require 'rubygems/command' class Gem::Commands::EnvironmentCommand < Gem::Command def initialize super 'environment', 'Display information about the RubyGems environment' end def arguments # :nodoc: args = <<-EOF packageversion display the package version gemdir display the path where gems are installed gempath display path used to search for gems version display the gem format version remotesources display the remote gem servers platform display the supported gem platforms <omitted> display everything EOF return args.gsub(/^\s+/, '') end def description # :nodoc: <<-EOF The RubyGems environment can be controlled through command line arguments, gemrc files, environment variables and built-in defaults. Command line argument defaults and some RubyGems defaults can be set in a ~/.gemrc file for individual users and a /etc/gemrc for all users. These files are YAML files with the following YAML keys: :sources: A YAML array of remote gem repositories to install gems from :verbose: Verbosity of the gem command. false, true, and :really are the levels :update_sources: Enable/disable automatic updating of repository metadata :backtrace: Print backtrace when RubyGems encounters an error :gempath: The paths in which to look for gems :disable_default_gem_server: Force specification of gem server host on push <gem_command>: A string containing arguments for the specified gem command Example: :verbose: false install: --no-wrappers update: --no-wrappers :disable_default_gem_server: true RubyGems' default local repository can be overridden with the GEM_PATH and GEM_HOME environment variables. GEM_HOME sets the default repository to install into. GEM_PATH allows multiple local repositories to be searched for gems. If you are behind a proxy server, RubyGems uses the HTTP_PROXY, HTTP_PROXY_USER and HTTP_PROXY_PASS environment variables to discover the proxy server. If you would like to push gems to a private gem server the RUBYGEMS_HOST environment variable can be set to the URI for that server. If you are packaging RubyGems all of RubyGems' defaults are in lib/rubygems/defaults.rb. You may override these in lib/rubygems/defaults/operating_system.rb EOF end def usage # :nodoc: "#{program_name} [arg]" end def execute out = '' arg = options[:args][0] case arg when /^packageversion/ then out << Gem::RubyGemsPackageVersion when /^version/ then out << Gem::VERSION when /^gemdir/, /^gemhome/, /^home/, /^GEM_HOME/ then out << Gem.dir when /^gempath/, /^path/, /^GEM_PATH/ then out << Gem.path.join(File::PATH_SEPARATOR) when /^remotesources/ then out << Gem.sources.to_a.join("\n") when /^platform/ then out << Gem.platforms.join(File::PATH_SEPARATOR) when nil then out = "RubyGems Environment:\n" out << " - RUBYGEMS VERSION: #{Gem::VERSION}\n" out << " - RUBY VERSION: #{RUBY_VERSION} (#{RUBY_RELEASE_DATE}" out << " patchlevel #{RUBY_PATCHLEVEL}" if defined?
