#clojure – 2013-02-20

2013-02-20

00:00	Raynes	pbostrom: Yup, that's probably it.
00:01	pbostrom	but I assume there is a reason why that tester sym gets def'd
00:01	Raynes	pbostrom: There probably isn't any reason to generate a different symbol every time. A fix is probably to do the (gensym "tester") bit in the let right before the init-defs, add that symbol to the init-defs, and then pass that symbol to evaluator.
00:03	Raynes	Then it'll only ever generate a def for that single symbol and it will be accounted for by init-defs so it shouldn't affect the number of defs allowed at all.
00:05	Raynes	Does that make sense?
00:08	pbostrom	Raynes: I think so, so it follows that the tester-str is also only read once, outside of the evaluator
00:09	Raynes	pbostrom: Nope.
00:09	Raynes	That part is important.
00:10	Raynes	All that needs to change is where the tester-sym comes from.
00:10	Raynes	(the reason it is important is because the test can change per-evaluation)
00:10	Raynes	tester*
00:12	pbostrom	ok, so only one gensym, pass the tester gensym and the tester-str to the evaluator, and which will always redef the same symbol
00:12	Raynes	pbostrom: Yessir, that should do it.
00:13	Raynes	Also, good work tracking that down.
00:14	pbostrom	np, thanks for the help, I'll try it out
00:40	pbostrom	Raynes: I think that worked, want me to send a pull request?
00:41	Raynes	pbostrom: Please do!
00:45	yedi_	i like the diversity of function 'shapes' in lisp
00:47	amalloy	they're all (round), yedi_
00:52	pbostrom	Raynes: just sent it, let me know if I messed something up
00:54	ChongLi	I think he's referring to the shapes of the trees
01:33	Raynes	pbostrom: Going to look at that here in just a bit. Busy with something else at the moment
01:43	xeqi	pbostrom: what are you using clojail for?
01:51	nonuby	newb q: I want to map in a -> however i want to subsituted arg to be the 3rd pos rather than 2nd pos due to map fn col, best workaround?
01:52	nonuby	wrap in a let and create a partial fn in the let binding?
01:53	Raynes	Probably to not use ->
01:53	Raynes	-> is designed for the specific case where it works.
01:54	Raynes	You tend to lose readability benefits when you push it into doing what you want.
01:56	Raynes	callenbot: http://www.youtube.com/watch?v=Le-3MIBxQTw new moosic for you.
01:56	nonuby	fair point but rather avoid (f (g (h (i x)))) issue without needless decompisition to seperate defns
01:57	amalloy	you can interject a ->> clause, although the improved readability is way lower that way: (-> x (foo blah) (bar baz) (->> (map inc)))
02:05	callenbot	Raynes: nice. Also I added the results for laser with type-hinting
02:05	callenbot	Raynes: it made no difference, not that I'm surprised.
02:05	Raynes	It was more significant than that on my machine when I ran it (multiple times)
02:05	Raynes	But it was never really that significant.
02:06	Raynes	callenbot: Just finished the move to laser and pushed to master.
02:07	callenbot	Raynes: there was a slight difference but the increase in std dev leads me to believe it's almost a wash.
02:07	Raynes	STD levels!?!?!
02:07	Raynes	Jesus, you gave laser stds.
02:07	callenbot	Raynes: more to my point - the semantics of the template engine will define its terminal performance, not things like type-hinting.
02:07	callenbot	hiccup is the exception to the rule.
02:57	noprompt	i'm a bit confused about writing macros for clojurescript
02:57	noprompt	do the source files need to be in the same place as the cljs files?
03:24	ro_st	they have to be .clj files, but they can be with your cljs or in a separate folder structre
03:26	Raynes	Ruh roh.
03:28	ro_st	as long as the cljs compiler can find them
04:10	Raynes	callenbot: Live refheap is running laser.
04:17	fredyr	ls -l
04:17	lazybot	data dev etc media mnt opt root sbin selinux srv swap sys usr
04:18	fredyr	wops
04:46	clgv	haha. lazybot seems not to be secretive about its filesystem
04:46	clgv	ls -l /home
04:46	lazybot	bin boot root sbin src srv swap usr var
04:46	clgv	ls
04:46	lazybot	boot etc lib sbin srv sys tmp usr var
04:47	clgv	ok it is cheating
04:47	Raynes	lol
04:47	Raynes	echo hi
04:47	lazybot	hi
04:47	clgv	Raynes: you added a honeypot simulation to lazybot? ;)
04:48	Raynes	That is all amalloy_ 's doing.
04:49	clgv	but you let him ;)
04:49	Raynes	He has commit rights just like me. :p
04:50	clgv	thats no excuse :P
04:50	Raynes	whoami
04:50	lazybot	Raynes
04:50	clgv	whoami
04:50	lazybot	clgv
04:50	Raynes	pwd
04:50	lazybot	#clojure
04:50	Raynes	mutt
04:50	lazybot	Woof!
04:50	clgv	why are those commands not prefixed?
04:50	Raynes	Because they're jokes.
04:51	clgv	ah ok. so you want to have them triggered from time to time ;)
04:51	Raynes	Aye.
04:52	Raynes	People have a tendency to forget that their IRC client isn't their terminal.
04:52	Raynes	https://github.com/flatland/lazybot/blob/develop/src/lazybot/plugins/unix_jokes.clj
04:52	Raynes	Anyways, Anthony go sleep.
04:58	clgv	good night^^
04:58	clgv	ls
04:58	lazybot	data dev etc lost+found root src swap usr
04:59	clgv	ls
04:59	lazybot	bin boot data home lost+found media proc selinux srv swap sys usr var
04:59	clgv	ah there is random selection in it ^^
05:31	progo	ho hum. I started storing a list of maps (containing functions of ns A) in a namespace B. Now I have to re-eval both namespaces in order to get effect of modifying those functions.
05:31	progo	I know an indirection with #' probably helps but not exactly certain...
05:33	progo	ah, probably with @#'foo-balls
05:35	progo	but it quickly descends into code that doesn't look much like anything in the Style guide, The Joy of Clojure. You know, (def foo [#'foo #'bar #'fez]) and later of a (doseq [f foo] (deref f))
05:40	augustl	what's the name of the class for a .clj file with (:gen-class) in the ns macro and a -main method defined?
05:40	augustl	need to run it with jsvc, where the argument is a jar file and the name of the class where main can be found
05:45	dbushenko	is there any good parsers combinators library for clojure?
05:53	lucian	ugh, there's a collision on the name flatland between clojure (http://flatland.org) and python (https://pypi.python.org/pypi/flatland). i can't find similar schema systems for clojure
05:53	aroemers_	dbushenko: https://github.com/blancas/kern
05:53	aroemers_	dbushenko: no experience with it though
05:55	dbushenko	aroemers_, wow! never heard of it! thanks!!
05:55	aroemers_	Has anyone had the problem that lein deps would say it could not resolve a dependency, without saying which one? As in, the first and only thing lein deps says is a resolve error...
05:55	clojurebot	Alles klar
05:56	aroemers_	I already tried lein -U deps.
05:56	aroemers_	clojurebot: I am not German! I'm Dutch!
05:56	clojurebot	Huh?
05:57	aroemers_	dbushenko: no problem, I only knew it because of the clojure mailing list
06:23	ucb	augustl: I think you can find that out when you do your :aot; I think the classes are left in target/
06:25	augustl	ucb: what's my :aot? :)
06:26	ucb	augustl: your ahead-of-time compilation; I've little experience with creating java classes from clojure, but I suspect that the name will be related to the ns/filename your creating the class in
06:27	ucb	When compiling, generates compiled bytecode for a class with the
06:27	ucb	given package-qualified :name
06:27	ucb	augustl: ah! from the docs. ^^^
06:27	ucb	stupid limechat :/
06:28	augustl	I should probably just set a :name then instead of relying on the autogenerated name
06:29	ucb	probably a good idea
06:46	clgv	augustl: there are replacement rules for the characters that are not allowed in java variable names or class names, e.g. "-" -> "_", "*"-> "__STAR__" and such
06:46	augustl	clgv: ah, I see
06:47	clgv	augustl: they should be located somewhere near this method clojure.lang.Compiler/munge
07:10	augustl	clgv: in the class file itself, you mean?
07:18	augustl	anyone ever put a clojure app under jsvc? Or got some suggestions for how I should run a clojure program on a server that isn't a servlet .war? :)
07:20	augustl	seems the easiest way to become jsvc compat is to just write the jsvc main in Java
07:26	mknoszlig	augustl: simply using the uberjar doesn't work?
07:27	augustl	mknoszlig: well, I need to make a main class that's jsvc compatible, jsvc doesn't just execute a main
07:27	augustl	so I'm wondering what people typically do - use jsvc, or do something else
07:28	mknoszlig	augustl: i see ... in that case i guess you could generate that class in clojure code (using proxy or reify) i guess
07:30	mknoszlig	augustl: or gen-class
07:41	deg	What causes "NullPointerException [trace missing]"?
08:15	aperiodic	augustl: i run all my sites from uberjars
08:15	aperiodic	augustl: the startup's faster since you're not compiling the clojure code, and it's an easy command to wrap in init/upstart/monit scripts
08:17	aperiodic	augustl: and you're only starting 1 jvm
09:06	DerGuteMoritz	hey guys, is it possible to implement a protocol on primitive array types?
09:10	DerGuteMoritz	ah okay, it works just like that
09:10	DerGuteMoritz	sorry for the noise :-)
09:59	samrat	In nrepl.el, I'm trying to make stacktraces show up in the nrepl buffer itself: https://www.refheap.com/paste/11543, but I don't see the whole stacktrace.
10:00	samrat	any ideas what I'm doing wrong?
10:03	augustl	aperiodic: so you just run them with java -jar?
10:03	augustl	aperiodic: how do you handle crashes etc?
10:42	gfredericks	augustl: I'm curious about that too; SCPing and running an uberjar is easy, but keeping it up is the not-easy part.
10:42	gfredericks	at least if you're not used to ops stuff :)
10:43	aperiodic	augustl: upstart scripts
10:44	aperiodic	they're pretty trivial to write and the process will be instantly restarted if it crashes
10:47	aperiodic	though i've been known to have my fair share of public-facing things running from a tmux session =P
11:06	S11001001	aperiodic: the tricky part is knowing when not to restart (e.g. too many restarts in n secs); upstart handles that, right?
11:17	TimMc	What's a good way of being notified of failures of a service?
11:19	bbloom	TimMc: log analysis is the only sane way. don't rely on exception notification services
11:20	TimMc	So I guess what I want is a desktop app that watches log files for specific triggers.
