# OOP
[](https://travis-ci.org/wojtekmach/oop)
Are you tired of all of that modules, processes and functions nonsense? Do you want to just use classes, objects and methods? If so, use OOP [1] library in Elixir [2]!
## Demo
[](https://www.youtube.com/watch?v=5EtV2JUU0Z4)
## Example
```elixir
import OOP
class Person do
var :name
def say_hello_to(who) do
what = "Hello #{who.name}"
IO.puts("#{this.name}: #{what}")
end
end
joe = Person.new(name: "Joe")
mike = Person.new(name: "Mike")
robert = Person.new(name: "Robert")
joe.say_hello_to(mike) # Joe: Hello Mike
mike.say_hello_to(joe) # Mike: Hello Joe
mike.say_hello_to(robert) # Mike: Hello Robert
robert.say_hello_to(mike) # Robert: Hello Mike
joe.set_name("Hipster Joe")
joe.name # => Hipster Joe
```
An OOP library wouldn't be complete without inheritance:
```elixir
class Animal do
var :name
end
class Dog < Animal do
var :breed
end
snuffles = Dog.new(name: "Snuffles", breed: "Shih Tzu")
snuffles.name # => "Snuffles"
snuffles.breed # => "Shih Tzu"
```
... or multiple inheritance:
```elixir
class Human do
var :name
end
class Horse do
var :horseshoes_on?
end
class Centaur < [Human, Horse] do
end
john = Centaur.new(name: "John", horseshoes_on?: true)
john.name # => "John"
john.horseshoes_on? # => true
```
See more usage in the [test suite](test/oop_test.exs).
## Installation
Add `oop` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[{:oop, "~> 0.1.0"}]
end
```
[1] According to Alan Kay, the inventor of OOP, "objects" is the lesser idea; the big idea is "messaging". In that sense, I can't agree more with Joe Armstrong's quote that Erlang is "possibly the only object-oriented language".
[2] Please don't. You've been warned.
