Gesture-based image zoom library designed for enhanced viewing capabilities. Features include dynamic scaling, rotation, subsampling for large images, and integration with popular image loaders.

Library facilitates mathematical operations and utilities, including angle representation in degrees or radians with conversion, normalization, and arithmetic capabilities, along with trigonometric functions.

Enhances app interfaces with dynamic color support, light and dark themes, and Material 3 design principles. Offers easy customization for consistent aesthetics on Android 12+ and Windows.

Simplifies and unifies JNI development by providing a common interface and tools for generating JNI-compatible function stubs. Enhances Java-Kotlin integration, supporting seamless function calls.

BDD extensions for Kotest enabling expressive Given/When/Then and Expect tests, type-safe DSL, built-in data-driven row() parameterization, and concise And chaining.

Lightweight audio capture producing canonical 16-bit mono WAV buffers for transcription and AI pipelines, with unified API and extensible event hooks for error handling.

Parses ANSI escape sequences into ratatui-styled text, converting terminal color/style codes (4-, 8-, 24-bit colors; bold, italic, underline, reset) for TUI rendering.

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).

MQTT 3.1.1/5.0 lightweight, configurable client and broker supporting TCP, TLS and WebSockets; subscription/publish APIs, authentication, authorization, packet interception and optional clustering.

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.

Pseudo-terminal interface to spawn and control child processes in a real-terminal environment: execute commands, read/write IO, resize terminal, monitor, interrupt or forcefully terminate processes.

Expose image, audio and video codec utilities: get image info, audio→PCM decoding, Silk encode/decode, PCM duration, video info and first-frame JPEG extraction — handy for QQ protocol work.

Unified file-system abstraction with stream-first APIs for discovering, reading, and writing files, recursive extension-filtered discovery, storage access framework support, stack-based traversal, and lightweight platform detection.

Native TDLib wrapper exposing JSON-based send, receive and execute APIs, automatic native library extraction/loading, JNI and cinterop bridges, prebuilt native cache and build tooling.

Terminal manipulation toolkit: cursor control, rich color/styling (16/256/RGB) and attributes, screen/raw-mode management, event polling (keyboard, mouse, resize), command-pattern ANSI batching.

Ordered B-tree map and set implementing Rust std semantics, preserving upstream behavior and tests; offers stable-order iteration, efficient B-tree operations, and parity-oriented translation.

LR(1) parser generator implementing the lalrpop grammar and architecture, offering a configuration API to process .lalrpop grammars, Cargo-style conventions and code generation.

Wrapper around compiler's procedural-macro API, enabling proc-macro-like token streams outside macros, making macro logic unit-testable; faithful line-by-line transliteration preserving upstream behavior and provenance.

Ergonomic trait-object error type for idiomatic application error handling; attach contextual messages, downcast to concrete error types, capture backtraces, and create errors with concise macros.

Immutable, cheaply-cloneable byte containers and cursored read/write views; typed big- and little-endian numeric access, chaining/limiting adapters, iterator/reader/writer adapters, Result-based safe reads.

Line-by-line transliteration of a mature parser-generator, enabling compact readable grammars, reusable grammar macros, operator and type-inference support, compact defaults, and LR(1)/LALR(1) parsing.

Line-by-line transliteration of an upstream map implementation, delivering faithful feature-parity collections with port-lint headers for provenance tracking and translator guidelines enforcing disciplined ports.

SSE HTTP-body codec decoding server-sent events into event streams and encoding SSE events into HTTP bodies; faithful line-by-line transliteration of upstream Rust implementation.

Retrieves system IANA time‑zone identifier as a string, exposing a tiny API for reliably resolving tz database names with faithful upstream behavior and minimal dependencies.

Line-by-line transliteration of ICU4X decimal internationalization APIs, delivering locale-aware formatting with upstream feature parity and provable provenance via per-file port-lint Rust source headers.

Type-safe, ergonomic flagset declarations with concise APIs for defining, combining, iterating, and converting flags; faithful transliteration of established flagset semantics.

Locate installed executables on PATH across environments; supports regex-based searches, enumeration of multiple matches, and configurable system backends for custom environment handling.

Compact, insertion-order-preserving hash table enabling lookup by key or numerical index, fast iteration, and memory-efficient dense storage; order only changes with removals or swap operations.

Line-by-line transliteration of enum-string utilities — derive string↔enum conversions, iteration, variant metadata, discriminants, counts, and generated helpers for easier enum parsing and display.

Unix shell-style file path pattern matching with recursive globs, iterator-based results, and faithful line-by-line transliteration from an upstream implementation, preserving original behavior and provenance tracking.
