00:04	technomancy	amalloy: CL's reader syntax for vectors implicitly quotes
00:04	technomancy	it's indescribably horrid.
00:15	amalloy	yes, that's how i remembered it, but i thought maybe my mind was just blocking out some even more painful memory
00:38	OwenOu	hi, i would like to know a way to improve this piece of code, (defn make-keyword [word]
00:38	OwenOu	(let [word (str/trim word)]
00:38	OwenOu	(->> (str/split word #"(\s+\|-\|_)")
00:38	OwenOu	(map str/lower-case)
00:38	OwenOu	(interpose \-)
00:38	OwenOu	str/join
00:38	OwenOu	keyword)))
00:38	Raynes	It looks a lot better on refheap.com. :p
00:38	OwenOu	don't like the "let" to trim the word, but not sure how to pass word into "str/split"
00:38	Raynes	What is this code meant to do?
00:39	Raynes	(And seriously, if you don't mind, paste it on refheap.com)
00:39	OwenOu	Raynes: make a random string into keyword
00:39	Raynes	Is there a particular reason you can't just use 'keyword'?
00:39	OwenOu	https://www.refheap.com/paste/2893
00:40	OwenOu	Raynes: the string can be separated by space
00:40	Raynes	One thing: ##(keyword "foo_bar") ; you can have underscores in keywords.
00:40	lazybot	⇒ :foo_bar
00:41	OwenOu	but how about "foo bar"?
00:41	amalloy	you usually shouldn't be making random strings into keywords anyway
00:42	amalloy	but it's perfectly possible to just leave in the space: ##(keyword "pretty much any string can be a keyword")
00:42	lazybot	⇒ :pretty much any string can be a keyword
00:43	OwenOu	amalloy: i would like to convert the space to "-" and append the string
00:44	Raynes	Well, the point is that you probably don't need to.
00:44	OwenOu	my problem is if i make str/trim as the first function in ->>, i can't pass its result to str/split
00:44	Raynes	Keywords can have spaces in them. More importantly, why do you need keyword for this particular problem?
00:44	Raynes	keywords*
00:45	OwenOu	Raynes: maybe not necessary a keyword, i just need to make it as the key for a map, it can be string
00:45	OwenOu	but the requirement is to replace all spaces with "-"
00:45	OwenOu	say "foo bar" -> "foo-bar"
00:46	Raynes	&(.replace "foo bar" " " "-")
00:46	lazybot	⇒ "foo-bar"
00:46	OwenOu	Raynes: but str/trim has to come first, otherwise " foo bar" -> "—foo-bar"
00:47	Raynes	Note that the existence of ->> does not necessarily mean it is a requirement.
00:47	Raynes	If your code doesn't work right with it, it probably isn't the pattern it is designed for.
00:47	OwenOu	does ->> only work for function that takes the previous result as the last argument?
00:48	OwenOu	like str/split, the argument i get for the previous result, e.g., str/trim, is not the last one, e.g., (str/split word #"\s+")
00:49	OwenOu	word is in the middle
00:50	Raynes	&(-> " foo bar baz_quux" clojure.string/trim (clojure.string/replace #"(\s+\|-\|_)" "-"))
00:51	lazybot	⇒ "foo-bar-baz-quux"
00:51	Raynes	OwenOu: ^
00:52	Raynes	&(-> " foo BAR baz_quux" .toLowerCase clojure.string/trim (clojure.string/replace #"(\s+\|-\|_)" "-"))
00:52	lazybot	⇒ "foo-bar-baz-quux"
00:52	Raynes	That should do the same thing you wanted, right?
00:52	Raynes	I would just use the string rather than convert to a keyword though.
00:52	OwenOu	What's the difference between -> and ->>
00:53	Raynes	(-> foo (bar baz)) = (bar foo baz); (->> foo (bar baz)) = (bar baz foo)
00:53	Raynes	The difference is that -> threads each form in as the second argument, while ->> threads it as the last.
00:54	OwenOu	Raynes: what if i need both?
00:54	OwenOu	i guess i have to (-> ( ->> xxx) xxx)
00:55	Raynes	Or just don't use either of them.
00:55	metellus	then neither will help on its own
00:55	OwenOu	i guess i would need comp and partial in this case?
00:55	Raynes	You don't have to use these things just because they exist. If they make one particular piece of code easier and cleaner to express, then use them. Otherwise don't.
00:55	Raynes	For what case?
00:56	Raynes	The code I just gave you should suffice, right?
01:02	OwenOu	Raynes: that's sufficient, still trying to understand the difference between -> and ->>
01:02	OwenOu	thanks
01:02	coventry	What does it generally mean when the repl just says "; Evaluation aborted" without providing a backtrace?
01:03	Raynes	coventry: Means you should type (pst *e)
01:03	Raynes	:p
01:04	coventry	Thanks. Why does that happen? (I'm doing this in swank, in case it matters.)
01:04	Raynes	Usually swank opens up a buffer with the stacktrace.
01:04	Raynes	Not sure I've ever seen it not do that.
01:05	OwenOu	Raynes: can u help me to understand why it uses ->> here? https://www.refheap.com/paste/2894
01:05	OwenOu	this is an example from the clojure programming book
01:06	amalloy	i used to always get stacktraces, and then eventually i did something (what?) and now like a quarter of the time, just ; Evaluation aborted
01:06	coventry	Raynes: I'm sure it's wrongheaded clojure code, but I have some which is reliably having that effect: http://pastebin.com/tiLTmJW9
01:07	coventry	It's happening to me less frequently than that. Maybe a tenth of the time.
01:07	amalloy	coventry: whaaaaat is that code
01:08	coventry	That is my ongoing attempt to solve 4clojure problem #69.
01:08	amalloy	hey, that was my guess!
01:09	amalloy	or at any rate it looks like an attempt to write merge-with
01:09	coventry	yep
01:10	amalloy	well, the first issue seems to be that you're using contains? wrong
01:10	amalloy	~contains
01:10	clojurebot	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
01:10	amalloy	like, you're mapping over the values of mm, and then treating those as if they were keys in s/mm
01:11	coventry	Ohhh, I'm such a dope. Thanks for the pointer.
02:47	Malondron	Hi, I have a clolurescript question: I am not really familiar with javascript, but am using it for some simple things. Now I want to change to clojurescript. NowI have a problemthough: how do I access specific elements in an element containing a list(vector) of items ,e.g. the different option items in an select element? (.. form -select-name -options) gives me the list of options, but I cannot find out a way to get the [0] element. I
02:47	Malondron	think I have tried every likely way now without luck.
02:49	ivan	maybe `into` the Array into a vector first?
02:50	ivan	some CLJS users here might know better
03:00	borkdude	Malondron what is the type of your collection?
03:01	borkdude	Malondron don't know much about clojurescript, but if the collection is seqable, you can just call first on it: &&(first [1 2 3])
03:02	amalloy	good try, borkdude: ##(first [1 2 3])
03:02	lazybot	⇒ 1
03:03	borkdude	amalloy I keep forgetting this notation ;)
03:05	kmicu	# # , & where is this notation specified? :)
03:05	kmicu	Malondron: Why not simply ,(nth '(1 2 3) 2)
03:16	pepijndevos	What constitutes a "conditional put" in datomic? Is that just compare-and-set! behavior?
03:17	kmicu	pepijndevos: try in #datomic channel if you don't get answer here
03:17	Malondron	Hi, I guess the problem is that I don't know what type of collenction I acttually get from the above code. The translated code is: form.select-name.options, which is fine. I just cannot get a .[0] to show up in the translation in any way. first does not work, -[0] does not work, 0 does not work :0 does not work, (options 0) does not work, etc.
03:18	kmicu	Malondron: but this is in js not cljs?
03:20	Malondron	Well, I am translating into javascript.
03:20	borkdude	Malondron you can call type on it
03:20	borkdude	,(type [1 2 3])
03:20	kmicu	Malondron: but where you can't acces in js or cljs? :)
03:20	clojurebot	clojure.lang.PersistentVector
03:22	kmicu	// collection access is first class (def m {:foo 1 :bar 2}) (get m :foo) (def v ["red" "blue" "green"]) (nth v 0)
03:22	kmicu	// map access is a static// language feature var m = { "foo": 1, "bar": 2}; m["foo"];m.foo; // array access is a static// language feature var a = ["red", "blue", "green"];a[0];
04:01	alex_baranosky	does anyone have sagely wisdom on why some functions have :ns and :name metadata on them, but others don't?
04:01	amalloy	alex_baranosky: not many functions do. if you think they do, you're probably looking at the metadata on the var, not the function
04:03	alex_baranosky	,(meta integer?)
04:03	clojurebot	nil
04:05	alex_baranosky	&(meta integer?)
04:05	lazybot	⇒ nil
04:06	alex_baranosky	ahhhhh it is a 1.2 to 1.3 thing,
04:06	alex_baranosky	we're still using 1.2 here
04:06	alex_baranosky	if you wanted a the name a of a given function how would you go about getting it?
04:07	amalloy	you can't
04:07	alex_baranosky	dang
04:07	amalloy	functions don't have names
04:07	alex_baranosky	they do in 1.2
04:07	alex_baranosky	:)
04:07	alex_baranosky	at least a lot of them do
04:07	amalloy	meh. def was broken
04:08	amalloy	did some weird shit with copying metadata from vars to functions, sometimes, for no real reason
04:08	amalloy	or that was defn, i guess? i dunno
04:08	alex_baranosky	is there a way to achieve a similar result without needing to us a macro to snag the symbol , and other crap I don't want to stoop to?
