01:45	johann_	hey room. i'm working on a project where i grab images off the web and display them in quil
01:48	johann_	i'm using http-kit to grab the images and it returns a promise with the response. in the body there is a byteinputstream of the image
01:48	johann_	the thing that i am confused about is going from byteinputstream to bufferedimage
01:50	johann_	i'm using the javax.imageio.ImageIO/read method and passing in the byteinputstream and it seems kind of arbitrary when it works without error or when i get a nullpointerexception
03:51	H4ns	i got a clojure design question: i have a set of restful handlers that operate on a persistent model, and i would like to send out asynchronous messages into the rest of my system whenever certain handlers are called. now, what is the best way to make the core.async channel available to the handlers?
03:52	H4ns	i'm using compojure for routing, so i use defroutes to define the routes and a bunch of ring middlewares. now, somehow i fail to come up with a good idea how i could install the routes and at the same time pass the channel to the handlers. any ideas/examples?
03:54	H4ns	or maybe i don't want to pass a channel at all, but rather use some higher level library that allows another component to observe the handlers?
04:01	kungi	H4ns: I recently had a similar problem where I needed to inject a component as dependency into a bunch of routes.
04:02	kungi	H4ns: Have a look at this macro here for inspiration: https://github.com/ggenikus/comcomp
04:02	kungi	H4ns: but beware this macro has some serious flaws.
04:03	kungi	H4ns: The idea is to inject the dependency into each request when it reaches a route
04:03	H4ns	kungi: thanks! i'll have a look.
04:04	H4ns	kungi: i've just found wrap-routes, which may actually be all that is required.
04:04	kungi	H4ns: wrap-routes?
04:04	H4ns	kungi: http://weavejester.github.io/compojure/compojure.core.html#var-wrap-routes
04:09	H4ns	hm. maybe not. there ought to be a very simple, macro-less solution.
04:15	magopian	is "Arne Brasseur" (@plexus) here?
04:17	dysfun	is there a collection library that evicts things on a LRU basis up to a specified limit?
04:20	dysfun	hrm, looks like LinkedHashMap can be used in this way
05:26	perplexa	cfleming: i didn't have time to look into it yet, sorry :)
05:26	perplexa	gonna play around a bit with cursive at the weekend
05:34	kenrestivo	i vaguely remember seeing a project someone did that would show you the github projects which depend (via lein project.clj) on some given project
05:35	kenrestivo	if that makes any sense. basically, a nice tree or search that would show what projects make use of which libraries
05:42	kenrestivo	nm, found it: https://github.com/search?q=foobar+filename%3Aproject.clj&type=Code&ref=searchresults
05:51	cfleming	perplexa: Ok, cool - let me know if you have problems, either here or by email
05:51	cfleming	kenrestivo: Check out http://crossclj.info, it's really great
05:51	perplexa	alrighty :) thx
05:54	kenrestivo	cfleming: wow, that's pretty amazing. and very helpful for comprehending the projects of people who :refer :all
05:55	cfleming	kenrestivo: No doubt, I use it a lot to see how people are using functions I'm interested in too.
05:55	cfleming	kenrestivo: The UI is pretty dense and takes some getting used to, but it's really powerful.
06:06	kenrestivo	who wrote that? is it based on codeq/datomic? great stuff.
06:07	ro_st	what are you talking about?
06:07	ro_st	crossclj?
06:08	cfleming	kenrestivo: It's written by Francesco Bellomi. It's not open source right now, AFAIK it's not codeq or datomic.
06:08	cfleming	ro_st: Right.
08:38	kungi	I am trying to load css files i bundeled into an uberjar like this: (io/file (io/resource "public/bootstrap/css/bootstrap.css"))
08:38	kungi	But I receive a IllegalArgumentException "Not a file"
08:39	kungi	jar:file:/Users/kungi/Code/clj-demgen/target/clj-demgen-2.0.7-standalone.jar!/public/bootstrap/css/bootstrap.css
08:39	kungi	What am I doing wrong here?
08:54	kungi	Meh! I found it. I cannot access a file in a jar file in that way.
08:58	ordnungswidrig	kungi: (io/resource "…") should be sufficient and will return you an inputstream IIRC.
09:00	kungi	ordnungswidrig: Yes but I wanted to get the lastModified time
09:01	kungi	I solved the problem as follows:
09:01	kungi	(defn- get-last-modified [url]
09:01	kungi	(.. (io/resource url)
09:01	kungi	(openConnection)
09:01	kungi	(getLastModified)))
09:01	kungi	ordnungswidrig: where are you from in germany?
09:01	ordnungswidrig	kungi: neu-ulm
09:01	kungi	ordnungswidrig: quite "near". We are creating a new clojure user group in mannheim
09:02	ordnungswidrig	kungi: that will only work as long as the resource is loaded from a jar. not every implementation or "UrlConnection" supports "getLastModified".
09:02	clgv	kungi: you have a different definition of "near" ;)
09:02	kungi	clgv: that's why I said 'quite :-)
09:02	ordnungswidrig	I might give a visit to that group some when. If you like I can give a talk on liberator or web dev.
09:03	ordnungswidrig	clgv: kunig is using the american midwest definition of "near"
09:03	kungi	ordnungswidrig: Hmm it seems to work when I run it outside of a jar in lein repl
09:03	clgv	ordnungswidrig: hehe
09:04	kungi	:-D
09:04	agarman_	kungi: the behavior will be surprising if your URL starts with something other than file://
09:05	kungi	agarman_: hmm can this happen when I use it on something created by (io/resource)?
09:06	ordnungswidrig	kunig: that depends on the classloader
09:06	kungi	ordnungswidrig: Now we reach the end of my Java knowlege.
09:06	ordnungswidrig	kungi: and beware that a classloader normally does not reload resources. Therefor I question whether it's useful to determine the last modification date of a resource
09:07	agarman_	kungi: yeah, what ordnungswidrig said :-)
09:07	ordnungswidrig	kungi: maybe you can describe what you want to achieve more generally
09:09	kungi	I want to force the browser to reload css and js files which have changed since the last visit.
09:09	agarman_	don't put them in resources then
09:09	kungi	I determine the last modified date and append it to the url
09:10	ordnungswidrig	kungi: https://github.com/mmcgrana/ring/wiki/Interactive-Development
09:10	elfenlaid	hi all, quick silly question, are there some analog of haskell's STM:retry in clojure or I must use watcher?
09:10	ordnungswidrig	ups, wrong link
09:10	ordnungswidrig	elfenlaid: yep, lookup (ref) (dosync) et. al.
09:11	kungi	ordnungswidrig: Looks wrong
09:11	elfenlaid	ordnungswidrig: thank you :)
09:12	ordnungswidrig	kungi: https://github.com/weavejester/lein-ring is able to reload on change
09:12	kungi	ordnungswidrig: Yes but this does not prevent the browser of my client from caching my js files
09:12	ordnungswidrig	kungi: if you only need it for dev, then you might be able to depend on file:///… urls and just not fail else
09:12	agarman_	kungi: you need to include ring-dev middleware
09:13	ordnungswidrig	kunig: you should serve a proper last-modified header then
09:13	kungi	ordnungswidrig: no not only for dev
09:13	kungi	When I deploy a new version of my webapp I want to force the clients browser to reload the css and js files that have changed
09:14	ordnungswidrig	oki, "wrap-not-modified" is your friend here. https://github.com/ring-clojure/ring/wiki/Static-Resources
09:14	agarman_	https://clojars.org/ring/ring-devel
09:16	kungi	ordnungswidrig: looks like that's exactly what I need
09:21	kungi	ordnungswidrig: Thank you!
09:25	arrdem	cfleming: killed the old Grimoire instance. no idea how that survived.
09:26	arrdem	cfleming: yeah there will be a Grimoire 0.4.0 with a omnipresent search box for keyboard only nav at some point
09:27	arrdem	cfleming: blockers on that are my learning clojurescript, free time and a couple solid UX sketches
09:50	elfenlaid	I end up with like this http://dpaste.com/3V0TH3Z , another interesting question is should I worry about an overhead of add-watcher \ remove-watcher ?
09:59	kungi	ordnungswidrig: When using ring.middleware.not-modified in an uberjar I get two content-length headers with the same value in the respones.
09:59	kungi	ordnungswidrig: This create weird errors.
10:00	kungi	ordnungswidrig: Do you have a pointer where I might start to debug this?
10:01	ordnungswidrig	hmm, that's a good question
10:10	clgv	elfenlaid: what exactly are you trying to solve with that?
10:27	elfenlaid	clgv: well, I'm planning to build a toy spider with configurable number of connections per host
10:28	clgv	elfenlaid: ok. what does this concrete piece of code try to achieve?
10:29	justin_smith	shared queue and each thread taking URLs from the queue to visit and depositing URLs from links would be much more straightforward
10:30	elfenlaid	justin_smith: actually your are right :)
10:31	elfenlaid	clgv: it's kind of connections queue
10:31	xeqi	elfenlaid: have you considered a ThreadPoolExecutor ?
10:32	elfenlaid	xeqi: well, no :) I will google for that, thanks :)
10:33	justin_smith	yeah, a ThreadPoolExecutor and a ConcurrentLinkedQueue seems like a natural combo for this
10:34	clgv	elfenlaid: yeah, you should use a threadpoolexecutor to limit the number of parallel activities
10:34	clgv	elfenlaid: that's why I asked ;)
10:36	corecode	hi
10:36	corecode	what's the suggestion to use swt with clojure?
10:37	corecode	i'm a total newb to clojure and java; i can't find a recent swt package in clojars or maven
10:38	elfenlaid	clgv: trying to mix channel in that monster :) http://dpaste.com/3Q0E31A
10:38	justin_smith	corecode: well there is a maven repo for swt https://code.google.com/p/swt-repo/
10:39	corecode	justin_smith: so eclipse can't figure it out themselves?
10:39	corecode	oh my.
10:39	justin_smith	?
10:39	justin_smith	I don't know
10:39	justin_smith	yeah looks like it
10:39	corecode	now i just need to figure out how to use this repo with lein
10:40	clgv	elfenlaid: no, just forget that monster
10:40	verma	so if I have a javascript object and I need to access a property like: positions.attributes.position.array, is there something more elegant than (.-array (.-position (.-attributes positions))) ?
