# File 'lib/rake/file_list.rb', line 418



def each_dir_parent(dir)    # :nodoc:
  old_length = nil
  while dir != "." && dir.length != old_length
    yield(dir)

    dir = File.dirname(dir)
  end
end


  








  

    .from_pathname(path)  
  

  

    This method is for internal use only.
  



  

    

Convert Pathname and Pathname-like objects to strings; leave everything else alone


  



  [ GitHub ]


  

  


# File 'lib/rake/file_list.rb', line 429



def from_pathname(path)    # :nodoc:
  path = path.to_path if path.respond_to?(:to_path)
  path = path.to_str if path.respond_to?(:to_str)
  path
end


  








  

    .load_rakefile(path)  
  



  

    

Load a rakefile.

    .suggested_thread_count  
  

  

    This method is for internal use only.
  

  [ GitHub ]

  @cpu_count + 4
end


  








  

    .with_application(block_application = Rake::Application.new)  
  



  

    

Make block_application the default rake application inside a block so you can load rakefiles into a different application.



This is useful when you want to run rake tasks inside a library without running rake in a sub-shell.



Example:



Dir.chdir 'other/directory'

other_rake = Rake.with_application do |rake|
  rake.load_rakefile
end

puts other_rake.tasks

# File 'lib/rake/rake_module.rb', line 54



def with_application(block_application = Rake::Application.new)
  orig_application = Rake.application

  Rake.application = block_application

  yield block_application

  block_application
ensure
  Rake.application = orig_application
