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

:sources

Sets Gem::sources

:verbose

See #verbose

:concurrent_downloads

See #concurrent_downloads

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)

#initialize(args) ⇒ 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.

– TODO: parse options upstream, pass in options directly
