golangci-lint-migrate

Configuration migrator

This is a tool that helps you migrate from an existing golangci-lint configuration to the new v5 configuration.

The biggest change is that v5 uses checks for everything that can be turned on and off individually.

Usage

Just run the code and point it to your .golangci.yml file.

golangci-lint-migrate .golangci.yml
