2013-09-16

00:27	muhoo	i'm trying to understand the use of instaparse. it seems like it doesn't do tokens, only strings.
00:27	muhoo	sorry , only characters, not even string tokens
00:28	callen	muhoo: https://github.com/chameco/Hitman/blob/master/src/hitman/core.clj ?
00:28	callen	you tokenise anything regex can match.
00:28	callen	Instaparse is a GLL, it handles CFGs and CSGs
00:32	muhoo	ah, i was confusing instaparse wiht parsatron
01:33	wei_	is there a way to selectively disable compojure route definitions based on the value of an atom? defroute is a macro so the usual control structures don't work
01:41	amalloy	wei_: a ring handler is just a function. just write a function that takes a route and some sort of `include?` function that selectively decides whether or not to allow that sub-route to run
01:42	amalloy	(routes a b (only-sometimes (fn [] @enable?) (routes c d e))), where only-sometimes is that thing i said you should write
01:47	wei_	i got it, thanks! my fn returns simply (routes) if the routes are disabled. is that what you would have done?
01:47	wei_	(defn only-in-dev [handler] (if-not @prod? handler (routes)))
01:48	callen	wei_: https://github.com/weavejester/environ
01:49	wei_	I'm using it: (defonce prod? (atom (env :lein-no-dev)))
01:50	muhoo	there's no need to have an atom, just check env
01:51	wei_	oh good point
01:54	coventry`	If it's constant throughout the life of the application, you could wrap the dev defroutes in if statements.
01:57	wei_	my problem with that was if I included nils in the final app-routes, I'd get a NullPointerException
02:02	H4ns	i'm using clojure.test and some of my tests depend on files that i'd like into the test's source directory. is there an idiomatic way to determine the directory where a test's source is located?
02:05	SegFaultAX	Variadic relational operators are so handy.
02:06	noidi	H4ns, add a resource directory that's only available during development and put the files there
02:07	noidi	put something like `:profiles {:dev {:resource-paths ["test-resources"]}}`
02:07	noidi	into your project.clj
02:09	noidi	you can then get a resource URL with (clojure.java.io/resource "my-test-file")
02:12	H4ns	noidi: ah, nice! thank you!
02:49	sontek	Any of you guys doing the clojurecup thing?
02:59	muhoo	clojure.... cup?
03:04	sontek	http://clojurecup.com/
03:19	callen	sontek: I am, I have a project in mind.
03:19	callen	I'm looking for backend, frontend, and designers. I can do backend and frontend but not design.
03:21	callen	muhoo: I'm looking forward to it :)
03:25	lgs32a	where can i find the source code of special forms?
03:25	lgs32a	in the clojure code
03:26	callen	lgs32a: in the repo
03:26	lgs32a	callen: yes i expected it there but couldn't find it
03:27	lgs32a	callen: where is if for example
03:29	amalloy	lgs32a: "special form" means something unimlementable (or unimplemented) in the language itself; it's baked into the compiler or something similar. in clojure, that's Compiler.java
03:30	sontek	callen: I'm hoping to find some people in bay area I can join to hack on something
03:30	callen	lgs32a: you'll see a bunch of things like static final Symbol DEF = Symbol.intern("def");
03:30	callen	lgs32a: special forms are anything reified to the compiler that can't be done in macros or functions.
03:30	callen	sontek: well you know I'm in SF.
03:30	lgs32a	amalloy: ty
03:33	callen	sontek: query me?
03:40	quazimodo	I've started fiddling with clojure. Feels good
03:40	quazimodo	that is all
03:41	callen	quazimodo: good :)
03:41	quazimodo	it was hard not to go the common lisp route. I want to sbcl but no one else does :(
03:42	callen	quazimodo: I came to Clojure from Python and sbcl, you're in good company :)
03:42	quazimodo	i ruby a lot
03:42	quazimodo	not even sure why I'm learning clojure tbh
03:42	quazimodo	i guess it's a pain in the ass to gui with ruby
03:48	clj_newb_2345	if I do (.start (Thread. (fn [] ... ))) and the function throws an uncaught exception, is the Thread garbage colected?
03:48	clj_newb_2345	or does it lie around ?
03:51	amalloy	$google java thread uncaught exception
03:51	lazybot	[Thread.UncaughtExceptionHandler (Java Platform SE 7 )] http://docs.oracle.com/javase/7/docs/api/java/lang/Thread.UncaughtExceptionHandler.html
03:52	clj_newb_2345	this says nothing about garage colelction :-)
03:52	clj_newb_2345	so running threads are gc roots
03:52	amalloy	that may or may not be the most useful link, clj_newb_2345, but my point is that this is not a clojure question at all
03:52	clj_newb_2345	but what about terminated thraeds?
03:53	clj_newb_2345	I disagree with you; JVM issues shoudl be as on topic as clojure libraries
03:57	hyPiRion	The thread is considered a root while it is running. Once it stops, it's not considered a root anymore. Does that answer your question?
04:07	clj_newb_2345	http://reference.clojuremongodb.info/monger.core.html#var-get-db
04:07	clj_newb_2345	where is create db?
04:08	ucb	clj_newb_2345: without knowing much, it's possible that get-db actually means get-or-create-db
04:08	amalloy	clj_newb_2345: i don't mean it's off-topic, so much as that you'll get better answers in a java context
04:09	clj_newb_2345	Get database reference by name. EXAMPLES (monger.core/get-db "myapp_production") (monger.core/get-db connection "myapp_production")
04:09	clj_newb_2345	the documentation doesn't mention anythign about that
04:10	clj_newb_2345	ucb: but testing it, you're right :-)
04:10	clj_newb_2345	amalloy: ah, noted, thanks for clarifying :-)
04:12	lgs32a	something is very strang
04:12	lgs32a	i just looked at the source code of the meta reader macro
04:13	lgs32a	for the ^token
04:13	ddellacosta	#postgresql
04:13	lgs32a	and whenever i enter ^:x 'a
04:13	ddellacosta	whoops, sorry!
04:13	lgs32a	i get a symbol without meta-data
04:13	lgs32a	but it should have them
04:13	clj_newb_2345	in what context can (refresh) (fromclojure.tools.namepace) be called -- I'm trying to call it on every ring request ... but am getting into errors
04:14	ddellacosta	clj_newb_2345: I usually use it in a repl session when I've added a lot of random crap to a namespace I'm working in. I wouldn't generally use it to reload after every ring request, why do you think you need to do that? There may be another way to get what you want.
04:15	clj_newb_2345	https://gist.github.com/anonymous/9f8248bbcd4ddb196d13
04:15	clj_newb_2345	well, my current work flow is:
04:15	clj_newb_2345	edit clojure file; go to repl,type in (refresh); click "reload" button on browser
04:15	clj_newb_2345	I'm using websockets, so ring requests are very infrequent
04:15	clj_newb_2345	in fact, only when I hit thre reload button
04:16	clj_newb_2345	(yeah, I mean I'm not doing it on every static file load -- only on new websocket creation
04:16	clj_newb_2345	and I'm getting the error of https://gist.github.com/anonymous/9f8248bbcd4ddb196d13
04:16	ddellacosta	clj_newb_2345: hmm, you shouldn't need to do that--just use ring-wrap-reload: http://ring-clojure.github.io/ring/ring.middleware.reload.html
04:16	ddellacosta	clj_newb_2345: that'll make sure you're picking up changes to namespaces in ring handlers.
04:16	clj_newb_2345	oh shit :-)
04:17	clj_newb_2345	how do I link this with compojure?
04:17	ddellacosta	clj_newb_2345: haha…yeah, don't quote me on this, but I thought c.t.n.r was more for repl-based workflows.
04:17	clj_newb_2345	what's ctnr ?
04:17	clj_newb_2345	clojure tools namespace repl
04:17	clj_newb_2345	ah
04:18	ddellacosta	clj_newb_2345: sorry, abbreviating it: clojure.tools.namespace.reload. yah
04:18	ro_st	clojure.tools.namespace/resfresh
04:18	ddellacosta	er, refresh, sorry
04:18	ddellacosta	what ro_st said.
04:19	lgs32a	so, again
04:20	ddellacosta	lgs32a: sorry, I wasn't quite sure what your issue was.
04:20	lgs32a	well
04:20	ro_st	clj_newb_2345: check out https://github.com/juxt/jig
04:20	lgs32a	,^:test-kw 'x
04:20	clojurebot	x
04:20	lgs32a	,(meta *1)
04:20	clojurebot	nil
04:20	lgs32a	why?
04:20	clojurebot	http://clojure.org/rationale
04:21	ddellacosta	ro_st: that looks awesome!
04:21	lgs32a	i looked at the source-code of the meta-reader and it returns
04:21	lgs32a	((IObj) o).withMeta((IPersistentMap) ometa);
04:22	lgs32a	which should be equal to
04:22	lgs32a	,(.withMeta 'x {:test-kw true})
04:22	clojurebot	x
04:22	lgs32a	,(meta *1)
04:22	clojurebot	nil
04:22	lgs32a	well in my repl there are meta-data
04:22	lgs32a	if using this syntax
04:23	lgs32a	,(meta (.withMeta 'x {:test-kw true}))
04:23	clojurebot	{:test-kw true}
04:23	ro_st	ddellacosta, clj_newb_2345: jig is put together by @malcolmsparks on twitter. i'm sure he'd love any feedback you might have
04:23	lgs32a	,(meta ^:test-kw 'x)
04:23	clojurebot	nil
04:23	lgs32a	so there you have it
04:23	clj_newb_2345	ro_st: will look into it next; thanks :-)
04:23	clj_newb_2345	I am a far is staur sierra's "reloaded" workflow
04:24	clj_newb_2345	had some hacked up solution of my own, but not nearly as formalized / well defined
04:24	ro_st	jig is a progression of SS's reloaded
04:24	ro_st	even if you never use jig, its documentation is a great unpacking of the concepts
04:24	clj_newb_2345	I'm afraid
04:24	clj_newb_2345	i won' get any work done tonight :-)
04:24	clj_newb_2345	if I keep on studying new libraries
04:25	ro_st	there's always another yak to shave
04:25	lgs32a	now i wonder if the ^: tag is ignored if I evaluate a simple form
04:26	ddellacosta	lgs32a: looking into it
04:26	lgs32a	i think i have it
04:26	lgs32a	haha
04:26	hyPiRion	lgs32a: you're attaching the metadata to the list (quote x), not the symbol x
04:26	lgs32a	this is not easy
04:26	lgs32a	exactly i realized it this moment
04:32	clj_newb_2345	(ring.middleware.reload/wrap-reload chat-handler :dirs ["clj"]) <-- is this the right way to use wrap-reload ?
04:32	clj_newb_2345	in particular, for passing the :dirs option
04:34	quazimodo	it's painful that java and jvm are discussed in a lispy place :(
04:34	quazimodo	hard to come to grips with it
04:35	ro_st	clj_newb_2345: yes, but you must include all the paths. so if you have src and clj, you must include both
04:35	clj_newb_2345	I only have clj/*/.clj
04:36	clj_newb_2345	but it's not working :-(
04:37	clgv	clj_newb_2345: do you have problems to set up source paths in project.clj?
04:38	ro_st	you need to restart your webserver after altering that line
04:39	clj_newb_2345	testing
04:39	clj_newb_2345	I had to tell project.clj to look in clj too
04:39	clj_newb_2345	I like clj in clj/ and cljs in cljs/
04:40	clj_newb_2345	fuck this
04:41	clj_newb_2345	i'll just have eamcs tell repl to execute (refresh) on every save
05:23	jave	Is there an existing method for calling lein from maven?
05:33	glosoli	Hey, anyone using enlive ? I have a template which I transform to show form errors in, but then I fix issues and submit form again, which works just fine, i want to go back, and I still see all the errors transformed, any ideas how could I fix this ?
05:34	cgrand	@glosoll: seems like page with errors got cached by the browser, not sêcific to enlive
05:34	ro_st	glosoli: first replicate the behaviour in a repl by banging on the function that does the trans directly
05:35	borkdude	could it be that `lein with-profile test cloverage` is messing my jvm-opts up?
05:36	glosoli	thanks
05:55	zapu	what's the state of clojureclr and vsclojure plugin?
