# Advent of Code 2023 (Elixir)

This repo contains my solutions for the 2023 Advent of Code. I took this opportunity to learn a new language I've been wanting to try out for some time, [Elixir](https://elixir-lang.org/), a widely used Brazilian functional programming language.

What you'll find in here is mostly comprised of DSA, text manipulation and some other shenanigans.

## Running

To run this project:

1. Install [Erlang/OTP 25 (direct link)](https://github.com/erlang/otp/releases/download/OTP-25.3.2.8/otp_win64_25.3.2.8.exe)

1. Install [Elixir (direct link)](https://github.com/elixir-lang/elixir/releases/download/v1.16.0/elixir-otp-25.exe)

1. Clone this repo

1. Run the `day` [task](#tasks)

## Tasks

### `mix day . [filename]`

This command allows you to run the solution for the specific day and part, possibly using the provided filename as input.

If filename is absent, uses `input.txt`

Examples:

```bash

# Runs solution for Day 3 Part 2, using input.txt

mix day 3.2

# Runs solution for Day 4 Part 1, using test.txt

mix day 4.1 test

```

### `mix create `

Generates the following boilerplate for solving `day`:

```

advent_of_code/

├── (other solutions)

└── day_n/

    ├── part_1.ex

    ├── part_2.ex

    ├── input.txt

    └── test.txt

```

Each solution part is also initialized with some boilerplate code:

```elixir

alias AdventOfCode.Utils

defmodule AdventOfCode.Day$day_number$.Part$part_number$ do

  def line_parser(line) do

    line

  end

  def run(file_name) do

    file_name

    |> Utils.parse_file(&line_parser/1)

  end

end

```

The `$day_number$` and `$part_number$` placeholders are replaced with the proper values during creation.
