GetUint16 returns the value associated with the key as an unsigned integer.

GetUint32 returns the value associated with the key as an unsigned integer.

GetUint64 returns the value associated with the key as an unsigned integer.

GetViper gets the global Viper instance.

InConfig checks to see if the given key (or an alias) is in the config file.

IsSet checks to see if the key has been set in any of the data locations.

KeyDelimiter sets the delimiter used for determining key parts.

MergeConfig merges a new configuration with an existing config.

MergeConfigMap merges the configuration from the map given with an existing config.

MergeInConfig merges a new configuration with an existing config.

MustBindEnv wraps BindEnv in a panic.

New returns an initialized Viper instance.

NewWithOptions creates a new Viper instance.

OnConfigChange sets the event handler that is called when a config file changes.

ReadConfig will read a configuration file, setting existing keys to nil if the key does not exist in the file.

ReadInConfig will discover and load the configuration file from disk and key/value stores, searching in one of the defined paths.

RegisterAlias creates an alias that provides another accessor for the same key.

Reset is intended for testing, will reset all to default settings.

SafeWriteConfig writes current configuration to file only if the file does not exist.

SafeWriteConfigAs writes current configuration to a given filename if it does not exist.

Set sets the value for the key in the override register.

SetConfigFile explicitly defines the path, name and extension of the config file.

SetConfigName sets name for the config file.

SetConfigPermissions sets the permissions for the config file.

SetConfigType sets the type of the configuration returned by the remote source, e.g.

SetDefault sets the default value for this key.

SetEnvKeyReplacer sets the strings.Replacer on the viper object Useful for mapping an environmental variable to a key that does not match it.

SetEnvPrefix defines a prefix that ENVIRONMENT variables will use.

SetFs sets the filesystem to use to read configuration.

SetTypeByDefaultValue enables or disables the inference of a key value's type when the Get function is used based upon a key's default value as opposed to the value returned based on the normal fetch logic.

Sub returns new Viper instance representing a sub tree of this instance.

Unmarshal unmarshals the config into a Struct.

UnmarshalExact unmarshals the config into a Struct, erroring if a field is nonexistent in the destination struct.

UnmarshalKey takes a single key and unmarshals it into a Struct.

WatchConfig starts watching a config file for changes.

WithLogger sets a custom logger.

WriteConfig writes the current configuration to a file.
