| 00:00 | TimMc | Scroll to the bottom for the finished product. |
| 00:02 | technomancy | callen: sounds like clojurebot needs a new factoid |
| 00:16 | TimMc | clojurebot: rest is also easy to write without alphanumerics: https://www.refheap.com/paste/5980 |
| 00:16 | clojurebot | Alles klar |
| 00:20 | TimMc | gfredericks: ##(#({} %& :constant) :whatever) is my new favorite #'constantly |
| 00:20 | lazybot | ⇒ :constant |
| 00:22 | technomancy | fewer chars! |
| 01:31 | hyPiRion | TimMc: Madman. |
| 01:31 | hyPiRion | Well, it's not that long though. |
| 01:59 | john2x | how do I turn (map str seq) to use `->` syntax? (-> seq (map str)) is wrong.. |
| 02:00 | ivan | ,(-> seq (map str)) |
| 02:00 | clojurebot | #<ExecutionException java.util.concurrent.ExecutionException: java.lang.IllegalArgumentException: Don't know how to create ISeq from: clojure.core$str> |
| 02:00 | ivan | ,(->> seq (map str)) |
| 02:00 | clojurebot | #<ExecutionException java.util.concurrent.ExecutionException: java.lang.IllegalArgumentException: Don't know how to create ISeq from: clojure.core$seq> |
| 02:01 | ivan | ,(->> '(1 2 3) (map str)) |
| 02:01 | clojurebot | ("1" "2" "3") |
| 02:04 | antares_ | john2x: -> places values as the first argument. You need ->> (places arguments to the end) |
| 02:04 | antares_ | john2x: I doubt (map str seq) really needs to use ->>, though, it is best readable as is |
| 02:05 | john2x | antares_: thanks. yeah, i guess I'll do my chaining elsewhere |
| 02:27 | shriphani | hello clojure-devs. I am starting learning clojure and I can't debug why this 1 line example doesn't work: user=> (defrecord Book [title author]) |
| 02:27 | shriphani | java.lang.Exception: Unable to resolve symbol: defrecord in this context (NO_SOURCE_FILE:43) |
| 02:29 | noidi | what version of clojure are you using? |
| 02:29 | shriphani | how do i check ? |
| 02:29 | shriphani | Clojure 1.1.0 |
| 02:29 | shriphani | too old ? |
| 02:29 | noidi | okay, that's *ancient* :) |
| 02:30 | noidi | it's from time before records and protocols |
| 02:30 | shriphani | oh wow. |
| 02:30 | noidi | I suggest you start by downloading leiningen (it's a bit like Maven for Clojure, but not nearly as scary) https://github.com/technomancy/leiningen |
| 02:31 | noidi | (or Rubygems or PIP or whatever) |
| 02:31 | shriphani | i just got clojure off brew (I'm on os x). |
| 02:32 | shriphani | and i can defrecord now. |
| 02:32 | noidi | ok, cool :) |
| 02:33 | john2x | how do I convert a string to a regex? something like (str #"" "blah" "$") => #"blah$" |
| 02:33 | noidi | in any case you should check Leiningen out. it's the de facto way to manage the clojure version and dependencies that your project is using |
| 02:34 | noidi | john2x, http://clojuredocs.org/clojure_core/clojure.core/re-pattern |
| 02:34 | john2x | noidi: oh missed that. thanks |
| 02:50 | john2x | is there a way to reload all libs loaded in the current REPL? |
| 02:52 | Iceland_jack | a |
| 02:53 | arrdem | is there a good way to build one value between several macro invocations? |
| 02:54 | arrdem | I'm wishing for a way to write a macro wich will expand into a (def), and also insert an entry into a map. |
| 03:00 | ChongLi | arrdem: yeah, wrap it in a do block |
| 03:00 | ChongLi | errr, I misread |
| 03:04 | noidi | john2x, I haven't tried it, but clojure.tools.namespace seems to do that https://github.com/clojure/tools.namespace |
| 03:04 | noidi | apparently all you need is (use '[clojure.tools.namespace.repl :only (refresh)]) (refresh) |
| 03:09 | john2x | cool. thanks. hmm I get "Could not locate clojure/tools/namespace/repl". that means I have to add it in my project.clj? Is there a way to always use it for all my REPL's in the future? I'm using leiningen 2. |
| 03:16 | noidi | john2x, check out leiningen's profiles https://github.com/technomancy/leiningen/blob/master/doc/PROFILES.md |
| 03:17 | noidi | add a :user profile in ~/.lein/profiles.clj which adds tools.namespace as a dependency |
| 03:18 | noidi | and it'll be available in all your projects |
| 03:20 | abp | john2x: are you converting user input to regex or are there special chats in the string? Then you probably want to use http://docs.oracle.com/javase/6/docs/api/java/util/regex/Pattern.html#quote(java.lang.String) on the string before building a pattern. |
| 03:20 | noidi | this post describes how to load a library (clj-stacktrace) automatically in each lein repl. it's for lein1, though, so I don't know if that still works. http://technomancy.us/154 |
| 03:23 | john2x | noidi: nice, clj-stacktrace's readme has instructions for lein2 https://github.com/mmcgrana/clj-stacktrace#leiningen |
| 03:35 | wei_ | is noir required to use the fetch library? |
| 03:36 | antares_ | wei_: no, fetch is something client-side |
| 03:37 | wei_ | so how do i add my remote on the server? I'm using compojure |
| 03:38 | abp | wei_: I just use that: https://github.com/shoreleave/shoreleave-remote-ring |
| 03:40 | wei_ | thanks abp, looks good. this doesn't require any other part of shoreleave does it? |
| 03:41 | abp | wei_: shoreleave-remote for the client part. |
| 03:41 | wei_ | right. |
| 03:42 | abp | wei_: Beware, the samples of shoreleave-remote-ring have wrong namespaces in the require statements, it's cemerick.shoreleave.rpc, not port79.rpc |
| 03:56 | wei_ | it works! I'm constantly surprised at how easy it is to get things done in clojure |
| 03:58 | mrhanky | hi, i'm using clojure on macosx. i cant use the arrow keys to go through my inputs. i get ^[[A, ^[[B, ^[[C, ^[[D |
| 03:58 | mrhanky | how can i fix that? i'm using bash as shell |
| 03:59 | hiredman | mrhanky: clojure's built in repl doesn't support any kind of line editing or history |
| 03:59 | mrhanky | hm |
| 03:59 | wei_ | are you using leiningen? |
| 03:59 | hiredman | you can use an external program like rlwrap or something like jline |
| 04:00 | mrhanky | i'm totally new to clojure, just downloaded it. my professor told me that arrow keys are working, but he's on windows |
| 04:01 | hldfr | hmm is it true that any data structure that implements first, cons, rest, on that any of clojure sequence library functions can be applied ? |
| 04:02 | mrhanky | another guy on osx has the same issue with the arrow keys |
| 04:03 | hiredman | mrhanky: most likely because the windows terminal is providing line editing |
