Results for: "remove_const"

Calculates the set of unambiguous abbreviations for a given set of strings.

require 'abbrev'
require 'pp'

pp Abbrev.abbrev(['ruby'])
#=>  {"ruby"=>"ruby", "rub"=>"ruby", "ru"=>"ruby", "r"=>"ruby"}

pp Abbrev.abbrev(%w{ ruby rules })

Generates:

{ "ruby"  =>  "ruby",
  "rub"   =>  "ruby",
  "rules" =>  "rules",
  "rule"  =>  "rules",
  "rul"   =>  "rules" }

It also provides an array core extension, Array#abbrev.

pp %w{ summer winter }.abbrev

Generates:

{ "summer"  => "summer",
  "summe"   => "summer",
  "summ"    => "summer",
  "sum"     => "summer",
  "su"      => "summer",
  "s"       => "summer",
  "winter"  => "winter",
  "winte"   => "winter",
  "wint"    => "winter",
  "win"     => "winter",
  "wi"      => "winter",
  "w"       => "winter" }

mkmf.rb is used by Ruby C extensions to generate a Makefile which will correctly compile and link the C extension to Ruby and a third-party library.

RubyGems is the Ruby standard for publishing and managing third party libraries.

RubyGems Plugins

RubyGems will load plugins in the latest version of each installed gem or $LOAD_PATH. Plugins must be named ‘rubygems_plugin’ (.rb, .so, etc) and placed at the root of your gem’s require_path. Plugins are installed at a special location and loaded on boot.

For an example plugin, see the Graph gem which adds a gem graph command.

RubyGems Defaults, Packaging

RubyGems defaults are stored in lib/rubygems/defaults.rb. If you’re packaging RubyGems or implementing Ruby you can change RubyGems’ defaults.

For RubyGems packagers, provide lib/rubygems/defaults/operating_system.rb and override any defaults from lib/rubygems/defaults.rb.

For Ruby implementers, provide lib/rubygems/defaults/#{RUBY_ENGINE}.rb and override any defaults from lib/rubygems/defaults.rb.

If you need RubyGems to perform extra work on install or uninstall, your defaults override file can set pre/post install and uninstall hooks. See Gem::pre_install, Gem::pre_uninstall, Gem::post_install, Gem::post_uninstall.

You can submit bugs to the RubyGems bug tracker on GitHub

Secure random number generator interface.

This library is an interface to secure random number generators which are suitable for generating session keys in HTTP cookies, etc.

You can use this library in your application by requiring it:

require 'securerandom'

It supports the following secure random number generators:

• openssl

• /dev/urandom

• Win32

SecureRandom is extended by the Random::Formatter module which defines the following methods:

• alphanumeric

• base64

• choose

• gen_random

• hex

• rand

• random_bytes

• random_number

• urlsafe_base64

• uuid

These methods are usable as class methods of SecureRandom such as SecureRandom.hex.

If a secure random number generator is not available, NotImplementedError is raised.

exception to wait for reading by EINPROGRESS. see IO.select.

Raised on redirection, only occurs when redirect option for HTTP is false.

Indicates a failure to resolve a name or address.

This Gem::StreamUI subclass records input and output to StringIO for retrieval during tests.

Given a set of Gem::Dependency objects as needed and a way to query the set of available specs via set, calculates a set of ActivationRequest objects which indicate all the specs that should be activated to meet the all the requirements.

Raised by Encoding and String methods when the source encoding is incompatible with the target encoding.

Description

A representation of a C function

Examples

‘strcpy’

@libc = Fiddle.dlopen "/lib/libc.so.6"
   #=> #<Fiddle::Handle:0x00000001d7a8d8>
f = Fiddle::Function.new(
  @libc['strcpy'],
  [Fiddle::TYPE_VOIDP, Fiddle::TYPE_VOIDP],
  Fiddle::TYPE_VOIDP)
   #=> #<Fiddle::Function:0x00000001d8ee00>
buff = "000"
   #=> "000"
str = f.call(buff, "123")
   #=> #<Fiddle::Pointer:0x00000001d0c380 ptr=0x000000018a21b8 size=0 free=0x00000000000000>
str.to_s
=> "123"

ABI check

@libc = Fiddle.dlopen "/lib/libc.so.6"
   #=> #<Fiddle::Handle:0x00000001d7a8d8>
f = Fiddle::Function.new(@libc['strcpy'], [TYPE_VOIDP, TYPE_VOIDP], TYPE_VOIDP)
   #=> #<Fiddle::Function:0x00000001d8ee00>
f.abi == Fiddle::Function::DEFAULT
   #=> true