04:08	alex_baranosky	basically I want to accept any predicate for my function, and then printout "Your predicate 'foo?' filed…"
04:09	amalloy	&(let [named-first (with-meta first '{:name first})] (name (meta named-first))) ;; not very satisfying, huh?
04:09	lazybot	java.lang.ClassCastException: clojure.lang.PersistentArrayMap cannot be cast to clojure.lang.Named
04:09	alex_baranosky	failed*
04:09	amalloy	&(let [named-first (with-meta first '{:name first})] (:name (meta named-first)))
04:09	lazybot	⇒ first
04:09	amalloy	your function has to be a macro
04:10	amalloy	and even then it won't work very well because what if they pass an anonymous function?
04:10	alex_baranosky	anonymous functions are all bets off, but… I figured I'd live with that
04:10	alex_baranosky	worth the tradeoff in simplicity
04:10	amalloy	it doesn't sound simpler. easier, maybe
04:11	alex_baranosky	I could change my code to accept a predicate and a predicate-name, and then wrap a thin macro layer around it to get the name of the predicate symbol and pass it in
04:11	Malondron	Well, let's say I want to set the first option in a select element in a form. I want to write: (set! (first (.. form -select-name -options)) (js/Option. "New" "New")), but this fails as first does not work with the compiler (nor does nth, or any other reasonable "usual" clojure way to use collections). And the problem is not with set!; trying to access the value property fails as well, so I am not getting the first (or nth 0)
04:11	Malondron	element. At least not in the form I want.
04:11	alex_baranosky	it is easier and simpler
04:12	alex_baranosky	adding a layer of macros just to get a predicate's name seems silly
04:12	borkdude	can protocols be used to "alter" the toString of, let's say a ClasscastException?
04:12	alex_baranosky	(which is what I was suggesting it was simpler than)
04:12	alex_baranosky	I think the answer to that is no
04:13	alex_baranosky	thanks smalloy for the info
04:13	alex_baranosky	now I don't want to move to 1.4 ;)
04:15	borkdude	for example, what's going wrong here? https://www.refheap.com/paste/2897
04:55	Malondron	Actually, I just found out that aget/aset does what I want in this case.
05:41	Dvyjones	Any idea why this outputs question marks instead of the ticks it's supposed to output? https://gist.github.com/2818174
05:47	kral	namaste
05:47	rodnaph	Dvyjones: where are you viewing the output? font probably doesn't support those characters.
05:53	mittchel	Why am I getting a nil when I do the following: (my-map :a) in this function: (defn my-map {:a "appel" :b "peer"})
05:53	mittchel	maps are supposed to behave as functions, right?
05:56	andyfingerhut	({:a "appel" :b "peer"} :a) will do what you are expecting. So will ((my-map) :a) -- note the extra parens so that my-map is called with no args, and the return value of a map is then used as a function.
05:57	andyfingerhut	You'll have to change it to (defn my-map [] ...) to specify the function takes no arguments, though.
05:57	mittchel	Hm thanks.. probably an mistake in the course :P
05:57	Dvyjones	rodnaph: In my console, and the font does support those characters.
05:58	mittchel	andyfingerhut: when I try that Im getting: java.lang.IllegalArgumentException: Wrong number of args (0) passed to: user$my-map (NO_SOURCE_FILE:0)
05:58	rodnaph	Dvyjones: are you going through the REPL?
05:59	andyfingerhut	when you try what?
06:00	mittchel	9
06:00	mittchel	((my-map) :a)
06:01	andyfingerhut	After changing the defn to (defn my-map [] {:a ...}) ?
06:01	Dvyjones	rodnaph: Nope.
06:01	mittchel	(get my-map :a) returns nil too lol
06:01	Dvyjones	rodnaph: Well, I tried importing that into the REPL, and that failed too.
06:01	andyfingerhut	Are you sure you don't want (def my-map {:a "appel", ...}) (note def not defn)
06:02	andyfingerhut	that will define a var called my-map that you can use the way you are describing, rather than a function.
06:02	mittchel	Ye
06:03	mittchel	thankyou :D
06:03	andyfingerhut	(def my-map {:a "appel" :b "peer"}) (my-map :a) => "appel"
06:03	andyfingerhut	np
06:03	rodnaph	Dvyjones: not sure then sorry mit. Try (println "CHAR") in various places (shell, repl) to see where the problem is.
06:27	mittchel	() are literals for lists right? Since (= '(3 4 5) (map (partial + 2) [1 2 3])) results in (3 4 5)
06:28	borkdude	mittchel '(1 2 3) equals to (list 1 2 3)
06:30	mittchel	Yep I know cause ' makes sure that it doesn't see the 1 as a function with arguments 2 and 3.. but when I do the following in the repl: (map (partial +2) [1 2 3])) this gives me (3 4 5).. is this a map as a result or a list? Cause I thought () was the literal for a list:P
06:30	borkdude	mittchel it is a sequence
06:30	Raynes	It is a seq.
06:30	borkdude	,(type (map (partial + 2) [1 2 3]))
06:30	clojurebot	clojure.lang.LazySeq
06:31	borkdude	mittchel a sequence is printed as (. . .)
06:31	mittchel	Alright, thanks..
06:31	mittchel	so basically a list can be seen as a sequence too?
06:31	borkdude	mittchel yes
06:32	borkdude	,(seq? (list 1 2 3))
06:32	clojurebot	true
06:32	lucian	afaik, they just both print the same
06:32	mittchel	Pff I'm always messing that up :P
06:32	lucian	,(seq? [1 2 3])
06:32	clojurebot	false
06:32	lucian	,(seq? (seq [1 2 3]))
06:32	clojurebot	true
06:32	lucian	ok, so i'm wrong
06:34	mittchel	,(seq [1 2 3])
06:34	clojurebot	(1 2 3)
06:34	mittchel	,([1 2 3])
06:34	clojurebot	#<ArityException clojure.lang.ArityException: Wrong number of args (0) passed to: PersistentVector>
06:34	borkdude	,[1 2 3]
06:34	clojurebot	[1 2 3]
06:34	mittchel	,[1 2 3]
06:34	clojurebot	[1 2 3]
06:34	mittchel	ye hehe
06:34	mittchel	se you are actually right lucian.
06:36	mittchel	,(clojure.set/intersection #{1 2 3 4} #{3 4 5 6})
06:36	clojurebot	#<ExecutionException java.util.concurrent.ExecutionException: java.lang.RuntimeException: java.lang.ClassNotFoundException: clojure.set>
06:37	borkdude	&(clojure.set/intersection #{1 2 3 4} #{3 4 5 6})
06:37	lazybot	⇒ #{3 4}
06:37	borkdude	mittchel apparently, clojurebot has not required clojure.set
06:37	mittchel	too bad
06:37	borkdude	mittchel but you can also use lazybot with &
06:38	mittchel	What's the difference between those two?
06:38	borkdude	mittchel also you can evaluate an expression like this: ##(+ 1 2 3)
06:38	lazybot	⇒ 6
06:38	borkdude	mittchel they are two different bots
06:38	mittchel	ahh
06:38	borkdude	mittchel http://www.unexpected-vortices.com/clojure/brief-beginners-guide/getting-help.html
06:39	mittchel	thats much easier
06:40	borkdude	mittchel lazybot was implemented by Raynes I believe
06:41	mittchel	It comes in very handy
06:49	leo2007	I started swank-clojure in a terminal and connect to it from emacs.
06:50	leo2007	but I must provide emacs with the real IP address (i.e. not localhost or 127.0.0.1) otherwise it won't connect.
06:50	leo2007	ideas?
06:50	leo2007	I can connect to my CL swank server using localhost
07:52	kilon	anyone here used Quil with Clojure, wondering how mature really is
08:03	soulman	hello
08:06	mrphoebs	hi @soulman
08:06	soulman	i'm searching for a possibility to splice a list as flat function arguments
08:06	mrphoebs	use apply
08:07	soulman	e.g. a list of elements as sub elements of an xml element
08:07	soulman	(element {} (<splice> (map element-list coll))
08:08	soulman	)
08:08	mrphoebs	hmmm
08:11	mrphoebs	@soulman you want to flatten the list
08:11	mrphoebs	?
08:12	soulman	but it's still a list after flattening
08:20	the-kenny	soulman: You want something like (magic + (list 1 2 3))?
08:21	soulman	yep
08:21	PKHG	raek: hello, you helped me yesterday, isn't it? got lein working too in Emacs (all on Vista) ;-)
08:21	the-kenny	magic is called apply ;)
08:21	the-kenny	,(apply + (list 1 2 3))
08:21	clojurebot	6
08:24	pepijndevos	What happens to a protocol when you AOT it?
08:26	PKHG	Hallo, busy with clojure since yesterday a newbie :-) How do I do this: a bunch of *java files form webcompmath at sourceforge and is it possible to use those in clojure , a link explaining this maybe?
