Advent of code

This is my repo for Advent of Code. This project has morphed over the years as I've mainly used this to learn methods, languages, tooling, etc. throughout the years. For now it has converged towards running this as a CMake project focusing on C++/Python.

Status

To see the status of advent of code and what remains in order to reach some targets that I've set, update tools/event_status.py and run ninja status.

Dependencies

• Cmake
• ninja
• conan
• Probably a few more... I have not setup this properly.

Setup

# stand in root of advent-of-code
mkdir build
conan install . --build=missing --output-folder=build
cd build
cmake -G Ninja -DCMAKE_TOOLCHAIN_FILE=conan_toolchain.cmake ..

Note: I'm using some external libraries, these do not build due to my compiler flags, I brilliantly solved it by manually patching the files, but I should look into how to handle this properly so that I don't have to patch them locally.

Tips and notes

• I often use icecream in both C++ and Python to do debug statements, it's quick and neat to use. For example in Python:

from icecream import ic
a = "moo"
ic(a)

Other targets than C++ or Python

This project mainly targets C++ and Python, at the moment other target languages will have to be handled manually, and I doubt that I'll fix so that they will run unless I aim to learn that specific language for a specific year. At the moment running ninja used-file-extensions gives:

    164 cpp
     40 h
     30 py
      5 go
      5 awk
      3 hs
      1 sh
      1 md
      1 jl
      1 ipynb

Puzzle inputs

The Advent of Code creator has requested that the puzzle input shouldn't be shared, in order to handle that I've setup a subrepo that contains all my input that I'm self hosting. The structure follows this pattern:

|-- libs  : Common libraries
|   |-- 3pp  : third party libraries
|   `-- ...
|-- aoc-puzzle-inputs
|   |-- 2015
|   |   |-- day01.input
|   |   |-- day01-sample.input
|   |   `-- ...
|   |-- 2016
|   `-- ...
|-- src
|   |-- 2015
|   |   |-- day01
|   |   |-- day02
|   |   |-- ...
    |-- 2022
    |   |-- day01
    |   `-- ...
    `-- ...
|-- cmake
|-- readme.md
`-- tools

Resources

After I've completed tasks (or those days in which I won't do it or won't manage to complete them) I often browse for inspiration. Here are a few resources I've found:

• Reddit r/advent of code
• Leaderboard times, summary and stats from various years
• 450 stars: a categorization and mega-guide

Note: Since I have hosted this repository privately before I haven't been strict on emphasizing which solutions are purely my own and when I took inspiration from elsewher. The result of this is that I may have some solutions that are not entirely mine. With this in mind I have in the last years been more explicit about mentioning this in the solution.
