Clojurians Log v2

@smith.adriane I want to try making a productivity app with stuff like timers, and way to store notes

is the app for personal use or will it be distributed to other users?

@smith.adriane I want to try a personal one

i'm not exactly sure why cljfx wasn't a good fit, but it seems like it could work in principle. the folks in #cljfx are pretty responsive if you have questions. if you have cljs experience, an electron app is pretty straightforward. I would recommend something like https://github.com/Day8/re-frame (#re-frame for questions) as an overall framework, browser apis for timing, and then use the https://nodejs.org/docs/latest-v13.x/api/for storage.

@dominicm You may be interested in https://github.com/contribsys/faktory — It’s not in the Java ecosystem, but I would choose this over Quartz or somesuch.

I have not read any of this code, but there are at least a couple of examples of people creating little interfaces in clojure. Here’s one: https://github.com/apa512/clj-faktory

@smith.adriane Thanks a lot

Looks useful, thanks!

I built it after failing to find anything in Clojure that worked like Sidekiq. If anyone wants to try it, it's probably better to look at the tests than the readme.

Quick question I need to perform a function on two sequences/vectors A B, for every item on A with every item on B and collect the results. I know map will operate on nth of A and nth of B, I need A0 to B0, A0-Bn...

(for [a-alem A, b-elem B] (some-expression involving a-alem b-elem here))

Is it possible to inherit deps from another alias in deps.edn?

@karol.wojcik Not in deps.edn itself, only from the command line you can merge alias deps together

There was a conversation about this recently in #tools-deps - there might be something like this one day

Actually that would be useful for convenience, but I know that allowing it would cause a mess in classpath.

You're not the first to ask

Since there’s only one element in the meta, there’s the tiny abbreviation of saying: (def ^:private your-var) But it’s not much

Is there a preference between returning a) {k v} versus b) [k v] from map when using into? I have always used the latter. Seems like there may also be some perf considerations. Have done absolutely zero testing in that regard. For example...

(into {}
  (map (fn [[x y]]
         ;; A
         {x y}
         ;; B
         [x y]))
  my-coll)

Guys, color me shocked. I just found this strange behaviour:

Clojure 1.10.1
user=> (contains? [1 2 3] 1)
true
user=> (contains? [1 2 3] 2)
true
user=> (contains? [1 2 3] 3)
false

common question. check (doc contains?) > Returns true if key is present in the given collection, ... vectors are associative collections from index to value. The docstring walks through this as well

@https://app.slack.com/team/U11BV7MTK Thanks! As I said, maybe I should have posted in #beginners :;)

next time 🙂 buts its a common question. you're not the first. probably not the last to ask either 🙂

lol, okay. Sry for bugging you for the nth-time. Btw, awesome community here

never a bother!

if i don't have time i don't answer.

yes, fair enough

Is there a reason deps does not capture the project name like lein did? Is the current approach to just maintain your own pom.xml?

@shaunxcode For now, yes, but Cognitect have talked about an upcoming tools.build project that we might reasonably expect to address that issue somehow...

(they've said almost nothing publicly about tools.build but given that pom.xml generation/sync'ing is already part of the Clojure CLI to some degree, we might assume they would enhance that in future tooling)

cool I look forward to that! For the time being I will just have a skeletal project.clj I use for lein deploy etc.
