Advent of Babashka
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}
Generating stub for new day
To generate a stub for a new day, run:
$ bb new-day --year 22 --day 2
The --year currently defaults to 22.
