	"go.krak3n.codes/gofig"
	"go.krak3n.codes/gofig/parsers/json"
)

type Config struct {
	Foo  string `gofig:"foo"`
	Bar  int    `gofig:"bar"`
	Fizz struct {
		Buzz string `gofig:"buzz"`
	} `gofig:"fizz"`
}

const blob = `{
	"foo": "bar",
	"bar": 12,
	"fizz": {
		"buzz": "fizz"
	}
}`

func main() {
	var cfg Config

	// Initialise gofig with the struct config values will be placed into
	gfg, err := gofig.New(&cfg)
	gofig.Must(err)

	// Parse
	gofig.Must(gfg.Parse(gofig.FromString(json.New(), blob)))

	fmt.Println(fmt.Sprintf("%+v", cfg))
