10:41	gfredericks	does anybody know of any tools for reducing the redundancy between docstrings and READMEs?
10:44	TimMc	gzip, I think
10:45	dumptruckman	hello
10:45	gfredericks	TimMc: :P
10:48	dumptruckman	looking for a hint with this koan... "One function can beget another" (= 9 (((fn [] ___)) 4 5))
10:49	justin_smith	dumptruckman: that function needs to return a function that takes 4, 5 and returns 9
10:49	justin_smith	the ___ are the position for a value to be returned
10:50	justin_smith	,(((fn [] str)) "hello" ", " "world")
10:50	dumptruckman	oooh
10:50	clojurebot	"hello, world"
10:50	dumptruckman	that's why there are 2 sets of paren
10:50	justin_smith	right
10:52	dumptruckman	well
10:52	dumptruckman	i thought i had tried to do what you said
10:52	dumptruckman	and it didn't work
10:52	gfredericks	,(((fn [] (fn [] (fn [] print-str)))) 'hello 'more 'worlds)
10:52	clojurebot	#error{:cause "Wrong number of args (3) passed to: sandbox/eval51/fn--52/fn--53", :via [{:type clojure.lang.ArityException, :message "Wrong number of args (3) passed to: sandbox/eval51/fn--52/fn--53", :at [clojure.lang.AFn throwArity "AFn.java" 429]}], :trace [[clojure.lang.AFn throwArity "AFn.java" 429] [clojure.lang.AFn invoke "AFn.java" 40] [sandbox$eval51 invoke "NO_SOURCE_FILE" 0] [clojure.la...
10:52	dumptruckman	but trying it again it worked
10:52	justin_smith	gfredericks: I think you needed more parens
10:53	gfredericks	as usual
10:53	gfredericks	,((((fn [] (fn [] (fn [] print-str))))) 'hello 'more 'worlds)
10:53	clojurebot	#error{:cause "Wrong number of args (3) passed to: sandbox/eval81/fn--82/fn--83/fn--84", :via [{:type clojure.lang.ArityException, :message "Wrong number of args (3) passed to: sandbox/eval81/fn--82/fn--83/fn--84", :at [clojure.lang.AFn throwArity "AFn.java" 429]}], :trace [[clojure.lang.AFn throwArity "AFn.java" 429] [clojure.lang.AFn invoke "AFn.java" 40] [sandbox$eval81 invoke "NO_SOURCE_FILE" ...
10:53	luoluoluo	(println "hello")
10:53	gfredericks	I give up
10:53	dumptruckman	,(((fn [] (fn [] (fn [] (print-str))))) 'hello 'more 'worlds)
10:53	clojurebot	#error{:cause "Wrong number of args (3) passed to: sandbox/eval111/fn--112/fn--113", :via [{:type clojure.lang.ArityException, :message "Wrong number of args (3) passed to: sandbox/eval111/fn--112/fn--113", :at [clojure.lang.AFn throwArity "AFn.java" 429]}], :trace [[clojure.lang.AFn throwArity "AFn.java" 429] [clojure.lang.AFn invoke "AFn.java" 40] [sandbox$eval111 invoke "NO_SOURCE_FILE" 0] [clo...
10:53	luoluoluo	,(print "hello")
10:53	clojurebot	hello
10:53	justin_smith	,(((((fn [] (fn [] (fn [] print-str)))))) 'hello 'more 'worlds)
10:53	clojurebot	"hello more worlds"
10:53	dumptruckman	i was about to try that next
10:53	justin_smith	gfredericks: classic, off by one
10:54	gfredericks	I'm just the idea guy, I don't mess with parens.
10:56	dumptruckman	wait...
10:56	dumptruckman	this still isn't working
10:56	dumptruckman	(= 9 (((fn [] #(* %1 %2))) 4 5))
10:56	gfredericks	have you checked what the right bit evals to?
