#clojure – 2014-02-09

2014-02-09

00:32	ivan	I fixed the pygments clojure lexer but now everything looks worse when the specials list only includes specials
00:32	ivan	now I have to come up with elaborate rationale for a list of builtin macros to highlight as a pygments Keyword instead of a Name.Builtin
00:34	ivan	bindings_and_control_flow = [...]
00:41	dsrx	any way I can use destructuring to bind to the last several elements of a sequence?
00:41	dsrx	something like [[& _ x y] [1 2 3 4]]
00:41	dsrx	where i'd like x and y to be bound to 3 and 4
01:01	xuser	dsrx: you can use map destructuring in that case
01:02	xuser	dsrx: [{x 2 y 3}
01:02	quizdr	xuser i suppose you mean where 2 and 3 are the index keys, right?
01:02	xuser	[{x 2 y 3} [1 2 3 4]]
01:02	xuser	quizdr: yes
01:02	quizdr	but what if you don't know how long the args list is? I suspect that's what dsrx is asking
01:03	quizdr	in which case i'd think you just get the entire collection as a single binding, and call collection functions to get the last couple elements [& everything]
01:06	xuser	quizdr: yeah, I guess you can pull the values from the collection in the bingding vector
01:16	quizdr	xuser what i mean i don't know if you can actually do what dsrx in the destructuring, you'd have to call functions on your entire passed collection list within the function definition
01:17	quizdr	although i know destructing can be a deep minilanguage on its own so i might be overlooking an obvious solution
05:26	piranha_	damn, somehow core.async fails me in advanced compilation mode :(
05:51	piranha_	is the author of sablono here? :)
08:17	voldyman	any recommendations for caching data in a web server?
08:18	mercwithamouth	ok '(blah) vs (list blah) (list ...) evaluates they say. can someone sort of help me out here? i'm not even sure what to ask
08:19	llasram	mercwithamouth: Well, what are you trying to understand?
08:19	d11wtq	mercwithamouth: What's the question? '(blah) is equivalent to (list 'blah), but (list blah) is the list of variable "blah".
08:20	llasram	,(read-string "'(blah)")
08:20	clojurebot	(quote (blah))
08:20	scottj	,(let [blah 1] ['(blah) (list blah)])
08:20	clojurebot	[(blah) (1)]
08:21	llasram	haha, too many teachers in the classroom
08:21	d11wtq	,(= '(blah) (list 'blah))
08:21	clojurebot	true
08:21	mercwithamouth	lol
08:21	mercwithamouth	overload
08:21	mercwithamouth	(list ...) allows you toevaluate...but evaluate what?
08:22	mercwithamouth	,(count '(1 2 3))
08:22	clojurebot	3
08:22	mercwithamouth	,(count (list 1 2 3))
08:22	clojurebot	3
08:22	d11wtq	mercwithamouth: (list ...) allows you to interpolate variables into lists, effectively.
08:22	llasram	Er
08:22	d11wtq	mercwithamouth: While '(... ) quotes the entire list.
08:22	llasram	I think starting a little earlier might help
08:22	mercwithamouth	ah! ok
08:23	llasram	Code is data. We store the data as strings. The reader translates strings into data.
08:23	mercwithamouth	well i gotcha. i'm reading programming clojure and clojure in action. i'm just going through http://java.ociweb.com/mark/clojure/article.html so i decided to stop and see what they meant
08:23	llasram	,(read-string "'(blah)")
08:23	clojurebot	(quote (blah))
08:23	llasram	,(read-string "(list blah)")
08:23	clojurebot	(list blah)
08:23	llasram	The compiler is what turns data into code
08:24	voldyman	mercwithamouth: braveclojure.com explains these things pretty nicely.
08:24	mercwithamouth	voldyman: ahh yeah, i have that site in my bookmarks as well
08:25	voldyman	its what helped me go from 0 - a simple website in a week
08:25	voldyman	and #clojure is always helpful
08:25	mercwithamouth	i'll go ahead and work my way through it today. i suppose it would help if i didn't jump around
09:32	AeroNotix	Did anyone get JSVC working with Clojure apps? https://github.com/clojure-cookbook/my-daemon/issues/1
09:32	AeroNotix	The cookbook claims to have this working, but I can't get it to on my system.
