Used to raise parsing and loading errors
Raised by Resolver when a dependency requests a gem for which there is no spec.
The SourceList
represents the sources rubygems has been configured to use. A source may be created from an array of sources:
Gem::SourceList.from %w[https://rubygems.example https://internal.example]
Or by adding them:
sources = Gem::SourceList.new sources << 'https://rubygems.example'
The most common way to get a SourceList
is Gem.sources
.
The Specification
class contains the information for a gem. Typically defined in a .gemspec file or a Rakefile, and looks like this:
Gem::Specification.new do |s| s.name = 'example' s.version = '0.1.0' s.licenses = ['MIT'] s.summary = "This is an example!" s.description = "Much longer explanation of the example!" s.authors = ["Ruby Coder"] s.email = 'rubycoder@example.com' s.files = ["lib/example.rb"] s.homepage = 'https://rubygems.org/gems/example' s.metadata = { "source_code_uri" => "https://github.com/example/example" } end
Starting in RubyGems 2.0, a Specification
can hold arbitrary metadata. See metadata
for restrictions on the format and size of metadata items you may add to a specification.
Process::Status
encapsulates the information on the status of a running or terminated system process. The built-in variable $?
is either nil
or a Process::Status
object.
fork { exit 99 } #=> 26557 Process.wait #=> 26557 $?.class #=> Process::Status $?.to_i #=> 25344 $? >> 8 #=> 99 $?.stopped? #=> false $?.exited? #=> true $?.exitstatus #=> 99
Posix systems record information on processes using a 16-bit integer. The lower bits record the process status (stopped, exited, signaled) and the upper bits possibly contain additional information (for example the program’s return code in the case of exited processes). Pre Ruby 1.8, these bits were exposed directly to the Ruby program. Ruby now encapsulates these in a Process::Status
object. To maximize compatibility, however, these objects retain a bit-oriented interface. In the descriptions that follow, when we talk about the integer value of stat, we’re referring to this 16 bit value.
Used to construct C classes (CUnion
, CStruct
, etc)
Fiddle::Importer#struct
and Fiddle::Importer#union
wrap this functionality in an easy-to-use manner.
Provides classes and methods to request, create and validate RFC3161-compliant timestamps. Request
may be used to either create requests from scratch or to parse existing requests that again can be used to request timestamps from a timestamp server, e.g. via the net/http. The resulting timestamp response may be parsed using Response
.
Please note that Response
is read-only and immutable. To create a Response
, an instance of Factory
as well as a valid Request
are needed.

Module
managing the underlying network protocol(s) used by drb.
By default, drb uses the DRbTCPSocket
protocol. Other protocols can be defined. A protocol must define the following class methods:
[open(uri, config)] Open a client connection to the server at +uri+, using configuration +config+. Return a protocol instance for this connection. [open_server(uri, config)] Open a server listening at +uri+, using configuration +config+. Return a protocol instance for this listener. [uri_option(uri, config)] Take a URI, possibly containing an option component (e.g. a trailing '?param=val'), and return a [uri, option] tuple.
All of these methods should raise a DRbBadScheme
error if the URI
does not identify the protocol they support (e.g. “druby:” for the standard Ruby protocol). This is how the DRbProtocol
module, given a URI
, determines which protocol implementation serves that protocol.
The protocol instance returned by open_server
must have the following methods:
Accept a new connection to the server. Returns a protocol instance capable of communicating with the client.
Close the server connection.
Get the URI
for this server.
The protocol instance returned by open
must have the following methods:
Send a request to ref
with the given message id and arguments. This is most easily implemented by calling DRbMessage.send_request, providing a stream that sits on top of the current protocol.
Receive a reply from the server and return it as a [success-boolean, reply-value] pair. This is most easily implemented by calling DRb.recv_reply, providing a stream that sits on top of the current protocol.
Is this connection still alive?
Close this connection.
The protocol instance returned by open_server()
.accept() must have the following methods:
Receive a request from the client and return a [object, message, args, block] tuple. This is most easily implemented by calling DRbMessage.recv_request, providing a stream that sits on top of the current protocol.
Send a reply to the client. This is most easily implemented by calling DRbMessage.send_reply, providing a stream that sits on top of the current protocol.
Close this connection.
A new protocol is registered with the DRbProtocol
module using the add_protocol
method.
For examples of other protocols, see DRbUNIXSocket
in drb/unix.rb, and HTTP0 in sample/http0.rb and sample/http0serv.rb in the full drb distribution.

Mixin methods for security option for Gem::Commands
Module
that defines the default UserInteraction
. Any class including this module will have access to the ui
method that returns the default UI.
UserInteraction
allows RubyGems to interact with the user through standard methods that can be replaced with more-specific UI methods for different displays.
Since UserInteraction
dispatches to a concrete UI class you may need to reference other classes for specific behavior such as Gem::ConsoleUI
or Gem::SilentUI
.
Example:
class X include Gem::UserInteraction def get_answer n = ask("What is the meaning of life?") end end
An SSLContext
is used to set various options regarding certificates, algorithms, verification, session caching, etc. The SSLContext
is used to create an SSLSocket
.
All attributes must be set before creating an SSLSocket
as the SSLContext
will be frozen afterward.
