Change the current process’s real and effective user ID to that specified by user. Returns the new user ID. Not available on all platforms.
[Process.uid, Process.euid] #=> [0, 0] Process::UID.change_privilege(31) #=> 31 [Process.uid, Process.euid] #=> [31, 31]
Change the current process’s real and effective group ID to that specified by group. Returns the new group ID. Not available on all platforms.
[Process.gid, Process.egid] #=> [0, 0] Process::GID.change_privilege(33) #=> 33 [Process.gid, Process.egid] #=> [33, 33]
Check if --yjit-log is used.
Creates a new DH instance from scratch by generating random parameters and a key pair.

size
The desired key size in bits.
generator
The generator.
Creates a new DSA instance by generating a private/public key pair from scratch.

size
The desired key size in bits.
Creates a new EC instance with a new random private and public key.
Generates an RSA keypair.
See also OpenSSL::PKey.generate_key.
size
The desired key size in bits.
exponent
An odd Integer, normally 3, 17, or 65537.
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"] }
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]
When a call node has the attribute_write flag set, it means that the call is using the attribute write syntax. This is either a method call to []= or a method call to a method that ends with =. Either way, the = sign is present in the source.
Prism returns the message_loc without the = sign attached, because there can be any amount of space between the message and the = sign. However, sometimes you want the location of the full message including the inner space and the = sign. This method provides that.
Creates windows .bat files for easy running of commands
Creates the scripts to run the applications in the gem.
Creates the symlinks to run the applications in the gem. Moves the symlink if the gem being installed has a newer version.