10:56	justin_smith	dumptruckman: ##(* 4 5) ; last I checked this was not 9
10:56	lazybot	⇒ 20
10:56	dumptruckman	doh
10:57	gfredericks	,(Math/exp 4 5)
10:57	clojurebot	#error{:cause "No matching method: exp", :via [{:type clojure.lang.Compiler$CompilerException, :message "java.lang.IllegalArgumentException: No matching method: exp, compiling:(NO_SOURCE_PATH:0:0)", :at [clojure.lang.Compiler analyzeSeq "Compiler.java" 6740]} {:type java.lang.IllegalArgumentException, :message "No matching method: exp", :at [clojure.lang.Compiler$StaticMethodExpr <init> "Compiler....
10:57	justin_smith	dumptruckman: also #(* %1 %2) is * (given you are guaranteed two args)
10:57	justin_smith	,(Math/exp 4.0)
10:57	clojurebot	54.598150033144236
10:57	gfredericks	aw shucks
10:57	justin_smith	,(Math/pow 4.0 5.0)
10:57	clojurebot	1024.0
10:57	justin_smith	hehe
10:58	justin_smith	or arities
10:58	gfredericks	yeah any of those
11:02	dumptruckman	can't seem to figure this one out either (= 25 (___ (fn [n] (* n n))))
11:02	dumptruckman	my guess was (fn [f] (f))
11:02	justin_smith	I think there needs to be a 5 somewhere
11:03	dumptruckman	oh right
11:03	dumptruckman	that would make sense >.>
11:03	dumptruckman	i need more coffee
11:04	dumptruckman	anyone got any resources for helping to think functionally
11:05	dumptruckman	having trouble changing my thinking away from the use of mutable state
11:05	justin_smith	I have heard of some koans...
11:05	justin_smith	:)
11:05	dumptruckman	i mean on a more theoretical level
11:06	justin_smith	dumptruckman: the general principle is actually pretty simple. Anything that needs to "change" must become the argument to a new function call or recursion
11:06	justin_smith	so that in that new scope the new value replaces the previous (though the original has not mutated)
11:07	dumptruckman	i mean, i get the principle.. i just feel like i need to read/watch something to help really retrain my innate thinking
11:07	dumptruckman	of course maybe i'm just wanting to procrastinate
11:08	justin_smith	dumptruckman: have you used loop/recur?
11:08	dumptruckman	;)
11:08	dumptruckman	no
11:08	justin_smith	,(loop [x 0 y 0] (if (> x 100) x (recur (+ x y) (inc y))))
11:08	clojurebot	105
11:09	geirby	morning
11:10	justin_smith	dumptruckman: it should be clear how the args to that recur are effectively modifying x and y
11:10	justin_smith	but it's not a mutation, it's a new binding that does not alter the previous value
11:10	justin_smith	you could try it in your repl, with some printing added
11:10	geirby	who can tell where ->RedBlackTree come from here http://bit.ly/1GiiYnw ? Is it some feature of deftype I'm not aware of?
11:10	gfredericks	,(deftype Heyo [])
11:10	clojurebot	sandbox.Heyo
11:10	gfredericks	,->Heyo
11:10	clojurebot	#object[sandbox$eval49$__GT_Heyo__51 0x752f5f2a "sandbox$eval49$__GT_Heyo__51@752f5f2a"]
11:10	gfredericks	,(doc ->Heyo)
11:10	clojurebot	"([]); Positional factory function for class sandbox.Heyo."
11:10	gfredericks	geirby: yep.
11:12	TimMc	gfredericks: Here is a ridiculous thing I made: https://github.com/timmc/arrpl
11:12	dumptruckman	so
11:12	gfredericks	"Hmm, I seem to have made a ridiculous thing. Somebody must tell gfredericks about it!"
11:12	TimMc	exactly
11:12	TimMc	to be fair, I'm telling everyone
11:12	dumptruckman	recur just changes the values and starts at the beginning of the loop?
