00:00	danielcompton	dbasch does this look correct for comparing two byte-buffers? https://www.refheap.com/85670
00:04	dbasch	danielcompton: java.nio.ByteBuffer implements comparable, so you could just do (.compareTo b1 b2)
00:05	danielcompton	facepalm
00:06	danielcompton	dbasch that's why I was confused about the equality thing earlier
00:06	dbasch	it returns an int, so you want (= 0 (.compareTo ….))
00:07	dbasch	yeah, ByteBuffer wraps byte buffers in objects with useful methods
00:07	danielcompton	dbasch the nio version?
00:07	dbasch	yes
00:07	danielcompton	dbasch wait, there is only the nio version rihgt?
00:07	dbasch	yeah, I don’t think there’s another one
00:08	danielcompton	dbasch thanks! What is = comparing on two byte-buffers, reference or value?
00:10	dbasch	danielcompton: it will do this: http://docs.oracle.com/javase/7/docs/api/java/nio/ByteBuffer.html#equals(java.lang.Object)
00:10	dbasch	so it should work
00:11	danielcompton	dbasch what's the difference between equals and compareTo? They seem to be doing the same thing?
00:11	dbasch	danielcompton: compareTo is useful for sorting
00:12	dbasch	it puts them in order
00:12	danielcompton	dbasch ahh
00:12	dbasch	equals is binary
00:12	dbasch	compareTo is >, = or <
00:16	yeoj___	is there any function that will convert "some-var" to :some-var to some-var ? I know about names and keywords, but seems like nothing goes into some-var
00:17	dissipate	yeoj___, yep, a macro would
00:17	tolstoy	or intern
00:17	yeoj___	so in a macro i have to unquote?
00:18	tolstoy	I think some-var# generates a symbol for you.
00:19	yeoj___	ahh ok thats what i'm mising
00:19	Frozenlock	yeoj___: Is this what you are talking about? https://www.refheap.com/11818
00:20	yeoj___	Frozenlock: i think i need the opposite of mapify, i have a :thingy inside a macro, and i'm trying to pass :thing as part of a larger string
00:21	dbasch	,(name :thing)
00:21	clojurebot	"thing"
00:22	dbasch	yeoj___: isn’t that what you want?
00:23	ddellacosta	yeoj___: if you want a symbol from what dbasch did just do
00:23	ddellacosta	,(-> :some-var name symbol)
00:23	clojurebot	some-var
00:24	yeoj___	i must be thinking about it the wrong way... i'm trying to do something with this: https://www.refheap.com/85672
00:25	yeoj___	i've never really understood macros, and am just rewriting a bunch of boilerplate korma crud stuff
00:25	yeoj___	i guess i want to create a function, that has a function name as a string composition.
00:27	ddellacosta	yeoj___: here's a very simple way to do it
00:28	ddellacosta	,(defmacro defcrudfn [name] `(defn ~(symbol name) [args#] (println args#)))
00:28	clojurebot	#'sandbox/defcrudfn
00:28	ddellacosta	,(defcrudfn "foo")
00:28	clojurebot	#'sandbox/foo
00:28	ddellacosta	(foo {:some "args"})
00:28	ddellacosta	do'h
00:28	ddellacosta	,(foo {:some "args"})
00:28	clojurebot	{:some args}\n
00:28	ddellacosta	*d'oh
00:29	ddellacosta	anyways
00:29	ddellacosta	yeoj___: if you want to concat it, you can do this
00:29	ddellacosta	,(defmacro defcrudfn [name] `(defn ~(symbol (str "my-crud-fn-" name) [args#] (println args#)))
00:29	clojurebot	#<RuntimeException java.lang.RuntimeException: EOF while reading>
00:29	ddellacosta	whoops
00:29	ddellacosta	,(defmacro defcrudfn [name] `(defn ~(symbol (str "my-crud-fn-" name)) [args#] (println args#)))
00:29	clojurebot	#'sandbox/defcrudfn
00:29	danoyoung	i was wondering if someone could offer advice on how to repeatedly take 5K line from a file, do something with those 5K, and continue getting 5K more until the file contents are exhausted.
00:30	danoyoung	I'm new to clojure
00:30	ddellacosta	,(defcrudfn "foo")
00:30	clojurebot	#'sandbox/my-crud-fn-foo
00:30	ddellacosta	(my-crud-fn-foo "args")
00:30	ddellacosta	,(my-crud-fn-foo "args")
00:30	clojurebot	args\n
00:30	danoyoung	I have some files in S3 that I want to loop over and read, take the contents and then index them into elasticsearch using the bulk api.
00:30	yeoj___	ddellacosta: ok i'm trying to make sense of all that, 1 min
00:31	danoyoung	so far I have something like this: http://pastebin.com/3ETqp8Fg
00:31	ddellacosta	yeoj___: sure thing--if anything is not clear definitely ask
00:31	danoyoung	but I don't know how to grab 5K @ a time….
00:31	yeoj___	ddellacosta: thank you
00:33	dbasch	danoyoung: 5k lines at a time you mean?
00:33	danoyoung	yea
00:33	danoyoung	something like take 5000
00:34	dbasch	danoyoung: you have a sequence of lines, so you can do that, or you can partition it into chunks of 5k
00:35	dbasch	then doseq over the chunks
00:35	danoyoung	dbasch: this is what I have so far: http://pastebin.com/3ETqp8Fg
00:36	danoyoung	so I need to look into using the clojure.core/partition? I'm new to clojure….just need some direction….
00:37	dbasch	danoyoung: you could do something like
00:38	dbasch	(doseq [chunk (partition 5000 (line-seq rdr))] (index chunk))
00:38	dbasch	(doc partition)
00:38	clojurebot	"([n coll] [n step coll] [n step pad coll]); Returns a lazy sequence of lists of n items each, at offsets step apart. If step is not supplied, defaults to n, i.e. the partitions do not overlap. If a pad collection is supplied, use its elements as necessary to complete last partition upto n items. In case there are not enough padding elements, return a partition with less than n items."
00:38	danoyoung	ok…cool, let me look into those functions.
00:38	danoyoung	thanx!
00:40	danoyoung	dbasch: learning clojure has been pretty fun so far!
00:43	ddellacosta	danoyoung: awesome. :-)
00:43	dbasch	danoyoung: if you’re looking for a good clojure book, get The Joy of Clojure
00:43	danoyoung	great, thanx. Will do!
00:43	danoyoung	dbasch that worked like a charm! thank you.
00:43	dbasch	you’re welcome
00:46	mercwithamouth	hrmm can someone tell me why selmer is unable to find my index.html file even when the path is hard coded in? https://github.com/jamalburgess/pepper
00:47	servo	dafuq
00:47	servo	https://github.com/fogus/lemonad/blob/7e6137fed655777963ac7b74913c78073070adc5/lib/lemonad.js#L515
00:48	servo	https://github.com/fogus/lemonad/blob/7e6137fed655777963ac7b74913c78073070adc5/lib/lemonad.js#L470
00:49	mercwithamouth	lol!!!
00:50	beamso	mercwithamouth: i found that the selmer templates have to be under src
00:51	mercwithamouth	beamso: hmm really? i guess that's fine...good to know
00:53	mercwithamouth	beamso: yup! that does it...thanks
00:53	kenrestivo	servo: um, he's a fan of h.p. lovecraft and breaking bad?
00:59	yeoj___	ddellacosta: thats great i think i got it, thanks for your help.
00:59	ddellacosta	yeoj___: Great! Glad to hear it.
00:59	yeoj___	ddellacosta: i've been staring at macros like that for ages thinking d'oh
01:00	ddellacosta	yeoj___: it took me a while before it clicked. I think you just have to keep at it and eventually it'll become second nature.
01:01	ddellacosta	yeoj___: it's also really important to understand how symbols and vars work in Clojure--I found that a lot of my confusion about macros had to do with not understanding how those worked. So definitely read up on those if you haven't yet.
01:02	ddellacosta	yeoj___: ...as well as being clear about compile- vs. run- time.
01:06	tolstoy	mercwithamouth: Is compojure expecting index.html in /resources/public?
01:07	servo	watcher.core=> (🙈 '🙉 '🙊)
01:07	servo	Exception Death watcher.core/🙈 (NO_SOURCE_FILE:1)
01:07	servo	emoji all the symbols
01:16	mercwithamouth	tolstoy_: i assume the result says no. i assumed i could tell it where to pull the file from regardless but that wasn't the case
01:17	tolstoy_	mercwithamouth: I think (route/resource "/view") might do it. It's been awhile.
01:17	mercwithamouth	that comes from a previous clojurescript attempt i made wher I was allowed to pull from the public folder. i just believe client/server code should be 100% separated
01:18	mercwithamouth	tolstoy_: i think you're right...i believe that IS what I did...i can't remember. it was over a month ago and i've been inconsistent with my clojure/compojure studying
01:18	beamso	has anyone used om in anger?
01:18	tolstoy_	:)
01:18	tolstoy_	http://weavejester.github.io/compojure/compojure.route.html
01:18	tolstoy_	That :root thing.
01:19	servo	woo i have a legit question now after messing with emoji:
01:19	servo	watcher.core=> (map (comp byte int) "🙈")
01:19	servo	IllegalArgumentException Value out of range for byte: 55357 clojure.lang.RT.byteCast (RT.java:993)
01:19	servo	is there a way to coerce that into bytes?
01:20	mercwithamouth	beamso: it's on my todo list
01:21	mercwithamouth	tolstoy_: ah ha...i've heard of this so called 'documentation' thing
01:21	ddellacosta	beamso: what's going on?
01:21	mercwithamouth	i should really work through the project in web development with clojure before i go off on my own opposed to 'glancing'
01:21	tolstoy_	mercwithamouth: The thing about documentation is you kinda already have to know it to even know how to use the documentation.
01:22	mercwithamouth	ddellacosta: tell me you use Om as well
01:22	mercwithamouth	tolstoy_: true...
01:22	beamso	ddellacosta: i was wondering how good it is/isn't
01:22	ddellacosta	beamso: I use Om almost constantly
01:22	ddellacosta	er, that was for mercwithamouth I suppose
01:22	beamso	the things i've read about it (and react) and the tutes seem okay
01:22	mercwithamouth	om and nolen are a God send...that is all
01:22	mercwithamouth	ddellacosta: i will be harassing you when ready. =)
01:22	ddellacosta	beamso: it's good. It doesn't solve all problems, but it solves a lot of UX dev problems.
01:22	ddellacosta	mercwithamouth: oh, sure thing. :-)
01:23	beamso	do you use anything in particular for models or just plain javascript objects?
01:23	ddellacosta	beamso: for models--you mean for the app data we pass in?
01:23	beamso	yeah
01:23	beamso	i notice the tutes send EDN across but i was concerned about that one
01:24	ddellacosta	beamso: well, it requires maps or vectors basically. Otherwise you can't create a cursor, which is the abstraction that dnolen created to coordinate Clojure data structures with React
01:24	beamso	okay
01:25	ddellacosta	beamso: ...and I think that speaks to the biggest problem with Om, is that there are some somewhat confusing concepts involved that I'm still not sure are very clear to me--even though I've been using Om in production for months. But leaving that aside, it works well.
01:26	beamso	forgive my ignorance but what would these concepts be?
01:26	ddellacosta	beamso: not at all--well, I was talking about the cursor concept in particular. I think that's the one that is hardest to grasp, and its purpose is the least clear.
01:28	ddellacosta	beamso: although I think this explanation is decent: https://github.com/swannodette/om/wiki/Cursors, I would like to see something that is even more general. "cursors wrap up and manage updating Clojure data structures within the React render cycle" or something
01:28	ddellacosta	mercwithamouth: what did you want to ask about btw.? You were talking about testing routes yesterday, no?
01:29	ddellacosta	mercwithamouth: if you have something concrete I can help you with it more easily.
01:30	mercwithamouth	ddellacosta: just now getting to it. for starters...i'd like to just create a route that collects a few fields and know that it does indeed catch the data sent
01:30	mercwithamouth	two secs...i'll create a route now and push it
01:30	ddellacosta	mercwithamouth: k
01:41	mercwithamouth	ddellacosta: ok we can use this to get my feet wet https://github.com/jamalburgess/pepper
01:42	ddellacosta	mercwithamouth: k, so, what within that in particular do you want to work with/test/etc.?
01:43	mercwithamouth	like either from the repl or command line i'd like to be able to do something like http:localhost:8080/register:"user-name":"pass" and then see that something has happened correctly
01:43	mercwithamouth	^ new developer so i'm really not sure what to ask. i'm used to rails hiding a lot of this from me
01:43	ddellacosta	mercwithamouth: gotcha
01:44	ddellacosta	mercwithamouth: well, the first problem is that layout is throwing an error when I try to load up a repl
01:44	ddellacosta	ah, def -> defn
01:44	ddellacosta	also, content-type needs to be referenced
01:46	mercwithamouth	ahh hmm...disregard that. i'd just gotten to the point where selmer worked and I started to go through the code in web development in clojure where they change the template over to use selmer. let me go back
01:47	ddellacosta	mercwithamouth: also handle-registration is broken in pepper.routes.home, I just added an id arg to that fn for now
01:48	mercwithamouth	ok sorry about that. layout.clj is back to nromal and feel free to change handle registration. i'd even be fine if we were adding data to a map
01:48	ddellacosta	mercwithamouth: no worries
01:48	ddellacosta	one sec
01:50	ddellacosta	freaking noir
01:51	ddellacosta	mercwithamouth: I would suggest minimizing the use of noir...but I guess you're probably following someone's guide, no?
01:51	beamso	lib-noir?
01:51	mercwithamouth	ddellacosta: i am following someone but i'm not attached to any libraries..i'm very open
01:52	mercwithamouth	beamso: yeah i was going to use lib-noir
01:52	beamso	better to use validateur for map/record validation?
01:53	ddellacosta	yeah, I lazily call lib-noir noir
01:53	ddellacosta	hold on, making a refheap
01:54	beamso	oh, maybe i can use prismatic schema for validation
01:54	ddellacosta	mercwithamouth: so, I had to massage a few things in your code as I described--commented out noir for now--but this is a very simple way to test routes in the repl: https://www.refheap.com/85674
01:54	ddellacosta	mercwithamouth: it's probably way easier than you had imagined. :-)
01:55	ddellacosta	beamso: we have our own custom validation thing, but I've prismatic's schema definitely seems good
01:55	mercwithamouth	it is and that's exacty what i was looking for =P
01:56	ddellacosta	mercwithamouth: great! I think there's probably a way to get lib-noir's session working with that too, but I'd have to play with it a bit. However, you can test out a lot of the basics of passing values around this way to start.
