### Architecture Overview
The system follows **Clean Architecture** principles with clear separation of concerns:
- **🎯 Entry Point**: Command-line interface handles user input and coordinates operations
- **🏗️ Application Layer**: Core business logic with dependency injection
- **📋 Interface Layer**: Contracts defining behavior without implementation details
- **🔧 Service Layer**: Concrete implementations of parsing and utility services
- **📤 Export Layer**: Factory pattern for format-specific exporters
- **📊 Data Layer**: Domain models representing course structure
## Features
- Parse Articulate Rise JSON data from URLs or local files
- Export to Markdown (.md) format
- Export to HTML (.html) format with professional styling
- Export to Word Document (.docx) format
- Support for various content types:
- Text content with headings and paragraphs
- Lists and bullet points
- Multimedia content (videos and images)
- Knowledge checks and quizzes
- Interactive content (flashcards)
- Course structure and metadata
## Installation
### Prerequisites

### Docker Compose
For local development, you can use the provided `docker-compose.yml`:
```bash
# Build and run with default help command
docker-compose up articulate-parser
# Process files using mounted volumes
docker-compose up parser-with-files
```
### Building Locally
```bash
# Build the Docker image locally
docker build -t articulate-parser:local .
# Run the local image
docker run --rm articulate-parser:local --help
# Build with specific version
docker build --build-arg VERSION=local --build-arg BUILD_TIME=$(date -u +%Y-%m-%dT%H:%M:%SZ) -t articulate-parser:local .
```
### Environment Variables
The Docker image supports the following build-time arguments:

## URL Pattern Recognition
The parser automatically extracts share IDs from Articulate Rise URLs:
- Input: `https://rise.articulate.com/share/N_APNg40Vr2CSH2xNz-ZLATM5kNviDIO#/`
- API URL: `https://rise.articulate.com/api/rise-runtime/boot/share/N_APNg40Vr2CSH2xNz-ZLATM5kNviDIO`
## Error Handling
The parser includes error handling for:
- Invalid URLs or share IDs
- Network connection issues

## Limitations
- Media files (videos, images) are referenced but not downloaded
- Complex interactive elements may be simplified in export
- Styling and visual formatting is not preserved
- Assessment logic and interactivity is lost in static exports
## Performance
- Lightweight with minimal dependencies
- Fast JSON parsing and export
- Memory efficient processing
- No external license requirements
## Future Enhancements
Potential improvements could include:
- [ ] PDF export support
- [ ] Media file downloading
- [x] ~~HTML export with preserved styling~~
- [ ] SCORM package support
- [ ] Batch processing capabilities
- [ ] Custom template support
