A project for doing Advent of Code using babashka and nbb.

To install babashka, check here. It is recommended to use version 1.0.167 or higher. To install nbb: npm install -g nbb@latest. Nbb 1.1.151 or higher is required.

The first puzzle is in src/aoc22/day01.cljc. You can execute part 1 in both bb and nbb using:

$ bb -x aoc22.day01/part-1 [...args]
$ nbb -x aoc22.day01/part-1 [...args]

Each solution can take parameters from the command line if necessary. Arguments are parsed using babashka.cli:

$ bb -x clojure.core/prn --flag --option 1
{:flag true, :option 1}

You can also use Clojure JVM with the same argument parsing:

clj -M:cli clojure.core/prn --flag --option 1
{:flag true, :option 1}

To generate a stub for a new day, run:

$ bb new-day --year 22 --day 2

The --year currently defaults to 22.

To download your puzzle input from the Advent of Code website automatically, set the AOC_SESSION environment variable to your Advent of Code session cookie. You can find this by going to your browser's developer console.

You can also just download your puzzle input manually.

To install babashka, run

sudo bash < <(curl -s https://raw.githubusercontent.com/babashka/babashka/master/install)

To install nbb, run:

npm install -g nbb@latest

If you want to install nbb locally in the project, run npm install nbb@latest and use node_modules/.bin/nbb instead run nbb (this starts faster than npx nbb).
