| 00:14 | yoklov | hobbyist: evaluate "*ns*" |
| 00:14 | yoklov | or |
| 00:15 | yoklov | really the solution is just to do "(in-ns 'your.ns.here)" |
| 00:17 | hobbyist | yoklov: It's my first less of clojure |
| 00:17 | yoklov | that's okay |
| 00:17 | yoklov | at the top of your file is there a "(ns foo.bar)" or something? |
| 00:18 | hobbyist | (ns edu.clojure.HelperClojure ;(:gen-class :as HelperClojure)) |
| 00:19 | hobbyist | I tried to add the root source file path to the repl startup with -i; no avail |
| 00:19 | yoklov | okay then in your repl try "(in-ns 'edu.clojure.HelperClojure)" |
| 00:21 | hobbyist | Perfect. I was not prefixing the \' to the FQN |
| 00:21 | hobbyist | The file runs first time when loaded in repl. Surprisingly the namespace does not persist |
| 00:22 | hobbyist | yoklov: thanks |
| 00:25 | logaan1 | in clojure for lisp programmers part one. at about 59 minutes rich hickey mentions a picture was made of the heirachy of abstractions in clojure. does anyone here know where i could find that picture? |
| 00:37 | arohner | logaan1: https://github.com/Chouser/clojure-classes/blob/master/graph-w-legend.png |
| 00:39 | logaan1 | thanks dude |
| 00:59 | devn | hobbyist: not trying to nitpick but: HelperClojure => helper-clojure |
| 01:06 | yoklov | hobbyist: you probably also don't want the gen-class. |
| 01:06 | yoklov | unless you're sure you need it. |
| 01:07 | hobbyist | I used :gen to see if it helped wit the classpath; in-ns did it. |
| 01:08 | hobbyist | helper-class is nitpick; capital offense. No more clojure. |
| 01:09 | hobbyist | tonight |
| 01:12 | hobbyist | what is the difference between "require" and "in-ns"? |
| 01:13 | laurus | How do I uninstall Clojure 1.2 version from Maven? |
| 01:15 | yoklov | hobbyist: in-ns changes your namespace, require loads libraries (namespace does not change) |
| 01:57 | doctor88 | hi |
| 01:59 | doctor88 | hi |
| 03:17 | jhickner | Is it bad form to do things like this? https://gist.github.com/2326125 |
| 03:18 | jhickner | the lock is for an object being manipulated by multiple people over websockets |
| 03:18 | jhickner | a clojurescript project |
| 03:22 | jhickner | I like just needing to import one function instead of all 3 |
| 03:53 | amalloy | well, that approach is very scheme-y |
| 03:55 | amalloy | jhickner: the closure approach is very scheme-y, and probably wouldn't be popular with clojure programmers |
| 03:55 | amalloy | perhaps more importantly, your set! looks weird/broken |
| 03:57 | amalloy | if you really loved closures, it would be acceptable to pick the second form; doing so because you don't like importing multiple functions seems like a silly reason. if that bugs you, you can do something like (:require [my.api :as lock]) (lock/owns? some-lock some-id) |
| 03:59 | amalloy | (i'll amend that to "if you really loved message-passing") |
| 03:59 | amalloy | (because, really, everyone loves closures) |
| 04:09 | jhickner | thanks amalloy |
| 04:11 | jhickner | there's just something about encapsulating everything in one nice package. but thats probably just my OO sensibilities. |
| 04:24 | dleja | Hey, if someone wouldn't mind helping me, I can't find this on google... How do i add a java library path in swank clojure mode (for emacs)? i can access the library through the lein repl after i added $LD_LIBRARY_PATH to the bash environment, but the swank server still can't find the library. What's equivalent procedure for adding the library path to swank? |
| 05:23 | Cr8 | anyone using vimclojure or nailgun with lein2? |
| 06:38 | fmn | Will jetty / ring use one thread per connection? I want to expose an expensive operation over http. |
| 06:38 | clojurebot | I don't understand. |
| 07:40 | Raynes | I just edited an AppleScript file. Someone kill me. |
| 08:36 | andyfingerhut | Anyone know off-hand of any already-implemented way to print a collection up to a maximum depth and maximum number of elements? I'm guessing clojure.pprint/pprint can do it with the proper variable settings, but not sure which ones yet. |
| 08:37 | mega` | theres a *print-length* |
| 08:38 | andyfingerhut | I'll test that with my local REPL rather than clojurebot :) |
| 08:38 | samaaron | Raynes: consider yourself spared - death isn't something you should be encouraging so readily |
| 08:39 | Raynes | samaaron: But man, it's applescript. |
| 08:39 | samaaron | Raynes: But man, it's DEATH |
| 08:39 | Raynes | You do know I was joking, right? Surely. |
| 08:39 | samaaron | haha |
| 08:39 | samaaron | of course i do |
| 08:39 | Raynes | :p |
| 08:39 | mega` | Raynes: i want to hear about your pains :D |
| 08:40 | mega` | Raynes: you need to program in applescript? |
| 08:40 | samaaron | Raynes: you should be hacking Quil for the ART-WIN instead |
| 08:40 | Raynes | mega`: I was mostly exaggerating. I deleted a few lines so that my /np IRC client command doesn't print such long now playing messages. |
| 08:41 | Raynes | /inp |
| 08:41 | Raynes | <3 |
| 08:44 | oakwise | samaaron: did you ever figure out that chrome thing? |
| 08:45 | hcumberdale | hi there! Is there a better way to write this: (map #(if (= "Welcome" (:name %1)) (assoc %1 :selected true) %1) (find-maps "categories")) |
| 08:45 | Raynes | TIL samaaron is Dr. Sam Aaron. |
| 08:46 | andyfingerhut | Ah, *print-length* and *print-level* are my friends. |
| 08:46 | andyfingerhut | Taking over the world, one bit of functionality at a time. |
| 08:47 | mega` | andyfingerhut: you know your suposed to use them with (binding ..) right? |
| 08:47 | andyfingerhut | yep. Thanks for the heads up, though. |
| 08:48 | Raynes | andyfingerhut is a lean mean (binding machine). |
| 08:48 | mega` | im going to pretend i dident smile abit from that :P |
| 08:49 | andyfingerhut | Lately I've been fired up adding little enhancements to Frank Siebenlist's clj-ns-browser. It's always impressive what can be done in not many lines of Clojure. |
| 08:51 | mega` | hcumberdale: you can write this (for [m (find-maps)] |
| 08:51 | mega` | (if (= (:name m) "Welcome") |
| 08:51 | mega` | (assoc m :selected true) |
| 08:51 | mega` | m)) |
