Analysis Module + +A comprehensive code analysis module for the Codegen-on-OSS project that provides a unified interface for analyzing codebases. + +## Overview + +The Analysis Module integrates various specialized analysis components into a cohesive system, allowing for: + +- Code complexity analysis +- Import dependency analysis +- Documentation generation +- Symbol attribution +- Visualization of module dependencies +- Comprehensive code quality metrics + +## Components + +The module consists of the following key components: + +- **CodeAnalyzer**: Central class that orchestrates all analysis functionality +- **Metrics Integration**: Connection with the CodeMetrics class for comprehensive metrics +- **Import Analysis**: Tools for analyzing import relationships and cycles +- **Documentation Tools**: Functions for generating documentation for code +- **Visualization**: Tools for visualizing dependencies and relationships + +## Usage + +### Basic Usage + +```python +from codegen import Codebase +from codegen_on_oss.analysis.analysis import CodeAnalyzer +from codegen_on_oss.metrics import CodeMetrics + +# Load a codebase +codebase = Codebase.from_repo("owner/repo") + +# Create analyzer instance +analyzer = CodeAnalyzer(codebase) + +# Get codebase summary +summary = analyzer.get_codebase_summary() +print(summary) + +# Analyze complexity +complexity_results = analyzer.analyze_complexity() +print(f"Average cyclomatic complexity: {complexity_results['cyclomatic_complexity']['average']}") + +# Analyze imports +import_analysis = analyzer.analyze_imports() +print(f"Found {len(import_analysis['import_cycles'])} import cycles") + +# Create metrics instance +metrics = CodeMetrics(codebase) + +# Get code quality summary +quality_summary = metrics.get_code_quality_summary() +print(quality_summary) +``` + +### Web API + +The module also provides a FastAPI web interface for analyzing repositories: + +```bash +# Run the API server +python -m codegen_on_oss.analysis.analysis +``` + +Then you can make POST requests to `/analyze_repo` with a JSON body: + +```json +{ + "repo_url": "owner/repo" +} +``` + +## Key Features + +### Code Complexity Analysis + +- Cyclomatic complexity calculation +- Halstead complexity metrics +- Maintainability index +- Line metrics (LOC, LLOC, SLOC, comments) + +### Import Analysis + +- Detect import cycles +- Identify problematic import loops +- Visualize module dependencies + +### Documentation Generation + +- Generate documentation for functions +- Create MDX documentation for classes +- Extract context for symbols + +### Symbol Attribution + +- Track symbol authorship +- Analyze AI contribution + +### Dependency Analysis + +- Create dependency graphs +- Find central files +- Identify dependency cycles + +## Integration with Metrics + +The Analysis Module is fully integrated with the CodeMetrics class, which provides: + +- Comprehensive code quality metrics +- Functions to find problematic code areas +- Dependency analysis +- Documentation generation + +## Example + +See `example.py` for a complete demonstration of the analysis module's capabilities. + diff --git
