Results for: "OptionParser"

A mixin that provides methods for parsing C struct and prototype signatures.

Example

require 'fiddle/import'

include Fiddle::CParser
  #=> Object

parse_ctype('int')
  #=> Fiddle::TYPE_INT

parse_struct_signature(['int i', 'char c'])
  #=> [[Fiddle::TYPE_INT, Fiddle::TYPE_CHAR], ["i", "c"]]

parse_signature('double sum(double, double)')
  #=> ["sum", Fiddle::TYPE_DOUBLE, [Fiddle::TYPE_DOUBLE, Fiddle::TYPE_DOUBLE]]

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

Mixin methods for local and remote Gem::Command options.

WIN32OLE_PARAM objects represent param information of the OLE method.

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.

This class is equivalent to POP3, except that it uses APOP authentication.

This is an abstract class. You never use this directly; it serves as a parent class for the specific declarations.

Base exception class for RubyGems. All exception raised by RubyGems are a subclass of this one.

Raised by Gem::Resolver when a Gem::Dependency::Conflict reaches the toplevel. Indicates which dependencies were incompatible through conflict and conflicting_dependencies

Potentially raised when a specification is validated.

Signals that a file permission error is preventing the user from operating on the given directory.

Used to raise parsing and loading errors
