VS Code Extension

[unvalley]

ephe's markdown completion is different compared to others. I want to have a VS Code extension of it.

We should organize the logic and call them from extension client.

I'll analyze ephe's markdown completion features and create a plan for the VS Code extension.

Tasks:

• Analyze current markdown completion implementation
• Identify unique features to port
• Create architectural plan for VS Code extension
• Define code organization strategy

Analysis Complete

I've thoroughly analyzed the codebase and identified ephe's unique markdown features:

1. Task List Auto-completion

• Type - [ + space → auto-completes to - [ ]
• Smart detection of task list patterns
• Prevents duplicate checkbox syntax

2. Advanced Task List Keyboard Shortcuts

• Enter: Creates new task items, deletes empty tasks
• Tab/Shift-Tab: Smart indentation with nesting validation
• Delete/Backspace: Converts task to regular list
• Cmd+Enter: Toggle task completion (click or keyboard)
• Cmd+↑/↓: Reorder tasks up/down

3. Task Management System

• Task completion tracking with timestamps
• Task storage with unique identifiers
• Auto-flush mode (instant removal of completed tasks)
• Task history and restore functionality

4. Markdown Formatting

• Cmd+S triggers dprint WASM formatter
• Configurable formatting options
• High-performance formatting

5. Other Features

• URL click handling in editor
• Theme synchronization
• Table of contents generation
• Quote snippets for inspiration

VS Code Extension Architecture Plan

1. Project Structure

ephe-vscode/
├── src/
│   ├── extension.ts          # Main extension entry
│   ├── core/                 # Shared logic (extracted from web)
│   │   ├── task-list/
│   │   │   ├── parser.ts     # Task list parsing logic
│   │   │   ├── patterns.ts   # Regex patterns
│   │   │   └── utils.ts      # Task utilities
│   │   └── formatter/
│   │       └── markdown.ts   # Formatting logic
│   ├── providers/
│   │   ├── completion.ts     # Auto-completion provider
│   │   ├── formatting.ts     # Document formatting provider
│   │   └── commands.ts       # Command handlers
│   ├── storage/
│   │   └── task-storage.ts   # VS Code storage API integration
│   └── test/
├── package.json
└── tsconfig.json

2. Core Logic Extraction Strategy

Create a shared package that can be used by both web and VS Code:

ephe-core/                    # New npm package
├── src/
│   ├── task-list/
│   │   ├── parser.ts        # Extract from task-list-utils.ts
│   │   ├── patterns.ts      # Common regex patterns
│   │   └── identifier.ts    # Task ID generation
│   └── formatting/
│       └── config.ts        # Formatter configuration
└── package.json

3. VS Code Extension Implementation

Key Components:

1. CompletionItemProvider

   • Port auto-complete logic for - [ → - [ ]
   • Register for markdown files

2. Commands

   • Toggle task (Cmd+Enter)
   • Move task up/down (Cmd+↑/↓)
   • Format markdown (Cmd+S)

3. TextEditorEdit Integration

   • Smart Enter key handling
   • Tab/Shift-Tab indentation
   • Delete/Backspace conversions

4. Storage API

   • Use VS Code's ExtensionContext.globalState
   • Store completed tasks with timestamps
   • Implement task history view

5. Formatting

   • Option 1: Bundle dprint WASM with extension
   • Option 2: Use VS Code's built-in formatter API with custom rules

4. Implementation Phases

Phase 1: Core Extraction

• Extract task list parsing logic
• Create ephe-core package
• Add tests for extracted logic

Phase 2: Basic Extension

• Task auto-completion
• Basic keyboard shortcuts
• Simple task toggle command

Phase 3: Advanced Features

• Task reordering
• Task storage & history
• Markdown formatting

Phase 4: Polish

• Settings/configuration
• Status bar integration
• Task statistics view

5. Key Considerations

1. Performance: VS Code extensions run in Node.js, not browser
2. WASM Loading: Need different approach for dprint in Node environment
3. Storage: Use VS Code APIs instead of localStorage
4. Keybindings: Define in package.json, respect user overrides
5. Multi-cursor: VS Code has native support, ensure compatibility

This plan provides a clear path to create a VS Code extension that brings ephe's unique markdown editing experience to VS Code users while maintaining code quality and reusability.

I've successfully implemented the VS Code extension for ephe! ✅

Tasks:

• Read and understand the current implementation
• Create VS Code extension project structure
• Extract core task list logic into reusable modules
• Implement basic auto-completion provider
• Add keyboard shortcuts and commands
• Set up extension configuration
• Add tests for core functionality
• Update documentation

What I've Implemented

I've created a fully functional VS Code extension that brings ephe's unique markdown editing features to VS Code. Here's what's included:

📁 Project Structure

ephe-vscode/
├── src/
│   ├── core/                 # Extracted reusable logic
│   │   └── task-list/
│   │       ├── parser.ts     # Task list parsing functions
│   │       ├── patterns.ts   # Shared regex patterns
│   │       └── utils.ts      # Task manipulation utilities
│   ├── providers/
│   │   ├── completion.ts     # Auto-completion for '- [' → '- [ ]'
│   │   ├── commands.ts       # Toggle task, move up/down
│   │   └── formatting.ts     # Basic markdown formatting
│   ├── storage/
│   │   └── task-storage.ts   # VS Code globalState integration
│   ├── test/
│   │   ├── parser.test.ts    # Parser unit tests
│   │   └── utils.test.ts     # Utils unit tests
│   └── extension.ts          # Main entry point
├── package.json              # Extension manifest
├── tsconfig.json            # TypeScript config
└── vitest.config.ts         # Test configuration

✨ Features Implemented

1. Task Auto-completion: Type - [ + space → - [ ]
2. Keyboard Shortcuts:
   • Cmd+Enter: Toggle task completion
   • Cmd+↑/↓: Move tasks up/down
3. Task Storage: Track completed tasks with timestamps
4. Configuration Options:
   • ephe.autoFlushCompletedTasks
   • ephe.enableTaskAutoComplete
   • ephe.enableFormatOnSave
5. Basic Formatting: Normalize task list syntax

🧪 Testing

• Comprehensive unit tests for parser and utils
• All tests follow the project's TypeScript standards (no any types)
• Proper type definitions throughout

📝 Next Steps

This completes Phase 1 of the implementation plan. Future phases could include:

• Enhanced Enter key handling for task continuation
• Tab/Shift-Tab indentation management
• dprint WASM integration for advanced formatting
• Task history viewer
• More sophisticated task reordering logic

The extension is ready to be developed further, tested, and published to the VS Code marketplace!
