01:44	gratimax	anyone seen this? http://clochure.org/
01:47	dstockton	yes
01:48	wasamasa	lol
01:49	wasamasa	and what's their vector syntax then?
01:50	wasamasa	ah, it's (2 3 4)
01:50	gratimax	parentheses
01:50	wasamasa	so silly
01:50	gratimax	I'm like 90% sure it's an april fool's joke of some sort, just thought it would be fun to share
01:51	dstockton	it was an april fools joke
01:51	dstockton	https://github.com/videlalvaro/clochure/
01:52	gratimax	mm
01:52	gratimax	lol, in the repl the output is still the clojure representation
02:47	wasamasa	of course
02:48	wasamasa	how else are you gonna now it's working??
02:48	lazybot	wasamasa: Uh, no. Why would you even ask?
05:22	loke	I have a dilemma
05:23	loke	And I need assistance from someone with more clojure experience than me
05:24	broquaint	loke: Go on ...
05:24	loke	yes, typing :-)
05:25	loke	I have a value, let's call it "foo" with the following structure: {"key0" {:a "a0" :b "b0"} "key1" {:a "a1" :b "b1"}}. I then have a list of the following form: [{:id "key0" :a "some value"} ...]
05:25	loke	I want to create a function that does the following:
05:26	loke	Update "foo" with the content of the list, but only modify values that are actually included (and non-nil), otherwise the old vlues should be preserved
05:26	loke	so the result of the above would be:
05:26	loke	{"key0" {:a "some value" :b "b0"} ...}
05:27	loke	Any new values that are not in "foo" should be added
05:27	loke	My current solution is an incredibly hairy mess of union, remove, conj and reduce
05:28	justin_smith	loke: sounds like you want update-in
05:28	justin_smith	or maybe just assoc-in
05:28	loke	assoc-in? Hmm, never used
05:28	justin_smith	,(assoc-in {:a {:b 1}} [:a :c] 2)
05:28	clojurebot	{:a {:b 1, :c 2}}
05:29	loke	Hmm... I need to think some more on this
05:31	loke	related: Is there a standard way to do "map" on a map (in other words, transform the elements on a map). The best I have come up with is (reduce (fn [z [k v]] (conj z (THE-UPDATE))) {} THE-MAP)
05:32	TEttinger	loke: &(map (fn [[k v]] (str k "," v)) {"a" 1, "b" 2})
05:32	TEttinger	,(map (fn [[k v]] (str k "," v)) {"a" 1, "b" 2})
05:32	clojurebot	("a,1" "b,2")
05:32	loke	That results in a list though, I want the output to still be a map, but transformed
05:33	TEttinger	(doc zipmap)
05:33	clojurebot	"([keys vals]); Returns a map with the keys mapped to the corresponding vals."
05:33	TEttinger	no...
05:33	TEttinger	(doc map-kv)
05:33	clojurebot	Titim gan éirí ort.
05:33	TEttinger	(doc mapkv)
05:33	clojurebot	It's greek to me.
05:33	TEttinger	what was it...
05:33	justin_smith	(doc reduce-kv)
05:33	clojurebot	"([f init coll]); Reduces an associative collection. f should be a function of 3 arguments. Returns the result of applying f to init, the first key and the first value in coll, then applying f to that result and the 2nd key and value, etc. If coll contains no entries, returns init and f is not called. Note that reduce-kv is supported on vectors, where the keys will be the ordinals."
05:34	loke	Sounds very much like what I have. I wonder if the implmenetation is similar
05:35	justin_smith	it's probably similar but faster (using a transducer and/or transients)
05:35	TEttinger	,(into {} (map (fn [[k v]] (str k "," v)) {"a" 1, "b" 2}))
05:35	clojurebot	#error {\n :cause "java.lang.Character cannot be cast to java.util.Map$Entry"\n :via\n [{:type java.lang.ClassCastException\n :message "java.lang.Character cannot be cast to java.util.Map$Entry"\n :at [clojure.lang.ATransientMap conj "ATransientMap.java" 44]}]\n :trace\n [[clojure.lang.ATransientMap conj "ATransientMap.java" 44]\n [clojure.lang.ATransientMap conj "ATransientMap.java" 17]\n [...
