# File 'lib/rubygems/commands/environment_command.rb', line 22 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 ~/.gemrc file for individual users and a /etc/gemrc for all users. A gemrc is a YAML file 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 gem_command: A string containing arguments for the specified gem command Example: :verbose: false install: --no-wrappers update: --no-wrappers 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 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 |
