Features

Complexity Metrics

• Cyclomatic Complexity (McCabe): Measures the number of linearly independent paths through code
• Cognitive Complexity: Measures how difficult it is to understand the code's control flow
• Halstead Metrics:
  • Volume: Measures the size of the implementation
  • Difficulty: Indicates how hard the code is to understand
  • Effort: Estimates the effort required to maintain the code
• Maintainability Index: A composite metric indicating overall maintainability (0-100 scale)
• Lines of Code: Physical lines of code per function

Installation

1. Clone the repository:

git clone https://github.com/aman/code-complexity-viz
cd code-complexity-viz

2. Install dependencies:

go mod tidy

3. Run the server:

go run main.go

4. Open http://localhost:8080 in your browser

Usage

1. Upload a Go source file using the web interface
2. Click "Analyze" to process the file
3. View the visualization of complexity metrics
4. Use the dropdown to switch between different metrics
5. Hover over bars to see detailed metrics for each function

Limitations

• Maximum file size: 5MB
• Only analyzes .go files
• Functions must be syntactically valid Go code
