# lumide_cpp
2+
3+
[![pub package](https://img.shields.io/pub/v/lumide_cpp.svg)](https://pub.dev/packages/lumide_cpp) [![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://opensource.org/licenses/MIT) [![Powered by SoFluffy](https://img.shields.io/badge/Powered%20by-SoFluffy-orange)](https://sofluffy.io)
4+
5+
The official C/C++ extension for [Lumide IDE](https://lumide.dev).
6+
7+
`lumide_cpp` provides comprehensive C and C++ language support for Lumide using the `clangd` language server.
8+
9+
## Features
10+
11+
### 🛠 Language Support
12+
- **IntelliSense**: Intelligent code completions and suggestions.
13+
- **Diagnostics**: Real-time error and warning highlighting.
14+
- **Navigation**: Go-to-definition, find-references, and symbol search.
15+
- **Formatting**: Automated code formatting via `clangd`.
16+
17+
### ⚡ Performance
18+
- **Low Latency**: Directly interacts with the `clangd` binary for maximum responsiveness.
19+
- **Resource Efficient**: Only spawns the language server when C/C++ files are active.
20+
21+
## Commands
22+
23+
Access these via the Command Palette (`Cmd+Shift+P` / `Ctrl+Shift+P`):
24+
25+
| Command ID | Title | Description |
26+
|---|---|---|
27+
| `lumide_cpp.restartLsp` | **C/C++: Restart Language Server** | Restart the `clangd` process |
28+
29+
## Requirements
30+
31+
- **Clangd**: Part of LLVM/Clang. Must be installed and available in your system `PATH`.
32+
- **macOS**: `xcode-select --install`
33+
- **Linux**: `sudo apt install clangd`
34+
- **Windows**: Install via LLVM or Visual Studio Installer.
