01:20	kenrestivo	is there any way to make networking code less... ugly? i wrote this but i hate it: https://www.refheap.com/112427
01:21	kenrestivo	it's for a component. it seems like a tangled unreadable mess. but i can't think of any other way to do it.
01:28	tolstoy	Hm. I wonder if Aleph's client libs would help.
01:28	kenrestivo	it might, though it has its own complexities
01:29	kenrestivo	my end goal here is a component that wraps mqtt in core.async
01:29	tolstoy	Are you working with activemq?
01:29	kenrestivo	mosquitto in this case
01:29	tolstoy	Oh, right. Okay
01:30	tolstoy	Hm. When I used to do this using actors, I'd have one actor that represented the connection, and another "linked" actor that was the supervisor.
01:30	tolstoy	When the connection actor threw an exception and died, the "link" mean that the supervisor actor got the message and could restart.
01:30	tolstoy	So, I wonder if you could do something similar?
01:31	kenrestivo	hmm, that might work.
01:31	tolstoy	On "go-loop" that manages the connection. If there's an error (.isConnect conn) or something, it drops a message in the "super" channel, then does.
01:31	tolstoy	The super channel just waits for that message and tries a reconnect.
01:32	kenrestivo	i like that, thanks.
01:33	tolstoy	Decomplects connection stuff from supervisor stuff? Gotta be some Clojury conference-circuit way of phrasing it.
01:34	tolstoy	mqtt seems kinda neat.
02:46	copycat	what does this look like? i'm not sure how to visualize this
02:46	copycat	(vec (map vector
02:46	copycat	(map + (range length) (repeat xpos))
02:46	copycat	(repeat ypos))))
03:03	visof	,(merge-with conj {:hello {:x 1 :y 3 :other [4 5 6]}} {:hello {:x 3 :y 1 :other [3]}})
03:03	clojurebot	{:hello {:x 3, :y 1, :other [3]}}
03:04	visof	how can i merge values of the same keys to a list
03:04	visof	to be {:hello {:x [1 3] :y [3 1] :other [[4 5 6] [3]]}} ?
03:04	TEttinger	,(merge-with list {:hello {:x 1 :y 3 :other [4 5 6]}} {:hello {:x 3 :y 1 :other [3]}})
03:04	clojurebot	{:hello ({:x 1, :y 3, :other [4 5 6]} {:x 3, :y 1, :other [3]})}
03:05	TEttinger	wait no that's awful :)
03:05	opqdonut	you need deep-merge-with
03:05	TEttinger	,(merge-with list {:hello {:x 1 :y 3 :other [4 5 6]}} {:hello {:x 3 :y 1 :other [3]}} {:hello {:x 2 :y 2 :other [1 5]}})
03:05	clojurebot	{:hello (({:x 1, :y 3, :other [4 5 6]} {:x 3, :y 1, :other [3]}) {:x 2, :y 2, :other [1 5]})}
03:06	TEttinger	that's why that's awful
03:06	opqdonut	yeah
03:07	visof	,(deep-merge-with conj {:hello {:x 1 :y 3 :other [4 5 6]}} {:hello {:x 3 :y 1 :other [3]}})
03:07	clojurebot	#error {\n :cause "Unable to resolve symbol: deep-merge-with in this context"\n :via\n [{:type clojure.lang.Compiler$CompilerException\n :message "java.lang.RuntimeException: Unable to resolve symbol: deep-merge-with in this context, compiling:(NO_SOURCE_PATH:0:0)"\n :at [clojure.lang.Compiler analyze "Compiler.java" 6704]}\n {:type java.lang.RuntimeException\n :message "Unable to resolve s...
03:07	visof	is it at other lib
03:07	opqdonut	I don't know
03:07	opqdonut	I've defined it myself
03:08	opqdonut	might be in some library with some other name
03:08	opqdonut	but conj is wrong anyway
03:08	opqdonut	or it's ok if you get the empty sequences from somewhere
03:08	opqdonut	e.g. like this:
03:09	opqdonut	,(merge-with conj {:x [] :y []} {:x 1} {:x 2 :y 3} {:x 3 :y 4})
03:09	clojurebot	{:x [1 2 3], :y [3 4]}
03:09	visof	opqdonut: ah ok
04:04	dxtr_	hi
04:05	dxtr_	is "the joy of clojure" still up to date? or should i be looking at some other book to get started?
