If I must manually check the config viper got and set the flag of cmd?

[acehinnnqru]

I used cobra init --viper to initialize a project, https://github.com/acehinnnqru/gclone.

However, the config $HOME/.gclone.yaml doesn't work?
The ~/.gclone.yaml:

root: ~/path/to/my/repo

I need to manually get the value with viper.Get* and set it to my pFlag.

root.go is like this:

func init() {
	cobra.OnInitialize(initConfig)

	rootCmd.PersistentFlags().StringVar(&cfgFile, "config", "", "config file (default is $HOME/.gclone.yaml)")
	rootCmd.PersistentFlags().StringVarP(&repoRoot, "root", "r", "", "--root")
	cobra.CheckErr(viper.BindPFlag("root", rootCmd.PersistentFlags().Lookup("root")))
}

// initConfig reads in config file and ENV variables if set.
func initConfig() {
	viper.Debug()
	if cfgFile != "" {
		// Use config file from the flag.
		viper.SetConfigFile(cfgFile)
	} else {
		// Find home directory.
		home, err := os.UserHomeDir()
		cobra.CheckErr(err)

		// Search config in home directory with name ".gclone" (without extension).
		viper.AddConfigPath(home)
		viper.SetConfigType("yaml")
		viper.SetConfigName(".gclone")
	}

	viper.AutomaticEnv() // read in environment variables that match

	// If a config file is found, read it in.
	if err := viper.ReadInConfig(); err == nil {
		fmt.Fprintln(os.Stderr, "Using config file:", viper.ConfigFileUsed())
	}
}

I have tried to use viper.Debug, the pFlag of root is there, but the variable repoRoot is none.

OK, I know how to use it now.

I thought the variable var in cobra.Flags().StringPVar(&var,...) would be set automatically...
I got to know that I was wrong. Viper will automatically got the var but all var should be retrived through viper.Get*() manually.

Thanks, anyway.
