Overview
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 gem:
to set default arguments for all commands.
RubyGems options use symbol keys. Valid options are:
:backtrace
-
See #backtrace
:benchmark
-
See #benchmark
:sources
-
Sets Gem::sources
:verbose
-
See #verbose

Constructor Details
#initialize(arg_list) ⇒ ConfigFile
Create the config file object. args
is the list of arguments from the command line.
The following command line options are handled early here rather than later at the time most command options are processed.
--config-file
,--config-file==NAME
-
Obviously these need to be handled by the ConfigFile object to ensure we get the right config file.
--backtrace
-
Backtrace needs to be turned on early so that errors before normal option parsing can be properly handled.
--debug
-
Enable Ruby level debug messages. Handled early for the same reason as –backtrace.
