# 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 Apache License 2.0. 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
|
||||
```
