Just want to join the chorus of thank you. This is perfect. I found a
blog entry (http://asplake.blogspot.com/2006/01/revert-that-rakefile.html)
and worked it over a little into the file below which I put in
lib/tasks/rcov.rake in a rails project. It works great.

Thanks

require ''rake/clean''

RBINDIR = Config::CONFIG[''bindir'']
RBIN = "#{RBINDIR}/rcov"
if File.exists?(RBIN)

  # output goes to subdirectories of this one
  RCOV_OUT = "coverage"

  # "rake clobber" to remove output directory (along with other
generated stuff)
  CLOBBER.include(RCOV_OUT)

  # don''t report coverage on these files
  RCOV_EXCLUDE = %w(boot.rb environment.rb vendor/rails
test/functional test/unit).join('','')

  # RCOV command, run as though from the commandline.  Amend as
required or perhaps move to config/environment.rb?
  RCOV = "#{RBINDIR}/ruby #{RBIN} --exclude #{RCOV_EXCLUDE} --output
#{RCOV_OUT}"

  desc "generate a coverage report for unit and functional tests
together in #{RCOV_OUT}/index.html"
  task :rcov do
    rm_rf RCOV_OUT
    sh "#{RCOV} test/unit/*.rb test/functional/*.rb"
  end

  namespace :rcov do
    desc "generate a unit test coverage report in
#{RCOV_OUT}/index.html"
    task :units do
      sh "#{RCOV} test/unit/*.rb"
    end

    desc "generate a functional test coverage report in
#{RCOV_OUT}/index.html"
    task :coverage_functional do
      sh "#{RCOV} test/functional/*.rb"
    end
  end

end

Wouldn''t it be better if you used rake''s "ruby"
method instead of "sh"
to call another Ruby script?
