Motivation

As a Go developer, I actively use goimports as a code formatter, but it has
non-deterministic behavior that affects a final diff. For example, for the input

import (
	"context"
	"github.com/pkg/b"
	"github.com/pkg/a"

	"github.com/pkg/y"
	"github.com/pkg/x"
	"github.com/pkg/z"
)

the output will be

import (
	"context"

	"github.com/pkg/a"
	"github.com/pkg/b"

	"github.com/pkg/x"
	"github.com/pkg/y"
	"github.com/pkg/z"
)

The proper result for me is

import (
	"context"

	"github.com/pkg/a"
	"github.com/pkg/b"
	"github.com/pkg/x"
	"github.com/pkg/y"
	"github.com/pkg/z"
)

So, I need to patch its behaviour and make a result deterministic.

What's changed

• The goimports has the deterministic behaviour.
• The tool is available by brew install octolab/tap/goimports.
• The installation is also possible by

  $ curl -sSfL https://install.octolab.org/goimports | sh -s -- -b /usr/local/bin
