Advent of Code Kotlin Template

A template which will help you concentrate on the puzzle solutions. It brings

Downloading and caching of the puzzle input
A place to enter your puzzle solving code. Results are printed and the time gets measured.
Tests to check your puzzle solving code against the example data you get each day.

Setup

Click 'Use this template'
Clone your new repository
Open the project with IntelliJ Idea CE (recommended)

Set up the automatic input download

The setup process differs depending on how you are planning to execute your solutions.

Via gradle from the command line
Via the run button in IntelliJ

Either way, you will have to determine your session cookie beforehand.

The downloader tries to download the input for the current year. If you want to use this template for older puzzles you have to adjust it accordingly.

0. Determine your session cookie

Open adventofcode.com in your browser
Login
Open the developer tools
Open the storage tab
Select "Cookies" → "https://adventofcode.com"
A table will open, the row with the name "session" is the correct one, the session cookie is the string in the "Value" field

1. Via gradle from the command line

Setup (only needed once)
1. Create the file ./gradle.properties
2. Insert the line sessionCookie=yourSessionCookieWithoutQuotes
Execution for a day
- Execute ./gradlew run -Dday={day number}

Alternatively you could skip the setup and pass the cookie as a parameter: ./gradlew run -Dday={day number} -DsessionCookie={session cookie}"

2. Via the run button in IntelliJ

Open one of the Day{XY}.kt files
Click the play button next to the main function, select Modify run configuration
Insert your session cookie into the field Program arguments
Execute the day by clicking the run button again and select Run

You have to repeat this for each day. Or you edit your run configuration each day to execute a different main function.

Tests

Tests are prepared. They are written with KoTest.
Please make sure to install the KoTest IntelliJ Idea plugin from the plugin repository in the settings.

Each day you can insert the given example data and solution into the according test class. Running the tests will check if your solution will result in the correct answer.

You can execute the tests with one of these options:

Click the play button next to the test class or method (KoTest plugin required)
Select and run the according run configuration
Execute ./gradlew :app:test --tests "day{XY}.Day{XY}Test"

If you want to write more tests along the way:

For KoTests API have a look into the documentation and the list of assertions.
If you need to mock something, MockK is ready to go.
