How did you install golangci-lint?

Your feature request related to a problem? Please describe

In v1, formatters were not separated from linters and could, without any configuration yaml, be enabled via the cli, e.g. like this:

golangling-ci run --enable goimports,gofmt,misspell,unconvert,revive 

After v2, I'm getting an error message:

Error: can't load config: goimports is a formatter
Failed executing command with error: can't load config: goimports is a formatter

@ldez's release blog post mentions that golanglint-ci run will run all formatters from the configuration file as well: https://ldez.github.io/blog/2025/03/23/golangci-lint-v2/#:~:text=The%20formatters%20defined%20in%20this%20section%20are%20automatically%20used%20as%20%E2%80%9Clinter%E2%80%9D%20when%20you%20run%20the%20command%20golangci%2Dlint%20run.

Thus, I would expect that the --enable flag of runalso allows to activate formatters.

Describe the solution you'd like

As before, adding formatters into run --enable should work without issues

Describe alternatives you've considered

Adding configuration files to each repository

Hi, this has already been implemented in #5620 and is available in v2.0.2.

golangci-lint fmt --enable gofmt,goimports

[LukasHeimann]

I've doublechecked the fmt command, but I explicitly mean the run here. As per the blog of the core maintainer, golangci-lint run should, if I have any active formatters in my config, also run the formatters.

Thus, passing them to golangci-lint run --enable gofmt via cli, they should also be loaded. Or the run command should have a separate flag for --enable-formatters, so that there is more clear separation (that seems to be a major design goal of v2).

Background: I'm running the reviewdog integration of this, and that is only calling the run command.

Hello,

Inside v2, a formatter is not a linter.

The formatters are related to the new command golangci-lint fmt.
They are "converted" as linter for convenience, but their main usage is related to this command.

So, a configuration file is required in this context.
