Right imports sorting & code formatting tool (goimports alternative)

goimports-reviser

Tool for Golang to sort goimports by 3-4 groups: std, general, local(which is optional) and project dependencies. Also, formatting for your code will be prepared(so, you don't need to use gofmt or goimports separately). Use additional options -rm-unused to remove unused imports and -set-alias to rewrite import aliases for versioned packages or for packages with additional prefix/suffix(example: opentracing "github.com/opentracing/opentracing-go"). -local - will create group for local imports. Values should be comma-separated.

Configuration:

Cmd

goimports-reviser -file-path ./reviser/reviser.go -rm-unused -set-alias

Example, to configure it with JetBrains IDEs (via file watcher plugin):

  -project-name string
        Your project name(ex.: github.com/incu6us/goimports-reviser). Optional parameter.
  -local string
        Local package prefixes which will be placed after 3rd-party group(if defined). Values should be comma-separated. Optional parameters.
  -output string
        Can be "file" or "stdout". Whether to write the formatted content back to the file or to stdout. Optional parameter. (default "file")
  -rm-unused
        Remove unused imports. Optional parameter.
  -set-alias
        Set alias for versioned package names, like 'github.com/go-pg/pg/v9'. In this case import will be set as 'pg "github.com/go-pg/pg/v9"'. Optional parameter.

	"github.com/incu6us/goimports-reviser/testdata/innderpkg"

	"bytes"

	"github.com/pkg/errors"
)

After usage:

package testdata

import (
	"bytes"
	"log"

Comments(not Docs) for imports is acceptable. Example:

package testdata

import (
    "fmt" // comments to the package here
)

Example with -local-option

Before usage:

package testdata // goimports-reviser/testdata

import (
	"fmt" //fmt package
	"github.com/pkg/errors" //custom package
	"github.com/incu6us/goimports-reviser/pkg" // this is a local package which is not a part of the project
	"goimports-reviser/pkg"
)

After usage:

package testdata // goimports-reviser/testdata

import (
	"fmt" // fmt package

	"github.com/pkg/errors" // custom package

	"github.com/incu6us/goimports-reviser/pkg" // this is a local package which is not a part of the project