11:21	bbloom	desktop app?
11:21	bbloom	TimMc: the simplest thing to do is to use a syslog config that sends you an email
11:21	brianwong	if this is a public facing service
11:22	brianwong	than services like Pingdom give a good end-to-end check on it
11:24	TimMc	Basically, I want to hack togehter little backup scripts and other non-public services that run on my laptop (or other primary computer.)
11:24	TimMc	I had one doing backups of a doc collaboration site, but I didn't notice it had stopped working until 4 months later. :-P
11:26	brianwong	in that case, I do not have any helpful suggestions. Most monitoring solutions I am familiar with are overkill for watching a local process on a workstation
11:27	TimMc	Yeah, it's an odd little niche.
11:27	bbloom	TimMc: nah, it's pretty common
11:27	bbloom	TimMc: you need a heartbeat
11:28	brianwong	first thing you should do is find out if your workstation's service manager can start/restart it
11:28	TimMc	I have upstart, so that's a start.
11:28	bbloom	i know a few folks who run 10+ cron jobs a day on their machines & they get a status email from them. basically you add 1 extra cron job that runs after all the other ones and sends you a little text email with the output & any errors or anything
11:29	bbloom	log & grep & sendmail get the job done pretty easily
11:29	TimMc	:-)
11:39	clgv	TimMc: fail2ban watches logs and usually bans ip addresses on certain ports. it can send mails as well. there is a good chance to get it configured to only send you a mail
11:41	kasterma	Does anyone know how to get multiple incanted plots into one window? I am running an algorithm trying to keep an eye on multiple properties and the different windows are rather cumbersome.
11:41	kasterma	s/incanted/incanter/
11:54	technomancy	no, I like incanted
11:54	technomancy	incanter is for incanting plots
11:54	technomancy	when you incant them, they get incanted... makes sense to me =)
11:56	kasterma	mine must have become too incanted
11:59	clgv	kasterma: do not use `show` if you do not like the windows. instead embedded the plots in a your jframe where you want to have them ;)
12:00	kasterma	clgv: i.e. no way to avoid thinking of JFreeChart to do this?
12:01	clgv	kasterma: jfreechart is only responsible for the chart. incanter puts them in the jframe when you call show
12:02	kasterma	clgv: thx, I think that points me in the right direction to figure this out.
12:20	TimMc	bbloom: I like that approach, with cron.
12:25	pbostrom	xeqi: ping
12:47	jasonbray	Is there a specific version of JFreeChart I should use with Incanter? Getting a 'No matching method found' for draw in ChartFrame when saving pdfs.
12:53	clintnewsom	Does anyone out there know how to join a persistent vector in clojurescript?
12:55	dnolen	clintnewsom: what do you mean join?
12:56	clintnewsom	sorry, i mean to join as a string
12:56	clintnewsom	i.e. (clojure.string/join ", " [1 2 3])
12:58	dnolen	clintnewsom: you need to (:require [clojure.string :as string]) in your namespace delcaration and (string/join "," [1 2 3]) will work.
12:59	clintnewsom	thank you!
13:05	brianwong	hey clintnewsom!
13:05	brianwong	im learning clojure as well
13:05	clintnewsom	brianwong: awesome!
13:05	brianwong	happy to know that you are hacking away
13:06	clgv	jasonbray: it installs the version it needs
13:07	clgv	jasonbray: so if you did not specify a different (newer) version manually it should work. otherwise there is a bug
13:09	clintnewsom	brianwong: :-) good to see you here! you need to lead the cljoure revolution at nypl!
13:10	brianwong	im afraid I do not have the clout. I can at least use it for my projects.
13:12	clgv	nyp?
13:12	brianwong	we both work for the new york public library
13:12	clgv	ah ok^^
13:14	clintnewsom	brianwong: btw, I can't make it, but the Clojure meet up tonight looks pretty good
13:14	brianwong	it wasnt on my radar. Unfortunately, I cant make it either. Thanks for the heads up though.
13:20	gtrak	are folks planning on hanging around wednesday afternoon at clojure/west?
13:21	jeremyheiler	gtrak, yeah, i'll be around. my flight out of there is thursday.
13:26	augustl	how do I see the full stacktrace in lein repl, instead of just the message?
13:26	gtrak	*e
13:27	augustl	what's a good way to print the whole thing?
13:27	gtrak	.printStackTrace is the java way, clojure's got a package somewhere
13:27	gtrak	http://clojuredocs.org/clojure_core/clojure.stacktrace/print-stack-trace
13:28	augustl	nice, thanks
13:29	jeremyheiler	(pst) also works
13:30	jeremyheiler	That is, clojure.repl/pst
13:30	gtrak	ah
13:35	callenbot	having a grand time with korma lately.
13:36	callenbot	not sure how I'll feel when a more complicated query comes up though.
13:47	callenbot	dsantiago: how did you do the caching in stencil? LRU?
14:07	dsantiago	callenbot: The cache is pluggable.
14:08	dsantiago	https://github.com/davidsantiago/stencil#manual-cache-management
14:09	ChongLi	is there anything wrong with going ahead and extending the type of javascript objects for protocols like ILookup
14:09	ChongLi	?
14:10	ChongLi	makes it a lot cleaner to use them instead of aget all over the place
14:10	callenbot	dsantiago: but how does it work? :(
14:11	amalloy	ChongLi: that's a feature that's so obvious i'm pretty sure they thought of including it in cljs itself, but didn't include it; i bet there was a reason
14:12	callenbot	dsantiago: I'm considering giving Clabango a bionic upgrade.
14:12	ChongLi	amalloy: that's why I asked
14:12	amalloy	perhaps it's because you can't lookup anything but strings?
14:12	callenbot	dsantiago: stencil won the clojure template benchmark thing I did btw.
14:13	ChongLi	hmmm
14:13	ChongLi	so it's really a broken implementation of the protocol then
14:14	ChongLi	domina does this
14:14	ChongLi	https://github.com/levand/domina#event-objects
14:17	muhoo	i'm trying to access the raw body using this http://groups.google.com/group/compojure/browse_thread/thread/455e667c26913bd , but i can't find this request function anywhere. bare use, so i have NFI where it came from. also can't seem to find this duck-streams namespace, and there's no 'compojure namespace either.
14:17	technomancy	https://github.com/technomancy/leiningen/wiki/Faster <- tips for getting Leiningen to start faster; comments welcome
14:18	technomancy	or ... it's a wiki, I guess, so you can edit it yourself. whatever
14:18	muhoo	(request :body) <-- would be great, if only i could find that function.
14:19	technomancy	muhoo: duck-streams is from old monolithic clojure-contrib
14:19	weavejester	muhoo: What do you mean by request function? I can't seem to access the thread you're linking to.
14:19	muhoo	is that where request comes from?
14:19	weavejester	muhoo: The request is passed into the handler function as an argument.
14:19	weavejester	muhoo: e.g. (defn handler [request] ...)
14:20	xsyn	I'm very new to Clojure, and I was wondering if there was a way to go into a block, what for each function to return and only once it's returned go to the next function
14:20	muhoo	not if i'm um using the "/:id/food" destructuring, it appears
14:20	xsyn	make something procedural out of a functioal language
14:20	xsyn	ala https://gist.github.com/xsyn/4998355
14:20	weavejester	muhoo: Check out: https://github.com/weavejester/compojure/wiki/Destructuring-Syntax
14:21	weavejester	muhoo: If you have a route like "/:id/food"
14:21	technomancy	xsyn: that's how clojure works by default, though if you need multiple calls to become one expression you can use `do`
14:21	weavejester	muhoo: Then you can do something like (GET "/:id/food" [id :as {body :body}] …)
14:22	xsyn	technomancy: so I should remove the do in my example?
14:22	dnolen_	Added a bunch of ideas for GSoC 2013 projects, http://dev.clojure.org/display/community/Project+Ideas some them are doozies
14:23	ChongLi	dnolen_: wow you're going to mentor all of these?
14:23	technomancy	xsyn: the do doesn't make sense since its first form is a map. that map will never get returned.
14:24	dnolen_	ChongLi: no way, they are just ideas
14:24	ChongLi	ah ok haha
14:24	xsyn	nod
14:24	ChongLi	I see Ambrose has some stuff in there
14:24	technomancy	xsyn: each request can only have one response
14:26	muhoo	weavejester: http://groups.google.com/group/compojure/browse_thread/thread/455e667c26913bd0
14:26	xsyn	technomancy: cool, I think I was trying to be lazy and cheat that. So I should just set up a setup a couple of routes.
14:26	muhoo	weavejester: yep, (GET "/:id/food" [id :as {body :body}] ...)
14:26	weavejester	muhoo: Oh wow, that's old.
14:26	muhoo	looks like the winner, thanks!
14:27	weavejester	muhoo: I think that example is back from version 0.1.0. It might predate Ring.
14:28	ChongLi	is clooj meant to sound like kludge?
14:40	dnolen_	ChongLi: heh yes it is
14:45	ChongLi	hmmm, adding piggieback keeps breaking my project due to its use of an older gclosure library
14:48	pbostrom	ChongLi: I ran into that as well
14:50	pbostrom	ChongLi: are you using cljsbuild? I noticed that cljsbuild picks up the old Closure library because of the piggieback dependency, I don't understand why though, it seems like cljsbuild should maintain it's own Closure dep
14:51	ChongLi	yeah, cljsbuild
14:54	cfleming	Hi everyone
14:54	ChongLi	hey there
14:54	cfleming	I'm having a problem with AOT compilation
14:55	joegallo	do tell
14:56	cfleming	I'm working with a Java framework - when I try to AOT compile a file containing something like (def myvar (SomeClass/staticMethod x y z)) the compiler will attempt to evaluate the LHS during compilation
14:57	cfleming	I had expected that it would generate code with a static initialiser and call the code at class initialisation time
14:58	cfleming	i.e. like Object myvar = SomeClass.staticMethod(x, y, z) would in Java
14:58	joegallo	what is the evidence that you're using to determine that the latter behavior is what is happening? i'm not sure, but i think you've made a leap there.
14:58	joegallo	that is, I do A, I get B stacktrace, I've decided that C is why.
14:58	joegallo	You've told us A and C.
14:58	cfleming	I get an NPE during compilation, and the stack trace shows the compiler trying to execute the function
14:58	hiredman	cfleming: top level forms are executred when code is loaded
14:59	hiredman	cfleming: code is loaded when code is compiled
14:59	meegofl	Hi
15:00	meegofl	Small Q regarding maps and lists
15:00	cfleming	hiredman: is there a way to get the effect I want, i.e. to AOT compile something but defer the execution to when the NS is require'd?
