AoC 2024

Advent of code 2024 solutions are in the ./2024 directory.

Solutions are in Go, Lua, Zig, and JavaScript (via NodeJS).

Go

Prerequisites

• Go @ 1.23.1

Running the Code

Run via:

go run src/main.go

Run and watch for changes:

make watch-go

Lua

Prerequisites

• Lua @ 5.4.7
• Luarocks

On MacOS:

brew install luarocks

Getting Started

Run the following to install dependencies:

luarocks install --deps-only 2024-dev-1.rockspec

Running the Code

make run-lua

or:

lua init.lua

To watch for changes:

make watch-lua

Zig

Prerequisites

• Zig @ 0.13.0

Running the Code

Run:

make br-zig

Or to watch for changes:

make brw-zig

JavaScript

Prerequisites

• NodeJS @ 22.13.1 (via nvm)

Get nvm:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bash

Install & switch to 22.13.1:

nvm install 22.13.1
nvm use 22.13.1

My intent was to do this with zero dependencies, so you should just be able to run it with node (we'll see how well I keep to this).

However, if you want linting or whatever other dev stuff I made you can install dependencies:

npm i

Running the Code

node src/main.js

To watch for changes:

node --watch src/main.js

Or using fswatch via make:

make watch-js

AoC 2023

Advent of Code 2023 solutions are in the ./2023 directory.

Solutions are created in Typescript + NodeJS and Rust.

Typescript + NodeJS

It's recommended to use nvm to manage node and npm versions.

Prerequisites

• NodeJS @ v21.4.0
• Typescript @ v5.3.2

Getting Started

In the 2023 directory, install dependencies:

npm i

If you have typescript installed globally, run:

tsc

Otherwise, you can prefix the command with npx to use the binary installed in node_modules:

npx tsc

To run the compiler in watch mode:

tsc -w

Running the Code

After compiling, the transpiled JS code will be in the dist folder.

Run the program by executing the main.js file with node:

node dist/main.js

Rust

It's recommended to use rustup to manage versions, see Rust's official Getting Started page for installation instructions.

Prerequisites

• cargo @ 1.72.1

To use the Makefile and run the project in watch mode, install cargo-watch:

cargo install cargo-watch

Getting Started

In the 2023 directory, run:

cargo build

Running the Code

If you built the executable already via the previous section, you can run:

./target/debug/aoc2023

Alternatively, you can build and run the project using:

cargo watch -x run

You can also run in watch mode using:

make watch

C++

On MacOS, uses g++ which is an alias to clang.

Prerequisites

• cmake @ 3.27.7
• fswatch @ 1.17.1

To use the Makefile and run the project in watch mode, install fswatch:

brew install fswatch

Getting Started

In the 2023 directory, run:

make build-cpp

Running the Code

If you built the executable already via the previous section, you can run:

./cpp-out/aoc2023cpp

Alternatively, you can build and run the project using:

make run-cpp

You can also run in watch mode using:

make watch-cpp
