Lurix: Codeforces IDE & Auto-Runner

Practice Without Friction

Lurix: Practice Without Friction. Lurix is a comprehensive, professional-grade Chrome Extension designed to integrate a native, IDE-level competitive programming environment directly into Codeforces. By consolidating the code editor, terminal, and browser into a single unified interface, Lurix eliminates context switching and streamlines the problem-solving workflow. CORE IDE ENGINE (POWERED BY MONACO) Lurix injects the Monaco Editor engine (the same architecture that powers VS Code) directly into Codeforces problem pages. - Intellisense & Snippets: Includes instantaneous, rich autocompletion. Standard typing shortcuts expand into comprehensive competitive programming boilerplate (e.g., C++ headers, standard namespaces, loops, and fast I/O configurations). - Native Keybindings: Full, native support for Vim and Emacs workflows directly within the browser environment. - Local-First Caching: Code is cached locally in real-time. In the event of an accidental tab closure or page refresh, your progress is automatically preserved and instantly restored. INSTANT LOCAL EXECUTION - Zero-Queue Run Engine: Test cases are executed using a custom local API runner, completely bypassing the standard Codeforces server queue for instantaneous feedback. - Multi-Test Auto-Runner: Lurix automatically scrapes all sample test cases from the active problem page and evaluates your code against all cases simultaneously, outputting exact expected-versus-actual diffing. - Failed Test Case Fetcher: Upon a rejected submission, Lurix automatically extracts the hidden failed test case data and injects it straight into your IDE for immediate debugging. PREMIUM INTERFACE OVERHAUL The standard Codeforces interface is completely modernized. - Problemset tables feature a clean, minimal aesthetic with responsive hover states. - Problem tags are encased in distinct, highly readable containers. - Difficulty ratings are dynamically color-coded to provide immediate visual hierarchy. - Solved and failed problems are softly highlighted to give users a clear, bird's-eye view of their historical progress. COMPETITIVE MODE A dedicated focus toggle hooks into the browser's Fullscreen API, hiding the operating system and browser UI to eliminate external distractions. A precise, monospaced live stopwatch begins ticking the moment you enter Competitive Mode to facilitate exact solve-time tracking. Built for competitive programmers, Lurix delivers the seamless, modern coding experience that the Codeforces platform has always needed.
