This is a Starter project for AdventOfCode, written in Dart. Feel free to use it for your own adventures with the christmas-themed puzzles!
The code is commented abundantly, but you can find an overview about the features here as well.
Please visit the AdventOfCode site and log in. After that, get your cookie from the browser, and add it to the day_generator.dart file´s session variable. This will allow the script to populate your input file.
In the root of your directory, run dart run day_generator.dart <day>
This will create an input file and a solution file with all the needed boilerplate to have a quick start. It also adds the solution to the corresponding index file, so the solution get imported into main automatically.
To add a new solution, all you have to do is add DayXX() to the day List. Running main automatically prints either all your solutions, or just the last one, depending on your settings.
You can run the main file by running dart run main.dart or dart main.dart in the root of your directory.
By default the main file will only show the last solution. If you want to see all of them, you can use the -a or --all flag.
You can list all the command line arguments by using the -h or --help flag.
The abstract class all individual days subclass from. When constructed with the correct day, it automatically ready the corresponding input file and provides it with the InputUtil. To access it, just call input inside your class.
Automatically reads the input files and provides different methods to parse it.
.asStringto get the whole input as a single String.getPerLine()splits on\ncharacters, returning a List with single lines as elements..getPerWhitespace()splits on\sand\n, essentially returning a List with all the single characters..getBy(pattern)lets you define your own split logic. It essentially calls Dart´s native.split(pattern)
A place to store useful parsing operations, like creating a List<int> from a List<String>. There will be a lot of opportunities during AoC for you to extend this.
A helper class for 2D data, as often present in AoC. Any data can be respresented. For Integers specifically, there are convenience methods in IntegerField. For all available methods, have a look at the abundantly-documented code.
When using the Boilerplate generator, everything is done for you automatically. However, if you create a solution or input file by yourself: make sure it has a 2-digit number. Concretely, pad days 1-9 as Day01.dart for solutions and aoc01.txt for input.
Tuple enables operations on pairs/triplets etc of any type. Absolutely needed for most of the puzzles.
Collection provides many methods for ...collections... Most importantly, a groupBy and a collection equality interface.
Quiver is an awesome toolbox of helper methods for Dart. We mostly use /iterables (similar to Pythons itertools).
