problem

I found this maybe-bug with SCI via Clerk…

I built custom JS with this namespace:

(ns mathbox.clerk-ui
  (:require ["three" :as three]
            [nextjournal.clerk.sci-env]
            [sci.ctx-store]
            [sci.core :as sci]))

(def three-ns
  (-> (into {}
            (map (fn [[k v]] [(symbol k) v]))
            (.entries js/Object three))))

(sci.ctx-store/swap-ctx!
 sci/merge-opts
 {:namespaces  {'three three-ns}})

then, in my clerk viewer, I can call constructors with the new keyword:

(js/console.log (new three/Color 0xff4136))

and I see

but if I call (three/Color. 0xff4136) instead (ie with dot notation) I get

Thanks, appreciate the report! It would save me time if you can make isolated repros without project specific config, like this:

(sci/eval-string "(new foo/String nil)" {:namespaces {'foo {'String js/String}}})
#object[String null]

vs:

cljs.user=> (sci/eval-string "(foo/String. nil)" {:namespaces {'foo {'String js/String}}})
Execution error (ExceptionInfo) at (<cljs repl>:1).
Could not resolve symbol: String

Yes, thank you for the nudge here, I will do this going forward! (Assuming that what you have here is enough repro for this issue, I can do more if not).

[borkdude]

Yes, this is sufficient
