#clojure – 2014-11-25

00:06	kenrestivo	ah, the dark dot is use/used, the pale dot is transitively use/used
00:07	kenrestivo	if the code is on github, i should submit a patch that shows that as a mouseover on those circles
00:07	bbloom_	do any former common-lispers know enough about how CL implementations handle line numbers? i'm curious where/how they store line numbers for stack traces w/o general purpose clojure-like metadata
00:08	kenrestivo	speaking of stacktraces, here's what youtube is showing: https://www.refheap.com/93921
00:08	kenrestivo	it's not base64, apparently
00:09	bbloom_	could be url-safe base64
00:09	bbloom_	probably encrypted :-P
00:09	ggreer	they just changed + and / to - and _
00:09	ggreer	and yes, it's encrypted
00:20	bbloom_	as best i can tell, line numbers are calculated from "code-location" on the "compiled-frame" structs -- seems that that's calculated from the program counter in the compiled code output, such that only compiled forms get line numbers
00:21	bbloom_	i guess if you eval some definition later, you either won't get a line number or it will be the location of the eval, not the place that produced the forms, since the objects themselves can't have metadata really
00:21	bbloom_	interesting....
00:21	bbloom_	sorry, i meant to add: that's in SBCL
00:22	bbloom_	which google suggested has line numbers in backtraces, unlike many other CL impls :-)
04:13	agumonkhost	cglv: the issue with remote lein repl was that by default lein listens to 127.0.0.1, so one needs to lein repl :host 0.0.0.0 :port ... to enable remoting
04:13	rritoch	Does clojure.core/require automatically reload sources if the source code has been modified since it was last loaded (clojur.core/load)?
04:14	SagiCZ1	rritoch: no, you have to call require again
04:14	SagiCZ1	or otherwise reload the file using your repl tools
04:15	agumonkhost	cglv: pretty much 'duh' but alas. this was offered to me by the RTFM association.
04:15	rritoch	SagiCZ1: But every time you call require it checks if the file has been modified?
04:17	rritoch	SagiCZ1: Currently I'm using ns-find & load to load namespaces in this particular case, but I'm looking for the easiest solution to reload if the file has been modified since it was last loaded.
04:18	ucb	it seems like cider comes with a set of keybindings for reloading namespaces and their dependencies
04:18	ucb	I've pressed them by chance (trying to switch buffers, etc.) but never really found what they are
04:18	ucb	anybody knows what they are? ^_^
04:21	rritoch	SagiCZ1: Ex. (if (not (find-ns 'my.namespace)) (load "my.namespace")) but I'm looking for something that will also re-load the namespace if the sources have been modified since it was last loaded.
04:25	SagiCZ1	rritoch: i see, i am not sure how to do that from the program itself, but other people might know
04:32	mavbozo	e
04:41	agumonkhost	hey back
04:42	agumonkhost	with this project.clj http://pastebin.com/y4wCxqk0 , lein deps fetching core.async (found in ~/.m2/*), yet (require '[core.async ...]) fails with "FileNotFoundException Could not locate core/async__init.class or core/async.clj on classpath ..."
04:46	clgv	agumonkhost: the full namespace is "clojure.core.async" right?
04:46	clgv	yeah it is, I checked
04:47	agumonkhost	hi clgv IIRC I tried both, time to try again
04:54	agumonkhost	clgv: ok, wrong path for running lein, thus no deps, thus no async
04:54	agumonkhost	thanks
04:55	clgv	yeah you must be within the project ;)
05:10	agumonkhost	clgv: I'm ashamed of my own nooberie here
05:10	clgv	agumonkhost: no problem, now you will remember it better ;)
06:13	the_frey	has anybody used the JavaMail mboxstore in a clojure project?
06:19	clgv	how do I specify which protocols jetty can use and must not use? is there an option in "ring"?
06:20	weavejester	clgv: By default the Jetty adapter will just use HTTP unless you supply a keystore
06:20	clgv	weavejester: yeah, I already have it running HTTPS
06:20	weavejester	clgv: I tend to use nginx to handle SSL, however.
06:20	clgv	weavejester: that is not an option in that scenario.
06:21	weavejester	clgv: If you have it running HTTPS, I'm not sure I understand your question.
06:21	clgv	weavejester: I want to configure which protocols are allowed, e.g. forbid SSLv3 and previous versions
06:22	weavejester	clgv: Oh I see
06:22	weavejester	clgv: That might require some Jetty black magic :)
06:23	clgv	weavejester: ok, I gotta check the jetty api
06:23	weavejester	clgv: 'fraid so
07:00	ordnungswidrig	clgv. http://wiki.eclipse.org/Jetty/Howto/Configure_SSL is pretty complete, I think
07:01	clgv	ordnungswidrig: thanks :)
07:02	clgv	ordnungswidrig: though I need to configure it via API for my embedded jetty
07:03	ordnungswidrig	The XML maps directly to the API, IIRC
07:03	ordnungswidrig	In the beginning jetty could only be configured by the API
07:08	pandeiro	if i have portions of my project.clj that are repeated in different sections, can i (def repeated-part [...]) and then reference that instead of repeating the vector in different places?
07:10	hellofunk	does core.logic recognize basic math as part of unification for doing things like solving a system of equations?
07:13	ordnungswidrig	pandeiro: you can do this with profiles to some extend
07:14	pandeiro	ordnungswidrig: stick it in a profile, then make an alias that uses that profile to do some task? that sort of thing?
07:16	ordnungswidrig	more like thath: https://github.com/technomancy/leiningen/blob/master/doc/PROFILES.md#composite-profiles
07:19	pandeiro	ordnungswidrig: ok thanks
07:38	SagiCZ1	~lazy-logs
07:38	clojurebot	lazy-logs is http://logs.lazybot.org/
08:54	skratl0x1	I have a macro that takes a vector, I want to pass this vector to a function during macro expansion time, but it contains forms that need to be evaluated, how do I do that?
08:57	gfredericks	skratl0x1: actual examples would be helpful here
08:59	ordnungswidrig	skratl0x1: you cannot expand the forms during macro expansion, at that time it's only lists of lists and symbols
09:00	skratl0x1	no eval?
09:01	gfredericks	you can technically call eval but that has all sorts of edge cases and is not how macros are meant to work
09:03	hyPiRion	fear no eval
09:07	llasram	Premature optimization is the root of all eval
09:09	sqd	any idea why my usage of [serial-port “1.1.2”] with (serial/on-byte port f true) gets messages with a delay, compared to using the built-in serial monitor from the arduino IDE?
09:10	Jker	someone here is a programmer ?
09:10	ToxicFrog	Jker: I suspect most are.
09:11	Jker	who is ?
09:11	sqd	or: is there a recommended way to get notified of the last byte read from a serial port?
09:12	Jker	someone here is a unity 3d programmer ?
09:34	edw	Is there any way to get the this of a function? I'd like to be able to write a function that accesses its own metadata.
09:35	hyPiRion	,(^:foo (fn f [] (meta f))) ; <-- edw
09:35	clojurebot	{:foo true}
09:35	edw	Ah! Duh. Thanks!
09:54	visof	hi guys
09:54	visof	,(into {} [{:a {:hello :World}} {:a {}}])
09:54	clojurebot	{:a {}}
09:54	visof	,(into {} [{:a {}} {:a {:hello :World}}])
09:54	clojurebot	{:a {:hello :World}}
09:54	gfredericks	oh geez
09:54	visof	how can i get the same last effect for all situation?