09:33	AeroNotix	I can't even get the example project to run? Same error with my personal projects.
09:41	AeroNotix	if I `jar -tf $MY_UBERJAR` then it has the class in it!
09:41	AeroNotix	huh
09:42	AeroNotix	I've tried lein-daemon but for some reason it hangs on my CI server and never starts
09:44	AeroNotix	any ideas guys/gals?
09:45	AeroNotix	how do you guys daemonize your Clojure applications?
09:48	hyPiRion	AeroNotix: http://www.rkn.io/2014/02/06/clojure-cookbook-daemons/ has a tutorial on that.
09:48	AeroNotix	hyPiRion: please look at the link I posted, I already said I'm following _that_exact_thing_
09:49	AeroNotix	I get the same error with the code associated with that blog post and my own projects
09:49	benzap	Is there an article out there outlining the several different clojure web frameworks / methods of deployment?
09:49	benzap	I'm having a really hard time finding something I like
09:53	AeroNotix	hyPiRion: could you try running this locally? It takes like 2 minutes to try\
09:57	llasram	AeroNotix: I daemonize Clojure applications by building uberjars then running them under an init system (runit), essentially as with any other language
09:57	hyPiRion	AeroNotix: wish I could, but I'm away from work computer now
09:57	AeroNotix	hyPiRion: ok
10:08	piranha_	dnolen: here by any chance?
10:26	hyPiRion	AeroNotix: perhaps try what llasram suggested instead?
10:26	AeroNotix	What did he say?
10:27	AeroNotix	hyPiRion: ^
10:27	hyPiRion	"I daemonize Clojure applications by building uberjars then running them under an init system (runit), essentially as with any other language
10:27	llasram	AeroNotix: Haha, I un-/ignored you, but you have me /ignored ?
10:27	hyPiRion	"
10:28	AeroNotix	llasram: I don't, nor have ever /ignored you
10:28	llasram	Fair enough then
10:28	AeroNotix	llasram: the problem with that is, how to programmatically do it in a sane way with CI?
10:28	AeroNotix	I want to run acceptance test suites, essentially just running the jar, then my external test suite, then killing the server.
10:29	AeroNotix	At the moment, I hacked together a Python script to spawn the server, then the test suite and then recursively kill the process tree
10:29	AeroNotix	due to the jar forking plenty of proceses
10:29	AeroNotix	processes
10:29	AeroNotix	lein-daemonize worked locally, but failed to start on my jenkins server, and it's annoying to debug. So I looked into other methods
10:29	llasram	I see... Maybe just build the uberjar and spawn that as the service then? Should match what you'd end up doing in production
10:31	technomancy	(inc uberjars+runit)
10:31	lazybot	⇒ 1
10:31	AeroNotix	llasram: I'd like to get the daemon working since this would also help our ops team with making services
10:31	llasram	heh
10:31	AeroNotix	since it seems to allow arbitrary code execution when stopping/killing services
10:32	llasram	AeroNotix: What init system are you using? I guess I'm not following what differentiates a script launching the JVM w/ an uberjar from a service
10:32	technomancy	self-daemonizing processes usually involve a lot of wheel-reinventing
10:32	AeroNotix	llasram: the fact that it blocks, and needs killing, for a start.
10:32	AeroNotix	technomancy: exactly why I want to use apache daemon
10:32	technomancy	AeroNotix: eh; apache just NIH'd it too
10:33	technomancy	this stuff is a ton simpler if you do it outside your process
10:33	AeroNotix	llasram: in production? Not sure, tbh. The ops team uses Ubuntu, so whatever Ubuntu uses I guess?
10:33	technomancy	that'd be upstart
10:33	technomancy	clojars uses upstart
10:33	AeroNotix	I'll take your word for it, I don't touch ubuntu
10:33	technomancy	it's not great, but it is simple
10:33	AeroNotix	Why isn't this a solved problem though?
