0:10 hamza: ,(:trigger {:trigger (println "trigger")})

0:10 clojurebot: trigger

0:10 hamza: something like this?

1:07 zenoli: Needs a lambda to keep the println from being eval'd when it's read, I think.

1:07 ,((:trigger {:trigger #(println "trigger")}))

1:07 clojurebot: trigger

6:54 patrkris: have the STM implementation of clojure changed considerably since 1.0? I'm reading http://java.ociweb.com/mark/stm/article.html

6:54 *has

7:09 AWizzArd: patrkris: no big changes

7:09 patrkris: AWizzArd: Yeah, just found out I can do a git diff 1.0..1.1.0 LockingTransaction.java :)

7:29 Raynes: "<dom96> case insensitivity in a programming language is good"

7:36 AWizzArd: “Good” is a relative word and as such expresses an opinion, not an objective fact.

7:37 Raynes: In this particular situation, he was declaring that case insensitivity is a good thing.

7:37 Nothing to do with opinions.

7:37 But I can see how that could be otherwise interpreted, as you've just shown.

7:42 defn: Morning gents

7:59 Raynes: Oops. I left the black tea pyramid in the cup for nearly 20 minutes. I'm not sure if I should drink it now.

8:01 noidi: hehe

8:01 that probably depends on whether you brew it for the taste or the caffeine :)

8:02 Raynes: Well, I brew for both.

8:02 The problem is that I'm worried that if I drink this, my eyes will turn black and I'll be walking on the celing.

8:02 ceiling*

8:05 noidi: some tea you have there :)

8:08 AWizzArd: can't you mix it with some hot water?

8:08 Raynes: I suppose, but I'm not sure how much would balance this out.

8:08 I suppose drinking it wont kill me.

8:09 Besides that, it's too delicious to not drink, and half of it is already gone.

8:49 rrc7cz-hm: how do you have a defmethod which matches on multiple dispatch values? something like (defmethod x [:ul :ol])?

8:51 AWizzArd: Have your defmulti outputting those.

8:52 rrc7cz-hm: AWizzArd: that could get ugly fast with many values, but if that's the only way

8:52 somnium: rrc7cz-hm: multimethods use isa?, so you can use derive to setup relationships

8:53 rrc7cz-hm: I guess I could also make a macro which expands the defmethod into two, one for each

8:53 somnium: that's a great idea

8:54 somnium: rrc7cz-hm: our BDFL has many great ideas :)

8:56 rrc7cz-hm: lol yeah

9:01 dermatthias: anyone ever tried to call an agent update function via (send) in an agent update function? will this work?

9:07 AWizzArd: Hallo dermatthias, yes, this works.

9:07 rrc7cz-hm: somnium: how can you use derive when (namesace :ul) is nil? I tried (derive :ul ::list) but it's having a problem without the namespace. I tried qualifying ::list with my namespace, like foo.bar/::list, but that's throwing an invalid token error

9:08 AWizzArd: Mr. Hickey himself did such a thing in has „Ants” example.

9:09 dermatthias: ah, ok. thanks. planing something similar right now, an "Invasive weed optimization" algorithm. I finally have to look into that Ants example...

9:15 somnium: ,(doc derive)

9:15 clojurebot: "([tag parent] [h tag parent]); Establishes a parent/child relationship between parent and tag. Parent must be a namespace-qualified symbol or keyword and child can be either a namespace-qualified symbol or keyword or a class. h must be a hierarchy obtained from make-hierarchy, if not supplied defaults to, and modifies, the global hierarchy."

9:16 AWizzArd: dermatthias: weed? :)

9:17 somnium: ,(derive ::ul ::list)

9:17 clojurebot: nil

9:19 rrc7cz-hm: somnium: if :: signals a local keyword, then it uses the current ns? but then why doesn't the global : work?

9:19 somnium: ,(isa? (keyword (str (ns-name *ns*)) :ul ::list)

9:19 clojurebot: EOF while reading

9:20 somnium: ,(isa? (keyword (str (ns-name *ns*)) "ul") ::list)

9:20 clojurebot: true

9:21 somnium: there may be a better way to make ns-qualified keywords, but that should work in the dispatcher in any case

9:21 ,(namespace :foo)

9:21 clojurebot: nil

9:21 somnium: ,(namespace ::foo)

9:21 clojurebot: "sandbox"

9:23 dermatthias: AWizzArd: yeah, weed :) it's inspired by the distribution of weed and its seeds. everybody asks the same question here..."weed? ;)"

9:24 AWizzArd: gut :)

9:25 * somnium ponders applications of clojure in the hydroponics industry

9:30 rrc7cz-hm: why would *ns* return the correct ns of my file when I do something like (prn *ns*) at the top level, but when I put it inside my multimethod dispatch fn it returns clojure.core?