| 08:51 | mega` | hcumberdale: not shorter but nicer |
| 08:52 | hcumberdale | thx mega` |
| 09:44 | jondot1 | hi all, what is the common construct to use, when I want the last thing in my func to run but that the func's return value won't be that thing |
| 09:45 | jondot1 | specifically, i'd like to delete a file when i'm done calculations in the function, at the end. however i want to return the calculation result and not file deletion status |
| 09:47 | mega` | the last expression in the function is returned |
| 09:47 | mega` | use let if you need to do the calculation before the file thing |
| 09:49 | mega` | (let [calc-result (calculation)] (file-thing calc-result) calc-result) |
| 09:49 | jondot1 | ah. i see. is there a 'with-' construct? |
| 09:50 | mega` | with-file? |
| 09:50 | jondot1 | that deletes a file at the end? |
| 09:50 | mega` | http://clojure.github.com/clojure/clojure.core-api.html#clojure.core/with-open |
| 09:51 | jondot1 | i see, thanks |
| 09:58 | AimHere | From the repl, '(apropos with)' might have clued you in as to all the with-foo commands |
| 10:35 | jondot1 | so, it is acceptable to call a 'heavy' function in a letrec body? |
| 10:36 | jondot1 | sorry, in a let body |
| 10:36 | jondot1 | that is (let [my-result (heavy-stuff ...params)] |
| 10:41 | progo | I do it all the time. |
| 10:41 | progo | perhaps using -> would be more idiomatic but what the heck. |
| 10:51 | devn | AimHere: only if you have ' |
| 10:51 | devn | AimHere: (use 'clojure.repl) |
| 10:56 | gavilancomun | #overtone |
| 10:59 | gavilancomun | Hi, I would like a function to take 2 parameters and return a vector of them. I know #(vector % %2) and #(-> [% %2]). Is there a better way please? |
| 11:01 | groovemonkey | hi guys, I'm looking to turn a list (:a1 :a2 :a3) into a hashmap where each value from the list becomes a key associated with an empty hashmap, i.e. {:a1 {} :a2 {} :a3 {}}. Anyone have a clever way to do that? |
| 11:02 | sattvik | gavilancomun: try vector |
| 11:04 | AimHere | ,(zipmap (list :a1 :a2 :a3) (repeat (hash-map)) |
| 11:04 | clojurebot | #<ExecutionException java.util.concurrent.ExecutionException: java.lang.RuntimeException: EOF while reading> |
| 11:04 | AimHere | Maybe one more bracket |
| 11:04 | AimHere | ,(zipmap (list :a1 :a2 :a3) (repeat (hash-map))) |
| 11:04 | clojurebot | {:a3 {}, :a2 {}, :a1 {}} |
| 11:04 | groovemonkey | awesome! Thanks AimHere. |
| 12:18 | dotemacs | Hey guys, if you're into Emacs, you might like this potential Emacs Conf: http://emacsconf.herokuapp.com/ |
| 12:36 | wysinwyg | question: I need to place a key-value pair (:streets ["street1"]) into EACH hashmap that already exists, nested a few levels down inside another hashmap {:city1 {} :city2 {}}. I've been beating my head against the wall for half an hour...how do I accomplish this? The hashmap I want to end up with is {:city1 {:streets ["street1"]} :city2 {:streets ["street1"]}} |
| 12:36 | wysinwyg | for a single one, this seems to work: |
| 12:37 | wysinwyg | (dosync (assoc-in @cities [:city1 :streets] "street1")) |
| 12:37 | wysinwyg | but for the life of me, I can't seem to get a (doseq) loop around it to apply this action to EACH :city hashmap |
| 12:38 | wysinwyg | I just get a IllegalArgumentException Don't know how to create ISeq from: clojure.lang.Symbol clojure.lang.RT.seqFrom (RT.java:487) |
| 12:49 | offby1 | Any suggestions for profiling for a newbie? I tried clojure.contrib.profile, but that seems to not work with current clojure, and I suspect I'm too green to debug it |
| 13:20 | Cyrik | hey, could someone point me to a resource on how to left-associative expressions with fnpars? |
| 13:26 | unlink | In upgrading to lein2, how do I enable lein-ring for my project? |
| 13:33 | fliebel | unlink: Enable? Is lein-ring compatible with lein2? |
| 13:33 | weavejester | fliebel: It is |
| 13:33 | fliebel | cool |
| 13:34 | unlink | it works if I install it as a user plugin, but as my project is not meaningfully useful without lein ring, I think it makes sense to put it in project.clj. |
| 13:39 | mindbender1 | when I need to specify more than one state for gen-class, how do I write that? |
| 13:40 | unlink | oh, it turns out that the problem was that I had both lein-1.7.x installed and lein 2.0.0 installed (as lein2) |
| 14:12 | mega` | dnolen: what is the type inference for? |
| 14:18 | jonasen | ,(defprotocol IMarker "Empty marker protocol") |
| 14:18 | clojurebot | #<Exception java.lang.Exception: SANBOX DENIED> |
| 14:18 | jonasen | ^ works in cljs but not in clj. Is that correct? |
| 14:19 | dnolen | jonasen: yes |
| 14:20 | jonasen | dnolen: Is there a reason for that? |
| 14:20 | dnolen | mega`: CLJS takes a huge performance hit from truth testing, it's my current mission to eliminate them wherever possible. |
| 14:20 | dnolen | jonasen: not that I'm aware of, I recall seeing a CLJ ticket for it. |
| 14:21 | Vinzent | Hi. I have a macros which expands to another macros, and in the second macro I want to have access to the var which is dynamically rebound in the first macro (in compile time). Is it clear enough, heh? :) The thing is, expansion of the second macro happens outside of scope of binding. What's the right way do to this? Currently I'm just altering-var-root in the first macro (would it be clearer to take an atom?) |
| 14:22 | dnolen | mega`: I've already succeeded at eliminating just about all of them from PersistentVector |
| 14:24 | mega` | dnolen: so you remove the truth test when theres a (= ..) case and things like that? |
| 14:25 | Vinzent | ok, I think I'd just leave things as they are now... |
| 14:26 | mega` | Vinzent: post a gist or something |
| 14:27 | mega` | Vinzent: i dont realy get the problem... you shuld probebly not use global state with macros |
| 14:27 | mega` | Vinzent: what is it you are doing? |
| 14:29 | unlink | getting this NPE from lein ring war: http://dpaste.com/728236/ |
| 14:30 | dnolen | mega`: yes, for all boolean predicates, but that's not enough for common tests |
| 14:30 | Vinzent | um, is cljbin down? |
