Functions

func Parse 

func Parse(env []string) (map[string]string, error)

Parse parses a list of environment variables of the form key=value into a map from keys to values. If a key appears multiple times, the last value of the key is returned.

Example 
vars, err := Parse([]string{
	"name=alice",
	"pet=cat",
	"name=bob", // bob overwrites alice
})
if err != nil {
	panic(err)
}
fmt.Println(vars["name"])
fmt.Println(vars["pet"])

Output:

bob
cat

func Split 

func Split(kv string) (string, string, error)

Split splits an environment variable of the form key=value into its constituent key and value parts.

Example 
key, value, err := Split("name=ava")
if err != nil {
	panic(err)
}
fmt.Println(key)
fmt.Println(value)

Output:

name
ava