05:57	clj_novice_2345	what are good clojurescript bindings for something mark-down like?
05:57	ddellacosta	is there an official edn mime-type?
05:58	clj_novice_2345	in particular, I want something where where there is a "textural" representation of the page
05:58	ddellacosta	lots of questions all of a sudden, heh
05:58	clj_novice_2345	but it can also be rendered nicely into HTML
05:58	ddellacosta	clj_novice_2345: are you asking for a library that can do markdown/something like markdown?
05:59	clj_novice_2345	i wnat to design a webpage
05:59	clj_novice_2345	where there's a left pane and a right pane, where the user edits text in the left pane
05:59	clj_novice_2345	and it's real time rendered in the right pane
05:59	clj_novice_2345	and I'd like to do this clojurescript
05:59	clj_novice_2345	I'm okay with using javascript libraries
05:59	ro_st	like mouapp.com does
05:59	ro_st	clj_novice_2345: https://github.com/evilstreak/markdown-js
06:00	clj_novice_2345	ro_st: you're ike future me
06:00	clj_novice_2345	in terms of clojure libraries
06:00	ddellacosta	clj_novice_2345: huh, interesting, I did something very similar, only using a top/bottom view
06:00	ro_st	mouapp is an osx app. nothing to do with clj/s :-)
06:01	clj_novice_2345	mouapp.com -- that's a desktop app, not a webpage, no?
06:01	ddellacosta	I used https://github.com/chjj/marked, as it's quite fast, although haven't compared to anything else in a while.
06:02	ro_st	yes
06:04	borkdude	how can I print the jvm-opts that lein cloverage uses
06:05	ddellacosta	so, no answers on edn mime-type? I'll use text/edn for now, but wasn't sure if there was anything official. Having trouble googling for it.
06:06	ro_st	ddellacosta: application/edn
06:07	ddellacosta	ro_st: ah, yeah, just started finding that poking around. Thanks!
06:07	ddellacosta	makes sense since json is application/json.
06:07	ro_st	yes
06:22	H4ns	is there a way to validate an edn file? i have a large edn file that is rejected with "Map literal must contain an even number of forms" by clojure.edn/read, but i don't know where the problem is located in the file.
06:23	ro_st	try a normal read-string with clojure 1.5+ ? it might report the line/column numbers
06:24	ro_st	otherwise load the file into emacs/vim with paredit and use next-form to jump through the file until it shouts at you
06:24	ro_st	tedious to do that though if your data is biggish
06:24	H4ns	right. that's why i'm looking for a better error message. i'll try read-string, thanks.
06:25	H4ns	same message :(
06:25	ro_st	try using tools.reader
06:25	ro_st	http://clojure.github.io/tools.reader/
06:26	ro_st	if you find a way to get line/col reports, please let us know :-)
06:26	H4ns	thanks, i'll try that
06:36	Bronsa	ro_st: H4ns the edn reader does not annotate any line/column info
06:38	ro_st	Bronsa : is there a reader which does?
06:38	H4ns	LineNumberingPushbackReader seems to be, but i'm not sure.
06:42	Bronsa	ro_st: H4ns I meant read-string
06:42	Bronsa	if you use read+clojure.tools.reader.reader-types/indexing-push-back-reader you get line/column info in the ex-data
06:43	ro_st	aha. is there a sample of that somewhere?
06:43	ro_st	this smells like a cookbook recipe
06:43	ro_st	we use edn as a data format and having this info when reporting an error would be tres useful
06:44	Bronsa	ro_st: H4ns user=> (use 'clojure.tools.reader.edn)

06:45	supersym	nice..a creative friend just passed me https://medium.com/about/9e53ca408c48
06:45	supersym	from the dudes that made twitter
06:49	ro_st	Bronsa: you rock star!
06:53	sm0ke	Hello i have (def a (SomeJavaClass.)) ..this class has a public var o which i want to reassign,,, how do i do that?
06:54	ro_st	(set! a (.-var) <new-val>)
06:55	ro_st	-shoots from the hip-
06:57	sm0ke	so i would do (set! a (.-o) <new-val>)
06:57	sm0ke	hmm...weird synta
06:57	clgv	looks like cljs syntax
06:57	ro_st	it is cljs syntax. might be different for java. probably is different
06:58	Bronsa	it's actually (set! (.field instance) val)
06:59	Bronsa	.field or .-field are essentially the same in clojure
06:59	clgv	Bronsa: ah right. that was added sometime after 1.3 right?
07:00	ro_st	thanks for the correction, Bronsa
07:00	glosoli	I have two maps and I would like to compare only the values which rely to the common keywords between those maps, any ideas ?
07:00	clgv	glosoli: keys + set + select-key + =
07:00	ro_st	glosoli: use ((set (keys map1) (set (keys map2))
07:01	ro_st	wait, that's probably wrong, too
07:01	ro_st	,(#{:a :b} #{:a :c})
07:01	clojurebot	nil
07:01	ro_st	,(clojure.set/intersection #{:a :b} irc://irc.freenode.org:6667/#%7B:a :c})
07:01	clojurebot	#<RuntimeException java.lang.RuntimeException: Unmatched delimiter: }>
07:01	ro_st	gah
07:01	clgv	glosoli: determine the common keys by creating a keyset each and itnersect those. then use select-keys with the prev result
07:02	ro_st	,(clojure.set/intersection #{1 2 3} #{2 3 4})
07:02	clojurebot	#<ClassNotFoundException java.lang.ClassNotFoundException: clojure.set>
07:02	ro_st	you get the idea
07:03	glosoli	yeah thank you both
07:05	Bronsa	clgv: it wasn't in 1.3, i don't remember if it was added on 1.4 or 1.5 though
07:07	H4ns	(keyword "hello[123]") => :hello[123] - that's kind of sad :( - is there some syntax for quoted symbols?
07:08	Bronsa	'(keyword "foo bar")
07:08	clgv	H4ns: what do you want to do?
07:08	Bronsa	,(keyword "foo bar")
07:08	clojurebot	:foo bar
07:08	clgv	,'bla
07:08	clojurebot	bla
07:08	clgv	,(type 'bla)
07:08	clojurebot	clojure.lang.Symbol
07:08	Bronsa	H4ns: symbol/keyword don't do any validation for performance reasons
07:09	H4ns	clgv: i have some json data which uses "foo[bla]" as keys. when i turn that data into clojure maps with keywords as keys, i end up with unreadable data
07:09	Bronsa	H4ns: you'll have to make those keys strings
07:10	Bronsa	neither symbols nor keywords can handle that
07:10	Bronsa	clojure doesn't have the #\|symbol with special chars\|# syntax that e.g. common lisp has
07:10	sm0ke	,(rep 1)
07:10	clojurebot	#<CompilerException java.lang.RuntimeException: Unable to resolve symbol: rep in this context, compiling:(NO_SOURCE_PATH:0:0)>
07:11	H4ns	Bronsa: that was what i was after.
07:11	sm0ke	,(repeat 1)
07:11	clojurebot	(1 1 1 1 1 ...)
07:11	sm0ke	,(doall (repeat 1)) ;hahaha
07:11	clojurebot	#<OutOfMemoryError java.lang.OutOfMemoryError: Java heap space>
07:11	H4ns	Bronsa: thanks, i'll find my way through cheshire to see whether i can make it do trt for me.
07:11	Bronsa	(err, just \|symbol with spaces\|)
07:14	clgv	,(println "sm0ke: Bad boy!")
07:14	clojurebot	sm0ke: Bad boy!\n
08:18	Janiczek	Hi, I'm using Enlive to transform RSS file. I see something relevant on github wiki: https://github.com/cgrand/enlive/wiki#resources - but I'm not sure how to specify I want xml-resource in the deftemplate...
08:19	cgrand	just use (xml-resource (java.netURI. "….")) as the source of the deftemplate (e.g. before the args vec)
08:20	Janiczek	tried (xml-resource "filepath"), helped with some problems (<link></link>http://) but stripped the <?xml thing at the beginning. will try the (java.netURI. ...)
08:23	Janiczek	hm, that probably amounts to the same thing. cgrand, would you know what to do with disappearing <?xml version="1.0" encoding="UTF-8" ?> ?
08:25	glosoli	hmm I have set like this, which I got returned by intersection on two sets, hmm I can to seem find if there is some shorthand for retrieving keys out of this? #{[:last-name "somelastname"] [:id "somenumberid"]} I was considering to use (keys (into {} thisset))
08:26	cgrand	@janiczek fill a bug, in the mean time, cons the missing <?xml ….?> on the output of the template call
08:26	Janiczek	cgrand: ok
08:26	Janiczek	thanks :)
08:28	TEttinger	glosoli, get-in ?
08:28	squidz	does anybody have an idea how I can run php in my clojure project(with jetty)?
08:29	TEttinger	hm crud, nvm gleag
08:29	TEttinger	glosoli
08:29	gleag	Have I been summoned?
08:29	glosoli	TEttinger hmm ?
08:30	TEttinger	glosoli, the problem is each element of the set is a vector, so to use get-in you would need to pass... hm are sets even associative
08:30	TEttinger	sorry gleag, typo on name completion
08:31	TEttinger	glosoli, basically you want things like :last-name and not "somelastname" ?
08:31	glosoli	TEttinger: yeah, I have one set of keys and that kind of set full of vectors, and I want to find which keys from the set are in the later set with inside vectors
08:31	TEttinger	if they're all structured like that, ##(map first #{[:last-name "somelastname"] [:id "somenumberid"]})
08:31	lazybot	⇒ (:last-name :id)
08:32	squidz	I want to be able to access php files served by ring? is that possible?
08:33	glosoli	TEttinger: thanks! :)
08:34	TEttinger	glosoli, be advised, if the vectors have multiple keys it won't do what you want
08:34	TEttinger	##(map first #{[:last-name "somelastname" :first-name "Jim"] [:id "somenumberid"]})
08:34	lazybot	⇒ (:last-name :id)
08:35	glosoli	understood
08:35	TEttinger	but I do love how simple these things can be in clojure with the right combinations. it's like a puzzle with well-documented pieces
08:35	Janiczek	cgrand: does this suffice? https://github.com/cgrand/enlive/issues/78
08:36	cgrand	janiczek: perfect
08:37	cgrand	thank you
08:37	Janiczek	ok great :) gonna go cons that thing in. thanks for help!
08:43	AimHere	cons ? This is #clojure, we conj stuff in!
08:45	sm0ke	,(cons 1 [2 3])
08:46	clojurebot	(1 2 3)
08:47	AimHere	,(conj '(2 3) -1 0 1)
08:47	clojurebot	(1 0 -1 2 3)
08:48	AimHere	More flexible and by extension more idiomatic!
08:49	H4ns	is there an equivalent to (rest (butlast x)) (i.e. return the "middle" elements of a list or nil for a two-element list?
08:50	H4ns	surprise! it is (rest (butlast x))
08:50	H4ns	:D
08:50	sm0ke	,(conj '(2 3) 1 0 -1) ; i think you meant
08:50	clojurebot	(-1 0 1 2 3)
08:51	AimHere	Yeah, well that's the thing with conj. You have some cognitive overhead with all the extra arguments and extra collection types!
08:51	sm0ke	:)
08:53	AimHere	H4ns, (butlast (rest x)) gives you an actual nil nil, where (rest (butlast x)) only gives you an empty collection. This might (but probably doesn't) make a difference to you
08:53	AimHere	In the two-items-or-less case anyways
08:54	H4ns	AimHere: right. it does not matter, i was just thinking in common lisp, assuming that it would be different in clojure.
08:54	H4ns	AimHere: thanks anyway :)
09:18	stuartsierra	freiksenet: Re conversation about seqs on Java arrays (August 21) see updated language on http://clojure.org/sequences
09:46	yury	hi everybody
09:47	yury	how to translate list ("a" "b" "c") to hash-map ({:97 "a"} {:98 "b"} {:99 "c"}) ?
