clues in there, but that is for connecting to the db on heroku, sorry. :-(
23:37	hellofunk	ddellacosta would you need a dot, ClientMsg. since it is a "new" JS form? My JS is quite bad to be honest
23:37	ddellacosta	hellofunk: sorry, should probably be ClientMsg.
23:37	ddellacosta	yeah
23:38	hellofunk	cool thanks
23:45	deathknight	holy crap, it's the ddellacosta _
23:46	deathknight	did you write the friend-oauth2 examples? I can't remember what project I saw your name attached to
23:47	hellofunk	ddellacosta do you ever get to a point where the browser just shows exceptions on the ring server and without changing code, restarting the browser resolves them? has started happening to me recently, rather odd. no need to restart the Ring server, just the browser.
23:47	danneu	ddellacosta: finally gathered all the pieces https://gist.github.com/danneu/c3d1b15d0b977ee3a154
23:47	ddellacosta	deathknight: yes, I wrote that. I really have to update that, got some outstanding pull requests. :-(
23:47	deathknight	I just emailed you about the issue/4! and I figured it out! woohoo
23:47	deathknight	(yesterday, I believe)
23:47	ddellacosta	hellofunk: can't say I have seen that...sounds quite strange
23:47	ddellacosta	deathknight: excellent. :-)
23:48	deathknight	what's your preferred HTTP client?
23:48	deathknight	I'm using http.async.client and I'm failing at making a POST to google calender
23:48	ddellacosta	deathknight: I don't know that I've tried that, I've only used clj-http I believe
23:49	ddellacosta	danneu: so, does that db-spec work when you use say, clojure.java.jdbc to connect?
23:49	ddellacosta	deathknight: are you Harry?
23:49	deathknight	Henry :)
23:50	ddellacosta	deathknight: ah, okay! sorry I didn't respond sooner, but glad you got it worked out. :-)
23:50	deathknight	tis all gravy
23:50	ddellacosta	deathknight: sorry for screwing up your name too...haha
23:50	deathknight	now it's brimstone
23:51	ddellacosta	deathknight: you are very dark, with your deathknight and brimstone. Kind of a different vibe than Henry. ;-)
23:51	danneu	ddellacosta: yeah, i use clojure.java.jdbc directly - https://gist.github.com/danneu/c3d1b15d0b977ee3a154
23:52	ddellacosta	danneu: gotcha, so you can basically run migrations locally for your remote heroku db? I never thought of that but that would have solved a lot of problems I had in the past. Very nice.
23:53	danneu	ddellacosta: the real reason is that i like to develop straight against my remote dev server.
23:53	loliveira	resolved adding thre folowing dependency: [com.google.guava/guava "17.0"]
23:53	deathknight	ddellacosta: it would cool the embers in my soul if you could try to convert this to clj-http's version of a POST request: http://pastebin.com/5mRwMFwX
23:54	ddellacosta	deathknight: well, I think it's pretty straightforward--have you checked out the docs here? https://github.com/dakrone/clj-http#usage
23:55	ddellacosta	deathknight: if you give that a shot and have trouble I'm happy to help, but I'll make you do the initial work. ;-)
23:55	deathknight	:)
23:55	deathknight	that is a smile of vengeance
23:55	ddellacosta	hahaha
23:55	deathknight	I'm going to take you up on that offer
23:55	ddellacosta	deathknight: alright, sounds like a plan.
23:55	deathknight	:)
