env
Implements a simple way of handling environment values. Each environment field is simply reflected by a
variable inside the Go program. Out of the box handlers for the types bool
, []byte
, time.Duration
,
int
, []int
, string
and []string
are provided. Other types can be added by using
the RegisterField
function.
Example
var (
name = env.String("NAME", "joe")
age = env.Int("AGE", 24)
)
func main() {
env.ParseFlags()
fmt.Printf("%s is %d years old\n", name.Get(), age.Get())
}
If the program is called with -print short-bash
, all registered environment fields would be printed...
NAME="joe"
AGE="24"
By using -print long-bash
, a description for each field is generated.
# String field. The default value is 'joe'.
NAME="joe"
# Int field. The default value is '24'.
AGE="24"
