00:00	talios	:)
00:00	talios	I'm surprised you've not had Rich on:)
00:00	cemerick	I suspect he'll be on Relevance's before mine :-)
00:02	talios	what you really need is me :) but then other than starting the maven plugin I couldn't really say more :) hah
00:03	cemerick	Man, scheduling a MA<=>NZ recording would be brutal for someone
00:03	brehaut	lol
00:03	brehaut	what time is it in MA at the moment?
00:03	brehaut	(its 4pm in NZ)
00:04	talios	cemerick CTCP REPLY time 2012-04-03 04:00:16 +0000
00:05	cemerick	midnight, 4/3
00:05	talios	if thats the case, an mid-morning NZDT would be afternoon/early evening for you
00:05	talios	ish
00:06	y3di	talios: mind sending me an invite as well?
00:06	talios	y3di: PM me an email address and twitter handle
00:06	talios	(you need both)
00:10	muhoo	my favorite part of the prismatic demo was where he told us how awesome it was
00:10	cemerick	hah
00:12	brehaut	so far im impressed
00:18	talios	brehaut: I posted my REST talk video finally as well
00:18	jwpalmer	hey there
00:18	brehaut	talios: oh cool
00:18	brehaut	got a link?
00:18	jwpalmer	anyone else looking for prismatic invites?
00:19	jwpalmer	i've got 'em
00:19	archaic	any idea when the clojure/west talks will get uploaded?
00:19	talios	brehaut: http://www.youtube.com/watch?v=3IhknRRERw0
00:19	brehaut	thanks
00:25	replaca	archaic: I think Alex told me it would start about 4-6 weeks after the conference and roll out over a couple of months
00:31	autodidakto	technomancy: thanks to your slamhound readme, i'm going to give william gibson another shot.
00:33	y3di	where can i find documentation on -> ? (I can't google it because theyre symbols_
00:34	muhoo	y3di: it's the threading macro
00:34	xeqi	http://clojuredocs.org/clojure_core/clojure.core/-%3E
00:34	muhoo	y3di: ##(doc ->)
00:34	lazybot	⇒ "Macro ([x] [x form] [x form & more]); Threads the expr through the forms. Inserts x as the second item in the first form, making a list of it if it is not a list already. If there are more forms, inserts the first form as the second item in second form, etc."
00:35	muhoo	(doc foo) has saved my tuchus many times
00:35	clojurebot	#<ExecutionException java.util.concurrent.ExecutionException: java.lang.NoClassDefFoundError: Could not initialize class clojure.lang.RT>
00:35	muhoo	&(doc .)
00:35	lazybot	⇒ "Special: .; The instance member form works for both fields and methods.\n They all expand into calls to the dot operator at macroexpansion time."
00:36	muhoo	omg slamhound, that's fantastic
00:37	autodidakto	muhoo: :P
00:37	muhoo	like what jdee does in emacs
00:37	muhoo	has a feature to add all the damn imports when ant says it can't find the symbol
00:41	y3di	ah so -> is kinda reverse clojure
00:41	muhoo	i remember seeing a file in some of ztellman's code somewhere, where the (ns) form was longer than the code in the file.
00:42	muhoo	y3di: it's kind of like foo().bar().baz() in javascript or java
00:42	muhoo	instead of (baz (bar (foo)), yeah
00:43	muhoo	i find it easier to write code that goes (baz (bar (foo)) as i'm going along, then i look at it, and go, uggh, it'd be clearer as (-> foo bar baz), and rewrite it
00:44	y3di	(foo) just evaluates to foo right?
00:44	eggsby	whatever returns from the first param of -> gets passed as the first param to subsequent forms
00:44	muhoo	^ what he said
00:45	autodidakto	,(doc ->>)
00:45	clojurebot	#<ExecutionException java.util.concurrent.ExecutionException: java.lang.NoClassDefFoundError: Could not initialize class clojure.lang.RT>
00:45	y3di	right, seems simple enough thanks
00:57	brehaut	rplevy has gone crazy with the arrow macros apparently
01:02	seancorfield	Raynes: you crack me up dude... yeah, cat shows... I know, an hour and a half ping time... so sue me :)
01:16	mbriggs	anyone use korma before for sql?
01:16	brehaut	~anyone
01:16	clojurebot	Just a heads up, you're more likely to get some help if you ask the question you really want the answer to, instead of "does anyone ..."
01:16	mbriggs	trying to find out if their entity relationships/with feature uses joins or sub selects
01:16	mbriggs	yeah, sorry about that
01:17	brehaut	i havent used it in a while, but from memory: secondary selects
01:17	mbriggs	yeah, i kinda figured
01:17	y3di	why do people make certain things macros over functions? couldn't defn have been a function instead of a macro?
01:19	brehaut	macros are used when the evaluation rules need to be customized
01:20	brehaut	for instance, to capture the body of the fn definition rather than try to evaluate it
01:21	muhoo	those swiss arrows are crazy, but some of those "branching arrows" i wonder why just map wouldn't work
01:21	muhoo	the <> one i could imagine using though
01:23	muhoo	also "-<<:p", really
01:23	muhoo	ok, enough bikeshedding, back to work for me
01:30	laurus	The version of Leiningen in the Debian Wheezy repository relies on Clojure 1.2, not 1.3, although 1.3 is available. Why is this?
01:32	brehaut	the version of clojure that lein uses doesnt effect the version of clojure your project uses
01:33	mk	what languages are people here coming to clojure from?
01:33	laurus	brehaut, I see. Thanks!
01:34	laurus	mk, in my case Java and Python and some dabbling in Lisps.
01:34	brehaut	mk: http://cemerick.com/2011/07/11/results-of-the-2011-state-of-clojure-survey/
01:34	brehaut	the big three are java, ruby and python
01:35	brehaut	in my case: Python, JS, C#, Haskell
01:36	mk	brehaut: excellent, thanks
01:37	mk	I'd be interested in knowing how many people knew a lisp before
01:37	brehaut	common lisp + scheme = 7% ;)
01:39	mk	brehaut: it'd be nice to see the other responses drawn according to how much people actually use it
01:39	mk	oh excellent, raw data is available
01:40	cemerick	of course, I discretized the data quite a lot by asking the question that way
01:41	cemerick	i.e. the distribution of prior languages would have been far more equalized if people could have listed e.g. their last 4 languages or something
01:43	mk	right
01:43	mk	the raw data is not pretty
01:53	wei_	what's the idiomatic way to generate a seq of items from a series of http calls? given a (fetch-as-json url) function
01:54	amalloy	map
01:54	wei_	the returned json has a :next field url for getting the next page
01:54	amalloy	iterate
01:55	wei_	oh, nice
02:23	muhoo	i'm having a tough time getting lein 1.7 to compile java sources as well as clj sources. i've got :java-source-paths set, but it's silently not compiling any java
02:39	wei_	amalloy: thanks for the tip. works beautifully, except--
02:40	wei_	fetch-as-json returns a batch of stuff. so I have
02:40	wei_	([1 2 3] [4 5 6] [7 8 9]) instead of [1 2 3 4 5 …]. how to concat lazily?
02:40	amalloy	&(doc mapcat)
02:40	lazybot	⇒ "([f & colls]); Returns the result of applying concat to the result of applying map to f and colls. Thus function f should return a collection."
02:42	seancorfield	mk: define "knew a lisp"... many ppl encountered lisp at college before they went on to other languages... but does that mean they _knew_ a lisp?
02:42	wei_	is there an iterate-cat ?
02:42	Raynes	seancorfield: I rarely forget things people tell me. ;)
02:42	amalloy	see also tree-seq
02:43	Raynes	Except that time I thought amalloy's dad was named 'Kirby'.
02:43	Raynes	Apparently that was incorrect.
02:43	mk	seancorfield: something like reasonably proficient, used it for at least personal projects
02:44	seancorfield	ok, then yeah, i knew lisp... years ago
02:44	seancorfield	but i came to clojure from a different route
02:48	Raynes	He took a left at the Y combinator.
02:49	andyfingerhut	When you come to a fork in the road, take it!
02:53	unlink	How do I create module-level globals which depend on configuration (e.g. command-line arguments)?
02:53	unlink	i.e. not in the main module.
02:54	andyfingerhut	you mean global to a namespace?
02:54	mk	I had a look at the raw data of that survey, it's interesting that most of the people who've stuck around longest are coming from CL, ada... a surprising number are staying from C++ and Javascript
02:54	Raynes	devn: http://slim-lang.com/index.html A templating language alternative to HAML that I can get behind.
02:54	andyfingerhut	You could do it with (def ^:dynamic my-global-var "default value")
02:55	andyfingerhut	Then do (binding [my-global-var (nth command-line-args 1)] <useful code here calling functions that use my-global-var)
02:56	unlink	andyfingerhut: yes, that is what I mean.
02:57	andyfingerhut	Has anyone created a lein2 project.clj file for one of the new contrib modules, e.g. java.jdbc?
02:57	mk	most of the people who don't seem to be sticking around seem to be coming from perl, C#, ruby, and python
02:58	mk	makes sense that people using perl wouldn't stick around, given clojure's startup time
02:58	seancorfield	mk: what do you mean by "don't seem to be sticking around"?
03:00	unlink	andyfingerhut: not a bad idea at all.
03:00	mk	seancorfield: in the survey, respondents can choose "just starting, weeks, months, 1year, 2, 3, forever" - comparatively fewer people who have been around a long time are coming from the languages I listed
03:00	unlink	andyfingerhut: what I'd really like is (ns some.other.ns) (def ^:private some-var (AClass. (:foo config)))
03:01	seancorfield	mk: hmm, i'm not sure i agree with your take on the data
03:01	mk	this is as a percentage within those groups
03:02	mk	seancorfield: why's that?
03:02	seancorfield	how long they've worked with clojure has nothing to do with "sticking around"
03:02	seancorfield	they could be new to it
03:02	andyfingerhut	I certainly would like it if Clojure had documentation that was more like Perl's. I'm hoping that with the help of enough folks, clojuredocs.org can get there within a few months.
03:03	seancorfield	doesn't mean they've gone away just because they have short experience
03:03	mk	seancorfield: right, but there are new people in all of the languages
03:03	seancorfield	not very many new ppl in lisp or perl :)
03:05	mk	if new people stuck around at the same rate, we would see the same percentage of old perlers as we do CLers
03:05	seancorfield	sorry, i don't follow your logic
03:06	seancorfield	guess i'm not sure what you're trying to prove with the numbers either
03:07	mk	seancorfield: suppose we get 10 perl programmers every year, and 20 java programmers. If we had the same rate of attrition, we would see something like 10 5 2 \| 20 10 4, right?
03:07	seancorfield	ok, i'll play along
03:08	seancorfield	fwiw, i've done both perl and CL in the past...
03:08	mk	now, if perl had a higher rate of attrition, we might see 10 2 0 \| 20 10 4
03:09	mk	and that's what the data actually looks like
03:09	mk	the alternative explanation is that recently, perl programmers in particular became much more attracted to clojure - and I doubt that's the case
03:09	seancorfield	i'm not sure how you can draw historical attrition based on whos
03:09	seancorfield	using clojure
03:10	amalloy	mk: what if the java guys heard of the language when it was new, and the Word of Clojure has only recently spread to perl-land, but they all love it as soon as they see it
03:10	seancorfield	i don't understand how you can draw that conclusion
03:10	amalloy	there are so many different phenomena to explain the data you've indicated so far
03:10	unlink	andyfingerhut: The difficulty is that the initialization is rather particular to the namespace I want to use it in (and thus does not belong in the main method)
03:10	mk	amalloy: yep, that's the other explanation
03:11	amalloy	no, it's not. there are millions of others
03:11	amalloy	maybe perl experts are sick of filling out surveys
03:11	seancorfield	i'm not even sure where you're drawing your past language information from?
03:11	amalloy	probably cemerick's surveys, seancorfield
03:12	mk	amalloy: those explanations become dubious. That they don't like surveys is improbable
03:12	andyfingerhut	unlink: You could make the global var an atom, and modify it. Not necessarily the thing you might want to go for first, but if it is convenient...
03:12	mk	seancorfield: read up :) raw data from cemerick
03:12	seancorfield	i'm looking at that
03:12	amalloy	shrug your own explanations are dubious too. do a real experiment, with a pre-decided hypothesis and a control/test group
03:12	unlink	andyfingerhut: yeah, something like clojure.contrib.singleton.
03:12	seancorfield	not sure how you're drawing conclusions
03:12	amalloy	otherwise you can't really show more than a correlation
03:13	seancorfield	2% perl, 5% common lisp - hardly statistically significan
03:13	amalloy	and even that has a suspect probability. see http://xkcd.com/882/
03:15	mk	amalloy: in that case we should just ignore the survey as a whole. But we don't.
03:15	amalloy	i think we basically do
03:15	seancorfield	mk: i think the point is you're drawing conclusions that are not supportable
03:16	mk	seancorfield: you seem to be disagreeing with the interpretation in general, and not on the basis of numbers
03:16	amalloy	it's useful to see specific complaints/praises from users, which he includes. and it's cool to be like "wow, only 43% of clojure users use emacs (or whatever)", but not very meaningful
03:16	unlink	andyfingerhut: I'm loading a config file with app-global configuration, instantiating a bunch of globals in some other namespace based on that configuration, and then using those globals throughout the course of execution of the program.
03:16	seancorfield	repeat your interpretation and justification... maybe i just missed part of it?
03:17	mk	assuming the numbers hold, which for the sake of a fun chat and blog post, we do...
03:18	seancorfield	are you talking about the 2% perl and 5% CL? those are not statistically significant
03:18	seancorfield	you can't draw any conclusions from that
03:18	andyfingerhut	unlink: Would it change too much to pass that app-global configuration, or some processed version of it, to the functions in that other namespace when you call them? That would eliminate the need for those globals.
03:19	seancorfield	java, python and ruby - those pre-clojure languages are statistically significant
03:19	andyfingerhut	unlink: It could be a single map with arbitrary key/value pairs -- it doesn't need to be a bunch of separate values.
03:19	mk	seancorfield: what numbers are statistically significant?
03:20	seancorfield	mk: you tell me, you're trying to make a point :)
03:20	unlink	andyfingerhut: yes...that's effectively impossible.
