clojurians | clojure | your code seems fine to me | 2017-12-01T10:40:25.000305 | Guillermo |
clojurians | clojure | Not good for readily understandable code. :slightly_smiling_face: | 2017-12-01T10:40:43.000170 | Dirk |
clojurians | clojure | Seems fine to me too with update. | 2017-12-01T10:42:24.000560 | Johana |
clojurians | clojure | Maybe that’s the problem with Specter too. | 2017-12-01T10:42:44.000521 | Johana |
clojurians | clojure | Or Clojure. :stuck_out_tongue: | 2017-12-01T10:43:14.000349 | Johana |
clojurians | clojure | <@Altagracia> with specter: `(setval [:a ALL :deleteme] NONE data)` | 2017-12-01T10:50:59.000426 | Owen |
clojurians | clojure | Ah, <@Sonny> replied: it’s probably about holding the head | 2017-12-01T10:52:16.000475 | Johana |
clojurians | clojure | Anyone here familiar with a javalib which compresses animated gifs, similiar to what Guetzli does to jpgs? | 2017-12-01T11:10:46.000560 | Sherrie |
clojurians | clojure | (clojure libs are valid too, but we're more of a wrapping kinda people) | 2017-12-01T11:38:39.000329 | Sherrie |
clojurians | clojure | probably anything you find would be a wrapper. | 2017-12-01T11:40:20.000526 | Guillermo |
clojurians | clojure | I don't know of anything, but if there is a C library that does what you need, it's straightforward to wrap C, and pretty pleasant using JNR-FFI | 2017-12-01T11:40:55.000004 | Guillermo |
clojurians | clojure | you don't have to write any C glue manually | 2017-12-01T11:41:07.000553 | Guillermo |
clojurians | clojure | Name it | 2017-12-01T11:43:16.000851 | Sherrie |
clojurians | clojure | or simply avoiding calling first on anything for cases where that realizes things | 2017-12-01T11:53:33.000529 | Sonny |
clojurians | clojure | What do you do in clojure spec to generate sample `(gen/sample (s/gen ::foo))` with unique value like `code`. Do you make own function for code generation or is some simpler way? | 2017-12-01T12:15:30.000711 | Gladys |
clojurians | clojure | you can use `s/with-gen` to supply a custom generator when you define a spec | 2017-12-01T12:28:47.000764 | Sonny |
clojurians | clojure | or supply an override generator function when a spec is used in places like s/exercise, stest/instrument, etc | 2017-12-01T12:29:10.000257 | Sonny |
clojurians | clojure | yes, i was thinking about `s/with-gen`. Not sure what you mean by override generator. Probably i don’t know about something :slightly_smiling_face: | 2017-12-01T12:31:51.000273 | Gladys |
clojurians | clojure | functions like s/exercise take a map of spec name to generator functions that can be used to override the generator for a spec just in the context of that call | 2017-12-01T12:36:57.000234 | Sonny |
clojurians | clojure | oh i see some things changed in the doc from last time when i saw it, thx | 2017-12-01T12:38:47.000035 | Gladys |
clojurians | clojure | ```clojure
user=> (s/def ::i int?)
:user/i
user=> (s/exercise ::i)
([0 0] [-1 -1] [1 1] [-1 -1] [-6 -6] [-6 -6] [-4 -4] [2 2] [-2 -2] [-56 -56])
user=> (s/exercise ::i 10 {::i (fn [] (s/gen #{5 10}))})
([5 5] [5 5] [10 10] [5 5] [5 5] [10 10] [10 10] [5 5] [5 5] [5 5])``` | 2017-12-01T12:39:59.000433 | Sonny |
clojurians | clojure | the docs have been out of date for a very long time but I refreshed them last week | 2017-12-01T12:40:16.000427 | Sonny |
clojurians | clojure | In Stuart Halloway's talk Simplicity Ain't easy, at the end he mentioned that there is some interesting discussion about design foundations other than simplicity. I can't seem to find any more information on it. Does anybody know of any discussion on that? | 2017-12-01T15:15:38.000100 | Giovanni |
clojurians | clojure | <@Giovanni> the three ones from Rich and Stu are power, focus, and simplicity | 2017-12-01T16:04:44.000315 | Sonny |
clojurians | clojure | I think Stu has done talks on two of those (see also <https://www.youtube.com/watch?v=KZ8u_sWT9Ls> ) | 2017-12-01T16:05:39.000264 | Sonny |
clojurians | clojure | <@Sonny> Thanks much! | 2017-12-01T16:11:48.000226 | Giovanni |
clojurians | clojure | Maybe some day he will complete the trilogy and then we can get into the prequels | 2017-12-01T16:16:38.000164 | Sonny |
clojurians | clojure | just wait, he’ll use CGI to add realistic concrete inheritence when he re-releases the original | 2017-12-01T16:17:22.000217 | Margaret |
clojurians | clojure | #rich_shot_first | 2017-12-01T16:20:34.000468 | Sonny |
clojurians | clojure | If you are directly indexing `:a` you might not mind numerically indexing its array using medley's `dissoc-in`: | 2017-12-01T17:20:06.000234 | Branda |
clojurians | clojure | ```(let [d {:a [{:b 1 :deleteme "foo"}]}]
(dissoc-in d [:a 0 :deleteme]))``` | 2017-12-01T17:20:11.000250 | Branda |
clojurians | clojure | But if you have more than one element in `:a` I would just inline the lambda instead and use update as bork suggests:
```(let [d {:a [{:b 1 :deleteme "foo"}]}]
(update d :a (fn [m] (mapv #(dissoc % :deleteme) m))))``` | 2017-12-01T17:30:51.000022 | Branda |
clojurians | clojure | I'm getting an error when using clj with a deps.edn including a :local/root.
