I like this from the readme:

    It's easy to use Coral as a drop-in replacement for Cobra in existing projects, just let gofmt do the heavy lifting for you:

     gofmt -w -r '"github.com/spf13/cobra" -> "github.com/muesli/coral"' .
     gofmt -w -r '"github.com/spf13/cobra/doc" -> "github.com/muesli/coral/doc"' .
     gofmt -w -r 'cobra -> coral' .
     go mod tidy

Having implemented something to do a similar one off refactor in java for thousands of files, that is a breath of fresh air. In java i had to go code -> AST -> perform manipulations -> generate code from AST (with inevitable long PR’s due to generated code not matching 1:1 with parsed original). After having gone through that i think if i had to repeat again with java I’d probably try harder to use structural find and replace.