04:11	ARM9	it's still mostly up to date, it probably still recommends that "use" be used instead of recommending require
04:16	tolstoy	On a recent podcast, Stuart Holloway mentioned that all the code in his pre-1.0 Clojure book still runs.
04:17	tdammers	as in, he fired up a repl and loaded the code, and that repl is still running?
04:24	Glenjamin	joy of clojure 2nd edition is less than a year old i think
10:35	njorth	gp /st
10:48	ToxicFrog	So, here's a question I haven't needed to ask in ages, such that I've forgotten the answer
10:48	ToxicFrog	What's the easiest way to just write a one-off .clj script and shebang it?
10:49	ToxicFrog	lein doesn't seem to have a "lein run-script" command
10:52	tdammers	not usually viable, startup time tends to be prohibitive for this kind of thing
11:02	schmir	ToxicFrog: https://github.com/boot-clj/boot/wiki/Scripts
11:03	ToxicFrog	schmir: that's specific to having the Boot tool installed
11:04	ToxicFrog	It looks like the answer I actually want is: exec java -cp ~/.m2/repository/org/clojure/clojure/$VER/clojure-$VER.jar clojure.main "$@"
11:04	ToxicFrog	And then stuff that in a script I can put in the #!
11:05	ToxicFrog	tdammers: it turns out that when not using lein, startup time is dramatically reduced
11:05	ToxicFrog	Still not something I'd want to use with, say, find -exec, but Good Enough for some things.
11:10	ToxicFrog	Sigh.
11:11	ToxicFrog	"java.lang.Boolean cannot be cast to clojure.lang.Symbol, compiling:(.../2.clj:1:1)"
11:11	ToxicFrog	The first four lines of this file are comments.
11:15	ToxicFrog	Hmm.
11:15	ToxicFrog	(repeatedly read-line) looks like a good way to get a line-seq from in, since you can't just (line-seq in)
11:15	ToxicFrog	But it NPEs on EOF.
13:20	visof	hi guys
13:26	visof	i code method which take some time, but i want to make it processed in the background and then run another fast code, i make this (do (future (long-time-method)) (short-time-method))
13:26	visof	and i still get longer time
13:27	visof	i just wnat long-time-method run in background and skip to short-time-method
13:27	rhg135	There is overhead, but how much longer?
13:34	visof	rhg135: what do you mean with how much longer?
13:35	beaky	i have crap shoulders, tspine, and squat mobiltiy
13:35	beaky	oops wrong channel
13:37	rhg135	visof: spinning up a thread incurs overhead from scheduling. Usually it should just be a few ms per thread. Also your code seems correct.
13:39	visof	rhg135: is there a method to do this in a more efficient way, what if my long-time-method take 1 min, i and don't want the user wait this time
13:42	justin_smith	visof: the do block takes the amount of time to dispatch the future, plus the time of short-time-method - the run time of long-time-method will not affect it unless long-time-method is heavy enough to lock up basically your whole computer
13:42	rhg135	It depends. In languages without threads you would use callbacks
13:43	rhg135	But that's not a good fit sometimes
13:44	justin_smith	callbacks are about coordination, not processing - a callback might run on a different thread, it might run on the same thread
13:47	rhg135	justin_smith: I'm assuming callbacks being independent from threads here
13:48	rhg135	In practice, not usually
13:51	rhg135	Oh right. Yes, justin_smith is correct. I don't know what I'm thinking
13:52	rhg135	You can't do parallel execution on the jvm without threads
13:53	justin_smith	callbacks are good if you don't have threads and still have things that need to be done concurrently, or if you need to let some other part of the system have the control of the timing or conditional execution of your code
13:55	rhg135	They're great except for the inversion of control
14:44	fuddu-coder	i have a collection of java objects. what would be the best way to figure out distinct objects in the collection based on certain fields
14:44	fuddu-coder	the fields would be extracted through interop ofcourse
14:45	fuddu-coder	,(+3 4)
14:45	clojurebot	#error {\n :cause "java.lang.Long cannot be cast to clojure.lang.IFn"\n :via\n [{:type java.lang.ClassCastException\n :message "java.lang.Long cannot be cast to clojure.lang.IFn"\n :at [sandbox$eval25 invokeStatic "NO_SOURCE_FILE" 0]}]\n :trace\n [[sandbox$eval25 invokeStatic "NO_SOURCE_FILE" 0]\n [sandbox$eval25 invoke "NO_SOURCE_FILE" -1]\n [clojure.lang.Compiler eval "Compiler.java" 6943]...
