This is not passing. I'm still trying to figure out. @nrktkt

objekt is a Try and ex1 is an Example1. so the comparison fails

Suggested change

	val objekt = ex1json.to[Example1]
	objekt match {
	case Failure(e: DecodingFailure) => println(e.printStackTrace())
	}
	objekt shouldEqual ex1
	}
	val objekt = ex1json.to[Example1]
	objekt match {
	case Failure(e: DecodingFailure) => println(e.printStackTrace())
	}
	objekt.success.value shouldEqual ex1
	}

the Try is a Failure, i was trying to print the stacktrace.

It turns out that NinnyToCirce and CirceToNinny put toegher, is breaking Circe itself's decoding functionality,

i.e. a Circe json object's Decoder is implicitly converted to Ninny's FromJson, then implicitly converted to Decoder, over and over.

So I think it would be better to separate CirceToNinny and NinnyToCirce

E.g.

import CirceCompat._

case class Person(name: String, age: Int)
object Person {
  implicit val encoder = deriveEncoder[Person]
  implicit val decoder = deriveDecoder[Person]
}

val json = Person("alice", 30).asJson

// Decoder[Person] is implicitly converted to FromJson[Person] by CirceCompat
// then FromJson is converted to Decoder, so on so forth
json.to[Person]

maybe just add a nested object to these examples and then I think it looks good

added a nested Person
