please try with the most recent version of clj-kondo on the command line, to avoid any downstream involvement

can't repro using this example alone:

(ns something.something)

this is not the real namespace I have, but I think the ns name is irrelevant in that case

is it possible to make a minimal repro though and do it with clj-kondo on the command line and send that repro here?

❯ clojure-lsp --version clojure-lsp 2022.05.31-17.35.50 clj-kondo 2022.05.31

still here

I ll check on the command-line

same error on the cli

can you show me your CLI invocation?

❯ clj-kondo --lint . ./some-random-file.clj:0:0: error: Can't parse ../some-random-file.clj, No implementation of method: :tag of protocol: #'clj-kondo.impl.rewrite-clj.node.protocols/Node found for class: nil

same result with ❯ clj-kondo --cache false --lint .

what is in some-random-file.clj?

protocols & implems of these etc etc, but the problem lies here. If I remove half of the code the issue goes away, I ll try to bisect the thing until I find the culprit

ah found it

there was a buggy defmulti

it had no dispatch fn defined, something like (defmulti foo)

odd that I got pos 0:0 flagged tho

try with a file with that:

(ns foo)

(defmulti foo)

you'll get the same issue

aaah ok

yes, when something unexpected happens, then clj-kondo doesn't know where to put the issue and it just puts it at 0:0

but we should make this more robust. feel free to post an issue

sure

thanks

Currently not but feel free to post an issue

will do

I think there were also some requests recently to lint access from namespace X to namespace Y etc

which might also be nice to incorporate

you can deprecate in the namespace metadata

https://github.com/clojure/clojure/blob/master/src/clj/clojure/parallel.clj#L9 for example

I guess that's not actually metadata, but it could be

that's proposed in https://clojure.atlassian.net/browse/CLJ-706 (not sure if that will ever get looked at, Rich was noncommittal the last time he did)

https://github.com/clj-kondo/clj-kondo/issues/1721 issue filed 🙂

@U064X3EF3 those namespaces out of my control. They are coming from a library and to alter metadata I have to load it first which is exactly what I'm trying to avoid.

gotcha

Thanks! There's also already an issue for warning on deprecated ns metadata

FWI - https://github.com/clj-kondo/clj-kondo/pull/1724 @U04V15CAJ adding new linter was surprisingly easy, kudos for the architecture of kondo

Nice. Maybe we should add some example of using an ns group + the in option? Maybe :from is a better name than :in ?

In my head in emerged from the sentence: "In namespaces #{X Y Z} discourage usage of namespace A" can't make such sentence with from but probably it is a problem of my english 🙂

We already use the word :from in the analysis here: https://github.com/clj-kondo/clj-kondo/blob/master/analysis/README.md so imo that would be more consistent

The namespace A is used from namespaces X Y Z. Valid English I think?

sounds right to me, I'll change it

@U04V4KLKC I invited you to #clj-kondo-dev for some PR feedback

Thanks!
