## Intro

Visual Studio Code is Microsoft open-source code editor built on the Electron framework. First released in 2015 at Build conference, VS Code quickly became the dominant code editor, overtaking Sublime Text, Atom, and eventually Notepad++. Combines lightweight startup and extensibility with a rich feature set: IntelliSense, integrated debugging, Git, terminal, and a 60,000+ extension marketplace.

- **Repo**: https://github.com/microsoft/vscode
- **Stars**: 183K+
- **Language**: TypeScript
- **License**: MIT (source) / proprietary (Microsoft branded build)

## What VS Code Does

- **IntelliSense** — smart completions with type info
- **Debugging** — launch and debug Node, Python, Go, C++, etc.
- **Git integration** — inline diff, stage, commit, push
- **Extensions** — 60,000+ on marketplace
- **Integrated terminal** — shell inside editor
- **Multi-cursor** — Ctrl+D to add cursor to next match
- **Live Share** — real-time pair programming
- **Remote development** — SSH, containers, WSL, Codespaces
- **Jupyter notebooks** — built-in support
- **Task runners** — define tasks.json for project commands
- **Workspace settings** — per-project and user config

## Architecture

Electron shell + Monaco editor (the web-based component also used in monaco-editor). Language features delegated to Language Servers via the Language Server Protocol (LSP, originally invented for VS Code). Extensions run in a separate Extension Host process for isolation.

## Self-Hosting

The source code at `microsoft/vscode` is MIT-licensed, but the branded "Visual Studio Code" binary includes proprietary telemetry and the Microsoft Marketplace. Open-source builds:
- **VSCodium** — no telemetry, community build
- **Code - OSS** — the raw open-source build
- **Cursor** — AI-first VS Code fork
- **Windsurf** — another AI-first fork

## Key Features

- Free and open source (core)
- Cross-platform
- Extensive marketplace
- LSP-based language features
- Integrated Git, terminal, debugger
- Remote development (SSH, containers, WSL)
- Live Share
- Profiles (per-language setups)
- Jupyter notebook support
- Settings Sync

## Comparison

| Editor | Extensibility | Remote Dev | AI Focus |
|---|---|---|---|
| VS Code | Marketplace | Best | Copilot + extensions |
| Cursor | VS Code fork | Same | AI-first |
| Windsurf | VS Code fork | Same | AI-first |
| JetBrains IDEs | Plugins | Gateway | AI Assistant |
| Zed | Native | Yes | Built-in |
| Sublime Text | Python packages | Limited | Via plugins |

## 常见问题 FAQ

**Q: VS Code 和 VS Codium 区别？**
A: VS Codium 是 Microsoft VS Code 源码去掉商标和遥测后的重编译。功能相同，隐私更好，但用不了 MS Marketplace（可换 Open VSX Registry）。

**Q: Remote Development 有哪些？**
A: Remote - SSH（远程服务器）、Dev Containers（Docker 容器）、WSL（Windows 子系统）、Codespaces（托管）。编辑器本地跑，语言服务和文件在远程。

**Q: 和 JetBrains 比？**
A: VS Code 启动快、免费、扩展多、语言通用；JetBrains 特定语言（Java/Kotlin/Go/Rust）更深入、重构更智能。
