Extendable MVI framework for Kotlin Multiplatform with powerful debugging tools (logging and time travel), inspired by Badoo MVICore library

TimeTravel can't serialize Enum implementing JvmSerializable

My Enum:

    enum class ConnectionStatus(val friendlyName: String): JvmSerializable {
        DISCONNECTED("Disconnected"),
        CONNECTING("Connecting"),
        CONNECTED("Connected"),
        AUTHENTICATED("Authenticated"),
    }

Stacktrace:

Please consider adding support for the iosSimulatorArm64 target.

This currently fails due to the issue described in https://github.com/badoo/MVIKotlin/issues/200

hi, i encount some serous problem that i struggle for several days.

I use MVIkotlin, its version is 2.0.4

there is a SuspendExecutor, following is my own source.

my problem is i cant execute both collect meantime, everytime only the first collect is executed. i need to check what method the user choose to use my app, login as account or just visit, so i need to check these in executeAction

im not sure whether you can understand what i say, thanks

Is the any correct way to get know about finishing coroutine executor.

For example, we have a some form and Save button. When user clicks Save button, we send intent to save this form on server side. Executor handles the intent and makes API call to server. After success response user is navigated to another page, on error user see error message.

It seems the directories sample/todo-app-{android,ios} were effectively split up between the coroutines and reaktive versions but a few files are left in the old locations.

Most notably, I updated my git checkout and tried to load sample/todo-app-ios/todo-app-ios.xcodeproj unsuccessfully because its dependencies are now missing.

Not related to the library itself, but would be nice to have it as an issue.

Hello @arkivanov , I've noticed that search in the repo doesn't work anymore. Even tried with suggested approach, still no success: https://docs.github.com/en/search-github/searching-on-github/searching-in-forks

I tried this request also: https://github.com/search?q=isAssertOnMainThreadEnabled+repo%3Aarkivanov%2FMVIKotlin+fork%3Atrue

Who knows how to search on the forked repository?

Currently Store.init throws an error if the store is already initialized. This makes the initialization inconvenient if the store is retained via InstanceKeeper.

Hello @arkivanov ,

First of all I want to congratulate and thank you for all the hard work you put on this library. I've been using it the past few months with a multiplatform app that runs on JS, Android and iOS and I am really happy with the results so thanks so much for your contribution to the community!

I was hoping to add tvos support to the application I was wandering what is the current support for the tvos target. I've seen that no artifacts are published to maven repository but checking the code of the repository and the code of the com.arkivanov.gradle.setup plugin that the tvos target is not configured by default but there are some bits of code indicating that may be configured (I've not checked the code deeply but I have seen the posibility of adding the targets through the tvosCompat() function of the plugin). Could I fork the project and try to setup the support the tvos locally and expect it to work or is disabled by default due to some other reason?

Thank you again for your time and work!

The links to sample projects in the ReadMe are dead.

Consider updating the doc to link the new sample projects, including maybe the one in compose-jb repository aswell.

• Time Travel Client App is now packaged on CI for Linux and Windows, macOS can be packaged locally from sources
• Time Travel IDEA plugin is able to connect to Darwin and JVM apps

We run unit tests in KMM on our stores which are using coroutines and when the test runs we see exceptions like this in the log:

java.lang.NullPointerException
	at com.arkivanov.mvikotlin.utils.internal.MainThreadAssert.getMainThreadId(MainThreadAssert.kt:9)
	at com.arkivanov.mvikotlin.utils.internal.MainThreadAssertKt.isMainThread(MainThreadAssert.kt:24)
	at com.arkivanov.mvikotlin.rx.internal.BaseSubject$1.invoke(BaseSubject.kt:13)
	at com.arkivanov.mvikotlin.rx.internal.BaseSubject$1.invoke(BaseSubject.kt:13)
	at com.arkivanov.mvikotlin.rx.internal.BaseSubject.subscribe(BaseSubject.kt:23)
	at com.arkivanov.mvikotlin.main.store.DefaultStore.labels(DefaultStore.kt:74)
	at com.arkivanov.mvikotlin.logging.store.LoggingStore.labels(LoggingStore.kt)

This does not actually cause the tests to fail, but is annoying seeing this noise in the logs. It fails because we are not actually running on an Android device so there is no main looper. You have the isAssertOnMainThreadEnabled variable to disable maint thread assertions but it doesn't disable this check in BaseSubject.

It would be good to have a list of companies/users/projects where MVIKotlin is used. I suggest to stick to the following format, but feel free to omit/add/modify any details. ❤️

Project name: <project name> Project type: production/pet/sample Company name: personal/<company name> Supported platforms: Android, JVM, Web, iOS, macOS, etc. Link (an open source repository or a web site): <link>

The plugin functionality is actually similar to the desktop client app, it can connect to Android, JVM and Darwin apps. Also there are typos, e.g. "All recording events will appear ...". Link: https://arkivanov.github.io/MVIKotlin/time_travel.html