10:33	AeroNotix	technomancy: you work for Heroku, what do they use?
10:33	technomancy	hm; I don't see that it isn't
10:34	technomancy	AeroNotix: an out-of-process daemonization system =)
10:34	technomancy	https://github.com/ato/clojars-web/blob/master/SYSADMIN.md
10:34	technomancy	hm; I guess that doesn't give the exact upstart config
10:34	llasram	AeroNotix: upstart works with processes which do not daemonize themselves. In my experience, that model is simpler for everyone
10:34	AeroNotix	the other thing is, I want a solution which can work in isolation, cross platform and on-demand. It's a lot to ask for, I know. Our developers use a mix of MacOSX and Linux, so a pure Java solution would be perfect.
10:35	llasram	development OS != production OS -> madness
10:35	AeroNotix	llasram: don't the majority of developers use MacOSX these days?
10:35	llasram	Especially with all the options (vagrant etc) to make them match
10:35	technomancy	(inc *1)
10:35	lazybot	⇒ 2
10:35	technomancy	oops race condition
10:36	llasram	haha
10:36	technomancy	AeroNotix: lots of macosecksists just use it as a platform on which to run linux for development
10:36	AeroNotix	technomancy: this sounds like madness, as far as I am concerned. But that's for another day.
10:37	AeroNotix	Regardless, did anyone try the my-daemon demo app?
10:37	technomancy	you'll never get things to work the same
10:37	llasram	AeroNotix: You can run whatever you want on your development system as the bare-metal OS, but the code you're developing should run in development under the close-as-possible env to what you run in production
10:37	AeroNotix	llasram: I get that. It's a nice idea to strive for.
10:37	AeroNotix	vagrant isn't a panacea
10:37	AeroNotix	nor is docker
10:38	AeroNotix	Running things locally is fine for a whole slew of languages/platforms
10:38	llasram	No, but they're both better than "it works under OS X" :-)
10:38	AeroNotix	llasram: I don't run things on OSX
10:38	AeroNotix	My development machine is Linux.
10:38	technomancy	the effort it takes to try to get the exact same version numbers across OSes is an ongoing time suck; getting a production-like env on your laptop is a one-time up-front cost that pays back over time
10:38	llasram	(inc technomancy)
10:39	lazybot	⇒ 97
10:39	AeroNotix	I'm not arguing with that
10:39	AeroNotix	but there are other factors at play here
10:39	AeroNotix	namely, political issues regarding getting mac users to put down their shinies
10:39	technomancy	=\
10:40	AeroNotix	I'm introducing clojure at my workspace with a periphery project. I want to make it as seamless as possible
10:40	AeroNotix	Lein has gone a long way, especially in contrast with Rebar
10:40	AeroNotix	But Erlang comes with releases, which allow the developer to not even realise that application daemonizing is a thing
10:41	AeroNotix	so I want to have something which I can literally have "app {start,stop}"
10:41	AeroNotix	which Erlang has, and I'm sure is possible in Clojure/JVM land
10:42	hyPiRion	Q: Do people tend to define all records in the same namespace in an application?
10:43	llasram	hyPiRion: Elaborate?
10:43	AeroNotix	technomancy: so how do you guys do CI/testing?
10:43	AeroNotix	with Clojure applications
10:43	hyPiRion	llasram: I want to define a couple of records. Should I put them all in the same for namespace? They're essentially just used as structs.
10:43	llasram	AeroNotix: In Turing, all things are possible. I consider what you've described undesirable, and thus have no experience with to suggest options :-)
10:44	AeroNotix	llasram: which aspect is undesireable?
10:44	llasram	AeroNotix: Processes daemonizing themselves
10:44	AeroNotix	llasram: Erlang gives you the option
10:45	technomancy	AeroNotix: when I was using clojure we just used jenkins
10:45	llasram	Sure. And maybe it makes sense for Erlang in historical context. I don't think it's a good way to think about services on current Unix-y distros
10:45	AeroNotix	technomancy: great, we're using Jenkins. Can you give me any more information?
