Class for reading entries out of a tar file

A state that encapsulates a set of {#requirements} with an {Array} of possibilities

A state that encapsulates a single possibility to fulfill the given {#requirement}

module IN contains ARPA Internet specific RRs.

Delegates all {Gem::Resolver::Molinillo::ResolutionState} methods to a ‘#state` property.

Changes underlying String object, the subject of IO.

Changes the string being scanned to str and resets the scanner. Returns str.

Returns help string of OLE method. If the help string is not found, then the method returns nil.

tobj = WIN32OLE_TYPE.new('Microsoft Internet Controls', 'IWebBrowser')
method = WIN32OLE_METHOD.new(tobj, 'Navigate')
puts method.helpstring # => Navigates to a URL or file.

Returns help string.

tobj = WIN32OLE_TYPE.new('Microsoft Internet Controls', 'IWebBrowser')
puts tobj.helpstring # => Web Browser interface

Adds a post-installs hook that will be passed a Gem::DependencyInstaller and a list of installed specifications when Gem::DependencyInstaller#install is complete

Returns the list of Modules nested at the point of call.

module M1
  module M2
    $a = Module.nesting
  end
end
$a           #=> [M1::M2, M1]
$a[0].name   #=> "M1::M2"

Set the handling of the ordering of options and arguments. A RuntimeError is raised if option processing has already started.

The supplied value must be a member of GetoptLong::ORDERINGS. It alters the processing of options as follows:

REQUIRE_ORDER :

Options are required to occur before non-options.

Processing of options ends as soon as a word is encountered that has not been preceded by an appropriate option flag.

For example, if -a and -b are options which do not take arguments, parsing command line arguments of ‘-a one -b two’ would result in ‘one’, ‘-b’, ‘two’ being left in ARGV, and only (‘-a’, ”) being processed as an option/arg pair.

This is the default ordering, if the environment variable POSIXLY_CORRECT is set. (This is for compatibility with GNU getopt_long.)

PERMUTE :

Options can occur anywhere in the command line parsed. This is the default behavior.

Every sequence of words which can be interpreted as an option (with or without argument) is treated as an option; non-option words are skipped.

For example, if -a does not require an argument and -b optionally takes an argument, parsing ‘-a one -b two three’ would result in (‘-a’,”) and (‘-b’, ‘two’) being processed as option/arg pairs, and ‘one’,‘three’ being left in ARGV.

If the ordering is set to PERMUTE but the environment variable POSIXLY_CORRECT is set, REQUIRE_ORDER is used instead. This is for compatibility with GNU getopt_long.

RETURN_IN_ORDER :

All words on the command line are processed as options. Words not preceded by a short or long option flag are passed as arguments with an option of ” (empty string).

For example, if -a requires an argument but -b does not, a command line of ‘-a one -b two three’ would result in option/arg pairs of (‘-a’, ‘one’) (‘-b’, ”), (”, ‘two’), (”, ‘three’) being processed.

Returns the binding associated with prc.

def fred(param)
  proc {}
end

b = fred(99)
eval("param", b.binding)   #=> 99

Return the generated binding object from event

Returns a Binding object, describing the variable and method bindings at the point of call. This object can be used when calling eval to execute the evaluated command in this environment. See also the description of class Binding.

def get_binding(param)
  binding
end
b = get_binding("hello")
eval("param", b)   #=> "hello"

Is this handler a streaming handler?

Returns true if the given instance variable is defined in obj. String arguments are converted to symbols.

class Fred
  def initialize(p1, p2)
    @a, @b = p1, p2
  end
end
fred = Fred.new('cat', 99)
fred.instance_variable_defined?(:@a)    #=> true
fred.instance_variable_defined?("@b")   #=> true
fred.instance_variable_defined?("@c")   #=> false

Returns true if and only if the scan pointer is at the beginning of the line.

s = StringScanner.new("test\ntest\n")
s.bol?           # => true
s.scan(/te/)
s.bol?           # => false
s.scan(/st\n/)
s.bol?           # => true
s.terminate
s.bol?           # => true

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]
