| 00:13 | jrajav | Anyone used Clojure with Google App Engine before? |
| 00:34 | hiredman | yes, a long time ago, at the time it worked sort of fine, these was (is?) a lein plugin |
| 00:55 | matsu | what's the best way to check if all values of a map are empty/nil? |
| 00:55 | matsu | so { :foo {} :bar nil } would be considered empty |
| 00:59 | matsu | using `vals` would work, but only on top level keys |
| 01:27 | rhg135 | (every? ... (vals m)) |
| 01:32 | matsu | That would work only on the top level keys of m, right? |
| 02:09 | renl | hi can i do the following (def a :a) (def b {:a 1 :b 2}) (b a) works but (b (symbol "a")) doesnt |
| 02:11 | renl | got disconnected not sure if my previous question went through re-posting it |
| 02:11 | renl | hi can i do the following (def a :a) (def b {:a 1 :b 2}) (b a) works but (b (symbol "a")) doesnt |
| 02:13 | ridcully_ | ,(symbol "a") |
| 02:14 | clojurebot | a |
| 02:14 | ridcully_ | ,(keyword "a") |
| 02:14 | clojurebot | :a |
| 02:14 | ridcully_ | ah didnt saw the first def... ignore me |
| 02:15 | renl | ah ok |
| 02:19 | ridcully_ | something like: (b @(resolve (symbol "a"))) maybe? |
| 02:19 | renl | oh yeah |
| 02:21 | renl | well my original problem is with java interop. if i do this (Color. com.badlogic.gdx.graphics.Color/CORAL) it works but (Color. @(-> "com.badlogic.gdx.graphics.Color/CORAL" symbol resolve) doesnt |
| 02:26 | ridcully_ | isnt that just Color/CORAL ? |
| 02:27 | ridcully_ | i'd not expect you need to look up symbols here? this is just java interop. if you had to find that by name, id rather expect that to find via reflection? |

| 02:49 | faxmodem | how do I change the log level in repl? is there a global way to do that? |

| 03:15 | AndreasO | How do I put an event listener on a canvas in seesaw? |
| 03:55 | TEttinger | ilevd: use ,() with the comma to eval, clojurebot sometimes evals random code-like messages for fun |
| 03:56 | TEttinger | ,(dotimes [i 10] (print "Hello" i)) |

| 04:27 | CStorm | when i just want a simple form method on my new compjure project i run into csrf-token problems |
| 04:28 | CStorm | do i have to implement ring-anti-forgery? just want to have a input box and a send button which then post to another approute i have |
| 04:29 | mavbozo | CStorm, yes. if you use default compojure setup, you have to take into account csrf protection |
| 04:31 | CStorm | i have the following: |
| 04:31 | CStorm | http://pastebin.com/FyYQ7dbT |
| 04:31 | CStorm | the route i outcommented if i call that i get a token, and i can set that and then curl post to the send– however i am not sure how i should do when i want a setup like there is now |
| 04:32 | CStorm | where i input something in the form, and send and it automatically handles the token. |
| 04:34 | CStorm | i guess the question is how i can incorporate it into the little test i have linked so i dont really have to think about it. |
| 04:35 | clgv | cfleming: ping |
| 04:36 | TEttinger | I would also ping cfleming |
| 04:36 | clgv | :P |
| 04:37 | mavbozo | CStorm, you can put <input type='hidden' name='__anti-forgery-token' value='*anti-forgery-token*'/> inside your <form> |
| 04:37 | clgv | cfleming: Cursive/IntelliJ offers the "Extend Selection" command - is there any command to extend the selections to the left or right "siblings" within an s-expression? |
| 04:37 | CStorm | let me try that mavbozo, thanks for helping me out |
| 04:38 | TEttinger | clgv, I've been hoping to be online when cfleming is for weeks now |
| 04:38 | clgv | TEttinger: oh ok, so he isnt around here as frequent as in the past... |
| 04:38 | mavbozo | CStorm, try that using browser first |
| 04:39 | clgv | $seen cfleming |
| 04:39 | TEttinger | maybe just time |
| 04:39 | TEttinger | no lazybot |
| 04:39 | clgv | :( |
| 04:39 | clgv | ;( |
| 04:39 | TEttinger | :( indeed |
| 04:39 | hyPiRion | lazybot has been dead for a long time =| |
