class RDoc::Task

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Rebuild the rdoc files from scratch, even if they are not out of date.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) { |self| ... } click to toggle source

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

# File lib/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 lib/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 lib/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
