GCI

GCI, a tool that control golang package import order and make it always deterministic.

It handles empty lines more smartly than goimport does.

Download

$ go get github.com/daixiang0/gci

Usage

$ gci -h
usage: gci [flags] [path ...]
  -d	display diffs instead of rewriting files
  -local string
    	put imports beginning with this string after 3rd-party packages, only support one string
  -w	write result to (source) file instead of stdout

Examples

Run gci -w -local github.com/daixiang0/gci main.go and you will handle following cases.

simple case

package main
import (
  "golang.org/x/tools"

  "fmt"

  "github.com/daixiang0/gci"
)

to

package main
import (
  "fmt"

  "golang.org/x/tools"

  "github.com/daixiang0/gci"
)

with alias

package main
import (
  "fmt"
  go "github.com/golang"
  "github.com/daixiang0"
)

to

package main
import (
  "fmt"

  go "github.com/golang"

  "github.com/daixiang0/gci"
)

with comment and alias

package main
import (
  "fmt"
  _ "github.com/golang" // golang
  "github.com/daixiang0"
)

to

package main
import (
  "fmt"

  // golang
  _ "github.com/golang"

  "github.com/daixiang0/gci"
)

with above comment and alias

package main
import (
  "fmt"
  // golang
  _ "github.com/golang"
  "github.com/daixiang0"
)

package main
import (
  "fmt"

  // golang
  _ "github.com/golang"

  "github.com/daixiang0/gci"
)

TODO

  • Support multi-3rd-party packages
  • Support multiple lines of comment in import block
  • Add testcases
