Automatic code quality tool for Ruby? [closed]

Solutons:


I’ve recently started looking for something like this for Ruby. What I’ve run across so far:

  • Saikuro
  • Roodi
  • Flog

These might be places to start. Unfortunately I haven’t used any of the three enough yet to offer a good opinion.

Saikuro and Flog can be good for getting a basic idea of code complexity. You can also use a tool like rcov to look at your test coverage.
There is a plugin for Rails projects that combine all those metrics into a single rake task. It is called metric_fu.

Projects I’ve found and tested recently:

  • https://github.com/railsbp/rails_best_practices
    • Seems to work, and gives sensible warnings
  • https://github.com/simplabs/excellent
    • Works, but quite a few false positives
  • https://github.com/troessner/reek
    • I disagree with most of the warnings from this tool, but it works
  • http://www.cs.umd.edu/projects/PL/druby/
    • This requires ocaml; I haven’t tried it, but it looks like it might be good
  • http://roodi.rubyforge.org/
    • does not appear to be Ruby 1.9 compatible
  • https://github.com/gdb/ruby-static-checker
    • Is broken for me, and only catches name errors, so unit tests should cover that.
  • https://github.com/michaeledgar/laser
    • Doesn’t compile for me
