Logs a message at the warn (syslog notice) log level, or logs the message returned from the block.
Returns array of WIN32OLE_VARIABLE objects which represent variables defined in OLE class.
tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'XlSheetType') vars = tobj.variables vars.each do |v| puts "#{v.name} = #{v.value}" end The result of above sample script is follows: xlChart = -4109 xlDialogSheet = -4116 xlExcel4IntlMacroSheet = 4 xlExcel4MacroSheet = 3 xlWorksheet = -4167
Returns the number which represents variable kind.
tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'XlSheetType')
variables = tobj.variables
variables.each do |variable|
puts "#{variable.name} #{variable.varkind}"
end
The result of above script is following:
xlChart 2
xlDialogSheet 2
xlExcel4IntlMacroSheet 2
xlExcel4MacroSheet 2
xlWorksheet 2
Returns OLE variant type.
obj = WIN32OLE_VARIANT.new("string") obj.vartype # => WIN32OLE::VARIANT::VT_BSTR
Creates a GzipReader or GzipWriter associated with io, passing in any necessary extra options, and executes the block with the newly created object just like File.open.
The GzipFile object will be closed automatically after executing the block. If you want to keep the associated IO object open, you may call Zlib::GzipFile#finish method in the block.
Reads at most maxlen bytes from the gziped stream but it blocks only if gzipreader has no data immediately available. If the optional outbuf argument is present, it must reference a String, which will receive the data. It raises EOFError on end of file.
See Zlib::GzipReader documentation for a description.
Returns true if the file is a character device, false if it isn’t or if the operating system doesn’t support this feature.
File.stat("/dev/tty").chardev? #=> true
Transfers ownership to a new buffer, deallocating the current one.
Example:
buffer = IO::Buffer.new('test') other = buffer.transfer other # => # #<IO::Buffer 0x00007f136a15f7b0+4 SLICE> # 0x00000000 74 65 73 74 test buffer # => # #<IO::Buffer 0x0000000000000000+0 NULL> buffer.null? # => true
If the buffer is shared, meaning it references memory that can be shared with other processes (and thus might change without being modified locally).
Fill buffer with value, starting with offset and going for length bytes.
buffer = IO::Buffer.for('test') # => # <IO::Buffer 0x00007fca40087c38+4 SLICE> # 0x00000000 74 65 73 74 test buffer.clear # => # <IO::Buffer 0x00007fca40087c38+4 SLICE> # 0x00000000 00 00 00 00 .... buf.clear(1) # fill with 1 # => # <IO::Buffer 0x00007fca40087c38+4 SLICE> # 0x00000000 01 01 01 01 .... buffer.clear(2, 1, 2) # fill with 2, starting from offset 1, for 2 bytes # => # <IO::Buffer 0x00007fca40087c38+4 SLICE> # 0x00000000 01 02 02 01 .... buffer.clear(2, 1) # fill with 2, starting from offset 1 # => # <IO::Buffer 0x00007fca40087c38+4 SLICE> # 0x00000000 01 02 02 02 ....
Parse a raw cookie string into a hash of cookie-name=>Cookie pairs.
cookies = CGI::Cookie.parse("raw_cookie_string") # { "name1" => cookie1, "name2" => cookie2, ... }
A set of tasks to prepare the file in order to parse it
Creates a new Net::HTTP object, http, via Net::HTTP.new:
Net::HTTP.new(address, port, p_addr, p_port, p_user, p_pass)
For arguments hostname through p_pass, see Net::HTTP.new.
For argument opts, see below.
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.
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:
