# YAML support for the Go language

Introduction
------------

The yaml package enables Go programs to comfortably encode and decode YAML
values. It was developed within [Canonical](https://www.canonical.com) as
part of the [juju](https://juju.ubuntu.com) project, and is based on a
pure Go port of the well-known [libyaml](http://pyyaml.org/wiki/LibYAML)
C library to parse and generate YAML data quickly and reliably.

Compatibility
-------------

The yaml package supports most of YAML 1.1 and 1.2, including support for
anchors, tags, map merging, etc. Multi-document unmarshalling is not yet
implemented, and base-60 floats from YAML 1.1 are purposefully not
supported since they're a poor design and are gone in YAML 1.2.

Installation and usage
----------------------

The import path for the package is *gopkg.in/yaml.v2*.

To install it, run:

go get gopkg.in/yaml.v2

API documentation
-----------------

If opened in a browser, the import path itself leads to the API documentation:

* [https://gopkg.in/yaml.v2](https://gopkg.in/yaml.v2)

API stability
-------------

The package API for yaml v2 will remain stable as described in [gopkg.in](https://gopkg.in).

License
-------

The yaml package is licensed under the LGPL with an exception that allows it to be linked statically. Please see the LICENSE file for details.

Example
-------

```Go
package main

import (
"fmt"
"log"

"gopkg.in/yaml.v2"
)

var data = `
a: Easy!
b:
c: 2
d: [3, 4]
`

type T struct {
A string
B struct {
RenamedC int `yaml:"c"`
D []int `yaml:",flow"`
}
}

func main() {
t := T{}

err := yaml.Unmarshal([]byte(data), &t)
if err != nil {
log.Fatalf("error: %v", err)
}
fmt.Printf("--- t:\n%v\n\n", t)

d, err := yaml.Marshal(&t)
if err != nil {
log.Fatalf("error: %v", err)
}
fmt.Printf("--- t dump:\n%s\n\n", string(d))

m := make(map[interface{}]interface{})

err = yaml.Unmarshal([]byte(data), &m)
if err != nil {
log.Fatalf("error: %v", err)
}
fmt.Printf("--- m:\n%v\n\n", m)

d, err = yaml.Marshal(&m)
if err != nil {
log.Fatalf("error: %v", err)
}
fmt.Printf("--- m dump:\n%s\n\n", string(d))
}
```

This example will generate the following output:

```
--- t:
{Easy! {2 [3 4]}}

--- t dump:
a: Easy!
b:
c: 2
d: [3, 4]

--- m:
map[a:Easy! b:map[c:2 d:[3 4]]]

--- m dump:
a: Easy!
b:
c: 2
d:
- 3
- 4
```
