You use the --only command line option. For example

rubocop --only Metrics
rubocop --only Style/FormatString,Style/HashSyntax

Thanks, but how to do it with config file?

[jonas054]

I'm not sure why you would want to do that exactly, but the normal workflow when starting to use RuboCop is to run rubocop --auto-gen-config, then add inherit_from: .rubocop_todo.yml in .rubocop.yml. It achieves the same goal as disabling all cops, except that the cops that have not found any offenses remain enabled.

I was wondering the same thing. I don't want to inherit all of the default style checks that Rubocop provides by default and would much rather just specify the things we want rather than have to keep going back in to override things. It would be great to be able to just disable_defaults: true or something in the config

Tried messing around in a fork a bit to see if we can just get rid of the default config, but it looks like we're expecting configuration values to be present for all the cops (as opposed to reading the configs and only loading cops that are declared)

Sweet thanks!

This is a great feature, thanks! Is there any ETA on the upcoming release containing this?

It would actually be nice to have the same option for each category. I'm interested in everything except all the Style/

[jonas054]

@pschambacher This issue talks about a few different options, so can you clarify a bit what it is that you want?

[pschambacher]

@jonas054 this is what I was thinking about:

AllCops:
  DisableByDefault: false

Style/AllCops:
  DisableByDefault: true

This way I get all existing (and future) cops enabled except for any existing (and future) Style cops.
Making it the other way around would be "I only care for Style cops"

[jonas054]

That's a good idea. But the syntax should be

Style:
  DisableByDefault: true

Currently, such a setting is silently ignored, which is clearly not what we want.

[pschambacher]

I'm completely fine with this syntax :)

[chadxz]

I came looking for

Metrics:
  DisableByDefault: true

and found this ticket. is anyone working on it?

[bbatsov]

Most likely no.

For people get here later and interested in this, you can find doc at:
https://docs.rubocop.org/rubocop/configuration.html#generic-configuration-parameters

What you want may look like this:

AllCops:
  DisabledByDefault: true
  
Style:
  Enabled: true