9:30 opqdonut: macro weirdness?

9:31 rrc7cz-hm: opqdonut: but wouldn't the macro expand the defmulti in my namespace?

9:32 opqdonut: hmm, it also might be that your dispatch fn is called from within clojure.core

9:32 I can't remember by which rules *ns* gets set

9:32 somnium: ah *ns* is getting rebound, you can use the name of your ns "my-ns"

9:33 opqdonut: yeah

9:33 rrc7cz-hm: somnium: yeah, I just was wondering why + it sucks to duplicate the ns

9:34 krumholt: hi is the author of penumbra in this channel?

9:35 rrc7cz-hm: but it _does_ work, and I'm quite happy about that

9:37 somnium: (def this-ns (ns-name *ns*)) works at top-level, *ns* must be getting rebound during macroexpansion

9:40 rrc7cz-hm: somnium: that works nicely

9:41 somnium: i just grab it right after the ns def and use that in the macro

10:24 vy: Why does Clojure complains that "More than one matching method found: aset" for (doseq [[i j] (keys adjs)] (aset next (int (coord-to-idx n i j)) -1)) expression?

10:27 AWizzArd: Is coord-to-idx a multimethod?

10:27 vy: (defn- coord-to-idx [n i j] (+ (* i n) j))

10:28 Chousuke: maybe you need to cast the -1 too

10:29 vy: Yup, that does the trick. Interesting. Should I submit a bug report?

10:29 Chousuke: nah.

10:29 I think it's not a bug, just a java interop gotcha

10:30 clojurebot: hmm… sounds like your out of heap space

10:30 Chousuke: sometimes you need additional type hints so that the compiler can resolve the correct method.

10:30 clojurebot: botsnack

10:30 clojurebot: thanks; that was delicious. (nom nom nom)

10:34 vy: Chousuke: But there are two alternatives for aset: One with 4 args, and one with 5 args. Why do I need a casting for -1?

10:34 wlr: clojurebot: it's "you're" not "your"!

10:34 clojurebot: The bird, bird, bird, the bird is the word.

10:35 wlr: :)

10:35 Chousuke: vy: The error is about a java method, not the function

10:42 jcromartie: boy, we sure are into this stuff to be sitting here on a Sunday morning (I'm making a lot of time-zone-related assumptions here)

11:41 vy: Is there an easier of turning a [[k0 v0] [k0 v0] ...] into a {k0 v0, k1 v1, ...} map than using (reduce #(let [[k v] %2] (assoc %1 k v)) {} [[k0 v0] [k0 v0] ...])?

11:41 jcromartie: yes

11:42 ,(into {} [[1 2] [3 4]])

11:42 clojurebot: {1 2, 3 4}

11:42 vy: jcromartie: Thanks!

12:11 Licenser: odd thing:

12:11 ,(partition 4 '(1 2 3))

12:11 clojurebot: ()

12:11 Licenser: bug or feature?

12:11 and sorry :( hi everyone!

12:13 okay feature

12:23 vy: How can I place more than one expression in a cond entry? IIRC, there should be a "do" in Clojure. Where it went?

12:24 Oops! There it is.

13:06 ,(pos? 0)

13:06 clojurebot: false

13:06 vy: Shouldn't 0 be positive?

13:08 Nevermind.

13:20 Licenser: hmm quiet tonight :)

13:21 a map that is a ref, and has ref's as keys, will a dosync on the map fail when only the key refs are modified?

13:22 noidi: a map can't be a ref, but a ref can point to a map

13:23 Licenser: that was what I mean, like (ref {1 (ref 1) 2 (ref 1)}) when I inc 1 and 2 in threads will there ever be transaction redos?

