Hey, I'm a first time user of GitHub and would love to know if I can assist you in any way? @kodyclemens

[kodyclemens]

@Esh08 Unfortunately I think this issue may have to wait as Codeclimate does not yet support the new gem, which is resulting in failing tests.

Thanks! That's too bad - maybe we can mark the PR with that and then merge it hopefully down the road once it is supported? Thank you for your help!!!

@kodyclemens @jywarren CodeClimate currently only supports rubocop ~> 0.52.0. We had this same issue with mapknitter at publiclab/mapknitter#547

[nstjean]

Is this needed now? This link says that codeclimate should support rubocop-performance:
codeclimate/codeclimate-rubocop#166

Let me know and I'll create a pull request.

Hi there, I would like to take this issue (as a first-timers-only) :)

[cesswairimu]

@Lisa-Caton go ahead its all yours

[Lisa-Caton]

great - I'll get started asap! Thanks so much.

I think I am stuck. When I did the pr it looks like my branch isn't passing checks with my submission. https://github.com/publiclab/plots2/pull/6437 I've only added the 2 lines to the code. And when I ran rubocop --require rubocop-performance it ran without errors on my terminal. (92 files inspected, 126 offenses detected) Since I am able to run the working command locally, I'm not sure what to do next.

Hi @Lisa-Caton I will take a look

[Lisa-Caton]
