Gets the global do_not_reverse_lookup flag.

BasicSocket.do_not_reverse_lookup  #=> false

Sets the global do_not_reverse_lookup flag.

The flag is used for initial value of do_not_reverse_lookup for each socket.

s1 = TCPSocket.new("localhost", 80)
p s1.do_not_reverse_lookup                 #=> true
BasicSocket.do_not_reverse_lookup = false
s2 = TCPSocket.new("localhost", 80)
p s2.do_not_reverse_lookup                 #=> false
p s1.do_not_reverse_lookup                 #=> true

Gets the do_not_reverse_lookup flag of basicsocket.

require 'socket'

BasicSocket.do_not_reverse_lookup = false
TCPSocket.open("www.ruby-lang.org", 80) {|sock|
  p sock.do_not_reverse_lookup      #=> false
}
BasicSocket.do_not_reverse_lookup = true
TCPSocket.open("www.ruby-lang.org", 80) {|sock|
  p sock.do_not_reverse_lookup      #=> true
}

Sets the do_not_reverse_lookup flag of basicsocket.

TCPSocket.open("www.ruby-lang.org", 80) {|sock|
  p sock.do_not_reverse_lookup       #=> true
  p sock.peeraddr                    #=> ["AF_INET", 80, "221.186.184.68", "221.186.184.68"]
  sock.do_not_reverse_lookup = false
  p sock.peeraddr                    #=> ["AF_INET", 80, "carbon.ruby-lang.org", "54.163.249.195"]

Sets the basic list of characters that signal a break between words for rl_complete_internal(). The default is the value of Readline.basic_word_break_characters.

Raises NotImplementedError if the using readline library does not support.

Gets the basic list of characters that signal a break between words for rl_complete_internal().

Raises NotImplementedError if the using readline library does not support.

The index to insert activated gem paths into the $LOAD_PATH. The activated gem’s paths are inserted before site lib directory by default.

Like Enumerable#filter_map, but chains operation to be lazy-evaluated.

(1..).lazy.filter_map { |i| i * 2 if i.even? }.first(5)
#=> [4, 8, 12, 16, 20]