13:24 problem is I don't can think of a simple way to test it, I think it should not fail since the 'root' ref isn't changed but I'm not entirely sure

13:24 noidi: there shouldn't be

13:24 because you're not modifying the map itself

13:24 Licenser: *nods* kk

13:25 * Licenser 's benchmark is done and he figreus that this even got slower o.O 50% slower then using a single ref and risking collisions

13:26 noidi: let's call (ref 1) a, and (ref 2) b: the map's value is constantly {1 a, 2 b}, even if you modify the value a and b point to

13:27 Licenser: that is what I was hoping for :)

13:27 noidi: at least that's the way I think things work :)

13:27 Crowbar7: So, I wrote this ircbot in clojure and he threads. However what would be the best way to have a module based system that loads the modules which contain the trigger and then return what is sent to the connection?

13:27 threads on every instance of a trigger to be specific.

13:30 Licenser: noidi: so do I but I'm not sure since it still takes 50% longer then just using a single ref pointing to the map

13:35 woha good greif

13:36 non paralell: 11389msec; paralell: 28244msec

13:36 I am doing something hooribly wrong I fear

13:49 opqdonut: can leiningen be easily used to compile a mixed java-and-clojure project?

13:55 Crowbar7: Hmm The clojurebot code is pretty awesome looking

14:04 tomoj: opqdonut: http://github.com/antoniogarrote/lein-javac

14:04 haven't tried it

14:04 might help

14:10 ordnungswidrig: hi all

14:10 vy: FYI: An optimized version of Floyd-Warshall's APSP (All-Pairs-Shortest-Paths) algorithm @ http://paste.lisp.org/display/95370

14:53 Crowbar7: ,(* 1 2 3 4)

14:53 clojurebot: 24

15:02 AWizzArd: ordnungswidrig: good evening

15:08 ordnungswidrig: helau!

15:11 does anybody know of some clojure-lucene glue code? I found mailindex on github which I took as a "template"

15:24 redwyrm: ,((fn [x] (+ x 3) 2)

15:24 clojurebot: EOF while reading

15:24 redwyrm: ,((fn [x] (+ x 3)) 2)

15:24 clojurebot: 5

15:24 redwyrm: neat

15:26 Borkdude: Hello, Ive got some problems getting my classpath right in Clojure Box, somebody wants to help?

15:26 ordnungswidrig: ,(#(+ % 3) 2)

15:26 clojurebot: 5

15:26 ordnungswidrig: ,((partial + 3) 2)

15:26 clojurebot: 5

15:28 Borkdude: Hello, Ive got some problems getting my classpath right in Clojure Box, somebody wants to help?

15:29 AWizzArd: Hallo Borkdude. Can you tell a bit more?

15:30 Borkdude: Yes, I've tried both setf and add-to-list to the variable swank-clojure-classpath in my .emacs

15:31 the clj file i want to have in the classpath is on c:/temp/examples

15:31 raek: what is the recommended way of signaling errors in pre-deftype clojure? throwing an instance of an exception class written in ordinary java?

15:32 AWizzArd: Borkdude: in my .emacs file I have something like (setq swank-clojure-extra-classpaths '("/Users/ath/hg/src/" "/Users/ath/hg/build/" "/Users/ath/clojure/clojure.jar" "/Users/ath/clojure/swank-clojure/")) I have more entries, but those paths go into my CP.

15:33 Borkdude: hmm let me try

15:35 AWizzArd: wb ulfster, alles klar? :)

15:36 ulfster: yeah, everything fine. tortured myself playing soccer

15:40 Borkdude: AWizzArd: I have this in my .emacs now:

15:40 (setq swank-clojure-extra-classpaths (list "c:/temp"))

15:40 and my file, snake.clj is in c:/temp/examples/

15:41 but when I do (use 'examples.snake) it gives an error about the file not being found

15:42 AWizzArd: and what is the NS of snake.clj?

15:42 (ns examples.snake ...) ?

15:45 Borkdude: (ns examples.snake

15:45 (:import (java.awt Color Dimension)

15:45 (javax.swing JPanel JFrame Timer JOptionPane)

15:45 (java.awt.event ActionListener KeyListener))

15:45 (:use clojure.contrib.import-static

15:45 [clojure.contrib.seq-utils :only (includes?)]))

15:46 ordnungswidrig1: re

15:55 Borkdude: AWizzArd, any idea?

16:00 AWizzArd: Hmm, that looks okay

16:00 ordnungswidrig1: perhaps it's the slash? Have you tried "c:\\temp" for the classpath?

