def self.all(&block)
  result = []
  Dir.directories(Path.applications) do |dir|
    next if dir == 'default'
    if app = find(dir)
      block_given? ? yield(app) : result << app
    end
  end
  result
end

.current ⇒ Object

This method identifies the desired application and initializes it in to @@current. It is meant to be very robust, we expect the application to be any one of the first three arguments.

def self.current
  @@current ||= begin
    Applications.find(ARGV.first) || Applications.find(ARGV.second) || Applications.find(ARGV.third)
  end
end

.current! ⇒ Object

Forces a reload of the current application. This method is useful for functional tests.