09:54	jeremyheiler	,(-> {} (assoc :a 1) (assoc : b))
09:54	clojurebot	#<RuntimeException java.lang.RuntimeException: Invalid token: :>
09:55	jeremyheiler	,(-> {} (assoc :a 1) (assoc :b 2))
09:55	clojurebot	{:b 2, :a 1}
09:55	jeremyheiler	ah
09:55	gfredericks	,(reduce into {} [{:a {:hello :World}} {:a {}}])
09:55	clojurebot	{:a {}}
09:55	jeremyheiler	nvm
09:55	visof	gfredericks: the values gone
09:55	gfredericks	oh um
09:55	gfredericks	visof: the logic here is not clear
09:56	jeremyheiler	visof: my point is that the last one wins because it's like your associating a new value of the old
09:56	clrnd	he wants to keep "truthy" values in a dict
09:56	gfredericks	{} is truthy
09:56	clrnd	then he is just confused :P
09:56	gfredericks	,(apply merge-with merge [{:a {:hello :World}} {:a {}}])
09:56	clojurebot	{:a {:hello :World}}
09:56	clrnd	sorry I thought this was #javascript
09:57	gfredericks	visof: is maybe that ^ what you're going for?
09:57	gfredericks	,(apply merge-with merge [{:a {:hello :World}} {:a {:other :entries}}])
09:57	clojurebot	{:a {:other :entries, :hello :World}}
09:57	gfredericks	has ^ that behavior
09:57	visof	,(apply merge-with merge [{:a {:hello :World}} {:a {}} {:a {:clojure :nice}}])
09:57	clojurebot	{:a {:clojure :nice, :hello :World}}
09:57	visof	gfredericks: great, thanks!
09:58	gfredericks	np
11:00	crash_ep	opinion question: should a transducer serve purely as a transformation of its inputs, or is it idiomatic for a transducer to have externally-visible side effects?
11:00	crash_ep	(note I am not talking about the inherent statefulness of certain kinds of transducers, like `partition`)
11:02	clrnd	that's almost a philosophical question, but I'd argue that they should be pure
11:04	clgv	crash_ep: transducers are intended for channels as well, or does that not count as side effect?
11:05	crash_ep	clgv: that's the use case I am asking after. Should I write a transducer that can "do something" to the values that are sent through a channel? Or are transducers intended purely for stream transformations.
11:06	crash_ep	an example of a side-effecting transducer like the one I am asking about is in this blog post: http://www.martinklepsch.org/posts/using-coreasync-and-transducers-for-direct-s3-upload.html
11:06	crash_ep	which does an excellent job of explaining how to use transducers. I'm just curious because it's the first time I've seen them used this way.
11:07	clgv	crash_ep: the transducer write-ups and videos usually name channels as another scenario where the general functionality defined via a transducer is useful
11:07	clgv	so you can have eager, lazy and channel ops with the same transducer definition
11:09	crash_ep	clgv: I may be misunderstanding what you are saying, but that sounds orthogonal to what I'm after? :)
11:19	clgv	crash_ep: I am not entirely sure what you are after ;)
11:21	crash_ep	clgv: imagine I create a transducer using this code: (map #(write-to-file my-file %))
11:21	crash_ep	clgv: and then I give that transducer to a channel that delivers strings or input streams
11:22	crash_ep	clgv: That would result in writing the strings or input streams to my-file every time the channel delivers a new value.
11:22	l1x_	hi
11:22	crash_ep	clgv: but is that the intended use case for transducers?
11:23	l1x	what is the best way to send data for processing to async/threads ?
11:24	l1x	i was thinking either have 1 channel across everything and threads are listening to their on thread-name or have N channels one for each thread
11:25	justin_smith	l1x: why do you care which thread takes your task? why not just let them all listen to the same channel
11:26	l1x	hmm ok
11:26	justin_smith	and you can't listen to a channel but only take certain messages, core.async does not work that way
11:26	l1x	no selective receive? :)
11:26	justin_smith	no, not an option
11:26	l1x	ok
11:27	l1x	how do i make sure my "producer" does not overload the channel?
11:27	l1x	aka how do you do flow control
11:27	justin_smith	l1x: by making a channel with no buffer
11:27	teslanick	justin_smith: doesn't filter work like that? Pipe a channel through a filter (getting a new channel), messages that obey the filter are drained from the input channel.
11:28	l1x	justin_smith: and what happens than?
11:28	justin_smith	teslanick: and other messages stay on the channel? or do they get discarded?
11:28	l1x	the write waits for the read?
11:28	teslanick	justin_smith: True, you'd need a 'blowoff valve' to pull messages that don't match the filter off the input channel.
11:29	justin_smith	teslanick: yeah, my point is - you take all the channel gives you if you take at all, and it is your job to decide how to handle things that "aren't for you" - or you only read channels that are for you
11:30	justin_smith	l1x: yeah, the channel will block the message coming on if it isn't buffered
11:30	stuartsierra	There's also pub/sub, which lets you do some filtering.
11:30	teslanick	Understood. So if you need a subset of a channel "just for you", you want to use a topic-based chan
11:30	l1x	ohh
11:30	teslanick	Yeah, a pub/sub
11:30	l1x	justin_smith: thanks!! this is really useful
11:30	l1x	i wish there was better doc around core/async
11:31	teslanick	BTW, I've found these two pieces very useful for the not-well-documented features of core.async
11:31	teslanick	http://yobriefca.se/blog/2014/06/04/publish-and-subscribe-with-core-dot-asyncs-pub-and-sub/
11:31	teslanick	http://yobriefca.se/blog/2014/06/01/combining-and-controlling-channels-with-core-dot-asyncs-merge-and-mix/
11:31	justin_smith	teslanick: stuartsierra: right, but that's a whole other can of worms, because then everybody sees all the published contents
11:31	daniel___	everytime anyone says teslanick, my irssi lights up
11:31	justin_smith	modulo the filtering and topics of course
11:32	teslanick	daniel___ ??
11:32	lazybot	teslanick: What are you, crazy? Of course not!
11:32	teslanick	lazybot: quiet you.
11:32	justin_smith	lazybot - can you even help it??
11:32	lazybot	justin_smith: Definitely not.
11:34	teslanick	justin_smith: Do you mean that you can "duplicate" messages by subbing multiple channels to the same topic?
11:35	justin_smith	right - if your logic is "which listener gets each of these messages on onechannel" then you need all your filters on your subscribers to be mutually consistent, or you get messages acted on twice or more, or dropped
11:36	justin_smith	so the real fix is - read a channel, act on every message you get. And design other things around that.
11:36	teslanick	(aside, "duplicate" as a verb is an awkward word)
11:37	justin_smith	so, as I initially suggested, if you want threads working on tasks in parallel, put all tasks on one channel, and have all threads listening to that channel, each message will go to a thread that is ready
11:37	justin_smith	much simpler
11:40	l1x	justin_smith: and when the "consumer" reads the queue it blocks it too
11:40	l1x	right?
11:40	l1x	so I could have N threads with while true; read queue
11:41	l1x	or there is a more idiomatic way to do that?
11:41	l1x	teslanick: thanks!
11:41	daniel___	there it goes again
11:43	justin_smith	l1x: yeah, if all threads are doing the same thing, just have each one reading from the same channel and executing on what they get, in a loop
11:44	justin_smith	if they do different things, give them each a channel, and decide which channel to put onto based on what you want done
11:45	d0ky	hello how can i achieve that when i insert into hash-map new hash-map item: (into path new-path) i need to have new-path to be the last item in path ... i know that vector would do the job but hash-map suitable for working with it , thanks for any help
11:45	justin_smith	d0ky: hash-maps are not ordered
11:46	d0ky	so the only way is to use vector ?
