The implementation of clarify best practice for tool dependencies.

See https://github.com/golang/go/issues/25922#issuecomment-412992431

Features

  • Manage versions of tools dependencies, and build them with specified version
  • Does not introduce new mechanisms to manage tool dependencies
  • Only 2 commands that you use: --add and --build

Usage

gex --add [packages...]

Add a new tool to dependencies:

$ gex --add github.com/golang/mock/mockgen

The tool will be managed in tools.go and its version will be managed by Modules or dep.

$ cat tools.go
// Code generated by github.com/izumin5210/gex. DO NOT EDIT.

// +build tools

package tools

// tool dependencies
import (
        _ "github.com/golang/mock/mockgen"
)

// If you want to use tools, please run the following command:
//  go generate ./tools.go
//
//go:generate go build -v -o=./bin/reviewdog github.com/golang/mock/mockgen

$ cat go.mod | grep mock
        github.com/golang/mock v1.1.1 // indirect

go generate ./tools.go

Build executable binaries into $PWD/bin.

$ go generate ./tools.go