| 14:31 | dnolen | mega`: so I added simple type inference for the if test expressions |
| 14:31 | Vinzent | mega`, https://refheap.com/paste/1905 |
| 14:32 | mega` | Vinzent: you can put meta data on the symbols |
| 14:32 | Raynes | Awww, refheap was your second choice? :p |
| 14:33 | Raynes | But no, cljbin is not down. |
| 14:33 | Raynes | I lose a chest hair every time you render the page though. Keep it in mind. |
| 14:34 | Vinzent | mega`, I'm not sure how this'd help in this case, can you explain? |
| 14:34 | mega` | Vinzent: and the binding will not work .. the stack unroles when the macro returns but i ges you know that |
| 14:35 | y3di | has anyone done any extensive game dev in clojure? |
| 14:35 | mega` | Vinzent: whell in this example i wuld youst put the string "foo" as adition argement to foo |
| 14:35 | Vinzent | Raynes, haha, sorry! cljbin has so attractive design, I want to see its main page again and again - I just can't help it! :) |
| 14:36 | Raynes | Heh. |
| 14:36 | mega` | Vinzent: https://gist.github.com/2331195 |
| 14:36 | Raynes | I guess if you like a big white box and various shades of purple. :P |
| 14:37 | mega` | Vinzent: but i suspect that it dosent end there right? |
| 14:37 | Vinzent | mega`, yeah, the whole thing is to avoid explicit argument passing |
| 14:38 | mega` | Vinzent: why is that a requierment? |
| 14:38 | mega` | Vinzent: what is it you are trying to do? |
| 14:39 | Vinzent | mega`, the first macro expands to the other macro which is a part of public api, and the *a-var* is kinda implementation detail which I don't want to be present in api |
| 14:40 | mega` | Vinzent: what is x in the code is it something you can put metadata on? like a list or vector |
| 14:40 | Jesdisciple | I'm trying to use Clooj but the REPL won't evaluate anything... I've made a new project and Clojure itself is installed, anything else I need to do? |
| 14:40 | mega` | Vinzent: or can it be annything |
| 14:41 | Vinzent | mega`, I think it can be a strin |
| 14:41 | Vinzent | *string |
| 14:42 | Jesdisciple | never mind, fixedc |
| 14:42 | Vinzent | anyway, I think I could live with plain atom - as far as I can see it doesn't really needed to clear the var's value after macros, or to have that stack behaviour |
| 14:43 | Vinzent | mega`, thanks for support :) |
| 14:45 | sjl | If I have a plugin defined in :plugins [...] of a project.clj for Leiningen2, where does that plugin actually get downloaded to? |
| 14:47 | sjl | Basically I'm trying to fix lein-generative to work, but I can't seem to get my version in checkouts/ to be seen. |
| 14:47 | mega` | sjl: its probebly in ~/.lein somwhere |
| 14:48 | sjl | And when I just delete it entirely somehow the (broken) generative task is still being found |
| 14:48 | Raynes | Plugins are just maven artifacts. They're stored in the same place as everything else is in ~/.m2 |
| 14:49 | sjl | Raynes: Hmm, the only thing in .m2 on the classpath according to lein2 classpath is the clojure jar |
| 14:50 | mega` | ls .lein/plugins/ |
| 14:50 | mega` | clojurescript-0.0-1011.jar lein-cljsbuild-0.1.5.jar lein-clojurescript-1.1.0.jar swank-clojure-1.4.2.jar |
| 14:50 | mega` | jonase-kibit-0.0.3.jar lein-clojars-0.8.0.jar lein-noir-1.2.1.jar |
| 14:50 | Raynes | That's your project classpath. |
| 14:50 | sjl | Raynes: aha, you're right, it is there |
| 14:50 | mega` | theres stuff in .lein/pluggin |
| 14:50 | Raynes | mega`: That's for lein 1.x. |
| 14:50 | Raynes | lein2 doesn't use that. |
| 14:50 | mega` | kk |
| 14:51 | sjl | Raynes: okay, I can rm that dir in m2 but now it redownloads the artifact every time, even through I checked it out into checkouts |
| 14:52 | Raynes | I don't actually know anything about checkouts or how they work, unfortunately. |
| 14:52 | sjl | Raynes: is checkouts/ just for non-lein-plugin deps? |
| 14:52 | sjl | ah |
| 14:52 | Raynes | sjl: Probably want to ask in #leiningen or on the mailing list. |
| 14:53 | sjl | Raynes: I guess my question is really "how does one develop a leiningen plugin?" |
| 14:53 | samaaron | tell person "Raynes" activate |
| 14:54 | Raynes | samaaron: I've been awake for 24 hours. Do not applescript me. |
| 14:54 | samaaron | hahahaha |
| 14:55 | Raynes | sjl: You're wondering how to develop a leiningen plugin and test it in another project locally, right? |
| 14:55 | sjl | Raynes: in a nutshell, yeah |
| 14:55 | Raynes | sjl: What I do is just 'lein install' my plugin whenever I make a change. It is tedious, but it works. |
| 14:55 | sjl | basically "there's a bug in lein-generative, how can I quickly shave that yak and move on" |
| 14:55 | mega` | make a emacs macro |
| 14:55 | sjl | ewww |
| 14:56 | sjl | I mean, AI can use kicker, but still... :\ |
| 14:58 | sjl | oh god it works but feels so dirty: kicker -e 'lein2 install' **/*.clj |
| 14:59 | Raynes | sjl: If I *have* to test in a project separate from the plugin project, that's about the best way I know to do it. Unless, of course, checkouts actually do work the way you want and I just don't know it. |
| 14:59 | mega` | sjl: also write normal unit tests |
| 15:00 | sjl | Raynes: checkouts don't seem to work all all for plugins, unless I'm just doing something entirely wrong |
| 15:25 | dgrnbrg | technomancy: you there? |
| 15:48 | jaen | what would be the solution for parsing in clojure? |
| 15:49 | mega` | jaen: parsing what |
| 15:49 | mega` | jaen: theres regex :P |
| 15:49 | jaen | say parsing assembly |
| 15:50 | sjl | jaen: if you're familiar with parser combinators and don't mind a complete lack of docs, parsatron is pretty neat |
| 15:50 | dgrnbrg | jaen: are you parsing binary or strings? |
| 15:50 | dgrnbrg | does it have lots of structure or mostly lists? |
| 15:51 | sjl | jaen: making a 0x10c assembler in clojure? heh |
| 15:51 | dgrnbrg | Also, has anyone used lazy test? |
| 15:51 | jaen | sjl: right on the money |
| 15:51 | jaen | dgrnbrg: strings; just the usual assembly stuff |
| 15:52 | sjl | jaen: I'd be way more excited if you implemented a backend that compiled clojurescript to dcpu-16, actually |
| 15:52 | dgrnbrg | jaen: you can probably get away w/ regex |