01:56	ddellacosta	mercwithamouth: alternatively just use the default ring session stuff for now
01:57	mercwithamouth	so like would it be as simple as (r/request :post "/register" "name" "pass")?
01:57	ddellacosta	mercwithamouth: oh, I think you pass in a map, lemme see
01:58	mercwithamouth	like if i could do (ph/app (r/request :post "/register" {:user-handle "Jamal" :pass "pastry"})) that would be interesting
01:59	ddellacosta	mercwithamouth: this should be illustrative: https://www.refheap.com/85675
01:59	ddellacosta	mercwithamouth: yep, that's exactly what you can do.
02:00	mercwithamouth	ddellacosta: YUP!!! exactly what i wanted
02:00	mercwithamouth	thank you!
02:00	ddellacosta	mercwithamouth: those two lines of output after I call the handler are 1) the request dumped out in the fn, and 2) the redirect response. So you can get all of that easily.
02:00	ddellacosta	mercwithamouth: Great! Glad I could be of service. I'm going to go grab some lunch but let me know if you have more questions. :-)
02:01	mercwithamouth	Ok, I definitely will be back. this gives me enough to tinker around the way that I want to
02:02	ddellacosta	aweseom.
02:02	ddellacosta	*awesome
02:28	ivan	where do I get that neat macro to log all function calls and return values inside an expression?
02:30	ivan	I guess this could work https://github.com/flatland/useful/blob/develop/src/flatland/useful/debug.clj
02:36	amalloy	ivan: i doubt you want to log all function calls and return values. that's a lot of them
02:36	amalloy	but useful/? is pretty good for targeted debugging
02:40	ivan	thanks
03:01	michaelr525	hi
03:01	michaelr525	i
03:02	mengu	hi michaelr525
03:03	michaelr525	is lein-sub the commonly used plugin for development when your code is spread over multiple leiningen projects?
03:05	beamso	i'm unsure if you need a plugin for it : https://github.com/technomancy/leiningen/blob/stable/doc/TUTORIAL.md#checkout-dependencies
03:05	michaelr525	i'd like to reload code from a common project for example without restarting the repl..
03:05	michaelr525	ok, let me check that link..
03:08	michaelr525	beamso: thanks! looks like just what I've been looking for
03:30	mercwithamouth	hmm what's the difference between ring and ring-server...and why does the compojure-app template choose the latter as a dependency?
03:32	beamso	mercwithamouth: so you can do a 'lein ring server' at the command line and start the server
03:32	beamso	it should also let the source be recompiled on the fly (so long as you don't introduce any new dependencies)
03:34	visof	i have a bin file which need to use inside clojure, but this bin need some time to load things and then get result, i tried (sh "/bin/foo" "-q")
03:35	visof	what is the basic way to do this?
04:31	mercwithamouth	hmm are there any plans to have rows opposed to just horizontal tabsets with light table?
04:54	mercwithamouth	ahh how i miss emacs =P
04:58	visof	can i interact with utils which are reading from STDIN in clojure from inside the code?
04:59	visof	if i have program behaves like a shell, and waits commands to run from user, can i interact with it from inside clojure, to send commands and print outs ?
05:00	xsyn	read-line?
05:00	xsyn	,(doc read-line)
05:00	clojurebot	"([]); Reads the next line from stream that is the current value of in ."
05:02	visof	xsyn: nope, what i meant if i have a problem called foo, when i run like /bin/foo i got >> , and after >> should write my commands to execute, that's inside shell, but i mean inside clojure can i do this?
05:03	visof	something like open a channel between my program and clojure, and send commands to the program, and return back the results
05:04	xsyn	like nrepl?
05:04	xsyn	wait
05:04	xsyn	your program and clojure? what is your program?
05:05	visof	yeah like even lieningen
05:05	visof	xsyn: well we can suppose the problem is leiningen
05:05	visof	s/problem/program
05:05	visof	can i run lein from inside clojure?
05:06	xsyn	yeah
05:06	xsyn	hold on
05:06	visof	okay
05:06	llasram	https://github.com/pallet/alembic
05:06	llasram	Although may not be quite what you mean
05:07	llasram	Oh, you want to launch Leiningen (or whatnot) as a subprocess
05:08	xsyn	https://github.com/zcaudate/vinyasa
05:08	xsyn	vinyasa/lein
05:08	llasram	xsyn: But that's also in-process
05:08	llasram	Which I don't think is what visof is trying to get a handle on
05:08	visof	llasram: yep
05:08	xsyn	I'm really not clear on the problem space, so.. :)
05:09	visof	xsyn: sorry for my English, but i'll explain again, when you open your terminal, it's waiting you to enter command to exec, can i make this behaviour in clojure ?
05:10	visof	run anything which waits for me to enter a commands
05:10	visof	from inside clojure
05:11	visof	xsyn: llasram got it?
05:12	xsyn	No, but it might be my fault
05:12	xsyn	like a repl?
05:12	beamso	wouldn't you just read from system.in until you get a ctrl+d?
05:13	llasram	visof: It depends on the program, and is a general Unix programming problem
05:13	ddellacosta	visof: you are trying to execute shell commands in Clojure?
05:14	llasram	Mostly depends on whether the other process expects to communicate over just stdin/out or expects to control a terminal; in which latter case things can get hairy
05:15	llasram	Either way though, is largely out of scope for Clojure
05:15	mercwithamouth	hmm how would one get autocomplete to work with emacs/clojure
05:15	mercwithamouth	https://raw.github.com/clojure-emacs/company-cider/master/screenshot.png <--
05:15	mercwithamouth	i have cider installed...repl and everything works great as expected
05:16	ddellacosta	visof: not sure if this is what you want but check out https://github.com/Raynes/conch
05:16	visof	ddellacosta: llasram xsyn thanks
05:17	ddellacosta	mercwithamouth: Hmm, I got autocomplete working w/clojure, what did I do...
05:17	llasram	mercwithamouth: ac-nrepl ?
05:17	ddellacosta	mercwithamouth: ah, I installed auto-complete via emacs default (since 24) package manager
05:18	mercwithamouth	yeah i'm using 24.3
05:18	mercwithamouth	hmm what keys? it definitely worked with emacs-live which i don't want to use again
05:19	mercwithamouth	ok i got it
05:20	mercwithamouth	well basic autocompletion...not the list that they're showing in that screenshot...but this works for now...i'm back to using emacs
05:20	ddellacosta	mercwithamouth: my config looks like this if it helps: https://www.refheap.com/85678
05:21	ddellacosta	mercwithamouth: yeah, I don't have all of that either, perhaps needs a clojure-specific dictionary?
05:21	mercwithamouth	ddellacosta: thanks. yeah most likely
05:21	mercwithamouth	i'll play with it after i get some rest...good to be back on emacs...not that light table isn't very nice
05:22	ddellacosta	maybe ac-nrepl that llasram suggested would help too
05:22	mercwithamouth	beamso: eww =(
05:22	beamso	it works well enough for me
05:23	beamso	the code completion and warnings are nice
05:23	ddellacosta	now now, we are accepting of non-emacs editors here in #clojure
05:23	beamso	i haven't used it to connect to a repl though
05:23	mercwithamouth	ac-nrepl IS it
05:24	mercwithamouth	beamso: just playing around, i like intellij a lot. i'd assume their clojure setup is nice as well
05:25	ddellacosta	mercwithamouth, beamso: my boss uses it w/Clojure and likes it a lot
05:25	ddellacosta	I'm always giving him crap about not using the one true emacs though
05:25	beamso	i've used emacs for it as well
05:27	mercwithamouth	ac-nrepl then ctags... i'm a configuration junkie
05:27	mercwithamouth	i've never really mastered using ctags, i think it's time to do so
05:28	ddellacosta	mercwithamouth: me neither. :-/
05:58	CookedGryphon	does anyone know how to make midje print proper stacktraces? I'm getting an exception when I run a test, but no line numbers annoyingly
06:15	cfleming	mercwithamouth: you wouldn't have to with Cursive, of course :-)
06:16	cfleming	mercwithamouth: Cursive isn't a Jetbrains product BTW, although we're trying for the same quality level
06:17	cfleming	We have a ways to go yet, though.
06:23	ssideris	cfleming: is there anything obvious that you can do with emacs that cursive doesn't do in its current version?
06:23	cfleming	ssideris: Well, it has a lot more community support, so there's modes for a lot of things we don't support yet (Expectations, Midje)
06:24	cfleming	ssideris: It has better REPL integration too, e.g. we don't have macroexpansion yet, there's a few other things
06:25	cfleming	But I think Cursive is pretty competitive now - we have pretty complete Paredit, although again we're missing some details here and there
06:25	ssideris	cfleming: ok, thanks :-)
06:26	cfleming	The main issue is that Cursive resolves symbols statically in the editor, which requires support for libraries using macros
06:26	cfleming	So some libs that are very macro-heavy (Midje, Storm, Cascalog) are a little painful till I fix them.
06:26	cfleming	I'm planning an extension API for that (in fact I use it internally) but I won't open it until it's stable.
06:27	cfleming	It's getting there, bit by bit.
06:27	ssideris	cfleming: about paredit: there is a "feature" that I have impemented in elisp but isn't supported in emacs paredit out of the box: re-ordering s-expressions, and moving the cursor along with the moved s-expression so that you can move it a few positions easily
06:27	ssideris	I think it's useful in some situations
06:27	cfleming	ssideris: So moving an sexp up or down and moving the cursor with it?
06:27	ssideris	yes
06:28	cfleming	Yeah, I'm planning that soon - that would be really useful.
06:28	ssideris	I'm just mentioning it as an idea for a feature
06:28	cfleming	It probably means you don't need transpose any more, I guess
06:29	ssideris	oh it seems that you're way ahead of me :-) thanks for your work, even if I don't use cursive, I think it's good for the community that it exists
06:29	cfleming	I think Cursive is going to be pretty cool in a couple of months, I'm starting work soon on a bunch of features that will be difficult/impossible to do in Emacs (or other REPL based editors).
06:29	cfleming	We're already marking unused locals in the editor, which is really useful.
06:30	cfleming	And having a decent rename + find usages is really great
06:30	cfleming	But it'll take us a while to catch up with everything Emacs does right now
06:31	cfleming	Thanks, it's a fun product to work on.
06:32	ssideris	I'm intrigued by what you said about features being impossible in emacs
06:32	cfleming	Maybe not impossible, but difficult
06:33	cfleming	The main difference is that Cursive resolves symbols statically in the editor
06:33	cfleming	So for a particular symbol, I know where it was declared, and thus what type of thing it is
06:33	clgv	cfleming: I saw that unused locals features - it seemed it had false alarms on macros that have binding definitions
06:34	cfleming	That allows me to mark unused locals right now
06:34	cfleming	clgv: Really? I'd be interested to see a case of that.
06:35	cfleming	None of this will ever be perfect with Clojure unfortunately, the language is just too flexible to do everything in an IDE you can do with Java
06:35	clgv	cfleming: I think the examples where in compojure code that a student showed me in cursive
06:35	cfleming	But you can get a long way
06:35	cfleming	Ok - do you mean that the IDE said that it couldn't resolve symbols?
06:36	cfleming	Yeah, that's what I mean by the fact that macros will require some code to identify those symbols
06:36	clgv	ah right. that's the exact description
06:36	cfleming	The unused locals is something else - this is where for a let-binding or a function parameter, or something similar, Cursive will tell you if it's never used.
06:36	clgv	I mixed up unused locals with undeclare symbols, sorry
06:36	cfleming	No worries
06:36	cfleming	It's really useful, since that is nearly always a bug
06:37	cfleming	We'll be marking unused imports and requires in the editor soon too.
06:37	clgv	cfleming: I know that ccw does a lot of this editor features via static analysis as well. I always thought it shouldnt be that complicated to run an additional repl for the UI which can provide exact infos, is it?
06:37	cfleming	You could probably do this in Emacs, and of course you can always use something like Slamhound externally, but having it live in the editor is really nice
06:38	cfleming	clgv: I don't think ccw does anything statically, it's all done in the REPL, like Emacs or Vim would do it.
06:38	clgv	cfleming: yeah, I definitiely wont argue against nice to have features. I hardly use emacs ;)
06:38	clgv	cfleming: the outline is definitely static
06:38	cfleming	AFAIK they don't even provide rename right now.
06:39	clgv	auto completion and such is done via the REPL
06:39	cfleming	Hehe, yeah, I'm not trying to start an editor war by any means, it's just interesting to compare them.
06:39	clgv	yeah, thought so ;)
06:39	cfleming	Emacs et al never have the problem of undefined symbols, even if they're generated by some gnarly macro
06:40	cfleming	Although with a REPL you can't do anything with local symbols, only globals
06:40	cfleming	Swings and roundabouts
06:40	clgv	cfleming: but again, do you think it would be that complicated to combine the static analysis with information from evaluating the project?
06:41	cfleming	No, and it's something I've thought about. The issue is that you need a REPL, and you either wait for the user to set one up (and have no support till that's done) or you try to do it automatically
06:41	cfleming	But people do some crazy things with macros, you can get all kinds of side effects, or it can require odd startup.
06:42	clgv	cfleming: I'd choose the automatic option and separate it completely from any repl the user launches
06:42	cfleming	Storm creates a bunch of vars from fields of a Java class, so for that to work you have to compile + load the class, and there's no way to know from looking at the code that you need to do that.
06:42	clgv	but depending on the features some communication might be needed between that repl and a user repl
06:42	cfleming	clgv: but you can't automatically start a REPL and just try to load everything into it.
06:43	cfleming	The user would have to specify what they want loaded.
06:43	cfleming	I dunno, it's messy.
06:43	cfleming	But you can't do macroexpansion without a REPL - for the moment I'll be using whatever the user has open
06:43	clgv	cfleming: you could lazyily load the namespace as soon as they are needed because the user edits a namespace
06:44	cfleming	clgv: yeah, but that wouldn't load Storm's Java class
06:44	clgv	when you open an editor for a namespace it can be loaded in the background to provide needed information
06:44	cfleming	Yeah, you can do that. I'm not sure, I'm going to see how far fully static will take me - combining the information from the two would be tricky
06:45	cfleming	But it might turn out to be necessary
06:45	cfleming	I'm hoping not, though :-)
06:47	clgv	cfleming: well, how can you do anything useful for custom macros defining symbols or functions?
06:47	clgv	cfleming: I think thats the main problem that static analysis will not solve
06:50	cfleming	clgv: I have an extension API, which is what I use internally - I'll open that up.