03:20	mk	seancorfield: you're rebutting the point on the basis of significance - what do you mean by that? ;)
03:21	seancorfield	mk: i'm trying to understand what numbers you're even talking about...
03:22	mk	the survey numbers. For the sake of significance, look at the language use numbers
03:22	seancorfield	you mean the language previously used
03:22	clojurebot	Excuse me?
03:22	mk	yep
03:22	seancorfield	like i said, anything 5% or below is not statistically significant
03:23	seancorfield	so only java, python and ruby are useful responses
03:23	andyfingerhut	Is there a way to make leiningen (specifically v. 2) have its source files in a deeply nested directory? Like src/main/clojure/clojure/java/jdbc.clj ? And if that is possible, how would I specify that in the project.clj file?
03:23	seancorfield	perl is too low to be useful
03:23	seancorfield	CL is borderline
03:23	mk	seancorfield: what do you mean 5%? if we gathered 99999999 responses, 5% of those in a group would fall under significance?
03:24	llasram	andyfingerhut: Not just :source-paths ?
03:24	unlink	andyfingerhut: :source-paths ["src/main/clojure"]
03:24	llasram	Oh man, I got dynamic reloading of gen-class'ed classes working
03:24	seancorfield	mk: the survey had a much smaller response group - therefore smaller numbers are less significant
03:24	clojurebot	It's greek to me.
03:25	seancorfield	i guess i don't understand why you're fixating on perl when it was only 2% of responses...
03:27	mk	I'm not sure that you're using significance correctly
03:31	mk	in any case, we don't have to worry about this. I was just pointing out a few things about the data that I found interesting - we both know it's not a rigorous survey
03:32	seancorfield	i guess i just don't feel the numbers are big enough to be able to draw those conclusions...
03:33	seancorfield	but those numbers are small enough it doesn't matter anyway
03:33	mk	seancorfield: sometimes numbers can be quite small. Many of the most important experiments in psychology used rather small sample sizes.
03:34	seancorfield	so i guess you can draw whatever conclusions you want :)
03:35	seancorfield	laters
03:35	mk	"most of the perl people who responded are newer" isn't really a conclusion
03:38	unlink	andyfingerhut: I think (delay) is what I wanted.
03:39	andyfingerhut	unlink: Cool. Sorry if I haven't been forthcoming with more ideas. Trying to futz with something that is confusing me.
03:40	amalloy	btw andyfingerhut, thanks a lot for the work you're doing with jira patches. i really hope it helps speed acceptance of these patches (has it already?)
03:41	andyfingerhut	amalloy: Hard for me to tell. Several docstring patches went in pretty quickly after I published my first list. It seems they want to release 1.4 soonish, and so not put in lots of big changes until after that.
03:41	Raynes	Sad.
03:42	Raynes	amalloy: We're gonna have to use 1.6 to get all the good stuff.
03:42	andyfingerhut	Raynes: That more patches aren't going in faster? It would be nice, I suppose, but I can wait until after 1.4 is out the door, if that is their preference.
03:43	andyfingerhut	Raynes: Or github.com/jafingerhut/clojure-build :-)
03:44	Raynes	Yeah, amalloy was drooling over that last night.
03:48	amalloy	i'm a confirmed drooler
03:50	muhoo	how would i add a dependency in lein 1.7, so that it only gets loaded when i'm in a repl, and is not a part of the project, and doesn't get run on other targets like lein run, lein jar, etc?
03:50	andyfingerhut	If you've got any favorite patches you'd like to add to it, you can add another one to the list, run the build.sh script, and see if it applies and builds.
03:50	amalloy	nah, you've already applied all of my patches. mostly i'm just sad that my patches never get applied to clojure
03:51	amalloy	since they're addressing problems i actually encounter
03:51	andyfingerhut	Do you apply them to your own local copy of clojure.core that you use yourself?
04:15	amalloy	andyfingerhut: no. we're actually on 1.3 pure now, sorta teetering on the edge of adopting a 1.4 rc
04:15	andyfingerhut	amalloy: Out of curiosity, are there operational difficulties with using a patched version of Clojure in your dev or deployment environment?
04:16	amalloy	nah, for a long time we used a version of 1.2.0 patched to deal with some issues there
04:17	andyfingerhut	I suppose for some problems, it is easier to work around them in the layer above.
04:31	muhoo	sorry for interrupting with what is probably an intensely stupid question: but how would i, from the repl, instantiate a java class that was defined through (ns foo (:gen-class... :state state...)), such from within functions in the class, calls to (.state this) don't die?
04:32	muhoo	or is the only way to use the class to compile it to a jar, and then load the jar from a different repl?
04:34	llasram	muhoo: Basically, although you don't need to be quite as extreme. Unless you hack around it, gen-class and (ns .. (:gen-class)) just write out class files, which get loaded by the default application class-loader, and thus no reloading
04:35	llasram	Using lein, you should be able to "just" recompile then restart your repl
04:35	muhoo	thanks. and there's no way to do that from the repl i guess?
04:36	muhoo	restarting the repl makes me sad
04:36	llasram	You'll have to restart the once, but if you're feeling brave, I actually spent the evening trying to understand how to get dynamic reloading of gen-class classes to work :-) I'll refheap something in just a sec
04:36	muhoo	that'd be very interesting, thanks!
04:39	Lajla	amalloy, what is your most valued opinion on ##(symbol? (symbol "amalloy, what is your most valued opinion on ##(symbol? (symbol \"I worship his shadow\"))?"))?
04:40	amalloy	like i said, read one of the mailing list threads or stackoverflow questions. it's not considered a problem that not every object can be round-tripped through the reader
04:42	llasram	muhoo: This is working for me: https://refheap.com/paste/1676
04:43	llasram	muhoo: Doesn't interface with (ns .. (:gen-class)), but calling gen-class-reloadable instead of gen-class should give the same sort of class reloading on redefinition behavior as deftype
04:43	muhoo	great, thanks!
04:43	muhoo	i suppose life would be better if i were using defrecord/deftype
04:46	llasram	I think I could use only deftype if there were a way to specify other constructors for deftype'd classes
04:46	llasram	But, alas
04:52	llasram	muhoo: And, you do need to re-`import` the class to get the new version. That should probably go in the gen-class-reloadable macro
04:53	muhoo	hmm, i think something more fundamental is wrong with what i'm doing though. (foo.Bar.) fails NO_SOURCE_PATH, but (foo.Bar/-init) works just fine
04:54	llasram	NO_SOURCE_PATH potentially just refers to the REPL-entered code ?
04:54	muhoo	i'm reloading the source from a file
04:54	muhoo	require'd
04:54	llasram	Hmm. Odd then
04:54	llasram	You might still have old AOTed code sitting around?
04:55	muhoo	ah! i do
04:55	muhoo	i have the project.clj with :aot
04:56	muhoo	but looking around, there are no .class$blahablah files around
04:57	llasram	Hmm. No further ideas here, I'm afraid
04:58	muhoo	that's ok, thanks for that refheap though
04:59	llasram	np. Literally just got that working like an hour ago, so might still have some unintended consequences
05:00	muhoo	it was me, i backed out my recent changes, and i done did somethign stupid. my guess is, not correctly specifying the constructors
05:01	llasram	I'm trying to make a nicer `gen-class' for those of us stuck using it. Providing a syntax and some semantics closer to `deftype`, but still using `gen-class` under the hood
05:01	muhoo	it's a persistentarraymap, but i'm not quite sure of what-all is supposed to go in it
05:02	llasram	Persistents
05:04	muhoo	well yes, but it wants the signature of constructor arguments in a particular order, and i botched that, looking it up now.
05:24	laurus	When I run "lein repl" in Debian Wheezy I get "Unrecognized option: -client. Could not create the Java Virtual Machine." What should I do?
05:27	clgv	laurus: you should provide more information: java version, leiningen version
05:28	laurus	clgv, thanks. Leiningen version is 1.7.0-1, Java version is java version "1.6.0_24", OpenJDK Runtime Environment (IcedTea6 1.11.1) (6b24-1.11.1-3), OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode).
05:29	clgv	laurus: the sun 1.6 jvm has the "-client" option but ignores it in the 64bit version
05:30	laurus	clgv, oh. What should I do then?
05:30	clgv	laurus: you can remove the "-client" option in the "lein" bash script
05:31	laurus	clgv, ok. I guess this is a bug, right?
05:31	clgv	laurus: yeah. a report on github would be great.
05:31	laurus	clgv, do I have to have an account on github to file the bug?
05:32	clgv	I think leiningen might not have been tested with IcedTea6
05:32	clgv	hmm good question. try. if you dont succeed I can post it
05:33	laurus	OK! By the way, the line is "-client $LEIN_JVM_OPTS". Is it okay to comment out the whole line?
05:33	clgv	nope, just remove the -client
05:34	laurus	OK, now I get:
05:34	laurus	/usr/bin/lein: Line 124: -XX:+TieredCompilation: Command not found.
05:35	clgv	gotta go to lunch now, but I'll be back later
05:35	laurus	OK! Thanks!
05:42	muhoo	i'm definitely going to need lein profiles. when at the repl, i don't want aot. when i'm making a jar, i need aot.
05:51	laurus	Does Clojure 1.3
05:51	laurus	Sorry, does Clojure 1.3 work with Java version 7?
06:10	clgv	laurus: yes, that should work
06:11	clgv	laurus: did you just delete the "-client"?
06:16	amalloy	lein definitely works on icedtea6
06:16	laurus	clgv, actually, I completely uninstalled Java, and then only installed openjdk-7-jdk, and then downloaded lein and it worked.
06:16	laurus	So the bug must be in the way Debian set up all that stuff.
06:17	clgv	ok
06:17	amalloy	maybe, but i've installed java/lein on four ubuntu machines without this trouble
06:17	laurus	It pulled in a lot of dependencies, such as gcj, for some odd reason.
06:18	laurus	amalloy, well I am on Debian Wheezy, maybe that is the problem
06:18	amalloy	could be. gcj is definitely certifiably insane
06:18	amalloy	i think a lot of package managers pull that in as "recommended", though who on earth would recommend it for any reason is beyond me
06:18	laurus	I think it was doing something with gcj, even though I couldn't figure out how it was accessing gcj
06:18	laurus	But that's only a hunch.
06:28	clgv	is there a semantic for telling a 'future that a call will block. for agents there is something like that
06:47	muhoo	realized?
06:47	muhoo	&(doc realized?)
06:47	lazybot	⇒ "([x]); Returns true if a value has been produced for a promise, delay, future or lazy sequence."
06:51	clgv	no. the problem is that the code within the future blocks since it's calling a program via clojure.java.shell/sh and waits for the result. I need to limit the number of calls.
06:52	clgv	*the number of concurrent calls
07:03	muhoo	so, a future of a future?
07:04	clgv	muhoo: not really, just a limited threadpool where each thread must keep his future even if it is evaluation is blocking.
07:19	laurus	How do I install the latest version of a package in Leiningen.
07:19	laurus	?
07:19	laurus	And on a related note, how do I find out what the latest version of a package is?
07:20	clgv	laurus: if you really want that you can use something like this: "[0.0.1,)"
07:20	laurus	clgv, thanks.
07:20	clgv	laurus: there is "lein search"
07:20	laurus	clgv, thanks!
07:23	laurus	Is there any faster way? It's taking forever.
07:24	clgv	you can search clojars.org (mainly clojure) or search.maven.org (java)
07:25	laurus	Thanks, that did the trick.
07:26	emcken	I created a jar using "lein jar" and put it in a local maven repo. When I run "lein deps" it only fetches my jar and not the dependencies of the jar... what could I missing?
07:28	clgv	emcken: do you have the dependencies enlisted in your project.clj?
07:29	clgv	emcken: did you use "lein install" to put it in the local maven repo?
07:30	emcken	I only have the dependency of the jar in my project.clj
07:31	clgv	I meant the dependencies of the dependency-jar you were talking about
07:33	emcken	clgv: yes... I've git cloned an existing project and updated a single version dependency and build the jar with "lein jar"
07:33	clgv	emcken: ok. and then you used "lein install" to get the jar into the local maven repo?
07:34	muhoo	i figured out a cheap way around having to compile all time when doing java stuff: i can just make a proxy and redefine the method in the repl
07:34	emcken	clgv: No I used "lein localrepo" to put the jar in a local repository... I'll take a look at lein install
07:35	clgv	emcken: maybe we talk about different "local repos" otherwise "lein install" should be fine
07:37	emcken	clgv: The jar on clojar wasn't new enough... so I build my own jar. But when I try using my own jar it doesn't automatically download all the dependencies of the jar. If I use the older version of the jar from clojar it does... I just don't understand hy there is a difference
07:38	clgv	emcken: that should work with "lein install"
07:41	emcken	clgv: thanks mate... awesome :D
09:06	Gregorius	hello all, may I ask a complete newbe question?
09:07	sattvik	Gregorius: sure
09:08	Gregorius	is clojure a good start to lern programming?
09:08	Gregorius	s/lern/learn/
09:11	sattvik	Gregorius: That's a very interesting question. I am not sure what makes a programming language particular beginner-friendly. I think Clojure is a fine language, but what do you hope to be able to do?
09:12	sattvik	Some languages are better suited to some tasks than others.
09:13	clgv	Gregorius: thats a good question - with my background I say no
09:13	hoeck	Gregorius: what will make clojure harder to learn than other languages is that there are not so many materials for beginners, most stuff assumes prior programming knowledge
09:13	llasram	Gregorius: I personally don't think it's a good first language. The language is great, but the implementation has a lot of rough edges to run into.
09:13	Gregorius	sattvik: I'm not sure what I"d like to do.. just have fun with programming. learn something. Maybe some math with clojure? have no clear vision
09:14	clgv	Gregorius: I would start with an imperative + OO language and a good book on it and then continue to functional languages
09:15	Gregorius	hoeck: http://blackstag.com/blog.posting?id=5 seems be a good start for a newbe
09:15	hoeck	Gregorius: indeed
09:15	Gregorius	clgv: imperative? just like pascal or something like that? becaus all newer languages are mixed paradigm
09:16	clgv	Grgorius: I did learn programming basics in Pacal in school, after that OOP with Delphi, then C++. Java at University. Clojure 2 years ago. ;)
09:17	Gregorius	an why not to start with functional (is clojure functional or mixed paradigm ?). A very thirs high level programming language was functional (it was Plankalkuel designed by Konrad Zuse)
09:17	hoeck	clojure should be way easier to learn than Pascal :)
09:17	jkkramer	Gregorius: the most important thing for a beginner is to be interested and have fun. if you find Clojure to be fun and interesting, I say go for it.
