#clojure – 2011-06-20

2011-06-20

02:23	tsdh	Hi
02:23	tsdh	What's the right tool to generate API documentation for clojure projects?
02:25	tsdh	Till now, I've tried autotdoc-0.7.1 which fails downloading its deps, and com.fxtlabs/autodoc "0.8.0-SNAPSHOT", which fails when running "lein autodoc". I use clojure-1.3 in my project, which might be the reason for the latter.
02:27	raek	I'm currently using [org.clojars.rayne/autodoc "0.8.0-SNAPSHOT"]
02:27	raek	it is the only verision I got working
02:28	tsdh	raek: Thanks, I'll try that.
02:28	raek	tsdh: you might need to clean the lib/ directory manually
02:29	raek	I think one "bad" version of autodoc adds something that breaks lein
02:29	raek	(I used clojure 1.2.1 in the project)
02:32	tsdh	No, doesn't work (even after cleaning lib/ and lib/dev): java.lang.NoSuchMethodError: clojure.lang.KeywordLookupSite.<init>(ILclojure/lang/Keyword;)V
02:39	tsdh	In a project.clj file, how can I specify that I need foolib in version 0.2.0 or newer?
02:40	raek	"[0.2.0,)", I think
02:40	raek	http://maven.apache.org/plugins/maven-enforcer-plugin/rules/versionRanges.html
02:41	tsdh	raek: Ah, yeah, I've missed the comma. :-)
03:10	Scriptor	hi everyone, so as I understand it, internally Clojure uses copy-on-write for some sequences while they're still small
03:10	Scriptor	but then converts them to true persistent structures after a certain point, is that right?
03:13	raek	,(class {:a 1, :b 2})
03:13	clojurebot	clojure.lang.PersistentArrayMap
03:14	raek	iirc, ArrayMaps (which search linearly throught an array) are used for 8 or less entries
03:14	Scriptor	ah, nice
03:14	Scriptor	,(class [1 2 3])
03:14	clojurebot	clojure.lang.PersistentVector
03:15	raek	for persistent vectors the branching factor is 32, which basically means you get copy-on-write for vectors up to 32 elements
03:15	Scriptor	right, I remember reading about that, it keeps that 32-element array for performance reasons
03:28	Scriptor	hmm, I wonder why arraycopy is under System
03:40	no_mind	there was a function that will let you check the type of a var. Cannot recall its name
03:43	raek	no_mind: what do you mean by "the type of a var"? it's :tag metadata?
03:43	raek	or the type of the value it contains?
03:43	no_mind	nah (type a)
03:44	no_mind	raek: yes, type of value
03:46	raek	class is the more basic form
03:46	clojurebot	Ok.
03:47	raek	the type function simply does this (defn type [x] (or (:type (meta x)) (class x)))
03:48	raek	it was used to emulate types in the time before records
03:51	Cozey	Hello - I am aot-compiling one clj file to be a ring servlet - I'm using cake, and it generates *.class files for clojure dependencies of the project - should this be so? I'd like to keep the dependencies in separate jar files, not bundled in war together with my app.
04:13	Cozey	hmm. what's the status of http://dev.clojure.org/jira/browse/CLJ-322 ? - this basically is my problem, but the resolution is still in progress
04:28	raek	I know Leiningen has a workaround for it.
04:28	raek	but it's a shame that issue hasn't been fixed yet
04:41	Cozey	and cake ?
04:41	Cozey	eh! only lein supports swank-cdt, only lein workarounds this one... should I migrate to it from cake?
04:51	TobiasRaeder	Morning
04:52	bsteuber	Moin
04:54	__name__	moin
08:23	Bronsa	(defmacro my-if [test t f] `(([(fn [] ~t) (fn [] ~f)] ~(#({true 0 false 1} test)))))
08:23	Bronsa	:D
08:57	schani	why is (seq? [1 2 3]) false?
08:59	stuartsierra	a Vector is not a Seq
08:59	schani	yet it responds to first and rest
09:00	stuartsierra	yes
09:00	schani	is there a predicate for whether something can be firsted and rested?
09:00	stuartsierra	it's Seqable.
09:01	stuartsierra	`seqential?`
09:01	schani	ah, awesome!
09:02	schani	ok, then follow up question: why would i care whether something is actually 'seq?', rather than 'sequable?' ?
09:03	ebaxt	Hi, I've been trying to figure out what the idiomatic way to 'change' an element in a vector is when you don't know the index of the element. Is map the only option?
09:05	schani	ebaxt: i'd find out its index first and then do an assoc
09:06	ebaxt	schani: ok, thanks.
10:50	shtutgart	Hi. If I'll return random number from macros, it'll be unique for each compilation, right?
10:54	manutter	shtutgart: what do you mean by "return random numbers from macros"?
10:56	shtutgart	manutter: (defmacro rnd [] (rand-int 10)), then (defn foo [] (rnd))
10:57	shtutgart	now (foo) should return unique number for each compilation?
10:59	raek	shtutgart: yes, it will be unique for each place where foo is expanded
11:00	raek	(defmacro duplicate [expr] [expr expr])
11:01	raek	(duplicate (foo)) --> [(foo) (foo)] --> [3 4]
11:01	shtutgart	raek: i guess you mean rnd, not foo
11:02	raek	...but it is considered bad for a macro to behave as my duplicate
11:02	raek	shtutgart: sorry, yes. that is what I meant... :)
11:03	raek	(defmacro good-duplicate [expr] `(let [x# ~expr] [x# x#]))
11:04	shtutgart	ok :) just wanted to make sure i understand everything correctly. So macros is always expanded before compilation and can't be expanded in runtime
11:04	shtutgart	(except eval)
11:05	raek	shtutgart: yes.
11:06	shtutgart	ok, thanks!
11:06	raek	...and the result of a macro is sent for expansion again
11:17	ilyak	hi *
11:17	ilyak	What's the best way to create a bean class in clojure?
11:18	ilyak	bean class is something with a bunch of setters and an (atom {}) inside
11:18	ilyak	for use with e. g. spring
11:19	shtutgart	bean fn from clojure.core returns immutable map, so probably you have to write your own function using reflection api
11:21	ilyak	No, bean fn is cool
11:21	chouser	ilyak: deftype, as long as you have interfaces to implement
11:21	chouser	or reify
11:21	ilyak	The problem is getting the java object to bean
11:22	ilyak	chouser: I don't want to write the state-management code myself so I'm looking for an existing solution
11:22	ilyak	because otherwise it's pretty trivial - :gen-class and stuff
11:22	ilyak	However, no point of writing that code if it's already there
11:22	chouser	using :gen-class is trivial? whew!