| 04:39 | clgv | what happened? |
| 04:39 | TEttinger | it doesn't have reconnect code |
| 04:39 | TEttinger | so during stuff like DDoS hellstorms, it has no hope of staying online |
| 04:40 | clgv | well that could be fixed easily, right? |
| 04:40 | TEttinger | indeed, I've hacked a fix into my lazybot that uses crappy windows stuff |
| 04:40 | clgv | why windows? |
| 04:40 | clgv | ,(inc 1) |
| 04:40 | clojurebot | 2 |
| 04:40 | clgv | but clojurebot is a tougher guy? :P |
| 04:41 | TEttinger | (basically relaunches the app from the command line when there hasn't been a message in a while) |
| 04:41 | TEttinger | (including ping) |
| 04:42 | CStorm | hm, mavbozo still gives me "Invalid anti-forgery token" |
| 04:43 | TEttinger | maybe you need to forge an anti-forgery token in the smithing forge |
| 04:43 | CStorm | haha |
| 04:46 | hyPiRion | CStorm: I have no idea what mavbozo is, but I've seen that error message related to https://github.com/ring-clojure/ring-anti-forgery |
| 04:46 | mavbozo | mavbozo, that's harsh |
| 04:47 | CStorm | i have ring-anti-forgery added |
| 04:47 | CStorm | and basicly the whole project is this: http://pastebin.com/JNN2DQc6 |
| 04:47 | CStorm | but this still gives me invalid token |
| 04:48 | hyPiRion | mavbozo: Oh sorry :x I thought the sentence "mavbozo still gives me "Invalid anti-forgery token"" meant that some project named mavbozo gave that error message |
| 04:48 | mavbozo | CStorm, add another route (GET "/csrf-token" [] (generate-string {:csrf-token *anti-forgery-token*})) |
| 04:48 | CStorm | yes? |
| 04:48 | mavbozo | and then check "/" source in the browserand "/csrf-token" |
| 04:49 | CStorm | ok |
| 04:49 | mavbozo | see if anti-forgery token in both pages are the same |
| 04:49 | mavbozo | hyPiRion, :) |
| 04:50 | clgv | TEttinger: you can only forge those in Mount Doom ;) |
| 04:51 | CStorm | mavbozo: seems like its not added to the request header, and i get a token when i visit csrf-token as expected |
| 04:51 | CStorm | the request headers for / looks like this: |
| 04:52 | CStorm | https://usercontent.irccloud-cdn.com/file/mMLO3Mva/Screen%20Shot%202016-03-11%20at%2010.51.32.png |
| 04:56 | mavbozo | CStorm, what's the return body of /csrf-token ? |
| 04:56 | CStorm | {"csrf-token":"yACvl/Y5lytBFK/VIPa29pVsxsLXhrbDcbSuaCTSXQLknlHQWuFyvtcca9lhrN9uxkOv5Q8Vc4CQEEli"} |
| 04:58 | mavbozo | CStorm, something's wrong with your form string in "/" route. try this one https://www.refheap.com/115804 |
| 04:58 | CStorm | will try that, hang on |
| 04:59 | mavbozo | when you view the page source of "/" in your browser, the value of __anti-forgery-token must be same as that is returned from "/csrf-token" route |
| 05:00 | CStorm | now its the same! |
| 05:00 | CStorm | hang on ill try to see if it works. |
| 05:01 | CStorm | now it works, mavbozo. |
| 05:02 | mavbozo | CStorm, great! :) |
| 05:02 | CStorm | phew, thanks for taking your time. |
| 05:02 | CStorm | really appreciate it |
| 05:04 | mavbozo | CStorm, you're welcome |
| 05:04 | CStorm | and happy friday :) |

| 06:00 | lizzin | ridcully_ TEttinger got it. thanks |
| 06:01 | TEttinger | cool |
| 06:02 | lizzin | which http client shoudl i use? http-kit? |
| 06:03 | TEttinger | no idea what's the best |
| 06:03 | TEttinger | stick around and someone may come online soon-ish |
| 06:03 | TEttinger | 6 AM east coast time |
| 06:03 | lizzin | ok |
| 06:04 | lizzin | i should be sleeping myself |
| 06:04 | ridcully_ | lizzin: i use clj-http for fooling around with apis all the time |
| 06:04 | lizzin | <-- east coaster |
| 06:04 | TEttinger | woo ridcully_ to the rescue |
| 06:04 | MJB47 | i use http-kit client a fair bit |
| 06:04 | MJB47 | mostly because it has good support for websockets as well |
| 06:05 | MJB47 | which comes in handy sometimes |
| 06:05 | MJB47 | never had a problem with it |
| 06:05 | TEttinger | yay http people... I'm so drowsy |
| 06:05 | TEttinger | yer the best #clojure |
