// This example shows how to load a configuration and then dump the resulting YAML.

package main

import (
	"fmt"
	"os"

	"github.com/openshift-online/ocm-sdk-go/configuration"
)

func main() {
	// Create the configuration and load all the files given in the command line:
	builder := configuration.New()
	args := os.Args[1:]
	if len(args) > 0 {
		for _, arg := range args {
			builder.Load(arg)
		}
	} else {
		builder.Load(os.Stdin)
	}
	object, err := builder.Build()
	if err != nil {
		fmt.Fprintf(os.Stderr, "Can't load configuration: %v\n", err)
		os.Exit(1)
	}

	// Dump the resulting YAML file:
	effective, err := object.Effective()
	if err != nil {
		fmt.Fprintf(os.Stderr, "Can't generate effective configuration: %v\n", err)
		os.Exit(1)
	}
	_, err = os.Stdout.Write(effective)