09:47	mpenet	,(zipmap [97 98 99] ["a" "b" "c"])
09:47	clojurebot	{99 "c", 98 "b", 97 "a"}
09:48	mpenet	ah well not exactly
09:48	AimHere	,(map hash-map [:97 :98 :99] ["a" "b" "c"])
09:48	clojurebot	({:97 "a"} {:98 "b"} {:99 "c"})
09:48	yury	where 97 98 and 99 is (hash of respective "a" "b" and "c")
09:48	mpenet	or yes, your question is can be misinterpreted, you want a list of hashmaps of a single map?
09:48	yury	single map
09:49	yury	to be able to use (get hash_list some_key)
09:49	mpenet	so yes, my first answer works
09:50	AimHere	Well doesn't quite work - your first argument to zipmap will be created by something like (map hashify ["a" "b" "c"])
09:51	hyPiRion	,(into {} (map (juxt hash identity) ["a" "b" "c"]))
09:51	clojurebot	{97 "a", 98 "b", 99 "c"}
09:52	hyPiRion	If you want that thing as a keyword
09:52	hyPiRion	,(into {} (map (juxt (comp keyword hash) identity) ["a" "b" "c"]))
09:52	clojurebot	{nil "c"}
09:52	mdrogalis	,(map hash ["a" "b" "c"])
09:52	clojurebot	(97 98 99)
09:52	hyPiRion	well, kind of
09:52	mdrogalis	Hm
09:52	hyPiRion	,(into {} (map (juxt (comp keyword str hash) identity) ["a" "b" "c"]))
09:52	clojurebot	{:97 "a", :98 "b", :99 "c"}
09:52	hyPiRion	but may as well do it with pure ints
09:56	mdrogalis	Also not a good idea to have integer keywords.
09:56	mdrogalis	,(keyword 11)
09:56	clojurebot	nil
09:58	AimHere	,(int :11)
09:58	clojurebot	#<ClassCastException java.lang.ClassCastException: clojure.lang.Keyword cannot be cast to java.lang.Character>
10:03	rurumate	G'day folks, I'se got a clojurescript question. When typing script/test, the system responds that neither V8_HOME, SPIDERMONKEY_HOME or JSC_HOME are set; now which of these package is the easiest to install, and where to point the HOME var?
10:04	cmajor7	is there a reason why a depreciated "resultset-seq" is used in "with-query-results*": https://github.com/clojure/java.jdbc/blob/master/src/main/clojure/clojure/java/jdbc.clj#L992 ? #https://github.com/clojure/java.jdbc
10:14	yury	hyPiRion, thanks a lot, (comp keyword str hash) works like a charm
10:16	squidz	has anybody got the source-maps working for clojurescript? My file cljs file structure is correct in the browser, but when I try to open one of the cljs files, they are not found. Anybody try it out yet?
10:16	tbaldridge	squidz: yeah, it's not working for me either yet. I haven't spent the time to figure it out yet. I'm sure it's something with my cljsbuild config
10:17	squidz	i figured it is also something with my project.clj, but haven't been able to figure it out yet
10:19	rurumate	ok found it, https://github.com/clojure/clojurescript/wiki/Running-the-tests
10:21	R_Macy	anyone using cemerick's `friend` library?
10:22	R_Macy	I've included `[ring "1.2.0"]` in my deps, but I'm getting the following exception `Exception in thread "main" java.io.FileNotFoundException: Could not locate ring/util/request__init.class or ring/util/request.clj on classpath` from this file https://github.com/cemerick/friend/blob/master/src/cemerick/friend/workflows.clj#L4
10:22	stuartsierra	Relevance and Metadata Partners (owner of Datomic) have merged to form Cognitect: http://www.cognitect.com/
10:22	hyPiRion	Hmm, interesting changes for Relevance and Rich.. Hopefully for the better of the community.
10:23	hyPiRion	ah, zing
10:23	stuartsierra	heh, perfect timing. :)
10:23	hyPiRion	I would assume it doesn't change anything dramatically though, I feel like you guys have been working close for a very long time already.
10:25	stuartsierra	In the short term, yes, there won't be any dramatic changes.
10:25	seangrove	I wasn't aware that Metadata Partners were the owners of Datomic, somehow I thought it was relevance
10:26	stuartsierra	In the long term, this should mean more and better commercial support for Clojure, ClojureScript, and Datomic,
10:26	seangrove	squidz: You need to have the the source files available to the browser
10:26	seangrove	If you right-click on the source file inside the chrome source viewer and open in a new tab, you can see the path it's using to open
10:27	seangrove	likely you'll need to cp your src/ files and subdirs to resources/public
10:27	stuartsierra	seangrove: The relationship was always close, but Metadata Partners used to be a separate company in which Relevance owned a large stake. Now both Metadata Partners and Relevance are parts of Cognitect.
10:28	squidz	seangrove: it is just pointing the file path on my file system: /home/squidz/programing/clojure/file.cljs
10:29	seangrove	squidz: Yeah, the browser won't be able to open that
10:29	wakeup	How do I check in for EOF?
10:29	wakeup	(in Clojure)+
10:29	hyPiRion	,(read)
10:30	clojurebot	Execution Timed Out
10:30	wakeup	(without modyfing in)
10:30	hyPiRion	&(read)
10:30	lazybot	Execution Timed Out!
10:30	squidz	seangrove: all the files I need are stuffed in the :output-dir specified in project.clj right?
10:30	hyPiRion	I thought one of them had in closed. Seems like I'm wrong on that.
10:30	wakeup	hyPiRion: read will consume input.
10:30	tbaldridge	wakeup: you can't you have to use a pushbackreader, http://docs.oracle.com/javase/7/docs/api/java/io/PushbackReader.html
10:31	tbaldridge	wakeup: at least I don't know of a way
10:31	wakeup	-.-
10:31	wakeup	this is seriously shameful
10:31	tbaldridge	wakeup: that's kindof tied to the OS though, I'm not aware of any OS socket/stream that allows peek.
10:31	hyPiRion	wakeup: Just read from System/in
10:32	seangrove	squidz: I don't think that matters, your cljs files won't get spit out there
10:32	wakeup	tbaldridge: err no, EOF-P is a completely standard function in a programming language
10:33	tbaldridge	wakeup: but not at the OS level. Notice how Unix read simply returns -1 on EOF. http://linux.about.com/od/commands/l/blcmdl2_read.htm
10:33	squidz	seangrove: ah okay, so we still have to manually cp all of our clojurescript files to a directory accesable by the browser?
10:33	tbaldridge	wakeup: also, http://stackoverflow.com/questions/2082743/c-equivalent-to-fstreams-peek
10:33	seangrove	squidz: I believe so, I didn't see any code that indicated otherwsire
10:34	seangrove	But maybe dnolen can confirm how he's doing it in his example
10:34	wakeup	tbaldridge: by the OS level you seem to mean ANSI C, well C has unread...
10:34	squidz	yeah not sure if he is reachable right now. If not maybe i'll ask him later
10:34	tbaldridge	wakeup: yep, and pushbackreader has unread
10:35	wakeup	tbaldridge: which is a java class?
10:35	tbaldridge	wakeup: yes
10:35	tbaldridge	wakeup: it's what Clojure's internal lisp reader uses.
10:35	dnolen	squidz: I changed the REPL web server to resolve the full paths in the source map file. Up for discussion what the best thing for tools is.
10:36	wakeup	tbaldridge: so Clojure does have neither unread nor eof-p
10:36	dnolen	squidz: so you may have to copy the files if you're using a custom webserver, but you could probably do I what I do w/ dev-only middleware or something like that.
10:37	squidz	dnolen: is it in the cljsbuild project?
10:37	tbaldridge	wakeup: nope, the JVM classes are considered sufficient and adding other layers would just add overhead.
10:37	dnolen	squidz: no, all the changes were to the browser REPL server
10:37	dnolen	squidz: it's more or less a hack so that people can try it out and figure out what they need and what they want tools to do.
10:38	squidz	dnolen; where is that at? It is kind of confusing as there seems to be lots of pages out there on different ways to get browser repls up.
10:38	dnolen	squidz: I'm not planning on putting any more thought into, what tools needs will guide what happens next.
10:38	dnolen	squidz: I don't know anything about external browser REPLs
10:39	dnolen	squidz: only the one that ships with ClojureScript. Can be used with `lein trampoline cljsbuild repl-listen`
10:40	dnolen	squidz: http://swannodette.github.io/2013/09/15/source-maps/, you shouldn't need any more information than this to try it out
10:41	squidz	dnolen: I meant projects like piggieback, austin, and other documenation from modern clojurescript. I couldn't seem to get lein trampoline cljsbuild repl-listen working. After going to the address, it says it can't find index.html
10:41	dnolen	squidz: I don't know anything about that stuff.
10:42	dnolen	squidz: I say in the post you need to make an index.html and include your output js file.
10:42	seangrove	dnolen: I've never used the built-in browser repl. I like how your trick about resolving source code, wonder if we can work with cemerick to get something similar in piggieback and friends
10:43	dnolen	seangrove: probably! I look forward to hearing feedback from these tools about what they need to integrate source map functionality best.
10:44	squidz	dnolen: okay, but from where is the server looking for resources? I'm guessing this is separate from ring/compojure configuration in a project
10:45	dnolen	squidz: it's a hack best understood by looking at the source http://github.com/clojure/clojurescript/blob/master/src/clj/cljs/repl/browser.clj#L74
10:45	dnolen	squidz: like I said I can't give any guidance on how to make it work with your setup
10:45	squidz	okay thanks, I think that is the last piece missing to get it going
10:47	squidz	ive never used the built in browser repl from lein
10:48	squidz	so I see I just put the index.html at the root of my clojurescript project. Thanks
10:52	squidz	dnolen: seangrove yeah, after getting the built-in browser repl going, the source-maps work
10:53	arkh	how would one assign a method to a javascript object instance via clojurescript?
10:53	arkh	I'm trying to override the default behavior of goog.fx.Dragger
10:53	ro_st	you can't register an event handler for it?
10:53	xeqi	stuartsierra: is lein considered part of the clojure platform with regards to support?
10:54	stuartsierra	xeqi: No, Leiningen is maintained by Phil Hagelberg and volunteers.
10:54	arkh	ro_st: I'm trying to assign a function to defaultAction
10:55	ro_st	(set! (.-defaultAction thing) #(println "does this work?"))
10:55	ro_st	how about that?
10:56	arkh	ro_st: ohhh
10:56	arkh	ro_st: that's probably what I need - sorry for the silly question : /
10:56	ro_st	(aset thing "defaultAction" #(println "woo"))
10:56	ro_st	that'll probably do it
10:57	arkh	ro_st: I'll check those out - thank you
10:57	rurumate	ok, I installed v8 according to clojuresript "Runnning the tests" wiki. Now script/test says "Error: Could not find or load main class clojure.main"
10:58	ro_st	arkh: the only silly question is the one you don't ask :-)
10:59	rurumate	has anyone had this problem when running clojurescript's script/test ?
10:59	AimHere	ro_st, I'm just glad he didn't ask it!
10:59	tbaldridge	gfredericks: atom will be much faster, it's basically the cost of locking a CPU cache line
11:00	tbaldridge	gfredericks: for even more performance you can always drop to Java's AtomicReference
11:02	stuartsierra	or AtomicLong if you're only storing an integer.
11:02	tbaldridge	(inc stuartsierra)
11:02	lazybot	⇒ 4
11:02	tbaldridge	wow, so low? Let's do that a few times more
11:02	tbaldridge	(inc stuartsierra)
11:02	lazybot	⇒ 5
11:02	stuartsierra	heh.
11:03	dnolen	rurumate: did you run the boostrap script?
11:03	rurumate	dnolen: no
11:04	dnolen	rurumate: you need to do that first
11:04	dnolen	squidz: cool
11:05	gfredericks	tbaldridge: I thought that might be the case; my naive gut though was to go with agent due to not having to contend
11:05	tbaldridge	gfredericks: the sad thing is, you still have to contend for the agent's queue. So agents use AtomicReferences.
11:05	gfredericks	tbaldridge: yeah that was my less naive fear
11:06	gfredericks	eventually I concluded I should just measure the dang things :)
11:06	gfredericks	5 microseconds for the agent, 200 nanoseconds for the atom
11:06	tbaldridge	nah, I prefer to measure last. Always assume, it's more exciting when you do benchmark that way. :-P
11:07	Kalimar	Good morning
11:07	mmoriarity	Good morning!
