Attempts to activate the current {#possibility} (given that it has already been activated) @return [void]

Performs elliptic curve point multiplication.

The first form calculates bn1 * point + bn2 * G, where G is the generator of the group of point. bn2 may be omitted, and in that case, the result is just bn1 * point.

The second form calculates bns[0] * point + bns[1] * points[0] + ... + bns[-1] * points[-1] + bn2 * G. bn2 may be omitted. bns must be an array of OpenSSL::BN. points must be an array of OpenSSL::PKey::EC::Point. Please note that points[0] is not multiplied by bns[0], but bns[1].

Is this tar entry a file?

Returns true for IPv6 multicast node-local scope address. It returns false otherwise.

Displays helpfile. The 1st argument specifies WIN32OLE_TYPE object or WIN32OLE_METHOD object or helpfile.

excel = WIN32OLE.new('Excel.Application')
typeobj = excel.ole_type
WIN32OLE.ole_show_help(typeobj)

Returns WIN32OLE object for a specific dispatch or dual interface specified by iid.

ie = WIN32OLE.new('InternetExplorer.Application')
ie_web_app = ie.ole_query_interface('{0002DF05-0000-0000-C000-000000000046}') # => WIN32OLE object for dispinterface IWebBrowserApp

Returns WIN32OLE_TYPE object.

excel = WIN32OLE.new('Excel.Application')
tobj = excel.ole_type

Returns detail information of type of argument.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'IWorksheetFunction')
method = WIN32OLE_METHOD.new(tobj, 'SumIf')
param1 = method.params[0]
p param1.ole_type_detail # => ["PTR", "USERDEFINED", "Range"]

Returns the array of WIN32OLE_TYPE object which is implemented by the WIN32OLE_TYPE object and having IMPLTYPEFLAG_FSOURCE.

tobj = WIN32OLE_TYPE.new('Microsoft Internet Controls', "InternetExplorer")
p tobj.source_ole_types
# => [#<WIN32OLE_TYPE:DWebBrowserEvents2>, #<WIN32OLE_TYPE:DWebBrowserEvents>]

Returns the array of WIN32OLE_TYPE object which is implemented by the WIN32OLE_TYPE object and having IMPLTYPEFLAG_FSOURCE and IMPLTYPEFLAG_FDEFAULT.

tobj = WIN32OLE_TYPE.new('Microsoft Internet Controls', "InternetExplorer")
p tobj.default_event_sources  # => [#<WIN32OLE_TYPE:DWebBrowserEvents2>]

Returns detail information of type. The information is array of type.

tobj = WIN32OLE_TYPE.new('DirectX 7 for Visual Basic Type Library', 'D3DCLIPSTATUS')
variable = tobj.variables.find {|variable| variable.name == 'lFlags'}
tdetail  = variable.ole_type_detail
p tdetail # => ["USERDEFINED", "CONST_D3DCLIPSTATUSFLAGS"]

Render a template on a new toplevel binding with local variables specified by a Hash object.

Returns the value of the local variable symbol.

def foo
  a = 1
  binding.local_variable_get(:a) #=> 1
  binding.local_variable_get(:b) #=> NameError
end

This method is the short version of the following code:

binding.eval("#{symbol}")

Set local variable named symbol as obj.

def foo
  a = 1
  bind = binding
  bind.local_variable_set(:a, 2) # set existing local variable `a'
  bind.local_variable_set(:b, 3) # create new local variable `b'
                                 # `b' exists only in binding

  p bind.local_variable_get(:a)  #=> 2
  p bind.local_variable_get(:b)  #=> 3
  p a                            #=> 2
  p b                            #=> NameError
end

This method behaves similarly to the following code:

binding.eval("#{symbol} = #{obj}")

if obj can be dumped in Ruby code.

Returns true if a local variable symbol exists.

def foo
  a = 1
  binding.local_variable_defined?(:a) #=> true
  binding.local_variable_defined?(:b) #=> false
end

This method is the short version of the following code:

binding.eval("defined?(#{symbol}) == 'local-variable'")

Breaks the buffer into lines that are shorter than maxwidth

Returns the directories in the current shell’s PATH environment variable as an array of directory names. This sets the system_path for all instances of Shell.

Example: If in your current shell, you did:

$ echo $PATH
/usr/bin:/bin:/usr/local/bin

Running this method in the above shell would then return:

["/usr/bin", "/bin", "/usr/local/bin"]

Sets the system_path that new instances of Shell should have as their initial system_path.

path should be an array of directory name strings.

Returns the value of a thread local variable that has been set. Note that these are different than fiber local values. For fiber local values, please see Thread#[] and Thread#[]=.

Thread local values are carried along with threads, and do not respect fibers. For example:

Thread.new {
  Thread.current.thread_variable_set("foo", "bar") # set a thread local
  Thread.current["foo"] = "bar"                    # set a fiber local

  Fiber.new {
    Fiber.yield [
      Thread.current.thread_variable_get("foo"), # get the thread local
      Thread.current["foo"],                     # get the fiber local
    ]
  }.resume
}.join.value # => ['bar', nil]

The value “bar” is returned for the thread local, where nil is returned for the fiber local. The fiber is executed in the same thread, so the thread local values are available.

Sets a thread local with key to value. Note that these are local to threads, and not to fibers. Please see Thread#thread_variable_get and Thread#[] for more information.
