func IsSet

func IsSet(key string) bool

IsSet returns if the given env key is set.

func List

func List(prefix string) (envs []string)

func LockSetEnv

func LockSetEnv() func()

LockSetEnv locks modifications to environment. Call returned function to unlock.

func LookupEnv

func LookupEnv(key string) (string, string, string, error)

Additionally if the input is env://username:password@remote:port/ to fetch ENV values for the env value from a remote server. In this case, it also returns the credentials username and password

func RegisterGlobalCAs

func RegisterGlobalCAs(CAs *x509.CertPool)

RegisterGlobalCAs register the global root CAs

func SetEnvOff

func SetEnvOff()

SetEnvOff - turns off env lookup A global lock above this MUST ensure that

func SetEnvOn

func SetEnvOn()

SetEnvOn - turns on env lookup
