00:26	BRODUS	i'll try my question again since its quieted down, can derefing an atom ever throw an error? in the source the print method for atoms is same for other types that implement IDeref and they wrap the deref operation in a try/catch. I think this is only pertinent for Futures whose value isn't known yet, but I wondered if anyone else could confirm
00:26	BRODUS	heres the method: https://github.com/clojure/clojure/blob/bc186508ab98514780efbbddb002bf6fd2938aee/src/clj/clojure/core_print.clj#L387-L408
00:28	amalloy	deref on an atom can't throw an exception. it could theoretically throw an error like StackOverflowError if you happened to be at the end of your allocated stack already, but that's really just a problem in the calling code
00:29	amalloy	printing an atom could throw a StackOverflowError, if the data in the atom is circular, or if the atom points to itself
00:29	amalloy	,(let [a (atom nil)] (reset! a a) (deref a) nil) ;; no error from dereffing
00:29	clojurebot	nil
00:30	amalloy	,(let [a (atom nil)] (reset! a a) (deref a)) ;; but if you try to print that...
00:30	clojurebot	#object[clojure.lang.Atom 0x65e6d2ae {:status :ready, :val #object[clojure.lang.Atom 0x65e6d2ae {:status :ready, :val #object[clojure.lang.Atom 0x65e6d2ae {:status :ready, :val #object[clojure.lang.Atom 0x65e6d2ae {:status :ready, :val #object[clojure.lang.Atom 0x65e6d2ae {:status :ready, :val #object[clojure.lang.Atom 0x65e6d2ae {:status :ready, :val #object[clojure.lang.Atom 0x65e6d2ae {:status ...
00:30	BRODUS	,(println (atom "1234"))
00:30	clojurebot	#object[clojure.lang.Atom 0x5478a746 {:status :ready, :val 1234}]\n
00:30	amalloy	well, okay, clojurebot is configured so that that doesn't error, but most programs aren't
00:30	BRODUS	its weird they include the status field for atoms
00:31	BRODUS	its not useful
00:31	BRODUS	it looks like it will always be 'ready'
00:32	justin_smith	BRODUS: I think it's for all things that can be dereffed (many of which have a non-ready state)
00:32	justin_smith	,(promise)
00:32	clojurebot	#object[clojure.core$promise$reify__6999 0x38c25d61 {:status :pending, :val nil}]
00:32	BRODUS	right, but its still not unnecessary
00:33	BRODUS	i mean, its unnecessary
00:34	justin_smith	,(Object.)
00:34	clojurebot	#object[java.lang.Object 0x53202231 "java.lang.Object@53202231"]
00:34	justin_smith	that hex number is not neccessary either
00:34	justin_smith	it's just part of the printed representation
00:36	BRODUS	hmm, the hex code coudl be necessary if you were trying to see if objects were the same instance
00:36	justin_smith	BRODUS: identical? will tell you that
00:36	justin_smith	just like realized? tells you if a derefable is ready
00:36	justin_smith	but it's in the printed form too
00:37	justin_smith	in both cases
00:38	BRODUS	yeah but if you were just looking at logs the hex code is needed for that differentiation
00:38	justin_smith	the info is useful, it's concise, it's cheap to provide it, so why not print it when printing the object?
00:38	justin_smith	BRODUS: sure, and when I print a dereffable, it's nice to know if it's realized
00:38	justin_smith	BRODUS: what makes you think knowing if a dereffable is realized is not useful?
00:39	BRODUS	i never said that, i just think its confusing for atoms
01:16	TristeFigure	Hi. I'm having a little problem. I'm reading a .clj file path using the file dyn var, but what I get is a string representing the path of the file relative to its "source-path". For instance file's value is myproject/core.clj and what I want to is an absolute path or at least a relative path that encompasses the src folder, e.g. src/myproject/core.clj. So basically I need to get the current "source-path" value (i
01:16	TristeFigure	not necessarily in src, it can be in /test or in any other custom-set directory). I'm not sure how I could achieve something like this. There is a source-path var in the standard library but it seems it only contains the current file name+extension. Any idea ?
01:34	neoncontrails	TristeFigure: sounds like what you want is a file server. Clojure doesn't make this particularly easy, but have a look at Compojure: https://github.com/weavejester/compojure
01:40	neoncontrails	The idea is actually pretty simple though. You're basically just defining those strings that are the local path as the key, and returning the file as a value for those keys
01:40	elvis4526	Hello. I'm experiencing a OutOfMemoryError inside a relatively big clojure web app. Any tips on how to diagnose this ?
