定义

Cobra 是 Go 的 CLI 框架

• CLI，command-line interface，命令行界面

使用

注意

• 第一个cmd的USE即使命名了也没有意义，一般保持和项目名一致。

示例

package main

import (
	"fmt"
	"github.com/spf13/cobra"
)

func main() {

	var startCmd = &cobra.Command{
		Use: "version",
		Short: "this is a test version",
		Long: "all application has a version",
		Run: func(cmd *cobra.Command, args []string) {
			fmt.Println("start -- HEAD",args)
		},
	}

	var versionCmd = &cobra.Command{
		Use: "version",
		Short: "this is a test version",
		Long: "all application has a version",
		Run: func(cmd *cobra.Command, args []string) {
			fmt.Println("version1.0 -- ",args)
		},
	}
	startCmd.AddCommand(versionCmd)
	_ = startCmd.Execute()
}
