Functions

func Parse added in v1.0.6

func Parse(v interface{}) error

Parse parses a struct containing `env` tags and loads its values from environment variables.

Example
type config struct {
	Home         string `env:"HOME"`
	Port         int    `env:"PORT" envDefault:"3000"`
	IsProduction bool   `env:"PRODUCTION"`
}
os.Setenv("HOME", "/tmp/fakehome")
cfg := config{}
Parse(&cfg)
fmt.Println(cfg)
Output:

{/tmp/fakehome 3000 false}
