2:37 duck1123: Does anyone know if CDT works with 1.3? I'm able to set breakpoints and step around, but whenever I try to reval, I get an exception

6:23 LauJensen: Morning all ya'll

6:25 robonobo: mornin'

6:25 bsteuber: hi

7:57 robonobo: is there a macro for (cond (= foo bar) (...) (= baz bar) (...) ...)

7:57 ?

7:59 MayDaniel: robonobo: (case bar foo (..) baz (...)) or (condp = bar foo (...) baz (...))

7:59 robonobo: MayDaniel: thanks!

8:24 pyr: hi

8:24 when starting lein repl, should i be able to directly access my namespaces ?

9:11 odyssomay: which is best? http://pastebin.com/5DcT5zM8

9:13 cinch: pyr: yes, when you start the repl you're in the user namespace, then you can switch to another namespace with (in-ns 'my.name.space)

9:16 bsteuber: odyssomay: I'd use (reduce * (range 1 x))

9:16 ,(reduce * (range 1 3))

9:16 clojurebot: 2

9:17 bsteuber: ,(reduce * (range 1 (inc 3)))

9:17 clojurebot: 6

9:18 odyssomay: bsteuber: yes, that's alot better

9:21 More generally: is it OK to create different versions of a function wich is only used by the function itself? (as I did with fact2 in the paste above)

9:22 bsteuber: I think if it's not meant to be used from other functions, an inner function is cleaner

9:23 odyssomay: ok

9:23 bsteuber: or a private helper function

9:30 odyssomay: bsteuber: btw, using (reduce * (range 1 (inc x))) takes ~10ms with x=1000, recursively (with recur) it takes ~4ms

9:44 LauJensen: odyssomay: Like, that is just Hotspot warming up, test with Criterium

9:49 odyssomay: LauJensen: hotspot?

9:49 LauJensen: odyssomay: yes sir

9:51 odyssomay: grab this https://github.com/hugoduncan/criterium then run (bench :verbose ...) where ... is first your reducer version and second the recur version, then paste the results in here

10:17 no_mind: is there an online index for clojure symbols/operators such as ~@, ->, --> . Searching google for these is useless

10:19 opqdonut: clojuredocs.org is pretty nice

10:20 Vinzent: there is cheatsheet in pdf on clojure.org

10:21 mrBliss: no_mind: like opqdonut said: http://clojuredocs.org/quickref/Clojure%20Core

10:44 raek: how would you interleave two sequences (def a [0 1 2 3]) (def b [:a :b :c]) into (0 :a 1 :b 2 :c 3)?

10:45 I'm only interested in interleaving two sequences, where the first one might have one element more than the second one

10:45 opqdonut: ,(flatten (map vector [0 1 2 3] [:a :b :c]))

10:45 clojurebot: (0 :a 1 :b 2 :c)

10:46 raek: the 3 is missing ;-)

10:46 opqdonut: yeah

10:46 tomoj: I think this works https://gist.github.com/73c9627bb97c36bbe6e0

10:46 gotta be a nicer way to do it of course

10:46 opqdonut: of course a recursive solution is easy to write

10:51 raek: my recursive solution: https://gist.github.com/802959

10:53 tomoj: opqdonut: thanks for the input

11:22 robonobo: i tried to make a lazy interweave as well, but the lazy part doesn't seem to work. https://gist.github.com/802982 What am i doing wrong?

11:24 Chousuke: robonobo: loop is not lazy

11:25 robonobo: is there something i could use in replacement?

11:25 raek: robonobo: you should do the work inside the lazy-seq form

11:25 Chousuke: what is interweave supposed to do?

11:25 odyssomay: LauJensen: http://pastebin.com/MarSzNJs

11:25 robonobo: Chousuke: Take two collections and return a lazy seq of alternating items

11:25 from the first coll, then from the second etc until one of the

11:25 collections is runs out of elements.

