Rovo Language Support for VSCode

Language Server Protocol (LSP) support for Rovo annotations in Rust. Write cleaner, more maintainable OpenAPI-style documentation directly in your Rust code with intelligent IDE support.

Features

• 📖 Hover Documentation - Detailed information for annotations, status codes, and security schemes
• ✅ Real-time Diagnostics - Instant feedback on syntax errors and invalid annotations

• 🎨 Syntax Highlighting - Distinctive colors for annotations, status codes, and more

Quick Start

1. Install the extension from the VSCode Marketplace
2. Open a Rust project with Rovo annotations
3. The extension will automatically install rovo-lsp if not present (requires Cargo)
