I'm searching for code analysing tools for Ruby . I know some tools
for Java and DotNet but i can't seem to find much for Ruby.
Things im interested in are metrics like coupling (fan-in, fan-out),
complexity (McCabe), inheritance nesting levels etc.

The only tools I found so far are saikuro(only mccabe) and kwala
(seems like a frontend for saikuro)

If you know of any other tools please let me know,
