RDocTask

RDoc::Task creates the following rake tasks to generate and clean up RDoc output:

rdoc

Main task for this RDoc task.

clobber_rdoc

Delete all the rdoc files. This target is automatically added to the main clobber target.

rerdoc

Rebuild the rdoc files from scratch, even if they are not out of date.

Simple Example:

require 'rdoc/task'

RDoc::Task.new do |rdoc|
  rdoc.main = "README.rdoc"
  rdoc.rdoc_files.include("README.rdoc", "lib   /*.rb")
end

The rdoc object passed to the block is an RDoc::Task object. See the attributes list for the RDoc::Task class for available customization options.

Specifying different task names

You may wish to give the task a different name, such as if you are generating two sets of documentation. For instance, if you want to have a development set of documentation including private methods:

require 'rdoc/task'

RDoc::Task.new :rdoc_dev do |rdoc|
  rdoc.main = "README.doc"
  rdoc.rdoc_files.include("README.rdoc", "lib/   *.rb")
  rdoc.options << "--all"
end

The tasks would then be named :rdoc_dev, :clobber_rdoc_dev, and :rerdoc_dev.

If you wish to have completely different task names, then pass a Hash as first argument. With the :rdoc, :clobber_rdoc and :rerdoc options, you can customize the task names to your liking.

For example:

require 'rdoc/task'

RDoc::Task.new(:rdoc => "rdoc", :clobber_rdoc => "rdoc:clean",
               :rerdoc => "rdoc:force")

This will create the tasks :rdoc, :rdoc:clean and :rdoc:force.

Public Class Methods

new(name = :rdoc) click to toggle source

Create an RDoc task with the given name. See the RDoc::Task class overview for documentation.

 
               # File rdoc/task.rb, line 155
def initialize name = :rdoc # :yield: self
  defaults

  check_names name

  @name = name

  yield self if block_given?

  define
end
            

Public Instance Methods

before_running_rdoc(&block) click to toggle source

The block passed to this method will be called just before running the RDoc generator. It is allowed to modify RDoc::Task attributes inside the block.

 
               # File rdoc/task.rb, line 273
def before_running_rdoc(&block)
  @before_running_rdoc = block
end
            
check_names(names) click to toggle source

Ensures that names only includes names for the :rdoc, :clobber_rdoc and :rerdoc. If other names are given an ArgumentError is raised.

 
               # File rdoc/task.rb, line 171
def check_names names
  return unless Hash === names

  invalid_options =
    names.keys.map { |k| k.to_sym } - [:rdoc, :clobber_rdoc, :rerdoc]

  unless invalid_options.empty? then
    raise ArgumentError, "invalid options: #{invalid_options.join ', '}"
  end
end
            
clobber_task_description() click to toggle source

Task description for the clobber rdoc task or its renamed equivalent

 
               # File rdoc/task.rb, line 185
def clobber_task_description
  "Remove RDoc HTML files"
end
            
defaults() click to toggle source

Sets default task values

 
               # File rdoc/task.rb, line 192
def defaults

  @rdoc_files = Rake::FileList.new
  @rdoc_dir = 'html'
  @main = nil
  @title = nil
  @template = nil
  @generator = nil
  @options = []
end
            
define() click to toggle source

Create the tasks defined by this task lib.

def define
  desc rdoc_task_description
  task rdoc_task_name

  desc rerdoc_task_description

  desc clobber_task_description
  task clobber_task_name do
    rm_r @rdoc_dir rescue nil
  end

  task :clobber => [clobber_task_name]

  directory @rdoc_dir

  rdoc_target_deps = [
    @rdoc_files,
    Rake.application.rakefile
  ].flatten.compact

  task rdoc_task_name => [rdoc_target]
  file rdoc_target => rdoc_target_deps do
    @before_running_rdoc.call if @before_running_rdoc
    args = option_list + @rdoc_files

    $stderr.puts "rdoc #{args.join ' '}" if Rake.application.options.trace
    RDoc::RDoc.new.document args
  end

  self
end
            
option_list() click to toggle source

List of options that will be supplied to RDoc

 
               # File rdoc/task.rb, line 257
