# Pan Converter
## Overview
Pan Converter is a cross-platform desktop application for editing and converting Markdown files using Pandoc. It features a rich markdown editor with live preview, multiple themes, and support for exporting to various formats.
## Features
- **Markdown Editor**: Full-featured editor with syntax highlighting
- **Live Preview**: Real-time preview of your markdown content
- **Multiple Themes**: Light, Dark, Solarized, Monokai, and GitHub themes
- **Format Conversion**: Export to HTML, PDF, DOCX, LaTeX, RTF, ODT, and EPUB using Pandoc
- **Cross-Platform**: Runs on Windows, macOS, and Linux
- **Auto-Save**: Automatic saving every 30 seconds
## Requirements
- **Pandoc**: Must be installed on the system for export functionality
- Ubuntu/Debian: `sudo apt-get install pandoc`
- macOS: `brew install pandoc`
- Windows: Download from https://pandoc.org/installing.html
## Development Setup
### Prerequisites
- Node.js (v14 or higher)
- npm or yarn
- Pandoc (for export features)
### Installation
```bash
# Clone the repository
git clone <repository-url>
cd pan-converter
# Install dependencies
npm install
# Generate icons
npm run generate-icons
# Start the application
npm start
```
## Building
### Build for Current Platform
```bash
npm run build
```
### Build for Specific Platforms
```bash
# Windows
npm run build:win
# macOS
npm run build:mac
# Linux (generates .deb, .AppImage, and .snap)
npm run build:linux
```
### Build for All Platforms
```bash
npm run dist:all
```
## Project Structure
```
pan-converter/
├── src/
│ ├── main.js # Main process
│ ├── renderer.js # Renderer process
│ ├── index.html # Main window HTML
│ └── styles.css # Application styles
├── assets/
│ ├── icon.svg # Source icon
│ └── icon.png # Generated icons
├── scripts/
│ └── generate-icons.js # Icon generation script
├── package.json # Project configuration
└── CLAUDE.md # This file
```
## Architecture
### Main Process (`src/main.js`)
- Manages application lifecycle
- Creates and manages windows
- Handles file operations
- Manages menu bar
- Communicates with renderer via IPC
### Renderer Process (`src/renderer.js`)
- Handles UI interactions
- Manages editor state
- Renders markdown preview
- Handles theme switching
- Communicates with main process via IPC
### Key Libraries
- **Electron**: Desktop application framework
- **marked**: Markdown parsing
- **highlight.js**: Syntax highlighting
- **DOMPurify**: HTML sanitization
- **electron-store**: Persistent storage
- **electron-builder**: Application packaging
## Features Implementation
### Markdown Editor
- Uses native textarea with custom styling
- Supports common markdown shortcuts via toolbar
- Tab key inserts 4 spaces for code indentation
- Auto-save every 30 seconds when content changes
### Live Preview
- Updates in real-time as you type
- Sanitized HTML output for security
- Syntax highlighting for code blocks
- GitHub-flavored markdown support
### Theme System
- Themes stored in user preferences
- Applied via CSS classes on body element
- Persists across application restarts
- Five built-in themes
### Export System
- Uses Pandoc command-line tool
- Supports multiple output formats
- Maintains original file structure
- Shows error messages if Pandoc not installed
## Platform-Specific Branches
The repository maintains separate branches for platform-specific customizations:
- `master`: Main development branch
- `linux`: Linux-specific configurations
- `macos`: macOS-specific configurations
- `windows`: Windows-specific configurations
## Debian Package
The application can be built as a `.deb` package for Debian-based systems:
```bash
npm run build:linux
```
The generated `.deb` file will:
- Install to `/opt/pan-converter`
- Create desktop entry for application menu
- Set up proper file associations
- Declare Pandoc as dependency
## Testing
### Manual Testing
1. File Operations: New, Open, Save, Save As
2. Editor Features: Bold, Italic, Headings, Links, Code, Lists, Quotes
3. Preview Toggle: Show/hide preview pane
4. Theme Switching: Test all five themes
5. Export Functions: Test each export format
6. Auto-save: Verify 30-second auto-save works
### Platform Testing
Test on:
- Windows 10/11
- macOS 11+ (Big Sur and later)
- Ubuntu 20.04+, Debian 11+
## Known Issues
- ICO and ICNS icons need manual conversion from PNG
- Pandoc must be installed separately
- Large files may cause performance issues
## Future Enhancements
- [ ] Add spell checking
- [ ] Implement find and replace
- [ ] Add custom CSS for preview
- [ ] Support for markdown extensions
- [ ] Plugin system for custom exporters
- [ ] Cloud sync capabilities
- [ ] Collaborative editing

# Push Instructions for Pan Converter
## Prerequisites
1. Create a new repository on GitHub: https://github.com/new
- Repository name: `pan-converter`
- Keep it empty (no README, .gitignore, or license)
- Make it public or private as desired
2. Set up authentication:
- **Option A - SSH Key** (Recommended):
```bash
# Check if you have SSH key
ls -la ~/.ssh/id_rsa.pub
# If not, generate one:
ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
# Add to GitHub: Settings > SSH and GPG keys > New SSH key
cat ~/.ssh/id_rsa.pub
```
- **Option B - Personal Access Token**:
- Go to GitHub Settings > Developer settings > Personal access tokens
- Generate new token with 'repo' scope
- Save the token securely
## Push Commands
### Using SSH (Recommended)
```bash
# Set SSH remote
git remote set-url origin git@github.com:amitwh/pan-converter.git
# Push all branches
git push -u origin master
git push origin linux
git push origin macos
git push origin windows
```
### Using HTTPS with Token
```bash
# Set HTTPS remote
git remote set-url origin https://github.com/amitwh/pan-converter.git
# Push all branches (you'll be prompted for username and token)
git push -u origin master
git push origin linux
git push origin macos
git push origin windows
# When prompted:
# Username: amitwh
# Password: [paste your Personal Access Token]
```
### Using GitHub CLI (if installed)
```bash
# Login to GitHub CLI
gh auth login
# Create repo and push
gh repo create pan-converter --public --source=. --remote=origin --push
```
## Automated Script
```bash
# Run the provided script
./push-to-github.sh
```
## Verify Success
After pushing, verify at: https://github.com/amitwh/pan-converter
You should see:
- 4 branches (master, linux, macos, windows)
- All project files
- Complete commit history
## Troubleshooting
### Authentication Failed
- For SSH: Ensure your SSH key is added to GitHub
- For HTTPS: Use Personal Access Token, not password
- Check token has 'repo' scope
### Repository Not Found
- Ensure repository exists on GitHub
- Check spelling: `pan-converter`
- Verify you're logged into the correct GitHub account
### Permission Denied
- Check repository ownership
- Ensure you have write access
- Verify authentication method is correct
