clojurians | clojure | <@Herlinda>: maybe
```
(defmacro qkw [kw]
`(keyword (str (namespace ::foo))
(str (name ~kw))))
``` | 2017-11-14T13:52:34.000832 | Berry |
clojurians | clojure | Is there any good way of creating an anonymous function which doesn't accept any arguments? I need to be able to create them nested.
```
#(function/one :alpha (partial function/two :bravo))
```
Using partial with full arguments works, but it doesn't feel right. | 2017-11-14T14:01:19.000678 | Earlie |
clojurians | clojure | <@Earlie>, you can’t nest `#(...)` anonymous functions, but you can nest the `(fn [] ...)` form | 2017-11-14T14:05:22.000119 | Jonas |
clojurians | clojure | Yeah, I know I can just nest fn calls. Was just curious if there was a core function for this type of thing. | 2017-11-14T14:06:22.000784 | Earlie |
clojurians | clojure | so either `(fn [] (function/one :alpha #(function/two :bravo))` or `(fn [] (function/one :alpha (fn [] (function/two :bravo)))` | 2017-11-14T14:06:23.000487 | Jonas |
clojurians | clojure | (A core function that allowed creating nested thunks) | 2017-11-14T14:06:51.000450 | Earlie |
clojurians | clojure | <@Berry> doesn't seem to work at the repl for me | 2017-11-14T14:06:54.000017 | Herlinda |
clojurians | clojure | <#C055AMK5Y|clojure-brasil> | 2017-11-14T14:17:25.000177 | Natosha |
clojurians | clojure | <@Berry> I'm not the best at writing macros and especially calling them from cljs namespaces, but I think you might be on the right track | 2017-11-14T14:20:26.000342 | Herlinda |
clojurians | clojure | I pasted your macro into a clj file and then called `(require-macros '[my-ns :refer [qkw]])` at the figwheel repl and it but when I call `(qkw :foo)` I get `:my-ns/foo` | 2017-11-14T14:23:01.000743 | Herlinda |
clojurians | clojure | so even with the macro it is still giving you the ns where it is defined and not where it's called. I'm not the best at writing macros so maybe it just needs to be tweeked | 2017-11-14T14:23:49.000299 | Herlinda |
clojurians | clojure | hey guys, I'm dealing with this strange issue -- when i call `(keys my-map)` the key `:example-key` is included in the results | 2017-11-14T15:39:04.000322 | Kathie |
clojurians | clojure | however, when i log `(:example-key my-map)` i get nil | 2017-11-14T15:39:42.000621 | Kathie |
clojurians | clojure | and when i print out `my-map` the key is nowhere to be found | 2017-11-14T15:40:03.000137 | Kathie |
clojurians | clojure | what does `(:example-key my-map ::its-not-there)` return? | 2017-11-14T15:40:08.000658 | Willow |
clojurians | clojure | it returns not-there | 2017-11-14T15:40:44.000412 | Kathie |
clojurians | clojure | so all evidence points to the key not existing in the map, except for the `keys` function | 2017-11-14T15:41:06.000180 | Kathie |
clojurians | clojure | also to be clear, i have code that's supposed to add that key and value to the map, so it not being there is problematic | 2017-11-14T15:41:40.000042 | Kathie |
clojurians | clojure | not sure what could be causing this behavior | 2017-11-14T15:41:54.000178 | Kathie |
clojurians | clojure | is it a record by any chance? | 2017-11-14T15:42:19.000330 | Willow |
clojurians | clojure | it's reframe app-db | 2017-11-14T15:42:33.000423 | Kathie |
clojurians | clojure | which i thought was just an atom | 2017-11-14T15:42:46.000394 | Kathie |
clojurians | clojure | it's a `reagent/atom` | 2017-11-14T15:43:43.000233 | Kathie |
clojurians | clojure | ```app:cljs.user=> (:search-lol @re-frame.db/app-db ::but-why?)
:cljs.user/but-why?
app:cljs.user=> (keys @re-frame.db/app-db)
(:schema
:errors
:audio-label
:audio-player
:loaded
:duration
:routes-initialized?