```{:deps {org.clojure/java.jdbc {:mvn/version "0.6.2-alpha2"}
oracle/driver {:local/root "./ojdbc7.jar"}}}
```
It says
```Error building classpath. Wrong number of args (4) passed to: local/eval398/fn--400``` | 2017-12-01T23:54:21.000016 | Wendi |
clojurians | clojure | Based on "Refer to a specific jar on disk" in <https://clojure.org/guides/deps_and_cli> | 2017-12-01T23:54:47.000029 | Wendi |
clojurians | clojure | I also tried full path etc. | 2017-12-01T23:55:04.000044 | Wendi |
clojurians | clojure | (Also interested in how to debug stuff like this.) | 2017-12-01T23:55:53.000047 | Wendi |
clojurians | clojure | is there a simple way to do a https supporting web server in java? it feels silly that my clojure code is all doing http/ws, then I am running some node.js wrapper to tunnel https -> http, wss -> ws | 2017-12-02T03:18:05.000040 | Berry |
clojurians | clojure | Answering my own question in part. `clj -Sverbose` will show details. In my case confirming my brew install wasn't the latest. (not a fix but still useful). | 2017-12-02T03:28:33.000060 | Wendi |
clojurians | clojure | <@Berry> have you seen this? <http://www.luminusweb.net/docs/deployment.md#setting_up_ssl> | 2017-12-02T04:28:13.000029 | Danyel |
clojurians | clojure | I personally just deploy to Elastic Beanstalk, which takes care of SSL and Nginx for me | 2017-12-02T04:29:24.000002 | Danyel |
clojurians | clojure | yeah, AWS makes SSL trivial | 2017-12-02T04:48:52.000041 | Berry |
clojurians | clojure | my situation is: I need this for local, with a self signed cert | 2017-12-02T04:49:03.000068 | Berry |
clojurians | clojure | some auth libs I'm talking to are unhappy unless the host url is ssl, thus, I need ssl even in my dev setup | 2017-12-02T04:49:23.000054 | Berry |
clojurians | clojure | I see, then yes I think Immutant is the way to go: <http://immutant.org/documentation/current/apidoc/guide-web.html#h3374> | 2017-12-02T05:17:12.000011 | Danyel |
clojurians | clojure | i'm a clojure newbie and am trying to learn channels and agents.
