# == RubyGems Plugins
|
|
|
|
#
|
|
|
|
# As of RubyGems 1.3.2, RubyGems will load plugins installed in gems or
|
2010-02-21 21:52:35 -05:00
|
|
|
# $LOAD_PATH. Plugins must be named 'rubygems_plugin' (.rb, .so, etc) and
|
|
|
|
# placed at the root of your gem's #require_path. Plugins are discovered via
|
2009-06-09 17:38:59 -04:00
|
|
|
# Gem::find_files then loaded. Take care when implementing a plugin as your
|
|
|
|
# plugin file may be loaded multiple times if multiple versions of your gem
|
|
|
|
# are installed.
|
|
|
|
#
|
|
|
|
# For an example plugin, see the graph gem which adds a `gem graph` command.
|
|
|
|
#
|
|
|
|
# == RubyGems Defaults, Packaging
|
|
|
|
#
|
|
|
|
# RubyGems defaults are stored in rubygems/defaults.rb. If you're packaging
|
|
|
|
# RubyGems or implementing Ruby you can change RubyGems' defaults.
|
|
|
|
#
|
|
|
|
# For RubyGems packagers, provide lib/rubygems/operating_system.rb and
|
|
|
|
# override any defaults from lib/rubygems/defaults.rb.
|
|
|
|
#
|
|
|
|
# For Ruby implementers, provide lib/rubygems/#{RUBY_ENGINE}.rb and override
|
|
|
|
# any defaults from lib/rubygems/defaults.rb.
|
|
|
|
#
|
|
|
|
# If you need RubyGems to perform extra work on install or uninstall, your
|
|
|
|
# defaults override file can set pre and post install and uninstall hooks.
|
|
|
|
# See Gem::pre_install, Gem::pre_uninstall, Gem::post_install,
|
|
|
|
# Gem::post_uninstall.