| 04:03 | hldfr | also, are all clojure sequence lib functions defined in terms of first, cons, rest or another seq lib function ? |
| 04:04 | wei_ | mrhanky: try following the directions here: http://clojure-doc.org/articles/tutorials/getting_started.html |
| 04:05 | wei_ | it'll give you a better repl, with working arrow keys. though, my clojurescript repl isn't so nice.. |
| 04:05 | abp | wei_: What do you use for cljs? |
| 04:06 | wei_ | lein cljsbuild |
| 04:06 | wei_ | for the repl, lein trampoline cljsbuild repl-listen |
| 04:08 | abp | wei_: Ah ok, do you know how to switch into my apps namespace in the cljs-repl? |
| 04:09 | abp | wei_: Do I have to load-namespace? |
| 04:09 | wei_ | i just use (ns my-app.namespace) |
| 04:10 | wei_ | the namespace gets loaded when you refresh the page |
| 04:14 | abp | wei_: Everytime I use something that's required in my file, the cljs repl hangs |
| 04:16 | wei_ | me too- it's waiting for the page to connect. do you have a subsequent (repl/connect ("localhost:9000/repl"))? if so, the repl should unhang when you refresh the page. |
| 04:17 | abp | wei_: Yes, everytime the page is ready |
| 04:17 | abp | wei_: Will experiment a little more then, thanks. |
| 04:27 | Kototama | hi, any ideas what is the problem with 'lein autodoc' http://paste2.org/p/2353617 ? |
| 04:28 | mpenet | Kototama: you are on windows? |
| 04:28 | hyPiRion | Kototama: What operative system are you using? |
| 04:33 | hyPiRion | Regardless, it seems like autodoc isn't built for Leiningen 2.0 |
| 04:34 | Kototama | i'm using linux ubuntu 12.04 |
| 04:35 | hyPiRion | And you're using leiningen 2 or 1? (check by doing 'lein version') |
| 04:35 | Kototama | lein 2 |
| 04:37 | Kototama | i'll try the JAR with the command line |
| 04:37 | hyPiRion | Yeah, that seems to be the issue: https://github.com/tomfaulhaber/lein-autodoc/blob/master/src/leiningen/autodoc.clj#L4 |
| 04:38 | hyPiRion | Autodoc is built for 1.x only (as of right now)- though it would be easy to fix that. |
| 04:46 | Kototama | strange I got a lot of file not found exception |
| 04:48 | Kototama | maybe i'll just use the codox plugin instead |
| 04:50 | hyPiRion | Kototama: Seems like a solution for now, unless you're depending on autodoc. |
| 04:51 | hyPiRion | Strange that it's not updated though. |
| 04:58 | wei_ | has anyone gotten the extensible reader to work between clj and cljs? I'm trying to serialize mongo ObjectIds. |
| 05:05 | Kototama | oh yeah... now I have a super error with lein ring uberwar http://paste2.org/p/2353714 |
| 05:38 | Kototama | ah... solved. It seems one of the plugin needed a version of clojure > 1.4.0 |
| 05:38 | Kototama | it's always complicated this uberwar builds :-s |
| 07:47 | edv | -clear |
| 07:47 | edv | argh |
| 07:50 | jballanc | what? where'd all my backlog go? |
| 07:50 | jballanc | ;-) |
| 08:32 | bordatoue | hello could anyone please tell me how to use search with lein |
| 08:46 | gkovoor | s |
| 09:03 | bordatoue` | hello could anyone help me with lein command |
| 09:05 | jsabeaudry | bordatoue`, pose ta question |
| 09:05 | antares_ | jsabeaudry: already answered in #leiningen |
| 09:05 | bordatoue` | jsabeaudry: i had an issue with lein search command , using lein version 2 |
| 09:06 | jsabeaudry | antares_, great! I really need to add some timestamps here |
| 09:07 | bordatoue` | jsabeaudry: antares did answer my question from #leiningen |
| 10:24 | supertramp | hi |
| 10:24 | supertramp | guys - how to trace function exection? |
| 10:24 | supertramp | is there something better than tools.trace? |
| 10:26 | stuartsierra | supertramp: try a JVM profiler/debugger |
| 10:26 | duck11231 | You could use Lamina's probe channels. https://github.com/ztellman/lamina/wiki/Probes-and-Instrumentation |
| 10:29 | supertramp | thanks - but I'm looking for some kind of tree-like structure where actual argument expansion & eval could be seen |
| 10:30 | TimMc | YOu want a stepping debugger. |
| 10:32 | oich | does this not work because it has "get" in the method name: (Integer |
| 10:32 | oich | (Integer/getInteger "3") |
| 10:34 | TimMc | No, Clojure doesn't do bean-y stuff. |
| 10:35 | TimMc | oich: It's just that Integer/getInteger is not what you think it is. |
| 10:35 | sunkencityryleh | How can I print out what kind of variable a variable is? |
| 10:35 | TimMc | sunkencityryleh: class ? |
| 10:35 | oich | I think it returns Integer, like in java. (Integer/parseInt "3") works. |
| 10:35 | TimMc | sunkencityryleh: And you probably mean a value, not a variable. |
| 10:36 | TimMc | oich: No, go look at the docs. |
| 10:36 | sunkencityryleh | TimMc: ah! thanks. |
| 10:36 | TimMc | oich: http://docs.oracle.com/javase/6/docs/api/java/lang/Integer.html#getInteger%28java.lang.String%29 |
| 10:37 | oich | ah.... I'm an idiot... ok |
| 10:37 | TimMc | No, it's just a really, really weird thing to have in the Integer class. |
| 10:37 | supertramp | TimMc: probably yes - what do you use? |
| 10:37 | TimMc | supertramp: I don't. There's CDT, for Emacs... but I haven't gotten around to learning how to use it. |
| 10:38 | supertramp | TimMc: so how you do debug? |
| 10:38 | TimMc | println :-P |
| 10:38 | supertramp | ah :) |
| 10:39 | stuartsierra | logging |
| 10:39 | stuartsierra | Breaking apart fns and testing them at the REPL. |
| 10:40 | duck1123 | I'm a big fan of clojure.tools.logging/spy for debugging |
| 10:40 | TimMc | You can also drop in a spy macro that prints whatever it is wrapped around. |
| 10:43 | supertramp | there is dotrace but I'm not sure how to use it yet .. :} |
| 10:43 | supertramp | in tools.trace |
| 10:48 | supertramp | I'm getting always: IllegalStateException Can't dynamically bind non-dynamic var: user/foo clojure.lang.Var.pushThreadBindings (Var.java:353) |
| 10:49 | ToBeReplaced | for those who use enlive... do you usually keep your templates in src? i thought i'd put them in resources/public, but then i'd have to do some sorcery to always change the path in deftemplate |
| 10:49 | tbaldridge | supertramp: example code? |
| 10:50 | supertramp | tbaldridge: any that uses old clojure.contrib package I think |
| 10:50 | TimMc | supertramp: Declare the var with :dynamic |
| 10:50 | TimMc | Oh, there's your problem. |
| 10:50 | TimMc | ~contrib |