15:00	meegofl	how can i create a map from 2 lists such as (key1 key2 key3) (val1 val2 val3)?
15:00	hiredman	cfleming: that are lots of ways
15:01	gfredericks	meegofl: zipmap
15:01	hiredman	for example how do you normally defer execution of until you want it?
15:01	cfleming	I could use a function, but in this case the static method is expensive
15:02	meegofl	gfredericks: Thanks
15:02	hiredman	so what do you normally do when a function call is expensive?
15:02	cfleming	I guess I could memoize it or something, but that seems like a fairly complex solution to a simple problem
15:02	meegofl	is there a way to do the same when first list items are not marked with ':'?
15:03	technomancy	cfleming: why do you say memoization is complex?
15:04	cfleming	technomancy: I guess I'm thinking of the implementation rather than the use of it
15:04	cfleming	This is something that's fairly simple to achieve in Java, I just wanted to check I wasn't missing something obvious
15:05	cfleming	In this case the code is called a lot of times, and for performance reasons just initialising a constant would be better
15:06	technomancy	Java's model is different because it doesn't have the compiler at runtime, so it's forced to introduce an otherwise-unnecessary distinction.
15:07	cfleming	Why do you say it's unnecessary?
15:07	warz	im trying to learn good formatting practices. is there any way to make the following middleware function, for ring, more concise or clean? https://gist.github.com/ryancole/4999031
15:07	cfleming	In this case it's pretty much exactly what I want.
15:08	warz	all it does is lookup a record in a database, using clutch, and add it to the ring request map
15:08	technomancy	cfleming: yes, your case is relatively uncommon, and it's easy to introduce delays either by a function or via `delay`. having a single execution environment that supports compilation as well as runtime is simpler.
15:08	technomancy	and more powerful
15:08	technomancy	it just seems awkward because it's unfamiliar
15:09	technomancy	cfleming: instead of introducing an entire new mode of operation just to support delaying something to runtime, you can use existing mechanisms for delays. fewer moving parts, etc
15:11	cfleming	But if I use delay, I'm still going to get the same problem with AOT compilation, right?
15:11	ChongLi	no
15:11	cfleming	i.e. it will be evaluated during compilation
15:11	technomancy	depends on when you force the delay. it's up to you.
15:11	ChongLi	delay delays evaluation
15:11	cfleming	Ah, I see - I have to deref it
15:11	ChongLi	that's the entire reason it exists :)
15:12	ChongLi	you have to force it
15:12	cfleming	Thanks.
15:12	ChongLi	you could also just wrap it in a function of no arguments
15:12	ChongLi	and then call taht
15:12	cfleming	The perils of having to integrate with Java frameworks
15:12	ChongLi	clojure has a lot of nice features for integrating with java frameworks
15:12	ChongLi	just takes some getting used to
15:13	cfleming	Yeah, but it has some awkward corners sometimes
15:13	cfleming	Another question - is it possible to get reflection warnings without actually fully compiling?
15:14	cfleming	In this case I'm only really trying to AOT compile to check that I've caught all the reflection warnings.
15:14	ChongLi	you mean with warn-on-reflection ?
15:14	cfleming	If I could do that then I can do without AOT for the majority of what I need to do.
15:15	cfleming	Right. Ideally I could do a lein check-reflection-warnings that would give me the warnings without having to compile everything.
15:15	ChongLi	put (set! warn-on-reflection true) at the top of a source file
15:15	hiredman	cfleming: have you seen `lein check` ?
15:16	ChongLi	cfleming: if you work in a repl you can just set that at the start of your session
15:16	ChongLi	and then as you work you'll get the warnings
15:16	ChongLi	http://clojuredocs.org/clojure_core/clojure.core/warn-on-reflection
15:16	cfleming	hiredman: I haven't, what does that do?
15:17	hiredman	read the docs for it
15:17	cfleming	ChongLi: I can't do that since this code is loaded inside the framework
15:17	hiredman	huh
15:17	hiredman	no docs
15:17	hiredman	technomancy: what gives?
15:18	cfleming	I can't find anything on it
15:18	hiredman	well just try it
15:18	cfleming	Unfortunately I'm not using leiningen yet for this project
15:19	ChongLi	ahhh
15:19	hiredman	well, that is your mistake right there
15:19	ChongLi	my hair is on fire!
15:19	technomancy	hiredman: dunno; I didn't write that one
15:19	technomancy	It does say "Check syntax and warn on reflection." at least though
15:19	cfleming	unfortunately it's not a trivial project to convert (intellj plugin)
15:19	ravster	hello all
15:19	technomancy	oh dear
15:20	hiredman	technomancy: it doesn't show up in lein's help
15:20	cfleming	Interesting, that does sound like exactly what I want.
15:20	hiredman	technomancy: hah, nm wrong version of lein of course
15:20	technomancy	aha
15:23	cfleming	technomancy: btw, the wget command in the lein 2 upgrade page needs a --no-check-certificate
15:23	technomancy	cfleming: erhm... that's really not a good idea to recommend by default
15:24	cfleming	Unfortunately the github cert isn't trusted
15:24	technomancy	you should probably fix your CAs
15:25	cfleming	Thanks, I'll look into that
15:25	Frozenlo`	,(= 0.0 0)

15:26	Frozenlock	The more you know...

15:26	pjstadig	Frozenlock: given what you know...be careful when dealing with JDBC
15:27	hyPiRion	,(== 0 0.0M) ; worth a shot, but digdec is mean

15:27	hyPiRion	generally use (< (abs (- a b)) epsilon) for floating point

15:29	TimMc	Math/abs, I guess
15:30	brehaut	is anyone else getting "Exception in thread "main" clojure.lang.LispReader$ReaderException: java.lang.RuntimeException: No reader function for tag ordered/map" when running lein kibit ?
15:31	Frozenlock	,(= 4/2 2)

15:33	clojurebot	true
15:33	hyPiRion	woop
15:33	hyPiRion	Now, that's dangerous to do in general.
15:34	Frozenlock	Eh, after #=, I feel like nothing's dangerous :P
15:35	rcg	is there something like junitreport for clojure tests?
15:35	rcg	i want to have some nice summary of unit test results
15:36	rcg	for now i run the stuff simply via leiningen
15:36	rcg	however, having a better overview would be nice
15:40	Frozenlock	I'm lost on this one... any idea what might be causing this? java.lang.NullPointerException: Numbers.java:3755 clojure.lang.Numbers.gt
15:49	stuartsierra	Frozenlock: Somewhere your code is comparing a nil to a number with >
15:49	Frozenlock	nvm, I was passing a `nil' when I was sure it was only numbers.
16:05	rhin0x	hi
16:05	rhin0x	I started toying with clojure 1.4 and have a question
16:06	xeqi	pbostrom: pong
16:07	rhin0x	why does '(map-indexed print "abcd")' give me '(0 a1 bnil 2 cnil 3 dnil nil)'
16:07	rhin0x	to be more specific
16:07	rhin0x	the nil are in strange places when I look at it
16:07	jeremyheiler	rhin0x, print returns nil
16:08	rhin0x	shouldn't this be like this '(0 anil 1 b nil 2 cnil 3 dnil)'
16:08	rhin0x	I know
16:08	rhin0x	houldn't be there a nill after every pair
16:08	rhin0x	?
16:09	TimMc	rhin0x: The printing of the output is being mixed with your explicit print commands.
16:09	jeremyheiler	The nils are being printed concurrently with the output.
16:09	TimMc	&(doall (map-indexed print "abcd"))
16:09	lazybot	⇒ 0 a1 b2 c3 d(nil nil nil nil)
16:10	rhin0x	ok, now it makes more sense :)
16:10	TimMc	Concurrency + lazy side-effects.
16:10	yedi	can we take a second to point and laugh and feel superior: http://discursive.com/2013/02/19/rails-you-have-turned-into-java-congratulations/
16:11	yedi	i know doing so is beneath some of you, but it'll make you feel good!
16:12	rhin0x	thank you very much
16:12	yedi	seriously though, i liked this quote: "Frameworks that Eat Frameworks don’t like it when you Customize the Frameworks they Eat"
16:17	ldh	just reading that myself
16:28	ravster	I'm trying to use wrap-basic-auth, but the following line inside a cond is blowing up with a "Can't cast to clojure.lang.IPersistentMap" error --------------------> ((:headers req) "authorization") (wrap-basic-authentication (partial create-session! handler) user/login)
16:29	ravster	I don't think its the wrap-basic-auth call, since the following works just fine -----> (def login (wrap-basic-authentication login-handler user/login))
16:30	xeqi	what is req?
16:30	ravster	oh, gah. just got it. I made the create-session! partial expect a full request, and wrap-ba is giving it only a usermap.
16:33	ravster	nvm. create-session! doesn't get called at all
16:34	ravster	xeqi: https://www.refheap.com/paste/11560 <----- is the req
16:34	pbostrom	xeqi: you were asking me what I was using clojail for; I put together a shareable web-based repl: http://cwo.io/
16:37	xeqi	pbostrom: neat. and that would be really annoying
16:39	pbostrom	xeqi: I'm working on integrating with paste sites like gist and refheap, and I started to notice that if I pulled in a paste with any defs it would blow up in different ways, luckily I was able to fix it with help from Raynes
16:45	olenhad	Hey guys, whats the current status of source maps for cljs?
16:46	ravster	fixed create-session! but it still doesn't get called. And the authentication function user/login doesn't get called either.
16:49	ToBeReplaced	dnolen_: Is there a way to have create an n-dimensional domain in core.logic.fd ... wondering how to represent cartesian coordinates
16:52	dnolen_	ToBeReplaced: no way to do that which is built in.
16:52	olenhad	Or rather,has any existing project started on multilevel source maps for cljs?
16:53	dnolen_	ToBeReplaced: tho the idea is that you could do that w/o much hassle yourself. I need to iron out the constraint protocols a bit more before it can be done reliably
16:53	dnolen_	olenhad: source map merging is already in a branch in ClojureScript
16:53	dnolen_	source-map is the branch
17:01	ToBeReplaced	dnolen_: okay thanks
17:02	ravster	https://www.refheap.com/paste/11563 <-- is there something wrong with my wrap-basic-authentication call? I'm unable to get anything printed from the user/login function.
17:05	harob	Hi all, I have a performance question: I would have thought that it is better to declare a regex outside of a frequently called function rather than inside it, to avoid having the regex be re-generated each call. But when I test in the REPL, `(time (dotimes [i 10000000] (re-find #"[1-9]ab(c\|d)" (str i "abdblabla"))))` is just as fast as `(time (dotimes [i 10000000] (re-find r (str i "abdblabla"))))`. How is this possible? Is the Clojure compiler doing somethin
17:05	harob	similar to string interning, to effectively only create the regex once?
