TupleSpaceProxy allows a remote Tuplespace to appear as local.

Documentation?

The Tuplespace manages access to the tuples it contains, ensuring mutual exclusion requirements are met.

The sec option for the write, take, move, read and notify methods may either be a number of seconds or a Renewer object.

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

:concurrent_downloads

See concurrent_downloads

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

• system wide (/etc/gemrc)

• per user (~/.gemrc)

• per environment (gemrc files listed in the GEMRC environment variable)

Raised when there are conflicting gem specs loaded

Example using a Gem::Package

Builds a .gem file given a Gem::Specification. A .gem file is a tarball which contains a data.tar.gz, metadata.gz, checksums.yaml.gz and possibly signatures.

require 'rubygems'
require 'rubygems/package'

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::Package.build spec

Reads a .gem file.

require 'rubygems'
require 'rubygems/package'

the_gem = Gem::Package.new(path_to_dot_gem)
the_gem.contents # get the files in the gem
the_gem.extract_files destination_directory # extract the gem into a directory
the_gem.spec # get the spec out of the gem
the_gem.verify # check the gem is OK (contains valid gem specification, contains a not corrupt contents archive)

files are the files in the .gem tar file, not the Ruby files in the gem extract_files and contents automatically call verify

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

Subclass of StreamUI that instantiates the user interaction using STDIN, STDOUT, and STDERR.

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.

A DSL that provides the means to dynamically load libraries and build modules around them including calling extern functions within the C library that has been loaded.

Example

require 'fiddle'
require 'fiddle/import'

module LibSum
  extend Fiddle::Importer
  dlload './libsum.so'
  extern 'double sum(double*, int)'
  extern 'double split(double)'
end

exception to wait for reading. see IO.select.

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.

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.

The WIN32OLE::VARIANT module includes constants of VARIANT type constants. The constants is used when creating WIN32OLE_VARIANT object.

obj = WIN32OLE_VARIANT.new("2e3", WIN32OLE::VARIANT::VT_R4)
obj.value # => 2000.0

This module has all methods of FileUtils module, but never changes files/directories. This equates to passing the :noop flag to methods in FileUtils.