11:13	TimMc	...but especially you. PRs welcome. :-P
11:13	justin_smith	dumptruckman: it binds new values, nothing truly changed
11:13	geirby	gfredericks: thanks.
11:13	justin_smith	dumptruckman: but yes, that's the idea
11:13	dumptruckman	so
11:14	dumptruckman	each arg in recur binds to the respective param in loop?
11:14	gfredericks	TimMc: the idea is to coopt existing copyright statements?
11:14	justin_smith	dumptruckman: exactly
11:15	TimMc	gfredericks: Yeah!
11:15	justin_smith	dumptruckman: also, for things that are not a loop, but just an update, you can use let and binding / shadowing ##(let [a 1 b (inc a) c (+ a b) c (inc c)] c)
11:15	lazybot	⇒ 4
11:15	TimMc	I mean... no! It is to explain what all those silly "all rights reserved" statements mean.
11:15	justin_smith	dumptruckman: not that the portion "c (inc c)" does not mutate c, it shadows it with a binding derived from the old one
11:15	TimMc	this is the license those were referring to all along
11:15	justin_smith	*note
11:16	luxbock	dumptruckman: I just finished reading The Little Schemer and I thought it was great
11:16	gfredericks	TimMc: oh I see but now also you are personally famous
11:16	TimMc	as the author of that heavily used license?
11:16	TimMc	I guess so!
11:16	gfredericks	congratulations
11:17	gfredericks	#lifehack
11:17	luxbock	now I get to dive into The Reasoned Schemer next, core.logic here I come
11:19	TimMc	gfredericks: This joke is falling surprisingly flat. Maybe it will be funnier once there's a lawsuit. Lawsuits always make things funny.
11:19	gfredericks	TimMc: I think it's because I'm not a lawyer enough so it doesn't connect with me at a low enough level
11:20	dumptruckman	thanks luxbock
11:25	Shayanjm	If anyone happens to need a hexagonal circle packing implementation : https://github.com/AbleEng/hexpacker <shameless self plug>
11:25	Shayanjm	I also would love some code critiques. Still trying to learn how to write things more clojure-y
11:28	TimMc	gfredericks: Well, it is of course unenforceable, but I really like the ambiguity of the license's own copyright statement.
11:29	TimMc	Also, I'm playing with the notion of "what does it mean to license something". Note how the GPL says you have to include the actual text, but some licenses say you can just link to them.
11:29	TimMc	and I think with some you can just say "available under such and such a license".
11:30	justin_smith	the misunderstandings are numerous
11:31	justin_smith	see for example people that make you click through gpl as if it were a eula (it isn't, it's a redistribution license)
11:38	gfredericks	the numerous misunderstandings are why I don't lawyer very much
11:48	kwladyka	http://www.purelyfunctional.tv/ - is it worth to pay? Somebody watched this?
11:49	kwladyka	or mayby you can recommend somethign more?
11:53	TimMc	gfredericks: that sounds like a good law-er
11:55	gfredericks	TimMc: no beating around the bush
12:42	saik0	Shayanjm: neat. you could eliminate the post-dedup operation by removing the circles on one of the edges
12:51	sveri	quick vote: multimethods or protocols?
12:51	sveri	for a storage abstraction
12:51	justin_smith	sveri: a protocol
12:52	sveri	seems like the protocol wins 1:0 :D
12:52	sveri	justin_smith: any reasons you prefer the protocol?
12:53	justin_smith	sveri: because it abstracts over multiple operations, and dispatches on type
12:53	justin_smith	both of these describe the storage abstraction scenario
12:53	justin_smith	(at the very least you hve put and get)
12:53	sveri	ah, right, multiple operations, so obvious, havn't thought of that, but yea
12:54	justin_smith	and you would have no reason to use any dispatch other than type
12:54	sveri	(inc justin_smith)
12:54	lazybot	⇒ 245
12:54	justin_smith	which means multimethods provide one detriment, and no benefits
12:56	sveri	thank you very much
13:00	ane	using Foo. requires me to import that class, how can i make Foo visible for using it in ->Foo?