10:41	clgv	corecode: are you sold on SWT? since there is the awesome seesaw library for swing
10:41	justin_smith	corecode: [org.eclipse.swt/org.eclipse.swt.win32.win32.x86_64 "4.4"] in your deps vector
10:41	elfenlaid	clgv: if you say so :)
10:41	justin_smith	yeah, seesaw will likely be much more peasant to use
10:41	corecode	clgv: i am not committed at all
10:41	clgv	corecode: afaik there is no port for SWT so far
10:41	corecode	clgv: i'm trying to learn a bit of opengl and clojure
10:42	corecode	justin_smith: that probably won't work for linux?
10:42	justin_smith	corecode: on that page they list the artifact ids for other platforms
10:43	justin_smith	I was just showing the translation from pom.xml syntax to project.clj
10:43	justin_smith	(of course you need to add their repo to :repositories too)
10:43	clgv	corecode: I think there should be a portable dependency for SWT
10:44	TravisD	Does anyone know of any papers talking about stopping rules for random restarts for global optimization?
10:44	corecode	justin_smith: i was more wondering how i can add the repo url
10:44	justin_smith	clgv: so what, it would ship every platform version?
10:44	corecode	but sure, i can try to use seesaw
10:45	justin_smith	corecode: relevant part of the sample project.clj https://github.com/technomancy/leiningen/blob/master/sample.project.clj#L78
10:45	Luyt_	iamdustan: Having any luck with Clojure on codeeval.com yet? My solutions also get rejected because they take too much memory (120MB for example). The hint I get is "Reduce memory usage to 20MB or less". Easier said than done!
10:45	justin_smith	corecode: there is little to nothing about project.clj construction that is not answered by example in that marvelous file
10:46	clgv	justin_smith: yeah, I think there is an option to do that similar to how other native libraries are handled
10:46	justin_smith	Luyt_: with clojure, that is going to be pretty difficult
10:46	justin_smith	clgv: and how are they handled? by shipping all the common native deps in the uberjar?
10:46	Luyt_	justin_smith: I agree. Codeeval should adjust their memory usage criteria for submitted solutions in Clojure.
10:47	clgv	justin_smith: yeah probably. I think for dev it should be fine, but for releases you probably only want to have platform specific builds to limit jar file size
10:47	justin_smith	yeah - not that we limit size of much of anything in the clojure world :P
10:48	Luyt_	justin_smith: There was some discussion about it on https://getsatisfaction.com/codeeval/topics/clojure_time_memory_stats_seem_wrong , but I think it has low priority at codeeval.
11:34	clgv	Luyt_: well memory usage is a matter of configuration of the used jvm as well. how do they do it for java?
11:35	Luyt_	clgv: I don't know ;-) I can't look into the kitchen of Codeeval.com ;-)
11:36	Luyt_	clgv: Oh, and I've never submitted a Java solution. Do they accept those, too?
11:36	clgv	Luyt_: java is listed in the ranking screenshots
11:37	Luyt_	clgv: Oh! Maybe they've tuned the criteria for Java solutions more careful than for Clojure. But I'm not interested in writing Java, I want to submit my solutions in Clojure!
11:38	justin_smith	clgv: my guess is that the java code is rated on the runtime mem usage as opposed to the compile time usage. in clj land we bring out compile time into runtime.
11:38	clgv	justin_smith: hmm maybe.
11:39	justin_smith	otherwise c++ would not do very well
11:41	clgv	they should just prestart a repl and then load the solution file and start the evaluation. but I guess they want to stay with their commandline approach
11:48	clgv	justin_smith: btw it seems there is no portable maven artifact for swt - maybe I confused it with a different lib relying on native dependencies
11:49	m1dnight_	Is it normal that (def varname...), not on to in a let body, gives a warning in Cursive?
11:49	m1dnight_	varname can not be resolved
11:50	m1dnight_	But everything works fine :)
11:50	clgv	huh?
11:50	m1dnight_	*not on top
11:50	clgv	m1dnight_: you mean like (let [...] (def varname ...)) ?
11:50	m1dnight_	yes
11:50	m1dnight_	(I know i should put it in the let, but I did it while experimenting
11:50	clgv	m1dnight_: that's a very bad idea and show that you did not understand the destinction between variables and local bindings
11:51	Bronsa	clgv: how is that a bad idea?
11:52	Bronsa	it's certainly not used much, but there's nothing wrong with it
11:52	clgv	Bronsa: ok some contex info is missing - I assume the `let` is within a function. which is the most frequent case when this is reported ;)
11:52	clgv	for a few variables I use a surrounding `let` as well...
11:52	m1dnight_	_experimenting_
11:53	clgv	m1dnight_: I guess it might be a feature of cursive's code analyzer?
11:53	m1dnight_	But the warning "can not be resolved" implies it can't find the variable in scope, but it is so I'm not sure wether it's a bug or a feature
11:54	justin_smith	m1dnight_: pragmatically speakign, a def inside a let, whether inside a defn or not, is rarely needed, and very frequently a sign that someone is making a beginner mistake. I can see how this would not be a priority case for the cursive analyzer to get correct.
11:54	clgv	m1dnight_: a bug of the analyzer is possible as well ^^
11:55	m1dnight_	justin_smith: I know, I know. I was just experimenting with proxies and swing so I quickly put in a def to try it out
11:55	m1dnight_	Nothing is set in stone here :p
11:55	clgv	is cursive opensource?
11:55	justin_smith	m1dnight_: right, just saying cursive has likely had few test cases like this
11:55	justin_smith	so the chances it has weird corner case behavior is high
11:55	Bronsa	clgv: don't think so
11:56	m1dnight_	cfleming: ^ Perhaps you are interested.
11:57	clgv	Bronsa: hmm yeah, would probably reduce the chances to sell it later on (as announce in its beginning)
11:58	justin_smith	m1dnight_: yeah, cfleming is the cursive dev
11:58	justin_smith	m1dnight_: cursive has a bug tracker, right?
11:58	m1dnight_	Not sure, I wanted to make sure I'm not overseeing something beforeI report a bug
11:58	m1dnight_	So I'll do that right away :)
11:59	m1dnight_	overlooking*
11:59	justin_smith	m1dnight_: https://github.com/cursiveclojure/cursive you can probably create an issue here
11:59	justin_smith	looks official
12:00	kungi	Is anyone working at http-kit?
12:01	justin_smith	kungi: as in being a http-kit developer, or as in using it in production?
12:01	kungi	justin_smith: I think both is appropriate
12:01	justin_smith	I use http-kit in a few projects
12:02	kungi	justin_smith: have you ever used ring.middlerware.not-modified with http-kit
12:02	justin_smith	no, not at all
12:03	kungi	justin_smith: using this ring middleware in conjunction with the creation of an uberjar results in http-kit delivering a response containing:
12:03	kungi	Content-Length: 101595
12:03	kungi	Content-Length: 0
12:03	kungi
12:03	kungi	Which just confuses every browser
12:03	justin_smith	yeah, that's weird
12:03	justin_smith	is this an http-kit specific issue?
12:03	kungi	Probably because of this: https://github.com/http-kit/http-kit/issues/127
12:04	kungi	justin_smith: I have not tested this with another server
12:05	justin_smith	you are right, this looks very similar to that issue - in fact, if I am reading correctly, the fix to that issue may have even caused this issue
12:06	kungi	justin_smith: the funny thing is: It only appears when I compile my code into an uberjar
12:06	justin_smith	kungi: what if you expanded the resources directory onto disk and loaded resources from there as a workaround?
12:07	justin_smith	just speculating that this would even work...
12:07	kungi	justin_smith: that might work, but I still don't understand why this happens
12:08	justin_smith	kungi: continuing to blantantly speculate... because you can't get a last modified time from a resource inside a jar?
12:09	kungi	justin_smith: I don't think this is correct.
12:09	justin_smith	not at all unlikely :)
12:09	kungi	justin_smith: Let me gist some stuff
12:11	justin_smith	sure - going out for coffee myself, be back shortly
12:11	kungi	justin_smith: https://gist.github.com/Kungi/4436d93ec8a99062fc09
12:11	kungi	justin_smith: I get a Last-Modified: date when querying the ubarjar version which seems to be correct.
12:12	justin_smith	you get double Content-Length headers in both cases
12:12	kungi	justin_smith: But in one case they match and in one they don't
12:12	justin_smith	that looks like an http-kit bug (or, very unlikely, a but in the not-modified middleware)
12:12	clojurebot	I don't understand.
12:12	kungi	justin_smith: That seems to be the "real" problem
12:12	justin_smith	yeah
12:13	justin_smith	have you considered making an uberwar via lein ring, and seeing if it behaves nicely in a tomcat or jetty container?
12:13	Bronsa	hallelujah http://dev.clojure.org/jira/browse/CLJ-1297#changehistory-21390
12:13	kungi	justin_smith: not yet
12:14	kungi	justin_smith: But I should do this
12:15	justin_smith	OK, getting coffee, brb
12:20	clgv	Bronsa: great :)
12:22	kungi	justin_smith: I updated the gist. When I query the uberjar version without an if-modified-since header I get the same discrepancy in context-length.
12:23	perplexa	hm.
12:24	perplexa	when i have a vector and i want only certain items based on attributes, i'd use reduce + into? or is there something else?
12:25	kungi	perplexa: filter?
12:25	PeregrinePDX	filter
12:25	noonian	^
12:26	Bronsa	filterv if you want a vector back
12:26	perplexa	i think i also need to transform them ;x
12:26	phillord	for with :when
12:26	Bronsa	,(map inc (filter odd? (range 10)))
12:26	clojurebot	(2 4 6 8 10)
12:26	perplexa	basically i have a set of java objects and want a different set of only paths ;p
12:26	PeregrinePDX	Yep what Bronsa said.
12:27	Bronsa	or as phillord suggests, ##(for [a (range 10) :when (odd? a)] (inc a))
12:27	lazybot	⇒ (2 4 6 8 10)
12:27	noonian	or 'for' if you are feeling fancy
12:27	perplexa	ok thx, map+filter looks like what i want
12:27	perplexa	,inc Bronsa
12:27	clojurebot	#<core$inc clojure.core$inc@1e9b69e>
12:27	perplexa	damn :D
12:28	clgv	perplexa: you are lucky it did not eval Bronsa ;)
12:28	perplexa	or for.. mmh :)
12:28	perplexa	haha
12:28	perplexa	you mean one of them is enough? :P
12:28	perplexa	(inc Bronsa)
12:28	lazybot	⇒ 56
12:29	perplexa	(inc phillord)
12:29	lazybot	⇒ 2
12:29	perplexa	\o/
12:29	perplexa	always a pleasure to leech your knowledge!
