AocRb

This gem provides a simple way to create a project for solving Advent of Code puzzles.

It also provides some handy tools to automate your interactions with the Advent of Code website.

If you want more help with your puzzles (use with care ... it'll take the fun out of doing it yourself) then take a look at aoc_rb_helpers.

First of all, install the gem:

$ gem install aoc_rb

Next, generate your Advent of Code project:

$ aoc new my-project-name

This will generate a new project with the given name. After this you should be ready to go!

$ cd my-project-name
$ aoc

Before running any commands, you must set up your AOC_COOKIE environment variable:

$ cp .env-template .env

You'll need to log in to the Advent of Code website and then grab a copy of your session key from your cookies. In Chrome you can do this by opening the Developer Tools window (⌥ ⌘ I on Mac) when browsing the Advent of Code website. Within the Application tab, expand Cookies under Storage in the side menu and select https://adventofcode.com. This will then show you all of the cookies set by the website. You need to select the session cookie and copy the value.

Now edit the new .env file, so that it looks like the following, replacing ABCDE12345 with the session key you just copied:

AOC_COOKIE=ABCDE12345

You're now able to run all the aoc commands provided by this gem.

You'll see you have a few options when running the aoc command within your project. Running aoc help will show you all of your options:

$ aoc help
Commands:
  aoc exec            # executes and optionally submits the puzzle for today, or the specified date
  aoc help [COMMAND]  # Describe available commands or one specific command
  aoc output          # outputs results from your solution for the given day
  aoc prep            # preps everything you need for a new puzzle
  aoc spec            # runs tests for today, or the specified date
  aoc version         # prints the current installed version of AocRb

If you want to see you options for a given command:

$ aoc help prep
Usage:
  aoc prep

Options:
  -y, [--year=N]  
  -d, [--day=N]   

Running aoc prep will set everything up for a new daily puzzle. It defaults to the puzzle for today, but you can work with older puzzles by passing the year and day:

$ aoc prep 2017 12

This will generate a challenges/2017/12 folder with an input.txt file (your puzzle input), a part_1.md file with the instructions for part 1, and a solution.rb file for you to use when implementing your solution.

In spec/2017/12 there will be a solution_spec.rb which you can use to write tests for your solution. It's a good idea to use the examples provided in the part_1.md to test your solution!

When you've got a working solution you can see what it generates by running:

$ aoc exec

Which runs todays solution. For previous days, just like with prep, you can provide a date:

$ aoc exec 2017 12

If you're happy with the output, you can respond to the prompt and aoc will submit your answer for you. If you're successful with part 1, it will automatically download the instructions for part 2 for you.

Rinse & repeat!