13:00	justin_smith	ane: ->Foo does not require import, it only needs require or use
13:01	ane	so to make Foo visible from namespace xyz, what's the way? adding [xyz :refer [Foo]] to require?
13:02	justin_smith	you don't need Foo to be visible, you need ->Foo
13:02	justin_smith	Foo is not a thing you can require, it's a class
13:02	justin_smith	->Foo is a function, something you can require
13:03	ane	oh yeah
13:03	ane	derp
13:06	justin_smith	the whole namespace/var vs. package/class thing is a little weird - less simple than many things in clojure
13:07	ane	i agree. it's a bit confusing, but less so than in other languages
13:08	ane	what are the practical differences between Foo. and ->Foo?
13:08	justin_smith	ane: ->Foo is first class, and can be accessed the same way you would any other var in the namespace
13:09	justin_smith	while Foo. is actually a reader macro expanding to (new Foo)
13:09	justin_smith	and needs import, or fully qualified package name, to access it
13:09	justin_smith	and cannot be used first class
13:41	gfredericks	also cannot be tricked out in the same way as vars
14:29	Lewix	HI guys
14:29	Lewix	https://gist.github.com/6ewis/48968c8d338a1e10424a
14:30	Lewix	I don't understand this piece of code - I know what the output is but i find it difficult to follow the logic
14:30	Lewix	recursion is a pain in the arse
14:31	gfredericks	so is nonstandard indentation :(
14:32	gfredericks	looks like it just maps over the vector producing an output vector
14:33	gfredericks	it uses the first arg to keep track of the stuff it has yet to do, and the second arg to accumulate the output
14:43	Lewix	gfredericks: is it obvious to you cause it dont see it
14:43	Lewix	gfredericks: if it's empty it shows out which is []
14:44	Lewix	the first time around* - if it's not empty it recall itself with two arguments?
14:45	gfredericks	yeah, it's moving things from the first arg to the second
14:46	gfredericks	the mechanisms are first, rest, and conj
15:09	Poky	hey sveri, how's the typed stuff going?
15:12	saik0	how does lighttable display lazy seqs?
15:13	gfredericks	not sure how lighttable does it, but there's a print-length var or something that lets you automatically abridge things
15:16	sveri	Poky: hey there, I got it going, but after adding a lot of functions I did not keep them up to date, however, I finished the first release of closp-crud, the plugin that the typ things were for :-) And how does the scala stuff do for you?
15:20	Poky	nice. I see you're going for that github streak ;)
15:20	Poky	I'm almost done with scala.. trying to figure out ldap auth with mongodb all day today.
15:20	sveri	Poky: funny, yea, I wanted to try it out, it's interesting to stay motivated like that
15:21	sveri	ouch, ldap :D
15:21	sveri	I never liked that, is it a requirement you have?
15:21	sveri	Poky: and btw. do you know that article: https://aphyr.com/posts/322-call-me-maybe-mongodb-stale-reads about mongodb?
15:21	clojurebot	Huh?
15:22	Poky	yeah I tried that with github, but you need a concrete project in order to make it work.. like closp :D
15:23	Poky	it's just for an assignment.. I need to secure the server and picked mongodb as the application running on it.. I really don't even know why ldap is part of it
15:23	sveri	Hehe, I see
15:24	Poky	I don't even know what it's good for tbh. Like why do I need ldap for authentication over mongodb..
