Add a feature to customize error messages

Would be great if there's an easy way to customize error messages.

Agreed, seeing "zero value" is fine for in-app cases I think, but for end-user programs such as a CLI it can be confusing

Any news?

You can try to do the following:

validator.ErrMin = validator.TextErr{Err: errors.New("my custom error string")}
err := validator.Valid(2, "min=10")

if err != nil {
	fmt.Println(err)
}

I think that is applicable for all other errors.
