+# Codegen 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.

-# Codegen Analysis Module
+# Code Analysis Module with Error Context
-A comprehensive code analysis module for the Codegen-on-OSS project that provides a unified interface for analyzing codebases.
+This module provides robust and dynamic code analysis capabilities with a focus on error detection and contextual error information.
## Overview
-The Analysis Module integrates various specialized analysis components into a cohesive system, allowing for:
+The code analysis module consists of several components:
-- Code complexity analysis
-- Import dependency analysis
-- Documentation generation
-- Symbol attribution
-- Visualization of module dependencies
-- Comprehensive code quality metrics
+1. **CodeAnalyzer**: The main class that integrates all analysis components and provides a unified interface.
+2. **ErrorContextAnalyzer**: A specialized class for detecting and analyzing errors in code.
+3. **CodeError**: A class representing an error in code with detailed context information.
+4. **API Endpoints**: FastAPI endpoints for accessing the analysis functionality.
-## Components
+## Features
-The module consists of the following key components:
+### Code Structure Analysis
-- **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
+- Analyze codebase structure and dependencies
+- Generate dependency graphs for files and symbols
+- Analyze import relationships and detect circular imports
+- Get detailed information about files, functions, classes, and symbols
+
+### Error Detection and Analysis
+
+- Detect syntax errors, type errors, parameter errors, and more
+- Analyze function parameters and return statements for errors
+- Detect undefined variables and unused imports
+- Find circular dependencies between symbols
+- Provide detailed context information for errors
+
+### API Endpoints
+
+- `/analyze_repo`: Analyze a repository and return various metrics
+- `/analyze_symbol`: Analyze a symbol and return detailed information
+- `/analyze_file`: Analyze a file and return detailed information
+- `/analyze_function`: Analyze a function and return detailed information
+- `/analyze_errors`: Analyze errors in a repository, file, or function
+
+## Error Types
+
+The module can detect the following types of errors:
+
+- **Syntax Errors**: Invalid syntax in code
+- **Type Errors**: Type mismatches in expressions
+- **Parameter Errors**: Incorrect function parameters
+- **Call Errors**: Incorrect function calls
+- **Undefined Variables**: Variables used without being defined
+- **Unused Imports**: Imports that are not used in the code
+- **Circular Imports**: Circular dependencies between files
+- **Circular Dependencies**: Circular dependencies between symbols
## Usage
-### Basic Usage
+### Using the CodeAnalyzer
```python
from codegen import Codebase
from codegen_on_oss.analysis.analysis import CodeAnalyzer
-from codegen_on_oss.metrics import CodeMetrics
-# Load a codebase
+# Create a codebase from a repository
codebase = Codebase.from_repo("owner/repo")
-# Create analyzer instance
+# Create an analyzer
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 errors in the codebase
+errors = analyzer.analyze_errors()
-# Analyze imports
-import_analysis = analyzer.analyze_imports()
-print(f"Found {len(import_analysis['import_cycles'])} import cycles")
+# Get detailed error context for a function
+function_errors = analyzer.get_function_error_context("function_name")
-# Create metrics instance
-metrics = CodeMetrics(codebase)
-
-# Get code quality summary
-quality_summary = metrics.get_code_quality_summary()
-print(quality_summary)
+# Get detailed error context for a file
+file_errors = analyzer.get_file_error_context("path/to/file.py")
```
-### Web API
-
-The module also provides a FastAPI web interface for analyzing repositories:
+### Using the API
```bash
-# Run the API server
-python -m codegen_on_oss.analysis.analysis
+# Analyze a repository
+curl -X POST "http://localhost:8000/analyze_repo" \
+ -H "Content-Type: application/json" \
+ -d '{"repo_url": "owner/repo"}'
+
+# Analyze errors in a function
+curl -X POST "http://localhost:8000/analyze_function" \
+ -H "Content-Type: application/json" \
+ -d '{"repo_url": "owner/repo", "function_name": "function_name"}'
+
+# Analyze errors in a file
+curl -X POST "http://localhost:8000/analyze_file" \
+ -H "Content-Type: application/json" \
+ -d '{"repo_url": "owner/repo", "file_path": "path/to/file.py"}'
```
-Then you can make POST requests to `/analyze_repo` with a JSON body:

-## Key Features
-
-### Code Complexity Analysis
-
-- Cyclomatic complexity calculation
-- Halstead complexity metrics
-- Maintainability index
-- Line metrics (LOC, LLOC, SLOC, comments)
-
-### Import Analysis
+## Implementation Details
-- Detect import cycles
-- Identify problematic import loops
-- Visualize module dependencies
+### ErrorContextAnalyzer
-### Documentation Generation
+The `ErrorContextAnalyzer` class is responsible for detecting and analyzing errors in code. It uses various techniques to detect errors, including:
-- Generate documentation for functions
-- Create MDX documentation for classes
-- Extract context for symbols
+- **AST Analysis**: Parsing the code into an abstract syntax tree to detect syntax errors and undefined variables
+- **Graph Analysis**: Building dependency graphs to detect circular imports and dependencies
+- **Pattern Matching**: Using regular expressions to detect potential type errors and other issues
-### Symbol Attribution
+### CodeError
-- Track symbol authorship
-- Analyze AI contribution
+The `CodeError` class represents an error in code with detailed context information. It includes:
-### Dependency Analysis
+- **Error Type**: The type of error (syntax, type, parameter, etc.)
+- **Message**: A descriptive message explaining the error
+- **Location**: The file path and line number where the error occurs
+- **Severity**: The severity of the error (critical, high, medium, low, info)
+- **Context Lines**: The lines of code surrounding the error
+- **Suggested Fix**: A suggested fix for the error
-- Create dependency graphs
-- Find central files
-- Identify dependency cycles
+## Running the API Server
-## Integration with Metrics
+To run the API server locally:
-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
+```bash
+cd codegen-on-oss
+python -m codegen_on_oss.analysis.analysis
+```
-See `example.py` for a complete demonstration of the analysis module's capabilities.
+The server will be available at `http://localhost:8000`.
