Advent of Code for 2023 - https://adventofcode.com/2023

Creating a new date executable

Per day, remember to:

export day=day25
cargo new $day
cp day01/Makefile $day/
cp -r template/* $day/
find $day -type f -exec sed -i "s/template/$day/g" {} +
make format
find . -iname "template.day" -delete
git add $day
git commit -m "$day: Added template"

By convention for this repo, so I can ignore it, all programs will be called <foldername>.day eg day01.day.

To format code, call:

make format

Dependencies

To make a new lib:

cargo new --lib foo

Then you can refer to that lib in the Cargo.toml:

[dependencies.my_lib]
path = "../my_lib"

And in the code use

extern crate my_lib;

Note: Libs use a slightly different Makefile (no copy)

Lib list

• filelib - A library for common file operations needed in advent of code. Most notably load_as_ints, which is used to load input that is just numbers per line.
• mathlib - Math operations and functions I might need later.
• gridlib - Represents a grid, a common pattern.
