cli-chess is a terminal-based chess application that supports playing online via Lichess.org and offline against the Fairy-Stockfish engine. It features a modular MVP (Model-View-Presenter) architecture with clear separation of concerns across core game logic, reusable UI components (board, move list, chat, clock), menu systems, and API integration. The application supports all Lichess chess variants, includes features like premoves, takebacks, draw offers, chat, blindfold mode, unicode pieces, custom theming, and PGN export. Entry point is src/cli_chess/__main__.py, with gameplay driven by user input flowing through presenters to models, which update views via an event system. External dependencies include python-chess for board logic, berserk for Lichess API, and prompt-toolkit for the terminal UI.
This repository is a comprehensive Flutter learning project that simulates an e-commerce management system (merchant order, goods, statistics, shop settings, account/withdrawal). It showcases a wide array of Flutter techniques: MVP architecture with a base presenter pattern, provider state management, custom animations (Lottie, ripple, scratch card), custom chart widgets (bezier and pie charts), complex scrolling (NestedScrollView, custom scroll view), dark mode, localization (English/Chinese), QR code scanning, image picking, AMap integration, and more. The application contains multiple modules connected via fluro routing, with Dio for networking (targeting a mock GitHub API). While the codebase demonstrates many patterns and includes a significant test suite (unit, integration, accessibility), it is primarily a personal learning project and contains several signs of incomplete migration, mock-only behaviors, workarounds, and copied/vendored code. As such, it serves as a rich educational reference for Flutter development but is not production-ready without refinement.