14:45	justin_smith	fuddu-coder: maybe something like (group-by #(.foo %) objects)
14:45	ridcully	,(+ 3 4)
14:45	clojurebot	7
14:47	fuddu-coder	justin_smith: true. but i would liek to have a combination of fields determine the distinctness. does that make sense
14:47	fuddu-coder	*like
14:47	justin_smith	fuddu-coder: hmm so would you want one map where you look up based on the set of fields they have, or one grouped map for each field, or?
14:48	fuddu-coder	one map where you look up based on the set of fields they have
14:48	ridcully	or type
14:49	justin_smith	so make set-of-fields - a function that takes an object and returns a set of relevant fields
14:49	ridcully	could you elaborate on what the differences are there?
14:49	justin_smith	then group-by set-of-fields
14:50	fuddu-coder	yup. that would be one way to go.
14:52	sdegutis	Clojure's first commit: https://github.com/clojure/clojure/commit/894a0c81075b8f4b64b7f890ab0c8522a7a9986a
14:52	justin_smith	fuddu-coder: seems the simplest thing - then you could derive "all objects with field X" by filtering the keys for that field and merging all vals the keys match
14:54	ARM9	sdegutis humble beginnings
15:08	sdegutis	ARM9: aint it ho
15:08	sdegutis	*tho
15:09	TimMc	In the beginning there was a cons cell, a symbol, and scope.
15:13	sdegutis	And a single namespace?
15:14	sdegutis	Can someone ELI5 Rich's hair? https://github.com/richhickey
15:14	sdegutis	is that a NY thing or something?
15:15	ARM9	looks ready to party like it's 1984
15:17	TimMc	There is no need to explain. His hair is amazing and that is all.
15:19	TimMc	He probably takes the same appoach to fashion I do: Pick a style and let it come around again and again. :-D
15:36	sdegutis	TimMc: haha that's too much work
15:36	clojurebot	Huh?
15:36	sdegutis	TimMc: my approach is to just shave my head every 2 weeks; never have to worry about styling it, and shampooing it is way easy&quick
15:37	sdegutis	plus its not too hot in the summer this way; and in the winter i can just wear a hat. done.
15:39	TimMc	Oh, I meant overall style, not just hair... but I keep my hair in a ponytail for a similar reason. Very little work.
15:39	sdegutis	oh
15:39	sdegutis	haha yeah
15:39	sdegutis	nice
15:40	TimMc	But really I find very little profit to be had in analyzing people's appearance...
15:43	TimMc	However, I will criticize the heck out of his use of whitespace.
15:45	amalloy	"use" is a strong word. reading compiler.java it sometimes seems like his keyboard is just on the fritz
15:46	Bronsa	it's just postmodern indentation
15:47	TimMc	I wonder if that's what happens when you try to write Java in emacs without good indentiation settings and you're just fighting the mode the whole time.
15:47	Bronsa	TimMc: more likely it's what happens when you switch editors and IDEs
15:52	justin_smith	Whitesmiths style https://en.wikipedia.org/wiki/Indent_style#Whitesmiths_style
15:54	ecmike	no likey
15:55	ecmike	Allman is ok though
15:55	justin_smith	that wiki page "lisp" style example is wrong in at least two ways - lisp indent applied to algol lang, and hanging open brace
15:55	TEttinger	huh, Allman is what I use. never knew the name
15:56	justin_smith	many GNU projects use K&R
15:56	ecmike	I get annoyed with lines that are purely syntax symbols though, it's unnecessary cognitive noise
16:11	OrbitalKitten	hey guys, is there a reason why \ evaluates to \newline when used 'naked' in the repl and seems to evaluate to a space when used in a function (eg. (str "Hello" \ "World"))?