| 10:50 | clojurebot | Monolithic clojure.contrib has been split up in favor of smaller, actually-maintained libs. Transition notes here: http://dev.clojure.org/display/design/Where+Did+Clojure.Contrib+Go |
| 10:51 | TimMc | ...and more importantly, monolithic contrib stopped being maintained at 1.2. |
| 10:51 | supertramp | TimMc: I'm using new one :) but there is dotrace behaving differently I think .. |
| 10:52 | supertramp | tbaldridge: for example this one: http://forum.pclayer.com/post39501.html |
| 10:53 | supertramp | if I use (use 'clojure.tools.trace) instead I got that exception |
| 10:53 | AWizzArd | Do we have a CCW user here? A friend just downloaded the newest Eclipse and newest version of CCW and wants to use a Leiningen project. We noticed that compiled classes go into the project root, into a folder classes/, but not into target/classes/. Could any CCW user try to verify this? |
| 10:53 | TimMc | supertramp: What does *clojure-version* tell you? |
| 10:53 | supertramp | 1.4.0 |
| 10:54 | supertramp | with org.clojure/tools.trace "0.7.3" |
| 10:55 | TimMc | OK, maybe trace is trying to bind your fn. |
| 10:56 | TimMc | Try putting ^:dynamic in front of your fn's name, after "defn". |
| 10:57 | supertramp | TimMc: great - works! :) what's the magic? :) |
| 10:58 | TimMc | supertramp: Clojure 1.3 introduced a constraint on vars that to use dynamic binding on one, it needs to be declared as such. |
| 10:58 | TimMc | dotrace is trying to dynamically bind your fn |
| 10:59 | wkelly | 1 |
| 10:59 | TimMc | supertramp: Do this in your terminal: (macroexpand-1 '(dotrace [foo] (foo 1))) |
| 10:59 | wkelly | sorry! |
| 11:00 | supertramp | thanks TimMc! :) |
| 11:24 | frozenlock | I'm looking for an installation wrapper that allows clojure jar to run at startup. There's packjacket, but it seems to crash with any clojure jar. Any other suggestions? |
| 11:25 | jcromartie | frozenlock: are you trying to create a distributable package? |
| 11:26 | jcromartie | like, a standalone app, or what? |
| 11:26 | frozenlock | yeah, like that :P |
| 11:26 | jcromartie | is this a standalone GUI app, or a command-line tool |
| 11:26 | jcromartie | and what installer are you using? |
| 11:27 | frozenlock | I would say neither, it should run as a service/daemon. |
| 11:27 | jcromartie | ah ha OK |
| 11:27 | jcromartie | for a specific platform? |
| 11:28 | TimMc | You should be able to use any JAR-accepting utility. |
| 11:29 | TimMc | Just make sure it's an uberjar that runs with java -jar. |
| 11:29 | frozenlock | Well the service part for windows is more important, as I expect linux users to be able to it themself (but of course it would be a nice addition) |
| 11:29 | jcromartie | OK well now it gets tricky |
| 11:30 | jcromartie | how about http://wrapper.tanukisoftware.com/doc/english/introduction.html |
| 11:30 | jcromartie | and for simplicity, you should bundle your dependencies and Clojure source code into a standalone jar |
| 11:30 | jcromartie | are you using Leiningen? |
| 11:31 | frozenlock | yes, it's all in a uberjar like TimMc said. |
| 11:32 | frozenlock | The jar works flawlessly, it's just the installation/service part that confuses me. |
| 11:32 | frozenlock | Trying the tanukisoftware now :) |
| 11:32 | jcromartie | well the wrapper just takes a jar and a startup or handler class I'd assume |
| 11:33 | jcromartie | basically, set up the main .jar, main class, and arguments |
| 11:33 | jcromartie | should work |
| 12:00 | supertramp | is it possible to 'reset' REPL somehow? |
| 12:01 | nDuff | supertramp: ...well, you can switch to a new namespace... |
| 12:02 | babilen | seancorfield: thanks! (for clj-1066) |
| 12:02 | supertramp | nDuff: well I have source file - loaded with lein - do a change to file and want to rerun it with that change from repl |
| 12:02 | supertramp | nDuff: is it possible? |
| 12:03 | supertramp | without quit / run repl by lein again ... |
| 12:03 | nDuff | supertramp: Perhaps the :reload keyword to use is what you're looking for? |
| 12:06 | supertramp | cool :) |
| 12:06 | supertramp | thanks nDuff! :) |
| 12:15 | ToBeReplaced | does anyone know of any static code analyzers for clojure other than kibit? |
| 12:16 | AWizzArd | ToBeReplaced: FindBugs |
| 12:17 | seancorfield | babilen: not sure why you're thanking me for that ticket but "you're welcome!" on their behalf :) |
| 12:18 | babilen | seancorfield: err, I meant to thank Stuart. Somehow that name was shadowed by yours. I am sure that I could thank you for other things, so ... just keep it :) |
| 12:19 | babilen | stuarthalloway: thanks for fixing CLJ-1066! |
| 12:19 | ohpauleez | ToBeReplaced: There's also Eastwood, but it's unclear what it's state is, and it's not entirely "static" |
| 12:19 | ohpauleez | it operates at the bytecode level |
| 12:19 | ohpauleez | you could also AOT a file and run it through bytecode static analyzers for the JVM |
| 12:20 | ohpauleez | (As suggested by AWizzArd) |
| 12:21 | ToBeReplaced | yea; i'll take a look a both and other jvm options. thanks |
| 12:42 | Sgeo | reduce always walks the entire seq except in new Clojure with reduced? |
| 12:42 | Sgeo | :/ |
| 12:43 | jcromartie | yes, reduce produces a single result value |
| 12:43 | Sgeo | "reduce produces a single result value" does not in fact answer the question. |
| 12:44 | jcromartie | the only way to reduce a seq is to walk the whole thing |
| 12:44 | Sgeo | Not true. |
| 12:44 | jcromartie | no? |
| 12:44 | clojurebot | no is tufflax: there was a question somewhere in there, the answer |
| 12:44 | gfredericks | is it 1.5 that lets you short-circuit? |
| 12:45 | Sgeo | Haskell's foldr can stop, and thus works even on infinite lists. It's possible there thanks to pervasive lazyness (or is it non-strictness)? |
| 12:45 | jcromartie | ah, so you are just talking about reducing over a subset of the reduction |
| 12:45 | jcromartie | a subset of the seq |
| 12:45 | Sgeo | jcromartie, suppose I'm reducing with some sort of short-circuiting * |
| 12:46 | Sgeo | And the seq looks like [1 2 3 0 4 5 6] |
| 12:46 | jcromartie | so like, (reduce + [1 2 3 0 4 5 6] :whille pos?) |
| 12:46 | jcromartie | or something like that |
| 12:49 | Sgeo | Why shouldn't I be able to write something like (reduce * [1 2 3 4 5 0 6 7 8 9 10]) and have the reduce stop as soon as it can determine the answer, when it hits 0 |
| 12:49 | technomancy | Sgeo: that's exactly the point of the changes in 1.5 |
