IntcodeComputer

An Elixir implementation of the Intcode Computer from Advent of Code 2019.

Description

IntcodeComputer is an Elixir library that simulates the Intcode Computer, a virtual machine introduced in the Advent of Code 2019 programming puzzles. This implementation supports all operations from Days 2, 5, 9, and 11, including:

• Basic arithmetic (addition, multiplication)
• Input/Output operations
• Conditional jumps
• Comparisons
• Relative mode addressing
• Dynamic memory expansion

Installation

If available in Hex, the package can be installed by adding intcode_computer to your list of dependencies in mix.exs:

def deps do
  [
    {:intcode_computer, "~> 0.1.0"}
  ]
end

Usage

CLI

This package comes with a custom mix task to run the computer with a given program:

mix intcode.run "3,0,4,0,99"

Lib

Here's a basic example of how to use the IntcodeComputer:

alias IntcodeComputer.Computer

Computer.new("3,0,4,0,99")
  |> Computer.run()

This will create a new Intcode Computer, load the program, and run it. Input and output are provided via stdin/stdout.

Features

• Supports all Intcode operations from Advent of Code 2019 (Days 2, 5, 9, and 11)
• Customizable input and output handling via callback functions
• Expandable memory
• Relative mode addressing

Testing

To run the tests:

mix test