16:00 AWizzArd: Try (System/getProperty "java.class.path")

16:01 the slash should not be a problem, I do the same

16:01 Emacs and Java understand both, the slashes and backslashes

16:03 Borkdude: AWizzArd: "c:/Program Files/Clojure Box/swank-clojure/src;c:/Program Files/Clojure Box/lib/clojure-contrib.jar;c:/Program Files/Clojure Box/lib/clojure.jar"

16:04 it seems c:/temp is not there

16:08 AWizzArd: your path seems to be missing

16:10 Borkdude: yes, so clojure box is not picking up this: (setq swank-clojure-extra-classpaths (list "c:/temp"))

16:17 dabd: is there a generic way of maintaining the original collection type when applying a function that works on seqs? For example. if I call (distinct [1 2 3 1]) I get back a lazyseq but I would to get back a vector

16:23 chouser: dabd: (into (empty c) (distinct c)) ; usually works well

16:24 AWizzArd: dabd: nothing that is already prepared, but you can write a function that takes distinct and its arg, and then converts that back

16:24 chouser: one exception is lists, since (into () s) will reverse the order of s

16:33 dabd: the seq abstraction is nice but sometimes they are hard to work with. For example if I am working with a vector and conjoining elements to the end it, if I apply a seq function it will return a lazy seq and conj will start adding elements to the start.

16:36 miltondsilva: hi

16:38 when using slime... I often get Unable to resolve symbol... switching the order of the def and calls to def seem to work... but if someone could give me a explanation... and a more convenient way to fix this I would be grateful.

16:41 chouser: you must define a Var before you use it. Is that what you're talking about?

16:43 dabd: I haven't found that to be much of a problem. Vectors and lazy seqs are rather different things, and I usually I find the operations I want to apply group natrually so that conversion back and forth is relatively rare.

16:43 miltondsilva: yes... but.. I have def it...

16:44 example... (defn b [] (a)) below this (defn a[] )

16:44 it says

16:44 dabd: chouser: say you concat two vectors you need to do something like (into [] (concat v1 v2)) otherwise you will get a lazyseq which has diffrent semantics for conj

16:44 miltondsilva: Unable to resolve symbol

16:45 if I do (defn a[] ) then (defn b [] (a)) it works...

16:46 opqdonut: miltondsilva: as said, you need to define a symbol before you use it :)

16:47 miltondsilva: but... can't I get around this? isn't there some way to load the file in such a way that all things are loaded and only then is the top level expression evaluated?

16:48 opqdonut: you can use the declare form to switch the order of definitions: (declare a) (defn b [] (a)) (defn a [])

16:48 so for example for mutually recursive functions you must use that

16:48 miltondsilva: ok thanks :)

16:48 opqdonut: you see, there is no difference between definitions and other top-level expressions

16:49 i seem to recall that most other lisps throw the error only when you try to use (call in this case) a nondefined symbol

16:51 miltondsilva: ok... I was thinking the structure of the code was a bit less restrictive (like java) but it's not a big deal

16:53 (java is very restrictive I know.. but it is allowed to use things before declaring it)

16:53 again, thanks :)

16:59 chouser: dabd: or just (into v1 v2)

17:02 solussd: ,(str "welcome" "atrerus")

17:02 clojurebot: "welcomeatrerus"

17:15 atrerus: question for those using emacs/slime... how do you configure the classpath for general libs like clojure-contrib or ant?

17:15 dabd: ,(distinct #{1 2 1})

17:15 clojurebot: java.lang.UnsupportedOperationException: nth not supported on this type: PersistentHashSet

17:16 dabd: Isn't the distinct function supposed to work on collections? It returns an exception if applied to a Set

17:20 dnolen: atrerus: lein helps, managing the classpath manually is a serious pain.

17:20 atrerus: you can use 'lein swank' and then connect to a repl with the classpath set

17:21 atrerus: ok... is lein something specific to Clojure or is that a more general thing for emacs?

17:21 chouser: dabd: interesting. I think that's a bug, but I

17:21 but I'm not sure where.

17:22 dabd: I was looking at the implementation of distinct but I can't see it either

17:22 chouser: distinct relies on destructuring

17:23 atrerus: dnolen: what's a good page to read up on lein?

17:23 chouser: trying to destructure a set or map with a vector throws an exception because vector destructuring uses 'nth', and maps and sets don't support that.

17:23 dnolen: atrerus: check github

17:24 chouser: so I'm not sure, but my guess would be that distinct out to have another (or differently-placed) 'seq' call.

17:24 s/out/ought/

17:24 atrerus: dnolen: thanks! I'll look into that.