08:27	soulman	i need something like (magic xfn stuff [1 2 3]) where xfn is defined like (defn xfn stuff & content) but content is treated as a single argument when you give it a coll
08:27	G0SUB	soulman, apply
08:27	mrphobes	Hi PKHG
08:27	G0SUB	,(apply + 1 [2 3 4])
08:27	clojurebot	10
08:27	soulman	like data.xml element
08:28	mrphobes	Clojure can import any complied java files as long as they are on the classpath
08:28	soulman	=> (doc element)
08:28	soulman	-------------------------
08:28	soulman	clojure.data.xml/element
08:28	soulman	([tag & [attrs & content]])
08:29	G0SUB	soulman, couldn't understand your problem.
08:35	PKHG	mrphobes: hmm you mean I have to compile my *.java into a jar and then ... how to define a classpath in clojure?
08:37	mrphobes	PKHG: this talks about how classpath with repl http://lpsherrill.blogspot.in/2009/05/clojure-classpath-made-easy.html
08:37	PKHG	thanks looking at your linkg ;-)
08:37	mrphobes	If you are working on a project using 'lein' the simplest way would be to put your jars in the lib directory, but this is not the right way
08:38	mrphobes	The right way is to include the jar as a dependency in lein
08:38	mrphobes	np
08:40	mrphobes	@PKHG also look at this http://stackoverflow.com/questions/2121670/how-do-i-include-java-stuff-in-jar-files
08:40	PKHG	next to read ;-)
08:44	PKHG	hmm yes I think now what to do with CLASSPATH ... THANKS!
08:44	soulman	G0SUB: to state it as plain as possible, I want to create an xml element with a list of elements as content.
08:45	G0SUB	soulman, doesn't "apply" work in your case?
08:45	soulman	the list of elements is created dynamically and the elements contain sub elements so flatten doesn't do the job. it flattens to much
08:46	soulman	apply doesn't seam to do the job because of the tag name and the attributes of the element fn
08:47	G0SUB	soulman, some example code would help.
08:57	soulman	G0SUB:
08:57	soulman	(defn xml-element [el]
08:57	soulman	(element :b {}
08:57	soulman	(element :c {:name (:name el)})))
08:57	soulman	(defn xml-elements [coll]
08:57	soulman	(element :a {}
08:57	soulman	(map xml-element coll)))
08:57	soulman	(indent-str (xml-elements [{:name "Hello"} {:name "World"}]))
08:57	soulman	#<IllegalArgumentException java.lang.IllegalArgumentException: No implementation of method: :emit-element of protocol: #'clojure.data.xml/Emit found for class: clojure.lang.LazySeq>
09:00	G0SUB	soulman, looking
09:00	soulman	(defn xml-elements [coll]
09:00	soulman	(apply element :a {}
09:00	soulman	(map xml-element coll)))
09:01	G0SUB	soulman, can you paste all the code somewhere?
09:01	G0SUB	soulman, refheap.com
09:01	soulman	seems to work in this case ;-)
09:02	soulman	"<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<a>\n <b>\n <c name=\"Hello\"/>\n </b>\n <b>\n <c name=\"World\"/>\n </b>\n</a>\n"
09:02	soulman	that's what I like to see. ;-)
09:03	G0SUB	soulman, paste the code and your comments on refheap.com and I will take a look.
09:03	soulman	G0SUB: thanks for making me build a simple sample code. The problem seems to be lurking in some of my own code.
09:04	G0SUB	soulman, that's what I thought.
09:04	soulman	rubber ducking ;-)
09:04	G0SUB	soulman, it's always better to find a minimum test case to track down problems.
09:07	dan_b	cripes, how much easier is it to install clojure these days than it used to be?
09:08	soulman	G0SUB: sure, and select isn't broken ;-)
09:16	tominated	Hello
09:16	tominated	can anyone here help me with an issue I'm having with compojure?
09:18	rodnaph	depends on what the issue is!
09:18	tominated	haha i'm getting an exception when browsing to a route
09:18	tominated	I have it on github at https://github.com/tominated/twitface
09:19	rodnaph	what's the exception?
09:19	tominated	clojure.lang.ArityException: Wrong number of args (3) passed to: PersistentArrayMap
09:19	rodnaph	sounds like you've missed the args [] from ur handler?
09:19	rodnaph	which route exactly?
09:20	tominated	it happens whenever I use the routes included from the controller files, which are '/users/', '/posts/' and 'comments'
09:21	rodnaph	tominated: try taking the parenthesis off your index function. ie. (GET "/posts/" [] index)
09:22	tominated	will do
09:22	rodnaph	they you might have to add the ring request object as a parameter to your handler, (defn index [req] ...)
09:23	tominated	yeah that seems like the case
09:23	tominated	it just had an exception saying there was too many arguments
09:25	tominated	hmmmm odd
09:25	tominated	that goes back to the same exception
09:25	tominated	2012-05-28 23:20:37.605:WARN:oejs.AbstractHttpConnection:/posts/
09:25	tominated	clojure.lang.ArityException: Wrong number of args (3) passed to: PersistentArrayMap
09:30	rodnaph	tominated: it's probably the way your adding the routes in core.clj then, i've not seen that syntax before and can't imagine how it works.
09:31	tominated	I was roughly following the tutorial at https://devcenter.heroku.com/articles/clojure-web-application
09:31	tominated	it may be because they use an old version of compojure
09:31	tominated	there were a few things I had to change because of outdated packages
09:35	kilon	anyone can show me instructions on how to install leiningen in windows ?
09:35	tominated	rodnaph: I may just chuck all the routes in the core file
09:36	rodnaph	or import them by calling the controller functions eg. (my.controlls/routes)
09:38	tominated	how do you mean?
09:39	coventry	How do I turn a list of chars into a string?
09:40	coventry	Never mind, I forgot to google first.
09:41	tominated	ok, it seems that the error changes when I add or remove the argument from the controller's index functions
09:42	tominated	when I have it as (defn index [] ….) it says the following
09:42	tominated	clojure.lang.ArityException: Wrong number of args (1) passed to: posts$index
09:43	tominated	and when i have it as (defn index [request] …) is shows up this
09:43	tominated	2012-05-28 23:36:45.085:WARN:oejs.AbstractHttpConnection:/posts/
09:43	tominated	clojure.lang.ArityException: Wrong number of args (3) passed to: PersistentArrayMap
09:43	tominated	wait a second
09:45	tominated	it seems like it may be my template that's screwing up
09:53	tominated	Oh you have got to be kidding me
09:54	tominated	it was because I was using a now non-existent function
09:56	tominated	rodnaph: thanks for all your help!
10:01	pandeiro	is there something i can install to paste to refheap directly from emacs?
10:02	tmciver	pandeiro: yes, there is a refheap package.
10:03	pandeiro	tmciver: available from marmalade? is it called refheap?
10:03	tmciver	pandeiro: yes, just do a search for 'refheap' after doing M-x package-list-packages
10:05	pandeiro	hmmm, marmalade-repo.org is down i think
10:05	pandeiro	ouch and package-list-packages is blocking
10:06	tmciver	ah, yes, it is for me too.
10:08	michaelr`	is there a way to break execution at the repl?
10:09	pandeiro	tmciver: finally went through but i don't see any refheap package
10:09	pandeiro	maybe that's stale, site still seems to be down
10:13	pandeiro	ok i typed it in by hand: https://www.refheap.com/paste/2898
10:15	pandeiro	michaelr`: i think C-c C-c does it no?
10:16	tmciver	pandeiro: yes, I do see the refheap package now. I have version 0.0.1.
10:16	twhume	Hi, I'm trying to flatten a sequence of sequences of sequences… but not completely. What I have is the sequence (((:istore 0 :istore 0) (:istore 0 :istore 1) (:istore 1 :istore 0) (:istore 1 :istore 1)) ((:ixor :ireturn))) and what I'd like is ((:istore 0 :istore 0) (:istore 0 :istore 1) (:istore 1 :istore 0) (:istore 1 :istore 1) (:ixor :ireturn)) … any ideas? (clojure n00b)
10:18	Bronsa	,(mapcat identity '(((a b) (c d)) ((e f))))
10:18	clojurebot	((a b) (c d) (e f))
10:19	twhume	Bronsa: aha, thank you. Is there any magic in that, or will a read through docs make it clear? ;)
10:19	Bronsa	no magic
10:21	Bronsa	,(reduce concat '(((a b) (c d)) ((e f))))
10:21	clojurebot	((a b) (c d) (e f))
10:21	pandeiro	tmciver: yeah my package list is out of date and marmalade is not responding... oh well... wanna help me with my macro? ;)
10:24	tmciver	pandeiro: I would but my macro experience is almost non-existent. :/
10:25	_Azrael_	Cbg
10:26	_Azrael_	Fuckkkkkkkk
10:27	pandeiro	wow the slime repl remembers history from previous sessions...
10:42	scottj	does :jvm-opts ["-Xmx256M"] cap just the map, or also the lein process jvm? is there is there a separate option for that?
10:42	scottj	s/map/app/
10:44	p_l	scottj: I believe the app, because lein can't exactly change those options after launching (unless it relaunched itself, and lein is slow enough without doing that)
10:47	rvgate	How do i remove an entry within an atom using clojure?
10:48	KIMAvcrp	what is stored in your atom ?