11:46	justin_smith	or a sorted-map, but that is sorted by key and sort function, not insertion order
11:46	l1x	justin_smith: thanks, this is very helpful
11:47	Glenjamin	https://github.com/amalloy/ordered would work
11:47	Bronsa	there is an ordered map somewhere
11:47	Bronsa	^ there
11:47	justin_smith	I don't know if there is anything off the shelf that respects insertion order, and also allows ~constant time lookup
11:47	justin_smith	oh, nice!
11:47	Glenjamin	ordered just wraps a map + vector together
11:47	justin_smith	(inc Glenjamin)
11:47	lazybot	⇒ 10
11:47	justin_smith	makes sense :)
11:48	d0ky	Glenjamin: justin_smith: thanks you both
11:49	cityspirit	anyone have any strong opinions on korma vs yesql?
11:50	clgv	crash_ep: sounds totally reasonable
11:51	justin_smith	cityspirit: korma is semi-abandoned at this point, right?
11:51	justin_smith	also, I like yesql because sql is already a good dsl for doing sql :)
11:53	mikos	yesql is ace
11:53	mikos	did i read somewhere that it will support passing a hashmap soon?
11:53	cityspirit	justin_smith: is it? I wasn't aware. I like yesql a little better too, but with yesql you'd probably want to integrate like c3p0 on your own right?
11:54	justin_smith	cityspirit: that's fairly easy actually, but yeah.
11:55	justin_smith	cityspirit: callen/bitemyapp, who was the last really active maintainer of korma I know of, kind of hates Clojure now. But I don't follow korma closely so there well may be more going on than I know of.
11:56	mikerod	Does leiningen have some "default" repositories it looks in for artifacts?
11:56	mikerod	e.g. If I have a :plugins dependency, I have noticed it is fetched without me specifying any :repositories
11:57	technomancy	mikerod: sure; clojars and central
11:57	justin_smith	cityspirit: and regarding c3p0, the way to do that with yesql is to provide a :datasource key in your db-spec, which has the c3p0 object in it. There are interop libs, but it is straightforward enough to use the class directly.
11:57	mikerod	technomancy: I figured that was the case. I was just curious what the defaults were.
11:57	cityspirit	justin_smith: great, thanks for the info. I'll give that a whirl
11:58	mikerod	I suppose leiningen has some tool to show the "effective" project configuration map for a given project?
11:58	mikerod	Similar to the idea of the "effective pom" in Maven
11:58	mikerod	this is a better google question
11:59	technomancy	mikerod: check out the lein-pprint plugin
11:59	justin_smith	cityspirit: you may want org.tobereplaced.jdbc-pool - that makes it really easy
11:59	technomancy	`lein pprint :repositories`
11:59	justin_smith	cityspirit: but if you look at the lib, it also doesn't have a lot of meat to it :)
12:00	mikerod	technomancy: thanks for the info. I'll check that out.
12:00	justin_smith	cityspirit: very simple https://github.com/ToBeReplaced/jdbc-pool/blob/master/src/org/tobereplaced/jdbc_pool.clj
12:01	crash_ep	clgv: thanks!
12:04	sdegutis	weavejester: sorry to bother you by being over-playful about your secret project
12:05	sdegutis	weavejester: anyway we guessed it's some sort of Clojure code reformatter
12:05	weavejester	sdegutis: It's not really secret, just not ready for release, and it is indeed a Clojure code formatter.
12:05	weavejester	I wanted something like gofmt
12:06	sdegutis	Who is the intended audience?
12:06	cityspirit	justin_smith: thanks! I might just use that as example code to work off of
12:06	justin_smith	weavejester: awesome idea, I look forward to trying it when it is ready
12:06	weavejester	sdegutis: Me ;)
12:06	sdegutis	I personally just do C-x h M-q TAB
12:06	weavejester	sdegutis: Or anyone who happens to need a Clojure formatter.
12:06	justin_smith	cityspirit: he is using some macro magic to derive setter methods for map keys
12:06	justin_smith	sdegutis: that won't insert line breaks
12:07	sdegutis	justin_smith: true
12:07	weavejester	sdegutis: Sure, but that won't work with CI
12:07	sdegutis	weavejester: true
12:07	Glenjamin	the problem's i've had with formatters are mostly deciding when to line break, and with-* style methods that don't start with with-
12:07	weavejester	I want to be able to say: lein clofor :check
12:07	justin_smith	weavejester: technically you can script with emacs - but who wants command line emacs in their CI
12:07	weavejester	And then for it to fail CI if the code isn't formatted right
12:07	Glenjamin	so if you can solve those two, great job :D
12:08	weavejester	justin_smith: Yeah, but the clojure-mode indenter isn't really intended as a full code reformatter
12:08	justin_smith	right
12:08	justin_smith	so that's the real issue - it won't do smart line breaks, etc.
12:08	weavejester	Yep. I want something which can tell me if a Clojure source file is formatted according to the Clojure style guide.
12:09	weavejester	Something extensible, with optional formatters, in the same way Eastwood has optional linters
12:09	sdegutis	There are some times when I want a ")" on its own line, namely when I have a really long defroutes.
12:09	sdegutis	I don't know how to tell a code formatter that one pattern.
12:09	sdegutis	:(
12:10	Glenjamin	weavejester: how have you approached it knowing that GET/POST etc are binding forms ?
12:10	weavejester	Glenjamin: It'll be extensible, so you'll be able to add more rules.
12:10	weavejester	Glenjamin: I haven't figured out all the details yet, but I think they might be similar to Clojure's routes.
12:11	weavejester	i.e. just a long list of rules. if a rule returns nil it's ignored.
12:11	weavejester	Hard to do it any other way with things like backtracking indents
12:11	justin_smith	Glenjamin: if you look at clojure mode, it has a small set of rules (representing various macro / special form types and how they differ) and then a bunch of symbols are assigned to be indented according to each of those rules
12:11	weavejester	sdegutis: Fortunately I'm happy never having a ) on it's own line.
12:12	sdegutis	:)
12:12	justin_smith	sdegutis: ITYM :
12:12	justin_smith	)
12:12	weavejester	But the rules will be customisable.
12:12	Glenjamin	justin_smith: yeah, i was thinking of that as 1 rule, which there'd need to be a way to add more symbols to
12:12	technomancy	weavejester: the one exception I can think of is when you have a long list of data and you want to make it easy to insert a new entry
12:12	Glenjamin	always add in the second-last position :p
12:12	technomancy	haha, yeah not bad
12:13	Glenjamin	also helps for avoiding merge conflicts, add into a random position
12:13	justin_smith	technomancy: Glenjamin: clearly this calls for a new paredit command
12:13	technomancy	this is actually condoned in the hallowed text of riastradh's style guide
12:13	weavejester	technomancy: I personally care more about the appearance of the source than the diffs :)
12:13	justin_smith	"add new item at end of this list on its own line"
12:13	technomancy	weavejester: it's not the diff; it's hunting for the right number of parens to split off
12:13	technomancy	http://mumble.net/~campbell/scheme/style.txt
12:14	technomancy	"Exceptions to the Above Rule Concerning Line Separation"
12:14	weavejester	technomancy: paredit surely solves that problem?
12:14	technomancy	weavejester: hm, true. what about the comment one though?
12:15	weavejester	technomancy: #_ ?
12:15	technomancy	I guess just always use #_?
12:15	technomancy	right
12:15	technomancy	that sucks because you don't get font-lock
12:15	Glenjamin	maps are annoying in that sense
12:15	justin_smith	technomancy: paredit already fixes ; to add a line break for closing parens to work
12:15	weavejester	Anyway, I figure the rules can be customisable.
