Hey
What is sjson style?
Sam Smoot
@sam
(typeclasses?)
eugene yokota
@eed3si9n
Stefan Ollinger
@dozed
Ah right, they have reflection and typeclasses
Sam Smoot
@sam
package services.json.formats

import services.schema.User
import User.Account
import services.schema.User
import spray.json._

object AccountFormat extends RootJsonFormat[Account] {

  import DefaultJsonProtocol._

  implicit val dateTimeFormat = DateTimeFormat

  val format = jsonFormat5(Account.apply)

  def read(value: JsValue) = format.read(value)

  def write(account: Account) = format.write(account)
}
Stefan Ollinger
@dozed
@eed3si9n There are the JSONW[A], JSONR[A] typeclasses in https://github.com/json4s/json4s/tree/3.4/scalaz
Sam Smoot
@sam
I don’t think I’ve seen spray-json use reflection. But I could’ve just missed it.
Stefan Ollinger
@dozed
I am currently working on it a bit here https://github.com/dozed/json4s-drafts
Sam Smoot
@sam
Oh… well, duh. I guess the jsonFormatN helpers must be reflection based.
Stefan Ollinger
@dozed
@sam I referred to sjson
They had two modes
Sam Smoot
@sam
Ah. I read ‘spray’ and confused myself. Nevermind me. :)
eugene yokota
@eed3si9n
yea. I should've been more clear
so it doesn't exist yet, but you guys are thinking about it?
Stefan Ollinger
@dozed
It exists, officially in form of https://github.com/json4s/json4s/tree/3.4/scalaz, but it needs some polishing
eugene yokota
@eed3si9n
i see, but I am guessing that it pulls in Scalaz as dependency
anyfoo. thanks for the info!
Stefan Ollinger
@dozed
Yep, the scalaz dependency might be a problem (dependency size, conflicts)

Pretty sure I just spotted a bug while browsing the code trying to point out why using json4s-native 3.3.x was an issue for another project: https://github.com/json4s/json4s/pull/339/files#r60582054
The fix is pretty trivial. I included code in my comment for it. Just didn’t feel like setting everything up, writing a failing spec and producing a PR. ;) Doesn’t impact me since I wouldn’t use the alwaysEncodeUnicode option anyways. But if you do, I’m fairly confident the invalid-json-control-character bug is still present in that case.

What's the name of the decoder typeclass I need to provide?

@malibuworkcrew
Hey json4s crew, love the library! Do you happen to have a planned release schedule for 3.4? We'd love to get the mutable parser feature.
Kazuhiro Sera
@seratch
@malibuworkcrew Indeed, it's about time to release 3.4. I'll work on it. Maybe this month.
Spencer Wood
@malibuworkcrew
Thanks Kaz! Looking forward to it

Hi, I’m wondering how to remove an item from a JArray by ordinal? ie: Extraction.decompose(List(“one”, “two”, “three”)).remove(1) == JArray(List(JString(“one”), JString(“three”)))
Sam Smoot
@sam
Figured it out:
photoDocument transformField {
   case ("comments", JArray(comments)) =>
     val (start, _ :: end) = comments.splitAt(1)
    ("comments", start ::: end)
}

Is it possible to parse a Json string to an object based on the value of one field?
Let's say you have 2 possible kinds of Json strings and depending on one field value it is one of the two kinds?
(I can of course use an if test but just curious if there is a nicer way)

Great, thank you for the hard work :+1:
Where can I find the release notes for 3.4?

Is it possible to escape/unescape a string with help of json4s ?
Oleg Yarin
@monapasan
anyone ?
Stefan Ollinger
@dozed
@monapasan Can you give an example what you are trying to do?
@seratch Thanks for releasing 3.4

Hi, I created a pull request to support new MongoDB Java Async driver, since they introduced some new types it's not possible to use the current mongodb support. If you have any remarks, suggestions or anything I can do to make it better, please let me know

Hey,Guys.Is there any way to use json4s in akka-http but without case class ?
```
scala> import org.json4s._
scala> import org.json4s.jackson.JsonMethods._

scala> implicit val formats = DefaultFormats // Brings in default date formats etc.


// I don’t want use case class here
scala> case class Child(name: String, age: Int, birthdate: Option[java.util.Date])
scala> case class Address(street: String, city: String)
scala> case class Person(name: String, address: Address, children: List[Child])

scala> val json = parse("""
         { "name": "joe",
           "address": {
             "street": "Bulevard",
             "city": "Helsinki"
           },
           "children": [
             {
               "name": "Mary",
               "age": 5,
               "birthdate": "2004-09-04T18:06:22Z"
             },
             {
               "name": "Mazy",
               "age": 3
             }
           ]
         }