| 12:49 | Sgeo | codeeval.com seems to be stuck on 1.2 :( |
| 13:07 | bosie | what does "seq-exprs" in the docs mean? |
| 13:08 | bosie | e.g. http://clojuredocs.org/clojure_core/clojure.core/for |
| 13:10 | TimMc | bosie: You mean coll-exprs? |
| 13:11 | TimMc | expressions that evaluate to collections |
| 13:11 | bosie | TimMc: so a body-expr is an expresion that evaluates to a body? |
| 13:11 | TimMc | Nope. |
| 13:13 | TimMc | That means the expression that forms the body of the larger form. |
| 13:13 | TimMc | It's not consistent naming. |
| 13:15 | pandeiro | is there a way to find out what version of clojurescript is running at the clojurescript repl? |
| 13:28 | hyPiRion | *clojure-version* ? |
| 13:29 | dnolen | pandeiro: there is not, that would be a useful addition |
| 13:33 | pandeiro | dnolen: what was the thinking behind the #_=> prompt? |
| 13:33 | pandeiro | so code could be pasted from the repl and evaled? |
| 13:34 | hyPiRion | easier copy-pasting, I assume |
| 13:34 | pandeiro | yeah makes sense |
| 13:35 | pandeiro | i had forgotten about the #_ reader macro |
| 13:37 | jamii | how can I have a macro produce a dynamic var? this doesn't work - https://gist.github.com/3919505 |
| 13:41 | jamii | It looks like the ^:dynamic is getting applied to the splice rather than being present in the generated code |
| 13:44 | jamii | aha, it can be applied before the splice: |
| 13:44 | jamii | (defmacro defdyn [name] |
| 13:44 | jamii | `(def ~(with-meta name (assoc (meta name) :dynamic true)))) |
| 13:46 | hyPiRion | vary-meta is probably better |
| 13:46 | hyPiRion | (defmacro defdyn [var] #_=> `(def ~(vary-meta var assoc :dynamic true))) |
| 13:47 | hyPiRion | Or more succinct, at least. |
| 13:48 | jamii | hyPiRion: thanks |
| 13:51 | Sgeo | jamii, thought: You might want to have *print-meta* be true at the REPL? |
| 13:51 | jamii | Sgeo: I do, you can see the meta in the gist I posted |
| 13:51 | Sgeo | Oh, ok |
| 14:14 | ohpauleez | dnolen: http://dev.clojure.org/jira/browse/CLJS-395 - Node.js bug is elusive and seems to be an isolated case. I also have a couple of updated patches to push to Jira (with-out-str, etc) |
| 14:20 | dnolen | ohpauleez: did you try building clojurescript from scratch to repro? |
| 14:21 | ohpauleez | yeah - followed his directions to repro and nothing |
| 14:21 | ohpauleez | looked through the code |
| 14:21 | ohpauleez | the code changed a little (removed an unnecessary if) - but nothing is reproducting |
| 14:21 | ohpauleez | tried JDK 1.6 and 1.7 |
| 14:21 | ohpauleez | tried Linux and OS X |
| 14:22 | dnolen | ohpauleez: yeah unless we get more input from him will be hard to track. that's cool about the other patches. |
| 14:22 | ohpauleez | dnolen: Cool - moved it to minor, I'll just keep an eye on it to see if anyone else posts to it |
| 14:39 | Baldanders | I'm trying to get leiningen 2.0.0-preview10 working under Windows7. I put lein.bat and the matching standalone jar in c:\lein, added that to my path, and set LEIN_JAR to that path as well. If I try to run lein anything I get the error: "Error: Could not find or load main class clojure.main" Anyone know if I did something wrong? |
| 14:40 | hiredman | Baldanders: I imagine LEIN_JAR should point to the actual jar? |
| 14:41 | Baldanders | ah, OK, that is probabl;y it then- I expected it to be a path... |
| 14:43 | Baldanders | Indded that seems to have done it- it is downloading jars now. Thanks. |
| 14:45 | wingy | is it allowed to search for partners here? |
| 14:46 | wingy | making the next big thing (billion market) .. if anyone with experience in clojure (datomic) wanna participate .. give me a message |
| 14:46 | technomancy | heh |
| 14:47 | ystael | technomancy: am I correct in thinking that when leiningen says "java.lang.String cannot be cast to clojure.lang.IPersistentCollection" what it means is "you spelled your project.clj or profiles.clj wrong" ? |
| 14:48 | technomancy | ystael: likely |
| 14:48 | wingy | at least i am honest :) |
| 14:52 | muhoo | ystael: more likely, you have {: foo "bar"} somewhere that it wants {:foo ["bar"]} |
| 14:52 | muhoo | happens all the damn time |
| 14:53 | muhoo | sorry {:foo "bar"} where it wants {:foo ["bar"]} ... grr ssh lag |
| 14:53 | aperiodic | would the casting error be to ISeq in that case? |
| 14:54 | muhoo | it wants a seq, [] or () |
| 14:56 | ystael | wait. i thought :mirrors in user profile in profiles.clj was supported now? |
| 14:57 | aperiodic | oh right, strings totally suport ISeq, duh |
| 14:57 | muhoo | ,(first "foobar") |
| 14:57 | clojurebot | \f |
| 14:58 | technomancy | not technically ISeq, but an approximation thereof |
| 14:59 | scriptor | ,(class (seq "foo")) |
| 14:59 | clojurebot | clojure.lang.StringSeq |
| 15:00 | scriptor | hmm, looks like it extends ASeq, which implements ISeq |
| 15:00 | gfredericks | but the string class doesn't |
| 15:00 | scriptor | ah, right |
| 15:01 | aperiodic | yeah, it's handled here: https://github.com/clojure/clojure/blob/master/src/jvm/clojure/lang/RT.java#L479 |
| 15:01 | muhoo | i remember seeing a map/chart somewhere of all the IStuff that all the clojure types support |
| 15:01 | muhoo | like a bit inheritance tree |
| 15:03 | muhoo | s/bit/big/ (fucking TYPING, how does it work?) |
| 15:04 | stuarthalloway | I declined http://dev.clojure.org/jira/browse/CLJ-1025, if any CLJS committers want to yell at me I am here ;-) |
| 15:05 | cemerick | stuarthalloway: I already have a fix for cljs that makes it irrelevant: https://gist.github.com/3918764 |
| 15:05 | stuarthalloway | cemerick: great! |
| 15:08 | Baldanders | Hmm- when I try to run lein it goes out and starts getting jars from maven, but it hangs trying to get core.cache |
| 15:09 | stuartsierra | ClojureScript release 0.0-1513: http://build.clojure.org/job/clojurescript-release/18/ |
| 15:12 | frozenlock | \o/ |
| 15:12 | nDuff | Huh -- I'm getting reflection warnings on (doto *err* (.write "foo") (.flush)). Surprised it isn't known to be java.io.Writer as the docs imply. |
| 15:14 | dnolen | stuartsierra: sweet |
| 15:17 | Baldanders | I found an issue on the leiningen page about the maven servers being very slow, but it was closed, saying that mirror support had been added. Anyone know if this is still a problem? I'm wondering if it will eventually manage to get it or if it is just completely hung. |