12:15	technomancy	justin_smith: yup yup. but it breaks the rules
12:15	weavejester	So you can set the rules you want in your project.clj file
12:16	Glenjamin	,{:a 1 :b 2 #_(:key val)} ; i guess
12:16	clojurebot	{:b 2, :a 1}
12:16	weavejester	Or use two #_#_
12:16	Glenjamin	what
12:16	technomancy	the formatter will certainly encounter ;; etc etc \n)) and needs to behave gracefully in its presence
12:16	Glenjamin	,{:a 1 :b 2 #_#_:key val}
12:16	clojurebot	{:b 2, :a 1}
12:16	Glenjamin	oh wow, i had no idea
12:17	weavejester	technomancy: it could be smart about it
12:17	weavejester	I have a few ideas about smart formatting.
12:17	weavejester	Like automatically adding in threading if a form is too deep.
12:17	justin_smith	Glenjamin: you can make really weird obfuscated code with stacked #_#_#_ without much effort
12:17	justin_smith	if you are trying to obfuscate, at least
12:17	weavejester	Smart newlines to split up lines over 80 chars
12:17	weavejester	etc.
12:18	justin_smith	weavejester: reiterating my interest :) godspeed
12:18	weavejester	I figure the first step is just to get something on parity with clojure-mode though
12:18	weavejester	Then add a lein plugin
12:19	weavejester	With a :check and :fix option
12:19	weavejester	So it can be used in CI to validate that a person's commit adheres to the project's format.
12:20	Glenjamin	if it can run as a server of some sort it'd be a neat way to negate the startup time
12:20	Glenjamin	assuming you're writing it in jvm clojure
12:20	weavejester	Incidentally, we need a protocol for reporting tests/linting. Currently we just have STDOUT
12:20	weavejester	Yeah, it's in jvm clojure.
12:20	weavejester	But it might work okay with lein-auto
12:20	weavejester	Because it doesn't do a project eval
12:21	weavejester	So "lein auto format :check"
12:21	weavejester	Which again means that a protocol for reporting tests/lints would be nice.
12:21	Glenjamin	auto format :fix would be trickier i imagine
12:21	weavejester	That just sounds like a bad idea :)
12:22	weavejester	Better to follow the slamhound route for that, I think
12:22	Glenjamin	being able to curl some text to a local server and get new text back would be neat
12:22	weavejester	Hm, I guess so
12:22	weavejester	Formatting as a service
12:23	Glenjamin	alias format='curl localhost:1234 -d @$1 > $1' or however you get pipes to rewrite a file
12:33	clgv	weavejester: using :configurator to modify (setIncludeProtocols) the SslContexFactory of the SslSelectChannelConnector instances of the jetty instance worker
12:34	weavejester	clgv: okay
12:34	sdegutis	weavejester: your auto-threading idea could be very problematic if any of the subforms are non-comformative
12:35	weavejester	sdegutis: What do you mean?
12:35	sdegutis	weavejester: unless I'm horrifyingly mistaken, there are several times when a form cannot be threaded based on whether the form is a macro or a function which can only be known at runtime
12:36	technomancy	it has to be ...
12:36	technomancy	thread-safe
12:36	technomancy	( •_•) ( -_-)~⌐■-■ (⌐■_■)>
12:36	weavejester	technomancy: :P
12:36	Glenjamin	oh dear, i laughed heartily at that
12:36	sdegutis	(alter technomancy + 1000000000)
12:36	weavejester	sdegutis: Do you have an example? Threading is a source transformation, so I don't see why it isn't safe.
12:37	sdegutis	weavejester: there are also things like (fn [] ...) which can't be put into a threading macro directly, but those are more easily spottable at the source level
12:37	sdegutis	weavejester: not off the top of my head
12:37	sdegutis	I was kind of hoping saying it might jog someone else's memory (mine is not very good) and they would jump in.
12:37	weavejester	The only way I can think of threading being unsafe is if it was in another source transformation macro.
12:38	sdegutis	Oh right, that's it.
12:38	sdegutis	You can't embed -> into ->>
12:38	sdegutis	Or compojure.core/GET too iirc.
12:39	sdegutis	Essentially any arbitrary form might happen to be a source-transforming macro.
12:39	Bronsa	,(-> [1 2] (->> (map inc) (reduce +)) inc)
12:39	weavejester	You can, you just need to be aware how it transforms the code.
12:39	clojurebot	6
12:39	weavejester	There's nothing special about (fn []) or (GET ...) that would stop them from being threaded
12:39	weavejester	The rules are always the same
12:40	luxbock	,((->> coll (map inc) (fn [coll])) [1 2 3])
12:40	clojurebot	(2 3 4)
12:40	sdegutis	weavejester: right, so unless I'm hideously mistaken, it would require a whitelist of known good forms, or at the very least a blacklist of known bad forms, when doing auto-threading
12:40	weavejester	Not really...
12:40	sdegutis	ok :)
12:40	Glenjamin	if it can be written as (f (g (h x))) it should always work as ->
12:41	technomancy	just make all your code point-free always
12:41	weavejester	Formatters don't need to be fullproof, firstly, especially if they're optional.
12:41	sdegutis	:)
12:41	weavejester	I'm sure I could write something that would break any formatter with macros if I tried.
12:41	weavejester	Unless the formatter was macro aware I guess
12:41	sdegutis	I have been known to be insidiously mistaken in the past, so I'll assume I'm wrong here.
12:42	weavejester	I agree it's possible, but since a formatter is just an aid, it shouldn't matter that I can craft a form that breaks it.
12:42	weavejester	Off the top of my head, I can't think of any deeply nested code transformation where you can't use threading.
12:43	teslanick	As long as crafting the form that breaks the formatter causes it to fail loudly
12:43	Glenjamin	i get this with my current lint tool, sometimes a rule breaks on some code where i disagree, occasionally i'll write my code differently because i still want the rule in general - or sometimes i'll go turn off the rule
12:43	sdegutis	weavejester: your lib sounds neat im curious to see how it plays out good luck
12:44	technomancy	yeah, glad to see this happening =)
12:45	weavejester	Glenjamin: yeah, I figure I'll take a similar approach with the formatter
12:45	Glenjamin	i've been very happy with eslint recently
12:45	sdegutis	what about eastwood?
12:45	Glenjamin	the level of configuration it provides is great
12:45	Glenjamin	per-file overrides are awesome too
12:46	weavejester	I'll try and get something released by this weekend. I just have defun-style indents and backtracking (i.e. protocol, type, proxy, reify) indents to sort out.
12:48	sdegutis	$dict great
12:48	lazybot	sdegutis: adjective: Very large in size.
12:48	sdegutis	Glenjamin: oh
12:49	Glenjamin	oh?
12:49	justin_smith	I am going to regret showing sdegutis the dict command
12:50	sdegutis	$dict going
12:50	lazybot	sdegutis: noun: Departure: comings and goings.
12:50	sdegutis	justin_smith: oh

12:52	weavejester	$dict complect
12:52	lazybot	weavejester: verb-transitive: To join by weaving or twining together; interweave.
12:52	weavejester	lazybot knows only how to complect things.
12:53	jaaqo	$dict transducer
12:53	lazybot	jaaqo: noun: A substance or device, such as a piezoelectric crystal, microphone, or photoelectric cell, that converts input energy of one form into output energy of another.
12:53	sdegutis	Wow lazybot. So wrong.
12:53	justin_smith	I may at least update that plugin to tell you other def's exist
12:53	sdegutis	justin_smith: but hopefully not to access them?
