## 📦 Installation

```bash
pip install pyspcodeanalyzer
```

## 🛠️ Quick Start

### CLI Usage

Analyze a single file:
```bash
code_analyzer analyze examples/sample.py
```

```

List supported languages:
```bash

```

View metrics information:
```bash
code_analyzer metrics
```

### Python API

```python
from code_analyzer.core.registry import get_analyzer

# Analyze Python code
analyzer = get_analyzer("python")
result = analyzer.analyze_source("""

        if n <= 1:
            return n
        return fibonacci(n-1) + fibonacci(n-2)
""")

print(f"Complexity Score: {result.total_score}/100")
print(f"Complexity Level: {result.classification}")

## 📈 Complexity Scoring System

### 10-Dimension Analysis Framework

Each language is analyzed across these standardized dimensions:

1. **SQL Logic Complexity** - Query complexity, joins, subqueries
2. **Utility Complexity** - Procedures, functions, stored logic
3. **Data Operations** - CRUD operations, data transformations
4. **Control Flow** - Conditional logic, loops, branching
5. **Error Handling** - Exception handling, validation
6. **File I/O & External Integration** - External data sources, APIs
7. **Performance & Optimization** - Indexing, partitioning, caching
8. **Security & Access Control** - Authentication, authorization, encryption
9. **ODS Output Delivery** - Reporting, output generation
10. **Execution Control** - Transaction management, concurrency

### Scoring Scale

- **0-30**: 🟢 **Simple** - Basic operations, minimal complexity
- **31-60**: 🟡 **Medium** - Moderate complexity, some advanced features
- **61-80**: 🟠 **Complex** - Advanced operations, multiple integrations
- **81-100**: 🔴 **Very Complex** - Highly sophisticated, enterprise-grade code

## 🔧 Configuration

### Custom Weights

Create `config.yaml` to customize dimension weights:

```yaml
weights:
  script_size_structure: 10
  dependency_footprint: 10
  analytics_depth: 10
  sql_reporting_logic: 10
  transformation_logic: 10
  utility_complexity: 10
  execution_control: 10
  file_io_external_integration: 10
  ods_output_delivery: 10
  error_handling_optimization: 10

include_cyclomatic: false

classification_thresholds:
  simple: 30
  medium: 60
  complex: 80
  very_complex: 100
```

## 🔌 Extending the Analyzer

Add support for new languages by implementing the `AnalyzerBase` interface:

```python
from code_analyzer.core.analyzer_base import AnalyzerBase
from code_analyzer.core.registry import analyzer_registry

class CustomAnalyzer(AnalyzerBase):
    language = "custom"
    
    def analyze_code(self, code: str) -> AnalysisResult:
        # Implement your analysis logic
        pass
    
    def _calculate_metrics(self, code: str) -> Dict[str, int]:
        # Calculate complexity metrics
        pass

# Register your analyzer
analyzer_registry.register_analyzer("custom", CustomAnalyzer)
```

## 🧪 Testing

Run the test suite:

```bash
# Install development dependencies
pip install -e ".[dev]"

# Run tests
pytest

# Run with coverage
pytest --cov=code_analyzer --cov-report=html

# Run specific test
pytest tests/test_sas_metrics.py -v
```

## 📝 Examples

### Enterprise SAS Analysis
```bash
code_analyzer analyze examples/sample.sas
```

```
