    Buck

    Buck

    Build system that encourages the creation of small, reusable modules

    Buck is a build system developed and used by Facebook. It encourages the creation of small, reusable modules consisting of code and resources, and supports a variety of languages on many platforms. Buck builds independent artifacts in parallel to take advantage of multiple cores on your machine. Further, it reduces incremental build times by keeping track of unchanged modules so that the minimal set of modules is rebuilt. Buck only uses the declared inputs, which means everybody gets the same results. Buck looks at the contents of your inputs, not their timestamps to figure out what needs to be built. As a result, incremental builds should always be correct, so there's no need to perform a clean build. With buck query, you can better understand your dependencies and what is required to build your product. With buck project, your project can be better understood by your IDE, making you and your team more productive.

    ChatGPT Java API

    ChatGPT Java API

    Java SDK for seamless integration with ChatGPT APIs

    ChatGPT-Java is a Java SDK created by PlexPt that offers a convenient, out-of-the-box integration with the OpenAI ChatGPT API (including models like GPT-4o, GPT-5) for Java applications. The library supports chat completions, token counting, function calls, streaming responses, proxy configuration, custom API host, and integration with frameworks such as Spring (via SseEmitter). It abstracts the HTTP interaction and JSON parsing into simple Java objects and builders while handling details like token usage and model selection. It is published to Maven Central under the group com.github.plexpt, e.g., version 5.0.1. The SDK is designed for developers building chatbots, conversational assistants, and integrations in Java or Spring ecosystems. Being open source under MIT, it provides transparency and community contributions.

    Epoxy

    Epoxy

    Android library for building complex screens in a RecyclerView

    Epoxy is an Android library for building complex screens in a RecyclerView. Models are automatically generated from custom views or databinding layouts via annotation processing. These models are then used in an EpoxyController to declare what items to show in the RecyclerView. This abstracts the boilerplate of view holders, diffing items and binding payload changes, item types, item ids, span counts, and more, in order to simplify building screens with multiple view types. Additionally, Epoxy adds support for saving view state and automatic diffing of item changes. We developed Epoxy at Airbnb to simplify the process of working with RecyclerViews, and to add the missing functionality we needed. We now use Epoxy for most of the main screens in our app and it has improved our developer experience greatly. If you are using layout resources in Epoxy annotations then for library projects add Butterknife's gradle plugin to your buildscript.

    Litho

    Litho

    A declarative framework for building efficient UIs on Android

    Litho uses a declarative API to define UI components. You simply describe the layout for your UI based on a set of immutable inputs and the framework takes care of the rest. With code generation, Litho can perform optimisations for your UI under the hood, while keeping your code simple and easy to maintain. Litho can measure and layout your UI ahead of time without blocking the UI thread. By decoupling its layout system from the traditional Android View system, Litho can drop the UI thread constraint imposed by Android. Litho uses Yoga for layout and automatically reduces the number of ViewGroups that your UI contains. This, in addition to Litho's text optimizations, allows for much smaller view hierarchies and improves both memory and scroll performance.