05:36	justin_smith	TEttinger: that's silly, you can only create a map out of two element vectors
05:36	TEttinger	right yes I forgot what I was doing
05:36	TEttinger	~ambien dreams
05:36	clojurebot	Pardon?
05:37	TEttinger	clojurebot: ~~~ is the smooth wave calling you to sleep
05:37	clojurebot	Roger.
05:37	TEttinger	~~~~
05:37	clojurebot	~~~ is the smooth wave calling you to sleep
07:40	noncom	does emacs work over ssh in terminal mode ?
07:41	noncom	i try to start it like that, on an ssh session, but all i get is the prompt hanging until i ctrl + C and get back to the bash...
07:42	H4ns	do you have a DISPLAY variable set in your shell?
07:46	noncom	nvm, got it.. somehow it was launching without the -nw key :)
07:47	noncom	but i was thinking it did..
07:47	noncom	emacs is great!
07:47	noncom	the only downside (as i see it) is elisp...
07:48	noncom	but still much much much better that, say JS, within, say GitHub Atom or Adobe Brackets..
07:48	noncom	or python you know where
07:54	dottedmag	noncom: Do you really need emacs over ssh? tramp FTW
07:55	dottedmag	noncom: also with lexical-binding: t elisp is tolerable
07:56	noncom	hmmm, yeah, tramp is a nice option! but it won't make the shell accessible i think..
07:56	algernon	dottedmag: sometimes you run local commands on the remote host that want an editor, an emacs on the remote host is useful then.
07:58	dottedmag	noncom: eshell has some support
07:58	dottedmag	algernon: oh right, pretty much the only case when remote emacs is needed.
07:59	H4ns	dottedmag: what is wrong with using emacs through ssh?
07:59	dottedmag	H4ns: no GUI? Burden of syncing ~/.emacs? Different Emacs versions?
07:59	dottedmag	noncom: http://stackoverflow.com/questions/1346688/ssh-through-emacs-shell/1372805#1372805
08:09	wiruzx	Good evening
08:12	wiruzx	Could anyone please help me to fix this macro to be able to use it in threading(->) macro?
08:12	wiruzx	(defmacro <? [expr]
08:12	wiruzx	`(throw-err (<! ~expr)))
08:13	wiruzx	If I make it function composition, clojure will yell at me because it outside of go block
08:20	wasamasa	a macro without unquoting??
08:20	lazybot	wasamasa: What are you, crazy? Of course not!
08:20	wasamasa	phew, must be me seeing things
08:44	noncom	hah, so, emacs runs over ssh, yes... but with each new charecter i enter, it.. scrolls the screen and destroys the visual image... unusable... ?
08:44	noncom	(currently trying without tramp)
08:45	noncom	yeah, i generally want to replace the need for "nano somefile" with "emacs somefile" over ssh
08:45	H4ns	noncom: you've probably not set up your terminal type correctly
08:45	H4ns	noncom: try "env TERM=vt100 emacs" to see whether that changes anything.
08:46	H4ns	noncom: #emacs may be a more appropriate channel to get help with this, though.
08:46	noncom	yes, #emacs, but they often just ignore questions.. too much buzz goes over there... but i agree, i must better be asking in #emacs..
08:47	H4ns	noncom: no worries.
08:47	H4ns	noncom: my experience with #emacs has also not been too good.
08:47	noncom	heh, term=vt100 works... sort of. it looks better, but still in some situations it cripples the visual.. nano works quite well though!
08:48	H4ns	noncom: then your TERM environment variable does not match what your terminal emulator actually supports.
08:48	noncom	frankly, i am not even hoping to get this resolved.. just asking what my odds are..
08:48	noncom	probably. i will research into this subject and read the manuals
09:39	hellofunk	if you repeat your question about three or four times in #emacs you will eventually get a good answer
09:39	hellofunk	not the shining example of good help, but works eventually
09:46	kwladyka	How to write this in most readable way? https://www.refheap.com/106526
09:47	kwladyka	i just want check if two conditions are true, but i want check second condition only if (= m n)
09:47	kwladyka	i can write this with "if" but i guess there is shorter way.