06:51	cfleming	It's pretty simple, you basically provide a function that takes a form and returns a map that looks very like var metadata
06:51	clgv	cfleming: ah, the user can provide the syntax of custom macros so that cursive is able to interprete them correctly?
06:51	cfleming	Yup
06:51	cfleming	Well, not yet, only I can right now. But that's the idea.
06:51	clgv	so the most popular libraries can get those annotations like that
06:52	cfleming	Yeah, and people can write support for their internal macros.
06:52	clgv	interesting.
06:53	cfleming	I'll probably have a central repo (like DefinitelyTyped for Javascript)
06:53	cfleming	But people would be able to use their own extensions.
06:58	ddellacosta	hmm, what is the plugin for emacs which lets you close/hide clojure forms? is it available in clojure-mode by default? Not sure what to call that operation
06:58	clgv	ddellacosta: fold/unfold?
06:58	ddellacosta	clgv: yah, that sounds right...know how to do that w/clojure in emacs?
06:59	clgv	ddellacosta: no idea. I just wanted to suggest what name you could search
06:59	ddellacosta	clgv: ah, okay...will see if that helps find the package
06:59	ddellacosta	thanks
07:00	agarman	I've honestly never missed collapsed code in emacs
07:00	agarman	but if you want it
07:00	agarman	hs-minor-mode
07:00	agarman	should be available with emacs by default
07:01	agarman	C-c @ C-c
07:01	agarman	is the default keybinding
07:01	ddellacosta	clgv, agarman: d'oh, just found that via this stackoverflow question: http://stackoverflow.com/questions/1085170/how-to-achieve-code-folding-effects-in-emacs ...but thanks!
07:01	ddellacosta	agarman: yeah, I haven't really ever needed it, but figured I'd play with it and see if it helped at all
07:02	ddellacosta	agarman: I wanted to get rid of a require form in particular...
07:02	agarman	IMO, if a require form is so large you don't want to see it, you may have a module that is due to be split apart ;-)
07:02	agarman	but enjoy
07:03	mercwithamouth	peep
07:04	ddellacosta	agarman: generally I'd agree, but this is my base wrapper for my web app, and loads up a bunch of other libs to wrap them up into one main handler. The require block is almost as big as the code in the file!
07:09	clgv	o_O
07:10	ddellacosta	(I exaggerate...maybe one-third as big.)
07:17	martinklepsch	Anyone experience getting nothing but "[Opened /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/rt.jar]" when running an uberjar with "java -jar name.jar" ?
07:17	martinklepsch	I tried oracle jdk and openjdk, no luck
07:17	martinklepsch	(it's all on ubuntu in a docker container)
07:18	martinklepsch	oh and the command had a "-verbose" in it too
07:21	beamso	no logs from the application apart from that?
07:22	silasdavis	I'd like a function that truncates the number of children of any node to be less than n, where a child is either a either a key-value pair or an element in a sequence
07:23	silasdavis	so that I can print large structures without killing my terminal
07:23	silasdavis	does anyone know of an existing function that does this, or a nice way of doing it?
07:24	CookedGryphon	bind print-length
07:24	CookedGryphon	(binding [print-length 10] (pr-str (range 99999999))
07:24	martinklepsch	beamso, no... same problem as yesterday :/
07:24	beamso	oh.
07:24	beamso	it's still today for me :/
07:24	beamso	have you tried running something else in the container?
07:27	silasdavis	CookedGryphon, ah! I didn't realise that would act recursively across the breadth
07:28	martinklepsch	beamso, haha, that's fun
07:28	martinklepsch	I slept the 8 of the last 10 hrs
07:30	mercwithamouth	hmm any ideas on how to stop my server when (stop-server) gives a null pointer error?
07:30	mercwithamouth	ps aux i suppose
07:31	mercwithamouth	good enough...
07:33	xsyn	(pgrep)
07:34	master_op	hello, how can handle global variables for my probram
07:34	mercwithamouth	'(pgrep)
07:34	mercwithamouth	lol break damn you
07:34	master_op	program
07:34	mercwithamouth	jk
07:35	ddellacosta	master_op: need more context
07:35	master_op	i have a map that change frequently , how can i update it
07:35	ddellacosta	master_op: still need more context
07:35	agarman	master_op: more context, but in general global variables should be minimized
07:35	master_op	i have a map defined when program start
07:35	ddellacosta	master_op: why/when do you need to update it?
07:36	master_op	and i have a function to update this map
07:36	master_op	add some keyword/value every time
07:36	agarman	master_op: wrap it in an agent, atom or ref
07:37	master_op	i use ref but when i try to use contains? it tell me that it not supported on refs
07:37	agarman	master_op: but there's likely a better way to do whatever you're trying to do without depending upon a mutable variable
07:37	master_op	how can i do it ?
07:37	agarman	you have to (contains? @v)
07:37	master_op	ok
07:37	agarman	master_op: read http://clojure.org/concurrent_programming
07:38	agarman	or rather http://clojure.org/refs
07:43	CookedGryphon	Is there a way to make core.async print line numbers on its exceptions, it's really really annoying having it tell me there's an issue doing a take! from nil but not giving me a clue where that's happening....
07:55	gfredericks	CookedGryphon: haha :(
07:59	gfredericks	CookedGryphon: do you not at least have a stack trace?
07:59	gfredericks	I'd think there'd be line numbers from the core.async code at least
07:59	CookedGryphon	nothing, it just prints the message from the exception and nothing else
07:59	llasram	gfredericks: Unless tbaldridge has cut a new version, IIRC the last release includes some code (I assume accidentally left in debugging code) which just prints the exception
08:00	llasram	No trace, etc -- just the exception object
08:00	gfredericks	oh that's wonderful
08:00	CookedGryphon	it's better than failing silently like it used to iirc
08:01	gfredericks	my favorite thing is when an ExceptionInfo gets printed without the data
08:01	llasram	https://github.com/clojure/core.async/blob/master/src/main/clojure/clojure/core/async/impl/exec/threadpool.clj#L33
08:01	CookedGryphon	could someone change that to a print-stack-trace?
08:01	gfredericks	I bet you could monkey-patch it :P
08:02	llasram	Or locally install a snapshot build, or use Leiningen checkouts
08:02	CookedGryphon	I might actually do that, I'm already monkey patching the executor to tweak the threadpool on android
08:02	CookedGryphon	but hoped I wouldn't have to for my local unit tests
08:02	gfredericks	does anybody have a core.async utils lib yet?
08:04	gfredericks	cause if not I might have to make core.a-sink
08:04	llasram	ha!
08:05	gfredericks	it'll have a function for finding out how many messages are in a buffer
08:06	gfredericks	and for creating a lazy seq from a channel
08:11	gfredericks	stuart says: "The channel-to-sequence conversion seems like a questionable idea, making seqs that block."
08:12	gfredericks	any kind of IO-based seq is a seq that can block though, no?
08:12	llasram	I would say so
08:13	gfredericks	I wonder if he considers that questionable too
08:15	gfredericks	seque should be easy to write with core.async eh?
08:16	gfredericks	probably just as easy with one of those j.u.c queues though
08:16	gfredericks	although core.async would let you use the go macro without taking up a thread
08:38	mercwithamouth	ahh nice... ac-repl is now working
09:07	crispin	hey peeps
09:07	agarman	crispin: hello
09:07	crispin	what's some other ways of expressing (and (:key1 opts) (:key2 opts) (:key3 opts))
09:08	crispin	that is, whether a handful of keys are in a hashmap?
09:09	agarman	(if-let [{:keys [key1 key2 key3} opts] ...)
09:09	agarman	nvm
09:10	agarman	not equivalent
09:10	crispin	reading up on if-let now. heh
09:10	crispin	so many functions
09:14	agarman	(every? #(% opts) keys)
09:14	mpenet	,((every-pred :a :b) {:a 1 :b 2})
09:14	clojurebot	true
09:14	mpenet	,((every-pred :a :b) {:a 1 :c 2})
09:14	clojurebot	false
09:14	kaw_	How about (every? opts [:key1 :key2 :key3])?
09:14	mpenet	many ways to do this
09:14	mpenet	but many fail if entry val is nil :)
09:15	mpenet	or falsey
09:15	gfredericks	anything wrong with this impl of seque? https://gist.github.com/fredericksgary/2f6d21890bbe82ed5416
09:15	gfredericks	it seems at least better than clojure.core/seque since it doesn't drop exceptions
09:15	agarman	I prefer (every? opts keys) as you're able to use key values that aren't keywords
09:16	crispin	i got (every? opts #{:k1 :k2 :k3})
09:17	agarman	don't need set
09:17	agarman	,(every? {:k1 1 :k2 2} [:k1 :k2 :k3])
09:17	clojurebot	false
09:17	agarman	,(every? {:k1 1 :k2 2 :k3 3} [:k1 :k2 :k3])
09:17	clojurebot	true
09:21	gfredericks	TimMc: so in my team's chat room we have this chatbot that will do image searches
09:21	gfredericks	somebody just searched for "Gary Fredericks clojure" and up came your photo with the shoulder rodents
09:22	gfredericks	clojurebot: shoulder rodents \|would be\| an acceptable name for a rock band
09:22	clojurebot	Ik begrijp
09:27	CookedGryphon	Could someone help me write a version of alts which has an even stronger priority
09:28	CookedGryphon	i.e. I want to always take from the first channel as long as there's something there
09:28	CookedGryphon	and only when there's nothing to take look at the next channel
09:28	gfredericks	what does "when there's nothing" mean?
09:28	CookedGryphon	when there's no immediately available value
09:28	gfredericks	that sounds like what the :priority option already does
09:29	CookedGryphon	hmm, from my experience it seems to check them in order, but it still cycles through them
09:29	CookedGryphon	so if i have (alts! [a b] :priority true
09:29	CookedGryphon	it will check a first, but after it's taken something from a, it won't keep taking from a, it moves on to take something from b
09:29	gfredericks	hm.
09:29	gfredericks	I'll go try that.
09:29	CookedGryphon	I might be wrong and actually I've done something else wrong
09:31	gfredericks	that's my suspicion
09:31	gfredericks	given that alts! only takes one thing I'm not sure what you're even trying to describe
09:31	CookedGryphon	fair point
09:31	CookedGryphon	now I think about it, it was an utterly ridiculous question...
09:31	tbaldridge	alts! takes options as well gfredericks
09:32	tbaldridge	(alts! ports & {:as opts})
09:32	CookedGryphon	what he means is, it's only taking one thing from one channel per alts! call
09:32	CookedGryphon	so my question is nonsensical
09:32	tbaldridge	ah right
09:32	gfredericks	haha "takes one thing"
09:33	CookedGryphon	I think the issue is my underlying structure needs a rethink
09:34	gfredericks	I tried to test this out and my code is hanging :(
09:34	gfredericks	oh I think it gave me a vector of way too many nils
09:34	gfredericks	because alts is happy to "take" from a closed channel
09:36	CookedGryphon	I'm making a system where events go in the top and there's a mult which broadcasts to various subscribers. These subscribers might themselves generate more events as a result of whatever they're listening for
09:37	CookedGryphon	I want these internally generated events to get processed first before working on any more externally generated events, so I have an external-input channel and a feedback channel, which I am trying to merge with alts! priority true and then doing mult on the result
09:38	CookedGryphon	and it seems to work in practice
09:38	CookedGryphon	but my tests are creating these, then doing onto-chan which closes immediately after the events are copied onto the input channel
09:39	CookedGryphon	and what's happening is that it's causing everything to close before all the internal events have been generated
09:39	tbaldridge	there's an option to onto-chan that makes it not close
09:39	CookedGryphon	yep, but then how do I know when it's done?
09:39	CookedGryphon	without just sticking a timeout on my tests
09:40	CookedGryphon	plus, I want to test that when the channel is closed, everything falls out of its go-loops and whatnot and is nicely cleaned up
09:40	CookedGryphon	and not sat there spinning or anything
09:40	CookedGryphon	(my tests also listen for the results of all the go blocks that get started to make sure everything has given up control by the end)
09:41	tbaldridge	it's hard to say without seeing the code
09:42	gfredericks	somebody plz write core.async.erlang
09:43	gfredericks	you could rewrite the go macro to support killing "processes"
09:44	tbaldridge	I've thought about it, but it gets pretty hard once you consider that a "go" may or may not be currently running or parked. It's easy to cancel a park, hard to kill a thread
09:44	gfredericks	yeah I was assuming you would only kill while parked
09:45	gfredericks	are rarely-parked gothreads a common pattern?
09:45	CookedGryphon	my issue is that I don't want to kill outright, I want to stop putting new input in the top, allow it to finish processing and then let me know when its finished so I can gather the results for my test
09:47	CookedGryphon	I sort of want to say "when all these go loops are parked, hand me control"
09:47	TimMc	gfredericks: This is acceptable to me.
09:48	CookedGryphon	is there any way of working out whether a go block is parked?
09:50	gfredericks	clojurebot: TimMc is the Gary Fredericks of Clojure
09:50	clojurebot	Roger.
09:53	clgv	TimMc?
09:53	clojurebot	TimMc is the Gary Fredericks of Clojure
09:53	clgv	:D
09:54	gfredericks	does seque actually suppress errors? I thought so but now I can't reproduce
09:54	gfredericks	,(->> (iterate dec 10) (take 20) (map #(/ 6 %)) (seque 5))
09:54	clojurebot	Execution Timed Out
09:54	gfredericks	&(->> (iterate dec 10) (take 20) (map #(/ 6 %)) (seque 5))
09:54	lazybot	⇒ (3/5 2/3 3/4 6/7 1 6/5 3/2 2 3)
09:55	gfredericks	&(->> (iterate dec 10) (take 20) (map #(/ 6 %)) (seque 5) (last))
09:55	lazybot	⇒ 3
09:55	gfredericks	,(->> (iterate dec 10) (take 20) (map #(/ 6 %)) (seque 5) (last))
09:55	clojurebot	Execution Timed Out
09:55	gfredericks	in my repl that gives an arithmetic exception
09:55	gfredericks	so...three different behaviors.
09:56	gfredericks	&(->> (iterate dec 2) (take 5) (map #(/ 6 %)) (seque 5))
09:56	lazybot	⇒ (3)
09:57	gfredericks	???
09:57	lazybot	gfredericks: Oh, absolutely.
09:59	TimMc	clojurebot: gfredericks?
09:59	clojurebot	gfredericks is a menace to bots everywhere
09:59	ticking	I think the edn spec is missing fractions, any thoughts?
