Gem::DocManager is still present but is no longer required nor used by RubyGems.
Gem::RDoc replaces Gem::DocManager and uses a new hook to generate
documentation (Gem.done_installing). The functionality of Gem::RDoc will be
moving to a future version of rdoc.
The file rubygems/rdoc.rb will continue to exist to facilitate loading of the
proper code.
Additionally, --no-rdoc and --no-ri are now deprecated:
$ gem help install
[…]
Deprecated Options:
--[no-]rdoc Generate RDoc for installed gems
Use --document instead
--[no-]ri Generate ri data for installed gems.
Use --document instead
[…]
Replacing these is --document which accepts a comma separated list of
documentation types to generate. `gem install rake --doc=rdoc` will generate
only RDoc. `gem install rake --doc=rdoc,ri` is the default. `gem install rake
--no-doc` will generate no documentation.
Gem::RDoc uses a new done_installing hook to generate documentation which is
called with a Gem::DependencyInstaller instance and a list of
Gem::Specifications that have been installed.
Additionally the documentation types are available through the installer
instance passed to the done_installing hook:
Gem.done_installing do |installer, specs|
if installer.document.include? 'pretend' then
puts "Pretending to document: #{specs.map { |spec| spec.full_name }}"
end
end
