Typescript-eslint: typings for "working with plugins" side of eslint

[G-Rath]

As part of converting eslint-plugin-jest to typescript, I found that there are no typings for the plugins side of eslint.

Is that something typescript-eslint would be interested in covering?

having a look into the attached PRs - I see you're looking for processor types?

Sure thing!
Essentially the things that exist in experimental-utils is what was in the DefinitelyTyped types.

We'd love to have types for any and all things eslint.

Awesome!

Woops sorry I was meant to link to that header specifically - the anchor tag seems to have gotten lost 😬

I see you're looking for processor types?

For now yes, but I'd love to have as much types as possible - the index.ts export is completely untyped :(

I'm happy to help try & provide these types - at the very least it'll serve as a strawman to encourage refinement.

I'll start w/ adding types for the object described in the "Processors in Plugins" section of that page.

Just going to put this here for when I look to do the typings:

I believe this issue has been addressed through a mixture of enhancements to experimental-utils and updates to DefinitelyTyped, so closing for now