10:01	gfredericks	ticking: I hadn't noticed that, that's interesting
10:02	gfredericks	ticking: easy to do with data readers though
10:20	ticking	gfredericks: yes, but the clojure.edn parser does handle fractions

12:04	KeithPM	Good day. I am trying to implement fibonacci using a dictionary. I tried memoize but could not figure out a function to memoize - I am seeking to implement without recursion. I created a ref to a map, updated it on each iteration and looked up values. It appears that all the updates that are performed within the for comprehension are lost when I leave the for. https://gist.github.com/kpmaynard/f8b539326bf2e903f402
12:05	TEttinger	KeithPM, for is lazy IIRC
12:06	gfredericks	KeithPM: you want let instead of def
12:06	gfredericks	KeithPM: and you can probably replace for with doseq and have it almost work
12:06	gfredericks	at which point you can remove your do
12:06	CookedGryphon	KeithPM: why do you want to do this without recursion?
12:06	KeithPM	gfredericks: OK, I will look up doseq
12:07	CookedGryphon	and memoize isn't a good fit because you have side effects everywhere, memoize works with pure functions
12:07	gfredericks	KeithPM: doseq has the exact same syntax as for
12:07	KeithPM	CookedGryphon: I was looking at a dynamic programming course and that was one of the techniques of handling certain classes of 'intractable' problems
12:07	gfredericks	memoize can only work if the recursion is memoized as well
12:07	KeithPM	gfredericks: Thanks
12:08	KeithPM	TEttinger: IIRC?
12:08	CookedGryphon	KeithPM: when you say without recursion, do you simply mean without blowing the stack by calling back into your function repeatedly? Because there's nicer ways of doing that
12:08	gfredericks	https://github.com/Prismatic/plumbing/blob/master/src/plumbing/core.clj#L305-320
12:09	gfredericks	$google iirc
12:09	lazybot	[The IIRC \| INTEGRATED REPORTING] http://www.theiirc.org/
12:09	gfredericks	haha
12:09	CookedGryphon	:P
12:09	KeithPM	CookedGryphon: yes, I know some really neat approaches. I was trying the memo approach for savng subproblems that have already been solved
12:10	TEttinger	if I recall correctly
12:11	KeithPM	TEttinger: OK - cool :) I'll memoize that one LOL
12:11	clgv	KeithPM: for the dp approach you'd just use a loop-recur with a loop variable to fill the dp-vector
12:12	KeithPM	clgv: But in the case of exponential problems like Fib, you still perform fib(n) multiple times right?
12:13	gfredericks	,(defn fib [n] (get (reduce (fn [m n] (assoc m n (+ (m (dec n)) (m (- n 2))))) {0 1 1 1} (range 2 (inc n))) n))

12:15	gfredericks	^ that guy is lonely because other fibonacci numbers are so far away
12:15	KeithPM	gfredericks: I will take a look at that
12:16	gfredericks	KeithPM: it's really common for algorithmic stuff like this to be solvable without any state/side-effects etc
12:16	gfredericks	the lazy seq approach is even more common than building up a vector though
12:16	adsisco	i have a function that f [index i, index j] that generates a float value, how do i use it to populate a matrix in clojure?
12:17	KeithPM	clgv: What I was referring to is that in the recursion tree you find the same problem occurring on two sides. The approach we're looking at is saving a problem the first time you meet it and check each new subproblem to determine whether it has been solved already
12:17	adsisco	[[(f 0 0) (f 1 1)] [(f 1 0) (f 1 1)]]
12:17	adsisco	i hope i'm making sense...
12:17	jcromartie	yeah
12:17	jcromartie	adsisco: you want for
12:17	KeithPM	gfredericks: Thanks. The power of reduce and map :)
12:17	adsisco	i could do loop in an imperative language
12:17	clgv	KeithPM: yeah that's memoization if you mean top-down, dynamic programming is bottom up
12:17	adsisco	is that the clojure way?
12:18	adsisco	jcromartie: a for loop?
12:18	jcromartie	,(for [i (range 1) j (range 1)] [i j])
12:18	clojurebot	([0 0])
12:18	jcromartie	oops
12:18	KeithPM	Yes I was doing bottom up
12:18	jcromartie	,(for [i (range 2) j (range 2)] [i j])
12:18	clojurebot	([0 0] [0 1] [1 0] [1 1])
12:18	KeithPM	clgv: yes I was doing the bottom up approach
12:18	jcromartie	clojurebot: for?
12:18	clojurebot	for is complected
12:18	jcromartie	hm
12:18	jcromartie	adsisco: anyway, for in Clojure is not a for loop, it's a seq comprehension
12:18	clgv	clojurebot: for \|is\| awesome
12:18	clojurebot	Roger.
12:20	adsisco	jcromartie ok, so i just map the function to the for to get my matrix right?
12:20	jcromartie	something like that
12:21	jcromartie	hm
12:22	jcromartie	let's say your function is str, so
12:22	jcromartie	,(for [i (range 2) j (range 2)] (str i j))
12:22	clojurebot	("00" "01" "10" "11")
12:22	jcromartie	that's probably not what you want
12:23	jcromartie	,(vec (for [i (range 2)] (vec (for [j (range 2)] (str i j)))))
12:23	clojurebot	[["00" "01"] ["10" "11"]]
12:23	jcromartie	that's better
12:23	jcromartie	adsisco: right?
12:23	jcromartie	(is forv a thing yet?)
12:23	jcromartie	,forv
12:23	clojurebot	#<CompilerException java.lang.RuntimeException: Unable to resolve symbol: forv in this context, compiling:(NO_SOURCE_PATH:0:0)>
12:24	jcromartie	it should be
12:24	sdegutis	Okay, I finally settled on having the production code be default, and with-redef'ing them out with test functions during tests.
12:25	sdegutis	Or the inverse, defaulting to the test version and resetting them in web-init.clj
12:25	jcromartie	(defmacro forv [bindings & body] `(vec (for ~bindings ~@body)))
12:26	jcromartie	there should be a macro that defmacros a macro wrapped in something
12:27	jcromartie	compmacro
12:27	gfredericks	so what's the use case for forv?
12:29	clgv	gfredericks: eager aggregation over nested maps
12:29	clgv	measurements etc.
12:29	adsisco	jcromartie: yup, thats really helpful, thanks alot!
12:30	clgv	but I'd implement it similarly to mapv with one collection
12:32	gfredericks	eagerness is only useful when your computation is tied to a stateful resource; and vectors are about indexed update/lookup
12:32	gfredericks	and indexed access seems hard to reconcile with list comprehensions
12:32	gfredericks	so my guess is this isn't actually useful very often
12:33	jcromartie	well in the case above, it was for creating a matrix, which is a great case for indexed lookup
12:33	gfredericks	for matrices I'd think something more specialized than for would be more useful
12:33	gfredericks	e.g., you probably don't need filtering with matrices
12:34	gfredericks	and you might not want the matrix impl to be concretized as vectors or lazy seqs
12:34	jcromartie	alright fine, no forv :)
12:35	gfredericks	unless you're doing tensor products you'd probably never need more than one clause in the for anyhow
12:36	KeithPM	Thanks all for your advice. I changed for to doseq and suddenly my ref was available all over. I will take another look at immutable DP approaches suggested here. Brain surgery in progress :)
12:37	adsisco	https://www.irccloud.com/pastebin/JQRXFSZ0
12:38	adsisco	create a wrapper function?
12:38	jcromartie	(map (partial get-in-distance-by-index json-data) (for …))
12:38	jcromartie	or #(get-in-distance-by-index json-data %)
12:39	clgv	gfredericks: eagerness is also usefull in the cases where you have to be pretty fast ;)
12:40	clgv	gfredericks: the above version of "forv" won't help for that though ;)
12:40	adsisco	jcromartie the partial fix works perfectly!?
12:40	adsisco	jcromartie: great!
12:40	gfredericks	clgv: fo sho

12:54	sc4n	Hi
12:54	te	hmm, clgv -- that works, but there are some issues. for instance, it will not work on strings, which is the input
12:54	te	there are also situations where it's unlikely, but /possible/ to have a number bigger than a bigint, so it will blow up

13:04	te	TEttinger: is that for me?
13:04	te	im just saying, i dont think it's possible to pad with a specified char using format
13:05	te	you can pad left with a space, but then need to replace those spaces with your desired char
13:05	TEttinger	te, yeah, the syntax for format strings is derived from java's syntax for it which comes from C, and so on
13:05	cbp	te: maybe you want apache.commons stringutils
13:05	te	cbp: yeah, sounds that way
13:06	TEttinger	the other way is to just check the length, subtract length from desired padded length, and use that many chars of padding

14:03	adsisco	amalloy: thanks!
14:09	arrdem	ew. Okay. so since the root of a var is volatile the JIT can never inline through it, right?
14:10	sdegutis	I wish you could do destructuring in conjunction with def.
14:10	sdegutis	I have some keys of a map that I want to put directly into this namespace.
14:10	arrdem	sdegutis: defn totally allows for param destructuring..
14:11	jcromartie	sdegutis: interesting idea
14:11	sdegutis	I basically have (def name (:name config))
14:11	sdegutis	Using destructuring with let would actually make it harder, since there would be shadowing.
14:11	gfredericks	sdegutis: https://github.com/fredericksgary/lib-4395 (defs-keys)
14:12	sdegutis	Oh boy.
14:12	sdegutis	Yep, macro time.
14:12	sdegutis	gfredericks: I may copy that.
14:12	sdegutis	Verbatim.
14:14	gfredericks	would a def-utils library be useful?
14:14	sdegutis	I think Clojure will be part of our homeschool curricula.
14:14	sdegutis	gfredericks: hard to say
14:14	amalloy	gfredericks: it'd just be a README, saying "dude, you don't need a million special kinds of def"
14:14	jcromartie	:)
14:15	gfredericks	deftwice
14:15	arrdem	lolwut
14:15	arrdem	better def it again just to be sure...
14:15	gfredericks	"Like defonce, but also works the second time."
14:15	amalloy	anyway, clojure.tools.macro already has the one def-util you need, name-with-attributes
14:15	jcromartie	(inc gfredericks)
14:15	lazybot	⇒ 61
14:16	gfredericks	I wonder how much of this karma is joke-related
14:16	amalloy	gfredericks: you could use def-utils to create def<nth> for all n up to some reasonable number
14:16	gfredericks	amalloy: and use my library forty-two to make english variants
14:17	amalloy	(def-one-hundred-eighty-eight-times foo 1)
14:18	gfredericks	no more implementing that one in every other project
14:18	amalloy	hah
14:19	gfredericks	,(defmacro def...? [name & args] (if (zero? (rand-int 2)) `(def ~name ~@args) `(def ~name)))

14:19	clojurebot	#<Unbound Unbound: #'sandbox/bar>
14:19	gfredericks	w00t
14:20	gfredericks	clojure should have antiprivate vars that can only be used from other namespaces
14:20	hyPiRion	gfredericks: sadly that one only works compile-time, so an AOT uberjared version would return the same result all the time, right?
14:20	tcrawley	cemerick: glad I could help
14:21	amalloy	hyPiRion: easily fixed
14:21	dbasch	I want a macro called deface that works just like defn, except it introduces random bugs you can’t know until you try
14:21	sdegutis	Clojure's got so much indirection with these vars.
14:21	sdegutis	I sometimes wish there were no vars.
14:21	amalloy	(defmacro def...? [name & args] `(when (zero? (rand-int 2)) (def ~name ~@args))) works, i think
14:22	gfredericks	,(defmacro definitely [name val] `(def ~name (try ~val (catch Throwable t# :no-sweat))))
14:22	clojurebot	gfredericks: Titim gan éirí ort.
14:22	gfredericks	clojurebot: whatever dude
14:22	clojurebot	It's greek to me.
14:23	llasram	clojurebot: Would it be so difficult to jut mumble something about exceptions?
14:23	clojurebot	Cool story bro.
14:23	gfredericks	,(defmacro definitely-not [& args])
14:23	clojurebot	#'sandbox/definitely-not
14:23	llasram	niiiice
14:23	llasram	(inc gfredericks)
14:23	lazybot	⇒ 62
14:24	gfredericks	see this library needs to exist
14:24	gfredericks	we just need a good pun for the name
14:24	amalloy	gfredericks: so misleading! (definitely-not (even? 2)) will make readers of my code think that math is broken
14:25	gfredericks	amalloy: what kind of weirdo gullible people do you get to read your code
14:25	amalloy	compilers are more gullible than any human being
14:25	gfredericks	,(def three 4)
14:26	clojurebot	#'sandbox/three
14:26	gfredericks	lol he just believed me
14:26	amalloy	(def largest-prime 85) ;; sure, okay
14:26	gfredericks	,(def _ "underscore")
14:26	clojurebot	#'sandbox/_
14:26	llasram	clojurebot is a he?
14:27	amalloy	gfredericks: were you around when i broke clojurebot by redefining 5 to be 2?
14:28	amalloy	llasram: it's not super-hard. you use reflection to modify the .value field of (Long/valueOf 5)
14:28	technomancy	isn't this something we make fun of ruby for making possible?
14:28	technomancy	I'll have to update my Tome of Mockery
14:31	llasram	amalloy: Ah. Yeah, ok. IMHO using reflection to stomp on private final (I assume?) fields is basically the same as memcpy()ing
14:31	llasram	So I'm somewhat less impressed :-)
14:31	gfredericks	amalloy: no way that's nutso
14:32	TimMc	:-(
14:32	gfredericks	Tim does not like it
14:36	llasram	Well, unless someone re-defined TimMc's smiley face to use ":-("
14:37	llasram	At this point we have no real way of knowing
14:39	hyPiRion	It's hard to know anything when everything is relative and changing.
14:41	gfredericks	except the undeniable objective fact that it's hard to know anything when everything is relative and changing
14:42	TimMc	amalloy: How's that?
14:43	amalloy	how's what?
14:43	TimMc	I did (.setAccessible (.getDeclaredField Long "value") true) but then this errors: (.setLong (.getDeclaredField Long "value") 5 2)
14:43	hyPiRion	gfredericks: but then it's not hard to know anything, it's hard to know anything with the exception of that statement
14:43	amalloy	TimMc: setAccessible mutates the Field object you have. you can't re-get the Field object
14:43	TimMc	Oh! Point.
14:44	amalloy	(doto (.getDeclaredField Long "value") (.setAccessible true) (.setLong 5 2)) or something
14:44	ystael	amalloy: does that break just one five or all the fives?
