Compose-style DSL for multi-page PDF generation with selectable text and vector output, top-down coordinates, simple drawing primitives (text, shapes, images), and small, standards-compliant files.

Unified pressure-sensitive pen input API with detailed events (pressure, tilt, rotation), modifier integration, PenInkSurface for low-latency ink rendering, Catmull‑Rom smoothing, motion prediction, and stroke persistence.

Manages remote data state with sealed Loading/Success/Error model, reactive flows, type-safe transitions, mapping utilities (mapSuccess/mapError), atomic success updates and zero-dependency implementation.

Painter loading images from URIs for Compose UIs, wrapping Coil in a minimal, preconfigured implementation focused solely on image retrieval without animation or extra features.

Control LED displays using a builder DSL to compose video/image areas, schedule and play modes, upload programs to HD fullcolor devices with in-memory media and device-specific transformer.

Lightweight, modular utility library offering clean APIs, minimal dependencies, core helpers, coroutine extensions, and a dedicated module for date/time and duration utilities.

Gesture-triggered debug overlay to inspect logs, grouped events, HTTP traffic, and live session state; supports custom log types/renderers, real-time search/filters, custom triggers, and zero-overhead release stubs.

Interact with Slick-Pay API via HTTP client offering asynchronous calls, Spring Boot autoconfiguration, composable WebView payment UI; handles accounts, invoices, transfers, aggregations, and errors.

Rich text editing with plain and block editors, inline formatting, custom emoji, hyperlinks, tables, smart paste, JSON serialization, undo/redo, and floating toolbars for integrated UI components.

Lightweight interactive image-cropping widget with seven aspect-ratio modes, pinch-to-zoom and pan, circular profile mask, customizable handles and guides, and full-resolution output that preserves crop state.

Annotation-driven, compile-time navigation generator: declare journeys as sealed interfaces; generates typed controllers, sealed view classes, a saved back-stack host, and declarative piggybacked side-effects.

Experimental console UI builder using Jetpack Compose compiler/runtime — declarative composable primitives, state-driven rendering, live terminal redraws, built-in effects and sample interactive apps.

Generates vector PDFs with identical, selectable/searchable text, deterministic integer-layout and font subsetting, Compose-style DSL, automatic pagination, SVG/VectorDrawable vector import, tables, images and progress reporting.

Reliable ARQ protocol implementation offering byte-for-byte wire compatibility with the reference, low-latency UDP transport, message/stream modes, tunable parameters, and pluggable congestion control.

Parses command-line arguments, simplifying handling of input options for applications. Offers structured command specification, argument grouping, and type conversion to streamline command-line interface creation.

Cron parsing and generation tool handles cron expressions, excluding day-of-week parsing, supporting execution and iteration over generated time instances.

Generates XML serialization bean serializers using annotation processing. Supports serializing/deserializing XML elements, attributes, and paths with annotations for structs like lists and maps.

Enhances testing capabilities by integrating custom assertions for the klock library, facilitating more effective date and time-related test validations.

Parses METAR raw data into structured data classes, capturing detailed weather information like temperature, wind, visibility, and cloud cover. Supports automated and manual observations.

Enables saving and retrieving serialized objects and standard data types in user preferences or app internal storage, supporting various platforms for app development.

Facilitates local publishing to a Maven repository, with tasks to modularize, add logging, and enhance documentation.

Kotlin-based Redis client supports RedisJSON with built-in serialization. Enables easy connection setup, key-value operations, and advanced element handling like persistence and expiration.

Enhances datetime functionality with type-safe APIs for time periods, similar to Swift's library. Supports operations like fetching, retrieving, iterating, and adjusting time periods across various units.

Enables integration with the Twitter API, offering streamlined access to Twitter's features and functionalities for application development.

Multiplatform library for 2D and 3D vectors and matrices, optimized for performance. Supports mutable and immutable structures, compatible with WebGL and OpenGL.

Parses EDN data, offering functions to read from character sequences or strings. Supports built-in tags like #inst and #uuid, with user tags support planned.

Contains additional concurrency primitives like CyclicBarrier, Uncancellable, HotSwap, Backpressure, and CountDownLatch not included in Arrow Fx Coroutines, inspired by Cats-effect.

Enhances language with user-friendly extensions, including customizable logging capabilities and simplified integration, requiring no additional expertise to implement.

DSL facilitates CSS creation with a syntax similar to native CSS, supporting complex selectors, nesting, dimensions, colors, at-rules, media queries, mixins, and rendering options.

Facilitates efficient networking and database caching with a fault-tolerant architecture, offering seamless state management, offline data access, and non-blocking operations for a smooth app experience.
