Getting this error while linting datatype.clj :

src/tech/v3/datatype.clj:167:19: error: Unresolved symbol: idx
src/tech/v3/datatype.clj:167:19: warning: Unresolved namespace hooks.datatype. Are you missing a require?

cmd line I am using is https://github.com/cnuernber/dtype-next/blob/clj-kondo-builtin/scripts/clj-kondo.

src/tech/v3/datatype.clj:167:19: warning: Unresolved namespace hooks.datatype. Are you missing a require?

Probably your hook is generating some code with this name in it?

Yeah that's the issue. Your macro is defined in a namespace hooks.*. I recommend renaming this namespace to the same namespace as where the original namespace is occurring.

It's recommended for exported config hook code to use unique namespaces anyway and the convention is <org>/your_lib/file.clj or so, similar to how you would do it in your lib

^ @chris441

I put the config file exactly there, cnuernber/dtype-next/config.edn. Then it will have an entry that is {:macroexpand {tech.v3.datatype/make-reader tech.v3.datatype/make-reader}} with the code under resources/clj-kondo.exports/cnuernber/dtype-next/tech/v3/datatype.clj. Is that the recommendation?

Also, I have a few namespaces that simply extend protocols but aren't used directly in the file. Is there a good way to annotate those namespaces or the require itself?

yeah

(to the first question)

I don't understand the need for "annoting those namespaces".

Can you clarify with an example?

(ns a.b.c
  (:require [protocol-defs :as pdef]
            [protocol-impls]))

(defs/use-protocol :a)  

Something like there where there are protocol or multimethod implementations but the namespace doesn't export anything aside from that.

I still don't understand. What is the problem?

unused namespace warning

because you're not using pdef?

if you don't add an alias then clj-kondo will assume you are requiring only for side effects

Ah, ok, there it is. The times I have seen it I had an alias, sorry, that clears it up.

gotcha
