Results for: "Array"

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.

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

Returns a new hash with the results of running the block once for every key. This method does not change the values.

h = { a: 1, b: 2, c: 3 }
h.transform_keys {|k| k.to_s }  #=> { "a" => 1, "b" => 2, "c" => 3 }
h.transform_keys(&:to_s)        #=> { "a" => 1, "b" => 2, "c" => 3 }
h.transform_keys.with_index {|k, i| "#{k}.#{i}" }
                                #=> { "a.0" => 1, "b.1" => 2, "c.2" => 3 }

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

Invokes the given block once for each key in hsh, replacing it with the new key returned by the block, and then returns hsh. This method does not change the values.

h = { a: 1, b: 2, c: 3 }
h.transform_keys! {|k| k.to_s }  #=> { "a" => 1, "b" => 2, "c" => 3 }
h.transform_keys!(&:to_sym)      #=> { a: 1, b: 2, c: 3 }
h.transform_keys!.with_index {|k, i| "#{k}.#{i}" }
                                 #=> { "a.0" => 1, "b.1" => 2, "c.2" => 3 }

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

Returns a new hash with the results of running the block once for every value. This method does not change the keys.

h = { a: 1, b: 2, c: 3 }
h.transform_values {|v| v * v + 1 }  #=> { a: 2, b: 5, c: 10 }
h.transform_values(&:to_s)           #=> { a: "1", b: "2", c: "3" }
h.transform_values.with_index {|v, i| "#{v}.#{i}" }
                                     #=> { a: "1.0", b: "2.1", c: "3.2" }

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

Invokes the given block once for each value in hsh, replacing it with the new value returned by the block, and then returns hsh. This method does not change the keys.

h = { a: 1, b: 2, c: 3 }
h.transform_values! {|v| v * v + 1 }  #=> { a: 2, b: 5, c: 10 }
h.transform_values!(&:to_s)           #=> { a: "2", b: "5", c: "10" }
h.transform_values!.with_index {|v, i| "#{v}.#{i}" }
                                      #=> { a: "2.0", b: "5.1", c: "10.2" }

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

Iterates over each character of each file in ARGF.

This method allows you to treat the files supplied on the command line as a single file consisting of the concatenation of each named file. After the last character of the first file has been returned, the first character of the second file is returned. The ARGF.filename method can be used to determine the name of the file in which the current character appears.

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

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.

The encoded :quote_char used in parsing and writing. See CSV::new for details.

Returns the encoding of the internal IO object.

Serialization support for the object returned by _getobj_.

Reinitializes delegation from a serialized object.

Can be used to set eoutvar as described in ERB::new. It’s probably easier to just use the constructor though, since calling this method requires the setup of an ERB compiler object.

Set an error (a protected method).

Return the appropriate error message in POSIX-defined format. If no error has occurred, returns nil.

Returns a string for DNS reverse lookup compatible with RFC3172.

Creates a Range object for the network address.
