This repo is built to host my solutions to advent of code puzzles. All days are written in Rust.
Generally speaking, I'm trying to stick to standard library. This is a learning exercise for me & I don't want an external crate to magically do all the work for me. I do make an exception for itertools, is which is de facto part of the standard library as far as I'm concerned. On odd days I'll use other crates too, e.g. the MD-5 crate for 2015/day_04.
I only started in 2021 and did my first year in Python, because I didn't know any better! In fairness, Python is a great language to do AoC, but I discovered Rust shortly after finishing that year and switched allegiance.
Each day is it's own binary which can be found in subfolders. Go here to run (or test) the days, and get the actual answers.
- 2015
- 2016
- 2017
- 2018
- 2019 - not yet started
- 2020 - not yet started, I do have some solutions here from when I was starting out. They need to be re-written in the standard format and generally made less bad
- 2021 - not yet started, although I do have a python repo
- 2022
- 2023
- 2024
In addition to the days themselves, this top-level folder contains a command line runner application that will time profile the days in a selected year.
I also have a sub-application that will look for any missing input files and download them automatically. For more info, see here.
Finally, I have a template folder with a template of a day for quickly getting another day added. There's not much of interest in here.
To start, you need 🦀 Rust installed 🦀
- Performance profiler: at the root directory, run
cargo run --releaseN.B. This won't output any answers, just the calc runtime - Run a day: navigate to the relevant directory, e.g.
cd 2015/day_01, and thencargo run --release - Test a day: Most days have tests based on the example cases given in the problem description.
To run these, navigate to the day directory & run
cargo test
Not the most streamlined process, this may change:
- Copy the template folder to the new day e.g.
cp -r template 2015/day_01 - Edit the package name in the Cargo.toml file for the newly copied day. The name format is
day_yyyy_dd - Uncomment the newly added day in the top-level app's Cargo.toml
- Update the relevant array in src/days.rs to include the new day. Note you will need to increase the size of the array as well as uncommenting the day line
- Download the inputs by running
cargo aoc-inputs. This needs to be installed first, see here for more info - From the root folder, run the main app to check the new day shows up and runs without error
cargo run --release - Navigate to the new day & start coding 😣
Adding a new year will be a bit more work over and above these steps
