Does anyone have any links of blogs or videos of making clojure script work with react native that is not outdated? Most of the stuff I find is outdated and does not work with latest versions. Bonus if it's done with shadow-cljs 🙏:skin-tone-2:

thomas14:09:18

there is a #react-native channel and if I am not mistaken there is something called krell..

thheller15:09:57

can you elaborate on what doesn't work? the integration is quite simple and should just work?

Siddarth Kumar15:09:01

Sure I'm afk but Il share detailed logs once I get a chance

anyone know if devcards (https://github.com/bhauman/devcards) is abandoned? There's some pretty simple npm dependency updates needed to get it working with modern cljs tooling, everytime I touch a project that uses it I have to figure out which stale highlight.js and marked versions are needed to make it happy. It also seems like modern shadow-cljs versions are broken with highlight.js, so have to downgrade shadow-cljs too.. shadow error on 2.20.2:

Hi there, I’ve been playing with cljs and boot and cider but I got an error issuing (start-repl) right after cider-jack-in

Does that error have a stacktrace?

I might be wrong, you mean this?

Judging by the code, you should call cljs-repl-env at some point. At which point I don't know though - I barely used boot something like 8 years ago and I definitely wouldn't recommend using it nowadays, if that's an option.

leif22:09:43

I am trying (and failing) to use a custom cljs.tools.reader library in a ClojureScript Project. I have the following deps.edn file: 

{:deps {org.clojure/clojure {:mvn/version "1.10.0"}
        org.clojure/clojurescript {:mvn/version "1.11.60"}
        org.clojure/tools.reader {:local/root "/home/leif/src/tools.reader"}}
 :aliases {:run {:main-opts ["-m" "cljs.main" "--compile"
                             "sample.core" "--repl"]} }
 :paths ["src"]}
And samp.core is: 
(ns samp.core
  (:require
   [cljs.tools.reader :refer [read read-string]]))
But whenever I build this (with clojure -M:run , I get the following error: 
Exception [...]
Caused by: clojure.lang.ExceptionInfo: No such namespace: cljs.tools.reader, could not locate cljs/tools/reader.cljs, cljs/tools/reader.cljc, or JavaScript source providing "cljs.tools.reader" in file /home/leif/src/is-small/src/samp/core.cljs {:tag :cljs/analysis-error}

(Note that I am using local/root for tools.reader, when I replace it with {:mvn/version "1.3.6"} it works fine.

bronsa22:09:17

src/main/cljs is not included in the paths for t.r's deps.edn , which I assume local/root would use

leif22:09:01

@bronsa It is in the tools.reader deps.edn file.

leif22:09:26

(I have the latest head checked out in the folder /home/leif/src/tools.reader, so I would imagine it should be a compatible version.)

leif22:09:53

Ah, you're right.

leif22:09:20

So then, why does it work at all when I switch to {:mvn/version "1.3.6"}?

bronsa22:09:54

because the published jar is not built using the deps.edn , in that repo it's only there for dev convenience (and I only used it for clojure)

leif22:09:23

Ah, when I add src/main/cljs to the paths the error seems to go away

leif22:09:25

So thanks. 😄