09:53	TMA	kwladyka: personally I would (defn solution-checker-rotate* [m n solutions] (or (not (= m n)) (solution-checker-rotate m n solutions)))
09:53	TMA	or just inline the (or)
09:54	schmir	kwladyka: (and (= m n) (solution-checker-rotate ...))
09:57	kwladyka	tma shmir thx
10:22	mmeix	What is the best method to find all possible combinations of n elements?
10:25	oddcully	clojure.math.combinatorics/permutations maybe?
10:25	mmeix	must work in clojurescript
10:26	zerokarmaleft	mmeix: I don't think there's any reason those implementations wouldn't work in cljs
10:27	mmeix	ok, will try
10:27	mmeix	thnx
10:32	divya	Hello?
10:46	mmeix	hello
11:07	hellofunk	i am seeking the most elegant way to return the first positive number from a vector like [nil 0 :a 5 6 0]. i get (->> a (filter number?) (filter pos?) first) but seems rather verbose
11:11	dstockton	im trying to learn from the datascript source https://github.com/tonsky/datascript/blob/master/src/datascript/core.cljc#L341
11:11	dstockton	can anyone explain the rationale behind defrecord-updatable, rather than having a normal record with mutable refs
11:14	dstockton	i think the updatable bit is confusing me, its not really updating
11:21	dstockton	its basically a way to defrecord on-the-fly?
11:22	jsabeaudry	When I rename-buffer my cider repl buffer, it does not work anymore, what is the proper way?
11:27	aztak	bazinga all! Switching to the LRU window (like in vim, C-w C-p) - how do I do that in Spacemacs?
11:27	aztak	Like C-6 for buffers.
11:31	aztak	ouch - sorry for that - obviously wrong channel!
11:31	aztak	I'll ask a Clojure question in the Spacemacs channel to compensate!
11:32	diyfupeco	aztak: Are you a long time vimer who switched to spacemacs?
11:32	aztak	diyfupeco: yupp, that's correct :)
11:33	diyfupeco	aztak: I thought about trying it, where do you see the advantages?
11:34	aztak	diyfupeco: it's a bit like comparing apples and oranges.. I get almost all of the text-editing goodness in VIM and I get access to all the Emacs ecosystem.
11:35	aztak	org-mode is the feature that pushed me over the edge - it's a killer feature.
11:35	diyfupeco	Hm, thanks.
11:35	diyfupeco	I will try it.
11:46	scriptor	diyfupeco: I've also picked up emacs+evil-mode for clojure stuff
11:47	scriptor	it's not too bad, I'll still keep using just vim for non-clojure work
11:50	diyfupeco	I am so afraid because it totally breaks my workflow. :D
11:52	scriptor	diyfupeco: what specifically about your workflow are you worried about?
11:56	diyfupeco	scriptor: My VIM is configured for quick actions with space as the leader key. Also ctrl+p and splits. Next thing is about connecting to the repl and execute something in it. And those little things like signify, multiple cursors and sayonara (all plugins).
11:57	diyfupeco	Ah yeah, and undotree
11:57	scriptor	evil comes with support for splits, at the very least
11:58	scriptor	and for the quick actions stuff, you can learn a minimum of elisp to recreate some of that
11:59	vaitel	I know that there is a multiple cursors plugin on melpa too.,
11:59	diyfupeco	Hm, ok. How about undo[dir\|levels]?
12:00	diyfupeco	vaitel: I'd be suprised if emacs wouldn't have one to be honest.
12:01	vaitel	diyfupeco: http://www.emacswiki.org/emacs/UndoTree
12:02	diyfupeco	vaitel: cool :)
12:02	diyfupeco	Well, ok, I promise to try it. :D
12:02	wasamasa	emacs' undo system is sort of meh
12:02	diyfupeco	But please don't burn me when I try to recreate my vim expirience at first. :D
12:02	vaitel	I use evil-mode, and undo-tree is installed as a dependency.
12:03	wasamasa	I've had used undo-tree with persistency for some time and found out that the saved history did get truncated after too huge edits
12:03	vaitel	diyfupeco: that's pretty much exactly what I did when I first started with emacs.