10:49	rvgate	KIMAvcrp, currently the atom has: {"agrg" {:title "agrg", :authors "wrrk", :publisher "wadst"}, "bla" {:title "bla", :authors "Henk", :publisher "piet"}}
10:50	rvgate	and im trying to create a simple function (defn delete-book [title]
10:50	lucian	rvgate: you're probably looking for dissoc, to replace the atom's value with another
10:51	lucian	rvgate: something like (swap! book dissoc title)
10:53	rvgate	thank you lord \o/
10:53	rvgate	thats you lucian :P
10:53	lucian	i'm glad it helped :)
10:54	rvgate	just learning clojure, no offence, but the documentation is horrible :/
10:55	pandeiro	rvgate: http://clojure.org/api ?
10:55	rvgate	pandeiro, there is documentation, yes... but some descriptions and examples are weird
10:56	pandeiro	rvgate: do you use the repl?
10:56	rvgate	ofcourse
10:56	rodnaph	i concur! the clojure docs assume a lot of knowledge. here's a great example of assuming a lot of stuff: http://clojure.org/macros
10:57	pandeiro	you know (dir ...) (doc ...) etc?
10:58	rvgate	another example: http://clojure.org/atoms, am i the only one that finds it weird that the example on that page seems inrelevant... i dont see why elapsed time has anything to do with atoms...
10:59	mfex	the documentation on clojure.org is a reference, not a tutorial. for that a book is better
10:59	gfredericks	rvgate: the elasped time bit there is demonstrating that the naive fib algorithm is speeded up by memoization
10:59	rvgate	gfredericks, and how is that relevant to atoms?
10:59	gfredericks	it's a bit indirect, but it relates because memoize is implemented with an atom
11:02	pandeiro	rvgate: clojuredocs.org and clojure.org/cheatsheet <- the latter shows you the principal functions for dealing with atoms
11:04	gfredericks	somebody could start a clojure-newb-docs project which, when included, replaces all the docstrings in clojure.core :)
11:08	rvgate	i think the docs should show simple examples, using clear variable names (not using x y z, m, ret, etc etc) so everything becomes more understandable :P but thats just me
11:14	justint	anyone know if there's a marmalade-repo mirror anywhere? it seems to be down
11:21	rvgate	lucian, sorry to bother you again, assoc inserts, dissoc deletes... but how do i update?
11:21	lucian	rvgate: assoc with the key you want
11:21	rvgate	seriously....
11:22	lucian	rvgate: assoc just returns a new map with that value at that key
11:22	gfredericks	,(assoc {:a 1 :b 3} :b 20)
11:22	clojurebot	{:a 1, :b 20}
11:27	soulman	hi
11:28	lucian	rvgate: what other language are you more comfortable with?
11:30	soulman	if i compile some code with clojure, referenced jar files get unzipped to clojure.compile.path. Is that correct?
11:31	soulman	so they land in the resulting jar file which i build from clojure.compile.path?
11:34	edw	Running in the SLIME REPL, (clojure.java.io/resource ".") returns a URL to my project's test directory. This puzzles me. Shouldn't it return a URL to the project root?
11:39	wmealing_	in the interest of anti wheel re-invention is there a jar which watches a directory and can load the files (kind of like a plugin loader ?)
11:39	edw	There's watchtower on github.
11:39	edw	It's crude but effective.
11:39	mfex	soulman: no; referenced jars are not unzipped, perhaps you are looking for "lein uberjar" which packages a project and all its jar dependencies into one jar
11:40	wmealing_	edw, ok
11:40	edw	It doesn't using any kqueue-like fancyness: it polls.
11:41	wmealing_	thats probably good enough for now
11:42	edw	Something more sophisticated might require JNI: I don't think the JVM exposes any abstraction for kqueue or similar system facilities.
12:06	bordatoue	anyone facing problem installing leningen 2 installation on RHEL
12:06	rvgate	lucian, java and php mostly... (sorry, was having dinner)
12:06	wmealing_	more specifically ?
12:06	PKHG	hello, who can help a newbie? trying to use Java from clojure: here is my problem visible: http://www.petergragert.info/pmwiki/pmwiki.php/Clojure/Applet
12:07	wmealing_	bordatoue, that was for you.
12:07	PKHG	Peter thats me ;-)
12:07	bordatoue	i followed the instruction specified in https://github.com/technomancy/leiningen
12:07	PKHG	bordatoue: what is RHEL?
12:08	lucian	rvgate: right, so in java you'd have Map.set(key, val). you can both add and "overwrite" keys with that. just like clojure's assoc
12:08	bordatoue	downloaded the script , changed the mode . but when I try to execute lein self-update , i get Exception in thread "main" java.lang.NoClassDefFoundError: java/util/concurrent/Callable
12:08	bordatoue	at clojure.main.<clinit>(main.java:19)
12:08	wmealing_	el6 ?
12:08	soulman	mfex: no, I'm not building with lein but with 'java clojure.lang.Compile...'
12:08	bordatoue	RHEL -- red hat scrap
12:09	wmealing_	are you on version 6 ?
12:09	bordatoue	yes
12:09	PKHG	hmm sorry, installed yesterday on Vista with lein.bat ..
12:10	wmealing_	bordatoue, disclaimer, i work for red hat.
12:10	bordatoue	Kernel version is 2.6.18-194.el5
12:10	wmealing_	i dont think the kernel verrsion has much to do with it.
12:10	wmealing_	i assume the file downloaded ?
12:10	wmealing_	ie, you saw a progress meter ?
12:11	bordatoue	nothing happens it throws an exception stated above
12:12	wmealing_	ok, el6 current here, and not getting any issues
12:12	wmealing_	default install.
12:12	bordatoue	did you just downloaded the script and executed it
12:12	wmealing_	yes
12:12	wmealing_	i'll paste you
12:12	bordatoue	i did not use any package manager
12:13	wmealing_	http://hastebin.com/fajudocaku.vhdl
12:13	wmealing_	neither did i
12:13	wmealing_	do you have wget or curl installed
12:14	bordatoue	i do have wget installed
12:14	PKHG	hallo again, someone used a java applet from closure?
12:15	bordatoue	i will try deleting all the files
12:16	bordatoue	you don't seem to use --no-check-certificate option for wget , could that be th reason
12:17	wmealing_	i'm pretty sure it is
12:17	wmealing_	line 128
12:17	coventry	Is there such a thing as an anonymous macro? I'm working on a 4clojure problem where I think a macro would be useful, but the 4clojure evaluator doesn't allow defs.
12:18	gfredericks	coventry: nothing available from 4clojure I don't think
12:18	wmealing_	but by all means, give it a go.
12:18	gfredericks	the clojure.tools.macro package has tools for that
12:18	coventry	gfredericks: Thanks.
12:19	wmealing_	bordatoue, bash -x lein self-update
12:20	wmealing_	maybe you're mising something, and that should show the code-path its executing
12:20	bordatoue	okay
12:20	wmealing_	however, i dont think this is a rhel "problem", you're missing something that is required/assumed to be installed
12:20	bordatoue	http://hastebin.com/cayutiweti.diff
12:22	wmealing_	what java are you running
12:22	bordatoue	current path is set to 1.4
12:23	wmealing_	i dont know what that means
12:23	wmealing_	i'm not running third party java
12:23	wmealing_	and i dont think that clojure works with the older jdks
12:23	bordatoue	java 4
12:23	wmealing_	(again, i dont write java)
12:23	bordatoue	i can try changing it to jdk 6 or 7
12:24	wmealing_	java-1.6.0-openjdk-1.6.0.0-1.41.1.10.4.el6.x86_64
12:24	wmealing_	i'm using whatever ships with el6.
12:25	bordatoue	wmealing_: thanks, it seems to work with jdk 6
12:26	wmealing_	yeah, i imagine that the util.concurrent stuff isnt in 1.4
12:26	wmealing_	just taking a punt
12:26	wmealing_	thanks for calling redhat support :P
12:27	bordatoue	shouldn't the script doing some checks before proceding
12:27	wmealing_	if you think so, lodge a bug
12:27	wmealing_	or a patch
12:31	KIMAvcrp	hey #clojure
12:31	wmealing_	the developer is here frequently, but I do think that 1.4 perhaps is a little old.
12:32	wmealing_	bordatoue, https://github.com/technomancy/leiningen/issues
12:32	KIMAvcrp	afaik util.concurrent was introduced in java 5
12:33	wmealing_	there ya go
12:34	bordatoue	i am trying to clojure with emacs , still haven't figured out how to get it working
12:35	gfredericks	bordatoue: I think all I've ever had to do is use the swank-clojure plugin
12:35	gfredericks	I'm not any good for troubleshooting though
12:36	bordatoue	could not start swank server
12:36	bordatoue	what is that about
12:37	bordatoue	could you please provide a link to the steps you have followed, I seem to be picking an old outdated one
12:38	gfredericks	https://github.com/technomancy/swank-clojure
12:38	KIMAvcrp	http://www.google.de/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0CFMQFjAA&url=http%3A%2F%2Fdev.clojure.org%2Fdisplay%2Fdoc%2FGetting%2BStarted%2Bwith%2BEmacs&ei=HanDT8XkHcLdtAbFnITdCg&usg=AFQjCNEBjHTq8rCVLevFYiWtsZXeBezzAw
12:40	KIMAvcrp	this is the recommended setup. I followed this after reinstallation of ubuntu 2 days ago and it worked out of
12:40	KIMAvcrp	the box
12:52	wmealing_	and i can assure you it works on standard rhel, nothing magical there.
12:55	peregrine81	Does clojure-ring have its own IRC channel?
