Check if a property is nullable

[discount-elf]

Is there simple way (via reflection or otherwise) to check if a property is nullable? .defaultValue returning null sort of works but is there a solid solution?

Yup! Here's how you'd do that:

import "pkl:reflect"

class Foo {
  required: String
  nullable: String?
}

propRequired = reflect.Class(Foo).properties["required"].type is reflect.NullableType
propNullable = reflect.Class(Foo).properties["nullable"].type is reflect.NullableType

Result:

propRequired = false
propNullable = true
