module Rake::DSL
Private Instance Methods
Describe the next rake task.
Example:
desc "Run the Unit Tests" task :test => [:build] runtests end
# File lib/rake/dsl_definition.rb, line 117 def desc(description) Rake.application.last_description = description end
Declare a set of files tasks to create the given directories on demand.
Example:
directory "testdata/doc"
# File lib/rake/dsl_definition.rb, line 58 def directory(dir) Rake.each_dir_parent(dir) do |d| file_create d do |t| mkdir_p t.name if ! File.exist?(t.name) end end end
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
# File lib/rake/dsl_definition.rb, line 42 def file(*args, &block) Rake::FileTask.define_task(*args, &block) end
Declare a file creation task. (Mainly used for the directory command).
# File lib/rake/dsl_definition.rb, line 48 def file_create(args, &block) Rake::FileCreationTask.define_task(args, &block) end
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"
# File lib/rake/dsl_definition.rb, line 135 def import(*fns) fns.each do |fn| Rake.application.add_import(fn) end end
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]
# File lib/rake/dsl_definition.rb, line 74 def multitask(args, &block) Rake::MultiTask.define_task(args, &block) end
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.
# File lib/rake/dsl_definition.rb, line 89 def namespace(name=nil, &block) name = name.to_s if name.kind_of?(Symbol) name = name.to_str if name.respond_to?(:to_str) unless name.kind_of?(String) || name.nil? raise ArgumentError, "Expected a String or Symbol for a namespace name" end Rake.application.in_namespace(name, &block) end
Declare a rule for auto-tasks.
Example:
rule '.o' => '.c' do |t| sh %Q{cc -o #{t.name} #{t.source}} end
# File lib/rake/dsl_definition.rb, line 105 def rule(*args, &block) Rake::Task.create_rule(*args, &block) end
Declare a basic task.
Example:
task :clobber => [:clean] do rm_rf "html" end
# File lib/rake/dsl_definition.rb, line 24 def task(*args, &block) Rake::Task.define_task(*args, &block) end