12:31	Bronsa	m1dnight_: fyi I just finished installing cursive and I don't see any warning for (let [a 1] (def b))
12:36	m1dnight_	strange..
12:36	m1dnight_	https://github.com/cursiveclojure/cursive/issues/527
12:36	m1dnight_	This is the issue
12:36	m1dnight_	Oh yes, it's only if the let is in the body of the function
12:36	m1dnight_	a top level let does not show the symptoms
12:38	justin_smith	m1dnight_: one complication could be that putting def inside a defn creates the var at the defn's compile time, but does not put any value into it
12:38	luxbock	does clojure.test have a built-in way of testing if a function is supposed to throw (a specific) error?
12:38	justin_smith	m1dnight_: when the defn is invoked, the var finally gets a value
12:39	justin_smith	luxbock: yes, the thrown-with-message syntax with is
12:39	clgv	m1dnight_: humm but the it looks more likea feature ;)
12:39	Bronsa	m1dnight_: ah that's more reasonable
12:40	luxbock	justin_smith: ah it's a special case of `is`, that's why I missed it
12:40	justin_smith	luxbock: or if you don't care about the message, just thrown? (is (thrown? the.exception.Type ...))
12:40	justin_smith	yeah, it's weird
12:40	Bronsa	m1dnight_: that code should definitely warn. it works in clojure mostly because of a side-effect of implementation details of def
12:40	luxbock	I've been using speclj but I think for my next project I'll just use clojure.test
12:42	luxbock	I keep accidently writing test functions that have errors in them but those errors never show up anywhere so I mistakenly think they work fine
12:42	luxbock	I guess I need to write tests for my tests
12:43	m1dnight_	Oh really? What is that then Bronsa ? You've piqued my interest :p
12:44	Bronsa	m1dnight_: nothing terribly interesting actually, just that vars get created at analysis time rather than at runtime to allow forms like (defn a ([] (a 1)) ([x] x))) to compile
12:45	justin_smith	m1dnight_: Bronsa: which is what I was trying to say above, though I called it "compile time"
12:46	Bronsa	justin_smith: sorry, I didn't read your message
12:47	justin_smith	np - is saying compile time simply less specific, or is it inaccurate in this case?
12:47	m1dnight_	Hmmm, I don't really know enough of about clojure's process so get it
12:47	Bronsa	just as good
12:47	m1dnight_	I can only relate to a scheme interpreter with a compilation step
12:47	m1dnight_	brb, going home :)
12:48	justin_smith	haha
12:48	Bronsa	justin_smith: actually, kinda inaccurate now that I think about it. if interning happened at compilation time, the snippet I provided would not compile
12:49	justin_smith	ahh, so there are separate analysis / compilation steps, and it needs to happen in the former
12:50	Bronsa	justin_smith: yeah, Compiler.java actually has different passes
12:55	bbloom	Bronsa: rich just changed one ticket from 1.8 back to 1.7 :-) heh
12:56	Bronsa	bbloom: two actually, the IAtom one and the catching - instead of _ one
12:56	bbloom	Bronsa: what's the catch one?
12:56	Bronsa	bbloom: but also marked as incomplete a bunch of ones without any comment :/
12:56	Bronsa	bbloom: http://dev.clojure.org/jira/browse/CLJ-1297
13:12	luxbock	how do I disable logging during my tests? I tired to use (timbre/set-level! :error) to only get :error-level logs but that didn't work and there's no doc-string for set-level!
13:17	mi6x3m	clojure, would you always keep the first named argument on the same line as the function name?
13:17	mi6x3m	(foo :boo "boo" vs. (foo\n:boo "boo" ?
13:18	mi6x3m	m1dnight_: seesaw?
13:18	m1dnight_	no, just proxies
13:18	justin_smith	mi6x3m: depends - with more than 3 args to assoc, I often put the first arg on the same line as assoc, and the rest with a new line per pair
13:18	m1dnight_	it's much cleaner than java, imo
13:18	mi6x3m	justin_smith: yes, exactly, but you don't put the first pair on a new line also?
13:19	justin_smith	(assoc m\n:a 0\n:b 1...)
13:19	mi6x3m	yeah I see, though so
13:19	mi6x3m	it's somehow intuitive but I get unsure sometimes
13:21	justin_smith	mi6x3m: this is not without controversial elements, but it's good m1dnight_:
13:21	justin_smith	err
13:21	justin_smith	https://github.com/bbatsov/clojure-style-guide
13:21	justin_smith	didn't mean to tag m1dnight_ there, sorry
13:22	mi6x3m	justin_smith: yeah, that guide is very nice, thanks :)
13:23	csd_	How would you compile/package a project that has two distinct processes that would run simultaneously? E.g. would you have two separate uberjars and -main functions?
13:23	justin_smith	csd_: how much do they share code?
13:24	csd_	One process scrapes into a db, the other process accesses the db
13:24	justin_smith	csd_: if more than a little, I would use the busybox approach (check the args to see which function -main dispatches out to)
13:24	martinklepsch	I'm going through the core.logic tutorial and wrote a sibling function: https://gist.github.com/mklappstuhl/4f35b0208a2ac0f7668e
13:25	martinklepsch	(based on the core.logic tutorial)
13:25	justin_smith	csd_: so how about one jar with one -main which calls either scrape-main or access-main depending on args?
13:25	csd_	oh thats not a bad idea
13:26	csd_	to be less vague, i want the scraper to run daily, while the other process provides a ring server
13:27	justin_smith	could the scraper be a scheduled task embedded in the same process?
13:28	martinklepsch	now that sibling function returns it's argument as well. how would I remove that from the result set?
13:28	arrdem	bbloom: wait - vs _ is back from 1.8?
13:28	csd_	i don't really know much about scheduled tasks. i had been debating using something like quartzite versus cron but figured i'd just use cron as it would be simpler to implement
13:28	bbloom	arrdem: seems so i guess. Bronsa spotted it
13:28	arrdem	bbloom: I saw that it got triaged approved, but I thought it was still 1.8. I welcome it...
13:29	csd_	if i used cron i could use your idea of calling main with a different argument
13:29	justin_smith	csd_: you could check out java.util.concurrent.ScheduledThreadPoolExecutor
13:30	csd_	what would you do? i just dont have enough experience to know what's best
13:30	bja_	is there a builtin schema for a function type?
13:30	csd_	bja: like IFn?
13:31	justin_smith	csd_: call .SceduleAtFixedRate on a (ScheduledThreadPoolExecutor.) - you can pass an fn of no args as the first method arg
13:32	bja_	I mean, IFn definitely works, but isn't IFn not clojure.lang.IFn in cljs?
13:32	justin_smith	csd_: well, I forgot to include the pool size in the constructor, but I think you will see that the API is straightforward
13:32	tac_	,(doc partial)
13:32	clojurebot	"([f] [f arg1] [f arg1 arg2] [f arg1 arg2 arg3] [f arg1 arg2 arg3 & ...]); Takes a function f and fewer than the normal arguments to f, and returns a fn that takes a variable number of additional args. When called, the returned function calls f with args + additional args."
13:32	csd_	justin_smith: thanks ill check that out
13:32	tac_	partial is partial application?
13:32	csd_	bja_: don't know about cljs sorry
13:33	justin_smith	tac_: yes, it returns a new function that takes N fewer arguments when supplied with a function and N args
13:33	bbloom	Bronsa: arrdem: can look at http://dev.clojure.org/jira/secure/ViewProfile.jspa?name=richhickey to see more complete 1.8 -> 1.7 recoveries... seems like the mass move to 1.8 wasn't so much rejection as opting for "opt in", which seems sensible
13:37	sevvie	to whomever published "Clojure in the Open", thank you.
13:40	hiredman	woa https://github.com/clojure/clojure/commit/8765800e23a057957986c7d2bbb1f09cd3f1a676
13:42	cfleming	m1dnight_ justin_smith Bronsa clgv: Right, that's more or less a feature of Cursive
13:43	cfleming	It'll index recursively from the top level inside let, do, etc as deep as you like but won't continue indexing inside defn
13:43	justin_smith	yeah, I think we narrowed it down that the error was in the code, not cursive's handling of it
13:43	justin_smith	declare would be a simple workaround if you really need the def to happen inside a defn
13:44	cfleming	Well, the code is valid for some definition of valid, i.e. it does actually work
13:44	cfleming	But it's unusual and not recommended, right
13:45	m1dnight_	cfleming: It seems to happen in this case as well: (defn f [args] (fn [arg1 arg2] (def something ..) ...)))
13:46	m1dnight_	(I happen to stumble upon this whilst translating a scheme program to clojure
13:46	m1dnight_	)
13:46	justin_smith	m1dnight_: if you really need to do that, (declare something) at the top level would eliminate the warning I think
13:47	m1dnight_	yeah, i'll leave it be for the moment and check if I can replace it with a let in the second pass
13:47	m1dnight_	I do have to read up on why exactly it is so bad to do this though
13:47	cfleming	m1dnight_: Right - that might be idiomatic in Scheme but it's not in Clojure
13:48	technomancy	m1dnight_: internal define in scheme is completely different from clojure's def
13:48	cfleming	Cursive will only look inside do and let-like forms (including letfn) from the top level.
13:48	justin_smith	def is for globals only in clj, and you are creating a global but not binding it when the form gets analyzed in the compilation stage, only when the function runs does the global finally have a value
13:48	m1dnight_	All I know is that in Scheme it acts the same as a let binding..
13:48	hiredman	clojure's def always defines a global var with a name
13:48	m1dnight_	I get it
13:49	m1dnight_	justin_smith: but (def x <val>) inside a function does not make it accesible out of the scope of the function body, or does it?
13:50	cfleming	m1dnight_: Yes, it creates a global var
13:50	justin_smith	it does
13:50	justin_smith	globals only
13:50	justin_smith	that's what everyone has been saying
13:50	technomancy	while it's not technically true, you can assume there's no such thing as a local var
13:50	m1dnight_	oh, well thats mindblowing (to me at least) :p
13:51	justin_smith	technomancy: easier just to say that def is only for globals I think :)
13:51	technomancy	justin_smith: there are no local vars that are worth using? =)
13:51	justin_smith	m1dnight_: very different from scheme
13:51	justin_smith	technomancy: you can make local vars, just not with def
13:51	m1dnight_	Okay now I get it :)
13:51	technomancy	justin_smith: you can and shouldn't.