12:05	diyfupeco	I think I'll switch to another channel now with my questions. :D
12:07	wasamasa	like, #emacs?
12:08	diyfupeco	wasamasa: #spacemacs on gitter.im is more suited at the moment I think. I joined #emacs anyway.
12:10	wasamasa	right
12:10	the_frey_	multiple cursors on emacs is okay, it's not quite as good as vim
12:10	aztak	diyfupeco: also check irc.gitter.im
12:10	the_frey_	and imho both are worse than sublime text
12:10	the_frey_	*for multiple cursors
12:11	the_frey_	the st implementation is just slick
12:12	diyfupeco	Let's build submacim! :P
12:13	diyfupeco	aztak: Thanks for the hint. :)
12:34	binjured	does anybody know how to get cljsbuild to build some cljc files from a dependency jar? i have a shared library dependency that contains combined sources (cljc). i can add it as a dependency and require from the jar as clj, but cljsbuild doesn't know about the cljc in the jar.
12:52	seangrov`	Has anyone tried doing xhr-based file uploads to compojure routes before? I'm not sure what to do with the HttpInput body
13:00	dasik`	Does it make sense to use JSON Web Encryption (JWE) tokens when I'm writing a basic CRUD webapp? All the writing I've found about token authentication talks about single-page applications.
13:17	justin_smith	wasamasa: "emacs undo system is kind of meh" -- have you tried undo-tree?
13:17	justin_smith	oh, never mind, /me goes back to reading
13:17	wasamasa	justin_smith: it builds upon the built-in undo system
13:18	wasamasa	justin_smith: so, while it's really handy to have a tree-style redo, I've run into a really weird bug or two with it and persistency enabled
13:18	csd_	If t represents a java object, and I have a coll of [ts], how can i map .setter to [ts]? I'm having trouble using (map #(.setter %1 %2) ts [vals])
13:18	justin_smith	sure. But aren't your concerns addressed by upping the amount of history saved? like for similar reasons I always expand the size of my kill ring
13:18	wasamasa	at some point I did just disable it when I got "Undo canary detected" messages all over the place
13:18	justin_smith	wasamasa: interesting, you must be using it much more heavily than I ever do
13:19	wasamasa	justin_smith: well, I just have an eye for spotting bugs, that's all
13:19	justin_smith	binjured: which version of clojure is cljsbuild using/
13:21	justin_smith	binjured: with clojure 1.7 I have had no issue getting code from cljc files in libs
13:43	scriptor	have any evil users here been able to use the eval-buffer keybinding with cider?
13:44	justin_smith	scriptor: I don't use cider, but I think your best bet is to rebind the command to something that works better with evil
13:45	scriptor	hmm, I was trying to rebind it on evil's side, but that might be best
13:46	justin_smith	scriptor: that's what I mean. Find out the actual command that keybinding would run, and bind some other key combo to that command
13:46	justin_smith	which is why I hate it when people document the keypress but not the specific command to run - the command is universal, the keypress is particular and very likely to not work on any given person's emacs setup
13:49	scriptor	agreed, had to guess where the actual binding is set in the sourc
13:49	scriptor	didn't take long, but still
14:01	wasamasa	so you still didn't run F1 k C-c C-k?
14:01	justin_smith	wasamasa: if the keybinding is broken, asking what a key is bound to isn't going to help much
14:02	justin_smith	something already messed up the binding
14:02	wasamasa	yes and you'd want to know what
14:02	justin_smith	wasamasa: evil mode
14:02	justin_smith	he already knew that
14:02	wasamasa	I find this somewhat hard to believe considering evil doesn't bind anything to C-c or C-x
14:02	wasamasa	which is done on purpose
14:03	wasamasa	in vim C-x would be bound to either the increment or decrement command (evil doesn't ship with any of these, it's an extra package you need to install and bind yourself), C-c would be bound to a quitting command, but isn't here
14:06	wasamasa	so I'm curious what would be going on here
14:52	edw	Ping
14:52	Bronsa	edw: hi
14:53	edw	Bronsa: Hey. Slow day…
14:54	Bronsa	edw: lot of traffic has moved from irc to the slack channel it seems
14:54	edw	Whu?