Did a small tutorial about them here: <https://joaoptrindade.com/tutorial-clojure-agents-and-channels>
anyone interested in giving some feedback? see if i understood the concept correctly | 2017-12-02T05:22:10.000032 | Tisha |
clojurians | clojure | Hi. what’s the equivalent in clojure for ```hash_hmac('sha512')``` | 2017-12-02T05:36:12.000090 | Tameka |
clojurians | clojure | what is the equivalent in java ? :stuck_out_tongue: | 2017-12-02T05:46:49.000068 | Marty |
clojurians | clojure | Based on that error, it’s probably a bug based on one of the recent refactors. I will take a look. Also btw, this stuff is good for <#C6QH853H8|tools-deps> | 2017-12-02T08:50:47.000115 | Sonny |
clojurians | clojure | yep, had some signature drift. will be fixed in next release. | 2017-12-02T09:01:38.000058 | Sonny |
clojurians | clojure | as a temp workaround, you can probably declare it in paths instead -
`:paths ["src" "ojdbc7.jar"]` | 2017-12-02T09:02:53.000007 | Sonny |
clojurians | clojure | that’s not what paths is for, but it should work | 2017-12-02T09:03:22.000039 | Sonny |
clojurians | clojure | buddy includes that sort of thing <https://funcool.github.io/buddy-core/latest/#hmac> | 2017-12-02T10:02:21.000107 | Leann |
clojurians | clojure | there are more reasons to use nginx as a reverse proxy - it has better security and more reliable security updates than most alternatives, and if set up properly can improve performance and balance your load for you | 2017-12-02T10:45:11.000039 | Margaret |
clojurians | clojure | as stupid as it sounds, neither performance nor load balancing matters
for production, I'm using AWS for SSL
this is literally for local, where there is just one user (me), and I need SSL because some auth libraries I'm playing with barf if my webpage isn't hosted in SSL | 2017-12-02T13:03:08.000057 | Berry |
clojurians | clojure | oh - aws might be using nginx for your ssl for all I know (I know that is how it works for our app at least) | 2017-12-02T13:06:20.000014 | Margaret |
clojurians | clojure | when creating a restful api using ring + compojure, do I have to specify `{:body ..}` for every single handler? Is it not possible to make this automatic | 2017-12-02T15:24:51.000031 | Tameka |
clojurians | clojure | ? | 2017-12-02T15:24:51.000124 | Tameka |
clojurians | clojure | this is what I mean:
```
(defn index-page [req]
{:body {:data [{:id 1
:name "Some name"}]}})
(defroutes app-routes
(GET "/" _ index-page))
``` | 2017-12-02T15:26:11.000100 | Tameka |
clojurians | clojure | Thanks. | 2017-12-02T17:23:22.000031 | Wendi |
clojurians | clojure | how can I make an http call in ring and return the result to the client? when I do this
```
(defn get-orders [req]
(let [{:keys [sig uri]} (api-signature :get-orders)]
(client/get uri
{:async? true}
(fn [response] {:body "something"})
(fn [exception] {:body "error"}))))
``` | 2017-12-02T17:49:22.000086 | Tameka |
clojurians | clojure | it gives me this error
``` No implementation of method: :render of protocol: #'compojure.response/Renderable found for class: org.apache.http.impl.nio.client.FutureWrapper
``` | 2017-12-02T17:49:46.000072 | Tameka |
clojurians | clojure | <@Tameka> you're making an async `get` call inside a _synchronous_ handler. | 2017-12-02T18:20:19.000061 | Daniell |
clojurians | clojure | You could use Ring's async handler machinery -- or force a dereference on the `get` call -- or just do a synchronous `get` instead. | 2017-12-02T18:21:15.000068 | Daniell |
clojurians | clojure | thanks <@Daniell>. Actually I removed `:async? true` along with callbacks and it works fine now | 2017-12-02T18:27:08.000023 | Tameka |
clojurians | clojure | I just don’t get what’s the point of async in here :smile: | 2017-12-02T18:28:12.000094 | Tameka |
clojurians | clojure | is it there just so it doesn’t block IO? | 2017-12-02T18:28:40.000054 | Tameka |
clojurians | clojure | If you were using Ring's async handlers, it would make sense to use the async version of `get` -- and, yes, async would not block while the HTTP call is processed. | 2017-12-02T18:31:50.000063 | Daniell |
clojurians | clojure | I’ve created a new project using `chestnut` template and when I do `lein install`, it throws this error:
```Cannot run program "sassc": error=2, No such file or directory```
once I remove this bit from my project.clj it works:
``` :sassc [{:src "src/scss/style.scss"
:output-to "resources/public/css/style.css"}]
:auto {"sassc" {:file-pattern #"\.(scss)$"
:paths ["src/scss"]}}
