func EnvPrefixedName ¶

func EnvPrefixedName(prefix, key string) string

EnvPrefixedName replicates the private viper.mergeWithEnvPrefix.

func IsSetInCommand ¶

func IsSetInCommand(v *std_viper.Viper, c *cobra.Command, prefix, key string) bool

IsSetInCommand provides a viper.IsSet alternative that works around a bug which causes IsSet to always return true if the config key is bound to cobra: https://github.com/spf13/viper/issues/276.

The workaround logic doesn't support the case where a flag both has a default value and was also erroneously marked as required.

func MergeConfig ¶

func MergeConfig(fs *pflag.FlagSet, v *std_viper.Viper) (lastErr error)

MergeConfig supplements the one-way binding provided by viper.BindPFlag(s) which only allows reading the bound config values via viper, e.g. GetString, but not through variables bound to configs by cobra, e.g. via StringVarP(). This allows reading of the bound values from the latter.