11:25 raek: robonobo: yes. ordinary recursive calls, but having the code that performs the recursive call inside a lazy-seq form

11:25 Chousuke: robonobo: interleave? :P

11:26 raek: (I renamed mine "alternate")

11:26 LauJensen: odyssomay: Would be great to see the code as well

11:26 robonobo: raek: so (lazy-seq (loop [] (recur)) ?

11:27 raek: almost. do the looping by recursive calls: (defn foo [x] (lazy-seq ... (foo (rest x)) ...))

11:27 odyssomay: LauJensen: http://pastebin.com/pWNP7z7x

11:27 raek: all code inside lazy-seq will be delayed

11:28 it will be evaluated when the you call seq (or any sequence function) on the object returned by the lazy-seq form

11:28 s/when the you/when you/

11:28 sexpbot: <raek> it will be evaluated when you call seq (or any sequence function) on the object returned by the lazy-seq form

11:29 LauJensen: odyssomay: I think it may be because fact4 is working on a seq and fact3 isnt. Also internalReduce is probably doing some optimization.

11:30 tomoj: &(do (map inc (lazy-seq (println "foo") '(3))) nil)

11:30 sexpbot: ⟹ nil

11:30 LauJensen: &(time (dotimes [i 1000] (loop [acc 1 x (range 1 100)] (if (seq x) (recur (* acc (first x)) (next x))))))

11:30 sexpbot: ⟹ "Elapsed time: 122.954677 msecs" nil

11:30 LauJensen: &(time (dotimes [i 1000] (reduce * (range 1 100))))

11:30 sexpbot: ⟹ "Elapsed time: 117.813001 msecs" nil

11:33 odyssomay: LauJensen: I see

11:35 raek: robonobo: to play around with laziness, I recommend something like this: https://gist.github.com/480608

11:36 try something like (def x (ask-the-user-seq)) and try to call (first x) (take 3 x) etc

11:36 robonobo: raek: thanks, I find laziness hard to wrap my brain around. Are there any good tutorials?

11:38 raek: well, there's this one: http://clojure.blip.tv/file/734409/

11:38 but it's slightly out of date

11:39 robonobo: the example you gave is a pretty good starting point

11:39 raek: (lazy-cons has been replaced by lazy-seq, empty seq and nil is not the same thing anymore)

11:39 ,(doc lazy-seq)

11:39 clojurebot: "([& body]); Takes a body of expressions that returns an ISeq or nil, and yields a Seqable object that will invoke the body only the first time seq is called, and will cache the result and return it ...

11:40 pppaul: hey, i'm having problems with (ns mynamespace (:require [myfile :as :mycode]). clojure can't find myfile.clj even though it's in the same folder as the file looking for it

11:41 raek: I think the docs for lazy-seq accurately describes how it works. though it probably does not help you with getting a feel for how lazy seqs are written

11:41 robonobo: also, check out this: http://clojure.org/lazy

11:41 pppaul: ,(#(% # (% %)))

11:41 clojurebot: No dispatch macro for:

11:42 raek: pppaul: are you using leiningen or cake?

11:42 pppaul: leiningen (but i'm outside of it now, running from emacs)

11:42 should i start up my project from leiningen

11:43 raek: why? swank-clojure + slime allows you to have both...

11:43 pppaul: i cus i think my emacs is a bit broken (swank/slime problems)

11:43 my slime is fucked

11:44 is it hard to do this without swank/slime?

11:44 raek: I find it easiest to install slime from ELPA/package.el

11:44 and then M-x slime-connect to the swank server

11:44 that you start with "lein swank" at the terminal

11:45 pppaul: so, do i start up the server via lein, and then connect in emacs?

11:45 raek: managing the classpath yourself is (IMHO) not worth it

11:45 pppaul: will this solve the problem i'm having with clojure having the wrong classpath?

11:45 raek: pppaul: yes

11:45 pppaul: booooo classpath

11:45 raek: lein is made for handling the classpath

11:45 pppaul: ok, time to fix slime

11:46 is cake easier?

