| 18:14 | dobry-den | Is there a Clojure surrogate for (.getBytes "hello") |
| 18:15 | dobry-den | ah, (byte-array (map byte "hello")) |
| 18:15 | technomancy | what's wrong with .getBytes? |
| 18:21 | dobry-den | nothing |
| 18:22 | magnars | Idiomatic way of doing this? Map a function over a seq, but instead of returning a seq of results, return a map of the original values -> results ? |
| 18:23 | technomancy | magnars: (into {} (map (juxt identity f) s)) |
| 18:23 | technomancy | or reduce |
| 18:23 | technomancy | juxt is cooler though |
| 18:23 | technomancy | clojurebot: juxt? |
| 18:23 | clojurebot | juxt is a little hard to grok but it's the best thing ever |
| 18:23 | magnars | that is cool. thanks! :) |
| 18:24 | technomancy | oh... (zipmap s (map f s)) is shorter |
| 18:24 | egghead | but then you don't get to use juxt |
| 18:24 | hyPiRion | technomancy: don't be silly, the juxt version must surely be more efficient. |
| 18:25 | magnars | the juxt version was too awesome to pass over |
| 18:25 | technomancy | hyPiRion: more effective at being cool |
| 18:25 | magnars | ^^ think I'll have to make a juxt for dash.el |
| 18:25 | hyPiRion | technomancy: yeah, I was not talking about any specific measure of efficient |
| 18:25 | technomancy | magnars: yes please! =D |
| 18:26 | seangrove | Hey guys, I think I may be onto something with my "greater hair theory" https://dl.dropboxusercontent.com/u/412963/greater_hair_theory.png |
| 18:26 | seangrove | The evidence is really starting to stack up |
| 18:27 | magnars | :D |
| 18:27 | seangrove | We thought it was the beard, turns out we were wrong |
| 18:27 | technomancy | nice |
| 18:32 | dnolen_ | haha |
| 18:37 | hyPiRion | I'm not sure whether the "greater hair theory" or the "facial hair theory" is correct, so I'm trying to get into both. |
| 18:37 | hyPiRion | better be safe than sorry |
| 18:40 | gt` | hi what is the quickest way to connect to ms sql database if i am using clojure on ubuntu |
| 18:50 | technomancy | any heroku users want to test out uberjar-based deploys before I merge it to mainline? |
| 18:51 | dobry-den | ,(map int (seq (String. (byte-array [(byte -1)])))) |
| 18:51 | clojurebot | (65533) |
| 18:52 | seangrove | hyPiRion: quite a wise approach, I'd say |
| 18:52 | dobry-den | How come it's 65533? |
| 18:53 | hiredman | characters are not bytes |
| 18:54 | dobry-den | rigiht, but why not 2^16? |
| 18:55 | hiredman | why should it be that? |
| 18:56 | dobry-den | oh, 65533 is a special "replacement character" |
| 18:59 | phildiaz | Hey, everyone. I come from Ruby programming for the web, and I'm just starting with Clojure. I seem to be having a problem that I suspect is really newb-ish, but I can't figure it out for the life of me. |
| 19:01 | phildiaz | I started my first lien project, and when I run my REPL server, everything works fine. I can use defn for methods and get normal resutls. |
| 19:01 | hiredman | functions |
| 19:01 | hiredman | defn defines functions |
| 19:02 | dobry-den | technically they are methods in java behind the scenes aren't they |
| 19:03 | phildiaz | Ah, yes. Thank you, I need to get my head into functional programming zone. |
| 19:03 | technomancy | dobry-den: each function becomes its own class |
| 19:03 | dobry-den | ah |
| 19:04 | dobry-den | sorry phildiaz. tried to get you a clutch technical-victory. |
| 19:04 | technomancy | iirc each arity is compiled into its own method |
| 19:04 | phildiaz | Haha, no problem. |
| 19:05 | phildiaz | The issue I'm having is switching namespaces. If I do "(in-ns 'first-try.core)" and attempt to run any sort of function, even "(+ 1 1)", I get a CompilerException. |
| 19:06 | technomancy | phildiaz: in-ns only works for namespaces that already exist; try using ns for new namespaces |
| 19:06 | hiredman | in-ns just changes what namespaces forms will be compiled in, it doesn't load any code |
| 19:06 | hiredman | if you have an existing namespace you'll want to require it |
| 19:07 | technomancy | (doto 'my.ns require in-ns) works too |
| 19:07 | hiredman | if you in-ns in to a not previously defined namespace you get an empty namespace |
| 19:08 | dobry-den | phildiaz: are you just trying to load your first-try.core code so you can test it in the repl? |
| 19:09 | phildiaz | Yes, I tried technomancy's suggestion, and it worked out. Thank you so much! |
| 19:09 | dobry-den | what editor/ide are you using? |
| 19:10 | phildiaz | Sublime Text 2. I installed the REPL package. |
| 19:12 | dobry-den | phildiaz: cool. see if there's a hotkey or something you can press that automatically loads your current file namespace into the repl for you. |
| 19:14 | phildiaz | Will do. Thank you all so much. I'm really excited to get started with this stuff. Like I said, I've been using Ruby for web stuff, and Clojure looks like a giant step up in development methodology. |
| 19:15 | phildiaz | Also, I'm a huge AngularJS fan, and this piqued my interest: http://keminglabs.com/blog/angular-cljs-mobile-weather-app/ |
| 19:26 | dobry-den | phildiaz: cool, i came from Ruby as well. |
| 19:27 | dobry-den | Sinatra is clunky and awkward after working with Compojure and company. |
| 19:27 | trinary | same, except I haven't really dug too far into clojure yet, too busy writing weird stuff in javascript. Need to swap to cljs. :) |