01:41	elvis4526	I know for the leak to happen, the app need to run for an extended period of time. Usually 2-3 weeks non-stop and more
01:43	neoncontrails	elvis4526: heh I'm working on a similar problem. Haven't solved it yet, but maybe we could help each other out
01:44	neoncontrails	It's running server-side?
01:44	justin_smith	elvis4526: you can profile clojure apps with visualvm or yourkit
01:46	neoncontrails	I always forget Clojure has back-end capabilities. That might be a better solution than client-side cljs for my problem, hmm...
01:49	elvis4526	neoncontrails: Yep it is.
01:50	elvis4526	justin_smith: I tried the memory sampler in justin_smith, however i'm not quite sure what the results are supposed to mean
02:10	elvis4526	Storing Ring requests inside an Atom isn't really a good idea right ?
06:38	lokien	can someone explain a fn pattern to me? I'm staring at it for half an hour now and I still don't know how it works
06:39	BRODUS	lokien: what do you mean?
06:40	lokien	BRODUS: I'll lpaste it
06:43	lokien	http://lpaste.net/2716934979316613120
06:44	lokien	BRODUS: I mean that function it's used with reductions
06:44	BRODUS	you're confused about how 'move' works ?
06:45	lokien	yeah
06:46	lokien	particularly that anon function
06:50	m1dnight_	I keep getting this "when-let decleration should be a vector" error but it doesnt specify a proper file where it occurs
06:50	m1dnight_	ive grepped all my when-let lines in my entire project and they all seem fine..
06:50	m1dnight_	any tips on how to debug?

06:52	lokien	BRODUS: I can clarify what it does
06:52	lokien	I just don't know how it does it
06:52	BRODUS	i'm just trying to work from the sexp with the hash map outwards
06:52	lokien	kay
06:53	BRODUS	oh ok
06:53	BRODUS	i didn't realize the keys would be evaluated in the hash map
06:54	BRODUS	after evaluation the hash map looks like {"<" go-left ">" go-right ...} and so on
06:54	BRODUS	each motion points to a function
06:55	lokien	uhm, ya
06:55	TMA	({...} word) returns a function. that function is passed position which is a two-element vector
06:55	lokien	so.. we extract a function from a map and use it on position?
06:55	lokien	I think I understand now
06:55	BRODUS	yeah
06:56	lokien	welp, thanks
09:43	ely-se	Is there a function like load-file that takes a URL instead of a String?
09:45	domgetter	ely-se: (eval (slurp url)) ? (this may be a very bad thing to do)
09:46	BRODUS	ooh, i didn't know slurp took a url
09:47	ely-se	domgetter: it was an XY question, actually. I want to execute clj files that are resources. It seems load does that
09:52	ely-se	thanks :)
10:44	justin_smith	you would need a read-string between slurp and eval
10:55	domgetter	Anyone know a good resource to learn what the term "middleware" means?
10:57	AimHere	Wouldn't wikipedia give you a rough overview?
10:59	domgetter	The description on wikipedia applies to any library I use. Are all libraries middleware?
11:05	domgetter	Here is my question in context: https://github.com/dakrone/clj-http/blob/master/src/clj_http/client.clj
11:05	domgetter	There are "middleware" functions in that file, but the wikipedia page talks about gluing programs together
11:05	domgetter	so why is the word being used two completely different ways?
11:06	domgetter	That's a bad rhetorical question. I guess what I should ask is, can the wikipedia page help me come to an understanding of the use of the term "middleware" in that client.clj file?
11:07	justin_smith	domgetter: a middleware is a function that takes a function as an argument and returns a new augmented function
11:08	justin_smith	domgetter: in a ring app, you have your handler which serves a request, and pass that to various middleware, like the one that takes a request, and returns a request which tracks a user session, for example
11:08	justin_smith	or one that takes a request, and returns a request where the request parameters are not mapped to keywords in a hash-map instead of being a raw string
11:08	justin_smith	etc.
11:08	justin_smith	s/not/now
11:08	domgetter	justin_smith: if I did that with channels, would the things which take stuff of off channels and process them be considered middleware?
11:09	justin_smith	no - but if you had a function that took a channel, and returned a new channel that did some special new thing for every event on the channel, that would be a middleware
11:09	domgetter	like a channel with a transducer on it?
11:10	justin_smith	exactly, the transducer there acts as a middleware
11:10	justin_smith	it wraps x, returns a new thing you can use as if it was x, but has a new feature
11:10	justin_smith	or a modified behavior
11:11	justin_smith	domgetter: in functional programming we often use composition of middleware in cases where OO programs would use inheritence
11:12	domgetter	and by composition here you mean functional composition?