11:24	chouser	ilyak: you want to just list your properties and have something generate your getters and setters that manipulate a map in an atom?
11:24	ilyak	chouser: Yeah, something like that
11:24	ilyak	I'd like to specify what setters/getters I want and get them for free
11:25	chouser	I don't think I've seen anything like that. Might be a fun macro to write, though. :-)
11:36	ilyak	If I have a github gist, how would I figure out its parent project?
11:39	chouser	I didn't know gists had parent projects
11:40	manutter	I think some do and some don't
11:41	manutter	I've created "anonymous" gists with no related projects, so I know they don't necessarily have parent projects
11:42	edoloughlin	[org.apache.geronimo.configs/javamail "2.2.1"] in my project.clj pulls down the whole Geronimo dist. Is there a better way?
12:00	naeu	has anyone else noticed slime+swank really struggling to println data structures such as a simple vector?
12:00	naeu	(dotimes [x 300] (println ["hi" x])) really destroys my machine and freezes emacs
12:00	naeu	whereas in a cake repl, it's pretty much instantaneous
12:04	Scriptor	naeu: works fine for me
12:04	naeu	Scriptor: does it print out instantaneously?
12:04	Scriptor	naeu: just about
12:04	manutter	same here
12:04	naeu	can you try 1000?
12:04	Scriptor	I can go up to 3000 without a problem
12:04	naeu	oh wow
12:04	naeu	i'm jealous!
12:05	naeu	i'm wondering where my bottle neck is
12:05	naeu	which versions of slime and swank are you using?
12:05	manutter	naeu: is this something you've just noticed, or is it always that way?
12:05	Scriptor	running xp on macbook intel core 2 duos
12:05	Scriptor	*duo
12:05	naeu	manutter: it's been this way for a while
12:06	naeu	i have a very beefy machine - macbook pro core 2 i7 2.8GHz
12:06	manutter	have you seen technomancy's blog post on the super-simple way to set up swank and emacs?
12:06	naeu	yeah, but i use cake
12:06	Scriptor	naeu: do you get the same problem if you do the same in the repl in the shell?
12:06	manutter	ah
12:06	naeu	but i've tried both lein and cake and see the same results - so its not the build tool that's the issue
12:06	naeu	Scriptor: in the repl, it's instantaneous
12:07	naeu	it's just in emacs
12:07	Scriptor	damn, and as far as you know it's the latest swank-clojure?
12:07	manutter	if I were you I'd still be tempted to clean out my old emacs setup and re-install using the clojure-jack-in stuff
12:08	manutter	well, back up the old stuff and THEN clean it out, of course ;)
12:08	naeu	manutter: clojure-jack-in only works with lein though, and i need cake for my native deps
12:09	technomancy	naeu: leiningen from git should work with native deps
12:09	naeu	technomancy: cool - nice work
12:09	naeu	although to be honest, i really don't think it's either lein or cake that's the issue here
12:10	technomancy	sure, just throwing that out there. it hasn't seen a lot of use anyway since native-deps are pretty rare. what's the specific dependency?
12:10	naeu	printing via the repl is super fast, just with emacs
12:10	technomancy	it's fast here with jack-in, otherwise I'd blame a lack of byte-compilation
12:10	naeu	erm, i meant it's just with emacs that i'm seeing the issue
12:11	naeu	technomancy: what does jack-in offer for the slime communication that standard swank<->slime doesn't offer?
12:11	naeu	or does it just set them up for you?
12:11	naeu	I'm running swank 1.4.0-SNAPSHOT and the latest slime from technomancy/slime on github with emacs 23.3.1
12:13	naeu	i've tried downgrading to swank 1.3.0 and still see the issue
12:13	naeu	i've tried both terminal and GUI versions of emacs and still see the issue
12:14	naeu	basically emacs rams up to 100% cpu usage as it churns and churns to print out stuff
12:14	technomancy	naeu: the main advantage is it's just easier to install and it picks a port for you
12:14	naeu	technomancy: that sounds lovely, but i don't think it will resolve my issue
12:14	naeu	unless there's some config i'm missing?
12:15	technomancy	naeu: probably not. maybe try another distribution of Emacs? See if it happens in -nw, try compiling 24, etc.
12:15	naeu	technomancy: I've tried two separately compiled versions of emacs
12:15	naeu	but both 23.3
12:16	naeu	hang on, maybe it's this durendal stuff i'm using?
12:16	naeu	i use durendal to highlight the repl
12:16	technomancy	try it with emacs -Q too; relaunch and eval-buffer in slime.el
12:17	naeu	what does -Q do?
12:17	technomancy	oh, that would be my guess.
12:17	technomancy	-Q skips all dotfiles
12:17	naeu	ah, useful
12:17	naeu	i'm going to try without durendal
12:17	naeu	i didn't think of that
12:17	naeu	here's how i plug slime in though, in case this is way off: https://github.com/samaaron/dot-emacs/blob/master/live-config/slime-conf.el
12:18	technomancy	whaaa
12:18	technomancy	wait, are you saam aaron?
12:19	technomancy	whoever wrote that doesn't understand what eval-after-load is for
12:19	naeu	technomancy: yep, i'm sam
12:19	technomancy	oh, hi =)
12:19	naeu	and i don't understand what eval-after-load is :-)
12:19	naeu	you're right!
12:19	naeu	and hi! :-)
12:19	technomancy	it's basically to set a hook to be eval'd after a given feature is loaded
12:20	naeu	i'm still learning emacs (it's a long slow rocky road)
12:20	technomancy	so having both eval-after-load 'slime and require 'slime in the same file is redundant
12:20	naeu	ah cool
12:20	naeu	which is idiomatic emacs lisp?
12:20	technomancy	you can use it to improve Emacs boot time if there are features you're not going to be using in every Emacs launch
12:21	naeu	ok, so that still doesn't make total sense to me
12:22	technomancy	"by the way, if you do happen to load slime at some point, here's some stuff you should do once it's loaded"
12:22	naeu	it seems that i'm usign eval-after-load 'slime to add two callbacks: slime setup and a statement to ignore versions
12:22	technomancy	it's a lot like add-hook, but it works in terms of require rather than individual defuns
12:22	naeu	i then require slime which i assume loads it?
