Implements ULIDs with cryptographic security, providing lexicographically sortable, URL-safe, 128-bit compatible identifiers. Supports timestamp-based generation and multiplatform environments with minimal dependencies.

Library enables exact base-10 arithmetic using native decimal types across platforms, providing consistent semantics and a single API for handling decimals, percentages, and currency amounts.

Enhances integration with the PC/SC API for smart card readers, offering an object-oriented interface, helper methods, and platform abstraction for streamlined card interaction across platforms.

Implements SHA-256 hashing with a minimal API to compute 32-byte digests from byte arrays; compact, lightweight, reference-derived, suitable for embedding.

Modernizes and streamlines a mobile object-database client: updates language and build toolchain, simplifies native builds using prebuilt binaries, cleans repository, preserves API for zero-effort migration.

mDNS announcer supporting broadcast-only service registration with A/PTR/SRV/TXT records, configurable hostname/IP/port/TXT, event hooks, AirPlay2 example, periodic broadcast and C/C++ shared-lib bindings.

Firebase Admin SDK for service-account credentials, OAuth2 token caching, JWT auth, and FCM messaging with rich notifications, topics/conditions, plus custom HTTP and crypto support.

Parses CSI/SGR ANSI escape sequences into styled text slices with color, intensity and style metadata; reconstructs plain text, iterates lines, and supports all 16 ANSI colors.

Unified API for retrieving system app directories (temp, documents, cache, downloads), synchronous calls, application-id isolation for per-app subdirectories and standard path mappings.

Functional monads for safer null and error handling: Maybe, Either, Try; error-accumulating types, evaluation combinators for combining results, and tuple utilities up to quintuple.

Lightweight signal abstraction for emitting typed events and connecting synchronous handlers. Includes connection handles and a global named-signal registry for simple, minimal event routing.

Type-safe test fixture generation with a composable, declarative API for building complex object graphs, nested overrides, sealed/enum/null handling, annotation-driven auto-registration, and testing-framework integration.

CommonMark-compliant Markdown parser and renderer offering AST access for inspection and manipulation, extensible with GFM-style extensions (tables, strikethrough, autolink), outputs HTML, Markdown, or plain text.

MVP JDBC wrapper around SQLCipher offering a JNI-backed custom JDBC driver, unified API, native bridge, build tooling, and CI-friendly encrypted DB samples.

Unified toolkit offering app lifecycle, device and app info, clipboard read/write/observe, network and keyboard monitoring, haptics, sensor observation, navigation, share-sheet and file pick/save helpers.

Pure systems-programming toolkit enabling bit-exact C semantics with single-heap memory, C-compatible types, deterministic floating-point, and dual-mode bitshift engine for reliable C-to-language porting.

Async client for the KLIPY API enabling GIFs, stickers and clips search, trending, share logging, ad-aware responses (HTML/iFrame), customizable HTTP client and user-agent.

Type-safe, reflection-free diffing of serializable data structures, performing deep comparisons of nested objects, lists, and maps; supports compile-time serializers, customizable list strategies and formatted statements.

Event-driven, non-blocking asynchronous runtime featuring multithreaded work-stealing scheduler, reactor, async TCP/UDP and runtime primitives; faithful line-by-line transliteration of upstream implementation with provenance headers.

High-performance arbitrary-precision BigInteger and BigDecimal implementations with zero-overhead standard aliases, pure native hot paths plus LibTomMath fallback, and extensive microbenchmarks demonstrating major speedups.

Direct Compose Desktop rendering into toolkit-owned Wayland wl_surface via EGL, bypassing X11/JAWT; creates wl_egl_window, resizes buffers, supports integer buffer and fractional UI scaling.

Enables easy execution of native functions in fission.io, offering a simple setup with dependency inclusion, function registration, and specialized environment deployment for seamless function routing.
