the Solutions\n\nSince I created separate repositories for the years 2021 and 2022, they have been added as git submodules. Additionally,\nthe 2023 solutions depend on my own C++ libraries, which are also included as git submodules. To clone this repository\nwith the submodules, use the following command:\n\n```bash\ngit clone --recurse-submodules https://github.com/ColeTrammer/adventofcode.git\n```\n\n### C++ Code Organization\n\nThe source code is located in the `src` directory. Each day has a solution file `$year/$day.cpp`, in a directory of the\nform `01`, `02`, etc.\n\n```bash\ncmake --preset clang_release_default\ncmake --build --preset clang_release_default\n\nexport PATH=\"$(realpath ./build/clang/release):$PATH\"\nexport DAY=01\nexport YEAR=2023\n\naoc -y $YEAR -d $DAY\n```\n\nThe input files are located in the `input` directory. The solution by default reads a file named\n`input/$YEAR/input_$DAY.txt` in the current working directory, but can be changed by passing the path to the input file\nas a command line argument:\n\n```bash\naoc -y $YEAR -d $DAY -i input.txt\n```\n\nTo get the solution to part b, pass the `-b` flag:\n\n```bash\naoc -y $YEAR -d $DAY -b\n```\n\nTo run against the problem provided sample input (named `$YEAR/test_$DAY.txt`), pass the `-t` flag:\n\n```bash\naoc -y $YEAR -d $DAY -t\n```\n\n### Utility Scripts\n\nThe `scripts` directory contains a number of utility scripts for interacting with the advent of code website. The\nscripts require an environment variable named `AOC_SESSION` to be set to the value of the `session` cookie on the advent\nof code website. The scripts perform the following functions:\n\n| Script Name | Description |\n| ------------- | ---------------------------------------------------------------------------------------------- |\n| `download.sh` | Downloads the input file for the given year and day. |\n| `new.sh` | Add source code and input stubs for solving a new problem day. |\n| `open.sh` | Opens the advent of code website for the given year, day and part in the default browser. |\n| `start.sh` | Calls `new.sh`, and then `open.sh` and `download.sh` as soon as the problem becomes available. |\n| `submit.sh` | Submits the solution for the given year and day. The solution is provided on stdin. |\n\n### 2022 Past Solutions\n\nThe rust solutions for 2022 are located in the `adventofcode2022` directory. Each day has its own rust project, named\n`day01`, `day02`, etc. To compile and run a solution, use the following commands:\n\n```bash\nDAY=01\ncd adventofcode2022/day$DAY\ncargo update # This may be required if the Cargo.lock file is out of date\ncargo run --release\n```\n\nThe input files are located in the `adventofcode2022/day$DAY/input.txt` file. The solution defaults to reading a file\nnamed `input.txt` in the current working directory, but can be changed by passing the path to the input file as a\ncommand line argument:\n\n```bash\ncargo run --release -- --input input.txt\n```\n\nTo get the solution for part b, pass the `--part-b` flag:\n\n```bash\ncargo run --release -- --part-b\n```\n\nTo run against the problem provided sample input (named `test.txt`), pass the `--test` flag:\n\n```bash\ncargo run --release -- --test\n```\n\n### 2021 Past Solutions\n\nThe rust solutions for 2021 are located in the `adventofcode2021` directory. Each day has its own rust project, named `day1`,\n`day2`, etc. To compile and run a solution, use the following commands:\n\n```bash\nDAY=1\ncd adventofcode2021/day$DAY\ncargo update # This may be required if the Cargo.lock file is out of date\ncargo run --release\n```\n\nThe input files are located in the `adventofcode2021/day$DAY/input.txt` file. The solutions are hard-coded to read a\nfile named `input.txt` in the current working directory.\n\n### 2020 Past Solutions\n\nThe C++ solutions for 2020 are located in the `adventofcode2020` directory. The solutions files are named `1.cpp`, `2.cpp`,\netc. To compile and run a solution, use the following commands:\n\n```bash\nDAY=1\ncmake -S . -B build -G Ninja\ncmake --build build\n./build/$DAY\n```\n\nThe input files are hardcoded as strings in the source code.\n\n## License\n\nThis repository is licensed under the MIT license.
