Rake main application object. When invoking rake
from the
command line, a Rake::Application object is
created and run.
Initialize a Rake::Application object.
# File rake/application.rb, line 46 def initialize super @name = 'rake' @rakefiles = DEFAULT_RAKEFILES.dup @rakefile = nil @pending_imports = [] @imported = [] @loaders = {} @default_loader = Rake::DefaultLoader.new @original_dir = Dir.pwd @top_level_tasks = [] add_loader('rb', DefaultLoader.new) add_loader('rf', DefaultLoader.new) add_loader('rake', DefaultLoader.new) @tty_output = STDOUT.tty? @terminal_columns = ENV['RAKE_COLUMNS'].to_i end
Add a loader to handle imported files ending in the extension
ext
.
# File rake/application.rb, line 129 def add_loader(ext, loader) ext = ".#{ext}" unless ext =~ /^\./ @loaders[ext] = loader end
Initialize the command line parameters and app name.
# File rake/application.rb, line 83 def init(app_name='rake') standard_exception_handling do @name = app_name args = handle_options collect_command_line_tasks(args) end end
Find the rakefile and then load it and any pending imports.
# File rake/application.rb, line 92 def load_rakefile standard_exception_handling do raw_load_rakefile end end
Application options from the command line
# File rake/application.rb, line 135 def options @options ||= OpenStruct.new end
Run the Rake application. The run method performs the following three steps:
Initialize the command line options (init
).
Define the tasks (load_rakefile
).
Run the top level tasks (top_level
).
If you wish to build a custom rake command, you should call
init
on your application. Then define any tasks. Finally,
call top_level
to run your top level tasks.
# File rake/application.rb, line 74 def run standard_exception_handling do init load_rakefile top_level end end
Run the given block with the thread startup and shutdown.
# File rake/application.rb, line 112 def run_with_threads thread_pool.gather_history if options.job_stats == :history yield thread_pool.join if options.job_stats stats = thread_pool.statistics puts "Maximum active threads: #{stats[:max_active_threads]} + main" puts "Total threads in play: #{stats[:total_threads_in_play]} + main" end ThreadHistoryDisplay.new(thread_pool.history).show if options.job_stats == :history end
Run the top level tasks of a Rake application.
# File rake/application.rb, line 99 def top_level run_with_threads do if options.show_tasks display_tasks_and_comments elsif options.show_prereqs display_prerequisites else top_level_tasks.each { |task_name| invoke_task(task_name) } end end end
