The mviewer repository is a Rust-based application for viewing and exporting Marmoset .mview scene files. It features a dual-mode interface: launching a GUI (using tao/wry embedded webview) for interactive preview when no arguments are provided, or running in CLI mode for batch conversion when arguments are given. The GUI loads a local HTTP server to serve an embedded, forked Marmoset JavaScript viewer that renders scenes with visual parity to Marmoset Toolbag. The core Rust logic handles loading the proprietary .mview archive format, extracting scene data (meshes, materials, animations, cameras, lights, textures), and exporting to glTF/GLB/OBJ formats. The application demonstrates strong modularity with clear separation between archive parsing, data processing, export pipelines, and GUI integration. While the embedded JavaScript viewer introduces some maintenance considerations due to its forked nature, the Rust components exhibit high reusability and craftsmanship, particularly in handling complex binary formats and data transformations.
Bull Exporter is a Prometheus metrics exporter for Bull queues running on Redis. It provides an HTTP server (default port 9538) that exposes queue state metrics (waiting, active, delayed, failed, completed counts) and job duration summaries. It supports automatic queue discovery by scanning Redis keys, and can also be run in one-shot mode to print metrics to stdout. The application is built with Express, Bull, ioredis, and prom-client, and is packaged as a Docker image. The codebase is well-structured with TypeScript, strict compiler options, comprehensive unit tests using Jest and real Redis, and CI/CD pipelines (Travis CI and CircleCI). However, the project has been stale since October 2020, uses very outdated dependencies (Node.js 10, TypeScript 3.9, old prom-client), and has no recent maintenance activity. The code quality is solid for its time but suffers from technical drift.
