## Publishing Preparation

The project is now ready to publish to PyPI. Publishing steps:

1. **Install build tools**
   ```bash
   pip install build twine
   ```

2. **Build package**
   ```bash
   python -m build
   ```

3. **Test installation**
   ```bash
   pip install dist/aiecs-1.0.0-py3-none-any.whl
   ```

4. **Upload to TestPyPI** (recommended to test first)
   ```bash
   python -m twine upload --repository testpypi dist/*
   ```

5. **Upload to PyPI**
   ```bash
   python -m twine upload dist/*
   ```

## Usage Instructions

After installation, users can:

1. **Use as a library**
   ```python
   from aiecs import AIECS
   from aiecs.domain.task.task_context import TaskContext
   ```

2. **Run service**
   ```bash
   aiecs  # or python -m aiecs
   ```

3. **Run weasel patch** (if automatic patch fails)
   ```bash
   aiecs-patch-weasel
   ```

4. **Download NLP data packages** (if automatic download fails)
   ```bash
   # Use Python script command (recommended)
   aiecs-download-nlp-data
   
   # Or use shell script
   ./aiecs/scripts/setup_nlp_data.sh
   
   # Only verify installed data packages
   ./aiecs/scripts/setup_nlp_data.sh --verify
   ```

## Important Notes

1. Users need to configure environment variables (.env file) to use normally
2. PostgreSQL and Redis services are required for full operation
3. Weasel patch will automatically attempt to execute during installation
4. NLP data packages (NLTK stopwords and spaCy en_core_web_sm) will automatically download during installation
5. **Image Tool requires system-level Tesseract OCR to use OCR functionality**
6. **Java Environment and Apache Tika (Optional Dependency)**:
   - Office Tool's text extraction functionality uses Apache Tika as a universal fallback solution
   - Tika supports text extraction from 1000+ document formats (including legacy Office formats)
   - Requires Java Runtime Environment (JRE) 8+ to use
   - If Java environment is not available, Tika-related tests will be automatically skipped, not affecting other functionality
   - Recommended to install Java in enterprise environments or when processing multiple document formats
7. Project supports Python 3.10-3.12

## Automation Features

### NLP Data Package Management
- **Auto-Download**: Automatically downloads NLP data packages required by classfire_tool during installation
  - NLTK stopwords, punkt, and other data packages
  - spaCy English model en_core_web_sm (required)
  - spaCy Chinese model zh_core_web_sm (optional)
- **Multiple Execution Methods**:
  - Python script: `aiecs-download-nlp-data`
  - Shell script: `./aiecs/scripts/setup_nlp_data.sh`
  - Verification mode: `./aiecs/scripts/setup_nlp_data.sh --verify`
- **Advanced Features**:
  - Automatic virtual environment detection and activation
  - Dependency integrity checking
  - Download progress and status logging
  - Post-installation verification tests
  - Intelligent detection of existing data packages
  - Timeout protection (prevents long hangs)
- **Error Handling**: Download failures do not block the entire installation process, detailed logs are generated

### Java/Tika Integration Management
- **Function Positioning**: Apache Tika serves as Office Tool's universal text extraction fallback solution
- **Supported Formats**: 
  - Dedicated library processing: DOCX, PPTX, XLSX (using python-docx/python-pptx/pandas)
  - PDF documents (using pdfplumber)
  - Image OCR (using pytesseract)
  - **Tika-processed formats**: Legacy Office (.doc/.xls/.ppt), RTF, ODF, e-books, and 1000+ formats
- **Environment Detection**:
  - Automatically detects Java runtime environment
  - Gracefully skips during testing (if Java unavailable)
  - Provides degradation handling at runtime
- **Deployment Recommendations**:
  - **Development Environment**: Java optional, convenient for complete testing
  - **Production Environment**: Decide based on document processing requirements
  - **Docker Deployment**: Provides both Java-enabled and pure Python image options
- **Error Handling**: Tika unavailability does not affect other document processing functionality, warning logs are recorded

## Java Environment Configuration Guide

### Installing Java Runtime Environment

#### Linux (Ubuntu/Debian)
```bash
# Install OpenJDK 11 (recommended)
sudo apt update
sudo apt install openjdk-11-jre-headless

# Or install OpenJDK 8 (minimum requirement)
sudo apt install openjdk-8-jre-headless

# Verify installation
java -version
```

#### Linux (CentOS/RHEL/Fedora)
```bash
# CentOS/RHEL
sudo yum install java-11-openjdk-headless

sudo dnf install java-11-openjdk-headless

# Verify installation
java -version
```

#### macOS
```bash

### Verifying Tika Functionality

After installing Java, you can verify if Tika functionality works correctly:

```python
from aiecs.tools.task_tools.office_tool import OfficeTool

# Create tool instance
tool = OfficeTool()

# Test Tika text extraction (using any document file)
try:
    text = tool.extract_text("path/to/your/document.doc")
    print("Tika functionality working correctly")
except Exception as e:
    print(f"Tika unavailable: {e}")
```