| 06:06 | lizzin | if i want to download a jpg and then write it to my desktop, i can just do a http get as a stream and then use output-stream to write it to disk right? |
| 06:06 | ridcully_ | i'd assume that http-kit might make the better component for a library or within your application |
| 06:06 | ridcully_ | clj-http is dead simple for the repl |
| 06:08 | ridcully_ | and aleph also has a client, right? or is it just using something else? |
| 06:09 | lizzin | https://gist.github.com/anonymous/1bdb195f4128328159b9 |
| 06:14 | mavbozo | aleph also has http client |
| 06:31 | mavbozo | lizzin, write method on wrtr object can not accept string |
| 06:36 | mavbozo | lizzin, i assume (:body @resp) return string |
| 06:37 | lizzin | mavbozo: i thought i had taken care of this with the '{:as stream}' |
| 06:43 | mavbozo | lizzin, sorry, I misread. Yeah, {:as :stream} returns the :body from response as java.io.InputStream but wrtr.write only accepts byte[] or byte |
| 06:43 | ilevd | ,(doseq [i ["nice", "cool", "beatiful"]] (print "Clojure is " i "! ")) |
| 06:43 | clojurebot | Clojure is nice ! Clojure is cool ! Clojure is beatiful ! |
| 06:48 | lizzin | mavbozo: where is that mentioned? im not seeing it here: https://clojuredocs.org/clojure.java.io/output-stream |
| 06:49 | lizzin | i believe you, just wondering which docs i should be reading |
| 06:52 | mavbozo | io/output-stream returns java.io.BufferedOutputStream http://docs.oracle.com/javase/7/docs/api/java/io/BufferedOutputStream.html |
| 06:52 | lizzin | yep, just stumbled on that |
| 06:52 | lizzin | thanks |
| 06:53 | lizzin | also, changing stream to 'byte-array' fixed things as expected |
| 06:53 | lizzin | mavbozo: happen to know of any good docs that cover the diff between byte stream and byte arrays? |

| 08:58 | ilevd | Yeah, he is a good interlocutor |
| 09:07 | ridcully_ | if only i could remember the syntax to teach clojurebot facts |
| 09:36 | X-warrior | hey guys I'm new to clojure and I'm not sure if my code is readable and the right way of doing things on clojure. Could anyone review it? https://bitbucket.org/matheusbrat/clojure |
| 09:41 | TimMc | X-warrior: I only have time for a quick glance... but the indentation is pretty wild, what are you using for an editor? |
| 09:41 | MJB47 | X-warrior: your indentation is pretty funky, and im not sure if thats the way i would do the node stuff |
| 09:41 | MJB47 | but otherwise it looks fine |
| 09:41 | TimMc | ~use |
| 09:41 | clojurebot | Only use :use with :only. |
| 09:41 | X-warrior | TimMc: sublime |
| 09:42 | xemdetia | yeah that indent is all over the place :( |
| 09:42 | TimMc | See if it has a clojure formatting mode or plugin or something. |
| 09:42 | TimMc | X-warrior: Also you'll want to use :use *very* sparingly. |
| 09:43 | TimMc | Those (use ...) blocks should be requires (with :as) and should be moved up into the ns block. |
| 09:43 | MJB47 | sublime does |
| 09:43 | MJB47 | i used to use it |
| 09:43 | MJB47 | its acceptable |
| 09:43 | MJB47 | X-warrior: https://github.com/bbatsov/clojure-style-guide#source-code-layout--organization |
| 09:43 | MJB47 | this might be useful |
| 09:44 | TimMc | For instance, when I see (.printTree tree 0) at the bottom of core.clj, what does tree refer to? It's impossible to tell without looking through the other namespaces. You should be able to look at code and see where a var came from without going to another file. |
| 09:45 | X-warrior | TimMc: so it would be better to use the namespace instead of :refs :all so I would need to specify tree/tree |
| 09:46 | X-warrior | MJB47: I will take a look |
| 09:46 | X-warrior | MJB47: did you use any plugin with sublime? or just regular sublime? |
| 09:46 | MJB47 | i used a few things |
| 09:46 | MJB47 | let me see if i can find |
| 09:47 | MJB47 | hmm, seems i actually on used LispIndent |
| 09:47 | MJB47 | and sublimeREPL (which tbh is quite bad) |
