GitHub - xiaoxin01/typeregistry: create type dynamically in Golang (original) (raw)

a library to create type dynamically

how to use

// 1. define struct type Student struct { Age int Name string }

// 2. add reflect type key := AddType(new(Student))

// 3. create struct from registed key student := Make(key)

custom registed key

var i interface{} = new(Student)

// use lowercase struct name as key name := AddTypeWithKey(i, func(i interface{}) string { tpe := reflect.TypeOf(i).Elem() return strings.ToLower(tpe.Name()) })

student, ok := Create("student").(*Student)
