+# Structs [![GoDoc](http://img.shields.io/badge/go-documentation-blue.svg?style=flat-square)](http://godoc.org/github.com/fatih/structs) [![Build Status](http://img.shields.io/travis/fatih/structs.svg?style=flat-square)](https://travis-ci.org/fatih/structs) [![Coverage Status](http://img.shields.io/coveralls/fatih/structs.svg?style=flat-square)](https://coveralls.io/r/fatih/structs)
+
+Structs contains various utilities to work with Go (Golang) structs. It was
+initially used by me to convert a struct into a `map[string]interface{}`. With
+time I've added other utilities for structs. It's basically a high level
+package based on primitives from the reflect package. Feel free to add new
+functions or improve the existing code.
+
+## Install
+
+```bash
+go get github.com/fatih/structs
+```
+
+## Usage and Examples
+
+Just like the standard lib `strings`, `bytes` and co packages, `structs` has
+many global functions to manipulate or organize your struct data. Lets define
+and declare a struct:
+
+```go
+type Server struct {
+ Name string `json:"name,omitempty"`
+ ID int
+ Enabled bool
+ users []string // not exported
+ http.Server // embedded
+}
+
+server := &Server{
+ Name: "gopher",
+ ID: 123456,
+ Enabled: true,
+}
+```
+
+```go
+// Convert a struct to a map[string]interface{}
+// => {"Name":"gopher", "ID":123456, "Enabled":true}
+m := structs.Map(server)
+
+// Convert the values of a struct to a []interface{}
+// => ["gopher", 123456, true]
+v := structs.Values(server)
+
+// Convert the names of a struct to a []string
+// (see "Names methods" for more info about fields)
+n := structs.Names(server)
+
+// Convert the values of a struct to a []*Field
+// (see "Field methods" for more info about fields)
+f := structs.Fields(server)
+
+// Return the struct name => "Server"
+n := structs.Name(server)
+
+// Check if any field of a struct is initialized or not.
+h := structs.HasZero(server)
+
+// Check if all fields of a struct is initialized or not.
+z := structs.IsZero(server)
+
+// Check if server is a struct or a pointer to struct
+i := structs.IsStruct(server)
+```
+
+### Struct methods
+
+The structs functions can be also used as independent methods by creating a new
+`*structs.Struct`. This is handy if you want to have more control over the
+structs (such as retrieving a single Field).
+
+```go
+// Create a new struct type:
+s := structs.New(server)
+
+m := s.Map() // Get a map[string]interface{}
+v := s.Values() // Get a []interface{}
+f := s.Fields() // Get a []*Field
+n := s.Names() // Get a []string
+f := s.Field(name) // Get a *Field based on the given field name
+f, ok := s.FieldOk(name) // Get a *Field based on the given field name
+n := s.Name() // Get the struct name
+h := s.HasZero() // Check if any field is uninitialized
+z := s.IsZero() // Check if all fields are uninitialized
+```
+
+### Field methods
+
+We can easily examine a single Field for more detail. Below you can see how we
+get and interact with various field methods:
+
+
+```go
+s := structs.New(server)
+
+// Get the Field struct for the "Name" field
+name := s.Field("Name")
+
+// Get the underlying value, value => "gopher"
+value := name.Value().(string)
+
+// Set the field's value
+name.Set("another gopher")
+
+// Get the field's kind, kind => "string"
+name.Kind()
+
+// Check if the field is exported or not
+if name.IsExported() {
+ fmt.Println("Name field is exported")
+}
+
+// Check if the value is a zero value, such as "" for string, 0 for int
+if !name.IsZero() {
+ fmt.Println("Name is initialized")
+}
+
+// Check if the field is an anonymous (embedded) field
+if !name.IsEmbedded() {
+ fmt.Println("Name is not an embedded field")
+}
+
+// Get the Field's tag value for tag name "json", tag value => "name,omitempty"
+tagValue := name.Tag("json")
+```
+
+Nested structs are supported too:
+
+```go
+addrField := s.Field("Server").Field("Addr")
+
+// Get the value for addr
+a := addrField.Value().(string)
+
+// Or get all fields
+httpServer := s.Field("Server").Fields()
+```
+
+We can also get a slice of Fields from the Struct type to iterate over all
+fields. This is handy if you wish to examine all fields:
+
+```go
+s := structs.New(server)
+
+for _, f := range s.Fields() {
+ fmt.Printf("field name: %+v\n", f.Name())
+
+ if f.IsExported() {
+ fmt.Printf("value : %+v\n", f.Value())
+ fmt.Printf("is zero : %+v\n", f.IsZero())
+ }
+}
+```

+# YAML marshaling and unmarshaling support for Go
+
+[![Build Status](https://travis-ci.org/ghodss/yaml.svg)](https://travis-ci.org/ghodss/yaml)
+
+## Introduction
+
+A wrapper around [go-yaml](https://github.com/go-yaml/yaml) designed to enable a better way of handling YAML when marshaling to and from structs.
