Btw. There is only one single module that has public API for that library. All other modules are internal to the library

Does anyone know of a Gradle plugin to count public methods? Kind-of like dexcount but for Kotlin APIs?

Hey 🙂 For my library, I want to ensure that I don't accidently introduce source compatiblity AND binary compatibility changes. I know that there is binary-compat-validator. But are there any rules on what constitutes a source compatibiltiy break? I am willing to invest some time into this, but I would love to have a definite answer which changes break API.

I have a library that is still targeting language level 1.4 and API level 1.3. In some language ecosystems, it's considered okay to upgrade your compiler version/build toolchain as a minor version. What's the consensus for Kotlin in this case? Should I release a new major version if I update to language level 1.6 and API level 1.5?

I am failing to publish my libraries. I am getting

Execution failed for task 'publishAndroidNativeArm32PublicationToSonatypeRepository'
> No staging repository with name sonatype created

This happens even with other targets as well

Hello. I am brand new in library development and my use case is to make a library that includes local .aar library. To add local .aar I created a module containing .aar and build.gradle. It seems to work fine in my library project (resolves all dependencies), but my test project cannot add this library as dependency now. I receive

Failed to resolve: LibraryName:ModuleName:unspecified

during the sync. Any help is appreciated. Thanks!

The KotUniL library for ideomatic use of SI units is now multiplatform. Its JS version is accessible via NPM.

Hi everyone! I'm looking for an advice. I have a Java library, that I want to "convert" to Kotlin. By that I mean more idiomatic API. Particularly, this library makes use of ThreadLocal data. I want to expose them as CoroutineContext elements Could anyone recommend any articles/guidelines/best practices? An example of such a "converted" library would also be handy :)

Hello! As mentioned in the Kotlin/binary-compatibility-validator#42, the BCV team is not yet ready to accept a contribution for JS/TS support, or even to do due diligence and see if this is a reasonable addition for the future. I’ve created a Gradle plugin that adds support for JS APIs to the KotlinX Binary Compatibility Validator. Originally made for the Fluxo state management framework, now released for general use. • Uses generated TypeScript definitions to do so. • Can be used with any Gradle module with Kotlin/JS target. Either multiplatform or Kotlin/JS. • Will be supported until the official Kotlin/JS support is added to BCV itself. Compatibility tested with: • BCV: 0.8 — 0.13.1 • Kotlin: 1.6.20 — 1.9.0-Beta • Gradle: 7.4+ See how to use it with the JitPack here: https://github.com/fluxo-kt/fluxo-bcv-js#readme Publication on Gradle Plugin Portal is in progress. Please try to use the plugin. I’d appreciate any feedback.

Hello. I am trying to make a release through gitlab, but as I understand they do not publish. Gitlab is very flexible, so they allow to make project and its releases public, but give access to source code only for members of organisation. I tried publishing with Jitpack, but it seems that it must have access to source code and it does not publish from gitlab releases. Are there any other publishing tools that would publish from release files instead of source code? My goal is to publish library that does not need credential access, but hides all the source code. https://docs.gitlab.com/ee/user/project/releases/

Hey, how could I deprecate a single function parameter? Example

fun createSimulation(
    @Deprecated("use env.enableConsoleLogger() instead")
    enableConsoleLogger: Boolean = false,
    durationUnit: DurationUnit = MINUTES
){ print() }

It seems that the @Deprecated is not applicable for parameters.

Assuming I have an interface like this that is part of my public API:

interface SomeInterface {
  fun function1(param1: Param1)
  fun function2(param2: Param2)
}

Can I somewhat evolve it without having to introduce a new interface name?

// Can I evolve it into somthing like this?
interface SomeInterface {
  fun function3(param3: Param3)
  fun function4(param4: Param4)
}

Maybe using default methods? Or do I need to deprecate and find a new name?

hi there. i am developing my very first KMP library using multiplatform(“1.9.0”) its target all the platform (i think , i added all) . but for ios version i cant use this library if its multiplatform version 1.8.21 . other platform seems fine , getting errors like

Incompatible abi version. The current default is '1.7.0', found '1.8.0'. The library produced by 1.9.0 compiler

anyway for android i need to change the plugin version bellow 8.0 otherwise get

The applied Android Gradle Plugin version (8.1.0) is higher than the maximum known to the Kotlin Gradle Plugin

it worked if i change the version as it clear in the log .but i need to use older version and they dont support android 34 (show just a warning though) . i see most of the famous library support so many multiplatform version . how to do that ? find a middle multiplatform version that supported by latest and old ? which version will be most suitable ? and also in 1.9.0 the androidTarget() cant be used directly i needed to use android.library plugin thats ok but its not support newer library version ? i needed to use pluginResolutionStrategy and use module for android build tool . and some build tool version have problem too . thanks for your time .any insight will be a big help.

Im in the proccess of making my jetpack compose library work with on compose multiplatform, i was wondering what is the best way to print log statments in debug mode? in Android i was just using

Log.d

and i currently just print them with

println

but i guess its not the best option, i there a better way to do it? do i have to use a library for that?

Is it possible to publish a kmp library that targets (desktop, ios, android) with github actions using the github provided macos runner?