| 15:27 | emezeske | stuartsierra: Thanks! |
| 15:48 | amalloy | &(meta #'*err*) |
| 15:48 | lazybot | ⇒ {:ns #<Namespace clojure.core>, :name *err*, :added "1.0", :doc "A java.io.Writer object representing standard error for print operations.\n\n Defaults to System/err, wrapped in a PrintWriter"} |
| 15:48 | `fogus | stuartsierra: Thanks! |
| 15:57 | lynaghk | `fogus: re: your question a few days ago (sorry, I was out of town and left IRC on): did you want to exclude a namespace from from a CLJX file or want to exclude an entire namespace from being shared between runtimes? |
| 16:02 | rlb | Is there a naming convention for macros that set up a let binding i.e. (with-thing-involving-complicated-setup thing body-using-thing)? |
| 16:03 | rlb | i.e. is that an unexpected (and unwanted) use of "with-"? |
| 16:04 | technomancy | rlb: with- is typically used for macros that take a body, yeah |
| 16:04 | rlb | just didn't know if having the caller specify the binding name was something people would expect in clojure. |
| 16:05 | rlb | i.e. (with-foo bar (do-something bar)) |
| 16:05 | amalloy | rlb: yes, very much expected. the opposite is usually a surprise |
| 16:05 | rlb | I know about (with-foo [bar ...] (do-something bar)), but that's different. |
| 16:05 | amalloy | it's not really necessary, but you could also require a vector there, because vectors often visually imply a new binding: (with-foo [bar] (do-something bar)) |
| 16:06 | rlb | amalloy, technomancy: right, and thanks. |
| 16:07 | ghadishayban1 | Can anyone in core recommend how to deal with CLJ-1082? |
| 16:08 | hiredman | emacs will nicely indent bodies for forms that start with with- |
| 16:08 | ghadishayban1 | or I can throw some ideas on clojure-dev... |
| 16:09 | amalloy | i'm kinda surprised subvec works on primitive vectors, even, just because they're so rarely used |
| 16:10 | hiredman | seems pretty straight forward |
| 16:10 | hiredman | ghadishayban1: is it beyond just changing the cast to IPV? |
| 16:10 | hiredman | oh, I guess IPV doesn't specify a ranged iterator |
| 16:11 | ghadishayban1 | yeah |
| 16:11 | hiredman | spit balling on clojure-dev is not a bad idea |
| 16:12 | hiredman | you could turn rangeIterator in to a rhickey special |
| 16:12 | hiredman | a static method with instanceof checks + an interface |
| 16:12 | hiredman | make gvecs extend the interface |
| 16:13 | ghadishayban1 | i'll try that. thanks! |
| 16:19 | ghadishayban1 | i wanted to fold without boxing… i might just wrap an array |
| 16:20 | ghadishayban1 | and sling CollFold onto it |
| 16:22 | hiredman | ghadishayban1: ah, so in that case you need to have gvec create it's own distrinct subvecs that support folding without the iterator бизнес |
| 16:23 | ghadishayban1 | i considered making what you're calling the rhickey special check in subvec fn itself |
| 16:23 | ghadishayban1 | but subvec is used early in bootstrapping |
| 16:23 | technomancy | trying to think of examples of things that can be = but do not print the same |
| 16:23 | technomancy | order in sets and maps is the only thing I can think of, but it's interesting |
| 16:23 | hiredman | lists and vectors or course |
| 16:23 | hiredman | of |
| 16:23 | technomancy | oh of course |
| 16:23 | ghadishayban1 | yep |
| 16:23 | amalloy | (reify Object (equals [this other] true)) |
| 16:24 | technomancy | ~gourds |
| 16:24 | clojurebot | SQUEEZE HIM! |
| 16:24 | technomancy | amalloy: equals is broken java equality though |
| 16:24 | amalloy | still passes the = check |
| 16:24 | technomancy | huh |
| 16:25 | technomancy | anyway I was thinking of function equality |
| 16:25 | technomancy | seems safe to consider functions equal if they differ only on the name of the parameters |
| 16:26 | hiredman | technomancy: what about closures? |
| 16:26 | amalloy | and have identical closures |
| 16:26 | technomancy | of course |
| 16:26 | technomancy | anyway made me realize that c.c/= is technically not egal since egal is defined in terms of operational equivalence |
| 16:27 | technomancy | and printing differently is a violation of operational equivalence |
| 16:27 | technomancy | so I think it's OK by the rules of =, but not by the rules of egal, but that's ok in practice |
| 16:27 | amalloy | lists and vectors are a more obvious violation |
| 16:27 | technomancy | yeah not sure why I didn't think of that first =) |
| 16:28 | amalloy | well i meant, they violate it in more than just printing differently |
| 16:28 | amalloy | &(map (juxt pop (memoize pop)) [[1 2 3] '(1 2 3)]) |
| 16:28 | lazybot | ⇒ ([[1 2] [1 2]] [(2 3) [1 2]]) |
| 16:29 | technomancy | haha |
| 16:29 | technomancy | geez |
| 16:33 | pandeiro | Raynes: does tentacles have anything to deal with gists? |
| 16:34 | Raynes | tentacles.gist |
| 16:34 | Raynes | tentacles.gists, even |
| 16:35 | pandeiro | Raynes: sorry, was reading the blog post and skipped the last graph |
| 16:35 | pandeiro | what i wanted to give a gist ID and get back datums |
| 16:36 | Raynes | (tentacles.gists/specific-gist someid) |
| 16:36 | pandeiro | beautiful, just found it, thanks |
| 16:43 | frozenlock | Is there an equivalent of this: 'content-type "application/json; charset=utf-8"', but for a clojure map instead of json? |
| 16:43 | nDuff | frozenlock: Not a standardized type, no. |
| 16:43 | dakrone | frozenlock: application/clojure |
| 16:43 | nDuff | frozenlock: the x-* namespace is around for more free-form usage. |
| 16:44 | frozenlock | Excellent, thank you very much! |
| 16:44 | technomancy | istr the x- prefix being deprecated |
| 16:45 | nDuff | Hmm. I could be behind on that. |
| 16:46 | stuartsierra | I've started using application/x-edn |
| 16:48 | xeqi | http://tools.ietf.org/html/rfc6648 : x- being deprecated |
| 16:50 | frozenlock | stuartsierra: edn? |
| 16:50 | stuartsierra | https://github.com/edn-format/edn |
| 16:51 | hiredman | the x stands for extendable |
| 16:51 | technomancy | it's like clojure but ... actually yeah just that. |
| 16:52 | frozenlock | :) |
| 16:53 | stuartsierra | It's a subset: no fns, no regexes |
| 16:53 | amalloy | xeqi: it checks out: publication date is not april first. probably legit |
| 16:53 | Raynes | stuartsierra: What color is your hair this year? |
| 16:53 | stuartsierra | I haven't decided yet. |
| 16:54 | Raynes | My hair is way too natural. Needs to get molested by chemicals again soon. |
