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