16:15	amalloy	because the character you typed after the \ in your repl was a newline
16:15	TimMc	OrbitalKitten: You had to hit newline twice in order to enter it in the REPL, yeah?
16:15	TimMc	It can take either a literal like \™ or a code like \space and what you gave it was a literal newline. :-)
16:15	OrbitalKitten	not sure
16:15	pbx	OrbitalKitten, also at end-of-line in the REPL it's the line contunuation character
16:15	OrbitalKitten	oh
16:16	OrbitalKitten	I get it
16:16	TimMc	(To be clear, \newline is a much better idea.)
16:16	pbx	nevermind what i just said about line continuation, that looks to be false :\
16:16	OrbitalKitten	I will test that in the terminal, maybe it's cider doing weird things.
16:17	OrbitalKitten	Hmm, my bad, cider inserts the newline automatically, I indeed had to tap entre twice
16:50	fuddu-coder	noob here. can i pass multiple functions to a map . is so which one among this can help me
16:50	fuddu-coder	http://clojuredocs.org/clojure.core/map
16:52	beaky	,(map (juxt inc dec) [0])
16:52	clojurebot	([1 -1])
16:53	fuddu-coder	yo.. thx.. juxt can help me. cool
16:53	beaky	,(map (juxt inc dec) [0 1 2 3])
16:53	clojurebot	([1 -1] [2 0] [3 1] [4 2])
16:53	beaky	,(map (juxt inc dec id) [0 1 2 3])
16:53	clojurebot	#error {\n :cause "Unable to resolve symbol: id in this context"\n :via\n [{:type clojure.lang.Compiler$CompilerException\n :message "java.lang.RuntimeException: Unable to resolve symbol: id in this context, compiling:(NO_SOURCE_PATH:0:0)"\n :at [clojure.lang.Compiler analyze "Compiler.java" 6704]}\n {:type java.lang.RuntimeException\n :message "Unable to resolve symbol: id in this context"...

16:53	beaky	:D
16:55	WorldsEndless	I can convert .docx to pdf on disk, and I can merge pdf on disk. But I'm trying to take the "on disk" part out of the equation and go straight from my mongodb -> docx -> pdf -> merged pdf -> to client. Anyone have experience with something like this?
16:55	WorldsEndless	My java stream-fu is a little weak, and it's tripping me up
16:56	justin_smith	WorldsEndless: you can cheat on linux with an in-memory filesystem mounted on tmp
16:56	justin_smith	WorldsEndless: what are the requisite classes for the methods?
16:56	justin_smith	sometimes bad APIs force you to use files, and then you are stuck
16:57	WorldsEndless	I'm using org.docx4j for the doc manipulation, and org.apache.pdfbox for the PDF stuff, and some don't have javadocs to help out...
17:00	amalloy	justin_smith: not necessarily stuck, if they only read/write the files sequentially; you can use a named pipe then
17:01	WorldsEndless	I'm able to write straight from mongo to a client using a clojure.java.io/piped-input-stream (which seems obnoxiously difficult to find docs for)
17:01	WorldsEndless	But in that case I'm missing both the to-PDF and the merge-PDF steps
17:07	TimMc	justin_smith: I use a ramdisk to speed up clojure compilation. :-D
17:25	sdegutis	Hi
17:31	m1dnight_	How hard would it be to implement a lein plugin that searches for unused imports/uses?
17:31	m1dnight_	I need a new pet project and that comes to mind. Ive discussed here a while back.
17:33	beaky	its probably easy
17:34	amalloy	m1dnight_: long ago technomancy did that with slamhound. if you were going to revive the project you'd probably use tools.analyzer
17:36	m1dnight_	Oh, I have the git right here.
