ZenProfiler provides a faster version of the standard library ruby profiler. It is otherwise pretty much the same as before. spyon provides a clean way to redefine a bottleneck method so you can account for and aggregate all the calls to it.

% ruby -Ilib bin/zenprofile misc/factorial.rb 50000

Total time = 2.390000

          total     self              self    total

Once you know that Integer#downto takes 50% of the entire run, you can use spy_on to find it. (See misc/factorial.rb for the actual code):

% SPY=1 ruby -Ilib misc/factorial.rb 50000
Spying on Integer#downto

Integer.downto

50000: total
50000: ./misc/factorial.rb:6:in `factorial' via 
       ./misc/factorial.rb:6:in `factorial'

ZenTest scans your target and unit-test code and writes your missing code based on simple naming rules, enabling XP at a much quicker pace. ZenTest only works with Ruby and Test::Unit. Nobody uses this tool anymore but it is the package namesake, so it stays.

unit_diff is a command-line filter to diff expected results from actual results and allow you to quickly see exactly what is wrong.

autotest is a continous testing facility meant to be used during development. As soon as you save a file, autotest will run the corresponding dependent tests.

multiruby runs anything you want on multiple versions of ruby. Great for compatibility checking! Use multiruby_setup to manage your installed versions.