17:07	dnolen_	harob: well it's a literal constant and Clojure optimizes those
17:07	TimMc	I believe regex literals (#"...") are compiled and stored as static fields.
17:07	TimMc	In any case, yes, the reader compiles them in advance.
17:08	harob	Ok, that makes sense, thanks.
17:09	harob	Do you know if the same applies to inner functions bound with letfn within frequently called functions? I get similar benchmarking results, but I don't have a good mental model for how Clojure is handling those.
17:10	AtKaaZ	can the currently defined namespace be aliased like with :as when :require happens in a different namespace?
17:11	AtKaaZ	aliased within itself I mean
17:11	TimMc	I doubt it, but give it a try.
17:12	AtKaaZ	it doesn't work like (ns a :as b)
17:12	AtKaaZ	I find myself copy pasting code which is fully qualified to the alias, then i've to search/replace
17:12	TimMc	Well, de-aliasing is easy enough.
17:13	AtKaaZ	well this seems to work (ns runtime.q (:require [runtime.q :as b]))
17:13	TimMc	s\|\balias/\|\|
17:13	TimMc	I'm surprised it works.
17:13	TimMc	It's pretty confusing, though.
17:14	AtKaaZ	i like it :)
17:14	AtKaaZ	i can't believe i didn't try it before asking, what was I thinking?!
17:15	sritchie	do you guys have advice for toggling development mode vs production mode in a compojure app?
17:15	harob	When I benchmark, `(time (dotimes [i 100000000] (letfn [(g [x] (inc x))] (g i))))` is as fast as `(letfn [(g [x] (inc x))] (time (dotimes [i 100000000] (g i))))` ; does this mean that Clojure is not regenerating the function each time in the first case? I have trouble seeing how it could handle things like closed-over variables in that case.
17:15	sritchie	I'm looking for dev mode to fire up a clojurescript repl, production mode to skip it
17:15	harob	sritchie: We use the RING_ENV environment variable, which I think is a common idiom."
17:16	hyPiRion	harob: `time` is generally a bad way to benchmark
17:16	hyPiRion	use criterium instead
17:16	hyPiRion	(At least that's a bit better, though not perfect)
17:17	harob	hyPiRion: Do you mean because of the warm-up iterations of the hotspot compiler? Or for another reason?
17:18	hyPiRion	well
17:19	hyPiRion	,(time (reduce + (range 1000000)))
17:19	clojurebot	"Elapsed time: 1417.94432 msecs"\n499999500000
17:19	hyPiRion	,(time (reduce + (range 1000000)))
17:19	clojurebot	"Elapsed time: 1323.675351 msecs"\n499999500000
17:20	TimMc	harob: GC, hotspot, caches, statistical analysis...
17:20	hyPiRion	It's hard to say anything when you got variation
17:20	sritchie	harob: gotcha
17:21	harob	Fair enough, point well taken, although in this case I was trying to check if two operations were the same order of magnitude speed.
17:21	sritchie	(defn dev-mode? [] ( = "dev" (System/GetEnv "RING_ENV")))
17:21	technomancy	sritchie: you can put a config file in dev-resources which tells it to launch the repl; that will only be visible via resources from lein if you're not in production
17:22	Frozenlock	Is there a map that will keep the order by which its elements were added?
17:22	technomancy	sritchie: I recommend not managing that kind of config by hand; either use environ or carica
17:22	sritchie	cool, hadn't seen carica
17:22	ravster	anyone here with experience in using remvee's basic-auth library for ring? I'm figure out what I'm doing wrong. https://www.refheap.com/paste/11563
17:23	technomancy	ravster: you need to pass req to the handler you get from wrap-basic-auth
17:23	holo	hi
17:24	technomancy	ravster: or better yet just use wrap-basic-auth as a real middleware
17:24	holo	is anyone being able to use google openid login url successfully in clojuredocs.org? I'm using https://www.google.com/accounts/o8/id but it doesn't work
17:25	ravster	real middleware?
17:25	ravster	I'm trying to get both basic- and cookie-auth working, and basic-auth wouldn't play with that.
17:26	ravster	so I'm trying to call it only when there isn't a user in :session.
17:26	ravster	how do I pass the req? I've tried (partial create-session! handler req)
17:27	sritchie	technomancy: feeling slow --
17:27	ravster	still getting -----------> java.lang.ClassCastException: api.utils.basic_authentication$wrap_basic_authentication$fn__115 cannot be cast to clojure.lang.IPersistentMap
17:27	sritchie	technomancy: how can I actually switch based on the value in ring_env? I can do it manually, but you're recommending against this
17:27	sritchie	manually meaning, System/getEnv
17:28	technomancy	sritchie: I just mean I don't recommend setting RING_ENV by hand on each dev box you work on; using environ is fine
17:28	technomancy	check (:ring-env env) or whatever
17:28	technomancy	actually no, that's silly
17:28	technomancy	pick a better name
17:29	sritchie	oh, I see, the "environ" library
17:29	sritchie	thought you meant the java env
17:29	technomancy	oh right
17:30	sritchie	nice! okay, great, environ looks like the way to go.
17:31	sritchie	and pick something other than RING_ENV because ring's using it? seems like it might be good, since ring uses the same switch, right?
17:31	technomancy	oh, does ring actually use that? if so that's fine.
17:31	technomancy	otherwise choose a name that actually reflects what you want to use it for
17:32	callenbot	sritchie: http://www.luminusweb.net/
17:32	callenbot	sritchie: best practices for this can be found in Luminus
17:32	callenbot	sritchie: you should try using it
17:33	callenbot	sritchie: we use lein ring and all that fun stuff.
17:33	sritchie	interesting, cool
17:33	sritchie	does luminus pick up where noir left off?
17:33	callenbot	sritchie: no, it's more "close to the source"
17:33	callenbot	sritchie: it uses lib-noir but it is largely vanilla Ring.
17:33	brehaut	yogthos: you are required in the lobby
17:33	callenbot	sritchie: I've got a fairly involved Luminus-derived vanilla Ring app that you could learn from.
17:34	sritchie	callenbot: I'd love to take a look
17:34	sritchie	I've just started working more on paddleguru.com
17:34	sritchie	which ran on noir
17:34	sritchie	(needs a designer :)
17:34	technomancy	environ is pretty straightforward to figure out on its own though
17:34	sritchie	technomancy: yup, environis a great tip
17:34	callenbot	sritchie: what's the database?
17:34	sritchie	couchdb
17:35	callenbot	:
17:35	sritchie	it's been really good, really hoping that cemerick keeps devving on the plugin
17:36	callenbot	I'm not allowed to say anything, I promised Raynes I'd be nice.
17:36	callenbot	sritchie: I used to work with one of the largest Couch clusters that existed at the time. I've not worked with it since. Draw thine own conclusions.
17:36	cemerick	sritchie: I'm saved by the couch api not moving much ;-P
17:36	sritchie	callenbot: where did you go from couch?
17:37	callenbot	sritchie: mixture of PostgreSQL, MongoDB, and Redis depending on the problem being solved.
17:37	callenbot	sritchie: for the analytics stuff I used to use couch for, I use PostgreSQL or Hadoop.
17:38	callenbot	sritchie: but I used Couch for what was literally its prime use-case and it was still fairly awful.
17:38	harob	Alright, so I benched with criterium and got the same results: `(letfn [(g [x] (inc x))] (criterium.core/bench (g 200)))` is the same speed as `(criterium.core/beanch (letfn [(g [x] (inc x))] (g 200)))` . I'm deducing that this means that there is no perf overhead to having a letfn function declaration within a frequently called outer function. Does anyone have any intuition of how Clojure can do this (i.e. not regenerate the function each time)? And does that
17:38	harob	only apply if the inner function does not close over any variables?
17:39	callenbot	sritchie: this is vanilla Couch I speak of, I haven't tried CouchBase 1.x or 2.0
17:39	callenbot	mostly due to emotional scarring
17:39	cemerick	bbloom: FYI: (template (foo ())) => (foo nil)
17:40	sritchie	callenbot: man, I'm curious about what the pain was
17:40	sritchie	callenbot: building views with mapreduce has been working really well
17:40	bbloom	,`()
17:40	clojurebot	()
17:40	callenbot	sritchie: you're working on a side project
17:40	bbloom	cemerick: ok, i'll fix it :-)
17:40	cemerick	callenbot: couchbase != couchdb
17:40	callenbot	cemerick: I KNOW THAT
17:40	callenbot	cemerick: I was clarifying that I was speaking only about CouchDB
17:40	cemerick	OKAY
17:40	callenbot	sritchie: you could make-do with flat files on a side project.
17:41	callenbot	cemerick: I wouldn't have made the distinction otherwise.
17:41	sritchie	haha, fair enough. you're saying if I tried to use this at twitter I'd be a bit fucked.
17:41	callenbot	sritchie: that's not really the point
17:41	callenbot	sritchie: it sucks for small stuff too.
17:41	callenbot	sritchie: I asked you what database you were using because one of the pages felt slow.
17:41	sritchie	ah
17:41	sritchie	gotcha
17:42	cemerick	callenbot: The preponderance of large couch deployments (and very, very large bigcouch deployments) doesn't back that up.
17:42	sritchie	cemerick, what say you?
17:42	callenbot	cemerick: lots of people use MySQL too
17:42	callenbot	cemerick: doesn't mean it doesn't suck.
17:42	sritchie	callenbot: what specific problem did you find?
17:42	callenbot	religion, databases, etc. Number of deployments don't mean much.
17:42	sritchie	speed?
17:42	sritchie
17:42	clojurebot	speed is dangerous
17:42	cemerick	bbloom: I could put a patch together if you care to wait, but I figure it's a quickie.
17:43	sritchie	if it sucks, I want to know, I just haven't hit too much pain yet
17:43	bbloom	cemerick: annoyingly, i can't see a way to do it without special casing it
17:43	cemerick	"sucked for me" isn't much of an argument
17:43	ravster	technomancy: how would I pass the request object to the handler function from wrap-basic-authentication?
17:43	cemerick	bbloom: I thought it was special-cased in LispReader? ;-P
17:43	callenbot	sritchie: http://blog.woobling.org/2009/05/why-i-dont-use-couchdb.html I don't need to repeat what others have covered.
17:43	callenbot	cemerick: ^^
17:44	cemerick	I don't have a dog in this fight, particularly. But, saying "couch sucks" is silly.