11:12	domgetter	or possibly a more general notion of combining?
11:13	justin_smith	functional composition (though here it is technically function application, middleware application acts like a composition of functions)
11:14	justin_smith	domgetter: the general shape is (fn middleware-f [f] (fn [x] (post-process (f (pre-process x)))) - you can optionally pre-process x before f sees it, then you optionally post-process the result before it is returned
11:14	justin_smith	and you take f and return a new function with that pre/post processing
11:14	domgetter	okay. That all makes sense. I'll ruminate on that for a while, thank you
11:31	favetelinguis	not sure how to ask since i have limited understanding but im reading about piplines in core async and would like to do somethings like this "ch-in -> stateful-pipeline -> out, that is having the pipline remember what has been processed before, now my questions is if this is possible using only channels and transducers or if i have to put a stateful go-loop into the pipleine dealing with the state?
11:33	favetelinguis	then it would be like "ch-in -> ch-with-transducer1 -> go-loop with state -> some-more-transducer -> out-ch"
11:34	favetelinguis	my thinking is that if i need state i might just as well use a transducer in the go-loop instead of putting then on pipeline channels...
11:35	BRODUS	well transducers can be stateful
11:36	domgetter	(take 4) returns a stateful transducer: https://github.com/clojure/clojure/blob/clojure-1.7.0/src/clj/clojure/core.clj#L2738
11:37	domgetter	Do you have to use volatile! to do stateful transducing?
11:48	favetelinguis	found some slide about using volatile! to store state in transducers, should fit my needs, thanks
14:03	lokien	How to get every second element of a vector?
14:05	Bronsa	lokien: take-nth
14:05	lokien	Bronsa: thanks
14:56	lvh	domgetter: no, but it makes a lot of sense because it's more performant than many of the alternatives
14:57	lokien	How to take n first letters from a string? Is there a prettier way than (str (take n string))?
14:57	lvh	domgetter: a stateful transducer can do whatever it wants, including store some state in java/JS
14:57	lvh	lokien: you could try some string methods
14:57	lvh	there's also subs
14:57	lvh	lokien: (subs s start end)
14:58	lokien	lvh: clojure.string? nothing useful (or I can't search properly)
14:58	lvh	lokien: subs is in core
14:58	lokien	lvh: subs is a thing I was looking for, thank you
15:02	tuddman	I have http://clojure.org/cheatsheet bookmarked. has str functions. plus, well, everything else.
15:03	MJB47	there also this version: http://jafingerhut.github.io/cheatsheet/clojuredocs/cheatsheet-tiptip-no-cdocs-summary.html
15:03	MJB47	which has better search imo
15:03	MJB47	though ctrl-f is a thing
15:04	tdammers	ctrl-f is my bread and butter
15:04	tdammers	or rather, /
15:04	tdammers	unless a website chooses to break it
15:05	lokien	um, thanks
15:05	lokien	I'll bookmark it too
16:31	lokien	What can we do for large number readability? Something like 2_000_000
16:34	MJB47	if its only 0's
16:34	MJB47	then 2e6 is an option
16:36	lokien	what if it's not only 0's?
16:49	gfredericks	2e6 is bad since it gives you a float
16:50	gfredericks	I don't think there's anything basic for this
16:50	gfredericks	,(type 2e6)
16:50	clojurebot	java.lang.Double
16:55	ridcully	make it a const and never look at it again?
17:15	lokien	How to check if an item appears twice in a row in a string (or a seq)?
17:15	lokien	"somestring" -> false ; "someestring" -> true
17:18	justin_smith	,(some (partial apply =) ((comp (partial apply map list) (juxt identity rest)) "somestring"))
17:18	clojurebot	nil
17:18	justin_smith	,(some (partial apply =) ((comp (partial apply map list) (juxt identity rest)) "someestring"))
17:18	clojurebot	true
17:18	justin_smith	that probably isn't the best way to do it, but it was fun
17:19	MJB47	i was gonna use loop/recur
17:19	MJB47	idk whats simpler
17:19	lokien	uh, now I'll spend another 3 days trying to figure out how your function works, justin_smith
17:20	lokien	but thanks
17:20	gfredericks	,(defn repchar? [s] (->> s (partition 2 1) (some #(apply = %))))
17:20	clojurebot	#'sandbox/repchar?
