What did you do? Please include the actual source code causing the issue, as well as the command that you used to run ESLint.

This is in a .vue SFC, within the script tag.

import { defineComponent, ref,
  PropType } from 'vue'

ESlint is ran from within VSCode.

What did you expect to happen? The import to not allow line breaks, because 'ImportDeclaration': 'never', is set.

What actually happened? Please include the actual, raw output from ESLint. Line breaks aren’t throwing an error.

Are you willing to submit a pull request to fix this bug? I have no knowledge of eslint internals, but sure, if I can help, more than willing to!

I think it would be best to say “after” and “before”, like in rule details of array-bracket-newline.

I’m going to do this, give me one day.
