Return the name associated with this NameError exception.
Returns the name of the module mod. Returns nil for anonymous modules.
Returns pathname configuration variable using fpathconf().
name should be a constant under Etc which begins with PC_.
The return value is an integer or nil. nil means indefinite limit. (fpathconf() returns -1 but errno is not set.)

Obtains name information for sockaddr.
sockaddr should be one of follows.
packed sockaddr string such as Socket.sockaddr_in(80, “127.0.0.1”)
3-elements array such as [“AF_INET”, 80, “127.0.0.1”]
4-elements array such as [“AF_INET”, 80, ignored, “127.0.0.1”]
flags should be bitwise OR of Socket::NI_* constants.
Note: The last form is compatible with IPSocket#addr and IPSocket#peeraddr.
Socket.getnameinfo(Socket.sockaddr_in(80, "127.0.0.1")) #=> ["localhost", "www"] Socket.getnameinfo(["AF_INET", 80, "127.0.0.1"]) #=> ["localhost", "www"] Socket.getnameinfo(["AF_INET", 80, "localhost", "127.0.0.1"]) #=> ["localhost", "www"]
If Addrinfo object is preferred, use Addrinfo#getnameinfo.
Returns the local address of the socket as a sockaddr string.
TCPServer.open("127.0.0.1", 15120) {|serv| p serv.getsockname #=> "\x02\x00;\x10\x7F\x00\x00\x01\x00\x00\x00\x00\x00\x00\x00\x00" }
If Addrinfo object is preferred over the binary string, use BasicSocket#local_address.
Returns the remote address of the socket as a sockaddr string.
TCPServer.open("127.0.0.1", 1440) {|serv| c = TCPSocket.new("127.0.0.1", 1440) s = serv.accept p s.getpeername #=> "\x02\x00\x82u\x7F\x00\x00\x01\x00\x00\x00\x00\x00\x00\x00\x00" }
If Addrinfo object is preferred over the binary string, use BasicSocket#remote_address.
returns the canonical name as an string.
nil is returned if no canonical name.
The canonical name is set by Addrinfo.getaddrinfo when AI_CANONNAME is specified.
list = Addrinfo.getaddrinfo("www.ruby-lang.org", 80, :INET, :STREAM, nil, Socket::AI_CANONNAME) p list[0] #=> #<Addrinfo: 221.186.184.68:80 TCP carbon.ruby-lang.org (www.ruby-lang.org)> p list[0].canonname #=> "carbon.ruby-lang.org"
returns nodename and service as a pair of strings. This converts struct sockaddr in addrinfo to textual representation.
flags should be bitwise OR of Socket::NI_??? constants.
Addrinfo.tcp("127.0.0.1", 80).getnameinfo #=> ["localhost", "www"] Addrinfo.tcp("127.0.0.1", 80).getnameinfo(Socket::NI_NUMERICSERV) #=> ["localhost", "80"]
Returns the path of the local address of unixsocket.
s = UNIXServer.new("/tmp/sock") p s.path #=> "/tmp/sock"
call-seq
WIN32OLE_METHOD#name
Returns the name of the method.
tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbook') method = WIN32OLE_METHOD.new(tobj, 'SaveAs') puts method.name # => SaveAs
Returns name.
tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Workbook') method = WIN32OLE_METHOD.new(tobj, 'SaveAs') param1 = method.params[0] puts param1.name # => Filename
Returns the type name of VT_RECORD OLE variable.
If COM server in VB.NET ComServer project is the following:
Imports System.Runtime.InteropServices
Public Class ComClass
Public Structure Book
<MarshalAs(UnmanagedType.BStr)> _
Public title As String
Public cost As Integer
End Structure
Public Function getBook() As Book
Dim book As New Book
book.title = "The Ruby Book"
book.cost = 20
Return book
End Function
End Class
then, the result of WIN32OLE_RECORD#typename is the following:
require 'win32ole' obj = WIN32OLE.new('ComServer.ComClass') book = obj.getBook book.typename # => "Book"
Returns OLE type name.
tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Application') puts tobj.name # => Application
Returns the type library name.
tlib = WIN32OLE_TYPELIB.new('Microsoft Excel 9.0 Object Library') name = tlib.name # -> 'Microsoft Excel 9.0 Object Library'
Returns the type library file path.
tlib = WIN32OLE_TYPELIB.new('Microsoft Excel 9.0 Object Library') puts tlib.path #-> 'C:\...\EXCEL9.OLB'
Returns the name of variable.
tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'XlSheetType') variables = tobj.variables variables.each do |variable| puts "#{variable.name}" end The result of above script is following: xlChart xlDialogSheet xlExcel4IntlMacroSheet xlExcel4MacroSheet xlWorksheet
Returns the current filename. “-” is returned when the current file is STDIN.
For example:
$ echo "foo" > foo $ echo "bar" > bar $ echo "glark" > glark $ ruby argf.rb foo bar glark ARGF.filename #=> "foo" ARGF.read(5) #=> "foo\nb" ARGF.filename #=> "bar" ARGF.skip ARGF.filename #=> "glark"
Returns the current filename. “-” is returned when the current file is STDIN.
For example:
$ echo "foo" > foo $ echo "bar" > bar $ echo "glark" > glark $ ruby argf.rb foo bar glark ARGF.filename #=> "foo" ARGF.read(5) #=> "foo\nb" ARGF.filename #=> "bar" ARGF.skip ARGF.filename #=> "glark"
Returns a list of names of captures as an array of strings. It is same as mtch.regexp.names.
/(?<foo>.)(?<bar>.)(?<baz>.)/.match("hoge").names #=> ["foo", "bar", "baz"] m = /(?<x>.)(?<y>.)?/.match("a") #=> #<MatchData "a" x:"a" y:nil> m.names #=> ["x", "y"]
Returns the path to the data store file.
Looks up the hostname of address.