12:54	weavejester	lazybot should have a Clojure definition dictionary that it prefers
12:54	sdegutis	$dict have
12:54	lazybot	sdegutis: verb-transitive: To be in possession of: already had a car.
12:54	clojurebot	Titim gan éirí ort.
12:54	justin_smith	weavejester: yeah, right now it just does a simple wordnick api call
12:54	sdegutis	oh
12:55	justin_smith	$wotd
12:55	lazybot	justin_smith: abactinal: Pertaining to the surface or end opposite to the mouth in a radiate animal.
12:55	sdegutis	$wotd = perilous
12:55	lazybot	sdegutis: abactinal: Pertaining to the surface or end opposite to the mouth in a radiate animal.
12:55	sdegutis	It seems broken.
12:57	weavejester	I assume the word of the day is fixed
12:57	weavejester	per day
12:57	alpheus	I'm destructuring deeply nested maps where the keys (and structure) aren't known until run time. The code's getting cumbersome. Is there something that would help me do this?
12:57	justin_smith	https://www.wordnik.com/
12:58	justin_smith	alpheus: get-in
12:58	Glenjamin	alpheus: use let & get-in instead of destructuring?
12:58	alpheus	Yes, that's probably what I missed. Thanks!
12:59	sdegutis	weavejester: oh right, immutable; blech
12:59	sdegutis	we need a mutable subclass of WOTD
13:00	Glenjamin	WOTD is an identity that changes over time
13:01	justin_smith	&(let [data {:a 0 :b 1 :c {:d {:e 3}}} path '(:c :d :e)] (get-in data path))
13:01	lazybot	⇒ 3
13:01	sdegutis	alpheus: Clojure's motto is "work smaerter not harder"
13:01	sdegutis	alpheus: Clojure's motto is "use streams not recursion"
13:01	llasram	$dict smaerter
13:01	lazybot	llasram: Word not found.
13:01	sdegutis	alpheus: Clojure's motto is "immutable decomplection"
13:02	weavejester	I think Clojure's more about aggressive simplification.
13:02	technomancy	I thought it was "simple yet powerful"
13:02	technomancy	or is that just the sdegutis motto
13:02	sdegutis	alpheus: Clojure's motto is "simple, yet powerful"
13:02	Glenjamin	i thought it was "always be decomplecting"
13:02	sdegutis	technomancy: no, it's just that probably about 2/3 of all projects have that phrase in their readme
13:02	alpheus	alpheus's motto is "I'm not smart like you people are"
13:02	teslanick	alpheus: That's my motto too.
13:02	weavejester	Power comes from simplification, I think :)
13:03	Glenjamin	aha, here we go: https://pbs.twimg.com/profile_images/1630228544/fakerichhickey.jpg
13:03	sdegutis	llasram: oh sorry, i meant smærter
13:03	danielcompton	Rich is nice so we are nice?
13:03	technomancy	my motto http://www.funnyjunk.com/funny_pictures/1906060/I
13:03	sdegutis	danielcompton: no that is not our motto
13:03	weavejester	The new transducers are effectively a simplification, by factoring out the conj
13:03	sdegutis	alpheus: Clojure's motto is "Rich is hipster so we are hipster"
13:03	teslanick	I'm curious if this is an insane idea: I want to put to a channel and get some value back when a consumer processes the message I sent it. I played with callback functions and a "callback channel" -- is there an idiomatic way of doing something like this?
13:04	sdegutis	weavejester: well they're also a decomplexion
13:04	justin_smith	teslanick: pass in a channel to put the result onto
13:04	weavejester	Or return a channel, perhaps
13:04	mdrogalis	weavejester: Maybe 2 steps forward in terms of simplicity, 1 step back. You still need to be aware of stateful transducers in certain contexts.
13:04	weavejester	(<! (do-something foo))
13:05	weavejester	Like a promise
13:05	weavejester	mdrogalis: Yes, maybe.
13:05	mdrogalis	Not complaining though. :)
13:05	sdegutis	I want to add a maybe-monad to Clojure.
13:05	teslanick	Ok. I wrote a function called putback! that takes a channel to put to and a value. It returns a channel upon which a result will be passed. The other side knows how to interact with the "chan-back"
13:07	weavejester	Monads are a bit tricky without dispatch on return.
13:08	technomancy	you need pattern matching or it's just going to be super tedious
13:11	sdegutis	At about 3:07 into it, the Graduation song gets really epic.
13:12	sdegutis	It goes on until about 3:34... It may be needful to put that sub-section on repeat a few times for maximum effect.
13:12	sdegutis	Anyway, I'm abusing Clojure metadata within defn.
13:13	sdegutis	I've got a meta-handler which looks at a route fn's metadata, so that I can just define (defn ^:login view-page-route [] ...) and it requires the user to login first, or redirects them.
13:14	weavejester	sdegutis: Why not use middleware?
13:14	ticking	does anybody know at the to of their head if nRepl is designed to handle multiple evals in parallel in one session?
13:15	sdegutis	weavejester: That's what I mean by a metahandler :)
13:16	weavejester	sdegutis: But why not apply the middleware directly to the routes?
13:17	sdegutis	weavejester: you mean instead of putting ^:login on the end-point route handler fn's var?
13:18	sdegutis	weavejester: because unless I'm appallingly mistaken, wrapping a route in the middle of a routes-chain is going to short-circuit the rest of the routes if it matches it halfway but not the remainder of the way
13:18	weavejester	sdegutis: Yes, you could wrap-requires-login over the group of routes that require logins.
13:18	weavejester	sdegutis: I don't understand what you mean by that.
13:20	sdegutis	weavejester: for example, I have (defroutes foo (GET "/" ...) (wrap-require-admin (GET "/admin" ...)) (GET "/cart" ...)) -- this is going to prevent /cart from ever being valid for non-admins, even though it's outside wrap-require-admin, unless I'm disgustingly mistaken
13:20	justin_smith	ticking: I don't know this for a fact, but my expectation is that it would not parallelize for one session (connection) but if you opened another connection on the same server, that would run in parallel -- checking now
13:20	sdegutis	I ran into this a year ago and tracked it down to something like that.
13:23	justin_smith	https://github.com/clojure/tools.nrepl/blob/master/src/main/clojure/clojure/tools/nrepl/server.clj#L43 ticking: the logic is here - each connection is in its own future, and each message in the handler is also a future in a block that uses (recur) after spawning the request in a future.
13:23	justin_smith	I used "future" one too many times describing the handler, but the code should be clear (see accept-connection and handle)
13:23	ticking	justin_smith: nice thanks, so sending many :op :eval in succession should not break nrepl right?
13:24	justin_smith	doesn't look like it from that code
13:24	justin_smith	ticking: unless you send enough requests to starve the thread-pool I guess...
13:24	ticking	justin_smith: I'm currently trying to add interrupt to gorilla repl, it's really about time :D
13:25	justin_smith	nice
13:25	ticking	so thanks a lot :D
13:25	weavejester	sdegutis: You can use the `wrap-routes` function in Compojure to wrap inside of routes.
13:25	sdegutis	weavejester: Thanks.
13:25	weavejester	sdegutis: It was made specifically with the idea of authentication failing in mind, though it's applicable for a lot more.
13:30	sdegutis	weavejester: That is a very useful feature.
13:31	weavejester	sdegutis: I thought so, but I don't know anyone who's using it yet :)
13:31	sdegutis	weavejester: I would have used it a year ago except I didn't know it existed, and when I found it in the source, I didn't understand how/why/when to use it.
13:32	weavejester	sdegutis: I didn't think it was a year old...
