Functions

func Get

func Get(key, defaultValue string) string

Get returns the trimmed value of the environment variable named by key. If the variable is unset or empty after trimming, defaultValue is returned.

func GetBool

func GetBool(key string, defaultValue bool) bool

GetBool returns the boolean value of the environment variable named by key. Recognizes true/false, 1/0, t/f, yes/no (case-insensitive). If the variable is unset or unrecognized, defaultValue is returned.

func GetInt

func GetInt(key string, defaultValue int) int

GetInt returns the integer value of the environment variable named by key. If the variable is unset or unparsable, defaultValue is returned. Values like "50abc" are rejected (unlike fmt.Sscanf which parses the prefix).
