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rerdoc: Rebuild the rdoc files from scratch, even if they are not out of date.
rdoc:coverage: Print RDoc coverage report for all rdoc files.

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.rdoc"
  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, :rdoc:force, and :rdoc:coverage.

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 158
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 288
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 174
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
