# go-yaml fork
This package is a fork of the go-yaml library and is intended solely for consumption
by kubernetes projects. In this fork, we plan to support only critical changes required for
kubernetes, such as small bug fixes and regressions. Larger, general-purpose feature requests
should be made in the upstream go-yaml library, and we will reject such changes in this fork
unless we are pulling them from upstream.
This fork is based on v2.4.0: https://github.com/go-yaml/yaml/releases/tag/v2.4.0
# 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]
`
// Note: struct fields must be public in order for unmarshal to
// correctly populate the data.
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
```

// Marshal serializes the value provided into a YAML document. The structure
// of the generated document will reflect the structure of the value itself.
// Maps and pointers (to struct, string, int, etc) are accepted as the in value.
//
// Struct fields are only marshalled if they are exported (have an upper case
// first letter), and are marshalled using the field name lowercased as the
// default key. Custom keys may be defined via the "yaml" name in the field
// tag: the content preceding the first comma is used as the key, and the
// following comma-separated options are used to tweak the marshalling process.
// Conflicting names result in a runtime error.
//
// The field tag format accepted is:
//
// `(...) yaml:"[<key>][,<flag1>[,<flag2>]]" (...)`
//
// The following flags are currently supported:
//
// omitempty Only include the field if it's not set to the zero
// value for the type or to empty slices or maps.
// Zero valued structs will be omitted if all their public
// fields are zero, unless they implement an IsZero
// method (see the IsZeroer interface type), in which
// case the field will be excluded if IsZero returns true.
//
// flow Marshal using a flow style (useful for structs,
// sequences and maps).
//
// inline Inline the field, which must be a struct or a map,
// causing all of its fields or keys to be processed as if
// they were part of the outer struct. For maps, keys must
// not conflict with the yaml keys of other struct fields.
//
// In addition, if the key is "-", the field is ignored.
//
// For example:
//
// type T struct {
// F int `yaml:"a,omitempty"`
// B int
// }
// yaml.Marshal(&T{B: 2}) // Returns "b: 2\n"
// yaml.Marshal(&T{F: 1}} // Returns "a: 1\nb: 0\n"