12:56	gfredericks	peregrine81: not that I've heard of
12:57	peregrine81	Well I will ask here. I am trying to ring.middleware.reload but its not reloading my routes file on a new request, here is the core file. http://pastebin.com/cpvc981a
12:58	peregrine81	it never actually reloads any of my code on file change
12:58	peregrine81	or ever
12:59	peregrine81	docs for wrap-reload are pretty basic (http://mmcgrana.github.com/ring/ring.middleware.reload.html#var-wrap-reload). I tried setting directory to "src' directly I also checked to make sure the handler is truly wrapped.
13:00	gfredericks	peregrine81: so you're 100% sure that (= env "DEV") is true there, right?
13:01	gfredericks	oh I guess you just said that more or less
13:01	peregrine81	Yep I print the out the handler object and see this #<reload$wrap_reload$fn__231 ring.middleware.reload$wrap_reload$fn__231@6fbdea60>
13:01	peregrine81	so more or less yes
13:02	gfredericks	and you're running this with `lein run`?
13:02	peregrine81	I am running it with foreman and with the following command lein trampoline run -m gameapi.core
13:03	peregrine81	which drops the lein process
13:03	gfredericks	I'm not too familiar with reload. If nobody else has any suggestions, you could try pulling in the ring project with checkouts and debugging it directly
13:04	peregrine81	Well the code is pretty basic https://github.com/mmcgrana/ring/blob/master/ring-devel/src/ring/middleware/reload.clj
13:04	peregrine81	I'd just prefer not to need to reload the entire JVM everytime I change the code
13:05	peregrine81	its kinda slow :P
13:06	gfredericks	welp if it were me I'd do the checkouts thing and have it log which ns's it's reloading each time
13:06	gfredericks	might end up debugging that ns-tracker thing after that
13:06	jt123	anyone know if there's a marmalade-repo mirror out there? it seems to be down
13:07	peregrine81	could be a difference with OSX
13:39	badjer	hi, does anyone use noir and enlive together? I'm running into an issue there that seems like it would come up a lot
13:56	r0adrunner	Hi. I want to copy a directory from one place to another using clojure. How to do that?
13:57	meiji11	learn to copy a file and make a directory in clojure, and build up from there.
13:57	meiji11	that shouldn't be hard, I'm sure clojure can talk to the shell.
13:57	meiji11	the rest sounds like a good job for a finite state machine.
13:58	meiji11	in which case, I'd go with trampoline.
14:00	r0adrunner	I was looking for an one-liner. but thanks anyway
14:05	gf3	ibdknox: https://github.com/ibdknox/noir-cljs/blob/master/src/noir/cljs/core.clj#L5-6
14:26	gfredericks	r0adrunner: the fs project might have a one-liner for you
14:31	r0adrunner	gfredericks: Yes.. there is a "copy-dir" function. thanks
15:21	Bronsa	still.
15:21	Bronsa	ops, wrong chan
15:41	jsabeaudry	Elegant way to transform "BU0.003W0.322L" into [0.003 0.322] ?

15:57	borkdude	has anyone got the clojurebook near him/her, I've got a question about sorting
15:57	borkdude	on page 107: "how does clojure turn a predicate (function) into a comparator (Java Comparator)?"
15:58	borkdude	because you can do smth like ##(sort < [6 5 4])
15:58	lazybot	⇒ (4 5 6)
15:58	borkdude	but sort works with comparators which return -1,0 or 1… when I look at the source of sort, I see no transforming of the predicate into a comparator
15:59	borkdude	so, where does this happen...?
16:00	pepijndevos	borkdude: interesting... I assume fn implements it or something?

16:03	bordatoue	hi
16:04	bordatoue	is anyone having problem with marmalade-repo.org:80
16:04	bordatoue	it seems unreachable
16:05	raek	seems to be down from here (Sweden) too
16:05	pepijndevos	seems to be down for me too, but: http://www.downforeveryoneorjustme.com/marmalade-repo.org:80
16:05	bordatoue	is there any straight forward tutorial to install clojure with emacs i have spent about a week
16:05	bordatoue	nearly about to give on this
16:06	borkdude	bordatoue I think on technomancy's blog
16:06	pepijndevos	borkdude: Come to the dark side, we have vim and cookies.
16:06	pepijndevos	erm, bordatoue
16:06	raek	bordatoue: the most straight forward way (IMO) uses marmalade :(
16:06	bordatoue	but marmalade an't working
16:06	borkdude	haha
16:06	bordatoue	i can't do a package-refresh
16:07	bordatoue	please i am going crazy here
16:07	raek	bordatoue: you could donwload clojure-mode via git
16:07	raek	I have never seen marmalade down before
16:07	borkdude	I'm not laughing about your problem… about technomancy leaving again after his name is mentioed..
16:07	bordatoue	can you please check if marmalade is down
16:07	raek	bordatoue: for how long has it been down?
16:07	bordatoue	all of today
16:08	bordatoue	its all way down, when i sit in from of my mac book
16:08	raek	bordatoue: do you know how to install emacs packages without package.el?
16:08	bordatoue	no
16:08	bordatoue	as such this is complicated enough
16:09	bordatoue	is there any proxy ip i need to use
16:09	raek	bordatoue: you only need one elisp package for clojure: clojure-mode.el
16:09	pepijndevos	Isn't there some easy emacs starter bundle including clojure you can get?
16:09	raek	bordatoue: it seems to be down from here too
16:09	borkdude	pepijndevos technomancy made smth like this, but it works through marmalade
16:09	raek	it's hopefully temporary
16:09	borkdude	probably on git as well
16:09	pepijndevos	borkdude: samaaron also has one for overtone livecoding, I think
16:09	raek	bordatoue: https://github.com/technomancy/clojure-mode
16:09	bordatoue	how long have you guys using this marmalade
16:10	raek	one to two years, maybe
16:10	borkdude	bordatoue only when I installed clojure stuff, a while ago
16:10	bordatoue	that long ,
16:10	bordatoue	i just heard about it few days back
16:10	bordatoue	and when i tried it , its down
16:10	raek	bad luck :(
16:11	bordatoue	i will summarise what i had done so far
16:11	pepijndevos	https://github.com/overtone/emacs-live
16:11	bordatoue	i have installed lein
16:11	raek	bordatoue: download the clojure-mode.el file and put it in your ~/.emacs.d/ directory
16:11	bordatoue	using lein i install swank-clojure
16:11	raek	marmalade is convenient (usually), but you can install clojure-mode without it
16:11	bordatoue	so how does the repl get started
16:12	raek	bordatoue: ok, that good.
16:12	raek	bordatoue: you invoke M-x clojure-jack-in form Emacs
16:12	raek	which is provided by clojure-mode.el
16:12	borkdude	bordatoue raek you have to start it from a project though
16:13	bordatoue	when i invoke M-x i get an error, saying could not start swank server
16:13	bordatoue	do you know the cause for it
16:13	borkdude	bordatoue did you cd to a project in emacs?
16:13	bordatoue	no
16:13	borkdude	bordatoue or open a file from a project that is (I guess)
16:13	raek	bordatoue: I have an idea. could you try "M-! lein"?
16:13	bordatoue	let me explain, i used lein new myProject
16:14	bordatoue	then opened project.clj file using emacs
16:14	raek	ok, that's good
16:14	bordatoue	then typed M-x clojure-jack in
16:14	bordatoue	then it follows wit an error
16:14	raek	you should be able to use clojure-jack-in from that buffer (once everything is working)
16:14	borkdude	bordatoue did you load clojure-mode.el already
16:14	bordatoue	it says it can not start swank server
16:14	bordatoue	should i manually start the swank server
16:15	raek	bordatoue: I think emacs can't find lein. how did you put lein on the path?
16:15	raek	bordatoue: no need to do that
16:15	borkdude	bordatoue ok great, this means you don't have the swank plugin specified in the project
16:15	bordatoue	okay
16:15	borkdude	bordatoue or have you?
16:15	bordatoue	so i can add lein to my path, currently it is in /usr/bin directory
16:15	raek	bordatoue: can you try "M-! lein version"? does it return the lein version or an error?
16:15	bordatoue	which is in my path
16:16	bordatoue	wait
16:16	raek	if "M-! lein version" works, then this is not the problem
16:16	KIMAvcrp	try to run lein swank in your project directory. does it work ?
16:16	borkdude	raek I think you need to specify :plugins [[lein-swank "1.4.4"]]) in your project right?
16:17	borkdude	at least with leiningen2 if it is not in your profiles.clj
16:17	bordatoue	too much information,
16:17	raek	borkdude: if using lein2, yes (but ~/.lein/profiles.clj is a better place for it)
16:17	bordatoue	let me try one thing at a time
16:17	bordatoue	how do i check if emacs is able to see lein
16:17	raek	bordatoue: M-! lein version
16:18	bordatoue	okay i have got emacs.app
16:18	raek	you could do "M-x shell-command RET lein version" instead
16:18	bordatoue	is it Alt+!
16:18	raek	yes
16:18	raek	well
16:19	raek	alt on a PC keyboard
16:19	raek	dunno about mac
16:19	borkdude	also max
16:19	borkdude	mac
16:19	bordatoue	okay
16:19	borkdude	also called the option key (alternative, option, kind of similar words)
16:19	bordatoue	leiningen version 1.7.1 on java 1.6.029
16:19	KIMAvcrp	try to run lein swank
16:19	raek	ok, good. your lein works and emacs can find it
16:20	raek	bordatoue: how did you install swank-clojure?