14:44	amalloy	all the (boxed) fives
14:44	llasram	Oh, language
14:44	amalloy	and since clojure boxes everything, that's all of them
14:44	TimMc	,(let [f (.getDeclaredField Long "value"), subject 5] (.setAccessible f true) (.setLong f subject 2) subject)
14:44	clojurebot	2
14:45	TimMc	D-:
14:45	hyPiRion	amalloy: not all the boxed fives?
14:45	amalloy	TimMc: ugh, don't do it to clojurebot again
14:45	llasram	,(+ 5 5)
14:45	clojurebot	4
14:45	hyPiRion	,(Long. "5")
14:45	clojurebot	5
14:45	TimMc	oops
14:45	amalloy	hyPiRion: true. all the ones boxed via Long/valueOf
14:45	TimMc	I should have use a bigger 5.
14:45	arrdem	,(+ 2 2)
14:45	clojurebot	4
14:45	arrdem	,(+ 5 5)
14:45	clojurebot	4
14:45	ystael	is there a numerical threshold above which boxed instances are not cached and shared?
14:45	jcromartie	wow, nice
14:46	TimMc	,(let [f (.getDeclaredField Long "value"), subject 5] (.setAccessible f true) (.setLong f subject 5) subject) ;; fixed?
14:46	clojurebot	2
14:46	hyPiRion	ystael: 128 or 256 I think
14:46	llasram	,(+ 5 5)
14:46	clojurebot	4
14:46	amalloy	ystael: +/- 128
14:46	TimMc	hahaha
14:46	amalloy	well, -128 to 127
14:46	llasram	,(let [f (.getDeclaredField Long "value"), subject 5] (.setAccessible f true) (.setLong f subject (Long. "5") subject))
14:46	clojurebot	#<IllegalArgumentException java.lang.IllegalArgumentException: No matching method found: setLong for class java.lang.reflect.Field>
14:46	arrdem	http://i0.kym-cdn.com/photos/images/newsfeed/000/613/012/2fa.gif
14:47	hyPiRion	TimMc: You have seen nothing yet
14:47	llasram	,(let [f (.getDeclaredField Long "value"), subject 5] (.setAccessible f true) (.setLong f subject (Long. "5")) subject)
14:47	clojurebot	5
14:47	TimMc	It restarts every 12 minutes, right?
14:47	llasram	,(+ 5 5)
14:47	clojurebot	#<IndexOutOfBoundsException java.lang.IndexOutOfBoundsException>
14:47	TimMc	And by 12, I mean 12.
14:47	llasram	Hmm
14:47	amalloy	llasram: that's the way i tried to fix it the first time
14:47	amalloy	but you made the same mistake i did
14:47	amalloy	instead of defining 5 back to 5, you defined 2 to 5
14:48	llasram	Oh, right
14:48	llasram	hah!
14:48	hyPiRion	hahah
14:48	amalloy	so now like every array access breaks
14:48	TimMc	I <3 FORTRAN.
14:48	amalloy	we never did find out if clojurebot's auto-restart actually fixes this problem
14:48	llasram	amazing
14:48	amalloy	hiredman gave it a manual hard-reset before waiting for that
14:48	arrdem	amalloy: one way to find out...
14:50	TimMc	,(let [f (.getDeclaredField Long "value"), subject 0] (.setAccessible f true) (.setLong f subject 42) subject) ;; if it will even run...
14:50	clojurebot	#<IndexOutOfBoundsException java.lang.IndexOutOfBoundsException>
14:50	TimMc	,(.getDeclaredField Long "value")
14:50	clojurebot	#<IndexOutOfBoundsException java.lang.IndexOutOfBoundsException>
14:51	TimMc	Amazing.
14:51	amalloy	TimMc: right, it's too late i think. you can no longer eval anything
14:51	dans	do most people really work with plain SQL migrations for big projects? nothing that generates SQL from some models defined in some clojure data structure?
14:51	amalloy	because eval uses the number 2 in an array somewhere
14:51	amalloy	,1
14:51	clojurebot	#<IndexOutOfBoundsException java.lang.IndexOutOfBoundsException>
14:51	TimMc	Got it.
14:51	arrdem	hahaha
14:51	hyPiRion	,'1
14:51	clojurebot	#<IndexOutOfBoundsException java.lang.IndexOutOfBoundsException>
14:51	arrdem	(inc TimMc)
14:51	lazybot	⇒ 58
14:51	TimMc	Only 28 points!
14:52	TimMc	I thought I had more.
14:52	hyPiRion	TimMc: well, since 2 is 5 and 5 is 2
14:53	gfredericks	wait we can prove a contradiction with this right? and then derive anything?
14:53	gfredericks	let's derive bugfixes
14:53	arrdem	gfredericks: quick prove P!=NP then we can keep our jobs forever
14:53	TimMc	amalloy: Do you know any way to get ahold of that interned 5?
14:53	ystael	TimMc: it's no longer a number ... it's a free man now
14:54	amalloy	TimMc: what do you mean?
14:54	gfredericks	arrdem: or P = NP but only for galactic algorithms
14:54	TimMc	Well, I'm trying to restore my REPL's notion of small numbers.
14:54	arrdem	gfredericks: this is also an acceptable outcome.
14:55	amalloy	i don't think you can do it if you've gone to the second level of broken like llasram did
14:55	amalloy	but if you've only broken it one level, it is reversible
14:55	TimMc	Just one level of fail.
14:56	amalloy	iirc this works: (let [five (long (int (+ (int 1) (int 4)))), field (nth (.getDeclaredFields Long) 3)] (.setAccessible field true) (.set field five (int (+ (int 1) (int 4)))))
14:56	TimMc	I'm having trouble figuring out what's going on here: https://www.refheap.com/85696
14:57	amalloy	fiddling with (Long. "5") doesn't help, because that's not the interned version
14:57	TimMc	Oh! Right-o.
14:57	llasram	Wouldn't (Long/valueOf "5") work? Or does the compiler do funny things?
14:58	amalloy	&(identical? (Long/valueOf "5") 5)
14:58	lazybot	⇒ false
14:58	llasram	Oh, interesting
14:58	amalloy	&(identical? (Long/valueOf 5) 5)
14:58	lazybot	⇒ true
14:58	llasram	That makes sense of course
14:58	amalloy	i don't know why, but apparently the string version bypasses interning
14:59	amalloy	llasram: does it? it should parse it as a long, then use the intern cache to get a Long
14:59	TimMc	valueOf probably just shortcuts, right?
15:00	amalloy	incidentally, three cheers for repl history: i just searched it for setAccessible to find this fix; i probably wouldn't have remembered it on my own
15:01	llasram	amalloy: Eh. It's not really clear to me why it should use the cache for the result of string parsing. Not saying it shouldn't -- it just doesn't seem unreasonable for it to not
15:01	hyPiRion	TimMc: Oh hey, if you find this sort of stuff funny, you should see this one: https://www.refheap.com/85697
15:01	hyPiRion	That one segfaults or makes your JVM spin up an infinite loop
15:02	amalloy	hyPiRion: do you really have to remove its FINAL modifier? once you make it accessible i think you can already write to it
15:02	amalloy	just like for Long
15:03	amalloy	maybe you're doing something weird i don't see there
15:04	hyPiRion	amalloy: it's static, which makes it a bit different IIRC
15:05	hyPiRion	at least I just checked, and it doesn't work with just .setAccessible
15:05	TimMc	,(+()()()()(*))
15:05	clojurebot	5
15:05	TimMc	It's back!
15:06	llasram	,(+ 5 5)
15:06	clojurebot	10
15:06	llasram	Yay!
15:12	TimMc	amalloy: I was able to fix it in my REPL by using "subject (+ 2 3)", but when I tried again with "subject 5" nREPL quit with an NPE. :-P
15:12	ystael	When building a custom coercion matcher in Prismatic/schema, if I'm trying to coerce into a multi-level record structure, it's supposed to recurse into coercing into the sub-schemas automatically, right?
15:12	amalloy	TimMc: my suggested fix didn't work?
15:13	TimMc	I didn't try it, since I was able to fix it a different way.
15:14	TimMc	"Bye for now!" https://www.refheap.com/85699
15:15	sdegutis	Related: https://medium.com/message/81e5f33a24e1
15:15	amalloy	TimMc: yeah, that's setting 2 to 5 again
15:16	amalloy	which really is a lot more disruptive than setting 5 to 2
15:17	KeithPM	gfredericks: I just finished digesting the DP code you shared this morning. Surgery over now :) Thanks
15:18	TravisD	I'm curious about the DP code now.
15:18	KeithPM	LOL… (defn fib [n] (get (reduce (fn [memo n] (assoc memo n (+ (memo (dec n)) (memo (- n 2))))) {0 1N 1 1N} (range 2 (inc n))) n))
15:19	KeithPM	I changed his m to memo… the 'm' was confusing me :)
15:19	KeithPM	I was seeking a way to use a map to store computed values
15:19	amalloy	KeithPM: and having n and m doesn't confuse you?
15:20	TravisD	Ah, so it stores the solutions in a dictionary and then if you ever need to recompute it, you can just look it up in the dictionary
15:20	TravisD	?
15:20	TimMc	amalloy: Ah, OK. Makes sense.
15:20	TimMc	sdegutis: Good quotes in there.
15:20	KeithPM	No… Actually I think of m and n as integer types… I was struggling OK? :)
15:21	KeithPM	TravisD: Yes that is the idea.
15:21	TravisD	cool :)
15:27	sdegutis	I'm reminded of that article that says the Clojure software ecosystem has no security baked in.
15:28	dbasch	sdegutis: in what context?
15:29	dbasch	security is not really something you can have “baked in"
15:30	jcromartie	sdegutis: what does that even mean?
15:31	benmoss	https://hackworth.be/2014/03/26/clojure-web-security-is-worse-than-you-think/
15:31	jcromartie	Clojure web security is exactly what I think.
15:31	benmoss	maybe you should ask the author to update his blog post
15:32	dbasch	agree with jcromartie
15:32	jcromartie	it's only "worse than you think" if what you think is "well I just wrote a networked service, I hope it's secure"
15:33	dbasch	and that’s the same in any language / platform really
15:33	jcromartie	like the Ruby secureheaders gem example… a library introduced in Jan 2013
15:34	dbasch	what would be useful is a reference with best practices for writing relatively secure clojure apps
15:34	jcromartie	or just hit up OWASP and educate yourself
15:35	jcromartie	then you'll be prepared to reason about potential security problems of any web app
15:35	dbasch	what I mean is, here are a few libraries that are relatively battle-tested in clojure, and here’s how to use them
15:36	dbasch	of course you should reason about the problems of apps first, the question is when you get to the point of
15:36	sdegutis	No computer is secure. Some are far worse.
15:36	technomancy	relevant https://medium.com/message/81e5f33a24e1
15:36	dbasch	“I need to build a password db, should I roll my own or is there a library that works reasonably well?”
15:37	nullptr	and remember, if you do an absolutely perfect job of web security in your application, someone can still sniff your server memory if your ssl vendor has a bug...
15:41	jcromartie	"perfect security" is basically the halting problem
15:42	jcromartie	if you're talking about depending on some other code to make your app secure at least
15:43	dbasch	in most contexts security is relative, e.g. nobody wants to be the app that got hacked and had to tell everyone to change their passwords everywhere because they were crappily hashed
15:43	lemonodor	i used to work with guys who did DRM for movie studios, they only browsed the web via BSD VMs they generated fresh every day. “it would cost someone $50K to buy a zero-day and target us, and we know it’s worth a lot more than that to them.”
15:44	jcromartie	lol DRM
15:46	llasram	jcromartie: Did you see this when it was making the rounds? https://plus.google.com/+IanHickson/posts/iPmatxBYuj2
15:47	jcromartie	yes
15:47	dbasch	llasram: that came to mind too
15:47	llasram	I'd actually wondered for a while what was up with the total non-response on breakage in e-book DRM. That article seems spot on, at least for that instance, and stopped my lols :-(
15:48	mdrogalis	cemerick: ping
15:48	storme	,(for [x (range 0 3) y (range 0 2)] { :x x :y y })
15:48	cemerick	mdrogalis: pong
15:48	clojurebot	({:x 0, :y 0} {:x 0, :y 1} {:x 1, :y 0} {:x 1, :y 1} {:x 2, :y 0} ...)
15:48	jcromartie	yeah, nobody cares about DRM
15:49	mdrogalis	cemerick: Is there a trick for using Austin in applications where browser-connected-repl-js can't come from the server?
15:49	jcromartie	like I don't believe for one second that anybody would even care to pay for a solution to movie studio DRM
15:49	jcromartie	they get it every other way you can think of
15:49	mdrogalis	Reading old IRC logs. Looks like setting up an endpoint just for that is what people are doing.
15:49	jcromartie	anyway </off-topic>
15:49	lemonodor	that post is somewhat correct. the incentives are definitely misaligned between, say, studios & player manufacturers. but the studios do care about their DRM getting cracked—though they only care that it holds up for about 30 days pas the street date.
15:51	lemonodor	jcromartie: there are offshore businesses making lots of money from subscription blu-ray pirating software.
15:51	jcromartie	interesting
15:51	storme	My big-o notation isn't the best, and I'm still new to Clojure... what would be the best way to turn ,(for [x (range 0 3) y (range 0 2)] { :x x :y y }) from O(n^2) to O(1)?
15:52	cemerick	mdrogalis: Nothing in Austin. People have hacked various ways to inject the necessary JS when they want. I think someone was working on a chrome extension to do roughly that.
15:52	llasram	storme: mu
15:52	storme	llasram, mu?
15:52	cbp	mooo
15:53	mdrogalis	cemerick: Interesting. Okay, thanks.
15:54	llasram	storme: Un-ask the question :-) Enumerating all those maps is necessarily linear w/ the number of maps you wish to emit
15:55	bgilbert	Hey guys, quick question.....does anyone know how to use apply with javascript interop in cljs?
15:55	storme	llasram, Ah, so there isn't anything that can be done about it?
15:55	bgilbert	I'm looking for something like: (apply (.foo bar) [1 2 3])
15:56	bgilbert	would be rewrite to: foo.bar(1,2,3)
15:56	llasram	storme: Not unless I've misunderstood what you're trying to achieve
15:56	bgilbert	I guess this question would extend to java interop as well
15:56	turbofail	well in java interop you basically can't do it
15:57	jcromartie	I've done it in cljs
15:57	turbofail	with CLJS you should be able to arrange to call the .apply method
15:57	llasram	bgilbert: well, there's slightly different solutions depending on whether the .bar method is a Java varargs method
15:57	llasram	oh, javascript
15:57	llasram	la la la
15:57	bgilbert	ah, well I'm primarily looking for the answer in js
15:57	bgilbert	ya
15:58	ghadishayban	what turbofail said, make the seq a js array and call js's .apply
15:58	bgilbert	turbofail: ah duh, thanks :)
16:07	Rockdtben	Hey all
16:08	Rockdtben	Is there a way to output the code I wrote in the repl to a text file?