11:46 raek: https://github.com/technomancy/swank-clojure

11:46 I would say it's fairy equivalent

11:46 you use it the same way

11:46 pppaul: i don't know the difference

11:47 raek: it started as a separate project. lein and cake are now very similar for basic tasks

11:47 the swank-clojure readme (see previous link) contains most that you need to use swank-clojure and slime

11:49 if you use technomancy's emacs-starter-kit, installing slime is even more simpler, since you have package.el from the beginning

11:50 pppaul: ok, i didn't do the starter kit, i'll try that too

11:50 i have problems installing slime or swank-clojure in emacs now

11:50 troubleshooting time

11:50 raek: anyway, beware that the 'swank-clojure.el' emacs file (which used to let you start a swank server by running M-x slime) is deprecated

11:51 don't install swank-clojure in emacs

11:52 technomancy's Durendal project is a good replacement for it. it uses leiningen to do its tasks, but makes it easy to call from emacs

11:55 there's two things called "swank-clojure": 1) the clojure library swank-clojure and 2) the deprecated emacs file "swank-clojure.el", which was used for starting 1)

12:20 no_mind: how do I include a clojure lib for use in repl /

12:22 markskilbeck: no_mind: http://clojure.org/libs

12:22 tomoj: how do you get at a public field with the same name as a public nullary method?

12:23 need to read it I mean

12:23 raek: tomoj: does Foo/bar for the field and (Foo/bar) for the nullary method work?

12:24 tomoj: instance fields and methods, I should've said

12:24 raek: no_mind: use a build tool like leiningen or cake

12:25 ,(.width (java.awt.Dimension. 1 2)) ; <-- instance field

12:25 clojurebot: 1

12:25 raek: ,(.getWidth (java.awt.Dimension. 1 2)) ; <-- instance field

12:25 clojurebot: 1.0

12:25 raek: s/field/method/

12:25 sexpbot: <raek> ,(.getWidth (java.awt.Dimension. 1 2)) ; <-- instance method

12:26 raek: hrm. but what happens when they have the same name?

12:26 tomoj: exactly

12:26 the method appears to be called

12:26 no_mind: markskilbeck: that doesnt solve the problem. I have downloaded congomongo in a dir and I can :use it in a program. My problem is, i want to use the congomongo in repl. From repl when I execute (:use somnium.congomongo), I get an error java.lang.ClassNotFoundException: somnium.congomongo (NO_SOURCE_FILE:1)

12:26 tomoj: haven't found a way to get the value of the fields

12:27 raek: tomoj: maybe you can use the . form directly... don't know if that would fix the problem though...

12:27 tomoj: (. d width) didn't

12:28 raek: no_mind: that means that you didn't start the repl with that jar on the classpath. leiningen handles that stuff automatically

12:28 no_mind: raek: I specified the classpath with -cp

12:29 raek: no_mind: did you list the jar in the classpath, or the directory containing it?

12:29 tomoj: "...the name of the field is the name of the symbol, and the value of the expression is the value of the field, unless there is a no argument public method of the same name, in which case it resolves to a call to the method."

12:30 raek: (also note that if you use the -jar option, -cp is silently ignored)

12:30 no_mind: raek: I used this java -cp "lib/*" -jar lib/clojure-1.1.0.jar

12:31 raek: so how do I get congomongo in repl ?

12:31 raek: java -cp "lib/*" clojure.main

12:32 the -jar option causes -cp to be ignored

12:32 clojure.main is the main class of clojure.jar

12:33 tomoj: wall-hack-field appears to work :(

12:33 no_mind: raek: same error while :use-ing congomongo with your method

12:34 raek: no_mind: do you run (use 'somnium.congomongo) or (:use somnium.congomongo) at the repl?

12:34 no_mind: (:use somnium.congomongo)

12:42 raek: no_mind: you must use the (use 'somnium.congomongo) form at the repl. the other one is for use inside the ns macro

12:42 you got the error because you accidentally tried to look up the :use key in the somnium.congomongo java class, which does not exist.

14:34 zvrba: hmm, is there a way to write just StreamTokenizer instead of java.io.StreamTokenizer ?

14:35 Chousuke: import it.

