goimports-reviser

Tool for Golang to sort goimports by 3-4 groups(with own linter): std, general, company(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"). -company-prefixes - will create group for company imports(libs inside your organization). Values should be comma-separated.

Configuration:

Cmd

goimports-reviser -rm-unused -set-alias -format ./reviser/reviser.go

You can also apply rules to a dir or recursively apply using ./... as a target:

goimports-reviser -rm-unused -set-alias -format -recursive reviser

goimports-reviser -rm-unused -set-alias -format ./...

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

Options:

Usage of goimports-reviser:
  -apply-to-generated-files
        Apply imports sorting and formatting(if the option is set) to generated files. Generated file is a file with comment which starts with comment '^// Code generated .* DO NOT EDIT\.$'. Generated comment must before package fragment. Optional parameter.
  -company-prefixes string
        Company package prefixes which will be placed after 3rd-party group by default(if defined). Values should be comma-separated. Optional parameters.
  -format
        Option will perform additional formatting. Optional parameter.
  -imports-order string
        Your imports groups can be sorted in your way. 
        std - std import group; 
        general - libs for general purpose; 
        company - inter-org or your company libs(if you set '-company-prefixes'-option, then 4th group will be split separately. In other case, it will be the part of general purpose libs); 
        project - your local project dependencies. 
        Optional parameter. (default "std,general,company,project")
  -list-diff
        Option will list files whose formatting differs from goimports-reviser. Optional parameter.
  -output string
        Can be "file", "write" or "stdout". Whether to write the formatted content back to the file or to stdout. When "write" together with "-list-diff" will list the file name and write back to the file. Optional parameter. (default "file")
  -project-name string
        Your project name(ex.: github.com/incu6us/goimports-reviser). Optional parameter.
  -recursive
        Apply rules recursively if target is a directory. In case of ./... execution will be recursively applied by default. Optional parameter.
  -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.
  -set-exit-status
        set the exit status to 1 if a change is needed/made. Optional parameter.
  -use-cache
        Use cache to improve performance. Optional parameter.

Examples

Before usage:

package testdata

import (
	"log"

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

	"bytes"

)

Example with -company-prefixes-option

Before usage:

package testdata // goimports-reviser/testdata

import (
	"fmt" //fmt package
	"golang.org/x/exp/slices" //custom package
	"github.com/incu6us/goimports-reviser/pkg" // this is a company package which is not a part of the project, but is a part of your organization
	"goimports-reviser/pkg"
)

After usage:

package testdata // goimports-reviser/testdata

import (
	"fmt" // fmt package

	"golang.org/x/exp/slices" // custom package

	"github.com/incu6us/goimports-reviser/pkg" // this is a company package which is not a part of the project, but is a part of your organization
