OOlib is currently work in progress🔥

🗺Overview

OOlib is a nimble package for object oriented programming.

📜Usage

class

import oolib

class Person:
  var
    name: string
    age = 0

  proc greet =
    echo "hello, I'm ", self.name

let steve = Person.new(name = "Steve")
let tony = Person.new(name = "Tony", age = 30)

steve.greet()
tony.greet()

protocol

import oolib

protocol Readable:
  var text: string

protocol Writable:
  var text: string
  proc `text=`(value: string)

protocol Product:
  var price: int

protocol pub Writer:
  proc write(text: string)

class Book impl (Readable, Product):
  var
    text: string = ""
    price: int

class Diary impl (Readable, Writable, Product):
  var text {.initial.}: string = ""
  var price: int
  proc `text=`(value: string) =
    self.text = value

class HTMLWriter impl Writer:
  var writable: Writable
  proc write(text: string) =
    self.writable.text = text

✨Features

• class
  • Automatic generation of constructor
  • self inserted in procedures
  • All routines (e.g., method, converter, template) are supported, excluding macro
• protocol
  • A Kotlin-like interface
  • Defining setter/getter
• construct
  • An easy way to declare a class without class, only supporting normal class
• protocoled
  • The same as construct, but for interface
• isInstanceOf for checking if a variable is an instance of a class or can be converted into a protocol

💭Planning

• struct from Swift
• dataclass from Kotlin
• sealed class from Kotlin
