A modern programming language that makes developers happier.

kotlinlang

Is there any utility for turning a hierarchy Kotlin data classes into code.  Want to fetch some data from an API, and turn it into executable code for test fixtures.

not a joke - ChatGPT is actually excellent at this

Give it the data classes, ask for better toString values.

I'm not sure exactly what you mean but it sounds like you want to serialise your classes; in which case I recommend `kotlinx.serialization` library.

No, I meant code I can copy and paste into my IDE to recreate a data class that would be exactly equal.

I don't need perfect, or handling all possible types. Just knowing to quote strings correctly

Data classes are already code, though. Do you mean you want to turn JSON into code that creates data class instances with the same data?

I have an instance of an arbitrary data class at runtime. I want to turn it into a string I can put into my code to reinflate later

Ah I see. I think someone has asked this question some time ago, but I don't remember the outcome

<@U6Q90DDHR> are you _sure_ you don't want `kotlinx.serialization`

Turning instances of data classes into strings that can be reinflated later on is kind of it's thing

Maybe, but I don't want to have to use kotlinx serialisation on the other side. Just copy and paste.

I have other solutions. More curious if an inspect like operation is supported.

I'd like the final form to be affected by refactoring, for example

I think we need an example. I can't be alone in feeling I haven't fully grasped what you're looking for.

```val conferenceList = GetConferencesQuery.ConferenceList(conferences = listOf(
        GetConferencesQuery.Conference(
            "kotlinconf2023",
            listOf(
                LocalDate.parse("2023-04-12"),
                LocalDate.parse("2023-04-13"),
                LocalDate.parse("2023-04-14")
            ),
            "KotlinConf 2023"
        )
...

val textFixtureInspector = TestFixtureInspector()

println(textFixtureInspector.inspect(conferenceList))```

```GetConferencesQuery.ConferenceList(conferences = listOf(
        GetConferencesQuery.Conference(
            id = "kotlinconf2023",
            dates = listOf(
                LocalDate.parse("2023-04-12"),
                LocalDate.parse("2023-04-13"),
                LocalDate.parse("2023-04-14")
            ),
            name = "KotlinConf 2023"
        )```
