	// Here you will define your flags and configuration settings.

	// Cobra supports Persistent Flags which will work for this command
	// and all subcommands, e.g.:
	// showtagsCmd.PersistentFlags().String("foo", "", "A help for foo")

	// Cobra supports local flags which will only run when this command
	// is called directly, e.g.:
	tagShowCmd.Flags().BoolP("indent", "i", false, "indent the json data")
	tagShowCmd.Flags().StringVarP(&regex, "regex", "r", "", "regex")