17:45	callenbot	sritchie: I've also found that if you need to query "documents", Lucene is an order of magnitude faster
17:45	sritchie	callenbot: yeah, I'm not a huge evangelist, just looking for what to watch out for as we move forward
17:47	callenbot	sritchie: I'd avoid using unusual abandoned document stores for anything important unless you really know what you're doing.
17:47	technomancy	someone's database choices are like their ex-girlfriends; you don't know all the details, and you probably don't want to.
17:47	brehaut	technomancy: haha
17:47	brehaut	and wise
17:47	callenbot	technomancy: it's something I have experience with and I don't want some poor schmuck contractor to have to clean it up.
17:47	callenbot	technomancy: I don't pipe up unless I know
17:48	callenbot	most of my career has been cleaning up fuck-ups and careless decisions like that.
17:48	callenbot	I'd rather less of it be so.
17:48	callenbot	engineers should know better.
17:48	technomancy	brehaut: I can't remember who said that, or I'd attempt proper attribution
17:48	technomancy	callenbot: for paddleguru.com? really?
17:48	callenbot	technomancy: I said it was whatever for a side project.
17:48	bbloom	cemerick_away: heh check this out:
17:49	bbloom	,[(list*) (apply list nil)]
17:49	clojurebot	#<ArityException clojure.lang.ArityException: Wrong number of args (0) passed to: core$list-STAR->
17:49	bbloom	,[(list* nil) (apply list nil)]
17:49	clojurebot	[nil ()]
17:49	technomancy	callenbot: ok, fair enough
17:50	bbloom	cemerick_away: pushed 33c5b5a & deploying it now
17:50	sritchie	callenbot: yeah, I don't anticipate hundreds of thousands of users, unfortunately
17:51	callenbot	technomancy: but if you're being paid to build something, you shouldn't subject your client to absurd and not-thought-out technology decisions. I use my side projects to test new things, personally.
17:51	sritchie	yeah, this is something I started, then handed off to a buddy --
17:51	technomancy	sure
17:51	sritchie	he's been using couch for a while, now I'm coming back into clojure from some time in scala-land
17:51	callenbot	sritchie: pro-tip: don't bother trying to make views faster. Just cache.
18:05	edoloughlin	I'm returning to a dormant project and migrating it to 1.4. I've discovered that in the CCW repl I can no longer redefine functions. The (defn) or (defn-) evaluates and returns ok but the functions are not changed - whatever was loaded when the repl started is still executed. Any ideas?
18:06	Raynes	Has refheap been working well today?
18:07	callenbot	Raynes: works here boss.
18:07	Raynes	Good news.
18:07	Raynes	I kinda pushed a total rewrite of the views and then just bugged off and went to bed last night.
18:07	Raynes	:p
18:07	Raynes	Didn't do much QA.
18:09	callenbot	Raynes: it's a free service. shrug
18:09	Raynes	I still kind of care about it though
18:09	Raynes	Especially since it is now a live example of laser.
18:09	callenbot	Sure.
18:09	ravster	okay, so (do(let [foo (wrap-basic-authentication (partial create-session! handler req) user/login)])) works and "lein test" returns 1 failure and 1 error. But if I have the wrap-basic-auth call all by itself, lein test gives 0 fails and 2 errors. What am I not understanding over here?
18:10	callenbot	Raynes: seems snappy/fast to me.
18:10	callenbot	Raynes: are you caching recent pastes?
18:10	Raynes	callenbot: No.
18:10	Raynes	Define 'caching'
18:11	Raynes	I never run pastes through pygments more than once. I store that in the db to speed thing sup.
18:11	Raynes	But no caching of anything besides that.
18:11	callenbot	Raynes: db caching
18:12	callenbot	so, no, I guess.
18:13	Raynes	It's probably faster because it isn't on heroku, callenbot.
18:13	callenbot	Raynes: where's the MongoDB instance?
18:13	Raynes	On the same server.
18:13	callenbot	Raynes: that'd be why.
18:13	callenbot	Raynes: fast VPS
18:15	brehaut	oh nice, jetty has aquired spdy support
18:15	brehaut	apparently a while ago too
18:15	callenbot	brehaut: GAE is Jetty
18:15	callenbot	brehaut: SPDY is Google
18:15	callenbot	brehaut: GAE is Google
18:16	technomancy	oh oh, I know this
18:16	technomancy	transitive property of "is"
18:19	hyPiRion	Well
18:20	hyPiRion	transitivity isn't enough here I think. Like mathematically.
18:20	augustl	converting from Ruby's bcrypt to the JBcrypt module is proving to be quite challenging..
18:20	TimMc	Needs to be symmetric as well, yeah?
18:20	callenbot	augustl: don't.
18:20	hyPiRion	TimMc: +1
18:20	callenbot	augustl: use lib-noir crypt.
18:21	hyPiRion	Though I'm usually thinking of isa-relation and uses-relations
18:21	callenbot	augustl: although that itself is [org.mindrot/jbcrypt "0.3m"]
18:23	augustl	ah, it was actually quite easy, I just had to figure out how sorcery (super magic authentication system for Rails) worked
18:23	augustl	it uses its own salt for some reason, that it appends to the password before authenticating against the bcrypt hash
18:23	callenbot	augustl: that is awful.
18:24	augustl	(org.mindrot.jbcrypt.BCrypt/checkpw (str password-from-user salt-from-sorcery) bcrypt-hash-from-sorcery)
18:24	augustl	callenbot: isn't the bcrypt hash both a hash and a salt?
18:24	technomancy	well... for a library named sorcery, you should expect it to do crazy magic behind your back
18:24	technomancy	(says a guy named technomancy)
18:24	augustl	indeed :) I'm glad I ported this system from Rails to Clojure
18:25	callenbot	augustl: I came to Clojure from Python
18:25	callenbot	augustl: although i used to do Ruby
18:25	augustl	not that Rails itself is bad, but this particular app is full of magic libraries like sorcery, that I have to reverse engineer to achieve portability ;)
18:26	brehaut	technomancy: magic like making maven reasonable?
18:26	brehaut	or some approximation of reasonable
18:27	callenbot	augustl: I prefer to work with things I mostly understand or better.
18:27	augustl	speaking of maven and magic :) I'm using ZeroMQ in this project, managing the JNI glue is quite painful. Ruby-gems will automatically compile their own native extensions on demand, seems I have to do it by hand for maven/leiningen.
18:27	technomancy	rubygems still needs dev headers, and recompiles them for every install, which is nuts
18:28	technomancy	augustl: you can do it automatically with lein, it's just the responsibility of the packager to compile it properly
18:28	technomancy	...and nobody who uses native deps has bothered to document it yet =\
18:29	amalloy	i wonder if anyone has an opinion on the nicer-looking way to implement a multi-arity function by reducing itself. given that the two-arity clause works, which is better for 3+ args? ([x y & more] (reduce f (list* x y more))), or ([x y & more] (reduce f x (cons y more)))?
18:30	Bronsa	(reduce f (f x y) more)?
18:30	hiredman	amalloy: x y & more is an error if you have a 2 arity
18:30	hiredman	& more matches 0 or more args
18:30	lazybot	java.lang.RuntimeException: Unable to resolve symbol: more in this context
18:30	amalloy	&((fn ([x y] y) ([x y & more] more)) 1 2 3)
18:30	lazybot	⇒ (3)
18:31	amalloy	i dunno if you still have lazybot on /ignore, but the result is (3)
18:31	hiredman	amalloy: sure, but it is a logical error
18:32	amalloy	i don't understand that claim
18:32	augustl	technomancy: ah, so it is possible to create jar files that compile the JNI stuff on install?
18:32	augustl	if so, got a link? :)
18:32	hiredman	,((fn ([y] y) ([x y & more] more)) 1 2 3)
18:32	clojurebot	(3)
18:32	hiredman	oh
18:32	technomancy	augustl: no, not on install. you compile them and put the artifacts in the jar and deploy that jar
18:32	technomancy	compiling on install is crazy
18:32	hiredman	,((fn ([y] y) ([x y & more] more)) 1 3)
18:32	clojurebot	nil
18:32	hiredman	,((fn ([x y] y) ([x y & more] more)) 1 3)
18:32	clojurebot	3
18:33	hiredman	,((fn ([x y & more] more)) 1 3)
18:33	clojurebot	nil
18:33	augustl	technomancy: isn't that problematic? Since the reason it should compile on install is that it needs to know about the stuff you already have on your system, in my case the install of zeromq itself
18:33	callenbot	amalloy: http://blog.darevay.com/2011/08/briefly-the-arity-reduce-pattern-in-clojure/ ?
18:33	technomancy	augustl: the jar should include zeromq
18:33	technomancy	static linking is the only way to do this that isn't crazy
18:34	technomancy	https://github.com/technomancy/leiningen/blob/master/leiningen-core/src/leiningen/core/classpath.clj#L42
18:34	augustl	but the compiled zeromq itself is architecture specific (32bit vs 64 bit)
18:34	technomancy	augustl: where "should" here is a Leiningen convention; maven itself has nothing at all for this unfortunately
18:34	technomancy	augustl: yep. put them both in the jar.
18:34	augustl	I see
18:35	hiredman	logically [x y & foo] is not a function that takes some number of arguments greater than 2, it is a function that takes 2 arguments or more
18:35	technomancy	the alternative is either 0) rubygems or 1) what you're currently suffering through.
18:35	augustl	so it would make sense to create a jar for jzmq that includes this and put it on clojars?
18:35	technomancy	augustl: I think someone's already done that
18:35	hiredman	so and (([x y] …) ([x y & more] …)) logically both overlap at arity 2
18:35	technomancy	also: 32-bit? seriously? =)
18:35	augustl	technomancy: I'll check that out, tnx
18:35	callenbot	who runs zeromq on a 32-bit server?
18:36	callenbot	jeez, let me whip out my 486DX web server
18:36	technomancy	augustl: worst case: you add an architecture-specific line to :dependencies
18:36	amalloy	i don't see your point, hiredman. as long as i'm aware, when writing my function, that the [x y] clause exists and (f 1 2) will be sent to it, then writing [x y & more] to expect 3+ args is fine. i'm aware that i don't need the two-arg case, if i wanted to implement that in my 2+ arity, but implementing 3+ in terms of 2+ is often clearer
18:36	amalloy	er, in terms of 2
18:37	augustl	callenbot: is zeromq specifically bad in 32 bit? Or are you talking about 32bit in genreal?
18:37	technomancy	augustl: we could use some help documenting this stuff if you're familiar with JNI
18:37	technomancy	most people won't touch it
18:38	augustl	beautiful.. https://www.refheap.com/paste/11569
18:38	augustl	technomancy: I would love to help out, I'm set on using zeromq and I've certainly felt the pain
18:38	amalloy	for example, the defintion of clojure.core/=
18:38	hiredman	amalloy: regardless of what the compiler allows, both arities in that case accept 2 args, which is ridiculous
18:39	augustl	technomancy: what wold you like documented specifically?