14:45 zvrba: how?

14:45 clojurebot: with style and grace

14:46 raek: in the ns form: (ns your.namespace (:import java.io.StreamTokenizer)), when playing in the repl: (import 'java.io.StreamTokenizer)

14:48 ...either one, preferably, with style and grace ;-)

14:49 zvrba: thanks :)

15:05 brehaut: morning everyone

15:06 morning __name__

15:06 __name__: hello brehaut

15:06 brehaut: it's 9 pm over here :D

15:06 brehaut: clojurebot: UGT

15:06 clojurebot: ugt is Universal Greeting Time: http://www.total-knowledge.com/~ilya/mips/ugt.html

15:07 * __name__ grins

15:48 svdberg: hi!

15:48 __name__: hi!

15:48 xkb: what's the idiomatic way of creating lists?

15:49 brehaut: xkb: literals or programmatically?

15:49 xkb: '(1 2 3) or (list 1 2 3)

15:49 like that

15:49 like in for example a test

15:49 brehaut: i think the former is prefered

15:49 Chousuke: the former only works with literals

15:50 but most of the time you'd use lists in other lisps, you will use a vector in clojure

15:51 xkb: I ran into the problem defining the expected result of a function on seq's in a test

15:51 like (is (= expected_result (function)))

15:52 where function returns something like (1 2 3)

15:52 how would you define expected_result?

15:52 Chousuke: if it only has literals, '(1 2 3)

15:52 brehaut: xkb: as long as both expected_result and (function)'s return are both seq's (rather than maps or sets)

15:52 they should be comparable

15:52 ,(= '(1 2 3) [1 2 3])

15:52 clojurebot: true

15:53 xkb: ok, that's how I defined expected_result now

15:53 brehaut: regardless of the implementation type

15:53 xkb: in for example the empty seq case: (is (= '() (function '()))

15:54 but the literals hint is good to think about

15:55 in this specific case the elements are always Strings, numbers or nil

15:56 brehaut: xkb have you actually encountered a problem or are you trying to prevent a potential problem?

15:57 xkb: brehaut: the latter

15:57 I tried to identify the error cases

15:57 like the empty seq

15:58 so rather the potential error cases

15:58 brehaut: then dont worry. as long as both sides are sequences (lists, vectors, lazy-seqs, etc) = will do the right thing

15:58 xkb: I got some comments from a friend of mine regarding the use of ' to define a list

15:58 brehaut: and keep in mind Chousukes comment about vectors being the idiomatic sequential type in clojure

15:58 xkb: that's what triggered me to ask here :)

16:00 perhaps I should define my testdata as vectors indeed. That avoids the "problem" alltogehter

16:01 and the actual test remains the same

16:01 thanks for the help. Always nice to get quick answers to these kind of questions

16:01 brehaut: no problem

16:06 fps: just following this tutorial http://riddell.us/ClojureSwankLeiningenWithEmacsOnLinux.html

16:08 when setting up the test project in project.clj, I replaced the dependencies clojure with version 1.3.0-master-SNAPSHOT, which works.

16:09 but for clojure-contrib I used "1.3.0-SNAPSHOT", which results in a maven error, where the clojure-contrib.jar could not be found...

16:11 any tips?

16:11 brehaut: fps are you just getting started with clj?

16:12 fps: yep

16:12 brehaut: then stick with 1.2

16:12 clj 1.3 is still in alpha, i dont think contrib is following closely yet

16:13 fps: ok, will try. Thanks

16:15 * raek just discovered http://scriptor.github.com/pharen/index.html

16:15 raek: the syntax looks very clojure-inspired

16:19 Dranik: hi all!

16:19 what web framework to choose for web application development on clojure?

16:20 brehaut: Dranik: there is only one 'web framework'

16:20 but there is a range of good web libraries

16:20 that work together

16:20 Dranik: brehaut, so what's the web framework?

