新版本已经添加此功能

https://github.com/gookit/config/releases/tag/v2.1.4:

config/issues_test.go

Lines 234 to 255 in edd2db6

 func TestIssues_94(t *testing.T) { 

 is := assert.New(t) 

 // add option: config.ParseDefault 

 c := config.New("test").WithOptions(config.ParseDefault) 

 // only set name 

 c.SetData(map[string]interface{}{ 

 "name": "inhere", 

 }) 

 // age load from default tag 

 type User struct { 

 Age int `json:"age" default:"30"` 

 Name string 

 Tags []int 

 } 

 user := &User{} 

 is.NoErr(c.Decode(user)) 

 dump.Println(user) 

 is.Eq("inhere", user.Name) 

 is.Eq(30, user.Age)

from config.
