args detected as import ?

[jycouet]

Hi,
I'm trying to go to ESLint v9, and started from scratch my config (not that easy bump).

I don't know why but with this config

rules: {
  'no-unused-vars': 'off',
  '@typescript-eslint/no-unused-vars': 'off',
  'unused-imports/no-unused-imports': 'error',
  'unused-imports/no-unused-vars': 'error',
}

I get this error:

I'm expecting to have unused-imports/no-unused-vars, but I don't get why I'm getting unused-imports/no-unused-imports (same position & variable)
event is not an import.

Do you have a default repro template for me to try reproducing it somewhere ?

Thank you for your help.

Do you have a default repro template for me to try reproducing it somewhere ?

Sorry we don't. But I guess it shouldn't be hard to setup a basic node project to reproduce? I think we could not maintain repro template for every single plugin and keep them in sync.

From a glance I can't tell why it would happend. I'd appreciate a repro for us to investigate. Thanks

Thank you for the reply.

I did a repro https://github.com/jycouet/eslint-repro-unused-imports
But was not able to reproduce the issue! :(

I tried to go as close as my "big" repo (growing it step by step):

• using decorator
• using an external plugin @kitql/eslint-config that has eslint-plugin-unused-imports configured

On my side, it would be the variable titi that triggers unused-imports/no-unused-imports. But it's not an import, it's an arg of a function.

I also looked into ESLint Config Inspectorv0.5.4 (thx for this nice tool), and was able to explore rules & plugins & co... But didn't find where I'm screwing things.

Would you have an idea of where else should I explore ?
Is there a way to run the rule in debug mode so that I can trace what's the root cause ?

Let me know

[jycouet]

I started to console.log to in the node_modules/ /index.mjs to see if I can find something.

And in the "wrong" report, parent is null. (In these lines https://github.com/sweepline/eslint-plugin-unused-imports/blob/master/src/rules/predicates.ts#L18-L26)

[antfu]

I don't know under what circumstances the parent would be null, but yeah, indeed, there was a bug on our side. Thanks.

[jycouet]

Thank you, I'll test it ASAP 👍

[jycouet]

Do you know when it will be released?

[antfu]

It's released now. There was a release failure I didn't notice before going bed 😅

[jycouet]

Haha, thx again ✌️

Still seeing this on 4.1.4 with the error argument on catch blocks

@antfu were you able to have a look?
