Go YAML

Simple example for serializing and deserializing structs with YAML:

// go get gopkg.in/yaml.v2


type Book struct {
	Title  string `yaml:"title"`
	Author string `yaml:"author"`
}

type Library struct {
	ID    int    `yaml:"id"`
	Name  string `yaml:"name"`
	Books []Book `yaml:"books"`
}

func objToYaml() {
	l := Library{
		ID:   1,
		Name: "The Library",
		Books: []Book{
			Book{Title: "First Book", Author: "First Author"},
			Book{Title: "Second Book", Author: "Second Author"},
		},
	}

	y, err := yaml.Marshal(l)
	if err != nil {
		log.Fatal(err.Error())
	}
	fmt.Println(string(y))
}

func yamlToObj() {
	y := `id: 1
name: The Library
books:
- title: First Book
  author: First Author
- title: Second Book
  author: Second Author`

	var l Library
	err := yaml.Unmarshal([]byte(y), &l)
	if err != nil {
		log.Fatal(err.Error())
	}
	fmt.Printf("%#v\n", l)
}
