[Amiya167]

Overview

Implement a VS Code-style plugin/extension system for Logos IDE that allows third-party developers to extend the IDE's functionality.

Design Document

See docs/plugin-system-design.md for the complete design specification.

Key Features

• Extension Host: Isolated process for running extensions safely
• Extension API: VS Code-compatible API including window, editor, workspace, commands, languages
• Activation Events: Support for lazy loading with events like onLanguage, onCommand, workspaceContains
• Sandboxed Execution: Secure environment to prevent malicious code
• Permission System: Explicit permission declarations for file system, network, terminal access

Implementation Phases

Phase 1: Infrastructure

• Extension Host process
• IPC communication between main process and Extension Host
• Plugin loader
• Basic API framework

Phase 2: Core API

• logos.window API
• logos.editor API
• logos.workspace API
• logos.commands API

Phase 3: Language Support

• logos.languages API
• LSP integration interface
• Syntax highlighting extension point

Phase 4: UI Extensions

• Sidebar view extensions
• Status bar extensions
• Menu extensions
• Webview API

Phase 5: Plugin Marketplace

• Marketplace API design
• Plugin search and installation
• Update mechanism
• Ratings and reviews

Security Considerations

• Extensions run in isolated process
• Node.js vm module for sandboxing
• Limited file system and network access
• Code signing for marketplace extensions
