Advent of Code for 2021 - https://adventofcode.com/2021

Creating a new date executable

Per day, remember to:

export day=day25
cargo new $day
cp day01/Makefile $day/
touch $day/README.md
touch $day/input
touch $day/src/lib.rs
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 - File input/output helper methods to do with basic types (eg, not types in other libraries)
• submarinelib - Provides structs to represent a Submarine, where it is, its movement, etc.
• ivec3 - a vector x,y,z for math operations.
• boardlib - Handles a 2 dimensional board and coordinate system that can be used with various types.