17:24 dnolen: atrerus: leiningen

17:26 dabd: chouse: but calling distinct on a set makes as much sense as calling it on an integer right?

17:26 so ,(distinct 2)

17:26 ,(distinct 2)

17:26 clojurebot: java.lang.UnsupportedOperationException: nth not supported on this type: Integer

17:26 dabd: so (distinct 2) equally fails

17:27 chouser: hm, I suppose you're right.

17:27 dabd: ditto to maps

17:28 but it would be more elegant if it returned the set as is instead of throwing an exception

17:32 chouser: hm. ditto for maps?

17:35 dabd: how do you remove distinct entries from a map if it doesn't have duplicate keys?

17:35 based on values?

17:35 that makes sense

18:14 ankou: hi, this question is somewhat slime related but since many clojuredeveloper seam to use slime... how can I manage projects? I know how to load a file but usually I want to load the main file of the project, how should I manage my project with slime?

18:21 atrerus: ankou: I just asked the same and was referred to http://github.com/technomancy/leiningen/tree/56683c38627a9fd69c968d27292444e252f9ecfd/lein-swank#readme

18:22 ankou: reading up on it now

18:22 Licenser: is there a lein dep für c.c 1.1?

18:23 atrerus: Licenser: that page I just linked says they have an RC

18:23 Licenser: heh

18:25 dnolen: atrerus: ankou: you just need to install leiningen 1.1.0. Then you run "lein self install". Then when you define your project add "lein-swank" as a :dev-dependency. then "lein deps" and "lein swank". You can then run M-x slime-connect and just use the defaults

18:25 http://github.com/swannodette/clj-nehe/blob/master/project.clj, to get an idea of what your project.clj should look like

18:25 ankou: okay I'll have a look at it. And another question, when there is an error how do I get the line number from slime? with C-C C-K it says: Unknown Location: Error: ... whereas enclojure actually gives me an exception with a concrete line number

18:26 atrerus: ankou: dunno, slime generally gives me a line number for a failed compile...

18:28 Licenser: ah 1.1.0 of cc isn't known to lein but 1.2.0

18:28 ankou: the error is as simple as (defn main [] (map 'x 'y)) (main) since I just wanted to try how slime handels errors but it says unknown location

18:28 dnolen: ankou: C-c C-l I think is what you want if you want errors with line numbers.

18:30 ankou: take that back, C-c C-k is right and that gives me line numbers.

18:31 ankou: C-c C-l gives me everything except for the line number. It looks exactly like the exception message of enclojure but without the line number(enclojure says Don't know how to create ISeq from: Symbol (defpackage.clj:2) followed by the backtrace whereas slime just misses the (file:n)

18:48 Licenser: could it be that the clojure contrib api isn't up to datE?

18:52 dnolen: Licenser: did you have a previous install of lein? Are you specifying clojure-contrib 1.1.0 in your deps?

18:52 Licenser: I sepcifue c.c 1.1.0 in my deps

18:52 but things like c.c.io are still c.c.d-c

18:53 dnolen: ah, yeah I don't know if what's up on Clojars is up to date.

18:53 Licenser: well if it says c.c 1.1.0 it should be 1.1.0 it's no snapshot or anything

18:53 miltondsilva: is it possible to access protected fields of class when using a proxy?

18:53 Licenser: if it's not 1.1.0 as in the API docs it should not be named 1.1.0 :P but get a different version number

18:56 dnolen: Licenser: you're right I can't import c.c.io, I'm using the latest versni of lein. Might want to mention this on the Leiningen ML

18:57 Licenser: hrm odd odd odd

19:20 the-kenny: What's the best way to do (f [:foo :bar] [42 23]) -> [:foo 42 :bar 23] (I don't want a map)

19:22 ah, nevermind. interleave is the function

19:53 lygaret: hey, y'all, hoping someone could help me with a problem, which I'm pretty sure is me not grokking the immutablity thing

19:53 I've got a struct (defstruct window :event_handlers), which needs to hold a list of event handlers in the :event_handlers key

19:54 my goal is to be able to do something like (on-event my_window :event_handlers (fn [e] ...)) and have that function be added to the list of handlers.

19:55 I'm just not sure how to go about doing that - I know I can't use assoc directly, unless I am going to put the new list back in the struct, but that's something else I'm not allowed to change.

