in Kotlin!

• Koin (for day resolution)
• JGraphT (for day 25)
• OkHTTP3 (for downloading the puzzle input)
• kotlinx-coroutines (for running stuff in parallel)
• kotlinx-serialization (for (de-)serializing persistent data)

1. Place puzzle input in a file named day<num>.txt in src/main/resources.
2. Run the main function in dev.mtib.aoc23.AoC.kt with the day number as argument.

or build the jar and run it:

gradle aocJar
java -jar app/build/libs/aoc.jar <day>

You can also move .env.example to .env and fill in your session cookie to automatically download the puzzle input. You may also be required to have openscad in the path.
