Ruby Programming Language

What is a Ruby file?

A Ruby (.rb) file is a source code file written in the Ruby programming language, a dynamic, object-oriented scripting language known for its simplicity and productivity. Ruby emphasizes programmer happiness and follows the principle of least surprise, meaning the language behaves in a way that minimizes confusion for experienced users. Ruby files contain classes, methods, and expressions that are interpreted at runtime, making development fast and interactive.

More Information

Ruby was created by Yukihiro "Matz" Matsumoto in Japan in the mid-1990s, with the first public release in 1995. Matz designed Ruby to be more powerful than Perl and more object-oriented than Python, combining functional programming with imperative programming in an elegant syntax. Ruby gained worldwide popularity, particularly after the release of Ruby on Rails web framework in 2004, which demonstrated Ruby's potential for rapid web application development.

Ruby's design philosophy prioritizes developer productivity and enjoyment over machine efficiency. The language features a pure object-oriented approach where everything is an object, including primitive data types. Ruby's flexible syntax allows for multiple ways to accomplish the same task, giving developers the freedom to write code that feels natural and expressive. The strong community and rich ecosystem of gems (libraries) have contributed to Ruby's continued relevance in modern software development.

Ruby Format

Ruby has an expressive and flexible syntax with minimal punctuation:

Basic Syntax

No semicolons - Line breaks separate statements
No braces - Uses end keyword to close blocks
Variable naming - snake_case convention
Method calls - Parentheses are optional
String interpolation - #{variable} within double quotes
Symbols - Immutable identifiers starting with colon

Key Features

Everything is an object - Even numbers and nil have methods
Duck typing - If it walks like a duck and quacks like a duck...
Blocks and iterators - Functional programming constructs
Mixins - Multiple inheritance through modules
Metaprogramming - Code that writes code
Dynamic typing - Types determined at runtime

Data Types and Structures

Numbers - Integer, Float, Rational, Complex
Strings - Mutable character sequences
Arrays - Ordered collections of objects
Hashes - Key-value pair collections
Symbols - Immutable identifiers
Regular expressions - Built-in pattern matching

Common Patterns

# Class definition
class Person
  attr_accessor :name, :age
  
  def initialize(name, age)
    @name = name
    @age = age
  end
  
  def greet
    "Hello, I'm #{@name} and I'm #{@age} years old"
  end
  
  def adult?
    @age >= 18
  end
end

# Creating and using objects
person = Person.new("Alice", 25)
puts person.greet

# Blocks and iterators
[1, 2, 3, 4, 5].each do |num|
  puts num * 2
end

# Hash example
user = {
  name: "Bob",
  email: "[email protected]",
  age: 30
}

# Method with block
def with_timing
  start_time = Time.now
  yield
  end_time = Time.now
  puts "Execution time: #{end_time - start_time} seconds"
end