| 16:54 | stuarthalloway | stuartsierra: you don't have much time left to change the median hair color for the year |
| 16:54 | stuartsierra | I think I've already passed that point. |
| 17:00 | gfredericks | using OOP makes me sad :( |
| 17:00 | Sgeo | So, not a Smalltalk fan? |
| 17:00 | Sgeo | :D |
| 17:00 | gfredericks | ruby in this case |
| 17:01 | Sgeo | Ruby is a grossified Smalltalk |
| 17:01 | gfredericks | you try to program with functions and values and it's just too awkward and the language pushes you back to stateful classes |
| 17:01 | duck1123 | I liked Ruby before I learned Clojure |
| 17:02 | technomancy | supposedly ruby added currying and first-class methods in 1.9, but I haven't been able to figure it out |
| 17:02 | scriptor | currying? |
| 17:02 | scriptor | or just partial application? |
| 17:02 | technomancy | partial application, but they call it currying IIRC |
| 17:02 | scriptor | ah |
| 17:03 | duck1123 | I realized I was ruined by Clojure when I caught myself trying to do. some_array.map(:title) in Ruby |
| 17:04 | technomancy | also, I use the term "first class" loosely |
| 17:06 | scriptor | technomancy: hmm, it actually seems like real currying |
| 17:07 | gfredericks | so tired of having four different ways to make a function |
| 17:07 | gfredericks | and by 'four' I probably mean 'ten' |
| 17:09 | duck1123 | just earlier today I finished watching "Clojure is my favorite Ruby" http://youtu.be/PCdEbUBk6a0 Had that same complaint |
| 17:10 | technomancy | gfredericks: the distinctions between which can change between patchlevels |
| 17:10 | amalloy | scriptor: link? |
| 17:11 | technomancy | or maybe that was between "bugfix" version releases; it's been a while |
| 17:11 | scriptor | amalloy: just skimmed through http://pragdave.blogs.pragprog.com/pragdave/2008/09/fun-with-procs.html |
| 17:11 | gfredericks | technomancy: don't make me cry |
| 17:11 | gfredericks | I just found out the other day that `-42` and `- 42` are semantically different expressions |
| 17:11 | scriptor | I'm still not positive on the difference, though, so I'm probably wrong |
| 17:12 | technomancy | scriptor: real currying wouldn't require having to call .curry first |
| 17:12 | amalloy | right. it would implicitly work on every function |
| 17:12 | gfredericks | technomancy: so you're saying that any method called 'curry' is automatically wrong? :) |
| 17:13 | technomancy | gfredericks: unless it's in the compiler =) |
| 17:13 | Sgeo | Haskell has a function called curry |
| 17:13 | scriptor | does it have to be done implicitly? |
| 17:13 | technomancy | scriptor: well this is somewhere between |
| 17:13 | amalloy | gfredericks: it could just return "http://www.haskell.org/wikiupload/8/86/HaskellBCurry.jpg" |
| 17:13 | Sgeo | It isn't needed usually, but can be useful |
| 17:13 | scriptor | as far as I can tell .curry just returns a curried version, which you can then partially apply on |
| 17:14 | scriptor | true |
| 17:14 | technomancy | since it happens implicitly once you've transformed a regular lambda into a curryable one |
| 17:14 | TimMc | amalloy: All hail! |
| 17:14 | scriptor | theoretically, the interpreter could just call .curry on all functions internally |
| 17:15 | technomancy | scriptor: unless there are rest args |
| 17:15 | scriptor | right, or splats as those people call it |
| 17:15 | gfredericks | also the default args |
| 17:16 | gfredericks | are a problem |
| 17:16 | gfredericks | of similar flavor |
| 17:16 | gfredericks | not to mention blocks |
| 17:24 | callen | http://lisp-univ-etc.blogspot.com/2012/10/lisp-hackers-francois-rene-fare-rideau.html I found this interesting. What I found particularly interesting was the commentary on the social issues of the Lisp community. Particularly since the last time myself or technomancy noted such issues, there was a lot of loud bluster about how we couldn't possibly make such a sweeping gesture. |
| 17:30 | frozenlock | Is there something like a reverse destructuring? I often find myself doing a map like so: {:arg arg :arg2 arg...} |
| 17:30 | gfredericks | useful has keyed |
| 17:31 | gfredericks | I haven't seen it anywhere else |
| 17:31 | gfredericks | I've wanted it 40 times at least though |
| 17:31 | gfredericks | but always just barely not enough to use useful |
| 17:31 | gfredericks | I take it back, I brought in useful once. |
| 17:31 | frozenlock | Thanks, I'll take a look |
| 17:32 | frozenlock | But indeed bringing a library just for that... eh.. |
| 17:32 | duck11232 | I keep telling myself that useful has things I want, but since it's not already on my classpath, i don't use it |
| 17:33 | frozenlock | Oh why doesn't github autofocus me on the search bar I wonder... |
| 17:34 | technomancy | duck1123: which is why someone needs to wire up convenience functions around pomegranate and the repl |
| 17:35 | aperiodic | this might not be a clojure question, but how would i go about tunneling clj-http requests through a socks proxy or whatnot? |
| 17:35 | dakrone | aperiodic: the docs on the github page have instructions for using a proxy |
| 17:36 | aperiodic | dakrone: awesome! thanks |
| 17:38 | amalloy | duck11232: solution: add useful to your lein-new templates? |
| 17:38 | dnolen | callen: that interview doesn't talk about social issues in the overall CL community at all. rather CL's lack of modularity exacerbates large scale software development according to Fare. |
| 17:42 | technomancy | callen: woo cybernetics |
| 17:43 | TimMc | Such a small world. |
| 17:43 | TimMc | Especially when you live in Boston. :-P |
| 17:44 | technomancy | half a million lines of CL... good grief. |
| 17:50 | technomancy | callen: holy smokes; asdf wasn't self-upgradeable until *2010* |
| 17:50 | technomancy | mind blown |
| 17:52 | scriptor | so it's a dependency manager that wouldn't fetch any dependencies you didn't have? |
| 18:06 | aperiodic | dakrone: is there any way to proxy with SOCKS? |
| 18:07 | dakrone | aperiodic: I thought the existing proxy support worked with socks |
| 18:11 | aperiodic | dakrone: when i point it at my socks server (:proxy-host "127.0.0.1", :proxy-port 9999, the socks server is just ssh -D 9999) i get org.apache.http.NoHttpResponseException: the target server failed to respond |