16:20	bordatoue	is it the version of leinigen required
16:20	raek	bordatoue: yes, it is the latest stable
16:20	borkdude	bordatoue it matters if you work with leiningen 1 or 2, you are using 1 so this info is useful
16:20	bordatoue	i used lein plugin install swank ....
16:20	bordatoue	i used lein plugin install swank ….
16:20	bordatoue	something like that
16:20	raek	ok, that's correct for lein 1.x
16:21	raek	bordatoue: do you get any errors if you run "lein swank" in a terminal in the project directory?
16:21	bordatoue	i am not keen on leinigen 1.x i will to use any version to get it to work
16:21	bordatoue	let me try that
16:22	bordatoue	no , it seems to be downloading from the central repository
16:22	bordatoue	and finally it say connection opened on port 4005
16:22	KIMAvcrp	ok thats good
16:22	borkdude	ah
16:22	raek	ah, ok. precc control-c to kill it
16:23	KIMAvcrp	now from emacs you can do m-x slime-connect
16:23	raek	clojure-jack-in should work now
16:23	borkdude	clojure-jack-in does not force leiningen to download deps?
16:23	raek	apparently not...
16:23	borkdude	maybe this is fixed in version 2..
16:23	bordatoue	well, clojure-jack-in is throwing errors
16:23	raek	still?
16:23	borkdude	gtg
16:23	raek	bordatoue: can you post the error message somewhere?
16:24	bordatoue	okay
16:25	bordatoue	one more thing, it say cannot find project.clj
16:25	gfredericks	well that's significant
16:25	bordatoue	should i open project .clj and then use jack-in
16:25	raek	that sounds odd
16:26	bordatoue	please instruct me on what i need to do on emacs side
16:26	eighty	what is the right way to check if something is a collection?
16:26	TimMc	eighty: coll?
16:26	raek	bordatoue: the only important thing is that you run that command while visiting a file inside the project directory
16:26	KIMAvcrp	,(coll? [1 2 3])
16:26	clojurebot	true
16:26	bordatoue	okay,
16:26	bordatoue	let me do that
16:26	TimMc	eighty: Although nil can also function as one.
16:26	eighty	TimMc: nice! thanks man.
16:28	bordatoue	raek: and all others thanks, it worked
16:28	raek	bordatoue: happy hacking!
16:28	bordatoue	should i always open the project.clj file and then execute jack-in command
16:28	eighty	TimMc: nil can only function as an empty collection, right?
16:28	bordatoue	what would be the recommended way of doing this
16:29	raek	bordatoue: any file ine project is fine. I usually open a source file in src/...
16:29	bordatoue	why can't i start a repl without visiting a project
16:29	gfredericks	the repl runs in the context of a project
16:29	bordatoue	so is the repl project specific
16:30	raek	leiningen needs to know 1) what version of clojure to use 2) where your source files are and 3) what and where your dependencies are
16:30	raek	so you usually use projects for everything, including playing at the repl
16:30	KIMAvcrp	I'm beginning to port PAIP to clojure and finished chapter 2 http://kimavcrp.blogspot.de/ any recommendations about the style of the clojure code ?
16:31	bordatoue	i have got a new entry in the project.clj :plugin [lein-swank "1.4.4"]
16:31	raek	bordatoue: yes, everything (but with a few exceptions) is project specific in lein
16:31	raek	for example, you can run "lein repl" outside a project
16:31	bordatoue	from emacs shell
16:32	bordatoue	or terminal
16:32	raek	a terminal
16:32	raek	but you can't do that with clojure-jack-in
16:32	KIMAvcrp	you can also set it the inferior lisp program with (setq inferior-lis-program "lein repl")
16:32	raek	bordatoue: that entry is for lein2. lein1 will ignore it. it replaces the "lein plugin install ..." command
16:32	KIMAvcrp	then you can type M-x run-lisp to start a clojure repl everywhere
16:33	bordatoue	that is useful ,
16:34	raek	bordatoue: I always mention the slime/swank in a project approach first, since it is the most generally useful approach
16:34	dgrnbrg	hello clojurians--if I want to make a simple page in clojure that runs various shell commands when I click on links, what's the simplest way to get there (recommended tutorial/api doc)? I have programmed Grails a while ago, and I'm very proficient with Clojure
16:34	raek	if you split your code into multiple files or need to use libraries you will need it
16:34	bordatoue	many thanks,
16:40	bordatoue	i have another problem, this one mac specific . hash key is not working , alt+3 is disabled .
16:41	bordatoue	is there any other shortcuts for hash key in emacs
16:42	jsabeaudry	bordatoue, I guess that would depend on your keyboard configuration
16:45	TimMc	eighty: Right, most or all of the collection fns treat nil as empty.
16:54	KIMAvcrp	I'm beginning to port PAIP to clojure and finished chapter 2
16:54	KIMAvcrp	http://kimavcrp.blogspot.de/ any recommendations about the style of
16:54	KIMAvcrp	the clojure code ?
17:03	gfredericks	dgrnbrg: I guess noir?
17:03	dgrnbrg	gfredericks: thanks, I've been looking at it
17:04	gfredericks	dgrnbrg: without a more specific question that's the most I can say :)
17:04	dgrnbrg	I just need to expose a few shell commands through a website. The shell commands change the mode of the lighting in the room
17:06	pbostrom	is there an equivalent to something like (resolve (symbol "foo")) in Clojurescript?
17:07	gfredericks	pbostrom: don't think that's possible
17:07	KIMAvcrp	hardly without eval
17:08	pbostrom	thanks
17:08	gfredericks	pbostrom: it's hacky but you could try introspecting the ns object
17:10	pbostrom	thanks, I might read up on that, I'll probably just do something similarly hacky to do what I want
17:10	emezeske	dgrnbrg: I second the suggestion of noir, and add that you might like conch for shelling out: https://github.com/Raynes/conch
17:10	dgrnbrg	emezeske: thanks, I haven't heard of conch, i'll check it out
17:11	Raynes	Good. s_s
17:11	emezeske	:)
17:11	michaelr525	i used conch and it worked (tm)
17:11	Raynes	Woohoo!
17:12	gfredericks	that raynes. always reining.
17:21	coventry	I'm using clojure-jack-in to start slime. What does it take to get the debugging features shown in http://www.youtube.com/watch?v=d_L51ID36w4? I get the sldb window, but there is no information about local variables or pointers to my source code (e.g. the line in the backtrace for my code is "2: NO_SOURCE_FILE:1 user/eval9816"
17:24	michaelr525	so anyone here uses the eclipse debugger with clojure?
17:24	coventry	Hmm, no one's going to watch a youtube link, are they. It's not really relevant to the question. The main issue is that the backtrace in the sldb window is missing the functionality I described in the last sentence of my last message. Is this a common problem with a known fix?
17:26	peregrine81	Anyone here use lobos at all?
17:26	raek	coventry: does that video use slime or ritz (a.k.a. slime-clj)?
17:27	michaelr525	peregrine81: wuz that?
17:27	peregrine81	sql migration library for clojure
17:27	michaelr525	oh
17:28	johnmn3	hello
17:28	peregrine81	cannot seem to get the lein repl to have src/lobos in the classpath
17:28	coventry	raek: it uses slime-clj.
17:28	coventry	Should I just move to that?
17:29	raek	coventry: it's a different implementation. if you want to follow the video you need to use it.
17:29	raek	swank-clojure is more commonly used, though
17:30	coventry	OK, thanks.
17:30	raek	and it has debugging support too: https://github.com/technomancy/swank-clojure (section Debugger)
17:31	raek	http://georgejahad.com/clojure/swank-cdt.html
17:31	amalloy	coventry: ritz is definitely more full-featured. last time i tried i couldn't figure out how to install it, but that was like a year ago, so probably it's improved by now
17:32	coventry	Yes, I found it easy to install. Thanks for the pointers, this is great.
17:36	johnmn3	any more documentation out there lately on how to go about implementing reducers?
17:37	amalloy	johnmn3: i wrote a few of them, in a few different ways; i was getting feedback from rich until suddenly i stopped hearing back. so for some reducers i could tell you the definitely-right answer; for others i don't think a right answer exists yet
17:38	johnmn3	amalloy: yea, I was just reading your jira comments
17:39	amalloy	ah. well, to be honest: i totally understand why rich wouldn't want defseq in core, but it's so useful and concise that when he decides not to take it i'll put it in some other library
17:39	johnmn3	how about docs on using the existing reducers functions? for the purposes of benchmarking and whatnot? how would I go about using r/map?
17:39	michaelr525	ritz looks interesting.. i never managed to get debugging support to work with swank-clojure..
17:40	coventry	The example in the swank-cdt page raek linked works for me, but it still shows NO_SOURCE_FILE for the repl interaction and [No locals] for the local variables. It shows the debugging info for clojure core just fine, but it's my own code behaviour that I really want to inspect. How should I do this? The only way suggested in the swank-clojure readme is C-x C-e, which is what I've been using until now, and which has the same problem
17:40	coventry	with the debugger.
17:40	amalloy	johnmn3: just build clojure (mvn package), then java -jar the compiled jar
17:40	amalloy	(require '[clojure.core.reducers :as r]) (...play around...)
