# AdventOfCode



Advent of Code puzzle solutions in Elixir. It's work in progress and starting year 2015 to 2022, random days are attempted.



## Code Organization



All solution modules reside in `lib//day_.ex` and associated tests have the same structure in `test/` folder. Input files are in `lib/data/inputs/_.txt`.



## Stubs



To make the experience boilerplate-free and give all solutions uniform (more or less) structure, type `mix gen --year  --day ` or `mix gen  ` to have the structure and stub generated. Optionally, if you have `COOKIE` environment variable storing your cookie then it will download the input file and add the title on the moduledocs for you. Type `mix help gen` for more.



To solve the problem for a particular year/day, type in `mix solve --year  --day ` or `mix solve  ` and you will see the result of the mentioned `year/day` if it is valid and has been solved. Type `mix help solve` for more.



## Introducing a new year



During December 1 of a new year (if Advent of Code is happening that year), the following steps should be taken (this should be more streamlined in future):



* Create a new folder `XXXX` (in year format) under `/lib` or `/test`

* Update the `@latest_year` attribute on `advent_of_code.ex`

* Double check your session cookie (in case you're using it)



All commands should work from then on.



## Testing



run `mix test` to ensure all solutions are working okay. To run test for a particular year and day, type `mix test --only y`. For example: `mix test --only y1501` tests for `2015` as year and `1` as day.



## Updating README and Stats



If you want to update the `README.md` (i.e. this file) please do not update `README.me` directly, instead update the static content (not stats related) on `priv/partials/readme_content.md` and then run `mix readme` to regenerate this file.



The stats, both in `/README.md` and the bottom part of `README.md` are autogenerated by pulling from the live code state. To keep the stats updated, run `mix update_stats` command. This does the following two things:



* Runs `mix gen_stats` to update the relevant `README.md` so that the latest stats are always displayed.

* Runs `mix gen_readme` to update the main `README.md` to reflect all the stars.

* Runs `mix gen_tags` to update `wiki/tags.md` with latest tag summary

* Runs `mix gen_difficulties` to update `wiki/difficulties.md` with latest difficulty summary



Note that you can call those commands independently and also set up pre-commit hooks to run it for you.



## Pages



* [tags.md](/wiki/tags.md) contains information about tags, a loose attempt to have an idea of nature (i.e. algorithms, output type, input size etc) of puzzles

* [difficulties.md](/wiki/difficulties.md) contains information about relative difficulties, marked with :snowflake: (higher number of icons represent higher difficulty)

* Each year has its own `README.md` to have summarized information of that year. Those pages are:

    - [2015/README.md](/lib/2015/README.md)

    - [2016/README.md](/lib/2016/README.md)

    - [2017/README.md](/lib/2017/README.md)

    - [2018/README.md](/lib/2018/README.md)

    - [2019/README.md](/lib/2019/README.md)

    - [2020/README.md](/lib/2020/README.md)

    - [2021/README.md](/lib/2021/README.md)

    - [2022/README.md](/lib/2022/README.md)

    - [2023/README.md](/lib/2023/README.md)



Note: All files mentioned above are autogenerated and are created by running `mix update_stats` task.
