+## Features
+
+- validate value in `map[string]interface{}` by keys
+- validate data from `http.Request` json/multipart
+    - support file upload
+- enum value check
+- min/max length data check
+- email field check
+- uuid field check
+- IPv4 field check
+- IPv4 Network check
+- regex on string validation
+- custom message :
+    - on invalid regex message : ✅
+    - on null data message : ❌
+    - on max data message : ❌
+    - on type not match message : ❌
+    - on enum value not match : ❌
+
+## On Progress
+
+- validation for one data value only
+
+## Road Map
+
+- avoiding same value in some field
+    - ex case : `old_password` and `new_password`
+- get from urls params http
+- validation for `base64`
+- handle file size on multipart

 ## example :
 
 ### Example 1
-
 ```go
 payload := map[string]interface{}{"jenis_kelamin": "laki-laki", "hoby": "Main PS", "umur": 1, "menikah": true}
 err := map_validator.NewValidateBuilder().SetRules(map[string]map_validator.Rules{
-"jenis_kelamin": {Enum: &map_validator.EnumField[any]{Items: []string{"laki-laki", "perempuan"}}},
-"hoby":          {Type: reflect.String, Null: false},
-"menikah":       {Type: reflect.Bool, Null: false},
+    "jenis_kelamin": {Enum: &map_validator.EnumField[any]{Items: []string{"laki-laki", "perempuan"}}},
+    "hoby":          {Type: reflect.String, Null: false},
+    "menikah":       {Type: reflect.Bool, Null: false},
 }).Load(payload).RunValidate()
 if err != nil {
-t.Errorf("Expected not have error, but got error : %s", err)
+    t.Errorf("Expected not have error, but got error : %s", err)
 }
 
 err = map_validator.NewValidateBuilder().SetRules(map[string]map_validator.Rules{
-"jenis_kelamin": {Enum: &map_validator.EnumField[any]{Items: []string{"laki-laki", "perempuan"}}},
-"hoby":          {Type: reflect.Int, Null: false},
-"menikah":       {Type: reflect.Bool, Null: false},
+    "jenis_kelamin": {Enum: &map_validator.EnumField[any]{Items: []string{"laki-laki", "perempuan"}}},
+    "hoby":          {Type: reflect.Int, Null: false},
+    "menikah":       {Type: reflect.Bool, Null: false},
 }).Load(payload).RunValidate()
 if err == nil {
-t.Error("Expected have an error, but you got no error")
+    t.Error("Expected have an error, but you got no error")
 }
 ```
 
 ### Example Echo Framework
-
 ```go
 func handleLogin(c echo.Context) error {
-jsonHttp, err := map_validator.NewValidateBuilder().SetRules(map[string]map_validator.Rules{
-"email":    {Email: true, Max: map_validator.ToPointer[int](100)},
-"password": {Type: reflect.String, Min: map_validator.ToPointer[int](6), Max: map_validator.ToPointer[int](30)},
-}).LoadJsonHttp(c.Request())
-if err != nil {
-return c.JSON(http.StatusBadRequest, err)
-}
-err = jsonHttp.RunValidate()
-if err != nil {
-return c.JSON(http.StatusBadRequest, err)
-}
-return c.NoContent(http.StatusOK)
+    jsonHttp, err := map_validator.NewValidateBuilder().SetRules(map[string]map_validator.Rules{
+        "email":    {Email: true, Max: map_validator.ToPointer[int](100)},
+        "password": {Type: reflect.String, Min: map_validator.ToPointer[int](6), Max: map_validator.ToPointer[int](30)},
+    }).LoadJsonHttp(c.Request())
+    if err != nil {
+        return c.JSON(http.StatusBadRequest, err)
+    }
+    err = jsonHttp.RunValidate()
+    if err != nil {
+        return c.JSON(http.StatusBadRequest, err)
+    }
+    return c.NoContent(http.StatusOK)
 }
 
 func main() {
-e := echo.New()
-e.POST("/login", handleLogin)
-e.Start(":3000")
+    e := echo.New()
+    e.POST("/login", handleLogin)
+    e.Start(":3000")
 }
 
 ```
 
 ### Example Bind To Struct
-
 ```go
 type Data struct {
-JK      string `map_validator:"jenis_kelamin"`
-Hoby    string `map_validator:"hoby"`
-Menikah bool   `map_validator:"menikah"`
+    JK      string `map_validator:"jenis_kelamin"`
+    Hoby    string `map_validator:"hoby"`
+    Menikah bool   `map_validator:"menikah"`
 }
 
 payload := map[string]interface{}{"jenis_kelamin": "laki-laki", "hoby": "Main PS", "umur": 1, "menikah": true}
 err := map_validator.NewValidateBuilder().SetRules(map[string]map_validator.Rules{
-"jenis_kelamin": {Enum: &map_validator.EnumField[any]{Items: []string{"laki-laki", "perempuan"}}},
-"hoby":          {Type: reflect.String, Null: false},
-"menikah":       {Type: reflect.Bool, Null: false},
+    "jenis_kelamin": {Enum: &map_validator.EnumField[any]{Items: []string{"laki-laki", "perempuan"}}},
+    "hoby":          {Type: reflect.String, Null: false},
+    "menikah":       {Type: reflect.Bool, Null: false},
 }).Load(payload).RunValidate()
 if err != nil {
-t.Errorf("Expected not have error, but got error : %s", err)
+    t.Errorf("Expected not have error, but got error : %s", err)
 }
 
 testBind := &Data{}
 if testBind.JK != "" {
-t.Errorf("Expected : '' But you got : %s", testBind.JK)
+    t.Errorf("Expected : '' But you got : %s", testBind.JK)
 }
 err = extraCheck.Bind(testBind)

+    t.Errorf("Expected : %s But you got : %s", payload["jenis_kelamin"], testBind.JK)
 }
