Printing measurements to stdout via Rake tasks

[jimmycuadra]

Is there a way to make the measurement Rake tasks output results to stdout instead of a file, just as the CLI does? It looks like Yardstick::Config#output is coerced into a Yardstick::ReportOutput, which in turn coerces its target to a Pathname. I'd like to be able to just set config.output to an IO object directly.

I managed to accomplish this via:

require 'yard'
require 'yaml'
require 'yardstick/rake/measurement'
require 'yardstick/rake/verify'

namespace :doc do
  yardstick_opts = YAML.load(File.read('.yardstick.yml'))
  yardstick_report = File.join('doc', 'coverage', 'report.txt')
  Yardstick::Rake::Measurement.new(:lint, yardstick_opts) do |measurement|
    measurement.output = yardstick_report
  end
  task :output_report do
    puts File.read(yardstick_report)
  end
  namespace :lint do
    Yardstick::Rake::Verify.new(:verify, yardstick_opts) do |verify|
      verify.threshold = 95
    end
  end
end

YARD::Rake::YardocTask.new(:doc) do |t|
  t.files         = ['lib/**/*.rb', 'spec/**/*_spec.rb']
  t.stats_options = ['--list-undoc']
end

Rake::Task[:'doc:lint'].enhance do
  Rake::Task[:'doc:output_report'].invoke
end

Rake::Task[:doc].enhance do
  Rake::Task[:'doc:lint'].invoke
  Rake::Task[:'doc:lint:verify'].invoke
end