14:54	edw	Clojure.org?
14:54	Bronsa	edw: https://clojurians.slack.com/
14:55	edw	I was just thinking, "I wish i could connect to Freenode via the Slack (Mac\|iOS) app…"
14:57	hiredman	really?
14:58	hiredman	that is too bad
15:01	lemonodor	“To start using Slack, you'll need to be invited by your team administrator” is it not public?
15:05	Bronsa	lemonodor: http://clojurians.net/ to get an invitation
15:05	Bronsa	hiredman: yeah :( it's not as bad as it could be though, slack has an irc gateway
15:06	freeman42x	Bronsa, irc gateway?
15:06	Bronsa	freeman42x: https://slack.zendesk.com/hc/en-us/articles/201727913-Connecting-to-Slack-over-IRC-and-XMPP
15:11	lemonodor	Bronsa: thanks
15:14	Frozenlock	IRC master race
15:14	Frozenlock	Slack dirty peasants
15:14	freeman42x	Frozenlock, i for one welcome our new slack overlords
15:15	oddcully	s/overlord/team administrator/
15:29	zphds	Guys, why is the PSQLException in line 5 in this gist not getting caught? https://gist.github.com/sudharsh/6801838e92bc0fc0a985
15:29	zphds	It's late and am scratching my head
15:30	zphds	evaluating the map form on the repl throws a PSQLException
15:36	amalloy	zphds: having not looked at the paste, i'll bet you a million dollars it's because of lazy sequences
15:36	amalloy	and, indeed, it is
15:36	amalloy	~map
15:36	clojurebot	map is laziness
15:37	zphds	amalloy: but why I don't I get lazy-seq when I do it on the repl?
15:38	zphds	s/I don't/don't/
15:38	kwladyka	i have map {[1 1] :king [1 3] :king [1 2] :rook} and i want change it into {{[1 1] :king [1 3] :king [1 2] :rook}{[2 1] :king [2 3] :king [2 2] :rook}{[3 1] :king [3 3] :king [3 2] :rook}} <- the number are just example. I want do some magic operations on keys and change them. How to do this in most elegant way?
15:39	amalloy	zphds: your function immediately returns a lazy sequence, realizing no elements of it. then in the repl, you try to evaluate an element, throwing an exception, and there's no handler installed at that point
15:39	kwladyka	something like (do-magic-algorithm {[1 1] :king [1 3] :king [3 2] :rook}) to produce me that
15:39	zphds	amalloy: is there an implicit doall ?
15:39	zphds	ah gotcha
15:39	amalloy	no? i don't understand this question
15:40	ToxicFrog	kwladyka: your "after" example isn't even a valid map, so I have no idea what you actually want here.
15:40	zphds	amalloy: I could do a (doall (map...))
15:40	zphds	and realize the lazy-seq
15:40	kwladyka	ToxicFrog, It should be #{}
15:40	zphds	amalloy: dorun should be fine, since I can just throw away the results
15:41	kwladyka	{[1 1] :king [1 3] :king [3 2] :rook} into #{{[1 1] :king [1 3] :king [1 2] :rook}{[2 1] :king [2 3] :king [2 2] :rook}{[3 1] :king [3 3] :king [3 2] :rook}}
15:42	amalloy	kwladyka: nobody can guess what your algorithm is here. how are the outputs related to the inputs? it's like asking "i have the numbers 4, 9, and 17, and i need to get out 491. what function should i use?"
15:42	kwladyka	amalloy, algorithm it is not important, i just want know which function i can use to produce from one map more maps with different keys
15:43	zphds	amalloy: cool, plugging in a dorun is what I needed. Thanks!
15:44	zphds	not worried about the size since the input is going to be less anway. So dorun should be good.
15:46	kwladyka	to be more precise, example input and output https://www.refheap.com/106532
15:47	kwladyka	amalloy, ^
16:30	cryptack	I need to integrate with Spring and I’d like to define Spring beans, I’m wondering if anyone knows a way to do this in clojure (it requires Java annotations ontop of a class, I couldn’t find any info online)
16:33	cryptack	I found something that said you can annotate with deftype, but I don’t know if that corresponds to clojure metadata or Java class annotations
16:41	kwladyka	how change ([1 1] [1 3] [3 2]) into for example ([1 1+4] [1 3+4] [3 2+4]) ?
