for example a code like this:

(ns foo.bar (:require [bar :as b]))

{:type :unused-namespace,
  :message "namespace bar is required but never used",
  :level :warning,
  :row 1,
  :end-row 1,
  :end-col 21,
  :col 18,
  :filename "/a.clj"}

it'd be nice to have a :ns bar

Findings generally don't have this information (since this is not output to linter editor integration in general) but I think we could add it, without breaking things :)

PR welcome

thanks 🙂 I don't know clj-kondo code, any tips on what/where change it? I'd love to help 🙂

grep for "is required but never used" and this should be relatively easy to plug in. Usually this is tested either in main_test.clj or unused_namespace_test.clj (or something like this). Grep should also show where this is tested

Thank you! 👀

hmm, but the tests round-trip from the text output, so a test calling the core namespace should be added separately to test for the :ns addition

Let me know if you have any questions

What do you think it's the best, merging https://github.com/clj-kondo/clj-kondo/blob/master/src/clj_kondo/impl/linters.clj#L405`node->line` with something like {:ns ns-sym} and {:refer :refer-sym} for unused-refer lint or adding a name or extra arg for node->line ?

(assoc ... :ns ns-sym)

merge is best avoided, assoc is faster ;)

nice!

Any reason why load the ns with cider fails because of missing deps me.raynes.conch ?

are you running with deps.edn?

You should include the :test alias then

same for lein: with-profiles +test

I'm having a hard time to make cider use the test lein profile :man-facepalming: 😂

This is why I never use cider-jack-in. I always use cider-connect

To be honest, with clj-kondo development, I almost never use a REPL. I always just use the command line

I got it, but yeah, I agree that could work too

maybe in a near future when clojure-lsp uses clj-kondo 😜

clojure -M:clj-kondo --lint - <<< '(+ 1 2 3)' 

@borkdude the tests on main_test don't return the added :ns , I think this is what you meant above right? how can I test that?

sorry for too many questions 😅

This is the draft atm https://github.com/clj-kondo/clj-kondo/pull/1132

@UKFSJSM38 yeah, instead of (lint! ...) you just call (-> (with-in-str "your-code" (clj-kondo.core/run! {:lint ["-"]}) :findings)

so as an API call basically. lint! mimics the command line usage (the primary way in which clj-kondo was initially used)

Got it, should I add that as a new deftest in core_test or a new test ns?

I think you can put it along with the other unused-ns tests

like unused_namespace_test.clj

ok

but also feel free to move the existing ones to unused_namespace_test.clj if that doesn't exist yet

main_test is way too big

yes, I can do that 😄

Done @borkdude, thank you for the help during this 🙂 LMK if any issues with the PR: https://github.com/clj-kondo/clj-kondo/pull/1132
