class RDoc::RDoc

This is the driver for generating RDoc output. It handles file parsing and generation of output.

To use this class to generate RDoc output via the API, the recommended way is:

rdoc = RDoc::RDoc.new
options = rdoc.load_options # returns an RDoc::Options instance
# set extra options
rdoc.document options

You can also generate output like the rdoc executable:

rdoc = RDoc::RDoc.new
rdoc.document argv

Where argv is an array of strings, each corresponding to an argument you'd give rdoc on the command line. See <tt>rdoc –help<tt> for details.

Constants

GENERATORS

This is the list of supported output generators

Attributes

generator[RW]

Generator instance used for creating output

last_modified[R]

Hash of files and their last modified times.

options[RW]

RDoc options

stats[R]

Accessor for statistics. Available after each call to #parse_files

store[R]

The current documentation store

Public Class Methods

add_generator(klass) click to toggle source

Add klass that can generate output after parsing

# File lib/rdoc/rdoc.rb, line 66
def self.add_generator(klass)
  name = klass.name.sub(/^RDoc::Generator::/, '').downcase
  GENERATORS[name] = klass
end
current() click to toggle source

Active RDoc::RDoc instance

# File lib/rdoc/rdoc.rb, line 74
def self.current
  @current
end
current=(rdoc) click to toggle source

Sets the active RDoc::RDoc instance

# File lib/rdoc/rdoc.rb, line 81
def self.current= rdoc
  @current = rdoc
end
new() click to toggle source

Creates a new RDoc::RDoc instance. Call document to parse files and generate documentation.

# File lib/rdoc/rdoc.rb, line 89
def initialize
  @current       = nil
  @generator     = nil
  @last_modified = {}
  @old_siginfo   = nil
  @options       = nil
  @stats         = nil
  @store         = nil
end

Public Instance Methods

document(options) click to toggle source

Generates documentation or a coverage report depending upon the settings in options.

options can be either an RDoc::Options instance or an array of strings equivalent to the strings that would be passed on the command line like %w[-q -o doc -t My\ Doc\ Title]. document will automatically call RDoc::Options#finish if an options instance was given.

For a list of options, see either RDoc::Options or rdoc --help.

By default, output will be stored in a directory called “doc” below the current directory, so make sure you're somewhere writable before invoking.

# File lib/rdoc/rdoc.rb, line 453

  self.store = RDoc::Store.new