09:17	Gregorius	clgv: java has a much too large APi and many frameworks that I'm not able to look thru...
09:18	clgv	Gregorius: you dont know any programming language, yet?
09:18	Gregorius	hoeck: i was starting about 20 years ago with basic (on ZX81) and later with Turbo Pascal.. but it so long time ago
09:19	Gregorius	clgv: define "knowing programming language" .. I was trying a lot some time ago, a long time ago
09:19	hoeck	Gregorius: so you already have some programming background :) then go with clojure, it has a REPL, instant feedback
09:19	clgv	Gregorius: ah, so you have programming knowlege - well than start with clojure right away ;)
09:19	clgv	*then
09:20	Gregorius	thanx for encurage
09:20	sattvik	Gregorius: That web page isn't too bad. Just browsing over that page, it isn't too bad. The only comment I have is that it might be easier to get started by installing Leiningen and using 'lein repl'.
09:20	Gregorius	so I assume that i may ask really silly questions here?
09:20	hoeck	even with say python you will relatively fast find some rough edges, which are hard to resolve without further knowledge
09:21	hoeck	Gregorius: of course, and never ask to ask, just ask
09:21	hoeck	Gregorius: sometimes it takes a while for someone to pick up your question though
09:21	Gregorius	hoeck: this is clear for me.
09:21	clgv	Gregorius: I suggest you get one of the introductory books about Clojure - that will speed up your learning.
09:22	dgrnbrg	technomancy:
09:22	llasram	Gregorius: +1 on lein if you do give Clojure a go. Also http://clojuredocs.org/ > than the official on-line API docs
09:22	Gregorius	clgv: which one you recommend?
09:22	dgrnbrg	technomancy: any plans to release a new minor of radagast w/ the 1.3 changes merge in on clojars?
09:23	clgv	Gregorius: I read "Programming Clojure" and later "Joy of Clojure"
09:23	Gregorius	clgv: thnx
09:23	fdaoud	Gregorius: for what it's worth, based on books I see being published, Python is also a good choice for a first language.
09:24	Gregorius	python has problems after upgrading from v2 to v3
09:24	fdaoud	Gregorius: what do you mean? If you are just starting out, wouldn't you just be using the latest version? Suddenly you're upgrading programs? :D
09:25	Gregorius	just mentioned a problem if u are using python scripts
09:26	fdaoud	Gregorius: if you say so. no problem. I have no stake in Python myself, just mentioning the trend I've noticed in programming books.
09:27	fdaoud	Gregorius: there is an upcoming Clojure book for beginners, "Meet Clojure" http://meetclj.raynes.me/ but it's not finished yet.
09:28	Gregorius	BTW, i find http://dev.clojure.org/display/doc/Getting+Started better than http://clojure.org/getting_started
09:28	cemerick	Gregorius: There's also the O'Reilly option: http://clojurebook.com
09:28	Gregorius	and beside the google group is there any clojure web forum?
09:32	bradwright	Gregorius: just an aside, as a Python programmer the P3/P2 thing is a red herring
09:32	bradwright	You'll get by fine just learning 2.7
09:32	Gregorius	bradwright: thnx
09:33	bradwright	But obviously you should learn Clojure, as I am (even though I'm a professional Python programmer)
09:33	bradwright	:)
09:33	fdaoud	cemerick: it's April! I hope to receive your book this month :-)
09:34	cemerick	fdaoud: I have assurances that you shall. :-)
09:36	jtoy	which clojure web framework is most like sinatra?
09:36	jtoy	i want to use a simple web framework
09:37	fdaoud	jtoy: probably Compojure
09:37	jtoy	thx
10:20	jtoy	are clojure regex as fast as javas? javas are fast, but reading around i saw that clojure's are slow
10:20	llasram	jtoy: Er? Clojure's regexps are Java's :-)
10:20	llasram	jtoy: But Java's actually are kind of slow vs e.g. GNU libc POSIX regexps
10:21	llasram	Probably not enough to matter for most uses though
10:22	jtoy	I'm regex against a 6 gig file, I'll test it out
10:23	dgrnbrg	Is there a way to have the #WARNING when symbols from clojure.core get overridden be suppressed? I'm writing a replacement core library, and the standard usage scenario is to :use the replacement and :refer-clojure into the clj/ ns.
10:23	llasram	Oh, in that case I/O is almost certainly going to be your bottleneck. The only time I've ever noticed the Java vs GNU libc regexp difference was as a step in a CPU-bound Hadoop job.
10:24	goodieboy	this might sound crazy, but... is it possible to start swank separately and point to an already running clojure app?
10:25	llasram	goodieboy: Not quite, but close-ish. https://github.com/technomancy/swank-clojure -> "Embedding" section
10:27	goodieboy	llasram: ahh ok. yeah that's what we normally do but we deployed the app with config settings that prevented swank from starting up
10:34	TimMc	llasram: Depends on the complexity of the regex, I'm sure.
10:36	llasram	TimMc: That's what I would have thought too, but this was a simple rooted prefix match of the union of a handful of static patterns
10:37	jtoy	im a clojure newb having a hard time trying to figure out how I would take a file and grep for a pattern and stop immediteatly after i found the first line that didn't match after finding matches
10:38	TimMc	jtoy: Will each match be constrained to a single line?
10:38	jtoy	TimMc: yes
10:39	jtoy	i know how to do that with side effects languages, in ruby; found_matches= false;matches = []; while(l=read_file); if matched; found_matches << l; eslif !match && found_matches == true; break; end
10:39	TimMc	Some assembly required.
10:39	TimMc	(but not of the MIPS variety)
10:40	jtoy	TimMc: what do you mean by a box?
10:40	TimMc	a toolbox. :-)
10:40	jtoy	ah ok
10:40	TimMc	jtoy: A reasonable solution might look something like (first (remove #(not (re-match #"stuff" %)) (line-seq ...)))
10:41	TimMc	err, either take out that (not ) or change remove to filter
10:43	TimMc	jtoy: And of course, re-find may be more appropriate than re-match, depending on your regex
10:43	clojurebot	It's greek to me.
10:43	TimMc	clojurebot: That's because you're a bot.
10:43	clojurebot	excusez-moi
10:44	jtoy	TimMc: my regex is just ^RANDOM_INTEGER[[:space]]
10:46	Borkdude	I've got a question. I'm running a noir project from Eclipse, but some css file cannot be found. Where do I place it/what settings do I need to change?
10:57	si14	how can I deal with "Uncaught TypeError: Object function (a,b){return new e.fn.init(a,b,h)} has no method 'U'" error when using :advanced optimization?
10:57	si14	it doesn't show up when I use :whitespace one
10:58	dnolen	si14: hmm, those kinds of bugs are tricky, I haven't actually encountered that one myself.
10:58	si14	dnolen: yeah.
10:58	dnolen	si14: you could emit the source map and use Google Chrome to pinpoint the location.
10:58	si14	dnolen: how can I do this?
10:59	dnolen	si14: download a nightly build of Chrome
10:59	si14	maybe I can tell ClosureCompiler to not optimize jQuery calls?
10:59	dnolen	si14: oh that's you problem right there.
10:59	dnolen	si14: you need to provide the jQuery externs file as part of the build process.
11:00	si14	dnolen: how can I do this?
11:00	dnolen	si14: what are you using to build?
11:00	clgv	si14: ibdknox uses jquery in one of his libraries
11:00	si14	dnolen: cljsbuild
11:00	si14	clgv: I'm using jayq in fact
11:00	clgv	ah lol k ;)
11:01	hhutch	Gregorius: are you still around?
11:01	dnolen	si14: this looks like exactly what you want, http://corfield.org/blog/post.cfm/getting-started-with-clojurescript-and-jquery-and-fw-1
11:03	si14	dnolen: works like a charm. Thanks a lot!
11:24	dentrado	Hello!
11:24	dentrado	If I print (cljs.compiler/emits (cljs.compiler/analyze env form)) and form is a string, number or something else that does not translate to a function-call nothing is returned
11:26	Zoka	Borkdude: Just place the CSS file in your-project/resources/public/css and refer to it as /css/yourfile.css from your html
11:26	dentrado	And (do (+ 1 1) "string") returns just (1 + 1); So only things that translates to function-calls remains. Is there a way around this?
11:26	Borkdude	Zoka: did that
11:26	Borkdude	Zoka: but I get a 404 on that
11:31	jtoy	is there a built in system command to run a command and get its output? the examples i saw all use java
11:33	Zoka	Borkdude: Here is my Noir 1.2.2 project: https://github.com/zoka/noirMon, maybe you can compare and find the cause for your problem
11:33	TimMc	jtoy: A shell command?
11:33	jtoy	yeah
11:33	Borkdude	Zoka: with a lein project it works, but I'm trying to run it as an Eclipse project
11:34	clgv	jtoy: clojure.java.shell/sh
11:34	Zoka	I see,
11:35	Zoka	Have a look at:http://groups.google.com/group/clojuredev-users/browse_thread/thread/d89c1e0da55bb7a5
11:35	TimMc	jtoy: There's another lib floating around that will give you streams instead of strings.
11:35	dentrado	I solved my problem, I had to change :context from :statement to :expr in the env-map to get the returnvalue
11:35	jtoy	cool, thanks
11:36	TimMc	dentrado: Ah, interesting.
11:37	dnolen	dentrado: what are you trying to do?
11:43	dentrado	I'm trying to make a clojurescript repl
11:44	dnolen	dentrado: cool, targeting what?
11:47	halarnold2000	I have a question that was asked of me, from someone even newer to Clojure than I, that I couldn't answer. He was worried about vars being 'mutatable' and showed me an example where he def'd a var (def foo "foo") then in the -main (he jar'd it up to make his point), he has another (def foo (read-line)) that allows one to reassign the var. Aside from being horrible practice, it does seem to be worrisome. An odd contrived example, but it stu
11:48	drewr	halarnold2000: the thing that foo pointed to before is still there
11:48	dentrado	dnolen: I have modified Chris Grangers live-cljs
11:48	dnolen	dentrado: neat!
11:48	drewr	halarnold2000: you can't mutate actual objects, but you can change the names of things (what he did when he assigned foo to something else)
11:49	drewr	well, I shouldn't say you can't mutate anything, because clojure doesn't prevent you from being able to do it
11:49	dnolen	halarnold2000: vars aren't meant to be redef'ed outside of dev.
11:49	drewr	that too ^^
11:50	dentrado	dnolen: at the moment it can display ordinary clojurescript data and if a HTMLElement or a jQuery object is returned it is appended to the repl-output div
11:50	dnolen	halarnold2000: if vars weren't redef'able during dev - Clojure would be a pretty miserable Lisp.
11:50	halarnold2000	dnolen: why would doing a redifining of the var be useful the way he did it?
11:50	dnolen	halarnold2000: I didn't say it was useful.
11:51	dnolen	halarnold2000: I mean redef'ing during interactive development
11:51	halarnold2000	dnolen: I guess I'm missing something (or alot)
11:51	halarnold2000	dnolen: you mean at the repl..
11:52	TimMc	halarnold2000: Yes, at the REPL it is quite common to keep popping in a new version of a defn until it works.
11:52	halarnold2000	TimMc: that makes complete sense
11:52	dnolen	halarnold2000: people generally develop Clojure code interactively, unlike Java which doesn't allow for that really.
11:54	halarnold2000	dnolen: so I get that. Aside from being poor practice, is there any real difference between doing a redefine using a new (def x "foo") and the alter-root? In what it does?
11:54	halarnold2000	under the covers?
11:55	dnolen	halarnold2000: can't say haven't looked closely at the implementation.
11:58	eggsby	the example for alter-var-root looks like its intention is more to wrap existing fns than to just reassign scalars (though I guess it could be used for the latter)
11:59	pyr	the conj! and disj! functions that transients operate on
11:59	pyr	do they come from an interface i can implement for an arbitrary type ?
12:00	TimMc	&(ancestors (class (transient [1 2 3])))
12:00	lazybot	⇒ #{java.lang.Object clojure.lang.Counted clojure.lang.ITransientVector clojure.lang.ITransientCollection clojure.lang.IFn clojure.lang.Indexed clojure.lang.AFn clojure.lang.ILookup clojure.lang.ITransientAssociative java.util.concurrent.Callable java.lang.Runnable}
12:01	TimMc	pyr: Looks like it ^
12:01	jtoy	silly question, why doesn't this line return: (println (clojure.string/join '("grep -E '^" 123 "[[:space::]]' /tmp/testfile")) it just freezes
12:01	pyr	TimMc: 'k thx
12:02	sattvik	pyr: Well conj! relies on clojure.lang.ITransientCollection, disj! relies on clojure.lang.ITransientSet
12:02	TimMc	pyr: There's another interface for things that know how to produce transients.
12:03	sattvik	jtoy: missing a final )?
12:04	TimMc	jtoy: That's not a safe way to build a shell command, by the way.
12:04	pyr	great
12:05	pyr	it wouldn't be ugly if an interface to a disk backed queue i have implemented those, right
12:07	jtoy	parenthesis once again!
12:08	sattvik	pyr: Why would you want to do that? Do you want to be able to use conj! and disj! to indicate mutation?
12:08	pyr	sattvik: or assoc! dissoc!
12:09	pyr	&(ancestors (class (transient {:a :b})))
12:09	lazybot	⇒ #{java.lang.Object clojure.lang.Counted clojure.lang.ITransientMap clojure.lang.ITransientCollection clojure.lang.IFn clojure.lang.ATransientMap clojure.lang.AFn clojure.lang.ILookup clojure.lang.ITransientAssociative java.util.concurrent.Callable java.lang.Runnable}
12:11	eggsby	if you def over an existing def, since the original is still there, how can it be accessed?
12:12	sattvik	pyr: Hmm… For that case, I would probably be tempted to just create new vars in a separate namespace. The ones in clojure.core are transient-specific.
