Results for: "Array"

Return a list of the local variable names defined where this NameError exception was raised.

Internal use only.

Returns an array of the names of class variables in mod. This includes the names of class variables in any included modules, unless the inherit parameter is set to false.

class One
  @@var1 = 1
end
class Two < One
  @@var2 = 2
end
One.class_variables          #=> [:@@var1]
Two.class_variables          #=> [:@@var2, :@@var1]
Two.class_variables(false)   #=> [:@@var2]

Returns the fractional part of the second.

DateTime.new(2001,2,3,4,5,6.5).sec_fraction       #=> (1/2)

Returns the fractional part of the second.

DateTime.new(2001,2,3,4,5,6.5).sec_fraction       #=> (1/2)

Duplicates self and resets its the day of calendar reform.

d = Date.new(1582,10,15)
d.new_start(Date::JULIAN)         #=> #<Date: 1582-10-05 ...>

This method is equivalent to d + n.

This method is equivalent to d - n.

This method is equivalent to d >> (n * 12)

This method is equivalent to d << (n * 12)

Calls the given block once for each character in ios, passing the character as an argument. The stream must be opened for reading or an IOError will be raised.

If no block is given, an enumerator is returned instead.

f = File.new("testfile")
f.each_char {|c| print c, ' ' }   #=> #<File:testfile>

This method is called when the parser found syntax error.

EXPERIMENTAL

Parses src and create S-exp tree. This method is mainly for developer use.

require 'ripper'
require 'pp'

pp Ripper.sexp_raw("def m(a) nil end")
  #=> [:program,
       [:stmts_add,
        [:stmts_new],
        [:def,
         [:@ident, "m", [1, 4]],
         [:paren, [:params, [[:@ident, "a", [1, 6]]], nil, nil, nil]],
         [:bodystmt,
          [:stmts_add, [:stmts_new], [:var_ref, [:@kw, "nil", [1, 9]]]],
          nil,
          nil,
          nil]]]]

See IO#each_char.

Scans the string until the pattern is matched. Advances the scan pointer if advance_pointer_p, otherwise not. Returns the matched string if return_string_p is true, otherwise returns the number of bytes advanced. This method does affect the match register.

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

Return the accept character set for all new CGI instances.

Set the accept character set for all new CGI instances.

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.

This method is a shortcut for converting a single line of a CSV String into an Array. Note that if line contains multiple rows, anything beyond the first row is ignored.

The options parameter can be anything CSV::new() understands.

Pre-compiles parsers and stores them by name for access during reads.

This method is used to turn a finished row into a CSV::Row. Header rows are also dealt with here, either by returning a CSV::Row with identical headers and fields (save that the fields do not go through the converters) or by reading past them to return a field row. Headers are also saved in @headers for use in future rows.

When nil, row is assumed to be a header row not based on an actual row of the stream.

Returns the encoding of the internal IO object or the default if the encoding cannot be determined.

Serialization support for the object returned by _getobj_.
