gnu-complexity for Mac

gnu-complexity is a command-line tool for measuring the complexity of C source code. It helps developers examine code structure from a complexity perspective and identify the parts that are difficult to understand, maintain, and test, so they can be refactored or optimized in a targeted way. For teams that need to maintain C projects over the long term, engineers focused on code quality, and those conducting code reviews or technical debt assessments, this tool provides an objective reference. It is suitable for use alongside other analysis tools in the development process, giving code quality management a more concrete footing rather than relying solely on subjective judgment to decide where improvement is needed.
