Goals

• have fun
• learn something new
• get as many puzzles as possible to run within the time limit
• (over)use the following Java features: var, Lambda, Stream, Optional, switch expressions

Requirements

You will need JDK 17.

By default the project will look for it in your JAVA_HOME.

You can also specify your own JDK path like this when using gradle:

./gradlew <command> -Dorg.gradle.java.home=/path/to/java17

Run Unit Tests

Run all tests:

./gradlew clean test

Run a specific year:

./gradlew clean test --tests *2019*

Run a specific day:

./gradlew clean test --tests *132019*

Enable printing to stdout

Print a representation of some puzzles to stdout:

./gradlew clean test -Dprint=true

Enable interactive mode

Following days have a main method that enables a basic interactive mode:

• 13th December 2019
• 25th December 2019

Enjoy! 🕹️

TODO

• move to JUnit 5