13:53	justin_smith	wait, shouldn't create a local var with def or shouldn't create local vars?
13:53	technomancy	justin_smith: I mean it's best to pretend with-local-vars doesn't exist
13:54	justin_smith	hehe, OK
13:55	dbasch	without-local-vars
13:55	justin_smith	has someone created the "useless" lib yet?
13:57	technomancy	once they do I would happily take a PR updating lein's tutorial to use it
13:58	m1dnight_	what's the useless lib?
13:58	justin_smith	a running joke on this channel
13:58	justin_smith	includes functions like "without-redefs"
13:58	justin_smith	unconcat
13:58	justin_smith	(that one may be marginally non-useless actually)
13:59	m1dnight_	oh lol :p
14:00	dbasch	take-all and remove-all
14:00	justin_smith	flatten
14:00	justin_smith	oh wait that one is in clojure.core
14:01	dbasch	lol
14:01	technomancy	lol
14:01	Bronsa	(inc justin_smith)
14:01	lazybot	⇒ 88
14:11	gfredericks	I thought I might have something related that I actually created at some point; after 3 minutes crawling through my github repos I found https://github.com/gfredericks/clojure-useless
14:12	gfredericks	all it has is a roundabout identity function
14:12	gfredericks	patches welcome
14:13	technomancy	wow, created by lein1
14:13	technomancy	(C) <- how gauche we were in those ancient days
14:14	justin_smith	a remarkably well named namespace https://github.com/gfredericks/clojure-useless/blob/master/src/clojure_useless/core.clj
14:14	technomancy	I like that the file exists in the first place
14:14	gfredericks	technomancy: I should just make a commit out of `lein new`
14:15	technomancy	I choose to interpret it as a commentary on how dumb core.clj files are to begin with
14:15	justin_smith	technomancy: there are layers here to be sure
14:19	kryft	technomancy: Because there's no reason to have such a generic file name instead of a more descriptive one?
14:19	gfredericks	okay all the files have been enfreshinated
14:19	technomancy	kryft: yes, but more broadly because there's no reason for clojure to put single-segment namespaces in the default package
14:21	gfredericks	technomancy: would that be a breaking change?
14:21	technomancy	gfredericks: I don't think you could do it in a compatible way?
14:21	technomancy	also dumb: the requirement for underscores in file names
14:22	dbasch	gfredericks: perhaps my do-or-do-not macro https://www.refheap.com/91360
14:22	technomancy	it's the same insistence that .clj files map closely to their .class equivalence; it's wasted countless hours
14:23	gfredericks	technomancy: I mean what would break if it changed? just compiled code or something?
14:24	gfredericks	"it changed" meaning single-segment namespaces do something besides the default package
14:24	technomancy	gfredericks: I feel like if you assumed all java code calling clojure went through the official API you might be able to pull it off
14:24	justin_smith	dbasch: I like how my first glance of do-or-do-not leads me to think "I would wrap that in try/catch" - deep yoda joke there
14:24	technomancy	but given that the official API is relatively new (and even if it weren't, there would be people who didn't use it) odds are not great
14:25	gfredericks	technomancy: I'm glad I don't manage a language
14:25	technomancy	gfredericks: I guess to be fair when AOT was designed it wasn't clear what the patterns would be
14:26	technomancy	hindsight is 20/20 etc
14:26	gfredericks	technomancy: heck it's hard enough to even guess what functions you as the maintainer will think are useful 5 years out
14:26	technomancy	gfredericks: before AOT was added, there was no clojure.core, it was just clojure
14:26	technomancy	and a bunch of things broke, but there was nothing in production, so it was fine
14:26	gfredericks	technomancy: TIL
14:27	technomancy	if I've learned anything from tetris, it's that your achievements disappear and your mistakes pile up.
14:27	gfredericks	clojurebot: it is time for clojure history anecdotes with technomancy
14:27	clojurebot	c'est bon!
14:27	gfredericks	ha
14:28	joshuafcole	(inc technomancy)
14:28	lazybot	⇒ 140
14:28	joshuafcole	I expect to quote that for many years to come
14:28	technomancy	it's funny because there was a lot of hand-wringing about next vs rest breaking compatibility only ~ix months later
14:28	technomancy	~six
14:28	clojurebot	Gabh mo leithscéal?
14:28	technomancy	oops
14:29	gfredericks	I feel like I vaguely remember that
14:29	technomancy	that struck me as a much less invasive change
14:29	hiredman	the nil puning thing
14:29	technomancy	oh, but the book was almost ready to be printed, so that counts for a lot
14:29	gfredericks	oh so it was breaking book compatibility
14:30	technomancy	it's logistically pretty difficult to ship a patch for those things
14:31	joshuafcole	You'd have to mail the patch files themselves and gluesticks to merge them in with
14:31	gfredericks	and you pretty much have to make sure the length change is a whole number of pages
14:31	gfredericks	else you'd be patching like the whole second half of the book

14:37	danneu	is there a way to refer to the current function in its body without knowing the function's name? like (defn foo ([] (recur 1)) ([x] (println x)))?
14:37	TimMc	joshuafcole: :-D
14:37	joshuafcole	I didn't know you could brew install debian!
14:38	justin_smith	danneu: you can use recur just like that
14:38	TimMc	technomancy: Ship the book as a 3-ring binder in the first place. That helps.
14:38	TimMc	(with patches)
14:38	danneu	justin_smith: i get a mismatched arg-count to recur
14:39	joshuafcole	hah
14:39	borkdude	I thought about writing a leiningen plugin named "copy": it copies an entire project but changes the project name to "dest" in "lein copy dest"
14:39	dbasch	danneu: yes, just (recur)
14:39	TimMc	(note: this is actually a thing)
14:39	borkdude	maybe pretty useless ;)
14:39	dbasch	danneu: oh, you want to call another arity
14:39	csd_	justin_smith: any idea what's wrong with my syntax/usage?
14:39	csd_	((-> (ScheduledThreadPoolExecutor. 10) (.scheduleAtFixedRate #(println "hello") 0 5 TimeUnit/SECONDS)) (Thread/sleep 5000))
14:40	csd_	I'm getting an error about java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask cannot be cast to clojure.lang.IFn
14:40	justin_smith	csd_: looks like you have extra parens
14:40	justin_smith	yeah, extra parens will do that
14:40	hiredman	(foo bar) is calling foo with the argument bar
14:41	joshuafcole	rainbow parens + paredit were a huge quality of life improvement for me when I started to get serious about clojure
14:41	dbasch	danneu: why would you want to avoid mentioning the function name?
14:41	joshuafcole	extra/to few/mismatched parens became dramatically less likely
14:41	csd_	justin_smith: i don't think so
14:42	justin_smith	that thread does not return a thing you can call
14:42	hiredman	^- (foo bar) is calling foo with the argument bar
14:43	csd_	what do you mean? i was thinking that if you go into Thread/sleep that the scheduler would keep hitting the function
14:43	TimMc	danneu: Yes, you give the function another argument, and you call it like (foo foo ...) instead of (foo ...)
14:43	danneu	dbasch: it's painful. especially when it's early development and there's still a lot of churn in my fn names as i work things out. my i find out when i restart my jvm that half my fns refer to fns that dont exist anymore
14:43	justin_smith	csd_: your (-> ...) call is in the function position
14:43	justin_smith	csd_: it does not return a function
14:43	TimMc	and from there you're on your way to the y combinator
14:43	csd_	ohhhhhh
14:46	borkdude	cfleming to be honest I don't get the "default" build configuration thing in Intellij. how do you launch one, without copying one
14:47	justin_smith	csd_: without the extraneous parens or the sleep, that code runs for me
14:47	justin_smith	(once I import the proper classes)
14:47	cfleming	borkdude: Yeah, that is confusing. Think of the default builds as templates, which you copy to create your configs.
14:48	csd_	justin_smith: I wrapped it in a do loop, but I don't receive the println with or without the sleep statement
14:49	kenrestivo	is anyone using gloss with its new channel capabilities to do frame sync on a network stream? are there any examples out there (done some searching, haven't found anything quite yet)
14:49	justin_smith	csd_: it prints in the repl's terminal for me (even though I ran it in an emacs nrepl buffer) but I expect that of threads
14:49	pepijndevos	What's the deal with primecoin? Just go a primecoin for a merged Clojure patch. dafuq.
14:49	justin_smith	csd_: since out is a dynamic var
14:49	ztellman	kenrestivo: the channel capabilities aren't exactly new
14:49	csd_	oh there it is
14:49	ztellman	I think they're three years old at this point
14:49	ztellman	maybe more
14:50	csd_	that is something that is still confusing to me--which buffer cider prints to when

14:50	justin_smith	csd_: out is bound dynamically per thread, so new threads will look for the root binding, which isn't the repl window
14:50	justin_smith	csd_: yes, it is weird
14:51	csd_	how can i kill these threads in the repl?
14:51	ztellman	kenrestivo: check out https://github.com/ztellman/aleph/blob/master/src/aleph/formats.clj#L499
14:51	dbasch	pepijndevos: a primecoin is about $0.20
14:52	kenrestivo	ztellman: from the man himself! thanks!
14:53	pepijndevos	Is it like an official thing, or some random dude just put $5 on that site?
14:54	justin_smith	csd_: you need a handle to the executor or at least the task that got scheduled I think
14:54	justin_smith	csd_: though I think technically there is a way to get a collection of all threads, find yours, and mess with that directly
14:54	csd_	gotcha
14:54	csd_	ok thanks for your help with this

14:55	technomancy	pepijndevos: huh, sounds like bitcoin, except computing actually useful results instead of garbage?

14:55	technomancy	sure
14:55	technomancy	now if we could use it to detect extraterrestrial intelligence ... =)
14:55	pepijndevos	kinda like those @home screensavers haha
14:56	pepijndevos	That would be a valuable currency, one starcoin for every alien found.
15:10	danneu	kenrestivo: here's an example of using gloss to decode bitcoin msgs over the wire https://github.com/ztellman/gloss/issues/27#issuecomment-28149170 - though the gist doesn't actually demonstrate gloss.io/decode-stream, it's what i used in real life in place of that gloss.io/lazy-decode-all example
15:15	kenrestivo	danneu: thanks
15:18	borkdude	cfleming how about referring doc and source in repl by default?