| 09:48 | TimMc | X-warrior: That's right, (:require [clojure.java.io :as io]) and then you can do io/reader |
| 09:49 | TimMc | If there's something you use a whole lot of and it's a real pain to have a namespace prefix, you can :refer [foo bar baz] as needed. |
| 09:49 | TimMc | X-warrior: The two let blocks in parse-line can be combined into one, since let evaluates and binds sequentially. |
| 09:50 | TimMc | You could even do (let [[customer invited] (str/split line #" ")] ...) -- destructuring is great |
| 09:59 | X-warrior | TimMc: what do you mean by destructuring? using a single line? x) |
| 10:00 | X-warrior | MJB47: thanks! I will take a look at lispindent |
| 10:03 | TimMc | X-warrior: Destructuring is a syntax for taking apart data structures: http://clojure.org/reference/special_forms#binding-forms |
| 10:03 | TimMc | so you don't have to say first, second |
| 10:05 | ridcully_ | ,(let [[a b] [1 2]] (println a b)) |
| 10:05 | X-warrior | Oh, now I see it |
| 10:05 | clojurebot | 1 2\n |
| 10:09 | X-warrior | I should change my indentation to two spaces too |
| 10:10 | X-warrior | going to eat, 5 minutes, thanks TimMc |
| 10:12 | timvisher | is it possible to create an uberjar without a main class? |
| 10:12 | timvisher | via lein |
| 10:13 | justin_smith | timvisher: sure, but you could just make clojure.main your main class too |
| 10:15 | timvisher | justin_smith: how would you do it? if we don't specify :main and have no `:gen-class`es in the code base clojure.main seems to be set as main by default |
| 10:15 | justin_smith | timvisher: hmm, maybe that happened and I was OK with that - what specific reason do you have to not have a main class at all? |
| 10:15 | timvisher | apparently hadoop runs the main if it exists |
| 10:16 | justin_smith | that's so dumb |
| 10:16 | timvisher | which is 1000% :) |
| 10:16 | timvisher | i mean in theory i could edit the jar afterwards |
| 10:17 | timvisher | i'm not sure how difficult that would be but i imagine it would be removing a line or two from the properties file or something |
| 10:20 | TimMc | timvisher: It's the manifest.mf, I think... |
| 10:21 | TimMc | Try :main nil and see what happens. |
| 10:21 | timvisher | TimMc: yeah that's what hyPiRion is suggesting |
| 10:22 | TimMc | Worst case you can write a script to extract the manifest, filter it with grep, and put it back in. |
| 10:24 | timvisher | TimMc: right. not a huge deal |
| 10:24 | timvisher | the class file can stay in there too as long as the manifest isn't pointing to it |
| 10:26 | hyPiRion | It's annoying to do it manually though |

| 11:53 | OscarZ | hi.. what do you recommend for logging? |
| 11:55 | ilevd | I want to know an answer too. I usually use print |
| 11:56 | justin_smith | ,((constantly "ed")) |
| 11:57 | clojurebot | "ed" |
| 11:57 | OscarZ | yeah same.. i dont need anything fancy.. maybe log into a file and stdout |
| 11:58 | ilevd | I think maybe some wrapper around log4j |
| 11:59 | OscarZ | hmm.. maybe ill try this: http://www.bahmanm.com/blogs/how-to-add-logging-to-a-clojure-project |
| 12:11 | bacon1989 | i haven't used logging in any of my clojure projects, but if I did |
| 12:12 | bacon1989 | i'd use some sort of log4j wrapper |
| 12:12 | bacon1989 | first thing I found: https://github.com/clojure/tools.logging |
| 12:13 | bacon1989 | which works with log4j |
| 12:13 | ilevd | It's the same |
| 12:14 | ilevd | So it's the answer |

| 12:59 | parsecChar | I'm writing a "strict Haskell" -> JS compiler. Initially, I was targetting JS. But then I realized: I have to deal with persistent data structures, tail call optimization, + not having "everything is an expression." I'm now considering targeting "strict Haskell" ->CLJS, and using cljs for cljs -> js. |
| 12:59 | parsecChar | Are there any things I should keep in mind concerning cljs (or a different suggested target language?) |
