to get the request object but this one doesn't contain the headers we're adding through interceptors for example... Is there any extension to get the real request? Or am I correct to assume I can't use interceptors if I want to achieve this?

An interceptor is the mechanism, ideally the last network interceptor

Thanks, I'll check this again, but my issue is that interceptors receive the response before the parsing of the body response into its generic type (by retrofit or Apollo). Ideally I'd like to know the request succeeded and the response was correctly parsed into its generic type then log the request + response following some business logic we have

07/24/2022, 5:01 PM

Sounds like what you want is asymmetric then. For the request you want the last network interceptor. For the response the only real hook is a logging adapter or logging converter, although the converter doesn't see headers.

Hi all - is there a guide on how to setup SqlDelight on JVM? the guide here is only for a

<http://JdbcSqliteDriver.IN|JdbcSqliteDriver.IN>_MEMORY

, but I'm looking for something more permanent

it's a standard jdbc string so you want

jdbc:sqlite:/path/to/file.db

for a persisted sqlite database

Hey 👋 Does anyone have an example of how you could test a fragment/activity using paparazzi? Or is it only for tests on individual views?

It's only for rendering views

How can I parse with Moshi double nested dynamic objects? I can have different types of

trigger

in my JSON. Then, for

trigger

type

SENSOR

I can have (nested) different types of

condition

(examples see in thread 🧵:

In general the strategy is to use a custom adapter which calls

readJsonValue()

that will give you a

Map

(for a JSON object) which you can query to determine the "shape" of the object. Then, you can delegate to the correct adapter which can parse that specific shape. So for your root object you would delegate to an adapter for a

Time

Sensor

object. Now the problem is fractal so you just repeat yourself. You register a custom adapter for

Sensor

which does the same thing (reads the json a "value" and inspects it) to create either an

AlwaysCondition

or a

ThresholdCondition

Now, Moshi has a built-in type which will probably do both of these levels of shape-detetion for you: https://github.com/square/moshi/blob/master/moshi-adapters/src/main/java/com/squareup/moshi/adapters/PolymorphicJsonAdapterFactory.kt

07/28/2022, 3:56 PM

Your case seems simple where there's always a JSON key that acts as a discriminator whose value determines the shape and thus the type to deserialize. Its documentation should get you pretty far. You'll register it twice, once for

Trigger

and then once for

Condition

Thank you! I registered a custom Adapter for both

Trigger

and

Condition

types with

@ToJson

and

@FromJson

function implementations. I then registered them both with Moshi using

add()

, but then the internal

Condition

object was serialized as plain string (with all the JSON symbols like

{}

etc. escaped with

I suppose PolymorphicJsonAdapterFactory will help with that?

07/28/2022, 4:02 PM

If you are delegating in a custom adapter you generally want to be using

JsonWriter

as a parameter which gives you access to write raw JSON (or to pass the

JsonWriter

along to a delegate adapter so it can). Perhaps you could look at the implementation of the polymorphic adapter to get some ideas. There's also some examples in the repository for custom adapter things.

Thank you very much for such quick and comprehensive answers! 🙏

Update: actually I now discovered the bug in my

@ToJson

implementation: I was using

toJson()

instead of

toJsonValue()

. That's why the serialized JSON was escaped like a plain string. It didn't have anything to do with nesting. But I will switch to a polymorphic adapter factory anyway, because then I won't have to implement from/to JSON functions myself and won't be able to make these kind of errors.

Hi, is it possible to change Paparazzi's snapshots output directory? Readme says it "defaults to `src/test/snapshots`", but I can't find a way to change it. https://github.com/cashapp/paparazzi

I'm using Retrofit's

MoshiConverterFactory

for my API calls, however it doesn't support sealed classes containing `object`s. I'm trying to generate adapters for the sealed class hierarchy using

moshi-sealed

, but I still get the error

object Always cannot be serialized

. Here the hierarchy:

@Keep
@JsonClass(generateAdapter = true, generator = "sealed:type")
sealed class TriggerCondition(val type: String) : Serializable {

    @Keep
    @TypeLabel("ALWAYS")
    object Always : TriggerCondition("ALWAYS")

    @Keep
    @TypeLabel("NIGHT")
    object Night : TriggerCondition("NIGHT")

    @Keep
    @TypeLabel("LIGHT_SENSOR")
    @JsonClass(generateAdapter = true)
    data class LightSensor(
        val sensorInfo: SensorInfo,
    ) : TriggerCondition("LIGHT_SENSOR")
}

Hello, why is my interceptor not proceeding request?

class TokenInterceptor @Inject constructor(
    private val preferencesRepository: PreferencesRepository,
    private val cognitoRepository: CognitoRepository
) : Interceptor {
    override fun intercept(chain: Interceptor.Chain): Response {
        return runBlocking {
            val request = chain.request().newBuilder().build()

            if (preferencesRepository.isTokenExpired()) {
                cognitoRepository.login(
                    number = null,
                    password = null,
                    refreshToken = preferencesRepository.getRefreshToken(),
                    loginType = CognitoRepository.LoginType.RefreshToken
                ).collect()
            }

            chain.proceed(request)
        }
    }
}

Looking at the KotlinPoet documentation https://square.github.io/kotlinpoet/ I can’t seem to find how one would generate a function with a generic argument with an upper bound to some type, something like:

fun <T : SomeType> foo(param: Bar<T>): Unit {
  asdf(myParam)
}

Is there some part of the docs which I am missing? If so I’d really appreciate any pointers.

When, approximately can we expect Melecule supporting native targets? JetBrains Compose 1.2 needs to be stable?

08/05/2022, 5:43 PM

Yes

08/05/2022, 5:44 PM

And it will only support the native targets they support which a few weeks ago seemed like only iOS, unfortunately

Are you planning to release an alpha version of the molecule to get some early feedback? 🙂
