Returns array of WIN32OLE_TYPE objects defined by the typelib type library. This method will be OBSOLETE. Use WIN32OLE_TYPELIB.new(typelib).ole_classes instead.
Returns library name. If the method fails to access library name, WIN32OLERuntimeError is raised.
tlib = WIN32OLE_TYPELIB.new('Microsoft Excel 9.0 Object Library') tlib.library_name # => Excel
Returns the type library file path.
tlib = WIN32OLE_TYPELIB.new('Microsoft Excel 9.0 Object Library') classes = tlib.ole_types.collect{|k| k.name} # -> ['AddIn', 'AddIns' ...]
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
Calls block once for each key in hsh, passing the key-value pair as parameters.
If no block is given, an enumerator is returned instead.
h = { "a" => 100, "b" => 200 } h.each {|key, value| puts "#{key} is #{value}" }
produces:
a is 100 b is 200
Yields each environment variable name and value.
If no block is given an Enumerator is returned.
Create an HTTP header block as a string.
Includes the empty line that ends the header block.
content_type_string
If this form is used, this string is the Content-Type
headers_hash
A Hash of header values. The following header keys are recognized:
The Content-Type header. Defaults to “text/html”
The charset of the body, appended to the Content-Type header.
A boolean value. If true, prepend protocol string and status code, and date; and sets default values for “server” and “connection” if not explicitly set.
The HTTP status code as a String, returned as the Status header. The values are:
200 OK
206 Partial Content
300 Multiple Choices
301 Moved Permanently
302 Found
304 Not Modified
400 Bad Request
401 Authorization Required
403 Forbidden
404 Not Found
405 Method Not Allowed
406 Not Acceptable
411 Length Required
412 Precondition Failed
500 Internal Server Error
501 Method Not Implemented
502 Bad Gateway
506 Variant Also Negotiates
The server software, returned as the Server header.
The connection type, returned as the Connection header (for instance, “close”.
The length of the content that will be sent, returned as the Content-Length header.
The language of the content, returned as the Content-Language header.
The time on which the current content expires, as a Time object, returned as the Expires header.
A cookie or cookies, returned as one or more Set-Cookie headers. The value can be the literal string of the cookie; a CGI::Cookie object; an Array of literal cookie strings or Cookie objects; or a hash all of whose values are literal cookie strings or Cookie objects.
These cookies are in addition to the cookies held in the @output_cookies field.
Other headers can also be set; they are appended as key: value.
Examples:
http_header
# Content-Type: text/html
http_header("text/plain")
# Content-Type: text/plain
http_header("nph" => true,
"status" => "OK", # == "200 OK"
# "status" => "200 GOOD",
"server" => ENV['SERVER_SOFTWARE'],
"connection" => "close",
"type" => "text/html",
"charset" => "iso-2022-jp",
# Content-Type: text/html; charset=iso-2022-jp
"length" => 103,
"language" => "ja",
"expires" => Time.now + 30,
"cookie" => [cookie1, cookie2],
"my_header1" => "my_value"
"my_header2" => "my_value")
This method does not perform charset conversion.
This method is a shortcut for converting a single row (Array) into a CSV String.
The options parameter can be anything CSV::new() understands. This method understands an additional :encoding parameter to set the base Encoding for the output. This method will try to guess your Encoding from the first non-nil field in row, if possible, but you may need to use this parameter as a backup plan.
The :row_sep option defaults to $INPUT_RECORD_SEPARATOR ($/) when calling this method.
Returns true if the next row read will be a header row.
Used to filter unwanted trace output
Example which only outputs lines of code executed within the Kernel class:
Tracer.add_filter do |event, file, line, id, binding, klass, *rest| "Kernel" == klass.to_s end
Creates a new compiler for ERB. See ERB::Compiler.new for details
Returns a new binding each time near TOPLEVEL_BINDING for runs that do not specify a binding.
Return the appropriate error message in POSIX-defined format. If no error has occurred, returns nil.
Returns true if the ipaddr is an IPv4-compatible IPv6 address.
Returns a new ipaddr built by converting the native IPv4 address into an IPv4-compatible IPv6 address.
Set date-time format.
datetime_format
A string suitable for passing to strftime.
Returns the date format being used. See datetime_format=
Returns the submatrix obtained by deleting the specified row and column.
Matrix.diagonal(9, 5, -3, 4).first_minor(1, 2)
=> 9 0 0
0 0 0
0 0 4
Returns an array of the row vectors of the matrix. See Vector.
Returns an array of the column vectors of the matrix. See Vector.
Returns the inner product of this vector with the other.
Vector[4,7].inner_product Vector[10,1] => 47
