This repository is a Tampermonkey/Greasemonkey userscript that translates the GitHub web interface into Chinese (Simplified and Traditional). It works by loading a dictionary file containing static translations and regex rules, then applying them to the DOM on page load and dynamically via MutationObserver. It includes a sophisticated patch for GitHub's React-based GlobalNav header that carefully times translations to avoid conflicts with React rendering. The repository also contains a VS Code extension that injects the script into VS Code's integrated browser via Chrome DevTools Protocol, enabling translation within the IDE. The codebase is well-structured with clear separation of configuration, state management, and translation logic. It includes a comprehensive test suite for regression testing. The project is actively maintained with frequent updates to keep pace with GitHub's UI changes.
