How to extend validators

[ornolisvt]

I think that is a great library, but I would like to know how to implement a custom validator, for example, compare two fields for equality (password and repeat password)

Hi,
thank you for your interest in Kalidation.
Cross field validation is on the backlog for a future version of Kalidation.

In the meantime, you can use a function to validate the two password fields:

In your class:
fun validatePasswords(): Boolean = this.password == this.repeatPassword

And then in Kalidation

constraints<ClassWithMethods> {
    property(ClassWithMethods::xxxx) {
      ///
  }
    returnOf(ClassWithMethods::validatePasswords) {
        assertTrue()
  }

Hope this helps,.
Regards,
Richard