10:46	technomancy	AeroNotix: there wasn't really anything clojure-specific about our setup
10:46	AeroNotix	technomancy: so what did you do for testing e.g. REST endpoints or some other http listener?
10:46	AeroNotix	I want to do end-to-end testing
10:46	technomancy	we just had a bin/setup script in the repo that would pull in apt-get dependencies and a bin/ci script that would kick off the CI run
10:46	technomancy	the system I worked on was an AMQP worker
10:47	llasram	hyPiRion: Ah. I don't use defrecord much... Interesting question
10:47	technomancy	AeroNotix: FWIW the platform independence thing is different on erlang; they have a strong motivation not to rely on anything outside the BEAM VM for reliability reasons which simply arent' present on the JVM
10:47	technomancy	but I understand that decisions like that can't always be made for technical reasons
10:48	AeroNotix	technomancy: it's part of it, but there's a whole deployment / upgrade philosphy around Erlang where it makes sense. It just doubles as a succinct way to test things.
10:49	technomancy	AeroNotix: but as far as organizing our code, we had a primary entry point as a -main invoked via an uberjar, and then some admin helper namespaces also done as -main defns
10:49	AeroNotix	technomancy: so, did you spawn these processes off and then run tests/
10:49	AeroNotix	?
10:50	technomancy	AeroNotix: oh, no the tests were just `lein test` affairs. we didn't do any fully end-to-end tests
10:50	AeroNotix	technomancy: ok, cool
10:50	AeroNotix	https://gist.github.com/AeroNotix/db274b8e6863a412de0a
10:50	AeroNotix	I'm using this at the moment
10:51	benzap	Hey guys, i'm trying to include other directories for the ring-server to monitor, and i'm not really certain on the relative path
10:51	benzap	does this look correct? http://cljbin.com/paste/52f7a2cbe4b014e0a4429c5e
10:51	benzap	I have a folder resources with a template folder, with templates
10:51	benzap	and then i'm still referencing my src directory
10:52	benzap	i've found that it still works with my handler in the src directory, but modifying my templates don't have any effect
10:58	technomancy	AeroNotix: seems reasonable
11:02	ornicar	hello there!
11:03	ornicar	I've been trying and googling for long enough now, time to try asking #clojure :P
11:04	ornicar	I have 2 async channels, I want to wait and do something when both chans have outputed a message.
11:04	ornicar	I've been trying merge, but it gives me only the first message sent by the channel that completes the faster
11:04	ornicar	(<! (merge chan-a chan-b)) ; I get the message of whatever chan outputs first
11:05	ornicar	what I want is:
11:05	ornicar	(let [[a b] (<! (??? [chan-a chan-b]))
11:06	ornicar	where ??? is the function I'm looking for.
11:06	ornicar	does it make sense?
11:15	llasram	ornicar: Don't you just want (let [a (<! chan-a), b (<! chan-b)] ...)
11:16	ornicar	I don't know which one will return first.
11:16	ornicar	does it matter?
11:17	AeroNotix	TIL you can merge channels
11:17	llasram	Oh, I guess it could, because of fixed-size queues
11:17	llasram	I haven't actually used core.async yet, so can comment no further :-)
11:18	AeroNotix	ornicar: alts?
11:19	ornicar	no, alts! behaves like merge in this case
11:20	AeroNotix	do you need to know which channel the message came from?
11:20	llasram	But doesn't alts! let you know the channel? Then you just wait on the other one
11:20	ornicar	afaik, (<! (merge [a b])) is similar to (alts! [a b])
11:20	ornicar	except, yes, you know the chan
11:21	ornicar	well I can hack my way around, but I wanted to know if there was a standard solution to this, imo, common problem: parallelism.
11:21	clojurebot	Pardon?
11:48	tpope	bbloom: is it just (comment ...) stuff tripping you up?