| 15:52 | mega` | jaen: if you split the bits into parts u can use pathern matching :P |
| 15:52 | sjl | jaen: there are already a bunch of assemblers/emulators out there, but writing code for its cpu in a lisp would be fun |
| 15:52 | dnolen | CLJS truth optimizations, http://github.com/clojure/clojurescript/compare/master...optimize-truth, and CLJS protocol dispatch optimizations, http://github.com/clojure/clojurescript/compare/master...optimize-protocol-dispatch, feedback appreciated. |
| 15:53 | dnolen | sjl: would be super cool - and hard - would need to think of GC. |
| 15:53 | jaen | sjl: yeah, could be, but I don't know my way around cljs compiler source to pull that off probably |
| 15:53 | sjl | dgrnbrg: I think test.generative is the successor to lazytest, though don't quote me on that |
| 15:53 | sjl | dnolen: yep, not easy at all but the result would be pretty sweet |
| 15:54 | dgrnbrg | do you know if there's a lib that automatically reruns my tests when a file changes on disk? |
| 15:54 | yoklov | cljs seems like it might be too high-level of a compiler to be readily adaptable to something like that |
| 15:54 | jaen | heh, writing a gc inassembly would be somewhat challenging probably ; d |
| 15:55 | dnolen | jaen: I think you'd could write the gc in CLJS |
| 15:55 | dgrnbrg | dnolen: a really cool avenue that few environments do (afaik) for improving gc on constrained devices is to allocate pools for specific kinds of objects (to enable fast tracing gc b/c there's no dispatch storage overhead) and then have a meta-gc for those pools |
| 15:55 | dnolen | yoklov: I'm not so sure - but the CLJS code for that target would be heavily oriented around mutation I think. |
| 15:55 | jaen | actually I wanted to write the emulator and assembler first and then maybe some sort of simple extensible language with macros just for the kicks of it |
| 15:56 | yoklov | at the very least you'd have to be extremely conservative with the output code, as you don't have much space |
| 15:56 | jaen | also this would be my first serious program in clojure, I've dabbled in lisps and haskell before, but didn't code anything remotely big |
| 15:57 | jaen | dnolen: gc in cljs? I may be dumb, but how would you bootstrap that then? |
| 15:57 | sjl | jaen: heh, probably not a good first project then |
| 15:57 | yoklov | what is it, 128kb total? |
| 15:57 | dgrnbrg | could anyone help me debug my first library on clojars and corresponding lein plugin? I keep getting a really weird error in the lein plugin, but once it's done, everyone can have branch coverage analysis for their tests |
| 15:57 | dnolen | jaen: I'm thinking just repurpose the compiler - leave out the standard lib - create a new one oriented around assembly. |
| 15:58 | sjl | jaen: if you want something fun in clojure that's still Mojang-related you could fix whatever the last couple of Minecraft updates broken in https://github.com/sjl/clojurecraft |
| 15:58 | sjl | though I think the new world format basically means I get to rewrite that godawful chunk parsing code |
| 15:59 | jaen | sjl: challenging is good, I think; way more interesting than yet another noir blog for sure ; D |
| 15:59 | yoklov | jaen: if you get stuck, take a look at the end of the 5th chapter of SICP, which covers writing a scheme compiler to (a fake) assembly. |
| 15:59 | jaen | yeah, got printed sicp on me, remember that part |
| 16:00 | pandeiro | jaen: what's wrong with noir blogs ? ;) |
| 16:00 | ibdknox | yeah srsly. |
| 16:00 | weavejester | Does anyone know the recommended route for managing local dependencies in Lein2? |
| 16:01 | weavejester | I note there's the localrepo plugin, but I'm not sure if there's something in Lein2 that would be better. |
| 16:01 | jaen | Well, nothing much except it's webdev I for some reason do not like and having to do Rails at work didn't help ; f |
| 16:02 | dgrnbrg | If I have a string, and I am evaluating a macro in some namespace, how can I get a symbol whose namespace is the ns that the macro is called in, and whose symbol-name is the string? |
| 16:03 | pandeiro | jaen: i know, webdev (even with noir) still involves too much boilerplate... not sure there's any solution tho |
| 16:03 | yoklov | heh, my roommate has been working for about a week trying to write the processor from 0x10c in VHDL. apparently it's quite hard. |
| 16:03 | jaen | Hahaha, gotta love nerds : D |
| 16:04 | yoklov | haha yup. I guess the "multiplication happens in 2 cycles" is what makes it tough |
| 16:04 | pipeline | yoklov: go figure man with no experinece in hardware designs hardware and it sucks to implement in hardware :P |
| 16:05 | yoklov | hahaha, yeah |
| 16:05 | ibdknox | pandeiro: example? |
| 16:06 | pandeiro | ibdknox: just looking at the CRUD gen that was on the mailing list... i use couchdb so it's not applicable... lotta scaffolding to set up for basic ops |
| 16:06 | pandeiro | maybe that is not automatable |
| 16:06 | pandeiro | not a criticism at all of what noir offers btw, just thinking out loud |
| 16:06 | sjl | pandeiro: you might find this interesting: http://www.screenr.com/ysd8 |
| 16:06 | pandeiro | as someone relatively new to webdev but starting to feel beginner fatigue at writing the sos all the time |
| 16:07 | mega` | dnolen: your creating a testsym https://github.com/clojure/clojurescript/compare/master...optimize-truth#L0R343 |
| 16:07 | ibdknox | pandeiro: yeah, it's something I've thought a lot about, but fundamentally I think that's just how programming is |
| 16:07 | ibdknox | I don't think that's an artifact of it being on the web |
| 16:07 | dnolen | ibdknox: on an optimization kick today, looking into fn arity dispatch optimization. |
| 16:07 | ibdknox | dnolen: oo |
| 16:08 | ibdknox | dnolen: awesome :D |
| 16:08 | ibdknox | dnolen: I created a version of the compiler that gives me column/line meta on all symbols that get read |
| 16:08 | ibdknox | now I'm trying to use that through the analyzer :) |
| 16:09 | pandeiro | ibdknox: it's probably not a problem that should be solved at the app framework level, more of a bash thing... and models are not 'generalizable' from app to app i'm finding |