20:11 mudge: wow, clojure

20:11 my programming interest raptures

20:12 and i sing and dance in functional unmutable persistent data structures

20:13 sorry, I couldn't help myself

21:17 jcromartie: mudge: nice

21:18 mudge: jcromartie: thanks

21:19 jcromartie: my code is waxing existential

21:19 (def *god* (agent nil))

21:19 It doesn't help that I'm listening to Tears for Fears at the same time.

21:19 I need a drink or something

21:20 mudge: yea

21:20 jcromartie: and of course, nil becomes the world on the first send :)

21:20 mudge: hmm?

21:21 jcromartie: oh the "world" of a game

21:21 simulation etc

21:21 mudge: oh okay

21:21 JayM: mudge: i agree. i didn't know parentheses could be so beautiful

21:22 scottbot: what's the idiomatic way to schedule a function to be executed in a background thread every n seconds?

21:23 jcromartie: scottbot: I'm working on this right now, actually

21:23 mudge: JayM: yea, i don't know what other people's big deal is about parentheses. They're curved and they balance symetrically, qualities of beauty.

21:24 jcromartie: scottbot: I'm using an agent

21:25 scottbot: basically, set up your agent, then send a fn that sleeps before sending itself

21:27 JayM: mudge: well put

21:31 scottbot: jcromartie: that's what I'm currently using, with a nil agent with send-off and Thread/sleep

21:31 jcromartie: yup

21:31 although make sure to understand the differences between send/send-off

21:31 send generally keeps the thread count down

21:32 scottbot: jcromartie: upon reflection, send is what I want

21:33 jcromartie: thanks!

21:37 kwertii: Trying to install 1.1.0 tag from source. Ant works fine, but mvn install gives "[WARNING] JAR will be empty - no content was marked for inclusion!" and then just copies a tiny 1k jar file to the maven repo. what am I missing?

21:41 jcromartie: scottbot: are you using an anonymous/let-bound fn for your periodic fuction?

21:42 I'm not sure how to do it without a named var

21:44 or the Y combinator... :-/

21:47 _mst: jcromartie: sounds a bit like you might want letfn to allow your function to refer to itself?

21:48 jcromartie: letfn yes

21:48 thanks!

21:48 another idiom question: how about a way to modify a value at a "key path" in a map?

21:48 like {:foo {:bar {:bat 5}}}

21:48 I want to make that 5 a 6

21:48 (for example)

21:50 _mst: ,(assoc-in {:foo {:bar {:bat 5}}} [:foo :bar :bat] 6)

21:50 clojurebot: {:foo {:bar {:bat 6}}}

21:50 jcromartie: ah, nice

21:50 _mst: or there's update-in if you want to provide a function to do the modification (like inc, for example)

21:50 jcromartie: that should be in the cheatsheet :)

21:50 beautiful

21:52 that cuts down on so much code

21:54 there could be an alter-in too

21:56 _mst: you can compose it all together with something like (alter myref update-in [:foo :bar :bat] inc)

21:56 kwertii: update, in case anyone was wondering: there is apparently no standard way to install a self-built Clojure jar into maven. (per http://www.mail-archive.com/clojure@googlegroups.com/msg21784.html)

21:56 jcromartie: ah yes, that works nicely

22:14 BrandonW: it definitely seems like clojure core was very well thought out

22:14 i've already encountered a couple times when i implemented something, then went back to optimize it and instead looked at clojure core more closely

22:14 and found that it has a function that does the same thing, except more efficiently and concisely

22:14 and i still haven't used clojure all that much

22:24 defn: hello

22:37 KirinDave_: Does anyone know of any projects that have taken compojure and added on for a less bare-bones experience?

22:39 qbg: Yes, I have defeated the transient vector with my (functional-like) mutable array deftype.

22:46 defn: KirinDave: Hmmm -- What do you mean by "less bare-bones"? As I've understood it Compojure was kind of beastly and was going to be split off into a couple different projects...

22:49 cemerick: ,(with-meta (agent nil) {})

22:49 clojurebot: java.lang.ClassCastException: clojure.lang.Agent cannot be cast to clojure.lang.IObj

22:49 cemerick: hrm

22:49 ,(supers clojure.lang.Agent)

22:49 clojurebot: #{clojure.lang.AReference clojure.lang.ARef clojure.lang.IDeref clojure.lang.IReference clojure.lang.IMeta java.lang.Object clojure.lang.IRef}

22:53 Crowbar7: So, I compiled the snapshots of clojure and clojure works fine, but I can't access the clojure-contrib libs at all.

