RDoc::Task creates the following rake tasks to generate and clean up RDoc output:
- rdoc
-
Main task for this
RDoctask. - 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Rebuild the rdoc files from scratch, even if they are not out of date.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.
Name of the main, top level task. (default is :rdoc)
Comment markup format. rdoc, rd and tomdoc are supported. (default is ‘rdoc’)
Name of directory to receive the html output files. (default is “html”)
Name of file to be used as the main, top level file of the RDoc. (default is none)
Name of template to be used by rdoc. (defaults to rdoc’s default)
Name of format generator (<tt>–format<tt>) used by rdoc. (defaults to rdoc’s default)
List of files to be included in the rdoc generation. (default is [])
Additional list of options to be passed rdoc. (default is [])
Whether to run the rdoc process as an external shell (default is false)
# File tmp/rubies/ruby-2.5.9/lib/rdoc/task.rb, line 155
def initialize name = :rdoc # :yield: self

end
Create an RDoc task with the given name. See the RDoc::Task class overview for documentation.
# File tmp/rubies/ruby-2.5.9/lib/rdoc/task.rb, line 273
def before_running_rdoc(&block)
@before_running_rdoc = block
end
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 tmp/rubies/ruby-2.5.9/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
end
Ensures that names only includes names for the :rdoc, :clobber_rdoc and :rerdoc. If other names are given an ArgumentError is raised.
