Overview

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rerdoc: Rebuild the rdoc files from scratch, even if they are not out of date.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 Task object. See the attributes list for the 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.