16:20 brehaut: Dranik: everything is built ontop of 'ring'

16:20 raek: http://www.glenstampoultzis.net/blog/clojure-web-infrastructure/

16:21 Dranik: raek, thanks

16:21 brehaut: (inc raek)

16:21 sexpbot: ⟹ 4

16:21 Dranik: wow! it's really distributed...

16:23 brehaut: Dranik: common combinations to start with are Ring, (Moustache or Compojure), (Enlive or Hiccup)

16:23 Dranik: brehaut, seems like you have some practical experience?

16:23 brehaut, do you blog about that?

16:24 brehaut: Dranik: ive built my own site/blog on ring, moustache and enlive

16:24 Dranik: wow!

16:24 brehaut: and ive written an xml-rpc library. my experience is a little limited

16:24 Dranik: where is it deployed?

16:24 brehaut: http://brehaut.net

16:24 its nothing fancy

16:24 Dranik: brehaut, oh, looks great!

16:24 really!

16:25 brehaut: thanks :)

16:25 Dranik: brehaut, do you share the sources?

16:25 brehaut: nope sorry

16:25 Dranik: :-(

16:25 brehaut: my site is always my 'learn stuff' project, so its a horrible mess

16:26 Dranik: brehaut, actually my clojure experience is so little that everything goes

16:26 brehaut: LauJensen does have an example site or two

16:26 https://github.com/LauJensen/bestinclass.dk

16:27 Dranik: thanks!

16:27 brehaut: hes also blogged about building a social media site too http://www.bestinclass.dk/index.clj/2011/01/building-a-social-media-site.html

16:28 Dranik: https://github.com/LauJensen/bestinclass.dk -- his site looks lovely

16:29 brehaut: his code is real clean. note that it 'bakes' the site for him, rather than dynamic generation. nevertheless it should show you a good example of moustache and enlive

16:29 Dranik: bendlas, yep, thank you

16:29 fps: I am not familiar with ant, how would I build the clojure-contrib 1.2.0-SNAPSHOT?

16:29 Dranik: brehaut, and your post about monads is really interesting

16:30 brehaut: fps are you using leiningen or cake?

16:30 Dranik: brehaut, I guess I translate some to my blog. Its in russian

16:30 brehaut: Dranik: monads are not an approved method of solving problems in clojure.

16:30 fps: brehaut: leiningen

16:31 brehaut: fps dont use a snapshot then

16:31 fps: haha ok

16:31 brehaut: fps [org.clojure/clojure "1.2.0"]

16:31 [org.clojure/clojure-contrib "1.2.0"]

16:31 put those into your :dependancies in project.clj

16:31 Guest51521: brehaut: what do you mean about monads not being approved?

16:31 Dranik: brehaut, yep, I thought so. But it's interesting bcs it is not idiomatic

16:31 fps: ok. thanks brehaut

16:32 Dranik: brehaut, I've just coped creating anaphoric macross with lexical variable capturing -- it was also not idiomatic but very interesting!

16:32 brehaut: Guest51521: clojure has a bunch of more specific tools to solve 95% of the problems monads solve, and they are more idiomatic

16:33 raek: fps: the tutorial you linked to uses a bit of an unusual approach to clojure development (compiling everything from source). it seems to be the norm to use pre-compiled jar files and let the build tool (lein/cake) handle the downloading and the classpath

16:33 brehaut: Guest51521: while they exists, rhickey has commented more than once that he doesnt think they are appropriate

16:34 fps: raek: ok, will remember

16:34 brehaut: Guest51521: here is teh appropriate logs http://clojure-log.n01se.net/date/2010-02-12.html#i70

16:34 Guest51521: brehaut: i'm no functional guru but from my novice perspective, they seem like a cleaner way to handle code that throws exceptions everywhere when doing interop with java

16:34 thanks brehaut. i'll read

16:34 brehaut: Guest51521: Java exceptions arent idiomatic clojure either.

16:35 Guest51521: brehaut: but you have no choice but to deal with them for java interop. the world isn't clojure on the jvm :)

16:35 i guess that's one of the 5%

16:36 brehaut: Guest51521: correct. java interop is first class, so clojure provides exception handling when you need it

16:36 but most clojure code wont throw exceptions

16:36 Guest51521: ive used monads to make error handling cleaner for some of my code, only because it makes implementing the appropriate macros simpler, especially while prototyping.