11:48	bbloom	tpope: yeah, getting used to it a bit, but as you know, it's hard to retrain your fingers :-)
11:49	bbloom	tpope: also my workflow has changed a bit over time
11:50	bbloom	tpope: i used to re-eval individual defs a bunch, but now i just cpr the whole file
11:50	bbloom	tpope: my workflow used to involve re-evaling top-levels a lot back when i used tmux hackery to emulate real repl integration, but when you released foreplay, i no longer had to do that
11:51	bbloom	tpope: since then, i've basically stopped evaluating top levels, since cpr is so easy to do
11:53	bbloom	the only time i really have to eval a top level form is if i'm changing a definition in namespace with deftypes or defprotocols other than the namespace i'm currently working on
12:13	ambrosebs	for those core.typed + vim users out there https://github.com/typedclojure/vim-typedclojure
13:33	bacon1989	Hello, i've been trying to get a simple development server running clojure for a while now, and i'm having a hard time getting some more advanced functionality working
13:33	bacon1989	I tried following this example http://stackoverflow.com/questions/1665760/compojure-development-without-web-server-restarts
13:33	bacon1989	and made a few changes into this http://cljbin.com/paste/52f7c8b4e4b0f2c6653e9f1d
13:34	bacon1989	i'm able to get the web-server running just fine, but the wrap-reload line doesn't seem to be working
13:34	bacon1989	i've even been running the server within the repl, which means the evaluating certain things, like the main-routes, should have changed the web-server's main-routes variable, no?
13:36	technomancy	ambrosebs: have you seen https://github.com/technomancy/nrepl-discover ?
13:37	technomancy	I would like to see more tooling like that happen in an editor-agnostic way
13:39	bacon1989	Has no one here ever set up a clojure web server?
13:40	technomancy	bacon1989: if it's not picking up reloads then probably you need to pass a var to run-jetty instead of a function
13:40	technomancy	(just a guess; that's the common mistake)
13:42	bacon1989	so I should change my defn app to an def app, etc?
13:43	technomancy	bacon1989: yeah, and do (run-jetty #'app ...)
13:44	bacon1989	technomancy: oh nice, that did the trick
13:44	technomancy	vars are great
13:44	bartxx	Maybe this time I'll have more luck (sory for asking same question 3rd time): is there any way to extract and save (to file for example) state of core async's "go" state machine?
13:44	bacon1989	that's interesting, I wonder if I should respond to that stack overflow article, and update it
13:58	clojuredood	hey guys.. just wondering what a concise way is to check if string starts with any one of a collection of substrings ?
14:08	clojuredood	I suppose I'm basically hoping I can supply a set to a 'startsWith' alike function
14:08	clojuredood	any ideas ?
14:09	fowlslegs	clojuredood: are the substrings of variable length?
14:09	clojuredood	yes
14:10	clojuredood	is regex the best way to go instead ?
14:10	systemfault	some + startsWith (I'm a noob so don't trust me)
14:10	clojuredood	systemfault: I don't understand that sorry
14:11	systemfault	http://clojure.github.io/clojure/clojure.core-api.html#clojure.core/some + String.startsWith ?
14:12	fowlslegs	Maybe something like this
14:12	fowlslegs	Actually hold on
14:12	clojuredood	systemfault: I begin to see thanks
14:13	sdegutis	Do you have to manually convert a clojure.lang.PersistentVector into a System.Collections.Generic.IEnumerable?
14:14	sdegutis	I thought since the first is concrete and the second is an interface, it wouldn't need a conversion.
14:14	sdegutis	But then I see: Unable to cast object of type 'clojure.lang.PersistentVector' to type 'System.Collections.Generic.IEnumerable`1[System.String]'.
