Convert path string to a class
Emit a map. The coder will be yielded to the block.
Emit a map with value
Returns a Psych::Parser::Mark object that contains line, column, and index information.
Get the indentation level.
Set the indentation level to level. The level must be less than 10 and greater than 1.
Returns the exit status of the child for which PTY#check raised this exception
The scanner’s state of the current token. This value is the bitwise OR of zero or more of the Ripper::EXPR_* constants.
returns the cmsg data as a string.
p Socket::AncillaryData.new(:INET6, :IPV6, :PKTINFO, "").data #=> ""
Returns the netmask address of ifaddr. nil is returned if netmask is not available in ifaddr.
returns the socket option data as a string.
p Socket::Option.new(:INET6, :IPV6, :RECVPKTINFO, [1].pack("i!")).data #=> "\x01\x00\x00\x00"
— 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
Same as IO.
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.