16:37 raek: brehaut: looked at that article recently. very interesting!

16:37 brehaut: However, consumers of my code dont need to know that there are monads under the hood

16:37 raek: cheers :)

16:37 raek: hopefully with the changes to the colors scheme, you can read it without loosing your eyesight too

16:38 raek: yeah, saw that that you toned down the yellow a bit

16:39 I think it's perfectly acceptable now

16:39 brehaut: raek: im a bit sad about that, but ive gotten such an overwhelm grumpy response i really couldnt not

16:40 raek: :(

16:47 Guest51521: is this a good place to ask a question about ccw in eclipse?

16:47 brehaut: Guest51521: good as any

16:48 Guest51521: i was using the stable version of teh plugin but am trying out 0.2.0.RC05 now and it doesn't give a prompt in the repl showing the namespace lke it used to. in fact there is no prompt at all in the repl, cursor is just all the way to the left. is that a bug or can i set some var to show the namespace prompt that i'm used to?

16:50 everything seems to work fine but i don't like that it doesn't display the current namespace

16:51 brehaut: i never used the repl in ccw sorry

16:55 Dranik: just done some reading on anaphoric macros; not kidding about non-idiomatic

16:56 Dranik: brehaut, sorry?

16:56 didn't get it

16:56 brehaut: You mentioned that you had recently ported anaphoric macros to clojure?

16:57 Dranik: brehaut, yep. did you read about it from Paul Graham's On LIsp?

16:57 brehaut: apparently so

16:57 Dranik: the main point there was variable capture

16:57 and that is not possible in clojure, isn't it?

16:59 brehaut: not out of the box at any rate

17:00 Dranik: that what I meant

17:00 actually, everything I had to do -- creating my own version of gensym

17:01 it looks like this

17:01 (defn make-sym [name] (. clojure.lang.Symbol (intern (str name))))

17:01 it generates unqualified predictable names for variables

17:01 brehaut: why not just (symbol (str name))

17:01 Dranik: and the rest was just translating from lisp to clojure

17:02 brehaut, guess, intern is also needed here

17:02 the function make-sym is just a simplified version of usual gensym

17:29 wjlroe: When I do (print "αβγ") from the REPL, it prints fine, but from a .clj file run from the terminal it prints "???" - why is this?

17:30 rlb: wjlroe: both from a terminal?

17:30 wjlroe: yep

17:31 rlb: wjlroe: I'd guess that clojure hooks up a fancier stream to the prompt then.

17:31 mjg123: I'm having trouble using 3rd party library in the repl. Probably a real simple problem: http://pastebin.com/SzyWS89t

17:31 rlb: just a guess, though

17:32 wjlroe: mmm

17:32 rlb: wjlroe: or the stream encoding defaults are different

17:32 wjlroe: rlb: how would I find out?

17:32 rlb: i.e. utf-8 vs something-else

17:32 brehaut: mjg123: you need to wrap parents around your use

17:33 s/nts/ns/

17:33 sexpbot: <brehaut> mjg123: you need to wrap parens around your use

17:33 brehaut: eg (use 'somnium.congomongo)

17:33 mjg123: brehaut: cheers

17:33 brehaut: mjg123: no worries. you can see the repl has evaluated both expressions (eg 'use

17:34 kjeldahl: Has anybody done simple "log to stderr" type logging from running a jetty/ring webserver with handlers from repl (with join? false)? I'm having some trouble figuring where output goes, if anywhere...

17:34 brehaut: and the quoted symbol 'somnium.congomongo) and printed them on the repl

17:34 rlb: relevant? http://jkndrkn.livejournal.com/264856.html

17:35 wjlroe: rlb: I get "MacRoman" for (.getEncoding *out*) from the REPL and from the script

17:35 rlb: wjlroe: try the -D

17:35 wjlroe: rlb: okey dokey

17:35 rlb: perhaps i.e. force utf-8 (assuming that's appropriate)

17:36 mjg123: kjeldahl: stdout/stderr are usually into logfiles for jetty/tomcat/etc

17:37 brehaut: kjeldahl: my jetty in a repl just logs to is just printed the console running the repl

17:37 kjeldahl: mjg123: Ok, thanks.

