Question

What would be a reasonable way to calculate the cyclomatic complexity of a Clojure function? It's easy to count decision points based on functions like 'if' and 'cond', but it starts to get tricky with macros. Anyone has tried this for Clojure or maybe another functional language?

Was it helpful?

Solution

Macros are an abstraction and should not contributed to the CC calculation, any more than a function call would.

That said, I don't think that CC is particularly interesting for Clojure. I would be more interested in something that measured overuse of mutability.
