# scala3-aoc-2024

Here we go again: [Advent of Code - 2024][aoc2024]!

To make this work you need to run ...

```bash

./mill main.test

./mill main.run

```

**Note**: This time around the focus is on learning `scala3`

and using `GitHub Copilot/emacs` and `Codeium/Windsurf` as 

much as possible (as a pair programming buddy).

**Note**: Initially the (scala3) code was formatted with 

braces. Then I decided to switch to indent. To migrate 

the code I did run `./mill main.migrate.compile` and

made heavy use of `scalafmt` and `scalafix`.

**Note**: You can install a/the pre-push hook with ...

```bash

cd ./.git/hooks

ln -s ../../hook/pre-push .

```

The hook will make sure the code is properly formatted

and linted before each push.

## What I have learned?

- Lot's about Scala3 ...

  - extensions

  - given and using

  - indent vs. braces

  - ... and (much) more

- Using `scalafmt` (for Scala3)

- Using `scalafix` (for Scala3)

- Using `breeze` to solve linear equation systems

- Using `scala-graph` to find the shortest path in a graph (or 2-dim grid)

- Using `scala-corner` to count the number of corners of regions in a 2-dim grid

- Using `Codeium` and `Windsurf` to write code