+
+In short, this library first converts YAML to JSON using go-yaml and then uses `json.Marshal` and `json.Unmarshal` to convert to or from the struct. This means that it effectively reuses the JSON struct tags as well as the custom JSON methods `MarshalJSON` and `UnmarshalJSON` unlike go-yaml. For a detailed overview of the rationale behind this method, [see this blog post](http://ghodss.com/2014/the-right-way-to-handle-yaml-in-golang/).
+
+## Compatibility
+
+This package uses [go-yaml](https://github.com/go-yaml/yaml) and therefore supports [everything go-yaml supports](https://github.com/go-yaml/yaml#compatibility).
+
+## Caveats
+
+**Caveat #1:** When using `yaml.Marshal` and `yaml.Unmarshal`, binary data should NOT be preceded with the `!!binary` YAML tag. If you do, go-yaml will convert the binary data from base64 to native binary data, which is not compatible with JSON. You can still use binary in your YAML files though - just store them without the `!!binary` tag and decode the base64 in your code (e.g. in the custom JSON methods `MarshalJSON` and `UnmarshalJSON`). This also has the benefit that your YAML and your JSON binary data will be decoded exactly the same way. As an example:
+
+```
+BAD:
+ exampleKey: !!binary gIGC
+
+GOOD:
+ exampleKey: gIGC
+... and decode the base64 data in your code.
+```
+
+**Caveat #2:** When using `YAMLToJSON` directly, maps with keys that are maps will result in an error since this is not supported by JSON. This error will occur in `Unmarshal` as well since you can't unmarshal map keys anyways since struct fields can't be keys.
+
+## Installation and usage
+
+To install, run:
+
+```
+$ go get github.com/ghodss/yaml
+```
+
+And import using:
+
+```
+import "github.com/ghodss/yaml"
+```
+
+Usage is very similar to the JSON library:
+
+```go
+package main
+
+import (
+ "fmt"
+
+ "github.com/ghodss/yaml"
+)
+
+type Person struct {
+ Name string `json:"name"` // Affects YAML field names too.
+ Age int `json:"age"`
+}
+
+func main() {
+ // Marshal a Person struct to YAML.
+ p := Person{"John", 30}
+ y, err := yaml.Marshal(p)
+ if err != nil {
+ fmt.Printf("err: %v\n", err)
+ return
+ }
+ fmt.Println(string(y))
+ /* Output:
+ age: 30
+ name: John
+ */
+
+ // Unmarshal the YAML back into a Person struct.
+ var p2 Person
+ err = yaml.Unmarshal(y, &p2)
+ if err != nil {
+ fmt.Printf("err: %v\n", err)
+ return
+ }
+ fmt.Println(p2)
+ /* Output:
+ {John 30}
+ */
+}
+```
+
+`yaml.YAMLToJSON` and `yaml.JSONToYAML` methods are also available:
+
+```go
+package main
+
+import (
+ "fmt"
+
+ "github.com/ghodss/yaml"
+)
+
+func main() {
+ j := []byte(`{"name": "John", "age": 30}`)
+ y, err := yaml.JSONToYAML(j)
+ if err != nil {
+ fmt.Printf("err: %v\n", err)
+ return
+ }
+ fmt.Println(string(y))
+ /* Output:
+ name: John
+ age: 30
+ */
+ j2, err := yaml.YAMLToJSON(y)
+ if err != nil {
+ fmt.Printf("err: %v\n", err)
+ return
+ }
+ fmt.Println(string(j2))
+ /* Output:
+ {"age":30,"name":"John"}
+ */
+}
+```
