Class: Binding (Ruby 2.1.5)
Objects of class Binding encapsulate the execution context at some particular place in the code and retain this context for future use. The variables, methods, value of self, and possibly an iterator block that can be accessed in this context are all retained. Binding objects can be created using Kernel#binding, and are made available to the callback of Kernel#set_trace_func. These binding objects
Class: Regexp (Ruby 1.9.3)
Extended maintenance of Ruby 1.9.3 ended on February 23, 2015. Read more A Regexp holds a regular expression, used to match a pattern against strings. Regexps are created using the /.../ and %r{...} literals, and by the Regexp::new constructor. Regular expressions (regexps) are patterns which describe the contents of a string. They're used for testing whether a string contains a given pattern, or
Class: Regexp (Ruby 2.1.4)
Support for the Ruby 2.1 series ended on March 31 2017. See here for details. A Regexp holds a regular expression, used to match a pattern against strings. Regexps are created using the /.../ and %r{...} literals, and by the Regexp::new constructor. Regular expressions (regexps) are patterns which describe the contents of a string. They're used for testing whether a string contains a given pattern
Class: Hash (Ruby 2.1.4)
A Hash is a dictionary-like collection of unique keys and their values. Also called associative arrays, they are similar to Arrays, but where an Array uses integers as its index, a Hash allows you to use any object type. Hashes enumerate their values in the order that the corresponding keys were inserted. A Hash can be easily created by using its implicit form: grades = { "Jane Doe" => 10, "Jim Do

Class: CSV (Ruby 2.0.0)
This class provides a complete interface to CSV files and data. It offers tools to enable you to read and write to and from Strings or IO objects, as needed. Reading¶ ↑ From a File¶ ↑ A Line at a Time¶ ↑ CSV.foreach("path/to/file.csv") do |row| # use row here... end All at Once¶ ↑ arr_of_arrs = CSV.read("path/to/file.csv") From a String¶ ↑ A Line at a Time¶ ↑ CSV.parse("CSV,data,String") do |row|
Class: IO (Ruby 2.1.3)
The IO class is the basis for all input and output in Ruby. An I/O stream may be duplexed (that is, bidirectional), and so may use more than one native operating system stream. Many of the examples in this section use the File class, the only standard subclass of IO. The two classes are closely associated. Like the File class, the Socket library subclasses from IO (such as TCPSocket or UDPSocket).
