gogroupimports

Similar to goimport, but makes the grouping clearer.

The gogroupimports tool organizes the Go imports and rewrites them according to the following:

• First group: The standard library packages
• Next group: 3rd party library packages
• Last group: local packages

example:

import (
	// The standard library packages
	"context"
	"fmt"
	"testing"

	// 3rd party library packages
	"google.golang.org/grpc"
	"google.golang.org/grpc/codes"
	"google.golang.org/grpc/status"
	"google.golang.org/protobuf/proto"

	// local packages
	"github.com/atotto/awesome"
)

Installation

go install github.com/atotto/gogroupimports@latest
go install golang.org/x/tools/cmd/goimports@latest

Example of use

before:

import (
	"testing"

	"context"
	"fmt"
	
	"github.com/atotto/awesome"
	"google.golang.org/grpc"
	"google.golang.org/grpc/codes"
	"google.golang.org/grpc/status"
	
	"google.golang.org/protobuf/proto"
)

gogroupimports -local github.com/atotto/awesome -w foo.go

after:

import (
	"context"
	"fmt"
	"testing"

	"google.golang.org/grpc"
	"google.golang.org/grpc/codes"
	"google.golang.org/grpc/status"
	"google.golang.org/protobuf/proto"

	"github.com/atotto/awesome"
)

vs goimports

The goimports tool does not delete empty line. Like this:

goimports -local github.com/atotto/awesome -w foo.go

import (
	"context"
	"fmt"
	"testing"

	"google.golang.org/grpc"
	"google.golang.org/grpc/codes"
	"google.golang.org/grpc/status"

	"github.com/atotto/awesome"
	
	"google.golang.org/protobuf/proto"
)
