Results for: "Array.new"

Returns the remote address as an array which contains address_family and unix_path.

Example

serv = UNIXServer.new("/tmp/sock")
c = UNIXSocket.new("/tmp/sock")
p c.peeraddr #=> ["AF_UNIX", "/tmp/sock"]

Returns the current line number in strio. The stringio must be opened for reading. lineno counts the number of times gets is called, rather than the number of newlines encountered. The two values will differ if gets is called with a separator other than newline. See also the $. variable.

Manually sets the current line number to the given value. $. is updated only on the next read.

Positions strio to the beginning of input, resetting lineno to zero.

This is a deprecated alias for each_line.

This is a deprecated alias for each_char.

See IO#readlines.

Equivalent to terminate. This method is obsolete; use terminate instead.

Returns the character position of the scan pointer. In the ‘reset’ position, this value is zero. In the ‘terminated’ position (i.e. the string is exhausted), this value is the size of the string.

In short, it’s a 0-based index into the string.

s = StringScanner.new("abcädeföghi")
s.charpos           # -> 0
s.scan_until(/ä/)   # -> "abcä"
s.pos               # -> 5
s.charpos           # -> 4

Returns running OLE Automation object or WIN32OLE object from moniker. 1st argument should be OLE program id or class id or moniker.

WIN32OLE.connect('Excel.Application') # => WIN32OLE object which represents running Excel.

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

Removes all key-value pairs from hsh.

h = { "a" => 100, "b" => 200 }   #=> {"a"=>100, "b"=>200}
h.clear                          #=> {}

Searches through the hash comparing obj with the value using ==. Returns the first key-value pair (two-element array) that matches. See also Array#rassoc.

a = {1=> "one", 2 => "two", 3 => "three", "ii" => "two"}
a.rassoc("two")    #=> [2, "two"]
a.rassoc("four")   #=> nil

Removes every environment variable.

Returns an Array of the name and value of the environment variable with value or nil if the value cannot be found.

Parse an HTTP query string into a hash of key=>value pairs.

params = CGI::parse("query_string")
  # {"name1" => ["value1", "value2", ...],
  #  "name2" => ["value1", "value2", ...], ... }

This method can be used to easily parse CSV out of a String. You may either provide a block which will be called with each row of the String in turn, or just use the returned Array of Arrays (when no block is given).

You pass your str to read from, and an optional options Hash containing anything CSV::new() understands.

Alias for CSV::read().

Rewinds the underlying IO object and resets CSV’s lineno() counter.

Returns the display expression list
