Smart imports

If you want to format imports in your golang source files according to the standards of your team, this tool might be handy.

Standard tool goimports doesn't regroup imports. For example if you have a file

package main

import (
    "context"
    "os"

    "github.com/pkg/errors"

    "github.com/bradfitz/gomemcache"
)

goimports wouldn't do anything with it. But smartimports would group imports into 2 groups:

package main

import (
    "context"
    "os"

    "github.com/pkg/errors"
    "github.com/bradfitz/gomemcache"
)

Installation

For go 1.16: go install github.com/pav5000/smartimports/cmd/smartimports@latest

For earlier versions of go: go get github.com/pav5000/smartimports/cmd/smartimports

Usage

Simple example:

smartimports (formats files in the current dir and all subdirs)

Complex example: smartimports -path ./my-project -exclude ./my-project/pb_pkg -local github.com/someuser/my-project

With option -path you can specify a directory which should be processed (by default smartimports process current directory).

With option -exclude you can specify prefixes for paths which shouldn't be processed. Prefixes should match the style of -path option. You can check details with -v. If your -path is absolute, -exclude should be absolute too.

With option -local you can specify a comma-separated list of prefixes for packages which should be grouped into 3rd group. Some teams put their local packages into it.

With option -v you can see verbose output of traversing through directories and files.