:search-lol
:token
:active-page
:models
:status
:path-array
:file-download
:playing
:position
:page-query
:audio
:url-data
:location
:user
:audio-type)``` here's the code incase i'm doing something obviously dumb | 2017-11-14T15:50:41.000355 | Kathie |
clojurians | clojure | What is `(type @re-frame.db/app-db)`? | 2017-11-14T15:51:48.000281 | Adelaida |
clojurians | clojure | cljs.core/PersistentHashMap | 2017-11-14T15:52:02.000479 | Kathie |
clojurians | clojure | its possible to get the current localized datetime without any libs in clojure | 2017-11-14T15:52:14.000078 | Amado |
clojurians | clojure | ? | 2017-11-14T15:52:15.000013 | Amado |
clojurians | clojure | <@Kathie> - How about `(let [db @re-frame.db/app-db] (prn 'keys (keys db)) (:search-lol db :no-dice))` (to be sure the value isn't changing out from under you)? | 2017-11-14T15:53:23.000415 | Adelaida |
clojurians | clojure | what does `(->>(keys @re-frame.db/app-db) (map name))` show? | 2017-11-14T15:53:54.000460 | Jonas |
clojurians | clojure | you can make a keyword with a space in it | 2017-11-14T15:54:00.000196 | Jonas |
clojurians | clojure | it might not be it, but might explain the weird behaviour | 2017-11-14T15:54:24.000097 | Jonas |
clojurians | clojure | ```app:cljs.user=> (let [db @re-frame.db/app-db] (prn 'keys (keys db)) (:search-lol db :no-dice))
keys (:schema :errors :audio-label :audio-player :loaded :duration :routes-initialized? :search-lol :token :active-page :models :status :path-array :file-download :playing :position :page-query :audio :url-data :location :user :audio-type)
keys (:schema :errors :audio-label :audio-player :loaded :duration :routes-initialized? :search :token :active-page :models :status :path-array :file-download :playing :position :page-query :audio :url-data :location :user :audio-type)
:no-dice
app:cljs.user=> keys (:schema :errors :audio-label :audio-player :loaded :duration :routes-initialized? :token :active-page :models :status :path-array :file-download :playing :position :page-query :audio :url-data :location :user :audio-type)
``` | 2017-11-14T15:54:25.000153 | Kathie |
clojurians | clojure | not sure why it printed 3 times | 2017-11-14T15:54:32.000619 | Kathie |
clojurians | clojure | checking for something like `(keyword "search-lol ")` | 2017-11-14T15:54:45.000461 | Jonas |
clojurians | clojure | ```app:cljs.user=> (->>(keys @re-frame.db/app-db) (map name))
("schema"
"errors"
"audio-label"
"audio-player"
"loaded"
"duration"
"routes-initialized?"
"search-lol"
"token"
"active-page"
"models"
"status"
"path-array"
"file-download"
"playing"
"position"
"page-query"
"audio"
"url-data"
"location"
"user"
"audio-type")``` | 2017-11-14T15:55:06.000097 | Kathie |
clojurians | clojure | ¯\_(ツ)_/¯ | 2017-11-14T15:55:23.000383 | Jonas |
clojurians | clojure | also this is the db that i reset! the atom to for it to get in this state | 2017-11-14T15:55:35.000265 | Kathie |
clojurians | clojure | ```(-> db
(assoc-in [:status :search-results-fetch audio-type] :success)
(assoc-in [:search-lol :search-results] results))``` | 2017-11-14T15:55:48.000549 | Kathie |
clojurians | clojure | seems pretty straightforward to me so i dunno whats up | 2017-11-14T15:56:00.000562 | Kathie |
clojurians | clojure | note: db doesn't start with `(-> db :search-lol :search-results)` existing | 2017-11-14T15:56:21.000081 | Kathie |
