Installation and Usage

Make sure you have Julia 1.5 or newer installed on your system.

Installation

Start Julia and enter the package REPL by typing ]. Create a new environment:

(@v1.5) pkg> activate aoc

Install AdventOfCode2021.jl:

(aoc) pkg> add https://github.com/goggle/AdventOfCode2021.jl

Go back to the Julia REPL by pushing the backspace button.

Usage

First, activate the package:

julia> using AdventOfCode2021

Each puzzle can now be run with dayXY():

julia> day01()
2-element Vector{Int64}:
 1527
 1575

This will use my personal input. If you want to use another input, provide it to the dayXY method as a string. You can also use the readInput method to read your input from a text file:

julia> input = readInput("/path/to/input.txt")

julia> AdventOfCode2021.Day01.day01(input)
2-element Vector{Int64}:
 1527
 1575
