	"mae.earth/pkg/numcat/random"
	"fmt"
	"os"
)

const (
	TOTAL int = 100
)

func main() {

	/* read the catalogue */
	reader := catalogue.New()

	/* create a random tool */
	tool,err := random.New(reader)
	if err != nil {
		fmt.Fprintf(os.Stderr,"error creating random tool from catalogue -- %v\n",err)
		os.Exit(1)
	}

	for i := 0; i < TOTAL; i++ {
		
		n,err := tool.Normal()
		if err != nil {
			fmt.Fprintf(os.Stderr,"error requesting normal from random tool -- %v\n",err)
			os.Exit(2)
		}

		u,err := tool.Uniform()
		if err != nil {
			fmt.Fprintf(os.Stderr,"error requesting uniform from random tool -- %v\n",err)
			os.Exit(2)
		}

		fmt.Fprintf(os.Stdout,"%05d/%05d\t%f\t%f\n", i + 1, TOTAL, n, u)
	}