22:54 It always tells me nil when I try to require.

22:54 any help?

22:54 It shows up in my classpath

22:57 dakrone: Crowbar7: nil is the proper response when you do (require 'clojure.contrib.foo)

22:58 so if you did (require 'clojure.contrib.seq-utils), the REPL will return nil

22:58 ,(require 'clojure.contrib.seq-utils)

22:58 clojurebot: nil

23:02 dakrone: and then you can reference it using the namespace

23:02 ,(clojure.contrib.seq-utils/flatten [1 2 3 [4 5]])

23:02 clojurebot: (1 2 3 4 5)

23:05 Crowbar7: ok

23:05 thankyou

23:05 defn: Anyone have any suggestions for libraries that would allow me to automate form submission/surfing etc.

23:05 dakrone: Crowbar7: you're welcome :)

23:06 Crowbar7: dakrone: I'm really new to clojure and so I'm getting my feet wet with a homebrew irc bot.

23:06 thank you for the help

23:08 dnolen: darkone: your clojure opennlp project looks pretty interesting. Can you use it extract name entities yet?

23:08 KirinDave: defn: For example, more automation on the generation of the routing table.

23:08 dnolen: dakrone: ^

23:08 KirinDave: defn: More generous facilities for decorators.

23:08 dakrone: Crowbar7: have you seen this yet? http://nakkaya.com/2010/02/10/a-simple-clojure-irc-client/

23:08 KirinDave: defn: Like right now, decorator order is kind of a pain to manage. If you write a decorator that depends on session stuff to be in place, yoi have to manage that by hand.

23:08 defn: KirinDave: ah -- sorry I don't have any suggestions for you -- the best bet I think would be to check out forks of compojure and see what you can come up with

23:08 dakrone: dnolen: you could use the proper-noun filter, but not specifically for names yet

23:09 KirinDave: defn: Today I started writing code to, at compile time, scan the contents of a module and use that to generate a routing table.

23:09 dnolen: dakrone: cool, yeah I'm interested in extracting named entities - people/organizations.

23:09 KirinDave: defn: metadata in the module specifies what should be what.

23:10 dakrone: dnolen: you could do a proper-noun filter coupled with a good dictionary file, anything that doesn't exist is probably a name

23:10 although that's a really messy way to do it

23:11 dnolen: dakrone: was curious because I've seen java opennlp examples that show names and organizations can both be identified using the write dictionaries.

23:11 write -> right

23:12 dakrone: dnolen: I've only done a tiny part of the opennlp library so far, so there's probably one I haven't looked at yet

23:37 Crowbar7: How do you put variables inside of clojures regex?

23:39 defn: ooo i know this one

23:40 Crowbar7: I can't remember the name of the function now, but for some reason I remember it being in str-utils

23:40 Crowbar7: ok

23:40 defn: it let's you compose a regex of several different pieces

23:40 so one of them could be a variable

23:40 Crowbar7: that will make html parsing easier

23:41 defn: you know about enlive?

23:41 Crowbar7: no

23:41 defn: look it up

23:41 it might be what you're looking for

23:43 Crowbar7: So, clojurebot is pretty cool

23:43 defn: yeah, it's a neat project to play with

23:47 Crowbar7: Who wrote him?

23:47 defn: hiredman i believe

23:47 dakrone: yea, http://github.com/hiredman/clojurebot

23:47 KirinDave: Crowbar7: Enlive is pretty damn awesome.

23:51 Did clojure.contrib.def get dropped in contrib 1.1.0?

23:56 atrerus: if I want lein to compile my clojure code into the repl, do I have to specify something in the project file?

23:56 defn: atrerus: which version of leiningen

23:56 err oh, in the REPL

23:57 atrerus: defn: 1.1... just grabbed from git today

23:57 defn: i use swank-clojure

23:57 atrerus: right

23:57 sorry that's what I mean

23:57 I fire off "lein swank" then M-x slime-connect

23:58 but I'm expecting the clj files in my src directory to be loaded...

23:58 defn: why not use M-x swank-clojure-project?

23:59 atrerus: would that give me the option to connect to the existing swank server?

23:59 defn: it spawns a new swank server with your dependencies and such on the classpath and the connects to it

23:59 then*

23:59 atrerus: ah... so no need to start the swank server via the command line
