Returns the destination address of ifaddr. nil is returned if the flags doesn’t have IFF_POINTOPOINT.
— Registry.create(key, subkey, desired = KEY_ALL_ACCESS, opt = REG_OPTION_RESERVED)
— Registry.create(key, subkey, desired = KEY_ALL_ACCESS, opt = REG_OPTION_RESERVED) { |reg| … }
Create or open the registry key subkey under key. You can use predefined key HKEY_* (see Constants)
If subkey is already exists, key is opened and Registry#created? method will return false.
If block is given, the key is closed automatically.
Returns if key is created ((newly)). (see Registry.create) – basically you call create then when you call created? on the instance returned it will tell if it was successful or not
Same as Win32::Registry.create (self, subkey, desired, opt)
Returns the type library file path.
tlib = WIN32OLE::TypeLib.new('Microsoft Excel 9.0 Object Library') puts tlib.path #-> 'C:\...\EXCEL9.OLB'
Compresses the given string. Valid values of level are Zlib::NO_COMPRESSION, Zlib::BEST_SPEED, Zlib::BEST_COMPRESSION, Zlib::DEFAULT_COMPRESSION, or an integer from 0 to 9.
This method is almost equivalent to the following code:
def deflate(string, level) z = Zlib::Deflate.new(level) dst = z.deflate(string, Zlib::FINISH) z.close dst end
See also Zlib.inflate
Inputs string into the deflate stream and returns the output from the stream. On calling this method, both the input and the output buffers of the stream are flushed. If string is nil, this method finishes the stream, just like Zlib::ZStream#finish.
If a block is given consecutive deflated chunks from the string are yielded to the block and nil is returned.
The flush parameter specifies the flush mode. The following constants may be used:
The default
Flushes the output to a byte boundary
SYNC_FLUSH + resets the compression state
Pending input is processed, pending output is flushed.
See the constants for further description.
Decompresses string. Raises a Zlib::NeedDict exception if a preset dictionary is needed for decompression.
This method is almost equivalent to the following code:
def inflate(string) zstream = Zlib::Inflate.new buf = zstream.inflate(string) zstream.finish zstream.close buf end
See also Zlib.deflate
Inputs deflate_string into the inflate stream and returns the output from the stream. Calling this method, both the input and the output buffer of the stream are flushed. If string is nil, this method finishes the stream, just like Zlib::ZStream#finish.
If a block is given consecutive inflated chunks from the deflate_string are yielded to the block and nil is returned.
If a :buffer keyword argument is given and not nil:
The :buffer keyword should be a String, and will used as the output buffer. Using this option can reuse the memory required during inflation.
When not passing a block, the return value will be the same object as the :buffer keyword argument.
When passing a block, the yielded chunks will be the same value as the :buffer keyword argument.
Raises a Zlib::NeedDict exception if a preset dictionary is needed to decompress. Set the dictionary by Zlib::Inflate#set_dictionary and then call this method again with an empty string to flush the stream:
inflater = Zlib::Inflate.new begin out = inflater.inflate compressed rescue Zlib::NeedDict # ensure the dictionary matches the stream's required dictionary raise unless inflater.adler == Zlib.adler32(dictionary) inflater.set_dictionary dictionary inflater.inflate '' end # ... inflater.close
See also Zlib::Inflate.new
Decompresses all gzip data in the io, handling multiple gzip streams until the end of the io. There should not be any non-gzip data after the gzip streams.
If a block is given, it is yielded strings of uncompressed data, and the method returns nil. If a block is not given, the method returns the concatenation of all uncompressed data in all gzip streams.
Returns the last access time for this file as an object of class Time.
File.stat("testfile").atime #=> Wed Dec 31 18:00:00 CST 1969
Returns true if stat is readable by the effective user id of this process.
File.stat("testfile").readable? #=> true
Returns true if stat is writable by the effective user id of this process.
File.stat("testfile").writable? #=> true
Returns true if stat is executable or if the operating system doesn’t distinguish executable files from nonexecutable files. The tests are made using the effective owner of the process.
File.stat("testfile").executable? #=> false
If the buffer is private, meaning modifications to the buffer will not be replicated to the underlying file mapping.
# Create a test file: File.write('test.txt', 'test') # Create a private mapping from the given file. Note that the file here # is opened in read-only mode, but it doesn't matter due to the private # mapping: buffer = IO::Buffer.map(File.open('test.txt'), nil, 0, IO::Buffer::PRIVATE) # => #<IO::Buffer 0x00007fce63f11000+4 MAPPED PRIVATE> # Write to the buffer (invoking CoW of the underlying file buffer): buffer.set_string('b', 0) # => 1 # The file itself is not modified: File.read('test.txt') # => "test"
Returns the path of this instruction sequence.
<compiled> if the iseq was evaluated from a string.
