     = Rake -- Ruby Make

     This is the main file for the Rake application.  Normally it is referenced
     as a library via a require statement, but it can be distributed
     independently as an application.
FileList | = | Rake::FileList |  | Alias FileList to be available at the top level.

### Public Instance methods

desc(description)

Describe the next rake task.

Example:

      desc "Run the Unit Tests"
      task :test => [:build]
        runtests
      end

[Source]

         # File lib/rake.rb, line 843
    843: def desc(description)
    844:   Rake.application.last_description = description
    845: end

directory(dir)

Declare a set of files tasks to create the given directories on demand.

Example:

      directory "testdata/doc"

[Source]

         # File lib/rake.rb, line 790
    790: def directory(dir)
    791:   Rake.each_dir_parent(dir) do |d|
    792:     file_create d do |t|
    793:       mkdir_p t.name if ! File.exist?(t.name)
    794:     end
    795:   end
    796: end

file(args, &block)

Declare a file task.

Example:

      file "config.cfg" => ["config.template"] do
        open("config.cfg", "w") do |outfile|
          open("config.template") do |infile|
            while line = infile.gets
              outfile.puts line
            end
          end
        end
     end

[Source]

         # File lib/rake.rb, line 775
    775: def file(args, &block)
    776:   Rake::FileTask.define_task(args, &block)
    777: end

file_create(args, &block)

Declare a file creation task. (Mainly used for the directory command).

[Source]

         # File lib/rake.rb, line 781
    781: def file_create(args, &block)
    782:   Rake::FileCreationTask.define_task(args, &block)
    783: end

import(*fns)

Import the partial Rakefiles `fn`. Imported files are loaded after the current file is completely loaded. This allows the import statement to appear anywhere in the importing file, and yet allowing the imported files to depend on objects defined in the importing file.

A common use of the import statement is to include files containing dependency declarations.

See also the —rakelibdir command line option.

Example:

      import ".depend", "my_rules"

[Source]

         # File lib/rake.rb, line 860
    860: def import(*fns)
    861:   fns.each do |fn|
    862:     Rake.application.add_import(fn)
    863:   end
    864: end

multitask(args, &block)

Declare a task that performs its prerequisites in parallel. Multitasks does not guarantee that its prerequisites will execute in any given order (which is obvious when you think about it)

Example:

      multitask :deploy => [:deploy_gem, :deploy_rdoc]

[Source]

         # File lib/rake.rb, line 805
    805: def multitask(args, &block)
    806:   Rake::MultiTask.define_task(args, &block)
    807: end

namespace(name=nil, &block)

Create a new rake namespace and use it for evaluating the given block. Returns a NameSpace object that can be used to lookup tasks defined in the namespace.

E.g.

      ns = namespace "nested" do
        task :run
      end
      task_run = ns[:run] # find :run in the given namespace.

[Source]

         # File lib/rake.rb, line 820
    820: def namespace(name=nil, &block)
    821:   Rake.application.in_namespace(name, &block)
    822: end

rule(*args, &block)

Declare a rule for auto-tasks.

Example:

     rule '.o' => '.c' do |t|
       sh %{cc -o #{t.name} #{t.source}}
     end

[Source]

         # File lib/rake.rb, line 831
    831: def rule(*args, &block)
    832:   Rake::Task.create_rule(*args, &block)
    833: end

task(*args, &block)

Declare a basic task.

Example:

      task :clobber => [:clean] do
        rm_rf "html"
      end

[Source]

         # File lib/rake.rb, line 757
    757: def task(*args, &block)
    758:   Rake::Task.define_task(*args, &block)
    759: end