12:13	jtoy	what kind of shell do I get? : (clojure.java.shell/sh "echo $PATH") => IOException java.io.IOException: error=2, No such file or directory java.lang.UNIXProcess.<init> (UNIXProcess.java:148)
12:14	sattvik	eggsby: What do you mean?
12:15	Zoka	eggsby: it will be lost unless you remember its reference in another var
12:17	TimMc	jtoy: Look at the examples here: http://clojuredocs.org/clojure_core/clojure.java.shell/sh
12:18	achin_	I'm trying to use lein2 to build a Compujure/ring app. I need servlet-api.jar in order to build my war, but I need to exclude it in the war itself. Any idea how to do this?
12:18	TimMc	jtoy: Did you give up on line-seq?
12:18	jtoy	TimMc: yeah, I'm too much of a clojure newb, so I'm putting up an easier version for now ,and i will fix it with my better version later
12:19	TimMc	I guarantee this is not going to be easier.
12:19	logicus	is there a way to do what i am trying to do here(at the end) without binding (rest l) and (first l) with let first : http://pastebin.com/xCFXmEED
12:19	jtoy	TimMc: grep is pretty easy :)
12:19	eggsby	thanks Zoka
12:19	jtoy	but yeah, i know
12:19	TimMc	jtoy: But the plumbing is not.
12:20	jtoy	I see, thats funny, every argument news to be cut up, what the point of that?
12:21	S11001001	because shell injection is like sql injection
12:22	TimMc	jtoy: The shell's job is to tear a single string apart and feed it in as separate arguments. Why require that round-trip?
12:23	jtoy	TimMc: i didn't know that
12:23	S11001001	and TimMc is right, the version with that toolbox will be easier and shorter
12:23	TimMc	(This was a big epiphany for me when I first used shell-out commands in Java or Python or something.)
12:23	jtoy	does that mean every space
12:23	S11001001	also variables
12:23	S11001001	quoting characters
12:23	S11001001	process substitution
12:23	jtoy	S11001001: I know its better, Its not easier for me though, I'm still learning clojure
12:23	S11001001	shell interpretation is supermagic and usually not what you want when just creating processes
12:24	S11001001	heh
12:24	technomancy	dgrnbrg: I can push out a new release; sure
12:25	x891	logicus: (take (count l) (rest (cycle l)))
12:27	TimMc	logicus: Or you can look for a lib that has a rotate fn.
12:45	eggsby	does anyone know why I might get a 'No implementation of method: :make-reader of protocol: #'clojure.java.io/IOFactory found for class: nil' when doing a 'lein run' ?
12:45	eggsby	No other errors or context from the stacktrace...

12:51	mk	eggsby: unsure, but since it seems to be a nullpointer on something that it's trying to read, are you sure you have all files in place, and all commands pointing to those files in place also?
12:52	eggsby	I misread the stack trace, it was coming from a file but the file is where it says it is :/
12:54	eggsby	mk: It was my mistake, the file it was trying to read wasn't on the classpath.
12:54	eggsby	Curiously, the project root isnt in the classpath by default?

13:01	hhutch	Licenser: thanks! :)
13:18	dgrnbrg	technomancy: that'd be awesome--I really want to use radagast in my 1.3 projects, but I'm not comfortable w/ leiningen packaging. Is there a resource that explains lein's internals
13:18	dgrnbrg	?
13:21	technomancy	dgrnbrg: there's the plugin guide in the doc directory and the leiningen-core reference docs at http://leiningen.org/reference.html
13:22	technomancy	leiningen internals don't have much to do with using radagast in your own project though
13:22	dgrnbrg	technomancy: cool, i've not seen that page!
13:22	technomancy	unless your project uses lein2; you'd need to update the plugin for that
13:24	technomancy	also radagast is extremely simplistic and may not be practical for real-world projects
13:24	dgrnbrg	I just want rough test coverage help
13:25	dgrnbrg	better than no metrics, anyway
13:25	dgrnbrg	I'm writing a new implementation of much of the core library
13:25	dgrnbrg	to be synthesizable to FPGAs
13:25	technomancy	cool
13:25	technomancy	it might also be useful for finding dead code
13:26	dgrnbrg	how did you get that literate documentation style?
13:26	technomancy	that's from marginalia
13:27	technomancy	it's a bit out of date; let me republish
13:31	franks42	technomancy: hi phil, just changed my HD and restored, and now I get this error: ~/Development/Clojure/clj-ns-browser>lein1 deps
13:31	franks42	Exception in thread "main" java.lang.NoSuchMethodError: org.codehaus.plexus.DefaultPlexusContainer.initialize()V (maven.clj:19)
13:31	franks42	at clojure.lang.Compiler$InvokeExpr.eval(Compiler.java:2911)
13:31	franks42	technomancy: ever seen that?
13:34	technomancy	franks42: yeah, I think it's a conflicting version of plexus
13:35	technomancy	I don't think it's possible to run aether in the same process as lein1, for instance
13:37	franks42	technomancy: yup... but it's the (in)famous: i didn't change anything... (except restored my HD...)
13:37	dgrnbrg	Is there a guide for migrating from lein1 to lein2?
13:37	technomancy	it's just a matter of remembering what you forgot that actually did change
13:37	technomancy	clojurebot: upgrading to lein2?
13:37	clojurebot	No entiendo
13:37	technomancy	clojurebot: upgrading to lein2 is easily accomplished by following this handy upgrade guide: https://github.com/technomancy/leiningen/wiki/Upgrading
13:37	clojurebot	Ack. Ack.
13:38	technomancy	dgrnbrg: there ya go
13:39	dgrnbrg	thanks!
13:40	franks42	technomancy: ough... i confess that my short-term memory is not what it used to be... but really, I didn't change anything ;-)
13:51	franks42	technomancy: blew away the ~/.m2/ and "your" ~/.lein/, and now everything works again... should I ask why, or just accept live as is?
13:52	technomancy	hard to say without knowing what was in ~/.lein
13:52	technomancy	must have been a plugin that pulled in an incompatible dependency
13:53	franks42	technomancy: ...but, but... it worked before ;-)
13:53	technomancy	forgive me for being skeptical
13:54	franks42	technomancy: I forgive you - maybe one day I will remember - moving on...
13:54	fdaoud	technomancy: nicely done!
13:54	technomancy	fdaoud: eh?
13:55	fdaoud	technomancy: lein2 upgrade guide, that is
13:55	fdaoud	<-- must remember to give more context!
13:56	technomancy	oh yeah, glad it's helpful
13:57	fliebel	technomancy: I recall reading about something nice about lein2 regarding native dependencies, could that be?
13:57	technomancy	fliebel: nothing new
13:58	technomancy	maybe just that we got it working the same as lein1? =)
13:58	fliebel	technomancy: That could be it. I'm not sure how lein1 works though.
13:58	franks42	is there a standard way to find the version of a namespace at the repl?
13:59	fliebel	(as with a tiger behind glass)
13:59	franks42	the version of the namespace's package is probably more correct
14:00	raek	franks42: namespaces don't usually contain that information
14:00	raek	franks42: maybe you could look at the output from "lein classpath"
14:00	raek	jars earlier in the list have priority, IIRC
14:01	jtoy	TimMc: S11001001 : i think I'm a little closer, kind of stuck: (with-open [is (clojure.java.io/input-stream "/mnt/results")] (first (remove #(not (re-matches (re-pattern (clojure.string/join '("^" id "\\s")) %))) (line-seq is))))
14:01	S11001001	try reader instead of input-stream
14:02	franks42	raek: hmm ... so maybe heuristic parsing of classpath - the pom-info doesn't get added as meta-info ?
14:03	raek	I don't know what pom-info and meta-info is
14:04	TimMc	jtoy: Instead of str/join, use str directly: ##(let [id 567] (str "^" id "\\s"))
14:04	lazybot	⇒ "^567\\s"
14:04	raek	anyway, if you have two different versions of the same library on the classpath you have problems
14:04	TimMc	jtoy: Also, '(foo bar) makes a list of two symbols, 'foo and 'bar
14:04	jtoy	oh
14:05	franks42	raek: sorry for being terse - I believe the pom-file does have that info, and i was wondering whether that info was somehow added to the jvm-image as meta-data to the classes/namespace that were loaded
14:05	TimMc	jtoy: And #(not (...)) should be #(...)
14:05	franks42	or... can you find out what the jar-file was that was used to load the namespace?
14:06	raek	well, namespace names and project names do not have to be the same
14:07	raek	I think clojure works in a more primitive way when a namespace is required
14:07	jtoy	TimMc: I think the logic is not right, if i have a file 0…,1…,1…,2….. and I search for 1, I want the first and second line returned, i want it to stop after its found 1's and where the next line is not 1, i don't want it to parse the whole file because its 6GB
14:07	raek	when foo.bar is required I think it just looks for foo/bar.clj in all the jar files on the classpath in order and picks the first one
14:08	raek	found
14:08	TimMc	jtoy: Not sure if I understood you correctly, but have you seen take-while ?
14:08	franks42	raek: right... and does it maybe record which jar file was used...
14:08	raek	I don't know if the project.clj/pom.xml data gets into the clojure process
14:10	raek	I don't really know what specific question you are looking for the answer to
14:11	raek	if it is "when I call (require 'foo.bar), which foo/bar.clj file ends up being loaded?", then you should be able to find it out with some detective work and "lein classpath"
14:11	S11001001	do clojure.java.io/resource on foo/bar.clj, strip off the non-jar bits, look at the manifest in the jar, should have some data for you
14:12	jtoy	TimMc: I have not, I will look not, but what Im trying to do, I have a 6 GB file where each line begins with an integer and all those integers are grouped together in lines, so i want to grab the group of integers and not sure how to do it in a functional clojure way
14:12	raek	wher "detective work" is "simulate the clojure loaded by opening each jar and look for the file manually"
14:12	S11001001	but if your url processing code breaks, you get to keep both pieces
14:12	jtoy	i will look now
14:12	raek	*loader
14:12	franks42	raek: i'd like to see the version numbers of the namespace associated package
14:12	TimMc	jtoy: Ah, well, you can use partition-by as well.
14:12	raek	wasn't here a dependency tree thingy in lein2?
14:13	TimMc	jtoy: It's lazy, so no worries on the 6GB.
14:13	franks42	right - recently announced - let me take a look - thanks
14:13	TimMc	raek: lein deps :tree I think? Maybe not released yet.
14:13	xeqi	raek: in master, no release yet. there is a lein-deps-tree plugin that works w/ preview2
14:14	jtoy	TimMc: so do you recommend take-while or partition-by or both?
14:14	TimMc	the latter, if you want grouping
14:15	jtoy	TimMc: partition-by looks like it reads through the whole stream, i want to stop as soon as matches appear and then next non match appears
14:16	TimMc	&(first (partition-by #(= % 3) (range)))
14:16	lazybot	⇒ (0 1 2)
14:16	TimMc	It is lazy.
14:20	jtoy	TimMc: ok, I think I see, so I would use seomthing like: (second (partition-by #(re-matches ##(str "^" id "\\s") (line-seq is)))
14:20	lazybot	java.lang.RuntimeException: Unable to resolve symbol: id in this context
14:22	TimMc	jtoy: Get rid of that ##, it's just a bot trigger. You also want re-find, not re-matches.
14:22	TimMc	Hmm... and you still want re-pattern around str
14:23	TimMc	jtoy: Are you just trying to get one, specific group... or do you want multiple groups?
14:24	jtoy	I want 1 group only
14:24	jtoy	TimMc:
14:26	TimMc	(second (partition-by ...)) will fail for the first group.
14:26	jtoy	TimMc: ? What do you mean, if the input is 2, I want all the 2s: 1,1,1,1,1,2,2,2,2,5,5,5
14:27	TimMc	&(second (partition-by #(= % 2) [1 1 1 1 2 2 3 4 5 5]))
14:27	lazybot	⇒ (2 2)
14:28	TimMc	&(second (partition-by #(= % 1) [1 1 1 1 2 2 3 4 5 5]))
14:28	lazybot	⇒ (2 2 3 4 5 5)
14:29	jtoy	TimMc: I don't understand, why does 2 work but not 1? doesn't (= % id) mean where id equals number?
14:30	jtoy	oh, because its at the beginning
14:31	jtoy	hmm, well, there are 1.8 million ids, so I can use 2 since the probability is low that the id will be in beginning 1/1.8M
14:35	TimMc	o\__/o
14:36	jtoy	TimMc: why is that shocking? http://www.urbandictionary.com/define.php?term=o__o
14:38	TimMc	jtoy: http://globalnerdy.com/wordpress/wp-content/uploads/2007/10/john_mccarthy_successories_poster.jpg
14:39	S11001001	&(partition-by identity [1 1 1 1 2 2 3 4 5 5])
14:39	lazybot	⇒ ((1 1 1 1) (2 2) (3) (4) (5 5))
14:39	jtoy	hmm, its a fun exercise, besides, John McCarthy utterly failed to create AI
14:39	llasram	Ouch. That may be a little harsh
14:39	llasram	(TimMc, not jtoy)
14:40	TimMc	llasram: I think it's called for in response to "the probability is low"
14:40	llasram	Well, I'm more interested in asking:
14:41	TimMc	I mean, this isn't machine learning or anything -- there is a clear way to do it right.
14:41	llasram	jtoy: What about the situation makes you rate a solution which will return incorrect results under some circumstances with a more correct solution?
14:41	jtoy	TimMc: why? the call will fail 1/1.8M , I can just add a fake line at the top 69696969969696 and then they all pass
14:42	llasram	s,with,over,
14:42	muhoo	what's the deftype equivalent of the :state thing in gen-class?
14:43	llasram	muhoo: The fields you specify
14:43	jtoy	llasram nothing, of course I like better solutions, that is the solution TimMc showed me and that is what I am using since I'm still learning clojure and not sure how to do it properly
14:44	S11001001	so partition-by doesn't switch on boolean switching, it switches on equality changes. So you can use arbitrary keys, not just truthiness/falsiness
14:44	llasram	muhoo: With the added benefit that the symbols are bound to directly access the instance fields within your type methods :-)
14:44	S11001001	(see my example)
14:44	jtoy	S11001001: yeah, cool, Im trying that
14:45	muhoo	llasram: wow, thanks! that's much easier than trying to get genclass-loadable to work :-)
14:45	jtoy	btw, even though John McCarthy utterly failed, I absolutely believe in his cause and am spending the rest on my life failing on AI too :)
14:46	llasram	muhoo: `deftype` is definitely the way to go when you can use it, but when you can't... Hopefully this evening I'm going to push up a library bundling up the reloadable gen-class and a new `defclass` macro which provides a `deftype`-like interface to gen-class's functionality
14:47	muhoo	llasram: that'd be fantastic. by the way, in what cases would i "can't" use deftype?