14:22	fowlslegs	)
14:23	fowlslegs	(for [x (range 1 longest prefix)] (if #(some (apply str (take x "string")) prefixlist) (apply str (take x "string"))))
14:23	fowlslegs	^clojuredood
14:23	clojuredood	fowlslegs: thanks! I will take a look now
14:26	pyrtsa	fowlslegs: What was that supposed to do? o_O
14:29	fowlslegs	(def stringlist '("p" "f" "li" "far"))
14:30	logic_prog	I thought I was going to get some work done today. Then, I stumble across http://www.youtube.com/watch?v=Y8gttn9xmtA
14:30	fowlslegs	(def stringlist '("p" "f" "li" "far"))
14:30	fowlslegs	(for [x (range 1 4)] (let [prefix (apply str (take x "fargo"))] (if (some #(= prefix %) stringlist) prefix)))
14:30	fowlslegs	clojuredood pyrtsa ^^
14:30	pyrtsa	To find which prefix matched?
14:31	fowlslegs	Yeah
14:31	fowlslegs	clojuredood asked for a simple way. I am pretty new to Cloj, but that's what seemed most simple to me.
14:31	pyrtsa	,(first (filter #(.startsWith "fargo" %) '("p" "f" "li" "far")))
14:31	clojurebot	"f"
14:32	clojuredood	folwslegs: you've given me a boost... gave me some ideas... I've got as far as : (some #(if (.startsWith some-string %) true false) prefixes)
14:32	clojuredood	seems to be working so far
14:32	clojuredood	thanks!
14:33	fowlslegs	I wonder if that java function is performing the same comparisons as my fn.
14:33	pyrtsa	clojuredood: The (if ... true false) is redundant though. Just do #(.startsWith ...) there.
14:33	clojuredood	pyrtsa: awesome, another refinement
14:34	pyrtsa	,(some #(.startsWith "fargo" %) '("p" "f" "li" "far"))
14:34	clojurebot	true
14:36	clojuredood	lol, clojure is just awesome
14:36	fowlslegs	My fn ran in .33ms vs .11ms for pyrtsa
14:36	pyrtsa	If the list of substrings is a compile-time constant, you can just use e.g. ##(re-find #"^(?:p\|f\|li\|far)" "fargo")
14:36	lazybot	⇒ "f"
14:36	clojuredood	thanks guys
14:46	fowlslegs	pyrtsa: I'm new to regex. Would you enlighten me as to how to alter the above function s.t. "f" and "far" are returned.
14:49	pyrtsa	fowlslegs: Doesn't sound like a problem that you'd tackle with (one) regex anymore.
14:49	fowlslegs	Yeah I thought that too and was trying to figure out the re-find/re-matcher relationship.
14:50	pyrtsa	fowlslegs: ##(keep #(re-find % "fargo") [#"^p" #"^f" #"^li" #"^far"])
14:50	lazybot	⇒ ("f" "far")
14:53	fowlslegs	So in the original ^ means "starts with" and x\|y means "find x or y", but why the ?:
14:53	pyrtsa	The regex part of clojure.core is a bit limited, by the way. It doesn't expose a way of finding where the pattern matched in the string, only whether and what it matched.
14:54	pyrtsa	fowlslegs: The (?: ... ) is a non-capturing block.
14:54	pyrtsa	If you omit the ?:, it turns into a capturing one, and -- somewhat surprisingly -- re-find starts to return vectors instead of strings.
14:55	fowlslegs	Yeah I noticed.
14:55	pyrtsa	Vectors containing both the whole match as well as the captured blocks (one or many).
14:55	pyrtsa	I don't think it's the prettiest API design, but it's pretty common practice in many dynamic languages.
14:56	fowlslegs	I don't see anything about non-capturing blocks on the oracle regex doc http://docs.oracle.com/javase/tutorial/essential/regex/index.html
14:56	fowlslegs	maybe I just skipped over it.
14:56	pyrtsa	fowlslegs: http://docs.oracle.com/javase/7/docs/api/java/util/regex/Pattern.html
14:56	pyrtsa	"(?:X) -- X, as a non-capturing group"

15:54	steckerhalter	if I fetch some content from url and store that in a variable (I will update it from time to time), what should I use? atom/ref/..
15:55	llasram	steckerhalter: Depends on the update model, but it sounds like an agent could be appropriate
16:09	steckerhalter	llasram: ok, I'll try that, thanks
16:09	akyte`	Can clojure/android handle intents without issue?