17:41	amalloy	or i think there's an already-built snapshot with reducers in it
17:41	amalloy	coventry: try C-c C-k to eval a whole file
17:41	johnmn3	amalloy: ah, any pointers on where to find that? I've never built clojure with mvn.. I've mostly been living in the lein world
17:42	amalloy	i dunno, the clojure snapshots repo, wherever that is
17:42	amalloy	oh wait, it's an alpha
17:42	amalloy	just depend on "1.5.0-alpha1" in your project.clj
17:43	coventry	amalloy: Yay, that's going to make life a whole lot easier. Thanks.
17:56	johnmn3	amalloy: thanks. I'm up with it now.
18:19	peregrine81	Anyway to have a function return a var? for example (defn x [] (fn [y] y)) I want x to return a var to the fn that returns y
18:19	peregrine81	its a contrived example of course.
18:20	peregrine81	Ive seen macros that just create a (def name [y] y)
18:21	peregrine81	but I'd like to return an anonymous var so I can play nice with ring handlers
18:23	kwertii	peregrine81: by "var" you mean you want a symbolic reference to the function, or are you talking about a Clojure Var (with a capital V)? and in either case, what do you mean by "anonymous var"?
18:24	peregrine81	Var, sorry
18:24	peregrine81	So I have a piece of code that returns me a function. I want to pass that into some ring middleware, but the specific ring middleware expects it to be a Var.
18:25	kwertii	peregrine81: no way to just pass it an anonymous function?
18:25	`rand`-AFK	#', maybe?
18:26	emezeske	peregrine81: What ring middleware are you using? It's totally broken if it's not okay with an anonymous handler...
18:26	peregrine81	neither of those worked. here is the bug repot I filed the ring-middleware https://github.com/mmcgrana/ring/issues/72#issuecomment-5971047
18:26	`rand`	I think there's a macro--justasec.
18:27	peregrine81	bishop/handler is defined here if interested https://github.com/tnr-global/bishop/blob/master/src/com/tnrglobal/bishop/core.clj#L118
18:27	johnmn3	is r/map parallelized?
18:27	kwertii	peregrine81: (defn foo [] (def bar (whatever)) seems to work
18:28	peregrine81	kwertii: hmm so if I patched bishop to use def instead of fn.. Lemme give it a shot
18:28	kwertii	though of course this is not exactly pure-functional
18:28	weavejester	peregrine81: You shouldn't need to patch bishop at all
18:29	weavejester	You just need to make sure that when you reload the namespace, the adapter picks up the new handler.
18:30	peregrine81	I'm not sure how to do that...
18:30	weavejester	peregrine81: Well, you just need to have your routes referenced as a var somewhere
18:30	weavejester	peregrine81: You could also just use lein-ring
18:31	weavejester	peregrine81: Your code is basically what "lein ring server" does anyway.
18:31	peregrine81	I figured
18:32	peregrine81	it would be nice if bishop/handler returned something that all the middlewares can use though
18:32	peregrine81	instead of creating a seperate var to define my routes and then my bishop/handlers
18:33	peregrine81	since I will only be using them when creating my app which only happens once
18:33	weavejester	It shouldn't be the purpose of arbitrary middleware to deal with Clojure namespace reloading.
18:34	peregrine81	is that the only middleware that expects a var?
18:34	amalloy	johnmn3: yes, if the underlying collection supports folding
18:34	johnmn3	amalloy:
18:35	johnmn3	amalloy: ok
18:35	amalloy	you can tell because (iirc) the definition of map contains (folder ...)
18:35	johnmn3	yea, for some reason my collection is: Object[]
18:35	weavejester	wrap-reload doesn't expect a var - it's just you can't supply a value directly if you want it to change when the namespace reloads.
18:35	johnmn3	when it should be a Vector
18:35	amalloy	wellll, an Object[] could be foldable, but i don't think anyone's made it be
18:36	peregrine81	weavejester gotcha
18:36	weavejester	Plus, you don't supply the var to wrap-reload
18:36	weavejester	You supply it to run-jetty
18:36	johnmn3	ah.. but a reducer is returned
18:36	johnmn3	so you have to do something like (into [] ...
18:36	weavejester	peregrine81: You could also use something like an anonymous function
18:37	weavejester	peregrine81: Anything that avoids passing the value directly, because if you do, there's nothing to reload.
18:38	peregrine81	awesome thanks weavejester !
18:38	peregrine81	again
18:38	OwenOu	hi all, what's the clojure convention of naming file and method name, are words separated by "-" instead of "_"?
18:38	weavejester	peregrine81: np - you might want to experiment at the REPL to see what works when you reload a namespace
18:38	amalloy	johnmn3: that's how all the reducers work. (r/some-transform coll) returns a new reducer; the only way to "use" its contents is to reduce over it
18:39	johnmn3	amalloy: does (into [] ... reduce over it?
18:40	amalloy	~def into
18:40	amalloy	anyway, yes. into is reduce conj, basically
18:40	johnmn3	okay
18:40	johnmn3	and do you know what reducers default chunk size is?
18:44	peregrine81	weavejester: well the lein ring doesn't quite work either, when I point it towards the base-handler I created it loads fine the first time but no reloads, even if I set :auto-reload? true
18:46	weavejester	peregrine81: I can't think why it wouldn't work. It should do.
18:47	weavejester	peregrine81: If you can provide an example project where it doesn't work, I can look into it.
18:48	peregrine81	weavejester sure! It is in pretty terrible shape cause I am learning.
18:48	johnmn3	amalloy: looks like 512
18:49	peregrine81	weavejester I wasn't really ready to push it public yet, but why not https://github.com/jeregrine/gamesapi
18:50	weavejester	peregrine81: Okay, I can't look at it tonight (UK time, so nearly midnight here), but I can try to look tomorrow.
18:50	peregrine81	weavejester perfect, hopefully I can clean it up by then. Thanks a ton!
18:53	johnmn3	well, I'm getting 14 seconds on my automaton with vanilla functions and 13 seconds with reducers, naively bolted on.
18:53	johnmn3	I think my algorithm is not tweaked for parallelization though
18:53	johnmn3	10,000 cells wide, 1,000 iterations
18:56	johnmn3	interestingly, though, r version still appears to only rev 2 of my cores. win7, quad core i7
18:56	peregrine81	now I just gotta figure out why lobos hates me
18:57	peregrine81	clojure's learning curve for the language is fairly shallow. The learning curve for libraries, lirbary usage and java is deadly steep
18:57	johnmn3	my naive implemenation of the same with pmap seems to rev 6 out of 8 threads, but runs at 16 seconds
19:14	johnmn3	yea, reducers does not appear to be using my other cores
19:15	johnmn3	is there a way to get the java version from within the repl?
19:16	johnmn3	from the command line, java -version says "1.7.0_04-ea"
19:17	johnmn3	but, from the repl:
19:17	johnmn3	test=> jsr166y.ForkJoinPool.
19:17	johnmn3	CompilerException java.lang.ClassNotFoundException: jsr166y.ForkJoinPool., compiling:(NO_SOURCE_PATH:1)
19:18	jblomo	if clojure was compiled with java 6, it will try to use jsr166y
19:18	johnmn3	yea
19:18	jblomo	the decision is made at compile time, i believe
19:18	johnmn3	I wonder if when rich said:
19:18	johnmn3	+;;todo - dynamic java 7+ detection and use
19:18	johnmn3	he meant he was using java 6 and we needed to detect java 7
19:19	johnmn3	well that complicates things
19:19	jblomo	no, i think it means when a program runs it should detect, 7 vs 6. right now, when clojure is compiled it decides
19:20	jblomo	are you compiling or using a snapshot?
19:20	johnmn3	right, so it's hardwired for java 6 with the jsr in the classpath, right now
19:24	johnmn3	I guess I could build a new lein project, paste in the reducers code, modify the fj bits to use java7, build with lein and install, and then add that to my projects dependencies...
19:29	amalloy	johnmn3: you should probably just build your own copy of clojure.jar - that's what i did when i was working on them
19:31	dnolen	hmm, what would be a good type-hint name for return values which are guaranteed to not be host false-y?
19:32	jblomo	johnmn3: agreed. it is quite simple. git clone git://github.com/clojure/clojure.git, mvn install
19:37	emezeske	dnolen: Have you considered things like AlwaysTruthy or NeverFalsey?
19:37	emezeske	dnolen: I'm trying to find a synonym for one of those, no luck yet
19:39	emezeske	dnolen: ^Axiomatic or ^Indubitable are my entries :)
19:40	dnolen	emezeske: heh, would like something short
19:40	emezeske	dnolen: ^1
19:42	jblomo	^TrueDat
19:45	dnolen	sadly ^object won't work, since 0 and "" are objects.
19:46	dnolen	^clj to denote CLJS value?
19:47	amalloy	^truthy and ^falsey?
19:48	amalloy	simple and plenty short
19:48	johnmn3	test=> (java.util.concurrent.ForkJoinPool.)
19:48	johnmn3	#<ForkJoinPool java.util.concurrent.ForkJoinPool@3a8dee36[Running, parallelism = 8, size = 0, active = 0, running = 0, steals = 0, tasks = 0, submissions = 0]>
19:48	johnmn3	still only pushes on 2 threads though
19:48	dnolen	amalloy: I don't see a use case for ^falsey.
19:49	dnolen	making ^truthy less compelling.
