omg.jsonParser is a simple JSON parser with a simple condition validation. It's a wrapper on standard go JSON lib. With it help you can add the validation condition via golang structure fields tags.
## Example
```go
package main
import (
"fmt"
"github.com/dedalqq/omg.jsonparser"
)
func main() {
jsonData := `{"name": ""}`
st := struct {
Name string `json:"name,notEmpty"` // added notEmpty for enable validation for it field
}{}
err := jsonparser.Unmarshal([]byte(jsonData), &st)
if err != nil {
fmt.Println(err.Error()) // print: value [name] must be not empty
}
}
```
## Tag struct
```
json:"[name][,option]..."
```
### Tag examples
Here are some the tag examples:
```go
package main
type data struct {
F1 string `json:"f1,notEmpty"` // the field must be not empty but can be "null" or may not exist
F2 string `json:"f2,notEmpty,required"` // the field is required and must be not empty but may be the "null" value
F3 string `json:"f3,notEmpty,notNull"` // the field must be not empty and not "null" but may not exist
F4 []string `json:"f4,notNull,min:3"` // the field must be not "null" and contains 3 or more items but may not exist
}
```
