Potentially raised when a specification is validated.
Raised by Gem::Validator when something is not right in a gem.
Raised by Resolver when a dependency requests a gem for which there is no spec.
A test case for Gem::Installer.
Gem::PathSupport facilitates the GEM_HOME and GEM_PATH environment settings to the rest of RubyGems.
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.
RubyGemTestCase provides a variety of methods for testing rubygems and gem-related behavior in a sandbox. Through RubyGemTestCase you can install and uninstall gems, fetch remote gems through a stub fetcher and be assured your normal set of gems is not affected.
Validator performs various gem file and gem database validation
RFC6068, the mailto URL scheme.
Raised when a mathematical function is evaluated outside of its domain of definition.
For example, since cos returns values in the range -1..1, its inverse function acos is only defined on that interval:
Math.acos(42)
produces:
Math::DomainError: Numerical argument is out of domain - "acos"
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.
This module contains configuration information about the SSL extension, for example if socket support is enabled, or the host name TLS extension is enabled. Constants in this module will always be defined, but contain true or false values depending on the configuration of your OpenSSL installation.
Atom is an XML-based document format that is used to describe ‘feeds’ of related information. A typical use is in a news feed where the information is periodically updated and which users can subscribe to. The Atom format is described in tools.ietf.org/html/rfc4287
The Atom module provides support in reading and creating feeds.
See the RSS module for examples consuming and creating feeds.
Provides a set of builders for various RSS objects
