This is a repository containing solutions for the 2023 Advent of Code (https://adventofcode.com/).
This years language of choice is 'Mojo vs Python', that is, all solutions are implemented in both languages and cross-benchmarked between Python/PyPy and Mojo implementations.
You can read a bit more about my experience with Mojo on Medium
If you would like to run this yourself, you can do it like so, from the top-level directory of the project:
$ mojo run dayXY.mojo
$ {python3|pypy3} dayXY.py
This will run the selected day. You need to paste the contents of the specific days input into dayXY.txt. The final newline should be stripped from the inputs (sorry about this, I actually cut and paste the inputs which doesn't store the final newline).
Only the standard library is required for Mojo solutions. Python solutions may require numpy.
Each days solution automatically runs Benchmarks from my system are also included in BENCHMARKS.md and BENCHMARKS-M1.md for a MacBook Pro w/M1 chip. You can run each day across all platforms and generate the benchmark summary this way:
$ for day in `seq 01 25`; do ./run.sh $day; done
$ python3 agg.py
This will create temporary all_{python3|pypy3|mojo}_{pc|mac}.txt files. Only PC (=anything other than a Mac) and Mac are supported by the run.sh script.
The vis/ directory contains visualisations code - written in Pythin, with PyGame. You can run each one directly:
$ python3 vis/dayXY.py
Running these requires the pygame package, and you will also need to download Inconsolata-SemiBold.ttf from Google Fonts and place it in the vis folder.
Visualisations can also write video to dayXX.mp4 files automatically, if you pass additional '-r' parameter.
$ python3 vis/dayXY.py -r
This requires ffmpeg binary installed. You will need to create a 'tmp' directory for the frames.
Most videos are also published to YouTube
