Results for: "remove_const"

An error class raised when missing nodes are found while computing a constant path’s full name. For example:

Foo

-> raises because the constant path is missing the last part

Raised to stop the iteration, in particular by Enumerator#next. It is rescued by Kernel#loop.

loop do
  puts "Hello"
  raise StopIteration
  puts "World"
end
puts "Done!"

produces:

Hello
Done!

The InstructionSequence class represents a compiled sequence of instructions for the Virtual Machine used in MRI. Not all implementations of Ruby may implement this class, and for the implementations that implement it, the methods defined and behavior of the methods can change in any version.

With it, you can get a handle to the instructions that make up a method or a proc, compile strings of Ruby code down to VM instructions, and disassemble instruction sequences to strings for easy inspection. It is mostly useful if you want to learn how YARV works, but it also lets you control various settings for the Ruby iseq compiler.

You can find the source for the VM instructions in insns.def in the Ruby source.

The instruction sequence results will almost certainly change as Ruby changes, so example output in this documentation may be different from what you see.

Of course, this class is MRI specific.

Mixin methods for install and update options for Gem::Commands

Helper methods for both Gem::Installer and Gem::Uninstaller

FIXME: This isn’t documented in Nutshell.

Since MonitorMixin.new_cond returns a ConditionVariable, and the example above calls while_wait and signal, this class should be documented.

Subclass of StreamUI that instantiates the user interaction using $stdin, $stdout, and $stderr.

ConditionVariable objects augment class Mutex. Using condition variables, it is possible to suspend while in the middle of a critical section until a resource becomes available.

Example:

mutex = Thread::Mutex.new
resource = Thread::ConditionVariable.new

a = Thread.new {
   mutex.synchronize {
     # Thread 'a' now needs the resource
     resource.wait(mutex)
     # 'a' can now have the resource
   }
}

b = Thread.new {
   mutex.synchronize {
     # Thread 'b' has finished using the resource
     resource.signal
   }
}

Raised when memory allocation fails.

Configuration for the openssl library.

Many system’s installation of openssl library will depend on your system configuration. See the value of OpenSSL::Config::DEFAULT_CONFIG_FILE for the location of the file for your host.

See also www.openssl.org/docs/apps/config.html

General error for openssl library configuration files. Including formatting, parsing errors, etc.

Response class for Continue responses (status code 100).

A Continue response indicates that the server has received the request headers.

References:

• Mozilla.

• RFC 9110.

• Wikipedia.

Response class for No Content responses (status code 204).

The No Content response indicates that the server successfully processed the request, and is not returning any content.

References:

• Mozilla.

• RFC 9110.

• Wikipedia.

Response class for Partial Content responses (status code 206).

The Partial Content response indicates that the server is delivering only part of the resource (byte serving) due to a Range header in the request.

References:

• Mozilla.

• RFC 9110.

• Wikipedia.

Response class for Conflict responses (status code 409).

The request could not be processed because of conflict in the current state of the resource.

References:

• Mozilla.

• RFC 9110.

Response class for Insufficient Storage (WebDAV) responses (status code 507).

The server is unable to store the representation needed to complete the request.

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)

Installs a gem along with all its dependencies from local and remote gems.

Raised when there are conflicting gem specs loaded