11:09	hhenkel	Hi all, what is the best way to do simulate nested for loops in clojure? I used postwalk before, but how would I recognize if I'm in an explicit subtree?
11:11	opqdonut	nested for loops? why not just:
11:11	opqdonut	,(for [a [[1 2 3] [4 5]] b a] {:value b})
11:11	clojurebot	({:value 1} {:value 2} {:value 3} {:value 4} {:value 5})
11:11	opqdonut	or did you mean something else?
11:13	hhenkel	opqdonut: I got a tree structure containing multiple levels. I want to walk a part of it and substitute some values if I'm underneath a certain tree.
11:14	hhenkel	Something like, if I find ":type" and I walked, domain, and servers before I want to substitude it.
11:14	opqdonut	I'd start by writing out the straightforward recursive implementation
11:15	opqdonut	but maybe that's just me
11:16	jstew	Same here. When I see the word tree, my brain automatically says "recursion".
11:19	hhenkel	opqdonut: jstew: That's the same with me, but I'm currently not able to develop that in clojure as this it to new to me...
11:20	hhenkel	I guess I should loop and recur for that, right?
11:20	ro_st	hhenkel you might find that clojure.zip is more suited to what you're after
11:20	gleag	That's not just you, it's the same thing that makes people who see a crystal immediately think "symmetry groups".
11:20	gleag	Generally, it's called "factual relevance" :)
11:21	jstew	hhenkel: Yes, loop/recur is best if your tree size is not very small, or if it's of an unknown length.
11:21	AimHere	hhenkel, that's one way. Often a recursive function with a 'reduce' in it is a good fit too, depending on what exactly you're up to
11:23	jstew	clojure.zip looks very nice as well. I didn't know about it until just now. Thanks, ro_st.
11:24	hhenkel	ro_st: jstew: AimHere: okay, thanks for your input. I'll check if I get a step forward.w
11:25	ro_st	happy hunting :-)
11:28	ddellacosta	hhenkel: yeah, I was going to say what jstew said, check out clojure.zip and Huet's zipper data structure (http://en.wikipedia.org/wiki/Zipper_(data_structure))
11:28	ddellacosta	oh, and what ro_st said too...haha
11:31	TimMc	Hmm, how come I see all these #<Var: --unnamed--> in (get-thread-bindings)?
11:34	TimMc	,(remove #(.ns (key %)) (get-thread-bindings))
11:34	clojurebot	([#<Var: --unnamed--> #<DynamicClassLoader clojure.lang.DynamicClassLoader@12be529>] [#<Var: --unnamed--> 0] [#<Var: --unnamed--> 0])
11:35	TimMc	,(map (comp meta key) (remove #(.ns (key %)) (get-thread-bindings)))
11:35	clojurebot	({:ns nil, :name nil} {:ns nil, :name nil} {:ns nil, :name nil})
11:38	kanja	I'm looking at building a webapp in clojure as a first project - does anyone have an opinion on compojure or pedestal?
11:38	ro_st	start with ring and compojure and enlive or hiccup
11:38	rkneufeld	kanja: For simple web apps Compojure or luminous is probably your best bet (saying this as one of the team members on pedestal)
11:39	ro_st	pedestal is aimed at 'in the large' apps
11:39	kanja	ah ok
11:39	kanja	so start with compojure to skill up and then make an informed decision to use pedestal
11:39	jstew	kanja: I like compojure. It's simple. Pedestal seems like a really huge learning curve. Might pay off for a very large system.
11:39	endou	the client side of Pedestal look really interesting, I loved the documentation it's really sensible
11:40	rkneufeld	yeah, it is important to consider pedestal-app and pedestal-service separately
11:40	ro_st	kanja: you could start with pedestal services and ignore pedestal app for now, especially if you want to muck around with stuff like HTTP SSE
11:41	kanja	ro_st: that would probably get me up to speed quicker
11:43	kanja	enlive and hiccup are both for html templating?
11:43	TimMc	nDuff: Here's a pastebin you might like: http://code.solusipse.net/
11:44	ro_st	kanja they have different approaches
11:44	nDuff	TimMc: Hmm. I'm already pretty happy with sprunge.us and ix.io in the "easy to feed to from CLI" category.
11:44	ro_st	hiccup turns clojure data into html. enlive transforms html files from disk
11:45	kanja	ro_st: That is an excellent way to explain it, thank you. It sounds like enlive might be better for me to look into as it fits the style I'm used to working in
11:45	ro_st	cool :-) enlive also supports simple bits of hiccup in its transforms, so using both is perfectly an option
11:46	kanja	oh sweet
11:46	ro_st	perfectly acceptable as an option*
11:47	jstew	I am really digging angular-js on the frontend, and using ring/compojure for JSON. It's making web dev fun again for me.
11:55	tangrammer	Hi folks! Does anyone know where to find a clojure tele-work/telecommute job?
11:57	mgaare_	tangrammer: hook up with a recruiter that specializes in jvm languages and then wait :D
11:58	nDuff	tangrammer: ...having a corpus of publicly-visible work isn't a bad place to start either.
11:59	mgaare_	what's the preferred solution for handling situations where you're using ->, but there's one form where you need to move the argument to the end in just one of the forms?
11:59	tangrammer	mgaare_: thanks! but... any clues to find that recruiter?
11:59	mdrogalis	mgaare_: Maybe not thread then.
12:00	tangrammer	nDuff: thanks nDuff, but can you help me a little more? I don't know how scape from js
12:01	mgaare_	tangrammer: depends on your location
12:01	tangrammer	mgaare_: I live in spain
12:02	tangrammer	mgaare_: but currently i'm working for a NY company
12:02	tangrammer	mgaare_: telecommute js developer
12:04	nDuff	tangrammer: ...well, find some OSS projects you can contribute to on your own time; if you can find an open niche to fill, all the better. Since you're working with JS now, CLJS might be a good place to focus.
12:04	pbostrom	mgaare_: it's kinda ugly but you can wrap the form in a 1-arg anonymous function
12:05	nDuff	tangrammer: ...maintain a well-known library, and that's a very big foot in the door anywhere that uses it.
12:07	mgaare_	tangrammer: some of your coworkers might know of recuirters in the area
12:08	mgaare_	pbostrom: yeah, was hoping someone had a prettier solution :D
12:09	tangrammer	mgaare_: good advise! thanks you are very kind!
12:09	tangrammer	nDuff: good advise! thanks you are very kind!
12:17	jstew	IMO, clojure is a wide open frontier. Lots of things in other languages exist that have no clojure equivalent yet.
12:18	endou	and the other way around too
12:18	hyPiRion	yeah. core.logic is one example
12:21	gfredericks	how does one run a single test from nrepl.el?
12:21	gfredericks	ditto for a single namespace
12:21	borkdude	gfredericks call the test like a function?
12:23	jstew	gfredericks: in nrepl.el C-M-n will switch to the current namespace, then you just call whatever function you want.
12:25	borkdude	C-M-n doesn't work in my setup, I use C-c M-n
12:26	borkdude	I don't understand why I need to do an nrepl-eval-buffer before I can use any of the functions of the namespace I switch to though
12:26	cmajor7	stuartsierra: will Congnitect be a "Typesafe" for Clojure?
12:26	borkdude	gfredericks (run-tests) will then just run the tests from the current namespace
12:27	tbaldridge	cmajor7: how would you define "be a Typesafe"?
12:27	borkdude	gfredericks or you can run one test by just calling it like a function
12:27	leifw	tbaldridge: I think the question is "does 'scala : typesafe :: clojure : cognitect' hold"
12:28	cmajor7	tbaldridge: scala roof
12:28	tbaldridge	leifw: if you define that as "offers commercial support" then yes: http://www.cognitect.com/support#clojure-support
12:29	borkdude	maybe some companies are willing to use clojure if they know there is support and commercial backup for it
12:29	borkdude	some = more
12:29	tbaldridge	(inc borkdude)
12:29	lazybot	⇒ 1
12:30	gfredericks	borkdude: I need the fixtures to run
12:30	cmajor7	tbaldridge: well, more of a "who owns it, who can "they" trust their dollars, is that thing (Clojure/Script/Tomic) for real, going to be marketed as a Clojure homeland, etc…"
12:31	borkdude	gfredericks I haven't used those yet, did most things manually with the test-ns-hook
12:32	gfredericks	borkdude: the (run-tests) call looks good though; wasn't aware of that
12:32	gfredericks	borkdude: thx
12:32	borkdude	gfredericks I guess I need to read up on those :)
12:32	borkdude	gfredericks you can also pass it a namespace symbol to run a different namespace
12:32	borkdude	gfredericks lein test :only … also accepts a namespace
12:33	stuartsierra	cmajor7: I don't think we know the answer to that yet.
12:33	gfredericks	borkdude: yeah, I knew how to do it from the command line; I'm exploring the low-latency options
12:34	borkdude	type and safe are both a bit boring words, cognitect will may be more exciting than just type safety ;)
12:34	technomancy	gfredericks: grench!
12:34	cmajor7	stuartsierra: makes sense. in any case, good to centralize the forces and answering the question "where does Rich work" :)
12:34	technomancy	gfredericks: with such gusto tho
12:35	gfredericks	$google clojure grench
12:35	lazybot	[Raw clojure.main repl hangs · Issue #6 · technomancy/grenchman ...] https://github.com/technomancy/grenchman/issues/6
12:35	technomancy	oh nice; link straight to a closed bug as the first hit lazybot
12:35	hyPiRion	why not
12:35	gfredericks	technomancy: I googled it privately first and assumed that link was irrelevant and was just trying to publically demonstrate that
12:36	gfredericks	technomancy: this is your old idea of a CLI nrepl client to a persistent leiningen process?
12:36	technomancy	it is
12:36	mgaare	gfredericks: you can also use clojure-test-mode, go to the buffer with the tests and C-c M-, on the test you want
12:36	gfredericks	this would still mean launching a project jvm every time
12:36	gfredericks	I'm trying to satiate the TDD masses here
12:36	technomancy	gfredericks: not necessarily
12:36	gfredericks	also "learn a whole new build tool" is a bit prohibitive
12:37	technomancy	it should be a drop-in replacement, like drip
12:37	technomancy	and you can keep your project JVM warm
12:37	technomancy	that said it's really new and only has a handful of people using it regularly
12:38	technomancy	also it's named after a metafictional nazi skinhead high-school band; not sure if that matters to you personally
12:38	hyPiRion	Only the bleeding edge pros
12:39	gfredericks	metafictional means doubly fictional?
12:39	technomancy	gfredericks: in this case yes. it might have other connotations elsewhere.
12:39	mtp	metafictional means 'fiction about fiction'
12:39	hyPiRion	fiction in fiction at least
12:46	rurumate	dnolen: Ok, script/bootstrap helped with that. Now script/test produces a compile error "Invalid token: ::other/foo"; see http://pastebin.com/X8VL00fp Any ideas?
12:47	danielszmulewi-1	technomancy: how does grenchman fit with working in emacs (nrepl)?
12:48	danielszmulewi-1	technomancy: if at all
12:48	technomancy	danielszmulewi-1: they're pretty much orthogonal
12:48	technomancy	grenchman is basically (among other things) a reimplementation of reply
12:48	dnolen	rurumate: looks like there still something wrong w/ your setup. It's using Clojure's reader instead of tools.reader
12:48	technomancy	which nrepl.el is also a replacement for
12:49	danielszmulewi-1	technomancy: can you launch a nrepl connected with grenchman, or am I out of line?
12:50	danielszmulewi-1	technomancy: I know I might be missing the point
12:50	technomancy	danielszmulewi-1: right now you manage the nrepl processes out of band; that's currently outside the scope of grenchman
12:50	technomancy	because it's difficult to create a flow that manages process state implicitly without hiding too much (see cake)
12:51	danielszmulewi-1	technomancy: so you issue commands from the cli with grenchman?
12:51	technomancy	right
12:51	rurumate	dnolen: all I did was clone, then script/bootstrap && script/test
12:51	technomancy	you start a lein server, then you can s/lein/grench/ for all commands
12:52	dnolen	rurumate: sorry can't help you trouble shoot atm, perhaps someone else can.
