AocHelper

Helper for your Advent of Code days.

Install

mix archive.install github rockneurotiko/aoc_helper

From now on, you can use the mix task mix aoc.new.

Usage

Create base code and try to download data:

mix aoc.new --year 2020 --day 1

Year and day are optional, if not provided it will use the current date. If you are doing the AoC day by day, just executing mix aoc.new will create it for the current day.

This command will create a module named <YourPackage>.Aoc<year>.Day<day>.Solve in the path lib/<your_package>/<year>/<day>/solve.ex

You have to implement star1/1 and star2/2, and from the iex console you can call <...>.Solve.solve(), it will read the input file in the day directory and call star1 and star2.

You can implement the parse_line/1 to custom parsing the input lines.

You can see an example of the files generated here

Data downloading

The mix task will try to use aocd to download the data for the specified day.

I recommend installing and configuring the command in order to simplify your AoC daily flow even more.

The simplified installation and config is:

pip install advent-of-code-data

Go to https://adventofcode.com/ and login, retrieve the cookie session value and save it in ~/.config/aocd/token

Example generated files:

• solve.ex
• input