| 16:09 | dnolen | ibdknox: between those two branches and this one I'm about to start I think, this works covers most of the possible low level optimizations. Moving forward, optimizations will be data structure related. |
| 16:09 | ibdknox | pandeiro: yeah, unfortunately few things are generalizable even at the view level |
| 16:09 | dnolen | ibdknox: cool, I'm assuming you're using that for something fun :) |
| 16:10 | ibdknox | dnolen: that's very exciting! |
| 16:11 | ibdknox | dnolen: I might have a real-time debugger cooler than bret's binary search demo ;) |
| 16:11 | ibdknox | pandeiro: websites are weird in that way. But in terms of models, I've never found them to be generalizable regardless of what platform you're building for. Business logic is always specific :) |
| 16:12 | ibdknox | pandeiro: unfortunately programming has its fair share of boring lol |
| 16:12 | ibdknox | pandeiro: we might be able to do better though, just gotta think about it more :D |
| 16:14 | ibdknox | pandeiro: I actually tried the generalization route btw, in a php framework once upon a time ago |
| 16:14 | ibdknox | built some cool websites with it |
| 16:14 | dnolen | ibdknox: haha cool! like a high level interactive thing? not like a stepping debugger for inspecting locals and such. |
| 16:15 | ibdknox | dnolen: type some code, see a ghosted version with all the values filled in for their variables :) |
| 16:15 | ibdknox | basically a repl on crack |
| 16:16 | pandeiro | ibdknox: yeah in my short webapp building career i've found that over-eager generalization is 100x worse down the road than having to type out boilerplaty stuff |
| 16:16 | ibdknox | definitely |
| 16:17 | ibdknox | things like defremote are nice though |
| 16:17 | ibdknox | they help make organization seem more natural and less boiler-platey |
| 16:18 | pandeiro | yeah, part of it is definitely psychological... i am not the most anal organization type but i have been trained to think something's wrong if i am typing the same shit over and over |
| 16:18 | pandeiro | i am wondering right now if porting that CRUD generator to a couchdb version is a worthwhile endeavor or not |
| 16:19 | ibdknox | fwiw, I'm definitely not convinced we've really figured it out |
| 16:19 | ibdknox | I think there's a better abstraction waiting out there |
| 16:19 | pandeiro | we will keep banging out apps and it will appear, hopefully :) |
| 16:20 | pandeiro | i also wonder if there is such a thing as 'backend-agnostic', in this context... my initial intuition is no |
| 16:21 | ibdknox | in the context of crud? |
| 16:21 | pandeiro | yeah, basic database-centric webapps |
| 16:21 | ibdknox | only if someone created the magical set of über semantics |
| 16:21 | pandeiro | right |
| 16:21 | ibdknox | for datastore interaction |
| 16:21 | ibdknox | which is theoretically possible |
| 16:21 | ibdknox | jimduey sent me a paper on it after I built korma |
| 16:21 | ibdknox | it's a GSOC project ;) |
| 16:22 | ibdknox | no one has talked to me about that one though |
| 16:22 | pandeiro | well if you're still doing this when my 4-year-old has started coding, maybe he'll hit you up ;) |
| 16:22 | ibdknox | haha |
| 16:23 | yoklov | haha, the "abstract away data-store semantics" gsoc proposal sounded impossible |
| 16:24 | yoklov | or that you would need to be insanely smart to come up with a reasonable abstraction |
| 16:25 | ibdknox | I actually don't think it's that hard |
| 16:25 | ibdknox | to be honest |
| 16:25 | ibdknox | at least not to build the first parts of it |
| 16:25 | pandeiro | well in a very over simplified sense, isn't 'CRUD' already the abstraction? what if you could do (read db-name "by-timestamp-column") and it would just work, regardless of backend? is that impossible? |
| 16:25 | pandeiro | (assuming maybe some config specification i guess) |
| 16:26 | ibdknox | pandeiro: you'll need to create notions of uniqueness, the idea that fields exist and can be queries against, etc |
| 16:26 | ibdknox | take the user case as an example |
| 16:26 | ibdknox | select a user by name |
| 16:27 | ibdknox | hm, I guess ID's could be an implementation detail.. |
| 16:27 | pandeiro | yeah i have a tough time thinking through these things until i'm trying to implement them, i admit |
| 16:28 | yoklov | hm, i probably don't know enough about non-relational databases, i thought that abstracting both their semantics and the semantics of relational db's would… end up in one of them being favored. |
| 16:28 | ibdknox | yeah, not something I'm currently interested in tackling :) |
| 16:28 | ibdknox | yoklov: shouldn't be |
| 16:28 | pandeiro | and then there's couchdb having no adhoc querying to begin with... |
| 16:28 | ibdknox | though each backend will have tradeoffs |
| 16:29 | ibdknox | I had a simple proof of concept of korma over objects |
| 16:29 | ibdknox | which is basically the "worst" (or best, depending on how you think of it) backend |
| 16:29 | ibdknox | it provides you the least |
| 16:30 | ibdknox | but meh, maybe core.logic is the future ;) |
| 16:31 | pandeiro | what about rich hickey's new database? have you looked at it? |
| 16:31 | ibdknox | datomic |
| 16:31 | ibdknox | yeah |
| 16:31 | pipeline | database-as-a-service, isn't it |
| 16:31 | pandeiro | i'm completely ignorant but i assumed it would be pretty congruent to clojure's semantics |
| 16:31 | ibdknox | mhm |
| 16:32 | pandeiro | is it only available as a service? |
| 16:32 | ibdknox | You can run something locally |
| 16:32 | ibdknox | I don't think you can host the whole thing yourself though |
| 16:32 | ibdknox | but I didn't look into it too deeply |
| 16:33 | pandeiro | ibdknox: what are you using at the startup you work for, if i can ask? |
| 16:33 | ibdknox | I actually just left to start my own |
| 16:33 | ibdknox | but RFZ we used Clojure + postgres |
| 16:33 | ibdknox | and mongo for random things |
| 16:33 | ibdknox | at RFZ* |
| 16:33 | pandeiro | what was the thinking behind using mongo for random things? |
| 16:34 | ibdknox | fast writes, schemaless |