| 13:02 | justin_smith | parsecChar: you should check out elm, elm is pretty awesome and it targets js |
| 13:02 | justin_smith | and is very haskell-like |
| 13:02 | parsecChar | yeah, but it lacks things like typeclasses |
| 13:02 | parsecChar | I'm currently compiling from GHC/Core |
| 13:02 | ridcully_ | the idea that some haskell code gets transpiled to clojure would give some ppl a heart attack? |
| 13:02 | parsecChar | i.e. you can write literla Haskell code, type check it with ghc, and then get a strictly interpreted it as js |
| 13:03 | justin_smith | oh, OK |
| 13:03 | parsecChar | if you take haskell and strip out types, you basically have cllojure left over |
| 13:03 | justin_smith | depends if you count "strict tracking of side-effects" as a subset of types |
| 13:04 | justin_smith | because we don't track side effects for the most part |
| 13:04 | parsecChar | justin_smith: yeah, but my original code is in haskell |
| 13:04 | parsecChar | so haskell enforces the 'no side effect,s except in monads' |
| 13:05 | parsecChar | then the 'pure' code gets compiled to cljs |
| 13:05 | parsecChar | what's the quickest way to get started with clojure on ubuntu |
| 13:05 | parsecChar | I haven't used clojure in years |
| 13:05 | justin_smith | parsecChar: all you need is the leiningen script and a jvm newer than 1.5 |
| 13:06 | justin_smith | an editor that doesn't suck is a nice to have, but those are strictly sufficient |
| 13:06 | parsecChar | do I use openjdk or the sun/oracle licensed one? |
| 13:06 | justin_smith | doesn't matter |
| 13:06 | justin_smith | newer than 1.5 is enough |
| 13:08 | parsecChar | got openjdk 8 |
| 13:08 | parsecChar | got lein script |
| 13:09 | parsecChar | got lein-2.6.1-stanealone.jar |
| 13:09 | justin_smith | well the lein script takes care of that |
| 13:09 | parsecChar | yeah, running ./lein did the weget |
| 13:09 | justin_smith | right, right |
| 13:09 | parsecChar | reading https://github.com/clojure/clojurescript/wiki/Quick-Start |
| 13:09 | justin_smith | then you can use lein new, or use lein to run an existing cloned project, or whatever |
| 13:09 | parsecChar | but is ther a way to pull cljs with lein instead ? |
| 13:11 | justin_smith | parsecChar: that comes later in the Quick-Start |
| 13:11 | justin_smith | I'm actually a fan of how the Quick-Start starts with no tooling before introducing the magic |
| 13:12 | parsecChar | I've used lein before |
| 13:12 | parsecChar | I'm familiar with clojure/clojurecript, just not ofr the past 2-3 years |
| 13:13 | parsecChar | https://github.com/swannodette/mies I like more |
| 13:13 | parsecChar | full of magic |
| 13:13 | parsecChar | jumps me right into what I need |
| 13:14 | justin_smith | I like that the Quick-Start starts without lein not because there's any problem with lein, but because I think it's good to know how each part works (and is liable to break) before jumping into the thing that abstracts all of them. If every lein plugin were a reliable abstraction I would revisit that opinion, but as it is you might as well learn because the abstraction is going to break. |
| 13:15 | parsecChar | wait until I have to write job postings for hiring people |
| 13:15 | parsecChar | looking for people .. who knows Haskell ... and clojure .... and okay with using our custom in house Haskell -> CLJS compiler |
| 13:15 | justin_smith | haha |
| 13:16 | ridcully_ | having a heartackack ;) |
| 13:16 | justin_smith | "hey, that's me! (kinda)" |
| 13:16 | zerokarmaleft | parsecChar: what about purescript? |
| 13:16 | parsecChar | I almost used purescript |
| 13:17 | parsecChar | but I found the tooling to be lacking compared to haskell |
| 13:17 | parsecChar | i.e. ghci / reload, vim-haskell-now |
| 13:18 | zerokarmaleft | `pulp psci` gives a decent repl reloaded experience |
| 13:18 | parsecChar | I found it very slow |
| 13:18 | zerokarmaleft | but I agree, haskell tooling is much further along |