16:42	justin_smith	what is "1+4"
16:43	kwladyka	5 :)
16:44	lemonodor	kwladyka: you could look at reduce-kv
16:44	justin_smith	,(map (fn [[a b]] [a (+ b 4)]) '([1 1] [1 3] [3 2]))
16:44	scriptor	kwladyka: you'll want to map over the list which will let you iterate over the pairs
16:44	clojurebot	([1 5] [1 7] [3 6])
16:45	justin_smith	lemonodor: oh, reduce-kv would work for that structure wouldn't it...
16:46	justin_smith	,(reduce-kv (fn [acc k v] (conj acc [k (+ v 4)])) [] '([1 1] [1 3] [3 2]))
16:46	clojurebot	#error {\n :cause "No implementation of method: :kv-reduce of protocol: #'clojure.core.protocols/IKVReduce found for class: clojure.lang.PersistentList"\n :via\n [{:type java.lang.IllegalArgumentException\n :message "No implementation of method: :kv-reduce of protocol: #'clojure.core.protocols/IKVReduce found for class: clojure.lang.PersistentList"\n :at [clojure.core$_cache_protocol_fn invoke...
16:46	justin_smith	no, reduce-kv won't work for that actually
16:46	justin_smith	(if that was literally the datastructure)
16:47	scriptor	map seems to make more idiomatic sense in this case, too
16:47	scriptor	since it's just a one-to-one...mapping
16:47	Seylerius	What's the best way to name a new library one's planning to publish? Should it be at one's own domain, if one has such a domain? If I own seriouslyseylerius.com, should it be "com.seriouslyseylerius/astronomy" if I'm making an astronomy library (for calculating full moon dates and whatnot)? And what sort of lein command should I use for declaring it?
16:48	justin_smith	Seylerius: lein new foo com.seyleruis/astronomy
16:48	justin_smith	where foo is your template
16:48	justin_smith	if the project is already there, you have to edit a bunch of stuff by hand
16:48	lemonodor	i do prefer the reverse DNS style names, but lots of people just choose a top-level unique name, like “astronomie” or something.
16:49	justin_smith	yeah, I think that's sloppy / bad form though
16:50	Seylerius	Okay, so `lein new com.seriouslyseylerius/astronomy`, then push the thing to github as `seylerius/astronomy` on my profile?
16:50	Seylerius	I need to get around to changing my github name from emhs to seylerius, since I'm using that for everything these days...
16:51	lemonodor	justin_smith i tend to agree, but i don’t think the community in general necessarily feels the same way. e.g. midje, clj-time, lein-gorilla, gloss, seesaw
16:51	kwladyka	hmm maybe reduce-kv is even better... on the end i want do https://www.refheap.com/106532
16:52	kwladyka	for now i did https://www.refheap.com/106534
16:52	kwladyka	and i wanted transform positions in zipmap
16:52	justin_smith	kwladyka: you need a data-structure that implements the IKVReduce protocol, and you have duplicate "keys"
16:53	kwladyka	justin_smith, i dont have.
16:54	kwladyka	justin_smith, so.... my solution with zipmap is a good way or should i use something like reduce-kv?
16:55	kwladyka	or any other solution
16:55	oddcully	isn't (map key) the same as (keys) ?
16:55	oddcully	same for val/vals?
16:55	kwladyka	oddcully, no
16:55	amalloy	yes
16:56	kwladyka	no, it would throw exception
16:56	oddcully	yeahyeah... (map key) is a transducer ;P
16:56	amalloy	no
16:56	amalloy	oh, you're not calling it on anything?
16:56	amalloy	no, you are. (map key x) is the same as (keys x)
16:57	amalloy	that is the implementation of (keys x)
16:57	oddcully	that's what i meant but lazily excluded
16:57	kwladyka	oh i didn't see "s" on the end of this word...
16:57	kwladyka	sorry
16:57	kwladyka	but good to know i can write it shorter :)
16:58	oddcully	and isn't then (zipmap (keys x) (vals x)) just randomizing your map?
