Gem::Server and allows users to serve gems for consumption by `gem --remote-install`.
gem_server starts an HTTP server on the given port and serves the following:
“/” - Browsing of gem spec files for installed gems
“/specs.#{Gem.marshal_version}.gz” - specs name/version/platform index
“/latest_specs.#{Gem.marshal_version}.gz” - latest specs name/version/platform index
“/quick/” - Individual gemspecs
“/gems” - Direct access to download the installable gems
“/rdoc?q=” - Search for installed rdoc documentation
legacy indexes:
“/Marshal.#{Gem.marshal_version}” - Full SourceIndex dump of metadata for installed gems
gem_server = Gem::Server.new Gem.dir, 8089, false gem_server.run
CSS is copy & paste from rdoc-style.css, RDoc V1.0.1 - 20041108
Only the first directory in gem_dirs is used for serving gems

Can be used for quick navigation to the rdoc documentation. You can then define a search shortcut for your browser. E.g. in Firefox connect ‘shortcut:rdoc’ to localhost:8808/rdoc?q=%s template. Then you can directly open the ActionPack documentation by typing ‘rdoc actionp’. If there are multiple hits for the search term, they are presented as a list with links.
Search algorithm aims for an intuitive search:
first try to find the gems and documentation folders which name starts with the search term
search for entries, that contain the search term
show all the gems
If there is only one search hit, user is immediately redirected to the documentation for the particular gem, otherwise a list with results is shown.
Note: please adjust paths accordingly use for example ‘locate yaml.rb’ and ‘gem environment’ to identify directories, that are specific for your local installation
install ruby sources
cd /usr/src sudo apt-get source ruby
generate documentation
rdoc -o /usr/lib/ruby/gems/1.8/doc/core/rdoc \ /usr/lib/ruby/1.8 ruby1.8-1.8.7.72
By typing ‘rdoc core’ you can now access the core documentation

Returns true and prepares http response, if rdoc for the requested gem name pattern was found.
The search is based on the file system content, not on the gems metadata. This allows additional documentation folders like ‘core’ for the ruby core documentation - just put it underneath the main doc folder.
