Advent of Code 2022 in Kotlin

Advent of Kotlin Template

A template repository providing a simple framework for Advent of Code puzzles.

Content

After you create a new project based on the current template repository using the Use this template button, a bare minimal scaffold will appear in your GitHub account with the following structure:

.
├── README.md               README file
├── build.gradle.kts        Gradle configuration created with Kotlin DSL
├── gradle
│   └── wrapper             Gradle Wrapper
├── gradle.properties       Gradle configuration properties
├── gradlew                 *nix Gradle Wrapper script
├── gradlew.bat             Windows Gradle Wrapper script
├── src                     Generic framework utilities
└── calendar                Your very own sandbox to solve the puzzles
    └── dayX                Each day has a dedicated package for it
        ├── DayX.kt         An empty implementation class for the AoC day X [1-25]
        ├── part1.txt       AoC day X [1-25] input data for part 1
        └── part2.txt       AoC day X [1-25] input data for part 2

Note: All task input files are empty in the repository – we should not post them publicly, as Eric Wastl asks for: Tweet.

To help with that, the template contains a git hook that prevents committing anything if input files are not empty. There's also ./gradlew cleanInputs task for easy cleanup.

Please make sure not to commit input data once after you fill those files in.

Usage

Here's the overview of your daily routine while solving AoC puzzles:

1. Open ./calendar/dayX directory for the day you're solving.
2. Paste your input for part1 into part1.txt.
3. Open DayX.kt file and implement your solution in part1 method and return your answer.
4. Check your solution for part1 by running ./gradlew test --tests='dayX.DayX#part1'
5. Paste your input for part2 into part2.txt.
6. Open DayX.kt file and implement your solution in part2 method and return your answer.
7. Check your solution for part2 by running ./gradlew test --tests='dayX.DayX#part2'
8. Check both your solutions by running ./gradlew test --tests='dayX.DayX'
9. Submit your answers to AoC
10. Clean up inputs by running ./gradlew cleanInputs
11. Commit your code by running git commit -a -m "AoC DayX"
12. Push the changes by running git push
13. Profit??