12:22	technomancy	yup, so it's not really deferred at all
12:22	technomancy	also: setq is safe to do before slime loads anyway
12:22	naeu	if it's similar to ruby's require which loads once only like a defonce
12:22	technomancy	yup
12:23	technomancy	also you could collapse the two slime-setup clauses
12:23	naeu	yeah, i see that now
12:23	naeu	can i combine with a do or does emacs lisp have a different form for combining things?
12:24	naeu	i've basically avoided learning emacs lisp as much as possible as to not confuse learning clojure
12:24	technomancy	for slime-setup in particular you can just add combine the two argument lists
12:24	technomancy	do is progn in elisp/cl
12:24	naeu	but now i'm pretty confident with clojure i feel i can branch out a little
12:26	naeu	so would this be a good clean-up: https://gist.github.com/1035929
12:26	technomancy	just move the slime-setup to after the require and you shouldn't need eval-after-load
12:27	technomancy	but yeah, looks better
12:27	naeu	refresh it again
12:28	technomancy	thumbs up
12:28	naeu	cool, thanks
12:28	technomancy	np
12:28	naeu	i really would benefit from working closely from someone that groks emacs
12:28	naeu	:-)
12:28	naeu	one day maybe
12:28	technomancy	one thing at a time I guess
12:29	naeu	absolutely
12:29	naeu	i feel fairly proficient with it now
12:29	naeu	which is a huge relief given the amount of work i've put into it :-)
12:29	technomancy	I have the benefit of having learned elisp first, so when I go back it just feels quaint. to someone who knows clojure, picking up elisp afresh would probably seem pretty backwards.
12:30	mrBliss	but now slime is loaded immediately, not 'autoloaded'?
12:30	naeu	ok, so it's definitely the durendal stuff that's killing me
12:30	naeu	how annoying - i like having a coloured repl
12:31	naeu	technomancy: yeah, it definitely seems backwards
12:31	naeu	i was playing around with regexps the other day - horrrrrrrible!
12:31	technomancy	=(
12:32	naeu	does emacs support the notion of contexts for highlighting?
12:32	technomancy	you can narrow the buffer down
12:32	naeu	i.e. if i'm in context A and I see regexp R then it means so and so
12:32	technomancy	but I don't think there are first-class parsing contexts
12:32	naeu	whereas if I see regexp R in context B it means something else?
12:32	technomancy	not really
12:32	naeu	that sucks
12:33	technomancy	a friend of mine is working on a framework for building modes with real composable peg parsers
12:33	naeu	TextMate had that better I think
12:33	naeu	that sounds great
12:34	technomancy	it's only in Emacs 21 that syntax highlighting was even turned on by default; back in the day it was seen as a resource hog.
12:34	naeu	haha
12:34	naeu	well, it's clearly a resource hog in my repl
12:34	technomancy	"luxury!"</yorkshiremen>
12:34	technomancy	good point
12:35	offby1	you try telling that to today's young people ...
12:35	naeu	:-)
12:36	naeu	technomancy: so have you played with overtone yet?
12:36	technomancy	not yet, though once lein 1.6 is out I may give it a run. sounds like fun.
12:36	naeu	have you done much dsp stuff?
12:37	technomancy	nothing whatsoever
12:37	naeu	it's been a complete headfuck for me to understand
12:37	technomancy	my "digital art" explorations have so far been limited to a handful of Processing sketches
12:37	naeu	however, we're pretty much at the stage of working at higher level abstractions now
12:38	naeu	so the dsp stuff can be done by dsp-boffs and higher level musical structures can be written to trigger the audio
12:39	naeu	right now overtone is cool for people that know clojure and supercollider
12:39	naeu	which is basically 5 people in the world
12:39	naeu	which is pretty useless
12:39	naeu	so we're really working to make it much more accessible and usable
12:40	naeu	the first audience with be people that know clojure and don't know supercollider
12:40	naeu	and then we'll move to musicians in general
12:40	technomancy	heh; sweet
12:40	technomancy	processing seems to have some good ideas re: making programmatic art accessible
12:40	naeu	processing is very nice
12:40	technomancy	shame about the syntax =)
12:40	naeu	haha
12:41	naeu	that's the great thing about lisps - syntax is not really an issue
12:41	naeu	you can always hof or macro your way out of horrible places
12:41	technomancy	if you're targetting non-programmers you can skip a lot of the "forget everything you know about programming" stage; I imagine that could save a lot of time
12:42	naeu	i'm also very excited to see how much leverage Clojure's concurrency stuff for music structure
12:42	ejackson	technomancy: are you implying that artists don't know anything :P ?
12:42	naeu	i believe it will be particularly useful to coordinate multiple 'band-member's' activities
12:43	naeu	technomancy: the big question is "how much programming knowledge is necessary to write music with computers?"
12:43	naeu	I believe it's probably a fair bit more than we'd like
12:44	Scriptor	naeu: As in composing regular music?
12:44	naeu	Scriptor: it depends on what you mean by regular :-)
12:45	naeu	i think if you stick to the declarative notation that is the standard Western Common Notation - then probably no programming knowledge is necessary
12:45	Scriptor	one of the programs that don't require you to directly use a programming language
12:45	naeu	however, that seems soooo limited when we have logic and other interesting notational semantics at our fingertips
12:46	naeu	i want to be able to say "occasionally, if thing is doing something over there, and this other thing is doing that, then do something special"
12:47	Scriptor	hmm, that's a neat way to look at music
12:47	Scriptor	almost like an event-based pattern
12:47	naeu	Scriptor: i see it as a big coordination task
12:47	naeu	Scriptor: absolutely, that's a nice way of thinking about it
12:47	Scriptor	naeu: well, as far as I know it's layering different sounds up on each other and logic thinking like that is mainly done in the head
12:47	naeu	but it's also only one way, i want to have multiple ways of expressing my composition
12:48	Scriptor	so that if you want something special to be done, you have to write it in yourself
12:48	ejackson	naeu: when you can make jazz, you have succeeded !
12:48	naeu	Scriptor: exactly - and wouldn't it be cool if you could improvise those thoughts
12:48	naeu	if you had a magic music repl to try out your ideas
12:48	Scriptor	naeu: wait, are we talking about generating music or better ways to write music yourself?