15:24	Poky	just another db for users over db
15:24	sveri	ldap is more like active directory than like a database
15:24	sveri	and it is widely used as a business / groups / user backend
15:26	Poky	could be... as I said, I've never seen it before. I don't even know what I am doing. :D
15:27	sveri	Poky funny, I wish you good luck with that. I only managed once to get a ldap backend working for me and it was one of the most painful experiences and I said that in relation to the fact that I even had windows 3.1 running on my desktop some time ago :D
15:27	sveri	*say
15:29	Poky	well that's encouraging isn't it :D I mean tutorial on monodb http://docs.mongodb.org/manual/tutorial/configure-ldap-sasl-openldap/ is really short. so it's probably my fault
15:29	Poky	doesn't help that their repositories aren't working for the debian server I have running.. so I don't even know if I have the enterprise version that can do it.. ;D oh well, it'll get done. somehow. :D
15:29	sveri	Ok, some motivation, the last time I tried ldap is like 8 to 10 years ago, so I guess things have become better and easier in between :D
15:30	sveri	virtual machines or better, docker will be your friend there. heck, maybe you find docker images for that
15:31	Poky	well I've never touched mongodb, I've never seen ldap.. I guess I might as well add docker to the mix if I get desperate
15:32	sveri	take the docker tour on the website, it is really easy to get started with, on the other hand, you are right. two new technologies are usually one to much, adding a third won't make things easier
15:34	Poky	well, I have to mongodb running OK. I have acess to ldap via some phpuglyadmin.. now I just need to figure out how to make them talk I think :)
15:34	sveri	ok, then just do that
15:34	sveri	no need for a third layer :D
15:34	Poky	but docker is definitely on my list of things to play with. seems to be hot nowdays
15:35	sveri	Poky: it is and it does make things easier, but it has it's limits and they are pretty tight
15:39	gfredericks	limits?
15:41	dviramontes	hi, anyone here using Figwheel with Quil.cljs ?
15:43	sveri	gfredericks: well, it's a best practice to only run one service in one container, part of the reason is they replaced systemd by fakesystemd which makes it hard to run several services. You have to know in advance which ports you will have opened inside your container. Only some operating systems are supported as hosts / "guests", every user belonging to the docker group has basically root access, which is by design and maybe some mor
16:16	gfredericks	hmm; yeah.
16:52	thatguy	I'm passing a map to yessql for saving data. Any convenient way to get the correct keys out of the params map, into this "entity" map?
16:52	thatguy	Thinking now just to have a list of the db keys in a var, that i could use to copy
16:53	thatguy	or is there a way to say, only copy keys that match the target map? i'm new, obviously
16:59	tomjack	target map?
16:59	tomjack	"only copy keys that match the target map" sounds like "only copy the keys I want to copy" to me
17:02	tomjack	in other words, please elaborate and/or give example input/outputs you want
17:09	arohner	,(doc select-keys)
17:09	clojurebot	"([map keyseq]); Returns a map containing only those entries in map whose key is in keys"
17:09	arohner	thatguy: ^^ ?
17:22	sohalt`	Hi, I'm trying to get a ClojureScript REPL running and having no luck with both the node and the brepl one. (I used the lein mies template) The brepl one hangs and the node one gives me a "TypeError: Cannot read property 'call' of undefined"
17:23	sohalt`	Any ideas what I'm doing wrong?
17:23	bbloom_	sohalt`: are you trying to use the absolute latest version of cljs? seems like dnolen is actively changing the repl & there have been a few bugs/regressions/etc
17:26	sohalt`	bbloom_: I'm trying to use 0.0-2755 -- that's the one specified in the lein mies template. Not sure, whether it's the absolute latest.
17:27	bbloom_	that's a bit old, which is probably a good thing :-)
17:29	sohalt`	Oh, ok. I'll try a newer one. Also I noticed the node repl and brepl scripts in the mies template differ from what the quick-start page in the wiki says.
