About:
Pmccabe is a command-line utility that calculates McCabe's cyclomatic complexity metrics for C and C++ source files. It provides detailed analysis of function complexity, file-level metrics, and overall project structure to help identify overly complex code. This tool aids developers in quantifying code maintainability and pinpointing areas that may require refactoring.

Key Features:

Calculates McCabe cyclomatic complexity for C/C++ functions
Reports file-level and project-level complexity metrics
Outputs machine-readable data for integration with other tools
Supports analysis of multiple files in a single run

Use Cases:

Identifying high-risk functions during code reviews
Establishing complexity thresholds in CI/CD pipelines
Generating complexity reports for legacy codebases

Alternatives:

lizard – Lizard supports multiple languages beyond C/C++ and offers more detailed metrics like token count and parameter count.
radon – Radon is Python-specific but provides similar complexity analysis (cyclomatic and maintainability index) for Python code.
