# Gem::ConfigFile RubyGems options and gem command options from gemrc.
|
|
#
|
|
# gemrc is a YAML file that uses strings to match gem command arguments and
|
|
# symbols to match RubyGems options.
|
|
#
|
|
# Gem command arguments use a String key that matches the command name and
|
|
# allow you to specify default arguments:
|
|
#
|
|
# install: --no-rdoc --no-ri
|
|
# update: --no-rdoc --no-ri
|
|
#
|
|
# You can use <tt>gem:</tt> to set default arguments for all commands.
|
|
#
|
|
# RubyGems options use symbol keys. Valid options are:
|
|
#
|
|
# +:backtrace+:: See #backtrace
|
|
# +:sources+:: Sets Gem::sources
|
|
# +:verbose+:: See #verbose
|
|
#
|
|
# gemrc files may exist in various locations and are read and merged in
|
|
# the following order:
|
|
#
|
|
# - system wide (/etc/gemrc)
|
|
# - per user (~/.gemrc)
|
|
# - per environment (gemrc files listed in the GEMRC environment variable)