12:48	Scriptor	oh
12:49	Scriptor	there's a live music thing that uses a lisp dialect
12:49	naeu	Scriptor: both - although i'm personally less interested in generating music, rather using software to augment a performer
12:49	naeu	Scriptor: yeah, there's at least two - Common Music and Impromptu
12:50	naeu	Common Music is in CL and provides many high order functions for manipulating music concepts but typically generates midi output
12:50	naeu	Impromptu rocks but is Mac only, relies on Core Audio and isn't open source
12:51	naeu	Overtone is built with Clojure and uses SuperCollider for audio synthesis and is totally open source
12:52	naeu	and after spending a good while with Clojure, both Scheme and CL seem a bit backwards
12:53	naeu	oh yeah, I forgot to mention that Impromptu is written in a Scheme
12:53	naeu	one thing Impromptu does have is a pauseless GC - which is the only real pain running on the JVM
12:53	Scriptor	I think Clojure is spoiling me in some ways, CL and Scheme just seem much less appealing
12:54	Scriptor	naeu: does it use Racket or its own implementation?
12:54	naeu	Scriptor: it's own impl
12:54	naeu	or at least major parts are bespokely written
12:54	ejackson	naeu: have you seen the pauseless GC stuff that Azul are hawing ?
12:55	naeu	ejackson: yeah, i've read about it whilst drooling
12:55	ejackson	me2
12:55	ejackson	naeu: they might spot you a freebie for marketing porpoises
12:55	naeu	ejackson: that would be nice, but i want to make a platform anyone can use for free
12:56	naeu	I want Overtone to be easy to hack on and easy to make music with
12:56	naeu	currently I'm working on making Overtone easy to hack on
12:56	ejackson	naeu: sure, of course, anybody can still hack on it, but a performer can then get the Azul JVM and perform w/o pauses.
12:56	naeu	ejackson: yeah, that's true
12:57	ejackson	as i understand you just switch out the JVM be
12:57	naeu	i wonder if anyone has had any success runnign clojure on the Azul JVM
12:57	ejackson	anyway, the only instrument I can play is the fool, so I'll just move along.
12:58	naeu	ejackson: we'll have you rocking a REPL somepoint in the future
12:58	ejackson	heh.
12:58	Scriptor	naeu: what's the best way to learn overtone right now?
12:59	naeu	Scriptor: come to Cambridge and hang out with me :-)
12:59	naeu	haha
12:59	naeu	actually that's an excellent question
12:59	Scriptor	cambridge, MA or England? :p
12:59	naeu	with no simple answer, unfortunately
12:59	naeu	Scriptor: the original Cambridge
12:59	naeu	none of your American name-reuse garbage
13:00	naeu	:-p
13:00	naeu	they could have at least prefixed the name to stop clashes like they did with York and Orleans
13:00	ejackson	Cherry Flavoured Cambridge (actually I was there just last week, and in Original this week)
13:01	Scriptor	heh, sounds good, I'll check out the screencast then
13:01	naeu	yeah, there are a few screencasts out there now
13:01	naeu	and I'm working on more
13:01	naeu	http://vimeo.com/22798433
13:01	naeu	http://vimeo.com/25190186
13:01	naeu	http://vimeo.com/25102399
13:02	naeu	but the last two won't be useful if you've already worked on Clojure projects before
13:02	Scriptor	which I haven't, cheers!
13:02	naeu	oh, then they should be pretty useful then
13:02	naeu	the first is how to set up clojure with emacs
13:02	naeu	the second is how to work on edge Overtone
13:03	naeu	you should also join the mailing list: http://groups.google.com/group/overtone
13:03	naeu	that's the best place to have your questions answered
13:04	naeu	and we're looking for beginner questions right now: "How do I make a simple synth?" "How to I make a basic beat?" etc.
13:04	Scriptor	awesome, I'll check it out
13:04	naeu	recently I've been spending a whole heap of time working on the guts
13:04	naeu	and it's starting to get pretty rock solid now
13:04	Scriptor	I need to find something solid to start hacking with clojure on
13:05	naeu	Scriptor: well this is something fun and engaging to work with
13:05	naeu	which i think is an excellent plaground for learning a new language
13:05	naeu	it's so much nicer to say "hey, i made it play c major!" than "hey, I sorted this list!"
13:07	Scriptor	naeu: should be good, my musical brain cells have been collecting dust for years
13:07	pdk	i knew one guy who went off to columbia U
13:07	pdk	made a music programming language there
13:07	naeu	pdk: nice, do you know the name of the lang?
13:07	pdk	it could go places as a teaching tool
13:07	pdk	nah he just mentioned it in conversation when he came back here to visit for graduation
13:08	pdk	and this was a project for a compilers course so you might have already eclipsed it :p
13:10	pdk	are you going to have a console version of this you can interact with in clojure code or is it focusing on gui
13:10	pdk	yknow what would be neat actually
13:10	pdk	drag and drop clojure
13:10	pdk	since its already a tree format basically
13:10	Scriptor	like a visual languag?
13:11	pdk	not so much a new language but
13:11	pdk	since it's already putting code in nested structures
13:11	pdk	picture dragging () into a scratch area to start
13:11	pdk	then dragging and dropping parts of forms into the middle of the () to add to it
13:12	pdk	like drag () onto scratch, drag print onto scratch and it pops up "enter arguments" and you'd type text or get another scratch area to nest forms into the print
13:12	pdk	also is this using midi or does it come with instruments prerecorded
13:13	pdk	and is the blur on the text from recording it with a camera?
13:14	Scriptor	quick java-ish question, when you implement the interfaces that make an object work like an array, will that object be able to work on any method that takes arrays for input?
13:15	pdk	are we talking ArrayList
13:15	Scriptor	I think
13:15	pdk	ArrayList<type> arrays are distinct from type[] arrays
13:16	Scriptor	ah, got it
13:18	dsesclei	Hello. I'm working on a Clojure REPL applet. In Chrome and Safari, it works the first time it is loaded, but fails if the page is refreshed and won't work again until the browser is restarted. If two tabs are opened to the applet, however, it will work fine when the page is refreshed. I'm guessing this is a problem with caching, but not really sure how to solve it. Does anyone here have an idea?
13:18	dsesclei	H
13:18	dsesclei	Here's the applet: http://66.228.47.25/applet.html
13:19	naeu	pdk: initially a console version - and eventually a GUI
13:19	naeu	pdk: there's already a nice block diagram version of scheme used for music programming
13:20	naeu	pdk: and midi is crazy old skool. The new cool is osc - open sound control, and Overtone supports both. Plus it lets you design and build your own synths using Clojure forms.
