A very simple validation framework that is not dependent on any other web/http framework.

Example

package main

import (
  "fmt"
  "github.com/kdar/validation"
)

func main() {
  v := validation.New()
  v.Add("test", validation.Numeric, "Test was not a numeric.")

  data := map[string]string{
    "test": "5",
  }

  valid, messages := v.Validate(data)
  fmt.Printf("%#v: %#v\n", data, valid)
  fmt.Println(messages)

  data["test"] = "hello"

  valid, messages = v.Validate(data)
  fmt.Printf("%#v: %#v\n", data, valid)
  fmt.Println(messages)
}
