class Gem::ConfigFile

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

gemrc files may exist in various locations and are read and merged in the following order:

Constants

DEFAULT_BACKTRACE
DEFAULT_BULK_THRESHOLD
DEFAULT_UPDATE_SOURCES
DEFAULT_VERBOSITY
OPERATING_SYSTEM_DEFAULTS

For Ruby packagers to set configuration defaults. Set in rubygems/defaults/operating_system.rb

PLATFORM_DEFAULTS

For Ruby implementers to set configuration defaults. Set in rubygems/defaults/#{RUBY_ENGINE}.rb

SYSTEM_WIDE_CONFIG_FILE

Attributes

args[R]

List of arguments supplied to the config file object.

backtrace[W]

True if we print backtraces on errors.

bulk_threshold[RW]

Bulk threshold value. If the number of missing gems are above this threshold value, then a bulk download technique is used. (deprecated)

disable_default_gem_server[RW]

True if we want to force specification of gem server when pushing a gem

home[RW]

Where to install gems (deprecated)

path[RW]

Where to look for gems (deprecated)

ssl_ca_cert[RW]

Path name of directory or file of openssl CA certificate, used for remote https connection

ssl_client_cert[R]

Path name of directory or file of openssl client certificate, used for remote https connection with client authentication

ssl_verify_mode[R]

openssl verify mode value, used for remote https connection

update_sources[RW]

True if we want to update the SourceInfoCache every time, false otherwise

verbose[RW]

Verbose level of output:

  • false – No output

  • true – Normal output

  • :loud – Extra output

Public Class Methods

new(args) click to toggle source

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.

[](key) click to toggle source

Return the configuration information for key.

def [](key)
  @hash[key.to_s]
end
[]=(key, value) click to toggle source

Set configuration option key to value.

# File lib/rubygems/config_file.rb, line 470
def []=(key, value)
  @hash[key.to_s] = value
end
api_keys() click to toggle source

Hash of RubyGems.org and alternate API keys

  @api_keys
end
backtrace() click to toggle source

True if the backtrace option has been specified, or debug is on.

# File lib/rubygems/config_file.rb, line 351
def backtrace
  @backtrace or $DEBUG
end
check_credentials_permissions() click to toggle source

Checks the permissions of the credentials file. If they are not 0600 an error message is displayed and RubyGems aborts.

# File lib/rubygems/config_file.rb, line 244
  def check_credentials_permissions
    return if Gem.win_platform? # windows doesn't write 0600 as 0600
    return unless File.exist? credentials_path

    existing_permissions = File.stat(credentials_path).mode & 0777

    return if existing_permissions == 0600

    alert_error <<-ERROR
Your gem push credentials file located at:

\t#{credentials_path}

has file permissions of 0#{existing_permissions.to_s 8} but 0600 is required.

To fix this error run:

\tchmod 0600 #{credentials_path}

You should reset your credentials at:

\thttps://rubygems.org/profile/edit

if you believe they were disclosed to a third party.
