Cassowary constraint-solving implementation for UI layout, low-level solver API with weighted strengths, editable variables for interactive updates, and dual error styles (exceptions or Result-based).

Generate ROFF man pages programmatically using an abstract document model, inline styles, control directives, text-formatting helpers, and safe rendering with apostrophe handling.

Save and restore serializable objects to disk with asynchronous IO, in-memory caching, FIFO read–write locks, default values, migration helpers and observable updates via flows.

Rust-style error handling with context-aware errors, a result builder, bind() short-circuiting, bail/ensure helpers, typed/untyped errors, rich contextual propagation, and converts existing Result values for seamless interop.

Composable barcode scanner offering easy integration, built-in ScannerView or headless scanner, supports multiple code formats, and programmable torch/zoom controls via ScannerController.

Lodash-like utilities for strings, arrays, collections and maps — deep cloning, safe nested-get, flattening, range/times, uniqueness, and other helpers; zero dependencies and strong static null-safe typing.

Language parsing, AST construction and syntax-tree utilities built on an ANTLR-based parser framework, offering grammar-driven parsing helpers and code-analysis tools.

Standardized wrappers for SQLDelight, Ktor and common utilities, streamlining database, network and type handling with modular Gradle modules and testable project structure.

Embeds a WebView UI component with remembered state and navigator; supports loading URLs, HTML, POST data, JavaScript evaluation, progress, errors and native–web communication.

Lightweight, efficient binding for the Capstone disassembly engine offering a type-safe, idiomatic API, builder-based engine creation, automatic resource management, and optional WASM initialization for web.

Tiny zero-dependency logging library offering a minimal, drop-in API, tiny footprint, straightforward configuration, and no‑frills runtime, enabling easy integration for lightweight logging.

Loads .env files into runtime via DSL or fluent builder, honoring system env precedence; supports quoted/multiline values, comments, escapes, duplicates, and ignore options.

Flexible, customizable system for synchronized backgrounds across multiple child components, enabling cohesive gradients, flexible positioning, shape masking, and coordinated rendering for unified visual effects.

Flexible, customizable modal component offering animated transitions, background blur/tint/scale, stacking multiple modals, gesture-driven dismissal, flexible positioning and visibility-ratio state for fine-grained control.

Opinionated toast UI component offering stacked and expanded toasts, rich types/colors, animations, flexible positions, swipe-to-dismiss, action/close buttons, custom icons, lazy high performance.

OTP generator implementing RFC 4226/6238 for HOTP and TOTP, with configurable HMAC algorithm, digit length, secret handling and adjustable time-step for time-based codes.

Implements Unicode confusable detection per UTS #39, extends String with toSkeleton and isConfusable, embeds confusables and ignorable code point data with build-time table generation.

Design system delivering UI components, modifiers, and themes — interactive media controls, shader-driven visual effects (color-split, pixelate, noise, warp), plus a browsable catalog app.

On-device federated learning: collaborative training keeping raw data local while exchanging model updates; includes core APIs, FedAvg implementation, and Transport/Coordinator architecture roadmap.

Collection of utilities and libraries: WeakRef/WeakMap, byte-array binary tools, coroutines-based GraphQL client with subscriptions and codegen, parsers, validation, BigNum, symbolic and Clifford algebra.

Lightweight modular helpers and guides for building custom declarative UI libraries from scratch, enabling shared code, pluggable modules, and reuse of a declarative runtime outside platform-specific constraints.

Unified, type-safe API for picking, saving, capturing, sharing and reading files: single/multi/directory selection, camera photo/video, save dialog, share sheets, compose-first integration and runtime capability checks.

Enterprise-grade, type-safe filesystem API with operator-based paths and rich path utilities; coroutine-backed suspend operations for read/write/copy/move/delete/list, Compose-first integration and high performance.

Flexible, customizable snackbar system featuring swipe-to-dismiss, geometric stacking visuals, configurable animations, durations and alignment, plus an easy host/state API for transient message management.

Secure, encrypted AES-256-GCM key-value storage offering type-safe entries, Flow-based observation, coroutine-friendly async API, object serialization, hardware-backed key protection and flexible builder configuration.

Enables accurate network time synchronization via async coroutine-style API, automatic server pool fallback with retries, builder-based configuration, lightweight footprint, plus offset/snapshot time access.

Structured, type-safe error hierarchy for API failures, turning HTTP, network, parsing and validation problems into typed exceptions; includes HTTP-client plugin to extract server payloads and data-validation helpers.

Annotation-based form validation with KSP-powered compile-time metadata, zero-reflection overhead, reactive Compose-ready mutable-state form tracking, field-level error reporting, and extensible custom validators.
