validator

A lightweight model validator written in Go.

quickstart

package main

import (
	"fmt"
	v "github.com/go-the-way/validator"
)

func main() {
	result := v.New(&struct {
		int `validate:"min(10,fail)"`
	}{}).Validate()
	fmt.Println(result.Passed)
	fmt.Println(result.Messages())
}

Custom validation implementation

package main

import (
	"fmt"
	v "github.com/go-the-way/validator"
	"reflect"
)

func main() {
	v.Custom("mycustom", func(value reflect.Value) (bool, string) { return false, "mycustom validation." })
	vv := v.New(&struct {
		Name string `validate:"custom(mycustom)"`
	}{}).Validate()
	fmt.Println(vv.Passed)
	fmt.Println(vv.Messages())
}
