# 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
|
|
#
|
|
# == Usage

# gem_server = Gem::Server.new Gem.dir, 8089, false

# 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 http://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:
|
|
# 1. first try to find the gems and documentation folders which name
|
|
# starts with the search term
|
|
# 2. search for entries, that *contain* the search term
|
|
# 3. 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
|
|
#
|
|
# 1. install Ruby sources
|
|
# cd /usr/src
|
|
# sudo apt-get source ruby
|
|
#
|
|
# 2. 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
