Closes #40

Thanks for helping out! This module is deprecated and no longer in use though, so won't receive any update :)

@voxpelli Is there an upgrade path from this plugin?

It's still used by eslint-config-prettier, so would love to update it there.

[voxpelli]

@MichaelDeBoey It was deprecated as standard itself no longer needed any of the specific rules from it, having had them superseded by rules from core and/or other plugins I believe

Looks like standard/computed-property-even-spacing is the one and only rule that the prettier config is using

[MichaelDeBoey]

@voxpelli Thanks for creating the issue!

Maybe it's also deprecate/archive this repo?

Maybe it's also deprecate/archive this repo?

Eventually, but for now it’s good that people can still ask questions and such.

It is marked as deprecated on npm and there is a big note about it in the readme: https://github.com/standard/eslint-plugin-standard#deprecated-this-package-isnt-used-by-standard-anymore-as-of-standard-v16-see-httpsgithubcomstandardstandardissues1316