15:19	TimMc	pepijndevos: Oh man, thank you for reminding me of SETI@home!
15:28	turbofail	interesting response to that "good bad and ugly" talk: http://www.cl.cam.ac.uk/~srk31/blog/2014/10/07
15:28	justin_smith	turbofail: yeah, I liked that article
15:28	turbofail	definitely captured some things that i was having trouble putting to words
15:29	puredanger	one thing I had hoped to do this year at Strange Loop was provoke conversation about typing (not with an agenda really other than having the conversation)
15:30	puredanger	so I'm chalking those articles up as a win :)
15:30	technomancy	I wrote out a ton of types over the weekend; it was a blast https://github.com/technomancy/cooper/blob/master/cooper/cooper.rkt
15:31	justin_smith	turbofail: puredanger: one thing I really liked about that article was positioning typing as a special case of invariants. Some of which can be expressed with type systems, some of which (currently) cannot. Most languages have some mechanism of describing and/or ensuring invariants, and we can have a productive conversation with a starting point like that.
15:32	puredanger	indeed, I think he captured some subtle points with clarity
15:38	turbofail	technomancy: where is that space dinosaur from?
15:38	technomancy	turbofail: http://midasflesh.com
15:38	technomancy	it's super-great
15:39	justin_smith	I can concur, it's an awesome comic
15:40	technomancy	it's a graphic novel about what if midas's flesh actually turned things to gold; the whole earth is a solid gold lump floating in space, discovered by a group of freedom fighters who try to harness his body as a superweapon.
15:40	technomancy	also one of the freedom fighters happens to be a dinosaur who uses lasers and jetpacks. need I say more?
15:40	turbofail	heh
15:40	m1dnight_	typesystem discussions are always kind of dangerous :p
15:40	m1dnight_	Will read the paper though, looks interesting

15:42	justin_smith	m1dnight_: on the contrary, type systems are very safe, now sit down in this chair and let us buckle you in nice and snug. What's that you say, you want to get up and get a drink of water? We'd like a viable proof of that please.
15:43	m1dnight_	hahaha :D
15:43	justin_smith	technomancy: btw, hypercard clone - cool!
15:43	hiredman	alternatively things you only discuss in polite company
15:44	technomancy	justin_smith: thanks! we'll see where it goes. it's been a lot of fun so far.
15:44	technomancy	hoping to post on my blog about it soon
15:47	mikerod	I thought the "good, bad, and ugly" talk on types was very opinionated and wasn't always strongly backed something concrete, other than feelings
15:48	mikerod	I was interested in being convinced of some points on typing, but instead just felt it was a "rant"
15:49	m1dnight_	hmm, if I pass (rest '(1 2 3)) to (fn [operands] ..) I get an error that I passed two arguments instead of one
15:49	m1dnight_	what am I missing here?
15:49	m1dnight_	Shouldn't rest be a list and thus operands be bound toa list?
15:50	Bronsa	m1dnight_: can you paste the actual code?
15:50	m1dnight_	sure
15:50	m1dnight_	hold on
15:50	m1dnight_	https://www.refheap.com/91364
15:51	m1dnight_	I would expect (evaluate-application) to receive a list, but it's not happening, for some reason
15:51	m1dnight_	oooh, the apply
15:51	m1dnight_	Now I get it
15:52	Bronsa	yeah, it's the apply on (evaluate-application operator)
15:52	Bronsa	m1dnight_: you want (fn [& operands] instead of (fn [operand] if I understand correctly
15:55	daGrevis	hi! is it bad to map fn with sideeffects?
15:56	justin_smith	daGrevis: only if you don't do it eagerly - it will just break if you use map for side effects and don't force the result
15:56	daGrevis	i need to call fn on each element in list and it doesn't work without doall so it feels kind of hackish
15:56	justin_smith	doseq?
15:56	clojurebot	doseq is like for, but for side effects instead of values
15:56	justin_smith	thanks, clojurebot
15:58	daGrevis	wow, thanks!
15:58	technomancy	I would say it's bad either way
15:58	daGrevis	til
15:58	technomancy	map indicates you're interested in values
15:59	daGrevis	well my exact situation is that i have webrtc connections and a send-data fn. i want to call send-data on each connection
15:59	daGrevis	like a foreach in python for example
15:59	daGrevis	technomancy, i don't care about return values
15:59	justin_smith	yeah, doseq is probably what you want then
16:00	scgilardi	technomancy: I think you've won me over on if vs. when
16:01	scgilardi	... in which the virtues of the one-armed if are extolled
16:02	technomancy	scgilardi: nice; welcome to the club.
16:02	daGrevis	yes, doseq works perfectly! thanks
16:03	technomancy	I'll have them send your club sweater to the address we have on file.
16:03	justin_smith	a one armed if framed me - now I am a Fugitive
16:03	scgilardi	:)
16:04	jeremyheiler	why is a one armed if better than when?
16:05	technomancy	jeremyheiler: it communicates intent to return a value rather than perform a side effect
16:05	jeremyheiler	ah, cool
16:05	scgilardi	so more "when is a one-armed if better than when"
16:06	technomancy	indeed
16:07	wei_	it’s more annoying to put in debugging “info” forms into if statements, but that’s a bit of an edge case
16:07	technomancy	wei_: (doto x prn) can be put nearly anywhere
16:08	wei_	ah. i always forget that doto isn’t just for java interop
16:08	technomancy	my favourite is (doto 'my.ns require in-ns) in the repl =)
16:09	wei_	lol. when do you require + in-ns over simply ns ?
16:09	technomancy	wei_: in the repl, if the ns exists on disk
16:09	justin_smith	wei_: simply ns creates the namespace without loading any of your code that goes with it
16:10	wei_	i see
16:11	wei_	just found a good alternative to my usual (ns proj.core) (load “core”)
16:20	m1dnight_	Is it possible in clojure to do something like set-cdr! ? I want to insert a variable in a list, but I need to append something to that list later on..
16:20	m1dnight_	But yeah, immutable structures and all
16:21	justin_smith	m1dnight_: not without doing evil stuff that relies on implementation details
16:21	m1dnight_	I presumed
16:21	m1dnight_	darn
16:21	justin_smith	maybe you want a finger-tree?
16:21	justin_smith	you can do things like that efficiently with immutible finger-trees
16:22	justin_smith	https://github.com/clojure/data.finger-tree
16:22	m1dnight_	looks like a good idea yes :D
16:22	m1dnight_	thanks justin_smith
16:22	justin_smith	np
16:23	m1dnight_	Porting this scheme evaluator is not as easy as I anticipated
16:23	donbonifacio	hey, I have the following coll: [ [:a 11] [:b 2]] [:c 3] ] (an array of pairs). How's a good way to get only two of them, randomly?
16:24	justin_smith	donbonifacio: would it be ok to get the same one twice?
16:24	donbonifacio	no, just once
16:24	donbonifacio	rnd-nth and sets?
16:24	justin_smith	I was just thinking that, yeah
16:24	m1dnight_	lazy seq of permuatations and random get twice?
16:25	justin_smith	a set makes sense if none of the items would appear twice
16:25	justin_smith	m1dnight_: that's O(n) for each select / remove though
16:25	m1dnight_	well, that's true
16:25	justin_smith	you can't do rand-nth on a set though
16:25	donbonifacio	humz
16:26	justin_smith	pick two random ints above -1 and below (count coll) that are not equal and get those two indexes?
16:27	Qerub	I’m writing a macro that takes a var name as an argument. How can I get access to the var inside the macro body outside of a backquote context? (defmacro m [var-name] (comment “var-name is a symbol, how do I get a var in the right namespace?“))
16:28	Qerub	find-var would have worked if var-name was fully qualified.
16:29	justin_smith	,(let [input [[:a 0] [:b 1] [:c 2] [:d 4]] places (take 2 (distinct (repeatedly #(rand-int (count input)))))] (map (vec input) places)) ; donbonifacio
16:29	clojurebot	([:a 0] [:b 1])
16:29	justin_smith	distinct ensures you don't get two identical indexes
16:29	jassa	Hi there
16:29	jassa	does anyone know what would be the best way to prevent output when running tests?
16:29	donbonifacio	thanks justin_smith :) I'll study that
16:29	nkozo	Qerub: resolve
16:30	Qerub	nkozo: Ooh, shiny. Will that resolve the symbol in the namespace of the macro invoker?
16:30	nkozo	Qerub: yes, to resolve in other namespace use ns-resolve
16:31	justin_smith	jassa: preventing output at what level? you can use nohup to prevent output of any command line invocation, or with-out-str to make a particular function scope create a string instead of printing
16:31	nkozo	Qerub: resolve is only a helper wrapping ns-resolve
16:31	justin_smith	s/function scope/lexical scope
16:31	Qerub	nkozo: So is ns bound to the namespace of the macro invoker?
16:32	cfleming	borkdude: I could do that - does REPLy do that by default?
16:32	nkozo	Qerub: I think yes, but try it, maybe I'm remembering wrong
16:32	borkdude	cfleming in the user namespace it does I think
16:32	Qerub	nkozo: Allright. Thanks a bunch!
16:32	cfleming	borkdude: There are a couple of things that are loaded by default that I do, but I can't remember the details.
16:33	borkdude	cfleming but maybe that's what happened, I wasn't in the user namespace
16:33	justin_smith	donbonifacio: regarding "studying that", likely the one trickiest thing in that code is that a vector acts as a function of index to value at that index when used as a function -- thus the redundant call to vec, since I expect it would be used in a function that may not get a vec as an argument
16:33	borkdude	cfleming so never mind then ;)
16:34	cfleming	borkdude: Right, it's clojure.main/repl-requires
16:35	cfleming	borkdude: Which includes doc and source.
16:35	donbonifacio	justin_smith: yes, thanks for the extra description :)
16:35	borkdude	cfleming cool
16:35	justin_smith	,([10 9 8 7 6] 3)
16:35	clojurebot	7
16:39	jassa	@justin_smith: I'm using lein to run my tests, and I'm trying to omit all the output from "println" statements and similars
16:39	nkozo	Qerub, but take care when calling macros from macros: https://gist.github.com/nahuel/a07db3003ad22bda17a0
16:39	jassa	justin_smith: I've tried using `with-out-str` but it returns a string where I would like to return some other data
16:41	jassa	justin_smith: I first attempted defining a log method that received a msg and would only output it if the current environment is not a testing environment.. but I couldn't find a way to determine if I'm running a test env
16:41	Qerub	nkozo: Thanks, that will probably bite me.
