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.

Public Class Methods

home() click to toggle source

Seaches and returns the directory for settings.

  1. $HOME/.rdoc directory, if it exists.

  2. The rdoc directory under the path specified by the XDG_DATA_HOME environment variable, if it is set.

  3. $HOME/.local/share/rdoc directory.

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

# File rdoc.rb, line 134
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
load_yaml() click to toggle source

Loads the best available YAML library.

# File rdoc.rb, line 107
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
