Add support for golangci-lint init

[remyleone]

Your feature request related to a problem? Please describe.

When I'm bootstrapping a project, I would like to create a default golangci-lint configuration file. The problem is that I don't have a quick command to type that will create this default configuration file for me.

Describe the solution you'd like.

I would like to have a command such as:

golangci-lint init

or even

golangci-lint config init

Once this command is run, a .golangci-lint.yml file is created inside my current directory. Then I can run golangci-lint and it will natively pick up this file.

Describe alternatives you've considered.

I could copy and paste from previous project but the problem is that linters come and go and it is not easy to know which one are deprecated and the one that are still used.
With an init command I would always be sure to have the latest and recommended linters enabled for my project

Additional context.

I could copy and paste from previous project but the problem is that linters come and go and it is not easy to know which one are deprecated and the one that are still used.

There are 10 deprecated linters on 113:

• ifshort (2022)
• structcheck (2022)
• varcheck (2022)
• deadcode (2022)
• exhaustivestruct (2022)
• nosnakecase (2022)
• golint (2021)
• maligned (2021)
• interfacer (2021)
• scopelint (2021)

We can improve the deprecated workflow but deprecating a linter happens very rarely.
The majority have been deprecated because of missing support of generics (related to go1.18 in 2022).

There are new linters often but it's a user's choice to enable them or not.
We improved the doc with the Since attribute to provide information to help with that.
https://golangci-lint.run/usage/linters/

We can do better, and we will do better.

The problem is that I don't have a quick command to type that will create this default configuration file for me.

The only default configuration golangci-lint has is no configuration file: the set of default linters.

With an init command I would always be sure to have the latest and recommended linters enabled for my project

There are no recommended linters: the right linters and the right configuration depend on projects and users' preferences.

I think the real need behind this issue is the same as #1141.

Here's a fairly new discussion about the topic of getting a default config as well #4393
