A rake task by .rake file

Ruby
#1

I have the following Rakefile in a Ruby 1.9.3 project:

require ‘rake/testtask’
require ‘json’

Rake::TestTask.new do |t|
t.pattern = “spec/**/*_spec.rb”
t.verbose = true
end

task :default => :test

namespace :omglol do
namespace :file_a do
task :foo do
# do some stuff
end
end

namespace :file_b do
  task :bar do
    # do some stuff
  end
end

end

As you can see, the first part of this file allow to run tests, just
using rake command. And the second part contains some tasks.

Actually, I have a lot of tasks inside omglol:file_a and omglol:file_b
namespaces. That’s why I would like to move each of them inside a file,
for instance tasks/omglol/file_a.rake and tasks/omglol/file_b.rake.

Is there a simple way to do so? Thanks.