``` | 2017-12-03T04:43:34.000063 | Tameka |
clojurians | clojure | is there something wrong with `sassc`? | 2017-12-03T04:43:55.000052 | Tameka |
clojurians | clojure | `(reduce * (int-array [1 2 3 4]))` <-- why does this code work? what is causing the reduce to be able to handle what I believe to be a JVM object | 2017-12-03T05:44:36.000037 | Berry |
clojurians | clojure | <@Berry> It goes like this: reduce -> coll-reduce -> protocol on type "Object" -> seq the given array -> `ArraySeq_int` -> Faster internal reduce on it. | 2017-12-03T06:02:02.000058 | Randee |
clojurians | clojure | <@Berry> Actually, this is wrong: Check out:
```
(reduce (fn [_ _]
(try (throw (Exception.)) (catch Exception ex ex)))
0 (int-array [0 1]))
``` | 2017-12-03T06:09:24.000025 | Randee |
clojurians | clojure | It'd would use a faster internal reduce if you seq your array beforehand, it's more than 2x faster with `(reduce ... (seq (int-array ...))` | 2017-12-03T06:09:52.000016 | Randee |
clojurians | clojure | <@Randee> I don't understand what that snippet is supposed to show | 2017-12-03T06:26:49.000029 | Kareen |
clojurians | clojure | <@Kareen> It's just a little hack to see get the stacktrace so I could see how the reduce function is called. With `(seq (int-array ...)` it shows nicely it's called from `ArraySeq_int.reduce` | 2017-12-03T06:27:52.000008 | Randee |
clojurians | clojure | ah ok | 2017-12-03T06:28:09.000014 | Kareen |
clojurians | clojure | nice hack :) | 2017-12-03T06:28:27.000093 | Kareen |
clojurians | clojure | <@Kareen> Do you think `(reduce ... ... some-array)` should also end up in `ArraySeq_int.reduce`? I could create a ticket for it.. | 2017-12-03T06:29:59.000080 | Randee |
clojurians | clojure | sure | 2017-12-03T06:44:47.000059 | Kareen |
clojurians | clojure | has anyone ever had a problem with `clj-http` when using `:as :clojure`? i.e.
```(client/get "<http://example.com/foo.clj>" {:as :clojure})```
I’m getting the following in my browser
``` Invalid keyword: .``` | 2017-12-03T07:13:03.000074 | Tameka |
clojurians | clojure | and when adding ```[org.clojure/tools.reader "1.1.1"]``` to my deps, CIDER dumps the following
```

``` | 2017-12-03T07:13:50.000051 | Tameka |
clojurians | clojure | <@Tameka> The contents of foo.clj might be up for question | 2017-12-03T07:16:22.000050 | Jodie |
clojurians | clojure | if I do `:as :json` then it works fine | 2017-12-03T07:16:50.000050 | Tameka |
clojurians | clojure | could it be that clojure map just doesn’t like something in there? | 2017-12-03T07:17:12.000099 | Tameka |
clojurians | clojure | <@Tameka> but, valid clojure is not the same as valid json | 2017-12-03T07:17:28.000030 | Jodie |
clojurians | clojure | Are you requesting a clj file, or a json file? | 2017-12-03T07:17:41.000061 | Jodie |
clojurians | clojure | it’s a json response from a server | 2017-12-03T07:17:57.000033 | Tameka |
clojurians | clojure | I thought it would convert automatically, but I guess that’s the issue yes :slightly_smiling_face: | 2017-12-03T07:18:15.000057 | Tameka |
clojurians | clojure | `:as :clojure` is for taking a _clojure string_ and turning it into a data structure. | 2017-12-03T07:18:47.000008 | Jodie |
clojurians | clojure | `:as :json` takes a json string, and turns it into a data structure. | 2017-12-03T07:18:59.000011 | Jodie |
clojurians | clojure | ah gotcha. thanks! | 2017-12-03T07:19:11.000020 | Tameka |
clojurians | clojure | and I’m guessing there’s no way to convert json to clj map, right? | 2017-12-03T07:26:03.000073 | Tameka |
clojurians | clojure | Actually, there is…
<https://github.com/clojure/data.json> | 2017-12-03T07:27:32.000008 | Olen |
clojurians | clojure | <@Tameka> can you take a look at this. | 2017-12-03T07:27:52.000025 | Olen |
clojurians | clojure | <@Tameka> Does `:as :json` not do that for you already? | 2017-12-03T07:29:04.000059 | Jodie |
clojurians | clojure | doesn’t seem to be doing so. it returns json string when I do `(:body response)` | 2017-12-03T07:29:52.000090 | Tameka |
clojurians | clojure | <@Tameka> do you have a dependency on cheshire? | 2017-12-03T07:32:10.000070 | Jodie |
clojurians | clojure | as I read in `clj-http` docs, `:as :json` requires `cheshire` lib. and when I add that to my deps, I get
```
[[cheshire "5.8.0"]
[tigris "0.1.1"]
[com.fasterxml.jackson.core/jackson-core "2.9.0"]
[com.fasterxml.jackson.dataformat/jackson-dataformat-cbor "2.9.0"]

clojurians | clojure | and then the `clj-http` has that section for `jackson` thingy | 2017-12-03T07:32:39.000054 | Tameka |