| 13:18 | parsecChar | to the point where I liked ghcjs/haste more |

| 13:28 | ben_vulpes | most of the jdbc functions take a db spec, how would i best programatically /create/ a database in postgres from jdbc? |
| 13:29 | ben_vulpes | if shelling out to say psql is the thing to do, i can also do that i suppose but i'd rather not |
| 13:29 | ridcully_ | there is a slight chance you simply can. if you have no "dba" user to create one in the first place, you simply can't |
| 13:33 | ben_vulpes | (jdbc/do-commands "postgresql://wherever:port/new-db" "create database new-db") doesn't seem like it'd work, as new-db wouldn't exist... |
| 13:33 | ben_vulpes | mnope |
| 13:34 | justin_smith | wouldn't you have to do that with postgres as your db? |
| 13:35 | ben_vulpes | justin_smith: huh |
| 13:35 | justin_smith | ben_vulpes: to run that command, I would run "psql postgres" first, to start with the postgres db opened |
| 13:35 | ridcully_ | you can not connect to X to create database X |
| 13:36 | justin_smith | right, so you connect to the db called "postgres" if you have the perms to create a db |
| 13:37 | ben_vulpes | gotcha |
| 13:37 | ben_vulpes | ridcully_: myeah, suspected and confirmed. |
| 13:41 | freakcoder | some one use clojure to do statistical work? has some advantage to use it instead R? |
| 13:43 | justin_smith | freakcoder: for the small amount I've played with statistical stuff (our app does some statistical stuff, but I am not stats expert), clojure is much better than R performance wise, but the features are not nearly as friendly, even with the dedicated stats libraries. |
| 13:45 | freakcoder | I get it, maybe R is not a viable solution for production |
| 13:45 | justin_smith | freakcoder: for us, definitely not |
| 13:46 | justin_smith | but it's much easier for the "see what we can do with data" exploratory stage |
| 13:46 | justin_smith | even if it's not what backs the production api endpoint |
| 13:47 | freakcoder | but for research I think clojure can't beat it up yet |
| 13:48 | justin_smith | freakcoder: not until some stats genius implements a huge library in clj :) |
| 13:55 | ridcully_ | i cargoculted both ggplot2 and c3 in cljs... and i am not the wiser |
| 13:59 | kwladyka | Do you use Clojure .NET? How is it work in practice? |
| 14:00 | justin_smith | kwladyka: it is not as extensively supported, but last I played with it it just worked |
| 14:02 | kwladyka | justin_smith Is it possible to write integration for apps in .NET in clear Java (Clokure) without .NET? For example ERP systems? I am not sure how is it work. |
| 14:03 | kwladyka | i know it is not clear Clojure qestion, but maybe you know :) |
| 14:03 | justin_smith | kwladyka: I have no idea, I used clj-clr without java at all, using clr to compile the code and generating clr output |
| 14:03 | justin_smith | unlike cljs, clj-clr doesn't use java for compiling |
| 14:04 | kwladyka | justin_smith true. Just i want to know if i want write integration for app workking on .NET i have to use .NET or i don't have to.... |
| 14:05 | justin_smith | I think if you want something your .NET stuff can load as a library, you need to use the clj-clr compiler, the clojure compiler won't help |
| 14:05 | justin_smith | unless there is a bridge from clr to jvm I don't know about |
| 14:06 | kwladyka | justin_smith yeah it is not easy knowledge to get when i don't have any idea about .NET :) |
| 14:07 | kwladyka | hmm but i know one person who maybe know the answer... |
| 15:08 | kwladyka | Ok i know the answer: it is possible, but not worth if i want use complex API, because problems will appear. |
| 15:08 | kwladyka | So i will try Clojure .NET directly |
| 16:34 | X-warrior | TimMc, I changed that code, using destructuring, changing use for require with :as, fixing indentation (using 2 spaces) |
| 16:34 | X-warrior | :D |
| 16:35 | TimMc | great! |
| 16:41 | X-warrior | TimMc, could u take a final look? to check if I miss any of your points? |