12:52	danielszmulewi-1	technomancy: OK, I should try it out. Most of the time, I'm busy in my project, concerned with reloading code or reevaluating functions. Not much a use case here, iight?
12:52	danielszmulewi-1	right?
12:52	technomancy	danielszmulewi-1: no, you can also keep a project JVM hot for an even greater boost
12:53	danielszmulewi-1	technomancy: oh, so there is a use case. Definitely I should look into it.
12:53	technomancy	so if you want to run a lein task (like doing a test across multiple namespaces, which nrepl.el doesn't attempt) you could do it quickly with grench
12:53	danielszmulewi-1	technomancy: yes, true that.
12:54	technomancy	but for quick "does this change I made still work with this function call I'm running in the repl" it doesn't make sense for emacs users
12:55	danielszmulewi-1	technomancy: OK, cool. Sounds intriguing. At least I already installed OCaml. :-)
12:55	technomancy	nice
12:56	eric_normand	has core.async been updated to work with the new keywords in clojurescript?
12:56	tbaldridge	eric_normand: yes, but the latest release has not been cut yet from what I know. So I'm currently using the latest ClojureScript with 0.1.0-SNAPSHOT
12:56	eric_normand	tbaldridge: thanks!
13:00	jstew	Slightly OT: What color theme are you emacs users using? Zenburn is starting to zenburn my eyeballs.
13:01	technomancy	jstew: monokai is a nice change of pace
13:01	technomancy	it's not as mellow as zenburn though
13:01	xeqi	monokai here
13:01	mbarbieri	Hi, advice please: I have a pretty big data structure (a map of maps of vectors of maps) with fixed keys and values, don't need to change them, no need of Java interoperability. At the beginning I had all keys-values hand written, now I'm starting using function to generate pieces of this structure and avoid repetition, would it be better to use records?
13:02	jstew	monokai. I'll try that one. Thanks.
13:03	Raynes	jstew: I'm a fan of base16
13:03	Raynes	https://github.com/chriskempson/base16
13:04	jstew	Pretty.
13:04	jkkramer	mbarbieri: maps are probably fine. prismatic's schema might help you document and validate the shape of your data - https://github.com/Prismatic/schema
13:04	eric_normand	anybody going to be at Strange Loop this week?
13:05	technomancy	eric_normand: yesss
13:06	mbarbieri	jkkramer: thanks, will look at that
13:06	Raynes	No, eric_normand, not a single person is going to strangeloop.
13:06	eric_normand	Raynes: well, it was worth a shot :)
13:06	eric_normand	Raynes: I thought it might interest people in this chatroom
13:08	callen	JStoker: I use a custom one. github.com/bitemyapp/dotfiles/
13:09	eric_normand	technomancy: looking forward to any sessions in particular?
13:10	callen	mbarbieri: definitely just use maps.
13:10	mdrogalis	eric_normand: Couldn't get there this year, hopefully next.
13:10	mdrogalis	The talk list looks awesome.
13:10	eric_normand	I agree
13:10	eric_normand	mdrogalis: just trying to narrow it down
13:11	muhoo	heh, t-mobile templating fail: $ {{plan.price}} per month
13:12	muhoo	someone's using moustache.
13:12	callen	mustache*
13:12	muhoo	(or some javascript thing on the client side, i have noscript)
13:12	callen	wonder how the template flew past unrendered.
13:13	callen	muhoo: mustache is a client-side lib too. Could be handlebars.
13:13	mdrogalis	Closing song from Cognitect's podcast is excellent.
13:14	bja	could be django/jinja2 too
13:14	bja	and something escaped from the backend
13:14	bja	{{ }} is pretty common
13:16	callen	bja: I don't think it was Django/Jinja, that's not how the templates render.
13:16	callen	you can't have a raw template slip past like that unless you're doing something wrong.
13:16	callen	more likely it was mustache/handlebars/some derivative of Jinja, and it's probably a frontend template.
13:20	muhoo	huh, i didn't know pedestal was a relevance thing
13:22	supersym	yup... btw, anyone done some device detection in ring yet?
13:23	callen	supersym: that doesn't really compute. Device detection?
13:23	callen	Ring is just an HTTP abstraction.
13:23	supersym	well... server-side user-agent I guess
13:23	supersym	yeah.. well what I wanted to know if there is anything more to it then just fetching that out of the header
13:23	callen	you shouldn't really do things with the user-agent server-side or frontend.
13:24	supersym	I guess my formulation was off, callen... :)
13:24	callen	you just fetch it out of the headers.
13:24	darrickw	Just tried adding :source-map to a small clojurescript project I'm working on, formerly complied fine but now I get an NPE.
13:24	supersym	see I see all these folks on the web talking about server side device API and db etc... I don't get what they are talking about
13:24	supersym	the 'why' since I thought there wouldn't be much more to it then, indeed, like you just said
13:26	darrickw	My deps are core.async, core.match, and crate. Are any of those incompatible with the latest CS snapshot?
13:26	muhoo	supersym: the trendy thing now is responsive design with css on the client side instead of trying to guess on the server side based on user-agent
13:26	mdrogalis	darrickw: Almost definitely not.
13:27	supersym	muhoo: well.... yes and no :)
13:27	dnolen	darrickw: source map functionality is not heavily tested, assume things will not work at all with incremental compilation
13:27	supersym	trendy thing: yes, thats true
13:27	dnolen	darrickw: you need to always lein cljsbuild clean as far I can tell currently (patches / detailed bug reports welcome of course)
13:28	darrickw	Thanks dnolen, that was all it took
13:30	supersym	muhoo: I was thinking more in the line of something I see is now called RESS, btw Twitter also changed back to server-side rendering
13:31	callen	supersym: that doesn't change what muhoo said, he's correct that you should just design your CSS responsively and not change content based on user-agents. Ever.
13:31	callen	changing content based on user-agents is some 1998 bullshit man. I thought people learned their lesson there.
13:31	supersym	oh ok... I didn't say I wanted to do that right
13:32	supersym	haha
13:32	tupi	hello, a license related quiz: can I attach a GPL v3+ to my clojure source code?
13:32	muhoo	callen: i didn't say it so dogmatically or emphatically though :-)
13:32	AimHere	tupi > You can attach it to your own code
13:32	tupi	AimHere: ok, thanks
13:32	AimHere	The source code of clojure proper is available under the EPL
13:32	muhoo	i just said it's trendy. whether it's good or not, i'm fine with letting others decide based on their needs.
13:32	tupi	that is what I wantd to know
13:32	technomancy	tupi: some people claim it's OK if clojure itself is your only EPL'd dependency
13:33	technomancy	tupi: but it would be difficult to write a clojure program and not pull in other EPL'd code
13:33	supersym	muhoo: I know ;) thanks for your input
13:35	muhoo	and, speaking of t-mobile, and user-agent checking, they inspect and proxy traffic on port 80 and block it based on user-agent. if you have chrome on linux, you're golden. use firefox, and you get blocked. use anything on windows, and you get blocked. any ssh or imap or other protocols sail through.
13:35	callen	muhoo: there are subjects that merit wriggle-room. That ain't one of them.
13:35	callen	muhoo: o_O
13:36	callen	you mean tethering?
13:36	tupi	technomancy: i need to check with imagej 'people/license', but right now i am not pulling any other code then imagej
13:36	muhoo	i guess that's to stop people tethering, yeah.
13:36	muhoo	it's along the lines of using rot13 as an encryption algorithm
13:36	callen	aha! Relevance and the Datomic people merged
13:36	supersym	hehe
13:36	technomancy	muhoo: https://addons.mozilla.org/en-US/firefox/addon/firesomething/
13:36	callen	there's going to be one uber-company in Clojure X_X
13:37	muhoo	technomancy: fun, thanks.
13:38	muhoo	technomancy: and since you're here.... what is the magick lein invocation to inject a form to execute when doing repl :conect ?
13:38	muhoo	i.e. i want to connect to a repl, change to a ns, and execute some code, before i get a repl prompt.
13:38	callen	http://exercism.io/
13:39	technomancy	muhoo: I guess :repl-options :init
13:39	borkdude	H4ns you can include a directory like test-resources explicity using the :resources option in leiningen (reacting to something you said 12 hours ago or so)
13:39	muhoo	technomancy: bare on the comand line? or as update-in [:repl-options :init] ?
13:40	borkdude	is there a service that allows you to view the parts from an irc channel you missed, and I don't mean leave your machine on all night or look up log files… something more smoothly, a bit like hipchat maybe?
13:40	technomancy	muhoo: oh, huh. probably put it in a profile and do `lein with-profile +repl-init repl :connect ...`
13:40	muhoo	i was trying to do it without having to create a profile just for that
13:41	technomancy	unless you need to specify it as a cli arg; then update-in would be needed
13:41	muhoo	right, on the cli would be most convenient.
13:41	technomancy	probably an update-in alias
13:41	TimMc	callen: I'm just surprised to learn Datomic had any pretension of being separate from Relevance...
13:41	callen	TimMc: I figured it was going to happen eventually.
13:41	callen	So, I gave paredit and ac-nrepl the old college try again. I'm faster without both of them.
13:42	callen	I've been editing parens in Emacs too long to find paredit helpful - interferes more than anything.
13:42	borkdude	callen paredit crashed my emacs when I pasted a big datomic schema file
13:42	borkdude	it was reproducible
13:43	darrickw	dnolen: apologies, actually that didn't fix it -- I had the source map option commented when I tried earlier. Still getting the same NPE
13:43	borkdude	able
13:43	callen	borkdude: lol
13:43	callen	borkdude: ac-nrepl made my REPL sessions really slow too.
13:43	AimHere	I find paredit the same way. I'm so used to editing s-expressions in my own order that I have to do all sorts of jiggery-pokery to make the closing parens in the right place
13:44	borkdude	I use paredit, but sometimes I turn it off when I am in an invalid state due to copy pasting ;)
13:45	technomancy	merge conflicts are an easy way to make it mad at you
13:45	borkdude	technomancy oh yes, happened to me today
13:48	H4ns	borkdude: thanks! that was suggested to me earlier and it works very well
13:49	borkdude	TIL you should never use the Github app and press sync
13:49	callen	borkdude: definitely not.
13:49	callen	Git was not made for muggle-mode.
13:49	TimMc	What does sync do?
13:50	borkdude	TimMc I think push and pull but I don't know in what order
13:50	callen	but against which remotes and branches? nobody knows!
13:50	callen	:P
13:50	technomancy	callen: GitHub is a lot less hostile than git, in general
13:51	technomancy	but one button for push+pull sounds like an awful idea
13:51	borkdude	I rebased my branch onto a master branch
13:51	borkdude	and then pressed sync and weird shit happened
13:52	callen	technomancy: I like some parts of github, but the desktop app + sync thing is really bad.
13:53	technomancy	speaking of github and bad ideas, does anyone have a user stylesheet to disable their stupid language breakdown bar?
13:53	borkdude	I like the visual overview of the current changes it gives, but probably I shouldn't use anything other than the shell to do stuff
13:55	darrickw	dnolen: FYI, solved my clojurescript source-map issue. The problem was that I had :optimizations :whitespace. In :advanced mode, it builds fine.
14:05	borkdude	is cognitect also going to deliver support for clojureclr? ;)
14:11	eric_normand	dnolen: got source maps working. looks good.
14:11	callen	I can't get consumer tag based consumer cancellation working with Langohr "Unknown consumerTag" - anybody else encounter this?
14:12	eric_normand	dnolen: one problem is that it puts the whole path of the output file in the file, even though they are in the dir
14:12	eric_normand	dnolen: I'm thinking about how I would patch it
14:20	eric_normand	After warming up, new cljs compiler takes 6.5s to compile with advanced optimizations
14:27	dnolen	darrickw: it should work w/ whitespace optimizations too
14:27	dnolen	darrickw: I tried it myself yesterday and it seemed to work - there may be other issues at play
14:28	dnolen	darrickw: if you can construct a minimal case please open a ticket with details
14:29	dnolen	eric_normand: thoughts welcome, I don't have any great ideas there.
14:33	mdrogalis	12:25 http://www.infoq.com/presentations/Design-Composition-Performance Is he talking about tools like Cucumber and FitNesse?
