ReactiveX/RxKotlin

The repository was initialized with essential project files including the Apache 2.0 license, contributing guidelines, release process documentation, and a comprehensive README detailing extension functions for RxJava 1.x, 2.x, and 3.x. Additionally, build infrastructure was added, including a \.gitignore\ file, a Travis CI configuration for automated builds and releases to Bintray, and Gradle wrapper scripts for cross-platform compatibility.

(repo-wide) · high confidence

Added two new example applications in the \src/examples\ directory: a general Kotlin examples file (\examples.kt\) demonstrating RxJava3 usage with \Observable\, \CompositeDisposable\, and various operators, and a Retrofit integration example (\retrofit.kt\) showing how to use RxJava3 with Retrofit and Moshi for network requests.

A new shell script, buildViaTravis.sh, has been added to the gradle directory to automate the build and release process on Travis CI. This script configures the build environment to handle pull requests, branch builds, and release tags differently, ensuring that the project is built correctly in each scenario and that release artifacts are published to Bintray and Sonatype.

gradle · medium confidence

The \Flowables\, \Maybes\, \Observables\, \Singles\, and \Single\ objects in \src/main/kotlin/io/reactivex/rxjava3/kotlin/\ mark several \combineLatest\ and \zip\ overloads as deprecated. These methods are obsolete due to the new type inference algorithm in Kotlin 1.4, and will be removed in a future release. Users should migrate to the corresponding \Flowable\, \Observable\, \Maybe\, or \Single\ static methods directly.

src/main · high confidence

The project's Gradle wrapper has been upgraded to version 5.4.1, ensuring that builds use a consistent and modern version of the Gradle build tool. This change updates the distribution URL and local storage paths in the wrapper configuration, which may affect how the build environment is initialized.

gradle/wrapper · medium confidence

Added new test files in the \src/test/kotlin/io/reactivex/rxjava3/kotlin\ directory to verify the behavior of the RxJava3 Kotlin language adaptor. The new tests cover core reactive types including \Observable\, \Flowable\, \Single\, \Maybe\, and \Completable\, as well as utility classes like \Observables\ and \Singles\. These tests validate the functionality of Kotlin-specific extension functions and operators such as \subscribeBy\, \toObservable\, \toFlowable\, \zip\, and \combineLatest\, ensuring that the Kotlin API behaves as expected.

src/test · high confidence

The build system has been migrated from Groovy to Kotlin DSL (build.gradle.kts), and dependencies have been updated to target RxJava 3.0.6, Kotlin 1.4.10, and various test and example libraries. This change modernizes the build configuration and aligns the project with the latest RxJava 3.x API.

ReactiveX/RxKotlin was measured the same way every project in this corpus was: the same rubric, at a pinned commit, with the result published in full. Point a surveyor at a repository you know and see whether you agree with it.