13:32	sdegutis	Oh maybe not?
13:32	sdegutis	weavejester: And right now I'm not sure I can use it, because I've restructured my app to decomplect the route handling function from the route itself.
13:34	sdegutis	weavejester: Currently I have a list of tuples which I transform into handlers (partially using (make-route)) and then pass to (apply routes).
13:35	sdegutis	It allows me to write a routes.clj file very similarly to a routes.rb file, containing [[:get "/" :home/show-home-page] [:get "/videos" :home/redirect-to-home-page] [:get "/admin" :admin/show-admin-page]] etc
13:41	weavejester	sdegutis: Hm, okay, but why would that stop wrap-routes from working?
13:41	sdegutis	weavejester: because I would need to wrap a subset of them -- oh wait, I can manipulate collections in Clojure.
13:44	weavejester	bbl
14:56	andyf	Bronsa: Clj-1591 comment discussion had a small test case that has symptoms like clj-1241 even after that fix was applied. No need for you to look at it, but in case you are interested ...
14:58	andyf	Different exception, so not identical symptoms, but var that is bound without aot is unbound when using aot
14:59	Bronsa	andyf: ah, AOT is involved. might be a completely different issue then, I'll take a look
15:00	andyf	Tom Crayford created the test case, linked in comments
15:17	daniel___	i wonder if anyone can help me with a friend problem https://gist.github.com/danielstockton/649ceff075b793007e27 ?
15:17	daniel___	my workflow ring handler is never called
15:17	daniel___	and i can't work out why
15:18	daniel___	im trying a POST to the /api/session endpoint
15:22	justin_smith	daniel___: that call to run-jetty won't see redefinitions of app, but if you change it to (run-jetty #'app ...) it will
15:22	justin_smith	daniel___: not that that neccissarily caused your problem though
15:23	daniel___	that includes redefinitions of middleware and things that make up app?
15:23	daniel___	i seemed to be seeing changes when i made them further up without needing a restart
15:23	justin_smith	right, it won't see any of those redefinitions
15:23	justin_smith	hmm...
15:26	daniel___	justin_smith: changed it, now it logs all the calls to static resources
15:26	justin_smith	OK, I guess that's proof it's reloading.
15:27	daniel___	interested in why thats the case, but dont want to detract from my friend workflow issue
15:28	justin_smith	frankly, I have only been confused by friend and never got it working
15:28	justin_smith	hopefully someone else can help you
15:28	daniel___	i read through the documentation when i had some time earlier, away from the code, and i thought i got the concepts
15:29	daniel___	but apparently not
15:30	daniel___	"Incoming requests are always run through the configured workflows prior to potentially being passed along to the secured Ring application" mine don't seem to be..
15:36	raboid	what does @() do in Clojure? Having a hard time finding any documentation for it
15:37	joegallo	looks for deref
15:37	llasram	raboid: It's a reader macro:
15:37	andyf	raboid: @form turns into (deref form)
15:37	joegallo	,`@foo
15:38	llasram	,`(@example)
15:38	clojurebot	(clojure.core/deref sandbox/foo)
15:38	clojurebot	((clojure.core/deref sandbox/example))
15:38	llasram	Yeah, joegallo's was better
15:38	llasram	(inc joegallo)
15:38	lazybot	⇒ 6
15:38	andyf	Clojure cheatsheet has a section on these
15:39	andyf	Which could be better at linking to more details
15:40	raboid	Okay thanks ya'll
15:44	raboid	Could anyone familiar with aleph explain why this only handles the first request sent to it? https://gist.github.com/raboid/b9629fc24f3524fbdec4
15:44	raboid	Works perfect on the first request, but after that it never seems to call the handler anymore?
16:02	Bronsa	andyf: I have a fix
16:03	andyf	Bronsa: Your awesomeness level is up to its usual high, then :-)
16:04	Bronsa	andyf: it requires generating 7 more instructions for every interned Var though :/ but I don't think there's another way to fix it
16:05	andyf	Tom says he will be creating a separate ticket for this issue, perhaps today, but mgr may not mind if you do
16:05	andyf	It does seen independent of original ticket
16:05	Bronsa	yeah it's unrelated-ish
16:06	Bronsa	ah I think I can make this better.

16:21	aaelony	I wish I could pastebin a line of sample data, but I'm not allowed to do that :(
16:21	aaelony	I think it's a matter of escaping the incoming string
16:22	aaelony	for example, if I manually replace " with \" at the repl for a line of data, parse-string works just fine

17:12	cfleming	Bronsa: Not being able to do that kills me in Cursive
17:12	Bronsa	cfleming: you can either change like 3 lines in the Compiler to allow that or you'll need to use genclass/proxy
17:12	cfleming	Bronsa: To do that in Clojure proper I'd have to fork and modify the compiler - could I do that with tools.* in a macro?

17:13	cfleming	It's only 3 lines? I'd assumed I'd need new forms for that.
17:13	weavejester	verma: ::hello includes the current namespace
17:13	weavejester	,::hello
17:13	clojurebot	:sandbox/hello
17:13	verma	oh what? nice
17:13	verma	TIL
17:13	verma	thanks weavejester
17:13	verma	(inc weavejester)
17:13	lazybot	⇒ 11
17:13	Bronsa	cfleming: no I mean, you can make deftype/reify extend an abstract class rather easily
17:14	weavejester	verma: You can also use it to include namespace aliases as well
17:14	weavejester	verma: So ::str/foo might become :clojure.string/foo
17:14	weavejester	,::str/foo
17:14	clojurebot	#<RuntimeException java.lang.RuntimeException: Invalid token: ::str/foo>
17:14	verma	oh
17:14	weavejester	Looks like lazybot doesn't include clojure.string
17:14	verma	as long as str can be resolved?
17:14	weavejester	yeah
17:14	justin_smith	&(require '[clojure.string :as s])
17:14	lazybot	⇒ nil
17:14	cfleming	Bronsa: Interesting, that might be a good approach since I can bundle my own Clojure. In fact I'd only need to use that for compilation, right? Since I'm AOT'ing.
17:15	justin_smith	&s/foo
17:15	lazybot	java.lang.RuntimeException: No such var: s/foo
17:15	justin_smith	&::s/foo
17:15	lazybot	java.lang.RuntimeException: Invalid token: ::s/foo
17:15	justin_smith	erm
17:15	weavejester	&(do (require '[clojure.string :as s]) ::s/foo)
17:15	lazybot	java.lang.RuntimeException: Invalid token: ::s/foo
17:15	Bronsa	cfleming: or you could do that with t.a/t.e.jvm withouth forking yeah but I'd just patch the Compiler if I were you
17:15	justin_smith	weird
17:15	weavejester	Probably because they're in the same form.
17:15	weavejester	And the separate forms are sandboxed
17:15	Bronsa	cfleming: right. I actually already implemented that years ago, let's see if I can find that patch
17:15	verma	brewing up a repl and trying it
17:15	weavejester	It works in an actual Clojure file anyway ;)
17:16	cfleming	Bronsa: Ok thanks - a patch would be fantastic, if not I can probably work it out.
17:16	verma	so I would use to create a namespaced keyword sort of?
17:16	justin_smith	&(namespace ::foo/bar)
17:16	lazybot	java.lang.RuntimeException: Invalid token: ::foo/bar
17:16	cfleming	Bronsa: I'm also going to modify them to allow requiring their namespace in clinit.
17:16	justin_smith	wat
17:16	verma	test.clj -> ::hello is the same as :test/hello in a separate file?