13:21	naeu	So you can use Overtone to drive midi/osc devices as well as using it to build and control your own synthesisers
13:21	pdk	how's overtone for cross platform compat
13:22	pdk	especially considering the situation with linux sound does it make that a bit less thorny for the programmer
13:22	pdk	also do you have an idea in mind for how the gui would work
13:22	naeu	pdk, works out of the box with linux and mac, windows support is there, but a bit cobwebby
13:22	pdk	something like dragging little icons that represent the forms you wrote onto musical bars?
13:22	naeu	pdk: we have a lot of ideas, but really could do with some hacking support
13:23	naeu	we're thinking of using JavaFX 2.0 when it stops being windows only
13:23	pdk	is this a team uni project now
13:23	naeu	pdk: is Overtone a team uni project?
13:24	pdk	clojure music
13:24	naeu	i don't understand the question, sorry
13:24	pdk	the project you're doing
13:25	naeu	Overtone is an open source project initiated by Jeff Rose
13:25	naeu	I hack on it quite a bit whist at uni (I'm doing a postdoc)
13:26	naeu	so it's not really a uni project
13:26	naeu	although it's mainly hacked on by people at uni
13:26	naeu	but it doesn't have any specific funding etc.
13:26	naeu	pdk: if you have any cool GUI ideas, you should totally join the mailing list and get involved
13:26	naeu	http://groups.google.com/group/overtone
13:27	naeu	right, i'm off out now. Take good care everyone
13:36	Scriptor	are just about all the seq functions implemented using straight clojure, without java interop?
13:37	dnolen	Scriptor: ?
13:40	chouser	Scriptor: most of the higher-level ones, yes. Ones like first, rest, and lazy-seq interact directly with Java classes via interop
13:41	Scriptor	dnolen: just looking at the functions listed on http://clojure.org/sequences#Sequences-The%20Seq%20library-Creating%20a%20seq
13:42	Scriptor	does java not have its own partition function?
13:45	chouser	Scriptor: if it did, it couldn't consume/produce Clojure lazy sequences, could it?
13:46	Scriptor	chouser: right, forgot about that
13:48	Scriptor	alright, time to implement them all
13:49	chouser	what!?
13:50	Scriptor	;)
13:51	chouser	implement all the seq functions? why?
13:53	Scriptor	a good number at least, for a lisp I'm working on
13:53	chouser	ah
13:54	chouser	Why not just use Clojure? (not a rhetorical question)
13:56	Scriptor	chouser: it has its own nice, sorta, but a deal of it is for fun
13:56	chouser	it's own "nice"?
13:56	Scriptor	argh, *niche
13:56	Scriptor	otherwise, once I figure out my next project I'll be using clojure
13:57	chouser	heh, ah. I understand "for fun". What about the niche makes Clojure a poor fit?
13:57	Scriptor	not easy to make it work with a php codebase :D
13:58	chouser	so if Clojure compiled to PHP ...?
13:59	Scriptor	chouser: well, this compiles to PHP, but it's not quite Clojure
13:59	Scriptor	http://scriptor.github.com/pharen/ if you're curious
13:59	chouser	What I'm asking is, if Clojure could compile to PHP would the only reason remaining to create your own lisp be "for fun"?
14:00	Scriptor	chouser: exactly
14:00	chouser	ok!
14:01	Scriptor	damnit, now I have competition
14:02	chouser	nah, I have no interest in compiling Clojure to PHP.
14:02	Scriptor	though I should probably start making it more clojure-like anyway
14:02	chouser	But, making Clojure easy to extend to new target platforms, now thats interesting.
14:03	cemerick	…and probably a 5-year target
14:03	chouser	could be
14:03	gfrlog	if only clojure ran on the JVM then we could take advantage of that write-once-run-everywhere quality it has
14:03	chouser	we're certainly not as for down that path now as I was predicting at, say, Clojure Conj 2010
14:04	hiredman	I have this idea of doing functional transforms over forms (like var resolution, etc) and using something like a secd machine for code generation
14:05	hiredman	it seems nice, what little code I have
14:24	ilyak	Where is the documentation for set!?
14:24	hiredman	~special forms
14:24	clojurebot	special forms are http://clojure.org/special_forms
14:24	hiredman	possible under java interop as well
14:29	Somelauw	try (doc set!)
14:32	ilyak	(deftype TempDir [temp-dir] Closeable (close [this] (.forceDelete temp-dir)))
14:32	ilyak	What's wrong with this example?
14:32	ilyak	In practice it fails with NullPointerException on .close
14:32	chouser	what does your use of it look like?
14:33	ilyak	(.close (TempDir. (File2/createNewTmpDir "www")))
14:35	chouser	hm, looks fine to me
14:36	ilyak	Oops
14:36	ilyak	(TempDir. (File2/createNewTmpDir "www")) is NullPointerException already for some reason
14:37	ilyak	Oh nevermind, it's auto-deref I think
15:00	ilyak	It seems that ccw fails to recompile my .clj file
15:01	ilyak	therefore (deftyped class doesn't get renewed
15:01	ilyak	I wonder how would I force ccw to actually recompile everything on save
15:02	cemerick	ilyak: ccw isn't (intended to be) a build tool — though it does build projects in order to support its tooling functionality
15:03	chouser	cemerick, please tell us -- what is the build tool that we should use instead?
15:03	cemerick	chouser: oh, stop ;-)
15:06	cemerick	Screw it, I'm goin' back to ant.
15:12	pjstadig	chouser: make?
15:13	pjstadig	no, something else that starts with 'm'
15:13	pjstadig	:)
15:13	chouser	cemerick: Don't you dare! I don't know if I can use maven without you.
15:13	cemerick	bollocks :-)
15:14	ejackson	there would be a charm in naming a build system such
15:14	ilyak	cemerick: Well, it has run/console
15:14	ilyak	therefore it shoulb be able to compile whatever it takes to present a functional run/console
15:14	ilyak	should*
15:15	ilyak	I totally shouldn't call ant every time I want to run something in console
15:16	pjstadig	ejackson: just as long as its not makjure or clobuild or something
15:16	cemerick	ilyak: I was being quite sarcastic in mentioning ant, BTW
15:16	ilyak	My whole project builds using ant+ivy
15:16	ilyak	so that's what we use
15:17	technomancy	why not port ant to C?