16:58	thesaskwatch	I'm trying to test a function using midje and I would like to verify content that it printlns. Any idea how to do that?
16:59	kwladyka	so... do you think my solution with zimap to achive keys transformation for example from ([1 1] [1 3] [3 2]) into ([1 1+4] [1 3+4] [3 2+4]) is good or do you see better solution?
16:59	lemonodor	justin_smith: compojure, cascalog, clj-http, enlive, hiccup, instaparse, every lein plugin, ring, secretary (sorry, i went to the trouble to find popular packages i’ve used that don’t use the reverse dns naming scheme)
16:59	kwladyka	oddcully, it do nothing for now... i have to add something to (keys x) to transform keys
17:01	kwladyka	oddcully, and i know keys and vals give values in order?
17:07	kwladyka	if somebody is interested in this is my full worked solution https://www.refheap.com/106535
17:14	zerokarmaleft	having a weird compojure issue here...prod env is basically nginx reverse proxied to a clojure app with a couple endpoints. routes match when hitting the app server directly, routes match when hitting a dev setup mimicking the nginx setup, GET routes match when hitting the prod setup, POST routes mysteriously fail to match.
17:14	kwladyka	thank you for discussion and goodnight :)
17:15	oddcully	kwladyka: yeah sorry, i actually don't know what garanties clojure map holds in that case. i defensively assumed unordered access. but if the seq of elements is the same, then there is no randomization
17:15	zerokarmaleft	the headers don't appear mangled in any way, and the URI logged at nginx and at the app is correctly formed
17:15	zerokarmaleft	any ideas on what I could check next?
17:54	junger	howdie everyone
17:54	junger	is someone familiar with om-bootstrap ?
17:54	junger	I'm evaluating using it, and I am bumbing into a problem using alerts
17:56	oddcully	junger: just fyi there is also #clojurescript
18:00	junger	@thanks, will check it out
18:19	Seylerius	What's the recommended way for an app using one's library to set a library-wide setting, like API usage level?
18:20	justin_smith	Seylerius: would two parts of one app ever have separate configs for the same lib?
18:21	Seylerius	I'm building a rate limiter into an API lib I'm putting together (refactoring all the Wunderground API stuff I'm using in my weather-generator app to a lib of its own), and I want people to be able to specify which API level they've purchased (Developer, Drizzle, Shower, Downpour) and have it automatically cap their usage at the required rate. So it's unlikely they'd have separate configs. It's a per-API-key setting (I'd probably also
18:21	Seylerius	use this to allow them to set the API key, too)
18:23	Seylerius	justin_smith: So, very unlikely that they'd have multiple configs per app.
18:23	Seylerius	Unless they're using two different API keys in the app, which have different usage levels.
18:23	Seylerius	But what's more likely is there'd be an API key in the dev version and a separate API key in the production version.
18:24	justin_smith	Seylerius: the reason I ask, is a common thing is a top level atom, but that makes using different API keys impossible
18:24	justin_smith	so is it OK to make it not possible at all, or is it worth it to do something slightly less simple so that multiple keys is occasionally an option?
18:38	lodin_	Is there a term for objects that require cleanup? Like objects that should be closed, etc. First thing that came to mind was "stateful" but atoms are also stateful, so that's not quite right.
18:38	Seylerius	justin_smith: I can think of exactly /one/ reason to use multiple API keys in an app: load-balancing requests across different keys.
18:38	Seylerius	But that's probably a violation of the ToS.
18:39	Seylerius	Hell, I'll bug Gundeep and double-check if it is.
18:39	Seylerius	'Cause if it is, disallowing it in my lib will probably make the wunderground people like me better.
18:47	Seylerius	justin_smith: Baring an update from Mr Hora to the contrary, I can't think of a good reason to use multiple API keys, so I'll go with the top-level atom approach. Got a decent link on the basics of it?
18:47	justin_smith	Seylerius: these issues are fresh in my mind because I am setting up our timbre config in an internal project right now, and sometimes I really wish timbre did not have a single global config for all options
18:48	justin_smith	Seylerius: it's pretty straightforward to implement (def config (atom {:credentials nil}))
18:48	justin_smith	then maybe provide a convenience function like set-credentials! or something that mutates the config
18:49	Seylerius	justin_smith: Perfect, thanks.
