Functions

func CensorSecretItem 

func CensorSecretItem(key string, value interface{}) interface{}

CensorSecretItem returns the censored item value with secrets and password removed for safe external use.

func DefaultPaths 

func DefaultPaths() []string

DefaultPaths returns the default paths used to search for config files.

func Dump 

func Dump(config Config) map[string]interface{}

Dump return a copy of the whole configuration, with secrets retracted. secret is any key containing "key", "secret", "password" or "passwd".

func Load 

func Load(withDefault bool, loadEnviron bool, paths ...string) (Config, []Item, prometheus.MultiError, error)

Load the configuration from files and environment variables. It returns the config, the loaded items, warnings and an error.

func ParseBool 

func ParseBool(value string) (bool, error)

ParseBool works like strconv.ParseBool but also supports "yes" and "no".