15:17	technomancy	cant
15:17	ilyak	I even had to undust https://github.com/alamar/clojure-ant-tasks
15:18	pjstadig	technomancy: groan
15:19	ilyak	by the way, I wonder why (deftype) causes such trouble
15:19	clojurebot	deftype is see datatype
15:19	ilyak	(defrecord) surely didn't
15:19	ilyak	Maybe I misconfigured something
15:21	dnolen	so the relationship DCGs and monads becomes more interesting ... http://www.info.ucl.ac.be/~pvr/edcg.html ...
15:22	dnolen	also Prolog seems like the only lang w/ macro systems as simple as Lisp ...
15:28	pdk	defrecord still auto implements Object
15:28	pdk	deftype starts off implementing nothing
15:41	Somelauw	I remember I installed clojure-jack-in, but it looks like it is gone.
15:42	Somelauw	Since the command doesn't work anymore.
15:57	Somelauw	I'll quit again using emacs and go back to vi.
16:18	Cozey	Hello. I'm using cake and it's project.clj, but I would also like to use some of the maven functionality - like deployment to a remote directory. However, the pom.xml is overwritten by cake, and it's not possible to add a supplementary pom, except for changing a 'global' one. any tips?
16:19	carllerche	Is there a way to get leiningen to add a classpath only when running tests?
16:21	raek	carllerche: dev-dependencies won't be included in generated jars, if that helps
16:22	carllerche	I'm trying to load different property files
16:36	technomancy	carllerche: set :dev-resources-path
16:36	carllerche	technomancy: So, the problem I'm having is that I want to set different class paths for development & tests, does lein test ignore :dev-resources-path?
16:37	technomancy	carllerche: are you trying to distinguish between development and test?
16:38	carllerche	technomancy: yes
16:38	carllerche	technomancy: I would like to get different property files in development & test
16:40	technomancy	what exactly is the difference between development and test?
16:40	carllerche	technomancy: Mostly some config stuff.
16:40	carllerche	So, I'm probably doing something wrong to be honest
16:40	technomancy	no, I mean... how do you tell the difference?
16:41	carllerche	technomancy: So, I am confused about that too :P lein test is obviously one way, but running tests through swank won't be able to tell
16:41	technomancy	yes, exactly what I'm getting at
16:41	carllerche	technomancy: So, what is confusing me is that it seems that clojure.contrib.logging needs a property file to get configured
16:48	hugod	anyone been able to use tools.logging with slf4j when commons-logging is on the classpath (because a dependency uses it)?
16:49	technomancy	carllerche: if you're trying to silence logs during tests, I recommend using a fixture and twiddling the level through the log4j api
16:49	technomancy	if you're using log4j
16:51	hugod	the problem being that tools.logging uses commons-logging, rather than slf4j…
16:57	ordnungswidrig	has anybody already implemented a delegating wrapper for protocols? E.g. I have a instance x which implemenets some protocols Ps. Now I like to reify a new instance x' which implements Ps by delegating to x and which reifiy an addition protocol P2 by delegating the methods defined in P2 to another instance x2
16:58	chouser	you don't want to just extend x to P2?
16:59	amalloy	ordnungswidrig: i actually did that for deftypes and reifys this weekend
16:59	amalloy	might be parts salvageable for protocols?
16:59	amalloy	https://github.com/amalloy/ordered/blob/develop/src/deftype/delegate.clj and https://github.com/amalloy/ordered/blob/develop/src/ordered/map.clj, but likely to move around as i pull the delegating stuff into a more-general library
17:02	ordnungswidrig	amalloy: nice. it basically the same implementation I have found.
17:03	amalloy	ordnungswidrig: "found"? is this out there already? i guess i wouldn't be surprised; i was doing all this without an internet connection
17:03	ordnungswidrig	amalloy: I found it out.
17:04	ordnungswidrig	howerver I do not specifiy the protocol methods but extract if from the protocol
17:06	Somelauw	what datatype do you recommend for a chessboard? I was considering to use a vector of vectors myself.
17:06	ordnungswidrig	Somelauw: no a bad choice
17:06	Somelauw	why bad?
17:07	ordnungswidrig	Somelauw: oh, sorry. I meant "not a bad choice" :-)
17:07	amalloy	i think a T got dropped in NOT
17:07	Somelauw	either a 't' or a ',' got dropped :P
17:07	ordnungswidrig	depending on your problem domain zippers can help for easy navigation
17:07	ordnungswidrig	s/no/&t/
17:07	ordnungswidrig	g
17:08	ordnungswidrig	amalloy: to bad that in my case the delegate will return a new instance for every method invocation that leads to a newly reify delegator instance...
17:09	ordnungswidrig	I suppose reify is costly.
17:09	amalloy	ordnungswidrig: no, reify should be pretty cheap
17:09	amalloy	just a constructor call, with one argument for each local you close over
17:09	ordnungswidrig	amalloy: doesn't it generate a new java class?
17:09	amalloy	no
17:09	Somelauw	ordnungswidrig: okay, thanks
17:09	amalloy	the compilation all happens when you load the file
17:11	amalloy	(let [f (fn [n] (reify IDeref (deref [this] n)))] (map f (range 5))) ;; compiles the reify once, calls its constructor five times, with a different arg each time
17:12	amalloy	&(map class (let [f (fn [n] (reify clojure.lang.IDeref (deref [this] n)))] (map f (range 5))))
17:12	sexpbot	⟹ (sandbox10562$eval12633$f$reify__12635 sandbox10562$eval12633$f$reify__12635 sandbox10562$eval12633$f$reify__12635 sandbox10562$eval12633$f$reify__12635 sandbox10562$eval12633$f$reify__12635)
17:12	amalloy	ordnungswidrig: as you can see they all have the exact same class
17:13	ordnungswidrig	amalloy: I have a different case here: a macro which evaluates to a reify call where the protocol implementation functions will call the macro itself at runtime.
17:13	amalloy	uh
17:13	ordnungswidrig	maybe I'm a little too meta here.
17:13	amalloy	you're eval'ing at runtime? then yeah, everything will be expensive
17:14	ordnungswidrig	not a literal eval but a reify at runtime
17:14	amalloy	ordnungswidrig: i think you're confused. my example above did five reifies, at runtime, and only compiled anything once; if you're not using eval, it's hard for me to imagine how you could do otherwise
17:14	amalloy	do you have some example code?
17:17	manutter	Somelauw: you were saying your clojure-jack-in wasn't there after you installed it?
17:17	manutter	Somelauw: (sry, catching up on my scrollback here...)
17:17	amalloy	chouser: would it be wrong for me to say that it's very hard to compile something at runtime without using eval?
