Cobra 的简单使用

[root@localhost src]# mkdir /home/ailsa/gowork/src/agenda
mkdir: cannot create directory ‘/home/ailsa/gowork/src/agenda’: File exists
[root@localhost src]# cd agenda
[root@localhost agenda]# cobra init --pkg-name=agenda
Your Cobra applicaton is ready at
/home/ailsa/gowork/src/agenda
[root@localhost agenda]# cobra add register
register created at /home/ailsa/gowork/src/agenda
[root@localhost agenda]# ls
cmd  LICENSE  main.go
[root@localhost agenda]# cd cmd
[root@localhost cmd]# gedit register.go
[root@localhost cmd]# cd ..
[root@localhost agenda]# go run main.go register --user=TestUser
register called
register called by TestUser

测试添加子命令的用法：
add son command:

testson:
cobra add test
cobra add testson

cd cmd
gedit tryson.go
//tryCmd.AddCommand(trysonCmd)

cd ..
go run main.go test
go run main.go test testson

参数的用法：

tryCmd.Flags().StringP("try","t","-t","try something unkown")

修改try.go的Run函数，获取参数值

	Run: func(cmd *cobra.Command, args []string){
		str1,_ := cmd.Flags().GetString("try")
		fmt.Println(str1)
		fmt.Println("try called")
	},

获取两个参数值
Run函数

	Run: func(cmd *cobra.Command, args []string){
		str1,_ := cmd.Flags().GetString("try")
		fmt.Println(str1)
		str2,_ := cmd.Flags().GetString("try2")
		fmt.Println(str2)
		fmt.Println("try called")
	},

init函数

	rootCmd.AddCommand(tryCmd)
	tryCmd.Flags().StringP("try","t","","try something unkown")
	tryCmd.Flags().StringP("try2","y","","try2 something unkown")
