Advent of Code

My solutions to the Advent of Code. The source code is here.

Also includes my solutions for Project Euler. The source code is here. (It's in a private repo.)

Git submodules

Project Euler does not allow sharing solutions. Therefore, the code for Project Euler is stored in a private repository. This repository is included as a git submodule. In other words, this repository contains a link to a specific commit in that other repository.

Note the following usage instructions.

# Clone without submodules
git clone [email protected]:FWDekker/aoc.git
# Clone with submodules
git clone [email protected]:FWDekker/aoc.git --recurse-submodules

# Add missing submodules after cloning
git submodule update --init --recursive
# Update submodules to respective HEADs
git submodule update --recursive --remote

To commit changes you've made in the euler/ directory, run

cd euler; git commit

Now, the root repository will be outdated, since the local repository inside euler/ no longer matches the commit referred to by the root repository. Therefore, you'll have to commit the changes there as well (but don't fret if you forget).

Gradle sub-projects

To allow code Advent of Code and Project Euler to be built separately, but still use a common codebase, the repository has been structured using Gradle subprojects. This repository has the following subprojects:

• buildSrc: Common build logic for all subprojects.
• std: Utility and helper functions for other subprojects.
• aoc: Advent of Code.
• euler: Project Euler.

Check their respective README.mds for more information.

You can run tasks as follows:

# Run all tests in all subprojects
gradlew test
# Run all tests in subproject 'aoc'
gradlew :aoc:test
# Run tests tagged with "Foo" in subproject 'aoc'
gradlew :aoc:test -Pkotest.tags="Foo"