17:18	ordnungswidrig	https://gist.github.com/82de4ebfd6a331c029a2
17:18	Somelauw	manutter: yes
17:18	amalloy	(or, a macro that uses eval)
17:18	Somelauw	manutter: I remember having installed it.
17:18	chouser	amalloy: hm. what about 'compile'?
17:18	manutter	Somelauw: I had a similar issue -- I think it was because I installed clojure-mode.el manually instead of via packages
17:18	chouser	(doc compile)
17:18	clojurebot	"([lib]); Compiles the namespace named by the symbol lib into a set of classfiles. The source for the lib must be in a proper classpath-relative directory. The output files will go into the directory specified by compile-path, and that directory too must be in the classpath."
17:19	chouser	amalloy: I think I might agree with the gist of that statement, but maybe quibble over the word "hard" or something.
17:19	ordnungswidrig	I'm defining a function o using letfn which call reify (via another macro). This function o is used by the functions used in the reification[sic?].
17:19	manutter	Somelauw: it was an easy fix, (add-to-path 'autoload "~/.emacs.d") (require 'clojure-mode) in my .emacs file
17:19	amalloy	chuckle
17:19	Somelauw	manutter: So how should clojure-mode be installed. Using packagage-install?
17:20	manutter	Somelauw: That's off the top of my head but I think I got the syntax right
17:20	chouser	"undesirable" or something instead?
17:20	manutter	Somelauw: I had put clojure-mode.el in my ~/.emacs.d directory of course
17:20	amalloy	chouser: i guess what i meant was "hard to do accidentally"
17:21	manutter	Somelauw: yeah, I think package-install is the technically correct way to do it
17:21	Somelauw	manutter: After I did that, should I reinstall clojure-drop-in?
17:21	amalloy	ordnungswidrig: that all happens at compile-time. each call to make-dispatcher will expand into a new reify body, which will be compiled as the macro is expanded
17:21	manutter	Somelauw: Once I did that everything worked again
17:21	amalloy	you can't expand the macro "at runtime" without eval, so it will be mostly just a constructor invocation
17:21	chouser	amalloy: ah! yeah, that might be good
17:21	ordnungswidrig	amalloy: hmm, I think that's correct
17:22	manutter	Somelauw: I didn't need to do anything else (except open a new emacs)
17:22	ordnungswidrig	amalloy: but the type reported by "type" changes after every invocation of a delegated method!
17:25	Somelauw	manutter: It says: Symbol's function definition is void: add-to-path
17:25	amalloy	Somelauw: probably you want add-to-list
17:26	amalloy	usually that's like (add-to-list 'load-path "some-directory")
17:27	Somelauw	After doing add-to-list: Symbol's value as variable is void: autoload
17:27	manutter	Somelauw: Yeah, I'm not fluent in elisp yet, sorry
17:28	hiredman	Somelauw: what version of emacs are you using?
17:28	Somelauw	me neither.
17:28	Somelauw	emacs 23
17:28	manutter	Somelauw: try (add-to-list 'load-path "~/.emacs.d")
17:28	manutter	Somelauw: and if that works give amalloy the credit :)
17:29	Somelauw	It doesn't crash, but it doesn't work either.
17:30	Somelauw	But should there be a file called clojure-mode in emacs.d?
17:30	Somelauw	Since I can't find that file either.
17:30	Somelauw	Or directory
17:31	amalloy	Somelauw: you're looking for clojure-mode.el
17:31	amalloy	technomancy: sounds like Somelauw is lost, but i don't really know the details of the "distribution"-like things you do for clojure-mode
17:32	Somelauw	I think I will need to reinstall it or something.
17:32	manutter	Somelauw: yeah it sounds like the problem you're having is different than the one I was having
17:32	technomancy	it should be in ~/.emacs.d/elpa/clojure-mode-1.x.x/
17:32	amalloy	Somelauw: see, when in doubt highlight the expert's nick
17:33	manutter	Ok, you're in capable hands here, I'll take off now :)
17:33	Somelauw	okay, thanks
17:33	Somelauw	I will try a reinstall.
17:39	Somelauw	Okay, I got it to work again.
17:46	ordnungswidrig	amalloy: I solved the mystery of runtime reification: for every macro-invokation (at the repl) you'll get a different implementation, of coure.
17:46	amalloy	yep
17:48	ordnungswidrig	I'm really lost in macro-meta-space
19:54	amalloy	anyone know why there aren't (or know that there in fact is) transient versions of sorted-set and sorted-map?
20:02	TimMc	Time for me to look up how the transients are implemented.
20:05	TimMc	transient takes a c.l.IEditableCollection, conj! take ITransientCollection.
20:10	TimMc	amalloy: sorted-{map,set} are backed by PersistentTree{Map,Set}, which do not implement IEditableCollection.
20:11	amalloy	TimMc: yes, i realize that. i'm asking if there's a reason they don't implement it
20:11	TimMc	just exploring
20:15	TimMc	I'd like to know as well.
20:16	amalloy	TimMc: i suspect it's just a lot of work to write, and rich didn't think it was worth the time
20:18	scgilardi	http://groups.google.com/group/clojure/browse_thread/thread/1281d1f7bfc6c5fa has a discussion about it (from long ago)
20:18	TimMc	amalloy: My guess was that you could bang on a transient and then sort it.
20:19	amalloy	scgilardi: thanks
20:20	amalloy	TimMc: not really satisfying. say i have 2M entries in a sorted set; just calling (persistent! (transient s)) would be O(n) for pouring stuff in and out of the non-sorted version
20:20	amalloy	nlogn, really, since sorting would have to happen on the way back out
20:22	TimMc	Hmm.
20:22	TimMc	Depends on how much hammering you are doing, then.
20:23	TimMc	If you will mutate it n^2 times, it might be worth it. :-P
20:23	hiredman	obviously we should just sit around and complain about not having pods
20:24	amalloy	(inc hiredman)
20:24	sexpbot	⟹ 3
20:36	kir	hmm
20:36	kir	actually a decent number of people here
20:37	amalloy	kirroyale: no decent people though
20:37	kirroyale	well obviously
20:37	kirroyale	I'm in an irc channel
20:37	dnolen	kirroyale: ha! #clojure is one of the more civilized irc spots.
20:38	kirroyale	Then I will most likely be in shock for a while
20:38	kirroyale	I usually frequent the less civilized ones
20:38	kirroyale	However I doubt I'd get any useful answers or even any answers at all there :p
20:49	kirroyale	any decent genetic algorithm libraries written in clojure?