14:33	mdrogalis	I could have sworn I heard him say in another talk that he didn't like testing frameworks like that.
14:34	eric_normand	dnolen: getting weird behavior from PersistentArrayMap
14:35	dnolen	eric_normand: I assume this unrelated to source maps?
14:35	eric_normand	yes
14:35	eric_normand	turned off source maps
14:35	eric_normand	and optimizations
14:35	eric_normand	dnolen: that is, default optimizations
14:36	dnolen	eric_normand: you mean :optimizations :none?
14:36	eric_normand	dnolen: no, no key in the cljsbuild map
14:36	eric_normand	dnolen: let me try with :optimizations :none
14:38	eric_normand	dnolen: ha! doesn't work at all. forgot about that.
14:38	eric_normand	dnolen: Need to include all of goof.*
14:38	eric_normand	goog.*
14:38	eric_normand	sorry, automcomplete!
14:40	bja	dnolen: have you encountered any issues with Closure Compiler's CommandLineRunner.getDefaultExterns() not finding the externs.zip?
14:40	eric_normand	dnolen: ok, it's working.
14:40	eric_normand	dnolen: I just had to delete all the prior output
14:41	eric_normand	dnolen: and recompile
14:41	dnolen	bja: nope
14:41	dnolen	eric_normand: k, this happens if you upgrade ClojureScript and don't clean
14:41	bja	I found a way through cljs's compiler that takes an alternate path (specifying the compiler option :use-only-custom-externs), but I was hoping this is a known issue and just not something with my setup
14:42	eric_normand	dnolen: yeah, that's what happened
14:42	eric_normand	dnolen: sorry to bother you
14:44	callen	technomancy: I was thinking the same thing.
14:49	dnolen	bja: I'm not aware of it, feel free to open a ticket with an explanation if you think it's a problem, higher likelihood of resolution if you attach a patch ;)
14:49	jweiss	.printStackTrace can take a printwriter or outputstream arg, isn't there some straightforward clojure way to get the string representation?
14:49	jweiss	i looked at clojure.java.io but didn't see an obvious way
14:49	bja	jweiss: have you checked out how pp does it?
14:50	bja	err, pst
14:50	jweiss	bja: i know how to manually create a stringwriter, printwriter, etc
14:52	jweiss	bja: it does everything itself :)
14:52	jweiss	i just want to do .printStackTrace but have the result go to a string instead of stdout. i don't want to use with-out-str (i am not sure if other threads writing to stdout would get mixed in there)
14:53	coventry`	jweiss: with-out-str uses the binding macro on out. I think that's thread-local.
14:54	jweiss	coventry`: wouldn't other threads writing to stdout also end up being written there?
14:56	coventry`	jweiss: I'm basing this on "The dynamic var system, exposed through def, binding, et al, supports isolating changing state within threads." <http://clojure.org/concurrent_programming>. Should be easy enough to test.
14:57	jweiss	coventry`: my point is that the jvm's stdout knows nothing about clojure var system
14:57	jweiss	it's just a stream
14:57	eric_normand	jweiss: you are right
14:58	eric_normand	jweiss: out is for clojure functions
14:58	coventry`	Oh, I see.
14:58	eric_normand	jweiss: the standard way to do it is to create a printwriter
14:59	eric_normand	jweiss: then slurp it in as a string
14:59	jweiss	yeah, i figured something in clojure.java.io would do that for me
14:59	jweiss	but i'm not seeing it
15:00	eric_normand	jweiss: or maybe try clojure.repl/pst
15:00	eric_normand	jweiss: it may print to out
15:00	eric_normand	jweiss: I'm not sure
15:01	jweiss	right, same issue there and it uses its own format anyway
15:01	eric_normand	jweiss: I see

15:02	jweiss	,(let [e (doto (Exception. "Fooey") (.fillInStackTrace)) sw (java.io.StringWriter.)] (.printStackTrace e (java.io.PrintWriter. sw)) (.toString sw))
15:02	clojurebot	#<SecurityException java.lang.SecurityException: denied>
15:02	jweiss	bah
15:08	eric_normand	jweiss: looks like it works though
15:12	eric_normand	(defn st-str [e] (with-open [sw (java.io.StringWriter.) pw (java.io.PrintWriter. sw)] (.printStackTrace e pw) (.toString sw)))
15:12	eric_normand	,(defn st-str [e] (with-open [sw (java.io.StringWriter.) pw (java.io.PrintWriter. sw)] (.printStackTrace e pw) (.toString sw)))
15:12	clojurebot	#<Exception java.lang.Exception: SANBOX DENIED>
15:15	eric_normand	,(let [st-str (fn [e] (with-open [sw (java.io.StringWriter.) pw (java.io.PrintWriter. sw)] (.printStackTrace e pw) (str sw)))] (try (/ 0 0) (catch Exception e (st-str e))))
15:15	clojurebot	eric_normand: excusez-moi
15:15	eric_normand	,(let [st-str (fn [e] (with-open [sw (java.io.StringWriter.) pw (java.io.PrintWriter. sw)] (.printStackTrace e pw) (str sw)))] (try (/ 0 0) (catch Exception e (st-str e))))
15:15	clojurebot	eric_normand: It's greek to me.
15:15	eric_normand	come on!
15:15	eric_normand	jweiss: anyway, that works on my machine
16:33	eric_normand	dnolen: how does one test the cljs compiler?
16:34	dnolen	eric_normand: there's no good way to test the compiler currently.
16:38	eric_normand	dnolen: ok, I'll figure it out
16:38	dnolen	eric_normand: what's the problem?
16:38	eric_normand	dnolen: writing a patch for the source map relativizing files
16:39	eric_normand	dnolen: just wanted to make sure I didn't break anything
16:39	dnolen	eric_normand: nice, what about JARs and files served http:// (I don't remember if these get cached locally) ?
16:40	darrickw	dnolen: I just got a chance to try to put together a minimal case for my :whitespace problem. It fails in even the very simplest case, so there's not much to report. (:advanced still works fine)
16:40	dnolen	darrickw: yes but I got it to work just fine :)
16:40	eric_normand	dnolen: I am not sure how those work
16:40	dnolen	darrickw: so a minimal project and the minimal steps still needed.
16:40	dnolen	eric_normand: patch will need to address those cases.
16:41	darrickw	I even used the defproject from your blogpost… ok. I'll put up a gist of the whole project for you :)
16:41	dnolen	eric_normand: otherwise I'm unlikely to look at it.
16:41	eric_normand	dnolen: ok, I'll have to come up with a test case
16:41	dnolen	darrickw: with the precise steps on the command line to recreate error, thanks!
16:41	darrickw	ok
16:42	eric_normand	dnolen: but this does generate a relative path to the source map
16:42	appendonly	i want to understand clojure's implementation better, specifically where the boundary between host (jvm/clr/v8) and runtimes lies. is reading 'clojure in small pieces' the best way to approach this?
16:43	dnolen	eric_normand: maybe I'm missed something, is the "files" v3 source map entry relativized? or are you working on something else?
16:45	eric_normand	dnolen: the URL in this string is a relativized path: //@ sourceMappingURL=cs2.js.map
16:45	eric_normand	dnolen: it was //@ sourceMappingURL=extension/cs2.js.map
16:45	eric_normand	dnolen: but in the file extension/cs2.js
16:45	dnolen	eric_normand: k sorry I was confused :) what is the relativization based on?
16:46	eric_normand	dnolen: based on output-to option
16:46	dnolen	eric_normand: k this sounds good.
16:47	eric_normand	dnolen: and a slightly modified cljs.closure/path-relative-to
16:47	eric_normand	dnolen: I assume the browser can figure it out if it is relative
16:48	eric_normand	dnolen: but I am testing on another project right now that serves up files over http
16:51	mtm	darrickw: just caught the tail end of your thread: are you having a problem with an NPE when trying to use :source-map with :optimaztions :whitespace?
16:51	darrickw	yeah
16:52	mtm	it looks like "var CLOSURE_NO_DEPS = true" is being cons'ed into 'sources' in cljs.closure/optimize; I'm not sure why, but it seems wrong to add a string there
16:55	mtm	later the code tries to get either :url or :source-url from that string (which, of course, returns 'nil') and then call .getPath on it, thus NPE
16:57	mtm	this "var CLOSURE_NO_DEPS = true" is only added to 'source' when :optimizations is :whitespace, which is why things work in :simple and :advanced
16:57	mtm	/s/sources/source
16:58	dnolen	mtm: http://dev.clojure.org/jira/browse/CLJS-373
16:59	callen	ClojureWerkz: We don’t have a new company to record podcasts about but we have 3 new libraries to announce this year.
16:59	mtm	interesting, but is 'sources' the right place to add this?
17:02	dnolen	mtm: this capability is intended as far as I know
17:03	dnolen	mtm: but in this case I guess that could be added later the same way we handle the output-wrapper and stuff like that.
17:04	mtm	okay, but the code at closure.clj:726 is going to blow up when it gets to that string (source == "var CLOSURE_NO_DEPS = true")
17:04	mtm	yeah, sounds right
17:06	dnolen	mtm: hrm, but really we should probably just filter out things that don't have :source-url or :url ...
17:06	mtm	yup
17:10	dnolen	mtm: http://dev.clojure.org/jira/browse/CLJS-590
17:10	dnolen	darrickw: ^
17:11	mtm	thanks David
17:13	eric_normand	dnolen: ok, works when served from http
17:14	dnolen	eric_normand: cool
17:14	eric_normand	dnolen: I assume you would like a jira issue + patch?
17:14	darrickw	Thanks to both of you! :)
17:15	dnolen	eric_normand: yep
17:15	eric_normand	dnolen: ok, doing it now
17:23	mgaare	is it not possible to add a docstring to a defrecord?
17:24	eric_normand	dnolen: ok, the patch is there; 5 line change
17:29	dnolen	eric_normand: thanks will take a look!
17:38	dobry-den	im so glad lein has that "enable ironic name" switch. my first 5 clojure apps were named "*jure".
17:38	technomancy	hm; I should probably add a rate limiter to that
17:38	technomancy	5 is too many
17:40	dobry-den	sometimes you just need to hit rock bottom before you can improve as a person
17:41	dobry-den	5th one did it
17:41	eric_normand	now all of your projects are clj-* ?
17:42	xeqi	or literary characters?
17:42	eric_normand	or s/s/j/
17:45	dobry-den	yeah, that's the thing. Python has it easy with it's "Py" prefix.
17:45	noonian	is it possible to pass aggregate values as parameters to lein run? for example: 'lein run -m foo/bar {:baz "zap"}', the argument parsing is breaking it for me I think
17:45	dobry-den	Clojure has Clo* puns and *jure puns. Both of which are hard
17:45	dobry-den	and clj is just an ugly combination of characters
17:46	dobry-den	look at it
17:46	dobry-den	clj
17:46	technomancy	I'm glad we don't see a lot of foo4j-isms
17:47	technomancy	what language your library is implemented in is really not something I care about seeing in clojars search results
17:48	dobry-den	how about an oauth clojure library named Cloth
17:48	dobry-den	how cute is that
17:48	technomancy	it is, in the vernacular, totes adorbs.
17:49	callen	dobry-den: that's pretty cute.
17:50	eric_normand	I prefer the name "Rhododendron"
17:50	dobry-den	but that's the thing - how are you going to remind the world that you reinvented the java.net.oauth wheel in Clojure just because it's Clojure this time?
17:50	dobry-den	the only option is to name it Clothjure.
17:50	callen	nooooo
17:50	callen	Cloth was perfect :(
17:50	eric_normand	maybe clojAuth
17:50	dobry-den	i don't make the rules
17:51	dobry-den	the world's gotta know
17:51	eric_normand	I'd buy a library called Clothjure
17:51	dobry-den	i can serve that dish
17:51	eric_normand	lein buy clothjure
17:53	callen	I still think the best *-jure name was stolen by Seajure.
17:53	dobry-den	is that french?
17:53	dobry-den	no, it's my clojure oauth library
18:04	mtp	Seajure is pretty good
18:29	pandeiro	i'm getting java.lang.NoSuchMethodError: com.google.common.io.ByteStreams.limit(Ljava/io/InputStream;J)Ljava/io/InputStream; when trying to cljsbuild with cljs 0.0-1889 -- do i need to manually fetch the compiler somewhere?