clojurians | clojure | My next guess was unicode weirdness, but if you typed in `:search-lol` in the `assoc` then that's surely not it. | 2017-11-14T15:56:28.000350 | Adelaida |
clojurians | clojure | i assume assoc-in automatically creates a map for them | 2017-11-14T15:56:30.000531 | Kathie |
clojurians | clojure | yea | 2017-11-14T15:57:03.000389 | Kathie |
clojurians | clojure | and it does automatically create the nested maps: ```app:cljs.user=> (assoc-in {} [:test :nested] true)
{:test {:nested true}}``` | 2017-11-14T15:57:42.000677 | Kathie |
clojurians | clojure | so im at a complete loss | 2017-11-14T15:57:46.000430 | Kathie |
clojurians | clojure | <@Amado> - Should be able to use the Java date/time API without any libs. <https://docs.oracle.com/javase/tutorial/datetime/iso/index.html> | 2017-11-14T15:59:40.000316 | Adelaida |
clojurians | clojure | <@Kathie> - you've stumped me! ¯\_(ツ)_/¯ | 2017-11-14T15:59:58.000472 | Adelaida |
clojurians | clojure | thanks for trying lol, i have no idea what could be the issue | 2017-11-14T16:01:04.000748 | Kathie |
clojurians | clojure | what does that print?```(let [db @re-frame.db/app-db]
(doseq [k (keys db)]
(prn k (= k :search-lol) (contains? db k) (get db k ::not-found))))``` | 2017-11-14T16:01:52.000464 | Jonas |
clojurians | clojure | just added `(= k :search-lol)` as something to print | 2017-11-14T16:04:43.000443 | Jonas |
clojurians | clojure | ok so this is really strange | 2017-11-14T16:06:43.000453 | Kathie |
clojurians | clojure | prn prints the results twice, and the first time it prints it, :search-lol is there | 2017-11-14T16:07:01.000424 | Kathie |
clojurians | clojure | `:search-lol true true {:search-results [{:au...` | 2017-11-14T16:07:46.000167 | Kathie |
clojurians | clojure | but then it start printing everything again and an old key that should no longer be in there got printed out too | 2017-11-14T16:08:19.000448 | Kathie |
clojurians | clojure | how are you printing the value? | 2017-11-14T16:08:43.000488 | Jonas |
clojurians | clojure | ie. are you using a repl | 2017-11-14T16:08:56.000344 | Jonas |
clojurians | clojure | or putting it as a top level form in a cljs file | 2017-11-14T16:09:09.000634 | Jonas |
clojurians | clojure | repl | 2017-11-14T16:09:18.000222 | Kathie |
clojurians | clojure | lein fighwheel in intellij | 2017-11-14T16:09:34.000075 | Kathie |
clojurians | clojure | seems like the app + dev tools might be in a weird state | 2017-11-14T16:11:57.000100 | Jonas |
clojurians | clojure | yea lemme restart it | 2017-11-14T16:12:10.000312 | Kathie |
clojurians | clojure | there are something things can cause a figwheel refresh | 2017-11-14T16:13:11.000458 | Jonas |
clojurians | clojure | where it will rerun all the top level forms in your code | 2017-11-14T16:13:30.000475 | Jonas |
clojurians | clojure | like saving a file | 2017-11-14T16:13:38.000534 | Jonas |
clojurians | clojure | maybe there’s something with autosave and not having the state setup to make figwheel happy (eg. using `(def state (atom {}))` instead of `(defonce state (atom {}))` | 2017-11-14T16:14:05.000209 | Jonas |
clojurians | clojure | I sometimes hit use-cases for this FN in threading macros. Is there a better/builtin implementation, or suggestions on the name?