| 18:12 | aperiodic | hmm, this might be user error; i'll dig into it and get back to you |
| 18:13 | dakrone | aperiodic: I'll also take a look |
| 18:22 | TEttinger | hmm, I am looking for an animation library for swing, preferably one with idiomatic Clojure bindings |
| 18:23 | TEttinger | I might have to resort to Quil, despite it being an absolute mess every time I try to run a demo |
| 18:24 | ebaxt | I'm trying to deploy to clojars, but I'm getting "Failed to deploy artifacts/metadata: No connector available to access repository clojars-https (clojars-https) of type default using the available factories FileRepositoryConnectorFactory, WagonRepositoryConnectorFactory". Anyone know what I have to do to fix it? I'm using Leiningen 2.0.0-preview10. |
| 18:38 | technomancy | ebaxt: do you have any plugins? it's not able to find the https connector that ships with aether for some reason. |

| 18:52 | patchwork1 | Hey guys, what do we use to emit xml nowadays? |
| 18:52 | patchwork1 | I am running into this problem with clojure.xml |
| 18:52 | patchwork1 | http://stackoverflow.com/questions/2463129/roundtripping-xml-in-clojure-using-clojure-xml-parse-and-clojure-xml-emit?rq=1 |
| 18:52 | lynaghk | patchwork1: emit from what? I tend to just use Hiccup |
| 18:53 | SurlyFrog | Anyone familiar with clojure.java.jdbc? I'm wondering if there is a way to update a row, based on the value that is currently in that row. As in an SQL: 'UPDATE foo SET i = i + 1, j = j + 1 ….' I see `update-values`, but am not sure that it gives me back each matching row. |
| 18:53 | patchwork1 | Well, I am parsing an xml file into whatever format clojure.xml creates, changing a value, and now I want to emit that same structure back into a string |
| 18:59 | lynaghk | patchwork1: ah. not familiar with that workflow, sorry. |
| 19:05 | ebaxt | technomancy: removed all my plugins, delete the entire ~./m2/repository and still no go. Tried my other machine with lein 2.0.0-preview7 but same problem. Any tips to where I should start digging? |
| 19:06 | SurlyFrog | Nevermind my JDBC question, it gets done using `do-commands` |
| 19:15 | metellus | I have a function that I want to modify a map if a series of nested conditions are true and just return the map otherwise. Is there a nice way to do that? |
| 19:16 | S11001001 | metellus: depends on the nature of your modifications and conditions |
| 19:17 | technomancy | ebaxt: the problem is that the http connector for aether (called a wagon for whatever reason) isn't found |
| 19:17 | technomancy | ebaxt: usually you see this when you're trying to deploy to some nonstandard repository type like S3 |
| 19:18 | aperiodic | dakrone: it seems to me that the proxy functionality doesn't work with SOCKS (i've got a local SOCKS tunnel open that my web browser is using fine, but i get the same no response exception w/clj-http) |
| 19:18 | technomancy | the fact that aether would be unable to find a wagon that it bundles with itself is bizarre |
| 19:18 | metellus | S11001001: just an assoc-in depending on some of the values inside the map, but it's hard to do without nesting them |
| 19:19 | metellus | I could use if and if-let instead of when, but it gets ugly quickly when I include the same "else" at every step of the way |
| 19:19 | dakrone | aperiodic: okay, could you open an issue on clj-http so I don't forget to work on it? |
| 19:20 | metellus | right now I just wrapped the whole thing in (or ... original-map) and that works but seems weird |
| 19:20 | aperiodic | dakrone: sure thing! |
| 19:21 | dakrone | thanks |
| 19:21 | S11001001 | metellus: maybe you're looking for update-in |
| 19:21 | ebaxt | technomancy: Thx, I'll see what I can figure out. |
| 19:24 | Sgeo | metellus, -?> ? |
| 19:24 | Sgeo | Or some monad? |
| 19:26 | metellus | Sgeo: those does seem more like what I want, but I'd rather stick to clojure.core if I can |
| 19:26 | metellus | thanks though |
| 19:31 | AdmiralBumbleBee | metellus: if you could describe your problem a bit more, I suspect someone would have a better solution |
| 19:33 | emezeske | metellus: Along the lines of what AdmiralBumbleBee just said, a paste of the code you're not happy with would go a long ways |
| 19:35 | julson | noob question... What's a good strategy for working with a largish collection in clojure? I'm trying to keep track of counts mapped to unique strings in a hash map. I would update that map as I take things out of a queue, and it would potentially grow large over a period of time. |
| 19:37 | mefisto | another nooby question - I have a seq of ints, and I'd like to split it up into a seq of seqs of ints, with each split happening after any int less than 32. sort of a modified behavior of partition-with |
| 19:37 | mefisto | *partition-by |
| 19:37 | emezeske | julson: It seems like a regular map would be a fine choice. |
| 19:37 | emezeske | julson: Unless you're talking about something bigger than available RAM, or whatever |
| 19:39 | AdmiralBumbleBee | mefisto: iterate and split-with? |
| 19:39 | AdmiralBumbleBee | though I would think partition-by would work |
| 19:40 | mefisto | partition-by puts the ints less than 32 in their own seq, rather than putting them with the preceding ints |
| 19:41 | AdmiralBumbleBee | mefisto: could you give a before and after seq? |
| 19:42 | julson | emezeske: I was just thinking that with persistent collections, I might end up filling up all the available memory if I keep updating that large map. Maybe I shouldn't worry about it yet. |
| 19:43 | emezeske | julson: You know about the structural sharing in Clojure's maps? |
| 19:43 | mefisto | AdmiralBumbleBee: ok - before: [54 46 38 3 49 39 48 52 6 61 60 52 48 43 12] and after: [ [54 46 38 3] [49 39 48 52 6] [61 60 52 48 43 12] ] |
| 19:43 | technomancy | whether you fill up available memory doesn't really depend on whether the map is immutable or not |
| 19:44 | julson | emezeske: ohh damn! I've read about that! yeah. my bad. |
| 19:46 | julson | I completely forgot about the structural sharing aspect of it. Gotta read up on it again. =D thanks! |
| 19:47 | emezeske | julson: HTH |
| 19:56 | amalloy | mefisto: (useful.seq/partition-between (fn [[before after]] (< before 32)) coll) |
| 19:57 | mefisto | amalloy: thanks! |
| 19:57 | amalloy | you need useful, of course |
| 19:58 | mefisto | naturally |
| 20:06 | ForSpareParts | Could anybody help me debug? Very short: http://pastebin.com/Ds4s71jf |