| 16:41 | X-warrior | sorry if i'm being too baggy |
| 16:46 | TimMc | Busy now, sorry. |
| 16:47 | justin_smith | timvisher: does :main nil work? |
| 17:26 | ben_vulpes | how do i get exceptions thrown as a result of poking a ring app from, say, curl, to show up in cider? |
| 17:28 | justin_smith | I think you'd need a custom exception logging middleware. Also, have you checked the process buffer? I've mentioned the fact that many messages end up in the process buffer instead of the repl and bbatsov said this wasn't a bug, it was expected. |
| 17:28 | ben_vulpes | yeah, i've been checking the repl_server buffer |
| 17:29 | justin_smith | are you using jack-in or connect? |
| 17:30 | ben_vulpes | wrap-stacktrace is what i want, i believe. |
| 17:30 | ben_vulpes | justin_smith: jack-in |
| 17:31 | justin_smith | if you are fine with checking the process buffer, wrap-stacktrace should suffice yeah |
| 17:40 | ben_vulpes | hrm, wrap-stacktrace doesn't seem to be doing what i want either. |
| 17:41 | justin_smith | ben_vulpes: all you really need is a middleware that wraps all your other middleware and the handler, and prints stack traces to the right value for *out*, right? |
| 17:41 | justin_smith | that sounds like 3 lines of code to me (maybe with the addition of something that lets you manually mutate it's value of *out*) |
| 17:41 | ben_vulpes | myup |
| 18:41 | devn | Is it alright if I define defrecords inside of a toplevel defonce? |

| 22:20 | sdegutis | ,(re-seq #"[(\d\.)(?:,)]+" "$1,020.42") |
| 22:20 | sdegutis | I'm confused. |

| 22:25 | sdegutis | Oh this is fun. Check this out. |
| 22:25 | sdegutis | ,(int (* 100 (Float. 20.32))) |
| 22:25 | clojurebot | 2031 |
| 22:26 | amalloy | sdegutis: you know parens aren't metacharacters inside a character class? |
| 22:26 | sdegutis | amalloy: I do now. |
| 22:28 | amalloy | speaking of character classes, /[][]/ is a regex that perl accepts but java doesn't (it should, as far as i can understand PCRE) |
| 22:28 | devn | amalloy: I was worried that re-evaluating might be a problem. I seem to recall a problem with defining records inside of function definitions |
| 22:29 | devn | If I had a function (defn make-records [] (doseq [[rec-name arglist] '{A [b] C [d]}] (eval `(defrecord ~rec-name ~arglist)))) which I called more than once, would I run into trouble? |
| 22:33 | amalloy | do you really want to redefine your records at runtime? |
| 22:33 | amalloy | (correct answer: no) |
| 22:36 | TEttinger | ,(re-seq #"(?:(\d\.)|(?:,))+" "$1,020.42") |
| 22:36 | clojurebot | (["," nil] ["0." "0."]) |
| 22:37 | TEttinger | ugh |
| 22:45 | devn | amalloy: so, could you help me out here then? |
| 22:46 | devn | what is the right way to do this sort of thing? |
| 22:46 | amalloy | if you just want to define a bunch of related records, you can write a macro to do it (although it's a bit weird to define a bunch of related records to begin with) |
| 22:47 | amalloy | if you want to do any of the other stuff you've been talking about, you probably shouldn't, but it's hard to be sure since you're talking about techniques instead of goals |
| 22:49 | devn | amalloy: i have a lot of record types, and they are born from a lot of different sources. I have a map which contains the desired name of the record, with the set of fields it needs to be defined with |
| 22:49 | amalloy | why do you have a lot of record types? |
| 22:49 | devn | rules engine |
| 22:50 | amalloy | what does that have to do with anything? why can't these just be maps? |
| 22:50 | TEttinger | sdegutis: |
| 22:50 | TEttinger | ,(apply str (remove nil? (map second (re-seq #"(?:([\d\.])|(?:,))+?" "$1,020.42")))) |
| 22:50 | clojurebot | "1020.42" |
| 22:50 | sdegutis | Thanks! |
| 22:50 | sdegutis | That's similar to what I ended up with. |
| 22:50 | TEttinger | cool! |
| 22:51 | sdegutis | Okay, our cart looks way better now. Woo! |
