Show Rubocop show warning without autoformatting

[abrausch]

Hi,
is there a possibility to show some rubocop warning but ignore them for formatting? I had a problem with
Lint/UselessAssignment
which was removing the useless assignments when I saved the code.
To fix that I set it to false in my .rubocop.yaml
But I would like to see the warning inside my editor but because I save quite often I would like to disable this option for formatting.
Is this possible?

Greetings and thx
Alex

You can configure your project Rubocop config file for it.

Modifying the Rubocop config file looks like the right option. I confirmed that I could enable a cop and disable its AutoCorrect setting so the warning appeared in the editor but formatting didn't change it.
