如何批量更改GO软件包的别名？

Question

I want rename many packages across many files. At the same time, I also want to change package aliases. Is there any tool to do that? The ones I find in go/x/tools only change package imports.

I want to go from import "github.com/a/b"

to

import b "github.com/c/d"

There is a cool trick with std tools.

gofmt has an option -r rule which works like this:

gofmt -w -l -r "github.com/a/b -> github.com/c/d" .

where rule have format pattern -> replacement

See gofmt docs

Also there is a gofix tool, but I haven't tried it, see docs and blog