18:34	supersym	pandeiro: you're using lein-cljsbuild?
18:35	pandeiro	yes
18:38	pandeiro	quick scan of m2 shows no com.google.common.* so i assume that is the problem but i can't see how to do an update
18:38	supersym	Im not sure on that cljs version number, 0.3.2 mentions 1806, but its at 0.3.3 now not sure if they bumped to that upstream number
18:39	amalloy	pandeiro: that's an exception you only get if you AOT against version x of google commons, and then run against another one
18:40	pandeiro	i tried with both 0.3.3 and 0.3.4-SNAPSHOT
18:40	pandeiro	amalloy: so i gotta clean something somewhere?
18:40	pandeiro	target?
18:40	amalloy	shrug the cljs build process is a complete mystery to me
18:41	supersym	amalloy: glad to hear I'm not the only one
18:42	pandeiro	all this is my latest desperate attempt to make the cljs/js divide invisible
18:43	dnolen	pandeiro: your problem sounds unrelated to CLJS or lein-cljsbuild to me
18:43	supersym	pandeiro: yeah it's probably in .m2 somewhere, stuff runs fine here... how about a `lein deps :tree`
18:44	supersym	see if/where conflicts might be
18:45	pandeiro	it doesn't happen when i do not specify a clojurescript dependency specifically
18:46	pandeiro	(it = http://sprunge.us/OBAB)
18:47	supersym	ok... I get the warning, then specify 1889 - works fine here too
18:47	pandeiro	k must be on my end then... i'll keep investigating
18:48	pandeiro	thanks for checking
18:48	supersym	ah guava, I had problems with that too
18:48	supersym	earlier
18:49	supersym	not sure what the cause was though, just that I couldn't get them to play nicely, and I didn't need it so bad that I probed for long
18:49	pandeiro	yeah lein cljsbuild 0.3.2 will compile my code fine if a cljs dep is not specified...
18:50	supersym	yeah...thats a bit odd
18:51	gcganley	hey I've been googling around for a tutorial of clojure for someone that has alot of experience with C++. I havnt been able to find any its bummed me out. there is the Java screencast from Hickey but i did'nt pull much actual coding from that, just alot of philosophical discussion about the design.
18:53	mlb-	I want to create an Erlang-like event manager in Clojure. Would I want to start with a kind of singleton?
18:54	supersym	mlb-: https://github.com/MichaelDrogalis/dire is based on erlang style supervisor, would that be something you could use?
18:56	mlb-	supersym: not quite, but thanks for pointing that out to me!
18:59	mlb-	In different words, I want a central pubsub object to receive all events, and then route the subset for which subscribers have registered
18:59	appendonly	one 'soft' attribute i'm finding hard with clojure is that the top-level namespace has many tokens. i'm having trouble holding the whole thing in my head, like i would with c or scheme. in the lisp world, i know common lisp also has many top-level tokens in the standard language, often with hungarian notation. are there any clojure-specific tools for vim that would help me here?
19:00	TimMc	appendonly: By "top-level namespace", do you mean clojure.core?
19:01	TimMc	There's nothing top-level about it, it's just another namespace.
19:01	technomancy	appendonly: one side-effect of learning clojure is that you will undoubtedly re-implement 3-4 functions in clojure.core; it's pretty inevitable.
19:01	noonian	gcganley: I would just look for examples of doing specific things in clojure that you know how to do in C
19:02	appendonly	technomancy :-)
19:02	appendonly	TimMc: so i could import core with a prefix, and reference everything as core.blah? that would help me in the short run,a nd ic ould do away with it later
19:02	akurilin2	Can a solid case be made for NOT using the destructuring :or to provide default values?
19:02	hyPiRion	appendonly: there are no hungarian functions in Clojure afaik
19:02	noonian	gcganley: and also try to write everything completely functionally without figuring out how to modify anything but instead returning new values
19:02	hyPiRion	appendonly: I found http://clojure.org/cheatsheet to be handy when I started with Clojure
19:03	appendonly	hyPiRion: cheers
19:03	noonian	akurilin2: :or and :as don't play well together, so if you want defaults for some but also want a handle on all the keys you have to do the or's yourself
19:04	TimMc	appendonly: You could, using :refer-clojure, but that's gonna look pretty ugly and mess with your editor's ability to indent things appropriately.
19:06	noonian	appendonly: you should only run into problems if you redefine things in your own code and then try to use the core implementation, you should also get a warning in those situations. If you bind a symbol to the same name in a let binding or something you just have to be careful not to call the original one expecting the default behavior
19:11	akurilin2	noonian, hm ok, I'm goign to have to look into that
19:11	akurilin2	thanks!
19:11	akurilin2	bbl
19:11	dnolen	gcganley: what kind of tutorial are you looking for? this is a quick intro http://adambard.com/blog/clojure-in-15-minutes/
19:15	gfredericks	I'm trying to convince myself that I know how to use primitives, but it's not going well
19:15	gfredericks	,(loop [^long x 0] x)
19:15	clojurebot	#<CompilerException java.lang.UnsupportedOperationException: Can't type hint a local with a primitive initializer, compiling:(NO_SOURCE_PATH:0:0)>
19:16	gfredericks	that error message communicates to me "you can't do the thing you're trying to do"
19:17	amalloy	gfredericks: [x (long 0)], although really 0 is already a long, so...?
19:18	gfredericks	amalloy: so primitives get used by default?
19:18	amalloy	the compiler can tell the type of literal values, and doesn't need any prompting from you to generate efficient code; hints are for when it can't already know
19:19	gfredericks	okay. so if my loop body just has = and + then I should be good
19:20	gfredericks	maybe I should learn how to examine bytecode :)
19:20	amalloy	gfredericks: have you tried nodisassemble?
19:20	amalloy	it makes it way easier to find bytecode
19:23	gfredericks	amalloy: never heard of it
19:23	amalloy	(println (no.disassemble/disassemble #(loop [x 1, y 2] (= x y))))
19:25	amalloy	eg, that uses primitive locals, but calls clojure.lang.Util/equiv(long, long), whereas if you use == instead of =, it calls clojure.lang.Numbers.equiv(long, long)
19:26	amalloy	dunno why, really, since those both just return (x == y)
19:28	gfredericks	amalloy: cool, I'll check that out, thx
19:41	Hari`	hi
19:41	callen	Hari`: hi
19:41	hashcat	Hi
19:42	Hari`	:)
19:42	callen	Hari`: FB?
19:42	Hari`	huh?
19:42	callen	Hari`: checking to see if you were somebody I knew that works at FB
19:42	Hari`	ah
19:42	Hari`	nope
19:43	Hari`	i work at a finance startup..
19:44	Hari`	california
19:44	Hari`	we use haskell..
19:44	hashcat	good lang!
19:44	Hari`	i joined this clojure irc chat for kicks..
19:44	Hari`	clojure seems nice too.. i'm new to functional programming etc.
19:45	Hari`	hi hashcat, are you in the haskell channel? :)
19:46	Hari`	lol
19:46	hashcat	I've learned Haskell for three years
19:48	hashcat	but I think it's useless now
19:49	Hari`	hmm
19:49	Hari`	you didn't use haskell for anything? (or, for any production code...?)
19:50	callen	Haskell is fine, but I don't really want to make production systems with it.
19:50	hashcat	Hari`, I wrote a genetic programming
19:51	hashcat	just for hobby
19:51	hashcat	no one use it for production here
19:53	hashcat_	Hari`, what's your company?
19:55	Hari`	FastPay
19:56	hashcat	it sounds fun
19:56	callen	My test runner of late: <up-arrow> (require '[clojure.tools.namespace.repl :refer [refresh]]) (refresh) (run-tests)
19:56	callen	too lazy to fix prism or quickie to work properly.
20:18	coventry	Is there already a function which will invert a map? I.e., #(into {} (for [[k v] %] [v k]))?
20:20	brehaut	coventry: clojure.set/map-invert i believe
20:20	callen	"Clojure: the function already exists"
20:20	technomancy	(comp (partial apply zipmap) (juxt vals keys))
20:20	callen	uh oh, people are pseudo-golfing now.
20:20	technomancy	~juxt
20:20	clojurebot	juxt is a little hard to grok but it's the best thing ever
20:21	callen	is the juxtaposition of applying the functions that hard to understand?
20:21	brehaut	callen: based on evidence: apparently so
20:21	scottj	callen: no, not that hard, it's a little hard.
20:23	gfredericks	(defn mjuxt [m] (fn [& args] (zipmap (keys m) (map #(apply % args) (vals m)))))
20:23	coventry	brehaut: Thanks.
20:23	clojurebot	No entiendo
20:24	callen	Should start a juxt jihad.
20:24	hashcat	I'm amazed that people in here is more than scala channel
20:24	callen	hashcat: I'm not at all. Clojue is nicer to use.
20:25	hashcat	callen: why not scala?
20:25	gfredericks	it's because scala is so easy that nobody needs to ask for help
20:25	noonian	and easier to look at imo
20:26	brehaut	its because nobody needs help if they have static types
20:26	noonian	clojure is I mean
20:26	coventry	Maybe scala people socialize on twitter. :-)
20:26	gfredericks	brehaut: the compiler tells you exactly what you did wrong and how to fix it
20:26	hashcat	I'm trying to choose one for next project
20:26	hashcat	scala or clojure
20:26	callen	gfredericks: every single time. Without failure.
20:27	callen	gfredericks: it never once fails to solve the halting problem and tell you exactly what's wrong.
20:27	brehaut	gfredericks: kind mismatch, you might need some phantom types
20:27	callen	"It looks like you're using an if statement, I think you meant to use a monad here?" - Scala Clippy
20:28	callen	then you use a monad, and your type signature is 4 times longer.
20:28	amalloy	(inc brehaut)
20:28	lazybot	⇒ 18
20:28	gws	"now you have two problems"
20:28	callen	actually, n problems, depending on whether or not you've stepped into the undecidable part of Scala's type system or not.
20:30	gws	s/two/#REF!/
20:30	callen	this is why I prefer stuff like what ambrose is doing. Because I can make the type checker shut the fuck up when I want it to.
20:31	hashcat	well, I have a good idea. how can I mix scala and clojure?
20:31	gfredericks	put some parens around the scala
20:31	brehaut	hashcat: with more difficulty than youwould in using core.typed ;)
20:31	callen	hashcat: don't. just use Clojure and core.typed if you really want types.
20:32	callen	realistically you should just learn Clojure and wait to use core.typed until you understand everything.
20:32	Raynes	hashcat: You said "good idea" and I thought you actually had one for a second there. :(
20:32	Apage43	this is like when folks wanted an available database and a consistent database so we put them in a bowl and mashed them up with a mortar and pestle and now we just have garbage data
20:32	callen	I think you'll find types matter less than usual in Clojure than in other dyn langs.
20:32	callen	you think less about specific types or reifications and more about "shape" and categories of things.
20:33	Apage43	(didn't bother to use the mortar and pestle properly, just used them both as mashing implements, because yes.)
20:33	callen	Apage43: "We defeated CAP theorem! We are Conan the Data Manglers!"
20:33	hashcat	I still would like to try mix them
20:33	callen	"We knew something everybody else didn't bWAHAHAHAHAHA GIVE US MONEY NOW PLZ"
20:33	casperc	wierd question: what is the reason that reading a namespaced keyword like ::reload/error results in an invalid token error?
20:33	callen	hashcat: don't.
20:33	Apage43	"So our database is P?"
20:33	casperc	(read ::reload/error)
20:34	hashcat	callen: type is not the only one I want
20:34	callen	partition tolerant as you don't care about the data being correct or getting an answer.
20:34	callen	hashcat: doesn't matter. don't do it.
20:34	hashcat	dsl in scala looks pretty
20:34	callen	Apage43: sounds solid to me.
20:34	casperc	it happens both using clojure build in reader and tools.reader
20:34	callen	hashcat: learn Clojure alone anyway.
20:34	callen	DSLs in Scala are horrific monsters, lol.
20:34	hashcat	callen: what's the problem??