| 22:51 | TEttinger | it's a weird thing that I can't think of a straightforward way to do it with just regexes |
| 22:51 | devn | amalloy: I _can_ use maps with clara, but my understanding (and please forgive me, but i must admit I have not measured this yet) is that maps will wind up being considerably slower |
| 22:51 | amalloy | if you haven't measured, use maps |
| 22:52 | amalloy | you can always replace them later, without breaking any kind of api compatibility |
| 22:52 | devn | heh, well that's sort of the thing |
| 22:52 | devn | it's sort of the other way around |
| 22:52 | devn | there are many records that already exist |
| 22:52 | devn | i am into the idea of switching to maps, but it will require a lot of rework |
| 22:56 | TimMc | TEttinger: Whoa, didn't know you could use \d inside a character class... |
| 22:56 | TEttinger | heh, neat trick :D |
| 22:56 | TEttinger | wait wait it gets better! |

| 23:00 | TEttinger | \pN is usually just a fancy version of \d |
| 23:00 | TEttinger | but it also matches things like circled numbers |
| 23:00 | TimMc | Yeah, that earlier expression could at *least* be reduced to #"[\d\.,]+", pretty sure |
| 23:01 | TEttinger | no |
| 23:01 | TEttinger | it needed to not match commas |
| 23:01 | devn | amalloy: so, you mentioned wrapping it with a macro. what are you suggesting? |
| 23:02 | TimMc | TEttinger: I see, only the [\d\.] was captured. |
| 23:02 | TimMc | then why even mention commas? |
| 23:03 | TimMc | ,(apply str (remove nil? (map second (re-seq #"(?:([\d\.]))+?" "$1,020.42")))) |
| 23:03 | clojurebot | "1020.42" |
| 23:03 | TEttinger | good point, TimMc |
| 23:03 | TEttinger | ,(clojure.string/replace "$1,0໕0.42" #"\p{Nd}" #(Integer/parseInt % 10)) |
| 23:03 | clojurebot | #error {\n :cause "java.lang.Integer cannot be cast to java.lang.String"\n :via\n [{:type java.lang.ClassCastException\n :message "java.lang.Integer cannot be cast to java.lang.String"\n :at [clojure.string$replace_by invokeStatic "string.clj" 69]}]\n :trace\n [[clojure.string$replace_by invokeStatic "string.clj" 69]\n [clojure.string$replace invokeStatic "string.clj" 106]\n [clojure.string$... |
| 23:04 | TEttinger | aw |
| 23:04 | TimMc | ,(apply str (re-seq #"[\d\.]+" "$1,020.42")) |
| 23:04 | clojurebot | "1020.42" |
| 23:04 | TEttinger | ,(clojure.string/replace "$1,0໕0.42" #"\p{Nd}" #(str (Integer/parseInt % 10))) |
| 23:04 | clojurebot | "$1,050.42" |
| 23:04 | TEttinger | that's the Lao digit 5 in there |
| 23:04 | TimMc | I usually use Devanagari. :-) |
| 23:05 | devn | amalloy: does it make any difference if I told you that all of these record definitions are of the form: (defrecord A [a b c]) with nothing else to them? |
| 23:05 | amalloy | ,(.parse (java.text.NumberFormat/getCurrencyInstance) "$1,0໕0.42") |
| 23:05 | clojurebot | 1050.42 |
| 23:05 | TEttinger | ,(clojure.string/replace "$६६६,0໕0.42" #"\p{Nd}" #(str (Integer/parseInt % 10))) |
| 23:05 | clojurebot | "$666,050.42" |
| 23:05 | TEttinger | nice amalloy |
| 23:05 | TimMc | heh |
| 23:05 | amalloy | i didn't actually notice the absurd 5 character |
| 23:05 | TEttinger | ha wow |
| 23:05 | TimMc | "absurd" |
| 23:05 | amalloy | the point is just that regexes are the wrong tool for parsing currency |
| 23:06 | TEttinger | you showed that well, yep |
| 23:06 | amalloy | they work fine, but... |
| 23:06 | amalloy | the currency parser understands locales, too, so you can read euros or whatever |
| 23:07 | TEttinger | amalloy: it's only absurd until you go down the river to find technomancy and find he's started a jungle cult of Racket in Laos |
| 23:07 | TimMc | or handle commas vs. periods |
| 23:08 | TEttinger | "Java 9 has been delayed to 2017? the horror... the horror..." |
| 23:18 | devn | heh, no dice eh? |
| 23:19 | devn | Is it as simple as wrapping a doseq in a defmacro, and dropping `(defrecord ~name ~arglist) in there? |
| 23:21 | devn | err, with an eval wrapper, that is |