17:30	bbloom_	i couldn't get 3211 to work for me, but 3196 worked fine. dnolen hasn't popped up for me to bug him about it
17:30	bbloom_	i just changed the url to download the jar
17:30	bbloom_	cljs.jar is super easy to get started w/ compared to pretty much everything else
18:01	slipset	I've got this thing in core.async which is causing me some head-ache
18:01	slipset	the code is here https://gist.github.com/slipset/7cf68e62d82fb50ae587
18:01	slipset	My expectation is that Even should only serve even customers, and Odd should only serve odd customers,
18:02	slipset	but a typical run of this ends up a mix of odds and evens for both Odd and Even.
18:07	weavejester	bbloom_: Are you using 3211 with Clojure 1.7.0-beta1 or later?
18:08	bbloom_	weavejester: https://github.com/clojure/clojurescript/wiki/Quick-Start#clojurescript-compiler says "The standalone ClojureScript JAR comes bundled with Clojure 1.7.0-Beta1."
18:09	weavejester	bbloom_: Ah :)
18:17	sohalt`	Hm, no luck with the jar (3211) aswell. The repl displays "Waiting for browser to connect ..." and then hangs
18:17	sohalt`	I'll try 3196
18:20	sohalt`	Yes! "cljs.user=>" Thanks!
18:25	sohalt`	Does anybody have a recommendation for a library to modify svg from clojurescript?
18:29	thatguy	(let [entity {:b 20 :c 30}
18:29	thatguy	req {:a 1 :b 2}]
18:29	thatguy	(merge
18:29	thatguy	entity
18:29	thatguy	(select-keys req (keys entity))))
18:30	thatguy	If anyone cares, that's my solution from the help i got earlier. thx all
19:10	tahmid	Hello guys
19:10	tahmid	I am trying lein-droid
19:10	tahmid	But I can’t change the background color of my image-view
19:11	tahmid	In java I can write imageView.setBackgroundColor( Color.parse(“FFFFFF”));
19:11	tahmid	But I can’t import the color class
19:12	tahmid	Help me please
19:12	justin_smith	tahmid: what is the full package of Color?
19:12	tahmid	android.graphics.Color
19:13	justin_smith	and what did your import look like?
19:13	tahmid	(import ‘[andorid.graphics.Color])
19:14	justin_smith	(import android.graphics.Color) or (import (android.graphics Color))
19:14	justin_smith	wait, I think that second one needs a '
19:15	tahmid	Nope
19:15	tahmid	It worked
19:15	justin_smith	,(import '(java.util UUID))
19:15	tahmid	thanks
19:15	clojurebot	java.util.UUID
19:15	justin_smith	np
19:15	tahmid	(import android.graphics.Color) worked
19:15	tahmid	(inc justin_smith)
19:15	lazybot	⇒ 246
19:15	oddcully	also this looks like a rather odd '
19:15	justin_smith	yeah, the second one is handy if you want multiple things from one package though
19:16	justin_smith	ah!
19:16	justin_smith	,(import (java.net URL URI))
19:16	clojurebot	java.net.URI
19:16	tahmid	nice
19:16	justin_smith	forgot that worked without the quote (works with it too though)
19:17	tahmid	should I ever use vector like in the :require form
19:17	justin_smith	tahmid: vector vs. list are both accepted, but list is the first choice for import, vector is the first choice for require
19:17	bitcycle	Hey all. I've got leiningen-2.5.0 installed via brew but lein plugin install compojure-app isn't working. :( Can someone tell me what I'm doing wrong?
19:18	justin_smith	"lein plugin install" is a thing with lein 2?
19:18	tahmid	lein new compojure Your_App_Name
19:19	bitcycle	justin_smith: how would I install compojure-app project template?
19:19	justin_smith	you don't install templates, you instantiate them
19:19	justin_smith	like tahmid said
19:19	bitcycle	ah, and how does the lein tool know where to get the templates?
19:19	justin_smith	for actual plugins, you add them to your ~/.lein/profiles.clj or to your project.clj
19:20	justin_smith	bitcycle: it finds them the same way it finds any other library, it looks for packages called lein-template iirc
19:20	weavejester	bitcycle: It looks for a project called <whatever>/lein-template in clojars.