20:50	TimMc	How much could really be shared between multiple genetic algorithms?
20:50	TimMc	SO much is specific to the domain.
20:51	kirroyale	That's why a framework for easily defining genetic algorithm domains
20:52	TimMc	hmm
20:52	eliantor	hi everyone
20:52	TimMc	kirroyale: I suppose a framework would be useful.
20:52	kirroyale	I think so :p
20:52	clojurebot	Titim gan éirí ort.
20:52	kirroyale	And given clojure is highly extensible anyway as the whole code as data thing goes
20:53	kirroyale	seems like clojure/lisp is THE language to do it in
21:04	eliantor	is it possible to extend a protocol to a specific instance?
21:04	amalloy	eliantor: no, and i'm not sure why you would?
21:06	dnolen	eliantor: you can create a single instance that implements a protocol w/ reify though.
21:07	amalloy	dnolen: that uses the protocol's auto-generated interface rather than the protocol itself, right? not that i'm saying that's bad for eliantor, just curious
21:07	eliantor	dnolen: but it would not retain the identity... i mean like ruby singleton methods
21:08	dnolen	eliantor: what do you mean "it would not retain the identity" ?
21:08	amalloy	eliantor: no, you cannot modify an object once it is created
21:08	dnolen	kirroyale: this looks interesting, http://www.cl-user.net/asp/libs/GECO
21:09	amalloy	dnolen: (let [x 10, implementing (reify whatever (method [this] (...use x...)))] (identical? x implementing))
21:09	dnolen	kirroyale: seems like protocols would be a good way to build a performant genetic algo lib along these lines.
21:10	dnolen	amalloy: eliantor: the desired behavior is easily preserved by implemnet equals tho right?
21:10	amalloy	dnolen: the desired behavior is a little crazy
21:10	eliantor	i was tring to attach values to something, like metadata... and it seemed to me a way to solve that
21:11	dnolen	identical? use seems to me only idiomatic for perf reasons.
21:11	eliantor	but i'm just learning :)
21:11	dnolen	or subtle algorithms.
21:12	dnolen	eliantor: so you just want to make a singleton?
21:18	eliantor	dnolen: https://gist.github.com/1037018
21:18	eliantor	suppose i want to have something like that
21:18	eliantor	for a class that don't have metadata
21:19	kirroyale	I'll take a look dnolen
21:19	eliantor	is there a way to do that? i thought that having something like ruby singleton methods, would allow that
21:20	dnolen	eliantor: yeah you can't add metadata to objects you don't control, even more impossible w/ primitive types.
21:21	dnolen	eliantor: invokeDynamic or a very fancy reflection powered macro can simplify the object case, but not the primitive case.
21:24	eliantor	dnolen: well the primitive was just an example, it's anyhow impossible to do in a simple way for objects too... i guess.
21:25	dnolen	eliantor: yes no simple way. it's advantage of the Ruby/Objective-C/Smalltalk model that Clojure simply does not enjoy.
21:28	amalloy	dnolen: since you're here, i wonder if you can help me with achieving some java performance, or figuring out why i'm not
21:28	eliantor	dnolen: would it be heavy to support (performance wise) or is it a design choice?
21:29	kirroyale	really do need to learn clojure better
21:29	kirroyale	oh well
21:29	dnolen	eliantor: JVM limitation really - fundamentally early bound design. invokeDynamic is the proper solution.
21:29	kirroyale	anyway back to idle
21:30	dnolen	amalloy: what's up?
21:30	amalloy	dnolen: i'm implementing "ordered maps" that retain insertion order; my current draft is at https://github.com/amalloy/ordered/blob/feature%2Fmulti-map/src/ordered/map.clj
21:31	dnolen	eliantor: Clojure will probably get invokeDynamic support at some point but it's very JDK 7 centric, and Clojure supports JDK 5.
21:31	amalloy	i've also implemented ordered sets, layered on top of those in the same way that sets are built on top of maps in clojure.core
21:31	amalloy	when i compare my (reflection-free) implementation with the pure-java implementation ninjudd did a while ago at https://github.com/ninjudd/ordered-set/blob/master/src/jvm/clojure/lang/PersistentOrderedSet.java, his is 3-4 times as fast
21:32	dnolen	amalloy: is this using fn maps + extend-type ?
21:32	amalloy	dnolen: deftype
21:32	amalloy	(inline)
21:33	amalloy	the map in my deftype is for automatically delegating methods to an instance field
21:35	amalloy	the basic algorithm is to keep one map of keys=>[index, value] pairs, and another of index=>[key, value] pairs, so that you can do fast insertions and fast dissocs while still keeping ordering
21:35	amalloy	in practice i've split the key=>index/value map into two maps, so that i can delegate getter methods to the key=>value map directly
21:36	dnolen	amalloy: and you observe the perf difference where?
21:38	amalloy	dnolen: conj and into are my test cases: see src/bench/set.clj. my benchmarking is to call, from swank,
21:38	amalloy	(do (System/gc) (time (dotimes [n 10] (into-stress-test :m (amalloy/ordered-set))))) ; and again with ninjudd's
21:40	amalloy	for disj i beat the bejeezus out of him, because i overwrite the vector with nils instead of shrinking it
21:41	ninjudd	amalloy: you were actually beating the bejeezus out of me across the board until i suggested you change it ;)
21:41	dnolen	amalloy: can't run your code because of your utils dep I think.
21:42	amalloy	dnolen: dang, sorry, i didn't push that
21:43	amalloy	dnolen: should be on clojars now
21:43	amalloy	though i think i'm not even using the function from my utils anymore; you could delete the dependency if you want
21:44	amalloy	oh, that's a lie
21:44	ninjudd	oh. i misunderstood. i guess mine was faster. too bad. i was hoping to never write another line of Java again
21:48	dnolen	amalloy: hmm seems like lib is not on clojars yet, and you do use transform-if from yr utils.
21:49	amalloy	dnolen: hm. i pushed, so it should be there. but i'm not actually using transform-if anymore; i'll push something with no deps in a minute
21:53	amalloy	dnolen: updated version on github now, no dependency on amalloy-utils
21:54	amalloy	(additionally, clojurebot seems to think my push to clojars worked)
21:57	dnolen	amalloy: in checkout I only have bench/map.clj not bench/set.clj
21:57	amalloy	dnolen: git checkout feature/multi-map