14:47	llasram	muhoo: If you need a JVM class constructor with a particular signature. With deftype the only JVM-level constructor you get is one which takes one argument per field
14:48	llasram	Or if you need to extend an existing superclass
14:48	Bronsa	isn't proxy/reify enough for that?
14:48	muhoo	uh-oh
14:49	muhoo	i do need to have a custom constructor, with 3 String arguments
14:49	jtoy	S11001001: I don't believe that works because it has to go through the whole data set?
14:49	llasram	Bronsa: Not if e.g. you need a named class which an existing framework can instantiate via reflection
14:49	TimMc	jtoy: As I showed you, it doesn't/
14:49	jtoy	TimMc: oh, i thought its different with the identify
14:50	llasram	Bronsa: gen-class is definitely at the bottom of the preference-list, but there are still cases where you need it
14:50	Bronsa	yeah
14:50	Bronsa	for exeptions right?
14:50	Bronsa	*exceptions
14:50	muhoo	well, i guess i could create a class with genclass which has the signaure, and then proxy it to put my actual code in?
14:51	TimMc	jtoy: This would not return if partition-by were not lazy: ##(take 2 (partition-by #(= % 3) (range)))
14:51	lazybot	⇒ ((0 1 2) (3))
14:51	llasram	muhoo: You need an actual class constructor, not just a Clojure factory function?
14:51	S11001001	jtoy: partition-by is perfectly lazy. The result is lazy, and the sublists are all lazy too
14:51	muhoo	llasram: i don't know if i could do it that way. i need a class that has a constructor that takes two strings and returns a string.
14:52	TimMc	S11001001: Not the sublists, I think.
14:52	S11001001	TimMc: indeed, the sublists too
14:52	muhoo	and i want to work on it in clojure repl, meaning auto recompilation
14:52	TimMc	oh, my experiment was flawed
14:52	llasram	Bronsa: Hmm. I actually hadn't considered that case, but yeah -- you'd need to use gen-class for new Exception classes you wanted to define w/in Clojure
14:52	muhoo	llasram: so maybe i could do it without genclass?
14:53	TimMc	S11001001: Nah, it's not.
14:53	llasram	muhoo: If you don't need to interface with existing Java code which is expecting to instantiate your class with a particular constructor, you can almost certainly get away with using deftype and providing a Clojure factory function with the interface you need
14:53	TimMc	I wrote a partitioner that is lazy for the sublists because partition-by is not.
14:54	S11001001	ah, it needs the first element
14:54	TimMc	&(first (nth (partition-by #(= % 3) (range)) 2))
14:54	lazybot	Execution Timed Out!
14:54	muhoo	llasram: not in this case. they don't want a factory. they want to be able to go quux = new Foo(bar, baz); .. and i want to create Foo in clojure, not java
14:55	llasram	Well, unless your type has exactly two fields and your constructor just need to set them to the values passed as arguments, then you're stuck with gen-class :-/
14:56	S11001001	TimMc: oh that is unfortunate, it calls seq before the recursive call
14:56	muhoo	fair enough, i'm stuck
14:56	muhoo	llasram: i'm eagerly awaiting that library then :-)
14:57	S11001001	but it should still be an odd stream, which should be good enough for jtoy
14:57	llasram	muhoo: Knowing that I have another potential user already lined up certainly adds motivation!
14:57	TimMc	S11001001: Eh, I didn't quite write a fully lazy partition-by, but this is very similar: https://github.com/timmc/rand/blob/9d20b2cee7d0193ae5ef7be5507e597cf0a517f5/src/rand/core.clj#L24
15:00	muhoo	llasram: thanks! i found reading it to be very instructional, but there's nfw i could have ever written that myself
15:01	muhoo	so thanks for doing that,it'll make life a lot more pleasant in java-land
15:05	autodidakto	cemerick: What up with the most lazy podcast?
15:05	cemerick	autodidakto: how do you mean?
15:06	autodidakto	ah, misread the date... last was march 13. I shan't complain, then
15:07	autodidakto	need... more... clojure... gotta have my fix
15:07	cemerick	ah, desperation for content :-)
15:07	cemerick	I need to figure out what to do with it next.
15:07	autodidakto	and programming it is kind of complicated. much easier to listen to other people talk about programming.. :P
15:07	muhoo	cemerick: also thanks for writing that book. i'm finding it a lot easier to digest than the other one i was reading
15:08	cemerick	muhoo: glad you like it :-)
15:08	autodidakto	cemerick: yeah. you finished the clojure con interviews, right? what next what next
15:08	cemerick	muhoo: feel free to tweet your opinions, etc ;-)
15:08	cemerick	autodidakto: Yeah, the queue is empty at the moment.
15:09	muhoo	ah yes, promotion through twitter, will do
15:09	autodidakto	There's the thinkrelevance podcast which is on a... lazy... schedule as well. The clojure podcasting field is wide open, I tells you, wide open
15:09	muhoo	(doseq lazy-podcast)
15:09	cemerick	really? They've been pumping episodes out pretty rapidly, it seems.
15:10	xeqi	and the screencasting field
15:10	jtoy	S11001001: even with partitioning by identity? what is the proper way to grab the arbitrary id in : (partition-by identity [1 1 1 1 2 2 3 4 5 5]) ?
15:12	autodidakt	oops. bad inet conection
15:13	autodidakt	cemerick: maybe it seems that way to me because the content is just a little inconsistent. half company chatter. i dunno
15:13	cemerick	Sure. It's certainly the Relevance podcast, not a Clojure-only 'cast.
15:14	autodidakt	xeqi: ah good point. technomancy did the peepcode a while back, and there are some outdated stuff on youtube...
15:14	jtoy	&(filter #(contains? % 5) (partition-by identity [1 1 1 1 2 2 3 4 5 5]))
15:14	lazybot	⇒ ()
15:15	autodidakt	cemerick: maybe I need to stop staring at itunes, clicking refresh. Can't wait to see what you come up with, though
15:15	autodidakt	&(doc partition-by)
15:15	lazybot	⇒ "([f coll]); Applies f to each value in coll, splitting it each time f returns a new value. Returns a lazy seq of partitions."
15:16	amalloy	~contains?
15:16	clojurebot	Gabh mo leithscéal?
15:17	amalloy	damn it, who un-taught him that
15:17	amalloy	&(doc contains?)
15:17	lazybot	⇒ "([coll key]); Returns true if key is present in the given collection, otherwise returns false. Note that for numerically indexed collections like vectors and Java arrays, this tests if the numeric key is within the range of indexes. 'contains?' operates constant or... https://refheap.com/paste/1694
15:17	amalloy	&(filter #(some #{5} %) (partition-by identity [1 1 1 1 2 2 3 4 5 5]))
15:17	lazybot	⇒ ((5 5))
15:19	TimMc	contains?
15:19	TimMc	~contains
15:19	clojurebot	Titim gan éirí ort.
15:19	TimMc	Huh, that's annoying.
15:27	amalloy	clojurebot: contains \|is\| <reply>contains? checks whether an indexed collection (set, map, vector) contains an object as a key. to search a sequence for a particular object, use the `some` function, which accepts a predicate. if you want to only match a certain object, you can use a set as the predicate: for example, (some #{5} (range)) finds the first occurrence of 5
15:27	clojurebot	'Sea, mhuise.
15:30	weavejester	Are profiles a Lein2 thing, or are they in 1.7 as well?
15:31	autodidakt	w2
15:31	autodidakt	weavejester: 2 -> https://github.com/technomancy/leiningen/wiki/Upgrading
15:32	Raynes	weavejester: https://github.com/technomancy/lein-profiles
15:32	weavejester	Ah, thanks :)
15:33	Raynes	weavejester: But I highly recommend just upgrading.
15:33	Raynes	All the cool kids are doing it.
15:33	Raynes	Except amalloy, who only appears to be cool.
15:33	weavejester	I've been on Lein2 for ages :)
15:33	Raynes	Oh.
15:33	Raynes	Well, good works ir.
15:33	amalloy	whaaaaat. i use lein2 for the projects that it works for
15:33	weavejester	But I was curious whether I should make a plugin that relies on profiles
15:34	Raynes	amalloy: Yeah, but you're still not cool.
15:34	amalloy	sure
15:34	weavejester	i.e. "lein with-profile headless ring server" instead of "lein ring server-headless"
15:35	weavejester	Where: :profiles {:headless {:ring {:open-browser? false}}}
15:35	weavejester	But I guess I'll wait for Lein2 stable for that.
15:36	muhoo	llasram: if it's going to be on github, is your username there llasram?
15:36	llasram	muhoo: yep
15:36	muhoo	thanks, will check there.
15:37	llasram	cool beans
15:37	xeqi	ohh, then I could just set that in the project
15:37	jtoy	TimMc: so is that the proper way to get my data after partitioning by identity? (filter #(some #{5} %) (partition-by identity [1 1 1 1 2 2 3 4 5 5]))
15:38	jtoy	this just freezes for me:
15:38	jtoy	&(filter #(some #{5} %) (partition-by identity (range)))
15:38	lazybot	Execution Timed Out!
15:40	autodidakto	&(filter #(some #{5} %) (partition-by identity (range 7)))
15:40	lazybot	⇒ ((5))
15:42	dakrone	muhoo: `lein clean, compile, trampoline repl` will run faster
15:43	xeqi	&(first (filter #(some #{5} %) (partition-by identity (range))))
15:43	lazybot	⇒ (5)
15:44	autodidakto	xeqi: ah :)
15:47	muhoo	dakrone: thanks!
15:49	goodieboy	anyone here have any experience with the medusa library?
15:49	goodieboy	or .. java futures?
15:50	technomancy	clojure futures are java futures FWIW
15:50	jtoy	xeqi: nice
15:50	fdaoud	autodidakt: technomancy did a peepcode? where?
15:50	technomancy	clojurebot: peepcode?
15:50	clojurebot	peepcode is a commercial screencast series; see the Clojure one at http://peepcode.com/products/functional-programming-with-clojure by technomancy
15:50	jtoy	the parenthesis are really killing me
15:51	goodieboy	technomancy: ok that's good to know
15:51	fdaoud	technomancy: ah!! yes, I watched that one. Didn't click that it was you :)
15:51	fdaoud	technomancy: I thought it was one of those play-by-play ones. Which are mostly ruby/rails :P
15:52	fdaoud	Raynes: how's the rest level my friend. you starting to refuel?
15:53	technomancy	weavejester, Raynes: the lein-profiles backport to 1.x is fairly out of date FWIW
15:54	fdaoud	lein ring server-headless never seemed to work for me, still opened a browser
15:54	technomancy	considering it doesn't have any watchers (and lein2 adoption has been quicker than expected) I'm not inclined to update it
15:54	TimMc	jtoy: What editor are you using? Both Emacs and vim have paredit packages, which take the pain out of balancing parens.
15:55	weavejester	fdaoud: Someone just fixed a bug in the latest lein-ring that caused lein ring server-headless not to work. When I release 0.6.3, it should fix your problem.
15:55	weavejester	fdaoud: Or if you're using lein2, you could just setup a profile where :open-browser? is false
15:55	jtoy	TimMc: I currently am using sublime text2, I do use vim often too, but I like sublime because it has a clean guy with vim bindings
15:55	fdaoud	weavejester: excellent-- thank you!
15:55	achin	weavejester: Thanks for pulling in the servlet-api.jar fix.
15:55	weavejester	:profiles {:headless {:ring {:open-browser? false}}}
15:56	weavejester	achin: No problem. I'll try and release 0.6.3 soon
15:56	fdaoud	weavejester: I'm trying to write about this stuff but there's a lot to keep up with!
15:56	achin	weavejester: Thanks. That one took me a while to debug. We're testing our wars in Jetty, Tomcat, and JBoss. They all acted differently with servlet-api.jar hanging around.
15:57	weavejester	achin: The patch is much appreciated.
15:57	achin	weavejester: No worries.
15:57	weavejester	Unfortunately, I only use a subset of Lein-Ring's functionality, so I rely on others to fix bugs in the war and uberwar stuff :)
15:58	achin	weavejester: Hehe. We only use a few, too. Uberwar just happens to be one of them.
15:58	weavejester	achin: I'm also just about to send a reply to your other PR
15:59	achin	weavejester: Cool. Thanks.
15:59	weavejester	achin: I'm a little demanding, but I think it'll work better in the way I describe in the comment.
16:00	fdaoud	technomancy: so how did that peepcode thing work out? you provided the content and geoffrey did the voiceover?
16:00	technomancy	fdaoud: yeah, that's correct
16:00	weavejester	achin: I'd suggest creating a leiningen.ring.server.adapter and leiningen.ring.server.uberwar namespace to handle the two cases.
16:01	weavejester	achin: If you like, you can also split it up into two PRs; one for the :web-xml option, the other for the server-uberwar command.
16:02	achin	weavejester: Sure. All of that makes sense. Yeah, that'd be helpful. One of my co-workers created the server-uberwar task. We don't really use it.
16:02	weavejester	achin: Ah, if you don't, then you might want to strip it from the PR. It's the only part I want changed significantly.
16:03	achin	weavejester: Sounds good. Are you okay with me continuing to force push to the branch?
16:03	weavejester	achin: Yep
16:03	achin	weavejester: Thanks.
16:04	jtoy	uh, I think I'm close on this, how do I do nested #'s? (defn mygrep [id] (with-open [is (clojure.java.io/reader "/mnt/results")] (first (filter #(some #(re-find (re-pattern #(str "^" id "\\s")) %) (partition-by identity (line-seq is) ))) ))
16:06	TimMc	fn literals can't nest -- how would they know which level % refers to?
16:06	TimMc	You can use (fn [x] ...) instead.
16:06	jtoy	TimMc: I know, bbut I'm not sure,
16:06	jtoy	oh, ok, more parantheses
16:06	jtoy	:)
16:07	Raynes	fdaoud: Not really.
