module RDoc

RDoc produces documentation for Ruby source files by parsing the source and extracting the definition for classes, modules, methods, includes and requires. It associates these with optional documentation contained in an immediately preceding comment block then renders the result using an output formatter.

For a simple introduction to writing or generating documentation using RDoc see the README.

Roadmap¶ ↑

If you think you found a bug in RDoc see Bugs at CONTRIBUTING

If you want to use RDoc to create documentation for your Ruby source files, see RDoc::Markup and refer to rdoc --help for command line usage.

If you want to set the default markup format see Markup Formats at RDoc::Markup

If you want to store rdoc configuration in your gem (such as the default markup format) see Saved Options at RDoc::Options

If you want to write documentation for Ruby files see RDoc::Parser::Ruby

If you want to write documentation for extensions written in C see RDoc::Parser::C

If you want to generate documentation using rake see RDoc::Task.

If you want to drive RDoc programmatically, see RDoc::RDoc.

If you want to use the library to format text blocks into HTML or other formats, look at RDoc::Markup.

If you want to make an RDoc plugin such as a generator or directive handler see RDoc::RDoc.

If you want to write your own output generator see RDoc::Generator.

Credits¶ ↑

RDoc is currently being maintained by Eric Hodel <drbrain@segment7.net>.

Dave Thomas <dave@pragmaticprogrammer.com> is the original author of RDoc.

The Ruby parser in rdoc/parse.rb is based heavily on the outstanding work of Keiju ISHITSUKA of Nippon Rational Inc, who produced the Ruby parser for irb and the rtags package.

This class is referenced by RubyGems to create documents. All implementations are moved to the above RubyGemsHook.

This class does nothing when this RDoc is installed as a normal gem or a bundled gem.

This class does generate/remove documents for compatibility when this RDoc is installed as a default gem.

We can remove this when all maintained RubyGems remove ‘rubygems/rdoc.rb`.

Constants

ATTR_MODIFIERS: RDoc modifiers for attributes
CLASS_MODIFIERS: RDoc modifiers for classes
CONSTANT_MODIFIERS: RDoc modifiers for constants
DOT_DOC_FILENAME: Name of the dotfile that contains the description of files to be processed in the current directory
GENERAL_MODIFIERS: General RDoc modifiers
KNOWN_CLASSES: Ruby’s built-in classes, modules and exceptions
METHOD_MODIFIERS: RDoc modifiers for methods
VERSION: RDoc version you are using
VISIBILITIES: Method visibilities

Public Class Methods

home ()

Source

# File lib/rdoc.rb, line 132
def self.home
  rdoc_dir = begin
              File.expand_path('~/.rdoc')
            rescue ArgumentError
            end

  if File.directory?(rdoc_dir)
    rdoc_dir
  else
    require 'fileutils'
    begin
      # XDG
      xdg_data_home = ENV["XDG_DATA_HOME"] || File.join(File.expand_path("~"), '.local', 'share')
      unless File.exist?(xdg_data_home)
        FileUtils.mkdir_p xdg_data_home
      end
      File.join xdg_data_home, "rdoc"
    rescue Errno::EACCES
    end
  end
end

Searches and returns the directory for settings.

$HOME/.rdoc directory, if it exists.
The rdoc directory under the path specified by the XDG_DATA_HOME environment variable, if it is set.
$HOME/.local/share/rdoc directory.

Other than the home directory, the containing directory will be created automatically.

load_yaml ()

Source

# File lib/rdoc.rb, line 105
def self.load_yaml
  begin
    gem 'psych'
  rescue NameError => e # --disable-gems
    raise unless e.name == :gem
  rescue Gem::LoadError
  end

  begin
    require 'psych'
  rescue ::LoadError
  ensure
    require 'yaml'
  end
end

Loads the best available YAML library.