| 16:34 | pandeiro | easier than doing all the DDL? |
| 16:34 | pandeiro | k |
| 16:34 | ibdknox | I like mongo |
| 16:34 | ibdknox | it's nice for certain things |
| 16:34 | ibdknox | I actually really liked redis when I used it for typewire |
| 16:35 | pandeiro | why use postgres at all then? |
| 16:35 | ibdknox | because NoSQL is terrible at relational data |
| 16:35 | ibdknox | we also started with a django site |
| 16:36 | ibdknox | that used postgres |
| 16:36 | pandeiro | and some data really is relational by nature? |
| 16:36 | ibdknox | I think a fair number of things are more easily expressed relationally |
| 16:37 | pandeiro | i notice that i am witnessing that with the way i use couchdb, so much so that i am beginning to wonder why not use a relational db |
| 16:37 | weavejester | Does anyone know where Leiningen keeps its record of snapshot libs? It seems to be stuck, thinking a dependency isn't there when it is. |
| 16:37 | oskarth | this is turning into an interview; but may I ask why you left RFZ? Seems like you just recently started working there |
| 16:38 | pandeiro | oskarth: he's a worthy subject :) i'll hand it off to you |
| 16:39 | pandeiro | one thing that is awesome about clojure is the patience and generosity of the more advanced members of the community; awesome for those of us still at the bottom of the learning curve |
| 16:39 | weavejester | Ah, nevermind. Problem resovled by deleting the .m2/project directory |
| 16:39 | ibdknox | I was always hired with the knowledge that I'd want to do my own thing at some point and we left on very good terms |
| 16:39 | oskarth | I see :) |
| 16:39 | ibdknox | they're hiring! |
| 16:39 | weavejester | ibdknox: Have you set off to do your own thing, then? |
| 16:40 | ibdknox | and they're really a great team, and working on something that actually matters |
| 16:40 | weavejester | I ask because I've been considering doing the same. |
| 16:40 | ibdknox | weavejester: yessir :) |
| 16:40 | mega` | RFZ stands for? |
| 16:40 | ibdknox | ReadyForZero |
| 16:40 | ibdknox | https://www.readyforzero.com |
| 16:40 | weavejester | ibdknox: Do you have anything specific in mind to do, or is that a secret? :) |
| 16:41 | ibdknox | weavejester: working on some thinge for the medical industry :) Hopefully to help curb some of the waste happening in healthcare |
| 16:41 | ibdknox | Figured I worked on helping people out of debt, time to save some lives ;) |
| 16:42 | weavejester | ibdknox: Ah. Anything to do with the pharma industry / clinical trials by any chance? |
| 16:43 | ibdknox | weavejester: it definitely has applications there, though likely in a slightly different sense than you might be asking about. A lot of it is around teasing out best practices when it comes to medicine |
| 16:44 | ibdknox | weavejester: any sense what you'd be interested in doing? |
| 16:45 | ibdknox | a definite goal of mine this year is to get speaking again. Spreading the word about the awesome stuff you can do with clj(s) |
| 16:46 | weavejester | ibdknox: I'm currently employed by Medidata, who are one of the big players in clinical trial and drug testing software. Just in case you need a contact in that area, though it looks like you'll probably be in a slightly different area. |
| 16:46 | ibdknox | ah very interesting |
| 16:46 | weavejester | ibdknox: My goal is to actually start speaking ;) - I've yet to do a Clojure talk, but I'm putting one together for Ring. |
| 16:46 | ibdknox | awesome! |
| 16:46 | ibdknox | I did it a ton for MSFT |
| 16:47 | ibdknox | haven't as much since I've left |
| 16:47 | ibdknox | but I've got a couple things lined up for this year I think |
| 16:47 | weavejester | ibdknox: I've done quite a few internal talks, but never any external ones. |
| 16:47 | ibdknox | You've gotta make it state side so I can actually meet you. :) |
| 16:49 | weavejester | ibdknox: Are you west or east coast? |
| 16:49 | ibdknox | San Francisco these days |
| 16:50 | ibdknox | Alternatively maybe I can find an excuse to end up in the UK :D |
| 16:50 | oskarth | euroclojure.com/2012/ ! |
| 16:51 | ibdknox | unforunately the timing doesn't work out for me on that one |
| 16:51 | weavejester | ibdknox: San Francisco is one of my "to-visit" places. Maybe I'll try to make next Clojure West. |
| 16:51 | ibdknox | :) |
| 16:52 | ibdknox | or you could come to the conj |
| 16:52 | ibdknox | I'll find my way there somehow |
| 16:52 | weavejester | ibdknox: I'm going to the Euro conj |
| 16:53 | weavejester | ibdknox: Are there any US conjs left? |
| 16:53 | ibdknox | the official one should be toward the end of the year |
| 16:53 | ibdknox | http://clojure-conj.org/ |
| 16:54 | ibdknox | in NY it looks like by that picture |
| 16:54 | ibdknox | weavejester: it'd be an opportunity to speak ;) |
| 16:54 | weavejester | ibdknox: Ah, I should be able to make that one. |
| 16:55 | weavejester | You have a good point… I missed the deadline for the EuroClojure talks. |
| 16:55 | ibdknox | I'm doing a couple talks in Sweden toward the end of the year |
| 16:55 | weavejester | I was planning on doing something for the ldnclj group |
| 16:55 | weavejester | ibdknox: Any particular reason you'll be over there? Aside from the talks? |
| 16:56 | ibdknox | They asked me to come speak at Oredev: http://oredev.org/ |
| 16:56 | weavejester | Ah, awesome :) |
| 16:59 | ibdknox | alright folks, gotta run |
| 17:01 | weavejester | bye |
| 17:05 | konr | Can I easily serialize a function for later retrieval with something like `(spit "/tmp/foo" (serialize #(+ 3 %)))`? |
| 17:11 | arohner | konr: not really. anonymous fns aren't serializable |
| 17:12 | arohner | you can serialize the name of a fn, and call it later, by name |
| 17:15 | beffbernard | konr: you can also use pr-str |
| 17:15 | beffbernard | As long as your functions are pure |
| 17:16 | arohner | beffbernard: how would that work? |
| 17:16 | ibdknox | and capture no free vars :p |
| 17:16 | arohner | ,(pr-str #(+ 3 %)) |
| 17:16 | clojurebot | "#<sandbox$eval28$fn__29 sandbox$eval28$fn__29@18b41da>" |
