# Benchmarking setup
In this folder, I run some benchmarks on everyone's code.
## How to benchmark
1. Make sure you have the appropriate software installed. You can do so by
activating the Nix shell as defined in `shell.nix`, or you can view everyone's
installation requirements in the
[software requirements](#Software-requirements) section.
2. Run benchmarks by executing the respective scripts. For example, if you
wish to benchmark Bram's code, you may run `bram.sh` in your terminal. All data
will be collected in the `data/` folder.
3. Once you have collected all the data you wanted to collect, you can open the
Jupyter Notebook by typing `jupyter notebook Benchmarks.ipynb` in the terminal.
4. In the Jupyter Notebook, evaluate all cells and gain the graphs you want.
Graphs are also stored in the `img/` folder.
## Software requirements
To create the measurements, this benchmarking setup uses
[hyperfine](https://github.com/sharkdp/hyperfine). To build the visualization,
this setup uses [Jupyter Notebooks](https://jupyter.org/) - but you can install
the dependencies listed in `requirements.txt` to get all necessary packages
installed.
Bob uses [Python](https://www.python.org/).
Bram uses [Rust](https://rust-lang.org/) at version 1.86.0.
Brechtje uses [Python](https://www.python.org/).
Sander uses [GHCup](https://www.haskell.org/ghcup/) at version 9.6.7. Haskell
typically opens as a REPL from which functions can be evaluated, so some
liberties are taken here. The script is reformatted in the `sander_hs/` folder
and compiled to a binary in order to approximate performance.

-- AOC 2025 - Sander
-- so for those wondering about how I run this Haskell code, here's the setup:
-- 1) install GHCup as instructed from https://www.haskell.org/ghcup/
-- 2) save this haskell file and your AOC input file in some directory on your computer
-- 3) rewrite the "main" function with the location of your AOC input file
-- 4) rewrite "print contents" in the "main" function to use the function(s) you've made to process the input file ("contents") from that day correctly
-- 5) run Command Prompt, go to the directory of your files (with "cd" command) and run the command "ghci AOC2025.hs"
-- 6) run command "main"
-- 7) if your functions are correct, you'll get the correct answer!
