Returns the destination encoding as an encoding object.

Returns the destination encoding as an Encoding object.

Consumes size bytes from the buffer

Returns a list of encodings in Content-Encoding field as an array of strings.

The encodings are downcased for canonicalization.

Invoked as a callback whenever an instance method is removed from the receiver.

module Chatty
  def self.method_removed(method_name)
    puts "Removing #{method_name.inspect}"
  end
  def self.some_class_method() end
  def some_instance_method() end
  class << self
    remove_method :some_class_method
  end
  remove_method :some_instance_method
end

produces:

Removing :some_instance_method

Add the install/update options to the option parser.

Starts tracing object allocations.

Stop tracing object allocations.

Note that if ::trace_object_allocations_start is called n-times, then tracing will stop after calling ::trace_object_allocations_stop n-times.

Encodes given str to URL-encoded form data.

This method doesn’t convert *, -, ., 0-9, A-Z, _, a-z, but does convert SP (ASCII space) to + and converts others to %XX.

If enc is given, convert str to the encoding before percent encoding.

This is an implementation of www.w3.org/TR/2013/CR-html5-20130806/forms.html#url-encoded-form-data.

See URI.decode_www_form_component, URI.encode_www_form.

Decodes given str of URL-encoded form data.

This decodes + to SP.

See URI.encode_www_form_component, URI.decode_www_form.

Gets X509v3 extensions as array of X509Ext objects

Sets X509_EXTENSIONs

Gets X509v3 extensions as array of X509Ext objects

Sets X509_EXTENSIONs

Returns an array of instance variable names for the receiver. Note that simply defining an accessor does not create the corresponding instance variable.

class Fred
  attr_accessor :a1
  def initialize
    @iv = 3
  end
end
Fred.new.instance_variables   #=> [:@iv]

Returns true if obj is an instance of the given class. See also Object#kind_of?.

class A;     end
class B < A; end
class C < B; end

b = B.new
b.instance_of? A   #=> false
b.instance_of? B   #=> true
b.instance_of? C   #=> false

Like backtrace, but returns each line of the execution stack as a Thread::Backtrace::Location. Accepts the same arguments as backtrace.

f = Fiber.new { Fiber.yield }
f.resume
loc = f.backtrace_locations.first
loc.label  #=> "yield"
loc.path   #=> "test.rb"
loc.lineno #=> 1

Returns any backtrace associated with the exception. This method is similar to Exception#backtrace, but the backtrace is an array of Thread::Backtrace::Location.

This method is not affected by Exception#set_backtrace().

Returns an array containing the names of the public and protected instance methods in the receiver. For a module, these are the public and protected methods; for a class, they are the instance (not singleton) methods. If the optional parameter is false, the methods of any ancestors are not included.

module A
  def method1()  end
end
class B
  include A
  def method2()  end
end
class C < B
  def method3()  end
end

A.instance_methods(false)                   #=> [:method1]
B.instance_methods(false)                   #=> [:method2]
B.instance_methods(true).include?(:method1) #=> true
C.instance_methods(false)                   #=> [:method3]
C.instance_methods.include?(:method2)       #=> true

Returns an UnboundMethod representing the given instance method in mod.

class Interpreter
  def do_a() print "there, "; end
  def do_d() print "Hello ";  end
  def do_e() print "!\n";     end
  def do_v() print "Dave";    end
  Dispatcher = {
    "a" => instance_method(:do_a),
    "d" => instance_method(:do_d),
    "e" => instance_method(:do_e),
    "v" => instance_method(:do_v)
  }
  def interpret(string)
    string.each_char {|b| Dispatcher[b].bind(self).call }
  end
end

interpreter = Interpreter.new
interpreter.interpret('dave')

produces:

Hello there, Dave!