| 19:28 | dobry-den | Ruby of course is clunky as well. consider the clojure versions of animals.map(&:name) and animals.map { |a| a.name.upcase } |
| 19:29 | dobry-den | (map name animals), (map (comp upcase name) animals) |
| 19:32 | holo | anyone is able to use new relic deploying to heroku with an uberjar? for the life of me, I can't make this work |
| 19:37 | technomancy | holo: currently that can only be done by checking in the newrelic agent jar unfortunately |
| 19:37 | technomancy | I can add that before it gets merged though |
| 19:37 | technomancy | holo: the behaviour we discussed previously is now on the uberjar-name branch of the buildpack if you want to try it out |
| 19:38 | holo | technomancy, what do you mean by checking in the newrelic agent? |
| 19:38 | technomancy | holo: git add =( |
| 19:41 | holo | technomancy, oh.. I did add the .jar agent, and "pointed" to it in the environment JVM_OPTS. which behaviour? I don't remember |
| 19:41 | technomancy | holo: I mean checking for :uberjar-name instead of looking for lein in the procfile |
| 19:41 | technomancy | (from a few days ago) |
| 19:43 | holo | technomancy, hehe sure, I thought it was related to new relic. yes, I'm using that behaviour already, even though there is no need since I'm not using lein in Procfile |
| 19:44 | technomancy | cool |
| 19:44 | technomancy | yeah, sorry, the java-agent stuff still needs a bit more work in the buildpack |
| 19:48 | holo | technomancy, hey that's great, at least I know it's useless to spend more time with this stuff for the time being. thanks. where will you publish when it's solved in the buildpack? |
| 19:48 | holo | ok, just follow the buildpack commits, forgot about that one :) |
| 19:52 | holo | technomancy, a correction. I'm using :uberjar-name, which is the reason why I also don't need lein invocation anymore, because the naming is static |
| 19:54 | technomancy | holo: it will show up on the heroku changelog once it's merged as default behaviour, but keeping an eye on the github repo is your best bet until then |
| 19:54 | technomancy | happy to answer questions on irc too of course =) |
| 20:01 | holo | you're great. thanks. I try always not to abuse much of it. I imagine how busy you are |
| 20:02 | dnolen_ | my god, I love it! http://gist.github.com/swannodette/5888989 |
| 20:14 | technomancy | holo: to tell the truth, I can't really think of a good way to support this nicely |
| 20:14 | Sorella | Better than Microsoft, as far as consoles go |
| 20:15 | Sorella | Hm, wrong channel. |
| 20:18 | technomancy | the whole point of uberjar is "collapse the project and its dependencies down into one file" |
| 20:18 | technomancy | which doesn't work with java-agents at all; it has to be a separate file |
| 20:18 | holo | i see |
| 20:18 | technomancy | so you either have to shoehorn it into the uberjar task or provide an additional task to copy the agent jars into target/ or something |
| 20:25 | yogthos | technomancy: can we do another quick purge on clojars at some point? :) |
| 20:26 | technomancy | yogthos: yeah, for users of pre-2.2 lein? |
| 20:26 | technomancy | it's not a problem on the latest, right? |
| 20:26 | yogthos | technomancy: oh I haven't checked :) |
| 20:26 | yogthos | technomancy: if it's not then I wouldn't bother |
| 20:27 | technomancy | ok, cool |
| 20:27 | yogthos | technomancy: incentive for people to upgrade :) |
| 20:27 | yogthos | you did the magic to parse the versions out after all? :) |
| 20:27 | technomancy | yogthos: there's another magic way to specify "latest" without triggering that stupid aether bug |
| 20:28 | yogthos | oooh |
| 20:28 | yogthos | that is very awesome! |
| 20:28 | technomancy | you're probably the only person who is that excited about it, but yes; it's a good improvement =) |
| 20:29 | yogthos | lol I like to push out builds often :) |
| 20:56 | dnolen_ | I don't even ... https://gist.github.com/swannodette/5888989 |
| 21:55 | g06|in | why doesn't 'ctrl y' inside a 'lein repl' paste from clipboard? instead it pushes the REPL to background |
| 22:10 | mmarczyk | dnolen_: ping |
| 22:10 | dnolen_ | mmarczyk: pong! |
| 23:24 | technomancy | g06|in: that's a known bug; there's a thread on the clojure mailing list about it |
| 23:24 | g06|in | technomancy: thanks! |
| 23:25 | g06|in | technomancy: I also can't seem to access clojuredocs via lein repl -- that a bug too? |
| 23:26 | technomancy | g06|in: that's intentional; the clojuredocs client was causing a lot of dependency conflicts |
| 23:26 | technomancy | you can add it back in yourself, but I think we haven't documented that right yet |
| 23:26 | g06|in | ok |
| 23:27 | g06|in | technomancy: I was trying to learn clojure and the first thing I came across was the setup with lein and it mentioned a couple of examples including the one using clojure-docs; that's why I asked |
| 23:27 | technomancy | ah, yeah bummer |
| 23:27 | technomancy | it was a little-used feature that caused lots of headaches |
| 23:27 | technomancy | but we should document how to re-enable it |
| 23:28 | g06|in | technomancy: thanks! |
| 23:41 | bbloom | dnolen_: so what did you find out about large functions in JS… no big deal? |
| 23:59 | derek_c | Does Leiningen support all maven repos? |
