Functions

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 NewEnvSpace

func NewEnvSpace(prefix string) *std_viper.Viper

NewEnvSpace returns an initialized Viper instance configured to read all keys from an environment variable prefix.

func ReadInConfig

func ReadInConfig(v *std_viper.Viper, configPath string) (err error)

ReadInConfig wraps viper.ReadInConfig to resolve relative paths, auto-detect the file type, etc.