16:12	llasram	Rockdtben: Not as a built-in general solution, no. If you're using a REPL which saves history, you can find the history file
16:14	amalloy	storme: i mean, you want to create n^2 maps. assuming that creating a map takes constant (non-zero) time, you can't help having an n^2 solution
16:15	amalloy	and if it takes more than constant time, then you can only get worse
16:16	storme	amalloy: I was under the same impression but wanted to be sure given I don't come from a CS background. Thank you!
16:19	stw	Rockdtben: if you use cider in emacs you can write the history to a file
16:19	stw	Rockdtben: (setq cider-repl-history-file "path/to/file")
16:23	Rockdtben	llasram: Thanks
16:25	Rockdtben	stw: Alright
16:25	Fare	hi. Is there a python parser in clojure?
16:26	tuft	Fare: don't think so, but there is jython
16:27	tuft	Fare: you could probably use their parser
16:27	Fare	tuft: that's an interesting thought
16:27	Fare	thanks
16:32	michaelr525	hi
16:32	michaelr525	should I build checkouts the first time before running 'lein repl' or 'lein run' in the parent project?
16:33	michaelr525	lein doesn't currently find the checkouts artifacts
16:33	technomancy	michaelr525: sounds like you're a bit confused about what checkouts are for
16:34	technomancy	they don't replace regular dependencies
16:34	michaelr525	i've added them under :dependencies in project.clj
16:35	michaelr525	linked as instructed under /checkouts
16:35	michaelr525	and ran 'lein run'
16:36	technomancy	sounds like the lib isn't declaring its deps correctly then
16:36	llasram	Well, michaelr525 -- what specific issue are you seeing?
16:37	llasram	technomancy's psychic powers are pretty good especially about Leiningen, but you never know :-)
16:37	michaelr525	Could not find artifact..
16:37	michaelr525	hmm.. i think the last thing technomancy said maybe
16:37	technomancy	michaelr525: yeah, that is unrelated to checkouts
16:38	noncom\|2	i'm trying emacs live, but when i jack-in into the simplest project created by lein, there is no "core" ns seen from the repl, what's wrong?
16:38	llasram	michaelr525: Has the checkout-dependency project never been deployed anyway, and exists only as a checkout dependency?
16:38	michaelr525	llasram: yes
16:39	llasram	I believe that is unsupported, and you need to at least `lein install` the dependency so that some artifact is present to keep the aether bits happy
16:40	michaelr525	llasram: ah, that's just what I suspected is happening
16:40	michaelr525	let me try that out
16:41	michaelr525	yes, that solved the problem..
16:41	michaelr525	thanks :)
16:41	llasram	np
16:42	tolstoy	noncom\|2: No idea if this is helpful, but if you've got one of the project files loaded in the buffer and have that buffer in focus, then call jack-in, it should work.
16:42	noncom\|2	tolstoy: yeah, that's what it should be, but..
16:43	michaelr525	llasram: btw, which plugin would you recommend for building checkouts?
16:43	amalloy	michaelr525: fwiw, the reason you need to do this is that checkout dependencies only "replace" source files. the pom files, dependencies, all that stuff, needs to exist for real
16:43	tolstoy	noncom\|2: Not that I use Emacs Live, so I don't know.
16:43	llasram	michaelr525: I have no such recommendation :-)
16:43	michaelr525	heh
16:43	michaelr525	oh btw guys, are you using smartparens or paredit?
16:44	llasram	<3 paredit
16:44	amalloy	paredit
16:45	Fare	if I wanted to write a parser for python syntax, which clojure tools would be best suited?
16:45	amalloy	i read smartparen's readme a while ago, and i recall it being kinda like a version of paredit that has one or two of the best features disabled by default
16:45	jcromartie	instaparse
16:45	Fare	jcromartie, thanks!
16:45	michaelr525	oh really?
16:46	whomp	is there a literal for a sequence, or do i have to use something like (seq [1 2])?
16:46	whomp	to get (1 2)
16:46	seancorfield	why not just [1 2]?
16:46	tolstoy	'(1 2)
16:47	seancorfield	(i.e., why do you specifically need it to not be a vector? or '(1 2) for a list?)
16:47	whomp	just wondering
16:47	amalloy	michaelr525: https://github.com/Fuco1/smartparens/wiki/Paredit-and-smartparens#random-differences reads to me as like...a radioactive disaster. why would you turn all this important stuff off?
16:48	technomancy	amalloy: yeah I don't get that at all
16:50	whomp	ah thx i get it now :)
16:51	michaelr525	I'm still getting myself fluent on paredit
16:51	michaelr525	I wonder if I can detach this ERC buffer to a separate window?
16:52	nullptr	michaelr525: M-x make-frame
16:53	michaelr525	haha it worked! thanks nullptr :)
16:53	michaelr525	now I know that it's the same buffer in both frames ;)
16:54	nullptr	heh, figured :)
16:54	nullptr	fortunately these are lessons you only need to learn once and they apply to other buffers equally
16:54	nullptr	(inc emacs)
16:54	lazybot	⇒ 3
17:09	noncom\|2	so why could cider fail to determine that the current buffer is a part of a lein project?
17:10	gtrak	how does cider know if a buffer is part of a lein project?
17:10	gtrak	(I'm pretty sure it just recurses up dir parents until it finds a project.clj)
17:11	gtrak	when you do cider-jack-in, but I'm not sure if it uses that technique for anything else.
17:11	noncom\|2	right, that's what lein is supposed to do i think
17:11	noncom\|2	but from the emacs live doc: "Project discovery is made possible because each buffer has a buffer-local variable named default-directory which stores the directory the file associated with the buffer is located within."
17:11	noncom\|2	so maybe the buffers "buffer-local" variable is damaged?
17:11	noncom\|2	how can i check for it?
17:11	gtrak	what's emacs live got to do with it?
17:12	noncom\|2	emacs live uses cider
17:12	gtrak	what relies on this?
17:13	noncom\|2	well, emacs live fully relies on cider for clojure repling, and that is what the documentation emphasizes
17:13	gtrak	err, I mean the variable specifically
17:13	noncom\|2	idk, i am a emacs newb
17:14	arrdem	Bronsa`: question about locals metadata if you've got a minute
17:14	Bronsa`	sure
17:14	noncom\|2	i guess that the variable "buffer-local" is common for emacs buffers to specify filesystem location of buffer contents if the buffer contains an open file
17:15	arrdem	Bronsa: (->> (clojure.tools.analyzer.jvm.core-test/ast (defn alter-var-root [^clojure.lang.Var v f & args] (.alterRoot v f args))) :init :methods first :body :ret :target :form meta) => nil. wat.
17:15	noncom\|2	and that cider relies on it to know where from the repl start was issued
17:15	noncom\|2	and passes the dir to lein and then you know what should happen
17:15	gtrak	let me say it another way, how do you know it's broken?
17:15	noncom\|2	but apparently something is broken
17:15	bbloom	Bronsa: have you started on the js analyzer? or are you just about to?
17:16	noncom\|2	i am not sure that the variable is broken since idk how to verify this assumption. so it is just an assumption. the main symptome that i suffer from is that the launched repl is fully unaware of the project namespaces
17:16	noncom\|2	and when i go (ns my-project.core) it creates a new one, empty one
17:16	Bronsa	arrdem: well, "v" in "(.alterRoot v f args)" has no meta, :form just contains the original symbol
17:17	gtrak	noncom\|2: sounds like just the parent-search thing is what's broken.
17:17	gtrak	ie lein is starting up the default project.
17:17	gtrak	which is not a project
17:17	noncom\|2	yeah, with just the user virtual ns.. so likely.. but this emacs setup is out-of-the-box, how can it be broken?
17:18	noncom\|2	emacs live is pretty popular
17:18	arrdem	Bronsa: sure, but it was my understanding (which apparently is wrong) that the same symbol object was used for "v" as an arg and here as a lvalue. So really the type hint exists only on the arg instance?
17:18	Bronsa	bbloom: I started working on it today, Alex created the repo a few hours ago https://github.com/clojure/tools.analyzer.js
17:18	bbloom	Bronsa: saw that, that's why i asked
17:18	bbloom	Bronsa: cool stuff. i know the cljs analyzer pretty well, so let me know if you find yourself head scratching. happy to help :-)
17:18	Bronsa	bbloom: yeah I'm going to start pushing working code in a day or two
17:19	Bronsa	bbloom: oh, thanks!
17:19	gtrak	Bronsa: when can I start relying on it in cider ;-)
17:20	Bronsa	arrdem: right, internally in tools.analyzer I use an atom to share that info between the :binding node and the :local nodes
17:20	Bronsa	gtrak: I'll let you know :)
17:20	noncom\|2	gtrak: so don't you have soe ideas on where to look to fix the problem?
17:21	gtrak	noncom\|2: yea, not sure, I'd try running lein and narrowing down stuff.
17:21	noncom\|2	you mean lein from the OS?
17:21	gtrak	doesn't sound like anything that's cider's fault.
17:21	gtrak	yea
17:21	noncom\|2	but emacs is an os!
17:21	noncom\|2	hah :)
17:21	noncom\|2	joke
17:21	gtrak	it just needs an editor!
17:21	noncom\|2	yeah :)
17:22	Bronsa	arrdem: you'll see that (-> ast :init :methods first :body :ret :target :tag) will be clojure.lang.Var as you'd expect
17:23	Bronsa	arrdem: using ast1 at least. ast doesn't run any of the passes
17:23	technomancy	noncom\|2: creating a new empty ns when you run (ns myproject.core) is totally normal behaviour
17:23	noncom\|2	gtrak: you're right, running from the host OS gives the same result
17:23	gtrak	welp
17:23	arrdem	Bronsa: something's fishy... that's nil for me.
17:24	Frozenlock	Is there any plan to add -?> to clojure?
17:24	noncom\|2	technomancy: but not when it is claimed that the repl session is guaranteed to start within the project...? or am i mistaken...?
17:24	technomancy	noncom\|2: starting a repl session in the project just means you can require project code and dependencies
17:24	gtrak	Frozenlock: I think that's what some-> does
17:24	technomancy	it doesn't mean that it will require them for you
17:25	Frozenlock	gtrak: It is! Thanks!
17:25	noncom\|2	technomancy: oh, i see..... so i have to (require) them..
17:26	Bronsa	arrdem: oh, it's :instance, not :target
17:26	Bronsa	arrdem: (->> (clojure.tools.analyzer.jvm.core-test/ast1 (defn alter-var-root [^clojure.lang.Var v f & args] (.alterRoot v f args))) :init :methods first :body :ret :instance :tag)
17:27	Frozenlock	,(:added (meta #'some->))
17:27	clojurebot	"1.5"
17:27	noncom\|2	just got too used to counterclockwise i guess.. strange... why does then ccw preloads all namespaces so they are already registered within the runtime.. ?
17:27	Frozenlock	Dang, how did I miss that.
17:27	Bronsa	arrdem: don't use the bare tools.analyzer `analyze`, always use tools.analyzer.jvm's `analyze` since you'll need all the passes.
17:27	arrdem	Bronsa: yeah that one bit me yesterday.
17:27	mmitchell	is there a fn to create a record from a map, but without knowing the record type until runtime?
17:28	michaelr525	tools.analyzer, how do you use it?
17:28	gtrak	mmitchell: what?
17:28	gtrak	you can dynamically pass constructors as functions..
17:28	gtrak	there's a ->MyRecord function generated.
17:28	mmitchell	ha, did that not make sense? :)
17:28	arrdem	woah where'd ast1 come from..
17:28	Bronsa	arrdem: also in this case :target becomes :instance a pass in taj transforms the host-agnostic :host-call node in the jvm specific :instance-call
17:29	Bronsa	arrdem: https://github.com/clojure/tools.analyzer.jvm/blob/master/src/test/clojure/clojure/tools/analyzer/jvm/core_test.clj#L18
17:29	mmitchell	gtrak: ahh ok right
17:29	gtrak	and map->MyRecord as well, that's probably more appropriate here.
17:29	arrdem	Bronsa: herp a derp. thanks.
17:30	Bronsa	arrdem: np. I know at first some differences between calling ta/analyze vs taj/analyze might be confusing, but they actually make sense :)
17:30	arrdem	Bronsa: sure. suggestions for pattern matching AST subtrees? I'm currently playing with var taint detection through blacklisting a few symbols and Var.set/Var.alter
17:32	Bronsa	arrdem: well, there's the datomic datalog interface that's pretty neat.. https://github.com/clojure/tools.analyzer/blob/master/src/main/clojure/clojure/tools/analyzer/ast/query.clj
17:32	arrdem	I gotta write a link rewriter so that just opens my emacs buffer :P
17:33	Bronsa	arrdem: though unfortunately I don't think you could make datomic a dependency for contrib libs :/
17:34	arrdem	Bronsa: I'd agree with that, which is unfortunate because I think my "whole program AST" thing is gonna wind up looking freakishly like a Datomic db with symbol -> ast mappings .-.
17:34	arrdem	hum. excuse for me to learn datalog.... taken.
17:36	arrdem	Bronsa: awesome. thanks for the help.
18:07	ToxicFrog	Say I'm using core.typed. Can I do runtime type checking with it, and if so, can I use that type checking to impose certain constraints on values?
18:08	ToxicFrog	E.g. I have a type defined that is a map with exactly a certain set of keys; can I add the additional constraint that some of the values fall within a given set, and check that, e.g., structures read from EDN satisfy that constraint?
18:09	arrdem	ToxicFrog: ambrosebs would appear to be offline, but I think the answer is no. core.typed does static checking, you want schema to do complex dynamic checks.
18:09	arrdem	$google prismatic schema
18:09	lazybot	[Prismatic/schema · GitHub] https://github.com/Prismatic/schema
18:10	arrdem	ToxicFrog: you can use static checks to prove the consistency of your own code wrt those data constraints, but to impose them on read or sourced values you need to do schema equivalent checking.
18:10	ToxicFrog	Alright, thanks.
18:11	ToxicFrog	The c.t docs talk about "tags" (runtime types) vs "types" (static types) and it's unclear whether it also supports runtime "tag checking"
18:11	ToxicFrog	...huh. I think I've broken core.typed, or possibly lein-typed.
18:12	ToxicFrog	'lein typed check' vomits out lots of duplicate 'start collecting <namespace>' messages interspersed with nils and then says 'found errors' without reporting any errors.