18:49	Seylerius	justin_smith: Can you think of a good reason for people to need multiple API keys for a weather API?
18:50	justin_smith	Seylerius: if your app had multiple users, but only had to check the weather once and could share that data between the users in one area
18:50	justin_smith	which is probably a weird use case
18:52	Seylerius	justin_smith: Yeah, that wouldn't be likely with Wunderground unless individual users were adding their API keys to the app, which the API key generating interface seems not to be optimized for.
18:54	Seylerius	justin_smith: Confirmation from Gundeep: load-balancing is against ToS.
18:55	justin_smith	then you're probably all set using an atom
18:57	Seylerius	Thanks
18:57	Seylerius	(inc justin_smith)
18:57	lazybot	⇒ 276
18:57	Seylerius	(Why do you people rock so hard?)
19:17	elvis453561	How do you use CSS selectors with garden for Ronald Mcdonald's sake
19:17	elvis453561	?
19:18	oddcully	elvis453561: just fyi there is also #clojurescript
19:18	elvis453561	[:input (not [...]) {...}] render as: input, :not [...]
19:19	elvis453561	Yeah I could try it but: Usually it's dead compared to here and I'm using garden on the JVM so...
19:21	oddcully	just mentioning it... feel free to do whatever you thing is right
19:56	devn	anyone here know of an example of using core.async pipeline?
20:13	tmtwd	hello, I was trying out yesql for fun, and put it in the project.clj file deps,and called lein deps. Then today I installed posgresql for the first time but it would work. Could lein have done something to mess up my path or something?
21:05	Shayanjm	arrdem: I didn't realize you worked @ Factual
21:05	Shayanjm	we just started using factual @ work
21:09	arrdem	Shayanjm: yeah I'm here for the summer giving amalloy and everyone else a headache IRL rather than just over IRC
21:09	Shayanjm	sweet. We just turned the key on our lead gen engine, so I think we're giving factual a go
21:10	arrdem	cool!
21:10	Shayanjm	Do you guys already do google place scraping btw?
21:10	arrdem	I don't know and probably couldn't say
21:10	Shayanjm	gotcha
21:43	rs0	lodin_: "resources," I suppose?
21:43	rs0	lodin_: in the sense of "automatic resource management"/"try-with-resources"
22:05	Seylerius	Is some the best way to see if a given keyword is a member of a specific collection? I've got a map called rates, with a map as each value, and the argument provided to this function needs to be one of the keys in rates.
22:06	Seylerius	Or contains? maybe?
22:06	justin_smith	Seylerius: contains? might be what you are looking for
22:07	justin_smith	Seylerius: see also find, which returns nil, or the key and value as a vector
22:07	justin_smith	(doc find)
22:07	clojurebot	"([map key]); Returns the map entry for key, or nil if key not present."
22:37	gcganley	are there any clojure stickers for something like the back of a laptop?
22:39	scriptor	gcganley: http://clojure.org/swag
23:12	sturner	Anyone have an recommendations for handling units/measurements? Frinj looks pretty interesting. I'm a clojure newbie... I've used http://www.squants.com/ before which I found to be powerful but I'm wondering how I might convey values with unit across the network to other systems in a similar manner in clojure. Transmit maybe?
23:17	tomjack	hmm "Tries to combine Frink's fluent calculation style with idiomatic Clojure"
23:18	tomjack	does it succeed?
23:18	tomjack	(frinj)
23:28	Raynes	Does it?
23:28	Raynes	You tell me, sir.
23:28	Raynes	For I am not the judge.
23:30	Raynes	Well, at first glance, there are some pretty horrifying things going on.
23:30	Raynes	Like override-operators!
23:30	Raynes	I'm kinda shivering a bit over that one.
23:32	sturner	Yeah... I'm very much a clojure beginner so I can't comment. Frink is an interesting language in and of itself but the library implementing it seems to only implement a parse().
23:43	amalloy	frinj is just super old, isn't it?