19:20	oddcully	bitcycle: lein new --help
19:20	bitcycle	justin_smith: I'm super new to the-JVM/clojure -- coming from Python/C++.
19:20	bitcycle	justin_smith: just wondering about where the libs live out on the interwebs.
19:21	justin_smith	bitcycle: OK. I think you'll find clojure/lein super weird at first, but eventually grow to like it
19:21	oddcully	bitcycle: bitcycle ~/.m2 most of the time
19:21	bitcycle	oddcully: huh?
19:21	justin_smith	bitcycle: it uses repositories like clojars and maven-central and sonatype, then it caches them under your ~/.m2/repositories/
19:21	oddcully	bitcycle: bitcycle ~/.m2/repository to be exact
19:21	bitcycle	oddcully: m as in maven?
19:21	weavejester	bitcycle: By default Leiningen has two Maven repositories it uses to find packages.
19:21	oddcully	bitcycle: m as in maven
19:21	bitcycle	Ah.
19:22	weavejester	bitcycle: Maven Central (https://search.maven.org/) and Clojars (https://clojars.org/)
19:22	bitcycle	Ok. That makes more sense. Thanks for helping, guys.
19:22	tahmid	clojure for android is getting better and better
19:22	weavejester	bitcycle: The ~/.m2 directory is where packages are locally cached.
19:22	justin_smith	tahmid: cool, that's good to hear
19:22	justin_smith	I have a 1.7 repl installed, but have only played with it briefly
19:23	bitcycle	weavejester: is there a well-known dependency repo on the interwebs similar to python package index (pypi)?
19:23	oddcully	bitcycle: mavencentral, jcenter
19:24	justin_smith	clojars.org also has an index to its packages
19:24	oddcully	bitcycle: clojars of course for clojure things
19:24	bitcycle	lol. clojars.
19:25	weavejester	bitcycle: Maven Central is generally used for Java packages, Clojars is used for Clojure packages.
19:25	bitcycle	and I thought the Python community was cheezy with their names.
19:25	justin_smith	bitcycle: we have some super bad ones
19:25	bitcycle	weavejester: cool, cool.
19:25	oddcully	bitcycle: if you are on lein you can install the `plz` plugin, which makes adding new stuff really a nobrainer: lein new app; cd app; lein plz add instaparse
19:25	justin_smith	bitcycle: lazybot uses a lib called irclj
19:25	bitcycle	oddcully: doesn't adding a new lib simply mean updating the project file?
19:26	oddcully	bitcycle: sure, but you would have to get the version number first
19:26	weavejester	bitcycle: "lein-plz" is just a plugin that automates the updating, IIRC
19:26	weavejester	But I tend to find it useful to start off doing things the "long way" before using shortcuts.
19:26	justin_smith	bitcycle: yes, it just updates the project.clj for you (finding latest stable version)
19:27	bitcycle	oddcully: shouldn't you _want_ to know the version you're pinning?
19:27	bitcycle	:)
19:27	bitcycle	I guess it does that for you. ...
19:27	justin_smith	there is also pallet/alembic for updating your deps at runtime in a repl without restarting
19:27	bitcycle	Nice.
19:27	justin_smith	(almebic.still/load-project) loads up any new deps
19:27	oddcully	bitcycle: at project start i gladly take the recent one. and even if not: saves my typing in the first place
19:28	justin_smith	alembic won't drop deps though, only add new ones
19:29	oddcully	bitcycle: i also have my mavensearch twoliner script. i am lazy! searching websites bores me to death. a pip/easy_install user should know the value of such tools ;)
19:29	bitcycle	for sure. you guys are making it super easy and nice to get into clojure. Thanks for that. I'm prepping for a sysad role working with tomcat and what-not -- so I figured I would brush up on the jvm.