20:34	lazybot	hashcat: What are you, crazy? Of course not!
20:35	hashcat	callen: Monster?
20:35	bbloom	hashcat: DSLs in scala rely heavily on the type system for implicit conversion and operator overload resolution
20:35	hashcat	is lazybot actually a bot?
20:35	brehaut	&(inc 1)
20:36	lazybot	⇒ 2
20:36	Apage43	casperc: ::blah resolves to :current-namespace/blah
20:36	Apage43	so ::foo/bar tries to become :some-ns/foo/bar
20:36	Apage43	,:a/b/b
20:36	clojurebot	:a/b/b
20:36	bbloom	hashcat: if you like that sort of thing, then scala's DSLs are neat. But if you're a Clojure person, it seems like a really round about approach: just use data.
20:36	Apage43	which.. should work it looks like =P
20:36	Apage43	,::a/b
20:36	clojurebot	#<RuntimeException java.lang.RuntimeException: Invalid token: ::a/b>
20:36	Apage43	or maybenot
20:36	casperc	Apage43: hehe
20:36	Apage43	it's not obvious which ns that should wind up in, at any rate
20:36	casperc	Apage43: it seems to want the symbol to exist in the other namespace
20:36	hashcat	bbloom, you've convinced me
20:37	Apage43	casperc: well
20:37	hashcat	a lot of bots lol
20:37	Apage43	,::fun-error
20:37	clojurebot	:sandbox/fun-error
20:37	Apage43	is fine
20:37	amalloy	Apage43: ::foo/bar will never resolve to :some-ns/foo/bar
20:37	casperc	Apage43: but to me that is wierd since I am just reading not evaluating
20:38	amalloy	it looks in the current namespace to see what foo is a namespace-alias for (say it's clojure.string), and then expands to a keyword in that namespace, such as :clojure.string/bar
20:38	Apage43	casperc: reading a keyword instantiates the thing though, since they are values
20:38	srruby	* (* 3/2 4/3)
20:39	Apage43	amalloy: ah.. so..
20:39	Apage43	,::io/funsies
20:39	clojurebot	#<RuntimeException java.lang.RuntimeException: Invalid token: ::io/funsies>
20:39	casperc	amalloy: yeah, but it means that when I try to read a file with that kind of keyword it will fail
20:39	amalloy	casperc: yes
20:39	Apage43	would resolve to clojure.java.io/funsies if I require clojure.java.io as io?
20:39	amalloy	Apage43: try it and see?
20:39	casperc	I am basicly looking for a way around it :)
20:40	amalloy	for this reason (and also data_readers.clj), you can't really just-read a clojure program without evaluating it, i believe
20:40	Apage43	yup
20:40	Apage43	https://www.refheap.com/18731
20:41	srruby	Why does the repl give 2N when I input (* 3/2 4/3)
20:41	Apage43	:: is craftier than I thought
20:42	casperc	I am trying to read a bunch of clojure files without having to eval them or load dependencies, and this gets in the way
20:42	Apage43	looks like you're in trouble then, since you can't properly read ::'s without evaling at least the ns form
20:43	casperc	and I can eval the ns form without first eval'ing its dependencies (i would think)
20:43	casperc	*can't
20:43	Apage43	pretty much
20:44	casperc	hmm
20:44	Apage43	this makes writing tools to manipulate clojure code a bit tricky
20:44	Apage43	since you'll wind up.. running parts of the program
20:44	coventry	You can't get by with just the ns form. Type metadata will burn you. https://github.com/clojure/clojure/blob/master/src/clj/clojure/gvec.clj#L34
20:45	Apage43	look at https://github.com/xsc/rewrite-clj
20:46	Apage43	which is not quite all the way to a reader. Conveniently stops a bit before you hit a lot of this. However, this also limits the how much knowledge you have about the code you've read
20:47	coventry	casperc: What do you want to do with it once you've read it in?
20:47	casperc	Apage43: that might be an option. I am basicly looking to extract things like docstrings and function names, so it might be enough
20:48	amalloy	srruby: 2N is a bigint, and clojure stores its rationals as a numerator/denominator pair of bigints
20:49	casperc	coventry: to expand a bit: crawl the code for metadata basicly and pop it into a database for searching etc and make a webapp out of it
20:49	callen	quick, somebody ask a question touches on Clojure internals that amalloy cannot answer.
20:49	casperc	which I have basicly done, but this one is tripping me up, annoyingly
20:50	callen	coventry: haven't you been doing a much of stuff with reading and mangling namespaces?
20:50	coventry	Why does "(ns a.b.c) (definterface d) (deftype e [^a.b.c.d f])" work, but "(in-ns a.b.c) (definterface d) (deftype e [^a.b.c.d f])" complain that it can't find the class a.b.c?
20:51	casperc	coventry: i think ns creates the ns if it is not present and in-ns does not
20:51	coventry	callen: Yes, I have. It was a trail of woe I have abandoned, but I have gotten far enough to get a tree casperc could use for his purposes.
20:51	callen	coventry: whyyyyyyy were you doing?
20:51	callen	*that
20:52	coventry	casperc: It was a response to callen's challenge to stump amalloy. I don't expect an answer. I think it is a bug.
20:52	casperc	ah :)
20:52	coventry	callen: My judgement was bad. :-)
20:53	callen	coventry: isn't it because a.b.c wasn't required before the in-ns?
20:53	coventry	callen: Don't think so. The in-ns version fails at the repl after the ns version has run.
20:56	amalloy	coventry: because in-ns isn't a macro, and ns is
20:56	amalloy	it wants a symbol, iirc
20:56	callen	fuck I think he's right
20:56	amalloy	like, the definterface/deftype is a total red herring; your in-ns call fails immediately
20:56	coventry	Oh, duh. Thanks, amalloy. :-)
20:56	SegFaultAX	You know what else is a red herring?
20:56	SegFaultAX	Communism.
20:57	callen	Apparently getting engaged makes people less funny.
20:57	callen	Unless you're Bill Cosby.
20:57	SegFaultAX	callen: Go watch Clue... then get one.
20:57	coventry	Anyway, casperc, if you want to read in a file, you can eval it into its expected namespace form by form with (binding [ns ns] (eval form)). Try to do it into a different ns, and you need to edit the form before you evaluate it, changing any references to the ns.
20:58	callen	WRRRRRYYYYYYYYYYYYYYYY - channel error; reason: {#method<channel.close>(reply-code=406, reply-text=PRECONDITION_FAILED - unknown delivery tag 1
20:59	SegFaultAX	True story, the progfun class most definitely does require working knowledge of Scala in particular.
20:59	SegFaultAX	Which is fine, but it's marketed as... not that.
20:59	casperc	coventry: thanks, i'll give it a go.
21:00	callen	if RabbitMQ were something I could wrap my hands around, I would be strangling it.
21:00	callen	my pain ratio for RabbitMQ and Datomic for the last 2 weeks is 10,000:1
21:02	casperc	coventry: I am thinking of maybe faking it by require'ing a core namespace with that alias. I don't really need the result, just things like the docstring and args
21:02	casperc	, (require '[clojure.set :as a]) (read-string "::a/asdf")
21:02	clojurebot	nil
21:02	casperc	crappy hack but it avoids me having to eval
21:03	coventry	Oh, yeah, if you just want functions and docstrings, that is actually a much less hacky way to do it. Just crawl (ns-map 'ns) for the vars with :arglists and :macro in their metadata.
21:05	casperc	thanks for the input. I am off to bed :)
21:06	coventry	The directory-crawling tools in tools.namespace will be useful, too.
21:13	coventry	And if you do edit the namespace references, you will run into fun things like the fact that dashes need to be turned into undescores in type metadata. E.g. "(ns a-b.c) (definterface d) (fn [^a_b.c.d am] 1)", not "^a-b.c.d". (Which gives the same exception as (in-ns a-b.c), which is why I was stumped by that silly question. Argh.)
21:50	AimHere	Sigh. I'm grappling with some Java library that wants a method annotated with something of the form @Foo(id="wibble"). which I want to emulate in a class made by gen-class
21:52	AimHere	So far, after hunting for documentation (best I've found is a couple pages in Chas Emerick's book), the syntax looks like I put something like ^{Foo {:id "wibble"}} before the method name in the ':methods' section of gen-class
21:52	AimHere	But no matter what I do, it's not working. What's the actual syntax I need?
21:53	AimHere	It happily accepts ^{Foo {"id" "wibble"}} or ^{Foo {:id wibble}} or many, many variations without so much as a comment
21:59	callen	deftype ^{java.lang.Deprecated true} MyClass
21:59	callen	gen-class :name ^{java.lang.Deprecated true} MyClass
22:00	AimHere	Yeah, but that's for the annotation @Deprecated
22:00	callen	so find the annotation class and set it accordingly.
22:00	callen	if that doesn't work for you, we can discuss my contract rate.
22:01	callen	also if AOT doesn't suit your needs, you're boned. aphyr was complaining about the lack of annotation support in proxy awhile back.
22:02	AimHere	Well in your example, if I was to annotate @Deprecated(baz="wibble"), that 'true' would be replaced by a map containing 'baz' and 'wibble'
22:02	AimHere	So it would look like ^{java.lang.Deprecated {baz wibble}}
22:02	AimHere	Trouble is, that I don't know if baz should be keyworded, or if wibble should be in a string, or if they should all be bareworded or what
22:02	callen	if you keep using the word wibble, I'll be giggling too much to help you.
22:02	callen	AimHere: use strings.
22:03	AimHere	Well I think if I have them both stringed, it fails to call the damn function, though I've lost track of which permutations I've tried
22:04	AimHere	Chas Emerick's book, or at least the two pages of it that google search gives me, seems to show that the 'id' should be a keyword
22:04	callen	well listen to him, not me.
22:05	ddellacosta	AimHere: are you trying to figure out how to add methods to a gen-class?
22:06	AimHere	I've added the method. I'm trying to annotate one
22:06	ddellacosta	AimHere: ah, okay, apologies.
22:08	callen	I love it when people post a second shorter version of example code and it could be shortened even further
22:08	callen	today it's select-keys and keys that people forget exist.
22:09	callen	,(let [orig {:a 1} new {:a 2 :b 3}] (select-keys (merge orig new) (keys orig)))
22:09	clojurebot	{:a 2}
22:09	callen	is there some reason to do the same with filter and into {} ?
22:17	amalloy	callen: were you reading http://stackoverflow.com/questions/18808048/clojure-merge-with-remove-keys-that-are-not-common/18811538#18811538 recently, or what?
22:18	amalloy	i mean, i guess it's not actually the same function, but it's closely related
22:24	callen	amalloy: no, some blog post.
22:25	callen	my version above actually matches the semantics of the version of their code. It's not slightly different or anything.
22:34	ddellacosta	any way to get nrepl.el not to scroll to the bottom every time I execute something? I'm constantly hitting ctrl-l in the buffer.
22:58	clj_newb_2345	anyone have a good exmaple of using clojure as a "markup" language
22:58	clj_newb_2345	I want to output a rather complicated text document, and I want things like (str "...") to be a raw string
22:58	clj_newb_2345	but to also have other clojure expressions compile to strings to be intot the document
22:59	clj_newb_2345	i.e. think: TeX, but with clojure instead of TeX's macro langauge
23:39	coventry	Is there a way to assert the length of a list in destructuring of bindings? Something like (let [[rc] '(1 2)] rc), except that just returns 1 instead of throwing an error because the list is too long.
23:41	bbloom	coventry: sadly, destructuring doesn't have a well defined behavior for non-matches against sequences (at least in my opinion)
23:41	bbloom	coventry: the best you can do is [rc & more] and then (assert (nil? more))
23:42	dnolen	coventry: or you can use core.match
23:42	bbloom	dnolen: heh, right that too
23:43	coventry	Checking & more is good enough for now. Thanks.
23:48	amalloy	bbloom: fwiw i think (assert (not more)) reads better
23:49	bbloom	amalloy: i don't think it reads any better or worse, but I do think it's less precise: It suggests that false might be an interesting value
23:50	amalloy	i also have a function somewhere (assert-length N coll), so you could (let [[rc] (assert-length 2 '(1 2))])
23:50	coventry	Yeah, I thought about doing that.
