A Source knows how to list and fetch gems from a RubyGems marshal index.

There are other Source subclasses for installed gems, local gems, the bundler dependency API and so-forth.

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'
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.

Gem::StubSpecification reads the stub: line from the gemspec. This prevents us having to eval the entire gemspec in order to find out certain information.

Validator performs various gem file and gem database validation

In order to execute a command on your OS, you need to define it as a Shell method.

Alternatively, you can execute any command via Shell::CommandProcessor#system even if it is not defined.

Not a URI.

Not a URI component.

Base class for all URI classes. Implements generic URI syntax as per RFC 2396.

A generic logging class

Base TCP server class. You must subclass GenericServer and provide a run method.

Provides remote procedure calls to a XML-RPC server.

After setting the connection-parameters with XMLRPC::Client.new which creates a new XMLRPC::Client instance, you can execute a remote procedure by sending the XMLRPC::Client#call or XMLRPC::Client#call2 message to this new instance.

The given parameters indicate which method to call on the remote-side and of course the parameters for the remote procedure.

require "xmlrpc/client"

server = XMLRPC::Client.new("www.ruby-lang.org", "/RPC2", 80)
begin
  param = server.call("michael.add", 4, 5)
  puts "4 + 5 = #{param}"
rescue XMLRPC::FaultException => e
  puts "Error:"
  puts e.faultCode
  puts e.faultString
end

or

require "xmlrpc/client"

server = XMLRPC::Client.new("www.ruby-lang.org", "/RPC2", 80)
ok, param = server.call2("michael.add", 4, 5)
if ok then
  puts "4 + 5 = #{param}"
else
  puts "Error:"
  puts param.faultCode
  puts param.faultString
end

Raised when the remote procedure returns a fault-structure, which has two accessor-methods faultCode an Integer, and faultString a String.

This is the base class for all XML-RPC server-types (CGI, standalone). You can add handler and set a default handler. Do not use this server, as this is/should be an abstract class.

How the method to call is found

The arity (number of accepted arguments) of a handler (method or Proc object) is compared to the given arguments submitted by the client for a RPC, or Remote Procedure Call.

A handler is only called if it accepts the number of arguments, otherwise the search for another handler will go on. When at the end no handler was found, the default_handler, XMLRPC::BasicServer#set_default_handler will be called.

With this technique it is possible to do overloading by number of parameters, but only for Proc handler, because you cannot define two methods of the same name in the same class.

Implements a servlet for use with WEBrick, a pure Ruby (HTTP) server framework.

require "webrick"
require "xmlrpc/server"

s = XMLRPC::WEBrickServlet.new
s.add_handler("michael.add") do |a,b|
  a + b
end

s.add_handler("michael.div") do |a,b|
  if b == 0
    raise XMLRPC::FaultException.new(1, "division by zero")
  else
    a / b
  end
end

s.set_default_handler do |name, *args|
  raise XMLRPC::FaultException.new(-99, "Method #{name} missing" +
                                   " or wrong number of parameters!")
end

httpserver = WEBrick::HTTPServer.new(:Port => 8080)
httpserver.mount("/RPC2", s)
trap("HUP") { httpserver.shutdown }   # use 1 instead of "HUP" on Windows
httpserver.start

This module provides instance methods for a digest implementation object to calculate message digest values.

Adds basic type aliases to the including class for use with Fiddle::Importer.

The aliases added are uint and u_int (unsigned int) and ulong and u_long (unsigned long)

Use SSLContext to set up the parameters for a TLS (former SSL) connection. Both client and server TLS connections are supported, SSLSocket and SSLServer may be used in conjunction with an instance of SSLContext to set up connections.

let rdoc know about mOSSL

Net::HTTP exception class. You cannot use Net::HTTPExceptions directly; instead, you must use its subclasses.

Acceptable argument classes. Now contains DecimalInteger, OctalInteger and DecimalNumeric. See Acceptable argument classes (in source code).

Adds named attributes to an object.