17:36	m1dnight_	Lets see how hard this will be :>
17:36	TimMc	eastwood, I think
17:37	m1dnight_	Oh, eastwood does that?
17:37	m1dnight_	Darnit
17:37	m1dnight_	Late to the party :>

17:46	TEttinger	why quote?
17:46	visof	MJB47: thanks

18:21	WorldsEndless	oops. I had the wrong ns
18:21	WorldsEndless	It's in ring...
18:21	WorldsEndless	Which would be why I've been struggling to fidn the docs
18:21	justin_smith	that would explain not finding the docs
18:22	justin_smith	more evidence that use shouldn't be used
18:22	WorldsEndless	Ha :) I wasn't using "use" but had it as io/piped-input-string and hadn't looked at the ns declaration recently enough to see that io in this file wasn't io as I have it in other files

18:32	clojurebot	#'sandbox/op
18:32	justin_smith	,(mm op)
18:32	clojurebot	#<ClassCastException java.lang.ClassCastException: clojure.lang.Var cannot be cast to clojure.lang.Named>
18:32	justin_smith	:P
18:34	justin_smith	,(defn mm [vars] (map (comp :name meta) vars))
18:34	clojurebot	#'sandbox/mm
18:34	justin_smith	,(mm op)
18:34	clojurebot	(+ -)
18:34	justin_smith	but that only works with the vars, not the functions - functions don't have names
19:34	didibus	Can I create a null from Clojure?
19:34	justin_smith	,nil
19:34	clojurebot	nil
19:34	superstructor	nil has the same value as Java null
19:35	didibus	Hum
19:35	didibus	I call (str "null:" nullObj)
19:35	didibus	And I get aNullPointerException
19:35	didibus	but if I do ,(str "null: " nil)
19:35	didibus	it works
19:35	didibus	,(str "null: " nil)
19:35	clojurebot	"null: "
19:36	amalloy	mmmmm, that's possible only because nullObj is not in fact nil
19:36	amalloy	rather it's some sort of lazy thing that realizes itself when you try to print it, and the thing it was lazily putting off doing causes an exception
19:36	justin_smith	didibus: is the object null? what if it has a toString that is getting the NPE?
19:36	didibus	oh, actually, I thought it would print nil, but it prints blank, so it's probably something later on that throws the null pointer
19:37	justin_smith	,(pr-str nil)
19:37	clojurebot	"nil"
19:37	justin_smith	if you want a less ambiguous printout
19:37	didibus	Oh cool, is that in core?
19:37	justin_smith	yes
19:37	justin_smith	see also prn, pr
19:41	didibus	oh, that does'nt help me because (str) actually does not concatenate the nil
19:41	justin_smith	didibus: you would use pr-str instead of str
19:41	didibus	Ohhhhhhhhhhhhh
19:41	justin_smith	or inside it
19:41	didibus	lol, ok thanks, makes much more sense now
19:42	justin_smith	,(pr-str "OK: " nil)
19:42	clojurebot	"\"OK: \" nil"
19:42	justin_smith	,(str "OK: " (pr-str nil))
19:42	clojurebot	"OK: nil"
19:43	didibus	Clojure just really has a function for everything lol
20:23	ecmike	,(pr-str "null: " nil)
20:23	clojurebot	"\"null: \" nil"
20:24	ecmike	ah, haha
20:24	ecmike	,(pr-str 1 2 'a)
20:24	clojurebot	"1 2 a"
20:39	copycat	what kind of error is this?
20:40	copycat	No protocol method ReadPort.take! defined for type object: [object Object]
20:41	copycat	not much results on google so... =(
21:13	WickedShell	copycat, I'm assuming that thats from trying to use core.async reading from a channel? (If so I suspect its because the object passed isn't a channel).
21:13	copycat	yes, i found the bug. forgot to add in a function to return the channel =)
23:59	dongcarl	clojure newbie here, in this snippet: "loop [stack (:stack state), delims ""]", the comma serves to seperate the two bindings and nothing else right?
23:59	justin_smith	dongcarl: commas are whitespace