I'm trying to decide which kotlin-stdlib version I should be using in my libraries. Pretty much all the libraries I use (http4k, moshi, okhttp, forkhandles, with the unsurprising exception of jackson-module-kotlin), use the latest kotlin-stdlib version at the time of their release. I've been doing the same, but I just recently had a user complain they couldn't use my library because they were still on Kotlin 1.6. The only time I've ever had a blocker to upgrading is when Kotlin 1.5 broke my usage of Javalin's OpenApi annotations. I'm not sure if I should be trying to target some minimum stdlib version, or if it's on the user to stay up to date. What does everyone else do? 🤷

Any thoughts on using context receivers in libraries implementations (not public API)? Is it safe to do or is there the possibility it will break in future releases?

Hi! I get a "closed fail" on Sonatype without any obvious reason… Have you every experienced this?

HI Devs, I am trying to create my own library for my project, Please help me how to create KMP library for iOS and Android. Please suggest me reference links

Idea: generalized version of

Pair

and

Triple

called

Tuple

that uses code gen to create variables

first

,

second

, etc. (or

ItemN

like in C#), based on the number of arguments passed in. Is this possible? Where would I begin? I have never made a compiler plugin.

Hi Team, While running commonTest Unit testing code for native iOS I am getting below error Execution failed for task 'sharediosSimulatorArm64Test'. > There were failing tests. See the report at: file:///Desktop/library/shared/build/reports/tests/iosSimulatorArm64Test/index.html Can I run the commonTest cases for iOS or it should be test with XCTestcases in iOS I am able to run the Android without any errors Snippet:

enum class  LoginResponse {
    LOGIN_SUCCESS,
    LOGIN_INCORRECT_USERNAME,
    LOGIN_INCORRECT_PASSWORD,
    LOGIN_USER_CANCELLED,
    LOGIN_AUTH_FAILURE,
    LOGIN_AUTHORISATION_FAILURE,
    LOGIN_LICENCE_NOT_VALID
}


object ProductManager {

    var loginResponseType =  LoginResponse.LOGIN_SUCCESS
 @Test
    fun  testIncorrectPassword() {
        ProductManager.loginResponseType = LoginResponse.LOGIN_INCORRECT_PASSWORD
        ProductManager.login(baseView = Any(), onSuccess = {
        }, onFailure = {
            assertEquals(it, "Failure")
        })

    }
}

if I remove below line

ProductManager.loginResponseType = LoginResponse.LOGIN_INCORRECT_PASSWORD

its running without error

I have created a kmp library for ios / android. On IOS part it uses some swift-only library using cinterop. When i run: assembleXCFramework everything works. But when i try: publishToMavenLocal it complains that my swift library object in not found: unresolved reference: MySwiftObj What am i doing wrong?

Can I have the following: 1. Create a KMP Library MyAwesomeSDK, which provides an interface to encode / decode / verify JWT (Needed for operation of my AwesomeSDK) 2. Create an iOS XCFramework library MyAwesomeIOSDeps, that implements this interface with the help of SwiftJWT. 3. Send my consumers the maven published KMP Library MyAwesomeSDK and MyAwesomeIOSDeps.xcframework 4. My Consumer will create an iOS Project / KMP App, add dependency on MyAwesomeSDK and MyAwesomeIOSDeps 5. My Consumer will init MyAwesomeSDK from swift or kotlin with:

import MyAwesomeSDK

import MyAwesomeIOSDeps

MyAwesomeSDK.Init(MyAwesomeIOSDeps.JWTImpl())

Slack Conversation

Currently working on a KMP/UI library. Any thoughts? https://github.com/lightningkite/rock One thing I'm questioning in the current implementation is the use of

value class

es to wrap HTML elements, as it is increasing the binary size. However, using

actual

typealiases yields problems because there are multiple semantic elements in the library that correspond to the same variant of

HTMLElement

, resulting in function clashes in the `actual`s. If anyone has a solution to that I'd love to know!

I'm kindly asking for some feedback. I've implemented forms support with validation in my experimental wasm/js framework. In this example code I've implemented a simple form based on Bootstrap custom validation. https://github.com/rjaros/kilua/blob/main/examples/bootstrap-form/src/commonMain/kotlin/main.kt What do you think about the code? Is it readable? Can you understand what this code does without deeper knowledge of the framework itself? Any other thoughts? Thanks for your time!

When I publish my library it seems to include, some scripts which I do not want. They don't depend on anything in the library but are used to generate some scaffolding. What would be the best way to exclude these? It is KMP lib and these generators are situated in jvmMain while my lib is entirely located in commonMain

What's everyone's take on

explicitApi()

? I get the intent but feels like it duplicates tools like kotlin binary compatibilty validator or metalava. With kbcv, forgetting to add an

internal

fails the build just like

explicitApi()

would. Same for implicit return types (

fun foo() = ...

) And kbcv saves the ceremony of adding

public

everywhere (in addition to actually tracking the API). In its current state, the only win of

explicitApi()

seems to be that it removes the "unused symbol" warning for potentially unused public API but even that feels borderline counterproductive given that tests should cover most of public API and worst case, it's possible to remove with

@Suppress("unused")

. Thoughts?

Dear developers who are using

jackson-module-kotlin

in libraries. As the maintainer, I have received several binary compatibility issues caused by code that initializes

KotlinModule

from its constructor. On the other hand,

KotlinModule

constructors have been deprecated for over 2 years now. The recommended initialization method for

KotlinModule

is either of the following (available since 2.12) • Using the builder • Using the `kotlinModule` function • (or Use other extensions) I would appreciate it if you all could modify the code. Thank you.

HI Developers, Can I use MSAL authentication and authorisation in KMM?
