Editor Integration Overview

Radium provides seamless bidirectional integration with popular editors through extensions and clipboard mode, enabling AI-assisted development without leaving your editor.

Integration Methods

Radium offers three integration methods, each with different levels of functionality:

1. Neovim Extension (radium-nvim)

Best for: Neovim users who want full-featured integration

• Direct commands in Neovim (:RadiumSendSelection, :RadiumChat, :RadiumApplyBlock)
• Automatic context injection (file path, language, surrounding code)
• Diff preview before applying changes
• Integrated chat sessions

Installation:

rad extension install radium-nvim

Documentation: Neovim Integration Guide

2. VS Code Extension (radium-vscode)

Best for: VS Code users who want native IDE integration

• Command palette integration
• Built-in diff viewer
• Integrated terminal for chat
• Workspace awareness

Installation:

rad extension install radium-vscode

Documentation: VS Code Integration Guide

3. Clipboard Mode

Best for: Users of any editor or when extensions aren't available

• Works with any editor via copy/paste
• File path annotation support
• Automatic language detection
• No extension installation required

Usage:

rad clipboard send    # Send code from clipboard to Radium
rad clipboard receive # Get processed code to clipboard

Documentation: Clipboard Mode Guide

Quick Start

1. Install Radium CLI (if not already installed)
2. Choose your integration method based on your editor
3. Install the extension (for Neovim or VS Code) or use clipboard mode
4. Start using - select code and send to Radium!

Architecture

All integration methods leverage:

• Extension System: Radium's extension infrastructure for hooks and commands
• Hook System: BeforeTool and AfterTool hooks for context injection and result processing
• CLI Commands: rad step and rad chat for agent communication

See Architecture Documentation for technical details.