16:43	justin_smith	jassa: sounds like a logger configuration issue
16:44	arohner	jassa: this probably isn't helpful, but that's easy if you build your app around stuartsierra/component
16:44	justin_smith	jassa: for printlns why not just (binding [out ...] ...)
16:44	arohner	which I highly recommend anyways
16:44	justin_smith	providing some output stream that does not print
16:46	jassa	Thanks guys I'll check that out
16:55	mercwithamouth	so would you say Om isn't production ready?
16:56	mdrogalis	That ship has sailed. :)
17:10	kenrestivo	ship?
17:11	justin_smith	kenrestivo: http://en.wiktionary.org/wiki/that_ship_has_sailed
17:12	kenrestivo	i'm familiar with the idiom. i wasn't so clear on what you were referring to?
17:13	justin_smith	"I already use it in production, so it's too late to decide if it is production ready" maybe
17:13	mercwithamouth	=( someone told me it wasn't production ready...i don't see why it wouldnt be
17:14	mercwithamouth	not that i'm all that knowledgeable as of yet
17:15	dbasch	Real artists ship. The realest artists Titanic.
17:16	dbasch	“the ship can’t sink, sir. It’s as production-ready as it gets”
17:17	m1dnight_	Hmmm, I'm making another stupid mistake and I'm asking for your help, again :p
17:18	mercwithamouth	=P
17:18	m1dnight_	I have defined a deftype "Binding" in namespace meta-clojure.prototype.binding. I want to use this type in ns meta-clojure.core
17:18	m1dnight_	So I type (ns meta-clojure.core (:import [meta-clojure.prototype.binding Binding]))
17:19	m1dnight_	But that doesn't seem to work. (ClassNotFoundException)
17:19	hiredman	unless the namespace has been loaded the type hasn't been created
17:19	m1dnight_	So I tried :use, replace dash with underscore, omit "Binding",.. I can't figure it out
17:19	puredanger	how do you intend to "use" it?
17:20	puredanger	construct instances?
17:20	m1dnight_	yes, indeed
17:20	m1dnight_	example: https://www.refheap.com/91370
17:20	clojurebot	No entiendo
17:20	justin_smith	m1dnight_: require the ns, then import the type?
17:21	m1dnight_	justin_smith: then I get "unable to resolve classname Binding"
17:21	puredanger	if you require the ns, you can just use the constructor function ->Binding
17:21	Bronsa	m1dnight_: you need to require the namespace, if you don't need to test for `instance?` just use ->Binding
17:21	justin_smith	m1dnight_: you have to munge the class name for import
17:21	justin_smith	meta_clojure.prototype.binding
17:22	m1dnight_	I tried that as well, "unable to resolve classname" :p
17:22	m1dnight_	But in the namespace itself I can just cal (Binding. "foo" "bar"), so shouldn't that work as well in the core namesapce?
17:22	m1dnight_	namespace*
17:23	m1dnight_	(:require [meta_clojure.prototype.binding]) # This is what's required at the moment. I thought that should work.
17:23	Bronsa	m1dnight_: (ns .. (:require [meta-clojure.prototype.binding :refer [->Binding]])) or (ns .. (:require meta-clojure.prototype.binding) (:import meta_clojure.prototype.binding.Binding)) should do it
17:23	puredanger	deftypes have the dual nature of Clojure construct and Java class implementing the Clojure construct. generally I prefer to treat it as a Clojure construct as much as possible, so would use ->Binding rather than import and Binding.
17:23	ed-g	hello, does anyone know how to define a composite primary key in Korma?
17:24	m1dnight_	well the latter did the trick Bronsa
17:24	Bronsa	I sometime wish deftype generated an instance check predicate too
17:24	m1dnight_	require and import
17:25	puredanger	Bronsa: +1
17:25	m1dnight_	(inc Bronsa) ; Am I doing this right? :p
17:25	lazybot	⇒ 57
17:25	m1dnight_	It's confusing though, the namespace stuff. Regular functions only require a :use or :import, but deftype requires require and import.
17:25	m1dnight_	(I'm blaming me, though)
17:26	puredanger	Bronsa: btw, I suspect there may be questions re the great jira shuffling, if so let me know
17:27	Bronsa	m1dnight_: forget about :use, it's only :require and :import. functions only need :require, java classes need :import. deftypes need their containing namespaces to be :required too so that the classes actually get compiled
17:27	justin_smith	m1dnight_: import is never needed, it's a convenience so you don't have to type out the full package with the class
17:27	m1dnight_	Oh, let me try something, brb
17:28	Bronsa	puredanger: sure :)
17:28	m1dnight_	Oh indeed, require loads the namespace, and then I can identify Binding with (meta_clojure.prototype.binding.Binding. ..)
17:29	m1dnight_	so import is as you said justin_smith , for convenience's sake
17:29	Qerub	nkozo: Here’s what I needed `resolve` for earlier: https://gist.github.com/qerub/216a7945831a30ed0d63#file-fancy-defn-clj-L24 (proof of concept of schema.core.defn augmented with automatically generated clojure.core.typed annotations via circle.schema-typer, phew)
17:29	puredanger	Bronsa: the general gist is people are actively using or wanting to use transducers in production so we pushed almost everything not yet done into 1.8 and plan to drive with haste towards 1.7, which will primarily be transducers + possibly feature expressions
17:29	Bronsa	puredanger: there were tears of joy shed by many earlier today when CLJ-1297 got applied
17:29	Bronsa	puredanger: yeah guessed as much
17:29	puredanger	you're welcome :)
17:30	puredanger	many battles were fought today :)
17:30	puredanger	one thing that would be great to have more wider feedback on is http://dev.clojure.org/jira/browse/CLJ-1529
17:31	mdrogalis	puredanger: That's really nice to hear - about 1.7 :)
17:31	puredanger	Rich would really like to do something re the compilation speed there. I have resurrected a subset of fastload with his prior work into a second patch there.
17:31	justin_smith	cfleming: I wonder if the racket folks are imitating you here https://twitter.com/racketlang/status/519565183937970176
17:32	puredanger	I am currently running some tests on various projects to compare perf differences. may also need to address the semantic differences if Zach's is faster (which seems likely atm)
17:32	puredanger	would love to hear feedback on those from private code bases
17:33	mdrogalis	I'll give it a whirl
17:34	puredanger	question 1 is whether class-for-name.diff yields any compilation problems or errors as it has a semantic change (I think this is unlikely based on my own research so far) and 2 - what is perf improvement from either
17:34	cfleming	justin_smith: Ha, nice - I doubt I can claim that they're copying me, but that looks great
17:35	ztellman	puredanger: I feel like there would have been a bug report if someone stumbled across the current semantics
17:35	ztellman	it's such a weird precedence
17:35	puredanger	agreed, I think it's unlikely
17:35	puredanger	and I've run with this patch on a bunch of projects
17:35	Bronsa	uhm, so, other than . also catch and new currently privilege classes over locals
17:36	Bronsa	should they get handled aswell if ztellman's patch gets accepted?
17:36	puredanger	that is the other question to figure out - where does this change semantics and how and what needs to change
17:36	ztellman	Bronsa: currently let-bound variables that share names with classes are shadowed by the classes
17:36	hiredman	well, they don't privilege right? new and catch must have classes
17:36	cfleming	puredanger: what is the status of feature expressions? I saw the design doc had been updated.
17:36	Bronsa	,(let [String 1] (String. ""))
17:36	clojurebot	""
17:37	hiredman	. could get a class or local
17:37	ztellman	unless you have code that looks like (catch Exception String ...)
17:37	Bronsa	hiredman: yeah I guess you're right
17:37	ztellman	it doesn't affect you
17:37	cfleming	puredanger: I'll see if I can find some time to compile Cursive with that patch and see if it helps
17:39	puredanger	cfleming: that page has current state of work although I was told the many ways it should be improved today :) in essence, the path is to use same syntax as .cljx but to build that into Clojure and ClojureScript
17:39	cfleming	puredanger: Ok, are you going to be updating that soon? I'd be interested in knowing what I'm in for.
17:40	puredanger	yes
17:40	puredanger	1.7 remaining work is now down to http://dev.clojure.org/jira/secure/IssueNavigator.jspa?mode=hide&requestId=10519
17:40	puredanger	so that's my current focus
17:40	cfleming	puredanger Bronsa: Tears of joy were also shed by me when 1330 was merged in.
17:41	Bronsa	puredanger: oh by the way, there are a bunch of tickets that are "completed" but not "closed", that hurts my feelings. Mind if I close them?
17:41	puredanger	example?
17:41	Bronsa	"resolved" actually
17:41	Bronsa	http://dev.clojure.org/jira/secure/IssueNavigator.jspa?reset=true&jqlQuery=project+=+CLJ+AND+fixVersion+=+"Release+1.7"+AND+status+=+Resolved+ORDER+BY+priority+DESC&mode=hide
17:42	Bronsa	cfleming: :P
17:42	puredanger	cfleming: you were no small reason for 1330 going in, so thanks on that
17:42	puredanger	Bronsa: I'll take care of them
17:42	Bronsa	puredanger: cool
17:43	cfleming	puredanger: What's the use case for user-defined feature expressions?
17:44	puredanger	many examples floating around. one would be specializing something in cljs for node
17:44	cfleming	puredanger: And am I reading that correctly that I could do #+(cljs and node) ?
17:44	puredanger	yes
17:45	cfleming	puredanger: Damn
17:45	puredanger	I get that a lot
17:45	cfleming	puredanger: I suspect it's usually more appreciative than that one was ;)
17:45	Bronsa	(inc puredanger)
17:45	lazybot	⇒ 16
17:46	puredanger	I'm glad it was appreciative :)
17:46	cfleming	puredanger: Supporting that is going to be... interesting.
17:46	puredanger	there are patches out there for clj, tools.reader, cljs that do most of what's on the page
17:48	cfleming	puredanger: So I could construct a frankenclojure with those features now to test with?