16:50	Krajsnick	Is it possible getting code completion for Clojure and imported deps within Vim?
17:49	seangrove	I have a bunch of :style attributes I need to modify in an emacs buffer. I wrote a clojure function that does what I want for each individual one. I then recorded an emacs macro that finds the next :style attribute, cuts it, switches to the clojure repl, transforms it into the desired for, then copies the new form back into the original location
17:50	seangrove	The problem is, it always fails on copying the result from the repl. I think ti could be a race condition, where the macro step to copy the resultant form runs before the repl can return, so it copies the wrong thing. Any tips on how to do this in a cleaner way?
17:53	llasram	seangrove: The communication between emacs and the nrepl server is async, so that's almost certainly what's happening. I don't have any good ideas on how to fix w/o just writing some elisp to call into the nrepl server yourself though
17:54	seangrove	llasram: Yeah, I'm not clear on how to do that either. Probably a good idea long term to figure it out though. Any idea if it's clean/simple enough?
17:54	seangrove	Maybe I should just write the function in elisp
17:55	llasram	The functions looked straightforward when I've poked around, but I haven't actually tried to do anything like what you're describing myself
18:18	seangrove	llasram: The hack for today is just M-: (sleep-for 0.25)
18:32	greghendershott	Is HEAD wonky? I pushed a commit that only fails HEAD (not 4 other vers inc 5.92): https://travis-ci.org/greghendershott/rackjure/builds/18548966
18:33	greghendershott	and fails it with SIGSEGV MAPERR https://travis-ci.org/greghendershott/rackjure/jobs/18548971 O_o
18:34	greghendershott	... and I'm on the wrong channel ... sorry!
18:34	gfredericks	clojurebot: HEAD is wonky
18:34	clojurebot	Ok.
19:11	scape_	how could i merge a smaller byte array into a larger? or should I do this sequentially with aset-byte?
19:16	hyPiRion	scape_: System/arraycopy perhaps?
19:16	benkay	a test fixtures question: i'd like to spin up a tcp server in the setup phase of my fixture, and tear it down in the teardown phase. to stop this tcp server (aleph) I need to call the function returned when I start the tcp server. would it be idiomatic to (def stop-server (tcp-server {blablabla})) in the setup phase and then (stop-server) in the teardown phase?
19:22	scape_	ill take a look thx hyPiRion
19:25	scape_	benkay: it's somewhat familiar in other frameworks to do that-- I personally don't like it, it'd make more sense to receive some server object/map that you'd pass to a stop-server function. which is how I modeled my tcp server (not using aleph)
23:10	tolstoy	dnolen: Do we need to do something extra to get onMouseOver and so on to work in OM?
23:12	tolstoy	dnolen: Hm. Maybe somehow get the react-with-addons....
23:15	tolstoy	Oh, alas: https://github.com/swannodette/om/issues/59 (22 days ago)
23:32	ambrosebs	technomancy: not aware of nrepl-discover
23:32	ambrosebs	technomancy: love the idea. I'm going to have to reimplement this functionality many times I bet.
23:33	amalloy	benkay: why would you def it rather than just letting it? setup and teardown happen in the same lexical scope for test fixtures
23:35	benkay	so (let [thinger (stuffs)] ... (thinger))
23:35	benkay	?
23:36	amalloy	indeed
23:36	benkay	(defn my-fxt [fn] (let [close-server (open-server)] (fn) (close-server)))
23:38	benkay	yeah that makes a great deal of sense. i think i was assuming that the let'd be the setup phase, and that I'd have to close the let in the setup phase and lose access to the bindings declared therein.
23:38	benkay	thanks amalloy!
23:47	frozenlo`	Is there a `distinct' fn that's like `filter'? (distinct my-fn [coll])
23:48	amalloy	nothing built in, Frozenlock, but of course you can implement distinct-by pretty easily
23:51	Frozenlock	amalloy: ok, thanks
23:54	srruby	Which jdk do you recommend? My server runds debian wheezy. Thanks, John