```
(defn pred-or-nil
[pred? v]
(when (pred? v) v))
``` | 2017-11-14T16:26:33.000004 | Lonna |
clojurians | clojure | <@Jonas> idk i'm at a loss. something weird is definitely happening because it's worked fine with every other key every tried previously | 2017-11-14T16:27:49.000018 | Kathie |
clojurians | clojure | the repl doesn't seem trustworthy, so i'm tryign to see if i dissoc the key somewhere in my code | 2017-11-14T16:28:20.000057 | Kathie |
clojurians | clojure | <@Kathie> did you try it from a command-line repl? | 2017-11-14T16:31:07.000287 | Marx |
clojurians | clojure | I guy I work with was having some really weird issues that cleared up when he deleted the contents of the /target dir, fwiw | 2017-11-14T16:31:53.000561 | Marx |
clojurians | clojure | not sure how i'd recreate the state of the app from the cli | 2017-11-14T16:31:55.000431 | Kathie |
clojurians | clojure | hm | 2017-11-14T16:32:00.000194 | Kathie |
clojurians | clojure | lemme delete mine | 2017-11-14T16:32:03.000375 | Kathie |
clojurians | clojure | Oh that’s right, I was thinking clj not cljs, nvm | 2017-11-14T16:32:21.000332 | Marx |
clojurians | clojure | but maybe the /target thing will help | 2017-11-14T16:32:31.000537 | Marx |
clojurians | clojure | it does seem like a weird situation. I would check to make sure that you’re following the tips for reloadable code, <https://github.com/bhauman/lein-figwheel#writing-reloadable-code>. I would also try some of these tests outside of the figwheel repl to try to isolate the issue | 2017-11-14T16:36:56.000280 | Jonas |
clojurians | clojure | in the past, Ive added debug functions like ```(defn ^:export debugprints []
(let [db @re-frame.db/app-db]
(doseq [k (keys db)]
(prn k (= k :search-lol) (contains? db k) (get db k ::not-found)))))``` | 2017-11-14T16:38:17.000307 | Jonas |
clojurians | clojure | and then you can call `my.namespace.debugprints()` from the dev console | 2017-11-14T16:38:35.000259 | Jonas |
clojurians | clojure | ahh cool tip | 2017-11-14T16:38:57.000242 | Kathie |
clojurians | clojure | (and yea lein cleaning and deleting /target didn't help) | 2017-11-14T16:39:11.000392 | Kathie |
clojurians | clojure | Is there a way to run lein tasks from the repl? | 2017-11-14T17:23:17.000424 | Alix |
clojurians | clojure | Should some-> be able to have as-> contained within it? | 2017-11-14T17:40:17.000597 | Earlie |
clojurians | clojure | ```
user=> (some-> 1 (as-> % (+ % %)))
2
user=>
``` | 2017-11-14T17:43:53.000349 | Rebeca |
clojurians | clojure | <@Earlie> anecdotally, I remember having issues with it a few months ago. I usually bust out <https://github.com/rplevy/swiss-arrows> when I need improved threading | 2017-11-14T17:44:21.000174 | Lonna |
clojurians | clojure | the -> macros are purely transformations of form, usually when people have trouble with them it is because they expect them to be aware of semantics | 2017-11-14T17:45:06.000238 | Rebeca |
clojurians | clojure | Alright, I'd changed a -> into an as->; I needed to nest my original -> inside the new as-> which was inside some->. My mistake. | 2017-11-14T17:46:53.000326 | Earlie |
clojurians | clojure | Huh, <@Lonna>, I'll have to look into that. | 2017-11-14T17:47:03.000175 | Earlie |
clojurians | clojure | that is too many arrorws | 2017-11-14T17:47:14.000515 | Rebeca |
clojurians | clojure | Yeah, probably. | 2017-11-14T17:47:21.000074 | Earlie |
clojurians | clojure | It doesn't actually look too bad in reality. | 2017-11-14T17:47:34.000109 | Earlie |
clojurians | clojure | you can't actually tell if it is correct | 2017-11-14T17:47:48.000082 | Rebeca |
clojurians | clojure | that is too many | 2017-11-14T17:47:55.000317 | Rebeca |
clojurians | clojure | ```

``` | 2017-11-14T17:48:05.000262 | Earlie |
clojurians | clojure | that is gross | 2017-11-14T17:48:59.000355 | Rebeca |
clojurians | clojure | Fair enough. Do you have a specific way you'd change it? | 2017-11-14T17:49:14.000183 | Earlie |
clojurians | clojure | The alternative I was running into was having more than 2 exit points. (Duplicating my redirect to /login on multiple branches) | 2017-11-14T17:49:54.000500 | Earlie |
clojurians | clojure | no, I think a good start would be breaking it up, pulling out some helper functions | 2017-11-14T17:50:01.000301 | Rebeca |
clojurians | clojure | agree with the breaking it apart | 2017-11-14T17:50:09.000255 | Guillermo |
clojurians | clojure | Good call there. I definitely will. This was largely just a matter of getting it working. | 2017-11-14T17:50:31.000032 | Earlie |