17:16	justin_smith	&(namespace :foo/bar)
17:16	lazybot	⇒ "foo"
17:17	justin_smith	verma: yes, it is precisely making a keyword that has a namespace
17:17	verma	nice
17:17	verma	got it
17:17	verma	(inc justin_smith)
17:17	lazybot	⇒ 147
17:17	cfleming	Bronsa: Of course, it'll need more work to allow superclass method invocation.
17:17	Bronsa	cfleming: https://github.com/Bronsa/clojure/commit/915aadc0cb8a604b6ef4976d2f19a2b1dfb994f5
17:17	Bronsa	don't know if that still applies
17:18	cfleming	Bronsa: That's fine, I can modify it - thanks so much, that might just save my life.
17:21	cfleming	Bronsa: I'm still not sure what a good syntax would be for superclass invocation, but I don't always need to do that.
17:21	cfleming	Bronsa: Just being able to extend is really helpful.
17:23	Bronsa	cfleming: yeah with that patch only it'll only work for abstract classes that don't declare a constructor -- it simply invokes the no-arg super ctor
17:26	cfleming	Bronsa: Ohhh... right, I'll definitely need the super constructor call. I'd have to add syntax similar to proxy for that, but that's probably a pretty simple modification to your patch.
17:28	cfleming	Bronsa: If I decide I do want a separate form, t.a/t.e.jvm should allow it in a macro, right? Does t.e.jvm support AOT compilation yet? I know that wasn't there a while back.
17:30	Bronsa	cfleming: we're not there yet unfortunately. I still have a major bug to fix in t.a.jvm before I get to start playing with t.e.jvm again
17:31	Bronsa	cfleming: I'll be honest, right now it's probably less work to patch Compiler.java than implement that by extending t.e.jvm (without patching it)
17:32	augustl	in the name of interop and legacy, is there a way to get a servlet handler object implementation from a ring handler function?
17:33	weavejester	augustl: You can get the ServletContext, Request and Response objects when running in a servlet container.
17:33	augustl	weavejester: the other way around, so to speak :) I'm in a setting where I have some servlets and map them to a servlet context with Java code, and want to do that with a ring handler as well
17:34	l1x	is there a way to get to know the name of the thread I am in that was created with (async/thread ... ) ?
17:34	weavejester	augustl: Oh, well you can create a servlet object using the ring/ring-servlet library.
17:34	augustl	weavejester: ah, nice. Thanks!
17:34	Bronsa	cfleming: it's not summer and I have lessons now, I don't have the time to actively work on all the 5 tools.* libraries so I gave priority to t.a/t.a.jvm since those are the more useful -- t.e.jvm is on the bottom of the list i.e. I'll work on it when there will be no more issues with the other libs.
17:34	weavejester	augustl: There are functions for creating a servlet via a proxy, and via gen-class
17:35	justin_smith	,(.getName Thread/currentThread)
17:35	clojurebot	#<CompilerException java.lang.RuntimeException: Unable to find static field: currentThread in class java.lang.Thread, compiling:(NO_SOURCE_PATH:0:0)>
17:35	augustl	weavejester: very nice
17:36	justin_smith	&(.getName (Thread/currentThread))
17:36	lazybot	⇒ "Thread-5691"
17:36	justin_smith	l1x: ^^^
17:37	l1x	thanks!
17:37	l1x	justin_smith: your suggested way of dealing with concurrency works
17:37	l1x	i am testing it on stage now
17:37	cfleming	Bronsa: Sure, no problem - just wondering where it was at. Thanks for the help!
17:37	justin_smith	l1x: cool, it has worked for me in that past :)
17:37	cfleming	Bronsa: I'll fix the compiler since I more or less understand that.
17:38	Bronsa	"fix" :) let me know if you have any issues -- happy to help
17:38	l1x	justin_smith: i might poke you to review my code (few lines really) if you have time because it is opensauce
17:39	justin_smith	l1x: I am in and out today (at a pub on my laptop right now) but happy to look at it if yo catch me at a good time
17:39	l1x	:d
17:39	l1x	nice tahnks
17:40	Bronsa	cfleming: btw don't know if this could help but I wrote https://github.com/Bronsa/neurotic a while ago. IIRC ztellman also has a lib that does something similar.
17:40	l1x	Cannot find field currentThread for class class java.lang.Thread
17:40	l1x	hmm
17:40	l1x	ohh
17:40	TEttinger2	aaelony: still there?
17:40	TEttinger2	my connection is not great
17:41	aaelony	TEttinger2: hi
17:41	justin_smith	l1x: notice my second example, the one that worked
17:41	justin_smith	l1x: not a static field, but a method call
17:41	l1x	yes! :)
17:41	TEttinger2	(clojure.string/escape "hello there, \"friend-o\"" { \" "\"" } )
17:41	TEttinger2	,(clojure.string/escape "hello there, \"friend-o\"" { \" "\"" } )
17:41	clojurebot	"hello there, \"friend-o\""
17:42	TEttinger2	,(clojure.string/escape "hello there, \"friend-o\"" { \" "\\\"" } ) ; may be what you want
17:42	clojurebot	"hello there, \\\"friend-o\\\""
17:42	aaelony	TEttinger2: I was playing around with clojure.string/escape but I didn't try that exactly. Let me give it a shot.
17:42	TEttinger2	,(println (clojure.string/escape "hello there, \"friend-o\"" { \" "\\\"" } ))
17:42	clojurebot	hello there, \"friend-o\"\n
17:42	TEttinger2	,(print (clojure.string/escape "hello there, \"friend-o\"" { \" "\"" } ))
17:42	clojurebot	hello there, "friend-o"
17:43	TEttinger2	substituting "\"" for \" is the same as "\"" for "\""
17:44	aaelony	TEttinger2: Actually, looking at the things I had tried, what you mention was among them.
17:45	aaelony	TEttinger2: and produces the error "com.fasterxml.jackson.core.JsonParseException: Unrecognized token 'I': was expecting 'null', 'true', 'false' or NaN"
17:45	TEttinger2	can you just make up some names-changed sample data?
17:45	TEttinger2	like change any keys like :name to :foo
17:46	aaelony	TEttinger2: I call (last) on the line before, I think that may not always be valid. In any case, it is something silly in the data that is causing this. It will be found...!
17:48	TEttinger2	null, true, false, or NaN should probably mean that it's trying to get a boolean and it's getting something like "I wish I had a pony", just with the quotes not read correctly
17:48	cfleming	Bronsa: That does look really useful, thanks - I'll investigate that too.
17:50	TEttinger2	if ztellman and Bronsa combined their powers we'd have an unstoppable Clojure juggernaut
17:54	andyf	That has already occurred
17:55	aaelony	perhaps I can hint it to expect a string....
17:57	dbasch	aaelony: do you know if your json is well formed? i.e. if you paste into a json validator does it validate?
17:58	dbasch	it looks like you’re reading a string that’s missing a quote, so the parser doesn’t know what to make of it
17:58	aaelony	dbasch: it is well formed for the rows I have tried. If I manually replace " with \" for the cases I have tested, it works just fine
18:00	hiredman	github's highlighting seems to thing most of the code in tools.reader is a string literal :/
18:00	dbasch	aaelony: what happens if you try to parse {"a":1,"b":2}
18:00	bbloom_	hiredman: i think they've switched github's highlighter to use the same codebase as atom as a ploy to get ppl to contribute better highlighting for their editor
18:01	TEttinger2	aaelony, so there are strings like this in your data: "key": "Quoth the raven, "Nevermore." And he was totes right."
18:01	aaelony	It is certainly true that the data contains semi-colons, punctuation, and all sorts of stuff. I'm in the process of adding things to escape as I find them.