18:40	hyPiRion	hiredman: There are worse things
18:40	hyPiRion	like
18:40	hyPiRion	,(false? (Boolean. false))
18:40	clojurebot	false
18:40	TimMc	There are always worse things. :-)
18:40	technomancy	augustl: well... the process of packaging a jar that contains native components, I suppose
18:40	augustl	technomancy: I see
18:40	amalloy	hyPiRion: the discussion doesn't seem in need of a red herring at this time
18:41	augustl	technomancy: seems like it exists for zeromq yeah, https://clojars.org/brh/jzmq-native-deps for example
18:41	technomancy	augustl: I suppose some kind of integration with autotools might be necessary? that kind of stuff is over my head.
18:42	technomancy	at least we should document the structure of the jar that Leiningen looks for
18:42	augustl	me too, I don't really know what all this stuff actually is..
18:42	hyPiRion	amalloy: Ah, no intent to direct the talk away from the arity thing.
18:43	hyPiRion	Ping me when you need that red herring.
18:43	hiredman	amalloy: anyway, core does it that ways [x y] [x y & more] so it is unlikely to change suddenly
18:44	amalloy	indeed. i wasn't asking whether to use [x y] [x y & more] (i have no intention to do anything different), just seeing if anyone felt strongly about the body of my [x y & more] clause

18:50	clojurebot	#<ArithmeticException java.lang.ArithmeticException: integer overflow>
18:51	hiredman	bendlas: unchecked math only works on primitives
18:51	bendlas	this is a bug, right?
18:51	amalloy	,(unchecked-multiply (unchecked-int 0xcafebabe) (unchecked-int 0xcafebabe))
18:51	clojurebot	790811295510209796
18:51	bendlas	so unchecked multiply defaulting to checked multiply when faced with boxed values is a feature?
18:52	TimMc	That's surprising and unexpected behavior.
18:52	Frozenlock	Is there some css and compojure functions to pretty-print clojure code in a webpage? (with colors and all that sweet stuff)
18:53	hiredman	bendlas: I doubt anyone has bothered to care because most people who want one want the other
18:53	hiredman	the main argument for both unchecked math and primitives are speed
18:53	TimMc	I'm more concerned about the misleading error.
18:54	amalloy	TimMc: misleading?
18:54	TimMc	Well, more "baffling".
18:54	bendlas	it's unexpected, but at least it doesn't fail silently
18:54	TimMc	Not sure what's to be done about it, though.
18:55	bendlas	in this case it's unexpected, because unchecked- fns are supposed to fail silently
18:55	TimMc	bendlas: Only once you hit a large enough number.
18:57	TimMc	It would be much safer to fail on boxed inputs, always.
18:59	bendlas	TimMc: I'd say so too, edge cases still should have clean edges
19:14	sritchie	cemerick: do you have any good advice for a clojurescript repl in emacs?
19:14	Raynes	http://24.media.tumblr.com/tumblr_m4awrpjJjL1rvnefzo1_500.gif
19:16	callenbot	sritchie: if you discover such a thing, come back here and tell us about it.
19:16	sritchie	:)
19:16	callenbot	sritchie: https://github.com/dustingetz/cljs-bootstrap
19:17	bendlas	sritchie: not cemerick, but inferior-lisp in combination with lein cljsbuild browser-repl has served me well
19:17	sritchie	ah, yeah, that makes sense
19:17	sritchie	just have inferior-lisp run that command for cljs files
19:17	cemerick	sritchie: see piggieback
19:17	bendlas	I think there is even a tutorial for that on google
19:18	sritchie	cemerick: link?
19:18	sritchie	oh, was searching for piggyback
19:18	cemerick	sritchie: http://github.com/cemerick/piggieback
19:33	sritchie	anyone using shoreleave?
19:33	ohpauleez	yes
19:33	ohpauleez	:)
19:33	muhoo	heh
19:33	Raynes	I was about to say that I bet ohpauleez is using it.
19:33	Raynes	I wonder if anybody uses laser.
19:33	Raynes	Oh wait.
19:34	ohpauleez	sritchie: I know of a good few people that are using it in production
19:34	sritchie	looking at shoreleave-remote
19:34	ohpauleez	I have a few apps in production that are using various pieces
19:34	sritchie	vs fetch, for example
19:34	ohpauleez	sritchie: Most people just the the remote stuff and the pubsub stuff
19:34	sritchie	or some other similar thing I haven't heard of
19:34	sritchie	gotcha
19:35	ohpauleez	sritchie: remotes in shoreleave are CSRF-protected. Additionally the interfaces are extended to handled pooled XHR, one-off XHR, JSONP
19:36	ohpauleez	the whole suite of shoreleave is basically protocols extended to JS internals, so you can use them with standard Clojure functions
19:37	muhoo	what about the read-eval thing?
19:37	ohpauleez	sritchie: updates forthcoming, but https://github.com/shoreleave/shoreleave-baseline
19:38	sritchie	hey, nice
19:38	sritchie	thanks
19:38	ohpauleez	muhoo: shoreleave server side uses safe-read (as does fetch). In the next release (once 1.5 final is out, that'll be replaced with read-edn
19:39	TimMc	Has Core not yet released an edn-reader contrib?
19:39	muhoo	ohpauleez: cool, thanks
19:39	ohpauleez	TimMc: I'm not sure if the reader contrib has cut the release yet. The code is there
19:40	tommo_	guys, how can i execute an expression x times?
19:41	gfredericks	dotimes
19:41	tommo_	<3
19:41	gfredericks	,(dotimes [n 3] (println n))
19:41	clojurebot	0\n1\n2\n
19:41	TimMc	Wow, clojurebot got an upgrade!
19:42	TimMc	The old version would have spammed 3 or 4 lines to the channel.
19:44	gfredericks	yeah he's been like that for a month or two I think
19:44	gfredericks	at least
19:44	gfredericks	,(println "0\\n1\\n2\\n")
19:44	clojurebot	0\n1\n2\n\n
19:53	Frozenlock	Raynes: after your picture, now it's the repository that's changing under me. -_-
19:53	Raynes	Frozenlock: Heh, which repository?
19:53	Frozenlock	clojail
19:53	Raynes	Oh, you were doing something with clojail?
19:54	Raynes	I have this feeling we might have talked about this already and I've forgotten, so sorry if so.
19:54	Frozenlock	I'm using it, not changing anything.
19:55	Frozenlock	Still, I'm curious if there's any important modificiations...
19:57	Raynes	Frozenlock: This last one is important if you're allowing def.
19:57	Raynes	Any update can be pretty important with clojail.
19:57	Raynes	There are holes that need fixed right now, as xeqi will testify since he found all of the damn things.
19:57	xeqi	amalloy found one of them
19:57	Raynes	amalloy doesn't count, he is a clojail dev.
19:58	amalloy	after all these reports, you're claiming xeqi isn't?
19:58	sritchie	ohpauleez: Exception: java.lang.NullPointerException: null
19:58	sritchie	StringReader.java:33 java.io.StringReader.<init>
19:58	sritchie	RT.java:1705 clojure.lang.RT.readString
19:58	sritchie	core.clj:3361 clojure.core/read-string
19:58	sritchie	whoops, sorry
19:58	Raynes	xeqi has never fixed any of them, amalloy.
19:58	sritchie	getting that in the remote example.
19:58	Raynes	And that's bad and he should feel bad.
19:58	amalloy	heathen
19:58	sritchie	ohpauleez: 0.2.2 is the current version?
19:58	sritchie	ohpauleez: this is with shoreleave-remote-ring
19:58	ohpauleez	I would use the snapshot, or baseline (which is 0.3 - to be released)
19:59	Raynes	yogthos: You're pretty hilarious.
20:00	yogthos	lol
20:00	yogthos	you saw that eh :P
20:00	Raynes	yogthos: You don't need to do a pull request FOR EVERYTHING
20:00	yogthos	haha did you see the break though :P
20:00	Raynes	Nope.
20:00	yogthos	so glad we got travis going
20:00	Raynes	Because I don't look at 90% of your pull requests.
20:00	Raynes	Because they're unnecessary. :P
20:00	sritchie	ohpauleez: 0.2.2-SNAPSHOT is more up to date than 0.2.2?
20:00	yogthos	I added get-in to session, but forgot we were using it from core :)
20:00	sritchie	I don't see a higher snapshot
20:00	yogthos	:)
20:00	Raynes	I trust you, you write good code, you don't break things (well, usually).
20:01	yogthos	usually :P
20:01	yogthos	and when I do, I fix it eventually :)
20:01	ohpauleez	sritchie: Oh weird, I thought there was a 0.2.3-shapshot
20:01	Raynes	Yes, yes you do.
20:01	yogthos	but helps me keep it clear too, I like the paper trail
20:01	ohpauleez	sritchie: https://clojars.org/shoreleave/versions/0.2.3-SNAPSHOT
20:01	Raynes	Well, you're free to keep doing it.
20:01	Raynes	It's just amusing to me.
20:01	sritchie	gotcha
20:02	sritchie	ohpauleez: but not for shoreleave-remote
20:02	yogthos	lol
20:02	ohpauleez	sritchie: 0.3 is just around the corner
20:02	sritchie	so to play with that for now,
20:02	sritchie	I should use baseline locally, sounds like?
20:03	ohpauleez	sritchie: Yeah, baseline is meant to be used like people use CS:One
20:03	ohpauleez	you clone it, and write your application
20:04	sritchie	I'm sad the modularity is gone
20:05	sritchie	the remote functionality would be great for very simple apps, for example
20:05	sritchie	I'm writing a tile server in clojure with a cljs front end --
20:05	sritchie	the remotes allow the cljs to call the server, which generates and caches tiles
20:06	sritchie	which would be great to break out
20:07	ohpauleez	sritchie: It'll be back
20:07	ohpauleez	once I push all the 0.3 releases of the modules
20:07	ohpauleez	if you want
20:08	ohpauleez	just go in src/shoreleave and rm the directories you don't want
20:08	Frozenlock	Raynes: This might be the desired behavior, but I just realized that clojail doesn't seem to use the example.policy file. Rather, the permissions are specified in the :context
20:08	Raynes	Frozenlock: The policy file is what you have to set globally so that once the JVM sandbox is activated, it doesn't affect your non-sandboxed code.
20:09	Frozenlock	Oh!
20:11	Frozenlock	That explains why I couldn't change my sandbox policy by changing the example.policy...
20:11	Raynes	Yep.
