import (
	"github.com/phamtai97/go-utils/utils/config"
	"github.com/phamtai97/go-utils/utils/logger"
	"go.uber.org/zap"
)

// ServiceConfig config to test
type ServiceConfig struct {
	Bootstrap  BootstrapConfig
	Datasource DataSourceConfig
}

// BootstrapConfig config to test
type BootstrapConfig struct {
	Env            string
	Token          string
	Password       []string
	WorkerPoolSize int  `yaml:"workerPoolSize"`
	EnabledJob     bool `yaml:"enabledJob"`
}

// DataSourceConfig config to test
type DataSourceConfig struct {
	AccountDS DatabaseConfig `yaml:"accountDS"`
	SystemDS  DatabaseConfig `yaml:"systemDS"`
}

// DatabaseConfig config to test
type DatabaseConfig struct {
	Host      string
	Port      int
	Username  string
	Password  string
	TableName []string `yaml:"tableName"`
}

func main() {
	logger.InitProduction("")
	serviceConfig := ServiceConfig{}

	// We can provide path of config by flag to load config
	// config.LoadByFlag(&serviceConfig, "cfgPath")
	if err := config.Load(&serviceConfig, "dev.yaml"); err != nil {
		logger.Fatal("Failed to load config", zap.Error(err))
	}

	// Load config from json file
	// if err := config.Load(&serviceConfig, "dev.json"); err != nil {
	// 	logger.Fatal("Failed to load config", zap.Error(err))
	// }

	if err := config.Print(serviceConfig, "Token", "Password"); err != nil {
		logger.Fatal("Failed to print config", zap.Error(err))
	}
}
