[](task_name, scopes=nil)

Find a matching task for task_name.

  task_name = task_name.to_s

    synthesize_file_task(task_name) or
    fail "Don't know how to build task '#{task_name}'"
end
clear()

Clear all tasks in this application.

  pattern, _, deps = resolve_args(args)
  pattern = Regexp.new(Regexp.quote(pattern) + '$') if String === pattern
  @rules << [pattern, deps, block]
end
current_scope()

Return the list of scope names currently active in the task manager.

  @scope.dup
end
define_task(task_class, *args, &block)

# File lib/rake/task_manager.rb, line 23
def define_task(task_class, *args, &block)
  task_name, arg_names, deps = resolve_args(args)
  task_name = task_class.scope_name(@scope, task_name)
  deps = [deps] unless deps.respond_to?(:to_ary)
  deps = deps.collect {|d| d.to_s }
  task = intern(task_class, task_name)

  if Rake::TaskManager.record_task_metadata
    add_location(task)
    task.add_description(get_description(task))
  end
  task.enhance(deps, &block)
end
enhance_with_matching_rule(task_name, level=0)

If a rule can be found that matches the task name, enhance the task with the prerequisites and actions from the rule. Set the source attribute of the task appropriately for the rule. Return the enhanced task or nil of no rule was found.

Source: show | on GitHub 

# File lib/rake/task_manager.rb, line 127
def enhance_with_matching_rule(task_name, level=0)
  fail Rake::RuleRecursionOverflowError,
    "Rule Recursion Too Deep" if level >= 16
  @rules.each do |pattern, extensions, block|
    if pattern.match(task_name)
      task = attempt_rule(task_name, extensions, block, level)
      return task if task
    end
  end
  nil
rescue Rake::RuleRecursionOverflowError => ex
  ex.add_target(task_name)
  fail ex
end
in_namespace(name)

Evaluate the block in a nested namespace named name. Create an anonymous namespace if name is nil.

Source: show | on GitHub 

# File lib/rake/task_manager.rb, line 203
def in_namespace(name)
  name ||= generate_name
  @scope.push(name)
  ns = NameSpace.new(self, @scope)
  yield(ns)
  ns
ensure
  @scope.pop
end
intern(task_class, task_name)

Lookup a task. Return an existing task if found, otherwise create a task of the current type.

Source: show | on GitHub 

# File lib/rake/task_manager.rb, line 39
def intern(task_class, task_name)
  @tasks[task_name.to_s] ||= task_class.new(task_name, self)
end
lookup(task_name, initial_scope=nil)

Lookup a task, using scope and the scope hints in the task name. This method performs straight lookups without trying to synthesize file tasks or rules. Special scope names (e.g. '^') are recognized. If no scope argument is supplied, use the current scope. Return nil if the task cannot be found.

Source: show | on GitHub 

# File lib/rake/task_manager.rb, line 167
def lookup(task_name, initial_scope=nil)
  initial_scope ||= @scope
  task_name = task_name.to_s
  if task_name =~ /^rake:/
    scopes = []
    task_name = task_name.sub(/^rake:/, '')
  elsif task_name =~ /^(\^+)/
    scopes = initial_scope[0, initial_scope.size - $1.size]
    task_name = task_name.sub(/^(\^+)/, '')
  else
    scopes = initial_scope
  end
  lookup_in_scope(task_name, scopes)
end
resolve_args(args)

Resolve the arguments for a task/rule. Returns a triplet of [task_name, arg_name_list, prerequisites].

Source: show | on GitHub 

# File lib/rake/task_manager.rb, line 59
def resolve_args(args)
  if args.last.is_a?(Hash)
    deps = args.pop
    resolve_args_with_dependencies(args, deps)
  else
    resolve_args_without_dependencies(args)
  end
end
synthesize_file_task(task_name)

Source: show | on GitHub 

# File lib/rake/task_manager.rb, line 52
def synthesize_file_task(task_name)
  return nil unless File.exist?(task_name)
  define_task(Rake::FileTask, task_name)
end
tasks()

List of all defined tasks in this application.

Source: show | on GitHub 

# File lib/rake/task_manager.rb, line 143
def tasks
  @tasks.values.sort_by { |t| t.name }
end
tasks_in_scope(scope)

List of all the tasks defined in the given scope (and its sub-scopes).

Source: show | on GitHub 

# File lib/rake/task_manager.rb, line 149
def tasks_in_scope(scope)
  prefix = scope.join(":")
  tasks.select { |t|
    /^#{prefix}:/ =~ t.name
  }