17:49	puredanger	yep. I have done so and rebuilt some mixed clj/cljs projects with them (instead of clix) with some success
17:50	cfleming	puredanger: Ugh, I should have read that page more recently - I read it ages ago when it was just an RFC really
17:50	cfleming	puredanger: Supporting debugging with this is going to be hard.
17:51	puredanger	yes, it presents some difficulties.
17:52	cfleming	puredanger: Is there an ETA? Sounds like soon, right?
17:53	puredanger	I'll be working on it tomorrow. gotta run atm…
17:53	cfleming	puredanger: I meant for the final release - no worries, I won't have time to work on this for a while anyway.
17:55	puredanger	yes, soon as it's done OR if there are unresolvable issues then will get kicked out of 1.7
17:56	nkozo	core.async question: (def c (chan)) (go (<! c) (println :hi)) (def c nil) .. now nothing is referencing the channel, will GC trigger a channel close so the go loop will continue execution?
17:56	nkozo	or both the chan and the go-block will be GC'ed without continuing the execution?
17:57	hiredman	I may be wrong, but I am pretty sure the go block is referencing the channel
17:57	nkozo	hiredman: in that case, who is referencing the go block?
17:58	hiredman	nkozo: for informal reasoning purposes just assume a go block is a gc root like a thread
17:59	hiredman	(the go block when parked needs be put somewhere with some information about what it is parked awaiting for)
17:59	nkozo	hiredman: so my sample will leak memory?
18:00	hiredman	nkozo: if you spin up a thread trying to pull something from a queue you never put anything in, is that leaking memory?
18:02	nkozo	hiredman: ok, I had a misconception where go-blocks are referenced from the channels they are parking on, so GC'ing the channel will GC the go block
18:03	hiredman	nkozo: I suppose that could be the case
18:03	nkozo	hiredman: thanks
18:07	hiredman	you may be right, so that is an interesting question, I doubt the channel is closed before it is gc'ed
18:10	m1dnight_	aw yisss, evaluation of defines and primitives works!
18:10	m1dnight_	time to go to bed :D
18:13	m1dnight_	only downside, I have implemented my own linkedlist such that I can modify an environment
18:13	m1dnight_	There probably is a pure functional way but I can't think of one with a fried brain atm
18:15	justin_smith	m1dnight_: if you want a mutable list with easy insert and setcdr, why not java.util.LinkedList?
18:16	justin_smith	oh wait, maybe java.util.LinkedList doesn't have a setcdr
18:16	m1dnight_	well, I wanted to stay away from java for.. some reason
18:17	m1dnight_	I did get to know deftype and definterface though
18:17	m1dnight_	so not all was in vain
18:20	gfredericks	m1dnight_: writing a lisp or something?
18:27	m1dnight_	gfredericks: yes, I need to build a prototype for my thesis to test combination of actor model (which i also implemented) and STM (for which I have a meta implementation)
18:27	m1dnight_	Since the software lab at my uni is a fan of scheme I decided to implement a simple scheme IDE
18:28	m1dnight_	and no IDE without evaluation, so i'm quickly mashing up an evaluator
18:29	m1dnight_	And the source code would be an an STM storage and the evaluator, syntax checker, parenthesis balancer etc would be actors acting on that STM
18:31	gfredericks	HUH.
18:31	gfredericks	actors with shared memory is not an oxymoron?
18:33	justin_smith	gfredericks: wouldn't the shared or unshared status of the memory be just an implementation detail? now if your actor system mutated the messages,then you aren't doing actors...
18:34	m1dnight_	gfredericks: that is the entire point. Study how we can combine them safely without violating constraints of either model.
18:35	gfredericks	I assumed "acting on that STM" was something like a bunch of clojure threads punching some refs
18:35	gfredericks	rather than passing messages
18:35	m1dnight_	If there were to be violations (e.g., sending a message in a transaction resulting in multiple sends to an actor), how to mitigate them
18:35	m1dnight_	exactly what you say :)
18:36	m1dnight_	clojure threads being actors in this case
18:36	tuft	actors in a more abstract sense it sounds like vs erlang's or something
18:36	m1dnight_	But if I were to hold message sends back until the transactino completes, i would solve that problem.
18:36	m1dnight_	no I'm sticking to the vanilla actor model, except he locality semantics
18:36	m1dnight_	the*
18:38	m1dnight_	but I'm starting off with a meta-implementation for actors and STM. This way I can combine them both and add/remove semantics
18:38	justin_smith	m1dnight_: I often do that "transactino" typo - we should get Bronsa to make a "super lightweight stm" lib, where all the vars are named in Italian, and transactions are replaced by transactinos
18:39	m1dnight_	:D :D :D
18:39	m1dnight_	anyway, i'm off to bed
18:39	m1dnight_	tomorrow is thesis-day!
18:39	m1dnight_	nn guys o/
18:50	AeroNotix	is there a library/function that can turn a state change into a channel read? I want to alt on a timeout and a state update
18:59	brainproxy	hmm, been awhile since I upgraded my cider/emacs stuff... when I try to do cider-connect, I can enter the host but then it wanders off into trying to do some tramp/ssh thing
18:59	brainproxy	there
18:59	brainproxy	which is not what I want... I'd like to just spec the port and make a direct connection
19:03	nwolfe	brainproxy: so you don't want to cider-jack-in then?
19:09	brainproxy	I think I just want cider-connect
19:09	brainproxy	the repl is running on an external host
19:09	brainproxy	on port 7888
19:10	nwolfe	Ah, just making sure. Not familiar enough with cider-connect to help
19:10	justin_smith	brainproxy: I hope this is on a locked down lan that you don't share btw
19:11	brainproxy	justin_smith: yes, sure, it's in a dev env on my laptop consisting of various layers of vagrant and docker
19:14	brainproxy	I'm experiencing what's described here: https://github.com/clojure-emacs/cider/issues/822
19:14	brainproxy	but it seems like it should have been solved...
19:19	dbasch	“A clojure library designed to… well, that part is up to you” http://goo.gl/ezp9zi
19:19	dbasch	56k results
19:19	gfredericks	okay I'm gonna figure out a way to suppress leiningen's tools.nrepl dependency
19:19	gfredericks	I'm thinking a leiningen middleware at worst right?
19:20	gfredericks	gonna need to make a library called lein-nrepl-suppressor
19:20	technomancy	gfredericks: remove it entirely, instead of replace it?
19:21	gfredericks	well I want to replace it by a dep with a different group name
19:21	gfredericks	so depends on your perspective I guess
19:21	technomancy	oh, I see
19:23	noonian	gfredericks: i've only gotten that to work by building it yourself and linking your lein script to it
19:23	gfredericks	noonian: building what?
19:23	noonian	leiningen
19:23	gfredericks	noonian: do you know why a middleware wouldn't work?
19:25	noonian	gfredericks: not specifically but i didn't go that far before giving up and I was pretty new to clojure at the time, what would the middleware do exactly? dynamically modify the classpath?
19:27	gfredericks	noonian: middleware can arbitrarily edit the project map, so I assume just fish around for the nrepl dep under :dependencies and remove it
19:27	technomancy	gfredericks: the problem there is if you mash the project map directly it doesn't survive a re-merge of profiles
19:28	noonian	gfredericks: that would probably work. thinking back I think my problem was harder because i wanted to use the new version of tools.cli in a leiningen plugin so that was running inside the leiningen process
19:29	gfredericks	technomancy: oh man what on earth? why? huh?
19:29	gfredericks	re-merge??
19:29	lazybot	gfredericks: What are you, crazy? Of course not!
19:30	technomancy	gfredericks: consider this... if you merge the default profiles into a project map, how do you un-merge them if you realize later you need a different set of profiles?
19:30	visof	what is the best way to create map with value as a list and each time append to this list, as example, i need to collection all 4 and 3 length words from text, and the result should be {:four [....] :three [....]}
19:30	visof	what is the best way to this
19:30	visof	?
19:30	technomancy	if you can solve that in a way that isn't "keep the original project map around as metadata and merge the new profiles into that instead" please let me know and we will use it for lein 3
19:30	noonian	visof: update-in
19:31	noonian	might be off, one sec
19:31	noonian	,(update-in {:foo []} [:foo] conj "bar")
19:31	clojurebot	{:foo ["bar"]}
19:31	gfredericks	technomancy: okay so if I mash both the project map and its metadata then...nevermind
19:32	gfredericks	technomancy: I'll dig as deep as I need to into this and let you know what I come up with :)
19:32	technomancy	gfredericks: yeah, that would do it. it's just ... un-ideal
19:33	technomancy	gfredericks: my quip earlier about "Leiningen: the Good Parts" was partly about this specific misfeature
19:52	noonian	technomancy: the atreus looks sweet btw! i randomly caught your emacs chat thing with sasha chua when i was looking into org-mode and your workshop inspired me to get an ergodox :P
19:52	technomancy	noonian: thanks =)
19:52	technomancy	I forget, did she link to http://atreus.technomancy.us?
19:53	gfredericks	technomancy: but it's not the original project map that has tools.nrepl, it's the base profile, amirite?
19:53	Cr8	I got an ergodox - but those tiny diodes man
19:53	Cr8	still working on it =P
19:53	noonian	i don't think so, that was months ago and i just now saw the atreus (i think someone linked to it from redit)
19:54	technomancy	noonian: cool, on r/mechanicalkeyboards?
19:54	noonian	yeah, i ordered the most recent kit on massdrop so i'm learning to sodder and collecting tools now heh
19:54	noonian	technomancy: yeah in response to someones ergodox pics i think
19:54	noonian	the comments i mean
19:54	technomancy	gfredericks: well, profiles are looked up in the project map
19:55	gfredericks	well I can't just remove :base
19:55	gfredericks	do the full profiles get nested in there first?
19:55	technomancy	gfredericks: I think you need to reach into :profiles and possibly :profiles on metadata too, but I'm super fuzzy on this
19:56	gfredericks	I imagine if I examined how with-profile is implemented I would understand all the pieces involved?
19:56	technomancy	you'll want to explore in a repl
19:57	gfredericks	clojurebot: you'll \|want\| to explore in a repl
19:57	clojurebot	Ack. Ack.
19:57	technomancy	words to live by
19:57	technomancy	noonian: do you have a link to the thread?
19:58	_pr0t0type_	Hey guys, how do I correctly route a directory (with static assets) correctly using Ring?