19:49	johnmn3	my pmap version pushes on six
19:50	johnmn3	but both parallel versions are slower than the non-par version. which may say more about my decomposition of the problem
19:50	amalloy	dnolen: what are you planning to use this for? eliminating if-tests that depend on always-true functions?
19:51	dnolen	amalloy: eliminating truth tests
19:51	dnolen	amalloy: has nothing to do w/ always true functions - just hinting that we returning a sensible value that doesn't need to be tested.
19:52	dnolen	amalloy: we're not returning 0 or ""
19:53	johnmn3	I take it back.. the reducers version is a hair faster than the non-par version
19:53	amalloy	so instead of emitting `if (cljs.core.truth(x)) ...` you want to know when you can emit `if (x) ...`? that's a sensible thing to want but doesn't seem to line up with your first question so i'm making sure i'm following
19:54	dnolen	amalloy: yes that's what we want to eliminate
19:54	amalloy	johnmn3: reducers are like 5-15 times faster in the few cases i've tested. if you're not noticing a huge speedup you're probably not actually using reducers very well
19:54	johnmn3	amalloy: that is probably the case
19:54	dnolen	amalloy: currently we can avoid that with ^boolean or ^seq which covers many cases.
19:55	johnmn3	gonna rethink the problem.. thanks for the help.. bbiab
19:55	dnolen	amalloy: but custom code which wants to really deliver host perf (like core.logic) needs something else - so we know we will only return sensible Clojure values - never 0 or ""
19:56	dnolen	amalloy: this applies to any host that allows 0 as a false-y value of course.
19:57	amalloy	^host-safe, ^testable, ^plain, ...
19:58	dnolen	amalloy: naming is hard
19:58	amalloy	indeed. that's why i'm spewing bad names and hoping you'll decide one is good
19:59	amalloy	what about just ^if-safe - it's short-ish, and describes exactly the technical quality you're indicating
20:08	mmarczyk	dnolen: hi! more fantastic improvements to cljs during EuroClojure, I see :-)
20:10	dnolen	mmarczyk: hullo!
20:10	dnolen	mmarczyk: yes got some new ideas :)
20:10	mmarczyk	dnolen: :-)
20:13	jblomo	what is the gvec.clj used for?
20:14	mmarczyk	jblomo: vector-of
20:15	mmarczyk	jblomo: vectors of primitives, that is
20:15	dnolen	mmarczyk: I think that ensuring that no ops are much more than > 2X slower than Clojure on the JVM for V8 is a realistic goal.
20:15	jblomo	ah cool. i saw vectors of primitives, but didn't connect with that function. thanks
20:16	mmarczyk	dnolen: that is amazing
20:17	dnolen	mmarczyk: yes, anything that takes longer than 100ms for 1000000 iterations in the benchmarks means we're not doing enough.
20:18	emezeske	dnolen: That's a really aggressive goal. I love it!
20:19	mmarczyk	dnolen: right -- must get our act together on those cases -- can't wait to do just that :-D
20:19	mmarczyk	dnolen: so, do you have any particular roadmap in mind?
20:20	dnolen	mmarczyk: right now pondering higher order fn invocation.
20:20	mmarczyk	(incidentally, one thing I've wanted to do for a while -- cache hashing on records -- patch @ CLJS-281)
20:25	dnolen	mmarczyk: nice looking now.
20:28	dnolen	mmarczyk: applied
20:28	mmarczyk	dnolen: cool, thanks :-)
20:30	dnolen	mmarczyk: chunked seqs are bizarrely slow ATM, so I created array-reduce - but I haven't integrated it yet with ChunkedCons or ChunkedSeq
20:31	mmarczyk	dnolen: I'll look into it then
20:32	dnolen	mmarczyk: cool! thx
20:32	dnolen	mmarczyk: one of the largest bottelnecks was eliminated with INext
20:33	dnolen	mmarczyk: optional protocol for much faster iteration - since the logic of whether to return nil or () can be in the collection .
20:33	mmarczyk	dnolen: looking at the INext patches now actually -- great stuff
20:37	dnolen	mmarczyk: oh forgot to mention the big problem really was that because next had so many nested tests Closure wasn't lifting fns.
20:39	mmarczyk	dnolen: interesting
20:39	mmarczyk	dnolen: hence CLJS-277, right?
20:40	dnolen	mmarczyk: yes, I don't think there are many cases but we should remove them and pay attention to introducing them - if it didn't lift/unwrap with simple optimizations then it won't at all.
20:40	mmarczyk	dnolen: good to know
20:40	dnolen	mmarczyk: I was extra happy to remove coercive-not and coercive-=
20:41	mmarczyk	dnolen: oh yeah!
20:41	dnolen	mmarczyk: also seq, next and rest are type-hinted now that means no pointless truth tests for common pattern.
20:41	mmarczyk	dnolen: I seem to recall there was a place in the code where undefined use to come up in arrays
20:41	mmarczyk	dnolen: but it doesn't now
20:41	mmarczyk	dnolen: any idea as to what might have fixed that? (or am I misremembering sth?)
20:42	dnolen	mmarczyk: yes nil? was poorly defined.
20:42	dnolen	mmarczyk: nil? is the one place where we need coercive-=
20:42	mmarczyk	dnolen: ah, I see
20:43	dnolen	mmarczyk: it used be based on identical? which caused the problems.
20:43	mmarczyk	dnolen: makes sense
20:45	mmarczyk	dnolen: re: 0e0aa7fdd -- is peek/pop slower than first/next now?
20:46	dnolen	mmarczyk: the issue was just that pop can return ().
20:46	dnolen	mmarczyk: switched to first/next to follow rhickey's version and avoid seq call.
20:47	mmarczyk	dnolen: I see, thanks
22:17	wolkefm	Hello all - I'm picking up a new machine tomarrow (thinkpad t410) and going to buy one of the clojure books - I've minimal lisp experience and I would say that I'm an incredibly inexperienced programmer. What books would you recoomed knowing my intent is to develop a swing application?
22:17	wolkefm	*reccomend
22:21	tmciver	wolkefm: I didn't have much lisp experience when I started clojure and I read Halloway's 'Programming Clojure' which I think is an excellent book for a beginner. I have the first edition, which is now a little dated, but I recommend the second edition.
22:22	tmciver	'Clojure Programming' is a new book that is also excellent but I think might be a little fast-paced for someone with no lisp experience.
22:24	wolkefm	I might as well grab both I suppose. I've no job with nothing but time on my hands to make plenty of mistakes. I was also thinking about grabbing 'the joy of clojure'. I remember reading somewhere that it is 'the rabbit hole' or somthing to that effect
22:30	ivan	wolkefm: I really like Joy of Clojure but it is an advanced book with compressed explanations
22:40	wolkefm	Noted.
23:20	johnmn3	so, I'm trying to figure out how to split out work for parallel execution
23:21	johnmn3	and so I'm breaking work up in to managable chunks:
23:21	johnmn3	(defn chunk [coll size] ...)
23:21	johnmn3	(chunk [1 2 3 4 5 6] 3)
23:21	johnmn3	-> [[1 2 3][3 4 5][6 7 8]]
23:21	johnmn3	Can I get what I want with reducers? : (into [] (r/flatten (r/map #(map inc %) (chunk [1 2 3 4 5 6 7 8]] 3))))
23:33	jblomo	reducers will automatically split up the datastructure, so you shouldn't have to do it manually
23:33	jblomo	if you do want to split up a vector like that, take a look at partition
23:33	jblomo	johnmn3: ^
23:46	johnmn3	jblomo: thanks
23:47	johnmn3	what about: (into [] (flatten (pmap #(map inc %) (chunk [1 2 3 4 5 6 7 8]] 3))))
23:48	johnmn3	will pmap finish incing the whole collection faster for large collections?
23:49	jblomo	pmap is semi lazy. it tries to stay ahead of the consumer while using all cores
23:49	jblomo	however, there's a cost to coordinating across threads. pmap is only worth it if your function is relatively expensive
23:49	johnmn3	it appears that inc is too easy gets very little benefit from parallel
23:50	jblomo	probably
23:50	johnmn3	I still don't get that though
23:51	johnmn3	cause if I make my coll 10,000 wide and my window 100 wide
23:51	johnmn3	my chunking window.
23:51	johnmn3	you'd think a larger chunk size -- 1000, for instance -- would make the job more epensive
23:51	johnmn3	expensive
23:52	johnmn3	so just increase the window and apply it to a larger data set and we should see savings, I'd think.
23:52	johnmn3	but I'm not seeing it.
23:54	jblomo	inc'ing 1000 integers is going to take like 50 usec
23:54	jblomo	to test it out, you may want to make a sleeper function
23:55	jblomo	something that just sleeps for a 50 msec or something
23:55	johnmn3	inc'ing 20,000 integers with window of 100 takes 7 seconds
23:56	johnmn3	same parallel as non-parallel though. 7 seconds
23:56	jblomo	how are you running those tests?
23:56	johnmn3	that's twenty chunks though.
23:57	johnmn3	(defn pfn [afn arange awindow](into [] (flatten (pmap #(map afn %) (chunkify (range 1 arange) awindow)))))
23:58	johnmn3	(let [_ (time (pfn inc 20000 100))] (println "done"))
23:59	johnmn3	oh, chunkify is a little messy
23:59	johnmn3	where's the clojure pastebin?
23:59	jblomo	wwnot sure. i usually just use github gists
23:59	jblomo	buti don't have chunkify
