-## 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 -- **XLSX**: Spreadsheet generation for Excel/ODS export -- **electron-builder**: Application packaging -- **Custom Storage**: File-based storage system for settings persistence - -## 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 for document exports -- Supports multiple output formats (HTML, PDF, DOCX, LaTeX, RTF, ODT, EPUB, PPTX, ODP) -- Spreadsheet export using XLSX library for table data -- Import functionality for converting documents to markdown -- Maintains original file structure -- Shows error messages if Pandoc not installed - -### Table Creation Helper -- Interactive table generator in toolbar -- Prompts for row and column count -- Generates properly formatted markdown tables -- Includes headers and separator rows -- Automatically inserts at cursor position - -### Document Conversion Menu -- Separate Convert menu for cross-format operations -- Import documents from various formats to markdown -- Convert current file to different formats -- Supports presentations with proper slide-level formatting -- Error handling for missing Pandoc installation - -## 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, Table Creation -3. Preview Toggle: Show/hide preview pane -4. Theme Switching: Test all five themes -5. Export Functions: Test each export format including PowerPoint and spreadsheets -6. Import/Conversion: Test document import and format conversion -7.