20:11	Raynes	And if your sandbox policy was the example policy you'd be allowing everything.
20:12	Raynes	Probably not what you want. ;)
20:12	Frozenlock	Actually in this case, that's exactly what I want :P
20:13	Frozenlock	So why a sandbox you might ask... I prefer having it ready, in case I want to change the policy.
20:14	callenbot	shoreleave is impressive but the cljs compilation errors were brutal.
20:14	ohpauleez	callenbot: all fixed on 0.3
20:14	callenbot	not specific to shoreleave, I mean.
20:15	callenbot	in general it was just really hard to tell why any particular bit of cljs was breaking.
20:15	callenbot	yogthos got bit by some of the same things I did.
20:15	ohpauleez	aahhh there were some warnings from old print stuff and local storage
20:15	callenbot	ohpauleez: I'll give it another whirl when 0.3 hits but cljs needs source maps in a BAD way.
20:15	ohpauleez	callenbot: But yes, debugging in CLJS is a challenge sometimes
20:15	callenbot	it is seriously the only reason most people I know don't use it.
20:15	Frozenlock	callenbot: nonsense! You just have to find your "k" property, undefined for the object "l".
20:16	callenbot	Frozenlock: that is far from representative of the errors I've encountered. I usually see worse.
20:16	Frozenlock	Worse than a munged name? Must be hell to debug :p
20:17	callenbot	Frozenlock: yes.
20:17	callenbot	I love cljs but the errors are a 100% blocking issue for me to use it in anything
20:18	callenbot	you need to have a PhD like the prismatic guys to work past that :)
20:19	ohpauleez	callenbot: I don't think it's that bad
20:19	callenbot	ohpauleez: is websockets or browserchannel in the cards for shoreleave?
20:19	ohpauleez	you do need JS knowledge to effectively use it
20:19	callenbot	ohpauleez: I have a decade of serious-face-not-jQuery JS experience.
20:19	Frozenlock	ohpauleez: that's quite a big deal.
20:20	ohpauleez	callenbot: People ask me about that a lot (websockets) - I've done it in one app without an issue.
20:20	ohpauleez	If someone submitted an issue (a patch even better) I would totally put it in
20:21	callenbot	ohpauleez: BrowserChannel might be better than ws.
20:21	callenbot	ohpauleez: http://closure-library.googlecode.com/svn-history/r144/docs/closure_goog_net_browserchannel.js.html it's already in Goog Closure.
20:21	ohpauleez	So, I already have the base of some stuff around the HTML5 messaging API (which I support in the pubsub)
20:22	ohpauleez	if I took on BC, I'd do a refactor across the modules to some protocol
20:22	ohpauleez	as it stands right now, I use remotes+JSONP for most things
20:22	callenbot	ohpauleez: https://github.com/ohpauleez/shoreleave/issues/7
20:23	callenbot	ohpauleez: fyi BrowserChannel works even on IE 5.5 :P
20:23	ohpauleez	callenbot: BC is technically in CLJS core
20:23	ohpauleez	it's used for Browser REPL
20:23	callenbot	ohpauleez: that's the point I was making.
20:23	callenbot	ohpauleez: that it's already supported to some degree
20:24	ohpauleez	ahh gotcha
20:24	callenbot	I just want shoreleave to offer it as an option ;)
20:24	ohpauleez	ahah
20:24	callenbot	ohpauleez: BECAUSE I NEED SPEEEEEEEEEEEEEEEEEEED
20:24	ohpauleez	I want that to. patches welcome
20:24	ohpauleez	:)
20:24	ohpauleez	remotes + JSONP + SPDY on JETTY has been acceptably fast for all my stuff
20:24	callenbot	ohpauleez: I need to fix clabango first.
20:25	ohpauleez	except one thing, where I needed ws
20:25	callenbot	ohpauleez: what'd you need ws for?
20:26	augustl	what's the easiest way to execute a .clj file in the context of a leiningen project? My use-case is a script that imports old data from a json file into the database.
20:27	ohpauleez	AV workbench, where I was streaming raw data packets to the client in a browser
20:27	ohpauleez	and the browser was building png objects
20:27	ohpauleez	and flipping the image themselves
20:27	callenbot	yogthos\|away: that pull request is the nicest I've been to anybody in months.
20:27	callenbot	augustl: lein run?
20:28	augustl	callenbot: that only supports one single main though, I might have a bunch of different tasks
20:28	callenbot	dafuq.
20:28	callenbot	augustl: https://github.com/technomancy/leiningen/blob/master/src/leiningen/run.clj
20:28	callenbot	augustl: false, sir.
20:28	augustl	and I already use :main to run my actual app
20:28	callenbot	augustl: read the code
20:28	callenbot	augustl: it does what you want.
20:29	callenbot	augustl: somehow you're even lazier than I am, bravo.
20:29	Frozenlock	,gentlemen
20:29	clojurebot	#<CompilerException java.lang.RuntimeException: Unable to resolve symbol: gentlemen in this context, compiling:(NO_SOURCE_PATH:0:0)>
20:29	Frozenlock	wrong command?
20:29	TimMc	~gentlemen
20:29	clojurebot	You can't fight in here. This is the war room.
20:35	technomancy	~botsnack
20:35	clojurebot	Thanks! Can I have chocolate next time
20:37	yedi	callenbot: this breaks clabango
20:37	yedi	var wizard_options = {buttons: {nextText: '<i class="icon-download"></i>'}}
20:38	yedi	i wonder if it also breaks djangos templating library too
20:42	brehaut	yedi: how is it used in the template?
20:42	brehaut	because i'd be surprised
20:42	brehaut	django.template.Template("{{ buttons }}").render(django.template.Context({"buttons": {"nextText": '<i class="icon-download"></i>'}})) #=> u'{'nextText': '<i class="icon-download"></i>'}'
20:43	yedi	brehaut: sorry it doesn't break clabango, but it breaks the javascript. the }} just is removed at the end
20:48	callenbot	yedi: patch it!
20:48	yedi	yea
20:49	yedi	it's a great opportunity for me to do some opensource hacking
20:49	abp`	Why don't you guys just use hiccup. :P
20:51	sritchie	ohpauleez: almost working w/ remotes :)
20:51	sritchie	Uncaught Error: goog.require could not find: shoreleave.remotes.http_rpc
20:51	sritchie	that just started appearing
20:51	yedi	hey brehaut: i just realized that was the django template fn (not clabango's) it also seems to be missing the }} at the end
20:52	ohpauleez	sritchie: That looks like the CLJS compiler is messing up the import statements
20:52	yedi	starting to look like it's that way by design possibly?
20:52	sritchie	ohpauleez: yup
20:52	sritchie	will retry in something clean
20:52	ohpauleez	cool, thanks
20:52	ohpauleez	keep me posted because I have deep knowledge in that part of the CLJS compiler
20:52	ohpauleez	sritchie: ^
20:52	sritchie	will do
20:53	abp`	ohpauleez: Had that error too. Quite a while ago.
20:53	ohpauleez	abp`: With shoreleave-remotes?
20:53	ohpauleez	or just in general
20:53	abp`	ohpauleez: Yep
20:53	abp`	shoreleave-remotes.http_rpc
20:54	ohpauleez	hmm, I'll try some things with baseline and see if I can get it repro
21:08	pppaul	how can clojure cure my sleep deprivation?
21:10	brehaut	(count (repeat :sheep))
21:11	brehaut	when that returns, you'll probably be sleepy
21:11	abp`	pppaul: It hardened mine out. To much things to try, to mich code to write.. :(
21:13	pppaul	i must find more uses for (diff)
21:14	abp`	3am here, experimenting with graph visualizations
21:14	warz	hm idk about this but in this one code file of mine, im calling a function that doesnt exist but the error is wrong number of args passed, instead of no function found or something like that.
21:14	warz	probably because im using "lein ring server", and it think the function is still there, or something.
21:14	warz	because it was, but i renamed it.
21:15	brehaut	warz presumably you have reloaded the namespace?
21:15	warz	well i think ring does that on its own? it seems to reload everything else
21:15	mattmoss	~coffee
21:15	clojurebot	Gabh mo leithscéal?
21:15	abp`	Yeah, another case of lein ring not reloading properly..
21:15	mattmoss	o_O
21:16	brehaut	warz: ring doesnt do that by itself, though i think lein-ring includes that middleware itself.
21:16	abp`	I think it stumbles when errors occur until they are fixed. At times I just restart lein ring to get the right traces or a working app.
21:17	abp`	But often I glance at the trace or my last written code and know what I messed up. :)
21:18	lazybot	Raynes: I feel bad
21:19	warz	yea i mean it was definitely just some funkyness in it reloading while i was editing, and continuning to edit caused it to work itself out
21:20	abp`	yup. Sometimes you can refresh the page like mad till the stacktrace goes away and you get and old working version of the app.
21:23	sritchie	do you guys know how to serve images in compojure?
21:24	augustl	sritchie: there's a built-in ring middleware for serving all files in a directory on the classpath
21:24	augustl	ring.middleware.resource
21:24	sritchie	augustl: I'm actually requesting an image from another service,
21:24	abp`	sritchie: Or (compojure.route/resources "/")
21:24	sritchie	and passing it directly through to my user
21:25	sritchie	which is obviously inefficient, but I'm mocking out a map tile server
21:25	sritchie	so for now, I'm just getting my tiles from another tile server --
21:25	maleghast	I am feeling very n00b-esque this evening, but… If you had a large(isn) vector of maps and you wanted to find a specific map, how would you do it?
21:25	sritchie	then I'll replace that back end with a thrift database
21:26	sritchie	augustl: just not sure how to properly pass the value through.
21:26	abp`	maleghast: Probably (some (fn [m] (when (thats-it? m) m)) maps)
21:27	maleghast	abp`: Hmmm… Yeah. I was hoping for something more convenient, I must admit...
21:28	xeqi	sritchie: are you setting the content-type, say with ring.util.response/content-type ?
21:29	abp`	maleghast: You were asking how to find some map. ;)
21:29	ohpauleez	maleghast: (some #{the-map} [all-the-maps])
21:30	ohpauleez	sets are functions
21:30	maleghast	abp`: Yes, but I have around 150 maps in a vector and I want find a single map based on the value of one of its keys. It would be great if there was a way to do this easily...
21:30	ohpauleez	that is O(n)
21:30	abp`	xequi sritchie aren't wrap-file-info, wrap-head and probably wrap-content-type what he wants?
21:31	sritchie	that looks right
21:31	maleghast	ohpauleez: Ok, that'd work if I knew the complete map, but I only have one value - so I know all the keys and only one value.
21:31	jeremyheiler	maleghast, do you want to know if the value is not nil, or something specific?