17:20	gfredericks	,(repchar? "somestring")
17:20	clojurebot	nil
17:20	gfredericks	,(repchar? "someestring")
17:20	clojurebot	true
17:20	lokien	:o
17:20	lokien	justin_smith depositioned
17:21	justin_smith	gfredericks: wrote the same function, he just gave you the readable version
17:21	gfredericks	~justin_smith is the unreadable version of gfredericks
17:21	clojurebot	Ik begrijp
17:22	TMA	justin_smith: that's not certain. while yours is transparent, gfredericks' is somewhat opaque [at least or me]
17:22	MJB47	i find gfredericks much easier to read and understand
17:23	lokien	I find both of them confusing :^(
17:23	gfredericks	I find things in my pockets sometimes
17:23	lokien	lucky you
17:24	lokien	if they aren't snakes, of course
17:25	gfredericks	ugh pocket snakes are the worst
17:25	lokien	still better than NPEs, duh
17:26	gfredericks	NullPocketException
17:26	justin_smith	(try (frob x) (catch PocketSnake S ...))
17:29	lokien	I'm curious.. justin_smith, why do you only use one liners here? no defns, always anonymous functions
17:30	justin_smith	lokien: that is much simpler in irc
17:30	justin_smith	also, it's easier to put a one liner in a function, than it is to take one out of one
17:30	justin_smith	lokien: and also "one liner" - clojurebot only accepts a line at a time
17:30	lokien	justin_smith: much harder to put it into code
17:31	lokien	justin_smith: but you still could write them with defn
17:31	MJB47	i feel like that just adds uneeded bloat
17:31	justin_smith	exactly
17:31	MJB47	they are implicit when needed
17:32	justin_smith	why send two things to clojurebot when you can show what's needed with one
17:32	MJB47	everyone knows how defn works
17:32	MJB47	so why not
17:32	lokien	maybe it's easier to fit if one has more complex functions, my are like 10 lines or less
17:32	lokien	MJB47: I think you're right
17:45	justin_smith	also, clojurebot erases all def and defns once every 15 minutes or so, so using def / defn isn't reliable
17:49	TEttinger	down to under 256 characters, btw, if you just use this to generate a single name of some elder god or great old one or whatever
17:50	TEttinger	,(let[a #(apply str(flatten %))p partition R rand-nth n #(a(R(mapcat p[1 2 3]%&)))v #(n"aioeu""iaaiaa")](a[(n"STKNYPKLGVZ""GlThShNyFtCh""ZvrCthShrMycTch")(for[_" "][(v)(n"lpstnkgxzv"(concat[(R["h""gl""gr""nd"])(v)]"rnthggghtsltrkkhshng")"ghnlok")])]))
17:50	clojurebot	"Zerkiarn"
17:50	TEttinger	you were discussing illegibility?
17:52	TEttinger	ah, lokien left, but for strings I'd use (partial re-find #"(.)\1")
17:52	justin_smith	oh, good point
17:53	TEttinger	,((partial re-find #"(.)\1") "somestring")
17:53	clojurebot	nil
17:53	TEttinger	,((partial re-find #"(.)\1") "someestring")
17:53	clojurebot	["ee" "e"]
17:53	MJB47	if its only a string then yer thats the best way
17:53	MJB47	but he asked for seq as well iirc
17:53	TEttinger	surprised gfredericks, lord of the regex, didn't point that one out though
17:53	MJB47	oh i didnt read up
17:53	MJB47	my bad
17:57	TEttinger	,((partial reduce #(if (= %1 %2) (reduced true) %2)) "someestring")
17:57	clojurebot	true
17:57	TEttinger	,((partial reduce #(if (= %1 %2) (reduced true) %2)) "somestring")
17:57	clojurebot	\g
17:58	TEttinger	hm, should be nil then
17:58	justin_smith	,((comp true? (partial reduce #(if (= %1 %2) (reduced true) %2))) "somestring")
17:58	clojurebot	false
17:59	justin_smith	,((comp true? (partial reduce #(if (= %1 %2) (reduced true) %2))) "someestring")
17:59	clojurebot	true
17:59	TEttinger	,((comp not (partial reduce #(if (= %1 %2) (reduced nil) %2))) "someestring")
17:59	clojurebot	true
17:59	TEttinger	,((comp not (partial reduce #(if (= %1 %2) (reduced nil) %2))) "somestring")
17:59	clojurebot	false
18:00	TEttinger	the only case this fails is with justin_smith
18:00	TEttinger	the only case this fails is with justin_smith's and a collection that contains true, or mine and a collection that contains nil
18:01	TEttinger	mine also fails if the collection contains false
18:01	justin_smith	,((comp boolean #{::doubled} (partial reduce #(if (= %1 %2) (reduced ::doubled) %2))) "someestring")
18:01	clojurebot	true
18:02	justin_smith	instead of ::doubled you could use a gensym
18:06	ToBeReplaced	just a FYI to community; i haven't written clojure in about a year, i tried to add cider-nrepl 0.9.1 to my lein plugins, and there seems to be no way to start a REPL once i do that if i have :pedantic? :abort set
18:06	ToBeReplaced	this gives me a sour taste and makes me less likely to want to pick it up again commercially
18:07	ToBeReplaced	0.10.1 sorry
18:08	TEttinger	I don't use cider, lots of people in here do
18:09	TEttinger	justin_smith: there's a neat property here too. the collection can't contain itself as an element can it?