16:09	fdaoud	Raynes: sorry to hear that. hopefully the summer is good to you.
16:10	jtoy	what is the searchable name for # so i can read about exactly how it works?
16:11	franks42	Raynes: Q about cd-client: seems that I get v1.2 info back instead of the latest and greatest - is that a known issue, or am i doing something wrong?
16:11	technomancy	if anyone's interested in more flexible jar creation in leiningen, check out the last 2 commits or so
16:11	technomancy	interested in feedback
16:12	Raynes	franks42: I'm not the cd-client guy. I've just contributed a bit.
16:12	sattvik	jtoy: #(foo %) essentially expands to (fn [x] (foo x))
16:12	sattvik	jtoy: It's a reader macro.
16:13	franks42	Raynes: sorry - i can see that now - kind of thought you were responsible for most projects here ;-)
16:13	Raynes	Bahahaha
16:13	Raynes	Yeah, Rich Hickey is one of my psudeonyms.
16:13	muhoo	so, just to be completely thick, if i aot recompile a java class, there's no way to refresh it from the repl without restarting the repl?
16:14	sattvik	muhoo: Pretty much, unless you're doing something like running JRebel.
16:15	muhoo	import does not seem to reimport, and there's no :reload flag like with require
16:16	muhoo	ok, i'll wait for gen-class-reloadable then :-) sigh
16:17	autodidakto	Anyone want to refheap their lein2 profiles.clj for me to learn from? I'm having problems formatting the hashes right..
16:19	jtoy	anyone using sublime text with clojure?
16:19	ldopa	muhoo: you can hack it using DynamicClassLoader. I'm definitely not an expert, but I messed around with it based on this thread http://groups.google.com/group/clojure/browse_thread/thread/42ce906da3a3e438
16:21	autodidakto	jtoy: I toyed around with it for a bit. There's syntax highlighting and someone is working on integrating a repl.
16:21	jtoy	autodidakto: perfect, can't wait
16:24	autodidakto	jtoy: the repl is called SublimeREPL. But, in general, there aren't many lisp related tools... no paredit, etc. A shame cuz Sublime is a pleasure to use.
16:24	jtoy	autodidakto: yeah, i know what you mean
16:25	Null-A	paredit is a deal breaker for me
16:25	autodidakto	fdaoud: I had a tough time watching the play-by-plays... half of them spent half the time fighting with their testing framework, it seemed
16:28	fdaoud	autodidakto: I found them mostly painful, as well. glad it's not only me.
16:28	fdaoud	autodidakto: which ones did you watch?
16:29	autodidakto	all at least in part
16:29	Raynes	jtoy, autodidakto: You can use it, but the auto indentation is atrocious. You could fix it yourself if you were willing to edit a couple thousand lines of XML and never actually see your fixes go into Sublime itself.
16:30	mwillhite	hey all, I'm looking at a leiningen project and there is a bootstrap.clj file that I'd like to run, it has a -main defn that sets up my db etc…now for the dumb question…how can I run that file?
16:30	muhoo	how would i coerce a #<ChecksumValidatingInputStream com.amazonaws.services.s3.internal.ChecksumValidatingInputStream@c8c7d6> into a plain old outputstream, or something spit can handle?
16:30	autodidakto	Raynes: sounds like you had a bad experience
16:31	raek	mwillhite: if the file is in src/foo/bar/bootstrap.clj you run "lein run -m foo.bar.bootstrap"
16:31	Raynes	autodidakto: Wrote a whole blog post about it.
16:31	fdaoud	autodidakto: to me, hwang was ok, shaw had some interesting parts. the others, especially patterson, were mostly annoying. just singer I haven't watched yet.
16:31	autodidakto	Raynes: ouch. link me
16:31	jtoy	does anyone see anything wrong about this: (defn mygrep [id] (with-open [is (clojure.java.io/reader "/mnt/results")] (first (filter (id (some (fn [x] (re-find (re-pattern #(str "^" id "\\s")) x)) (partition-by identity (line-seq is) ))))) )) <--- I get ClassCastException java.lang.Long cannot be cast to clojure.lang.IFn user/mygrep (NO_SOURCE_FILE:15)
16:31	mwillhite	ah perfect thanks, I just missing the -m
16:31	jtoy	I can't even read what I wrote :(
16:31	mwillhite	*was just
16:31	scgilardi	(id <-- looks like the culprit
16:32	raek	if that file is declared as :main in the project.clj, you can just run "lein run"
16:32	Raynes	autodidakto: http://blog.raynes.me/blog/2012/02/01/i-code-with-things-and-stuff/ To be fair, most of it was just about Emacs and Vim and me moving there, but there is some stuff about my ST2 experiences.
16:32	jtoy	scgilardi: is that a special var?
16:32	Null-A	I just finished writing a Java compiler in clojure that took 4 months for school
16:32	mwillhite	cool thanks raek
16:32	Null-A	so much fun
16:32	autodidakto	fdaoud: ah yes. hwang made quick progress. lots of talk about modelling your db. shaw wasn't bad either. i'm a fan of patterson, but watching him hack through the tests was painful
16:32	raek	np :)
16:32	scgilardi	no, but it looks like it's bound to a Long at the time of the call
16:32	hiredman	Null-A: very cool
16:32	Null-A	6 thousand lines of clojure :)
16:32	hiredman	Null-A: does it compile the clojure compiler?
16:32	autodidakto	fdaoud: singer is the UI guy, right? yeah that was a nice change of pace. two vids though
16:33	hiredman	:)
16:33	Null-A	hiredman: it's not a full java feature set
16:33	Null-A	but pretty big
16:33	Null-A	the java specs are brutal
16:33	Null-A	too many weird corner cases
16:34	hiredman	yes
16:35	Null-A	I leveraged combinator parsers, core.logic, core.match, wrote some DSLs for working with assembly, tokenizing strings, multimethods of course
16:35	fdaoud	autodidakto: right, singer is two vids, I'll probably watch them soon. patterson was long and full of dead-ends, plus he was swearing (which the peepcode faq says does not occur) and my two young daughters were within earshot so that added to my annoyance.
16:35	Null-A	one of the places where macros really shine is testing support
16:35	Wild_Cat	Null-A: testing support? How so?
16:36	Wild_Cat	(one thing where macros totally make me jealous when writing Python though is logging support -- so much wasted CPU time :p )
16:37	Null-A	Well, when you work with C++ testing libraries
16:37	Null-A	there's usually no way to generate unit tests
16:37	Null-A	I guess you could do it at runtime
16:37	autodidakto	fdaoud: Overall I'm conflicted about the play-by-play format.
16:37	muhoo	spit doesn't take an inputstream, eh?
16:37	jtoy	the parenthesis really are killing me, can you guys recommend some articles that explain how to deal with them?
16:37	fdaoud	fdaoud: did you watch weirich? if so, how is it?
16:38	fdaoud	autodidakto: did you watch weirich? if so, how is it?
16:38	Wild_Cat	Null-A: ah, good point, my reference points are Python and Java, not C++. Whose unit testing libs are, I understand, much less restricted.
16:38	technomancy	jtoy: with paredit the parens just disappear
16:38	autodidakto	fdaoud: the rake guy?
16:38	Null-A	Wild_Cat: nods
16:39	TimMc	jtoy: I told you, paredit.
16:39	fdaoud	autodidakto: yes
16:39	jtoy	how about for vim? also paraedit?
16:39	autodidakto	jtoy: yeah. paredit.vim
16:39	raek	jtoy: show-paren-mode (or equivalent) and an editor that can readjust indentation based on the parens
16:40	muhoo	jtoy: could be worse, you could be writing javascript, and the ends of your functions could look like };)])}};);
16:40	muhoo	try to keep those matched up :-)
16:40	autodidakto	fdaoud: The topic was building a proxy object... but they hit a fat dead end halfway through and he redid it simpler
16:41	jtoy	that is try
16:41	mk	muhoo: easy, all you need is 9 tabs!
16:41	fdaoud	muhoo: that's a funny tower of winking guys with curly hair
16:41	aperiodic	vim users: slimv will change your life
16:41	autodidakto	fdaoud: interesting metaclass things, manipulating what a class called it self to be or some sort, but then they realized that the way they did that would confuse rails
16:41	duck1123`	muhoo: that's why there's ClojureScript
16:41	muhoo	fdaoud: or one very long and verry scragglly neckbeard
16:42	muhoo	duck1123`: amen.
16:42	fdaoud	autodidakto: heh. what doesn't help my interest in the pbp is that I'm not a whole lot into ruby and rails..
16:43	muhoo	ok, inputstreams. do i really need to write a (loop (.read in buffer) blah blah, in order to spit out something from an inputstream, or does spit do it and i'm just being stupid?
16:43	jtoy	aperiodic: is slimv enough or do i need other plguins? slimv seems to include paredit?
16:43	technomancy	muhoo: you can usually use clojure.java.io/copy or slurp
16:43	raek	spit operates on text, so you con't use it for binary streams
16:44	autodidakto	fdaoud: part of the value is supposed to be watching and learning from their process. But in a way, I've learned that great programmers have just as broken half-setups as me, heh
16:44	muhoo	technomancy: as long as it's lazy. i don't want to slurp the whole thing into memory then write it out
16:45	raek	muhoo: what are you doing with the bytes from the input stream?
16:45	technomancy	c.j.io/copy works in chunks
16:45	muhoo	raek: writing them to disk, nothign fancy
16:45	technomancy	though ISTR someone saying it had a bug that may have been related to input-streams
16:45	raek	muhoo: reading from a input-stream and writing to an output-stream?
16:45	aperiodic	jtoy: slimv should be enough. it includes paredit, indentation, syntax highlighing (the latter two from VimClojure)
16:46	jtoy	thx
16:46	muhoo	raek: yeah, and if i can do it without looping, great, if not, no big deal.
16:46	aperiodic	jtoy: you'll want sjl's fork of slimv for clojure https://bitbucket.org/sjl/slimv/src/2537d9e7039c/doc/slimv.txt
16:46	raek	muhoo: then use io/copy
16:46	raek	it does that loop
16:46	muhoo	perfect
16:47	raek	if you give it a file path rather than an open stream, it will open and close it itself
16:47	muhoo	i knew someone had already done it :-)
16:47	muhoo	yep ##(doc copy)
16:47	lazybot	java.lang.RuntimeException: Unable to resolve var: copy in this context
16:47	muhoo	yep ##(doc clojure.java.io/copy)
16:47	lazybot	⇒ "([input output & opts]); Copies input to output. Returns nil or throws IOException. Input may be an InputStream, Reader, File, byte[], or String. Output may be an OutputStream, Writer, or File. Options are key/value pairs and may be one of :buffer-size buffer size ... https://refheap.com/paste/1700
16:47	raek	it won't close a stream that it didn't open
16:47	raek	(so a with-open might be needed)
16:48	muhoo	good point, thanks
16:48	fdaoud	autodidakto: hwang was pretty good. another guy, I forget who, was totally useless. he typed everything the long way. he said he drank beer instead of learning his editor. well, a bit of time learning your editor, you have a lot more time for beer because you're not spending all your time typing every last detail out!
16:49	raek	jtoy: before I started using paredit I usually just selected a block of code and pressed tab to reindent it. any misplaced paren becomes pretty obvious then.
16:49	raek	in emacs, that is
16:51	autodidakto	fdaoud: bahaha. i remember that part... what was he working on, again?
16:51	duck1123`	C-x h <tab> is great for languages that it works in
16:51	muhoo	that was it, thanks!
16:52	jtoy	it seems like its a bunch of plugins , can I just use part of it, I've never used swank
16:53	fdaoud	autodidakto: it was the chat webapp that he called gumflap.
16:53	raek	for editing clojure code in emacs, clojure-mode is the only one you need
16:54	llasram	And maybe clojure-test-mode !
16:54	raek	paredit can be nice too. slime gives you a clojure repl (plus tab completion, and more) - but don't install slime directly
16:54	autodidakto	fdaoud: oh yeah. they actually finished quite quickly. It was a bit of client side js... except the most interesting part, the websockets, they simply used a webservice
16:55	raek	(it's usually simpler to let lein-swank provide the correct slime version via clojure-jack-in)
16:55	aperiodic	jtoy: it is a bit to swallow at once. but it's worth it. what i did was add lein-swank as a dev dependency to my projects, set swank_host and swank_port in my vimrc, started a server with `lein swank`, and then i was up and running
16:55	autodidakto	jtoy: it's going to be annoying to spend most of your programming time, at first, simply getting things working, but tis the life...
16:56	raek	I think it's recommended to install lein-swank as a plugin rather than having it as a dev-dependency
16:56	technomancy	yup
16:56	raek	since lein-swank is for user convenience and does not have anything to do with the project
16:58	aperiodic	oh, ox
16:58	aperiodic	*ok
16:59	jtoy	hmm, one thing it seems to be missing is rainbow parenthesis, isn't that a must have for clojure?
16:59	Raynes	No.
16:59	aperiodic	i don't feel the need, with paredit
16:59	Raynes	The only thing you can consider must-have is paren highlighting. If you put your cursor on a closing paren, it should highlight the opening paren that corresponds with it and vice versa.
16:59	Raynes	And pretty much every editor does that by default.
17:00	muhoo	heh, well i snuck clojure in on this guy after all!
17:00	mk	rainbow parens make it easier to see where all parens end at a glance
17:00	technomancy	rainbow parens make it easier to match up parens
17:00	technomancy	which is bad
17:00	muhoo	i told him i was delivering him a maven project with a pom.xml file (thanks lein) and he got all excited.
17:00	technomancy	because that's not something humans should spend their time doing
17:00	mk	paren highlighting requires you to move your cursor around to do the same thing
17:00	muhoo	and also, i'm writing the junit tests in pure java so his guys have example code to cut and paste
17:01	muhoo	sorry "artifact".
17:01	mk	technomancy: I don't think it's for manually counting parens. It's for seeing where forms and subforms begin and end
17:02	raek	that's usually pretty simple to read from the indentation too
17:02	llasram	I'd kind of like a mode that put a mostly-translucent overlay over the text, colored on a shifting scale by nesting depth
17:02	llasram	It might actually be awful, but in my mind it would make nested code easier to read
17:03	duck1123`	I'm pretty sure someone did that for emacs, IIRC it looked horrible
17:03	llasram	Well, there we go :-)
17:03	ferd	llasram: http://www.emacswiki.org/emacs/HighlightSexps
17:03	raek	llasram: I have seen a mode that painted the parens red with varying saturation depending on depth comparing to the point
17:03	llasram	raek: Potentially close... I'll have to check that out
17:04	TimMc	I think mine does that.