17:37 brehaut: How did you set jetty up to log to the console? Is that the log4j config or something?

17:38 wjlroe: rlb: this is -Dproperty=value right? what's the property I'm setting?

17:38 brehaut: i just start it in a seperate thread

17:38 kjeldahl: (doto (Thread. #(run-jetty #'wendigo-app {:port 8000})) .start)

17:39 rlb: wjlroe: just from glancing at that web page, perhaps "java -server -Dfile.encoding=UTF-8 ..."

17:39 brehaut: kjeldahl: i wouldnt trust that approach as canonical

17:39 rlb: wjlroe: though I'm just guessing -- I haven't really investigated

17:39 wjlroe: rlb: ok, cheers

17:40 rlb: that worked

17:40 kjeldahl: brehaut: Ok, thanks. I guess it's running in a thread already, with the "run-jetty" join? false thingy. But I'll give your method a try.

17:41 brehaut: kjeldahl: i have no idea sorry. i cobbled that together ages ago. i actually need to work out a better way to run it

17:44 wjlroe: rlb: if you are a stackoverflower, feel free to add that as an answer to my question: http://stackoverflow.com/questions/4843976/unicode-clojure-unit-test-output

17:45 rlb: I'm not, but feel free to add it yourself if you like.

17:45 (if that helps)

17:45 wjlroe: rlb: ok thanks

18:19 Guest51521: brehaut: regarding my earlier question about the namespace prompt in ccw... i see now that the namespace is displayed on the tab for the repl window. i didn't notice that at first. that is sufficient so i really don't care about the prompt then.

18:19 brehaut: Guest51521: oh true, cool

18:43 mjg123: How to read an InputStream? I just want to be able to treat it as a string.

18:48 tonyl: I haven't use InputStream but have you taken a look in clojure.java.io http://clojuredocs.org/clojure_core/clojure.java.io/

18:52 mjg123: hmm they don't make this easy in Java either...

18:52 Raynes: Calling clojure.java.io/reader on an input stream will give you a buffered reader. You can't treat it as a string, but you can do stuff like .readLine on it to get a line at a time from it.

19:00 Guest51521: mjg123: you can call read-lines from duck-streams and it will return a collection of strings

19:01 mjg123: i should say a sequence of strings

19:02 mjg123: oh sorry, you didn't say a file, just an inputstream.

19:04 http://richhickey.github.com/clojure/clojure.core-api.html#clojure.core/line-seq

19:04 combined with InputStreamReader

19:09 mjg123: Yeah, it'd be nice to have something as easy as slurp, imho

19:11 Guest51521: line-seq looks pretty nice. you just have to turn the inputstream into a reader first. no biggie

19:14 mjg123: (concat (line-seq (reader *stream*)))

19:15 indeed

19:17 AWizzArd: hiredman: ping

19:18 hiredman: just saw the msg you sent a while ago. Thanks for the info about declaring vars as dynamic explicitly.

19:20 btw, anyone, why do I get warnings in Clojure 1.3 that a var is not marked as dynamic? The compiler then sets them dynamic for me, but I don't want them to be dynamic…

19:58 technomancy: AWizzArd: that will go away during the release

20:56 replaca: technomancy: did you get C-right and C-left working in tmux? That's the one part of paredit that's not working for me under tmux and I was wondering if anyone had gotten that going.

21:23 technomancy: replaca: I had to rebind those

21:23 don't want to reach that far off the home row anyway

22:33 replaca: technomancy: what bindings worked well for you?

22:33 thanks!

22:52 technomancy: replaca: I use M-)

23:24 replaca: technomancy: (sorry, coming and going tonight) sounds like a good choice, thanks
