is 0.6.2 for use with 1.2.70 only?

not tagged / released on github.. that confused me for a bit before

Ah, never mind, it’s just that the README isn’t updated yet.

decodeElementIndex

indeed produces element index. You need to switch over it and then select proper property to decode

Hello, I'm using Kotlin 1.2.71-release-IJ2018.2-1, IntellJ 2018.2.4 #IC-182.4505.22, with a Javascript project without Gradle, and I always get an error with the serialization plugin for IntelliJ when trying to compile my project. The direct link to the Latest release (1.2.70) in the github readme.md "doesn't work" and I tried installing different versions, 6.2, 6.1... but all of them are failing.

In particular I can't find

kotlinx-gradle-serialization-plugin:0.8.1-rc13

in the repos

How can we create a custom serializer?

Any thoughts or work to have this serializer plugged into retrofit2? Might be an interesting test case at least…

What is the current status of serialization+native+multiplatform? Is workaround for plugin path still required?

Hi. I cannot find any functions to use Reader/Writer (nor IOStream). Are they not available?

with serialization being part of kotlin 1.3, does that mean we can start using it in apps that ship soon?

JSON

{
  "data": [
    {
      "id": "x1_1",
      "type": "x1"
    },
    {
      "id": "x2_1",
      "type": "x2",
      "children": [
        {
          "id": "y1_1",
          "type": "y1"
        },
        {
          "id": "y2_1",
          "type": "y2",
          "connectedItems": [
            "x1_1"
          ]
        }      
    }
  ]
}

Data classes

interface X {
  val id: String
}

interface Y {
  val id: String
}

data class D1(data: Array<X>)

data class X1(id): X
data class X2(id, children: Array<Y>): X

data class Y1(id): Y
data class Y2(id, connectedItems): Y

If there any possibility to realize deserialization for this case (according

type

field)?

i have a annoying api where a timestamp can be a string or a long, is there a way to tell in the deserializer what JSON type a field is ? number literal or string literal or is ther tryParseLong() or similar ?

https://github.com/JetBrains/kotlinconf-app/blob/master/common/src/commonMain/kotlin/org/jetbrains/kotlinconf/api/KotlinConfApi.kt#L16 seeing the Sourcecode of the KotlinxSerializer it does not support List<Whatever>::class as mapping argument and would internally use JSON.parse instead of JSON.parseList anyway. Is anyone aware of a smart way to support mapping of Lists using JsonFeature?

What happened to

kotlinx.serialization

? I have installed IDEA plugin, added and updated Maven repositories, but

<artifactId>kotlinx-maven-serialization-plugin</artifactId>
                    <version>${serialization.version}</version>

are not found

just wanted to ask.. the bug where automatically finding the serializers for types in another submodule, is there a better solution than adding

@Serializable(with=)

? that also does not work with lists afaik

Forwarding my question and thread here as this should be the better place for it.

https://stackoverflow.com/jobs/204900/drupal-developer-ibm (By IBM at Bucharest, Romania)

Is there any technical reason

kotlinx-serialization-runtime-native

isn't provided for

linux

and other targets aside from

ios

/

macos

or it's just nobody checked if it's working as-is?

something else.. could you move or push a additional artifact to

kotlinx-serialization:kotlinx-serialization

? that would be the default location gradle looks for when adding the kotlinx repo to

pluginManagement

and resolving

id("kotlinx-serialization") version Versions.serialization

i guess thats just a concern for pre 1.3, but the same thing basically for all the gradle plugins in kotlinx (not sure if there are or how many)

@sandwwraith is there any updated doc on writing custom serializer? This one uses deprecated code and doesn't compile: https://github.com/Kotlin/kotlinx.serialization/blob/master/docs/custom_serializers.md#customizing

Am I right that

@Polymorphic

doesn't work with generics well?

class ParserTest {
    open class Field

    @Serializable data class FieldB(val a: String, val b: Int) : Field()

    @Serializable data class FieldC(val a: String, val b: Int) : Field()

    @Serializable data class Data(@Polymorphic val a: List<Field>)

    @Test
    fun testPoly() {
        val obj = JSON.parse<Data>("""{"a":[{a:"a", b: 1}]}""")
        println("obj = ${obj}")
    }
}

produces

java.lang.IllegalArgumentException: JSON at 6: Expected '[, kind: kotlinx.serialization.UnionKind$POLYMORPHIC@33e5ccce'

I have

@Serializable data class MyData (val name: String, val value: Any)

and works pretty good with

MyData.serializer()

until

value

is

java.util.Date

. What is the better way to solve it? Write custom serializer like in https://github.com/Kotlin/kotlinx.serialization/blob/master/docs/custom_serializers.md ?

Finally I've got working version for JVM but native fails with

exception: kotlin.NotImplementedError: An operation is not implemented: Serializable classes with inheritance

. It there any workaround for this?

i am upgrading from 1.2 to 1.3 and IDE and gradle tell me everything is broken, did

serialClassDesc

or annotations renamed too ?

Yeah, that's the ideal scenario. I guess if the order is reversed it's the incorrect format 🙃

this guide should probably be updated (function names etc) https://github.com/Kotlin/kotlinx.serialization/blob/master/docs/custom_serializers.md

Another kinda related question. Is there a way to get the name of the current element from the KInput? I guess this may only apply to JSON though.

Can somebody give me an example of how to use `kotlinx.serialization`: 0.8.3-rc13. With the kotlin-gradle dsl?
