Solutions in Scala for the annual Advent of Code challenge. Note: this repo is not affiliated with Advent of Code.
See earlier editions:
The Scala Advent of Code website contains:
- some explanation of our solutions to Advent of Code (adventofcode.com)
- more solutions from the community
We use Visual Studio Code with Metals to write Scala code, and scala-cli to compile and run it.
You can follow these steps to set up your environement.
After you clone the repository, open a terminal and run:
$ cd scala-advent-of-code
$ scala-cli setup-ide 2022
$ mkdir 2022/input
$ code 2022
code 2022 will open Visual Studio Code and start Metals. If not you may have to go to the Metals pane and click
the button labelled "Start Metals".
When you navigate to a file, e.g. 2022/src/day01.scala metals should index the project, and then display code lenses
above each of the main methods part1 and part2, as shown in this image:
To run a solution, first copy your input to the folder 2022/input.
Then click run in VS Code which will run the code and display the results of the program. Or debug,
which will let you pause on breakpoints, and execute expressions in the debug console.
In a terminal you can run:
$ scala-cli 2022 -M day01.part01
Compiling project (Scala 3.x.y, JVM)
Compiled project (Scala 3.x.y, JVM)
The solution is 64929
Or, to run another solution:
$ scala-cli 2022 -M <dayX>.<partX>
By default the solution programs run on our input files which are stored in the 2022/input folder.
To get your solutions you can change the content of those files in the 2022/input folder.
