-# YAML marshaling and unmarshaling support for Go
-
-[![Build Status](https://travis-ci.org/ghodss/yaml.svg)](https://travis-ci.org/ghodss/yaml)
-
-## Introduction
-
-A wrapper around [go-yaml](https://github.com/go-yaml/yaml) designed to enable a better way of handling YAML when marshaling to and from structs.
-
-In short, this library first converts YAML to JSON using go-yaml and then uses `json.Marshal` and `json.Unmarshal` to convert to or from the struct. This means that it effectively reuses the JSON struct tags as well as the custom JSON methods `MarshalJSON` and `UnmarshalJSON` unlike go-yaml. For a detailed overview of the rationale behind this method, [see this blog post](http://ghodss.com/2014/the-right-way-to-handle-yaml-in-golang/).
-
-## Compatibility
-
-This package uses [go-yaml v2](https://github.com/go-yaml/yaml) and therefore supports [everything go-yaml supports](https://github.com/go-yaml/yaml#compatibility).
-
-## Caveats
-
-**Caveat #1:** When using `yaml.Marshal` and `yaml.Unmarshal`, binary data should NOT be preceded with the `!!binary` YAML tag. If you do, go-yaml will convert the binary data from base64 to native binary data, which is not compatible with JSON. You can still use binary in your YAML files though - just store them without the `!!binary` tag and decode the base64 in your code (e.g. in the custom JSON methods `MarshalJSON` and `UnmarshalJSON`). This also has the benefit that your YAML and your JSON binary data will be decoded exactly the same way. As an example:
-
-```
-BAD:
- exampleKey: !!binary gIGC
-
-GOOD:
- exampleKey: gIGC
-... and decode the base64 data in your code.
-```
-
-**Caveat #2:** When using `YAMLToJSON` directly, maps with keys that are maps will result in an error since this is not supported by JSON. This error will occur in `Unmarshal` as well since you can't unmarshal map keys anyways since struct fields can't be keys.
-
-## Installation and usage
-
-To install, run:
-
-```
-$ go get github.com/ghodss/yaml
-```
-
-And import using:
-
-```
-import "github.com/ghodss/yaml"
-```
-
-Usage is very similar to the JSON library:
-
-```go
-import (
- "fmt"
-
- "github.com/ghodss/yaml"
-)
-
-type Person struct {
- Name string `json:"name"` // Affects YAML field names too.
- Age int `json:"name"`
-}
-
-func main() {
- // Marshal a Person struct to YAML.
- p := Person{"John", 30}
- y, err := yaml.Marshal(p)
- if err != nil {
- fmt.Printf("err: %v\n", err)
- return
- }
- fmt.Println(string(y))
- /* Output:
- name: John
- age: 30
- */
-
- // Unmarshal the YAML back into a Person struct.
- var p2 Person
- err := yaml.Unmarshal(y, &p2)
- if err != nil {
- fmt.Printf("err: %v\n", err)
- return
- }
- fmt.Println(p2)
- /* Output:
- {John 30}
- */
-}
-```
-
-`yaml.YAMLToJSON` and `yaml.JSONToYAML` methods are also available:
-
-```go
-import (
- "fmt"
-
- "github.com/ghodss/yaml"
-)
-func main() {
- j := []byte(`{"name": "John", "age": 30}`)
- y, err := yaml.JSONToYAML(j)
- if err != nil {
- fmt.Printf("err: %v\n", err)
- return
- }
- fmt.Println(string(y))
- /* Output:
- name: John
- age: 30
- */
- j2, err := yaml.YAMLToJSON(y)
- if err != nil {
- fmt.Printf("err: %v\n", err)
- return
- }
- fmt.Println(string(j2))
- /* Output:
- {"age":30,"name":"John"}
- */
-}
-```