| 20:06 | ForSpareParts | I don't understand the error message, and it doesn't make it very clear where my error is. I'm assuming I'm overlooking something really dumb? |
| 20:07 | tmciver | ForSpareParts: you need parens around newtimer |
| 20:07 | amalloy | and args to the macro |
| 20:07 | ForSpareParts | Thanks! |
| 20:11 | XPherior | Is it possible to get access to the project map at run time with Leiningen? |
| 20:12 | technomancy | XPherior: sort of, but leiningen isn't designed to be used that way |
| 20:12 | technomancy | what are you really trying to do? |
| 20:12 | XPherior | technomancy: That's the idea I got from the mailing list. |
| 20:12 | XPherior | Okay, here it is. |
| 20:12 | XPherior | I have a function that can take options. But defining those options everytime can be a pain. So I figured, it should be available as a configuration option. |
| 20:13 | XPherior | But using an entirely different file for the config might annoy people using the library |
| 20:13 | XPherior | So, project.clj seemed like a nice place to set configuration information. |
| 20:14 | technomancy | if you're not the end consumer you definitely shouldn't be reading project.clj |
| 20:14 | technomancy | because then it will never work in an uberjar |
| 20:14 | XPherior | Ah, that's true.. |
| 20:14 | XPherior | I guess a separate config file is the way to go then. Where does one put such a file? resources/? |
| 20:15 | technomancy | yeah, typically |
| 20:15 | XPherior | I suppose that will work. |
| 20:15 | technomancy | if you want to get fancy you could offer a choice between reading off the classpath vs having an init function to accept config values at boot |
| 20:15 | XPherior | So are you pretty much a one man operation at Heroku? |
| 20:16 | technomancy | less than that really |
| 20:16 | technomancy | the clojure support for heroku is really simple; it's not nearly enough to keep me busy |
| 20:16 | XPherior | That's too bad. What do you fill your free time with? |
| 20:16 | technomancy | nah, it's better than having it be crazy complicated =) |
| 20:16 | technomancy | right now I'm working on the build pipeline |
| 20:17 | XPherior | That sounds like fun. |
| 20:17 | XPherior | Looking everywhere for Clojure jobs. Hard to come by. |
| 20:17 | XPherior | About to give up, probably. |
| 20:17 | technomancy | easier if you can do remote, but yeah still hard to come by |
| 20:18 | XPherior | I thought about that. Remote would be so freakin' boring. |
| 20:18 | technomancy | depends where you live I guess |
| 20:18 | technomancy | works really well here |
| 20:18 | XPherior | You're in CA? |
| 20:18 | technomancy | no, seattle |
| 20:19 | XPherior | I'm in upstate NY. |
| 20:19 | XPherior | I hear Seattle's great. |
| 20:19 | technomancy | plenty of geek stuff still going on even though I don't see co-workers very often |
| 20:19 | technomancy | it is =) |
| 20:19 | XPherior | I'll give you a buzz if you want to get coffee and talk nerd stuff. I might be up that way in the spring. |
| 20:19 | technomancy | sure |
| 20:20 | XPherior | Plenty of Rails jobs, at any rate. |
| 20:20 | XPherior | There's this place in NYC that does OCaml. I wonder what that's like, hah. |
| 20:21 | technomancy | probably pretty intense if it's high-frequency trading |
| 20:21 | XPherior | Jane Street, yep. |
| 20:24 | XPherior | Perhaps in 5 years it'll be easier. |
| 20:24 | technomancy | the build pipeline I'm on is all short-lived process management stuff; something the JVM is rubbish at |
| 20:24 | technomancy | would love to use ocaml here |
| 20:25 | XPherior | Too late to switch? |
| 20:25 | hiredman | http://ocamlunix.forge.ocamlcore.org/ |
| 20:26 | XPherior | Interesting, hiredman. |
| 20:26 | technomancy | XPherior: yeah, plus I'm the only one who likes it |
| 20:26 | XPherior | technomancy: That doesn't surprise me. I wonder if FP'ers will someday not be the minority. |
| 20:30 | XPherior | An init-function at boot time.. What does that even look like? |
| 20:34 | technomancy | XPherior: or better would be to just take it as an optional argument across all functions that consume it |
| 20:35 | XPherior | I would, but it's a macro that takes & body :( |
| 20:35 | technomancy | macros shouldn't have any actual functionality beyond syntax |
| 20:36 | XPherior | It's not a matter of functional. It's that you can't have variadic and optional arguments, AFAIK |
| 20:36 | XPherior | Functionality, rather |
| 20:38 | technomancy | true |
| 20:38 | technomancy | if you can't avoid rest args then you might have to make dynamic binding the only way to override classpath-based config |
| 20:39 | XPherior | Hm, yeah |
| 20:39 | XPherior | Thanks for the suggestions |
| 20:40 | XPherior | Maybe I'll look into making it a plugin and use it with guzheng |
| 20:40 | XPherior | Eh, who knows |
| 22:06 | shachaf | I heard y'all're "lens h8rs". |
| 22:06 | shachaf | Sgeo: Is that true? |
| 22:09 | shachaf | Lenses are the future, so I hear. |
| 22:17 | Koleman | if you have a function with a third argument that has a default value is it possible to use the threading macro to insert the second argument? |
| 22:25 | Sgeo | The threading macros operate on forms, not functions |
| 22:26 | Sgeo | ,(letfn [(f ([a b] (f a b 3)) ([a b c] (+ a b c)))] (->> 10 (f 1)) |
| 22:26 | clojurebot | #<ExecutionException java.util.concurrent.ExecutionException: java.lang.RuntimeException: EOF while reading> |
| 22:26 | Sgeo | ,(letfn [(f ([a b] (f a b 3)) ([a b c] (+ a b c)))] (->> 10 (f 1))) |
| 22:26 | clojurebot | 14 |
| 22:35 | Koleman | Sgeo: I'm following along with the noir-blog sample adapting it to use monger and I want to pass true to indicate whether to perform an upsert or a regular update. See Gist here: https://gist.github.com/3921746 |
| 22:37 | Sgeo | That -> will expand into something approximately like |
| 22:37 | Sgeo | (repo/upsert user :users) |
| 22:38 | Sgeo | ,(macroexpand-1 '(-> user (repo/upsert :users) ))) |
| 22:38 | clojurebot | (repo/upsert user :users) |
| 22:39 | Koleman | Thinking about it now I can just bind variable for user and pass everything in directly instead of messing around with -> |
| 22:40 | Koleman | I actually screwed up that gist but basically there is supposed to be a function that encrypts the password in that -> call |