18:12	ToxicFrog	'lein typed coverage' straight up crashes.
18:14	numberten	is there a way to filter a collection by 'typeclass'?
18:15	amalloy	numberten: that probably depends on what typeclass means
18:15	numberten	so for example: (filter can-be-added collection)
18:15	numberten	returning a collection of things that can be used with the '+' function
18:16	amalloy	those typeclasses don't exist
18:16	amalloy	you can filter number?, which happens to be the set of things that is addable
18:16	numberten	so (filter can-be-added [1 2 3 :c \a]) giving you [1 2 3]
18:16	amalloy	but in general, for some function f, there's no way to check "is f callable on x"
18:17	numberten	i had a feeling, but I wanted to make sure I wasn't missing out on something
18:17	numberten	thank you, that answers my question
18:31	seangrove	Does it make sense to store a tree-structure in datomic, with each node being a datomic 'fact'?
18:32	arrdem	,(number? \1)
18:32	clojurebot	false
18:33	arrdem	,(char? \λ)
18:33	clojurebot	true
18:37	whomp	why is (fn [x] [x x]) valid but #([% %]) not?
18:37	hiredman	,(macroexpand '#([% %]))
18:37	clojurebot	(fn* [p1__73#] ([p1__73# p1__73#]))
18:37	hiredman	,(macroexpand '(fn [x] [x x]))
18:37	clojurebot	(fn* ([x] [x x]))
18:39	dbasch	seangrove: what is the tree for?
18:39	whomp	hiredman, now my head hurts
18:40	amalloy	hiredman: you don't need to call macroexpand there
18:40	amalloy	,'#([% %]) demonstrates the issue as well
18:40	clojurebot	(fn* [p1__122#] ([p1__122# p1__122#]))
18:40	hiredman	oh, right, the reader does the expanding
18:41	whomp	still don't understand
18:41	aperiodic	whomp: the second form expands into (fn [x] ([x x]))
18:41	nullptr	whomp: it's because it's trying to call [x x] as a function
18:41	aperiodic	whomp: can you see the difference?
18:41	nullptr	,([1 1])
18:41	clojurebot	#<ArityException clojure.lang.ArityException: Wrong number of args (0) passed to: PersistentVector>
18:41	nullptr	,(vec [1 1])
18:41	clojurebot	[1 1]
18:42	whomp	ah i see, thx :)
18:42	dbasch	this one should be in a faq, I’ve seen it asked several times recently
18:42	nullptr	everybody tries that at least once :)
18:43	dbasch	whomp: #(do [% %]) or #(-> [% %]) will do what you want
18:44	storme	This might be the wrong place to ask, but does anyone know of any companies in the bay area working with Clojure looking to hire?
18:44	nullptr	(map inc [hiredman dbasch])
18:44	arrdem	nullptr: sadly that isn't supported
18:44	nullptr	bah, it's lazy anyways ;)
18:44	dbasch	storme: prismatic for sure
18:45	dbasch	storme: there’s clojure at Twitter
18:45	arrdem	yelp...
18:45	storme	dbasch: Thanks, I'll check out Prismatic :)
18:54	martinklepsch	beamso, figured out the issue. docker problem
18:54	beamso	okay
18:59	Fare	looks like instaparse has trouble specifically with contextful lexing: either implementing it, or using an external lexer that produces non-characters, is painful.
19:01	arrdem	Fare: yeah instaparse wasn't designed for parsing arbitrary token streams
19:45	seangrove	dbasch: Sorry, what do you mean?
19:45	l1x	storme: yes, i think prismatic is big on clojure and they are hiring
19:46	dbasch	seangrove: what’s your use for a tree in a db
19:47	storme	l1x, Thanks!
19:47	seangrove	dbasch: Storying UI components n children, and being able to walk the tree up or down from a given node
19:47	dbasch	seangrove: how fast do you need that to be?
19:48	dbasch	i.e. is it for real-time rendering?
19:52	seangrove	dbasch: No, not especially fast - it's for debugging the state of the application. I'm not sold on doing it yet, I was just wondering about the difficulty (and performance) of doing something tree-like in datomic/querying with datalog
19:52	whomp	how do i install incanter? i ran the .dmg for my mac but my repl still can't find it for (require 'incanter.core)
19:53	whomp	is cljr the standard?
19:55	l1x	whomp: https://github.com/incanter/incanter/wiki#building-incanter
19:55	l1x	i would go with this
19:56	dbasch	l1x, whomp just add the incanter dependencies to your project.clj
20:19	whomp	trying to install cljr by running the jar, and i'm getting this issue: https://gist.github.com/michaeleisel/2bd83c8dc95f188b1262. any ideas?
20:20	amalloy	don't use cljr. just install lein
20:20	whomp	lein is a package manager as well?
20:20	whomp	what i was trying to do was install the incanter package so that i could use it in the repl, because running incanter's dmg doesn't seem to have done that
20:20	arrdem	whomp: nope. it's a maven wrapper, and maven is a dependency management system.
20:21	whomp	ok so my main goal here is to install incanter. any ideas on that?
20:21	amalloy	you want to create a lein project, and add incanter to its dependencies
20:21	whomp	(require 'incanter.core) gives an error still after installing the .dmg
20:21	amalloy	don't touch any dmgs, or install anything but lein
20:22	amalloy	get lein 2.x, not the 1.1.0 that cljr apparently comes with
20:22	whomp	amalloy, i have to always do that? there's no global package management? that seems kind of crazy, considering that there are lots of repls i might use it in - lighttable's, emacs's, the basic one in bash, etc.
20:22	blr	lein is clojure's dependancy management tool whomp
20:23	amalloy	there are other things you can do, but not any you should do. lein encourages repeatable builds, not system-specific installations. and creating a project is not some big difficult task that you should shrink from doing; it takes ten seconds
20:23	blr	you'll be pleasantly surprised how nice to use it is compared to other similar tools you might have used
20:27	whomp	i'll look into it, thx :)
20:33	blr	how I feel every time I go back to my typical work tools http://i.imgur.com/uV2LyXC.png
20:35	beamso	lucky you, in a way.
20:35	blr	beamso: right, it could be worse
20:36	beamso	you could be in visual studio all day every day
20:36	beamso	i found it tremendously difficult to try and get a rails job
20:36	blr	beamso: yeah, most jobs in my little city are .Net, which I've done a fair bit of and have no desire to return to
20:36	dbasch	blr: at least it’s not this: http://allenrecruitmentjobs.ie/wp-content/uploads/2013/07/worst-jobs4.jpg
20:37	blr	oh yeah, it's all relative.
20:38	blr	beamso: any chance of covertly rewriting stuff in F#? :)
20:38	amalloy	dbasch: i don't get it. that renders an "Account Suspended" page for me
20:38	beamso	amalloy: it was an image of a very bad plumbing situation
20:38	dbasch	amalloy: it’s an image of a plumber in a flooded bathroom
20:39	pdk`	i like this site
20:39	pdk`	one link and im already banned
20:39	pdk`	that's a new record for me
20:42	beamso	i've never seen anyone using f#.
20:43	S11001001	beamso: like, watched them program in it? Or knew someone who uses it?
20:44	beamso	uses it.
20:44	hiredman	I did some euler project problems in f#, and my last laptop had an ugly as sin f# sticker on it I spent a lot of time asking people if they had f# stickers to get
20:44	S11001001	beamso: Hi there.
20:44	beamso	hello!
20:44	S11001001	I use https://github.com/joshcough/f0/tree/master/fsharp/f0/f0 in production.
20:45	S11001001	beamso: so now you can't say :)
20:46	blr	pity MS has never made asp.net VS project templates for their alternative languages.. always though the uptake of ironruby/python and possibly f# would be higher if they simply did that
20:46	blr	err asp.net mvc rather
20:55	l1x	woo uglier than haskel?
21:16	whomp	why is this so? (= '() [])
21:17	joegallo	seqs have equality semantics
21:17	joegallo	such that that will work
21:17	joegallo	it's a feature!
21:17	joegallo	:)
21:17	joegallo	,(= [2 3 4] (map inc [1 2 3]))
21:17	clojurebot	true
21:18	joegallo	which is nice, it would be sortof lame if it were like, OH HO HO, BUT NO, those aren't equal, because you see, the latter thing returns a lazy seq and not a vector
21:18	Frozenlock	,(= '(#".") [#"."])
21:18	clojurebot	false
21:18	joegallo	now that's different, because regexes do not have equality semantics that make comparing regexes ever be = unless they are identical
21:18	joegallo	but you knew that ;)
21:19	Frozenlock	they are never equal
21:19	joegallo	(let [a #"."] (= a a))
21:19	joegallo	,(let [a #"."] (= a a))
21:19	clojurebot	true
21:19	Frozenlock	They are the same object
21:20	joegallo	did i not just say this?
21:20	Frozenlock	ah, yes, identical -_-
21:20	joegallo	no worries, brother
21:21	mdedetrich	hey guys, im coming to clojure from scala/java land, was wondering if there is a very good book/resource in regards to getting started
21:21	Frozenlock	It's still making me mad that you can't test for equality with regexes. Exactly for stuff like that.
21:21	Frozenlock	,(= [1 2 3 #"."] [1 2 3 #"."])
21:21	clojurebot	false
21:21	amalloy	Frozenlock: you can't test for equality with functions either
21:21	joegallo	heh, yeah
21:22	joegallo	mdedetrich: i hear good things about "The Joy of Clojure"
21:22	amalloy	it's really pretty similar; regex is conceptually a lot like a function
21:22	mdedetrich	joegallo: thanks, will have a look
21:22	Frozenlock	amalloy: Ah? never tried. Perhaps I should fill a bug :-p
21:22	amalloy	Frozenlock: no way. never going to change
21:22	joegallo	i believe there's a second edition that's like, right about to hit the presses, so make sure you get that, if you can stand the wait
21:23	amalloy	(= inc #(+ 1 %))? testing functions for equality based on anything but reference identity is impossible
21:23	arrdem	amalloy: it may not change in the core compiler :P
21:24	Frozenlock	,(= #(+ 1 %) #(+ 1 %))
21:24	clojurebot	false
21:25	Frozenlock	That's somehow conterintuitive considering that you can clearly see that they are the same thing. I mean, you could check the symbols and say 'oh, look, it's the same thing'.
21:25	gfredericks	,(assoc {} #"foo" 12 #"foo" 13)
21:25	clojurebot	{#"foo" 13, #"foo" 12}
21:25	arrdem	Frozenlock: sorta.. the compiler would have to know that + is commutative.
21:25	arrdem	gfredericks: ololololol
21:25	amalloy	Frozenlock: but you don't even have the symbols
21:26	amalloy	you just have two function objects. they're not even instances of the same class
21:26	gfredericks	Frozenlock: if something can't be done properly almost all of the time, why bother to do it at all?
21:26	Fare	what's the difference between "foo" and #"foo" ? How do I introspect the type of a value?
21:26	gfredericks	Fare: ##(type #"foo")
21:26	lazybot	⇒ java.util.regex.Pattern
21:26	amalloy	,(doc type)
21:26	clojurebot	"([x]); Returns the :type metadata of x, or its Class if none"
21:26	Fare	gfredericks, thanks
21:27	Frozenlock	amalloy: But I'm entering something into my repl! This is evaluated somewhere into the functions. Couldn't the equal function look at it before and see that it's the same thing?
21:27	Frozenlock	I suppose it would need to be a macro...
21:28	gfredericks	Frozenlock: where do you draw the line before giving up?
21:28	gfredericks	is inc the same as (fn [n] (+ n 17 -16))?
21:29	Frozenlock	I'd say the effect are the same, but the input isn't
21:29	gfredericks	you can put arbitrarily much computational effort into analyzing these things and you still won't cover everything
21:29	arrdem	Frozenlock: you cannot generally prove that two functions compute the same value. Example, solve the halting problem paired with itself or any other universal problem. If this is possible then you can compute infinite results in finite time, congratulations you broke the universe.
21:29	Frozenlock	yeah, that's shame :-p
21:29	gfredericks	you want equality only if the functions look identical in the source code?
21:29	Frozenlock	gfredericks: That would solve the regex, wouldn't it? ;-)
21:29	gfredericks	so (fn [x] x) != (fn [y] y)?
21:30	gfredericks	I think this would confuse the crap out of users
21:30	arrdem	gfredericks: hey you could prove that statically just by doing var renaming.
21:30	gfredericks	yep
21:30	Fare	gfredericks, why did you prefix that with ## ?
21:30	gfredericks	Fare: that's how lazybot knows to evaluate it
21:31	Fare	how do I get a list of methods for that class?
21:32	gfredericks	that is a tricksy question
21:32	gfredericks	at least if you meant what I think you did
21:32	gfredericks	if you meant what you said then the answer is http://docs.oracle.com/javase/7/docs/api/java/util/regex/Pattern.html
21:32	Fare	trying to introspect things to discover them
21:33	Fare	programmatically, if possible
21:33	gfredericks	but my guess is you want to know what clojure functions you can use it with
21:35	gfredericks	Fare: (use 'clojure.repl) and then check out apropos and find-doc
21:35	gfredericks	you're not going to able to search by class though, since that's not how clojure code is organized
21:36	Fare	I knew about apropos — thanks for find-doc
21:37	Frozenlock	about clojure.repl, is there a way to use it in every namespace?
21:37	Frozenlock	(not just in 'user' with lein profile)
21:39	gfredericks	Frozenlock: depends on how you're starting your repl
21:39	gfredericks	oh wait
21:39	gfredericks	we were just discussing this kind of thing a couple days ago
21:40	arrdem	Frozenlock: in _every_ namespace? no there shouldn't be unless you want to create clojure.core/doc and bind it to clojure.repl/doc or whatever.
21:40	gfredericks	the only way to get that kind of magic is to monkey-patch things in to clojure.core, but then you get into sticky situations depending on whether any of your code gets loaded first
21:40	gfredericks	leiningen didn't seem to have much to offer in that department, but a user.clj file should let you do whatever you need to sufficiently early
21:40	gfredericks	just don't tell anybody else that you did it
21:41	Fare	so if I have a server application in java, and I want some request to open a clojure repl for interactive debugging, how do I do that?
21:41	Frozenlock	Interesting
21:41	gfredericks	Fare: a request? like HTTP?
21:41	Frozenlock	living dangerously :)
21:41	arrdem	Fare: you use the nrepl library, drop an nrepl instance on an arbitrary port on an address behind your vpn ideally and pray.
21:41	Fare	what should my request handler do (after proper validation) to start a server that my emacs can connect to?
