kotlinlang #kodein

I have created a brand new Android application and am trying to add Kodein, but the moment I add it an Activity, I get a weird (and unhelpful) exception when building. My activity:

class MainActivity() : AppCompatActivity(), DIAware {
    override val di by di()
    
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

    }
}

My application:

class PromptsApplication: Application(), DIAware  {
    override val di by DI.lazy { }
}

The exception:

Seeking perspective: Hi! I'm coming from a world of manually-hacked-up DI in Ruby, Go and Java, and I'm a noob for both Kodein and Kotlin. I am building a tool/service (commandline, eventually maybe Android) and previously I would build a

AppConfig

instance — containing references to objects that implement interfaces like

DB: IDatabase

, etc — and pass that

appConfig

into the constructors that implemented [various interfaces] for my service. All very typical factory-pattern stuff - the (for example)

appConfig.DB.query()

methods would then be used by service methods (via a "retrieval"-type approach) and the appConfig reference itself would be blindly passed on to any child-factories which need to be created. But I am learning Kodein and I am messing around with this blog post which suggests making the companion object for

Foo : IFoo

into a

FooFactory

by declaring a

companion object { fun create() : IFoo = ... }

method. With that context, QUESTION: What's the proper Kotlin & Kodein approach to solving the problem of passing an instantiated

appConfig

reference into a

FooFactory

that is the companion object of

Foo

? In fact, would this be stupid to do? I am trying to avoid endless invocations of

Foo(appConfig: DI)

by passing

appConfig

into the

FooFactory

when I create the

FooFactory

, I could maybe declare

Foo.appConfig

as a

lateinit

var in the

Foo

factory/companion-object, and then set it via a static method call, but I feel sure that there must be a better, more typical way in Kodein - possibly modules?

When i try to build my lib with ci error says that core isn't compatible with latest kotlin's version

Quick Question: if I am implementing an extension method for a Java class, what's the best practice for pushing DI/Kodein into the extension method? There's some behaviour configuration which I want to be able to vary in tests, but I don't have a clear factory pattern to work with because extension methods are resolved statically.

Hi guys, does Kodein 7.2.0-master-95 have the IR compiler enabled? I see from the kodein gradle plugin that from 5.0 both legacy and IR are enabled, is this correct?

Is it possible to load/add DI.Module dynamically to the graph(container?)? Let’s say I already have DI instance and I would like to load/add some additional dependencies to it. Before I was using Koin and there is a function on Koin instance to

loadModule/unloadModule

, what’s the Kodein way for it? 🙂

zalewski.se

11/05/2020, 11:53 AM

Another thing is, how do you set DI for tests? With Koin before every test we start the whole DI where it prepare all modules and after the test we close it. How about Kodein? Is there any way to clean the graph between tests?

Hello Kodein. I hope all is well and that you and your family are safe & healthy during this time. I'm learning Kodein now, and writing a test project with it, for an excellent job interview. Since the last day, I had an error, not solved yet. This is the error: org.kodein.di.Kodein$NotFoundException: No binding found for bind<ForecastRepositoryImpl>() with ?<ForecastFragment>().? { ? } Could you please help me with this? Taking this job is vital to me. Thanks a lot.

Is it possible to stop kodein to print out the whole tree of type options out there? This list is becoming ridiculously long, as I have multiple houndreds dependencies.

Hi everyone. Are there Stack Overflow aficionados here? I'd like this edit to be approved, since the meaning of "Kodein" has changed a lot since @apatrida's initial creation of the tag. If you could review and approve the edit (only of course if you actually do), that would be really helpful! https://stackoverflow.com/review/suggested-edits/27546214

Hey guys. I am wondering if you or anyone you know is using Kodein-DI-Framework-TornadoFX. TornadoFX code base has not seen any code commit since April 16, the last published version dates to January 31 and it still uses Kotlin 1.3.61. Furthermore, I suppose Jetbrains Compose will probably gain more traction in the desktop space. I am therefore wondering if it makes sense for us to maintain Kodein-DI-Framework-TornadoFX. Any feedback regarding TornadoFX would be appreciated 😄

I'm trying to inject instances of an interface using the class name a la Class.forName(...).newInstance()... I understand that you can do something like...

val kodeinContainer = DI {

bind<MyInterface>(tag = "com.dude.MyInterfaceImpl1") with provider {MyInterfaceImpl1()}

bind<MyInterface>(tag = "com.dude.MyInterfaceImpl2") with provider {MyInterfaceImpl2()}

but can you do this dynamically? For example, like....

object MyInjector {

val kodeinContainer = DI {}

fun main() {

MyInnjector.kodeinContainer.bind<...>(...) ...

Hi, could someone please share a complete example how to use scopes? What I’m trying to do: I have a singleton which needs to be recreated when the server environment is changed from Test to Prod via the debug menu. I figured I should use scopes for that, but the documentation doesn’t have a complete working example that is easy to follow.

Hey guys, we've just released Kodein-DB 0.5.0! The changelog: https://github.com/Kodein-Framework/Kodein-DB/releases/tag/0.5.0-beta The documentation: https://docs.kodein.org/kodein-db/0.5/ As is usual for beta versions, this release brings some breaking changes (all documented in the changelog of course). The most important is the fact that

indexSet

no longer exists as

Set<Index>

has been replaced by

Map<String, Any>

. Simply replace

indexSet

with

mapOf

and you should be good to go! Please let me know if there's anything we can do to help 🙂. We are very interested in feedback for Kodein-DB beta!

Kotlin 1.4.30 is OUT 😄 Will there be an option soon to compile for IR with Javascript? 🙂

Hi folks! Kodein-DI 7.3.0 is out! This mostly brings kotlin 1.4.30, with JS IR backend 🙂 (still on Jcenter, this could be the last release with Bintray...)

Indeed, I forgot something in the project configuration... 7.3.1 should work https://dl.bintray.com/kodein-framework/Kodein-DI/org/kodein/di/kodein-di-js/7.3.1/
