    Annotation-based library for making deep link handling better

    Deep links provide a way to link to specific content on either a website or an application. These links are indexable and searchable, and can provide users direct access to much more relevant information than a typical home page or screen. In the mobile context, the links are URIs that link to specific locations in the application. At Airbnb, we use these deep links frequently to link to listings, reservations, or search queries. Android supports deep links through declaration in the...

    Simple, fast, safe, compiled language for developing software

    ...Most objects (~90-100%) are freed by V's auto-free engine: the compiler inserts necessary free calls automatically during compilation. A remaining small percentage of objects is freed via GC. The developer doesn't need to change anything in their code. "It just works", like in Python, Go, or Java, except there's no heavy GC tracing everything or expensive RC for each object.

    A pluggable sealed API result type for modeling Retrofit responses

    A pluggable sealed API result type for modeling Retrofit responses. By default, Retrofit uses exceptions to propagate any errors. This library leverages Kotlin sealed types to better model these responses with a type-safe single point of return and no exception handling needed. ApiResult has two sealed subtypes: Success and Failure. Success is typed to T with no error type and Failure is typed to E with no success type. Failure in turn is represented by four sealed subtypes of its own:...

    Firebase Kotlin SDK

    Firebase Kotlin SDK

    A Kotlin-first SDK for Firebase

    ...Its API is similar to the Firebase Android SDK Kotlin Extensions but also supports multiplatform projects, enabling you to use Firebase directly from your common source targeting iOS, Android, Desktop, or Web, enabling the use of Firebase as a backend for Compose Multiplatform, for example. Unlike the Kotlin Extensions for the Firebase Android SDK this project does not extend a Java-based SDK so we get the full power of Kotlin including coroutines and serialization. Asynchronous operations that return a single or no value are represented by suspending functions in the SDK instead of callbacks, listeners or OS specific types such as Task.

    Gradle Kotlin DSL converter

    Gradle Kotlin DSL converter

    Convert from Groovy to Kotlin DSL for Gradle, focused on Android

    ...After a lot of pain trying to migrate from Gradle's Groovy to Kotlin DSL on Android Studio, I developed this tool to solve most migration issues and reduce the amount of work you need in order to make things ready. Please see this tool as a helper, a first resource like Android Studio's Java converter to Kotlin: it won't make a perfect conversion, but it helps a lot in reducing the time you would spend on repetitive tasks. Sometimes you just want to copy and paste. Just copy whatever you want, run the script, then paste on your IDE. The script was made to convert build.gradle in build.gradle.kts, but it can also help in the migration if you paste something that is not in Kotlin DSL format and you want it converted.

    Emerge

    Browser-based interactive codebase and dependency visualization tool

    ...You can scan the source code of a project, calculate metric results and statistics, generate an interactive web app with graph structures (e.g. a dependency graph or a filesystem graph), and export the results in some file formats. Emerge currently has parsing support for the following languages: C, C++, Groovy, Java, JavaScript, TypeScript, Kotlin, ObjC, Ruby, Swift, Python, and Go. The structure, coloring, and clustering is calculated and based on the idea of combining a force-directed graph simulation and Louvain modularity. emerge is mainly written in Python 3 and is tested on macOS, Linux, and modern web browsers (i.e., the latest Safari, Chrome, Firefox, and Edge).