17:04	raek	http://www.emacswiki.org/emacs/HighlightParentheses
17:04	mk	llasram: yes. I assume you're talking about essentially coloring the whole background of forms, instead of just the two parens
17:04	llasram	mk: right
17:04	duck1123`	I remember having that on for 5 minutes or so
17:04	raek	probably that one
17:04	mk	ferd: nice link. It should really highlight that in a box though, without extending left and right
17:05	mk	the corners of the box should be at the while, and that right-bottom paren
17:06	mk	duck1123`: what was bad about it?
17:06	mk	I would guess it was the constant switching, as your cursor moved around
17:06	llasram	mk: Agreed; and that's where -- from what I know of how Emacs text properties and overlays work -- it gets very difficult to implement :-)
17:07	mk	poor emacs :(
17:08	duck1123`	mk: I just found it too distracting. Also, I seem to remember it barfing over my Ruby code, but it's been a while
17:09	ferd	mk: default colors suck. Once you tweak them, it's nice for occasionally showing code to others (a demo maybe?). For regular use, the switching is too much for me
17:10	mk	I think that it's one of those features or tools that is great if implemented very well, but painful if anything falls short...
17:12	ferd	I don't know enough... but some modes in Emacs use rectangular highlights... So, somebody would know how to do it right (given enough time, obviously ;-) )
17:14	autodidakto	technomancy: trying out your starter kit. I got got v24, now I need to add lines to ~/.emacs.d/init.el... I'm assuming I create that myself..
17:14	technomancy	yup
17:15	autodidakto	thanks
17:18	jtoy	cool, paredit seems to work, lets see if i can fix my broken code now
17:20	autodidakto	technomancy: Oh, RET means "hit return here". lol this is gonna be a while... Thanks for the project btw
17:22	clgv	Since caching of the byte[] representation of classes might never be added to Clojure's DynamicClassLoader, is there a way to intercept class definition to enable a custom caching for a library?
17:22	joly	technomancy: yes, much thanks for the emacs starter kit.
17:24	technomancy	glad it's helpful
17:26	muhoo	are there any clojure goodies for generating javadoc?
17:26	jtoy	paraedit doesn't let me delete parenthesis some times it seems?
17:27	sorenmacbeth	technomancy: does lein-swank 1.4.4 include CDT?
17:27	duck1123`	paredit deletes matched parens when they're empty. Sometimes if things get messed up, you need C-w and C-q (
17:28	muhoo	hmm, looks like there aren't.
17:28	technomancy	sorenmacbeth: it should
17:29	sorenmacbeth	a (use 'swank.cdt) give me this: http://pastie.org/private/ybjaqenubcdqmwjckgpq
17:30	raek	jtoy: use M-s to remove a matching pair, for example
17:31	sorenmacbeth	technomancy: tl;dr - it complains that cdt.ui is missing
17:31	raek	there's lots of other commands to
17:31	raek	*too
17:31	jtoy	I'm on vi, are those emacs commands?
17:31	raek	ah, sorry. yes they are
17:31	technomancy	sorenmacbeth: haven't seen that sorry. I'm not familiar with cdt.
17:32	sorenmacbeth	technomancy: me neither, sadly
17:33	sorenmacbeth	technomancy: I don't need to have swank-clojure AND lein-swank installed right? just having lein-swank should include cdt yes?
17:33	jtoy	it seems like i have to think about how i code differently too, normally I would do (foo 123) then surround it with (bar (foo 123)) but paredit doesn't let me do that
17:33	technomancy	sorenmacbeth: it will bring in its own swank-clojure if the project doesn't specify one. it could be it's specifying one that's too old
17:34	jtoy	instead it seems like i have to do bar then foo, so think from the outside in instead of inside out
17:34	duck1123`	jtoy: I don't know vi, but in emacs' paredit M-S-( does what you want
17:34	sorenmacbeth	technomancy: I'll try specifying one and see if that fixes it
17:35	duck1123`	I guess it's really just M-(
17:35	jtoy	duck1123`: do you know what that command is called in general?
17:36	TimMc	jtoy: paredit is a structural editor -- Given \|(foo 123), you might type "(bar" (giving (bar\|)(foo 123)) and then ctrl-right-arrow to slurp the foo sexpr into the bar sexpr.
17:36	autodidakto	jtoy: try the arrow keys to move the ('s
17:36	duck1123`	jtoy: paredit-wrap-round
17:37	amalloy	right. paredit seems, at first, to stop you from doing the "sloppy" stuff you're used to, like typing x, and then a ( and a ) on either side of it, but it actually makes it easier to do them once you learn the command for it
17:38	yoklov	M-(
17:38	yoklov	<3 paredit
17:38	yoklov	i miss it whenever i have to write lisp code outside emacs
17:38	amalloy	like if you have (let [x 1]) x, you "want" to delete the paren and type a new one after x. but paredit doesn't like the in-between broken state, so you use C-) instead to slurp the x into the let
17:38	TimMc	It's like tab-completion, life sucks without it.
17:38	amalloy	which really is much easier, especially if x is some long expression
17:39	muhoo	trying to write lisp without paren matching is like trying to write java without autocomplete
17:39	amalloy	haha
17:39	amalloy	sad but true
17:39	TimMc	exactly
17:39	yoklov	lol, yeah
17:40	jtoy	hmm, maybe i should go sit around and watch some clojure people code, i don't know any
17:40	duck1123`	I hate after merging a conflict when I acidentally delete a bunch of stuff because paredit wasn't turned on
17:41	jtoy	hmm, didn't think about that, merging diffs must be a huge PITA
17:41	aperiodic	jtoy: <leader>-W wraps the form at the cursor in parens
17:41	sorenmacbeth	technomancy: yea, it works if I put swank-clojure 1.4.2
17:41	amalloy	well, paredit turns itself off if you load a broken file
17:41	sorenmacbeth	technomancy: lein-swank is grabbing swank-clojure 1.4.0
17:41	amalloy	so merging diffs works out okay, as long as you turn it back on afterwards
17:42	patchwork	Hey #clojure, I'm upgrading a ring app of mine to the latest 0.6.2 and compojure 1.0.1, but now I am getting an arity exception from wrap-reload? (which I don't even call, but apparently is called through handler/site):
17:42	sorenmacbeth	technomancy: pull request coming..
17:42	jtoy	and what is the "proper way" to thing when coding clojure, in to out or out to in?
17:42	patchwork	Wrong number of args (1) passed to: reload$wrap-reload
17:42	patchwork	I didn't change anything and it worked before
17:42	amalloy	jtoy: either way. whatever makes sense in context
17:42	patchwork	are wrappers handled differently now?
17:42	duck1123`	1) feel like an idiot. 2) C-x C-v <ret>
17:43	aperiodic	jtoy: there's a full list of paredit.vim commands in the docs (https://bitbucket.org/sjl/slimv/src/2537d9e7039c/doc/paredit.txt)
17:44	jtoy	aperiodic: awesome thanks
17:45	sorenmacbeth	technomancy: pull requested
17:45	patchwork	Actually, wrap-reload is not being called anywhere!
17:45	jtoy	so besides the parenthesis issues, can you guys recommend some articles on how to write "proper" code, even without parenthesis, my code is still horrible to parse, should i indent ala python or ?
17:45	amalloy	$google mumble scheme style
17:45	lazybot	[Riastradh's Lisp Style Rules - It works!] http://mumble.net/~campbell/scheme/style.txt
17:45	aperiodic	the ones I find myself using most often are wrap (,W), splice (,S), and slurp left/right (,< and ,>) (assuming <leader> is the default of ',')
17:45	Raynes	https://bitbucket.org/kovisoft/paredit
17:46	amalloy	jtoy: ^ is more or less the way clojure code is styled as well
17:46	jtoy	cool, am reading it n0w
17:47	technomancy	sorenmacbeth: weird; I don't recall anything cdt-related changing between 1.4.0 and 1.4.2, but I'll get that applied. thanks.
17:47	Raynes	Except the weird "You can put a line break before the first element of a list and after the last element" crap
17:48	sorenmacbeth	technomancy: I didn't test that by actually installing my patched version of lein-swank, only that including 1.4.2 in my project dependencies did make CDT work
17:48	technomancy	well it's better to be on the newer one anyway
17:48	clgv	I try to cache the byte[] definition of dynamically created classes by setting the ContextClassLoader of the current thread to a caching ClassLoader derived from DynamicClassLoader. but that does not seem to work
17:50	jtoy	Rationale: The parentheses grow lonely if their closing brackets are all kept separated and segregated.
17:50	jtoy	I'm sorry to hurt the parentheses feelings
17:50	jtoy	thats the stated reason for not placing closing brackets on their own lines
17:50	amalloy	yeah, his invented rationales are, to use his terminology, Questionable
17:51	jtoy	but its still the go to guide?
17:51	amalloy	well, the rule is still accurate
17:52	amalloy	and it's arguably the most fundamental rule of lisp coding style - if you put trailing parens on their own line, you get told politely once to fix it, and then mercilessly mocked if you refuse (this varies by community, of course)
17:52	aperiodic	heh, i remember doing that for about five minutes
17:52	technomancy	some communities mock mercifully
17:55	duck1123`	I tend to put my closing parens wherever when I'm working on the fn, but then when I'm done, I use paredit and backspace to clean it all up. (unless I forget)
17:55	amalloy	duck1123`: backspace?
17:56	amalloy	i find it much easier to just point at where the closing parens all belong, and hit ] until they get there
17:56	duck1123`	amalloy: nothing special. I just put my point on the last paren and hit backspace till I'm at the actual content
17:57	aperiodic	amalloy: what's ] do?
17:57	amalloy	mmm. try out the ] method - yours sounds like it's slower and more error-prone
17:57	amalloy	aperiodic: same as ), if you're in a form that's already closed - it just closes the current form, and puts the paren in the right place if it wasn't already
17:57	duck1123`	The ] method seems to only work for me when I don't want it to, so I resent it a little
17:57	amalloy	haha
17:58	amalloy	well, that's fair, i guess
17:58	autodidakto	technomancy: you need to a play-by-play peepcode :)
17:59	aperiodic	darn, paredit.vim doesn't move the parens to the right place
18:04	jtoy	so far I actually feel more comfortable without parens mode , i will test it more
18:05	amalloy	i mean, i haven't tried paredit.vim so this isn't 100% applicable, but you should expect to be less comfortable with paredit for a day or two
18:06	amalloy	but once you get used to it it's so much better than the alternative
18:06	jtoy	yeah, i can see how it can be really powerful, this is my first time with lisp/clojure
18:06	jtoy	everything is a little overwhelming, or maybe having so little is overwhelming
18:10	yoklov	i can see how going from having never used lisp to using lisp with paredit would be overwhelming. but really just think of it like autocomplete for your parentheses. there can be an awful lot of them sometimes.
18:11	TimMc	jtoy: Print out the paredit cheatsheet. There are ways of manipulating s-expressions that you didn't even know you wanted.
18:12	brehaut	i have a pinboard behind my laptop that is full of emacs keybindsings scribbled on paper and pinned up
18:12	jtoy	ok,I will, thanks
18:12	yoklov	brehaut: thats actually a really good idea
18:12	amalloy	<3 paredit-convolute-sexp
18:13	brehaut	yoklov: its the only way i can use emacs! :P
18:13	jtoy	silly question on earlier, why does this work: (first (filter #(some #{5} %) (partition-by identity (range)))) and this doesn't: (first (filter #(some 5 %) (partition-by identity (range))))
18:13	yoklov	i just settle for knowing about 20% of the keybindings in a given mode :p
18:13	jtoy	ClassCastException java.lang.Long cannot be cast to clojure.lang.IFn clojure.core/some (core.clj:2388) that makes no sense to me
18:14	yoklov	jtoy, because #{5} is a function and 5 is not.
18:14	technomancy	amalloy: what is convolute-sexp?
18:14	technomancy	that one just had me scratching my head
18:14	yoklov	,[(#{5} 5) (#{5} 6)]
18:14	jtoy	why can there be nested ## in there? i thought clojure doesn't allow nesting like that
18:14	clojurebot	[5 nil]
18:15	amalloy	technomancy: (fn [x] (let [y 10] \|point\| ...)) => (let [y 10] (fn [x] ...))
18:15	yoklov	jtoy: because #{} is a set literal
18:16	jtoy	yoklov: hmm, what does that mean?
18:16	yoklov	jtoy: #{foo bar baz} is a "set" containing foo bar and baz
18:16	technomancy	amalloy: huh... so mostly for binding forms?
18:16	amalloy	technomancy: for anything where you want to "swap" nesting levels
18:16	technomancy	I'll have to remember that one
18:17	amalloy	eg, (if foo (bar x) (bar y)) => (bar (if foo x) (bar y)) ;; you still need to manually delete the second bar
18:17	yoklov	jtoy: (set as in the abstract data type). it's special syntax, similar to the [1 2 3 4 5] syntax for vectors
18:17	amalloy	or rather, it turns into (bar (if foo x (bar y))); i typed it wrong
18:17	jtoy	ah, i see
18:19	yoklov	jtoy: right. Sets, like many of clojures builtin data structures, implement IFn, meaning you can use them as functions. If you give a set an argument, it will return that it if it is present in the set, and `nil` if the element is not.
18:20	jtoy	yoklov: I thought the # was turning it into a function
18:20	yoklov	nope
18:20	yoklov	thats only the case for #(
18:21	yoklov	jtoy: # is a special `dispatch` character for the clojure reader (e.g. parser). the character which comes afterwards determines what it does
18:21	yoklov	http://clojure.org/reader
18:26	yoklov	jtoy: so, to explain that error you got, filter takes a function (anything which implements IFn in this case, so sets are okay), and removes anything which returns false or nil. since you gave it #{5}, that means anything not contained in #{5} will be removed.
18:26	yoklov	When you gave it 5, it tried to use 5 as a function, but since its a number (a long), and does not implement IFn, you got an error.
