Solutions to the 2021 Advent of Code (https://adventofcode.com/2021/) in SWI-Prolog.
There is a script to run a specific part of a day. To run write the following command in the root of the project:
./run.ps1 <day> <part>
Where day and part are the day and the part you want to run. So for the fourth day, second part the command would be:
./run.ps1 d4 p2
You can also run a day while printing relevant trace information with the command:
./debug.ps1 <day> <part>
The project has one folder, ./dX, for each day.
Each folder contains one prolog file called dX.pl where X is the number of the day.
This file should define one predicate pY for each part Y of the day.
There is also an input.txt file which contains the input for the day.
This input is fed to the main prolog file through the stdin.
The folder ./common contains prolog modules with generally useful predicates and can be included to make life easier.
