If I use a fully qualified ns like ( stream) clj-kondo warns with Unresolved namespace . Are you missing a require? but its fine with (clojure.string/split ...). Is this problem?

You are always supposed to add a require even if it works, since you should not rely on a namespace already being loaded elsewhere

but arent namespaces like and clojure.string are loaded by default?

no

well clojure.string is, but you should not rely on it

e.g. if clojure.spec loads clojure.string, you're lucky, but if spec doesn't you're not. it's an implementation detail

i mean i can do a () in a plain REPL without requiring, it still means something else has loaded it?

yeah, maybe your REPL tooling or Clojure main has, but that doesn't mean it will still have been loaded in a compiled artifact for example

According to Alex Miller you should not rely on it. I take his word for it.

ah, good to know. thanks! 😄

shouldn't it warn for clojure.string too? just to be consistent? this diff is what bothered me in the first place

kondo you mean? doesn't it?

no

okay somethings up with my editor then :thinking_face:

try flycheck-verify-setup

can you past the full namespace?

ah now i see it

long back there is a require

🙂

thanks anyways 🙂