For example, using irb:
iseq = RubyVM::InstructionSequence.compile('num = 1 + 2') #=> <RubyVM::InstructionSequence:<compiled>@<compiled>> iseq.path #=> "<compiled>"
Using ::compile_file:
# /tmp/method.rb
def hello
puts "hello, world"
end
# in irb
> iseq = RubyVM::InstructionSequence.compile_file('/tmp/method.rb')
> iseq.path #=> /tmp/method.rb
Returns the contents of this Tms object as a formatted string, according to a format string like that passed to Kernel.format. In addition, format accepts the following extensions:
%u
Replaced by the user CPU time, as reported by Tms#utime.
%y
Replaced by the system CPU time, as reported by stime (Mnemonic: y of “s*y*stem”)
%U
Replaced by the children’s user CPU time, as reported by Tms#cutime
%Y
Replaced by the children’s system CPU time, as reported by Tms#cstime
%t
Replaced by the total CPU time, as reported by Tms#total
%r
Replaced by the elapsed real time, as reported by Tms#real
%n
Replaced by the label string, as reported by Tms#label (Mnemonic: n of “*n*ame”)
If format is not given, FORMAT is used as default value, detailing the user, system and real elapsed time.

Creates a new Net::HTTP object, http, via Net::HTTP.new:
For arguments address and port, see Net::HTTP.new.
For proxy-defining arguments p_addr through p_pass, see Proxy Server.
For argument opts, see below.
With no block given:
Calls http.start with no block (see start), which opens a TCP connection and HTTP session.
Returns http.
The caller should call finish to close the session:
http = Net::HTTP.start(hostname) http.started? # => true http.finish http.started? # => false
With a block given:
Calls http.start with the block (see start), which:
Opens a TCP connection and HTTP session.
Calls the block, which may make any number of requests to the host.
Closes the HTTP session and TCP connection on block exit.
Returns the block’s value object.
Returns object.
Example:
hostname = 'jsonplaceholder.typicode.com' Net::HTTP.start(hostname) do |http| puts http.get('/todos/1').body puts http.get('/todos/2').body end
Output:
{
"userId": 1,
"id": 1,
"title": "delectus aut autem",
"completed": false
}
{
"userId": 1,
"id": 2,
"title": "quis ut nam facilis et officia qui",
"completed": false
}
If the last argument given is a hash, it is the opts hash, where each key is a method or accessor to be called, and its value is the value to be set.
The keys may include:
Note: If port is nil and opts[:use_ssl] is a truthy value, the value passed to new is Net::HTTP.https_default_port, not port.
Returns true if the HTTP session has been started:
http = Net::HTTP.new(hostname) http.started? # => false http.start http.started? # => true http.finish # => nil http.started? # => false Net::HTTP.start(hostname) do |http| http.started? end # => true http.started? # => false
Starts an HTTP session.
Without a block, returns self:
http = Net::HTTP.new(hostname) # => #<Net::HTTP jsonplaceholder.typicode.com:80 open=false> http.start # => #<Net::HTTP jsonplaceholder.typicode.com:80 open=true> http.started? # => true http.finish
With a block, calls the block with self, finishes the session when the block exits, and returns the block’s value:
http.start do |http| http end # => #<Net::HTTP jsonplaceholder.typicode.com:80 open=false> http.started? # => false
Sends a PATCH request to the server; returns an instance of a subclass of Net::HTTPResponse.
The request is based on the Net::HTTP::Patch object created from string path, string data, and initial headers hash initheader.
With a block given, calls the block with the response body:
data = '{"userId": 1, "id": 1, "title": "delectus aut autem", "completed": false}' http = Net::HTTP.new(hostname) http.patch('/todos/1', data) do |res| p res end # => #<Net::HTTPOK 200 OK readbody=true>
Output:
"{\n \"userId\": 1,\n \"id\": 1,\n \"title\": \"delectus aut autem\",\n \"completed\": false,\n \"{\\\"userId\\\": 1, \\\"id\\\": 1, \\\"title\\\": \\\"delectus aut autem\\\", \\\"completed\\\": false}\": \"\"\n}"
With no block given, simply returns the response object:
http.patch('/todos/1', data) # => #<Net::HTTPCreated 201 Created readbody=true>
Sends a PROPPATCH request to the server; returns an instance of a subclass of Net::HTTPResponse.
The request is based on the Net::HTTP::Proppatch object created from string path, string body, and initial headers hash initheader.
data = '{"userId": 1, "id": 1, "title": "delectus aut autem", "completed": false}' http = Net::HTTP.new(hostname) http.proppatch('/todos/1', data)
Returns the path from an FTP URI.
RFC 1738 specifically states that the path for an FTP URI does not include the / which separates the URI path from the URI host. Example:
ftp://ftp.example.com/pub/ruby
The above URI indicates that the client should connect to ftp.example.com then cd to pub/ruby from the initial login directory.
If you want to cd to an absolute directory, you must include an escaped / (%2F) in the path. Example:
ftp://ftp.example.com/%2Fpub/ruby
This method will then return “/pub/ruby”.
Completion for hash key.
