TODO: should getEnv logic be moved into find(). Can generalize the use of rewriting keys many things, Ex: Get('someKey') -> some_key (camel case to snake case for JSON keys perhaps) getEnv is a wrapper around os.Getenv which replaces characters in the original key. This allows env vars which have di

(key string)

// key. This allows env vars which have different keys than the config object
// keys.
func (v *Viper) getEnv(key string) (string, bool) {
	if v.envKeyReplacer != nil {
		key = v.envKeyReplacer.Replace(key)
	}

	val, ok := os.LookupEnv(key)

	return val, ok && (v.allowEmptyEnv || val != "")
}

// ConfigFileUsed returns the file used to populate the config registry.
func ConfigFileUsed() string            { return v.ConfigFileUsed() }
