Copper – A minimal low-level programming language with OOP and generics

2026-10-30T19:09:33+00:00

Copper is a programming language that I use as a replacement to C. The main differences are:

Minimalism is the most important feature, the language is intended to be simple so that someone with limited brain power such as me could fully understand it. The syntax is simple, almost everything is explicit and most constructs are common.

A simple example beyond the pointless "hello world".

class Point
    attr x: Int
    attr y: Int

    def init(x: Int, y: Int)
        self.x = x
        self.y = y
    end

    def translate(dx: Int, dy: Int)
        self.x += dx
        self.y += dy
    end
end

func main: Int
    var pt: Point!
    pt.init(3, 5)
    pt.translate(1, 0)
    println("x = \a, y = \a", pt.x, pt.y)
    return 0
end

import "std"
