This gem generates a treemap
showing the complexity of ruby code on which it is run. It uses
Saikuro under the covers to analyze ruby
code complexity.

The size of blocks in the treemap is representative of the size of the
code element represented by that block. The color of the block indicates
complexity of that particular code element. Green is good, red is bad,
blue is somewhere in between.

Small evenly distributed blocks which are green in color is indicative of
good code.

of the CCN for the popular rake tool.

$ [sudo] gem install saikuro_treemap

In your Rakefile, add the following:

require 'saikuro_treemap'

namespace :metrics do
  desc 'generate ccn treemap'
  task :ccn_treemap do
    SaikuroTreemap.generate_treemap :code_dirs => ['lib']
    `open reports/saikuro_treemap.html`
  end
end

$ rake metrics:ccn_treemap

This would generate the treemap report in “reports/saikuro_treemap.html”.
