The yaml package enables Go programs to comfortably encode and decode YAML values. It was developed within Canonical as part of the juju project, and is based on a pure Go port of the well-known libyaml C library to parse and generate YAML data quickly and reliably.
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.
The import path for the package is gopkg.in/yaml.v2.
To install it, run:
go get gopkg.in/yaml.v2
If opened in a browser, the import path itself leads to the API documentation:
The package API for yaml v2 will remain stable as described in gopkg.in.
The yaml package is licensed under the Apache License 2.0. Please see the LICENSE file for details.
Some more examples can be found in the “examples” folder.
age main
rt (
"fmt"
"log"
"gopkg.in/yaml.v2"
data = `
asy!
2
[3, 4]
T struct {
A string
B struct {
RenamedC int `yaml:"c"`
D []int `yaml:",flow"`
}
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:
y! {2 [3 4]}}
t dump:
asy!
2
[3, 4]
m:
a:Easy! b:map[c:2 d:[3 4]]]
m dump:
asy!