| 17:16 | ibdknox | = a uesless function |
| 17:16 | ibdknox | ,(pr-str '#(+ 3 %)) |
| 17:16 | clojurebot | "(fn* [p1__56#] (+ 3 p1__56#))" |
| 17:16 | ibdknox | ;) |
| 17:18 | beffbernard | I've used this before.. (defn serialize-bytes [x] (binding [*print-dup* true] (let [s (pr-str x)] (.getBytes s "UTF-8")))) |
| 17:19 | ibdknox | better is to think about the problem differently |
| 17:19 | ibdknox | create a function that based on some straightforward input returns you the function you need |
| 17:19 | beffbernard | ibdknox: yeah you don't want to mess around with closures |
| 17:20 | ibdknox | generate the function at the time it's needed |
| 17:24 | technomancy | clojurebot: serializable-fn? |
| 17:24 | clojurebot | serializable-fn is a hack for preserving source of a compiled function: https://github.com/technomancy/serializable-fn |
| 17:33 | autodidakto | ,(doc pmap) |
| 17:33 | clojurebot | "([f coll] [f coll & colls]); Like map, except f is applied in parallel. Semi-lazy in that the parallel computation stays ahead of the consumption, but doesn't realize the entire result unless required. Only useful for computationally intensive functions where the time of f dominates the coordination overhead." |
| 18:03 | unlink | I'm having difficulty debugging a NullPointerException raised from within Leiningen. |
| 18:07 | unlink | How do I bootstrap and debug leiningen? e.g. http://dpaste.com/728236 |
| 18:22 | emezeske | technomancy: Should I expect "trampoline" to work with lein2 at this point? |
| 18:37 | emezeske | technomancy: Nevermind my question, my problem has something to do with the subtleties of :eval-in and :trampoline-promise (and my lack of understanding thereof). |
| 18:42 | daniel | when i try this in the repl it outputs correctly (properly escaped string): (pprint-json (:body (client/get "https://graph.facebook.com/19292868552")))]])) |
| 18:42 | daniel | sorry, few too many brackets there |
| 18:43 | daniel | but i try it in a [:code {:class "prettyprint"} here] and i get nothing (noir) |
| 18:43 | daniel | just get <code class="prettyprint"></code> |
| 18:44 | emezeske | daniel: pprint-json does not return a string, it prints it to *out* (which is usually stdout) |
| 18:45 | emezeske | daniel: Looks like you want json-str |
| 18:47 | daniel | aah, thanks |
| 18:48 | daniel | that has indeed done the trick |
| 18:48 | Bronsa | or wrap it with with-out-str |
| 18:49 | daniel | i actually want something else entirely |
| 18:50 | daniel | im trying to get it to pretty print in the browser (nice colours / indentation) |
| 18:50 | emezeske | daniel: I don't think clojure.data.json is meant for that. |
| 18:50 | daniel | i think i just want (:body (client/get .... and then format it with javascript |
| 18:53 | TimMc | Ew, is this right? If I hint the return value of a function in one namespace as ^File (with (:import (java.io File)) in ns) and then call that fn from another namespace that has no such import, there's a classname resolution error. |
| 18:53 | daniel | im not sure how to get the formatting, i've got the syntax highlighting |
| 18:53 | daniel | i thought pprint-json might get me the formatting |
| 18:55 | TimMc | Here's an example of this fail: https://gist.github.com/2332669 |
| 18:57 | Bronsa | TimMc: shouldn't the hint go before the function name? |
| 18:57 | TimMc | I think it goes on the arglist. |
| 18:59 | TimMc | Bronsa: From experimentation, look slike it can go either place. |
| 19:00 | amalloy | hinting the arglist is intended for (or at least related to) primitive typehints |
| 19:00 | Bronsa | oh, ok |
| 19:00 | TimMc | hum |
| 19:00 | amalloy | and is a newer option; hinting the name is an older method |
| 19:02 | Bronsa | http://sprunge.us/UdNV |
| 19:02 | Bronsa | am i missing something? |
| 19:03 | amalloy | i guess you're missing what i just said about primitive typehints? |
| 19:03 | Bronsa | that may be it. |
| 19:04 | amalloy | arglist typehinting uses a different mechanism entirely from :tag meta |
| 19:06 | TimMc | OK, interesting -- the problem I'm seeing only occurs with arglist hinting. |
| 19:14 | amalloy | TimMc: is it okay if i smugly note that File isn't a primitive? |
| 19:24 | Bronsa | amalloy http://clojure.org/java_interop type hinting section |
| 19:25 | Bronsa | "For function return values, the type hint can be placed before the arguments vector" and it type hints the argvector with String |
| 19:26 | Bronsa | this is not true anymore, right? |
| 19:31 | dleja | Hey, if someone wouldn't mind helping me, I can't find this on google... How do i add a java library path in swank clojure mode (for emacs)? i can access the library through the lein repl after i added $LD_LIBRARY_PATH to the bash environment, but the swank server still can't find the library. What's equivalent procedure for adding the library path to swank? bump |
| 19:38 | emezeske | Anyone know if there's a handy way to compare JAR versions from clojure? E.g. (compare-version "1.2.1-SNAPSHOT" "1.3.0") => 1 |
| 19:43 | dnolen | hmm is "lein kibit" not working for other people? |
| 19:48 | dnolen | multi-arity fns will get a lot cheaper in CLJS, http://github.com/clojure/clojurescript/compare/master...optimize-fn-arity, working now on making the optimization work all the way through to deftype protocol fn implementations. |
| 19:53 | emezeske | dnolen: That is awesome. |
| 19:57 | technomancy | dleja: set :jvm-opts ["-Djava.library.path=/whatever"] in project.clj |
| 19:58 | technomancy | emezeske: I had to roll my own version comparator, but you can steal it from leiningen.core.main |
| 20:01 | emezeske | technomancy: I ended up using org.apache.maven.artifact.versioning.DefaultArtifactVersion |
| 20:02 | technomancy | emezeske: that works as long as versions are always three-segmented |
| 20:02 | technomancy | it applies different logic for non-three-segmented version numbers |
| 20:02 | technomancy | 1.6.1.1 is lower than 1.6.1 according to DefaultArtifactVersion, for instance |
| 20:02 | technomancy | just FYI |
| 20:05 | emezeske | technomancy: argg |
| 20:10 | TimMc | amalloy: Can I smugly point out that the docs are wrong? |
