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 initialized +z := s.IsZero() // Check if all fields are initialized +``` + +### 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()) + } +} +``` + +## Credits + + * [Fatih Arslan](https://github.com/fatih) + * [Cihangir Savas](https://github.com/cihangir) + +## License + +The MIT License (MIT) - see LICENSE.md for more details -- cgit v1.2.3
