Extracts addr and ifindex from IPV6_PKTINFO ancillary data.

IPV6_PKTINFO is defined by RFC 3542.

addr = Addrinfo.ip("::1")
ifindex = 0
ancdata = Socket::AncillaryData.ipv6_pktinfo(addr, ifindex)
p ancdata.ipv6_pktinfo #=> [#<Addrinfo: ::1>, 0]

Write value to a registry value named name.

The value type is REG_SZ(write_s), REG_DWORD(write_i), or REG_BINARY(write_bin).

Returns variable kind string.

tobj = WIN32OLE::Type.new('Microsoft Excel 9.0 Object Library', 'XlSheetType')
variables = tobj.variables
variables.each do |variable|
  puts "#{variable.name} #{variable.variable_kind}"
end

The result of above script is following:
  xlChart CONSTANT
  xlDialogSheet CONSTANT
  xlExcel4IntlMacroSheet CONSTANT
  xlExcel4MacroSheet CONSTANT
  xlWorksheet CONSTANT

Returns original filename recorded in the gzip file header, or nil if original filename is not present.

Specify the original name (str) in the gzip header.

Returns true if stat is writable by the real user id of this process.

File.stat("testfile").writable_real?   #=> true

If stat is writable by others, returns an integer representing the file permission bits of stat. Returns nil otherwise. The meaning of the bits is platform dependent; on Unix systems, see stat(2).

m = File.stat("/tmp").world_writable?         #=> 511
sprintf("%o", m)                              #=> "777"

Returns the number of the first source line where the instruction sequence was loaded from.

For example, using irb:

iseq = RubyVM::InstructionSequence.compile('num = 1 + 2')
#=> <RubyVM::InstructionSequence:<compiled>@<compiled>>
iseq.first_lineno
#=> 1

Return trace points in the instruction sequence. Return an array of [line, event_symbol] pair.

Takes source, which can be a string of Ruby code, or an open File object. that contains Ruby source code. It parses and compiles using prism.

Optionally takes file, path, and line which describe the file path, real path and first line number of the ruby code in source which are metadata attached to the returned iseq.

file is used for ‘__FILE__` and exception backtrace. path is used for require_relative base. It is recommended these should be the same full path.

options, which can be true, false or a Hash, is used to modify the default behavior of the Ruby iseq compiler.

For details regarding valid compile options see ::compile_option=.

RubyVM::InstructionSequence.compile("a = 1 + 2")
#=> <RubyVM::InstructionSequence:<compiled>@<compiled>>

path = "test.rb"
RubyVM::InstructionSequence.compile(File.read(path), path, File.expand_path(path))
#=> <RubyVM::InstructionSequence:<compiled>@test.rb:1>

file = File.open("test.rb")
RubyVM::InstructionSequence.compile(file)
#=> <RubyVM::InstructionSequence:<compiled>@<compiled>:1>

path = File.expand_path("test.rb")
RubyVM::InstructionSequence.compile(File.read(path), path, path)
#=> <RubyVM::InstructionSequence:<compiled>@/absolute/path/to/test.rb:1>

Take a location from the prism parser and set the necessary instance variables.

Like Net::HTTP.get, but writes the returned body to $stdout; returns nil.

Posts data to a host; returns a Net::HTTPResponse object.

Argument url must be a URI; argument data must be a hash:

_uri = uri.dup
_uri.path = '/posts'
data = {title: 'foo', body: 'bar', userId: 1}
res = Net::HTTP.post_form(_uri, data) # => #<Net::HTTPCreated 201 Created readbody=true>
puts res.body

Output:

{
  "title": "foo",
  "body": "bar",
  "userId": "1",
  "id": 101
}

Sets the write timeout, in seconds, for self to integer sec; the initial value is 60.

Argument sec must be a non-negative numeric value:

_uri = uri.dup
_uri.path = '/posts'
body = 'bar' * 200000
data = <<EOF
{"title": "foo", "body": "#{body}", "userId": "1"}
EOF
headers = {'content-type': 'application/json'}
http = Net::HTTP.new(hostname)
http.write_timeout # => 60
http.post(_uri.path, data, headers)
# => #<Net::HTTPCreated 201 Created readbody=true>
http.write_timeout = 0
http.post(_uri.path, data, headers) # Raises Net::WriteTimeout.

Sends a GET request to the server; forms the response into a Net::HTTPResponse object.

The request is based on the Net::HTTP::Get object created from string path and initial headers hash initheader.

With no block given, returns the response object:

http = Net::HTTP.new(hostname)
http.request_get('/todos') # => #<Net::HTTPOK 200 OK readbody=true>

With a block given, calls the block with the response object and returns the response object:

http.request_get('/todos') do |res|
  p res
end # => #<Net::HTTPOK 200 OK readbody=true>

Output:

#<Net::HTTPOK 200 OK readbody=false>

Sends a HEAD request to the server; returns an instance of a subclass of Net::HTTPResponse.

The request is based on the Net::HTTP::Head object created from string path and initial headers hash initheader.

http = Net::HTTP.new(hostname)
http.head('/todos/1') # => #<Net::HTTPOK 200 OK readbody=true>

Sends an HTTP request to the server; returns an instance of a subclass of Net::HTTPResponse.

The request is based on the Net::HTTPRequest object created from string path, string data, and initial headers hash header. That object is an instance of the subclass of Net::HTTPRequest, that corresponds to the given uppercase string name, which must be an HTTP request method or a WebDAV request method.

Examples:

http = Net::HTTP.new(hostname)
http.send_request('GET', '/todos/1')
# => #<Net::HTTPOK 200 OK readbody=true>
http.send_request('POST', '/todos', 'xyzzy')
# => #<Net::HTTPCreated 201 Created readbody=true>