18:50	konr	Wow! Clojure in GSoC!?!
18:51	Raynes	Yeah!
18:51	konr	haha, I'm gonna apply, then. Let's hope it's not too late to write a nice proposal
18:54	yoklov	haha, i applied :D
18:55	konr	what's your proposal, yoklov?
18:55	gtrak`	i kinda wish i were a student, i never worked on anythign this cool
18:55	yoklov	konr: improve clojurescript performance
18:56	konr	gtrak`: One of the reasons I'm considering a masters program is to keep doing GSoC
18:56	gtrak`	sweet, yea, do it
18:56	konr	yoklov: cool! I'll apply to the Emacs IDE. Gotta take a shower. Too excited!
18:57	gtrak`	with a job, I have freedom, but I'm tired xD

19:07	johnkpaul	Does anyone have any advice on how to setup lein-cljsbuild with jline wrapping the cljs repl?
19:10	replaca	Am I imagining it or are every-pred and some-fn defined really wrong when you call the function with multiple args? They do the combinitoric of one argument functions rather than calling each of the functions with the multiple args.
19:11	beeneto	does clojurebot run code? ._.
19:11	yoklov	beffbernard: try clojure.string/split
19:11	yoklov	,(clojure.string/split "12 23 4 5 5 6 7 6" #"\\s+")

19:11	clojurebot	["12" "23" "4" "5" "5" ...]
19:13	beffbernard	yoklov: ahh, thanks
19:14	yoklov	np :)
19:21	amalloy	replaca: yeah, that looks bizarre
19:22	dgrnbrg	Would it be possible to use robert-hooke or some other technique to provide a custom impl of code loading, to modify all clojure code on the fly while it's being loaded?
19:22	dgrnbrg	I'm thinking about how to do branch-level coverage
19:22	replaca	amalloy: I had old versions that worked the other way and I started to convert them, but it doesn't work. So now I have "new old versions" that short-circuit, but take multiple args
19:23	amalloy	dgrnbrg: it seems like it would be more pleasant to just shove your face in a meat grinder
19:23	dgrnbrg	if it were possible to essentially have every "if" actually be a macro/reader macro
19:23	dgrnbrg	I think that you could override require w/ alter-var-root hacks
19:23	dgrnbrg	and have that require eval the file after processing it
19:24	dgrnbrg	then branches could be instrumented
19:24	yoklov	why?
19:24	clojurebot	Why is the ram gone is <reply>I blame UTF-16. http://www.tumblr.com/tagged/but-why-is-the-ram-gone
19:24	dgrnbrg	you could even just read the file, then do a search & replace on the tree to change all the if to instrumentation.overrides/if
19:25	dgrnbrg	and the same for other functions that are conditional
19:25	dgrnbrg	In this case, then you could run the tests and measure test coverage and branches taken
19:25	dgrnbrg	including checking whether certain patterns happened, and checking that all combinations occured
19:25	dgrnbrg	as well as which lines were executed
19:25	technomancy	dgrnbrg: changing a macro doesn't retroactively change its callers
19:26	dgrnbrg	I would just want to insert an instrumentation function three
19:26	dgrnbrg	to log to a data structure which could be analyzed afterward
19:26	dgrnbrg	to match up the log data to metrics & statistics and line numbers
19:26	dgrnbrg	I just want to be able to dynamically instrument code paths
19:30	technomancy	since if is a special form I think you're stuck with bytecode-level manipulation
19:30	technomancy	it would be very nice if it were a var
19:32	dgrnbrg	technomancy: I have an idea to make it work. Give me 1 hr and I'll post on github a draft
19:33	technomancy	that'd be slick

19:36	sivajag	sorry
19:37	sivajag	next time i will put in pastebin
19:37	hiredman	sivajag: you are using clojure code aot compiled with a different version of clojure
19:39	sivajag	probably one of dependency is apt compiled
19:39	sivajag	i am not sure I am doing anything specifically for code to be compiled
19:39	sivajag	let me check
19:40	sivajag	thanks hiredman
20:04	dgrnbrg	technomancy: https://github.com/dgrnbrg/guzheng
20:05	dgrnbrg	You pass in a string and a transform function
20:05	dgrnbrg	and it evaluates it
20:05	dgrnbrg	it should be integrable into test code
20:05	dgrnbrg	I demonstrating tracing every invocation of println
20:13	technomancy	dgrnbrg: ah, I see. very tricky.
20:13	technomancy	I guess as long as you control the entry point this is feasible
20:15	technomancy	dgrnbrg: might be able to make it shorter by using read-string and binding ns
20:17	dgrnbrg	technomancy: but you can!
20:17	dgrnbrg	I'll write version 2 really quick
20:30	dgrnbrg	technomancy: any idea how to invoke a private fn in a module?
20:31	technomancy	dgrnbrg: sure, you can use the var: (#'my.ns/private-fn :hello)
20:37	llasram	muhoo: pushed to github and clojars: https://github.com/llasram/shady
20:43	muhoo	llasram: great, thanks!!
20:44	muhoo	technomancy: why the var quote?
20:44	technomancy	muhoo: that's how you invoke private defns
20:45	aperiodic	you want the var itself, since trying to resolve the symbol won't work, as it's private so that's not allowed
20:46	muhoo	ah! thanks.
20:47	muhoo	so private functions really aren't private
20:47	muhoo	not in the java sense of jailing stuff up
20:47	technomancy	private is a declaration of intent
20:48	arohner	muhoo: private isn't private even in java
20:48	arohner	it's just harder to access than in clojure
20:49	muhoo	i see, using reflection
20:49	arohner	right
20:51	technomancy	but everything is harder in java
20:52	aperiodic	mutating things is easier
20:54	yoklov	you can mutate objects easily in clojure
20:55	aperiodic	i'm not saying it's hard in clojure
21:10	heow	anyone know if you can make two namespaces share the same alias? For example, suppose I'd like to refer to both clojure.set and clojure.contrib.string as 's'
21:11	muhoo	you could create a new namespace "s", and then use clojure.set and string in it?
21:13	heow	muhoo, that's actually great idea!
21:18	brehaut	heow: why would you want to do that?
21:19	heow	I don't want to do it with those two, but I am requiring two namespaces that are similar in function and would like to refer to them both under the same alias. No function clashes.
21:19	amalloy	brehaut: when you really want to cry, you go around looking for onions to cut up. i assume this is a similar desire to cause confusion
21:20	brehaut	amalloy: lol
21:20	amalloy	"i know, i'll refer to two different namespaces by the same name"
21:21	amalloy	seriously heow, this is an idea i hate, but there are some people (eg ztellman) who love it. look up his potemkin library; it has all kinds of primitives for doing exactly this nonsense
21:35	technomancy	potemkin is a workaround for not having nstools
21:44	muhoo	nstools? this? http://code.google.com/p/clj-nstools/
21:51	muhoo	technomancy: by the way, i have to thank you for introducing me to clojure.
21:52	muhoo	i will pay it forward by helping out with lein, if needed, once i feel competent enough to
21:58	technomancy	muhoo: great =D
21:59	heow	technomancy++
22:09	autodidakto	cemerick: you don't have to turn it into a news show, but big updates, changes in best practices etc, is something you can mention on the podcast
22:09	autodidakto	also, you could pick a topic in (functional, lisp, whatever) programming and do a topical episode
22:11	cemerick	autodidakto: all true
22:11	cemerick	Sounds like a lot of work to make it a quality listen, though. I definitely am trying to keep the podcast casual.
22:11	cemerick	i.e. minimal work from me ;-)
22:12	cemerick	thus one interpretation of "lazy"
22:15	autodidakto	hrm, interviews about people and their project, what you've been doing so far, seems to be a straightforward balance..
22:16	autodidakto	And it doesn't have to be long. Short and sweet about a small but cool project works
22:16	autodidakto	The worse is to plan or worry so much about 30-1h of good content that you never finish it
22:20	muhoo	cemerick: sounds like you may have a guest host in the offing :-)
22:21	autodidakto	muhoo: volunteering? :)
22:26	autodidakto	you could probably get people to help you with the grunt work, though. Editting, emailing, maintaining the website, whatever
22:26	halarnold2000	got a problem: using either cake or lein, when I clean, compile, uberjar my noir app, and move it to another directory [one that doesn't have the supporting stuff in it] the application starts up, but does not find the page, the "we seem to have lost that one". Any clues as to what I may be doing wrong? no log files appear to be awry
22:27	halarnold2000	runs just fine using lein run
22:28	technomancy	halarnold2000: you must be loading stuff straight off the filesystem instead of using the resources dir
22:29	halarnold2000	technomancy: before when that happened, the message was something like "can't find such and such file", but the app appears to load normally, it just doesn't 'resolve' to the right page
22:30	technomancy	hm; I haven't used noir, but you may be interested in the wrap-resource ring middleware
22:30	halarnold2000	technomancy: thanks, I'll give that a try.
22:57	szx	i'm trying to figure out how to write a function (or find one) that collapses an ordered sequence according to a predicate that takes two consecutive items at a time
22:57	szx	in this case a series of events in time, and if they're close enough they should be grouped together
22:58	szx	and i just can't wrap my weak imperative mind around this
22:58	szx	anyone care to give me a hint?
22:59	brehaut	szx can you give an example input and output; im a little lost in your explaination
23:02	szx	sure, if you have something like this: ({ :time 1 :data 'a } { :time 2 :data 'b } { :time 5 :data 'c } { :time 8 :data 'd } { :time 10 :data 'e })
23:02	szx	and let's say the threshold is 2
23:03	szx	then i'd expect to get a list with 'a and 'b, then 'c alone, then 'd and 'e together
23:04	szx	similar to what partition-by would return
23:06	brehaut	szx incidentally, its not particularly idiomatic clojure code to quote symbols rather than just using a keyword
23:06	brehaut	likewise, using vectors over lists for preference
23:06	szx	heh, i was aware of that but thought it would make it confusing in this case
23:06	brehaut	it wouldnt
23:07	szx	in practice they're integers and the collection is actually a queue
23:07	brehaut	ok
23:08	szx	anyhow, this is as close as i've gotten: (partition-by #(< (- (:time (second %)) (:time (first %))) threshold) (partition 2 1 events))
23:08	szx	but that only works for pairs of events, not an arbitrary number
23:09	szx	and you're still left with duplicate events, but that's easy to take care of
23:09	amalloy	i feel sure that i've seen someone implement this already, and i think i've done it too
23:10	amalloy	like, it was on the mailing list...three weeks ago?
23:10	szx	i thought i'd find it in clojure.contrib
23:10	szx	i tried searching through the google group
23:11	amalloy	yeah, but google groups' search is terrible, not to mention you probably don't know what to search for
23:11	amalloy	i doubt i could find it now, and i read it the first time
23:11	szx	heh, true
23:12	muhoo	ok, i'm confused again. when lein/javac is building java files, what does it use as a classpath?
23:13	muhoo	because, i'm trying to import some aot clojure stuff, which does appear to exist, looking at the classes dir, but i'm getting the dreaded can't find symbol from javac
23:16	muhoo	hmm, maybe it's not compiling, if i run javac from the command line, no lein, still it's not finding the class, even though i think i'm seeing the right classfiles there
23:17	dgrnbrg	is there a way to take an ns and get a url/File to a candidate source file that clojure would load?
23:17	muhoo	i'm also seeing a file called .class, just that, no basename!
23:18	muhoo	something is skwewy
23:19	szx	amalloy, i think i found you: https://groups.google.com/d/topic/clojure/WVLHCM9KS3k/discussion
23:21	amalloy	that's actually not what i was thinking of; i didn't realize your problem was amenable to partition-between, but i guess it is
23:23	eggsby	why might I be losing all my routes in uberjar-ing a noir project? Is there a way to get more detailed logging?
23:23	szx	it should work, but i'll keep searching the list anyway
23:28	eggsby	:3
23:29	muhoo	that's just mystical. the damn Foo.class is right there. i can import it in clojure with no problems. but "javac -cp classes test/foo/FooTest.java" cannot see it
23:32	muhoo	ooh, that's freaky
23:33	muhoo	huh.
23:33	muhoo	so, javac is happy, if i make the class to the gen-class'ed class something OTHER than the path of the clojure source file
23:34	eggsby	ibdknox: does noir play nice wrt bundling for managed deployment? I'm have a weird problem where all routes are being dropped, I found a similar problem on stackoverflow, no responses and the guy's solution was to just use compojure :(
23:34	muhoo	i thought noir was compojure?
23:34	eggsby	:o
23:34	muhoo	or based on it anyway
23:35	muhoo	yep, in noir/projec.clj: [compojure "1.0.1"]
23:35	eggsby	http://stackoverflow.com/questions/9358238/404s-when-deploying-a-noir-war-to-jetty-on-squeeze
23:35	eggsby	ya, built on top of it
23:36	muhoo	weird
23:38	muhoo	i vaguely remember hearing of a bug in lein-ring that was some problem with servlet-api.jar hanging around
23:38	eggsby	http://refheap.com/paste/1734
23:38	muhoo	fixed in 0.6.3, is all i managed to write down though, sorry
23:38	eggsby	:) thanks
23:39	muhoo	took note of it because i'm about to do what you are doing, and i left that note in case i ran into anything like you've run into :-/
23:40	muhoo	eggsby: best if you can catch ibdknox when he's around
23:42	muhoo	eggsby: or this: https://github.com/weavejester/lein-ring/commits/master
23:43	eggsby	hmm muhoo
23:55	muhoo	hahaha! ok, by mangling the namespaces, i can get compile to work, but then lein jar pukes
23:55	muhoo	so lein compile, works. but lein jar, fails, NO_SOURCE_FILE.
23:56	eggsby	fun muhoo :(
23:56	eggsby	I tried including lein-ring 0.6.2 as an explicit project dep but no dice :(
23:56	muhoo	i suspect that compiling mixed java and clojure projects really was not a target use case
23:56	muhoo	eggsby: 0.6.3 has the fix, it says
23:56	eggsby	ah :3
23:58	eggsby	grr, any way to add that github repo as an explicit dep? its not resolving from the repos
23:59	eggsby	not up on clojars, I mean
23:59	muhoo	meaning it isn't in maven yet, eh
23:59	eggsby	mhmm
23:59	muhoo	there is a way to do it, i haven't messed with that yet
