Functions

func Clear

func Clear()

func Expand

func Expand(data string) string

Expand replaces ${var} or $var in the string according to the values of the current environment variables. References to undefined variables are replaced by the empty string.

func ExpandEnv

func ExpandEnv(value string) string

ExpandEnv returns value of convert with environment variable. Return environment variable if value start with "${" and end with "}". Return default value if environment variable is empty or not exist.

It accept value formats "${env}" , "${env||}}" , "${env||defaultValue}" , "defaultvalue". Examples:

v1 := config.ExpandValueEnv("${GOPATH}")			// return the GOPATH environment variable.
v2 := config.ExpandValueEnv("${GOAsta||/usr/local/go}")	// return the default value "/usr/local/go/".
v3 := config.ExpandValueEnv("Astaxie")				// return the value "Astaxie".
