mh_lint

mh_lint is a command line tool that is designed to analyze and validate C++ code. It is primarily used in the context of the Mars Helicopter (Ingenuity) project, which is NASA's experimental autonomous aircraft for Mars exploration. The tool performs static analysis on the codebase to ensure adherence to coding standards and to detect potential bugs and issues before runtime.

Using a combination of predefined rules and customizable configurations, mh_lint scans the code to identify common programming mistakes such as unused variables, uninitialized variables, memory leaks, and more. It also checks for compliance with the project's coding guidelines, ensuring consistency across the codebase.

The tool is integrated into the project's build system, allowing developers to easily incorporate it into their development workflow. It provides detailed reports highlighting any detected issues or violations, making it easier to fix them promptly.

With its ability to perform large-scale code analysis, mh_lint helps the development team maintain code quality, improve software reliability, and reduce the risk of potential bugs. It also enforces best practices, promoting clean and maintainable code.

mh_lint supports various C++ standards, including C++11 and C++14. It can handle both individual source files and entire projects, offering flexibility for developers. The tool can be run as a standalone command, integrated into continuous integration (CI) pipelines, or used in conjunction with other development tools.

Overall, mh_lint is a powerful and essential utility for the Mars Helicopter project, ensuring that the codebase remains robust, reliable, and ready for the challenges of operating in the Martian environment.
