Functions ¶

func CurrentPackage ¶

func CurrentPackage() string

func Environ ¶

func Environ() []string

func Get ¶

func Get(key string, value string) string

Get a value from the ENV. If it doesn't exist the default value will be returned.

func GoPath ¶

func GoPath() string

func GoPaths ¶

func GoPaths() []string

GoPaths returns all possible GOPATHS that are set.

func Load ¶

func Load(files ...string) error

Load .env files. Files will be loaded in the same order that are received. Redefined vars will override previously existing values. IE: envy.Load(".env", "test_env/.env") will result in DIR=test_env If no arg passed, it will try to load a .env file.

func Map ¶

func Map() map[string]string

Map all of the keys/values set in envy.

func MustGet ¶

func MustGet(key string) (string, error)

Get a value from the ENV. If it doesn't exist an error will be returned

func MustSet ¶

func MustSet(key string, value string) error

MustSet the value into the underlying ENV, as well as envy. This may return an error if there is a problem setting the underlying ENV value.

func Reload ¶

func Reload()

Reload the ENV variables. Useful if an external ENV manager has been used

func Set ¶

func Set(key string, value string)

Set a value into the ENV. This is NOT permanent. It will only affect values accessed through envy.

func Temp ¶

func Temp(f func())

Temp makes a copy of the values and allows operation on those values temporarily during the run of the function. At the end of the function run the copy is discarded and the original values are replaced. This is useful for testing.