18:01	hiredman	bbloom_: :\|
18:02	TEttinger2	semicolons are fine in strings... how are you parsing this...
18:02	aaelony	TEttinger2: There are strings like "a":"Out out darn spot. ;)"
18:03	TEttinger2	that shouldn't be any problem
18:03	aaelony	at some level, it's likely true that some kind of preprocessing or cleaning will have to act on this before the json parser will work.
18:04	TEttinger2	that should parse as the string "Out out darn spot. ;)"
18:04	aaelony	it's just not easy to identify from the error messages what the offending problem strings are
18:04	dbasch	aaelony: it’s either well formed json or it’s not. If it is, it should parse
18:04	aaelony	I will half the data until it works. then backtrack.
18:04	dbasch	you should not need to escape anyything
18:05	aaelony	I've used this library before, without issues.
18:05	dbasch	which library?
18:05	aaelony	It's a data thing. Thanks guys. I'll just hunt for the data problem.
18:05	aaelony	jackson
18:05	dbasch	if it’s not well-formed json and you say it is, we can’t help you
18:06	aaelony	dbasch: thanks
18:07	aaelony	There are multiple foreign languages in the data as well that may be interfering as well.
18:07	dbasch	aaelony: it’s either json or it isn’t
18:08	aaelony	thanks dbasch: It is supposed to be. I didn't produce it. I'll take this offline now. thanks to everyone.
18:09	dbasch	aaelony: keep in mind that foreign characters have nothing to do with it
18:10	aaelony	there may be lots of things in there, unicode, etc... I'm not as certain as you are.
18:11	dbasch	aaelony: unicode is absolutely fine. I hate to repeat myself, but your json is well-formed or malformed and the rules are pretty simple.
18:12	aaelony	I'm leaving this conversation now

21:31	danielcompton	take your unicode child to work day
21:39	kenrestivo	i've been having strange problems with clojure.tools.namespace.repl/refresh blowing "namespace not found" errors
21:39	kenrestivo	where, the namespaces are definitely there, the source is all there, and i can load them manually no problem
21:49	akkad	anyone here using newrelic with clojure?
21:51	devn	Given {:foo [{:bar 1} {:bar 2}], :baz [{:bar 3} {:bar 4} {:bar "hello"}] ...}, I want [[1 3] [1 4] [1 "hello"], [2 3] [2 4] [2 "hello"]]
21:52	kenrestivo	someone just asked almost that exact question yesterday
21:52	kenrestivo	i think it was a reduce-kv answer
21:53	justin_smith	something like (map #(map bar %) (vals data)) I think
21:53	justin_smith	makes those mapvs if you really need vectors
21:54	justin_smith	err wait
21:54	justin_smith	there is structure there I did not notice, never mind, that is wrong
21:54	justin_smith	brb
21:55	kenrestivo	the :foo and :baz seem almost superfluous.
21:55	devn	you can treat them that way, sure
21:56	mgaare	I don't know what I'm doing wrong with cljx. I've got a .clj ns that requires a .cljx ns, and it complains it can't find it and exceptions out even of the lein cljx once task
21:58	danielcompton	mgaare: do you have code samples you can share?
21:58	andyf	kenrestivo: Shot in the dark: do any of your source files contain namespace names that do not correspond to the file names? Eastwood can quickly tell you if so (1st check it does)
21:59	mgaare	danielcompton: yeah, hangon
21:59	kenrestivo	andyf: ooh, cool, will try. i'm pretty sure not because lein-check is copacetic
21:59	andyf	I don't think Lein check will tell you that
21:59	kenrestivo	but running it through the eastwood/kibit gauntlet sounds like a fine idea
22:00	danielcompton	kenrestivo: kibit will blow up if you're doing anything too weird so there's that
22:00	andyf	It is a not uncommon mistake that can lead to subtle problems or un executed tests
22:05	kenrestivo	wow, eastwood is pretty damn cool.
22:05	kenrestivo	tho it is very upset about timbre log/info, complaining about: (clojure.core/not= file__5335__auto__ "NO_SOURCE_PATH")
22:06	kenrestivo	specifically constant-test: Test expression is always logical true or always logical false: (clojure.core/not= file__5335__auto__ "NO_SOURCE_PATH")
22:06	andyf	kenrestivo: I just verifies that Lein check does not catch all cases of file name / namespace mismatch. It did on a core.clj file in a new project I created , but not on another file I created with bad namespace
22:06	mgaare	danielcompton: https://gist.github.com/mgaare/7118a0975c13099ef29d
22:08	kenrestivo	eastwood also complained about a missing var, which wasn't. i had (:require [foo.bar :as bar]) and then (bar/baz ...) later, and it complained that bar was not found
22:08	andyf	kenrestivo: Yeah, since it macro expands first then does its checks, some macros lead to too many warnings. I have a thought on a semi-convenient way to selectively shut those off, but not yet implemented
22:08	kenrestivo	it thought bar was a var not a namespace alias
22:09	danielcompton	mgaare: what happens if you remove literal
22:09	andyf	kenrestivo: Open source project? If so, a github issue would be welcome
22:09	mgaare	danielcompton: remove as a dep from jena?
22:10	kenrestivo	no, sadly, not. if i can get a minimum repro i will tho
22:10	andyf	Was bar/baz inside back quoted form ?
22:11	kenrestivo	nope
22:11	danielcompton	mgaare: I mean just remove the file
22:11	kenrestivo	hmm, actually, it was first arg to swap! so maybe there's some macro magick in swap!
22:11	danielcompton	mgaare: temporarily delete it
22:12	andyf	Ok. Then it might be a case I haven't seen before.
22:13	kenrestivo	andyf: cool tool though. if it wasn't blowing so many spurious warnings about constant-test, i'd probably run it often
22:14	andyf	I'll create a test case like that - could be significant. Swap! is not a macro, but I am often finding new cases I have not seen before like this
22:15	mgaare	danielcompton: ok, I just removed all references to .cljx namespaces from .clj namespaces, ran lein cljx once, reinstated the references, and now a repl starts up properly.... this doesn't seem like how cljx is spose to work though
22:15	andyf	I tend to err on the side of "warn if not sure" and then quiet down new cases that are too noisy as I discover them
22:15	danielcompton	mgaare: did you try doing a lein clean before the lein cljx once?
22:15	mgaare	yea
22:16	andyf	Sorry, I guess not much help on the tools.namespace weirdness, though
22:18	kenrestivo	yeah, it's very odd. it's dying on every required namespace
22:19	andyf	Do you have example timbre logging call that gives warning for me to reproduce ?
22:21	kenrestivo	it's just log/info
22:23	andyf	You can now disable constant-test linter globally in your project either on cmd line or in project.clj file. E.g. Lein Eastwood '{:exclude-linters [:constant-test]}'
22:23	kenrestivo	interestingly, the namespace problem goes away if i gut ALL the files, removing everything except the ns decl :-/
22:23	mgaare	ah, I think user.clj was at fault
22:23	kenrestivo	so now it's a house-of-cards situation, i'll start adding stuff in do a bifurcation check to find where it breaks
22:24	andyf	The part in quotes can be value of :eastwood key in your project.clj file
22:24	kenrestivo	oh cool
22:26	zRecursive	Is it convenient using Clojure to create a Maxima-like software ?
22:29	andyf	Probably as convenient as it would be in scheme, Common Lisp, etc
22:29	andyf	Still work :-)
22:29	zRecursive	hope so
22:31	andyf	There is a library called expresso on github that is a start, but not sure how much is there
22:32	zRecursive	thanks