19:31	bitcycle	not sarcastic, I promise.
19:31	bitcycle	:)
22:11	brainproxy	i'm getting a "call to static method invokeStaticMethod on clojure.lang.Reflector can't be resolved", related to invoking `lein run` when I have a warn-on-reflection set to true via :global-vars
22:12	brainproxy	but in my testing profile, I have it set to true also and made sure I'm not actually doing any reflection
22:20	justin_smith	have you changed the version of your clojure dep recently? if so try lein clean
22:52	arrdem	Anyone know of a library function f which replaces all regex matches in a string s with f of the match?
22:57	justin_smith	,(clojure.string/replace "hello world" #"[^ ]+" (fn [s] (str s "ay")))
22:57	clojurebot	"helloay worlday"
22:57	arrdem	shit.
22:58	justin_smith	hiding in plain sight
22:58	arrdem	now I just feel bad
22:59	arrdem	there are even examples of that behavior on Grimoire
22:59	arrdem	okay I'll take it
23:02	TEttinger	(inc justin_smith)
23:02	lazybot	⇒ 247
23:02	arrdem	(inc justin_smith)
23:02	lazybot	⇒ 248

23:03	TEttinger	arrdem, was it you or gfredericks who did that amazing test.chuck regex generator?
23:03	justin_smith	,(clojure.string/replace "hello world" #"[^ ]+" (fn [s] (str (subs s 1) (first s) "ay"))) ; better pig latin
23:03	clojurebot	"ellohay orldway"
23:03	justin_smith	TEttinger: that was gfredericks
23:03	justin_smith	and that was a work of genius
23:04	TEttinger	arrdem makes the prancy pony that is grimoire, right
23:04	TEttinger	heh
23:04	justin_smith	and oxcart
23:05	arrdem	justin_smith: currently using that <platform>::<ns>/<n> notation all over Grimoire
23:05	justin_smith	cool
23:05	arrdem	now if you just use that in a markdown file somewhere it'll automagically generate the link and insert it
23:05	justin_smith	oh, nice
23:06	TEttinger	I am really looking forward to getting out of javaland. I've been writing lots of these gnarly heavily-mutable array- and map-based things for a game lib. I've written these before in clojure, most of them, and performance is uh a concern
23:06	arrdem	would it be... presumptive to PR the clojure cookbook repo adding Grimoire links all over the place?
23:06	arrdem	just an idea I had
23:23	arrdem	and it's working!
23:23	justin_smith	cool
23:23	TEttinger	nice
23:23	TEttinger	that was fast
23:24	justin_smith	amazon is now offering GaaS http://www.marketplace.org/topics/business/final-note/now-amazon-will-let-you-rent-goats
23:24	arrdem	ahaha
23:26	justin_smith	actual link http://www.amazon.com/exec/obidos/ASIN/B00UBYDXXQ
23:28	arrdem	hum... so it sorta kinda works in that if you say clj::foo/bar it'll give you _a_ link to that but if you're on an old version now you don't want the link to the _newest_ version of that you want the link to _this_ version of that.
23:28	arrdem	sigh
23:39	arrdem	Is there a good way to do Maven package introspection?
23:40	justin_smith	http://eclipse.org/aether/ like what aether does?
23:41	arrdem	probably
23:41	justin_smith	arrdem: maybe the Artifact class http://download.eclipse.org/aether/aether-core/1.0.1/apidocs/org/eclipse/aether/artifact/Artifact.html
23:42	justin_smith	arrdem: of course we have a nice clojure frontend to aether https://github.com/cemerick/pomegranate
23:43	arrdem	oh thank the Old Ones
23:43	arrdem	(inc justin_smith)
23:43	lazybot	⇒ 249

23:45	arrdem	I'm thinking that I could probably try to tack artifact metadata into the Grimoire datastore and then resolve the "right" version of whatever def you refer to with a short name from that context.
