Advent of Code 2018

This is a repository of my solutions to the 2018 Advent of Code problems. I will be doing these in Pony.

About the Code

I created some helper code based on my experience with last year's AoC. My solutions to this years problems will probably all use this library.

Building the Solution

Each day's solution lives in a directory that is named for the day (day1, day2, etc). You will need to have the Pony compiler and Stable (the Pony dependency manager installed) in order to build the solutions. To build a solution, go into its directory and run the following commands:

stable fetch
stable env ponyc

This will create an executable with the same name as the directory that you are in.

Running the Solution

The solution executables take two arguments:

1. the name of the input file
2. the part that you want to run (1 or 2)

For example, if you wanted to run part 2 of the day 7 solution on the file ex7-4.txt you would run the following command:

./day7 ex7-4.txt 2
