Public Class Methods

generation_hook(installer, specs) click to toggle source

Post installs hook that generates documentation for each specification in specs

 
               # File rdoc/rubygems_hook.rb, line 47
def self.generation_hook installer, specs
  types     = installer.document

  generate_rdoc = types.include? 'rdoc'
  generate_ri   = types.include? 'ri'

  specs.each do |spec|
    new(spec, generate_rdoc, generate_ri).generate
  end
end
            
load_rdoc() click to toggle source

Loads the RDoc generator

 
               # File rdoc/rubygems_hook.rb, line 61
def self.load_rdoc
  return if @rdoc_version

  require 'rdoc/rdoc'

  @rdoc_version = Gem::Version.new ::RDoc::VERSION
end
            
new(spec, generate_rdoc = true, generate_ri = true) click to toggle source

Creates a new documentation generator for spec. RDoc and ri data generation can be disabled through generate_rdoc and generate_ri respectively.

 
               # File rdoc/rubygems_hook.rb, line 74
def initialize spec, generate_rdoc = true, generate_ri = true
  @doc_dir   = spec.doc_dir
  @file_info = nil
  @force     = false
  @rdoc      = nil
  @spec      = spec

  @generate_rdoc = generate_rdoc
  @generate_ri   = generate_ri

  @rdoc_dir = spec.doc_dir 'rdoc'
  @ri_dir   = spec.doc_dir 'ri'
end

  options.finish

  @rdoc.options = options
  @rdoc.generator = options.generator.new options

  say "Installing #{generator} documentation for #{@spec.full_name}"

  FileUtils.mkdir_p options.op_dir

  Dir.chdir options.op_dir do
    begin
      @rdoc.class.current = @rdoc