21:31	ohpauleez	maleghast: partial-map and unify it
21:31	ohpauleez	using core.logic
21:31	abp`	lol
21:32	xeqi	abp`: I had the impression those only helped with files/resources, they might be sufficent
21:32	maleghast	ohpauleez: Ok… I was looking for simple.
21:32	ohpauleez	that is, by the very definition, simple
21:32	ohpauleez	perhaps not easy :)
21:32	ohpauleez	you can also just use (keep)
21:32	ohpauleez	and look for the key/value
21:32	abp`	xeqi: Well, looking at there: https://github.com/weavejester/compojure/blob/1.1.3/src/compojure/route.clj#L26 it's only underpinning file/resource related things but seems like the way to go
21:33	ohpauleez	and it'll keep the entire map
21:33	maleghast	ohpauleez: I know what you mean ;-) Thanks :-)
21:33	ohpauleez	,(doc keep)
21:33	clojurebot	"([f coll]); Returns a lazy sequence of the non-nil results of (f item). Note, this means false return values will be included. f must be free of side-effects."
21:33	abp`	,(doc some)
21:33	clojurebot	"([pred coll]); Returns the first logical true value of (pred x) for any x in coll, else nil. One common idiom is to use a set as pred, for example this will return :fred if :fred is in the sequence, otherwise nil: (some #{:fred} coll)"
21:33	abp`	Now guess whats more efficient. :P
21:33	maleghast	sure
21:34	pocho	Is there a function that takes a map and a function and replaces each value in the map with a value determined by the function?
21:34	ohpauleez	pocho: That seems like you just want to use (map …), no?
21:35	pocho	wait I think I want fmap
21:35	pocho	So many functions to remember.
21:35	ohpauleez	yeah fmap is a good call, there's a ML thread about this
21:36	ohpauleez	https://groups.google.com/forum/?fromgroups=#!topic/clojure/PsyR-_Hp9Cg
21:38	yedi	i'm really loving the fact that my vars can have non alphanumeric characters in the name
21:38	brehaut	,(apropos
21:38	clojurebot	#<RuntimeException java.lang.RuntimeException: EOF while reading>
21:38	brehaut	,(apropos 'map)
21:38	clojurebot	(sorted-map ns-unmap zipmap mapv map ...)
21:38	brehaut	,(doc mapv)
21:38	clojurebot	"([f coll] [f c1 c2] [f c1 c2 c3] [f c1 c2 c3 & ...]); Returns a vector consisting of the result of applying f to the set of first items of each coll, followed by applying f to the set of second items in each coll, until any one of the colls is exhausted. Any remaining items in other colls are ignored. Function f should accept number-of-colls arguments."
21:40	TimMc	OK, conjing this to my wishlist: Find all the free variables in an s-expression in Emacs.
21:40	TimMc	(to help with refactoring)
21:40	brehaut	TimMc: +1
21:40	TimMc	Totally feasible, yeah?
21:40	yedi	what is a free variable?
21:41	TimMc	One which is not bound. :-)
21:41	brehaut	TimMc: seems like it. i wonder if there is a kibit rule (not that kibit is working for me)
21:41	barry_	Hi all. I've been banging my head against this for a day, and am hoping there's a lobos guru in the house...
21:41	yedi	also when using the -> macro, if i have parens around a function call would it work the same as without
21:41	barry_	If I aot any modules in my project, lobos fails to find lobos.migrations.
21:41	adu	hi barry_
21:42	barry_	(i.e. call to lobos.core/migrate does nothing)
21:42	barry_	Removing the :aot from my Leinagen 2 project.clj, and everything's great.
21:42	jeremyheiler	yedi, it will work. usually you only add parens for the 2nd or more args.
21:42	yedi	for example, are these equivalent?: (-> "a b c d" .toUpperCase) (-> "a b c d" (.toUpperCase))
21:42	yedi	jeremyheiler: ah ok, thanks
21:42	TimMc	brehaut: I guess I don't want the free variables, actually -- what I really want is a list of lexical bindings that an s-expression uses.
21:43	TimMc	Perhaps if their binding sites could be highlighted...
21:43	jeremyheiler	yedi, np
21:44	barry_	hi adu
21:45	warz	im trying to debug an error, and i think its because i dont know how to do variable arity functions. the error looks like its running all of the code in this function instead of just the one with no params: https://gist.github.com/ryancole/5001570
21:45	warz	am i doing that incorrectly, or is there actually an error in clutch? (i dont think there is because im pretty sure ive done this exact query in simpler code)
21:46	brehaut	warz: you have multiple arities correct i think
21:46	warz	hrm, ive got something wrong then, i bet. maybe clutch doesnt take the database as a first param like that, but i could have sworn it could.
21:46	brehaut	warz: something in clutch is chucking that exception
21:47	brehaut	warz: it can do, or you can dynamically bind it
21:47	brehaut	warz: it looks are you meaning to call id?
21:47	warz	hm i wonder if its because theres only 1 result and im using map
21:48	brehaut	oh, i wonder if its because db is not a url
21:48	brehaut	its a string
21:48	warz	nah ive been using that the whole time and it was working when i was using variable scope db binding
21:48	warz	i thought id take it out and now i get this error
21:48	warz	ill try putting it back in and see if it errors
21:49	brehaut	ok, well looking at the exception soemthing is calling seq on a string and getting chars and then calling nth on that char
21:49	brehaut	warz: (thats a guess)
21:50	brehaut	warz: i think something is expecting a seq of seqs
21:50	brehaut	can you update the gist with an example of the call that is failing
21:51	warz	i updated the gist to include the additional file
21:52	warz	its a ring route handler, and im requesting the one without an id
21:52	warz	well i do have an error in that fikle
21:52	warz	but i dont think itd be being called
21:53	brehaut	warz: https://gist.github.com/ryancole/5001570#file-foo-clj-L10 do you really mean to be calling {:key (id)} rather than {:key id} ?
21:54	brehaut	warz: i dont think its actually in your codepath atm but that does look like a bug anyway
21:54	brehaut	warz: not to mention, you are calling all-items with an id in you route, when i think you want to be calling single-item
21:54	warz	yea thats most likely an error. it was originally :keys.
21:55	warz	yea, thats what i was mentioning earlier about the error. i adjusted that and updated the gist incase you hadnt hit it, yet.
22:00	warz	well i think youre right about the url
22:00	warz	i think clutch/with-db accepts a string
22:00	warz	but clutch/get-view does not
22:00	warz	it works if i move back to with-db
22:01	brehaut	right, https://github.com/clojure-clutch/clutch/blob/master/src/com/ashafa/clutch.clj#L26-L35 looks like its translating it if needed there
22:01	augustl	sritchie: the :body of a ring response can be streams
22:03	sritchie	gotcha
22:09	adu	augustl!
22:09	augustl	yo
22:31	pppaul	sometimes i find using clj-http much easier than using clutch
22:39	muhoo	ok, i'm going in, to try to get piggieback working with a browser cljs repl in nrepl.el. i may not make it out alive. may god have mercy on my soul.
22:41	alandipert	muhoo: we're all rooting for you. that would be excellent.
22:44	xeqi	muhoo: I've had it work before, it was awesome to control a webgl renderer from emacs
22:44	technomancy	has anyone hooked it up to gecko's internals yet?
22:45	technomancy	like in the context of the browser itself rather than the page?
22:46	xeqi	technomancy: ?
22:50	pbostrom	muhoo: I spent some time getting it to work recently, one caveat: piggeback has a dep on an old version of the Closure compiler, so if you're using cljsbuild it's going to pick up the old version
22:51	abp`	pbostrom: Can't circumvent that via exclusions?
22:52	muhoo	c
22:52	pbostrom	abp`: I'm not familiar with exclusions
22:52	muhoo	run lein-pedantic, it'll tell you all about it :-)
22:53	abp`	pbostrom: You can exclude dependecies of your dependencies to pull in newer versions
22:53	abp`	pbostrom: Like that: https://github.com/technomancy/leiningen/blob/master/project.clj#L14
22:54	abp`	muhoo: Thanks for reminding me to use pedantic. :)
22:54	pbostrom	abp`: cool, thanks let me give that a shot
22:55	abp`	pbostrom: As muhoo said, https://github.com/xeqi/lein-pedantic
22:55	xeqi	muhoo: haha
22:55	muhoo	xeqi: didn't realize that was yours. nice work.
22:57	brehaut	huh. im already using pedantic apparently.
23:03	ibdknox	warz: you were asking about LT. Next thursday 0.3.0 will drop
23:03	warz	awesome! :D
23:04	ibdknox	it's why I've been... sparse
23:04	warz	well, i use it every day so im looking forward to it. :)
23:04	ibdknox	this will be a night and day difference
23:05	warz	based on the few adjustments that i asked about and you said were changing, even those would be awesome
23:05	warz	so yea im excited
23:15	ChongLi	am I alone in this little train of thought?:
23:15	ChongLi	cljs on cljs -> light table sans jvm -> light table on chrome os
23:16	ChongLi	would make for a fantastic developer machine
23:17	technomancy	xeqi: well I'm not really interested in using cljs for making web sites, but my browser is written in JS, and it sucks to have to use that to extend it
23:22	callenbot	technomancy: you could use cljs to write browser extensions. If that's not what you meant by "extend it", what do you want to do?
23:44	yogthos	callenbot: indeed :)
23:45	callenbot	yogthos: you weren't supposed to agree :(
23:45	yogthos	lol
23:45	yogthos	if we're talking about error reporting in cljs compiler, it could use some work to say the least :P
23:45	muhoo	hmm, well, almost. lockus replus: https://www.refheap.com/paste/11578
23:47	pbostrom	muhoo: did you refresh your page in the browser after you started the repl?
23:47	muhoo	nope, i know not to do that :-)
23:48	pbostrom	no, you do need to do that
23:48	muhoo	oh? hmm, ok.
23:48	muhoo	i've blown away repls by reloading before.
23:49	pbostrom	the repl listens on port 9000, then you have to load the page with the bit of cljs that sets up the long polling connection to that port
23:51	muhoo	ok, that makes sense. cljs repl starts the server
23:51	muhoo	also, it hates advanced mode: "Uncaught TypeError: Cannot read property 'bf' of undefined " whitespace no such problem
23:52	muhoo	haha WARNING: Wrong number of args (0) passed to cljs.core/array at line 127 file:/usr/local/share/java/lein-repos/repository/org/clojure/clojurescript/0.0-1586/clojurescript-0.0-1586.jar!/cljs/core.cljs
23:53	muhoo	ok, that's enough fun for tonight. didn't expect to get it working, but that was pretty close.
