Pixnews Anvil-KSP Code Generators

Code generators designed for use with Anvil-KSP to simplify dependency injection in Android applications.
They make it easier to create Dagger components and modules with the Anvil-KSP compiler plugin.

Primarily shared as practical examples of how to use Anvil-KSP generators.

Below is a list of all implemented helpers:

• @ContributesActivity
  For injecting dependencies into Android Activities.

• @ContributesViewModel
  For injecting dependencies into Android ViewModels.

• @ContributesCoroutineWorker
  For injecting dependencies into Android WorkManager CoroutineWorkers.

• @ContributesTest
  For injecting dependencies into JUnit4 Android instrumented tests.

• @ContributesInitializer
  For merging initialization code fragments from submodules into the main application and executing it at application startup.

• @ContributesExperiment
  For declaring feature flags in submodules and aggregating them in the main application.

Installation

Release and snapshot versions of the library are published to a self-hosted public repository, as it's currently used in a single project.

Add the following to your project's settings.gradle:

pluginManagement {
    repositories {
        maven {
            url = uri("https://maven.pixnews.ru")
            mavenContent {
                includeGroup("ru.pixnews.anvil.ksp.codegen")
            }
        }
    }
}

The following type aliases are used in the examples:

typealias DaggerSet<T> = Set<@JvmSuppressWildcards T>
typealias DaggerMap<K, V> = Map<@JvmSuppressWildcards K, @JvmSuppressWildcards V>
