The InvalidRSSError error is the base class for a variety of errors related to a poorly-formed RSS feed. Rescue this error if you only care that a file could be invalid, but don’t care how it is invalid.

Since RSS is based on XML, it must have opening and closing tags that match. If they don’t, a MissingTagError will be raised.

Some tags must only exist a specific number of times in a given RSS feed. If a feed has too many occurrences of one of these tags, a TooMuchTagError will be raised.

RSS does not allow for free-form tag names, so if an RSS feed contains a tag that we don’t know about, an UnknownTagError is raised.

Raised when an unexpected tag is encountered.

Potentially raised when a specification is validated.

Create a package based upon a Gem::Specification. Gem packages, as well as zip files and tar/gzipped packages can be produced by this task.

In addition to the Rake targets generated by Rake::PackageTask, a Gem::PackageTask will also generate the following tasks:

“package_dir/name-version.gem”

Create a RubyGems package with the given name and version.

Example using a Gem::Specification:

require 'rubygems'
require 'rubygems/package_task'

spec = Gem::Specification.new do |s|
  s.summary = "Ruby based make-like utility."
  s.name = 'rake'
  s.version = PKG_VERSION
  s.requirements << 'none'
  s.files = PKG_FILES
  s.description = <<-EOF
Rake is a Make-like program implemented in Ruby. Tasks
and dependencies are specified in standard Ruby syntax.
  EOF
end

Gem::PackageTask.new(spec) do |pkg|
  pkg.need_zip = true
  pkg.need_tar = true
end

Validator performs various gem file and gem database validation

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.

Raised by Encoding and String methods when the string being transcoded contains a byte invalid for the either the source or target encoding.

AbstractSyntaxTree provides methods to parse Ruby code into abstract syntax trees. The nodes in the tree are instances of RubyVM::AbstractSyntaxTree::Node.

This class is MRI specific as it exposes implementation details of the MRI abstract syntax tree.

This class is experimental and its API is not stable, therefore it might change without notice. As examples, the order of children nodes is not guaranteed, the number of children nodes might change, there is no way to access children nodes by name, etc.

If you are looking for a stable API or an API working under multiple Ruby implementations, consider using the parser gem or Ripper. If you would like to make RubyVM::AbstractSyntaxTree stable, please join the discussion at bugs.ruby-lang.org/issues/14844.

File::Constants provides file-related constants. All possible file constants are listed in the documentation but they may not all be present on your platform.

If the underlying platform doesn’t define a constant the corresponding Ruby constant is not defined.

Your platform documentations (e.g. man open(2)) may describe more detailed information.

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

exception to wait for writing. see IO.select.

Socket::Constants provides socket-related constants. All possible socket constants are listed in the documentation but they may not all be present on your platform.

If the underlying platform doesn’t define a constant the corresponding Ruby constant is not defined.
