Aperçu
GitHub Copilot is the world's most widely adopted AI pair programmer, developed by GitHub in collaboration with OpenAI. Launched in June 2022, it has revolutionized how developers write code by providing intelligent, context-aware code completions directly in your IDE.
Powered by OpenAI Codex (a descendant of GPT-4 trained on billions of lines of code), Copilot doesn't just autocomplete single lines — it can suggest entire functions, generate boilerplate code, write tests, and even explain complex algorithms. With the addition of Copilot Chat, you now have a conversational AI assistant that understands your codebase and can answer questions, debug issues, and refactor code on demand.
Whether you're a seasoned developer looking to boost productivity or a beginner learning to code, GitHub Copilot has become an indispensable tool in the modern development workflow. It supports over 100 programming languages and integrates seamlessly with VS Code, JetBrains IDEs, Neovim, Visual Studio, and Xcode.
Fonctionnalités Clés
Intelligent Code Completion
Context-aware suggestions that understand your code patterns, variable names, and project structure. Suggests entire functions from comments or function signatures.
Copilot Chat
Conversational AI assistant integrated into your IDE. Ask questions about code, get explanations, request refactoring, or debug issues through natural language.
Code from Comments
Write a comment describing what you want, and Copilot generates the implementation. Perfect for quickly scaffolding new features or algorithms.
Multi-file Context
Understands your entire codebase, not just the current file. References related files, types, and functions to provide more accurate suggestions.
CLI Assistant
Copilot for CLI helps you remember command-line syntax, compose complex commands, and understand terminal output with AI-powered assistance.
PR Summaries
Automatically generates pull request descriptions and summaries, saving time on documentation and helping reviewers understand changes quickly.
