Functions

func Join

func Join(base map[string]string, override map[string]string) map[string]string

Join joins the two environment maps with override overriding base.

func ParseFile

func ParseFile(path string) (_ map[string]string, err error)

ParseFile parses the specified path for environment variables and returns them as a map.

func ParseSlice

func ParseSlice(s []string) (map[string]string, error)

ParseSlice parses the specified slice and transforms it into an environment map.

func Slice

func Slice(m map[string]string) []string

Slice transforms the specified map of environment variables into a slice. If a value is non-empty, the key and value are joined with '='.