| 20:10 | amalloy | welcome to clojure, TimMc :P |
| 20:10 | TimMc | yup |
| 20:11 | TimMc | Although... it works *sometimes*. |
| 21:00 | konr | What was again that function to alter just part of a structure, like the :X in {:a 3 {:b [11 22 33 {:X 4}]}}? |
| 21:01 | amalloy | update-in |
| 21:01 | konr | yes, thanks! |
| 21:01 | amalloy | &(update-in {:a 3 {:b [11 22 33 {:X 4}]}} [:a :b 3 :X] inc) |
| 21:01 | lazybot | java.lang.RuntimeException: Map literal must contain an even number of forms |
| 21:01 | amalloy | &(update-in {:a {:b [11 22 33 {:X 4}]}} [:a :b 3 :X] inc) |
| 21:01 | lazybot | ⇒ {:a {:b [11 22 33 {:X 5}]}} |
| 21:39 | muhoo | how would i get lein to include java sources in a jar? |
| 21:40 | muhoo | it includes the .clj sources by default, even though it's aot compiled. but it doesn't seem to be including the java sources. |
| 21:52 | emezeske | muhoo: Can't you just put the java sources in the :resource-path ? |
| 21:56 | muhoo | if i can have multiple resource-paths, then sure, i could add project/srcj to that |
| 21:56 | muhoo | i only get one resource-path in lein 1.7 tho |
| 21:56 | emezeske | muhoo: Ah, lein2 supports multiple |
| 21:57 | emezeske | muhoo: Might be something you can do with symlinks or some such |
| 21:58 | muhoo | ok |
| 21:59 | bbloom | do sorted-sets have any functions similar to those in redis? http://redis.io/commands#sorted_set |
| 21:59 | bbloom | i'd really like to have a sorted-set-by and then get a range of values |
| 22:00 | bbloom | i've got some hash-maps representing "events" with :timestamp keys & i'd like to efficiently slice and dice a set of events |
| 22:00 | hobbyist | clojurebot: Is there any change a brief description would accompany clojars.org posts? |
| 22:00 | clojurebot | Gabh mo leithscéal? |
| 22:07 | hobbyist | clojurebot: Sint total de acord. |
| 22:07 | clojurebot | It's greek to me. |
| 22:08 | hobbyist | clojurebot: you first: Gabh mo leithscéal? |
| 22:08 | clojurebot | It's greek to me. |
| 22:12 | gfredericks | bbloom: I expect finger trees can give you what you want |
| 22:14 | bbloom | this one: https://github.com/clojure/data.finger-tree ? |
| 22:15 | gfredericks | I guess so |
| 22:16 | gfredericks | I thought it was in the core distribution but I guess it got moved out |
| 22:16 | muhoo | gfredericks: i meant hooke, not hack |
| 22:17 | amalloy | bbloom: sorted sets have that feature |
| 22:17 | amalloy | &(doc subseq) |
| 22:17 | lazybot | ⇒ "([sc test key] [sc start-test start-key end-test end-key]); sc must be a sorted collection, test(s) one of <, <=, > or >=. Returns a seq of those entries with keys ek for which (test (.. sc comparator (compare ek key)) 0) is true" |
| 22:18 | amalloy | &(subseq (sorted-set 5 9 1 6 3 2) > 3 < 8) |
| 22:18 | lazybot | ⇒ (5 6) |
| 22:18 | gfredericks | amalloy: I learn so much from you by answering poorly |
| 22:18 | bbloom | oh! perfect! thanks! |
| 22:18 | bbloom | gfredericks: thank you too :-) |
| 22:19 | amalloy | subseq is a hidden little gem |
| 22:19 | bbloom | yeah, that's awesome |
| 22:20 | bbloom | i see the return type is KeySe1q |
| 22:20 | amalloy | see also rsubseq for going the other way |
| 22:20 | bbloom | so i assume it's lazy, so i can easily do: |
| 22:20 | amalloy | indeed, it is |
| 22:20 | bbloom | &(take 10 (subseq (sorted-set 5 7 1 2 4 4) > 3)) |
| 22:20 | lazybot | ⇒ (4 5 7) |
| 22:20 | amalloy | but it's not obvious to me why that would matter |
| 22:20 | bbloom | and expect that to be fast? :-) |
| 22:21 | bbloom | i'm gonna have a pretty large sorted set & might be reading it across the network |
| 22:21 | amalloy | the set itself isn't lazy, so... |
| 22:21 | bbloom | right, but the set is persistent |
| 22:21 | amalloy | i mean, you definitely can get a gain from the laziness of subseq in some circumstances |
| 22:24 | bbloom | so the reason i asked about laziness was b/c i plan to use only a start point on the subseq |
| 22:24 | bbloom | i don't necessarily want time0 to time1 |
| 22:24 | bbloom | i want time0 + 10 items |
| 22:25 | amalloy | right, pagination. so it does what you probably want |
| 22:25 | bbloom | but in reality, i need to filter the items further, so it might be step 1) fetch 100 items, step 2) filter them, step 3) possibly load another page |
| 22:25 | bbloom | kinda like reading from a file system in blocks |
| 22:25 | bbloom | 1 other question: is there a constant time way to get the reverse of a sorted set? |
| 22:26 | amalloy | *cough* see above |
| 22:26 | amalloy | rsubseq (and rseq) |
| 22:26 | bbloom | haha ok perfect |
| 22:26 | bbloom | thanks for your help |
| 22:26 | bbloom | clojure's core libs continue to impress :-) |
| 22:27 | amalloy | be aware that all these give you a seq back, not a set |
| 22:27 | bbloom | yup, that's what i expected |
| 22:38 | unlink | is there a shorthand for (difference #{:some :set} (set (keys {:some :map}))) ? |
| 22:40 | bbloom | unlink: other than defn? ;-) |
| 22:46 | gfredericks | unlink: (apply disj #{:some :set} (keys {:some :map})) maybe? |
| 22:50 | unlink | hmm |
| 22:50 | gfredericks | that at least avoids creating a new set just for fun |
| 22:51 | amalloy | that's not the same as what he asked for though |
| 22:51 | gfredericks | it ain't? |
| 22:51 | amalloy | i guess maybe it is. i was thinking of symmetric-difference; does difference not do that? |
| 22:52 | gfredericks | ,(doc symmetric-difference) |
| 22:52 | clojurebot | excusez-moi |
| 22:52 | amalloy | well it's not a builtin afaik |
| 22:52 | amalloy | &(clojure.set/difference #{1 2} #{2 3}) |
| 22:52 | lazybot | ⇒ #{1} |
| 22:52 | amalloy | i was thinking he wanted #{1 3} |
| 22:52 | gfredericks | ah just wikipedia'd it |
| 22:53 | gfredericks | yeah I think whenever I want sym-diff I combine diff and intersection |
| 22:53 | hobbyist | Scuze. I figured it was Irish. |
| 22:55 | hobbyist | @Greek: I don't understand, but I agree. |
| 23:23 | blakesmith | Anyone know how to enable request logging when using the ring jetty adapter? |
| 23:51 | blakesmith | Ah, figured it out. My log4j.properties was misconfigured. |