18:09	TEttinger	,(map (fn [coll] (= coll (reduce #(if (= %1 %2) (reduced coll) %2) coll))) ["someestring" "somestring"])
18:09	clojurebot	(true false)
18:09	ToBeReplaced	yeah, maybe the tech has moved and i should be looking at different tooling; the issue is they ask for different versions of org.clojure/tools.nrepl (and no way to exclude what lein asks for)
18:10	TEttinger	they?
18:10	TEttinger	cider?
18:10	clojurebot	cider is Cider is unstable and broken right now, most things don't work. Use the last stable version of nrepl.el for now.
18:10	TEttinger	haha
18:10	TEttinger	thanks clojurebot
18:10	TEttinger	not sure if that's still true
18:10	ToBeReplaced	haha, "they" referred to lein vs. cider-nrepl

19:11	tolstoy	ToBeReplaced: Did you resolve your issue? All I do is add tools.nrepl to the :dev profile and It Works.
19:51	ToBeReplaced	tolstoy: i did not resolve; is that true with :pedantic? :abort
19:52	tolstoy	Hm. I've never head of :pedantic?; Is that a lein thing?
19:52	tolstoy	I do run "lein deps :tree" all the time.
19:52	slester	not exactly clojure related, but just curious how you all come up with side projects to work on
19:53	slester	I've just been fiddling with 4clojure and advent of code and I can't really think up a good project to test my chops
19:53	ToBeReplaced	yes, it's a feature to puke when dependency ranges are detected
19:54	tolstoy	ToBeReplaced: I just added it to my project, and "lein deps :tree" still works. What does that key prevent?
19:54	tolstoy	ToBeReplaced: I actually never put stuff in ~/.lein/profiles.clj. I just keep it all in the project file. Maybe that's it?
19:54	ToBeReplaced	tolstoy: can confirm that adding tools.nrepl to :dev profile instead of :user profile makes a difference
19:55	tolstoy	Ah, good!
19:55	ToBeReplaced	if i add to :dev in the project.clj, it accepts; fails if i add to :user in a profiles.clj
19:55	ToBeReplaced	magic ;)
19:55	tolstoy	Is it possible to add a :dev profile to profiles.clj?
19:56	ianhedoesit	slester: I think a reasonable approach to start with is to just make things that already exist. thinking of truly unique and novel ideas isn't something that's easy (or something that everyone can do)
19:56	tolstoy	slester: For a long time, my side projects were side projects for work. Not sanctioned, just stuff it would be cool to use. In other words, that's where I found problems to solve.
19:57	slester	ianhedoesit, tolstoy, good advice!
19:57	ToBeReplaced	tolstoy: you can, yes... you're not meant to due to collisions
19:57	tolstoy	slester: Wouldn't it be cool to have drag/drop configuration for security scans? ;; That would get me into OM, etc.
19:58	tolstoy	ToBeReplaced: Ah. The reason I abandoned profiles.clj is that I wanted things to be explicit and for old projects to be self-consistent.
19:58	ToBeReplaced	it's a little weird because it should be in :user not :dev since it's meant to be for any project i work on... really i should just issue a PR to leiningen to update it's version of tools.nrepl
19:58	ToBeReplaced	yeah; i totally get that... better for repeatability of the dev environment if your whole team uses the same environment as well
19:58	tolstoy	ToBeReplaced: When working with others, no one cared because they didn't use Emacs, or didn't use the plugins (like lein ancient, etc). In other words, no impact on anyone else.
19:59	ToBeReplaced	makes sense
20:00	tolstoy	I figured that if anyone cared, I could just maintain a local project.clj and never commit it, or something.
20:00	tolstoy	ANYWAY, I think Cider is really good these days.
20:00	tolstoy	I really like the C-c C-p to pop-up an evaluation of an expression into a read-only buffer.
20:03	tolstoy	And I set the toggle so that buffer is pretty-printed.
20:04	tolstoy	Very light-tableish. ;)
