Functions

func ExpandEnv

func ExpandEnv(s string) string

ExpandEnv - like os.ExpandEnv, except supports `_FILE` vars as well

func Getenv

func Getenv(key string, def ...string) string

Getenv - retrieves the value of the environment variable named by the key. If the variable is unset, but the same variable ending in `_FILE` is set, the referenced file will be read into the value. Otherwise the provided default (or an emptry string) is returned.