19:58	_pr0t0type_	I'm tried: (GET "/styles" [] (resp/resource-response "app/styles" {:root "public"}))
19:58	_pr0t0type_	doesn't work
19:59	noonian	technomancy: i'll check my history it was like yesterday but gimme a sec i'm at work
20:02	justin_smith	_pr0t0type_: what is the relative path of the resource directory in your project?
20:04	_pr0t0type_	justin_smith: its a leiningen project (lein new compojure) which serves all static assests out of the {project_root}/resource/public/ path
20:04	justin_smith	resource or resources?
20:05	_pr0t0type_	resources
20:05	_pr0t0type_	sorry
20:05	_pr0t0type_	if I try to route a specific file (ie index.html) it works just fine
20:05	_pr0t0type_	but I can't make it work with
20:05	_pr0t0type_	dirs for some reason
20:05	_pr0t0type_	for instance, this works:
20:05	_pr0t0type_	(GET "/" [] (resp/resource-response "app/" {:root "public"}))
20:05	_pr0t0type_	sorry, I mean
20:05	_pr0t0type_	(GET "/" [] (resp/resource-response "app/index.html" {:root "public"}))
20:06	_pr0t0type_	works
20:07	justin_smith	the right way to do this, if you have a directory of static resources, is not to define a route, but to use wrap-resources
20:07	justin_smith	resource-response is to define one endpoint, wrap-resources is to define an endpoint for each resource under that path
20:08	_pr0t0type_	I see
20:08	justin_smith	wrap-resources is a middleware that gets applied to your handler
20:08	justin_smith	sorry, not wrap-resources, but wrap-resource
20:08	_pr0t0type_	Let see if this worksl Can I thread it via the (defroutes) call?
20:08	justin_smith	https://github.com/mmcgrana/ring/wiki/Static-Resources
20:09	_pr0t0type_	ie
20:09	_pr0t0type_	(-> (defroutes app-routes …) (wrap-resource))
20:09	_pr0t0type_	lets see...
20:09	justin_smith	yeah, except wrap-resources also take a base directory argument (likely "public"
20:09	justin_smith	)
20:10	_pr0t0type_	gotcha
20:11	noonian	technomancy: i'm sorry i can't seem to find it. it might not have been in a reddit thread afterall
20:11	_pr0t0type_	Yes!
20:11	_pr0t0type_	justin_smith: it worked, thanks dude
20:11	justin_smith	np
20:11	_pr0t0type_	(def app
20:11	justin_smith	usually works for me :)
20:11	_pr0t0type_	:)
20:12	technomancy	noonian: no worries
20:54	gfredericks	technomancy: actually I might just use :injections to monkey-patch my nrepl changes and not worry about it
21:01	iamdustan	Luyt_: nah. I’ve abandoned codeeval for exercism.io
21:15	brainproxy	Raynes: is laser dead/dying?
21:16	Raynes	brainproxy: I don't currently have time to work on it, enlive is being maintained again (AFAIK), and almost nobody used laser in the first place.
21:16	brainproxy	Raynes: gotcha, thanks for the quick feedback
21:17	Raynes	If somebody wanted to work on it, they're totally welcome to. But I have little incentive to when I'm the only person using it :P
21:17	brainproxy	looks like cgrand has something new-ish cooking w/ enliven?
21:17	brainproxy	though looks like enlive has been updated more recently than enliven
21:34	gfredericks	this whidbey plugin seems to think that a profile called :repl is used whenever you run `lein repl`; but that does not happen for me
21:34	gfredericks	anybody know if that's supposed to happen?
21:38	jeremyheiler	gfredericks: the readme seems to show the repl profile as an example
21:38	jeremyheiler	of putting your stuff in a diff profile, not as if the repl profile is already there
21:39	gfredericks	jeremyheiler: it does it internally too
21:39	jeremyheiler	hmm
21:39	gfredericks	if I use the plugin in the basic fashion, it does nothing for `lein repl` but does for `lein with-profile +repl repl`
21:39	jeremyheiler	oh i see
21:40	gfredericks	independently I can't figure out how it expects to work as a middleware alongside the builtin pr-str middleware
21:40	gfredericks	right now I'm actually seeing the incorrect behavior of having both of them running at once
21:41	gfredericks	either I see a string literal with pretty-printed data inside it, or a trivially-pretty-printed string of data (depending on what order the two go in), and I've seen both
21:41	gfredericks	I also saw it work correctly a few weeks back but have no idea how to reproduce that
21:44	gfredericks	oh nevermind I see what it does
21:44	gfredericks	it's right after the "Here's where things get ugly" comment :)
21:46	jeremyheiler	heh, i was just looking at that part
21:47	jeremyheiler	still, it expliclitly alters the repl profile
21:47	gfredericks	sure, my original question is whether I should expect the repl profile to be active for the repl command
21:48	jeremyheiler	ah
21:49	arrdem	AFAIK it is
21:49	arrdem	cider does `lein repl :user` tho..
21:49	gfredericks	yeah?
21:49	gfredericks	well still I'm not using cider in this instance
21:50	arrdem	just a thought
21:50	jeremyheiler	i dont' think repl is a built in profile, if that's what you mean
21:56	jeremyheiler	ok, it is there. so... why isn't it active then? hmm
21:56	gfredericks	what's there?
21:56	gfredericks	in the repl task?
21:57	jeremyheiler	yeah
21:57	jeremyheiler	https://github.com/technomancy/leiningen/blob/master/src/leiningen/repl.clj#L285
21:57	gfredericks	I'm getting the same behavior on another machine
21:57	jeremyheiler	i treid it and got the same too
21:58	gfredericks	phew
21:59	gfredericks	well I think I have to declare defeat right there for the evening and pick up being defeated some other day
21:59	jeremyheiler	heh.
22:00	gfredericks	jeremyheiler: thanks for poking around
22:00	jeremyheiler	it was fun
22:05	cfleming	gfredericks jeremyheiler: I feel a bit better after reading this, the lein profile system never fails to make me feel dumb when I try to figure out how it works.
22:09	jeremyheiler	heh! i like it conceptually, tho
22:10	cfleming	jeremyheiler: Sure, in theory it's quite simple, but you know what they say about theory and practise
22:11	pdk	is it that they say to spell practice with a c
22:12	jeremyheiler	cfleming: yeah, you get things like !important :-P
22:13	cfleming	pdk: They could start with that, yes
22:34	technomancy	gfredericks: :repl not getting loaded might be a 2.5.0 bug
22:53	danielcompton	amalloy: flatland/useful doesn't accept github issues. Should I put one on amalloy/useful?
22:54	amalloy	danielcompton: yeah, i suppose so. i wish flatland were still the primary, but then my user profile looks like i never do anything
22:55	danielcompton	amalloy: because 'popular repositories' only shows ones you own?
22:55	arrdem	amalloy: I think they fixed that... I'm totally getting credit for shit done on the grimoire group
22:55	danielcompton	amalloy: you would get to 'contribute' to your own repo :)
22:58	cddr	If I add an explicit System/exit as the last line of a lein plugin, it causes the task to exit much more quickly. Does anyone have any idea why that would be?
22:59	arrdem	cddr: waiting for threads to exit usually
23:03	devn	,shutdown-agents
23:03	clojurebot	#<core$shutdown_agents clojure.core$shutdown_agents@182cbe9>
23:03	devn	,(shutdown-agents)
23:03	clojurebot	#<AccessControlException java.security.AccessControlException: access denied (java.lang.RuntimePermission modifyThread)>
23:04	devn	,(doc shutdown-agents)
23:04	clojurebot	"([]); Initiates a shutdown of the thread pools that back the agent system. Running actions will complete, but no new actions will be accepted"
23:06	cddr	Interesting. Thanks!
23:12	justin_smith	arrdem: wait, he was asking why the Shutdown caused it to exit sooner, not why it would hang and not shut down...
23:15	cddr	It hangs for about 20seconds before eventually shutting down. I replaced the System/exit with a line printing the number of running threads and get 5 so that does seem to be plausible.
23:16	justin_smith	oh, OK, I misunderstood the discussion, clearly
23:18	cddr	Nah I'm just bad at IRC.
23:18	caar	damn how is this not taken
23:21	justin_smith	you would think some crusty old lisper would have taken that one
23:22	arrdem	that's what I was expecting...
23:23	arrdem	although having more than two c[ad]*r in one channel would probably be silly
23:24	justin_smith	talk to the caaar because the cadar ain't listenin honey
23:25	justin_smith	actually that didn't make any sense at all, apologies
23:30	zanes	Why when I add [plumbing.core :refer [map-vals]] do I get the warning, WARNING: update already refers to: #'clojure.core/update in namespace: plumbing.core, being replaced by: #'plumbing.core/update?
23:30	zanes	I didn’t refer ‘update’.
23:30	zanes	Why is it mad?
23:31	arrdem	zanes: plumbing is defining plumbing.core/update, which shadows clojure.core/update in the namespace plumbing.core
23:31	justin_smith	you automatically refer clojure.core
23:31	arrdem	zanes: it's just a warning. you're ok
23:31	justin_smith	you can use (:refer-clojure :exclude [update]) in your ns decl to fix this
23:31	zanes	Oh! So it’s Prismatic’s fault?
23:31	arrdem	zanes: yep
23:32	zanes	They didn’t :refer-clojure :exclude [update]?
23:32	zanes	I see.
23:32	zanes	That’s irritating.
23:32	arrdem	zanes: bingo
23:32	arrdem	zanes: see if there's a ticket open :P
23:32	justin_smith	oh, they would need to do the :exclude
23:32	justin_smith	update is a recent function right?
23:32	justin_smith	(doc update)
23:32	clojurebot	"([m k f] [m k f x] [m k f x y] [m k f x y ...] [m k f x y ...]); 'Updates' a value in an associative structure, where k is a key and f is a function that will take the old value and any supplied args and return the new value, and returns a new structure. If the key does not exist, nil is passed as the old value."
23:32	zanes	I guess this is what I get for using the 1.7.0 beta.
23:32	arrdem	justin_smith: yeah
23:32	justin_smith	it could be newer than prismatic
23:32	arrdem	justin_smith: it's new in 1.7
23:32	zanes	Yeah.
23:32	zanes	I bet they’re still on 1.6.x.
23:32	jeremyheiler	oh nice, finally getting update!
23:32	zanes	Never mind. My anger is misplaced.

23:36	aconbere	do I need to load the goog library?

23:38	aconbere	(I'm trying to compile currently with the set of options they call "release")
