AdventOfCode2024

Find all the solutions to the Advent of Code 2024 written in Kotlin and organized by day with the respective inputs in the resources folder.

The Nicest Day?

Day 15

The funniest day, for me, was Day 15! I had a lot of fun implementing a visual mode simulation, have look at it:

Compile the solution for Day 15 to a Jar

./gradlew clean build 
./gradlew generateJar -PmainFile=Day15.kt

Run it in the terminal

Make sure to use Java SDK 21+ for running the Jar.

java -jar build/libs/days/Day15.jar

To stop the simulation press ctrl + C.

Note that the IDE terminal may not support properly the ANSI escaping sequence which makes the simulation output smooth. I recommend running it in iTerm2 (macOS), Windows Terminal (Windows), and GNOME Terminal (Linux) terminals.

The "Must Run" Day?

Day 14

I loved the surprise hidden in the output of the second part of Day 14! You Must Run It!

./gradlew clean build 
./gradlew generateJar -PmainFile=Day14.kt
java -jar build/libs/days/Day14.jar

Extra

Auto-generate DayX Class

This project provides the script PrepareWorkTask.kt which is handy to get started with the implementation for the solution of a new Day. It can be used with the command:

./gradlew PrepareWorkTask -Pday="day26" -Ppkg="edu.adarko22"

The script generates the Day26.kt file in the kotlin sources in the solutions module, with the predefined code structure.

Generate Runnable Jars

This project provides also the script GenerateJar.kt to generate a runnable Jar for all or a specific file:

• ./gradlew generateJar -Pall=true
• ./gradlew generateJar -PmainFile=DayX.kt

The jar files will be available in the build/libs/days/ folder.