21:42	Fare	yes, it's all properly firewalled, of course
21:42	Fare	hopefully, my server should only listen on 127.x.x.x addresses
21:42	gfredericks	yep look at nrepl's start-server function
21:42	blr	Frozenlock: I have :repl {:repl-options {:init (use 'clojure.repl)}} in my lein user profile, but that will only load clojure.repl in the user namespace
21:43	Frozenlock	blr: Yeah, I tend to not stay in that namespace for long.
21:43	blr	agree that it would be nice to have clojure.repl available from any ns though
21:44	arrdem	eh if it's for debugging just monkey patch what you want into core
21:44	Frozenlock	getting to use the 'doc' function takes so much time that I just M-. and check the source.
21:45	gfredericks	Frozenlock: if you reload code in emacs frequently you don't have to worry about the load order as much
21:45	gfredericks	that's basically my approach
21:45	Fare	and from the emacs side, how do I initiate connection with localhost 12345 ?
21:46	arrdem	M-x cider-connect
21:46	Frozenlock	M-x nrepl <enter> the addresse
21:46	arrdem	or that
21:46	Fare	can I have several cider connections in the same emacs?
21:47	Frozenlock	Yes, but I find it confusing
21:47	Frozenlock	--> switch to the nearest nrepl buffer and .... Noooooo what have I done?!?!
21:48	Fare	Frozenlock, fair point. I can start a separate emacs with a different background color
21:48	Fare	but still... how do I tell cider which host and port to connect to?
21:48	Frozenlock	That'd be wise, especially if you connect to your production server's repl
21:48	Frozenlock	M-x nrepl <enter> localhost <enter> port (or something like that with cider)
21:49	arrdem	Fare: nrepl/cider will ask you for a port
21:50	Fare	the cider web page suggests M-x cider-connect but that command doesn't look like it exists in my loaded cider
21:50	gfredericks	M-x cider asks for a port
21:50	arrdem	anyone know of codebases which use inline, bare load, use or require?
21:51	Fare	oh, so it's M-x cider not M-x cider-connect --- thanks
21:51	Fare	maybe the README.md should be updated.
21:51	gfredericks	arrdem: clojure.core?
21:51	Jaood	how do you access the 'doc' commando when you cider repl switches from the user ns?
21:51	gfredericks	Jaood: (use 'clojure.repl)
21:51	arrdem	gfredericks: well yeah they do use raw load...
21:51	Fare	how different is the second edition of the Joy of Clojure ?
21:51	Jaood	gfredericks: thanks
21:53	blr	Fare: more on clojurescript and logic programming from what I understand
21:53	arrdem	blr: no core.typed plug?
21:54	blr	just going by what's here http://www.joyofclojure.com/2nd
21:55	Fare	blr: thanks!
21:55	Fare	I just bought the first edition :-/ Now wondering about the second...
21:56	blr	pity books don't have upgrade pricing :)
21:56	arrdem	the first was good, I read it from $UNIVERSITY library. I may get the 2nd.
21:56	blr	you went to php university?
21:56	arrdem	and burned it down after I graduated.
21:57	Jaood	JoC is a good second book I guess
21:58	Fare	thanks a lot for your support.

22:09	quizdr	anyone know what the "mies" stands for with some line templates?
22:09	quizdr	*Lein templates
22:10	beamso	a minimal clojurescript template, apparently
22:10	beamso	https://github.com/swannodette/mies
22:10	beamso	i can't retrospectively add a template to a project, can i
22:11	quizdr	interesting, how the letters "mies" come from that as an acronym, i don't know
22:12	fortruce	beamso: no, there is no way to merge a template into a project, but you can look at the template and use it to setup your project.clj
22:13	beamso	okay
22:29	zeroem	,(name (keyword "foo/bar"))
22:29	clojurebot	"bar"
22:29	zeroem	is that expected behavior for keywords?
22:29	gfredericks	yep
22:29	gfredericks	,(namespace (keyword "foo/bar"))
22:29	clojurebot	"foo"
22:30	zeroem	oh, so keywords are namespaced too
22:30	zeroem	ok, learned something new
22:30	zeroem	thanks :)
22:36	blr	the mies templates are named after the architect Ludwig Mies van der Rohe, because "less is more"
22:47	blr	whatever you do, don't lein new gaudí
22:49	andreh	Is there any tutuorial on PrimeFaces with Clojure for someone who already knows Java or Common Lisp?
22:50	blr	andreh: things like JSF are kind of anathema to clj web developers for the most part
22:51	andreh	blr: They normally prefer a Clojure equivalent?
22:52	fortruce	will with-redefs get shadowed by a local let?
22:52	blr	andreh: right, most clojure web apps are composed of discrete libraries, rather than built on frameworks. It's a nice approach, but it does require you to hunt around and take a while to figure out which tools you like
22:53	andreh	blr: nice, thanks
22:53	blr	andreh: Pedestal is the closest thing to a framework, but it doesn't provide much in the way of UI components like JSF https://github.com/pedestal/pedestal
22:54	blr	Luminus is a good way to get a taste for the first approach http://www.luminusweb.net/
22:54	blr	kind of a currated collection of libraries that work well together
22:58	bodie_	does anyone know of a good functional database besides datomic? I can't afford the licensing for the version that doesn't suck
22:59	beamso	functional?
22:59	bodie_	as in datomic
22:59	fortruce	bodie_: pretty sure datomic is the one and only
22:59	bodie_	http://www.infoq.com/presentations/datomic-functional-database beamso
23:00	bodie_	hrm
23:00	fortruce	bodie_: i haven't tried it yet, you enjoying it?
23:00	bodie_	no, because I can't afford the version that doesn't suck ;)
23:00	bodie_	so I haven't checked it out any further
23:00	beamso	you could simulate the immutability of that but i think it would take a lot of work
23:01	fortruce	it would basically take recreating datomic ;P
23:01	bodie_	well, it's an implementation of datalog, right
23:02	fortruce	but datalog isn't just for databases
23:02	beamso	actually, i was thinking of the immutable part, not the functional part.
23:03	arrdem	I SOMMON THE MIGHTY INTERTUBEZ. Please help me find Clojure/Java/Haskell/Scala benchmarks :P
23:03	TEttinger	getting an up-to-date one might be challenging, arrdem
23:03	beamso	http://benchmarksgame.alioth.debian.org/
23:03	fortruce	meh, benchmarks
23:03	TEttinger	reducers sped up clojure quite a bit, no?
23:03	bodie_	benchmeh
23:03	arrdem	beamso: that's where I'm looking right now.
23:04	bodie_	maybe I could learn haskell and work from this :P https://github.com/travitch/datalog
23:05	fortruce	anyone know how to use with-redefs to redefine a java ctor?
23:05	dissipate	isn't haskell a heavy syntax language?
23:05	dissipate	after perl i told myself i would never pursue a heavy syntax language again
23:06	TEttinger	arrdem, no scala here but https://github.com/jafingerhut/clojure-benchmarks
23:06	TEttinger	it has the other 3
23:06	bodie_	dissipate, pretty sure haskell makes perl look like clojure
23:07	bodie_	but everyone who likes it swears it's easy
23:08	dissipate	bodie_, no haskell for me then. haskell will end up as the new perl.
23:09	amalloy	"haskell will end up as the new perl". literally the first time that sentence has ever been said in the history of english
23:09	TEttinger	haha
23:09	arrdem	glad I'm not the only one chuckling at that
23:09	TEttinger	$google swearjure
23:09	lazybot	[polymatheia - Swearjure - hyPiRion] http://hypirion.com/musings/swearjure
23:10	TEttinger	clojure can be quite perlish
23:10	dissipate	arrdem, you are chuckling because you don't think it is true?
23:11	arrdem	dissipate: the absurdit/irony of the statement more
23:11	bodie_	amalloy, LOL
23:11	TEttinger	,(#(`[{~% ~@%&}] (+)) \: \[ \? \])
23:11	clojurebot	{\: \[, \? \]}
23:11	bodie_	it's kind of like saying zebras are the new abrams tank
23:12	bodie_	or potatoes are the new Mt. Everest
23:12	arrdem	^ this
23:12	bodie_	just... neurons sparking all over the place right now
23:12	bodie_	just left a job that was 120,000+ lines of perl spaghetti code...
23:12	fortruce	anyone know how to mock a java object?
23:12	bodie_	what has been seen cannot be unseen
23:13	arrdem	(inc bodie_) ;; karma cannot heal this pain but it may help

23:26	Kitty-	Hello, I am using Clojure to connect to a database and need to utilize . in my string. I've tried escaping it with \, so for example \. however it does not work. Any suggestions to try? The help would be much appreciated.
23:26	fortruce	Kitty-: can you show me what you mean?
23:27	Kitty-	fortruce: sure, let me come up with a pastie link
23:29	Kitty-	fortruce: so here is what I used before... http://pastie.org/9194703 however since "," is a special character I tried to escape it with ,\ in http://pastie.org/9194705 on line 12 however when I compile, it complains about "\" with a stack trace.
23:30	justin_smith	Kitty-: clojure complains about unneeded \ in string literals (and has differing rules for string vs regex literals
23:31	mange	Kitty-: Use \\. That'll put a literal \ in the string for the database to see.
23:31	ddellacosta	Kitty-: what are you using to run the SQL? Which clojure lib?
23:31	justin_smith	,"this\."
23:31	clojurebot	#<RuntimeException java.lang.RuntimeException: Unsupported escape character: \.>
23:31	justin_smith	,"vs. This\\."
23:31	clojurebot	"vs. This\\."
23:31	justin_smith	,(println "vs. This\\.")
23:31	clojurebot	vs. This\.\n
23:32	Kitty-	\\,
23:40	Kitty-	hmm, here is what I get http://pastie.org/9194732
23:41	Kitty-	It's not liking "(\"OID\"... should I use \\ with ", so \\" maybe?
23:42	justin_smith	I think your string escaping is not properly balanced there - are you missing a " after TEMPT_SPINSTER\" ?
23:42	justin_smith	*TEMP lol freudian slip
23:43	Kitty-	Lol
23:43	Kitty-	justin_smith: thanks...let me try adding the "
23:45	justin_smith	also if you have a repl available, it is much faster to test things like this in a repl
23:47	Kitty-	justin_smith: it compiled yaay. so when I execute the .jar against the server, i get an error http://pastie.org/9194741
23:47	justin_smith	Kitty-: what editor are you using?
23:47	Kitty-	I'm thinking it must have a ; however I'm not sure how to 'escape' those
23:47	Kitty-	justin_smith: notepad++
23:48	justin_smith	in some editors (mine for example being emacs) there is an "escaped string composer" mode that automatically escapes a region after you are done editing it
23:48	Frozenlock	really? What's the command?
23:48	justin_smith	in leiu of that in a simpler editor, maybe try interactively using that str invocation in the repl, and take a look at what it generates
23:48	beamso	ORA-00933 is more to do with the query or queries that you are executing rather than clojure.
23:49	justin_smith	Frozenlock: string-edit-at-point
23:49	justin_smith	Frozenlock: the awesome part is it even works recursively for recursively embedded strings
23:49	blr	silly emacs question, is there a better indentation strategy than that provided by clojure-mode? The way the body of the anonymous function is indented bugs me: http://i.imgur.com/RmgUpo5.png
23:50	Frozenlock	justin_smith: I don't appear to have this function... o_O
23:50	justin_smith	oh, it may be a package I have
23:50	justin_smith	Frozenlock: string-edit.el
23:50	Frozenlock	Unless it came later than 24.3.1, I would say so :-p
23:51	justin_smith	Frozenlock: package require string-edit
23:51	justin_smith	I forgot it was not a vanilla thing
23:52	Kitty-	justin_smith: any hints on what could escape a ";" perhaps? fwiw, I don't think a repl would work because the code has about 213 lines and then on top of that, it relies on compiled code originally written in java which I don't think clojure could do in realtime? So for example, it has to run off of a .jar which I don't think the repl 'does'
23:52	justin_smith	Kitty-: I'm just talking about the generation of that one string
23:52	Frozenlock	213 is nothing :-p
23:52	Frozenlock	Push that repl, cmon, push it!
23:52	Kitty-	Frozenlock: perhaps, but do you copy and paste 213+ lines in repl?
23:53	Kitty-	justin_smith: perhaps you have an example so I can understand further?
23:53	justin_smith	Kitty-: also, if you connect to your app by running an nrepl server from it, you can access data from the running process - you can make an atom and shove strings into it so you can experiment with them
23:53	Frozenlock	Kitty-: That's not the ideal, but I've pasted entire source code many times.
23:53	justin_smith	https://github.com/clojure/tools.nrepl it is really easy to host nrepl inside your app
23:54	justin_smith	make an atom, one of my favorites is a vector of a map, keys are args, vals are results
23:54	justin_smith	or you can throw timestamps in there if you have multiple things to look at ...
23:54	quizdr	does anyone know the emacs equivalent to the Light Table "add connection" command that you can use in Om to connect a script to a browser? I'm following the Om tutorial but using Emacs
23:54	Kitty-	justin_smith: hmm
23:55	Frozenlock	quizdr: Emacs doesn't have the magic LT connection. You'll have to configure a brepl
23:55	justin_smith	Kitty-: another option is to break your code down into smaller parts that can be tested for their output
23:55	justin_smith	this is good design anyway
23:55	beamso	for the om tutes i just saved then reloaded the browser
23:55	Kitty-	justin_smith: hmm yea
23:55	quizdr	but there is something the Om tutorial says to do about adding a script to the index.html, but it is not clear what it actually is, as it is done via this "connection" command
23:55	justin_smith	then you just (require ... :reload) on the ns as you update, and see what things do in a repl
23:56	Kitty-	justin_smith: I'm pretty sure it's just not liking ";" however I don't know how to escape that
23:56	justin_smith	,(print "\\;")
23:56	clojurebot	\;
23:57	beamso	quizdr: the script is so that when you save in lighttable it forces the browser to reload or reevaluate the javascript it's referencing. simply saving the clojurescript file, waiting for the recompile and reloading the html page should let you see the changes you want.
23:57	Frozenlock	justin_smith: string-edit is amazing
23:57	Kitty-	woohooo http://pastie.org/9194755 compiles
23:57	Frozenlock	How could I live without it?
23:57	clojurebot	Gabh mo leithscéal?
23:57	justin_smith	Frozenlock: yeah, I know, I wish I had it years ago when I was fucking with shell scripts more often :)
23:58	quizdr	beamso ah ,thanks
23:58	Kitty-	thanks for the tips... I'm gonna keep at it
